Description

Technical Field

[0001] This utility model belongs to the field of filtration-related technology, and in particular relates to an air filter with adjustable filtration cycles. Background Technology

[0002] An air filter is an air filtration device, generally used in cleanrooms, clean factories, laboratories, and clean rooms, or for dust prevention in electronic, mechanical, and communication equipment. It is also widely used in the automotive and fluid machinery industries (air compressors, vacuum pumps, fans, etc.) to separate liquid water and oil droplets from compressed air and filter out dust and solid impurities, ensuring the normal operation of equipment. Filters adjust the number of filtration layers by the number of filter media layers inside; however, some filters only have a single-layer filtration effect, and these air filters still have the following drawbacks in practical use:

[0003] Adjusting the filtration frequency of an air filter is primarily about finding the optimal balance between filtration effectiveness, energy consumption, and equipment lifespan. For example, a meeting room with many people needs a higher filtration frequency, while a less crowded room requires a lower frequency. Hospital operating rooms have different requirements than regular wards; operating rooms need cleaner air and therefore require a higher filtration frequency. However, most filters have a fixed filtration frequency, meaning you can choose a filter with the appropriate frequency for the specific location, but you can't adjust the filtration frequency when needed, making them limited in functionality.

[0004] Secondly, the filtration section, i.e. the filter media, needs to be replaced regularly. Although the filter media in most filters can be replaced, such as replacing some filter cartridges, it is troublesome to replace aluminum materials on top of the adjustable filtration cycle, so it needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide an air filter with an adjustable filtration frequency. By setting up a partition, mounting frame, adjustment frame, filter assembly, filter channel, and screw, it solves the problems of filter replacement being inconvenient when the filter cannot adjust the filtration frequency and the filter media position inside the filter can be adjusted.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an air filter with adjustable filtration times, including a filter channel, a mounting frame, a partition, an adjustment frame, and a filter assembly. The filter channel is arranged in a side U-shape. Vertical and equidistantly distributed mounting frames are fixed inside the filter channel. A partition is fixed in the middle of both sides of each mounting frame, and the partition is fixedly connected to the inner wall of the filter channel. A screw is vertically rotatably connected inside the filter channel on one side of each mounting frame. A side plate is fixed to the opening of the filter channel by bolts.

[0008] An adjustment frame is vertically and movably connected within the mounting frame, and a filter component is inserted and fixed within the adjustment frame.

[0009] Furthermore, the upper half of both ends of the filter channel is fixed with a sealing plate, and the two ends of the filter channel below the two sealing plates are respectively fixed with an air inlet and an air outlet. A screw is provided on the side of each mounting frame facing the air outlet. The bottom of the opposite side of the two sealing plates is fixed with the two outermost partitions, and the upper ends of the opposite side of the air inlet and air outlet are also fixed with the two outermost partitions.

[0010] Furthermore, the top of the filter channel is fixed with equidistantly distributed rotor motors, and each screw is equipped with a rotor motor, the output shaft of which is fixedly connected to the top of the screw below it.

[0011] Furthermore, symmetrically distributed limiting grooves are provided on both inner walls of the mounting frame, and two limiting blocks are fixed at the upper and lower ends of both sides of the adjustment frame, with the limiting blocks slidably disposed in the limiting grooves; sealing gaskets are fixed at both the upper and lower ends of the adjustment frame.

[0012] Furthermore, the upper and lower ends of the adjustment frame near the screw are both fixed with threaded sleeves, and the threaded sleeves are threadedly connected to the screw near them.

[0013] Furthermore, the filter assembly includes a filter frame and a pressure cap, both of which are fixed with stainless steel wire mesh, and filter cotton is provided in the filter frame between the two stainless steel wire meshes.

[0014] Furthermore, the adjustment frame is provided with a mounting groove and a recess, and the mounting groove and the recess are connected. The filter frame is inserted into the mounting groove, and the frame edge and the pressure cap of the filter frame are in contact with each other and placed in the recess before being screwed into the adjustment frame for fixation.

[0015] This utility model has the following beneficial effects:

[0016] This invention solves the problem of adjustable filtration cycles by incorporating a partition, mounting frames, adjusting frames, filter components, a filter channel, and a screw. The filter channel is installed in the ventilation section, connected to external air via an inlet and to the interior via an outlet (the exhaust fan is omitted). Five mounting frames are installed within the filter channel, each containing an adjusting frame and a filter component, allowing for a maximum of five filtration cycles. Custom sizes and quantities can be added as needed. Air enters through the inlet and exits through the outlet. Adjusting the filtration cycle is achieved by controlling a corresponding rotor motor, which drives the screw to rotate. The forward and reverse rotation of the rotor motor controls the screw's rotation direction, thus controlling the raising and lowering of the adjusting frames. Each adjusting frame contains a filter component. Unnecessary filter components and adjusting frames are moved to the top of the partition, while needed components and frames are moved to the bottom of the partition, aligning with the inlet and outlet, thereby changing the filtration cycle.

[0017] This invention solves the problem of inconvenient filter media replacement when the position of the filter media inside the filter is adjustable by setting an adjustment frame and a filter assembly. The filter assembly and the adjustment frame are detachable. The position of the filter assembly can be changed by changing the position of the adjustment frame. In the filter assembly, first insert the filter cotton into the filter frame, then cover it with the pressure cap. The two ends of the filter cotton are blocked by stainless steel wire mesh to prevent it from falling out. Then, embed the filter assembly into the mounting groove and recess in the adjustment frame. Finally, screws are inserted through the four corners of the filter frame and the pressure cap and screwed into the adjustment frame for fixation. The side panel can be removed for disassembly.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Please see Figure 1-8 As shown, this utility model is an air filter with adjustable filtration times, including a filter channel 1, a mounting frame 2, a partition 3, an adjusting frame 4, and a filter assembly 5. The filter channel 1 is U-shaped on the side. Vertically and equally spaced mounting frames 2 are fixed inside the filter channel 1. A partition 3 is fixed to the middle of both sides of each mounting frame 2, and the partition 3 is fixedly connected to the inner wall of the filter channel 1. A screw 105 is vertically rotatably connected to the filter channel 1 on one side of each mounting frame 2. A side plate 104 is fixed to the opening of the filter channel 1 by bolts. An adjusting frame 4 is vertically movably connected inside the mounting frame 2, and a filter assembly 5 is inserted and fixed inside the adjusting frame 4.

[0031] The filter channel 1 serves as the outer shell of the filter and, when fixed with the side plate 104, forms a square frame structure. The filter channel 1 is installed in the ventilation section. Five mounting frames 2 are set inside the filter channel 1. Each mounting frame 2 is equipped with an adjustment frame 4 and a filter assembly 5, which can filter up to five times. The size and quantity can also be customized according to actual needs. The upper and lower parts of the mounting frame 2 are separated by a horizontal partition 3. The upper area is not in operation, and the lower area is used as a filter flow channel. The air to be filtered passes through the lower part of the partition 3. The height position of the adjustment frame 4 and its internal filter assembly 5 can be changed by rotating the screw 105.

[0032] The upper half of both ends of the filter channel 1 is fixed with a sealing plate 102, and the two ends of the filter channel 1 below the two sealing plates 102 are respectively fixed with an air inlet 103 and an air outlet 106. A screw 105 is provided on the side of each mounting frame 2 facing the air outlet 106. The bottom of the opposite side of the two sealing plates 102 is fixed with the two outermost partition plates 3, and the upper ends of the opposite side of the air inlet 103 and the air outlet 106 are also fixed with the two outermost partition plates 3.

[0033] The upper part of the two ports of the filter channel 1 is sealed by the sealing plate 102 to prevent air from overflowing. The lower part of the two ports of the filter channel 1 is equipped with an air inlet 103 and an air outlet 106 for air intake and exhaust. Air enters through the air inlet 103 and is exhausted towards the air outlet 106.

[0034] The top of the filter channel 1 is fixed with equidistantly distributed rotor motors 101, and each screw 105 is provided with a rotor motor 101 above it. The output shaft of the rotor motor 101 is fixedly connected to the top of the screw 105 below it.

[0035] The upper and lower ends of the adjusting frame 4 near the screw 105 are both fixed with threaded sleeves 404, and the threaded sleeves 404 are threadedly connected to the screw 105 near them.

[0036] By controlling the operation of the corresponding rotor motor 101, the screw 105 is driven to rotate. The forward and reverse rotation of the rotor motor 101 controls the rotation direction of the screw 105, which is matched with the threaded connection of the threaded sleeve 404. The adjusting frame 4 is limited in the limiting groove 201 by the limiting block 402, thereby controlling the lifting and lowering of the adjusting frame 4, which can only move linearly along the limiting groove 201.

[0037] The two inner walls of the mounting frame 2 are provided with symmetrically distributed limiting grooves 201. The upper and lower ends of both sides of the adjusting frame 4 are fixed with two limiting blocks 402, which are slidably disposed in the limiting grooves 201. The upper and lower ends of the adjusting frame 4 are fixed with sealing gaskets 401.

[0038] The limiting block 402 is slidably set in the limiting groove 201 to restrict the movement of the adjusting frame 4, so that it cannot rotate and can only move up and down. Secondly, the setting of the sealing gasket 401 means that when the adjusting frame 4 moves to the upper layer of the partition 3, the sealing gasket 401 below the adjusting frame 4 will prevent the air below the partition 3 from entering the upper layer of the partition 3, and when the adjusting frame 4 moves to the lower layer, the sealing gasket 401 above the adjusting frame 4 will also prevent the air from entering the upper layer of the partition 3.

[0039] The filter assembly 5 includes a filter frame 502 and a cover 501. Stainless steel wire mesh 503 is fixed inside both the filter frame 502 and the cover 501, and filter cotton 504 is provided inside the filter frame 502 between the two stainless steel wire meshes 503.

[0040] An installation groove 403 and a recess 4031 are provided through the adjustment frame 4, and the installation groove 403 and the recess 4031 are connected. The filter frame 502 is inserted into the installation groove 403. The frame edge of the filter frame 502 and the pressure cover 501 are in contact with each other and placed in the recess 4031. Then, screws are screwed into the adjustment frame 4 for fixation.

[0041] When installing the filter assembly 5, first insert the filter cotton 504 into the filter frame 502, then cover it with the pressure cap 501. The two ends of the filter cotton 504 are blocked by the stainless steel wire mesh 503 and will not fall off. Then, embed the filter assembly 5 into the mounting groove 403 and the recess 4031 in the adjusting frame 4. Finally, insert screws through the four corners of the filter frame 502 and the pressure cap 501 and screw them into the adjusting frame 4 to fix them.

[0042] The specific working principle of this utility model is as follows: First, install the filter assembly 5 into the adjustment frame 4. First, insert the filter cotton 504 into the filter frame 502, and then cover it with the pressure cover 501. At this time, the two ends of the filter cotton 504 are blocked by the stainless steel wire mesh 503 inside the filter frame 502 and the pressure cover 501. Then, embed the filter assembly 5 into the mounting groove 403 and the recess 4031 inside the adjustment frame 4. Finally, insert screws through the four corners of the filter frame 502 and the pressure cover 501 and screw them into the adjustment frame 4 to fix them. Repeat this process to fix all the filter assemblies 5. Alternatively, the filter assembly 5 can be disassembled and replaced in the reverse order.

[0043] Subsequently, the side plate 104 is closed. At this time, five mounting frames 2 are set in the filter channel 1. Each mounting frame 2 is equipped with an adjustment frame 4 and a filter assembly 5, which can filter up to five times. The upper and lower parts of the mounting frame 2 are separated by a horizontal partition 3. The upper area does not work, and the lower area is used as a filter flow channel. Air enters from the air inlet 103 and is discharged towards the air outlet 106. When the number of filtrations needs to be adjusted, the corresponding rotor motor 101 is controlled to work, driving the screw 105 to rotate. The forward and reverse rotation of the rotor motor 101 controls the rotation direction of the screw 105, which is connected to the threaded sleeve 404. The adjustment frame 4 is limited in the limit groove 201 by the limit block 402, thereby controlling the rise and fall of the adjustment frame 4. It can only move linearly along the limit groove 201. Adjusting an appropriate number of adjustment frames 4 to move down below the partition 3 controls the corresponding number of filtrations.

[0044] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
