Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure filters, in particular to a high-pressure filter which is convenient for replacing filter membranes. Background Art

[0002] Silicone oil modified materials play an important role in modern industry, especially in the manufacture of high-performance coatings, adhesives and sealing materials. In the production process of silicone oil modified semi-finished materials, high-pressure filters are used to ensure that unreacted monomers, catalyst residues and other suspended particles generated in the reaction can be effectively removed under complex chemical reactions and high temperature and high pressure conditions;

[0003] As shown in the reference case "A high-pressure filter that is easy to maintain" announcement number "CN212283164U", it is connected and fixed by bolts and threads, which is convenient for disassembly and assembly. At the same time, the sealing of the product is ensured by the matching structure of the sealing ring, bolts and threads. The matching structure of the upper end cover and the lower end cover and the high-pressure filter element ensures the convenience of filter element assembly and the sealing of the high-pressure filter element;

[0004] To facilitate replacement of high-pressure filter elements, existing filters also feature quick disassembly, making filter elements easy to insert and remove. However, if the filter element is not properly positioned after installation, it may cause the filter element to shift or vibrate in a high-pressure operating environment, which will not only affect the efficiency of the filter, but may also accelerate material wear.

[0005] Therefore, a high pressure filter which is convenient for replacing the filter membrane is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a high-pressure filter that is easy to replace the filter membrane in order to solve the above-mentioned problem. In order to facilitate the replacement of the high-pressure filter element, the existing filter is improved and conveniently and quickly disassembled so that the filter element is easy to insert and remove. However, if the filter element is not correctly positioned after installation, it may cause the filter element to shift or vibrate in the high-pressure operating environment, which will not only affect the performance of the filter, but also accelerate the wear of the material.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions. A high-pressure filter that is convenient for replacing filter membranes comprises: a fixed shell, connecting pipes are fixedly installed on both sides of the fixed shell, a supporting seat is fixedly installed on the bottom of the fixed shell, a filter element is arranged inside the fixed shell, and a replacement mechanism is arranged inside the fixed shell, and the replacement mechanism for quickly taking out the filter element and replacing the filter membrane is arranged inside the fixed shell, wherein the replacement mechanism comprises contact plates fixedly installed on both sides of the filter element, a positioning assembly is arranged inside the contact plate on one side, and a disassembly assembly is arranged on one side of the fixed shell, and the positioning assembly in the replacement mechanism can be used to quickly and stably position the filter element through vacuum adsorption after the filter element is replaced, so that the filter element can run stably after replacement without dislocation, and when replacement is needed, the fixed shell can be quickly opened through the disassembly assembly, and the filter element can be quickly taken out to replace the filter membrane, which is very convenient.

After the filter element is replaced, the contact plate at the bottom contacts the suction cup on one side of the support seat. At this time, the driving tube can be synchronously driven to rotate by rotating the driving block. When the driving tube rotates, the screw thread moves, and the driving screw moves inside the driving tube, synchronously pulling the piston plate inside the suction cup to move downward. By moving the piston plate downward, the suction cup can suck the adjacent contact plate tightly to achieve stable positioning of the filter element, so that the filter element is firmly fixed in position, preventing the filter element from shifting or vibrating during filter operation, and ensuring stable operation of the filter.

[0013] Preferably, one end of the support rod is fixedly connected to a second spring, and the other end of the second spring is fixedly connected to the extrusion plate. When the support rod moves inside the sealing tube, the corresponding second spring is synchronously squeezed to cause the second spring to deform. When the shielding shell is disassembled, the extrusion plate can be quickly reset by the second spring to facilitate next use.

[0014] The beneficial effects of the utility model are:

[0015] 1. The positioning component in the replacement mechanism can be used to quickly and stably position the filter element through vacuum adsorption after the filter element is replaced, so that the filter element can run stably after replacement without misalignment. When replacement is required, the fixed shell can be quickly opened by disassembling the component, and the filter element can be quickly taken out to replace the filter membrane, which is very convenient;

[0016] 2. By rotating the shielding shell, the fixing ring and the fixing shell are threadedly separated at the same time, so that the fixing shell can be quickly opened and the filter element can be easily taken out. When the shielding shell is installed, the extrusion plate is pressed against the contact plate on the upper side at the same time. When the extrusion plate is pressed, the sealing tube is driven to slide on the surface of the support rod, thereby squeezing the internal gas and achieving a tight press against the contact plate. This can increase the stability of the filter element. BRIEF DESCRIPTION OF THE DRAWINGS

After the filter element 2 is replaced, the positioning assembly 32 in the replacement mechanism 3 can be used to quickly and stably position the filter element 2 through vacuum adsorption, so that the filter element 2 can run stably after replacement without misalignment. When replacement is needed, the fixed shell 1 can be quickly opened through the disassembly assembly 33, and the filter element 2 can be quickly taken out to replace the filter membrane, which is very convenient.

[0024] like Figure 2 and Figure 3The cam 324 is provided with a screw rod 324 on one side of the suction cup 321, and the cam 325 is provided with a screw rod 324 on the other side of the suction cup 321. When the plate 323 moves downward, the suction cup 321 can suck the adjacent contact plate 31 to achieve stable positioning of the filter element 2, so that the filter element 2 is firmly fixed in place to prevent the filter element 2 from shifting or vibrating during filter operation, thereby ensuring stable operation of the filter. The positioning assembly 32 also includes a first spring 327 fixedly mounted on the outer side of the screw rod 324, and the two ends of the first spring 327 are fixedly connected to the piston plate 323 and the support seat 11 respectively. When the screw rod 324 moves inside the drive tube 325, the piston plate 323 synchronously squeezes the first spring 327, and the first spring 327 is deformed, so that the screw rod 324 can be more tightly connected to the drive tube 325, thereby increasing the stability of the connection between the two. A rubber ring 322 is fixedly mounted on one side of the suction cup 321, and one end of the rubber ring 322 is tightly pressed against the inner wall of the contact plate 31. When one end of the rubber ring 322 is tightly pressed against the inner wall of the contact plate 31, a good sealing effect can be formed, so that the adsorption effect of the suction cup 321 is better.

When the filter element 2 needs to be replaced, the positioning component 32 is first separated from one side of the filter element 2, and then the shielding shell 331 is rotated to synchronously separate the fixing ring 336 from the fixed shell 1 by threading, so as to realize the rapid opening of the fixed shell 1, so that the filter element 2 can be easily taken out. It is very convenient. The disassembly component 33 also includes a support rod 332 fixedly installed on the inner wall of the shielding shell 331, and a sealing tube 333 is slidably installed on the surface of the support rod 332. An extrusion plate 335 is fixedly installed on one end of the sealing tube 333, and one side of the extrusion plate 335 contacts the other side The plates 31 are in contact. When the shielding shell 331 is installed, the extrusion plate 335 is simultaneously pressed against the contact plate 31 located on the upper side. When the extrusion plate 335 is pressed against, the sealing tube 333 is driven to slide on the surface of the support rod 332, thereby squeezing the internal gas and achieving a tight press against the contact plate 31. This can increase the stability of the filter element 2 when used. One end of the support rod 332 is fixedly connected to a second spring 334, and the other end of the second spring 334 is fixedly connected to the extrusion plate 335. When the support rod 332 moves inside the sealing tube 333, the corresponding second spring 334 is synchronously squeezed, causing the second spring 334 to deform. When the shielding shell 331 is disassembled, the extrusion plate 335 can be quickly reset by resetting the second spring 334, which is convenient for next use.

[0026] When the filter element 2 is replaced, the contact plate 31 at the bottom contacts the suction cup 321 on one side of the support seat 11. At this time, the driving tube 325 can be synchronously driven to rotate by rotating the driving block 326. When the driving tube 325 rotates, the screw 324 moves in the thread, and the driving screw 324 moves inside the driving tube 325, and the piston plate 323 inside the suction cup 321 is synchronously pulled down. When the piston plate 323 moves downward, the suction cup 321 can be sucked and tightened to the adjacent contact plate 31, so as to achieve stable positioning of the filter element 2, so that the filter element 2 is firmly fixed in place, and the filter element 2 is prevented from shifting or vibrating during the operation of the filter, so as to ensure the stable operation of the filter. When the screw 324 moves inside the driving tube 325, the piston plate 323 synchronously squeezes the first spring 327, and the first spring 327 is deformed, which can The screw rod 324 can be more tightly connected with the driving tube 325, thereby increasing the stability of the connection between the two. When one end of the rubber ring 322 is pressed against the inner wall of the contact plate 31, a good sealing effect can be formed, so that the adsorption effect of the suction cup 321 is better. When the filter element 2 needs to be replaced, the positioning assembly 32 is first separated from one side of the filter element 2, and then the shielding shell 331 is rotated to synchronously separate the fixing ring 336 from the fixing shell 1 by thread, so as to realize quick opening of the fixing shell 1, so that the filter element 2 can be easily taken out. When the shielding shell 331 is installed, the extrusion plate 335 is simultaneously pressed against the contact plate 31 located on the upper side. When the extrusion plate 335 is pressed, the sealing tube 333 is driven to slide on the surface of the support rod 332, thereby squeezing the internal gas and achieving a tight press against the contact plate 31. This can increase the stability of the filter element 2 when used.
