Description

Technical Field

[0001] This invention relates to the field of dust control mechanisms, and in particular to a dust control device for mining with a cleaning function. Background Technology

[0002] Dust control systems for mining are specialized equipment and technical systems used in mining operations to control and eliminate dust pollution. Their core function is to ensure safe production, improve the working environment, and reduce occupational health risks.

[0003] Existing dust control systems in mining come in many types, each used in various situations during mining operations. Baghouse dust collectors are used to filter dust generated during stone crushing, preventing it from entering the air and affecting worker safety and the working environment. After filtering the dust, the baghouse dust collector then transports it. However, existing baghouse dust collectors use spiral blades for dust transport, which results in low transport efficiency, cumbersome dust handling, and potential delays in dust removal from the collection trough, affecting the dust collector's performance. Therefore, improvements are needed. Summary of the Invention

[0020] like Figures 1-3 As shown, multiple pulse generators 4 are evenly arranged on the top surface of the fixed frame 3. The pulse generators 4 are detachably connected to the fixed frame 3. Dust collection bags 5 corresponding to the pulse generators 4 are installed on the support plate 2. The dust collection bags 5 are detachably connected to the support plate 2. The nozzles of the pulse generators 4 face the opening of the dust collection bags 5.

[0021] The housing 1 is equipped with an air inlet pipe 6 and an air outlet pipe 7. The air inlet pipe 6 is connected to the dust collection space below the support plate 2, and the air outlet pipe 7 is connected to the filter chamber formed by the support plate 2 and the fixed frame 3.

[0022] Two hinged opening and closing plates 10 are installed at the bottom of the box 1, and the outer side of the opening and closing plates 10 is hinged to the bottom of the box 1. The two opening and closing plates 10 close the bottom port of the box 1. The box 1 is provided with an opening and closing mechanism to control the rotation of the opening and closing plates 10.

[0023] An opening and closing shaft 9 is installed on the outer side of the opening and closing plate 10, and the opening and closing shaft 9 is rotatably connected to the opening and closing block 8 installed at the bottom of the box 1.

[0024] like Figure 4 As shown, the opening and closing mechanism includes a drive block 11, a bidirectional lead screw 14, and two sliding blocks 16. A T-shaped sliding groove 15 is provided at the bottom of the drive block 11. The bidirectional lead screw 14 is rotatably installed in the sliding groove 15. One end of the bidirectional lead screw 14 extends through the drive block 11 to the outside and is connected to the output end of the drive motor 13. A drive frame 12 is provided on the drive block 11 outside the drive motor 13.

[0025] Two sliding blocks 16 are slidably installed in the sliding groove 15 and are respectively threaded to the two threaded sections of the bidirectional lead screw 14. The sliding blocks 16 are connected to the corresponding opening and closing plates 10 on the same side through the rotating plate 18.

[0026] One end of the rotating plate 18 is hinged to the sliding block 16 via the first hinge shaft 17, and the other end is hinged to the side of the opening and closing plate 10 near the inner side via the second hinge shaft 19.

[0027] like Figure 1 , Figure 3 and Figure 5 As shown, the box body 1 is equipped with a lifting mechanism that controls the movement of the support plate 2 and the fixed frame 3 along the height direction of the box body 1.

[0028] The side of the housing 1 is provided with a guide groove 25 along the height direction, and a movable frame 27 is fixedly installed on the fixed frame 3. A movable block 26 is slidably installed in the guide groove 25 on the movable frame 27.

[0029] The lifting mechanism includes teeth arranged along the height direction on the side of the movable frame 27 and a lifting gear 24 that meshes with the teeth.

[0030] Working principle: When too much dust is collected in the box 1, the drive motor 13 is started, which drives the bidirectional lead screw 14 fixedly connected to the output end of the drive motor 13 to rotate, causing the sliding block 16 threadedly connected to the bidirectional lead screw 14 to rotate, causing the sliding block 16 to slide in the sliding groove 15, so that the sliding blocks 16 move closer to each other, thereby driving the rotating plate 18 rotatably connected to the first hinge shaft 17 to rotate, causing the opening and closing plate 10 fixedly connected to the second hinge shaft 19 to rotate around the axis of the opening and closing shaft 9, thereby realizing the opening and closing of the box 1 for unloading. When it is necessary to inspect and maintain the dust collection bag 5 and the pulse generator 4, start the lifting motor 22, drive the lifting shaft 23 which is fixedly connected to the output end of the lifting motor 22 to rotate, so that the lifting gear 24 which is fixedly connected to the lifting shaft 23 rotates, drive the moving frame 27 which meshes with the lifting gear 24 to move, so that the moving block 26 which is fixedly connected to the moving frame 27 slides in the guide groove 25, and drives the fixed frame 3 which is fixedly connected to the moving frame 27 to move, so that the fixed frame 3 drives the support plate 2 to move away from the box 1, thereby realizing the inspection and maintenance of the internal components of the box 1.

[0031] This invention facilitates effective removal of dust from the dust collection bag by setting a pulse generator corresponding to the dust collection bag; by setting an opening and closing mechanism, the housing can be opened and closed, allowing the dust collected inside the housing to be unloaded quickly, avoiding excessive dust and clogging of the air inlet pipe; by setting a lifting mechanism, the fixed frame can be raised and lowered, making the maintenance and replacement of the pulse generator and dust collection bag more convenient.
