DETAILED DESCRIPTION

[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0018] See also Figure 1-7As shown in the figure, this embodiment provides a construction dust removal device, such as Figure 1 As shown, it includes a dust removal body mechanism 1. Specifically, one side of the dust removal body mechanism 1 is connected to a dust suction mechanism 2, and one side of the dust removal body mechanism 1 is rotatably connected to an adjustment mechanism 3;

[0019] Combination Figure 4 As shown, the inner cavity of the dust removal body mechanism 1 is fixedly installed with a self-cleaning mechanism 4; Figure 4-5 As shown, the dust removal body mechanism 1 includes a dust removal cylinder 101, a balance frame 102 is fixedly installed at the bottom of the dust removal cylinder 101, air outlet slots 104 are arranged in a through shape on both sides of the dust removal cylinder 101, a first filter plate 105 connected to the air outlet slots 104 is fixedly installed on the inner wall of the dust removal cylinder 101, and a dust suction fan 109 is fixedly installed on one side of the dust removal cylinder 101. Figure 6 As shown, the first filter plate 105 connected to the air outlet slot 104 and arranged on the inner wall of the dust collecting cylinder 101 is arranged in an arc shape, and is always attached to the inner wall of the dust collecting cylinder 101, so that the gas and dust impurities entering the inner cavity of the dust collecting cylinder 101 are filtered by the first filter plate 105, and then pass through the first filter plate 105 in sequence and discharge the clean gas through the air outlet slot 104. At the same time, combined with Figure 7 As shown, the self-cleaning mechanism 4 includes a limit slide 41 fixedly installed inside the dust removal cylinder 101, and the top of the limit slide 41 is provided with an electric threaded rod 42 rotatably connected to the dust removal cylinder 101, and the outer wall of the electric threaded rod 42 is threadedly connected to a positioning slide 43 slidably connected to the limit slide 41, and both sides of the positioning slide 43 are fixedly installed with a first connecting bracket 44, combined with Figure 6 As shown, a first dust scraping brush plate 45 is fixedly mounted on one side of the two first coupling brackets 44 , and a plurality of second dust scraping brush plates 46 are fixedly mounted on the outer wall of the first dust scraping brush plate 45 .

[0020] It can be understood that when it is necessary to clean the adhered dust and impurities, by driving the electric threaded rod 42 to rotate, the positioning slider 43 can drive the first connecting bracket 44 and the first dust scraper brush plate 45 to translate, and then the first dust scraper brush plate 45 can scrape off the dust and impurities adhered to the inner wall of the first filter plate 105, thereby assisting in cleaning the first filter plate 105, thereby improving the service life of the first filter plate 105 and avoiding the problem of a large amount of dust and impurities adhering to the inner wall of the first filter plate 105, which affects gas circulation and dust filtration.

[0021] Furthermore, the first filter plate 105 and the first dust scraper brush plate 45 are both arranged in an arc state, the centers of the first filter plate 105 and the first dust scraper brush plate 45 are maintained at the same center point, and a plurality of second filter plates 106 are fixedly installed in a circular and equidistant state on one side of the first filter plate 105, and the plurality of second dust scraper brush plates 46 are all arranged in a circular and equidistant state around the outer circumferential surface of the first dust scraper brush plate 45, and each second dust scraper brush plate 46 is respectively inserted between every two second filter plates 106.

[0022] Among them, a plurality of second filter plates 106 are arranged in combination to increase the contact range between the first filter plate 105 and the dust impurities inside the dust removal cylinder 101, thereby improving the quality of filtering the dust content in the air. The purpose of such arrangement is that when the positioning slider 43 is driven to slide as a whole on the inner wall of the first dust scraper brush plate 45 to scrape off the dust adhered to its inner wall, the second dust scraper brush plate 46 also simultaneously removes the dust in the gap between every two second filter plates 106, so that the first filter plate 105 and the second filter plate 106 are always kept in an unobstructed state, which is more convenient for continuous dust filtering to achieve the best air purification effect, and regularly clean the surface of the first filter plate 105 and the second filter plate 106 to extend their service life.

[0023] Furthermore, combined with Figure 5-6 As shown, two guide rods 47 are fixedly installed inside the dust collector 101. The two guide rods 47 are symmetrically arranged with respect to the vertical center line of the dust collector 101, and the two first dust scraping brush plates 45 are slidably installed on the outer walls of the guide rods 47. The purpose of such arrangement is to maintain the stability of the two first dust scraping brush plates 45 when they move back and forth, so that they can always fit with the inner wall of the first filter plate 105, thereby maintaining the stability of the dust scraping movement work.

[0024] Furthermore, combined with Figure 4-5 As shown, the bottom of the dust collection cylinder 101 is connected to a dust storage cylinder 103, and a dust guide plate 107 is fixedly installed at the connection point between the dust collection cylinder 101 and the dust storage cylinder 103. The top of the dust guide plate 107 is provided with a plurality of limiting rollers 108 rotatably connected to the dust collection cylinder 101. The purpose of such a setting is to allow the dust that enters the inner cavity of the dust collection cylinder 101 and is scraped off by the first dust scraping brush plate 45 to fall onto the limiting rollers 108, and smaller dust impurities fall into the inner cavity of the dust storage cylinder 103 through the dust guide plate 107 for unified collection, while larger floc-like dust impurities are isolated on the multiple dust guide plates 107.

[0025] Furthermore, combined with Figure 7As shown, both sides of the positioning slider 43 are fixedly connected with a second connecting bracket 48, one end of the two second connecting brackets 48 are rotatably connected with a friction cylinder 49, and the two friction cylinders 49 are arranged in parallel and in a close fit with the limiting roller 108. In actual use, by driving the positioning slider 43 to drive the first dust scraping brush plate 45 to move and scrape dust, the second connecting bracket 48 moves with the positioning slider 43, synchronously making the friction cylinder 49 roll on the surface of the limiting roller 108, and then driving the limiting roller 108 to start rolling, so that the flocculent impurities and dust isolated on the surface of the limiting roller 108 are rolled and squeezed by the friction cylinder 49 and the limiting roller 108, so that they are agglomerated and fall into the inner cavity of the dust storage barrel 103 for unified collection, so as to avoid the flocculent impurities occupying too much space in the inner cavity of the dust storage barrel 103, thereby affecting the dust collection amount, resulting in the problem that too many impurities in the inner cavity of the dust removal barrel 101 affect the removal of dust in the air.

[0026] More preferably, referring to Figure 2-3 As shown, the dust suction mechanism 2 includes a first guide air cylinder 21 which is connected and arranged on the side of the dust collection cylinder 101 away from the dust collection fan 109, one end of the first guide air cylinder 21 is connected and provided with two second guide air cylinders 22, and the outer walls of the two second guide air cylinders 22 are linearly and equidistantly connected and provided with a plurality of dust suction sleeves 23. In actual use, by starting the dust collection fan 109, suction is generated in the inner cavity of the dust collection cylinder 101, so that external air enters the interior of the second guide air cylinder 22 through the plurality of dust suction sleeves 23, and then enters the inner cavity of the dust collection cylinder 101 through the first guide air cylinder 21, wherein the two second guide air cylinders 22 are always symmetrically arranged about the vertical center line of the first guide air cylinder 21 under normal conditions. The purpose of such arrangement is that when dust collection is carried out at the construction site, the second guide air cylinder 22 and the corresponding plurality of dust suction sleeves 23 arranged in an inclined state can not only increase the dust collection range, but also adjust the dust collection angle according to actual needs.

[0027] During the specific implementation, by starting the dust suction fan 109, the second guide air cylinder 22 and its corresponding multiple dust suction sleeves 23 absorb the dust in the construction site, and by driving the electric threaded rod 42 to rotate, the positioning slider 43 drives the first connecting bracket 44 and the first dust scraping brush plate 45 and the second dust scraping brush plate 46 to move inside the first filter plate 105 and the second filter plate 106, so as to automatically scrape off the dust absorbed into the inner cavity of the dust removal cylinder 101, so that the clean air is discharged through the air outlet slot 104. At the same time, the moving positioning slider 43 synchronously drives the second connecting bracket 48 and the friction cylinder 49 to move on the surface of the limiting roller 108, and rolls and rubs the flocculent dust that falls on the surface of the limiting roller 108 to make it agglomerate, so that it falls and is uniformly stored in the inner cavity of the dust storage cylinder 103, so as to avoid the problem of excessive accumulation of flocculent dust blocking the gaps between multiple limiting rollers 108, thereby affecting the dust falling and collection.

[0028] Further preferably, the adjustment mechanism 3 includes a reciprocating threaded screw 31 rotatably installed on one side of the dust removal cylinder 101, the reciprocating threaded screw 31 penetrates the dust removal cylinder 101 and is fixedly connected to the electric threaded rod 42, the purpose of such a setting is that when the electric threaded rod 42 is rotated, the reciprocating threaded screw 31 can be synchronously driven to rotate, the outer wall of the reciprocating threaded screw 31 is threadedly connected with an internal threaded sleeve 32, the outer wall of the internal threaded sleeve 32 is hinged to two support frames 33, and one end of the two support frames 33 is hinged with a positioning plate 34 fixedly connected to the second guide air cylinder 22, and the two support frames 33 and the positioning plate 34 are always symmetrically arranged about the vertical center line of the reciprocating threaded screw 31 under normal conditions. The purpose of the device is to provide auxiliary limit support for the two second guide air cylinders 22 in synchronization. In actual use, by rotating the reciprocating threaded screw 31, the internal threaded sleeve 32 can drive the support frame 33 to translate on its outer wall, thereby changing the deflection angle of the support frame 33. In this process, the inclination angle of the second guide air cylinder 22 can be synchronously pushed to change, thereby achieving the purpose of driving the second guide air cylinder to swing back and forth on the first guide air cylinder 21, so that when the device is performing vacuuming operations at the construction site, its vacuuming range position can be continuously changed, thereby greatly improving the vacuuming efficiency, reducing dust and fly ash at the construction site, and avoiding the problem that the traditional method can only vacuum at a fixed position, resulting in low vacuuming efficiency.
