Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic filtration technology, specifically a porous ceramic filtration device. Background Technology
[0002] Porous ceramic materials are made primarily from high-quality raw materials such as corundum sand, silicon carbide, and cordierite. They are prepared through molding and a special high-temperature sintering process, resulting in porous ceramic materials with open pore sizes and high open porosity. These materials possess advantages such as high temperature and pressure resistance, resistance to acid, alkali, and organic media corrosion, good bioinertness, controllable pore structure, high open porosity, long service life, and good product regeneration performance. They are suitable for precision filtration and separation of various media, high-pressure gas exhaust silencing, gas distribution, and electrolytic membranes. However, conventional ceramic filtration devices can only use ceramic filter elements of a fixed size, making it impossible to replace them with ceramic filters of different diameters according to actual usage needs. Furthermore, filter element replacement is complex and inconvenient. Utility Model Content

[0019] 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.
[0020] Please see Figure 1-3 This utility model provides a porous ceramic filter device, including an outer cylinder 1. An mounting side frame 12 is installed on the outer wall of the outer cylinder 1. A drain pipe 11 is installed at the bottom of the outer cylinder 1. A top cover 13 is installed on the top of the outer cylinder 1 by threads. A water injection pipe 14 is installed on the top of the top cover 13. A partition 2 is installed on the inner side of the top cover 13. A top sealing cover 3 is installed at the bottom of the partition 2. A support ring frame 31 for strengthening the stability of the top sealing cover 3 is installed on the outer side of the top sealing cover 3. A filter ceramic cylinder 4 for filtration is arranged below the top sealing cover 3. A support positioning device for supporting and sealing the bottom end of the filter ceramic cylinder 4 is arranged at the bottom of the filter ceramic cylinder 4.
[0021] Furthermore, the support and positioning device includes an elastic support frame 5, an annular mounting base 51, a bottom sealing cover 52, an auxiliary positioning rod 53, an elastic bracket 54, and a support ball 55. The elastic support frame 5 is installed on the bottom inner wall of the outer cylinder 1, the annular mounting base 51 is installed on the top of the elastic support frame 5, the bottom sealing cover 52 is installed on the top of the annular mounting base 51, the bottom end of the filter ceramic cylinder 4 is snapped into the top of the bottom sealing cover 52, the auxiliary positioning rod 53 is installed on the top of the annular mounting base 51 and located inside the bottom sealing cover 52, the elastic bracket 54 is installed on the top of the auxiliary positioning rod 53, the support ball 55 is installed on the end of the elastic bracket 54, and the support ball 55 contacts the inner wall of the filter ceramic cylinder 4. The inner walls of the bottom sealing cover 52 and the top sealing cover 3 are both provided with rubber gaskets for auxiliary sealing.
[0022] Furthermore, the bottom of the top sealing cover 3 and the top of the bottom sealing cover 52 are both horn-shaped. The horn-shaped design can be used to fix filter ceramic cylinders 4 with different diameters, and the horn-shaped design facilitates docking and engagement, making installation easier.
[0023] Furthermore, the elastic support 54 is made of spring steel sheet. The elastic support 54 is horizontal when stationary. When the filter ceramic cylinder 4 is sleeved on the outside of the elastic support 54, the support ball 55 at the end of the elastic support 54 contacts the inner wall of the filter ceramic cylinder 4. The filter ceramic cylinder 4 presses the elastic support 54 downward and bends it. The filter ceramic cylinder 4 is held outside the auxiliary positioning rod 53 by the support of the elastic support 54 and the support ball 55.
[0024] Furthermore, the support ball 55 is made of rubber, which improves the protection of the filter ceramic cylinder 4 and can also play an auxiliary buffering role.
[0025] Furthermore, a positioning pin 15 for insertion and positioning is installed at the bottom of the top cover 13, and an insertion hole for insertion is opened at the top of the outer cylinder 1. A threaded ring for connection is installed on the outer side of the bottom of the top cover 13. The top cover 13 and the outer cylinder 1 are connected and installed through the threaded ring. The installation angle between the top cover 13 and the outer cylinder 1 is limited by the cooperation between the positioning pin 15 and the insertion hole, so that the top sealing cover 3 and the bottom sealing cover 52 are in the same vertical axis position.
[0026] In use, connect the sewage pipe to be purified to the water injection pipe 14. The sewage is discharged into the top cover 13 through the water injection pipe 14, and then flows down the top sealing cover 3 into the filter ceramic cylinder 4. The sewage is filtered by the filter ceramic cylinder 4. The filtered water flows down through the filter ceramic cylinder 4 and is finally discharged down through the drain pipe 11. When replacing the filter ceramic cylinder 4 with a different size, rotate the threaded ring at the bottom of the top cover 13 to disassemble the top cover 13 and the outer cylinder 1, take out the filter ceramic cylinder 4 and replace it. The new filter ceramic cylinder 4, which is fitted outside the auxiliary positioning rod 53, is kept vertical under the support of the elastic bracket 54 and the support ball 55. Then, control the top cover 13 to move to Above the outer cylinder 1, the top sealing cover 3 is positioned directly above the top of the filter ceramic cylinder 4. Then, the top cover 13 is installed to the outer cylinder 1 using a threaded ring. During installation, the bottom of the top sealing cover 3 presses against the top of the filter ceramic cylinder 4. The flared design allows the filter ceramic cylinder 4 to move closer to the center and align, so that the top of the filter ceramic cylinder 4 fits against the bottom inner wall of the top sealing cover 3, and the bottom of the filter ceramic cylinder 4 fits against the top inner wall of the bottom sealing cover 52. At the same time, it will also press the elastic support frame 5 downward to retract and adapt to the installation of filter ceramic cylinders 4 of different lengths. The elastic support frame 5 can also prevent the filter ceramic cylinder 4 from being damaged due to excessive pressure during installation. The replacement operation is simple and easy to use.
