Description

Dust removal system for asphalt concrete mixing plant

technical field

The utility model relates to the field of dust removal equipment, in particular to a dust removal system for an asphalt concrete mixing station.

Background technique

The asphalt concrete mixing plant is a workstation that makes asphalt after mixing aggregates and mixtures. During the process of mixing and unloading, a large amount of dust is likely to be generated, so bag dust collectors are generally used to remove dust from the air. The working principle of the existing bag filter is to introduce the dust-containing gas into the filter bag and make it pass through the filter bag in the filter bag, and the dust particles will be intercepted and left on the surface of the filter bag to form a dust layer. The clean air passes through the filter bag and then exits the dust collector. However, the cloth bag in the existing dust removal system is easy to block the mesh due to long-term filtering of dust, so it needs to be replaced and cleaned again, which is time-consuming and laborious, and the use of vibration to remove the dust on the cloth bag is less effective.

detailed description

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

Fig. 1 is a schematic structural view of the utility model, and Fig. 2 is a state diagram of the experimental model when beating a cloth bag.

A dust removal system for an asphalt concrete mixing plant, comprising a frame 1, a suction fan 2, an air inlet pipe 3, a filter chamber 4, a cloth bag 5, a vibrating motor 6, an air outlet pipe 7 and an ash hopper 8, and the upper end of the frame 1 is provided with a filter chamber 4, the lower end of the filter chamber 4 is connected with the ash hopper 8, the ash hopper 8 is fixed in the frame 1, the side end of the frame 1 is provided with a vibrating motor 6, the filter chamber 4 is provided with a cloth bag 5, and one end of the filter chamber 4 passes through the inlet The air duct 3 is connected with the suction fan 2, the other end of the filter plate 4 is provided with an air outlet duct 7, the side end of the frame 1 is fixedly connected with a rotating motor 15, the rotating shaft of the rotating motor 15 is fixedly connected with the rotating rod 9, and the rotating rod 9 passes through One side of the filter chamber 4 and the cloth bag 5 is connected with the rotating rod 9, and the indoor top of the filter chamber 4 is welded with a plate body 10, and the outer end surface of the plate body 10 is provided with an arc-shaped protrusion. Both horizontally opposite sides of the filter chamber 4 are provided with ball collars 11 , and both ends of the rotating rod 9 are placed in the ball collars 11 . The upper end of the cloth bag 5 is adhesively connected to the rotating rod 9, and the lower end of the cloth bag 5 is provided with a hook 12, and the hook 12 is hung on the frame 1 crossbeam. The rotating shaft of the frame 1 is fixedly connected with the rotating rod 9 through bolts, and the frame 1 is fixedly connected with the rotating motor 15 through the bracket 13 . The end face of the filter chamber 4 perpendicular to the ground is provided with an opening, and the end face of the filter chamber 4 provided with the opening is hingedly connected with the cover plate 14, and the cover plate 14 is matched with the opening.

First start the suction fan, suck the dust-containing air in the room, send the air into the filter chamber 4 through the air inlet pipe 3, and the flowing air hits the cloth bag 5 woven by fabric. When the particle size of the dust is larger than the cloth bag 5, the dust will be sieved and dropped into the ash hopper 8. Finally, the filtered air will rush out of the filter chamber 4 through the air outlet pipe 7 . When the dust is all accumulated on the ash hopper 8, the vibrating motor 6 is started. Since the vibrating motor 6 and the ash hopper 8 are fixed on the frame 1 by bolts, the vibrating motor 6 can vibrate the dust on the inner wall of the ash hopper 8. All shake and fall into the collection box.

When the dust on the cloth bag 5 accumulates too much, causing the pores between the fibers to be blocked, thereby hindering the air flow, the cover plate 14 is first opened, and the hook 12 in the filter chamber 4 is removed from the crossbeam of the frame 1. Then start the rotating motor 15, and now the rotating shaft of the rotating motor will drive the rotating rod 9 to rotate. The filter chamber 4 is a closed box, the two sides of the filter chamber 4 are provided with openings of the same size, and the ball bearings 11 are welded together in the openings, so the two ends of the rotating rod 9 are placed in the ball bearings 11, not only for the rotating rod 9 provides support without impeding its rotation. When the rotating rod 9 rotates, it will drive the cloth bag 5 to rotate together. When the cloth bag 5 is thrown to the highest point, it will hit the arc-shaped protrusion on the top plate 10, and the dust that is beaten will directly fall into the ash hopper within 8. In this way, the method of continuously throwing the cloth bag 5 to the arc-shaped protrusion for slapping greatly improves the efficiency of cleaning the dust accumulated on the cloth bag 5, and due to the smooth arc-shaped surface of the arc-shaped protrusion, the surface of the cloth bag 5 will not be scratched. At the same time, it also increases the efficiency of slap dust removal. After the whole cleaning work is finished, open the cover plate 14 again, and hang the hook 12 on the crossbeam of the frame 1 again, so that the cloth bag 5 can be re-opened for the next filtration.
