Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an improvement of an automatic washing machine for vegetables.

(Prior Art) Devices that automatically wash vegetables by spraying washing water from a large number of washing water spray nozzles onto vegetables transported by a conveyor have been known for a long time. Since the water was directly drained away, the amount of water used was large, resulting in high running costs, and there were other drawbacks, such as the drains being easily clogged by vegetable debris, dirt, etc. that got mixed into the washing water.

(Problems to be solved by the invention) The present invention solves these conventional drawbacks, reduces running costs by reusing washing water, and reduces the amount of vegetable debris and dirt mixed in washing water. This machine was developed for the purpose of being an automatic vegetable washer that can separate and drain vegetables.

(Means for Solving the Problems) The present invention has a water collection tank that collects washing water and a water supply tank that supplies washing water to the pump, which are equipped with a filter net below the washing unit that is equipped with a large number of washing water injection nozzles. are installed adjacent to each other through a partition wall, the water collection tank is equipped with an overflow pipe that can adjust the water level, and the water supply tank is equipped with a new water supply pipe facing the pump suction port. It is something to do.

(Embodiment) Next, the present invention will be described in detail with reference to the illustrated embodiment. 1 is a mesh-like conveyor for transporting vegetables to be washed; 2 is this conveyor 1;
This is a cleaning section provided along the The cleaning section 2 is provided with a large number of cleaning water spray nozzles 3 and 4 above and below the conveyor 1, and in this embodiment, two cleaning sections 2 are provided, one for preliminary cleaning and one for main cleaning. Of course, there may be only one.

A water collection tank 5 and a water supply tank 6 are provided below each washing section 2 so as to be adjacent to each other with a partition wall 7 interposed therebetween. The water collection tank 5 is a tank for storing the washing water collected by the inclined water collection plate 8 provided on the lower surface of the conveyor 1 of the washing section 2, and the partition wall 7 has a filtration net in its upper half. 9 is stretched, supernatant water can flow into the water supply tank 6. Water collection tank 5
An overflow pipe 10, a wash water return pipe 11, and a drain pipe 12 are provided. The overflow pipe 10 has an L-shaped pipe 13 rotatably provided outside the water collection tank 5, and by rotating this, the water level in the water collection tank 5 can be freely adjusted. The cleaning water return pipe 11 is for returning the cleaning water of the cleaning section 2 for main cleaning to the preliminary cleaning section when there are two cleaning sections 2. Also, the drain pipe 12
is a removable cylindrical member whose upper end normally protrudes above the liquid surface, but when pulled out, all of the water in the water collection tank 5 can be drained.
On the other hand, the pump suction port 1 of the pump 14 is provided in the water tank 6.
5 is provided. This pump suction port 15 is equipped with a strainer 16 for preventing the suction of vegetable fragments, etc., and a fresh water supply pipe 17 is provided facing it. The pump 14 simultaneously sucks in new cleaning water supplied from the water supply pipe 17 and the water in the water supply tank 6, and sprays the water from the aforementioned cleaning water injection nozzles 3 and 4 to perform cleaning.

(Function) The device configured as described above performs cleaning by spraying cleaning water from a large number of cleaning water injection nozzles 3 and 4 in the cleaning section 2 while vegetables are placed on the conveyor 1 and moved. is the same as that of conventional washing machines of this type. However, in the present invention, the washing water is collected in the water collecting tank 5 by the water collecting plate 8, and the soil adhering to the vegetables is settled at the bottom, and the supernatant water is passed through the filtering net 9 of the partition wall 7. It flows into the water tank 6. At the same time, vegetable fragments and the like floating on the water surface of the water collection tank 5 are discharged from the overflow pipe 10 and collected by a strainer or the like (not shown). The pump 14 sucks the cleaning water, which has been purified in this way by removing vegetable debris and dirt, and which has flowed into the water tank 6 from the pump suction port 15.
The cleaning water is injected from the cleaning water injection nozzles 3 and 4, and since a new cleaning water supply pipe 17 is provided facing the pump suction port 15, the newly supplied cleaning water is collected in the water supply tank 6. The cleaning water is sucked in without being uniformly diluted with the cleaning water, and is sprayed almost unchanged from the cleaning water injection nozzles 3 and 4. Therefore, according to the present invention, vegetables can be washed while effectively utilizing the recovered washing water and new washing water. Moreover, after pulling out the drain pipe 12 to prevent all of the collected washing water from flowing into the water tank 6, the water tank 6 is connected to the water pipe 1.
If the new washing water from 7 is filled, only the new washing water is sprayed from the washing water injection nozzles 3 and 4, and vegetables can be washed only with the new washing water.

(Effects of the invention) As is clear from the above explanation, this invention aims to reduce running costs by reusing washing water, and also ensures that vegetable fragments, soil, etc. mixed in washing water are removed. Since it is possible to separate and drain water, it has extremely great practical value as an automatic vegetable washer that eliminates the problems of the conventional method.
