Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of dust suppression devices, in particular to a high-efficiency dust suppression mechanism for quartz sand dust. Background Art
[0002] Quartz sand is quartz particles made by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. When preparing quartz sand, it is usually necessary to first perform a preliminary crushing of the quartz stone, and then finely crush it to form quartz sand. During the quartz sand production process, the quartz stone material needs to be fed into the crusher equipment through a feeding mechanism, and then discharged from the crushing equipment after being crushed. The quartz sand is discharged from the crusher onto a conveyor belt. Since a large amount of dust is produced when the quartz sand material is crushed, it is easy to cause dust to fly during transportation. Staying in a place with a large amount of quartz sand dust for a long time can easily cause the quartz sand dust to be inhaled into the lungs, causing silicic lung disease and endangering the health of workers and environmental quality.
[0003] At present, dust removal is generally carried out at different stages in the production of quartz sand. First, the raw materials are screened to reduce the dust therein, thereby reducing the dust in the production process. At the same time, dust collection is carried out during the crushing process. However, the existing devices generally use simple dust collection equipment to adsorb dust, which is not convenient for handling the dust attached to the surface of the quartz sand, and will still bring a lot of dust during the subsequent export. At the same time, water spraying is often used to reduce dust during export, but the water volume after the existing water spray is not easy to control. The dust that comes into contact with water often adheres to the surface of the quartz sand, affecting the quality of the product. Summary of the Invention

[0014] The present invention provides a high-efficiency dust reduction machine for quartz sand dust. In this device, a dust suction mechanism is provided on the outside of the crushing box, and a wiping strip is provided at the discharge port of the discharging frame. The dust generated by the quartz stone after being crushed by the crushing box is passed through the filter screen by means of the dust suction pump in the dust suction mechanism, and is passed through the dust suction frame and the dust suction pipe, and is collected in the dust collecting mechanism, thereby reducing the dust generated when the quartz sand is discharged.

Several wiping strips 8 are staggered. The upper ends of the wiping strips 8 pass through the upper side wall of the discharge frame 3 and the lower side wall of the water storage tank 7 in sequence, and are connected to the water absorbent pad 9. When the quartz sand is discharged from the discharge frame 3, it needs to pass through the wiping strips 8, and the water in the water storage tank 7 is introduced into the wiping strips 8 by the water absorbent pad 9 to ensure that the wiping strips 8 are always in a wet state. When the quartz sand passes through the wiping strips 8, the contact between the wiping strips 8 and the quartz sand is utilized to remove dust from the surface of the quartz sand again. Two crushing rollers 15 are provided on the inner side of the crushing box 1, and a flapping mechanism is provided below the crushing roller 15. Dust collection mechanisms are provided on the left and right side walls of the crushing box 1, and the flapping mechanism is located inside the dust collection mechanism.
[0025] The dust collection mechanism includes a dust collection pump 12, a dust collection pipe 11, a dust collection frame 10 and a dust collection device 13. The output end of the dust collection pump 12 is connected to the dust collection device 13, the input end of the dust collection pump 12 is connected to the dust collection pipe 11, and the end of the dust collection pipe 11 away from the dust collection pump 12 is connected to the dust collection frame 10. The dust collection pump 12 is fixed on the rear outer wall of the crushing box 1. A plurality of ventilation holes 18 are opened on the left and right side walls of the crushing box 1. The lower outer wall of the dust collection frame 10 is connected to the ventilation holes.

A filter 19 is provided on the side wall of the dust collecting frame 10 near the beating mechanism. The dust collecting pump 12 in the dust collecting mechanism is used to pass the dust generated after the quartz stone is crushed by the crushing box 1 through the filter 19, through the dust collecting frame 10 and the dust collecting pipe 11, and is collected in the dust collecting mechanism, thereby reducing the dust generated when the quartz sand is exported;
[0026] The flapping mechanism includes several rotating rollers 16, the front and rear ends of the rotating rollers 16 are respectively connected to the front and rear inner walls of the crushing box 1, and a flapping motor 6 is provided on the front outer wall of the crushing box 1.

Several rotating rollers 16 are staggered, and several rotating rollers 16 are driven by belts. Several flapping plates 17 are provided on the outer side wall of the rotating roller 16. The front outer wall of the crushing box 1 is fixedly connected to the crushing motor 5.

The two crushing rollers 15 is driven by gears, and baffles 14 are provided on the inner walls of the left and right sides of the crushing box 1. The two baffles 14 extend respectively to the top of the two crushing rollers 15 and are inclined inwardly. The two baffles 14 are used to facilitate the gathering of the introduced materials between the two crushing rollers 15. The crushed quartz sand falls onto the beating mechanism, and the rotating roller 16 is driven to rotate under the action of the beating motor 6, which in turn drives the beating plate 17 to rotate. While the crushing equipment is working, the processed quartz sand is beaten by the beating mechanism, thereby slowing down the falling speed of the quartz sand and improving the efficiency of dust collection. At the same time, beating the quartz sand is more conducive to knocking off the dust on the surface of the quartz sand.
[0027] Working principle: When in use, quartz stone is introduced from the feed hopper 2, and is guided by the two baffles 14 to the two crushing rollers 15. The crushing motor 5 drives the two crushing rollers 15 to rotate to crush the quartz stone. The crushed quartz sand falls onto the beating mechanism, which drives the rotating roller 16 to rotate under the action of the beating motor 6, and then drives the beating plate 17 to rotate. While the crushing equipment is working, the beating mechanism is used to beat the processed quartz sand, thereby slowing down the falling speed of the quartz sand and improving the efficiency of dust collection. At the same time, beating the quartz sand is more conducive to knocking off the dust on the surface of the quartz sand. The dust suction pump 12 in the dust suction mechanism is used to crush the quartz stone after it has been crushed. The dust generated after the box 1 is crushed passes through the filter 19, the dust suction frame 10 and the dust suction pipe 11, and is collected in the dust collecting mechanism, thereby reducing the dust generated when the quartz sand is discharged. When the quartz sand is discharged from the discharge frame 3, it needs to pass through the wiping strip 8. The upper end of the wiping strip 8 is connected to the absorbent pad 9 in the water storage tank 7 to ensure that the wiping strip 8 is always in a wet state. When the quartz sand passes through the wiping strip 8, the wiping strip 8 is used to remove dust on its surface again. At the same time, multiple groups of wiping strips 8 are used to wipe and clean the rolling quartz sand at different positions, thereby reducing the dust problem caused by the quartz sand being discharged, and effectively solving the problem of a large amount of dust flying when the quartz sand falls from the crusher to the conveyor belt.
