[0002] Polishing liquid is an important surface treatment liquid, usually used to remove defects, oxide layers, rust, scratches and slight processing marks on the metal surface, so as to obtain a smoother and brighter surface effect. During the production and use of polishing liquid, the filtration treatment of polishing liquid is very important, because unqualified liquid may contain various impurities and particles, which may lead to problems such as poor polishing effect and equipment damage.

[0003] Usually during use, the polishing liquid will enter the first filtration tank inside the device through the polishing liquid collection tank. Under the action of the filter cotton, solid particles or impurities will be blocked on the filter cotton, and the filtered clean polishing liquid will flow out of the device. The clean polishing liquid will flow into the recovery tank or the reflux system, so that the recycling of the polishing liquid can be realized, saving resources and costs.

[0004] Considering that during long-term use, the pores in the filter cotton will be blocked by impurities, resulting in the filter cotton being unable to effectively filter solid particles or impurities, which will lead to a decrease in filtration efficiency and the inability to effectively remove impurities from the polishing liquid. Therefore, a polishing liquid filtration device is proposed to solve the above problems. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 4, an embodiment provided by the present utility model: a polishing liquid filtering device, including a base 1, the top of the base 1 is fixedly connected with a polishing liquid collection pool 2, which provides a fixed support effect for the polishing liquid collection pool 2 through the top of the base 1. The outer wall of the polishing liquid collection pool 2 is fixedly connected with a primary filtration pool 3, which provides a fixed support effect for the primary filtration pool 3 through the outer wall of the polishing liquid collection pool 2. An extrusion mechanism is arranged on the inner wall of the primary filtration pool 3. The extrusion mechanism includes a baffle 11, the bottom end of the baffle 11 is fixedly connected with the inner wall of the primary filtration pool 3, which provides a fixed support effect for the baffle 11 through the inner wall of the primary filtration pool 3. A pressing plate 5 is slidably connected to the inner wall of the primary filtration pool 3, enabling the pressing plate 5 to move horizontally along the inner wall of the primary filtration pool 3. An inclined plate A13 is fixedly connected to the outer wall of the pressing plate 5, enabling the inclined plate A13 to drive the pressing plate 5 to move together when moving horizontally.

[0032] The outer wall of the inclined plate A13 is slidably connected to the inner wall of the primary filtration pool 3, enabling the inclined plate A13 to always move horizontally along the inner wall of the primary filtration pool 3. The outer wall of the inclined plate A13 is in contact connection with an inclined plate B14, enabling the inclined plate A13 to move horizontally when the inclined surface of the inclined plate A13 is vertically extruded by the inclined surface of the inclined plate B14. The outer wall of the inclined plate B14 is elastically connected to the inner wall of the primary filtration pool 3 through a spring B17. Through the elastic force of the spring B17, the inclined plate B14 can always maintain an upward movement effect without being affected by external forces. The outer wall of the inclined plate B14 is slidably connected to the inner wall of the primary filtration pool 3, enabling the inclined plate B14 to move vertically along the inner wall of the primary filtration pool 3. A pedal 6 is fixedly connected to the outer wall of the inclined plate B14, enabling the inclined plate B14 to move vertically when the pedal 6 is stepped on. The outer wall of the pedal 6 is slidably connected to the inner wall of the primary filtration pool 3, enabling the pedal 6 to move vertically along the inner wall of the primary filtration pool 3.

[0033] Refer to Figure 3 - Figure 4 , a guide rod 15 is fixedly connected to the outer wall of the inclined plate A13, enabling the guide rod 15 to move together when the inclined plate A13 moves horizontally. The outer wall of the guide rod 15 is elastically connected to the inner wall of the primary filtration pool 3 through a spring A16. Through the elastic force of the spring A16, the guide rod 15 can always maintain an inward movement effect without being affected by external forces. The outer wall of the guide rod 15 is slidably connected to the inner wall of the primary filtration pool 3, enabling the guide rod 15 to move horizontally along the inner wall of the primary filtration pool 3.

[0034] Refer to Figure 1 - Figure 3, a plate body 4 is inserted into the inner wall of the first-stage filtration tank 3, enabling the plate body 4 to move horizontally along the inner wall of the first-stage filtration tank 3. A bolt 12 penetrates and is threadedly connected to the inner wall of the plate body 4, enabling the bolt 12 to move vertically along the inner wall of the plate body 4. The outer wall of the bolt 12 is threadedly connected to the inner wall of the first-stage filtration tank 3, enabling the bolt 12 to move vertically along the inner wall of the first-stage filtration tank 3 and simultaneously enabling the plate body 4 to be fixed to the inner wall of the first-stage filtration tank 3. The bottom end of the plate body 4 is in contact connection with a filter cotton 10, enabling the plate body 4 to block the top end of the filter cotton 10.

[0035] Refer to Figure 2 , Figure 4 , the outer wall of the filter cotton 10 is in contact connection with the outer wall of the plate body 4, and the outer wall of the filter cotton 10 is in contact connection with the outer wall of the pressing plate 5, enabling the filter cotton 10 to be located between the plate body 4 and the pressing plate 5.

[0036] Refer to Figure 1 - Figure 4 , a drainage plate 7 is fixedly connected to the outer wall of the first-stage filtration tank 3, enabling the polishing liquid filtered by the filter cotton 10 to uniformly flow into the lower second-stage filtration tank 8 through the drainage plate 7.

[0037] Refer to Figure 3 - Figure 4 , one end of a spring A16 is fixedly connected to the outer wall of the guide rod 15, and the other end of the spring A16 is fixedly connected to the inner wall of the first-stage filtration tank 3. When the inclined plate A13 stops moving outward, it can move inward through the elastic force of the spring A16, thereby driving the pressing plate 5 to reset.

[0038] Refer to Figure 3 , one end of the spring A16 is fixedly connected to the outer wall of the inclined plate B14, and the other end of the spring A16 is fixedly connected to the inner wall of the first-stage filtration tank 3. When the pedal 6 stops being stepped on, the inclined plate B14 can move upward through the elastic force of the spring, and at the same time, the inclined surface of the inclined plate A13 is no longer squeezed.

[0039] Refer to Figure 1 - Figure 2 , the top end of a base 1 is fixedly connected to a second-stage filtration tank 8, providing a fixed support effect for the second-stage filtration tank 8 through the top end of the base 1, enabling the polishing liquid filtered from the first-stage filtration tank 3 to flow into the second-stage filtration tank 8 along the drainage plate 7 for secondary filtration. The outer wall of the second-stage filtration tank 8 is fixedly connected to a recovery tank 9, providing a fixed support effect for the recovery tank 9 through the outer wall of the second-stage filtration tank 8, enabling the polishing liquid filtered by the second-stage filtration tank 8 to flow into the recovery tank 9 and recycling the finally filtered polishing liquid through an electric pump.

[0040] Working principle: The polishing liquid first enters the polishing liquid collection pool 2. Then, when the polishing liquid reaches a certain liquid level, the upper-layer polishing liquid will flow into the primary filtration pool 3, and then is primarily filtered by the filter cotton 10. Then it flows along the drainage plate 7 into the secondary filtration pool 8 for secondary filtration. Then, when the polishing liquid reaches a certain liquid level, it flows into the recovery pool 9 and is recycled by the electric pump.

[0041] When the inside of the filter cotton 10 is blocked by impurities, the pedal 6 can be stepped on to drive the inclined plate B14 to move vertically. Then the inclined surface of the inclined plate B14 squeezes the inclined surface of the inclined plate A13, thereby driving the extrusion pair to squeeze the filter cotton 10, so that the impurities in the filter cotton 10 are extruded. When the pedal 6 is released, the inclined plate B14 will move upward due to the elastic force of the spring B17, and at the same time relieve the extrusion of the inclined surface of the inclined plate A13, so that the inclined plate A13 can move inward due to the elastic force of the spring A16, thereby driving the extrusion plate 5 to reset and stop squeezing the filter cotton 10.

[0042] When the filter cotton 10 needs to be replaced, first rotate the bolt 12 to release the fixation of the plate body 4. Then pull out the plate body 4 outward so that it no longer blocks the filter cotton 10. Then take out the filter cotton 10 upward. Then replace it with a new filter cotton 10. Then insert the plate body 4 into the inner wall of the primary filtration pool 3, and then rotate the bolt 12 to fix the plate body 4.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
