Furthermore, it also relates to an environmental protection device including the aforementioned closed-type dust collector for coal conveyor belts. Background Technology

[0002] In existing technologies, conveyor belts, as the main equipment for transporting coal in underground mines, are also one of the main sources of coal dust generation. During the transportation process in mines, due to the significant drop between the coal chute and the conveyor belt, a large amount of coal dust is generated as coal falls from the chute onto the belt. Gases containing coal dust are generated at the chute and diffuse into the surrounding area, easily causing large-scale air pollution and damaging the respiratory systems of on-site workers. In addition, coal dust leads to coal waste, and if it enters electrical components, it can easily cause system malfunctions, affecting safe production in the mine.

[0003] In summary, how to effectively reduce the amount of coal dust generated by the coal feeder in the air during operation and reduce the pollution of the environment by coal dust is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The core of this utility model is to provide a closed-loop coal conveyor belt dust collector, which can effectively reduce the coal dust generated during the operation of the coal feeder and reduce the pollution of the environment by coal dust. Another core aspect of this utility model is to provide an environmental protection device including the above-mentioned closed-loop coal conveyor belt dust collector.

[0027] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of the enclosed coal conveyor belt dust removal device provided by this utility model.

[0028] This specific embodiment provides a closed-loop coal conveyor belt dust removal device, including:

[0029] The escape prevention channel 7 is set along the running direction of the coal conveyor belt 5. The escape prevention channel 7 includes two vertical plates set on both sides of the coal conveyor belt 5 and a horizontal top plate set above the two vertical plates.

[0030] The suction channel 3 has an opening in the horizontal top plate for passing through it, and one end of the suction channel 3 is connected to the opening.

[0031] The dust removal device 8 is connected to the other end of the dust suction channel 3. The dust removal device 8 is used to suck the coal dust in the anti-escape channel 7 into the dust suction channel 3 and filter the coal dust.

[0032] It should be noted that the anti-escape channel 7 may include a transparent sealing plate arranged above the coal conveyor belt 5 along the running direction of the coal conveyor belt 5, and transparent sealing plates arranged side by side on both sides of the outer side of the coal conveyor belt 5. The lower edge of the transparent sealing plates on both sides is lower than the lower edge of the coal conveyor belt 5. The transparent sealing plates arranged on both sides and above the coal conveyor belt 5 form a channel on the outside of the coal conveyor belt 5 to prevent coal dust from escaping. Moreover, the enclosed coal conveyor belt dust removal device of this application refers to preventing coal dust from overflowing as much as possible through the anti-escape channel 7, and collecting the coal dust through the dust suction channel 3 and the dust removal device 8. Furthermore, the anti-escape channel 7 does not obstruct the normal operation of the coal conveyor belt 5 and the coal feeder. Therefore, the anti-escape channel 7 does not seal both ends of the coal conveyor belt 5.

[0033] In practical applications, the shape, structure, size, and material of the anti-escape channel 7, the dust extraction channel 3, and the dust removal device 8 can be determined according to the actual situation and needs.

[0034] When using the enclosed coal conveyor belt dust removal device provided by this utility model, coal dust will be generated when the coal feeder conveys coal to the coal conveyor belt. The anti-escape channel 7 can effectively prevent coal dust from overflowing. At the same time, the operation of the dust removal device 8 can be controlled. The dust removal device 8 can suck the coal dust in the anti-escape channel 7 into the dust suction channel 3 and finally filter the coal dust in the dust removal device 8 to prevent the coal dust from floating in the outside air and effectively reduce the pollution of coal dust to the environment.

[0035] In summary, the enclosed coal conveyor belt dust removal device provided by this utility model can effectively reduce the coal dust that floats in the air during the operation of the coal feeder, thereby reducing the pollution of the environment by coal dust.

[0036] In one embodiment, such as Figure 1 As shown, the horizontal top plate has at least two openings spaced apart, and the dust suction channel 3 is inserted into the opening through the dust suction hood 4. The diameter of the first end of the dust suction hood 4 is smaller than the diameter of the second end. The first end of the dust suction hood 4 is connected to the dust suction channel 3, and the second end of the dust suction hood 4 is inserted into the opening at the top of the anti-escape channel 7, so as to effectively collect the coal dust in the anti-escape channel 7 through the dust suction hood 4, the dust suction channel 3, and the dust removal device 8.

[0037] In one embodiment, both the suction channel 3 and the suction hood 4 are made of polypropylene plastic, which has the advantages of being lightweight, tough, and chemically resistant.

[0038] In one embodiment, the dust removal device 8 includes a dust collector 2 and a fan 1 connected to the end of the dust collection channel 3. The fan 1 and the dust collector 2 are connected. The fan 1 generates suction when it operates, creating a negative pressure in the anti-escape channel 7. Then, the coal dust confined in the anti-escape channel 7 is sucked into the dust collection channel 3. The coal dust is filtered out after passing through the dust collector 2, so that the dust removal device 8 can effectively remove the coal dust in the anti-escape channel 7.

[0039] In one embodiment, both the vertical plate and the horizontal top plate are made of transparent polypropylene plastic sheets, allowing operators to visually observe the interior of the escape channel 7. Furthermore, polypropylene plastic sheets are lightweight, corrosion-resistant, high-temperature resistant, and easy to process. Using polypropylene plastic sheets to construct the escape channel 7 helps improve its effectiveness and service life.

[0040] In one embodiment, both vertical plates are sealed to the horizontal top plate to prevent coal dust, which is confined within the escape channel 7, from overflowing from the joint between the vertical plates and the horizontal top plate.

[0041] In one embodiment, the vertical plate and the horizontal top plate are connected by magnetic attraction or by zipper 6.

[0042] It should be noted that the transparent sealing flexible plate (horizontal top plate) above the coal conveyor belt 5 is a single, continuous transparent sealing flexible plate, which can be horizontally suspended above the two vertical plates via a suspension mechanism. Furthermore, the transparent sealing flexible plates (vertical plates) on both sides of the coal conveyor belt 5 consist of multiple interconnected transparent sealing flexible plates, and these multiple transparent sealing flexible plates can be connected via detachable mechanisms. For example, vertical plates on the same side (e.g., a large vertical plate comprising multiple sequentially connected smaller vertical plates) can be connected by magnets attached to the plate edges (e.g., each vertical plate has a plate edge), or by zippers 6 attached to the plate edges, ensuring a tight seal between the vertical plates on the same side. Alternatively, the horizontal top plate and the vertical plates can also be connected by magnets or zippers 6, but the sealing performance at the connection between the horizontal top plate and the vertical plates must be ensured.

[0043] In one embodiment, a coal dust concentration sensor and a control device are also provided in the escape channel 7. Both the coal dust concentration sensor and the dust removal device 8 are connected to the control device. The coal dust concentration sensor is used to detect the coal dust concentration in the escape channel 7. The control device can make a judgment based on the coal dust concentration signal received from the coal dust concentration sensor. If the coal dust concentration in the escape channel 7 is greater than the preset concentration, the control device can control the dust removal device 8 to operate, so as to draw the coal dust in the escape channel 7 into the dust suction channel 3 and finally filter the coal dust in the dust removal device 8 (dust collector 2), so as to avoid the coal dust from drifting into the outside air, avoid the coal dust concentration in the escape channel 7 from exceeding the standard, and effectively reduce the pollution of coal dust to the environment.
