[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for discharging fragile particles such as umeboshi.

[0002]

[Prior art]

 Conventionally, in order to manufacture umeboshi, the plums are soaked in a large container (barrel) for a certain period of time, and when they are shipped (fully soaked) as a product, the worker scoops them up with a large patterned net. It was transferred to a small container.

[0003]

[Problems to be solved by the device]

 In this way, granules that are easily damaged like umeboshi ─── In the present invention, granules that are easily damaged on the surface are defined as "fragile granules". It was impossible to discharge with a pipe and a pump. In other words, when the discharge pipe is thrust into a barrel that is a high place container, both fragile granules and liquid are sucked in, pass through the pump through the discharge pipe, and discharge to the receiving container as a low place container, they pass through the pump. This is because the fragile granules are greatly damaged. In addition, since valves are often installed in the middle of the discharge pipe, the cross-sectional shape of the flow path changes suddenly, causing collisions with the inner surface of the flow path, which may cause damage, and at the same time, clogging may occur. easy.

The object of the present invention is to reduce the above-mentioned heavy labor by the worker and to efficiently and efficiently lower the (lower) container from a high place container (barrel) without damaging fragile grains such as umeboshi. It is to discharge and transfer it to the container.

Still another object is to easily perform delicate discharge speed control according to the fragility of the fragile granules, the severity of damage as a product, and the like.

Another object is to prevent damage or clogging at the suction port in the high-altitude container. In addition, the end of discharge is to be performed quickly and without getting hands dirty.

[0007]

[Means for Solving the Problems]

 The present invention comprises a siphon passage for discharging the fragile granules together with the liquid from a high-place container containing a liquid and a large number of fragile granules and transferring the fragile granules to a low place container, and further, in the middle of the siphon passage. An injection part for injecting the control liquid in the reverse direction is provided, and the flow rate of the control liquid is injected from the injection part via the first pump and the flow control valve that sucks and pumps the liquid in the low-place container. And a second pump and a return path for returning the liquid in the low-place container to the high-place container.

Further, the siphon flow path is provided with a siphon destruction mechanism in the middle thereof.

[0010]

[Action]

 (According to claim 1) It is not necessary to provide a flow rate control valve (variable throttle valve, etc.) in the middle of the discharge flow path, and the shape of the inner surface of the discharge flow path is such that the cross section suddenly decreases. There is no step. As a result, the fragile particles are not damaged while passing through the discharge channel. And, of course, since the control liquid hits the fragile granules softly, it is not damaged by this. Since the flow rate of this control liquid can be controlled, it is possible to realize delicate control of the discharge rate and to efficiently discharge the liquid so that it does not damage the liquid. In addition, the second pump recirculates only the liquid to the high altitude container through the recirculation passage.

(According to the second aspect) The liquid ejected from the jet discharge part prevents the fragile particles from colliding with the tip end of the tube body, effectively prevents damage, and is smoothly sucked without clogging. .

(According to the third aspect) When the discharge work is suddenly terminated, it can be immediately stopped. And don't get your hands dirty.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

In FIG. 4 (a), the principle of the present invention is simplified, and 1 is a high-altitude container containing liquid F and a large number of fragile granules S, such as umeboshi and roe, which are large in size. A wooden or plastic or metal barrel or tank is used, and the siphon flow path 3 is used as a discharging method for discharging the fragile granules S together with the liquid F from the high place container 1 to the low place container 2. The transfer is carried out as indicated by the arrows A and B, and the control liquid is placed in the siphon flow path 3 downstream of the top portion 4 in the opposite direction (opposite to the discharge direction A) as indicated by the arrow C. It is injected and controlled so as to reduce the flow velocity in the siphon flow path 3 (indicated by arrow A).

The control liquid is injected from the control channel 5 into the siphon channel 3 at an acute angle θ. 16 shows the injection part. In other words, in FIG. 4, the flow velocity in the siphon flow channel 3 as the discharge flow channel is obtained by merging in an inverted Y shape and injecting the control liquid at an acute angle θ to hinder the flow in the direction of arrow A. Deceleration control.

FIG. 4B shows a comparative example. That is, the flow rate control valve 6 is provided in the middle of the siphon flow path 3 to control the flow speed in the direction of arrow A. However, it is easy to use umeboshi, roe and other foods. In the granular body whose surface is easily damaged, that is, in the "fragile granular body S" of the present invention, the narrow throttle portion of the flow control valve 6 cannot be passed, or even if it can be passed. It will be appreciated that the surface is likely to be scratched.

In addition, in FIG. 4 (a), when the high-place container 1 has a discharge hole in its peripheral wall or bottom wall (not shown), it can be easily discharged without using the siphon passage 3. The flow channel can be formed by connecting it to the discharge hole. At this time, however, it is also preferable to inject the control liquid in the reverse direction in the middle of the discharge flow channel to similarly control the flow rate (not shown).

In any case, it is desirable to increase / decrease the flow rate of the control flow sent in the direction of arrow C via the control flow path 5.

Next, FIG. 1 and FIG. 2 show a specific example of a discharging device for performing the discharging method described above.

The high-altitude container 1 is a sufficiently large wooden or plastic barrel or metal barrel or tank, and a siphon channel 3 is formed beyond the upper edge 1 a of the high-altitude container 1. The siphon flow path 3 is introduced (arranged) into the height container 1 from a part of the upper casing 7 attached to the upper edge 1a of the height container 1 (in the illustrated example) and the upper casing 7. Flexible suction pipe 8, a discharge flow path portion 10 in a lower casing 9 arranged below, a pipe 11 connecting the upper casing 7 and the lower casing 9, a lower casing 9 and a low place container 2 And a pipe 12 with an on-off valve 13 for discharge that connects the

In this way, the flow control valves are completely omitted in the middle of the siphon flow path 3, and instead, in the injection section 16 in the lower casing 9, the reverse flow injection flow rate in which the control liquid is injected in the reverse direction. The control means G is provided.

The backflow injection flow rate control means G will be described in detail. 5 is a cross-sectional front view of the lower casing 9, FIG. 6 is a front external view, and FIG. 9 is a cross-sectional plan view of an essential part. In FIGS. 5 to 7, and FIGS. Numeral 9 has a structure of upper and lower two floors, and includes a first pump 21 for sucking and pumping the liquid (only) in the low-place container 2, and a control flow having a flow rate control valve 14, a check valve 15 and a filter 17. In the upper chamber 9a of the lower casing 9, the passage 5 merges with the siphon flow passage 3 in an inverted Y shape. This joining part corresponds to the injection part 16. The back-flow injection flow rate control means G is thus composed of the first pump 21, the flow rate control valve 14, the check valve 15, the filter 17, etc., the control flow path 5, and the first pump 21 drive motor (not shown). That is, the speed at which the siphon flow path 3 flows down (exhausts) increases or decreases depending on changes in the liquid level in the high-altitude container 1 and the mixing ratio of the fragile particles S. Can be controlled.

By the way, as the flow control valve 14, a three-way valve 18 is used in the illustrated example, and is connected to a return flow passage 19 described later by a branch flow passage 20.

In addition, as for the pipe shape of the injection part 16, the siphon flow path 3 is linear and the control flow path 5 merges from the side in (a) of FIG. 4, but in FIG. 1 and FIG. The channel 5 is straight and the siphon channel 3 is curved to the side (any of these can be selected freely).

In the upper chamber 9a of the lower casing 9, a part of the siphon passage 3 forms an intermediate empty chamber 22 for deceleration. The downstream side of the intermediate empty chamber 22 communicates with the low pressure container 2 through the pipe 12. A plurality of slits, a net, punching metal, a large number of holes or the like are formed on a part of the wall surface forming the intermediate chamber 22 to separate a part of the liquid flowing in the intermediate chamber 22 from each other. To the low-level container 2 by being led to the separation and discharge path 23 in FIG.

That is, inside the liquid F and the fragile granules S flowing in the sunphone channel 3, on the downstream side of the injection section 16 in which the control liquid is injected from the backflow injection flow rate control means G into the siphon channel 3. Then, a part of the liquid is discharged to the separation discharge path 23 through the separation wall portion 24 such as the slit, and the flow rate (flow velocity) of the pipe 12 is reduced to prevent the fragile granules S from being damaged.

Next, the return path 19 is for returning the liquid (only) in the low place container 2 to the high place container 1, and has a filter 25, a second pump 26, and a check valve 27. A pipe 28 penetrating the lower casing 9 and connected to the upper casing 7 for communication, a part of the upper casing 7, a flexible return pipe 29, and the like. A flap valve (not shown) is attached to the tip of the reflux pipe 29 to prevent the flow in the direction opposite to the reflux.

The second pump 26 is controlled so as to operate when the liquid level of the low-place container 2 rises to a predetermined value (upper limit) and stop when it drops to another predetermined value (lower limit). That is, a level sensor is attached. As described above, in the branch flow passage 20, the flow separated from the first pump 21 and the three-way valve 18 (flow control valve 14) flows into the reflux passage 19 and the liquid is refluxed to the high-place container 1. There is.

Next, FIG. 8 shows the suction end 30 of the siphon flow path 3 that opens into the high-place container 1. Specifically, in (a) of FIG. 8 and FIGS. 1 and 2, A pipe body 31 and an outer envelope wall portion 32 that surrounds the pipe body 31 from the outside are provided, and a jet discharge portion 33 is formed in an annular shape between the tip edge of the outer envelope wall portion 32 and the tip edge of the pipe body 31. There is.

Reference numeral 34 is a jet flow passage formed of a flexible pipe branched from the return passage 19 in the upper casing 7. The tip of the jet flow passage 34 is connected to the outer envelope wall portion 32 so that the jet flow passage 34 is spirally ejected from the jet discharge portion 33 and is fragile in the liquid F as shown by arrows E and K in FIG. The particles S are guided so as to be sucked in as shown by an arrow H without colliding with the tip edge of the tube body 31.

In this way, the ejection end portion that prevents the suction end 30 of the siphon flow path 3 (flexible suction pipe 8) from colliding with the pipe body 31 and the fragile granules S on the tip edge of the pipe body. 33 is provided, the synergistic effect with the control of the delicate low-speed flow by the backflow injection flow rate control means G for injecting the control liquid in the reverse direction from the injection part 16 in the middle of the siphon flow path 3 described above. Thus, it is possible to prevent further damage to the fragile particles S. The jet structure of FIG. 8 can also prevent clogging of the suction port.

Of course, as shown in (b) of FIG. 8, the suction portion may be configured only by the pipe body 31 (when the flow velocity is low) and expands into a trumpet shape (not shown). It is also preferable to open and reduce the flow rate at the suction site.

Next, in FIG. 1, FIG. 2 and FIG. 3, numeral 35 discharges the fragile granules S together with the liquid F from the high volume container 1 to the low volume container 2 using the siphon flow path 3 described above. It is a siphon destruction mechanism used to finish the discharge when it is desired to finish. The siphon destruction mechanism 35 is connected to the upper casing 7 provided at the top portion 4 of the siphon passage 3 so as to communicate therewith. In the illustrated example, as shown in FIG. 3, the inside of the upper casing 7 is divided into a first chamber 36, a second chamber 37, and a third chamber 38, and the first chamber 36 forms a part of the siphon flow path 3, The chamber 37 forms a part of the return passage 19, and the upper third chamber 38 is connected to the siphon breakage on-off valve 40 via a flap check valve 39 so as to form a breakage chamber. Further, 42 is a strainer which connects the first chamber 36 and the third chamber 38 to each other, and also connects the second chamber 37 and the third chamber 38 via a flap check valve 41 which is separate from the second chamber 37 and the third chamber 38. .

When the siphon flow path 3 is formed and discharge is performed, the on-off valve 40 is always closed, the valve 41 is closed, the first chamber 36 is always under negative pressure, and the second chamber is 37 always maintains a pressure higher than atmospheric pressure.

FIG. 9 shows another embodiment of the injection part 16. That is, a plurality of small holes 43 ... Are pierced through a part of the pipe 11 forming the siphon flow path 3, and these small holes 43 are jetted in the direction opposite to the flow A of the siphon flow path 3 as shown in FIG. As such, it is provided in an inclined shape. Then, the outer envelope wall portion 44 surrounds a part of the pipe 11 including the small holes 43 from the outside, and the control channel 5 is connected to the outer envelope wall portion 44 so as to communicate therewith. With this structure, damage to the fragile particles (in the vicinity of the injection part 16) can be further prevented.

The back jet flow from the first pump 21, the flow rate control valve 14, the control flow path 5, and the injection portion 16 also has a function of forming a siphon, and a siphon can be easily formed.

Needless to say, the present invention is not limited to the above-described embodiments, and various design changes are possible. For example, it is preferable that the first pump 21 is a variable pump and the backflow injection flow rate control means G is operated more reliably. Further, the low-place container 2 is not limited to the stationary type, but may be a receiving container for transportation. And, even if the low-place container 2 is installed on the same floor or ground (ground) as the high-place container 1, it is sufficient if the depth of the former is small, the former is called a low container, and the latter is a container for high places. Shall be called. In other words, the low-level container 2 and the high-level container 1 are defined as the low level and the high level, respectively. Further, the diameter of the pipe 12 may be increased to reduce the flow velocity to prevent the particle S from being damaged.

Further, in FIG. 1, it is desirable to install the discharge on-off valve 13 at a position (not shown) upstream of the branch point between the separation discharge path 23 and the discharge pipe 12 (not shown). In the case of suspension, only the two valves, the discharge on-off valve 13 and the flow control three-way valve 18, are closed. It returns to the state before the rest just by returning to 13 and 18.
