A mine blasting smoke suppression device

Abstract

The present invention belongs to the technical field of mine blasting dust removal, and discloses a mine blasting smoke suppression device, which includes a left support. Liquid storage shells are fixedly connected to both the left and right sides of the left support. A driving motor is fixedly installed on the front surface of the left support, and the output shaft of the driving motor is fixedly connected to a first driving wheel and a second driving wheel. In the present invention, the rotation of the rotating wheel drives the rotation of the rotating ring and the two filter rings. The rotating suction fan blades will suck the dust-laden gas generated by the explosion into the interiors of the fixed shell, the air guide shell, and the fan-shaped shell, and finally pass through the two rotating filter rings. The dust in the gas will be blocked in the filter rings. The dust-removed gas enters the air guide ring, and finally passes through the connection holes and enters the space between the two filter rings, thereby bringing down the dust on the filter rings and discharging it from the air outlet plate, thus solving the problem that the existing filter screen will be blocked after long-term operation. If not dealt with in time, it will reduce the filtration efficiency and even fail to achieve the dust removal effect.

Description

Technical Field

[0001] The invention belongs to the technical field of mine blasting dust removal, and in particular relates to a mine blasting smoke suppression device. Background Art

[0002] Mine blasting is the use of explosives to break up rock mass. It is currently the most effective and widely used means of rock excavation and stripping in the mining process. The smoke after mine blasting contains a large amount of toxic and harmful gases. The mine after blasting needs to be ventilated for a long time before it can be used normally. The mine blasting smoke suppression device is a device or system specially designed to reduce and control the harmful gases, dust and other pollutants generated after blasting in the mine. In a closed mine environment, effective smoke suppression measures are essential to protect the health of miners, improve the quality of the working environment and ensure safe production.

[0003] When the existing filter device is used to filter the smoke generated by mining blasting, due to the large amount of dust generated by mining blasting, the filter will be clogged after a period of work. If it is not handled in time, the filtering efficiency will be reduced, and even the dust removal effect will not be achieved. In addition, the existing method of cleaning the filter is to disassemble and wash the filter, which is time-consuming and laborious to maintain, and the maintenance method is relatively cumbersome.

[0012] 1. The present invention drives the motor to rotate the driving wheel 1 and the driving wheel 2, and the driving wheel 2 drives the adjusting transmission wheel and the rotating shaft to rotate through the driving belt. The rotation of the rotating shaft causes the rotating wheel to rotate, and finally drives the rotating circle and the two filter rings to rotate.

[0013] 2. In the present invention, the gas enters the interior of the fan-shaped shell and passes through two rotating filter rings. The dust in the gas will be filtered and blocked in the filter rings. The toxic gas treatment liquid in the upper tube enters the upper atomization tube and is finally atomized and sprayed out, so that the toxic gas is absorbed and follows the gas into the air guide ring, and finally passes through the connecting hole into between the two filter rings, and drives the lower atomization tube to spray out dust inhibitor droplets to contact the filter rings on both sides. At the same time, the rotating atomization shell will spray the atomized dust inhibitor and the toxic gas treatment liquid into a uniform water curtain, thereby preventing the uninhaled dust and toxic gas from being discharged from the mine mouth.

[0014] 3. The present invention allows the filtered gas to pass through the connecting hole into between the two filter rings, and drives the lower atomizing pipe to spray dust inhibitor droplets to contact the filter rings on both sides, thereby bringing the dust on the filter rings down, and the dust inhibitor droplets will gather the dust on the filter rings into larger dust, thereby preventing the dust from being carried up again by the discharged airflow when being discharged. In addition, this automatic cleaning method for the filter ring blockage does not require the filter ring to be disassembled, and the filter ring only needs to be rotated downward during operation, and the cleaning interval is short, which further avoids the filter ring from being blocked.

[0029] Working principle:

[0030] Before using the present invention, the present invention is placed in the middle of a mine or a tunnel, with the gas guide shell 14 facing the blasting site, a proper amount of dust suppressant is placed inside the left liquid storage shell 2, and a proper amount of toxic gas treatment liquid is placed inside the right liquid storage shell 2;

[0031] When the present invention is used, the driving motor 3 works to rotate the driving wheel 1 4 and the driving wheel 2 18. The driving wheel 2 18 drives the adjusting transmission wheel 20 and the rotating shaft 19 to rotate through the driving belt 21. The rotation of the rotating shaft 19 causes the rotating wheel 22 to rotate, and finally drives the rotating ring 173 and the two filter rings 172 to rotate.

[0032] The driving wheel 1 4 rotates, and drives the transmission wheel 2 133 to rotate through the synchronous belt 2 136, thereby driving the main shaft 131 to rotate, and the suction fan blades 132, the transmission wheel 3 134, and the two atomizing shells 137 on the main shaft 131 will rotate accordingly, and the transmission wheel 3 134 drives the transmission wheel 1 8 and the rotating shaft 7 to rotate through the synchronous belt 2 136, and the rotating shaft 7 drives the connecting shaft 9 to rotate, so that the liquid in the two liquid storage shells 2 is sucked through the lower suction pipe 10 and pumped into the two upper liquid outlet pipes 11, and the dust inhibitor sucked on the left side is pumped into the lower tube 177 and the interior of the connecting tube 139, and the toxic gas treatment liquid sucked on the right side is pumped into the upper tube 176 and the interior of the connecting tube 139. The dust inhibitor and the toxic gas treatment liquid entering the connecting tube 139 will be atomized by the atomizing shell 137 and sprayed into the air. Since the atomizing shell 137 is driven to rotate by the main shaft 131, a uniform water curtain is formed;

[0033] The rotating suction blades 132 will suck the dust-containing gas and toxic gas produced by the explosion into the interior of the fixed shell 12 and the air guide shell 14, and move to the right along the spiral plate 16. During the process, the flow rate of the gas will gradually slow down. When the gas enters the interior of the fan-shaped shell 178, it will eventually pass through the two rotating filter rings 172. The dust in the gas will be filtered and blocked in the filter ring 172. The toxic gas treatment liquid in the upper tube 176 enters the upper atomization pipe 175 and is finally atomized and sprayed out, so that the toxic gas is absorbed and follows the gas into the air guide ring 179, and finally passes through the connecting hole into between the two filter rings 172, and drives the lower atomization pipe 175 to spray out dust inhibitor droplets to contact the filter rings 172 on both sides, thereby bringing the dust on the filter ring 172 down and discharging it from the air outlet plate 1710, thereby ensuring that the filter rings 172 on both sides are not blocked by dust.
