[0023] When in use, the first liquid storage tank 3a contains weak acidic liquid, the second liquid storage tank 3b contains hydrogen peroxide, and the third liquid storage tank 3c and the fourth liquid storage tank 3d contain clean water. The product is automatically cleaned in three stages: acid washing, hydrogen peroxide washing and clean water rinsing.

[0024] The first stage: open the first upper water branch pipe 31a, the second upper water branch pipe 31b and the third upper water branch pipe 31c of the first liquid storage tank 3a, and close the upper water control valve 33 of the upper water branch pipe 31 connected with the second liquid storage tank 3b, the third liquid storage tank 3c and the fourth liquid storage tank 3d.

Therefore, the waste water refluxed on the three fixed reflux seats 21 all flows back to the first liquid storage tank 3a. The above process is repeated for a period of time for pickling, and then the second stage is carried out.

[0025] The second stage: open the first upper water branch pipe 31a, the second upper water branch pipe 31b and the third upper water branch pipe 31c of the second liquid storage tank 3b, and close the upper water control valve 33 of the upper water branch pipe 31 connected with the first liquid storage tank 3a, the third liquid storage tank 3c and the fourth liquid storage tank 3d.

At this time, the product is washed with hydrogen peroxide, and in the reflux process, the circulation control valve 23 on the second circulation main pipe 222b is opened, and the circulation control valves 23 on the first circulation main pipe 222a, the third circulation main pipe 222c and the fourth circulation main pipe 222d are closed. Therefore, the waste water refluxed on the three fixed reflux seats 21 all flows back to the second liquid storage tank 3b. The above process is repeated for a period of time for hydrogen peroxide washing, and then the third stage is carried out.

[0026] The third stage is two times of water washing. The first time of water washing opens the upper water control valves 33 of the first upper water branch pipe 31a, the second upper water branch pipe 31b and the third upper water branch pipe 31c of the third liquid storage tank 3c, and closes the upper water control valves 33 of the upper water branch pipes 31 connected with the first liquid storage tank 3a, the second liquid storage tank 3b and the fourth liquid storage tank 3d. The first water pump 5a, the second water pump 5b and the third water pump 5c all pump the liquid in the third liquid storage tank 3c at this time, and the first spray head 4a, the second spray head 4b and the third spray head 4c all spray the liquid in the third liquid storage tank 3c. At this time, the product is washed for the first time, and in the backflow process, the circulation control valve 23 on the third circulation main pipe 222c is opened, and the circulation control valves 23 on the first circulation main pipe 222a, the second circulation main pipe 222b and the fourth circulation main pipe 222d are closed. Therefore, the waste water backflowing on the three fixed backflow seats 21 all flows back to the third liquid storage tank 3c. The first time of water washing is performed for a period of time in this way. The second time of water washing opens the upper water control valves 33 of the first upper water branch pipe 31a, the second upper water branch pipe 31b and the third upper water branch pipe 31c of the fourth liquid storage tank 3d, and closes the rest of the upper water control valves 33. The three spray heads 4 spray the second time of product with the clean water in the fourth liquid storage tank 3d. In the backflow process, the circulation control valve 23 on the fourth circulation main pipe 222d is opened, and the rest of the circulation control valves 23 are closed. Therefore, the waste water all flows back to the fourth liquid storage tank 3d. The second time of water washing is performed for a period of time in this way.

[0027] In addition, the fixed backflow seat 21 is provided with a clamping groove. The product is placed on the fixed backflow seat 21, clamped in the clamping groove, and the top of the product abuts against the spray head 4. The inner circle of the product is larger than the size of the spray head 4. The spray head 4 has water outlets in the middle and around. The inner wall of the product is sprayed and washed from above. The cleaned water flows down the inner wall to the backflow port of the fixed backflow seat 21 and is circularly washed. The platform 2 is provided with a transparent cover 24. The transparent cover 24 is provided with a pair of opposite doors 241. The product to be cleaned is placed on the fixed backflow seat 21 of the platform 2 by opening the pair of opposite doors. The pair of opposite doors is closed during cleaning to prevent liquid from splashing out and to facilitate observation of the internal cleaning condition.

[0028] The top of the liquid storage tank 3 is provided with an opening and closing door 34 for filling liquid into the liquid storage tank 3. The bottom of the liquid storage tank 3 is provided with a drain port. A drain pipe 35 is connected to the drain port. A manual valve 36 is arranged on the drain pipe 35. The liquid in the liquid storage tank 3 is periodically drained and emptied by the manual valve 36 to replace the new liquid and concentrate the waste liquid. The bottom of the frame body 1 is provided with universal wheels 11 for convenient movement. The universal wheels 11 are provided with locking pedals. The cleaning device can be locked and fixed for use by stepping down the pedal at a specific station. The self-locking universal wheel is a prior art.
