Description

Technical Field

[0001] This utility model relates to the field of mine gas purification technology, specifically a mine mining safety protection device. Background Technology

[0002] During mining operations, the working environment faces numerous severe challenges, among which air quality is particularly prominent, posing a significant threat to miners' health and safety. As mining depths and scales continue to expand, the amount of harmful gases and dust generated in underground mines increases dramatically. During ore extraction, blasting, and transportation, large amounts of toxic gases such as sulfur dioxide, nitrogen oxides, and carbon monoxide are released. These gases not only have a pungent odor but also cause irreversible damage to the respiratory and cardiovascular systems. Long-term exposure can easily lead to serious occupational diseases such as pneumoconiosis, emphysema, and poisoning in miners. Furthermore, the massive amounts of dust generated by ore crushing, machinery operation, and vehicle movement significantly reduce visibility, interfering with miners' vision and increasing the risk of operational errors. This dust also enters the lungs through respiration, further exacerbating health risks.

[0003] However, existing technologies have the following problems in practical use:

[0004] Existing technologies often rely on single-diameter, non-specially designed extraction pipes in practical use, which cannot accurately cover key dust- and gas-generating areas such as mining faces and ore crushing areas. This results in a large amount of harmful gases and dust escaping to other areas of the mine, endangering workers' health. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To overcome the aforementioned deficiencies of the prior art, this utility model provides a mining safety protection device that solves the problems in the prior art:

[0007] Existing technologies often rely on single-diameter, non-specially designed exhaust pipes in practical use, which cannot accurately cover key dust- and gas-generating areas such as mining faces and ore crushing areas. This results in a large amount of harmful gases and dust escaping to other areas of the mine, endangering the health of workers.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: a mining safety protection device, including a blower, an exhaust chamber fixedly installed on one side of the blower, a purification pipe fixedly installed on the top of the exhaust chamber, an exhaust pipe fixedly installed on the top of the purification pipe, a bracket fixedly installed at the bottom of the exhaust chamber, and an air extraction pipe provided on one side of the exhaust chamber.

[0010] Furthermore, a flange is fixedly installed on one side of the blower, and a stabilizing cross is fixedly installed on one side of the blower.

[0011] Furthermore, a waste bin is fixedly installed on one side of the exhaust chamber, a clamping pipe is fixedly installed on the top of the exhaust chamber, and one side of the exhaust chamber is connected to the flange of the blower.

[0012] Furthermore, a snap-fit ​​plate is fixedly installed at the bottom of the purification pipe, a filter tube is fixedly installed at the bottom of the purification pipe, and the bottom of the purification pipe is connected to the snap-fit ​​tube of the exhaust chamber through the snap-fit ​​plate.

[0016] Furthermore, a protective sleeve is fixedly connected to the outer surface of the suction pipe, and a suction hood is fixedly connected to the bottom of the suction pipe.

[0017] (III) Beneficial Effects

[0018] This utility model provides a safety protection device for mining operations, which has the following beneficial effects:

[0019] This mining safety protection device, through the coordinated arrangement of an exhaust chamber, purification pipe, support frame, and extraction pipe, facilitates the extraction of contaminated air during operation. The exhaust chamber plays a crucial role in transfer and preliminary treatment, working in conjunction with the bottom support frame to form a stable support structure. The support frame can be flexibly adjusted in angle and force according to actual working conditions to adapt to complex mine terrain, ensuring the entire device stands stably underground. Even under vibration from ore transportation, mining blasting, or other disturbances, it will not easily tip over, guaranteeing continuous operation. Furthermore, the exhaust chamber can perform preliminary filtration of contaminated gases, expelling the gases while retaining dust inside, requiring only periodic cleaning. The purification pipe significantly improves air purification efficiency, and its bottom device allows for convenient and quick assembly, facilitating installation, maintenance, and filter replacement. The internal filter can efficiently adsorb dust, heavy metal particles, and harmful gases such as sulfur dioxide and nitrogen oxides, effectively preventing pollutants from being emitted to the outside and protecting the surrounding ecological environment of the mine.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a mining safety protection device, which is mainly used in the scenario of gas avoidance inside the mine.

[0027] Example 1:

[0028] To make it easier to extract waste gas during use, a device blower 1 and an extraction pipe 6 are provided.

[0029] The equipment includes a blower 1, an exhaust chamber 2 with an extraction pipe 6 on one side, a flange 7 fixedly installed on one side of the blower 1, a stabilizing cross 8 fixedly installed on one side of the blower 1, a protective sleeve 18 fixedly connected to the outer surface of the extraction pipe 6, and an extraction hood 19 fixedly connected to the bottom of the extraction pipe 6. Therefore, in actual mining operations, when it is necessary to extract and purify polluted air underground, the operator first turns on the blower 1. Its stabilizing cross 8 structure is firmly supported on the ground or a flat surface, effectively resisting the vibration generated during operation and ensuring stable operation of the equipment. At the same time, the extraction hood 19 at the bottom of the extraction pipe 6 is designed with a trumpet-shaped opening based on aerodynamic principles, covering a large area of ​​polluted air sources such as mining faces and ore crushing areas. The powerful extraction force is transmitted through the extraction pipe 6. Under the protection of the protective sleeve 18, the extraction pipe 6 is not afraid of damage caused by ore collision and friction, and successfully and continuously extracts polluted air to the exhaust chamber 2, providing a sufficient air source for the subsequent purification process and efficiently ensuring the air quality underground.

[0030] Example 2:

[0031] In order to make it easier for the device to discharge gas during use, a device purification pipe 3 and an exhaust pipe 4 are provided;

[0032] An exhaust pipe 4 is fixedly installed at the top of the purification pipe 3, a clamping plate 11 is fixedly installed at the bottom of the purification pipe 3, and a filter pipe 12 is fixedly installed at the bottom of the purification pipe 3. The bottom of the purification pipe 3 is connected to the clamping pipe 10 of the exhaust chamber 2 via the clamping plate 11. A flexible hose 13 is fixedly connected to the top of the exhaust pipe 4, and an exhaust hood 14 is fixedly installed on one side of the flexible hose 13. Therefore, when the gas, after preliminary treatment in the exhaust chamber 2, enters the purification pipe 3, the clamping plate 11 at the bottom of the purification pipe 3 and the clamping pipe 10 of the exhaust chamber 2 fit tightly together to ensure a seamless connection and prevent gas leakage. The internal filter... Pipe 12 uses multi-layer high-efficiency filter materials, such as activated carbon fiber and fine metal mesh, which can accurately adsorb dust, heavy metal particles and various harmful gases such as sulfur dioxide and nitrogen oxides. The purified air flows upward. The flexible hose 13 at the top of the exhaust pipe 4 can flexibly adjust the exhaust direction according to the actual layout and personnel and equipment distribution in the well, so that the exhaust hood 14 can discharge the purified air away from the dense work area. This not only avoids the impact of airflow on personnel and equipment, but also ensures the reasonable distribution of fresh air in the well, effectively maintaining a good working environment.

[0033] Example 3:

[0034] In order to make the device more practical during use, an exhaust chamber 2 and a support 5 are provided.

[0035] A bracket 5 is fixedly installed at the bottom of the exhaust chamber 2, a waste bin 9 is fixedly installed on one side of the exhaust chamber 2, and a clamping pipe 10 is fixedly installed at the top of the exhaust chamber 2. One side of the exhaust chamber 2 is connected to the flange 7 of the blower 1. A support rod 15 is fixedly connected to the bottom of the bracket 5, and a cross support rod 16 is clamped in the middle of the bracket 5. Bolts 17 are fixedly installed at the four corners of the cross support rod 16. The four corners of the cross support rod 16 are threadedly connected to the inner wall of the bracket 5 through the bolts 17. Therefore, under the complex and varied terrain conditions underground, the operator can adjust the position of the cross support rod 16 by loosening or tightening the four corners according to the actual working conditions. Bolt 17 allows for flexible adjustment of the support angle and force of bracket 5, ensuring that exhaust chamber 2 and the entire device stand firmly. Waste bin 9 on one side of exhaust chamber 2 facilitates the collection of dust, slag, and other solid waste trapped during the purification process. Regular cleaning of waste bin 9 can easily handle these pollutants, preventing them from accumulating underground and causing secondary pollution, clogging the drainage system, or affecting transportation channels. At the same time, exhaust chamber 2 is tightly connected to blower 1 through flange 7, ensuring smooth gas transmission and providing stable and reliable air purification and circulation for mining operations, comprehensively improving the safety and efficiency of mining operations.

[0036] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0037] In this invention, the working steps of the device are as follows:

[0038] First, before activating the safety protection device, conduct a comprehensive inspection of all components again. Check for any loose bolts at the connection points, especially the connections between blower 1 and exhaust chamber 2, and between purification pipe 3 and exhaust chamber 2. Check for bends or blockages in the extraction pipe 6 and exhaust pipe 4. Ensure that the extraction hood 19 and exhaust hood 14 are in their optimal working positions. Confirm that the filter pipe 12 is clean; if necessary, replace or clean it in advance. At the same time, check that the waste bin 9 is empty and ready to receive new solid waste. After all checks are completed, the operator turns on the power switch of blower 1 and starts blower 1. Observe the operating status of blower 1, including whether the motor speed is normal, whether there is any abnormal vibration or noise, and whether the stabilizing cross 8 effectively stabilizes the equipment. At the same time, pay attention to whether there is any gas leakage in components such as exhaust chamber 2 and purification pipe 3. If there is any leakage, stop the machine immediately, investigate the cause, and repair it. As blower 1 runs, polluted air should be continuously drawn into exhaust chamber 2 through extraction pipe 6, filtered and purified in purification pipe 3, and then discharged through exhaust pipe 4.
