BACKGROUND OF THE INVENTION
The present invention relates to a water-washing type apparatus mainly for cleaning food materials. In the specification, “water” refers to the whole liquid suitable for cleaning in the superordinate concept, and it is sometimes heated slightly.
[0002]
[Problems to be solved by the invention]
As shown in FIG. 2, this known automatic cleaning apparatus has a basic structure of a slightly long water tank 10 having an upper surface opening type. At one end 15 of the water tank, a jet water flow is ejected from the outside of the tank into the tank as indicated by an arrow 11, while compressed air blown from the peripheral surface of the laying pipe 12 is discharged from numerous small holes formed in the tank bottom surface 13. To form a bubble 14. Therefore, when an appropriate number of vegetables are put into the water tank at one end 15 of the water tank 10, these vegetables are rotated by the jet water flow 11, and each of the jet water flow pressure 11 and the breaking pressure of each bubble 14 is respectively rotated. It moves in the direction of the arrow 11 while washing off dust and dirt adhering to the surface by the impact, and finally is removed from the tank by the carry-out conveyor 17 at the other end 16 of the water tank. On the other hand, the rotating shafts 18 and 19 installed between the both side walls of the water tank rotate a large number of vanes 20 formed along the axis as shown in FIG. 3, and suck the dust that floats on the water surface is formed in the hollow shaft 18. From the hole 22, it flows out of the shaft together with water.
[0003]
Food materials used for washing are mainly vegetables such as Chinese cabbage and radish from small bulbs such as raccoon. Since the soil adhering to these vegetables is washed off and distributed locally, it is rarely used for washing to remove earth and sand, but is often used for removing stones, lint, etc. between vegetable depressions or leaves. . Recently, this kind of washing device is frequently used for salting of salted vegetables for pickles imported from abroad. However, imported vegetables have a higher adherence rate to hair, insects, wood chips and string waste than conventional vegetables. This type of device is also unreliable for removing these dusts, so there is a problem that after all, it is necessary to rely on manual dust removal.
[0004]
[Solution]
The present invention injects a jet water flow at one end of the water tank toward the stored water stored up to a set level in the water tank and aims to make the excess water amount the same for the purpose of more complete and efficient dust removal cleaning. While overflowing at the other end of the water tank to form a flow in a certain direction, innumerable bubbles are generated from the bottom surface of the one end of the water tank, and the reservoir is caused by the pressure impact of the jet water flow and the breaking impact of the bubbles. In the washer that moves the object to be cleaned toward the carry-out conveyor installed downstream of the flow while cleaning the object to be cleaned in the water, the upper end of the coarse net that isolates the jet water jet region in the water tank is Disposed higher than the stored water and temporarily stops and cleans the object to be cleaned in an isolation chamber partitioned by the coarse net, while separating the dust separated from the packaged object through the coarse net and the other end of the water tank. On the other hand, the dust to be removed from the upstream by the fine nets arranged on the front surface of the carry-out conveyor is blocked, and then the nets are retreated onto the storage water surface by the both nets so that the packaged goods are removed by the carry-out conveyor. Therefore, it is configured to be carried out of the water tank.
[0005]
In the above configuration, an isolation chamber partitioned by the coarse net is formed by sinking the coarse net in the water tank, so that an object to be cleaned is necessarily stopped in the isolation chamber and subjected to stationary cleaning for a predetermined time. As a result, the dust removal effect is improved. The coarse net refers to a mesh value through which an object to be cleaned does not pass but dust can pass. During cleaning, dust that peels off the object to be cleaned passes through the net and overflows downstream outside the tank. . In this case, the fine net arranged on the front surface of the downstream carry-out conveyor is used to catch the dust flowing down from the upstream, and then the both nets are evacuated onto the storage water surface so that the packaged goods are moved by the carry-out conveyor. Therefore, it is carried out of the water tank. Since the fine net is used to catch the soot in advance to prevent the soot from adhering to the carry-out conveyor, it is possible to prevent the dust from re-adhering to the already cleaned objects carried out of the tank by the conveyor. The “net” described in this specification is of course a net in the academic sense, but for example, a net analog having an equivalent effect such as “Sunoko” is claimed as the net.

DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the present invention is equipped with means for attaching the coarse net 30 to the water tank 10 in FIG. As shown in FIGS. 1 and 4, the means is provided with groove-type guides 31 on the wall surfaces on both sides of the inner surface of the water tank 10, and the coarse net 30 can be moved up and down by sliding these guides 31. Since the pair of wires 32 connected to the upper edge of the frame of the net 30 are engaged with the reel 35 installed on the frame 34 via the pulley 33, the reel 35 is rotated forward and backward by the motor 36 installed on the frame 34. As a result, with the rotation in one direction, the coarse net 30 closes the inside of the water tank 10 with the load of the weight block 37 to form an isolation chamber 38 having a predetermined volume.
[0008]
As shown in FIG. 5, the air pipes 40 on both sides of the water tank 10 are each provided with a number of free nozzles 41, and the injection direction by these nozzles 41 is basically the direction of the arrow 11 as already described in FIG. 2. Slightly upward, downward, further front, back, and disorder are set, so that complicated turbulence occurs in the stored water inside the isolation chamber 38 to disturb the object to be cleaned, and the jet water flow pressure 11 The dust adhering to the object to be cleaned is efficiently removed by the synergistic action with the bubble breaking pressure boiling from the bottom, and is carried downstream through the coarse net 30 as indicated by an arrow 43.
[0009]
As shown in FIGS. 6 and 7, a fine net 47 that opens and closes up and down with a shaft rod 46 as a fulcrum with respect to the frame 45 is installed on the front surface of the conveyor 17. A gear 48 fixed to one end of the shaft rod 46 and a gear 39 fixed to the shaft of the motor 36 in FIG. 4 are connected via an endless chain to form mechanical interlocking means by such connection. When the motor 36 is operated by the manual switch 70, the opening / closing operation of the coarse net 30 and the opening / closing operation of the fine net 47 are synchronized. When cleaning the object to be cleaned in the isolation chamber 38, each dust passing through the coarse net 30 can be caught by the downstream fine net 47. In order to eliminate gaps on both sides of the fine net 47, raised bodies 71 are provided on the walls on both sides of the water tank. The washed object can be automatically carried out by the carry-out conveyor 17 by the synchronous opening of the coarse net 30 and the fine net thereafter.
