[0025] As Figure 1-Figure 6 The utility model provides a dust reduction device for environmentally friendly water circulation in the production of aluminum powder paste. It mainly collects the dust in the factory area first, and then uniformly sprays water to reduce dust on the recovered dust. Compared with the existing dust reduction system, the dust reduction effect of this product is better.

[0026] Example 1

[0027] A plurality of dust reduction boxes 1 are arranged on the top of the factory area, and the drainage mechanism 3 is used to introduce the external gas mixed with dust into the dust reduction box 1, and the dust reduction purpose is achieved by the dust reduction mechanism 2 arranged in the dust reduction box 1.

[0028] Specifically, the dust reduction mechanism 2 includes a spray pressure pipe 21, a water pump 22, a return pipe, and a water spray unit 23. The two ends of the water pump 22 are respectively connected to the spray pressure pipe 21 and the return pipe. The spray pressure pipe 21 extends into the dust reduction box 1. Several water spray units 23 are all connected to the section of the spray pressure pipe 21 located in the dust reduction box 1. The return pipe is connected to the dust reduction box 1 and is used to spray the water at the bottom of the dust reduction box 1 out from the water spray unit 23 again through the water pump 22, thereby achieving the purpose of water circulation and saving resources.

[0029] Furthermore, the water spray unit 23 specifically includes a bottom pipe 231, a top pipe 232, a jet outlet 233, a resistance rod 234, a rotating circle 235 and a stressed fan blade 236. The bottom pipe 231 is fixed and connected to the spray pressure pipe 21. A blocking rod is fixed inside the bottom pipe 231. A space for water to pass through is reserved between the blocking rod and the inner wall of the bottom pipe 231. The bottom shape of the top pipe 232 is the same as the end face shape of the space, so that the top pipe 232 is respectively fitted and slidably connected with the bottom pipe 231 and the side wall of the blocking rod. Because the height of the blocking rod is less than the height of the bottom pipe 231, when the water pump 22 pumps water into the bottom of the bottom pipe 231 at a certain pressure, the water pushes the top pipe 232 to move upward. When the top pipe 232 is not in contact with the blocking rod but still in contact with the bottom pipe 231, the water enters the top pipe 232 from the space and is sprayed out from the jet outlet 233 opened at the top of the top pipe 232.

[0030] A resistance rod 234 is fixed on the top pipe 232 , and the resistance rod 234 is used to interfere with the rotating circle 235 to prevent the top pipe 232 from flying out under water pressure.

[0031] A rotating circle 235 is rotatably connected to the top of the bottom tube 231 through a support rod, and a plurality of stressed fan blades 236 are obliquely fixed on the inner side of the rotating circle 235. The stressed fan blades 236 are located on the path of the water flow ejected from the jet port 233. Preferably, the water flow ejected from the jet port 233 hits the stressed fan blades 236 along the vertical direction of the corresponding stressed fan blades 236, so that the impact force is maximized. The water flow hits the stressed fan blades 236, which, on the one hand, drives the stressed fan blades 236 to rotate, and on the other hand, the water flow will generate water mist due to the impact. Furthermore, the rotating stressed fan blades 236 can also improve the purpose of breaking up the water flow, so that the broken up water flow can achieve dust reduction treatment for the dust in the dust reduction box 1.

[0032] Furthermore, a plurality of drainage blades 237 are fixed on the outer side of the rotating circle 235. The airflow input from the negative pressure port 31 into the dust reduction box 1 and the rotating circle 235 are eccentrically arranged so that the airflow can drive the drainage blades 237 to drive the rotating circle 235 to rotate, thereby improving the efficiency of breaking up the water flow, so that the airflow can carry more water droplets to reduce dust.

[0033] Example 2

[0034] On the basis of Example 1, the drainage mechanism 3 includes a negative pressure port 31 and a fan 32. The negative pressure port 31 connected to the dust reduction box 1 opens downward so that the dust produced by the aluminum powder paste production equipment below can be sucked into the dust reduction box 1. The fan 32 and the negative pressure port 31 are respectively installed at the two ends of the dust reduction box 1. The fan 32 uses negative pressure to allow the negative pressure port 31 to suck the dust-laden air into the dust reduction box 1. In the process of moving from one end of the dust reduction box 1 to the other end, the dust will be subjected to dust reduction treatment by the dust reduction mechanism 2. Centralized treatment is conducive to the efficient sedimentation of dust.

[0035] Example 3

[0036] On the basis of Example 1 and Example 2, an anti-blocking mechanism 4 is further provided, and the anti-blocking mechanism 4 includes a filter screen 41, a leakage screen 42, a motor 43 and a cam 44. In order to optimize the water flow quality recovered by the return pipe, the filter screen 41 is fixed to the bottom of the dust reduction box 1 to separate the aluminum powder and water. The leakage screen 42 and the filter screen 41 are elastically slidably connected, and the brush on the leakage screen 42 can clean the aluminum powder on the filter screen 41. The motor 43 is installed on the dust reduction box 1, and the output shaft of the filter screen 41 is fixedly connected to the cam 44. The cam 44 is used to repeatedly push the leakage screen 42 to make reciprocating linear movements, so that the brush on the leakage screen 42 repeatedly rubs the aluminum powder on the filter screen 41 to prevent the reduction of the aluminum powder on the filter screen 41 from blocking the filtering effect of the filter screen 41.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
