Description

Technical Field

[0001] This invention relates to the technical field of detachable multi-section horizontal filter equipment, specifically a detachable multi-section horizontal filter. Background Technology

[0002] Multi-stage horizontal filters typically refer to horizontal multi-media filters, a type of water treatment equipment. By filling a horizontal pressure vessel with filter media of different particle sizes and densities (such as anthracite, quartz sand, manganese sand, etc.), and utilizing a gradient filter layer design of "coarse at the top and fine at the bottom, light at the top and heavy at the bottom," suspended solids, colloids, and large particulate impurities in the water are intercepted step by step, thereby achieving efficient purification.

[0003] In the existing technology, after a period of use, in order to prevent the filter cartridge inside the filter from becoming clogged, the filter cartridge needs to be disassembled regularly for cleaning or replacement. However, most filter cartridges are installed inside the filter with bolts, which makes the installation or disassembly of the filter cartridge cumbersome and reduces the efficiency of filter cartridge installation and disassembly. Summary of the Invention

[0004] The purpose of this invention is to provide a detachable multi-section horizontal filter to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a detachable multi-section horizontal filter, comprising a filter, an outlet pipe fixedly connected to the surface of the filter, an inlet pipe fixedly connected to the end of the filter, a sealing door hinged to the end of the filter away from the inlet pipe, a moving groove formed in the inner wall of the filter, a sliding plate slidably connected to the inner wall of the moving groove, a fine filter barrel fixedly connected to the side of the sliding plate away from the moving groove, a coarse filter barrel fixedly connected to the inner wall of the fine filter barrel, and further comprising; A limiting mechanism, the limiting mechanism including a driven rod, a return spring fixedly connected to the surface of the driven rod, and a contact ring fixedly connected to the end of the driven rod; A sealing mechanism, the sealing mechanism including a connecting rod, the surface of which is fixedly connected to a buffer elastic rod; A quick-release mechanism includes a push rod, the end of which is hinged to a pressing plate, and a force-bearing telescopic rod is fixedly connected to the surface of the pressing plate.

[0006] Furthermore, the inner walls of the water outlet pipe and the water inlet pipe are connected to the inner wall of the filter, the outer wall of the sealing door and the end of the filter are both provided with connection holes, the inner wall of the filter is provided with grooves, and the surface of the fine filter barrel is provided with slots.

[0007] Furthermore, the limiting mechanism includes a slide rod, a limiting ring is fixedly connected to the end of the slide rod, a force-bearing inclined block is fixedly connected to the surface of the limiting ring, a force-bearing spring is fixedly connected to the surface of the slide rod, and a driven ring is fixedly connected to the end of the driven rod away from the contact ring.

[0008] Furthermore, the end of the slide rod away from the limiting ring is slidably connected to the inner wall of the groove, the end of the force spring away from the slide rod is fixedly connected to the inner wall of the groove, the driven rod is close to the driven ring and penetrates the inner wall of the filter, and is fixedly connected to the surface of the driven ring, and both ends of the return spring are in contact with the surface of the contact ring and the inner wall of the filter.

[0009] Furthermore, the sealing mechanism includes a slider, a sealing ring is fixedly connected to the end of the connecting rod, a groove is provided on the inner wall of the filter, and a fixing ring is fixedly connected to the surface of the slider.

[0010] Furthermore, the surface of the slider is slidably connected to the inner wall of the groove, the end of the connecting rod away from the sealing ring is fixedly connected to the surface of the slider, and the end of the buffer elastic rod that was originally the connecting rod is fixedly connected to the surface of the contact ring.

[0011] Furthermore, the quick-release mechanism includes a support ring, the inner wall of which is fixedly connected to a bidirectional telescopic rod, the end of which is fixedly connected to a long plate, and the surface of which is fixedly connected to a limit ring.

[0012] Furthermore, the outer wall of the support ring is fixedly connected to the surface of the filter, the end of the force-bearing telescopic rod away from the button plate is fixedly connected to the surface of the support ring, the surface of the limiting retaining ring is in contact with the inner wall of the support ring, and the end of the push rod away from the button plate is hinged to the end of the long plate.

[0013] The present invention has the following beneficial effects: This invention utilizes a limiting mechanism. First, the operator pushes the fine filter bucket towards the inlet pipe. This movement causes the coarse filter bucket to move towards the inlet pipe as well, simultaneously causing the sliding plate to slide along the inner wall of the moving groove towards the inlet pipe. As the fine filter bucket moves, the locking groove also moves towards the inlet pipe. During the sliding process, the sliding plate contacts the surface of the contact ring, pushing it towards the inlet pipe. When the contact ring moves, it pushes the driven rod towards the inlet pipe and simultaneously compresses the return spring. When the return spring is compressed, it contracts towards the inlet pipe. As the driven rod moves, it pushes the driven ring towards the inlet pipe. During the movement of the contact ring, it contacts the surface of the force-bearing inclined block, thus affecting the force-bearing inclined block. The compression process causes the inclined blocks to move closer together. As the inclined blocks move, they push the limiting ring to move closer together as well. When the end of the fine filter bucket reaches its position, it contacts the inner wall of the filter. The slot is precisely in the same position as the limiting ring, which contacts the inner wall of the slot as it moves into place, thus limiting the entire fine filter bucket. The movement of the limiting ring causes the sliding rod to slide closer together on the inner wall of the groove. As the sliding rod slides, it compresses the force spring, causing it to contract closer together. This effectively ensures that the limiting ring contacts the inner wall of the slot during its movement, thus limiting the entire fine filter bucket and achieving rapid installation, thereby improving installation efficiency.

[0014] This invention employs a sealing mechanism. When the contact ring moves, it pushes a buffer elastic rod towards the water inlet pipe. The buffer elastic rod, in turn, pushes a connecting rod towards the water inlet pipe. As the connecting rod moves, it causes a slider to slide along the inner wall of the trough towards the water inlet pipe, simultaneously moving the sealing ring towards the water inlet pipe. When the sealing ring reaches its position, it stops at the point where the outer wall of the fine filter barrel contacts the inner wall of the filter, thus sealing the fine filter barrel and preventing leakage during water intake. Simultaneously, the sliding rod moves, pushing a fixing ring towards each other. When the fixing ring reaches its position, it contacts the surface of the sealing ring, thus fixing it in place. This effectively seals the contact point between the fine filter barrel and the filter, preventing leakage. Furthermore, the fixing ring further secures the sealing ring, preventing it from loosening.

[0015] This invention employs a quick-release mechanism. During the movement of the driven ring, it contacts the surface of the limiting ring. Because the contact point between the limiting ring and the driven ring is angled, the driven ring compresses the limiting ring upon contact. When the limiting ring is compressed, it moves away from the driven ring. This movement pushes the long plate away from the driven ring, which in turn pulls the bidirectional telescopic rod to extend away from the driven ring. Simultaneously, the long plate pulls the end of the push rod away from the driven ring, while the other end of the push rod pulls the pressing plate towards the support ring. The movement of the pressing plate pushes the driven ring towards the support ring. The telescopic rod retracts towards the support ring. When the driven ring moves to the center position with the limiting ring, the limiting ring no longer exerts pressure. The elasticity of the telescopic rod pulls the long plate closer together. As the long plate moves, it pushes the limiting ring closer together, limiting the driven ring and causing its surface to contact the inner wall of the limiting ring, thus completing the installation. The sealing door is then closed, and water to be filtered is introduced into the filter through the inlet pipe. The water first enters the fine filter chamber, where it is filtered. Fine impurities are filtered onto the inner wall of the fine filter tank, and then the water is filtered again through the coarse filter tank. The coarse filter tank filters out larger impurities onto its inner wall. The filtered water is discharged through the outlet pipe. When replacing the entire fine filter tank, first open the sealing door, then press and hold the push plate and move it towards the support ring. As the push plate moves, it pushes the tension rod to retract towards the support ring, simultaneously moving the end of the push rod towards the support ring. The other end of the push rod pushes the long plate to move away from each other. As the long plate moves, it pulls the bidirectional telescopic rod to extend away from each other, simultaneously... The moving limit ring moves away from each other, thus separating the limit ring from the driven ring. After the limit ring separates from the driven rod, the driven ring will return to its original position through the elasticity of the return spring. At the same time, the limit ring will also separate from the slot. At this point, the fine filter can be removed as a whole, thus completing the disassembly. This effectively allows for the quick disassembly of the fine filter can, replacing the tedious steps of bolt installation and disassembly, and improving the efficiency of disassembly. The fine filter can also filter water through the coarse filter can, separating impurities of different sizes in the water and filtering them onto the inner walls of the fine filter can and coarse filter can.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8As shown, the present invention is a detachable multi-section horizontal filter, including a filter 1, an outlet pipe 2 fixedly connected to the surface of the filter 1, an inlet pipe 3 fixedly connected to the end of the filter 1, a sealing door 4 hinged to the end of the filter 1 away from the inlet pipe 3, a moving groove opened in the inner wall of the filter 1, a sliding plate 5 slidably connected to the inner wall of the moving groove, a fine filter barrel 6 fixedly connected to the side of the sliding plate 5 away from the moving groove, a coarse filter barrel 7 fixedly connected to the inner wall of the fine filter barrel 6, and also including; The limiting mechanism 10 includes a driven rod 15, a return spring 16 fixedly connected to the surface of the driven rod 15, and a contact ring 17 fixedly connected to the end of the driven rod 15. First, the operator pushes the fine filter bucket 6 to move towards the water inlet pipe 3. When the fine filter bucket 6 moves, it will drive the coarse filter bucket 7 to move towards the water inlet pipe 3. At the same time, it will also drive the slide plate 5 to slide on the inner wall of the moving groove towards the water inlet pipe 3. When the fine filter bucket 6 moves, it will drive the slot to move towards the water inlet pipe 3. During the sliding process of the slide plate 5, it will contact the surface of the contact ring 17 and push the contact ring 17 to move towards the water inlet pipe 3. The sealing mechanism 30 includes a connecting rod 32, and a buffer elastic rod 34 is fixedly connected to the surface of the connecting rod 32. When the contact ring 17 moves, it pushes the buffer elastic rod 34 to move towards the water inlet pipe 3. When the buffer elastic rod 34 moves, it pushes the connecting rod 32 to move towards the water inlet pipe 3. The quick-release mechanism 50 includes a push rod 54. When the long plate 53 moves, the end of the push rod 54 is pulled to move away from each other. The other end of the push rod 54 pulls the press plate 55 to move towards the support ring 51. The end of the push rod 54 is hinged to the press plate 55. The surface of the press plate 55 is fixedly connected to a force-bearing telescopic rod 56. When the press plate 55 moves, it pushes the force-bearing telescopic rod 56 to retract towards the support ring 51.

[0022] The inner walls of the water outlet pipe 2 and the water inlet pipe 3 are connected to the inner wall of the filter 1. The outer wall of the sealing door 4 and the end of the filter 1 are both provided with connection holes. The inner wall of the filter 1 is provided with grooves. The surface of the fine filter barrel 6 is provided with slots.

[0023] The limiting mechanism 10 includes a slide rod 11, with a limiting ring 12 fixedly connected to the end of the slide rod 11. When the driven rod 15 moves, it pushes the driven ring 18 to move towards the water inlet pipe 3. During the movement of the contact ring 17, it contacts the surface of the force-bearing inclined block 13 and squeezes the force-bearing inclined block 13, causing the force-bearing inclined block 13 to move closer to each other. When the force-bearing inclined block 13 moves, it pushes the limiting ring 12 to move closer to each other. At this time, when the end of the fine filter barrel 6 moves into place, it will contact the inner wall of the filter 1, and the slot is exactly in contact with the filter. The limiting ring 12 is in the same position. When the limiting ring 12 moves into place, it contacts the inner wall of the slot, thereby limiting the entire fine filter barrel 6. The surface of the limiting ring 12 is fixedly connected to the force-bearing inclined block 13, and the surface of the slide rod 11 is fixedly connected to the force-bearing spring 14. The end of the driven rod 15 away from the contact ring 17 is fixedly connected to the driven ring 18. When the contact ring 17 moves, it will push the driven rod 15 to move towards the water inlet pipe 3, and at the same time, it will squeeze the return spring 16. When the return spring 16 is squeezed, it will contract towards the water inlet pipe 3.

[0024] The end of the slide rod 11 away from the limiting ring 12 is slidably connected to the inner wall of the groove. The end of the force spring 14 away from the slide rod 11 is fixedly connected to the inner wall of the groove. The driven rod 15 is close to the driven ring 18 and passes through the inner wall of the filter 1, and is fixedly connected to the surface of the driven ring 18. Both ends of the return spring 16 are in contact with the surface of the contact ring 17 and the inner wall of the filter 1. When the limiting ring 12 moves, it will drive the slide rod 11 to slide in the inner wall of the groove towards each other. When the slide rod 11 slides, it will squeeze the force spring 14, causing the force spring 14 to contract in the direction of approaching each other. Effectively, during the movement of the limiting ring 12, it will contact the inner wall of the slot, thereby limiting the entire fine filter barrel 6 and achieving the effect of quick installation of the entire fine filter barrel 6, thus improving the installation efficiency.

[0025] The sealing mechanism 30 includes a slider 31 and a sealing ring 33 fixedly connected to the end of a connecting rod 32. When the connecting rod 32 moves, it drives the slider 31 to slide along the inner wall of the groove 35 toward the water inlet pipe 3, and at the same time, it also drives the sealing ring 33 to move toward the water inlet pipe 3. The inner wall of the filter 1 has a groove 35. A fixing ring 36 is fixedly connected to the surface of the slider 11. When the slider 11 moves, it pushes the fixing ring 36 to move toward each other. When the fixing ring 36 moves into place, it contacts the surface of the sealing ring 33, thereby fixing the sealing ring 33. The sealing ring 33 effectively seals the contact point between the fine filter barrel 6 and the filter 1, thereby preventing leakage. At the same time, the fixing ring 36 also fixes the sealing ring 33, thereby preventing the sealing ring 33 from loosening.

[0026] The surface of slider 31 is slidably connected to the inner wall of slide groove 35. The end of connecting rod 32 away from sealing ring 33 is fixedly connected to the surface of slider 31. When sealing ring 33 moves into position, it will stop at the position where the outer wall of fine filter barrel 6 contacts the inner wall of filter 1. At the same time, it will contact the outer wall of fine filter barrel 6 and the inner wall of filter 1, thereby sealing fine filter barrel 6 and preventing water leakage during water intake. The end of buffer elastic rod 34 that was originally connected to connecting rod 32 is fixedly connected to the surface of contact ring 17.

[0027] The quick-release mechanism 50 includes a support ring 51. A bidirectional telescopic rod 52 is fixedly connected to the inner wall of the support ring 51. A long plate 53 is fixedly connected to the end of the bidirectional telescopic rod 52. During the movement of the driven ring 18, it will contact the surface of the limiting ring 57. Since the contact position between the limiting ring 57 and the driven ring 18 is set at an angle, after the driven ring 18 contacts the limiting ring 57, it will squeeze the limiting ring 57. When the limiting ring 57 is squeezed, it will move away from each other. When the limiting ring 57 moves, it will push the long plate 53 to move away from each other. When the long plate 53 moves, it will pull the bidirectional telescopic rod 52 to extend away from each other. The surface of the long plate 53 is fixedly connected to the limiting ring 57. When the fine filter tank 6 needs to be replaced as a whole, first open the sealing door 4, then press and hold the button 55 and move it towards the support ring 51. When the button 55 moves, it will push the force-bearing telescopic rod 56 to retract towards the support ring 51, and at the same time, it will pull... The end of the push rod 54 moves toward the support ring 51, while the other end of the push rod 54 pushes the long plate 53 to move away from each other. When the long plate 53 moves, it pulls the bidirectional telescopic rod 52 to extend away from each other, and at the same time drives the limiting ring 57 to move away from each other, thereby separating the limiting ring 57 from the driven ring 18. When the limiting ring 57 separates from the driven rod 15, the driven ring 18 will be reset to its original position by the elasticity of the return spring 16. At the same time, the limiting ring 12 will also separate from the slot. At this time, the fine filter barrel 6 can be taken out as a whole, thereby completing the disassembly. It can effectively and quickly disassemble the fine filter barrel 6 as a whole, replacing the cumbersome steps of bolt installation and disassembly, and improving the efficiency of disassembly. The fine filter barrel 6 and the coarse filter barrel 7 filter the water, thereby separating and filtering impurities of different sizes in the water onto the inner walls of the fine filter barrel 6 and the coarse filter barrel 7.

[0028] The outer wall of the support ring 51 is fixedly connected to the surface of the filter 1. The end of the force-bearing telescopic rod 56 away from the push plate 55 is fixedly connected to the surface of the support ring 51. The surface of the limiting ring 57 is in contact with the inner wall of the support ring 51. When the driven ring 18 moves to the center position with the limiting ring 57, the limiting ring 57 is no longer under pressure and is pulled by the elasticity of the bidirectional telescopic rod 52 to move the long plate 53 toward each other. When the long plate 53 moves, it pushes the limiting ring 57 toward each other. When the limiting ring 57 moves, it limits the driven ring 18, thereby causing the driven ring 1 to move closer to the filter 1. The surface of 8 contacts the inner wall of the limiting ring 57 to complete the installation. Then the sealing door 4 is closed, and the water to be filtered is introduced into the interior of the filter 1 through the water inlet pipe 3. After the water enters the interior of the filter 1, it will first enter the interior of the fine filter barrel 6 and filter the fine impurities in the water onto the inner wall of the fine filter barrel 6. Then the water is filtered through the coarse filter barrel 7, so that the coarse filter barrel 7 filters the larger impurities in the water onto the inner wall of the coarse filter barrel 7. The filtered water will be discharged through the water outlet pipe 2. The end of the push rod 54 away from the push plate 55 is hinged to the end of the long plate 53.

[0029] In use, the operator first pushes the fine filter bucket 6 towards the inlet pipe 3. As the fine filter bucket 6 moves, it also moves the coarse filter bucket 7 towards the inlet pipe 3. Simultaneously, it causes the sliding plate 5 to slide along the inner wall of the moving groove towards the inlet pipe 3. While the fine filter bucket 6 moves, it also causes the retaining groove to move towards the inlet pipe 3. During the sliding process, the sliding plate 5 contacts the surface of the contact ring 17, pushing the contact ring 17 towards the inlet pipe 3. When the contact ring 17 moves, it pushes the driven rod 15 towards the inlet pipe 3, simultaneously compressing the return spring 16. When the return spring 16 is compressed, it contracts towards the inlet pipe 3. As the driven rod 15 moves, it pushes the driven ring 18 towards the inlet pipe 3. During the movement of the contact ring 17, it will contact the surface of the force-bearing inclined block 13 and squeeze the force-bearing inclined block 13, causing the force-bearing inclined block 13 to move in a direction closer to each other. When the force-bearing inclined block 13 moves, it will push the limiting ring 12 to move in a direction closer to each other. At this time, when the end of the fine filter barrel 6 moves into place, it will contact the inner wall of the filter 1, and the slot is exactly in the same position as the limiting ring 12. When the limiting ring 12 moves into place, it will contact the inner wall of the slot, thereby limiting the entire fine filter barrel 6. When the limiting ring 12 moves, it will drive the slide rod 11 to slide in a direction closer to each other on the inner wall of the groove. When the slide rod 11 slides, it will squeeze the force spring 14, causing the force spring 14 to contract in a direction closer to each other. When the contact ring 17 moves, it will squeeze the force spring 14, causing the force spring 14 to contract in a direction closer to each other. As ring 17 moves, it pushes buffer elastic rod 34 towards inlet pipe 3. When buffer elastic rod 34 moves, it pushes connecting rod 32 towards inlet pipe 3. When connecting rod 32 moves, it drives slider 31 to slide on inner wall of slide groove 35 towards inlet pipe 3. At the same time, it also drives sealing ring 33 towards inlet pipe 3. When sealing ring 33 moves into position, it stops at the position where the outer wall of fine filter barrel 6 contacts the inner wall of filter 1, thus sealing fine filter barrel 6 and preventing water leakage during water intake. As sliding rod 11 moves, it pushes fixing ring 36 towards each other. When fixing ring 36 moves into position... The driven ring 18 will contact the surface of the sealing ring 33, thereby fixing the sealing ring 33. During the movement of the driven ring 18, it will contact the surface of the limiting ring 57. Since the contact position between the limiting ring 57 and the driven ring 18 is set at an angle, after the driven ring 18 contacts the limiting ring 57, it will squeeze the limiting ring 57. When the limiting ring 57 is squeezed, it will move away from each other. When the limiting ring 57 moves, it will push the long plate 53 to move away from each other. When the long plate 53 moves, it will pull the bidirectional telescopic rod 52 to extend away from each other. At the same time as the long plate 53 moves, it will pull the end of the push rod 54 to move away from each other. The other end of the push rod 54 will pull the pressing plate 55 to move towards the support ring 51.When the push plate 55 moves, it pushes the force-bearing telescopic rod 56 to retract towards the support ring 51. When the driven ring 18 moves to the center position with the limiting ring 57, the limiting ring 57 no longer exerts pressure. The elasticity of the bidirectional telescopic rod 52 pulls the long plate 53 towards each other. When the long plate 53 moves, it pushes the limiting ring 57 towards each other. As the limiting ring 57 moves, it limits the driven ring 18, causing the surface of the driven ring 18 to contact the inner wall of the limiting ring 57, thus completing the installation. Then, the sealing door 4 is closed, and the water to be filtered enters the filter 1 through the inlet pipe 3. After entering the filter 1, the water first enters the fine filter tank 6, where it filters out small impurities onto the inner wall. Then, it passes through the coarse filter tank 7, which filters out larger impurities. The filtered water is discharged through the outlet pipe 2 from the inner wall of the filter bucket 7. When replacing the entire fine filter bucket 6, first open the sealing door 4, then press and hold the push plate 55 and move it towards the support ring 51. As the push plate 55 moves, it will push the force-bearing telescopic rod 56 to retract towards the support ring 51, and at the same time, it will drive the end of the push rod 54 to move towards the support ring 51. The other end of the push rod 54 will push the long plate 53 to move away from each other. When the long plate 53 moves, it will pull the bidirectional telescopic rod 52 to extend away from each other, and at the same time, it will drive the limiting ring 57 to move away from each other, thereby separating the limiting ring 57 from the driven ring 18. When the limiting ring 57 separates from the driven rod 15, the driven ring 18 will be returned to its original position by the elasticity of the return spring 16. At the same time, the limiting ring 12 will also separate from the slot. At this time, the entire fine filter bucket 6 can be removed, thus completing the disassembly.
