Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and more specifically, to a self-cleaning recovery device for cleaning fluid. Background Technology

[0002] A cleaning machine is a device that uses cleaning fluid to clean workpieces (such as gears), and can remove residual oil and debris from the surface of the workpiece.

[0003] When using a cleaning machine to clean workpieces, the cleaning solution used in the cleaning process will leave a large amount of metal slag after cleaning. In order to achieve the recycling of the cleaning solution, it is necessary to remove the iron filings and slag in the cleaning solution through sedimentation, filtration and other methods before it can be reused.

[0004] As disclosed in patent announcement CN205966643U, a cleaning fluid recovery structure for a workpiece cleaning equipment includes a cleaning center with a closed cleaning chamber. The bottom of the cleaning chamber has a cone-shaped cleaning fluid outlet. Directly below the outlet is a movable recovery tank for recovering the cleaning fluid. Above the recovery tank, corresponding to the outlet, is a transition trough. One end of the transition trough has a cleaning fluid collection port corresponding to the outlet. The lower side of the transition trough connects to the recovery tank, and the other end is a slag discharge end. Below the transition trough is a slag conveying assembly with a length and width matching the trough. The assembly includes a filter conveyor belt with numerous filter holes. The cleaning fluid collection port corresponds to the upper surface of the filter conveyor belt, which filters and conveys debris from the cleaning fluid to the slag discharge end. However, this structure is complex. While it achieves filtration of debris in the cleaning fluid, some debris leakage is possible, compromising the cleanliness of the cleaning fluid. Meanwhile, debris can easily clog the filter pores, affecting the filtration effect. The filter belt needs to be replaced promptly, but this process is complex, time-consuming, and labor-intensive. Furthermore, the cleaning solution contains a large amount of oil, which cannot be separated from the water during filtration, resulting in an unclean cleaning solution that affects subsequent use.

[0018] 3. The oil-absorbing film absorbs the oil in the cleaning solution. After absorption, the oil is scraped out by the scraper and placed into the oil-absorbing box, thus separating the oil in the cleaning solution and allowing the oil to be placed separately, ensuring the cleanliness of the cleaning solution and improving the yield of subsequent products.

[0019] 4. The flushing butterfly valve can change the cross-sectional area of ​​the flow channel in the inlet box, flexibly adjusting the flow rate of the cleaning fluid to adapt to different intensities of flow. Furthermore, it can limit or release the resistance to the inflow of the cleaning fluid, maintaining a stable inflow pressure and preventing pressure fluctuations from damaging the device or affecting the recovery effect.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 6 As shown, this utility model discloses a self-cleaning recovery device for cleaning fluid, including a box 1. A partition 4 is fixedly provided inside the box 1 to divide it into a left half 2 and a right half 3. The length of the partition 4 is less than the length of the box 1, so that the left half 2 and the right half 3 are connected to each other.

[0025] In this invention, a filter assembly 5 is fixedly installed inside the right half 3. Above the filter assembly 5 is an inlet box 6 fixed to and connected to the housing 1.

A flushing butterfly valve 63 is installed on the inlet pipe 61. The flushing butterfly valve 63 can change the cross-sectional area of ​​the flow channel in the inlet box 6, flexibly adjusting the flow rate of the cleaning fluid to adapt to different intensities of flow. Furthermore, it can limit or release the resistance to the inflow of the cleaning fluid, maintaining a stable inflow pressure and preventing pressure fluctuations from damaging the device or affecting the recovery effect.

[0026] Specifically, the filter assembly 5 includes at least a set of support plates 51 fixed to the top plate of the housing 1. Each support plate 51 has a filter port 52.

[0029] The above design is ingenious. The strong magnetic rod can adsorb metal impurities such as iron filings in the filter screen, so as to facilitate the collection and treatment of such metal impurities. The operation is simple and convenient, easy to disassemble, replace and maintain, greatly improving work efficiency and having a wide range of applications.
