Nowadays, in the coal industry, how to reduce environmental pollution in the process of coal mining, processing and utilization and achieve green, low-carbon and sustainable development has become an important trend in the development of the industry. In addition, with the development of green, low-carbon and sustainable development, the treatment of dust must be clean and environmentally friendly, and must not pollute the environment. Especially in factories, oil-rich pulverized coal will produce a lot of dust in the process of crushing and reproducing. In order to protect the environment and avoid air pollution, the raw materials in the entire production process will not fall to the ground, and water will not be used to avoid waste of water resources and environmental pollution. The dust includes impurities such as coal slag and dust. Only dust collectors are used for dust removal, and coal slag and dust cannot be separated, and they cannot be recycled. Therefore, it is necessary to design a device that can classify dust, recycle according to the size of dust particles, and clean the dust to achieve green, environmental protection, and no pollution to the environment.

DETAILED DESCRIPTION
[0016] The utility model will be further described below in conjunction with the accompanying drawings.
[0017] like Figures 1 to 3The oil-rich pulverized coal dust recovery and utilization device shown in the figure comprises a cyclone separator 1 and a dust recovery device 6. A dust inlet 2 is fixedly connected to the outside of the cyclone separator 1. In order to facilitate disassembly and maintenance, an auger conveyor 4 is fixedly connected to the bottom of the cyclone separator 1 through a flange. The auger conveyor 4 is driven by a first motor 5, and the output end of the first motor 5 is fixedly connected to the auger shaft. The other end of the auger conveyor 4 extends to the production line for repeated utilization. In order to prevent the dust from falling to the ground and polluting the environment, a shell is provided outside the auger conveyor 4 to wrap it. In order to enable the dust to be recycled for the second time and provide power for the cyclone separator 1, an induced draft fan 18 is fixedly connected to the air outlet at the upper end of the cyclone separator 1, and an air duct 3 is fixedly connected to the output end. The other end of the air duct 3 is fixedly connected to the dust recovery device 6, and a vertical downward partition plate 13 is provided on the side connected to the air duct 3 in the dust recovery device 6. The dust comes down from the left side of the device and enters the right side of the device for filtration. In order to completely filter the dust and exhaust clean air, A first filter plate 16 and a second filter plate 14 are horizontally arranged between the inner wall of one side of the dust recovery device 6 and the partition plate 13, and the first filter plate 16 is located above the second filter plate 14, and the bottoms of both sides of the first filter plate 16 and the second filter plate 14 are connected to the boss 10 through springs 11, and four groups of springs 11 and bosses 10 are arranged opposite to each other. The boss 10 is fixedly connected to the inner wall of the dust recovery device 6 and the partition plate 13. In order to facilitate the collection of dust adsorbed on the filter plate and the dust collecting plate 9 to the dust outlet, the first filter plate 16 is provided with a plurality of springs 11, and the second filter plate 14 is provided with a plurality of springs 11, and the boss 10 is provided with a plurality of springs 11, and the boss 10 is fixedly connected to the inner wall of the dust recovery device 6 and the partition plate 13. The filter plate 16 and the second filter plate 14 are fixedly connected to the bottom with a vibration motor 15, and the second filter plate 14 is fixedly connected to the bottom with a dust collection plate 9 pointing vertically downward. When the vibration motor 15 drives the second filter plate 14 to vibrate, the second filter plate 14 drives the dust collection plate 9 to vibrate at the same time, and the dust attached to it is shaken off to the dust outlet 8 at the bottom of the dust recovery device 6. In order to improve the recovery efficiency and accelerate the air circulation, an air outlet 19 is opened at the top of the dust recovery device 6, and an exhaust fan 17 is arranged below the air outlet 19.
[0018] It should be noted that in the present invention, an openable opening and closing door is hinged at the dust removal port 8 to facilitate dust collection and maintenance.
[0019] In order to facilitate the collection of dust in the dust outlet at the bottom of the dust recovery device 6 , a bracket 7 is fixedly connected to the bottom of the dust recovery device 6 .
[0020] In order to achieve a better dust filtering effect, the aperture of the first filter plate 16 is set to be smaller than the aperture of the second filter plate 14, so that the air passing through the first filter plate 16 does not contain dust.
[0021] In order to conveniently control the start and stop of the motor, a control box 12 is provided outside the dust recovery device 6 , and the exhaust fan 17 and the vibration motor 15 are both controlled by the control box 12 .
[0022] In order to control the on and off of the power supply to the dust collecting plate 9 and control the dust collecting time period, the dust collecting plate 9 is electrically connected to the control box 12 .
[0023] The specific working process of the utility model is as follows:
[0024] When dust containing dust and coal slag is sucked into the dust collector, in order to classify and recycle the dust, the dust inlet 2 is now connected to the dust collector, and all the dust containing coal slag and dust is sent into the cyclone separator 1, and the induced draft fan 18 is turned on to provide power for the cyclone separator 1. After screening by the cyclone separator 1, large particles of coal slag fall into the bottom dragon conveyor 4. By controlling the first motor 5 to start, the large particles of coal slag continue to be sent to the production line for processing to improve the utilization rate of raw materials. At this time, small particles of dust enter the dust recovery device 6 through the air duct 3 from the upper outlet, and the dust enters from the left side. At the same time, the dust suction plate 9 is energized and the exhaust fan 17 is turned on through the control box 12. The exhaust fan 17 rotates, and the dust first passes through the dust suction plate 9, and most of the dust is adsorbed on the dust suction plate 9, and then passes through the first filter The plate 14 filters and absorbs the remaining dust, and finally reaches the second filter plate 16. At this time, all the dust is filtered out, and the clean air is discharged from the air outlet 19 to complete the dust cleaning process. When the dust is collected to a certain extent, the exhaust fan 17 is turned off, and the power on the dust collection plate is disconnected at the same time. The vibration motor 15 is turned on through the control box. The vibration motor 15 drives the first filter plate 16 and the second filter plate 14 to start vibrating, and the second filter plate 14 drives the dust collection plate 9 to vibrate, thereby shaking off the adsorbed dust to the dust outlet 8 at the bottom of the dust recovery device 6 for collection, completing the dust recovery process. Dust recovery and utilization according to the above steps can better classify dust particles according to their particle size and recycle them according to their classification, which not only avoids waste of resources but also avoids environmental pollution.
