[0025] To enable those skilled in the art to better understand the present invention, 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] The first embodiment of this utility model: like Figures 1-4 As shown, a fully sealed dust removal mechanism according to this embodiment includes a frame 1 and a dust removal unit mounted on the frame 1. The dust removal unit includes a fan, an air inlet 3 located on one side of the top of the fan, an air outlet assembly 4 located at the bottom of one side of the fan, and a filter cloth 12 located between the air inlet 3 and the air outlet assembly 4.

[0027] A sealed housing 2 is installed on the frame 1 outside the dust collector unit, which completely encloses the entire dust collection mechanism. The air inlet 3 and the air outlet assembly 4 are installed simultaneously on the sealed housing 2, forming a single air inlet and outlet channel.

[0028] Several transparent viewing windows 5 are installed on the sealed housing 2 for observing the internal working status.

[0029] Support frames 6 are installed inside the sealed housing 2 on both the left and right sides of the blower. Filter cloth unwinding rollers 7 and filter cloth winding rollers 8 are respectively installed on the top of the support frames 6 on both sides for unwinding and winding the filter cloth 12. A clean passage 11 is provided inside the blower between the air inlet 3 and the air outlet 4 for the filter cloth 12 to pass through. After being unwound from the filter cloth unwinding rollers 7, the filter cloth 12 passes through the clean passage 11 and is finally wound onto the filter cloth winding rollers 8.

[0030] A first cleanroom assembly 9 and a second cleanroom assembly 10 with identical structures are sequentially installed inside the sealed housings 2 on both sides of the clean passage 11. The first cleanroom assembly 9 includes a cleanroom 18 installed inside the sealed housing 2. Through holes 19 are provided on both the left and right sides of the center of the cleanroom 18 for the filter cloth 12 to pass through. Cleanroom rollers 22 are installed at the top and bottom of the cleanroom 18 via movable rods 21. Both cleanroom rollers 22 are located on the side closest to the through holes 19. The movable rods 21 are vertically mounted inside a fixed sleeve 20 inside the cleanroom 18. A spring 23 is installed on the movable rods 21 inside the fixed sleeve 20, so that the cleanroom rollers 22 can adaptively press against the surface of the filter cloth 12.

[0031] A first dustproof net 14 is also installed in the clean channel 11 below the filter cloth 12. The first dustproof net 14 is circulated by several drive rollers 13 mounted on the support frame 6. At least one tension roller 15 is also installed on the support frame 6 to tension the first dustproof net 14. The tension roller 15 can move freely under the drive of the tensioning cylinder, thereby adjusting the tension of the first dustproof net 14 in real time.

[0032] The air outlet assembly 4 includes an air outlet housing 24 mounted on the fan and the sealing housing 2, with an exhaust port 25 on the inner side of the air outlet housing 24. A filter element 27 is installed inside the air outlet housing 24. A first retaining ring 26 is fixedly installed inside the air outlet housing 24 on the inner side of the filter element 27, and a second retaining ring 28 is movably installed inside the air outlet housing 24 on the outer side of the filter element 27. A slider 29 on the outer side of the second retaining ring 28 is inserted into a groove 30 inside the air outlet housing 24. A top block 33 located inside the cover plate 31 is pressed against the inner slider 29 to achieve quick locking. A cover plate 31 is installed on the air outlet housing 24 outside the second retaining ring 28, with an air outlet 32 ​​on the cover plate 31. A second dust filter 34 is installed on the cover plate 31 outside the air outlet 32 ​​to provide secondary filtration protection.

[0033] A cleanroom system 16 and a sensor system 17 are also installed inside the sealed housing 2 to maintain an internal clean environment and monitor operating parameters.

[0034] The second embodiment of this utility model: like Figures 1-4 As shown, this embodiment presents a fully sealed dust removal mechanism, which includes a frame 1 and a sealed housing 2, forming a completely enclosed working environment. Dust-laden air enters the device through the top air inlet 3, is filtered by the filter cloth 12, and then clean air is discharged through the bottom air outlet assembly 4.

[0035] The core work unit includes: Filter cloth conveying system: The filter cloth 12 is released from the filter cloth unwinding roller 7 on the left, passes through the first clean assembly 9, the clean channel 11, and the second clean assembly 10 in sequence, and is finally wound up by the filter cloth winding roller 8 on the right, forming a continuous filtration cycle.

[0036] Multi-stage cleaning system: The first cleaning component 9 and the second cleaning component 10 have the same structure, both including a clean chamber 18, a through hole 19, a movable rod 21, a cleaning roller 22, a fixed sleeve 20, and a spring 23. The spring 23 ensures that the cleaning roller 22 always maintains appropriate contact pressure with the filter cloth 12, ensuring cleaning effect.

[0037] Dustproof net system: The first dustproof net 14 runs in a cycle under the action of the transmission roller 13 and the tension roller 15. The tension roller 15 is driven by the tension cylinder and the tension of the first dustproof net 14 can be adjusted as needed.

[0038] Air outlet filtration system: The air outlet assembly 4 includes an air outlet housing 24, an exhaust port 25, a filter element 27, a first retaining ring 26, a second retaining ring 28, a slider 29, a slide groove 30, a cover plate 31, an air outlet 32, a top block 33, and a second dustproof mesh 34. The filter element 27 is fixed by the retaining ring structure for easy replacement, and the second dustproof mesh 34 provides additional filtration protection.

[0039] Monitoring system: The viewing window 5 facilitates observation of the internal working status, the sensor system 17 monitors the system operating parameters, and the cleanroom system 16 ensures a clean internal environment.

[0040] The working process of this embodiment: When the equipment is started, dusty air enters the sealed housing 2 through the air inlet 3. The filter cloth 12 performs primary filtration at the clean channel 11, intercepting most of the dust. When the filter cloth 12 passes through the first cleaning component 9, the cleaning roller 22 removes dust and other substances that may be attached to the surface. The filter cloth 12, which continues to operate, undergoes a second cleaning process via the second cleaning component 10. Clean air is discharged after passing through the dual filtration of the air outlet assembly 4; The first dustproof net 14 maintains appropriate tension under the action of the tensioning roller 15, and works together to filter; The internal working status can be observed at any time through the viewing window 5; When the filter element 27 needs to be replaced, open the cover plate 31, remove the old filter element through the slider 29 and the slide groove 30, and replace it with a new filter element.

[0041] This invention effectively solves the problems of dust leakage and incomplete cleaning in traditional dust collectors through a fully sealed structure and a multi-stage cleaning system, and has the advantages of high filtration efficiency, convenient maintenance and stable operation.
