Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression, in particular to a rapid dust suppression device for mines. Background Art

[0002] Mine dust suppression refers to a series of measures for effectively controlling and reducing dust generated during operations such as mining, transportation, and loading and unloading. The purpose of dust suppression is to reduce environmental pollution by dust, improve the working environment, protect the health of workers, prevent the occurrence of occupational diseases, and also help prevent fire and explosion accidents.

[0003] Mine dust suppression technologies mainly include two categories: source dust suppression and emission control. Source dust suppression technologies intervene at the initial stage of dust generation, such as using methods like foam dust suppression and dry fog dust suppression, to make dust particles aggregate into large particles, increase their self-weight, and thus reduce flying. Emission control technologies, on the other hand, remove the already generated dust through means such as adsorption, pressing, isolation, and collection. The applicable environment of source dust suppression technologies is very limited, and most mining, transportation, and loading and unloading environments cannot use source dust suppression technologies. Moreover, the existing emission control dust suppression technologies have a slow dust suppression speed and are difficult to achieve the purpose of protecting the health of workers. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: The utility model provides a rapid dust suppression device for mines to solve the problem that the existing emission control dust suppression technology has a slow dust suppression speed and is difficult to achieve the purpose of protecting the health of workers.

[0005] The technical solution adopted by the utility model to solve the technical problem is: A rapid dust suppression device for mines, comprising: a dust suppression box; a partition plate, which is arranged inside the dust suppression box and divides the dust suppression box into a dust removal chamber and an air outlet chamber; an air inlet, which is arranged on the dust suppression box and is communicated with the dust removal chamber; an air outlet, which is arranged on the dust suppression box and is communicated with the air outlet chamber; a framework, which is installed on the partition plate and encloses an internal space that is communicated with the air outlet chamber; a fiber bag, which is sleeved on the outer peripheral surface of the framework; and a plurality of cleaning brushes, which are arranged at intervals around the framework inside the dust suppression box.

[0006] The beneficial effects of the present utility model are as follows: The air with dust is discharged into the air inlet by a suction power source such as an axial flow fan, and enters the dust removal chamber through the air inlet. The air with dust passes through the cleaning brush and the fiber bag, and finally enters the air outlet chamber. The cleaning brush and the fiber bag can effectively intercept the dust, so that the air in the air outlet chamber is clean air. During the dust suppression process, the dust will continuously accumulate on the outer peripheral surface of the fiber bag, thus gradually reducing the rate of purifying air of the dust suppression equipment. The cleaning brush sweeps away the dust accumulated on the outer peripheral surface of the fiber bag, thereby ensuring the rate of purifying air of the dust suppression equipment. Moreover, since multiple cleaning brushes are arranged around the skeleton, the large particle impurities carried in the air with dust are blocked by the cleaning brushes, ensuring that the fiber bag will not be scratched by the high-speed large particle impurities, improving its service life, and the multiple cleaning brushes also have a certain dust removal efficiency, which can reduce the dust removal pressure of the fiber bag.

Detailed Embodiments

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0031] In this article, terms such as "upper, lower, inner, outer" are established based on the positional relationship shown in the drawings. Depending on the different drawings, the corresponding positional relationship may also change accordingly. Therefore, it cannot be understood as an absolute limitation of the protection scope; moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0032] Embodiment

[0033] As Figures 1 - 3As shown in the figure, a rapid dust suppression device for mines includes: a dust suppression box 4; a partition 8, which is arranged inside the dust suppression box 4 and divides the dust suppression box 4 into a dust removal chamber 12 and an air outlet chamber 9; an air inlet 1, which is arranged on the dust suppression box 4 and is connected to the dust removal chamber 12; an air outlet 5, which is arranged on the dust suppression box 4 and is connected to the air outlet chamber 9; a framework 18, which is installed on the partition 8 and encloses an internal space that is connected to the air outlet chamber 9; a fiber bag, which is sleeved on the outer peripheral surface of the framework 18; and a plurality of cleaning brushes, which are arranged at intervals around the framework 18 inside the dust suppression box 4.

[0034] Specifically, the air with dust is discharged into the air inlet 1 through a suction power source such as an axial flow fan and enters the dust removal chamber 12 through the air inlet 1. The air with dust passes through the cleaning brushes and the fiber bag and finally enters the air outlet chamber 9. The cleaning brushes and the fiber bag can effectively intercept the dust, so that the air in the air outlet chamber 9 is clean air. During the dust suppression process, dust will continuously accumulate on the outer peripheral surface of the fiber bag, which will gradually reduce the rate of purifying air of the dust suppression device. The dust accumulated on the outer peripheral surface of the fiber bag is swept away by the cleaning brushes, so as to ensure the rate of purifying air of the dust suppression device. Moreover, since a plurality of cleaning brushes are arranged around the framework 18, the large particle impurities carried in the air with dust are blocked by the cleaning brushes, ensuring that the fiber bag will not be scratched by the high-speed large particle impurities, improving its service life, and the plurality of cleaning brushes also have a certain dust removal efficiency, which can reduce the dust removal pressure of the fiber bag.

[0035] Further, the cleaning brush includes: a mounting plate 15, which is installed inside the dust suppression box 4; a rotary power source 19, which is arranged on the mounting plate 15; a cleaning roller 16, which is connected to the rotary power source 19; and bristles 17, which are arranged on the outer peripheral surface of the cleaning roller 16, and at least part of the rotary outer contour generatrix of the bristles 17 contacts the framework 18. The rotary power source 19 drives the cleaning roller 16 to rotate, thereby driving the bristles 17 to rotate and sweeping the dust on the outside of the fiber bag. The bristles 17 are made of flexible material. By arranging the cleaning roller 16 and the bristles 17, the fiber bag can be cleaned evenly from top to bottom. Compared with using pulsed air backwashing, the cleaning of the cleaning roller 16 and the bristles 17 is more uniform, which is beneficial to improving the dust suppression rate. The rotary power source 19 is preferably a motor.

[0036] Further, it also includes: a pressure sensor, which is arranged inside the dust suppression box 4; a processor, which is electrically connected to the pressure sensor and electrically connected to the rotary power source 19. The pressure sensor is used to detect the gas pressure inside the dust suppression box 4. When the pressure is large, the processor drives the rotary power source 19 to start to clean the fiber bag, avoiding excessive gas resistance and causing a large amount of air to stay in the dust suppression box 4.

[0037] Further, it further includes: a dust cover 14, the dust cover 14 is arranged on the mounting plate 15, and the rotary power source 19 is located inside the dust cover 14. The dust swept by the bristles 17 will fall, and the dust cover 14 is used to prevent too much dust from remaining on the rotary power source 19, thereby prolonging its service life.

[0038] Further, it further includes: a support plate 2, the support plate 2 is arranged on the outside of the dust suppression box 4; a high-pressure tank 3, the high-pressure tank 3 is arranged on the support plate 2; a backflush pipeline 11, the backflush pipeline 11 is communicated with the high-pressure tank 3; a high-pressure stop valve 6, one end of the high-pressure stop valve 6 is communicated with the high-pressure tank 3, and the other end of the high-pressure stop valve 6 is communicated with the backflush pipeline 11; a plurality of backflush ports 10, the plurality of backflush ports 10 are arranged at intervals on the backflush pipeline 11, and the backflush ports 10 are communicated with the internal space. When the air pressure sensor detects that the gas pressure inside the dust suppression box 4 rises abnormally, the processor will control the high-pressure stop valve 6 to open, and the dust outside the fiber bag will be flushed down by the gas in the high-pressure pipe to achieve pressure relief. Moreover, the processor will stop the intake air and notify the relevant staff.

[0039] Further, it further includes: a base 7, the dust suppression box 4 is installed on the base 7; a dust collection hopper 13, the dust collection hopper 13 is arranged at the bottom of the dust suppression box 4, and the dust collection hopper 13 is communicated with the dust removal chamber 12. The dust gathers in the dust collection hopper 13 and can be automatically cleaned regularly or manually cleaned regularly. The specific cleaning structure and process are mature existing technologies and will not be elaborated here.

[0040] The above-mentioned technical features can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as the scope described in this specification.
