[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0030] Embodiment 1

[0031] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a centrifugal dust removal device for mine stone materials, including a processing chamber 1 and a centrifugal dust removal mechanism 6. One side of the processing chamber 1 is fixedly installed with a feeding mechanism 4. The feeding mechanism 4 sequentially includes a parallel section 401, a rotary section 402, and an inclined section 403 in the feeding order. The inclined section 403 is inserted into the processing chamber 1. The other side of the processing chamber 1 is provided with a discharge port 101. The front of the processing chamber 1 is fixedly installed with a dust collection hood 3. A plurality of air inlets 102 are inserted and fixed on the back of the processing chamber 1. The plurality of air inlets 102 are equidistantly distributed on the back of the processing chamber 1. The projection of the inlet of the dust collection hood 3 on the back of the processing chamber 1 covers the plurality of air inlets 102. A vibrating screen 5 is fixedly installed in the processing chamber 1. The vibrating screen 5 is a common device on the market. The vertical height of the vibrating screen 5 in the processing chamber 1 is lower than the lowest height of the inclined section 403. The vibrating screen 5 penetrates through the discharge port 101. A plurality of balance brackets 2 are fixedly installed below the processing chamber 1. The plurality of balance brackets 2 sequentially include a sleeve 201, a plug rod 202, and a stable foot 203 from top to bottom. A thread is provided in the sleeve 201. The plug rod 202 is threadedly installed in the sleeve 201. The lower end of the plug rod 202 is fixedly connected to the stable foot 203. The stable foot 203 is disk-shaped. Parallel through holes 2021 are provided at a position of the plug rod 202 close to the stable foot 203.

[0032] Generally speaking, the ground of the mine is not all flat; the stone materials in the mine are conveyed out through a belt conveyor. A balanced running belt conveyor will not cause excessive dust to scatter from the stone materials. However, when the stone materials leave the belt conveyor, more dust will be generated. To address such problems, a balance frame 2 is added under the treatment chamber 1. The stabilizing feet 203 of the balance frame 2 are placed on the ground. A rod-shaped object can be passed through the through-hole 2021 of the insertion rod 202, so that the insertion rod 202 can move up and down by rotation within the sleeve 201. In cooperation with the threaded connection between the insertion post and the sleeve 201, the height of the treatment chamber 1 can be adjusted to adapt to complex working conditions. During use, the height of the treatment chamber 1 is adjusted through the balance frame 2, so that the belt conveyor is inserted into the parallel section 401 of the feeding mechanism 4. The stone materials leave the belt conveyor and enter the rotary section 402, and then fall onto the vibrating screen 5 from the inclined section 403. First, the length of the parallel section 401 limits the dust generated by the stone materials from floating into the external environment, and the setting of the rotary section 402 reduces the speed of the air containing dust to further prevent dust generated during feeding from causing secondary pollution to the environment. The cooperation of a number of air inlets and the dust collection hood enables the air flow in the treatment chamber 1, attracting the dust-containing air of the feeding mechanism 4 into the treatment chamber 1, further reducing the floating of dust.

[0033] Embodiment 2

[0034] Please refer to Figure 1 、 Figures 4 to 6 As shown in [relevant figures] (not shown here), the present utility model provides a technical solution: a centrifugal dust removal device for mine stone materials. One side of the dust collection hood 3 away from the treatment chamber 1 is inserted into the centrifugal dust removal mechanism 6. The centrifugal dust removal mechanism 6 successively includes an air outlet 601, a treatment section 604, a dust collection section 602, and a funnel section 603 from top to bottom. The shape of the treatment section 604 is funnel-shaped. The dust collection hood 3 is inserted into the treatment section 604 of the centrifugal dust removal mechanism 6 near the inner wall of the treatment section 604. On the inner side surface of the dust collection section 602, a first closing cover 9 and a second closing cover 11 are respectively hinged. The dust collection section 602 is a hollow cylinder. The first closing cover 9 and the second closing cover 11 have the same shape and size and are adapted to the inner diameter of the dust collection section 602. The first closing cover 9 is located above the second closing cover 11. An electric telescopic rod 10 is hinged below the first closing cover 9. The end of the electric telescopic rod 10 away from the first closing cover 9 is hinged to the dust collection section 602. A number of return springs 12 are fixed below the second closing cover 11. The ends of the return springs 12 away from the second closing cover 11 are fixed to the funnel section 603. When not working, the first closing cover 9 is open, and the second closing cover 11 closes the dust collection section 602. A normally open button 13 is fixedly installed on the inner side surface of the dust collection section 602. The position of the normally open button 13 is at the same level as the hinge joint of the second closing cover 11 and the dust collection section 602. The normally open button 13 is electrically connected to the electric telescopic rod 10. A support plate 7 is fixedly connected to the outer side surface of the dust collection section 602. A number of triangular support feet 701 are fixedly installed below the support plate 7. A collection box 8 is placed below the funnel section 603.

[0035] When not working, the second closing cover 11 remains horizontal under the action of several return springs 12. The closed dust collection section 602 ensures the normal operation of the centrifugal dust removal mechanism 6. The second closing cover 11 presses the normally closed button 13, making the electric telescopic rod 10 in its original length. At this time, the first closing cover 9 does not affect the falling of dust; when working, the dust-containing air flow is introduced into the treatment section 604 of the centrifugal dust removal mechanism 6 from the dust collection hood 3. Under the action of the rotating air flow, the dust is thrown out and falls onto the inner wall of the treatment section 604, and then falls into the dust collection section 602 under the action of gravity. As the dust accumulates, the return spring 12 is compressed, the second closing cover 11 deviates from the horizontal position, and at the same time it disengages from the normally closed button 13. The electric telescopic rod 10 is powered on and works to push the first closing cover 9 to the horizontal position to close the dust collection section 602 again (it is necessary to ensure that the amount of dust that compresses the return spring 12 and makes the second closing cover 11 deviate from the horizontal does not affect the operation of the first closing cover 9). During the operation of the electric telescopic rod 10, the dust in the dust collection section 602 plays a sealing role. When the dust on the second closing cover 11 falls into the collection box 8, the return spring 12 plays a role to push the second closing cover 11 to the horizontal position to realize the closing of the dust collection section 602. The second closing cover 11 presses the normally closed button 13 to cut off the power supply of the electric telescopic rod 10 and make it return to its original length; seamless switching is realized throughout the process, the dust collection section 602 is completely closed throughout the process, avoiding the influence on the centrifugal dust removal work, and reducing the use of labor compared with the ash discharge valve driven by the motor; the triangular support feet 701 and the collection box 8 are both placed on the ground.

[0036] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
