[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figure 1 As shown, multiple parts processing equipment 30 are arranged linearly in the workshop. Each parts processing equipment 30 includes a cleaning section. The automatic recycling device for cleaning fluid includes a collection tank 31, which is located below the cleaning section. The collection tank 31 is connected to the main fluid flow pipe 35 through a branch fluid flow pipe 32. Each branch fluid flow pipe is equipped with a transfer pump 33 and a valve 34. The main fluid flow pipe 35 is connected to the cleaning fluid wastewater pumping pipe 1. When the parts processing equipment 30 cleans the parts in the cleaning section, the water after cleaning the parts falls into the collection tank 31 under the action of gravity. At this time, the valve 34 is opened, and the transfer pump 33 pumps the water in the collection tank 31 into the main fluid flow pipe 35 through the branch fluid flow pipe 32.

[0037] like Figures 2-5As shown, the cleaning fluid wastewater pumping pipe 1 is fixedly connected to the outer wall of the cleaning fluid receiving tank 3. The cleaning fluid receiving tank 3 serves to receive wastewater, facilitating subsequent wastewater treatment operations. The cleaning fluid wastewater pumping pipe 1 introduces the wastewater to be treated into the cleaning fluid receiving tank 3, providing a source guarantee for the wastewater treatment process. A vacuum pump 2 is fixedly connected to the outer wall of the cleaning fluid wastewater pumping pipe 1. After the vacuum pump 2 is started, it uses its own suction force to pump the wastewater into the cleaning fluid receiving tank 3 through the cleaning fluid wastewater pumping pipe 1. This achieves automatic wastewater extraction, eliminating the need for manual wastewater handling, improving work efficiency, and reducing labor costs. Simultaneously, one automatic cleaning fluid recycling device can process multiple parts processing equipment, thereby reducing the cost of cleaning fluid treatment equipment.

[0038] A receiving tank 5 is placed at the bottom of the cleaning fluid receiving tank 3. The receiving tank 5 is used to receive water treated by the cleaning fluid receiving tank 3, which facilitates the subsequent transfer and transportation of the water. A transmission pipe 6 is fixedly connected to the outer wall of the receiving tank 5. The transmission pipe 6 can serve as a channel for the preliminary treatment of wastewater, ensuring that the wastewater can flow smoothly to the next treatment stage. A bag filter box 8 is fixedly connected to one end of the transmission pipe 6. The bag filter box 8 is an important place for the preliminary filtration of wastewater. It can play a preliminary filtration role in the wastewater and further remove some larger particulate impurities in the wastewater.

[0039] The inner wall of the bag filter box 8 is equipped with a porous filter plate 27. The porous filter plate 27 can initially intercept and filter the wastewater, allowing the wastewater to flow more evenly to the next filtration stage. Multiple filter bags 29 are placed at the bottom of the porous filter plate 27. The filter bags 29 can further filter the wastewater that has passed through the porous filter plate 27, enhancing the effect of the initial filtration and improving the purity of the wastewater. Inclined plates 28 are fixedly connected to the inner walls on both sides of the bag filter box 8. The inclined plates 28 facilitate the transmission of wastewater, allowing the wastewater to flow more smoothly in the bag filter box 8 and avoiding water accumulation that could affect the filtration efficiency. A filtrate tank 7 is placed at the bottom of the bag filter box 8. The filtrate tank 7 is connected to the bag filter box 8 through a pipe. The pipe is equipped with a switch valve for controlling the flow of wastewater. It should be noted that all filtrate tanks mentioned later are connected to the corresponding filters through pipes, and each of these pipes is equipped with a switch valve.

[0040] The filtrate tank 7 is used to collect wastewater after preliminary filtration by the bag filter box 8. The outer wall of the filtrate tank 7 is fixedly connected to the transfer pipe 9, which can transfer the pre-filtered water in the filtrate tank 7 to ensure that the wastewater can enter the next treatment stage. The outer wall of the transfer pipe 9 is fixedly connected to the safety filter 10, which can further intercept any small impurities that may remain in the wastewater, ensuring that the wastewater entering the subsequent stage is of higher quality and avoiding damage to the subsequent equipment caused by impurities.

[0041] Reference Figures 1 to 4 At the bottom of the security filter 10, a second filtrate tank 11 is placed. The second filtrate tank 11 serves to temporarily store the wastewater treated by the security filter 10, facilitating subsequent transport operations. A third transmission pipe 12 is fixedly connected to the outer wall of the second filtrate tank 11. The third transmission pipe 12 serves as a channel for wastewater transport, ensuring that the wastewater can flow smoothly to the next treatment location. An intermediate water tank 13 is fixedly connected to the outer wall of the third transmission pipe 12. The intermediate water tank 13 can store a certain amount of wastewater, providing sufficient water for subsequent circulating filtration. A circulating pump 14 is fixedly connected to the outer wall of the intermediate water tank 13. After the circulating pump 14 is started, it can continuously reflux the internal wastewater with the ceramic membrane filter host 15 for filtration. Through this circulating filtration method, impurities in the wastewater can be removed more thoroughly, improving the purification level of the wastewater and ensuring that the wastewater can achieve better treatment results.

[0042] A filtrate tank 16 is fixedly connected to the bottom of the ceramic membrane filter host 15. The filtrate tank 16 is used to collect the wastewater after filtration by the ceramic membrane filter host 15, which is convenient for subsequent transfer and transportation. A transfer pump 17 is fixedly connected to the outer wall of the filtrate tank 16. The transfer pump 17 provides power to transfer the wastewater in the filtrate tank 16 through the pipe fixedly connected to its inner wall. The other end of the pipe is fixedly connected to the nanofiltration membrane filter host 18. The nanofiltration membrane filter host 18 can further finely filter the wastewater, remove smaller impurity particles and some dissolved harmful substances in the wastewater, and improve the quality of the wastewater. A filtrate tank 19 is placed at the bottom of the nanofiltration membrane filter host 18. The filtrate tank 19 is used to receive the wastewater after filtration by the nanofiltration membrane filter host 18, which is convenient for subsequent transportation and treatment.

[0043] A transmission pipe 20 is fixedly connected to the outer wall of the filtrate tank 419. The transmission pipe 20 serves as a channel for wastewater transmission, allowing the wastewater in the filtrate tank 419 to be transferred to the next treatment stage. The other end of the transmission pipe 20 is fixedly connected to a reverse osmosis membrane filter host 21. The reverse osmosis membrane filter host 21 can perform deep filtration on the wastewater, further removing impurities such as salt and organic matter from the wastewater, so that the treated water meets the requirements for cleaning water and can be used for repeated cleaning of parts. A filtrate tank 22 is fixedly connected to the bottom of the reverse osmosis membrane filter host 21. The filtrate tank 22 is used to collect the water filtered by the reverse osmosis membrane filter host 21 for convenient subsequent operation. A transmission pipe 25 is fixedly connected to the outer wall of the filtrate tank 22. The transmission pipe 25 can transmit the water inside the filtrate tank 22 out. A recovery tank 26 is fixedly connected to the other end of the transmission pipe 25. The recovery tank 26 is used to store the water that has been completely filtered and plays a centralized collection role. A reuse pipe 23 is fixedly connected to the outer wall of the recovery tank 26. The reuse pipe 23 can serve as a channel for the recovered cleaning water to flow to the reuse point. The reuse pipe 23 is connected to the main cleaning pipe 37. The main cleaning pipe 37 is connected to the cleaning section of the parts processing equipment 30 through a branch cleaning pipe 36. A valve 38 is provided on the branch cleaning pipe 36. A transfer pump 24 is fixedly connected to the outer wall of the reuse pipe 23. After the transfer pump 24 is started, it can transmit the water back to the reuse point through the reuse pipe 23 to realize the recycling of wastewater. When the parts processing equipment 30 is being cleaned, valve 38 is opened, and transfer pump 24 can transfer the cleaning water in the recovery tank 26 to the parts processing equipment 30 through the reuse pipe 23, main cleaning pipe 37, and branch cleaning pipe 36 for cleaning the parts.

[0044] Working principle: Vacuum pump 2 is started, and vacuum pump 2 draws the wastewater in the collection box 31 into the cleaning liquid receiving box 3 through the branch liquid flow pipe 32, the main liquid flow pipe 35, and the cleaning liquid wastewater pumping pipe 1 for preliminary treatment of the wastewater. Then the treated water is transferred to the liquid receiving box 5 through the pipeline. During the liquid transfer, the pipeline is equipped with a valve, which can be used to determine whether to transfer the pre-treated wastewater. At this time, the wastewater is transferred to the bag filter box 8 through the transfer pipe 6. The wastewater passes through the porous filter plate 27 and then through the filter bag 29 for preliminary filtration. The pre-filtered wastewater is then transferred to the inner wall of the filtrate box 7 through the pipeline. The inclined plate 28 facilitates the transfer of wastewater.

[0045] Then, the pre-filtered water from filtrate tank 17 is transferred to the interior of intermediate water tank 13 via transfer pipe 29. Intermediate water tank 13 continuously filters the wastewater between the internal wastewater and ceramic membrane filter host 15 via circulation pump 14. After complete filtration, the wastewater is transferred to the inner wall of filtrate tank 36 via pipe, and then to the inner wall of nanofiltration membrane filter host 18 via transfer pump 17. Nanofiltration membrane filter host 18 then transfers the filtered wastewater to the inner wall of filtrate tank 49 via pipe, and then filtrate tank 49 is transferred to the inner wall of reverse osmosis membrane filter host 21 via transfer pipe 420. Reverse osmosis membrane filter host 21 then transfers the wastewater to the inner wall of filtrate tank 522 via pipe. The wastewater inside filtrate tank 522 is transferred to the interior of recovery tank 26 via transfer pipe 525. Then, the water is transferred to the main cleaning pipe 37 via reuse pipe 23 via transfer pump 24, and then to the parts processing equipment 30 via branch cleaning pipe 36.

[0046] It is understood that the multiple parts processing equipment 30 of this utility model are not limited to a linear arrangement, but can also be arranged in a matrix, etc.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
