Description

Technical Field

[0001] This utility model relates to the field of mining engineering technology, and in particular to a windbreak device for a ventilation door wall with a belt. Background Technology

[0002] The belt conveyor wall-penetrating windbreak device is a specialized piece of equipment designed to address air leakage problems that occur when belt conveyors pass through ventilation door walls during mine production. Due to belt-driven operations and the irregular shapes of transported materials, traditional methods of installing windbreak curtains at belt openings, such as using ventilation duct cloth or belt conveyor skin, suffer from drawbacks such as improper installation, short lifespan, and poor wind-blocking effect. The belt conveyor wall-penetrating windbreak device, while ensuring the normal operation of the belt conveyor, significantly improves the airflow isolation effect, reduces air leakage, and lowers dust levels, thereby ensuring the stability and safety of the mine ventilation system and improving the quality of the underground working environment.

[0003] Currently, most ventilation doors typically have belt conveyor holes on one side of the wall for slag removal. When the belt conveyor is transporting coal slag, the ventilation door is located at the only connection point between two ventilation shafts, resulting in high air pressure and severe air leakage through the belt conveyor holes. Furthermore, the belt conveyor operation causes dust to fly around, affecting the stability and safety of the Yuxin ventilation shaft system and requiring frequent maintenance. Additionally, the friction between the belt conveyor and the belt holes during operation accelerates the wear and tear of the belt itself.

[0004] Therefore, it is necessary to provide a new type of windbreak device for damper walls with belts to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a windproof device for a damper wall with a belt.

[0006] The windbreak device for a wall-mounted damper with a belt includes: a frame; a rotating rod fixedly connected to the top front side of the frame; an upper windbreak plate rotatably connected to the outside of the rotating rod; a semi-circular protrusion at the bottom of the upper windbreak plate; a rotation angle of 0~90°; a lower windbreak plate fixedly connected to the inner front side of the frame below the upper windbreak plate; a semi-circular groove on the inner top of the lower windbreak plate; a belt moving hole between the upper and lower windbreak plates; multiple auxiliary wheels at the groove at the top of the lower windbreak plate; multiple windbreak curtains fixedly connected to the top interior of the frame; symmetrically fixedly connected receiving blocks at the bottom front side of the frame; movable holes on the inner walls of the receiving blocks; sliding blocks slidably connected to the inner walls of the movable holes; lower adjusting rollers rotatably connected to the adjacent sides of the two sliding blocks; and an elastic component installed on the inner wall of the movable holes.

[0008] Preferably, the outer side of the upper baffle plate contacts the top of the front inner wall of the frame, and the upper conveying roller is installed inside the frame behind the lower baffle plate.

[0009] Preferably, the bottom protrusion of the upper wind deflector is consistent with the top protrusion of the lower wind deflector, so that when the upper and lower wind deflectors are closed, only the belt moving hole is left to allow the belt to move.

[0010] Preferably, the auxiliary wheel is made of wear-resistant rubber with anti-slip texture on the surface, which can effectively reduce wear on the belt and increase friction between the belt and the belt.

[0011] Preferably, the inner wall of the sliding block and the outer wall of the fixed rod are slidably connected.

[0012] Preferably, the top end of the compression spring is fixedly connected to the top end of the inner wall of the movable hole, and the bottom end of the compression spring is fixedly connected to the top end of the sliding block.

[0013] Compared with related technologies, the windbreak device for the damper wall with belt provided by this utility model has the following advantages: Excellent air leakage control: This utility model, through the cooperation of the upper and lower wind deflectors and the assistance of the wind deflector curtain, can reduce air leakage in all directions, with a partition area of ​​over 95%. It effectively solves the serious air leakage problem caused by the air door being located at the only connection point between two air shafts and the high wind pressure, ensuring the stability of the ventilation system, reducing the airflow carrying dust, significantly reducing dust flying during belt operation, and improving the safety of the ventilation system.

[0014] Belt protection is in place: This utility model uses wear-resistant rubber with anti-slip texture on the auxiliary wheel at the lower baffle to reduce belt wear. The lower adjusting roller, together with the elastic component, can adapt to changes in belt tension, preventing excessive friction between the belt and the device, avoiding accelerated wear and tear of the belt body, and extending the belt's service life.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] Please see Figures 1 to 5 A windbreak device for a damper wall with a belt includes a frame 1. A rotating rod 2 is fixedly connected to the inside of the front top of the frame 1. An upper windbreak plate 3 is rotatably connected to the outside of the rotating rod 2. The outside of the upper windbreak plate 3 contacts the top of the front inner wall of the frame 1, ensuring that there is no gap between the upper windbreak plate 3 and the frame 1 when the frame is closed, effectively blocking the airflow. A semi-circular protrusion is provided at the bottom of the upper windbreak plate 3, with a rotation angle of 0~90°. A lower windbreak plate 4 is fixedly connected to the front inner wall of the frame 1 below the upper windbreak plate 3. A semi-circular groove is provided on the inner wall of the top of the plate 4. A belt moving hole 5 is provided between the upper wind deflector 3 and the lower wind deflector 4. The bottom protrusion of the upper wind deflector 3 is consistent with the top protrusion of the lower wind deflector 4, so that when the upper wind deflector 3 and the lower wind deflector 4 are closed, only the belt moving hole 5 is left to allow the belt to move, reducing air leakage. Multiple auxiliary wheels 6 are provided at the top groove of the lower wind deflector 4. The auxiliary wheels 6 are made of wear-resistant rubber and have anti-slip texture on the surface, which can effectively reduce the wear on the belt and increase the friction between the belt and the belt. The windbreak curtain 7 is fixedly connected to the top of the inner part of the frame 1. The windbreak curtain 7 is made of flexible fireproof material and its length can cover the upper part of the belt moving hole 5. While blocking the airflow, it can adapt to the up and down jumping of the belt and has fireproof performance, which improves the safety of the device in the underground environment. The upper conveyor roller 8 is installed inside the frame 1 behind the lower windbreak plate 4. The front bottom of the frame 1 is symmetrically fixedly connected to the receiving block 9. The inner wall of the receiving block 9 is provided with a movable hole 12. The inner wall of the movable hole 12 is slidably connected to the sliding block 10. The lower adjusting roller 11 is rotatably connected to the adjacent side of the two sliding blocks 10. The elastic component is installed on the inner wall of the movable hole 12. The elastic component includes a fixed rod 13. The inner wall of the sliding block 10 is slidably connected to the outside of the fixed rod 13, ensuring that the sliding block 10 can slide smoothly up and down along the fixed rod 13 in the movable hole 12, thereby realizing the flexible adjustment of the position of the lower adjusting roller 11. The end of the fixed rod 13 is fixedly connected to both ends of the inner wall of the movable hole 12. A compression spring 14 is sleeved on the outside of the fixed rod 13. The top end of the compression spring 14 is fixedly connected to the top end of the inner wall of the movable hole 12, and the bottom end of the compression spring 14 is fixedly connected to the top end of the sliding block 10. Through the elastic force of the compression spring 14, the lower adjusting roller 11 can adapt to the tension change of the belt and always maintain effective support and adjustment of the belt.

[0020] The working principle of the windbreak device with belt through the wall of the damper provided by this utility model is as follows: When the belt conveyor windbreak device is used for belt conveyor operation, the belt first starts to run. The coal slag on the belt will push the upper windbreak plate 3. Since the upper windbreak plate 3 is installed on the rotating shaft of the rotating rod 2, the rotating rod 2 will drive the upper windbreak plate 3 to rotate under the pushing action of the coal slag. This causes the upper windbreak plate 3 to gradually lift from the initial closed state inside the front top of the frame 1. Since the rotation angle of the upper windbreak plate 3 varies in the range of 0~90°, it makes room for the belt and coal slag to pass through. In addition, it works with the multiple windbreak curtains 7 fixedly connected to the top of the inside of the frame 1 to block the airflow above and further enhance the windbreak effect. Next, the belt continues to rotate and enters the belt moving hole 5 set between the upper baffle plate 3 and the lower baffle plate 4. Multiple auxiliary wheels 6 are set in the groove at the top of the lower baffle plate 4. These auxiliary wheels 6 will rotate as the belt moves. The auxiliary wheels 6 are made of wear-resistant rubber and have anti-slip texture on the surface, which can effectively reduce the wear on the belt and increase the friction between the belt and the belt, assisting the belt to pass smoothly through the belt moving hole 5. At the same time, the upper conveyor roller 8 inside the frame 1, located behind the lower baffle plate 4, will also rotate as the belt rotates, further assisting the belt to run smoothly in the upper part. Then, at the lower part of the belt, the receiving block 9, which is symmetrically fixedly connected to the bottom front side of the frame 1, plays a role. An elastic component is installed in the movable hole 12 on the inner wall of the receiving block 9. A compression spring 14 is sleeved on the outside of the fixed rod 13 in the elastic component. The inner wall of the sliding block 10 is slidably connected to the outside of the fixed rod 13, and the top end of the compression spring 14 is fixedly connected to the top end of the inner wall of the movable hole 12, and the bottom end is fixedly connected to the top end of the sliding block 10. When the belt passes through the lower adjusting roller 11, the change in belt tension will cause the lower adjusting roller 11 to drive the sliding block 10 to slide on the fixed rod 13. The compression spring 14 extends and retracts according to the tension of the belt, thereby adaptively adjusting the position of the lower adjusting roller 11, always maintaining effective support and adjustment for the belt, preventing excessive friction between the belt and other parts of the device. When the pushing force of the coal slag on the belt disappears, the upper baffle 3 automatically falls down under its own weight through the rotation of the rotating rod 2. The semi-circular protrusion at its bottom matches the semi-circular groove at the top of the lower baffle 4, so that when the upper baffle 3 and the lower baffle 4 are closed, only the belt moving hole 5 is left for the belt to move, effectively blocking the airflow and reducing air leakage.

[0021] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
