Description

Technical Field

[0001] This utility model relates to the field of air filtration technology, specifically a multi-stage air filtration device based on graded filters and high-efficiency filter elements. Background Technology

[0002] A multi-stage air filtration device is a device that uses an orderly combination of multiple layers of filter components with different functions to purify air pollutants in stages, by particle size, and by type. Based on the combination of graded filters and high-efficiency filter elements, a multi-stage air filtration device uses a multi-level filter component design to intercept and purify pollutants such as dust, particulate matter, microorganisms, and harmful gases in the air layer by layer. By utilizing the differences in pore size, material properties, and functional division of different filter levels, it can achieve graded filtration and precise purification of air pollutants, improve air cleanliness, and is suitable for scenarios with high air quality requirements such as medical, industrial, laboratory, and indoor environmental management.

[0003] When using a multi-stage air filtration system, the filter elements need to be replaced after a long period of use. However, the existing multi-stage air filtration system's filter elements are not easy to disassemble and install quickly, making filter replacement inconvenient.

[0004] Therefore, we propose a multi-stage air filtration device based on graded filters and high-efficiency filter elements that allows for quick disassembly and assembly of filter components, making replacement more convenient. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage air filtration device based on graded filters and high-efficiency filter elements to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage air filtration device based on graded filter screens and high-efficiency filter elements, including a filter tube, a support leg fixedly installed on the outer wall of the filter tube, an air outlet frame connected to the end of the filter tube, and a processing component disposed on the side of the air outlet frame near the filter tube, the processing component including a disassembly and assembly component disposed on the side of the air outlet frame, and a cleaning component disposed on the side of the disassembly and assembly component away from the air outlet frame.

[0007] Preferably, the assembly includes a filter frame slidably disposed inside the filter tube, a filter element fixedly installed inside the filter frame, a groove opened on the top surface of the filter tube, a first magnetic ring fixedly installed on the inner wall of the groove, a second magnetic ring slidably disposed inside the groove, a locking pin fixedly installed on the side wall of the second magnetic ring, a central column fixedly installed on the top surface of the filter tube, and a locking plate rotatably connected to the outer wall of the central column.

[0008] Preferably, the cleaning assembly includes a suction pump box fixedly installed at the end of the filter tube away from the air outlet frame. An air inlet frame is connected to the outer wall of the suction pump box. A vertical plate is fixedly installed on the outer wall of the air inlet frame. A limit rod is fixedly installed on the side wall of the vertical plate. A collar is slidably provided on the outer wall of the limit rod. A sliding frame is fixedly installed on the outer wall of the collar. A brush is fixedly installed on the inner side of the sliding frame.

[0009] Preferably, the second magnetic ring and the first magnetic ring are magnetically repulsive, and the outer wall of the locking pin is engaged with the inside of the locking plate. Under the constraint of magnetic repulsion, the locking pin and the locking plate can be stably engaged.

[0010] Preferably, the filter element consists of a filter screen and a filter core, and there are three sets of filter frames, which are equidistantly distributed inside the filter tube. Under the constraint of the filter element, air can be filtered.

[0011] Preferably, the inner side of the sliding frame is slidably disposed with the outer wall of the air intake frame, and the brush is a soft brush body. Under the sliding restriction of the sliding frame, it drives the brush to slide accordingly to clean the air intake frame.

[0012] Preferably, there are two limiting rods, which are symmetrically distributed around the center line of the air intake frame. Under the restriction of the limiting rods, the sliding frame can slide stably.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This multi-stage air filtration device, based on graded filters and high-efficiency filter elements, consists of a detachable assembly. When filtering air, the suction pump box is activated, drawing air into the filter tube. The air is then filtered through the filter elements, which consist of a filter screen and a filter element. Under the constraint of the filter screen, particles of varying sizes can be precisely intercepted, effectively filtering everything from large dust particles to tiny particles, achieving deep purification. The filter element is made of high-efficiency polyethylene material, characterized by high filtration efficiency and low resistance, thus enhancing air purification. Because the filter screen pore size decreases as it is distributed inside the filter tube, multi-stage filtration is achieved, enabling the filtration of particles of different sizes. As the filter elements are used over time, they require maintenance. For periodic replacement, press the locking pin downwards to cause the second magnetic ring to slide into the groove. At this point, the outer wall of the locking pin is no longer engaged with the locking hole inside the locking plate. Rotate the locking plate so that it rotates around the point of rotation with the central column. The locking plate is no longer engaged with the outer wall of the filter frame. Remove the filter frame from the filter tube to replace the filter frame and filter element. Insert the new filter frame and filter element into the filter tube and rotate the locking plate so that it engages with the outer wall of the filter frame. At this point, the locking pin is no longer squeezed by the bottom of the locking plate. Under the magnetic repulsion between the second and first magnetic rings, push the second magnetic ring and the locking pin outwards from the groove to engage the locking pin with the locking plate, preventing the locking plate from rotating. This structure can efficiently filter air, and the filter element can be easily disassembled, making the filtration work simpler.

[0015] 2. This multi-stage air filtration device based on graded filters and high-efficiency filter elements consists of a cleaning component. When filtering air, the suction pump box is activated, which delivers outside air into the filter tube through the air inlet frame. The air is filtered by the disassembly and assembly components, and then discharged through the air outlet frame. Under the restriction of the air inlet frame, the air entering the suction pump box can be initially filtered to prevent impurities from clogging the suction pump box. When impurities adhere to the outer wall of the air inlet frame, the sliding frame is pulled, causing the collar fixed at its end to slide on the outer wall of the limiting rod. The sliding frame drives the brush to clean the impurities adhering to the outer wall of the air inlet frame. This structure can pre-treat the air entering the suction pump box and prevent large impurities from clogging the suction pump box. Attached Figure Description

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of the multi-stage air filtration device based on graded filters and high-efficiency filter elements provided by this utility model is as follows: Figures 1 to 6 As shown: A multi-stage air filtration device based on graded filter screens and high-efficiency filter elements, including filter tube 1;

[0025] The outer wall of filter tube 1 is fixedly equipped with support legs 2;

[0026] An air outlet frame 3 is connected to the end of the filter tube 1;

[0027] The processing component 4 is located on the side of the air outlet frame 3 near the filter tube 1. The processing component 4 includes a disassembly and assembly component 41 located on the side of the air outlet frame 3. The disassembly and assembly component 41 includes a filter frame 411 that is slidably disposed inside the filter tube 1. A filter element 412 is fixedly installed inside the filter frame 411. A sliding groove 413 is opened on the top surface of the filter tube 1. A first magnetic ring 414 is fixedly installed on the inner wall of the sliding groove 413. A second magnetic ring 415 is slidably disposed inside the sliding groove 413. A locking pin 416 is fixedly installed on the side wall of the second magnetic ring 415. A central column 417 is fixedly installed on the top surface of the filter tube 1. A locking plate 418 is rotatably connected to the outer wall of the central column 417.

[0028] In this embodiment, when filtering air, the suction pump box 421 is activated, drawing air into the filter tube 1. The air is then filtered through the filter element 412, which consists of a filter screen and a filter core. Under the constraint of the filter screen, particles of varying sizes can be precisely intercepted, effectively filtering everything from large dust particles to tiny particles, achieving deep purification. The filter core is made of high-efficiency polyethylene-based material, characterized by high filtration efficiency and low resistance, thus enhancing air purification. Because the filter screen pores are distributed from large to small within the filter tube 1, multi-stage filtration is possible, allowing for the filtration of particles of different sizes. As the filter element 412 is used over time, it needs to be replaced periodically. Pressing the locking pin 416 downwards causes the second magnetic ring 415 to slide into the groove 413. At this point, the outer wall of the locking pin 416 is no longer in contact with the groove. The locking holes inside the locking plate 418 engage the filter. By rotating the locking plate 418, it rotates around the point of rotational connection with the central column 417. The locking plate 418 is no longer engaged with the outer wall of the filter frame 411. The filter frame 411 can be removed from the filter tube 1, allowing the filter frame 411 and filter element 412 to be replaced. The new filter frame 411 and filter element 412 are inserted into the filter tube 1. The locking plate 418 is rotated, engaging with the outer wall of the filter frame 411. At this time, the locking pin 416 is no longer squeezed by the bottom of the locking plate 418. Under the magnetic repulsion between the second magnetic ring 415 and the first magnetic ring 414, the second magnetic ring 415 and the locking pin 416 are pushed towards the outside of the slide groove 413, causing the locking pin 416 to engage with the locking plate 418, preventing the locking plate 418 from rotating. This structure can efficiently filter air, and the filter element 412 can be easily disassembled, making the filtration work simpler.

[0029] Furthermore, the second magnetic ring 415 and the first magnetic ring 414 are magnetically repelled, and the outer wall of the locking pin 416 is locked to the inside of the locking plate 418. Under the restriction of magnetic repulsion, the locking pin 416 and the locking plate 418 can be stably locked together.

[0030] Furthermore, the filter element 412 consists of a filter screen and a filter core, and there are three sets of filter frames 411, which are equidistantly distributed inside the filter tube 1. Under the constraint of the filter element 412, air can be filtered.

[0031] Example 2: Based on Example 1, a preferred embodiment of the multi-stage air filtration device based on graded filters and high-efficiency filter elements provided by this utility model is as follows: Figures 1 to 6As shown: The cleaning component 42 includes a suction pump box 421 fixedly installed at the end of the filter tube 1 away from the air outlet frame 3. An air inlet frame 422 is connected to the outer wall of the suction pump box 421. A vertical plate 423 is fixedly installed on the outer wall of the air inlet frame 422. A limit rod 424 is fixedly installed on the side wall of the vertical plate 423. A collar 425 is slidably provided on the outer wall of the limit rod 424. A sliding frame 426 is fixedly installed on the outer wall of the collar 425. A brush 427 is fixedly installed on the inner side of the sliding frame 426.

[0032] In this embodiment, when air is filtered, the suction pump box 421 is activated, which delivers outside air into the filter tube 1 through the air inlet frame 422. The air is filtered through the disassembly and assembly assembly 41 and then discharged through the air outlet frame 3. Under the restriction of the air inlet frame 422, the air entering the suction pump box 421 can be initially filtered to prevent impurities from clogging the inside of the suction pump box 421. When impurities are attached to the outer wall of the air inlet frame 422, the sliding frame 426 is pulled so that the collar 425 fixedly installed at its end slides on the outer wall of the limiting rod 424. The sliding frame 426 drives the brush 427 to clean the impurities attached to the outer wall of the air inlet frame 422. This structure can pre-treat the air entering the suction pump box 421 and prevent large impurities from clogging the suction pump box 421.

[0033] Furthermore, the inner side of the sliding frame 426 is slidably disposed with the outer wall of the air intake frame 422, and the brush 427 is a soft brush body. Under the sliding restriction of the sliding frame 426, it drives the brush 427 to slide accordingly, cleaning the air intake frame 422.

[0034] In addition, there are two limit rods 424, which are symmetrically distributed around the center line of the air intake frame 422. Under the restriction of the limit rods 424, the sliding frame 426 can slide stably.

[0035] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
