Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ore chute dust prevention, and more particularly to an ore chute dust prevention device. BACKGROUND

[0002] With the increasing depth of underground mining, the ore chute has the advantages of large transportation capacity, high transfer efficiency, convenient operation and management, simplicity and reliability, and plays an important role in the process of underground mining. Since the ore chute is relatively high, when the ore is transported in the ore chute by its own weight, a large impact will be generated, which will compress the air in the ore chute and generate a large impact airflow. Since the ore chute and the ore both have a lot of dust, the impact airflow carries dust when flowing out of each ore chute, thereby forming a large air pollution and affecting the health of the workers. At present, the methods of spraying dust or negative pressure air exhaust are mostly used for dust removal in the ore chute. However, the dust concentration generated in the ore chute is high, and most of the dust is respirable dust with a particle size as low as 5 μm, and the impact airflow speed is relatively fast. This dust is not ideal for treatment by the above methods, and the use of excessive water resources and the investment of negative pressure air exhaust devices will also increase the cost of dust treatment.

[0003] According to the metal mine ore chute dust removal device disclosed in Chinese Patent No. CN112983531A, a telescopic flow guide, a dust suction fan and a dust removal pool are included. The flow guide is telescopically embedded in the side wall of the ore chute. The flow guide is a cavity structure with an air inlet at the bottom and a dust suction fan installed at the left end.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0028] Refer to the drawings in the description Figures 1-5As shown, the ore pass dust prevention device of the embodiment of the present application comprises a main ore pass roadway 1, a feeding roadway 2 is connected to the top of the main ore pass roadway 1, the size of the feeding roadway 2 is smaller than that of the main ore pass roadway 1, and the feeding roadway 2 is used to transport ore into the main ore pass roadway 1, each branch roadway of the main ore pass roadway 1 is provided with a feeding roadway 2, a dust suction pipeline 27 is connected to one side of the main ore pass roadway 1, a purification and dust removal assembly 28 is arranged in the dust suction pipeline 27, the purification and dust removal assembly 28 is a device with negative pressure dust suction and dust removal in the prior art, and the purification and dust removal assembly 28 is not described in detail in this application, and only one set of dust suction pipeline 27 and purification and dust removal assembly 28 is arranged, a dust falling assembly is arranged on the inner side of the feeding roadway 2, a dust isolation assembly is arranged on the inner side of the main ore pass roadway 1, a recovery assembly is arranged in the dust isolation assembly, a guide assembly is arranged at the bottom of the dust isolation assembly, the guide assembly is arranged in a form of close contact with the inner wall of the main ore pass roadway 1, and the dust falling assembly is connected with the dust isolation assembly.

[0029] The dust isolation assembly comprises a first connecting piece 11 fixedly connected to one side of the roadway door 3, a transmission connecting rod 12 rotatably sleeved on the outer side of the first connecting piece 11, a dust isolation baffle 13 hinged to the top end of the main ore pass roadway 1, a second connecting piece 14 fixedly connected to the top of the dust isolation baffle 13, and the transmission connecting rod 12 is sleeved on one side of the second connecting piece 14.

[0030] It should be noted that when the roadway door 3 is opened to transport ore into the main ore pass roadway 1, the roadway door 3 is turned downward, the transmission connecting rod 12 is driven to descend by the first connecting piece 11, and then the dust isolation baffle 13 is turned downward, ore can be poured into the feeding roadway 2 after the roadway door 3 and the dust isolation baffle 13 are completely opened, the roadway door 3 is closed in time after pouring is completed, and the bottom end port of the feeding roadway 2 can be closed by the dust isolation baffle 13 after the roadway door 3 and the dust isolation baffle 13 are closed, so that dust is prevented from rising into the feeding roadway 2 along with the airflow. It should be noted that the roadway door 3 needs to be closed in time after the ore is poured completely, so as to prevent dust from overflowing upward when the dust isolation baffle 13 is not closed, and the ore cannot be continuously poured, but a single load of ore can be poured by using a shovel truck, so that the dust can be effectively reduced from overflowing from the main ore pass roadway 1 when the ore is not completely formed into a shock airflow, and the ore can be transported through only one roadway at the same time when the main ore pass roadway 1 has multiple branch roadways, so as to prevent dust from overflowing from the remaining roadways when multiple roadways are opened.

[0031] When the dustproof baffle 13 is used to block the impact airflow and dust generated by the ore falling, the purification and dust removal assembly 28 is opened at the same time to attract the impact airflow and dust. Since the impact airflow blocked by the dustproof baffle 13 cannot enter the feeding tunnel 2, it flows into the dust suction pipeline 27, and then the impact airflow and dust are guided into the dust suction pipeline 27. After the impact airflow disappears, the purification and dust removal assembly 28 attracts and processes the disordered dust, thereby achieving the purpose of effectively treating the dust in the main ore chute tunnel 1. Only one negative pressure dust suction and removal device is needed for one ore chute to achieve dust treatment, which improves the dust treatment efficiency and effectively reduces the cost of dust treatment.

[0032] Further, as shown in Figure 6 and Figure 8 , the guide assembly includes a limiting plastic frame 23 fixedly connected to the bottom of the dustproof baffle 13. The outer side of the limiting plastic frame 23 is rotatably connected with an arc-shaped plastic frame 24. The arc-shaped plastic frame 24 has a certain elasticity. Two elastic sheets 25 are symmetrically arranged at corresponding positions on both sides of the arc-shaped plastic frame 24. The elastic sheets 25 are of elastic structure. The bottom of the limiting plastic frame 23 is fixedly connected with an elastic cloth 26. The elastic cloth 26 has elasticity. The elastic cloth 26 is sleeved on the outer side of the arc-shaped plastic frame 24. The elastic cloth 26 abuts against the inner wall of the main ore chute tunnel 1.

[0033] It should be noted that, in the dust baffle 13 is turned down to make the main ore pass 1 top end port in the open state, the limit plastic frame 23 and the arc plastic frame 24 will be synchronized with the dust baffle 13 to turn over, the limit plastic frame 23 will rotate on the inside of the arc plastic frame 24, when the arc plastic frame 24 contacts with the inner wall of the main ore pass 1, the arc plastic frame 24 and the spring 25 will correspondingly deform, so that the arc plastic frame 24 and the spring 25 gradually tend to be vertical, and at this time the limit plastic frame 23 and the arc plastic frame 24 coincide, so that when the dust baffle 13 is opened, the guide assembly can be synchronized to avoid affecting the conveying of the ore, and when the ore is poured, the dust baffle 13 is in a horizontal closed state, the arc plastic frame 24 naturally droops at one end under its own weight, and the arc plastic frame 24 and the spring 25 restore to an arc shape under the elastic force of itself, so that one side of the elastic cloth 26 is arc-shaped with the plasticity of the arc plastic frame 24, and the side of the elastic cloth 26 contacts with the inner wall of the main ore pass 1, so as to further block the dust, and the side of the elastic cloth 26 is arc-shaped, which can naturally guide the impact airflow generated by the ore descending, so that the airflow and the dust carried by the airflow flow naturally into the dust suction pipeline 27, thereby avoiding the airflow and the dust directly impacting on the bottom of the dust baffle 13, and the elastic cloth 26 contacts with the airflow and the dust, which can avoid the dust adhering to the bottom of the dust baffle 13, and when the dust baffle 13 is turned down to make the guide assembly be stored, the shape of the elastic cloth 26 will change, so as to shake off the dust adhered to the surface of the elastic cloth 26, avoiding the phenomenon of excessive dust accumulation on the surface of the elastic cloth 26.

[0034] Further, as shown in Figure 1 、 Figure 2 and Figure 7 , the dust falling assembly includes an ore pass door 3 hinged at the top end of the feeding pass 2, the ore pass door 3 is provided with two doors to increase the opening and closing speed, the bottom of the ore pass door 3 is fixedly connected with a plurality of mist nozzles 4, the plurality of mist nozzles 4 are connected in series with each other, the top of the ore pass door 3 is fixedly connected with a first water delivery pipe 5, the first water delivery pipe 5 is connected with a water pump to deliver water to the plurality of mist nozzles 4 through the first water delivery pipe 5, the first water delivery pipe 5 is in communication with the mist nozzles 4, an arc-shaped chute 6 is formed on one side of the feeding pass 2, a limit pulley 7 is slidably connected to the inside of the arc-shaped chute 6, the limit pulley 7 is fixedly connected to one side of the ore pass door 3, a double-groove transmission frame 8 is slidably connected to one side of the feeding pass 2, the limit pulley 7 is slidably connected to the inside of the double-groove transmission frame 8, a connecting protruding column 9 is fixedly connected to one side of the double-groove transmission frame 8, a hydraulic cylinder 10 is fixedly connected to one side of the feeding pass 2, and the connecting protruding column 9 is inserted into the output end of the hydraulic cylinder 10.

[0035] It needs explanation that, by starting the hydraulic cylinder 10 to drive the connecting convex column 9 to descend, and then make the double-groove transmission frame 8 descend, through the descent of the double-groove transmission frame 8 to promote the limiting pulley 7 to slide on the inside of the arc-shaped sliding groove 6, the limiting pulley 7 simultaneously slides on the inside of the double-groove transmission frame 8, so that the two sides of the roadway door 3 can be gradually opened by turning down, and vice versa, the roadway door 3 can be closed, when the dust is treated, by closing the roadway door 3, opening the water pump connected with the first water pipe 5, and sending water to the plurality of mist nozzles 4 through the first water pipe 5, and forming water mist through the plurality of mist nozzles 4, spraying the space inside the feeding roadway 2, so as to avoid part of the dust in the main shaft roadway 1 from escaping into the feeding roadway 2, thereby further preventing dust from escaping from the feeding roadway 2 into the mine tunnel when the roadway door 3 is opened.

[0036] Further, as shown in Figure 3 and Figure 6 , the recovery assembly includes a water inlet hole 15 opened at the top of the dust-proof baffle 13, a water guide chamber 16 is opened in the inside of the dust-proof baffle 13, the inner contour of the water guide chamber 16 is arranged in a rectangular shape, a second water pipe 29 is fixedly connected to one side of the dust-proof baffle 13, the second water pipe 29 is connected with a sewage bucket or a sewage treatment device, the second water pipe 29 is arranged in a communication manner with the water guide chamber 16, the water inlet hole 15 is arranged in a communication manner with the water guide chamber 16, a hole sealing baffle 17 is slidingly connected to the top of the dust-proof baffle 13, the size of the hole sealing baffle 17 is larger than the size of the water inlet hole 15, an arc-shaped strip plate 18 is fixedly connected to one end of the hole sealing baffle 17, the arc-shaped strip plate 18 is arranged in a resisting manner with the main shaft roadway 1, a sealing plug strip 19 is fixedly connected to one side of the arc-shaped strip plate 18, the sealing plug strip 19 is inserted into the inside of the dust-proof baffle 13, the sealing plug strip 19 is made of rubber material and can close one side of the dust-proof baffle 13 after being inserted into the dust-proof baffle 13, a sliding rod 20 is fixedly connected to one side of the sealing plug strip 19, the sliding rod 20 is slidingly connected to the inside of the dust-proof baffle 13, a spring 21 is fixedly connected to one end of the sliding rod 20, the spring 21 is in a compressed state when the sealing plug strip 19 is inserted into the inside of the dust-proof baffle 13, a fixed block 22 is fixedly connected to one end of the spring 21, and the fixed block 22 is fixedly connected to the inside of the dust-proof baffle 13.

[0037] It should be noted that, in the mist nozzle 4 sprays water mist to the inside of the feed lane 2 space for dust suppression, water mist mixed dust falls on the top of the dust baffle 13, and enters the inside of the water guide chamber 16 through the plurality of water inlet holes 15, thereby storing the dust sewage through the water guide chamber 16, when the dust sewage level in the water guide chamber 16 rises to coincide with the second water pipe 29, the dust sewage flows into the second water pipe 29, thereby recycling the dust sewage, by using the sewage treatment device, the dust sewage can be treated and reused, thereby reducing the excessive investment and waste of water resources; at the same time, when the dust baffle 13 is turned down, the arc-shaped strip plate 18 gradually loses contact with the inner wall of the main chute lane 1, at this time the arc-shaped strip plate 18 loses the limit of the main chute lane 1, the spring 21 is stretched to push the sliding rod 20 to drive the sealing plug strip 19 to slide out of the inside of the dust baffle 13, because most of the sewage in the water guide chamber 16 flows out through the second water pipe 29, part of the residual sewage mixed with more settled dust, thereby causing the flowability of the part of the residual sewage to be poor, unable to flow into the second water pipe 29, through the inclined state of the dust baffle 13 when it is turned down, thereby pouring the residual sewage in the water guide chamber 16 out of the water guide chamber 16, and the flow of sewage can make the dust flow out of the water guide chamber 16, the sewage falls from the main chute lane 1 to the bottom of the main chute lane 1, thereby completely treating the sewage in the water guide chamber 16 to avoid the accumulation of dust inside the water guide chamber 16.

[0038] At the same time, when the sealing plug strip 19 slides out of the inside of the dust baffle 13, the arc-shaped strip plate 18 drives the hole sealing baffle 17 to slide synchronously, thereby closing and shielding the water inlet hole 15 through the hole sealing baffle 17, thereby avoiding the impact between the ore and the dust baffle 13 when the dust baffle 13 is turned down to transport the ore, causing the broken ore to enter the inside of the water guide chamber 16 through the water inlet hole 15; when the dust baffle 13 is reset, the arc-shaped strip plate 18 gradually contacts the inner wall of the main chute lane 1, and during the upward turning process of the dust baffle 13, the arc-shaped strip plate 18 gradually slides to the direction of the dust baffle 13 under the limit of the inner wall of the main chute lane 1, causing the sealing plug strip 19 to gradually insert into the dust baffle 13, and the spring 21 contracts, the hole sealing baffle 17 gradually slides to one side, and the water inlet hole 15 is exposed, thereby enabling the dust to be recycled.
