The inherent parts that casing 21 comprises have rotor cover 40, shell 40 is stretched along its length direction by rotary drum intermediate flange 46, also comprise rotary drum high-end and than the arcuation of low side partly 40A and 40B passage 52 hole on the low wall 30 of shell and arcuation partly are communicated with the import that the rotary drum space is led in formation in the hole on the 40B, the hole 40C of arch section 40A lower curtate has formed the outlet in rotary drum space.

The inner casing part also comprises transverse partition 51, transverse partition 51 is by extending out to sidewall 27 and 28 and upper wall 29 and lower wall 30 in the middle of the 40A of rotor cover 40 and the 40B, and space part in the casing separated, the internal diameter of being made by other low-resistance material of Teflon formula closely coincide next door 51 adjacency of the entrance and exit central authorities of annular female member 61 and inner space around the projection of the hoop 60 of rotary drum with annular concave parts 61.It is to be noted especially, on the cylindrical case of the rotary drum garden of hoop two sides, bore a hole, when drum head is closed when rotated, garden hoop in the groove will seal between rotary drum and outer wall, and the guiding hot-air enters inlet 52 and enters the right side of rotary drum arrival garden hoop 60 through eyelet, along rotary drum axially and the left side of flowing out the eyelet arrival garden hoop of rotary drum enter outlet 40C.

As shown in Figure 4, sidewall 62 outside that extends in sidewall 62 by circle wall radial outward links to each other with wall 51 and forms concave portions.By also seeing among Fig. 4, garden hoop 60 is heat sink with the 40 identical formation of unperforated garden shape inner casing, and as shown in the figure, the size of groove 61 is such, moves radially when the rotary drum eccentric rotary and not wearing and tearing garden hoop.

As Fig. 5, shown in 6, sidewall 62,63 interrupts at the upside of garden shape inner casing 40, and establishes groove to hold carriage 64 on arc cover 40A top, and carriage 64 is connected to each other the end 60A and the 60B of garden hoop 60, and carriage 64 is fixed on the inwall 51 by rivet 65.In Fig. 5,6, can clearly see, overlapping and the mutual crooked stack of two ends is bound round and the garden banding of the making drum 23 that rotates in the garden, the connecting rod 66 that two ends are bound round in the connection garden passes carriage epirelief part 67 and stretches out, spring 68 is compressed in upper convex portion by nut and divides between the outside and the packing ring 69, adjustable springs is with the compress degree of adjusting garden hoop on rotary drum, rotary drum 23 must bind round in the garden in 60 and to rotate, but garden hoop 60 also need tightly be around in and makes all hot-airs axially pass through rotary drum on the rotary drum.

In Fig. 1,7,8 clear demonstrations, conduit 52 is formed by sidewall 53 and end wall 54, and end wall 54 is by the downward opening that extends in wall in the porch of arcuation part 40B.Left side cylinder 42 passes groove on the 40A of cover portion and enters the top that upper space supports rotary drum, and the right side cylinder passes that groove enters lower space to support the lower end of rotary drum among the 40A.

Gas burner 55 is installed on the casing base clothing wall 31, its left end opening part of vicinity, provide gas from suitable source of the gas by pipeline 56 afterburner, fresh air was heated enter inlet 52 by the conduit on the pedestal before, entered rotary drum and garden then and bound round the lower space that the arc casing on 60 right sides forms.As shown in Figure 1, first baffle plate 58 extends upward until being higher than burner outlet from clothing portion of casing middle deck portion 31, and another retaining pivot 59 extends downwards until the height that aligns substantially with baffle plate 58 upper ends from mesospore 30.Two baffle plates are used not only to make and add hot-air and fresh air mixing, and prevent direct path between burner flame and the inlet.Obviously, enter also available other suitable thermal source heating of fresh air of conduit.

Be higher than arch section 40A at shell roof 29, establish an opening about rotary drum upper end to wall 51 left sides, so that is communicated with plenum chamber 70 on being fixed on roof, its right side links to each other with suction air blast 71, and this suction air blast is installed on the roof 29 towards outer casing back.As shown by arrows, hot-air is by passing the upper space that perforation enters garden hoop 60 in the rotary drum.The right side especially clearly illustrates that in Fig. 1 and 3, must be at the hot-air of upper space via upper space by outlet 40C, and the 40A partly of the arc by wall 51 left sides enter the outlet of leading to the air blast plenum chamber again.According to this method, limit air stream concentrates on the upper space in rotary drum left side to prevent the cloth thing before air circulation enters outlet.

The relative horizontal tilt of rotary drum angle is about 7.5 degree.Suitably select this inclination angle to make damp item slide to low side towards the below in any case, under the hot-air influence of axially passing through, allow dry cloth product to be stranded in the rotary drum lower curtate equably.

As previously described, the device that is used to seal space between rotary drum periphery and the arcuation part 40 that Figure 12 and 13 exemplifies, O-ring hoop 60 ' be similar to closely around rotary drum 23 peripheral central O-ring hoops 60, and closely cooperate in groove 61, and the outer end of its outer end and groove separates, and these all show at Fig. 4.Be that its cross section is T-shaped outside the difference of this garden hoop, have wide flange and narrow floor, flange is closely around the internal diameter of rotary drum and floor is packed in the annular die 61.Flange as aforementioned on the hoop 60 ' internal diameter 1 of sealing garden has bigger cross section, makes the wearing and tearing of garden hoop do preferable distribution when rotary drum rotates.

As previously mentioned, garden hoop 60 ' lap 60 ' A and 60 ' B link to each other with carriage 64 on the wall 51, it is high temperature resistant that this connection fraction is specially adapted to that bind round in the garden that other plastic material of iron Fu Longshi makes, this material has low-resistance, and have lower tensile strength.Specifically, garden hoop 60 ' the connected mode of end and carriage 64 to make that iron is not imperial still closely to center on rotary drum 23 under the tendency of hot mastication.Therefore, link to each other with carriage according to aforementioned manner, an end formula two ends are passed in the backguy of also available U-shaped hook.

Shown in Figure 11,12, reach aforementioned content, garden hoop 60 ' floor in the groove of flange and arch section 40A, garden hoop is outside to be contained in the groove in first group and second group of hole 70 and 71 holes, these two groups of holes 70 and 71 along garden hoop length direction stagger form towards opposite oblique extension staggered.Therefore, extend down to the right in the hole of being somebody's turn to do group abutting aperture 70 lefts as shown in figure 12, and its right ports is to upper right extension, and on the contrary, this left hole of group abutting aperture is to upper right extension, and right ports is then extended down to the right.Particularly, first iron wire 73 continues to pass through the staggered hole in first group of hole 70, and second iron wire then continues to pass through the position, staggered hole in the 2nd group of hole 71, two iron wires alternately two sides of garden hoop longitudinal baffle (also front and back in Figure 11, or in Figure 12 about).

As shown in figure 11, the iron wire end of respectively being organized the most stomidium extension in hole by the end of garden hoop is attached at mutually together, U-shaped end 75 passes in the lasso of end, transfer again on pull bar 66, pull bar 66 passes the eyelet on the holder flange 67, spring 68 places between flange place side and the tie rod end packing ring 69, backguy circle hoop 60 ' end in opposite direction, as the front to the mode of garden hoop 60.

As shown in figure 12, iron wire 73 and 74 is as omiting as loose suitable regulating spring packing ring 69.The difference of iron wire and plastic cement garden hoop a 66 ' expander when allowing hot air circulate to pass cloth product, and the garden of permission banding is close centers on rotary drum 23 but excessively be not resisted against to tensioning two sides of hole 70 and 71.

Shown in Figure 11 and 12, each in the every and eyelet is in fact adjacent with another group eyelet, and along opposite oblique extension, so that iron wire 73 and 74 crosses one another in adjacent holes, and extend opposite compartment of terrain on the floor of garden hoop.As shown in the figure, eyelet is intersected with each other cross-section mutually in two centre of garden hoop floor usually, and makes iron wire 73 and 74 intersect adjacency in two groups of adjacent eyelets.

As foregoing, shown in Figure 14,15, be used for sealing the example of the device of rotary drum and arch section 40, O-ring hoop 60 " cross section shape and material can with O-ring hoop 60 among Figure 11,12 ' the same, difference be that iron wire passes in the floor of garden hoop so that garden hoop internal diameter closely around the mode of rotary drum 23.Therefore,, garden hoop 60 as garden hoop 60 ' like that " the outside have corresponding side adapting to opposite side and the groove outer end with annular die 61 so that allow to move radially between the two during the rotary drum rotation.

Yet, in Figure 14,15 example, 2 groups of holes 76 with 77 to garden hoop 60 ' two groups of holes 70 with 71 similar outside be each group cross one another equi-spaced apart and anti-oblique extension, each eyelet in each group in fact with the eyelet of another group in abutting connection with and towards opposite oblique extension.Though in fact in abutting connection with staggered, not cross-section mutually between eyelet, but longitudinally interlaced with each other, Figure 14 clearly illustrates that respectively organizing abutting aperture crosses one another at two faces of garden hoop floor.Therefore, bind round the extension of two sides respectively in the garden though pass the iron wire 78 and 79 of hole 76 and 77, but but these iron wire image patterns 12,13 extend at the same space like that, though the cross force that acts on the hoop of sealing garden may be uneven, but this configuration provides bigger garden hoop, and O-ring hoop internal diameter is closely around rotary drum 23 when the reverse backguy in iron wire end.

As Figure 11 point out iron wire 78 and 79 end be connected respectively on the carriage 64.

Door 33 is opened in narration drying machine complete machine operation below, closes door 35 to allow needing dry wet product to be sent in the drying machine by conveyer.Close door 33, rotary drum rotates so that the article lift-over, in rotary drum, be provided with longitudinal rib for this purpose, meanwhile, start air blast to aspirate fresh air to gas burner, fresh air passes inlet and the lower space part was heated before entering rotary drum, and hot-air passes rotary drum vertically then, by garden hoop 60(or garden hoop 60 ' or the opening of 60 ") left come out and enter upper space partly, and leave drying machine via air blast.When rotating when rotary drum nationality roller 42, the cloth product move towards the lower right side, and heated air one enters upper casing portion and promptly passes the cloth product that are dried, when hot-air leaves the rotary drum upper end, before feeding air blast, must pass the upper end of outlet 40A, after cloth product drying, stop operating, extinguish gas burner, open door 35, dry cloth product are drawn off via the rotary drum lower end, as described above, the inclination of rotary drum have rib in the cloth product via right opening discharging.
