Description

Technical Field

[0001] This utility model relates to the field of mine ventilation and dust removal technology, and in particular to a dust removal and filtration device for mine ventilation. Background Technology

[0002] Due to the special working environment in mines, which is usually accompanied by a large amount of dust, toxic and harmful gases, and high temperature and humidity, a good ventilation system is particularly important. By introducing fresh air and expelling polluted air, the air quality underground can be improved. Dust removal and filtration equipment further purifies the air and reduces suspended particulate matter. Effective ventilation and dust removal can not only reduce the incidence of occupational diseases such as pneumoconiosis, but also improve production efficiency and safety.

[0003] Most existing air dust removal devices are designed based on the principle of unidirectional airflow, which means that air can only enter from the exhaust port, be filtered and treated, and then flow out from the outlet in one direction. This unidirectional airflow pattern limits the distribution range of purified air, preventing clean air from being effectively blown to the surroundings and affecting the overall coverage of air purification. Since the outlet position is fixed, if it is necessary to change the direction of purified airflow or the coverage area, the entire device must be moved to adjust the position of the outlet, which is very inconvenient. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a dust removal and filtration device for mine ventilation.

[0005] A dust removal and filtration device for mine ventilation includes a base, a cylinder, a duct, a filter element, a fan, protective components, and reinforcing components. The cylinder is connected to the base, and an air inlet is opened on the side wall of the cylinder. The filter element is connected to the inside of the cylinder, and the duct is connected to the cylinder. A fan is installed inside the duct, and the duct is connected to the filter element. Exhaust ports are spaced apart along the circumference on the side wall of the duct. Protective components are connected to both the cylinder and the duct, and reinforcing components are connected to the base.

[0006] As a further preferred option, the protective components include a filter screen, with the filter screen installed inside the exhaust vent.

[0007] As a further preferred option, the protective component includes a protective cover, with the protective cover connected inside the air inlet, and the protective cover having an air intake hole.

[0008] As a further preferred embodiment, the reinforcement assembly includes support plates, with at least three support plates circumferentially spaced along the sidewall of the base.

[0009] As a further preferred option, the reinforcement components include fixing nails, with fixing nails slidably connected to the support plates, and the fixing nails penetrating the support plates.

[0010] As a further preferred embodiment, it also includes a hinged frame and a lighting fixture, with the hinged frame connected at intervals along the circumference of the side wall of the duct, and the lighting fixture being hingedly connected to the hinged frame.

[0011] The beneficial effects are as follows: This utility model is equipped with a duct and an exhaust port. The fan discharges the filtered air in the duct to multiple different directions through different exhaust ports, thereby evenly discharging the filtered air into the working environment, reducing dead zones, and thus improving the air quality of the working environment more quickly and effectively, and improving the air purification effect of this filtration equipment.

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" 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 the present invention based on the specific circumstances.

[0019] A dust removal and filtration device for mine ventilation, such as Figures 1-5As shown, it includes a base 1, a cylinder 2, a duct 3, a filter element 4, a fan 5, protective components, reinforcing components, hinge frames 9, and a lighting lamp 10. The cylinder 2 is fixedly connected to the top of the base 1. Two air inlets 201 are spaced apart circumferentially on the side wall of the cylinder 2. The filter element 4 is fixedly connected inside the cylinder 2. The duct 3 is fixedly connected to the top of the cylinder 2. The fan 5 is installed inside the duct 3. The duct 3 is connected to the filter element 4. At least ten exhaust ports 301 are evenly spaced apart circumferentially on the side wall of the duct 3. Protective components are connected to both the cylinder 2 and the duct 3. Reinforcing components are connected to the base 1. At least five hinge frames 9 are fixedly connected circumferentially on the side wall of the duct 3. The lighting lamp 10 is hinged to the side of the hinge frame 9 away from the duct 3.

[0020] like Figures 1-4 As shown, the protective assembly includes a filter screen 302 and a protective cover 6. The filter screen 302 is installed inside the exhaust port 301, and the protective cover 6 is fixedly connected inside the air inlet 201. The protective cover 6 has an air inlet hole 601.

[0021] like Figure 1 As shown, the reinforcement assembly includes a support plate 7 and fixing nails 8. At least three support plates 7 are evenly spaced along the circumference of the side wall of the base 1. The support plates 7 can increase the support area of ​​the base 1 and improve the stability of the filtration device. The top of each support plate 7 is slidably connected with a fixing nail 8, and the fixing nail 8 penetrates the support plate 7.

[0022] During mine ventilation, this filtration device is moved to the designated location and secured to the ground by hammering in the fixing nails 8. This effectively prevents the device from tipping over due to accidental collisions or uneven ground, thus avoiding potential personal injury and equipment damage, and further improving the stability of the filtration device. After installation, the fan 5 draws air from the mine working environment into the filter element 4 through the air inlet 201. The filter element 4 filters out dust from the air, and the filtered air enters the ventilation duct 3 through the filter element 4. The fan 5 then discharges the filtered air from the ventilation duct 3 in multiple directions through different exhaust ports 301, thus ensuring even ventilation. The filtered air is discharged into the working environment, reducing dead zones and thus improving the air quality of the working environment more quickly and effectively, thereby enhancing the air purification effect of this filtration equipment. When the filtration equipment is extracting air, the protective cover 6 can block large particles of foreign matter from entering the air inlet 201, preventing the filter element 4 from being blocked, reducing the risk of wear on the filter element 4, and reducing the maintenance frequency and cost of this filtration equipment. When exhausting air, the filter screen 302 can remove any remaining small particles, bacteria or other pollutants, performing secondary filtration on the exhaust air and improving the cleanliness of the exhaust air. When the working environment is too dark, the lighting lamp 10 can increase the brightness of the working environment, making it easier for workers to carry out mining operations.

[0023] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
