Problems solved by technology

[0002] The ore transportation is involved in the mining process, and the ore is prone to fall and dust at the transitional transfer point. In order to eliminate the dust, a water spray device is usually installed above the drop position to achieve dust reduction by spraying water, but this kind of dust reduction The method is to wet the dust, and the wet dust will be mixed into the ore again. Because the ore is water-absorbent, there will be a hidden danger of dust during the subsequent ore transfer, and the existing dust suppression device itself is easy to accumulate a large amount of dust, which will cause Blockage and drive sticking phenomenon

Embodiment 1

[0029] see Figure 1-3 , a jet-type anti-blocking and dust-reducing device used in mine development. This dust-reducing device is used to be placed at the front end of the belt conveyor used for mineral material transfer, that is, the position of the blanking end, and can be placed under the belt of the blanking material. It is a dust-affected area. The dust suppression device includes a horizontal bearing shaft 1, a water storage pipe 2, a water tank 3 and a bearing plate 4, wherein the bearing plate 4 plays a role in supporting the entire dust suppression device. The middle connecting round platform 11 and the end connecting disc 12 are distributed on the same axis. The number of the end connecting discs 12 is two and located on both sides of the middle connecting round platform 11. The two ends of the water storage pipe 2 are blind ends and one end is fixedly connected. There is a connecting shaft 21 fixedly connected to the outer wall of the end connecting disk 12, and the...

Embodiment 2

[0031] see image 3, and the difference from Embodiment 1 is that the outer wall of the water storage pipe 2 is fixedly connected with the watering can 6 close to the outer flow hole 23, the sprinkling mouth of the watering can 6 faces the outer wall of the water storage pipe 2, and the position of the watering can 6 is relatively The evenly distributed water storage pipes 2 are set outwards. Specifically, the outer wall of the water storage pipe 2 is fixedly provided with a connecting column 25. The watering pot 6 is spherical and has a water sprinkling hole 61 connected to the inner cavity on it. One end gap of the post 25 passes through the sprinkling hole 61 and is fixedly connected with the inner surface wall of the watering can 6, thus, when the large end of the water storage pipe 2 is submerged in the water, the watering can 6 is used for watering, when the water storage pipe 2 During the movement of the big end to the highest position, the water outlet of the watering ...

Embodiment 3

[0033] see Figure 4 , the difference with Embodiment 1 is that the outer wall of the air jet tube 22 is fixedly provided with an air jet tube 7 communicating with the inner cavity, and the orifice of the air jet tube 7 and the outer flow hole 23 is facing the same direction. The preferred air jet tube 22 includes an outer cylinder 221, Return spring 222 and piston disc 223, one end of the outer cylinder 221 is a blind end and the other end communicates with the water storage pipe 2, the piston disc 223 is slidably sleeved in the outer cylinder 221 and close to the water storage pipe 2, and the piston disc 223 passes through the return spring 222 and the outer cylinder 221 are elastically matched, and one end of the air jet pipe 7 is fixedly connected to the outer wall of the outer cylinder 221 and close to the middle connecting round table 11. In Embodiment 1, the water body in the water storage pipe 2 flows downward due to The principle of gravity will squeeze the piston dis...

Abstract

The invention discloses a jet-propelled anti-blocking and dust-falling device for mining. The jet-propelled anti-blocking and dust-falling device comprises a transverse bearing shaft, a water storage pipe, a water tank and a bearing plate. A transverse bearing shaft is arranged, a middle connecting circular truncated cone is arranged on the transverse bearing shaft, a circle of water storage pipe is arranged on each of the two sides of the middle connecting circular truncated cone, the circle of water storage pipe on one side of the middle connecting circular truncated cone forms a conical body, the large end of the water storage pipe is located outside, and an outward outer circulation hole is formed in the end, away from the middle connecting circular truncated cone, of the water storage pipe. The water tank is arranged below the water storage pipe, the water storage pipe moves by a circle to achieve water filling at the low position of the outer circulation hole and air suction at the high position of the outer circulation hole, and the inner circulation hole plays a role in supplementing air and guiding water to flow back to the water tank. The dust collection and falling functions are realized by utilizing the gravity of the water body, so that the dust collection function is realized.

In order to eliminate the dust, a water spray device is usually installed above the drop position to achieve dust reduction by spraying water. However, this kind of dust reduction The method is to wet the dust, and the wet dust will be mixed into the ore again. Because the ore is water-absorbent, there will be a hidden danger of dust during the subsequent ore transfer, and the existing dust suppression device itself is easy to accumulate a large amount of dust, which will cause Clogging and transmission sticking phenomenon. [0003] Therefore, the present invention provides a jet-type anti-blocking and dust-reducing device for mining. ...
