Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mining operation technology, and specifically relates to a dust removal device for mining. Background Technology
[0002] Mining operations (such as drilling, blasting, loading, and transportation) generate a large amount of dust, which can not only affect workers' health but also cause explosions and other safety accidents. Mining dust removal devices are important equipment used to reduce and control the dust generated in mining operations. Effective dust removal devices are crucial for ensuring mine safety and workers' health.
[0003] Existing dust removal devices for mining operate by installing a base at a suitable dust-suppression location. High-pressure nozzles atomize water into fine particles, which are then blown by a fan. The water mist then travels towards the dust generated during mining operations, causing it to combine with the airborne dust and settle, thus achieving dust removal. However, in actual use, the high-pressure nozzles are typically evenly distributed inside the ventilation duct in a fixed position. This results in a fixed spray angle and spray position. The water mist sprayed from the high-pressure nozzles may not be evenly distributed when blown by the fan, preventing it from quickly and fully contacting the dust generated during mining operations. This means that complete dust suppression takes time, potentially delaying the progress of ore operations. Utility Model Content
[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a dust removal device for mining. When suppressing dust generated during mining operations, the high-pressure nozzle rotates around the lateral center of the ventilation duct, continuously approaching and moving away from the duct. This allows the water mist sprayed from the high-pressure nozzle to quickly and evenly form water mist clusters, facilitating full contact with the dust generated during mining operations.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a dust removal device for mining, including a ventilation duct, an installation base is provided at the front end of the ventilation duct, a rotating ring is rotatably provided on the side of the installation base near the ventilation duct, and evenly distributed sliding cylinders are provided on the rotating ring. Sliding rods are slidably provided inside each sliding cylinder. Electric push rods are provided on the side of the sliding cylinder away from the ventilation duct, and the electric push rods are respectively connected and fixed to adjacent sliding rods. High-pressure nozzles are provided at the ends of the sliding rods near the transverse center of the ventilation duct. A fan is provided on the rear side of the ventilation duct. An annular water pipe is provided on the ventilation duct, and the high-pressure nozzles are all connected to the annular water pipe through telescopic pipes.
[0006] As a further improvement of this utility model, the air duct is rotatably mounted inside the rotating frame via a rotating shaft, the rotating frame is rotatably mounted on the upper surface of the support via a rotating shaft, a motor is mounted on the outer side of the rotating frame, the output shaft of the motor is fixed to the rotating shaft via a coupling, and a second motor is mounted at the top inside the support, the output shaft of the second motor is fixed to the rotating shaft via a coupling.
[0007] As a further improvement of this utility model, an external gear ring is fixedly sleeved on the outer arc surface of the rotating ring, and a gear is rotatably arranged on the lower inner side of the mounting base through a support shaft. The gear meshes with the external gear ring. A motor three is arranged on the mounting base, and the output shaft of motor three is fixed to the support shaft through a coupling. A control box is arranged at the top of the bracket, and the electric push rod, fan, motor one, motor two and motor three are all electrically connected to the control box.
[0008] As a further improvement of this utility model, a base plate is provided on the lower surface of the bracket, and multiple mounting holes are provided on the lower surface of the base plate, and a rubber pad is provided on the lower surface of the base plate.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] Firstly, the ring-shaped water pipe is connected to an external water source, and the operation of the blower is controlled by the control box. The water is atomized by high-pressure nozzles and blown by the blower towards the dust generated during mining.
[0011] Secondly, the control box regulates the operation of the electric push rod and the motor, so that the rotating ring drives the high-pressure nozzle to rotate around the horizontal center of the air duct, constantly approaching and moving away from the horizontal center of the air duct. This allows the water mist sprayed from the high-pressure nozzle to quickly and evenly form water mist clusters, which, when blown by the fan, can quickly and evenly reduce dust.
[0012] Thirdly, the operation of motor one and motor two is controlled by the control box, which causes the air duct to rotate vertically. The direction of dust suppression is controlled by the cooperation of motor one and motor two.
[0013] Fourth, by passing the bolt through the mounting hole to fix the base plate to the ground, the lower surface of the base plate can effectively protect the underside of the base plate. Attached Figure Description

Detailed Implementation
[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0021] like Figure 1 , 3 As shown, the device includes a ventilation duct 105. A mounting base 201 is located at the front end of the ventilation duct 105. A rotating ring is rotatably mounted on the side of the mounting base 201 near the ventilation duct 105. Evenly distributed sliding cylinders 202 are mounted on the rotating ring. Sliding rods 203 are slidably mounted inside each sliding cylinder 202. An electric push rod 207 is mounted on the side of the sliding cylinder 202 away from the ventilation duct 105. The electric push rod 207 is connected and fixed to adjacent sliding rods 203. High-pressure nozzles 204 are mounted on the ends of the sliding rods 203 near the transverse center of the ventilation duct 105. A fan 106 is located on the rear side of the ventilation duct 105. An external gear ring 208 is fixedly fitted onto the outer arc surface of the rotating ring. A gear 209 is rotatably mounted on the lower side of the mounting base 201 via a support shaft. The gear 209 meshes with the external gear ring 208. An annular water pipe 205 is mounted on the ventilation duct 105. The high-pressure nozzles 204 are connected to the annular water pipe 205 via telescopic pipes 206.
[0022] like Figure 2 , 4 As shown, the air duct 105 is rotatably mounted inside the rotating frame 104 via a rotating shaft. The rotating frame 104 is rotatably mounted on the upper surface of the support 101 via a rotating shaft. A motor 107 is mounted on the outer side of the rotating frame 104. The output shaft of the motor 107 is fixed to the rotating shaft via a coupling. A motor 2 108 is mounted at the top inside the support 101. The output shaft of the motor 2 108 is fixed to the rotating shaft via a coupling.
[0023] like Figure 4 As shown, a motor 210 is mounted on the mounting base 201, and the output shaft of the motor 210 is fixed to the support shaft by a coupling.
[0024] like Figure 1 , 2 As shown, a control box 301 is installed at the top of the inside of the bracket 101. The electric push rod 207, fan 106, motor one 107, motor two 108 and motor three 210 are all electrically connected to the control box 301.
[0025] When in use, move the bracket to a suitable position, then connect the annular water pipe 205 to an external water source, and control the operation of the blower 106 through the control box 301. The external water source inputs water into the annular water pipe 205, and then inputs it into the high-pressure nozzle 204 through the telescopic pipe 206. The high-pressure nozzle 204 atomizes and sprays the water out, and the blower 106 blows the water source towards the dust generated during mining.
[0026] The control box 301 controls the operation of motor 107 and motor 108, so that motor 107 controls the rotation between the rotating frame 104 and the support 101, so that the rotating frame 104 drives the air duct 105 to rotate horizontally, and motor 108 controls the rotation between the air duct 105 and the rotating frame 104, so that the air duct 105 rotates vertically. The direction of dust suppression is controlled by the cooperation of motor 107 and motor 108.
[0027] The control box 301 regulates the operation of the electric push rod 207 and the motor 210, causing the extension end of the electric push rod 207 to slide between the connected slide rod 203 and the slide cylinder 202. This causes the high-pressure nozzle 204 to continuously approach and move away from the transverse center of the air duct 105. The output shaft of the motor 210 drives the gear 209 connected to it to rotate. Through the meshing relationship between the gear 209 and the external gear ring 208, the rotating ring containing the external gear ring 208 rotates. As the rotating ring drives the high-pressure nozzle 204 to rotate around the transverse center of the air duct 105, it continuously approaches and moves away from the transverse center of the air duct 105. This allows the water mist sprayed by the high-pressure nozzle 204 to quickly and evenly form water mist clusters. The blower 106 then blows the water mist clusters to quickly and evenly reduce dust.
[0028] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a base plate 102 is provided on the lower surface of the bracket 101. Multiple mounting holes 103 are provided on the lower surface of the base plate 102, and rubber pads are provided on the lower surface of the base plate 102. In use, the base plate 102 is fixed to the ground by passing a bolt through the mounting holes 103, and the lower surface of the base plate 102 effectively protects its underside.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
