[0002] Mining refers to the activity of extracting mineral resources from the surface or underground. It is crucial for obtaining important resources such as metals and coal. Underground ventilation and dust removal equipment is indispensable in mining because underground mines are enclosed spaces, and a large amount of dust is generated during the mining process. This dust not only affects miners' health, leading to respiratory diseases, pneumoconiosis, and other occupational diseases, but also reduces visibility in the mine, increasing the risk of safety accidents. Existing underground ventilation and dust removal equipment in mines generally uses filters to filter dust, preventing dust from entering the air pump and damaging it. However, after prolonged use, the filters easily become saturated, causing blockage and affecting the normal operation of the ventilation and dust removal equipment. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides an underground ventilation and dust removal device for mining operations. It solves the problem that existing underground ventilation and dust removal devices for mining operations generally use filters to filter dust, which can prevent dust from entering the air pump and causing damage to the air pump. However, after long-term use, the filters are prone to saturation, causing filter blockage and affecting the normal operation of the ventilation and dust removal device.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a mine ventilation and dust removal device, comprising a box body, a shell fixedly connected to the top of the box body, two vertical plates fixedly connected to the top of the shell, a cylinder rotatably connected between the two vertical plates, an outer shell fixedly connected to the top of the cylinder, a worm gear rotatably connected to the outer shell via a bearing, a worm wheel meshing at the bottom of the worm gear, a rotating shaft fixedly connected to the worm wheel, rotating plates fixedly connected to both ends of the rotating shaft, and a pressure plate fixedly connected to the bottom of the rotating plate;
[0005] A connecting plate is provided at the top of the cylinder, and a frame is fixedly connected to the bottom of the connecting plate. A filter screen is fixedly connected inside the frame. A placement hole is opened on the cylinder corresponding to the position of the frame. An air pump is fixedly connected to the bottom of the inner wall of the box. An air outlet pipe is fixed and connected to one side of the air pump. An air inlet pipe is fixed and connected to the top of the air pump. The top end of the air inlet pipe passes through the box and is fixed to the shell and connected to the bottom of the cylinder.
[0006] As a further embodiment of this utility model: the rotating shaft is rotatably connected to the outer shell via a bearing, and the filter screen is located inside the cylinder.
[0007] As a further embodiment of this utility model: the air outlet pipe is fixedly connected to the box body, and a handle is fixedly connected to one side of the top of the box body.
[0008] As a further embodiment of this utility model: the front of the box is provided with several heat dissipation holes, a sleeve is fixedly connected to the front of one of the upright plates, a screw is threaded to the top of the sleeve, and a rotating column is rotatably connected to one of the upright plates through a bearing.
[0009] As a further embodiment of this utility model: the rotating column is located inside the sleeve, one end of the rotating column is fixedly connected to a crank handle, and the other end of the rotating column is fixedly connected to the cylinder body.
[0010] As a further embodiment of this utility model: a knob is fixedly connected to one end of the worm gear, a handle is fixedly connected to the top of the connecting plate, and self-locking casters are fixedly connected to the four corners of the bottom of the housing.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This mine utilizes an underground ventilation and dust removal system. It consists of a placement hole, filter screen, worm gear, worm rotating plate, connecting plate, and pressure plate. To remove the filter screen, turning the knob rotates the worm gear. Since the worm gear meshes with the worm wheel, its rotation causes the worm wheel, rotating shaft, rotating plate, and pressure plate to rotate as well. This loosens the pressure plate, allowing the filter screen to be removed by holding the handle. To install the filter screen, the frame is placed inside the placement hole, and the knob is turned in the opposite direction, rotating the worm gear and pressure plate. This causes the pressure plate to press and fix the connecting plate, completing the filter screen installation. This device allows for easy and quick filter screen installation and removal simply by turning the knob. Furthermore, removing the filter screen facilitates cleaning, preventing saturation and clogging from prolonged use, thus ensuring the normal operation of the system.
[0013] 2. The mine employs an underground ventilation and dust removal device. This device consists of screws, a crank handle, and a cylinder. When the filter is installed, the air pump is activated to suck up dust. Dust is blocked by the filter, and the gas passes through the cylinder, inlet pipe, and air pump, finally being discharged through the outlet pipe for ventilation. To adjust the cylinder angle, the screws are loosened to release the rotating column from the cylinder. The crank handle can then be turned to rotate the column and cylinder, adjusting the cylinder angle. Once the cylinder angle is adjusted to the appropriate position, the screws are tightened to secure the rotating column and cylinder. This device allows for adjustment of the dust suction angle by adjusting the cylinder angle, facilitating the absorption of dust from different angles. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] like Figure 1-5 As shown, this utility model provides a technical solution: a mine ventilation and dust removal device, including a box body 1, a shell 7 fixedly connected to the top of the box body 1, two vertical plates 5 fixedly connected to the top of the shell 7, a cylinder 6 rotatably connected between the two vertical plates 5, an outer shell 12 fixedly connected to the top of the cylinder 6, a worm gear 13 rotatably connected to the outer shell 12 through a bearing, a rotating shaft 16 rotatably connected to the outer shell 12 through a bearing, and a filter screen 22 located inside the cylinder 6.
[0022] The worm gear 13 is engaged with a worm wheel 15 at its bottom. A rotating shaft 16 is fixedly connected to the worm wheel 15. A rotating plate 17 is fixedly connected to both ends of the rotating shaft 16. A pressure plate 18 is fixedly connected to the bottom of the rotating plate 17. A connecting plate 19 is provided on the top of the cylinder 6. A frame 21 is fixedly connected to the bottom of the connecting plate 19. A filter screen 22 is fixedly connected inside the frame 21. An air outlet pipe 25 is fixedly connected to the box 1. A handle 4 is fixedly connected to one side of the top of the box 1.
[0023] A placement hole 23 is provided on the cylinder 6 at the position corresponding to the frame 21. An air pump 24 is fixedly connected to the bottom of the inner wall of the box 1. An air outlet pipe 25 is fixed and connected to one side of the air pump 24, and an air inlet pipe 26 is fixed and connected to the top of the air pump 24. Several heat dissipation holes 2 are provided on the front of the box 1. Because of the heat dissipation holes 2, the heat generated by the air pump 24 during operation can be discharged, preventing the air pump 24 from being damaged due to excessive temperature and ensuring the normal operation of the air pump 24. A sleeve 8 is fixedly connected to the front of one of the upright plates 5. A screw 9 is threadedly connected to the top of the sleeve 8. Because of the screw 9, the rotating column 10 is fixed to the cylinder 6 by tightening the screw 9, which can effectively improve the stability of the cylinder 6 and ensure the normal operation of the cylinder 6. A rotating column 10 is rotatably connected to one of the upright plates 5 through a bearing.
[0024] The top end of the air intake pipe 26 passes through the box body 1 and is fixed to the shell 7 and connected to the bottom of the cylinder 6. The rotating column 10 is located inside the sleeve 8. One end of the rotating column 10 is fixedly connected to the crank handle 11, and the other end of the rotating column 10 is fixedly connected to the cylinder 6. One end of the worm gear 13 is fixedly connected to the knob 14. The top of the connecting plate 19 is fixedly connected to the handle 20. Because the handle 20 is provided, it provides a gripping point, making it easy for personnel to hold the handle 20 to remove the filter screen 22, thus improving the ease of operation. The four corners of the bottom of the box body 1 are all fixedly connected to the self-locking universal wheels 3. Because the self-locking universal wheels 3 are provided, the self-locking universal wheels 3 can change the sliding friction into rolling friction, thereby effectively reducing friction and facilitating the relocation of the device.
[0025] The working principle of this utility model is as follows:
[0026] When the filter screen 22 needs to be disassembled, turn the knob 14 to drive the worm gear 13 to rotate. Since the worm gear 13 is engaged with the worm wheel 15, when the worm gear 13 rotates, it will drive the worm wheel 15, the rotating shaft 16, the rotating plate 17 and the pressure plate 18 to rotate, so that the pressure plate 18 no longer presses and fixes the connecting plate 19, thus loosening the connecting plate 19. At this time, you can hold the handle 20 to disassemble the filter screen 22. When the filter screen 22 needs to be installed, place the frame 21 inside the placement hole 23, and turn the knob 14 in the opposite direction to drive the worm gear 13 and the pressure plate 18 to rotate, so that the pressure plate 18 presses and fixes the connecting plate 19, thus completing the installation of the filter screen 22.
[0027] When the filter screen 22 is in the installed state, start the air pump 24 to suck up the dust. The dust will be blocked by the filter screen 22, and the gas will pass through the cylinder 6, the air inlet pipe 26 and the air pump 24, and finally be discharged from the air outlet pipe 25 for ventilation. When it is necessary to adjust the angle of the cylinder 6, loosen the screw 9 to release the fixed state between the rotating column 10 and the cylinder 6. At this time, you can turn the handle 11 to drive the rotating column 10 and the cylinder 6 to rotate, thereby adjusting the angle of the cylinder 6. When the angle of the cylinder 6 is adjusted to the appropriate position, tighten the screw 9 to fix the rotating column 10 and the cylinder 6.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
