[0014]
In the food washing apparatus 1, a washing water circulation path 30 for returning the washing water sucked from the inside of the washing tank 10 to the inside of the washing tank 10 by the circulation pump 3 is formed. Is provided.
[0015]
This washing water filtration device 4 includes an upstream circulation pipe 31 connected to the food take-out side of the washing tank 10, a downstream circulation pipe 32 connected to the food input side of the washing tank 10, an upstream circulation pipe 31, and a downstream side. A water storage tank 40 provided between the circulation pipes 32.
A submersible pump 41 is provided inside the water storage tank 40, and a tubular mesh 42 is detachably mounted horizontally between the suction side of the submersible pump 41 and the upstream circulation pipe 31.
[0016]
A flexible hose 43 is connected to the discharge side of the submersible pump 41, and two switching pipes 45, 45 switched by a switching valve 44 (three-way valve) are connected to the flexible hose 43 in a downward direction. Bag-shaped meshes 46, 46 are respectively attached to the two switching pipes 45, 45 in a hanging state so as to be detachable.
[0017]
The two switching pipes 45 are formed in a bifurcated shape and are attached to a turning support arm 47 provided at the upper end of the water storage tank 40 so as to be disposed above the water storage tank 40. As shown, above the water storage tank 40, it is possible to rotate between the inside and the outside of the water storage tank 40.
As described above, when the switching pipes 45 and 45 are made rotatable between the inside and the outside of the water storage tank 40, the switching pipes 45 and 45 are connected to the water storage tank 40 when cleaning the inside of the water storage tank 40 or the like. If it is put outside, the switching pipes 45, 45 do not become an obstacle, and it is possible to work easily.
[0018]
The tubular mesh 42 and the bag-shaped meshes 46, 46 are formed of a mesh made of cotton, hemp, or a synthetic resin material, and a tightening string 48 having a string restraint for preventing loosening is provided at the opening. ing.
A flange 49 is provided on the upstream side circulation pipe 31 to which the tubular mesh 42 is attached, the suction side of the submersible pump 41, and the end of the two switching pipes 45, 45 to which the bag-shaped meshes 46, 46 are attached. Is formed.
Therefore, the tubular mesh 42 and the bag-like meshes 46, 46 can be prevented from coming off and securely attached by binding with the tightening string 48 while the flange 49 is wrapped around the mesh opening.
[0019]
Further, the water storage tank 40 is formed in a box shape having an open upper surface, and a wall surface facing the bag-shaped meshes 46, 46 is formed such that an inwardly-sloping inclined surface is formed so as to be narrowed inward (widened outward). 50 are formed.
This is because, when the bag-like mesh 46 is replaced, when the bag-like mesh 46, which has become heavy due to the accumulation of dirt and the like, is taken out from the water storage tank 40, the bag-like mesh 46 is pulled up so as to be displaced along the inclined surface 50. The work has been made as easy as possible.
[0020]
Further, a screen 51 in the form of a partition is detachably mounted inside the water storage tank 40 so as to surround the opening of the downstream circulation pipe 32. The screen 51 prevents the cylindrical mesh 42 and the bag-shaped mesh 46 from being sucked into the downstream circulation pipe 32.
[0021]
In the food cleaning device 1 of the present invention, a water flow is generated in the transport cleaning path 13 from the food input unit 11 to the food extraction unit 12 by the force of the air ejected from the air ejection device 18.
At the same time, the circulating pump 3 provided in the rinsing water circulation path 30 causes the rinsing water to be discharged from the downstream circulating pipe 32 to the food charging side of the cleaning tank 10 and flows into the upstream circulating pipe 31 from the food removal side of the cleaning tank 10. Therefore, a water flow is generated from the food input unit 11 to the food extraction unit 12 in the transport cleaning path 13.
[0022]
Therefore, when the food F is loaded into the food loading section 11, the food F is washed by blowing air bubbles from below, and is sent to the food take-out section 12 through the transport / cleaning path 13 by the water flow while repeatedly floating and sinking.
In this case, the floating garbage is separated by the garbage collecting net conveyor 25 just before the food take-out unit 12, then floated up in the food take-out unit 12, scooped up by the take-out conveyor 14, and conveyed on the take-out conveyor 14. It is taken down outside of the cleaning tank 10.
At this time, in the cleaning tank 10, the circulation of the cleaning water is performed between the transport cleaning path 13 and the return path 15.
[0023]
The washing water in the washing tank 10 is circulated as a whole between the washing tank 10 and the washing water circulation path 30 by the circulation pump 3. At this time, the washing water filtration device 4 provided in the washing water circulation path 30 is used. Thus, dust and dirt contained in the washing water are filtered.
[0024]
In the washing water filtration device 4, a tubular mesh 42 is previously attached between the upstream circulation pipe 31 and the submersible pump 41, and a bag-like mesh 46 is attached to each of the two switching pipes 45. The switching valve 44 is previously switched to one of the switching pipes 45.
[0025]
Then, when the cleaning water flows from the upstream circulation pipe 31 into the water storage tank 40 by the circulation pump 3, the cleaning water flows into the cylindrical mesh 42 attached between the upstream circulation pipe 31 and the circulation pump 3. Here, preliminary filtration for removing large trash is performed.
[0026]
Next, since the submersible pump 41 is provided in the water storage tank 40, the washing water sucked up by the submersible pump 41 passes through the flexible hose 43, and is then switched to one of the switching pipes switched by the switching valve 44. 45, and into a bag-shaped mesh 46 attached to the switching pipe 45.
The cleaning water from which dust, dirt, and the like have been sufficiently removed by the bag-shaped mesh 46 flows into the water storage tank 40 through the bag-shaped mesh 46.
The cleaning water in the water storage tank 40 passes through the screen 51 in the form of a screen, flows into the downstream circulation pipe 32, and then returns to the cleaning tank 10. It circulates between the washing water circulation path 30.
[0027]
As described above, the submersible pump 41 is provided in the water storage tank 40 separately from the circulation pump 3 provided in the cleaning water circulation path 30, so that the cleaning water is entirely supplied by the circulation pump 3 to the cleaning tank 10 and the cleaning water circulation path 30. In the washing water filtration device 4, the washing water can be made to flow vigorously by the submersible pump 41 and flow into the bag-like mesh 46 while being circulated between the bag-like meshes 46, thereby improving the filtering capacity of the bag-like mesh 46. Can be.
[0028]
In addition, by passing the washing water through the bag-shaped mesh 46 as described above, dust and dirt accumulate in the bag-shaped mesh 46. Need to be replaced.
At this time, if the switching valve 44 is switched to the other switching pipe 45, the washing water from the submersible pump 41 can flow into the bag-shaped mesh 46 attached to the other switching pipe 45 by itself.
This eliminates the need to stop the operation of the whole food cleaning device 1 when replacing the bag-shaped mesh 46, and enables the continuous operation of the food cleaning device 1 to improve the food cleaning capability.
It should be noted that the bag-shaped mesh 46 in which dirt, dirt, and the like are accumulated is removed from the switching pipe 45, taken out of the water storage tank 40, cleaned of dirt, dirt, and the like inside, and then attached to the switching pipe 45 again.
[0029]
【The invention's effect】
As described above, in the washing water filtering device in the food washing device of the present invention, the two-stage filtration using the tubular mesh and the bag-like mesh is performed, and the bag-like mesh is provided in the water storage tank. Since the washing water is sent by the submersible pump, the filtration ability can be improved.
[0030]
Further, since it is not necessary to stop the operation of the entire food cleaning device when replacing or cleaning the bag-shaped mesh, continuous operation of the food cleaning device is enabled, and the food cleaning capability can be improved.
