Description

Technical Field

[0001] This invention belongs to the field of air filtration technology, specifically relating to an air filter for textile workshops. Background Technology

[0002] During textile production, the air in the workshop contains a large amount of suspended particulate matter such as fiber lint and dust. These impurities not only affect product quality but also harm the health of workers. Therefore, it is usually necessary to install air filtration devices in the workshop ventilation system.

[0003] Currently, most air filters used in textile workshops employ filter screens or filter discs as filtration elements. When lint-laden air passes through the filter disc, the lint is trapped inside the filter holes or on the surface of the disc. Over time, the lint accumulates, easily causing blockages in the filter holes, leading to increased filtration resistance, reduced airflow, and significantly decreased filtration efficiency. To address this blockage problem, some existing filters incorporate cleaning devices, such as scrapers or brush rollers, to clean the surface of the filter disc. However, these methods primarily remove lint from the surface of the filter disc and are ineffective at removing lint embedded in the filter holes or attached to the hole walls, resulting in unsatisfactory cleaning results. Furthermore, some filters use reverse airflow or vibration to clean lint, but these methods are structurally complex, energy-intensive, and prone to causing lint to fly around during the cleaning process, leading to significant secondary pollution problems.

[0004] On the other hand, existing air filters in textile workshops are usually single-channel filters. When maintenance or replacement of filter elements is required, the entire filtration system must be shut down, affecting production continuity. Moreover, the installation and positioning structure of filter elements is relatively complex and inconvenient to disassemble, making daily maintenance and cleaning difficult.

[0005] Therefore, developing an air filter for textile workshops that can effectively clean lint inside the filter pores, prevent clogging, ensure filtration efficiency, and is easy to maintain has significant practical application value. Summary of the Invention

[0006] The purpose of this invention is to provide an air filter for textile workshops that has a simple structure and a reasonable design in order to solve the above-mentioned problems.

[0007] The present invention achieves the above objectives through the following technical solutions: An air filter for textile workshops includes a main pipe, with a plurality of filter canisters fixedly connected to one side of the main pipe. A drive shaft is vertically rotatably mounted at the center of the inner side of each filter canister. A drive assembly that mates with the air inlet of the filter canister is mounted on the upper end of the drive shaft. A plurality of filter discs are rotatably mounted in the middle of the drive shaft. A lint removal assembly that mates with the upper surface of the filter discs is mounted on the drive shaft. A lint loosening assembly that mates with the lower surface of the filter discs is mounted on the drive shaft.

[0008] As a further optimization of the present invention, a branch air inlet pipe is fixedly connected to the upper side of the main pipe, a branch valve is provided on the branch air inlet pipe, and the branch air inlet pipe is connected to the eccentric position of the filter tank.

[0009] As a further optimization of the present invention, the drive assembly includes a third fixing ring fixedly sleeved on the upper end of the drive shaft, and a plurality of arc-shaped plates are fixedly arranged on the outer side of the third fixing ring, the inner arc surface of the arc plate corresponding to the air outlet end of the branch air inlet pipe.

[0010] As a further optimization of the present invention, the filter disk is provided with a plurality of filter holes, and the edge of the filter disk is provided with a plurality of positioning components.

[0011] As a further optimization of the present invention, the lint removal assembly includes a first fixing ring fixedly sleeved on the drive shaft, a first horizontal shaft fixedly arranged on the outer side of the first fixing ring, the first horizontal shaft being located on the upper surface of the filter disc, a plurality of first rotating wheels rotatably sleeved on the outer side of the first horizontal shaft, and a plurality of winding hooks fixedly arranged on the outer side of each of the plurality of first rotating wheels, and when the first rotating wheels roll on the upper surface of the filter disc, the plurality of winding hooks are inserted into the filter holes.

[0012] As a further optimization of the present invention, the lint-loosening assembly includes a second fixing ring fixedly sleeved on the drive shaft, a second horizontal shaft fixedly arranged on the outer side of the second fixing ring, the second horizontal shaft being located on the lower surface of the filter disc, a plurality of second rotating wheels rotatably sleeved on the outer side of the second horizontal shaft, and a plurality of sponge columns fixedly arranged on the outer side of the plurality of second rotating wheels, and when the second rotating wheels roll on the lower surface of the filter disc, the plurality of sponge columns are inserted into the filter holes.

[0013] As a further optimization of the present invention, the positioning component includes a positioning spring fixedly disposed on the inner side of the filter disc edge, and one end of the positioning spring is fixedly connected to a positioning block that is laterally slidably disposed on the edge of the filter disc.

[0014] As a further optimization of the present invention, a filter cotton is sleeved on the lower part of the drive shaft, and a branch air outlet pipe connected to the bottom of the main pipe is fixedly connected to one side of the bottom of the filter tank, with the filter cotton located above the air inlet of the branch air outlet pipe.

[0015] As a further optimization of the present invention, the top of some of the filter tanks is provided with an opening, and the top of some of the filter tanks is connected to a sealing cap by screws.

[0016] As a further optimization of the present invention, the main pipe is a circular pipe, the upper side of the main pipe is connected to a main air inlet pipe, the lower side of the main pipe is connected to a main air outlet pipe, a first main valve is provided on one side of the main pipe, and a second main valve is provided on the other side of the main pipe.

[0017] The beneficial effects of this invention are as follows: 1. This invention, by simultaneously assembling a lint-loosening component and a lint-removing component on the drive shaft, located on the lower and upper surfaces of the filter disc respectively, allows for efficient operation. During operation, the sponge column of the lint-loosening component inserts into the filter holes from below, pushing the lint embedded inside and attached to the hole walls upwards, loosening it and exposing it at the top of the filter holes. Subsequently, the winding hook of the lint-removing component inserts into the filter holes from above, effectively removing and winding the loosened lint onto the hook. Through this coordinated action, not only is lint removed from the surface of the filter holes, but the interior of the filter holes is also thoroughly cleaned, significantly reducing the risk of filter clogging, ensuring long-term unobstructed filtration, and maintaining stable filtration efficiency.

[0018] 2. In this invention, the arc-shaped plate of the drive component is eccentrically aligned with the air outlet of the branch air inlet pipe. The kinetic energy of the filtered airflow itself blows the arc-shaped plate, causing the drive shaft to rotate automatically. This drives the lint-loosening component and the lint-removing component to work continuously. No additional power equipment such as motors is required, which reduces energy consumption and equipment costs. The invention is also reliable in operation and simple to maintain.

[0019] 3. This invention, by setting a positioning component on the edge of the filter disc and pressing the positioning block with a positioning spring, makes the filter disc stably positioned inside the filter tank, preventing the filter disc from shifting or rotating under the impact of airflow, thus ensuring the filtration effect. At the same time, a removable sealing cover is set on the top of the filter tank, which allows the filter disc to be easily removed or replaced by opening the sealing cover, making the operation convenient and reducing the difficulty of daily maintenance.

[0020] 4. This invention connects multiple filter tanks in parallel on one side of the main pipe. Each filter tank has a branch valve on its branch air inlet pipe. When a filter tank needs cleaning or replacement of its filter element, the corresponding branch valve can be closed to isolate the filter tank from the system. Other filter tanks can still work normally, achieving non-stop maintenance, ensuring the continuous operation of the ventilation system in the textile workshop, and improving production efficiency.

[0021] 5. This invention, by installing filter cotton on the lower part of the drive shaft, allows air containing lint to be initially filtered by the filter disc and then further filtered by the filter cotton, effectively intercepting fine particulate matter, improving the overall filtration accuracy and purification quality, and meeting the air quality requirements of textile workshops.

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1: As Figure 1 , Figure 2 As shown, an air filter for textile workshops includes a main pipe 1, with a plurality of filter canisters 2 fixedly connected to one side of the main pipe 1. In this embodiment, the number of filter canisters 2 is preferably set to five, but it is not limited to this and can be set according to the actual air volume and filtration requirements. The main pipe 1 is a circular pipe, with a main air inlet pipe 5 connected to the upper side of the main pipe 1 for introducing the air containing lint to be filtered from the textile workshop; and a main air outlet pipe 6 connected to the lower side of the main pipe 1 for discharging the filtered clean air. A first main valve 7 is provided on one side of the main pipe 1, and a second main valve 8 is provided on the other side, facilitating maintenance or isolation operations of the main pipe 1.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the top of the filter tank 2 has an opening, and a sealing cover 9 is connected to the top of the filter tank 2 by screws. After opening the sealing cover 9, the filter element inside the filter tank 2 can be replaced or cleaned. A branch air inlet pipe 3 is fixedly connected to the upper side of the main pipe 1. A branch valve 4 is installed on the branch air inlet pipe 3. The branch air inlet pipe 3 is connected to the filter tank 2 at an eccentric position, that is, the air outlet end of the branch air inlet pipe 3 is offset from the central axis of the filter tank 2, so as to drive the internal parts of the subsequent drive assembly 16 to rotate. One side of the bottom of the filter tank 2 is fixedly connected to a branch air outlet pipe 10 that is connected to the bottom of the main pipe 1. A valve is installed on the branch air outlet pipe 10. The filtered air enters the bottom of the main pipe 1 from the branch air outlet pipe 10 and is discharged. Multiple filter tanks 2 are connected in parallel through one side of the main pipe 1. Since each filter tank 2 has a branch air inlet pipe 3 equipped with a branch valve 4, when a filter tank 2 needs to be cleaned or the filter element replaced, the corresponding branch valve 4 can be closed to isolate the filter tank 2 from the system. Other filter tanks 2 can still work normally, realizing maintenance without stopping the machine, ensuring the continuous operation of the ventilation system in the textile workshop, and improving production efficiency.

[0027] like Figure 1 , Figure 2 As shown, a drive shaft 11 is vertically rotatably mounted on the inner center of several filter canisters 2. Bearings are fixedly mounted on the inner bottom of the filter canisters 2 and the inner lower surface of the sealing cover 9. The upper and lower ends of the drive shaft 11 are respectively rotatably inserted between the two bearings. Filter cotton 12 is sleeved on the lower part of the drive shaft 11, and several filter discs 13 are rotatably mounted on the middle of the drive shaft 11. The filter cotton 12 is located above the air inlet of the branch air outlet duct 10 and is used to perform secondary fine filtration on the air after the initial filtration by the filter discs 13, intercepting fine particulate matter. After the air containing lint is initially filtered by the filter discs 13, it is further filtered by the filter cotton 12, effectively intercepting fine particulate matter, improving the overall filtration accuracy and purification quality, and meeting the air quality requirements of the textile workshop.

[0028] like Figure 1 , Figure 2 , Figure 4 As shown, the number of filter discs 13 can be set to one or more according to the filtration accuracy requirements. In this embodiment, each filter tank 2 is provided with two filter discs 13, which are distributed vertically at intervals. Several filter holes 17 are opened on the filter discs 13, and the diameter of the filter holes 17 is set according to the range of lint particle size in the textile workshop. Several positioning components 18 are provided on the edge of the filter discs 13 for detachably fixing the filter discs 13 to the inner wall of the filter tank 2.

[0029] Specifically, such as Figure 7 As shown, the positioning assembly 18 includes a positioning spring 1802 fixedly disposed on the inner side of the edge of the filter disc 13. One end of the positioning spring 1802 is fixedly connected to a positioning block 1801 that is laterally slidably disposed on the edge of the filter disc 13. One end of the positioning block 1801 is provided with an arc, which facilitates the positioning block 1801 to slide into and out of the positioning groove on the inner wall of the filter tank 2. During installation, the filter disc 13 is placed into the filter tank 2. Under the elastic force of the positioning spring 1802, the positioning block 1801 extends outward and is engaged in the corresponding positioning groove (not shown in the figure) on the inner wall of the filter tank 2, thereby achieving axial and circumferential positioning of the filter disc 13 and preventing the filter disc 13 from shifting or rotating under the impact of airflow. When it is necessary to remove the filter disc 13, simply pull the drive shaft 11 upward, thereby moving the positioning block 1801 upward, so that the positioning block 1801 is squeezed and slid into the inner side of the filter disc 13, causing it to disengage from the positioning groove, and the filter disc 13 can be pulled out upward.

[0030] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the drive shaft 11 is equipped with a lint removal assembly 14 that mates with the upper surface of the filter disc 13, and a lint loosening assembly 15 that mates with the lower surface of the filter disc 13. For each filter disc 13, a set of lint removal assemblies 14 and a set of lint loosening assemblies 15 are provided.

[0031] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, the lint removal assembly 14 includes a first fixing ring 1401 fixedly sleeved on the drive shaft 11. The first fixing ring 1401 is fixedly connected to the drive shaft 11 by screws and rotates synchronously with the drive shaft 11. A first horizontal shaft 1402 is fixedly installed on the outer side of the first fixing ring 1401. The first horizontal shaft 1402 extends along the radial direction of the filter disk 13 and is located above the upper surface of the filter disk 13. A plurality of first rotating wheels 1403 are rotatably sleeved on the outer side of the first horizontal shaft 1402. The plurality of first rotating wheels 1403 are arranged at intervals along the length direction of the first horizontal shaft 1402, and the interval distance matches the hole spacing of the filter holes 17 on the filter disk 13. A plurality of winding hooks 1404 are fixedly installed on the outer side of each of the plurality of first rotating wheels 1403. The hook ends of the winding hooks 1404 are in the same direction of rotation as the first rotating wheels 1403. The winding hooks 1404 are made of thin metal hooks or hard plastic hooks, and the hook bodies are curved to facilitate hooking lint.

[0032] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the lint-loosening assembly 15 includes a second fixing ring 1501 fixedly sleeved on the drive shaft 11. A second horizontal shaft 1502 is fixedly disposed on the outer side of the second fixing ring 1501, and the second horizontal shaft 1502 is located below the lower surface of the filter disc 13. A plurality of second rotating wheels 1503 are rotatably sleeved on the outer side of the second horizontal shaft 1502, and a plurality of sponge columns 1504 are fixedly disposed on the outer side of the plurality of second rotating wheels 1503. The sponge columns 1504 are preferably made of polyurethane sponge material, which has appropriate elasticity and flexibility, and can be inserted into the inner wall of the filter hole 17 for cleaning without damaging the edge of the filter hole 17. The sponge columns 1504 of the lint-loosening assembly 15 are inserted into the filter hole 17 from below, pushing the lint embedded in the filter hole 17 and attached to the hole wall from bottom to top, so that the lint is loosened and exposed at the upper end of the filter hole 17. Then, the winding hook 1404 of the lint-removing assembly 14 is inserted into the filter hole 17 from above, effectively removing the loose lint and winding it around the winding hook 1404. Through the coordinated action of the upper and lower parts, not only can the lint on the surface of the filter hole 17 be removed, but the interior of the filter hole 17 can also be thoroughly cleaned, significantly reducing the risk of clogging of the filter hole 17, ensuring long-term unobstructed filtration channels, and maintaining stable filtration efficiency.

[0033] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a drive assembly 16 that mates with the air inlet of the filter tank 2 is provided at the upper end of the drive shaft 11. The drive assembly 16 includes a third fixing ring 1601 fixedly sleeved on the upper end of the drive shaft 11. Several arc-shaped plates 1602 are fixedly arranged on the outer side of the third fixing ring 1601. The number of arc-shaped plates 1602 is preferably 4 to 6, and they are evenly distributed along the circumference of the third fixing ring 1601. The inner arc surface of the arc-shaped plate 1602 corresponds to the air outlet end of the branch air inlet pipe 3. The air outlet end of the branch air inlet pipe 3 eccentrically blows the inner arc surface of the arc-shaped plate 1602. When lint-laden air is blown into the filter tank 2 at high speed from the branch air inlet pipe 3, the airflow impacts the inner arc surface of the arc plate 1602. Under the action of the eccentric impact force, the arc plate 1602 drives the third fixed ring 1601 to rotate, which in turn drives the drive shaft 11 to rotate, thereby driving the lint-loosening component 15 and the lint-removing component 14 to work continuously. No additional power equipment such as motors is required, which reduces energy consumption and equipment costs. Moreover, it is reliable in operation and simple to maintain.

[0034] It should be noted that, in use, this type of air filter for textile workshops involves the following steps: First, the lint-laden air from the textile workshop enters the main pipe 1 through the main air inlet pipe 5. The first main valve 7 and the second main valve 8 are closed, and the branch valve 4 is opened. The lint-laden air then enters the filter canister 2 eccentrically through the branch air inlet pipe 3. During the process of entering the filter canister 2, the high-speed airflow first impacts the inner arc surface of the arc plate 1602 of the drive assembly 16. Because the air outlet of the branch air inlet pipe 3 is eccentrically positioned with respect to the filter canister 2, the airflow generates a tangential impact force on the arc plate 1602, driving the third fixing ring 1601 to continuously rotate the drive shaft 11. Subsequently, the lint-laden air flows downward and passes through the filter holes 17 of several filter discs 13 in sequence. As the air passes through the filter holes 17, the lint is trapped inside the filter holes 17 or adheres to the upper surface of the filter discs 13; Meanwhile, the rotation of the drive shaft 11 drives the first fixed ring 1401 and the second fixed ring 1501 to rotate synchronously. The second fixed ring 1501 drives the second horizontal shaft 1502 to revolve around the drive shaft 11, and the drive shaft 11 drives the second rotating wheel 1503 to roll along the lower surface of the filter disc 13. During the rolling process, the sponge columns 1504 on the outer side of the second rotating wheel 1503 are inserted into the corresponding filter holes 17 in sequence. The sponge columns 1504 enter from the bottom of the filter holes 17, pushing the lint accumulated or attached to the hole walls inside the filter holes 17 from the bottom to the top, so that the lint is loosened and partially exposed at the top of the filter holes 17; at the same time, the sponge columns 1504 generate friction with the inner wall of the filter holes 17 during insertion and withdrawal, wiping away the fine lint and dust attached to the hole walls, thus cleaning the inner wall of the filter holes 17; Next, the first fixing ring 1401 revolves around the drive shaft 11, which in turn drives the first rotating wheel 1403 to roll along the upper surface of the filter disc 13. During the rolling process, the winding hook 1404 on the outer side of the first rotating wheel 1403 inserts into the corresponding filter hole 17. Since the lint in the filter hole 17 has been loosened by the sponge column 1504 and partially exposed at the top, the winding hook 1404 can easily hook the lint and pull it out of the filter hole 17 as it rotates with the first rotating wheel 1403, causing the lint to wrap around the winding hook 1404. As the drive shaft 11 continues to rotate, the amount of lint wrapped around the winding hook 1404 gradually increases. When cleaning is required, the sealing cover 9 is opened, and the lint removal component 14 is removed or the lint on the winding hook 1404 is directly removed. The air filtered by filter disc 13 continues to flow downwards, passing through filter cotton 12. Filter cotton 12 further intercepts tiny particles in the air, purifying the air even more. Finally, the purified air enters the bottom of main duct 1 from branch air outlet duct 10, and is discharged to the workshop or exhaust system through main air outlet duct 6. When a filter canister 2 needs maintenance or cleaning, the corresponding branch valve 4 can be closed to cut off the air intake of that filter canister 2, while the other filter canisters 2 continue to operate normally, achieving online maintenance without shutting down the system.

[0035] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
