DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a cold water treatment apparatus according to the present invention will be described in detail with reference to FIG. 1 based on an embodiment in which the present invention is embodied in a cold water treatment apparatus. FIG. 1 is a schematic side view of a cold water treatment apparatus according to an embodiment.
In FIG. 1, the cold water treatment apparatus includes a treatment tank 1 that stores salt water and a cooling tank 2 that cools water in the treatment tank 1. The treatment tank 1 is partitioned from the cooling tank 2 via the partition plate 3, and an overflow groove 3 </ b> A is formed at the upper end of the partition plate 3. Above the cooling tank 2, a refrigeration unit 5 is attached via a support frame 4. In the treatment tank 1, a plurality of treatment baskets 6 (three are shown in FIG. 1) for immersing food such as fish and meat are arranged.
Further, a compressor and a condenser constituting a refrigeration cycle are arranged in the refrigeration unit 5, and an electrical device that houses various electronic components necessary for controlling these compressors and condensers. A box is placed. Since the configuration of the refrigeration unit 5 is known, the description thereof is omitted here. The condenser in the refrigeration unit 5 is connected to a cooler 7 that is immersed in salt water in the cooling bath 2.
Further, an overflow pipe 8 is erected inside the cooling tank 2, and the overflow pipe 8 is connected to a circulation pump 10 via a connection pipe 9 that penetrates the bottom plate. The circulation pump 10 is connected to the treatment tank 1 via connection pipes 11 and 12, and the circulation pump 10 performs an action of circulating and stirring the cooling water 2 and the salt water in the treatment tank 1 in the direction of the arrow. Is.
[0010]
Then, when the compressor of the refrigeration unit 5 is operated, the refrigerant is supplied to the cooler 7, whereby the latent heat of evaporation is taken from the salt water in the treatment tank 1 and the salt water is cooled. The salt water in the treatment tank 1 is supplied to the treatment tank 1 from the overflow pipe 8 and the connecting pipes 11 and 12 by the operation of the circulation pump 10, and is returned to the cooling tank 2 through the overflow groove 3A of the partition plate 3. It is. Based on such repeated circulation of the salt water, the temperature of the salt water in the treatment tank 1 and the cooling tank 2 is maintained at the same temperature, and the temperature of the salt water is detected by a temperature sensor (not shown). When the detected temperature falls below the predetermined temperature, the compressor operation is stopped based on the detection signal from the temperature sensor, and it is detected via the temperature sensor that the temperature of the salt water has exceeded the predetermined temperature. If it has been done, the compressor is actuated again based on the detection signal from the temperature sensor.
[0011]
Next, the filter 13 submerged in the water in the cooling tank 2 will be described with reference to FIGS. FIG. 2 is a perspective view for explaining a state in which the filter mesh 14 is removed from the filter container 15. 3 and 4 are partial side views showing the upper and lower portions of the filter mesh 14 and the filter container 15.
A filter 13 that is submerged in water in the cooling tank 2 is disposed on the side of the cooler 7 of the cooling tank 2. The filter 13 includes a filter mesh 14 and a filter container 15 in order to remove dust such as fish scales in the cooling tank 2, bubbles, and the like. The lower side of the filter housing 15 is inclined so as to be separated from the cooler 7, and the filter mesh 14 can be removed from the inside as shown in FIG. The filter container 15 is provided with an opening 15c on the cooler 7 side, and a support portion 15b around the opening 15c can support the filter mesh 14.
[0012]
In this case, the filter mesh 14 is disposed so as to close the opening 15c of the filter container 15, but has a larger shape than the opening 15c, and has a mesh portion 14b and a support frame 14a that supports the mesh portion 14b. With. A dust receiving portion 16 is provided below the filter mesh 14, and the dust receiving portion 16 is positioned below the filter container 15 in a state where the filter mesh 14 is disposed in the filter container 15. As shown, dust accumulates in the dust receiver 16. A gripping part 17 for taking out is provided above the filter mesh 14, and the gripping part 17 is arranged on the upper plate of the filter container 15 as shown in FIG. Arranged in the portion 15a.
In order to form the dust receiving portion 16 and the gripping portion 17, horizontal plate portions 16 a and 17 a in which the tip G is bent by a length X1 (= 5 mm) are spot-welded above and below the filter mesh 14. The left and right sides of the filter mesh 14 are spot-welded with a U-shaped bent plate portion 14a interposed therebetween.
[0013]
When the filter mesh 14 is disposed in the filter container 15, the filter container 15 can form a slope that is separated from the cooler 7 and can receive the filter mesh 14 in an oblique state. A force is applied in the direction of arrow C by the weight of the filter mesh 14 and the filter mesh 14 comes into close contact with the inclined surface of the support portion 15b of the filter container 15, so that dust does not spill from the opening 15c. Further, by simply placing the filter mesh 14 on the inclined surface of the support portion 15b of the filter housing 15, screws, metal fittings, rails, etc. are not required and are inexpensive, and can be easily removed. Cleaning becomes easier. The dust receiving portion 16 covers the bottom of the filter container 15 and can receive dust, but the dust receiving portion 16 makes the filter mesh 14 difficult to shift in the direction of arrow E.
[0014]
When the gripping portion 17 of the filter mesh 14 is put on the upper plate portion 15a of the filter container 15, the end face of the upper plate portion 15a and the tip G of the plate portion 17a of the gripping portion 17 are caught, so that the filter mesh 14 is It is possible to prevent shifting in the D direction. Therefore, the filter mesh 14 and the filter container 15 are not fixed, but the filter mesh 14 does not come off the slope of the support portion 15 b of the filter container 15. If the tip G of the plate portion 17a is moved in the direction of arrow F, the plate portion 17a is detached from the upper plate portion 15a, so that the filter mesh 14 can be removed and cleaned. When removing, the plate portion 16a having the tip G bent by about 5 mm can prevent dust from spilling from the dust receiving portion 16.
[0015]
And since the holding part 17 above the filter mesh 14 and the dust receiving part 16 of the filter mesh 14 are vertically symmetrical, they can be put into the filter container 15 from either the holding part 17 or the dust receiving part 16. Can be installed easily. In the case of the slope of the support portion 15b of the filter container 15, the bottom surface portion of the filter container 15 may be smaller than the case-shaped filter container of the type shown in FIG. The dust receiving portion 16 that covers the portion is also made smaller and less expensive.
Further, when cleaning the entire filter 13, the upper plate portion 15 a of the filter container 15 may be held and pulled upward, but the tip G of the plate portion 17 a of the grip portion 17 is several times from the upper plate portion 15 a. Since only mm is projected, the filter mesh 14 and the filter container 15 can be taken out together without the front end G of the plate portion 17a getting in the way.
[0016]
According to the embodiment of the present invention, the processing tank 1 having water stored therein and the cooling tank 2 for cooling the water in the processing tank 1 are circulated to the processing tank 1 while cooling the water in the cooling tank 2. In the chilled water treatment apparatus, the filter 13 is disposed on the side of the cooler 7 in the cooling tank 2, and the slope below the filter container 15 is separated from the cooler 7. The slope of the filter container 15 Since the filter mesh 14 can be removed from the filter 13, the space between the lower portion of the filter 13 and the cooler 7 can be increased, and the lower portion of the filter 13 is difficult to freeze. Then, by removing the filter mesh 14 from the slope of the support portion 15b of the filter container 15, water in the filter 13 is drained from the opening 15c. Therefore, when the filter 13 is lifted, the water is not lifted together, so that the burden of cleaning work can be reduced and the decrease in water in the cooling tank 2 can be reduced.
[0017]
Note that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention.

In this way, since the plurality of filter meshes 141, 142, 143 are arranged in order on the slope of the support portion 15 b in the filter container 15, the filter on the side away from the cooler 7 in the filter container 15. When the mesh 141 is clogged with dust or the like and water no longer flows into the cooling tank 2, the filter mesh 141 can be removed and cleaned.
[0019]
Then, when the eyes of the next filter mesh 142 are clogged with dust or the like and the water does not flow to the cooling tank 2, the next filter mesh 142 can be removed and cleaned. When the next filter mesh 143 is clogged with dust or the like and the water does not flow to the cooling tank 2, the entire filter 13 is removed and cleaned, but before the filter mesh 142 is removed and cleaned, it is cleaned first. The filter mesh 141 may be reinserted into the filter container 15.
Therefore, by arranging a plurality of filter meshes 141, 142, 143 on the slope of the support portion 15b in the filter container 15 and sequentially replacing the filter meshes 141, 142, 143 that are clogged, the entire filter 13 is The need for removal and cleaning is reduced, and the time required to remove and clean the entire filter 13 is shortened compared to the case where the filter mesh 14 is one sheet. Unlike the filter mesh 14, the filter meshes 141, 142, and 143 are not provided with the dust receiving portion 16 and the gripping portion 17, but may be attached.
