Description

Technical Field

[0001] The invention relates to the technical field of mine dust suppression equipment, and in particular to a mine spray dust suppression device. Background Art

[0002] In the process of underground coal mining, various particles such as coal dust and rock dust are generated during the drilling, cutting, loading, coal dropping, blasting and transportation of the mine. Dust is a solid particle that can float in the air. Due to the special properties of dust and the size of the particle size, it is very harmful to the human body. Workers working in coal mines are prone to pneumoconiosis if they inhale it for a long time. Dust also has a great impact on industrial production. It reduces product quality and machine working accuracy, affects the visibility of the working environment, and some dust can explode under certain conditions. Moreover, dust with excessive concentration discharged into the atmosphere also causes environmental pollution. Therefore, dust removal is very necessary. In order to control dust, reduce its harm, improve the working environment of the workplace, and reduce the occurrence of occupational diseases among underground workers, a spray water dust removal system is generally set up underground for dust reduction. It is widely used in underground main lanes, belt transport lanes, belt conveyor transfer points, return air lanes, coal mining machine brackets, etc., which effectively reduces the dust concentration in various working environments and creates a comfortable and safe working environment for employees.

[0003] When the existing spray dust suppression device is in use, the nozzle is exposed for a long time during the non-working period, and after the dust suppression, the nozzle is relatively wet. The long-term exposure can easily lead to the adhesion of dust, which eventually causes condensation into lumps, thus affecting the subsequent spray dust suppression. Moreover, after the spray dust suppression, because the dust suppression adopts the atomization of water, after the dust suppression, the dust with water stains falls on the ground, causing the humidity in the mine environment to increase, thereby causing a certain impact on the staff. Moreover, when there is a lot of dust, after the dust suppression, the stickiness of the ground increases, which affects the walking of people. Summary of the invention

[0004] The main purpose of the present invention is to provide a mining spray dust suppression device, which mainly solves the following technical problems:

[0005] When the existing spray dust suppression device is in use, the nozzle is exposed for a long time during the non-working period, and after the dust suppression, the nozzle is relatively wet. The long-term exposure can easily lead to the adhesion of dust, which eventually causes condensation into lumps, thus affecting the subsequent spray dust suppression. Moreover, after the spray dust suppression, because the dust suppression adopts the atomization of water, after the dust suppression, the dust with water stains falls on the ground, causing the humidity in the mine environment to increase, thereby causing a certain impact on the staff.

[0010] Furthermore, mounting blocks are provided on both sides of the lower surface of the interior of the fixing part, and scrapers are provided on both sides of the mounting blocks. Two driven wheels are provided inside the fixing part, and the motor is rotatably connected to the driven wheels through a belt. When extending downward, the motor is turned on while pulling the moving part, and the unfolding of the belt is used as the extension of the object, and the scraper is in contact with the belt. After the dust reduction is completed, the motor is controlled to rotate in the opposite direction to wind the belt. While winding, the scraper is used to scrape it, so that it is discharged into the storage box through the discharge port.

During the winding process, the moving part moves toward the fixed part. During the movement, the scraper scrapes off the dust adhering to the belt, and the scraped dust enters the storage box through the discharge port.

The nozzles are air-water mixed atomizing nozzles, which are convenient for atomizing water. A drain pipe is arranged inside the top plate. The drain pipe gradually becomes vertical with the top plate as the movable plate moves downward, and the drain pipe is located directly below the nozzle. After the nozzle atomizes the water, the top plate is pressurized under the action of the supercharger, so that the atomized gas is discharged from the water outlet under the action of pressure, and the coal dust is treated by dust reduction, thereby avoiding blockage of the nozzle after use and protecting the nozzle.

[0020] Compared with the prior art, the spray dust reduction device of the present invention, when in use, starts the motor and stretches the moving part to both sides of the fixed part so that the side of the moving part contacts the wall. After dust reduction, the dust falls on the belt below. After the dust reduction is completed, the motor is started to rotate in the opposite direction to recycle the belt. During the recycling process, the belt is scraped with a scraper, which is convenient for recycling and reuse of the dust-reduced material, avoiding the increase of environmental humidity and ensuring the comfort of workers.

[0036] The present invention provides a tempered glass fixing device, and the specific steps are as follows:

[0037] Step 1: Move the device to a place where spray dust reduction is required under the action of the universal wheel (2), and control the servo motor (9) and the hydraulic telescopic rod (16) to start at the same time, so that the movable plate (25) moves downward until the storage box (36) touches the ground.

During the stretching process, the drain pipe (17) squeezes the slider (24), thereby compressing the spring (21) on one side of the slider (24), so that the drain pipe (17) can move downward.

[0038] Step 2: Turn on the motor (29) and pull the moving part (42) toward both sides at the same time. The start of the motor (29) causes the belt (30) to extend, and under the action of the fixed block (34), the belt (30) fills the gap between the fixed part (41) and the moving part (42), so that the atomized dust particles adhere to the belt (30);

[0039] Step 3: Start the water pump (5) and the air pump (6) at the same time, introduce gas and water into the water pipe (12), and mix them in the nozzle (14). The nozzle (14) is an air-water mixing atomizing nozzle, so that the water in the water pipe (12) can be atomized and sprayed out, and the booster (10) is turned on.

The servo motor (9) and the hydraulic telescopic rod (16) are controlled to start simultaneously, so that the movable plate (25) moves downward until the storage box (36) touches the ground. During the downward movement of the movable plate (25), the drain pipe (17) is stretched downward. During the stretching process, the drain pipe (17) squeezes the slider (24), thereby compressing the spring (21) on one side of the slider (24) to facilitate the downward movement of the drain pipe (17). The drain pipe (17) is located directly below the nozzle (14). The motor (29) is turned on and the moving part (42) is pulled to both sides at the same time. The start of the motor (29) causes the belt (30) to extend until the side of the moving part (42) contacts the wall. Under the action of the fixed block (34), the belt (30) fills the gap between the fixed part (41) and the moving part (42). The gap between the nozzle (14) and the top plate (11) is formed so that the atomized dust particles adhere to the belt (30), and the top plate (11) effectively prevents the nozzle (14) from being clogged by the coal dust after the dust is removed, thereby protecting the nozzle (14). At the same time, the water pump (5) and the air pump (6) are started to introduce gas and water into the water pipe (12) and mix them in the nozzle (14). The nozzle (14) is a gas-water mixing atomizing nozzle, so that the water in the water pipe (12) can be atomized and sprayed out, and the supercharger (10) is started. The booster (10) increases the pressure in the device to facilitate the discharge of mist through the water outlet (19). After the dust reduction is completed, the motor (29) is rotated in the opposite direction to facilitate the winding of the belt (30). During the winding process, the moving part (42) moves toward the fixed part (41). During the movement, the scraper (33) scrapes off the dust adhering to the belt (30). The scraped dust enters the storage box (36) through the discharge port (35), thereby ensuring the humidity balance in the mine.
