Description

Technical Field

[0001] The utility model relates to the technical field of quickly detachable filtering devices, in particular to a quickly detachable filtering device. Background Art

[0002] The scale of industrial production has expanded rapidly, and the demand for filtration technology has also increased. In many industries such as chemical, pharmaceutical, and food, it is necessary to effectively filter raw materials, intermediate products, and finished products. For example, in the chemical industry, filtration devices are used to separate the products and impurities after chemical reactions. Early industrial filtration devices were mainly simple mesh filters, whose structure is similar to that of today's sieves. Solid particles are retained by the size of the mesh. These filters are usually woven from metal wire and can effectively remove larger solid impurities.

[0003] Existing filter devices are usually fixed inside the housing when in use. After filtering is completed, the filter holes of the filter device are usually clogged with particles, and then they need to be cleaned. Since they are fixed inside the housing, cleaning is time-consuming and labor-intensive, which reduces the practicality of the filter device. Therefore, it is necessary to propose a filter device that can be quickly disassembled.

[0004] The existing patent (publication number: CN219848342U) is a quickly detachable filter device. Through the arrangement of a locking rod, a moving mechanism, a rotating mechanism, a filter plate and a fixed block, when the filter plate needs to be cleaned, the locking rod is driven closer through the cooperation of the rotating mechanism and the moving mechanism, and the approaching locking rod can be disengaged from the fixed through-hole on one side of the fixed block. After disengagement, the filter plate can be removed, saving time and effort, facilitating the replacement or cleaning of the filter plate, and improving the practicality of the filter device.

Moreover, the filter device has a single-layer filter plate inside, and the filtering effect is easily reduced after long-term use, resulting in reduced filtering quality.

[0006] For this purpose, a quickly detachable filtering device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-5 , this utility model provides a technical solution:

[0030] A quickly detachable filter device includes a housing 1, a groove 2 is formed on the top of the housing 1, a filter cartridge 3 is disposed inside the housing 1, fixing components 4 are disposed on both sides of the filter cartridge 3, and an auxiliary component 5 is disposed inside the filter cartridge 3;

[0031] The fixing assembly 4 includes a support plate 401 fixedly connected to the top of the filter cartridge 3, and support blocks 402 are fixedly connected on both sides of the support plate 401. A placement groove 403 is provided inside the support block 402, and a fixing rod 404 is slidably connected inside the placement groove 403. The bottom of the fixing rod 404 is fixedly connected to a limiting circular plate 405, and the outer side of the limiting circular plate 405 is slidably connected to the placement groove 403. The top of the limiting circular plate 405 is fixedly connected to an auxiliary spring 406, and a limiting groove 407 is provided at the bottom of the fixing rod 404. The inside of the limiting groove 407 is fixedly connected to a limiting spring 408, and the outer side of the limiting spring 408 is fixedly connected to a limiting block 409.

[0032] In this embodiment, the filter cartridge 3 is locked and fixed to the housing 1 by the limiting block 409 at the bottom of the fixing rod 404. When the filter cartridge 3 needs to be removed, the fixing rod 404 is moved upward, and then the fixing rod 404 drives the limiting circular plate 405 to move. Then the limiting circular plate 405 generates an upward pressure on the auxiliary spring 406 inside the placement groove 403, causing the auxiliary spring 406 to contract. Then, in the process of the limiting block 409 at the bottom of the fixing rod 404 moving upward, the limiting block 409 is tilted by the adjusting block 11. The surface effect is that when the limit block 409 moves, its adjustment block 11 will apply a lateral pressure to the limit block 409. This lateral force will cause the limit block 409 to overcome the elastic force of the limit spring 408, thereby compressing the limit spring 408. The limit block 409 moves out of the inside of the groove 2 to release the locking fixation of the limit block 409 on the outer shell 1 and the filter cartridge 3. Compared with the existing quickly detachable filter device, it realizes the rapid installation and disassembly of the filter cartridge 3, so as to facilitate the cleaning or replacement of the filter cartridge 3 and improve work efficiency.

[0033] Specifically, such as Figure 3 As shown, the auxiliary component 5 includes an adjusting rod 501 threadedly connected to the outside of the filter cartridge 3, a fixing plate 502 is provided inside the filter cartridge 3, and a card slot 503 is provided on both sides of the fixing plate 502. Both sides of the card slot 503 are fixedly connected with a return spring 504, and the inside of the return spring 504 is fixedly connected with a connecting block 505. The inner side of the connecting block 505 is clamped with the outer side of the adjusting rod 501, and the bottom of the fixing plate 502 is fixedly connected with a filter element cartridge 506.

[0034] Specifically, such as Figure 3 As shown, a sealing gasket 507 is bonded to the outside of the filter cartridge 3 , and the sealing gasket 507 is located on the outside of the adjustment rod 501 .

[0035] Specifically, such as Figure 3 As shown, both sides of the interior of the filter cartridge 506 are fixedly connected with fixing seats 508 , and the inner side of the fixing seats 508 is rotatably connected with a pull rod 509 .

[0036] In this embodiment: when the filter cartridge 506 needs to be removed, the adjusting rod 501 is rotated. Since the adjusting rod 501 is connected to the internal thread of the filter cartridge 3, when the adjusting rod 501 is rotated, the adjusting rod 501 will move outward, and then the limiting fixation of the connecting block 505 that is locked with it will be released during the outward movement of the adjusting rod 501, and then the compressed return spring 504 will drive the connecting block 505 to move until the adjusting rod 501 moves out of the inside of the card slot 503, and then the pull rod 509 is rotated to make the pull rod 509 upward, so as to facilitate the removal of the released filter cartridge 506 for maintenance and replacement. Compared with the existing quickly detachable filter device, it can further purify the fluid, improve the efficiency and effect of filtration, and also facilitate the disassembly and replacement of the filter cartridge 506.

[0037] Specifically, such as Figure 4 As shown, the outer side of the support plate 401 is fixedly connected to a fixing block 6, the outer side of the fixing block 6 is clamped with a mounting seat 7, the inner side of the top of the mounting seat 7 is fixedly connected to a connecting pipe 8, the outer side of the mounting seat 7 is inserted with a limiting rod 9, the inner side of the limiting rod 9 is connected to the internal thread of the fixing block 6, and the top of the connecting pipe 8 is bolted with a flange 10.

[0038] Specifically, such as Figure 4 As shown, a sealing sleeve 18 is provided on the top of the filter cartridge 3 , and the bottom of the sealing sleeve 18 is embedded in the top side of the filter element cartridge 506 .

[0039] In this embodiment: by setting a fixing block 6, a mounting seat 7, a connecting pipe 8, a threaded rod and a flange 10, when filtering, the mounting seat 7 is first clamped onto the fixing block 6, and then the limiting rod 9 is inserted and threadedly connected to ensure the sealing and fixation of the connecting pipe 8 and the filter cartridge 3, and then the connecting pipe 8 can be connected to the water source to be filtered through the flange 10 to achieve rapid filtration. By setting a sealing sleeve 18, when the filter cartridge 3 is installed, the sealing gasket 507 is in close contact with the inside of the outer shell 1 to perform a sealing role, thereby improving the sealing performance of the filtering device to ensure that the fluid is filtered through the filter element cartridge 506.

[0040] Specifically, such as Figure 5 As shown, adjustment blocks 11 are fixedly connected to both sides of the groove 2 , and the adjustment blocks 11 are located on top of the limiting block 409 .

[0041] Specifically, such as Figure 1 As shown, a support frame 12 is fixedly connected to the outer side of the bottom of the housing 1 , and an anti-slip pad 13 is bonded to the bottom of the support frame 12 , and the anti-slip pad 13 is made of rubber.

[0042] In this embodiment: by setting the adjusting block 11, when the filter cartridge 3 and the shell 1 are installed and fixed, its fixing rod 404 drives the limit block 409 to move downward, and then the adjusting block 11 will apply a lateral pressure to the limit block 409. This lateral force will cause the limit block 409 to overcome the elastic force of the limit spring 408, thereby compressing the limit spring 408, and then when the limit block 409 moves to the inside of the groove 2, when the limit block 409 is away from the pressure of the adjusting block 11, the pressure on the limit spring 408 is released, and then the limit spring 408 drives the limit block 409 to move, and then the limit block 409 is locked and fixed with the inside of the groove 2, thereby completing the installation and fixation of the filter cartridge 3. By setting the support frame 12 and the anti-slip pad 13, the support frame 12 can effectively support the shell 1, and at the same time the anti-slip pad 13 increases the friction between the ground and the support frame 12 to prevent the device from shaking during the filtration process.

[0043] Specifically, such as Figure 1 As shown, the bottom of the housing 1 is connected to a delivery pipe 14 , and an electromagnetic valve 15 is provided on the outside of the delivery pipe 14 .

[0044] Specifically, such as Figure 1 As shown, a top plate 16 is fixedly connected to the left side of the housing 1 , and a top cover 17 is rotatably connected to the top of the top plate 16 .

[0045] In this embodiment: by providing a delivery pipe 14 and an electromagnetic valve 15, after the filtration is completed, the opening and closing of the electromagnetic valve 15 is controlled as needed to adjust the delivery of the fluid, and the delivery of the fluid can be flexibly controlled to facilitate the operation and management of the filtration process and meet different filtration needs. By providing a top plate 16 and a top cover 17, when the device is not in use, the top cover 17 is rotated to make the top cover 17 contact and seal with the support plate 401 to prevent other pollutants from entering the interior of the filtration device and affecting its filtration efficiency.

[0046] Working principle: When using the quick-detachable filter device, when it is necessary to remove the filter cartridge 3, the fixing rod 404 is moved upward, and then the fixing rod 404 drives the limiting circular plate 405 to move, and then the limiting circular plate 405 generates an upward pressure on the auxiliary spring 406 inside the placement groove 403, causing the auxiliary spring 406 to contract, and then the limiting block 409 at the bottom of the fixing rod 404 moves upward. Since the limiting block 409 is affected by the inclined surface of the adjusting block 11, when the limiting block 409 moves, its adjusting block 11 will apply a lateral pressure to the limiting block 409. This lateral force will cause the limiting block 409 to overcome the elastic force of the limiting spring 408, thereby compressing the limiting spring 408. The limiting block 409 previously moved out of the groove 2 to release the locking fixation of the limiting block 409 on the housing 1 and the filter cartridge 3. When it is necessary to remove the filter element cartridge 506, by rotating the adjusting rod 5 When the filter element 506 is in the open position, the filter element 508 is in the open position, and the filter element 509 is in the open position, so that the filter element 506 is in the open position.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
