Description
Technical Field
[0001] The utility model relates to the technical field of mine dust removal, in particular to safe dust reduction equipment for mines. Background Art
[0002] Mine dust is a general term for fine particles of solid matter such as rock dust and mineral dust generated by blasting, mechanical chiseling, cutting, friction and vibration during the mining process in mines. According to the causes of dust generation, it is divided into two categories: natural floating dust and productive dust. Natural floating dust refers to dust generated by geographical conditions and meteorological changes, such as wind sand, dust, etc. Due to the different particle sizes and weights of dust, the settling time in the air is also different. Generally, this kind of dust particles are large and settle quickly, and the human respiratory organs have a certain defense function against it. Productive dust refers to dust generated by mechanical or chemical actions of substances in the production process. Mine dust (referred to as mine dust) belongs to productive dust. It is generated in the mining process. The mine dust suspended in the air is also called floating dust, the settled mine dust is called fallen dust, and the mine dust with a free silicon dioxide content greater than 5% is called silica dust.
[0003] A large amount of dust will be generated during the mining process in the mine. In most cases, water sprinkling is used to reduce dust, but the water sprinkling adsorption method cannot completely adsorb the dust. Usually the dust content in the air is still greater than the normal range. The mine dust is different from the construction site dust. The mine dust contains some metal dust, and the metal dust will cause serious harm to the body when adsorbed by the construction workers. At the same time, some metal dust will explode after touching static electricity, causing safety accidents. For this reason, we propose a safe dust reduction equipment for mines. Utility Model Content

The setting of the guide mechanism 2 plays a role of drainage and can guide the flow of air. An atomizer is supported on the outside of the spray bracket 3, and the setting of the spray bracket 3 can perform large-scale dust reduction during use, so that the dust is adhered to the water mist and then falls. The setting of the guide sleeve 4 plays a role in discharging metal dust. A dust collecting bag can be arranged on the outside of the guide sleeve 4 to collect metal debris. The front of the drainage pipe 1 A guide sleeve 4 is fixedly installed at the back, and a rotating sleeve 11 and a support plate 12 are in contact with the inner side of the guide sleeve 4, and the outer side of the support plate 12 is in contact with the inner wall of the guide sleeve 4. The setting of the support plate 12 can effectively seal the inner side of the guide sleeve 4. In the process of the rotating sleeve 11 driving the support plate 12 to rotate, the rotation of the support plate 12 can continuously block the interval between the guide sleeve 4 and the drainage pipe 1, thereby preventing the inner cavity airflow of the drainage pipe 1 from being discharged in large quantities through the guide sleeve 4, thereby affecting the dust reduction efficiency. A support frame 5 and a first support block 6 are fixedly installed at the front and rear sides of the drainage pipe 1, respectively. The inner cavity of the first support block 6 is movably sleeved with a rotating shaft 7, and the left end of the rotating shaft 7 is movably sleeved in the inner cavity of the support frame 5.

At the same time, the supporting frame 5 can support the rotating shaft 7 to cooperate with the rotating shaft 7, so that the rotating shaft 7 drives the rotating sleeve 11 to rotate, and then drives the supporting plate 12 to rotate. The rotation of the rotating sleeve 11 and the supporting plate 12 is used to assist in the discharge of metal dust, which can effectively improve the efficiency and speed of dust reduction. The vertical section of the electromagnetic block 9 and the second supporting block 10 is fan-shaped, the vertical section angle of the electromagnetic block 9 is 270 degrees, and the vertical section angle of the second supporting block 10 is 90 degrees, so that the rotating sleeve 11 rotates and drives the supporting plate 12 to rotate, and then the cooperation of the supporting plate 12 and the rotating sleeve 11 will drive the metal dust particles to rotate, so that the metal dust is transported to the second supporting plate 12 on the back of the electromagnetic block 9.

In the process of air passing through the inner cavity of the drainage pipe 1, the electromagnetic block 9 is controlled to be energized to drive the motor 8 to start. The energization of the electromagnetic block 9 makes the electromagnetic block 9 magnetic, and the metal particles in the air are adsorbed to the electromagnetic block 9, and the metal powder The dust will be absorbed to the outside of the rotating sleeve 11, and then the drive motor 8 is controlled to start, and the output shaft of the drive motor 8 is used to drive the rotating shaft 7 to rotate. During the rotation of the rotating shaft 7, the rotating sleeve 11 will be driven to rotate, and the support plate 12 will be driven to rotate during the rotation of the rotating sleeve 11. Then, the cooperation between the support plate 12 and the rotating sleeve 11 will drive the metal dust particles to rotate, so that the metal dust is transported to the outside of the second support block 10 on the back of the electromagnetic block 9.
