Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a water circulation device for cleaning fruits and vegetables. Background Art

[0002] In addition to being beneficial to human health, fruits and vegetables also have important significance for adjusting people's taste because they contain various organic acids, aromatic substances and various pigment components. With proper combination of fruits and vegetables in the diet, people can cook dishes with various flavors, colors, aromas and tastes. In this way, the purpose of weight loss and health care is achieved, and the taste is satisfied. Quick-frozen fruits and vegetables need to be washed, blanched and cooled before quick freezing. During the fruit and vegetable washing, the fruits and vegetables are put into the washing pool and rinsed by spraying.

[0003] Existing fruit and vegetable washing water will be mixed with dirt and impurities after use. In order to save costs and comply with the principle of environmental protection and reuse, the wastewater is usually filtered and recycled. However, when the filter screen filters the dirt and impurities in the wastewater, some of the impurities will be adsorbed on the surface of the filter screen, affecting the filtration efficiency. Therefore, it is necessary to stop the machine regularly and take out the filter screen for cleaning. This cleaning method not only leads to a large amount of manual labor, but also reduces the recycling efficiency of the washing water. Utility Model Content

[0023] Reference Figure 1-4 A fruit and vegetable washing water circulation device comprises a washing pool 1, a lower surface of the washing pool 1 is fixedly connected with a return pipe 2, one end of the return pipe 2 is fixedly installed with a worm flow sensor 3, the flow rate of the return washing water is detected by the worm flow sensor 3, one end of the worm flow sensor 3 is fixedly connected with a connecting pipe 4, the outer surface of the connecting pipe 4 is fixedly installed with a first solenoid valve 5, one end of the connecting pipe 4 is fixedly connected with a filter pipe 6, and the inner wall of the filter pipe 6 is fixedly sleeved with an annular filter screen 7;

[0024] A backwashing device is provided at one end of the filter tube 6 , and the backwashing device includes a circulation box 8 , and a side surface of the circulation box 8 is fixedly connected to one end of the filter tube 6 .

[0025] The outer surface of the filter tube 6 is fixedly installed with a second solenoid valve 81 and a third solenoid valve 82, and the other end of the filter tube 6 can be connected to a wastewater discharge pipe to facilitate the discharge of impurities. A submersible pump 83 is fixedly installed on the inner bottom wall of the circulation box 8, and the water outlet end of the submersible pump 83 is fixedly connected to an outlet pipe 84. One end of the outlet pipe 84 passes through and extends to the upper surface of the circulation box 8. A fourth solenoid valve 85 is fixedly installed on the outer surface of the outlet pipe 84. One end of the outlet pipe 84 is fixedly connected to a strip spray block 86. The lower surface of the strip spray block 86 is fixedly installed with spray heads 87 distributed in a linear array. The lower surface of the strip spray block 86 is fixedly connected to a support block 88, and the support block 88 serves to stably support the strip spray block 86.

[0026] The lower surface of the support block 88 is fixedly connected to the upper surface of the cleaning pool 1, and the outer surface of the water outlet pipe 84 is fixedly connected to a flushing pipe 89. The outer surface of the flushing pipe 89 is fixedly installed with a fifth solenoid valve 810. One end of the flushing pipe 89 is fixedly connected to the outer surface of the filter tube 6. The flushing pipe 89 serves to guide the water flow in the water outlet pipe 84 to the filter tube 6 for flushing, thereby realizing automated cleaning and reducing manual labor. The upper surface of the circulation box 8 is fixedly connected to a water adding pipe 811. A liquid level sensor 812 is fixedly installed on the inner wall of one side of the circulation box 8. The liquid level sensor 812 serves to monitor the cleaning water level inside the circulation box 8. One end of the water adding pipe 811 is connected to an external water source, thereby facilitating the replenishment of water inside the circulation box 8.

[0027] By providing a backwashing device, the impurities adsorbed on the lower surface of the annular filter screen 7 can be automatically washed and discharged from the filter tube 6, which not only reduces manual labor but also avoids repeated disassembly and assembly, thereby improving the circulation efficiency of the cleaning water.

[0028] Working principle: Step 1, the first solenoid valve 5, the second solenoid valve 81 and the fourth solenoid valve 85 are in a normally open state, the third solenoid valve 82 and the fifth solenoid valve 810 are in a normally closed state, the cleaning water in the cleaning pool 1 enters the filter tube 6 through the return pipe 2 and the connecting pipe 4, and the flow rate of the return cleaning water is detected by the worm flow sensor 3. Since the third solenoid valve 82 is in a closed state, the cleaning water enters the circulation box 8 through the filtration of the annular filter screen 7 due to water pressure reasons. The submersible pump 83 works to transport the filtered cleaning water to the strip spray block 86 through the outlet pipe 84, and finally sprays it out through the spray head 87 to clean the fruits and vegetables;

[0029] Step 2: When there are many impurities adsorbed below the annular filter, the worm flow sensor 3 detects that the water flow velocity in the return pipe 2 is reduced to a preset value, and the first solenoid valve 5, the second solenoid valve 81 and the fourth solenoid valve 85 are closed through the external PLC controller, and the third solenoid valve 82 and the fifth solenoid valve 810 are opened. At this time, the water flow of the outlet pipe 84 is transported to the filter pipe 6 through the flushing pipe 89 to flush the annular filter 7, so that the impurities adsorbed below are washed away by the water flow and discharged through the other end of the filter pipe 6;

[0030] Step three, when the impurities are discharged, close the third solenoid valve 82 and the fifth solenoid valve 810, and open the first solenoid valve 5, the second solenoid valve 81 and the fourth solenoid valve 85, so as to continue to filter and recycle the cleaning water. When the liquid level sensor 812 senses that the water level in the circulation box 8 is lower than the preset value, the circulation box 8 is replenished with water through the water adding pipe 811.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
