Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and particularly relates to an air purification and dust removal device for workshop production. Background Art

[0002] In a workshop, the production of concrete structural members will generate a large amount of dust and impurities. Workers staying in this environment for a long time will affect their physical health. Therefore, dust removal fans are placed in the workshop. The existing dust removal fans in factories suck dust in the air through the fan blades, and after being filtered by the filter cloth, they are released into the air. Since there is a lot of dust in the concrete structural member production workshop, the filter mesh is easily blocked by dust and particles, affecting the air suction speed of the fan blades and resulting in the reduction of the purification speed. In view of the above problems, we propose an air purification and dust removal device for workshop production. Summary of the Invention

[0003] In view of the above problems, the present invention provides an air purification and dust removal device for workshop production. When the filter mesh is blocked by dust and particles, resulting in a decrease in wind force, the force pushing the wind blocking cloth by the wind force decreases. Under the squeezing force of the spring, the sliding cylinder moves, and the keyway approaches the key. The key is inserted into the keyway. When the rotating shaft rotates, it drives the sliding cylinder to rotate, drives the retractable filter mechanism to operate through the belt pulley mechanism, and replaces the filter mesh that blocks dust. When the wind speed passing through the filter mesh becomes larger, it blows the wind blocking cloth to move, drives the rectangular frame to move, drives the sliding cylinder to move, the key is separated from the keyway, the sliding cylinder does not rotate following the rotating shaft, and the filter mesh does not continue to be unfolded and laid.

[0004] An air purification and dust removal device for workshop production provided by the present invention includes a guide rail frame, a moving frame is movably arranged on the guide rail frame, suction chambers are respectively connected to both ends of the moving frame, and a sealing cover plate is hermetically connected to the upper part of the suction chambers.

[0005] A retractable filter mechanism is arranged in the suction chamber. The retractable filter mechanism includes a winding shaft and a filter mesh. There are two groups of winding shafts, which are symmetrically distributed with the center line of the suction chamber as the reference and are rotationally connected to the suction chamber. One end of the filter mesh is wound around one of the winding shafts, and the other end is fixedly connected to the other winding shaft. A perforated plate is fixedly connected in the suction chamber, and the filter mesh bypasses both sides of the perforated plate. A fan blade and a rotating shaft are further arranged in the suction chamber. The fan blade and the rotating shaft are rotationally connected to the suction chamber, and the central shaft of the fan blade is in transmission connection with the rotating shaft.

[0006] A wind adaption part is also provided in the dust collection bin, which is axially telescopic and slides on the rotating shaft. The wind adaption part includes an elastic telescopic part and a rectangular frame. One end of the elastic telescopic part is rotatably connected to the dust collection bin and is axially slidable on the rotating shaft. The rectangular frame is connected to the other end of the elastic telescopic part, and a wind-blocking cloth is provided in the rectangular frame.

[0007] A pulley mechanism is also provided in the dust collection bin, which slides axially on the surface of the wind adaptor. A rotating rod is rotatably connected in the dust collection bin, which is transmission-connected to the pulley mechanism and to the winding shaft. A rotating ring 1 slides axially on the winding shaft, and a rotating ring 2 is coaxially fixed on the rotating rod. The rotating ring 1 is rotationally connected to the dust collection bin, and the rotating ring 1 and the rotating ring 2 are connected by an annular belt.

[0008] The pulley mechanism includes a sleeve wheel support ring, a sleeve wheel, and a worm. The sleeve wheel support ring is fixedly connected to the dust collection bin. The sleeve wheel support ring is coaxially movably sleeved on the elastic telescopic part. There are two groups of sleeve wheels, which are connected to each other by an annular connecting belt. One of the sleeve wheels is rotatably connected to the sleeve wheel support ring and axially slidably sleeved on the surface of the elastic telescopic part. The worm is connected to the dust collection bin through a bracket, and the other sleeve wheel is coaxially fixedly sleeved on the worm.

[0009] Beneficial effects of the present invention: The present invention provides an air purification and dust removal device for workshop production: 1. When the filter cloth is blocked by dust and particles, resulting in a decrease in wind force, the force of the wind pushing the wind-blocking cloth decreases. Under the extrusion force of the spring, the sliding cylinder moves, and the key slot approaches the key bar. The key bar is inserted into the key slot. When the shaft rotates, the sliding cylinder is driven to rotate, and the reel-type filter mechanism is driven to operate through the pulley mechanism to replace the dust-blocking filter cloth. When the wind speed passing through the filter cloth increases, the wind-blocking cloth is blown to move, driving the rectangular frame to move, driving the sliding cylinder to move, the key bar is separated from the key slot, the sliding cylinder will not rotate with the shaft, and the filter cloth will not continue to be unfolded and laid. 2. The reel is slidably inserted into the rotating ring 1, and the rotating ring 1 is rotatably connected to the dust collection bin, so that the reel is easily pulled out from the rotating ring 1 to replace the filter cloth as a whole.

[0021] Principle of the present invention: The moving frame 2 is movably arranged on the guide rail frame 1 and can drive the dust suction bin 3 to move to suck dust at multiple positions. When impurities and particles adhere to the filter mesh 10, the ventilation effect of the filter mesh 10 becomes poor, the wind passing through the filter mesh 10 and blowing onto the wind blocking cloth 15 weakens, and the force pushing the wind blocking cloth 15 by the wind decreases. Under the squeezing force of the spring 30, the sliding cylinder 29 moves, and the key slot 34 approaches the key 31. When the key 31 is inserted into the key slot 34 and the rotating shaft 6 rotates, the sliding cylinder 29 is driven to rotate, and then the collar wheel 17 is driven to rotate. The other collar wheel 17 is driven to rotate through the annular connecting belt, the worm 18 is driven to rotate, the worm gear 33 is driven to rotate, the rotating rod 12 is driven to rotate, and then the second rotating ring 21 is driven to rotate, and then the annular belt 22 is driven to rotate annularly, and then the first rotating ring 20 is driven to rotate, driving the two winding shafts 9 to rotate. One of the winding shafts 9 winds the filter mesh 10, and the other winding shaft 9 releases the filter mesh 10, so that the blocked filter mesh 10 is wound onto the winding shaft 9, and the released filter mesh 10 is laid on the surface of the mesh plate 11. At this time, the wind speed passing through the filter mesh 10 increases, blowing the wind blocking cloth 15 to move, driving the rectangular frame 14 to move, driving the sliding cylinder 29 to move, the key 31 is separated from the key slot 34, and the sliding cylinder 29 does not rotate following the rotating shaft 6, and the filter mesh 10 will not continue to be unfolded and laid.
