  Hereinafter, a preferred embodiment of a pellet combustion apparatus according to the present invention will be described with reference to the drawings.

  The pellet combustion apparatus according to the present invention improves the combustion efficiency by dividing the pellet supplied from the inside of the combustion chamber and exhausting air into the pellet to be burned by dividing it from the side and the bottom. As shown in FIGS. 1 and 2, a supply pipe (101) for supplying pellets to the inside of the combustion chamber (10), a support plate horizontally mounted inside the combustion chamber (10) and through which a plurality of through holes (111) are passed. (110), a pellet placed between the supply pipe (101) and the support plate (110) and dropped from the supply pipe (101) is accommodated therein, and the lower end is separated from the support plate (110) by a predetermined distance. A distribution unit (200) including a distribution port (210) that moves along an upper portion of the support plate (110), and is disposed and supported along at least one of both sides of the support plate (110). A channel (300) in which a plurality of injection holes (301) are perforated on one surface standing adjacent to the rate (110), a blower for injecting air into the lower part of the support plate (110) and the inside of the channel (300) Includes tube (400).

  Accordingly, the pellets dropped from the supply pipe (101) are stacked on the distribution port (210) and then discharged downward along the movement of the distribution port (210) and spread widely on the support plate (110). ) Is effectively burned in contact with the air injected through the through hole (111) and the injection hole (301).

Further details will be described.
First, a pellet combustion apparatus (100) according to the present invention is disposed in a combustion chamber (10) such as a boiler, and the combustion chamber (10) is divided into a body (not shown) such as a boiler. A cover (11) that opens and closes one side of the combustion chamber (10) can be provided so that the pellet combustion apparatus (100) provided and disposed inside the combustion chamber (10) can be maintained and repaired.

  The supply pipe (101) supplies pellets into the combustion chamber (10). As shown in FIG. 1, the supply pipe (101) penetrates from the outside into the combustion chamber (10) and the end moves to the distribution port (210). At the same time as the start point, it is extended to the upper part of the initial position that is the end point. Therefore, the pellet discharged from the end of the supply pipe (101) falls into the distribution port (210).

  The support plate (110) is where the pellets are seated and burned, and is horizontally mounted inside the combustion chamber (10), and a plurality of through holes (111) are penetrated. Therefore, the pellets seated on the support plate (110) are supplied with the air injected through the through hole (111) and are effectively burned completely, and the remaining ash is discharged downward through the through hole (111). Is done.

  Such a support plate (110) preferably has a rectangular shape whose plane is long in one direction as shown in FIGS. 1 to 3, and is supported by a support member (120). The support member (120) is a guide rail. Arrived at (130).

  The support member (120) supports the support plate (110) and collects ash in one place and discharges the ash to the outside. Preferably, the upper ends on both sides are lower portions on both sides in the length direction of the support plate (110). It includes a tilted plate (121) that is coupled and inclined downward from the upper ends of the both sides downward to the center of the support plate and the lower end continues along the length of the support plate (110).

  That is, the support member (120) not only supports the support plate (110), but also surrounds the lower portion of the support plate (110), and extends along the longitudinal direction at the center lower portion where the inclined plate (121) continues. Thus, the ash collection space (123) is formed, and the ash dropped through the through hole (111) slides along the inclined plate (121) and accumulates in the ash collection space (123).

  Preferably, the ash discharge rod (141) is extended along the inner center of the support member (120) in which the ash collection space (123) is formed, and the screw (143) is attached to the outer peripheral surface; Further included is an ash discharge motor (145) that provides rotational force to the discharge rod (141).

  At this time, the ash discharge motor (145) is arranged outside the combustion chamber (10) and connects one side wall of the support member (120), that is, the side wall connecting the tip of the inclined plate (121) on the ash discharge motor (145) side. (See 124, FIG. 8 or FIG. 9), the ash discharge pipe (147) is extended so as to be exposed to the outside of the combustion chamber (10), and the ash discharge rod (141) is connected to the ash discharge pipe (147). Is connected to an ash discharge motor (145) outside the combustion chamber (10).

  Accordingly, when the rotational force is transmitted from the ash discharge motor (145) and the ash discharge rod (141) rotates, the ash loaded in the ash collection space (123) is transferred to the ash discharge pipe (147) according to the rotation of the screw (143). ), Passes through the ash discharge pipe (147), and is discharged to the outside.

  At this time, an ash storage case (not shown) for storing the discharged ash can be further installed at the end of the ash discharge pipe (147).

  The guide rail (130) is configured to support the support member (120) by being seated on the top, and to guide the support member (120) so as to move along the length direction of the guide rail (130). The support plate (110) connected to the support member (120), the distribution unit (200) organically coupled to the support plate (110), the channel (300), etc. are taken out of the combustion chamber (10), It is easy to mount it inside the combustion chamber (10), and maintenance and repair are convenient.

  Such a guide rail (130) can have various forms within the above-mentioned purpose range, and is not limited to the illustrated one.

  The distribution unit (200) distributes the pellets falling from the supply pipe (101) to the support plate (110). The distribution port (210) accommodates the pellets inside as shown in FIGS. And a moving means (220) for horizontally moving the distribution port (210) within the upper portion of the support plate (110).

  The distribution port (210) is preferably in the form of a square box opened up and down, and is arranged between the supply pipe (101) and the support plate (110), and pellets dropped from the supply pipe (101) are placed inside. The lower end is separated from the support plate (110) by a predetermined distance.

  Accordingly, the pellets dropped from the supply pipe (101) are packed in the distribution port (210) and then discharged into a spaced gap between the distribution port (210) and the support plate (110). Is laid on the upper surface of the support plate (110).

  The distribution port (210) preferably further includes a plurality of hooking rods (222) that cross the lower end of the interior.

  Therefore, the pellets stacked inside the distribution port (210) are caught on the hook rod (222) and sequentially discharged below the distribution port (210) to prevent the pellets from spilling all over the support plate (110). This improves the distribution efficiency of pellets. At this time, the hook rod (222) is more preferably rotated so that the pellet can smoothly slide between the plurality of hook rods (222).

  In addition, the distribution port (210) is preferably located at the lower end of one of the side walls perpendicular to the moving direction of the distribution port (210), particularly with respect to the direction in which the distribution port (210) moves from the initial position. And a non-combustible brush (224) extending to the support plate (110) along the lower end of the side wall placed on the wall.

  Accordingly, when the distribution port (210) moves along the upper portion of the support plate (110) by the operation of the moving means (220) as described later, the nonflammable brush (224) passes the ash on the support plate (110). The pellets are discharged to the space between the support plate (110) and the rear side wall of the distribution port (210) where the non-combustible brush is not mounted, and then sweeping down below the hole (111).

  As a result, the pellets supplied again are seated with good air permeability on the support plate (110) from which the previously left unburned ash has been removed, and smooth combustion is achieved.

  The moving means (220) substantially moves the distribution port (210), is connected horizontally to both side walls of the distribution port (210), and is a rotating shaft connecting member (221) having a thread on the inner surface. A rotation shaft (223) having a thread formed on the outer peripheral surface and coupled to the rotation shaft connecting member (221); and a distribution port moving motor (225) for providing a rotation force to the rotation shaft (223).

  At this time, the rotating shaft (223) is preferably disposed below the channel (300), but the rotating shaft connecting member (221) and the distribution port (210) are extended to the side of the distribution port (210) to be below. It is connected so as not to interfere with the channel (300) through a connecting bar (227) which is bent to a rotating shaft connecting member (221).

  A pair of rotating shafts (223) extended along the length direction of the support plate (110) on both sides of the distribution port (210) are preferably connected to the pulley (228) and the belt (229) to be distributed. The moving motor (225) is connected to only one of the pair of rotating shafts (223) and transmits the driving force to the pair of rotating shafts (223) simultaneously.

  Therefore, when the distribution port moving motor (225) rotates and the pair of rotating shafts (223) rotate in the same direction, the rotating shaft connecting member (221) follows the rotation of the thread formed on the outer peripheral surface of the rotating shaft (223). Advances in a straight line. Conversely, when the distribution port moving motor (225) rotates in the reverse direction and the pair of rotating shafts (223) rotate in the same reverse direction, the rotating shaft follows the reverse rotation of the thread formed on the outer peripheral surface of the rotating shaft (223). The connecting member (221) moves backward in a straight line. As a result, the distribution port (210) reciprocates linearly on the upper part of the support plate (110) according to the movement of the rotating shaft connecting member (221).

  Preferably, as shown in FIG. 5, the distribution port moving motor (225) is disposed outside the combustion chamber (10), and the rotating shaft (223) distributes through the cover (11) of the combustion chamber (10). A heat transfer material (13) is further included between the distribution port moving motor (225) and the cover (11) in the rotating shaft (223), connected to the port moving motor (225).

  Such a heat shielding material (13) causes the heat inside the combustion chamber (10) to flow out to the outside through the rotating shaft (223) extended to the outside, or is transmitted to the distribution port moving motor (225) to cause a failure. To prevent it from happening.

  The channel (300) is connected to the blower pipe (400) and blows air from the side into the pellets seated on the support plate (110), and preferably the interior is empty as shown in FIGS. A plurality of injection holes (301) are perforated on one side of the support plate (110) which is disposed along both sides of the support plate (110) in the longitudinal direction and is standing next to the support plate (110).

  In addition, the channel (300) further includes a plurality of passage membranes (304) that are preferably extended in layers in order to effectively induce air flow therein.

  The channel membrane (304) includes a first channel membrane (302) that provides a channel that gradually narrows up and down from the inflow portion (305) on the air duct (400) side in the channel (300), and the first channel. The second membrane (303) is provided on the upper side of the membrane (302) and provides a passage gradually extending up and down from the opposite side to the inflow portion (305).

  Therefore, the air injected into the channel (300) from the blower pipe (400) passes from the lower part of the channel (300) to the upper part via the zigzag on the side opposite to the inflow part (305) side of the channel (300). Proceeding and flowing into a plurality of injection holes (301) penetrating to the side, air is effectively blown into the side of the pellet.

  On the other hand, the air supplied from the blower pipe (400) is injected not only through the injection hole (301) of the channel (300) but also through the through hole (111) of the support plate (110). As described above, the chamber (310) is interposed between the one side end where the inflow portion of the channel (300) is provided and the lower portion of the support plate (110) and the air duct (400).

  The chamber (310) is a space where the air supplied from the blower pipe (400) is divided and accommodated, and the air moving to the channel (300) side and the lower side of the support plate (110) respectively stays there. Preferably, as shown in FIGS. 7 to 9, the interior of the chamber (310) is divided and connected to the first region (321) connected to one side end of the channel (300) and the lower part of the support plate (110). A boundary plate (320) that is divided into a second region (323), and is perforated at a position corresponding to a side edge of the boundary plate (320) in the outer wall (312) of the chamber (310), and a blower pipe (400) The boundary plate (320) is configured to adjust the air inflow rate in any one of the semicircles of the opening (315) and the opening (315) divided by the boundary plate (320). It rotates along an axis corresponding including adjustment plate (317).

  More specifically, the chamber (310) is divided into a housing (311) that is open on one side and an outer wall (312) that closes the open side, and the housing (311) is provided on both sides of the support plate (110). At the same time, the outer wall (312) is connected to the end of the air duct (400).

  The housing (311) is disposed perpendicular to the initial position of the distribution port (210) in the longitudinal ends of the support plate (110), and the upper side with respect to the same horizontal plane as the support plate (110). One side end of the channel (300), that is, the inflow portion (305, see FIG. 6) is in contact with the lower side of the support member (120) and the extended side wall (124) of the ash discharge pipe (147). Touch.

  The boundary plate (320) lies inside the housing (311), preferably so as to correspond to the side edges of the support plate (110), and the interior of the housing (311) is connected to the upper first region (321). This is divided into the lower second region (323).

  At this time, an upper inlet (322) is provided in the first region (321) to communicate with the inside of the channel (300), and a lower inlet (324) is provided in the second region (323) to support it. The inside of the supporting member (120), that is, the lower part of the supporting plate (110) is communicated through the through hole (125) that is penetrated through the side wall (124) of the member (120).

  In addition, a guide plate (325) inclined upward from the inside of the housing (311) to the inside of the support member (120) is attached to the lower inlet (324) and the through-hole (125). Air that flows into the lower portion of the support plate (110) through (324) is more effectively advanced toward the support plate (110).

  Therefore, the air supplied from the blower pipe (400) is divided into the first region (321) and the second region (323) through the opening (315) and the boundary plate (320), and the channel (300) and Proceed to the bottom of the support plate (110).

  The outer wall (312) is penetrated by the opening (315), the blower pipe (400) is connected to the outer surface, and the side edge of the boundary plate (320) is preferably at the center of the opening (315) on the inner surface. It is combined with the housing (311) so as to cross.

  At this time, the opening (315) is an adjusting means for adjusting the amount of inflow of air, and preferably an adjustment plate rotating shaft (crossing the inside of the opening (315) so as to correspond to the side end of the boundary plate (320). 316) is mounted, and an adjustment plate (317) coupled in a semicircular shape is mounted on the adjustment plate rotation shaft (316).

  Such an adjustment plate (317) rotates about the adjustment plate rotation axis (316), opens and closes the semicircular region below the opening (315), and flows into the second region (323). Adjust the amount.

  Accordingly, the air that has traveled to the lower part of the channel (300) and the support plate (110) through the first region (321) and the second region (323) passes through the injection hole (301) and the through hole (111). Simultaneously with the injection, the amount of air injected through the injection hole (301) and the through hole (111) can be adjusted differently.

  That is, if the amount of air flowing into the second region (323) is smaller than the first region (321) by adjusting the adjustment plate (317) as shown in FIG. 10, a channel is formed below the support plate (110). (300) A smaller amount of air is injected, and the through hole (111) injects a relatively smaller amount of air compared to the injection hole (301).

  This makes it possible to burn the pellets more effectively by relatively increasing the amount of air blown to the side than the amount of air blown downward to the pellets that are seated on the support plate (110) and burned.

  However, the structure of the chamber is omitted, and the air duct (400) is divided into several parts, each extending to the lower part of the channel (300) or the supporting plate (110) and extending to the lower part of the supporting plate (110). The air duct (400) may be provided with a normal valve-type air volume adjusting means (not shown) to replace the chamber (310) and the adjusting plate (317).

  Finally, a reference numeral 20 which has not been described relates to the electric heating rod, and is a means for igniting the pellets seated on the support plate (110).

  The pellet combustion apparatus according to the present invention distributes the pellets to the bottom of the combustion chamber, spreads them uniformly and burns them uniformly, and not only heats them at high temperatures, but also separates the air from the side and the bottom of the burned pellets. By blowing and effectively burning the pellets, all the pellets inside the combustion chamber can be completely burned until the pellets are again fed.

  As a result, a boiler or the like to which the pellet combustion apparatus according to the present invention is applied has a high combustion efficiency, and has the effect of reaching the set temperature within a short time and saving fuel.

Also, the pellets supplied to the inside of the distribution port can be dropped more effectively on the support plate by falling on the hook rod and distributed more effectively.
In addition, the non-combustible brush provided on one side of the lower end of the distribution port sweeps the upper surface of the support plate according to the movement of the distribution port, forcibly removes the ash of the pellets and improves the air permeability inside the combustion chamber, Combustion efficiency can be improved.

  In addition, heat inside the combustion chamber is prevented from being transmitted to the outside through the rotation shaft through the heat blocking material provided on the rotation shaft, preventing heat loss inside the combustion chamber and failure of the distribution port moving motor. be able to.

  The above description is only a preferred embodiment of the present invention, and various modifications are possible. However, if these modifications are included in the technical idea of the present invention, they should be within the scope of the present invention, and the scope of the present invention can be easily understood by those skilled in the art through the claims. it can.
