Description

Technical Field

[0001] The invention belongs to the technical field of mining engineering, and specifically relates to a dust removal device for mining engineering, which has adjustable dust suction wind force, high dust suction efficiency, good dust removal effect, and convenient cleaning of accumulated dust. Background Art

[0002] During the mining process, a large amount of dust will be generated due to production links such as drilling and blasting, crushing, screening, loading and unloading, and transportation. This dust will float in the air environment, causing potential harm to the surrounding environment and human body. Therefore, it cannot be discharged directly into the atmosphere and must undergo dust removal treatment.

[0003] At present, there are mainly water spray dust removal, vacuum dust removal, filtration dust removal, high-voltage electrostatic dust removal and other solutions for mining dust. Although water spray dust removal is cheap, it has a great impact on subsequent processes and is prone to secondary water pollution; while vacuum filtration dust removal and other methods are often criticized due to large investment, high energy consumption, and inconvenient maintenance.

[0004] In the prior art, dust removal devices are often equipped with a dust suction mechanism to suck in dust-laden air for dust removal, and the dust suction mechanism is often an open structure with fixed suction force. The suction force during dust removal is generally fixed and unchanged. Although it can meet most dust removal needs, for environments with changing air pressure such as blasting, the dust suction mechanism with fixed suction force is difficult to filter dust-laden air in a timely and effective manner, resulting in excessive dust content in the air for a long time. Although there are also variable frequency dust suction mechanisms in the prior art, which increase the suction force by increasing the motor speed of the dust suction mechanism to quickly remove dust, the cost of the variable frequency system is relatively high, resulting in its limited application.

[0005] In addition, the prior art mostly uses the technology of filtering and dust removal for mining dust. However, after the dust collector works for a long time, too much dust will accumulate on the filter, and the current filter is inconvenient to clean. After long-term use, it will seriously affect the dust removal efficiency of the dust collector. For this reason, the prior art has a suction fan blade arranged on the motor output shaft fixed inside the dust collector, and a filter is arranged in front of the suction fan blade, and then a reciprocating mechanism is arranged on the motor output shaft, and a scraper connected to the reciprocating mechanism is arranged at the filter, so that the scraper is driven by the motor through the reciprocating mechanism to reciprocate and clean the filter, and a storage box is arranged under the filter to collect the dust that falls after cleaning, thereby improving the dust removal efficiency. However, if the dust that falls into the storage box is not cleaned in time after shutdown, when the fan is started again for dust removal, the dust inside the storage box will be scattered near the filter with the wind, thus affecting the dust removal effect; at the same time, when vacuuming, there is air circulation on the filter and there is a certain suction force. Therefore, when the filter dust is cleaned, the cleaned dust is difficult to fall smoothly into the storage box and is repeatedly adsorbed on the filter, which not only further affects the dust cleaning effect, but also accelerates the wear between the scraper and the filter. In addition, there is also a dust collector with an air inlet duct on the side of the box, and a filter, partition, and water collection tank are arranged in the box. The gas that needs to be dusted is transmitted into the box through the air inlet duct, and then the filter is used for preliminary dust removal. Then, the gas that needs to be dusted is further dusted by controlling the water pump to spray water, and finally the clean air is discharged. However, after a long period of filtration, a large amount of dust and impurities will accumulate on the filter, affecting the filtration efficiency. Moreover, the wet dust and impurities accumulated on the filter are easy to fall off after the thickness increases. The large pieces of dust and impurities that fall off are easy to cause the pipes in the box to be blocked, thus affecting the normal dust removal of the dust collector. In addition, the dust is not completely filtered through the filter and sprayed for secondary dust removal. Some fine dust particles are still difficult to be effectively captured and are discharged into the air to form pollutants that float for a long time. Of course, there are also ways to achieve the effect of dust removal by passing the dust into a solution and washing it, but the dust-carrying air is easy to generate bubbles in the solution, resulting in poor dust washing effects. Moreover, the dust and impurities after dust washing are easy to adhere to the inner wall of the container, making it difficult to clean up later. Although there is a technical solution of providing a stirring mechanism in the container to break up bubbles to improve the dust washing effect, and also providing a scraper on the stirring mechanism that can abut against the inner wall of the container to clean the adhered dust and impurities, due to the long-term friction between the scraper and the inner wall of the container during the stirring process, not only the inner wall of the container and the scraper wear out quickly and need to be replaced frequently, increasing the maintenance workload, but the sliding friction between the scraper and the inner wall of the container also increases the workload of the stirring mechanism, resulting in increased electricity costs.

[0049] The working principle and working process of the present invention:

[0050] like Figures 1 to 6As shown, before dust removal, it is necessary to check the overall condition of the dust removal device of the present invention to ensure that it can work normally. When dust removal, first place the dust removal device of the present invention at the mining site, start the dust suction fan 109 to drive the fan blades 110 to rotate to achieve dust suction, and use the rotating motor Ⅰ102 to drive the bevel gear 103 to rotate, the rotating bevel gear 103 is meshed with the bevel gear ring 104, and the bevel gear ring 104 drives the sealing baffle 106 to rotate under the meshing support of the gear 105, and the size of the dust suction opening is controlled by adjusting the rotation angle of the sealing baffle 106, thereby adjusting the size of the dust suction wind force; at the same time, by adjusting the sealing baffle 106 to close each other, the exhaust pipe 101 can be closed, which is convenient for protecting the dust suction fan 109. According to the needs, by starting the rotating motor II 116 to drive the rotating gear 117 to rotate, and by using the meshing between the meshing gear ring 114 and the rotating gear 117, the connecting elbow 112 and the rotating sleeve 113 are rotated, thereby changing the air inlet direction of the exhaust pipe 101 to achieve dust collection in different directions, effectively improving the efficiency of dust collection.

After a period of dust removal, the opening and closing motor 212 is controlled to drive the opening and closing gear 213 to rotate, and the opening and closing gear 213 is meshed with the opening and closing toothed disk 214. Under the guidance of the spiral groove 215 of the opening and closing toothed disk 214, the sliding connecting rod 216 drives the cleaning frame 217 to move. When the cleaning strip 219 of the cleaning frame 217 is in contact with the inner wall of the dust box 201, the inner wall of the dust box 201 can be cleaned under the drive of the rotating top seat 210. When the cleaning strip 219 of the cleaning frame 217 is separated from the inner wall of the dust box 201, the cleaning frame 217 can also fully stir the liquid inside the dust box 201.
