DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 A high-efficiency dust removal and filtering device for asphalt hot regeneration mixture mixing equipment includes a box body 1, an air inlet is opened on the surface of the box body 1, an air inlet pipe 2 is fixedly installed in the air inlet, an air outlet is opened on the lower surface of the box body 1, an air outlet pipe 3 is fixedly installed in the air outlet, by installing the box body 1 in the middle of the connection between the pipe fittings on the flue, the asphalt smoke generated by the original drum will first enter the box body 1 through the air inlet pipe 2.

[0023] A short baffle 4 is fixedly installed at an angle in the box body 1, and the short baffle 4 is located at the inlet and outlet. Two middle baffles 5 are fixedly installed in the box body 1, and the two middle baffles 5 are respectively fixedly installed at the upper end and the lower end of the box body 1. A support frame 6 is fixedly installed vertically and symmetrically in the box body 1, and a plurality of bending plates 7 are fixedly installed on the two support frames 6. The plurality of bending plates 7 are all fixedly installed at an angle on the two support frames 6, and the plurality of bending plates 7 are layered in a door curtain shape. A long baffle 8 is fixedly installed on the uppermost bending plate 7, and the long baffle 8 is fixedly installed on the inner wall of the box body 1. A dust discharge port is opened on the lower surface of the box body 1.

[0024] After entering the box 1, the asphalt smoke will first hit the inclined short baffle 4, thereby reducing the air volume of the asphalt smoke in the pipeline and allowing the large particles of smoke generated by the asphalt smoke to fall to the bottom of the box 1. The asphalt smoke then passes through the middle baffle 5 welded in the S-shaped position to further reduce the air volume of the asphalt smoke, and finally passes through the bent plate 7 welded in layers like a door curtain to slow down the air volume again, allowing the large particles of asphalt smoke to fall to the bottom of the box 1, achieving a secondary filtering and dust removal effect in the filter box, so that the large particles of asphalt smoke generated from the original drum are removed, reducing pollution to the environment, playing an environmental protection role, and improving the practicality of the device.

[0025] A bottom frame 9 is fixedly mounted on the box body 1, a plurality of legs 10 are fixedly mounted on the lower surface of the bottom frame 9, an external frame 17 is fixedly mounted on the surface of the box body 1, the external frame 17 serves to reinforce the strength of the box body 1, and the bottom frame 9 and the plurality of legs 10 can be easily installed on site and are easy to operate.

[0026] Inspection ports 11 are symmetrically arranged on the surface of the box body 1 , and observation ports 12 are arranged on the surface of the box body 1 . One observation port 12 and two inspection ports 11 are convenient for later maintenance and inspection of the flue filter box equipment.

[0027] A strip hole is provided on the surface of the middle baffle 5 installed at the lower end of the box body 1, and a scraper 13 is slidably provided on the inner bottom wall of the box body 1. Pull rods 14 are symmetrically fixedly installed on the scraper 13. One end of the two pull rods 14 passes through the box body 1 and is fixedly installed with a strip rod 15. The two pull rods 14 are both sleeved with a telescopic spring 16, and the two ends of the telescopic spring 16 are fixedly connected to the inner wall of the box body 1 and the surface of the scraper 13 respectively.

[0028] When there is a large amount of large smoke particles accumulated at the bottom of the box body 1, the strip rod 15 can be pulled, and then the scraper 13 can be driven to slide on the bottom of the box body 1 through the pull rod 14. When the scraper 13 moves toward the ash discharge port, the telescopic spring 16 is compressed, which will drive the accumulated large smoke particles to move toward the ash discharge port and concentrate them near the ash discharge port, which is convenient for the later processing of the large smoke particles. When the strip rod 15 is loosened, the scraper 13 will be driven to move away from the ash discharge port under the action of the elastic force of the telescopic spring 16 until it contacts the two support frames 6.

[0029] In the utility model, after the asphalt smoke enters the box body 1, it will first hit the inclined short baffle 4, thereby reducing the air volume of the asphalt smoke in the pipeline and allowing the large particles of smoke generated by the asphalt smoke to fall on the bottom of the box body 1, and then the asphalt smoke passes through the middle baffle 5 welded in the S-shaped position to further reduce the air volume of the asphalt smoke, and finally passes through the bent plate 7 welded in layers like a door curtain to slow down the air volume again, so that the large particles of asphalt smoke can fall to the bottom of the box body 1, achieving the secondary filtering and dust removal effect in the filter box, so that the large particles of asphalt smoke generated from the original drum are removed, reducing pollution to the environment, playing an environmental protection role, and improving the practicality of the device.

[0030] In general, in view of the technical problems: the direction of the pipeline will be very complicated, it is inconvenient to install, it is easy to damage the quality of the pipe fittings, and it cannot achieve the effect of smoke and dust removal, which will cause a lot of waste and pollution, and the practicality is poor; the technical solution is adopted: the middle baffle 5 welded in the S-shaped position in the filter box and the bent plate 7 welded in layers like a door curtain play a double filtering and dust removal role; because the implementation process of the technical solution is: after the asphalt smoke enters the box body 1, it will first hit the short baffle 4 installed obliquely, thereby reducing the wind volume of the asphalt smoke in the pipeline, and allowing the asphalt smoke to The large particles of smoke produced by the blue smoke fall on the bottom of the box 1, and then the asphalt smoke passes through the middle baffle 5 welded in the S-shaped position to further reduce the air volume of the asphalt smoke, and finally passes through the bent plate 7 welded in layers like a door curtain to slow down the air volume again, so that the large particles of asphalt smoke can fall on the bottom of the box 1, achieving the secondary filtering and dust removal effect in the filter box; therefore, the technical problem can definitely be solved, and the technical effect achieved is: the large particles of asphalt smoke generated from the original drum are removed, the pollution to the environment is reduced, the environmental protection effect is played, and the practicability of the device is improved.
