Description

Technical Field

[0001] This utility model relates to the field of box filters, and more particularly to a modular box filter. Background Technology

[0002] Box filters are a common type of filtration equipment widely used in water treatment, air purification, and liquid filtration. Their main function is to remove impurities or particulate matter from fluids, ensuring fluid cleanliness.

[0003] Existing technologies, such as the utility model patent with publication number CN220899788U, disclose a box-type filter. This patent uses a mounting plate and a filter tank with an inlet pipe and an outlet pipe fixed to the top of the mounting plate. A first housing and a second housing are located outside the filter tank and on the mounting plate. The second housing is located between the first housing and the filter tank, forming an accommodating space between the spaced-apart first and second housings. A first support rod and a second support rod are arranged inside the accommodating space, with the second support rod positioned between two adjacent first support rods. A third support rod is arranged perpendicular to the first support rods on the side of the second housing opposite to the first housing, with the filter tank located between the third support rods. The sides of the first and second support rods are connected to the first and second housings, respectively. This utility model box-type filter significantly improves the overall structural strength, avoids the filter tank bursting and causing debris to fly everywhere, and improves overall safety performance.

[0004] In daily use, it has been found that the design of existing box-type filters is not easy to disassemble, and the replacement of the filter screen becomes very troublesome, requiring additional tools or technicians to operate, which increases the complexity of maintenance. Moreover, the disassembly process for replacing the filter screen is complicated, which leads to prolonged equipment downtime and thus affects production efficiency. Especially in environments where frequent filter screen replacement is required, the extended downtime will have a significant impact. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular box-type filter.

[0006] To solve the above technical problems, this utility model provides a modular box-type filter, including: a box body, a disassembly structure, and a connecting structure. A filter screen is installed inside the box body, and the filter screen is connected to the box body via the disassembly structure. A connecting frame is provided on one side of the box body, and the connecting frame is connected to the box body via the connecting structure. A disassembly structure is provided at one end of the box body, and the disassembly structure includes two connecting rails connected to the box body. Sliding rods are slidably connected to the inner walls of the connecting rails. Connecting rods are fixedly connected to the ends of the two sliding rods that are close to each other. A cover plate is fixedly connected to the end of the connecting rod away from the sliding rod. The side of the cover plate away from the connecting rod is fixedly... The fixed connection has two fixed frames, and a bracket is slidably connected to the inner wall of the fixed frame. Elastic blocks are fixedly connected to both sides of the bracket, and the elastic blocks engage with the fixed frames. Two sliding frames are slidably connected to the end of the bracket away from the fixed frames, and the two sliding frames are fixedly connected to the housing. The filter screen is installed on the bracket. Two insertion holes and two slots are respectively opened on the side of the connecting rail away from the cover plate. An auxiliary rod is slidably connected to the inner wall of the sliding rod. A connecting block is fixedly connected to the end of the auxiliary rod away from the sliding rod. A spring is fitted onto the arc surface of the auxiliary rod, and both ends of the spring are fixedly connected to the connecting block and the sliding rod respectively. Four insertion rods are fixedly connected to the side of the connecting block near the sliding rod.

[0007] The aforementioned components achieve the following effects: When it is necessary to remove the bracket and filter screen inside the box, pull the slide rod to move it. The slide rod slides on the inner wall of the connecting rail, which in turn moves the connecting rod. The connecting rod moves the cover plate, which in turn moves the fixing frame. The fixing frame moves the bracket outward, separating the bracket from the slide frame. Then, hold the bracket and continue pulling the cover plate outward. The cover plate moves the fixing frame away from the elastic block on the bracket. Then, move the cover plate upward. After moving it to the appropriate position, pull the connecting block to move it. The connecting block moves the auxiliary rod to slide on the inner wall of the slide rod, which in turn stretches the spring. Then, align the insertion rod with the slot. Then, release the connecting block spring to retract it, causing the insertion rod to be inserted into the slot for fixation. When it is necessary to reset and fix the cover plate, insert the insertion rod into the insertion hole for fixation.

[0008] Preferably, the four inserts are adapted to two insertion holes and two slots respectively, and the cross-section of the inserts is circular.

[0009] Preferably, the connecting block is a rubber block, and the surface of the connecting block is rounded.

[0010] The effect achieved by the above components is that the rubber material can increase the friction between the hand and the connecting block, preventing slippage when pulling the connecting block.

[0011] Preferably, the auxiliary rod has a circular cross-section and is made of stainless steel.

[0012] The effect achieved by the above components is that the auxiliary rod can limit the spring, prevent the spring from deforming during use, and improve the service life of the spring.

[0013] Preferably, the elastic block has a rectangular cross-section and is a silicone block.

[0014] The effect achieved by the above components is that the elastic block has a certain degree of elasticity, which makes it easy to separate the elastic block from the fixed frame.

[0015] Preferably, both ends of the box are provided with a plurality of connecting structures, each connecting structure including a connecting plate, the connecting plate being fixedly connected to the box, a positioning rod being slidably connected to the inner wall of the connecting plate, a connecting ring being rotatably connected to the arc surface of the positioning rod, a plurality of retaining strips being fixedly connected to the arc surface of the connecting ring, a plurality of slots being opened on the inner wall of the connecting plate, and the positioning rod being fixedly connected to the connecting frame.

[0016] The effect achieved by the above components is as follows: when it is necessary to connect the connecting frame to the box, the connecting frame is pulled to move, the connecting frame drives the positioning rod to move, the positioning rod drives the connecting ring to move, the connecting ring drives the locking strip to move, and then the connecting ring and the locking strip pass through the connecting plate and the slot. After moving to the appropriate position, the connecting ring is rotated to move, the connecting ring drives the locking strip to move, and after moving to the appropriate angle, the locking strip abuts against the connecting plate, and then the connecting frame is connected and fixed to the box.

[0017] Preferably, the locking strip is adapted to the slot, and the locking strip is a stainless steel strip.

[0018] The effect achieved by the above components is that the stainless steel material can increase the service life of the clips and prevent them from rusting during use.

[0019] Compared with related technologies, the modular box filter provided by this utility model has the following beneficial effects:

[0020] By incorporating a disassembly and assembly structure, the existing box-type filter design is difficult to disassemble, making filter replacement extremely cumbersome and requiring additional tools or technicians, thus increasing maintenance complexity. Moreover, the complex disassembly process during filter replacement leads to prolonged equipment downtime, impacting production efficiency, especially in environments requiring frequent filter replacements. This device allows for easy disassembly of the housing, enabling the removal, replacement, or cleaning of the filter inside, significantly improving the efficiency of box-type filter maintenance and replacement.

[0021] By setting up a connection structure, it is possible to easily connect the box filter to external equipment, and after connection, the filter can be quickly disassembled for maintenance. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 6The present invention provides a modular box filter, comprising: a box body 1, a disassembly structure 4, and a connecting structure 5. A filter screen 3 is provided inside the box body 1, and the filter screen 3 is connected to the box body 1 by means of the disassembly structure 4. A connecting frame 2 is provided on one side of the box body 1, and the connecting frame 2 is connected to the box body 1 by means of the connecting structure 5. A disassembly structure 4 is provided at one end of the box body 1, and several connecting structures 5 are provided at both ends of the box body 1.

[0032] In the embodiments of this utility model, please refer to Figures 2 to 5The disassembly and assembly structure 4 includes two connecting rails 404, which are connected to the housing 1. A sliding rod 410 is slidably connected to the inner wall of each connecting rail 404. A connecting rod 405 is fixedly connected to the end of each sliding rod 410 that is close to the other. A cover plate 414 is fixedly connected to the end of each connecting rod 405 that is away from the sliding rod 410. Two fixing frames 403 are fixedly connected to the side of the cover plate 414 away from the connecting rod 405. A bracket 401 is slidably connected to the inner wall of each fixing frame 403. Elastic blocks 406 are fixedly connected to both sides of each bracket 401, and the elastic blocks 406 engage with the fixing frames 403. The bracket 401 is positioned away from the fixing frames 403. Two sliding frames 402 are slidably connected to one end of 03. The two sliding frames 402 are fixedly connected to the box 1. The filter screen 3 is installed on the bracket 401. Two insertion holes 408 and two slots 409 are respectively opened on the side of the connecting rail 404 away from the cover plate 414. An auxiliary rod 413 is slidably connected to the inner wall of the sliding rod 410. A connecting block 407 is fixedly connected to the end of the auxiliary rod 413 away from the sliding rod 410. A spring 412 is sleeved on the arc surface of the auxiliary rod 413. The two ends of the spring 412 are fixedly connected to the connecting block 407 and the sliding rod 410 respectively. Four insertion rods 411 are fixedly connected to the side of the connecting block 407 near the sliding rod 410. When it is necessary to remove the bracket 401 and filter screen 3 from inside the box, pull the slide rod 410 to move it. The slide rod 410 slides on the inner wall of the connecting rail 404, and the slide rod 410 drives the connecting rod 405 to move. The connecting rod 405 drives the cover plate 414 to move, and the cover plate 414 drives the fixing frame 403 to move. The fixing frame 403 drives the bracket 401 to move outward, separating the bracket 401 from the slide frame 402. Then, hold the bracket 401 and continue to pull the cover plate 414 outward. The cover plate 414 drives the fixing frame 403 to separate from the elastic block 406 on the bracket 401. Then, move the cover plate 414 upward until it reaches the appropriate position. Pulling the connecting block 407 moves the auxiliary rod 413, causing it to slide along the inner wall of the slide rod 410. The connecting block 407 stretches the spring 412, aligning the insertion rod 411 with the slot 409. Releasing the connecting block 407 and spring 412 causes the insertion rod 411 to retract and insert into the slot 409 for fixation. When the cover plate 414 needs to be reset, the insertion rod 411 is inserted into the insertion hole 408 for fixation. The four insertion rods 411 are respectively matched with two insertion holes 408 and two slots 409. The cross-section of the insertion rod 411 is circular. The connecting block 407 is a rubber block with rounded corners. The rubber material increases friction between the hand and the connecting block 407, preventing slippage when pulling. The auxiliary rod 413 has a circular cross-section and is made of stainless steel. The auxiliary rod 413 can limit the spring 412 to prevent deformation during use and improve the service life of the spring 412. The elastic block 406 has a rectangular cross-section and is made of silicone.The elastic block 406 has a certain degree of elasticity, which allows for easy separation of the elastic block 406 from the fixed frame 403.

A positioning rod 53 is slidably connected to the inner wall of the connecting plate 51. A connecting ring 52 is rotatably connected to the arc surface of the positioning rod 53. Several locking strips 54 are fixedly connected to the arc surface of the connecting ring 52. Several slots 55 are opened on the inner wall of the connecting plate 51. The positioning rod 53 is fixedly connected to the connecting frame 2. When connecting frame 2 and housing 1 need to be connected, pull connecting frame 2 to move it. Connecting frame 2 moves positioning rod 53, positioning rod 53 moves connecting ring 52, connecting ring 52 moves locking strip 54. Then connecting ring 52 and locking strip 54 pass through connecting plate 51 and slot 55. After moving to the appropriate position, rotate connecting ring 52 to move it. Connecting ring 52 moves locking strip 54. After moving to the appropriate angle, locking strip 54 abuts against connecting plate 51. Then connecting frame 2 and housing 1 are connected and fixed. Locking strip 54 is adapted to slot 55. Locking strip 54 is made of stainless steel. Stainless steel material can increase the service life of locking strip 54 and prevent locking strip 54 from rusting during use.

[0034] The working principle of the modular box filter provided by this utility model is as follows: When it is necessary to remove the bracket 401 and filter screen 3 inside the box, pull the slide rod 410 to move it. The slide rod 410 slides on the inner wall of the connecting rail 404. The slide rod 410 drives the connecting rod 405 to move, the connecting rod 405 drives the cover plate 414 to move, the cover plate 414 drives the fixed frame 403 to move, the fixed frame 403 drives the bracket 401 to move outward, the bracket 401 separates from the slide frame 402, then hold the bracket 401 and continue to pull the cover plate 414 outward. The cover plate 414 drives the fixed frame 403 to separate from the elastic block 406 on the bracket 401. Then move the cover plate 414 upward. After moving to the appropriate position, pull the connecting block 407 to move it. 07 drives the auxiliary rod 413 to slide on the inner wall of the slide rod 410. The connecting block 407 drives the spring 412 to stretch, and then the insertion rod 411 is aligned with the slot 409. Then, the connecting block 407 is released and the spring 412 retracts, driving the insertion rod 411 to be inserted into the slot 409 for fixation. When it is necessary to reset and fix the cover plate 414, the insertion rod 411 is inserted into the insertion hole 408 for fixation. The rubber material can increase the friction between the hand and the connecting block 407 to prevent slippage when pulling the connecting block 407. The auxiliary rod 413 can limit the spring 412 to prevent deformation during use and improve the service life of the spring 412. The elastic block 406 has a certain elasticity, which can facilitate the separation of the elastic block 406 from the fixed frame 403.

[0035] When it is necessary to connect the connecting frame 2 to the housing 1, pull the connecting frame 2 to move it. The connecting frame 2 drives the positioning rod 53 to move, the positioning rod 53 drives the connecting ring 52 to move, and the connecting ring 52 drives the locking strip 54 to move. Then the connecting ring 52 and the locking strip 54 pass through the connecting plate 51 and the slot 55. After moving to the appropriate position, rotate the connecting ring 52 to move it. The connecting ring 52 drives the locking strip 54 to move. After moving to the appropriate angle, the locking strip 54 abuts against the connecting plate 51. Then the connecting frame 2 is connected and fixed to the housing 1.
