Description of the drawings:
fig. 1 is a schematic structural diagram relating to the present invention.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, the present invention relates to a bone material transferring, feeding and dedusting mechanism, which mainly comprises a material inlet 1 of a docking device, wherein the material inlet 1 refers to a material inlet of a device used for receiving bone material, such as a blender, a mixing mechanism, etc. In the prior art, all the devices for receiving aggregates are provided with feeding ports, which are not described herein.
Specifically, be equipped with dust collecting cavity 2 on the opening edge of pan feeding mouth 1, dust collecting cavity 2 top is stacked has negative pressure chamber 3, negative pressure chamber 3 is through bleed device 4 and pipeline 41 and dust collecting cavity 2 intercommunication, 3 internal surface evenly distributed in negative pressure chamber has a plurality of negative pressure mouth 30, 2 internal surface evenly distributed in dust collecting cavity has a plurality of gas vents 20, make negative pressure chamber 3 and negative pressure mouth 30 produce the negative pressure through arousing device 4, carry dust absorption back to dust collecting cavity 2 in, dispose filter media 21 in the dust collecting cavity 2, and filter media 21 covers in gas vent 20 inboard, clean gas is discharged from gas vent 20.
The device 4 can be caused to adopt negative pressure equipment such as a fan, the filter material 21 can be a dust removal filter screen or a medium efficiency filter screen, after dust is carried by high-speed wind flow and enters the dust collection cavity 2, gas is discharged to the exhaust port 20, the dust is collected by being blocked by the filter material 21, and under the continuous blowing of the high-speed wind flow, the dust on the surface of the filter material 21 can also fall and precipitate downwards.
The dust collection cavity 2 is of an inverted cone ring shape with a large upper part and a small lower part, the negative pressure cavity 3 is of a cone ring shape with a small upper part and a large lower part, the inner diameter of an opening at the upper part of the negative pressure cavity 3 is smaller than that of the feeding opening 1, a necking cavity is formed above the feeding opening 1, the opening above the cavity (namely the upper part of the negative pressure cavity 3) is adaptive to the feeding range of aggregate, the aggregate enters from the upper part of the negative pressure cavity 3, after feeding, dust can be raised above the feeding opening 1, the raised dust is located in the necking cavity, and under the dust collection operation of the negative pressure opening 30, the dust is not easy to continue to be raised above the negative pressure cavity 3.
The dust collection chamber 2 below is equipped with annular dust fall chamber 5, the dust fall 5 bottom in chamber is for being the inclined plane, and dispose the dust exhaust port 50 that runs through dust fall chamber 5 in the lower extreme on inclined plane, can gather in dust fall 5 bottoms in chamber 2 that gathers materials when the dust that scatters, the distinguished and admirable parallel wind that tends to in the dust collection chamber 2 flows, can not play the effect of raising to the dust that subsides, consequently, the dust after subsiding can be in 5 bottoms of inclined dust fall chamber active and slide to dust exhaust port 50 department, accessible dust exhaust port 50 discharges.
The air guide rail 201 is arranged at the air outlet 20, and the air guide rail 201 inclines towards the direction of the material inlet 1, so that the exhausted clean air acts on the material inlet 1, and the exhausted air can form a weak air curtain around the material inlet 1, thereby having a function of inhibiting dust.
The horizontal distance of the negative pressure port 30 relative to the feeding port 1 is smaller than that of the exhaust port 20, namely the negative pressure port 30 is close to the top of the negative pressure cavity 3 and is closer to the edge of the aggregate blanking range, and a small amount of dust which penetrates through the air curtain and is scattered close to the aggregate blanking edge can be better absorbed by the negative pressure port 30 in the rising process under the inhibition of the air curtain formed by the exhaust port 20, so that the raised dust is prevented from continuously overflowing.
The material collecting cavity 2 and the negative pressure cavity 3 are annular bodies, a plurality of air entraining devices 4 can be arranged on the negative pressure cavity 3, and enough negative pressure value can be generated in the negative pressure cavity 3.
