[0002] Marble originally refers to the white limestone with black patterns produced in Dali, Yunnan Province. Later, it gradually developed into a name for all limestones with various colors and patterns used as building decoration materials. Marble polishing refers to the solution to the pollution, weathering, holes, dullness and other phenomena produced by marble decorative stones laid on marble floors, walls, countertops, columns, etc., which is to use chemicals, machinery, tools, etc. to clean and polish the marble surface to restore the brightness of the marble slab to the same level as before the initial installation and to make it more ornamental.

[0003] Chinese patent publication number CN205672635U discloses a wastewater recovery and filtering device for marble polishing and grinding, comprising a wastewater collecting barrel, a filtering device, a clean water collecting device and a grinding powder collecting device, wherein the wastewater collecting barrel is located above the filtering device and is fixedly connected thereto, the filtering device is located above the clean water collecting device and is fixedly connected thereto, and the grinding powder collecting device is located at the side of the filtering device and is fixedly connected thereto. Although the device can realize automatic filtration of wastewater, has high filtration efficiency and saves manpower, and also provides a second filter layer at the lower end of the first filter layer to ensure that the wastewater is filtered cleanly, and finally, by providing a negative pressure filter layer, it can ensure that the water flowing into the clean water collecting device is fully filtered, and negative pressure filtration can prevent the grinding powder from clogging the filter holes, and the filtration efficiency is high, but it is inevitable that marble residues remain on the surface of the screen during filtration. When the equipment is used for a long time, the marble residues may cause the screen to be blocked at the least or the screen to be damaged at the most, thereby affecting its filtration effect, so it needs to be improved.

[0027] See also Figure 2-4 A fixed plate 9 is rotatably connected to the surface of the rotating shaft 8. The material of the fixed plate 9 is martensitic stainless steel. The martensitic stainless steel contains iron and can be adsorbed by the magnet 14, so that the fixed plate 9 can be fixed inside the groove 7 through the magnet 14. A long block 10 is fixedly installed on the side of the filter box 1. A latch 11 penetrates the surface of the long block 10. A tension spring 12 is sleeved on the surface of the latch 11. One end of the tension spring 12 is fixedly connected to the surface of the long block 10, and the other end of the tension spring 12 is fixedly connected to the surface of the pull plate 13, so that the tension spring 12 can drive the pull plate 13 to automatically reset. The pull plate 13 is fixedly installed on one end of the latch 11.

[0028] Embodiment 2

[0029] See also Figure 5-6 A pull ring 16 is fixedly installed on the side of the filter screen 6, and a convex particle 17 is fixedly installed on the surface of the pull ring 16, which is convenient for removing the filter screen 6 from the side of the filter box 1. The material of the convex particle 17 is natural rubber. Natural rubber is non-slip and soft, which can increase the friction between the hand and the pull ring 16. The convex particles 17 are distributed in a circular array on the surface of the pull ring 16.

[0030] Working principle: During filtration, pour the waste liquid from marble polishing and grinding from the feed port 2. After the waste liquid enters the feed port 2, it moves downward due to gravity and passes through the filter screen 6. The residue in the waste liquid is intercepted on the top surface of the filter screen 6, and then the waste liquid continues to move downward from the filter screen 6 until it is discharged from the discharge port 3. At this time, the waste liquid from marble polishing and grinding can be filtered. When the filter screen 6 needs to be replaced, manually pull the pull plate 13, and the pull plate 13 drives the latch 11 to move outward. Since the surface of the pull plate 13 is connected to the tension spring 12, the pull plate 13 also drives the tension spring 12 moves outward until the latch 11 is disengaged from the fixing plate 9, and then the fixing plate 9 is rotated. The fixing plate 9 rotates on the surface of the rotating shaft 8 and makes the fixing plate 9 stick to the magnet 14 in the groove 7. Since the fixing plate 9 is made of duplex stainless steel, the fixing plate 9 is immediately fixed on the surface of the magnet 14, and then the filter screen 6 is pulled to the other side of the filter box 1. The filter screen 6 moves in the through groove 4 and drives the slider 15 to slide inside the slide groove 5 until the filter screen 6 is taken out from one side of the filter box 1. At this time, a new filter screen 6 is taken out, so that the slide on the side of the filter screen 6 The block 15 is opposite to the slide slot 5, and then the filter screen 6 is pushed into the through slot 4, and the filter screen 6 drives the slider 15 to move into the slide slot 5 until the slider 15 moves to the other end of the slide slot 5. At this time, the filter screen 6 extends from the other side of the filter box 1, and then the fixing plate 9 is manually rotated, and the fixing plate 9 rotates on the surface of the rotating shaft 8 until the fixing plate 9 is separated from the surface of the magnet 14. At this time, the pull plate 13 is pulled, and the pull plate 13 drives the latch 11 to move outward. At the same time, the pull plate 13 pulls the tension spring 12 outward, so that the fixing hole on the surface of the fixing plate 9 is opposite to the latch 11, and then the pull plate 1 is pulled. 3 is released, at this time the tension spring 12 loses the external force, and due to its own tension, the pull plate 13 moves inward, and at the same time the pull plate 13 drives the latch 11 to move inward, until the latch 11 penetrates the fixed plate 9, at this time the fixed plate 9 can be fixed to the side of the filter box 1, and the filter 6 is immediately fixed inside the filter box 1. When taking out the filter 6, the pull ring 16 is manually pulled, and then the pull ring 16 is pulled outward to take out the filter 6. The pull ring 16 is arranged on the side of the filter 6, which is convenient for pulling the filter 6 from the other end, thereby improving the replacement efficiency of the filter 6 to a certain extent.
