Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a detachable UPE filter element. Background Technology

[0002] UPE filter cartridges are typically installed inside a filter housing for fine filtration of liquids or gases. Their pleated structure helps improve filtration efficiency, and this can be achieved by adjusting the density of the pleats and the material of the filter paper to meet different filtration precision requirements. Tubular PTFE or UPE filter cartridges are tubular in shape and usually have certain length and inner diameter specifications. They can be directly installed in piping systems for online filtration of fluids.

[0003] A search of existing technology revealed a device called "A Long Tube Sintered Filter Cartridge" (publication number CN213555688U). This device uses a first disc, a second disc, and a third disc evenly located inside a first hollow cylinder. The surface of the first disc has multiple second circular holes evenly distributed, the surface of the second disc has multiple pentagonal holes evenly distributed, and the surface of the third disc has multiple rectangular holes evenly distributed. This design fixes the structure of the long tube sintered filter cartridge, facilitating adaptive stratified filtration of objects of different densities. However, the filter cartridge needs to be frequently disassembled for cleaning, usually by prying open the cover. Currently, the filter cartridge cover is welded and cannot be disassembled, making the cleaning operation complex and affecting work efficiency. Utility Model Content

[0004] Therefore, it is necessary to address the issue that filter elements need to be frequently disassembled for cleaning, which is usually done by prying open the cover. However, current filter element covers are welded and cannot be disassembled, making the cleaning process complicated and affecting work efficiency. To address this, a removable UPE filter element is provided, comprising: an outer housing, on the inner wall of which an internal filter element is installed; and a connecting mechanism, mounted on the surface of the outer housing, extending to the lower end of the outer housing. The connecting mechanism includes a sealing component fixedly connected to the surface of the outer housing, with a disassembly component connected to its inner side. The surface of the disassembly component extends to the lower end of the outer housing, and an assembly component is fitted over the disassembly component. The inner wall of the assembly component is connected to the surface of the sealing component.

[0005] In one embodiment, the sealing assembly includes a fixing frame fixedly connected to the lower end of the surface of the outer housing. A threaded ring is fixedly connected to the surface of the fixing frame away from the outer housing. The inner side of the fixing frame and the surface of the threaded ring combine to form an inner cavity. Multiple annular grooves are formed on the inner wall of the threaded ring and the inner side of the inner cavity. The annular grooves communicate with the inner cavity. The multiple annular grooves are evenly distributed longitudinally.

[0006] In one embodiment, the disassembly assembly includes a ring disposed inside the inner cavity. A connecting sleeve is fixedly connected to the lower end of the ring. A rotating groove is formed at the lower end of the connecting sleeve. A rotating seat is connected to the inner wall of the rotating groove. A thrust bearing is fitted onto the surface of the rotating seat. The upper end of the thrust bearing contacts the lower end of the connecting sleeve, and the lower end of the thrust bearing contacts the inner bottom wall of the rotating seat. The ring facilitates disassembly. Inserted into the inner cavity, the ring and the inner cavity cooperate to form a U-shaped flow channel, reducing the possibility of liquid leakage.

[0007] In one embodiment, the assembly includes an outer sleeve fitted over the outside of the connecting sleeve, the upper end of which is fixedly connected to a threaded sleeve, and the inner wall of the threaded sleeve is threadedly connected to the surface of a threaded ring.

[0008] In one embodiment, a plurality of abutment blocks are fixedly connected to the surface of the connecting sleeve, and the plurality of abutment blocks are evenly distributed in a ring shape along the surface of the connecting sleeve. The two sets of abutment blocks are centrally symmetrically distributed about the rotation axis of the rotating seat, so that abutment blocks of the same height can be used with tools to separate from the sealing assembly, ensuring convenience during disassembly.

[0009] In one embodiment, a plurality of rubber rings are fixedly connected to the surface of the annulus, and the plurality of rubber rings match adjacent annular grooves. The plurality of annular grooves and the rubber rings on the surface of the annulus cooperate to form a multi-layer sealing structure, reducing the occurrence of liquid leakage.

[0010] In one embodiment, an abutment frame is fixedly connected to the inner wall of the outer sleeve, and the inner bottom wall of the abutment frame contacts the lower end of the rotating seat. The sealing connection is completed by the connecting sleeve driving the ring to insert into the inner cavity.

[0011] Beneficial effects

[0012] The aforementioned detachable UPE filter element, through its sealing and disassembly components, can achieve a good sealing effect during use. The circular ring and the inner cavity cooperate to form a Z-shaped flow channel, and multiple ring grooves cooperate with the rubber ring on the surface of the circular ring to form a multi-layer sealing structure. When disassembly is required, tools are used to press against the abutment blocks of the same height, which improves the convenience of disassembly operations, simplifies the cleaning operation steps, and ensures work efficiency.

[0013] By coordinating the assembly and disassembly components, the screw sleeve can be rotated by the outer sleeve of the knob under the combined action of the assembly and disassembly components. The screw sleeve, in conjunction with the screw ring, gradually moves the contact frame upward. As the contact frame moves upward, the contact rotating seat moves upward synchronously, allowing the ring to be inserted into the inner cavity, thus improving the convenience of assembly and mating.

[0026] The following is combined Figures 1-4 This invention describes a detachable UPE filter element.

[0027] In one embodiment, a removable UPE filter element includes: an outer housing 1, an inner filter element 2 mounted on the inner wall of the outer housing 1; and a connecting mechanism 3 mounted on the surface of the outer housing 1, the surface of the connecting mechanism 3 extending to the lower end of the outer housing 1; wherein the connecting mechanism 3 includes a sealing component 31 fixedly connected to the surface of the outer housing 1, a disassembly component 32 connected to the inner side of the sealing component 31, the surface of the disassembly component 32 extending to the lower end of the outer housing 1, and an assembly component 33 sleeved on the outside of the disassembly component 32, the inner wall of the assembly component 33 being connected to the surface of the sealing component 31;

[0028] It should be noted that in chemical raw material transportation pipelines, tubular UPE filter elements can intercept solid particles and prevent these particles from entering subsequent production equipment, thereby protecting the normal operation of the equipment. Tubular filter elements generally have high strength and can withstand a certain pressure, making them suitable for fluid filtration applications with large flow rates and high pressures.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the sealing assembly 31 includes a fixing frame 311 fixedly connected to the lower end of the surface of the outer housing 1. A threaded ring 312 is fixedly connected to the surface of the fixing frame 311 away from the outer housing 1. The inner side of the fixing frame 311 and the surface of the threaded ring 312 combine to form an inner cavity 313. Multiple annular grooves 314 are provided on the inner wall of the threaded ring 312 and the inner side of the inner cavity 313. The annular grooves 314 communicate with the inner cavity 313. The multiple annular grooves 314 are evenly distributed longitudinally.

[0030] The disassembly assembly 32 includes a ring 321 disposed inside the inner cavity 313. A connecting sleeve 322 is fixedly connected to the lower end of the ring 321. A rotating groove 325 is opened at the lower end of the connecting sleeve 322. A rotating seat 323 is connected to the inner wall of the rotating groove 325. A thrust bearing 324 is sleeved on the surface of the rotating seat 323. The upper end of the thrust bearing 324 contacts the lower end of the connecting sleeve 322. The lower end of the thrust bearing 324 contacts the inner bottom wall of the rotating seat 323. A plurality of abutment blocks 326 are fixedly connected to the surface of the connecting sleeve 322. The plurality of abutment blocks 326 are evenly distributed in a ring shape along the surface of the connecting sleeve 322. A plurality of rubber rings 327 are fixedly connected to the surface of the ring 321. The plurality of rubber rings 327 match the adjacent ring grooves 314.

[0031] In this embodiment, the ring 321 facilitates disassembly. The ring 321 is inserted into the inner cavity 313. With the cooperation of the ring 321 and the inner cavity 313, a U-shaped flow channel is formed, which reduces the occurrence of liquid leakage. Furthermore, the multiple ring grooves 314 cooperate with the rubber rings 327 on the surface of the ring 321 to form a multi-layer sealing structure, which further reduces the occurrence of liquid leakage and ensures the sealing of the water flow during use.

[0032] When disassembly is required, the contact blocks 326 can be pressed with a tool. There are two sets of contact blocks 326, with four contact blocks 326 in each set. The horizontal height of the upper end of each set of contact blocks 326 gradually decreases. The two sets of contact blocks 326 are centrally symmetrical about the rotation axis of the rotating seat 323, so that the contact blocks 326 of the same height can be pressed with a tool to separate them from the sealing component 31, ensuring the convenience of the disassembly process.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the assembly component 33 includes an outer sleeve 332 sleeved outside the connecting sleeve 322. A threaded sleeve 331 is fixedly connected to the upper end of the outer sleeve 332. The inner wall of the threaded sleeve 331 is threadedly connected to the surface of the threaded ring 312. An abutment 333 is fixedly connected to the inner wall of the outer sleeve 332. The inner bottom wall of the abutment 333 contacts the lower end of the rotating seat 323.

[0034] In this embodiment, during assembly, the outer sleeve 332 of the knob can drive the threaded sleeve 331 to rotate. The threaded sleeve 331, in conjunction with the threaded ring 312, gradually drives the abutment frame 333 to move upward. When the abutment frame 333 moves upward, the abutment rotating seat 323 moves upward synchronously. The connecting sleeve 322 drives the ring 321 to be inserted into the inner cavity 313 to complete the sealing connection operation.

[0035] Working principle: Disassembly is facilitated by the ring 321, which is inserted into the inner cavity 313. The ring 321 and the inner cavity 313 cooperate to form a Z-shaped flow channel. Multiple annular grooves 314 cooperate with the rubber ring 327 on the surface of the ring 321 to form a multi-layer sealing structure. During disassembly, the abutment block 326 is pressed with a tool. The two sets of abutment blocks 326 are centrally symmetrically distributed around the rotation axis of the rotating seat 323. The abutment blocks 326 of the same height can be separated from the sealing component 31 by pressing with a tool. During assembly, the outer sleeve 332 of the knob drives the threaded sleeve 331 to rotate. The threaded sleeve 331, together with the threaded ring 312, gradually drives the abutment frame 333 to move upward. When the abutment frame 333 moves upward, the abutment rotating seat 323 moves upward synchronously. The ring 321 is inserted into the inner cavity 313 through the connecting sleeve 322 to complete the sealing connection operation.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
