[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 As shown, an intelligently controlled phosphate mine ventilation device comprises an air inlet pipe 1; a filter pipe 2 is fixedly connected to the side end of the air inlet pipe 1; a blocking net 3 is fixedly connected to the inner wall of the air inlet pipe 1; an air pump 7 is fixedly connected to the inside of the filter pipe 2; a filter net 4 is fixedly connected to the inner wall of the air inlet pipe 1; a spiral blade 5 is rotatably connected to the inside of the air inlet pipe 1; a cleaning brush 6 is fixedly connected to the side end of the spiral blade 5, and a filter net 4 is provided on one side of the cleaning brush 6.

[0021] During operation, negative pressure is generated by the vacuum pump 7 to absorb gas. Gas can enter from the air inlet pipe 1, and firstly, the gas is filtered through the object blocking net 3 to prevent large and light objects from being sucked into the air inlet pipe 1. When the gas enters the air inlet pipe 1, the spiral blade 5 will rotate, and the rotation of the spiral blade 5 will then rotate the cleaning brush 6. The dust in the gas can be filtered through the filter net 4. After long-term filtration, the dust will accumulate on the surface of the filter net 4. The rotation of the cleaning brush 6 can clean the dust on the surface of the filter net 4, reduce the situation where dust is blocked on the surface of the filter net 4, ensure the speed of gas flow, and reduce the frequency of maintenance and replacement of the filter net 4.

[0023] The rotation of the cleaning brush 6 will cause the magnet block 10 to rotate together. When the magnet block 10 rotates to the vicinity of the vibration block 13, the magnet block 10 absorbs the vibration block 13 through the magnetic attraction to slide toward the filter 4, so that the vibration block 13 hits the filter 4 to generate vibration. The vibration of the vibration block 13 can cause the dust blocking the filter 4 to fall off. A plurality of groups of vibration blocks 13 are provided inside the air inlet duct 1 to reduce dust accumulation.

[0024] A filter box 9 is installed inside the filter tube 2 ; filter cotton 17 is fixedly connected inside the filter box 9 ; and multiple groups of filter blocks 19 are fixedly connected inside the filter cotton 17 .

[0025] After passing through the vacuum pump 7, the gas will enter the filter cotton 17 inside the filter box 9. The filter cotton 17 is made of filter cotton material. The gas can be filtered again through the filter cotton 17 to improve the gas purification effect. Activated carbon is arranged inside the filter block 19. When other particles come into contact with the filter block 19, the activated carbon in the filter block 19 can absorb impurities in the gas and improve the gas filtering effect.

[0027] The dust on the filter screen 4 will fall downward after being cleaned by the cleaning brush 6, preventing the dust from accumulating on the inner wall of the air inlet pipe 1 and affecting the flow rate of the gas. The dust will fall along the sand guide groove 14 to the internal storage of the collection box 15, which is convenient for the staff to handle it uniformly.

[0028] A storage slot 16 is provided inside the filter cotton 17 ; a positioning magnet plate 18 is fixedly connected to the top of the filter box 9 .

[0029] Impurities in the gas can be blocked and then fall into the storage tank 16, which is convenient for collecting the impurities and then processing them uniformly. The filter cotton 17 needs to be replaced regularly. The filter box 9 can be installed into the inside of the filter tube 2 by positioning the magnet plate 18. The filter box 9 can be installed and disassembled by positioning the magnet plate 18.

[0030] The interior of the filter tube 2 is fixedly connected with sound insulation cotton 8, and the inner wall of the sound insulation cotton 8 is installed with an air pump 7.

[0031] The vacuum pump 7 generates a lot of noise during operation. Sound insulation cotton 8 is arranged around the vacuum pump 7. The sound insulation cotton 8 can absorb the noise and reduce the diffusion of the noise, thereby providing a good working environment for nearby workers.

[0032] The working principle of the utility model is as follows: when working, the vacuum pump 7 generates negative pressure to absorb gas. The gas can enter from the air inlet pipe 1, and firstly, the gas is filtered through the blocking net 3 to prevent large and light objects from being sucked into the air inlet pipe 1. When the gas enters the air inlet pipe 1, the spiral blade 5 will rotate, and the rotation of the spiral blade 5 will then rotate the cleaning brush 6, and the dust in the gas can be filtered through the filter net 4. After long-term filtration, the dust will accumulate on the surface of the filter net 4. The rotation of the cleaning brush 6 will clean the dust on the surface of the filter net 4, reducing the dust clogging in the The surface of the filter 4 is also guaranteed to ensure the speed of gas flow, reducing the frequency of maintenance and replacement of the filter 4; when the cleaning brush 6 rotates, the magnet block 10 will rotate together. When the magnet block 10 rotates to the vicinity of the vibration block 13, the magnet block 10 absorbs the vibration block 13 through the magnetic attraction to slide toward the filter 4, so that the vibration block 13 hits the filter 4 to generate vibration. The vibration of the vibration block 13 will cause the dust blocked on the filter 4 to fall off. Multiple groups of vibration blocks 13 are provided inside the air inlet 1, which can reduce the accumulation of dust; the dust on the filter 4 is cleaned by the cleaning brush 6 After cleaning, it will fall downward to prevent dust from accumulating on the inner wall of the air inlet pipe 1 and affecting the flow rate of the gas. The dust will fall along the sand guide groove 14 to the internal storage of the collection box 15, which is convenient for the staff to handle it uniformly; the vacuum pump 7 will generate a lot of noise during operation. Sound insulation cotton 8 is arranged around the vacuum pump 7. The sound insulation cotton 8 can absorb the noise and reduce the diffusion of the noise, thereby providing a good working environment for nearby staff; after passing through the vacuum pump 7, the gas will enter the filter cotton 17 inside the filter box 9. The filter cotton 17 is made of filter cotton material. The filter cotton 17 can filter the gas again to improve the gas purification effect. Activated carbon is arranged inside the filter block 19. When the gas contacts the filter block 19, the activated carbon can adsorb impurities in the gas through the filter block 19 to improve the gas filtering effect. The impurities in the gas can be blocked and then fall into the storage tank 16, which is convenient for collecting the impurities and then processing them uniformly. The filter cotton 17 needs to be replaced regularly. The filter box 9 can be installed into the inside of the filter tube 2 by positioning the magnet plate 18. The filter box 9 can be installed and disassembled by positioning the magnet plate 18.
