[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0031] Embodiment one
[0032] Based on the problem that the existing prior art has low removal efficiency for fine dust with small particle size and is difficult to meet the increasingly stringent environmental protection requirements, the embodiment provides a strong dust removal device for rare earth metal processing, please refer to Figures 1-5 , the embodiment provides a strong dust removal device for rare earth metal processing, which can improve the removal efficiency of dust. The strong dust removal device for rare earth metal processing comprises a water washing tower 2 installed at the rear side of a crusher 1, a water washing and dust removal mechanism 3 for removing dust generated in the crushing process of rare earth metal is arranged on the water washing tower 2, a sealed conveying mechanism 4 for preventing dust from diffusing caused by conveying the crushed rare earth metal is arranged on the crusher 1, one of the rotating shafts is rotated by the motor on the crusher 1, the meshing gear on the rotating shaft drives the rotating shaft on the other meshing gear to rotate, thereby driving the crushing knife groups on the two rotating shafts to rotate to crush the rare earth metal ore, and then the water washing and dust removal mechanism 3 is used to wash and remove the dust generated in the crushing process of the rare earth metal ore, so as to improve the removal efficiency of the dust, and the sealed conveying mechanism 4 is used to seal and convey the crushed rare earth metal, so as to avoid dust diffusion and environmental pollution.
[0033] Since the existing prior art has low removal efficiency for fine dust with small particle size and is difficult to meet the increasingly stringent environmental protection requirements, therefore, the device is provided with a water washing and dust removal mechanism 3, the water washing and dust removal mechanism 3 comprises an air extractor 31 installed on the back of the crusher 1, an inlet dust pipe 32 extending into the water washing tower 2 is installed on the air outlet interface of the air extractor 31, a water pump 33 is installed on the water washing tower 2, a three-way pipe 34 is installed on the water inlet interface of the water pump 33, a water supply pipe 35 extending into the water washing tower 2 at the top is installed on the water outlet interface of the water pump 33, an atomizing nozzle 36 is installed on the top of the water supply pipe 35, and a dispersed dust treatment assembly 37 for secondary treatment of the dispersed and floating fine dust particles is arranged in the water washing tower 2. The dust generated in the crushing process in the crusher 1 is sucked into the water washing tower 2 through the inlet dust pipe 32 by starting the air extractor 31, at this time, the water pump 33 is started, the water source is sucked into the water supply pipe 35 through the three-way pipe 34, and is atomized and sprayed out through the atomizing nozzle 36, so as to wash and purify the dust, so that it is settled at the bottom of the water washing tower 2, and the dust removal and purification work is completed.
[0034] Since part of the dust with light mass may escape after contacting with the water mist, the device is further provided with an escaping dust treatment assembly 37. The escaping dust treatment assembly 37 comprises a cyclone plate 371 installed on the inner wall of the water washing tower 2 and located above the atomizing nozzle 36, and an annular pipe 372 fitted to the inner wall of the water washing tower 2 is installed above the cyclone plate 371. The bottom of the annular pipe 372 is provided with overflow holes 373 equidistantly and penetratingly formed in a ring shape. A communication pipe 374 communicating with the annular pipe 372 is installed on the water feeding pipe 35. When part of the escaping dust and water mist particles pass through the cyclone plate 371, the particles are guided to rotate in the upfloating air flow. Under the action of centrifugal force, the dust and water mist particles with small particle size in the air flow are thrown to the inner wall of the water washing tower 2, so as to further remove the dust with small particle size. At this time, the water flow is introduced into the annular pipe 372 through the communication pipe 374, and flows down along the inner wall of the water washing tower 2 through the overflow holes 373, so as to form a water curtain flowing downward on the tower wall, thereby flushing the dust adhered to the inner wall of the water washing tower 2.
[0035] The dust inlet pipe 32 is located below the atomizing nozzle 36, and an air flow uniform distribution plate 38 is installed between the dust inlet pipe 32 and the atomizing nozzle 36. Through the setting of the air flow uniform distribution plate 38, the dust air flow introduced into the water washing tower 2 is uniformly divided, the contact area of the dust and the water mist is increased, and the removal efficiency of the dust is improved.
[0036] If the clean water source is continuously used to wash and purify the dust, a large amount of water resource will be wasted, and the cost of the enterprise will be increased. Therefore, one end of the tee pipe 34 is extended into the water washing tower 2, and the tee pipe 34 is located below the dust inlet pipe 32. A filter cage head 39 is installed at the interface of the tee pipe 34. A liquid level sensor 310 is installed on the inner wall of the water washing tower 2 between the tee pipe 34 and the dust inlet pipe 32. When the water level accumulated in the water washing tower 2 is higher than the liquid level sensor 310, the water supply from the outside is stopped. The water in the water washing tower 2 is pumped through the tee pipe 34 extended into the water washing tower 2 to wash and purify the dust, so as to realize the recycling use of the water resource and save the water resource. The filter cage head 39 is used to coarsely filter the water in the water washing tower 2, so as to avoid that the particles in the sewage block the atomizing nozzle 36.
[0037] Example Two
[0038] Since a large amount of dust is generated in the operation process of the broken rare earth metal, the environment is polluted. Therefore, based on the example one, a dust removal device 40 is further provided. Figures 1-5As shown, the device is also provided with a sealed conveying mechanism 4, which comprises a conveying pipe 41 mounted on the bottom of the crusher 1, a rotating shaft 42 rotatably connected in a rotating hole formed on the conveying pipe 41, a conveying auger 43 mounted on the rotating shaft 42, and a driving motor 44 for driving the rotating shaft 42 to rotate, mounted on the conveying pipe 41. A discharging pipe 45 extending into the conveying pipe 41 is mounted on the bottom of the crusher 1. The crushed rare earth metal falls into the conveying pipe 41 through the discharging pipe 45. At this time, the driving motor 44 is started to drive the rotating shaft 42 to rotate, thereby driving the conveying auger 43 to rotate and sealingly conveying the rare earth metal, so as to avoid dust diffusion and environmental pollution during operation.
[0039] The bottom of the crusher 1 is in a conical structure, and the top of the crusher 1 is provided with a feeding hopper 46, and the feeding hopper 46 is provided with a baffle 47 through a torsional spring shaft. When feeding, the weight of the ore presses the torsional spring shaft to rotate and extrude the torsional spring, thereby driving the baffle 47 to overturn and guide the ore into the crusher 1. Then, the torsional spring is reset under the elastic action of itself to drive the baffle 47 to reseal the feeding hopper 46, so as to avoid dust diffusion.
