[0013] 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.

[0014] Please see Figures 1-6 In this embodiment of the present invention, a ceramic filter that is easy to clean includes a slurry tank 1. Multiple sets of ceramic filters 2 are rotatably installed inside the slurry tank 1. A slag discharge box 3 extending into the inner cavity of the slurry tank 1 is integrally formed on the outer circumference of the slurry tank 1. The end of the slag discharge box 3 located outside the slurry tank 1 has an open structure. A guide pressing mechanism is installed on the inner wall of the slag discharge box 3 along the length direction of the slurry tank 1. A sliding seat 4 is slidably installed on the outer wall of the guide pressing mechanism. A limiting mechanism is installed inside the sliding seat 4. The limiting mechanism is used to limit the scraper 5 inserted into the inner wall of the top of the sliding seat 4.

[0015] In this embodiment: First, under the drive of the driving device (such as a motor), multiple ceramic filters 2 are driven to rotate. During the rotation process, the ceramic filters 2 are attracted by the suction of the negative pressure device, adsorbing the particulate matter in the slurry onto the microporous ceramic plates of the ceramic filters 2. At this time, the water carried in the particulate matter is drawn out, leaving only the particulate matter adsorbed on the microporous ceramic filter plates. Then, as the ceramic filters 2 rotate, the ceramic filters 2 drive the microporous ceramic plates to contact the blade of the scraper 5. The scraper scrapes off the impurities attached to the surface of the microporous ceramic plates and they fall into the interior of the slag discharge box 3, achieving the purpose of solid-liquid separation. When the scraper 5 needs to be cleaned after prolonged use to remove impurities from its surface, the scraper 5 can be axially pulled out by pressing down the limiting mechanism to release the limiting mechanism. After the scraper 5 is cleaned, the sliding seat 4 is pushed along the guide pressing mechanism, and then the scraper 5 is inserted into the inner wall of its top end and locked with the limiting mechanism again. Then the force applied to the sliding seat 4 can be removed. At this time, the guide pressing mechanism pushes the sliding seat 4 to reset and causes the blade of the scraper 5 to contact the surface of the microporous ceramic sheet, thus completing the installation. It should be noted that the end of the scraper 5 near the compression spring 11 has a guide surface, and the scraped impurities fall down along the guide surface.

[0016] Please refer to this carefully. Figure 3 , Figure 4 , Figure 5 and Figure 6The guiding and pressing mechanism includes an inner guide rod 6 and an outer guide rod 7 extending along the length of the slurry tank 1. A sliding seat 4 is slidably connected to the outer wall of the inner guide rod 6 and the outer guide rod 7. A compression spring 11 is fixedly installed between the inner wall of the slag discharge box 3 and one end face of the sliding seat 4. Two compression springs 11 are respectively sleeved on the outer periphery of the inner guide rod 6 and the outer guide rod 7. One end of the outer wall of the outer guide rod 7 is formed with an external thread. A limit nut 8 is connected to the external thread. A fixing ring 12 is fixedly connected to the middle section of the outer wall of the limit nut 8. A bellows 13 is fixedly connected between one end of the fixing ring 12 and the sliding seat 4. The bellows 13 is used to protect a part of the external thread.

[0017] In this embodiment: when it is necessary to adjust the distance or extrusion pressure between the blade of the scraper 5 and the microporous ceramic sheet, a wrench is used to connect with the limiting nut 8, and the limiting nut 8 is rotated by the wrench. At this time, the limiting nut 8 can move towards the compression spring 11 or away from the compression spring 11. When it moves toward the compression spring 11, the limiting nut 8 pushes the sliding seat 4 to move, thereby reducing the extrusion force between the scraper 5 and the microporous ceramic sheet; When it moves away from the compression spring 11, the limit nut 8 does not compress or push the sliding seat 4. At this time, the compression spring 11 resets and pushes the sliding seat 4. The sliding seat 4 drives the scraper 5 to move towards the microporous ceramic sheet to increase the compressive force between the scraper 5 and the microporous ceramic sheet. During the above process, when the limit nut 8 is rotated, the sliding seat 4 moves and drives the end connected to the bellows 13 to move synchronously. During this process, the bellows 13 expands or contracts, always protecting the external thread and preventing scraped impurities from contacting the external thread.

[0018] Please refer to this carefully. Figure 6 The limiting mechanism includes a slide groove 9 inside the slide seat 4, a slide plate 10 is slidably installed inside the slide groove 9, a limiting block 14 is fixedly installed at one end of the slide plate 10 inside the slide seat 4 and is slidably connected to the slide groove 9, a return spring 15 is fixedly connected between the bottom end of the inner wall of the slide groove 9 and the bottom end of the limiting block 14, the other end of the slide plate 10 extends to the outside of the slide seat 4, the top end of the limiting block 14 is integrally formed with a pressure inclined surface 16, and the bottom end of the scraper 5 is provided with a limiting groove 17 for the pressure inclined surface 16 to be inserted.

[0019] In this embodiment: when it is necessary to disassemble the scraper 5 for cleaning, by pressing down one end of the sliding plate 10, the sliding plate 10 drives the limiting block 14 to move downward in sync. At this time, the reset spring 15 is compressed until the limiting block 14 is completely separated from the limiting groove 17. At this time, the scraper 5 can be pulled to realize the movement and disassembly of the scraper 5. After cleaning the scraper 5, reinsert the scraper 5 into the inner wall of the top of the sliding seat 4 and push the scraper 5 to move. When the scraper 5 comes into contact with the pressure inclined surface 16, the limiting block 14 moves downward and retracts into the sliding groove 9 until the limiting groove 17 and the limiting block 14 are aligned in the vertical direction. At this time, the reset spring 15 pushes the limiting block 14 into the limiting groove 17. At this time, one end of the scraper 5 comes into contact with the closed end of the slag discharge box 3, thus achieving the installation limitation of the scraper 5.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
