[0002] Sintered filter cartridges are a commonly used filter material applied in various industries, offering excellent filtration performance and long service life. The raw materials for sintered filter cartridges are mainly powdered metal materials and organic binders, with the metal materials including stainless steel, iron, copper, etc. Their main function is to filter liquids and gases in industrial production, ensuring the safety and stability of the production process.

[0003] Existing metal powder filter elements are connected to sintered pipes, but this connection is relatively unstable, and the pipes and filter elements can easily detach. Current technology manufactures the pipes and filter element housings as detachable structures. For example, patent document CN 212941730 U discloses a sintered metal powder filter element that effectively improves the stability of the connection between the filter element housing and the sintered pipe through the design of the filter element housing, pipe, sealing pipe, screw, L-shaped clamp, pin hole, fastening nut, limiting block, and U-shaped groove, thus significantly improving the convenience of filter element replacement.

[0004] However, the above technical solutions have certain shortcomings. The fixing of the pipe and the filter element requires the use of screws and nuts, and a wrench is needed to loosen the screws and nuts. This makes it time-consuming to assemble and disassemble the pipe and the filter element, and the time may be extended due to stripped or rusted screws. This makes it difficult to replace damaged sintered filter elements later. Therefore, a high-efficiency metal powder sintered filter element device is proposed. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a high-efficiency metal powder sintered filter element device to solve the technical problem mentioned in the background of the long time required for disassembling and assembling damaged sintered filter elements.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A high-efficiency metal powder sintered filter element device, such as Figures 1 to 6 As shown, the filter cartridge 100 is equipped with end sleeves 110 at both the upper and lower ends. The top of the filter cartridge 100 is equipped with a sealing cap 130 that locks with the end sleeve 110, and the bottom of the filter cartridge 100 is equipped with a chassis 120 that is threadedly connected to the end sleeve 110.

[0027] The top of the end sleeve 110 is provided with two sets of blind holes 112. A driven seat 160 is slidably provided in the blind hole 112. A spring 161 is fixed to the bottom of the driven seat 160 and the inner end face of the blind hole 112. A positioning rod 131 extending into the blind hole 112 is fixed to the bottom of the sealing cover 130. A ball head 132 that contacts the top of the driven seat 160 is fixed to the bottom of the positioning rod 131. An arc groove 113 communicating with the blind hole 112 is provided on the top of the end sleeve 110. A spherical arc groove 114 communicating with the bottom of the arc groove 113 is provided on the curved outer wall of the blind hole 112.

[0028] A positioning ring 115 is fixed to the inner wall of the blind hole 112, and a channel for the spring 161 to pass through is reserved in the positioning ring 115;

[0029] Four sets of scraper strips 150 are movably installed inside the filter cartridge 100. Each set of scraper strips 150 is fixed to the top of the chassis 120. The four sets of scraper strips 150 are distributed in a ring array and are in contact with the inner wall of the filter cartridge 100.

[0030] An active ring 170 is movably sleeved on the outer wall of the end sleeve 110. The inner wall of the active ring 170 is provided with a connecting arm 171 fixed to the curved outer wall of each group of driven seats 160. A clearance groove 116 is provided in the inner opening of the chassis 120 at the contact position with the connecting arm 171.

[0031] When disassembling the filter cartridge 100, a vertical downward force needs to be applied to the outer wall of the active ring 170. The driven seat 160 is driven to move downward in the blind hole 112 via the connecting arm 171. When the bottom of the driven seat 160 contacts the top of the positioning ring 115, the active ring 170 can no longer move downward. At this time, the top of the driven seat 160 is flush with the lowest point of the ball head 132. At this time, a rotational force can be applied to the sealing cover 130. The positioning rod 131 at its bottom approaches the blind hole 112 in the arc groove 113 until it enters. The ball head 132 at its bottom will also move in an arc trajectory and be located at the top of the driven seat 160. At this time, the sealing cover 130 can be pulled upward to separate from the end sleeve 110. In this way, the filter cartridge 100 and the pipe 140 can be easily disassembled, making it easier to replace damaged parts.

[0032] When the filter cartridge 100 is filtering, some particles will adhere to its inner wall. At this time, the base 120 can be manually rotated to separate from the filter cartridge 100, and the scraper 150 at the top will rotate along the inner wall of the filter cartridge 100 to scrape off the particles. The particles will eventually fall to the top of the base 120. The cleaning of the inner wall of the filter cartridge 100 can be completed when the base 120 is removed.

[0033] Please refer to this carefully. Figure 4 and Figure 5 Both sets of end sleeves 110 have an inner liner ring 111 fixed on their end faces, extending into the filter cartridge 100. The curved outer wall of the inner liner ring 111 has a convex ring.

[0034] The convex ring increases the friction coefficient of the outer wall of the inner liner ring 111, resulting in a larger connection force between the filter cartridge 100 and the inner liner ring 111. After the end sleeve 110 and the filter cartridge 100 are integrally cast, the connection between the two is tight and firm.

[0035] Please refer to this carefully. Figure 1 and Figure 2 A pipe 140 is connected to the top center of the sealing cap 130, and a nut is threaded onto the outer wall of the pipe 140.

[0036] The filter cartridge 100 can be fixed on the positioning plate to achieve the final air or liquid filtration effect.

[0037] Please refer to this carefully. Figure 1 and Figure 6An annular groove is provided at the contact position between the outer wall of the end sleeve 110 and the active ring 170, and the annular groove allows the active ring 170 to drive the driven seat 160 to lower to the lowest point.

[0038] This limits the lifting and lowering stroke of the active ring 170 outside the end sleeve 110, allowing the driven seat 160 to be lowered to release the obstruction of the positioning rod 131, and making it easy to disassemble the sealing cover 130 for replacement.

[0039] When using the filter cartridge 100, a vertical downward force needs to be applied to the outer wall of the active ring 170. The driven seat 160 is driven to move downward in the blind hole 112 via the connecting arm 171. When the bottom of the driven seat 160 contacts the top of the positioning ring 115, the active ring 170 can no longer move downward. At this time, the top of the driven seat 160 is flush with the lowest point of the ball head 132. At this time, a rotational force can be applied to the sealing cover 130. The positioning rod 131 at its bottom moves closer to the blind hole 112 in the arc groove 113 until it enters. The ball head 132 at its bottom will also move in an arc trajectory and be located at the top of the driven seat 160. At this time, the sealing cover 130 can be pulled upward to separate from the end sleeve 110. In this way, the filter cartridge 100 and the pipe 140 can be easily separated, making it easier to replace damaged parts. The parts not mentioned in this device are the same as or can be implemented using existing technology.

[0040] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
