Description

Technical Field

[0001] This application relates to the technical field of dust removal, and in particular to a compact filter cartridge mounting structure. Background Technology

[0002] The main purpose of the filter element mounting structure is to ensure the filter element is stably fixed and reliably sealed in the filtration system, and to facilitate installation and replacement, thereby guaranteeing filtration efficiency and preventing media leakage or contamination. Its design must be adaptable to different operating conditions, while also considering user convenience and long-term maintenance costs. It is widely used in water purifiers, air purification, automotive fuel systems, and industrial filtration.

[0003] The existing filter cartridge installation structure includes a mounting plate and multiple filter cartridges. The mounting plate has several through slots into which the filter cartridges are inserted one by one. Each filter cartridge has a flange, which is fastened to the mounting plate with bolts to achieve stable installation of the filter cartridge.

[0004] Regarding the aforementioned technologies, when periodically disassembling the filter element for maintenance, staff need to use tools to remove or tighten the bolts, which is time-consuming and labor-intensive, resulting in low filter element maintenance efficiency. Utility Model Content

[0005] To improve the maintenance efficiency of filter elements, this application provides a compact filter element mounting structure.

[0006] The compact filter element mounting structure provided in this application adopts the following technical solution:

[0007] A compact filter cartridge mounting structure includes a mounting plate and a filter cartridge. The mounting plate has a slot for inserting and fitting the filter cartridge into the slot. An annular plate is fixedly mounted at the slot of the mounting plate. A placement groove is formed on the side of the annular plate opposite to the mounting plate. A connecting plate is fitted onto one end of the filter cartridge. The connecting plate and the filter cartridge are connected and inserted and fitted into the placement groove. A movable groove is formed on the side wall of the annular plate. The movable groove and the placement groove are connected. A locking rod is slidably connected to the annular plate at the movable groove. A locking groove is formed on the side wall of the connecting plate. The locking rod and the locking groove are engaged and fitted into each other.

[0008] By adopting the above technical solution, the connecting plate is first connected to the filter element. Then, the filter element is moved so that one end of the filter element passes through the annular plate and the slot. The filter element drives the connecting plate to move, and the connecting plate gradually moves into the mounting groove. After the connecting plate moves to the set position, the locking rod and the locking groove are aligned. The locking rod moves towards the locking groove, and one end of the locking rod engages in the locking groove, realizing the locking and fixing of the connecting plate and the annular plate. This achieves the connection between the filter element and the mounting plate, completing the installation of the filter element. When maintaining the filter element, the locking rod is pulled away from the connecting plate, and the locking rod and the locking groove disengage, releasing the locking and fixing of the connecting plate and the annular plate. Moving the filter element away from the annular plate causes the filter element to disengage from the mounting plate. This eliminates the need for workers to use tools to disassemble or fix the bolts, saving time and improving the maintenance efficiency of the filter element.

[0009] Optionally, the annular plate has a limiting groove on the side wall of the moving groove, and a limiting block is slidably connected to the annular plate in the limiting groove. The side of the limiting block facing the moving groove is fixedly connected to the locking rod. A first spring is fixed between the limiting block and the side wall of the limiting groove, and the side of the locking rod facing the placement groove is set as an inclined surface.

[0010] By adopting the above technical solution, during the process of the connecting plate moving towards the placement groove, the connecting plate first contacts the inclined surface of the locking rod and pushes the locking rod towards the moving groove. The locking rod drives the limiting block to move, and the first spring is stretched. After the connecting plate moves to the set position, the locking rod and the locking groove are aligned, the first spring is contracted, and the limiting block is driven to move. The limiting block drives the locking rod to move, and one end of the locking rod extends into the locking groove, realizing the locking and fixing of the connecting plate and the annular plate. There is no need for the staff to manually move the locking rod towards the connecting plate, thus providing convenience for the staff.

[0011] Optionally, a pull plate is fixed at the end of the lever away from the mounting groove, and the pull plate is located outside the annular plate.

[0012] By adopting the above technical solution, when maintaining the filter element, the pull plate is pulled away from the annular plate. The pull plate moves the clamping rod, and the clamping rod disengages from the clamping groove. The pull plate provides convenience for moving the clamping rod.

[0013] Optionally, the outer wall of one end of the filter element is provided with threads, and the connecting plate and the threaded end of the filter element are threadedly connected.

[0014] By adopting the above technical solution, when maintaining the filter element, the connecting plate is turned off by turning the connecting plate, making it less likely for the connecting plate to affect the maintenance of the filter element.

[0015] Optionally, a protective cover is provided on the side of the connecting plate away from the mounting plate. The protective cover is fitted over the filter element and the protective cover and the filter element are slidably connected. A fixing groove is provided on the outer side wall of the protective cover, and a fixing component that can be fixedly separated from the protective cover is provided on the connecting plate.

[0016] By adopting the above technical solution, after the connecting plate and the filter element are connected, the protective cover is put on the outside of the filter element. The protective cover is moved, and one end of the protective cover abuts against the connecting plate. The fixing component fixes the protective cover. The threads on the filter element are inside the protective cover. The protective cover blocks the dust, making it difficult for dust to adhere to the threads of the filter element.

[0017] Optionally, the upper surface of the connecting plate is provided with a sliding groove, which is connected to the slot. The fixing component includes a sliding rod and a fixing rod. One end of the sliding rod is located in the slot and is slidably connected to the connecting plate. The other end of the sliding rod extends through the sliding groove to the outside of the connecting plate. The end of the sliding rod outside the connecting plate is fixedly connected to the fixing rod. The fixing rod and the fixing slot are inserted and adapted. A second spring is fixed between one side wall of the sliding rod and the slot. The elastic force of the second spring is less than that of the first spring.

[0018] By adopting the above technical solution, during the process of the locking rod moving towards the slot, the locking rod first contacts the sliding rod and pushes the sliding rod to move towards the protective cover. The second spring is compressed, and the sliding rod drives the fixing rod to move. One end of the fixing rod extends into the fixing slot, thereby realizing the fixing of the protective cover and the connecting plate.

[0019] Optionally, a baffle is fixed to the side wall of the sliding rod outside the connecting plate. The baffle is located on the side of the sliding rod away from the protective cover, and the baffle abuts against the connecting plate.

[0020] By adopting the above technical solution, as the slide rod moves toward the protective cover, the slide rod drives the baffle to move. After the fixed rod is engaged in the fixed groove, the baffle blocks the slide groove, making it difficult for dust to enter the slide groove and the slot.

[0021] Optionally, a sealing gasket is fixed to the side of the connecting plate facing the mounting plate.

[0022] By adopting the above technical solution, after the connecting plate and the annular plate are connected, the sealing gasket and the bottom wall of the mounting groove of the annular plate are tightly abutted, so that dust is not easy to move from the annular plate to the top of the mounting plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By extending one end of the clamping rod into the clamping groove, the connecting plate and the annular plate are clamped and fixed, thereby connecting the mounting plate and the filter element. When maintaining the filter element, move the clamping rod away from the annular plate, and the clamping rod and the clamping groove will disengage, releasing the connection between the mounting plate and the filter element. Move the filter element away from the mounting plate, and the filter element will disengage from the mounting plate. This eliminates the need for workers to use tools to disassemble or fix the bolts, saving time and improving the maintenance efficiency of the filter element.

[0025] 2. The protective cover prevents dust from easily entering the threaded grooves of the filter element, facilitating the separation of the connecting plate and the filter element;

[0026] 3. The baffle design prevents dust from easily entering the slots and slides, facilitating the movement of the slide bar. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0034] This application discloses a compact filter cartridge mounting structure.

[0035] refer to Figure 1 A compact filter element 2 mounting structure includes a mounting plate 1, with multiple annular plates 3 connected to one side of the mounting plate 1. The annular plates 3 are parallel to the mounting plate 1 and are arranged in an array. Filter elements 2 are provided at each of the annular plates 3, and the length direction of the filter elements 2 is perpendicular to the mounting plate 1.

[0036] refer to Figure 1 and Figure 2The mounting plate 1 has slots 11 through the annular plate 3. The filter element 2 is inserted into the slots 11 and the annular plate 3. The annular plate 3 has a placement groove 31 on the side away from the mounting plate 1. The placement groove 31 penetrates the inner wall of the annular plate 3. One end of the filter element 2 is fitted with a connecting plate 4. The connecting plate 4 is perpendicular to the filter element 2 and is threadedly connected to the filter element 2. The connecting plate 4 and the placement groove 31 are inserted into each other. The two opposite sides of the connecting plate 4 have slots 41. The two opposite sides of the annular plate 3 have moving grooves 32. The annular plate 3 is slidably connected to a locking rod 33 at the moving groove 32. The end of the locking rod 33 away from the placement groove 31 extends out of the annular plate 3. The locking rod 33 and the slot 41 are engaged.

[0037] First, connect the connecting plate 4 and the filter element 2 with threads. Then, move the filter element 2, with one end of the filter element 2 passing through the annular plate 3 and the slot 11. The filter element 2 drives the connecting plate 4 to move, and the connecting plate 4 is gradually embedded into the mounting groove 31. After the connecting plate 4 moves to the set position, the locking rod 33 and the locking groove 41 are aligned. The locking rod 33 moves towards the connecting plate 4, and one end of the locking rod 33 is engaged in the locking groove 41, thereby realizing the locking and fixing of the connecting plate 4 and the annular plate 3, and further realizing the connection between the filter element 2 and the mounting plate 1. During maintenance, move the locking rod 33 away from the annular plate 3, so that the locking rod 33 and the locking groove 41 are disengaged, and the connection between the mounting plate 1 and the filter element 2 is released.

[0038] refer to Figure 2 , Figure 3 and Figure 4 The annular plate 3 has limiting grooves 34 on the opposite side walls of the moving groove 32 along the length of the moving groove 32. The annular plate 3 is slidably connected to the limiting block 35 in the limiting groove 34. The limiting block 35 is fixedly connected to the side of the moving groove 32 facing the limiting block 35 and the locking rod 33. A first spring 36 is fixed between the limiting block 35 and the side wall of the limiting groove 34 near the placement groove 31. A pull plate 37 is fixed at the end of the locking rod 33 away from the placement groove 31. The pull plate 37 is perpendicular to the locking rod 33. The side wall of the locking rod 33 away from the pull plate 37 is set as an inclined surface. A sealing gasket 8 is fixed on the side of the connecting plate 4 facing the bottom wall of the placement groove 31. The sealing gasket 8 is ring-shaped. In this embodiment, the sealing gasket 8 is made of rubber.

[0039] During the process of the connecting plate 4 moving towards the mounting groove 31, the connecting plate 4 first contacts the inclined surface of the locking rod 33 and pushes the locking rod 33 towards the moving groove 32. The locking rod 33 drives the limiting block 35 to move, and the first spring 36 is stretched. After the connecting plate 4 moves to the set position, the sealing gasket 8 and the bottom wall of the mounting groove 31 are tightly fitted, making it difficult for dust under the mounting plate 1 to move upward from the annular plate 3. The locking rod 33 and the locking groove 41 are aligned, and the first spring 36 retracts, driving the limiting block 35 to move towards the mounting groove 31. The limiting block 35 drives the locking rod 33 to move, and one end of the locking rod 33 is locked into the locking groove 41. When the locking rod 33 needs to be separated from the locking groove 41, the pull plate 37 moves away from the annular plate 3, and the pull plate 37 drives the locking rod 33 to move.

[0040] refer to Figure 1 , Figure 2 and Figure 5 The annular plate 3 has a first positioning groove 38 on the opposite side walls of the mounting groove 31. The first positioning groove 38 penetrates the side wall of the annular plate 3 away from the mounting plate 1. The opposite side walls of the connecting plate 4 are fixed with a first positioning rod 44. The first positioning rod 44 and the first positioning groove 38 are inserted and adapted to each other.

[0041] When the connecting plate 4 moves toward the mounting groove 31, the first positioning rod 44 and the first positioning groove 38 are first aligned and correspond one-to-one. During the movement of the connecting plate 4, the first positioning rod 44 is driven to move and gradually embedded into the first positioning groove 38. After the connecting plate 4 moves to the set position, the locking rod 33 and the locking groove 41 are aligned. The setting of the first positioning rod 44 and the first positioning groove 38 provides convenience for the alignment of the locking rod 33 and the locking groove 41.

[0042] refer to Figure 2 , Figure 3 and Figure 4 A protective cover 5 is fitted on the filter element 2. The protective cover 5 is located on the side of the connecting plate 4 away from the mounting plate 1. The protective cover 5 and the filter element 2 are slidably connected. Fixing grooves 51 are provided on the two opposite outer side walls of the protective cover 5. A fixing component 6 that can be fixedly separated from the protective cover 5 is provided on the connecting plate 4.

[0043] The connecting plate 4 has two sliding grooves 42 on the side facing the protective cover 5. The sliding grooves 42 and the slots 41 are connected and correspond one-to-one. The fixing component 6 includes a sliding rod 61 and a fixing rod 62. There are two sliding rods 61 and two fixing rods 62, and they correspond one-to-one. One end of the sliding rod 61 is in the slot 41, and the other end of the sliding rod 61 extends out of the connecting plate 4 from the sliding groove 42. The length direction of the sliding rod 61 is perpendicular to the connecting plate 4. The sliding rod 61 and the connecting plate 4 are slidably connected. A second spring 43 is fixed between one side wall. The elastic force of the second spring 43 is less than that of the first spring 36. The end of the slide rod 61 outside the connecting plate 4 is fixedly connected to one end of the fixing rod 62. The fixing rod 62 is parallel to the connecting plate 4. The fixing rod 62 and the fixing groove 51 are inserted and matched one by one. A baffle 7 is fixed on the side of the slide rod 61 away from the protective cover 5. The baffle 7 is parallel to the connecting plate 4. The baffle 7 is located on the side of the connecting plate 4 away from the mounting plate 1. The baffle 7 and the connecting plate 4 abut against each other.

[0044] After the connecting plate 4 and the filter element 2 are connected, the protective cover 5 is fitted onto the filter element 2, and one end of the protective cover 5 abuts against the connecting plate 4. The threads on the filter element 2 are inside the protective cover 5, which blocks dust, making it difficult for dust to enter the threaded groove of the filter element 2. Then, the filter element 2 is moved, which drives the connecting plate 4 and the protective cover 5 to move. After the locking rod 33 and the locking groove 41 are aligned, the locking rod 33 moves towards the locking groove 41. During this process, the locking rod 33 first contacts the sliding rod 61 and pushes the sliding rod 61 to move. The second spring 43 is compressed, and the sliding rod 61 drives the fixing rod 62 to move. One end of the fixing rod 62 extends into the fixing groove 51, completing the fixation of the protective cover 5. At the same time, the sliding rod 61 drives the baffle 7 to move. After the fixing rod 62 moves to the set position, the baffle 7 blocks the sliding groove 42, making it difficult for dust to fall into the locking groove 41. After the locking rod 33 and the locking groove 41 are disengaged, the second spring 43 releases its elastic force, pushing the slide rod 61 to move. The slide rod 61 drives the fixing rod 62 to move, and the fixing rod 62 and the fixing groove 51 are disengaged, releasing the fixation of the protective cover 5.

[0045] refer to Figure 1 , Figure 2 and Figure 5 The upper surface of the connecting plate 4 is provided with a second positioning groove 45, and the bottom end of the protective cover 5 is fixed with a second positioning rod 52. The length direction of the second positioning rod 52 is parallel to the length direction of the filter element 2, and the second positioning rod 52 and the second positioning groove 45 are inserted and matched.

[0046] When the protective cover 5 is moved toward the connecting plate 4, the protective cover 5 is rotated so that the second positioning rod 52 and the second positioning groove 45 are aligned. Then, the protective cover 5 is moved toward the connecting plate 4, and the second positioning rod 52 is gradually inserted into the second positioning groove 45. The setting of the second positioning rod 52 and the second positioning groove 45 facilitates the alignment of the fixing rod 62 and the fixing groove 51.

[0047] The implementation principle of the compact filter element 2 installation structure in this application embodiment is as follows: First, the connecting plate 4 is sleeved on the filter element 2 and threaded. After the connection is completed, the filter element 2 is moved, and one end of the filter element 2 passes through the annular plate 3 and the slot 11. At the same time, the filter element 2 drives the connecting plate 4 to move. During the process of the connecting plate 4 being gradually embedded into the mounting groove 31, the connecting plate 4 first contacts the inclined surface of the locking rod 33 and pushes the locking rod 33 to move towards the moving groove 32. The first spring 36 is stretched. After the connecting plate 4 moves to the set position, the slot 41 and the locking rod 33 are aligned. The first spring 36 is contracted, driving the locking rod 33 to move towards the connecting plate 4. One end of the locking rod 33 is engaged in the slot 41, realizing the engagement and fixation of the connecting plate 4 and the annular plate 3, thereby realizing the fixation of the filter element 2 and the mounting plate 1. During maintenance, pull the pull plate 37 away from the annular plate 3. The pull plate 37 moves the locking rod 33, disengaging the locking rod 33 from the locking groove 41 and releasing the connection between the filter element 2 and the mounting plate 1. Pull the filter element 2 away from the mounting plate 1 to disengage the filter element 2 from the mounting plate 1, allowing for maintenance of the filter element 2. This eliminates the need for staff to use tools to disassemble or tighten bolts, saving time and improving the efficiency of filter element 2 maintenance.

[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
