[0037] The following will clearly and completely describe the technical solutions of this application in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] The following combination Figure 1 , describing the vibrating dust removal and self-cleaning air coarse-effect filtration device provided in the embodiments of the present application.

[0039] Reference Figure 1 As shown, the vibration dust removal self-cleaning air coarse filter device provided in the embodiment of the present application includes a frame 1, a first material roller 2, a second material roller 3, a filter element 4 and a cleaning assembly. The first material roller 2 is installed at the upper end of the frame 1, and the second material roller 3 is installed at the lower end of the frame 1, and the first material roller 2 is parallel to the second material roller 3. The filter element 4 is wound on the first material roller 2 / the second material roller 3, and the free end of the filter element 4 is correspondingly wound on the second material roller 3 / the first material roller 2. For example, the filter element 4 is wound on the first material roller 2, and the free end of the filter element 4 is correspondingly wound on the second material roller 3. The filter element 4 is a filter screen or filter material. Specifically, the filter element 4 is a G3-G4 grade filter material or a stainless steel metal filter screen. It can filter out dust particles with a particle size of 10μm or more in the air environment. The cleaning assembly is arranged on the frame 1, located on at least one side of the filter element 4, and is used to collect dust accumulated on the windward surface of the filter element 4.

[0040] Utilizing the technical solution provided by the above embodiment, by providing a first material roller 2 and a second material roller 3, the filter element 4 is wound around one of the first material roller 2 or the second material roller 3, and the free end of the filter element 4 is wound around the other of the first material roller 2 or the second material roller 3. By rotating one of the first material roller 2 or the second material roller 3, the filter surface of the filter element 4 can be adjusted to prevent dust accumulation on the filter surface, thereby ensuring that the filter element 4 always maintains a high filtration efficiency. Furthermore, the filter material or filter screen structure can be recycled, solving the problems of difficult and high labor costs in filter material or filter screen replacement and maintenance. A cleaning assembly is used to achieve regular and centralized cleaning of dirt, reducing the impact of the equipment on the on-site environment and reducing labor maintenance costs.

[0041] In some embodiments of the present application, the cleaning assembly includes a negative pressure head 5, a flexible hose 6, and an industrial vacuum cleaner main unit 7. The negative pressure head 5 is mounted on the frame 1, near the windward side of the filter element 4, and is used to absorb dust accumulated on the windward side of the filter element 4. One end of the flexible hose 6 is connected to the negative pressure head 5, and the other end of the flexible hose 6 is connected to the industrial vacuum cleaner main unit 7. The industrial vacuum cleaner main unit 7 can achieve regular and centralized absorption of dirt on the filter material or filter screen.

[0042] In some embodiments of the present application, the cleaning component also includes a vibration motor 8, which is installed on the frame 1, located near the leeward side of the filter element 4, and opposite to the negative pressure head 5. The vibration motor 8 shakes off the dust accumulated on the windward side of the filter element 4 by generating vibrating contact with the filter element 4.

[0043] In some embodiments of the present application, the filter element can be vibrated by a crank-connecting rod vibration mechanism, an eccentric shaft / eccentric block vibration mechanism, an elastic vibration mechanism, a cam vibration mechanism, or other vibration mechanisms to shake off the accumulated dust on the windward surface of the filter element 4.

[0044] In some embodiments of the present application, the cleaning assembly further includes a guide rail, a first screw rod 9, and a second screw rod 10. The guide rail is mounted on the frame 1, parallel to the first material roller 2, and the negative pressure head 5 and the vibration motor 8 are respectively slidably engaged with the guide rail; the first screw rod 9 is mounted on the frame 1, the first screw rod 9 is threadedly connected to the negative pressure head 5, and the first screw rod 9 drives the negative pressure head 5 to move axially thereof by self-rotation; the second screw rod 10 is mounted on the frame 1, the second screw rod 10 is threadedly connected to the vibration motor 8, and the second screw rod 10 drives the vibration motor 8 to move axially thereof by self-rotation.

[0045] In some embodiments of the present application, the vibrating dust removal, self-cleaning, coarse-effect air filter device further includes a first guide roller 11 and a second guide roller 12. The first guide roller 11 is disposed on the frame 1, adjacent to and parallel to the first material roller 2; the second guide roller 12 is disposed on the frame 1, adjacent to and parallel to the second material roller 3. The first and second guide rollers 11, 12 tighten the filter surface of the filter element 4, maintaining a certain tension to ensure that the filter surface of the filter element 4 withstands sufficient wind pressure.

[0046] In some embodiments of the present application, brushes are provided on the roller surfaces of the first guide roller 11 and the second guide roller 12. These brushes can clean dust accumulated on the filter surface of the filter element 4. At the same time, they increase the friction between the filter element 4 and the first guide roller 11 and the second guide roller 12, tightening the filter surface of the filter element 4 and maintaining a certain tension.

[0047] In some specific embodiments, the second guide roller 12 is located between the first screw 9 and the second screw 10. The second guide roller 12 is in transmission connection with the cleaning motor 13. The second guide roller 12 is provided with an output gear 14. The first screw 9 is provided with a first input gear 15. The second screw 10 is provided with a second input gear 16. The output gear 14 is respectively engaged with the first input gear 15 and the second input gear 16. The power of the cleaning motor 13 is transmitted to the first screw 9 and the second screw 10 via the output gear 14, the first input gear 15, and the second input gear 16, respectively. The power of the cleaning motor 13 is transmitted to the first screw 9 and the second screw 10 via the output gear 14, the first input gear 15, and the second input gear 16, respectively, thereby driving the vibration motor 8 and the negative pressure head 5 to synchronously reciprocate, thereby cleaning the filter surface of the filter element 4.

[0048] In some embodiments of the present application, the vibrating dust removal and self-cleaning coarse air filtration device further includes a first winding motor and a second winding motor. The first winding motor is disposed on the frame 1 and is in transmission connection with the first material roller 2 for driving the first material roller 2 to rotate. The second winding motor is disposed on the frame 1 and is in transmission connection with the second material roller 3 for driving the second material roller 3 to rotate.

[0049] The working principle of the vibration dust removal self-cleaning air coarse filter device provided in the embodiment of the present application is as follows:

[0050] During normal filtration, the filter element 4 is tightened against the filter surface by the first and second guide rollers 11 and 12, maintaining a certain tension to ensure that the filter surface can withstand sufficient wind pressure. As dust accumulates on the filter surface, the wind resistance of the filter element 4 increases. A timed self-cleaning operation can be set based on the dust accumulation of the filter element 4. The second winding motor starts, driving the second guide roller 12 to roll a portion of the filter surface of the filter element 4 downward into the second feed roller 3. At this point, the first winding motor is in a passive drag-enabled state. Simultaneously, the first feed roller 2 rotates, driven by the filter element 4, dragging the reserve filter element 4 on the first feed roller 2 into the filter surface. This completes the renewal of the filter surface of the filter element 4.

[0051] As the filter element 4 rolls toward the second guide roller 12, the vibration motor 8 and the industrial vacuum cleaner main unit 7 are activated: the industrial vacuum cleaner main unit 7 generates high-pressure vacuum suction pressure, which is connected to the negative pressure head 5 via the retractable hose 6. The vibration motor 8 and the industrial vacuum cleaner main unit 7 are aligned and installed on either side of the filter element 4. At the same time, the cleaning motor 13 is activated, and through gear transmission, the first and second screws 9 and 10 rotate simultaneously, driving the vibration motor 8 and the industrial vacuum cleaner main unit 7 to reciprocate synchronously, performing a scanning vibration vacuum self-cleaning operation. The high-frequency vibration head of the vibration motor 8 vibrates and cleans the dust accumulated on the filter surface, and under the action of the vacuum suction negative pressure, the cleaned dust is collected into the industrial vacuum cleaner main unit 7.

[0052] When the filter element 4 on the first material roller 2 is completely consumed and drawn into the second material roller 3, the first winding motor starts, and the second winding motor switches to a driven end state, enabling passive drag. This pulls the second material roller 3 in reverse rotation, drawing the filter element 4 back into the first material roller 2. This cycle continues.

[0053] The vibrating dust removal, self-cleaning, coarse-effect air filtration device of the present application is designed to recycle filter material or filter screen structure. The recycle filter material structure allows the filter material to be replaced every 2-3 years, solving the problems of difficult and high labor costs in filter material replacement and maintenance. The industrial vacuum cleaner main unit 7 enables regular centralized cleaning of dirt, reduces the impact of the equipment on the on-site environment, and reduces labor maintenance costs.
