JP, 2006-280233, A Japanese Patent Application Publication No. 2007-189993

  The cleaning apparatus of Patent Document 1 has a drawback that the installation space is large because the cleaning tank extends in the transport direction.

  In addition, since the food is washed away by the water flow, the food which is easy to sink and hard to get on the water flow may not be transported smoothly and the washing may be insufficient.

  Furthermore, among foreign substances (garbage) washed away, those that are easy to float are discharged from the flow water pocket and those that are easy to sink are discharged from the outlet, but foreign substances that do not float on the water surface and are difficult to sink are Discharge from the washing tank may not be smooth.

  The washing apparatus of Patent Document 2 also requires a large installation space because there are a charging station, a washing station, and a discharging station.

  Moreover, since the washing | cleaning apparatus of this patent document 2 puts food in a basket and moves it to each station with a basket, efficient continuous processing can not be expected.

  This invention makes it a subject to be able to wash | clean efficiently efficiently also to a solid substance which is easy to sink in water, and to also need installation space small.

In order to solve the above-mentioned subject, in this invention, a solid washing device was constituted as follows.
That is, the upper, middle, and lower washing tanks, and a discharge conveyor for taking out the solid to be washed that has flowed to the bottom of the lower washing tank, and the upper, middle, and lower washing tanks It has a flush water injection device that generates a flow of water inside,
The upper washing tank is constituted by providing a flow liquid pocket for letting the washing water overflowing from the top of the cylindrical case provided on the outer periphery of the cylindrical case provided with the bottom wall where the delivery port exists,
The middle stage washing tank is configured by providing a washing water recovery chamber in communication with the outflow hole on the outer periphery of a cylindrical case provided with a bottom wall on which an outflow hole from which the washing water flows and a delivery port exist.
The washing water injection device comprises a nozzle for jetting washing water into the cylindrical case of each of the upper, middle and lower washing tanks to generate a water flow, a pump for supplying washing water to the nozzle, and the flow liquid pocket And a storage tank that filters and recovers the wash water that has flowed into the wash water recovery chamber,
The solids introduced from the upper opening of the upper washing tank are placed on the water flow generated inside the upper, middle and lower washing tanks, and are sequentially moved from the delivery port to the lower washing tank while washing It was made to take out with the said conveyor for discharge.

  It is preferable that such a solid cleaning device forms the upper, middle, and lower cleaning tanks as independent tanks, and stacks these tanks in a liquid-tight manner. It is also preferable to make the water flow generated in each of the upper, middle and lower washing tanks alternately opposite to each other, or to provide the delivery ports of each washing tank with a shutter for changing the opening area of the mouth.

  Moreover, although the thing which produces a water flow in the pipe which comprises a conveyance path and pumps the solid substance for washing | cleaning is also considered for the said conveyor for discharge, a screw conveyor is more preferable than that.

  Furthermore, the lower washing tank may be provided with a drainage port for removing sediment (foreign matter) such as sand.

  In addition, about what provides a screw conveyor as a discharge conveyor, it is good to provide the net | network of the inclination arrangement | positioning which receives the solid substance which sank in the lower stage washing tank, and guides it to the entrance of a screw conveyor.

  Further, the upper and middle wash tanks receive the water flow in the respective wash tanks and are rotated to move the solid material which has fallen to the bottom of the respective wash tanks to the delivery ports of the respective wash tanks. It is also preferable to have

  Further, the lower washing tank may be provided with a partition wall having a delivery port for dividing the inside of the lower washing tank into a washing room and a solid collection room in which the net is installed.

  The lower washing tank provided with the partition wall is also provided with a rotary blade in the inside of the washing chamber, which receives the water flow in the washing chamber and rotates to move the solid matter sunk on the partition wall to the delivery port. Preferred.

  In the cleaning apparatus of the present invention, the upper cleaning tank, the middle cleaning tank, and the lower cleaning tank are arranged vertically (vertically), so that the conventional cleaning apparatus disclosed in Patent Documents 1 and 2 listed above There is less equipment space compared to.

  In addition, since the solid to be cleaned is moved in the direction in which gravity acts, that is, from the top to the bottom, solids with high specific gravity also flow smoothly.

  Further, the foreign matter floating on the water surface flows into the flow liquid pocket of the upper washing tank and is discharged, and the sunk foreign matter is washed away by the water flow generated in the discharge path. Also, by providing an outflow hole in the middle-stage cleaning tank located between the upper and lower cleaning tanks, foreign substances floating in the tank cleaning water are also discharged from the outflow hole, and the removal efficiency of foreign substances in the cleaning water Better and more reliable cleaning. In this way, foreign substances are also removed simultaneously with the cleaning using the difference in specific gravity.

  In the case where the upper, middle and lower washing tanks are independent of each other, the number of middle washing tanks can be freely increased, and it becomes possible to meet the demand for changing the washing capacity.

  Moreover, since the dead angle of the water stream collision with respect to a solid decreases, what can make the washing | cleaning without an unevenness | corrugation expect the thing which made the water flow produced in each washing | cleaning tank of upper stage, middle stage, and the lower stage alternately turned opposite.

  Further, in the case where the delivery port is provided with a shutter, by changing the opening area of the delivery port, it is possible to adjust the washing time by changing the moving amount of the solid to the next washing tank.

  Further, in the washing chamber of the upper and middle stages and in the washing chamber of the lower washing tank provided with the partition wall, solid substances which easily sink are also reliably led to the outlet. It is difficult for stagnation and accumulation of solids inside the washing tank.

  Besides, in the case of using a screw conveyor as the discharge conveyor, even a solid substance having a weight which is difficult to convey by the water flow can be surely taken out from the washing tank. Since this screw conveyor needs to guide solids to the inlet, it is preferable to provide the net as a guide member. It is possible to move the solid material sunk to the bottom of the lower washing tank to the entrance of the screw conveyor with a movable scraper or the like, but if it is slid down and guided on the inclined net, a drive source for movement is not required.

  The washing water recovery chamber 3b is a room whose top is also separated from the outside. In addition, the flush water recovery chamber 3b is provided with a discharge port 3f connected to the liquid storage tank 9a.

  Although this cleaning water recovery chamber 3b can be provided only in a limited area of the outer periphery of the cylindrical case 3a, if it is an annular chamber surrounding the cylindrical case 3a, an area where recovery of cleaning water L containing foreign matter is wide Preferably done.

  In the lower washing tank 4, the washing water recovery chamber 4b is provided on the outer periphery of the cylindrical case 4a, and further, the cylindrical case 4a is flushed with the outflow hole 4c connecting the inside of the case to the washing water collecting chamber 4b, and washing the inside of the washing tank Partition wall 4f divided into the chamber 4d and the solid collection chamber 4e, a net 4g disposed in the solid collection chamber 4e in an inclined posture toward the start end of the discharge conveyor 7, and a bottom disposed under the net 4g It comprises a wall 4h and a drain 8 provided with a valve 8a.

  A delivery port 4j is provided in the partition wall 4f. The washing water recovery chamber 4b has the same structure as the washing water recovery chamber 3b, and the discharge port 4i is connected to the liquid storage tank 9a. The partition wall 4f is provided as necessary, and is not an essential element.

  The solid collection chamber 4e is a lower chamber, and the sunken solid slides down on the inclined tank wall and is guided onto the net 4g. The net 4g also works to sift foreign matter such as sand having a large specific gravity.

  The delivery ports of the washing tank of each stage (in the figure, 2d and 3e and 4j) are such that the installation points do not overlap in plan view of the apparatus, and the solid substance from the upper washing tank 2 is the middle washing tank 3 and the lower washing tank It does not flow through the washing chamber 4 d of the washing tank 4 to the solid collection chamber 4 e.

  A plurality of delivery ports may be provided at predetermined intervals in the circumferential direction in the washing tank of each stage. Also in this case, the delivery ports of the washing tanks in each stage are such that the installation points do not overlap in a plan view of the device.

  As shown in FIG. 5, the delivery ports 2d, 3e and 4j are provided with shutters 10 (in the figure, they are opened and closed by pivoting around the pivot shaft 10a) for changing the opening area of the delivery ports. It is also good. With this shutter 10, the residence time (that is, the washing time) of the solid in the upper washing tank 2, the middle washing tank 3, and the lower washing tank 4 can be adjusted.

  The discharge conveyor 7 may be one for placing solid matter to be cleaned on a water stream and pumping it, but here, a screw conveyor that is more preferable is illustrated. In the screw conveyor, a screw 7c rotationally driven by a motor 7b is disposed inside a pipe 7a, and the inside of the pipe 7a is a discharge path 6. The screw 7 c is inserted in the entire area of the discharge path 6.

  In addition, the upper end side of the pipe 7 a is disposed above the water surface of the washing water L in the upper washing tank 2, and the portion bent downward from the top end and opened downward is the outlet of the discharge passage 6.

  The washing water injection device 9 includes a storage tank 9a for filtering and collecting washing water that has flowed into the flow liquid pocket 2b and the washing water collection chambers 3b and 4b, and cylindrical cases 2a of upper, middle and lower washing tanks. A combination of a nozzle 9b for injecting washing water into 3a and 4a to produce a water flow, a pump 9c for pumping up the washing water in the liquid storage tank 9a and supplying it to the nozzle 9b, and a valve 9d are combined.

  A plurality of nozzles 9b are provided in each of the cylindrical cases 2a, 3a and 4a of the upper, middle and lower washing tanks respectively. The direction of the nozzles 9b is set for each washing tank in each stage so that the direction of the water flow generated in the washing tank in each stage is alternately opposite.

  For example, in the case of the illustrated washing apparatus, the nozzles 9b provided in the upper and lower washing tanks and the cylindrical cases 2a and 4a of the lower washing tank form a counterclockwise water flow in the cylindrical case 2a and 4a in plan view of the apparatus. The nozzle 9b attached to the cylindrical case 3a of the middle stage washing tank is attached so that a clockwise water flow is formed in the cylindrical case 3a in plan view of the device.

  Depending on the height of each cleaning tank, the nozzles 9b may be provided at different heights with respect to the upper, middle, and lower cleaning tanks as in the illustrated cleaning apparatus, The washing effect by the water flow is preferably enhanced.

  The valve 9d regulates the supply amount of washing water pumped by the pump 9c. The valve 9d is provided when adjustment of the strength of the water flow or the amount of water is required, and is not essential.

  In the illustrated cleaning apparatus, a conveyor 11 for conveying the cleaned solids to the lower part of the outlet of the discharge path 6 is provided. The conveyor 11 may be a known belt conveyor or the like. This conveyor 11 is only a preferred element.

  Reference numeral 12 in FIG. 1 denotes a filter, and foreign substances in the washing water collected in the liquid storage tank 9a are removed by the filter 12.

  Reference numeral 13 in FIG. 1 denotes a valve incorporated in the flush water recovery passage from the discharge ports 2e, 3f, 4i to the liquid storage tank 9a. By adjusting the discharge amount by the valve 13, the foreign material intake situation is controlled.

  The illustrated solid substance washing apparatus 1 configured in this way is driven along the inner surfaces of the cylindrical cases 2a, 3a, 4a in the upper, middle, and lower washing tanks 2, 3, 4 by driving the pump 9c. Under this circumstance, a solid to be washed is introduced into the upper opening of the upper washing tank 2.

  The solid matter is washed while moving in the upper washing tank 2 while being carried by the water flow. Then, among the foreign substances washed out here, those having a small specific gravity flow into the liquid storage tank 9a via the flow liquid pocket 2b together with the washing water overflowed in the cylindrical case 2a, and are removed by the filter 12.

  Further, the foreign matter having a large specific gravity sinks in the upper washing tank 2 together with the solid substance being washed and flows from the delivery port 2 d to the middle washing tank 3.

  Next, the solid matter moved to the middle-stage washing tank 3 is washed while flowing on the water flow opposite to the water flow in the upper washing tank 2, and at this stage, the foreign matter which tends to float in the washing water in the tank is the discharge hole 3c. The water is carried to the washing water flowing out from the water, flows into the storage tank 9a via the washing water recovery chamber 3b, and is removed by the filter 12.

Thereafter, the solid material which has sunk in the middle stage washing tank 3 flows from the delivery port 3e to the washing chamber 4d of the lower stage washing tank 4 and is washed while moving on the water flow opposite to the water flow in the middle stage washing tank 3 It flows from the delivery port 4j to the solid collection chamber 4e.

  Then, it is sunk in the solid collection chamber 4e and guided to the inclined tank wall and the net 4g, and collected at the start end of the discharge conveyor 7. In addition, foreign matter such as sand which has sunk with the solid matter passes through the net 4g and is deposited on the bottom wall 4h until it is discharged from the drainage port 8.

  The solid collected at the beginning of the discharge conveyor 7 is conveyed by the screw 7 c to rise in the discharge path 6 and discharged onto the conveyor 11 from the outlet of the discharge path 6. The cleaning is complete.

  As described above, since the washing is performed by charging the solid substance into the washing tanks connected in a row, the installation space can be reduced as compared with the conventional washing apparatus.

  In addition, since the solid to be washed is moved in the direction in which gravity acts, the solid having a large specific gravity can also be washed without any problem.

  In addition, foreign matter floating on the surface of the wash water, foreign matter floating in the wash water, and foreign matter sunk in the wash tank are discharged to each other, so the removal efficiency of the foreign matter in the wash water is improved and the reliability of the wash is ensured. Sex also increases.

  In addition, the illustrated cleaning apparatus can increase the number of middle-stage cleaning tanks 3 installed as needed, and enables stepwise setting of the cleaning capability.

  In addition, it can utilize also for washing | cleaning of the machine parts in which solid materials other than cut food, for example, scraps, oil, etc. have adhered, a screw, etc.

  FIG. 6 shows another form of the device of the present invention. The solid matter washing apparatus 1 of FIG. 6 has the rotary wings 14 installed inside the upper, middle and lower washing tanks 2, 3 and 4, and this part is different from the solid matter washing apparatus of FIG.

  The rotary wings 14 are preferable because they are detachable from each cleaning tank and easy to maintain or clean the apparatus.

  As shown in FIG. 9, the rotary wings 14 are provided with a plurality of vanes 14b attached radially at a constant pitch in the circumferential direction on the outer periphery of a support shaft 14a.

  A shaft hole 15 is provided at the center of the bottom walls 2c and 3d of the upper and middle washing tanks 2 and 3 and a partition wall 4f provided inside the lower washing tank 4, as shown in FIG. The support shaft 14 a is inserted into the hole 15, and the rotary wing 14 is rotatably supported.

  The slat 14b may be in contact with the bottom wall 2c, 3d or the partition wall 4f of the washing tank, but at a position slightly floating from the bottom wall 2c, 3d or the partition wall 4f (for friction avoidance between the bottom wall Holding at a position where a gap is formed) is preferable because the rotational resistance of the rotary wing 14 is suppressed to a low level.

  The outer end of the blade 14b extends near the inner periphery of the cylindrical case of the upper, middle, and lower washing tanks 2, 3, and 4, and each of the plurality of blades 14b is a washing tank 2, 3, 3, It is pushed in one direction by the vortices generated in 4.

  As a result, the rotary wing 14 is rotated with the support shaft 14a as a fulcrum, and the blade 14b pushes and moves the solid matter sunk on the bottom walls 2c and 3d and the partition wall 4f in the rotational direction. Therefore, the solids stay inside the washing tank and reach the delivery ports 2d, 3e, 4j without being deposited, and then flow to the discharge path 6 side.

  In the apparatus of FIG. 6, the nozzle 9b corresponding to the blade 14b is disposed at a position where the jet water directly strikes the blade 14b. Further, the nozzle 9b is shaped such that the tip does not enter the cleaning tank in order to avoid interference with the blade 14b.

  The illustrated solid washing apparatus provided with the rotary wings 14 can also be provided with the shutter 10 described above. If the shutter 10 is installed on the lower surface side of the bottom walls 2c and 3d and the partition wall 4f, the installation of the rotary wings 14 can be performed without any problem.

  The lower washing tank 4 may be a tank in which the partition wall 4 f is not installed. In that form, the lower washing tank 4 is such that the rotary wings 14 and the shutters 10 do not exist.

  In the cleaning apparatus of the present invention, the inside of the same drum may be divided into upper and lower portions by a partition plate to create a large cleaning tank.
