Description

A dust suppression device for environmental protection in mining environment construction

Technical Field

The invention relates to the technical field of dust suppression devices, and in particular to a dust suppression device for environmental protection in mining environment construction.

Background Art

In order to effectively reduce dust concentration and improve the working environment in mines, fog cannons are usually used. Fog cannons are based on the principle of air delivery. They first use a high-pressure pump and a fine atomizing nozzle to atomize water, and then use the fan air volume and wind pressure to send the atomized water mist to a longer distance. When the water mist reaches a longer distance, it adheres to the dust in the air and makes the dust fall.

Chinese patent CN216446957U discloses a tunnel auxiliary dust reduction spray device for mining engineering. When the device performs dust reduction operations, the rotating brush roller inside the cleaning cylinder will be driven by the airflow to rotate, and the dust filtered on the filter screen will be brushed off to prevent clogging. However, when the rotating roller brush is brushing the dust, some of the dust brushed off will adhere to the rotating roller brush. As the working time of the device increases, more and more dust accumulates on the rotating roller brush, which makes the cleaning effect of the rotating roller brush worse. When the rotating roller brush rotates, some dust will be thrown into the motor in its blower. When a large amount of dust accumulates on the motor, the heat dissipation effect of the motor will be deteriorated, thereby affecting the normal operation of the motor, reducing the air volume and air pressure of the fan, and resulting in poor dust reduction effect of the fog cannon.

The dust prevention component 5 includes a filter plate 51, and the filter plate 51 is installed in the rear end of the wind tube 2. The cleaning component 6 is arranged on the filter plate 51. After the plate 51 filters the dust entering the air duct 2, the cleaning component 6 cleans the dust on the filter plate 51. The cleaning component 6 includes a driving shaft 61, a scraper 62 and a rolling brush 7. The driving shaft 61 passes through the filter plate 51, and a plurality of scrapers 62 are evenly distributed thereon in a circular shape. One end of the driving shaft 61 is connected to a cleaning motor 63. When cleaning the dust on the filter plate 51, the cleaning motor 63 drives the scraper 62 to rotate on the filter plate 51 through the driving shaft 61.

The steering component 4 drives the wind tube 2 to rotate in the horizontal direction through the bearing turntable 41, so that it faces the direction where water mist needs to be sprayed. At the same time, the steering component 4 lifts the wind tube 2 upward, so that the wind tube 2 is tilted up at a certain angle, and the distance of the water mist sprayed by the wind tube 2 is maximized. In this process, the water supply component 3 supplies water to the rolling brush 7 of the wind tube 2 and the cleaning component 6 respectively, and the wind tube 2 turns the water into water mist and sprays it out to perform dust reduction operations on the mine. When the wind tube 2 is working, air mixed with dust will be sucked in from its rear end.

Embodiment 2

The difference from the above embodiment is that a mounting seat 26 is fixedly connected to the outer side of the front end of the air duct 2 , a dust cover 28 is rotatably connected to the mounting seat 26 , and a buckle 27 is welded on one side of the air duct 2 .

When the device is not in use, the dust cover 28 closes the front end of the wind tube 2 to prevent dust from entering. When in use, the dust cover 28 is opened by the handle 281, and the handle 281 is snapped into the buckle 27 on one side of the wind tube 2 to prevent the dust cover 28 from swinging at the front end of the wind tube 2 during operation and affecting the operation of the wind tube 2. When the dust reduction work is completed, the handle 281 is pulled out from the buckle 27 to allow the dust cover 28 to close the front end of the wind tube 2.

The difference from the above embodiment is that a handle 281 is fixedly mounted on one side of the dust cover 28 , and the handle 281 corresponds to the buckle 27 .

Working principle: When the device is not in use, the dust cover 28 closes the front end of the wind tube 2 to prevent dust from entering. When in use, the device is placed at a location in the mine where dust reduction is required by pushing the installation cabinet 1. After determining the location, the dust cover 28 is opened by the handle 281, and the handle 281 is snapped into the buckle 27 on the side of the wind tube 2 to prevent the dust cover 28 from swinging at the front end of the wind tube 2 during operation and affecting the operation of the wind tube 2. The device is then started, and the steering assembly 4 drives the turntable gear ring 45 to rotate through the servo motor 46 through the driving gear 47, so that the bearing turntable 4 1 drives the wind tube 2 to rotate in the horizontal direction, toward the direction where water mist needs to be sprayed, and at the same time, the hydraulic lifting rod 43 extends its output shaft to lift the wind tube 2, so that the wind tube 2 stops working after rotating to a suitable elevation angle on the support frame 411, and the distance of the water mist sprayed by the wind tube 2 is maximized. In this process, the high-pressure pump 32 transports the water stored in the water storage tank 31 to the three-way joint 441, and the three-way joint 441 divides the water transported by the high-pressure pump 32 into two parts, most of which is transported to the atomizing nozzle, and a small part of the water is transported to the water delivery tank 711 of the fixed sleeve 71;

After the water delivery component 3 delivers water into the atomizing nozzle 21, the atomizing nozzle 21 atomizes the water, and the delivery motor 22 drives the fan blades 23 to rotate, and the water mist atomized by the atomizing nozzle 21 is sprayed out of the wind tube 2 to perform dust reduction operations on the mine. When the wind tube 2 is working, air mixed with dust will be sucked in from its rear end. At this time, the filter plate 51 of the dustproof component 5 filters the dust out of the air, so that the clean air enters the wind tube 2, and the dust will remain on the filter surface of the filter plate 51. At this time, the cleaning motor 63 drives the driving shaft 61 to rotate, so that the driving shaft 61 drives the scraper 62 to rotate on the filter surface of the filter plate 51, and most of the dust accumulated on the filter plate 51 is scraped off. In this process, when the driving shaft 61 is not rotating, there is a certain distance between the rolling brush 7 and the filter plate 51. When the driving shaft 61 rotates, the driving shaft 61 cooperates with the slider 712 through the thread groove 611, so that the slider 712 drives the fixed sleeve 71 to slide in the thread groove 611 toward the filter plate 5 1 direction, and the fixed sleeve 71 aligns the several sponge rollers 73 thereon between every two tube sheets, and compresses the supporting spring 613. During the movement of the fixed sleeve 71, the water in the water delivery trough 711 is sent by the water delivery component 3, and the water is immersed in the sponge roller 73 through the through hole 721 on the rotating shaft 72, so as to wet the sponge roller 73 and improve the cleaning effect of the sponge roller 73. When the sponge roller 73 hits the filter surface of the filter plate 51, the fixed sleeve 71 stops moving on the driving shaft 61 and starts to rotate synchronously with the driving shaft 61. During this process, the sponge roller 73 rolls on the filter plate 51 through the rotating shaft 72 to clean the filter plate 51, so that the filter surface of the filter plate 51 remains unobstructed and is not blocked by dust. When the rolling brush 7 cleans the filter plate 51, the rolling brush 7 hits the filter plate 51 to squeeze out the sewage, so that the sewage flows into the collecting cover 52. The sewage flowing into the collecting cover 52 will be mixed with the dust scraped off by the scraper 62 and discharged from the drain port 521;

After the device completes the dust reduction work, the water delivery component 3, the air cylinder 2 and the cleaning component 6 all stop working. After the driving shaft 61 stops rotating, the compressed support spring 613 recovers its deformation and pushes the fixed sleeve 71 outward, so that the fixed sleeve 71 moves back to its original position along the threaded groove 611 and separates from the filter plate 51. At this time, the handle 281 is pulled out of the buckle 27, so that the dust cover 28 closes the front end of the air cylinder 2 and waits for the next use.
