Description

Technical Field

[0001] This utility model relates to the field of filter element technology, specifically to a microporous high-efficiency filter element that is easy to replace. Background Technology

[0002] Microporous high-efficiency filter cartridges are filter cartridge products that utilize microporous structures to achieve high-efficiency filtration. Their core principle is to trap tiny particles, bacteria, viruses, and other impurities in liquids or gases through precise microporous design. They are widely used in industries such as pharmaceuticals, food and beverages, electronics, and chemicals.

[0003] The prior art discloses a replaceable filter element (publication number CN216170900U), comprising a filter element and inner plates disposed on the upper and lower sides of the filter element. The inner plates include a first inner plate connected to the upper side of the filter element and a second inner plate connected to the lower side of the filter element. A detachable first outer plate is mounted on the first inner plate, and a detachable second outer plate is mounted on the second inner plate. The second outer plate and the first outer plate are connected by detachable support rods located on both sides of the filter element. In this invention, the filter element is fixed to the inner plates, and the inner plates can be plugged into and pulled into slots on the outer plates via buckles, allowing the filter element to be replaced during subsequent use. The frame formed by the outer plates and support rods supports the filter element, ensuring the filter element is supported within the frame.

[0004] The inner plate is connected to the filter element by hot melt adhesive. When the filter element is detached from the inner plate, it is necessary to heat the filter element and the inner plate at high temperature. High temperature heating can easily damage the filter element and the inner plate, and it takes a lot of time to repair the filter element. Utility Model Content

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A replaceable microporous high-efficiency filter element includes a microporous filter element 1 and a filter element housing 2. The left and right sides of the filter element housing 2 are threaded with connecting housings 3. The microporous filter element 1 is installed inside the filter element housing 2.

[0029] The microporous filter element 1 includes a support frame 11, a connecting frame 12, a limiting component 13, and a threaded rod 14. The support frame 11 is installed at the bottom of the limiting component 13, the connecting frame 12 is fixedly connected to the inner wall surface of the support frame 11, and the threaded rod 14 is fixedly connected to the top surface of the connecting frame 12.

[0030] The limiting component 13 includes a filtering unit and a clamping unit, which are arranged sequentially from the inside to the outside.

[0031] The filter unit includes a metal horizontal plate 131, a filter frame 132 fixedly connected to the bottom surface of the metal horizontal plate 131, and a microporous filter element body 136 inserted into the inner wall surface of the filter frame 132. A locking bolt 138 is threaded to the bottom of the metal horizontal plate 131, locking the microporous filter element body 136 and the metal horizontal plate 131 together. This secures the microporous filter element body 136 to the filter frame 132, preventing it from detaching from the metal horizontal plate 131 and the filter frame 132. The top of the filter element body 136 is threaded with a locking bolt 138. The metal horizontal plate 131 is movably connected to the top surface of the filter element housing 2. The filter frame 132 is inserted into the inner wall surface of the filter element housing 2. The microporous filter element body 136 is slidably connected to the inner wall surface of the connecting housing 3. The metal horizontal plate 131 drives the microporous filter element body 136 to move downward through the filter frame 132. The filter element housing 2 can determine the position of the metal horizontal plate 131, the filter frame 132 and the microporous filter element body 136, which facilitates the disassembly and replacement of the microporous filter element body 136.

[0032] The clamping unit includes a metal plate 133, with a silicone block 137 fixedly connected to the inner wall of the metal plate 133. The silicone block 137 is movably connected to the top surface of a metal horizontal plate 131. The metal plate 133 is slidably connected to the front and rear surfaces of the metal horizontal plate 131. The metal plate 133 and the silicone block 137 can determine the position of the metal horizontal plate 131, allowing the metal horizontal plate 131 and the filter element housing 2 to be in a sealed state. An electric push rod 134 is installed at the bottom of the metal plate 133. A limiting frame 135 is connected to the surface of the electric push rod 134. The limiting frame 135 is movably connected to the top surface of a support frame 11. The support frame 11 is movably connected to the bottom surface of the filter element housing 2. The frame 12 is movably connected to the bottom surface of the filter element housing 2. The support frame 11 and the limiting frame 135 can clamp and fix the filter element housing 2, making it easy to disassemble and replace the filter element housing 2. The limiting frame 135 is slidably connected to the surface of the filter element housing 2. The metal plate 133 is slidably connected to the surface of the filter element housing 2. The limiting frame 135 and the metal plate 133 can seal the filter element housing 2 and the metal horizontal plate 131. The threaded rod 14 is inserted into the bottom of the limiting frame 135. The limiting frame 135 is movably connected to the top surface of the connecting frame 12. The connecting frame 12 and the limiting frame 135 are locked and fixed by the threaded rod 14, thereby determining the position of the limiting frame 135.

[0033] When in use, the electric push rod 134 is activated. The piston rod inside the electric push rod 134 can push the metal plate 133 to move upward. The metal plate 133 can drive the silicone block 137 to move upward, so that the metal plate 133 moves upward along the surface of the filter element housing 2 and the connecting housing 3, so that the silicone block 137 is separated from the metal horizontal plate 131.

[0034] Then rotate the nut, which rotates on the surface of the threaded rod 14, causing the connection between the limiting frame 135 and the threaded rod 14 to loosen.

[0035] Pulling the limiting frame 135 upward, the limiting frame 135 can be driven upward by the electric push rod 134, so that the electric push rod 134 slides along the surface of the filter element housing 2, causing the limiting frame 135 to disengage from the filter element housing 2.

[0036] At this time, the metal horizontal plate 131 is pulled upward, and the metal horizontal plate 131 drives the microporous filter element body 136 to move upward through the filter frame 132, so that the filter frame 132 and the microporous filter element body 136 move upward along the inner wall surface of the filter element shell 2.

[0037] Rotating the locking bolt 138 disengages it from the metal horizontal plate 131 and the microporous filter element body 136, loosening the connection between the microporous filter element body 136 and the metal horizontal plate 131. This pushes the microporous filter element body 136 inward, allowing it to slide along the bottom surface of the metal horizontal plate 131, thus detaching it from the filter frame 132 and facilitating the disassembly and replacement of the filter frame 132.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
