Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not intended to limit the present invention.

Example 1:

As shown in the figure, a dust removal device for crushing refractory materials includes a dust collector 5 and a fan 6. An air curtain 9 is set on the feed port 1 of the crusher to form a channel, and only one part of the feed is reserved. On the side, the air curtain 9 is fixed on the discharge port 1 of the crusher through the bracket. The air curtain 9 is set to a certain height, but it cannot be too high. 30-50cm is the most suitable distance. The air curtain 9 is connected to the Fan 6, a certain wind pressure is provided by the fan. The discharge port 2 of the crusher is provided with a dust hood 4 to absorb the dust generated at the discharge port 2. Specifically, the dust hood 4 is connected to the dust collector 5 through an air duct. The dust collected in the dust collector can finally be placed in the In the crushed material of the crusher, the dust collector 5 is connected to the fan 6 through the air duct to be powered by the fan. Another optimized option is to set the air curtain 9 on both sides, located on both sides of the feeding port 1, and the other An arc-shaped baffle 11 is provided on the side. One of the baffles of the arc-shaped baffle 11 is its blocking function, and the other function is to make the wind form a vortex this time, so as to limit the dust in the air curtain 9 . The device uses a fan to recycle the air to form a balanced system of dust suction and air discharge, which can save resources and optimize control.

Example 2:

On the basis of the above-mentioned embodiment, in this embodiment, in order to prevent the wind pressure generated by vacuuming from being greater than the air output volume of the air curtain 9, thus causing the wind pressure of the fan 6 to be too large, the air outlet duct 8 is provided with a No. One pipe 7, the first branch pipe 7 is provided with a solenoid valve and a pressure sensor. When the pressure in the pipe reaches a certain level, the solenoid valve opens to exhaust air to the outside.

Example 3:

On the basis of the above-mentioned embodiment, in this embodiment, in order to better allow the dust to enter the crusher, the air curtain 9 is provided with a nozzle 10 which is connected to the air outlet duct 8, and the particles ejected by the nozzle 10 carry the dust together. Entering the crusher, one part of the wind settles in the crusher, and the other is absorbed and removed by the dust hood 4 through the discharge port 2 .

Example 4:

On the basis of the above-mentioned embodiment, in this embodiment, the spray head 10 cannot be sprayed all the time, which is more likely to raise dust. Therefore, a pulse solenoid valve is arranged on the pipeline from the spray head 10 to the air outlet pipe 8 for pulse spraying.

Example 5:

On the basis of the above embodiment, in this embodiment, the crushed raw materials are most dusty at the moment of discharge, and dust is still produced within a certain distance of conveying. Therefore, at the discharge port 2 of the crusher A conveyor belt 3 is provided at the place, and a dust cover 4 is provided on the conveyor belt 3 .

Example 5:

On the basis of the above-mentioned embodiment, in this embodiment, in order to prevent additional dust, the nozzle 10 is oriented toward the feeding port 1 leading to the crushing place, so that the dust generated at the feeding port 1 is restricted by the air curtain 9 Within a certain range, the spray head 10 is carried into the crusher. At the same time, the spray head 10 and the arc-shaped baffle 11 are adapted to each other to form a vortex, and then rolled into the crusher.
