Description

Technical Field

[0001] The present invention relates to the technical field of mine air pollutants, in particular to equipment for treating air pollutants emitted from total return air in mines. Background Art

[0002] Mine air pollutants primarily include harmful gases and suspended pollutants. Harmful gases include methane (gas), carbon monoxide, hydrogen sulfide, nitrogen dioxide, sulfur dioxide, and carbon dioxide. These gases pose a serious threat to the health and safety of miners. For example, methane is flammable and explosive, carbon monoxide is highly toxic, hydrogen sulfide is highly irritating, nitrogen dioxide and sulfur dioxide can cause pulmonary edema, and carbon dioxide poses a risk of asphyxiation. Suspended pollutants primarily include crystalline silica dust, sulfide dust, respirable coal dust, and potassium nitrate dust. Crystalline silica dust is produced by rock crushing and can easily cause silicosis. Respirable coal dust is the primary pollutant in coal mining. Sulfide dust is associated with specific ores but is not the most common. Potassium nitrate dust is extremely rare in mines.

[0003] A Chinese invention patent, publication number CN111821783A, discloses a computer vision-based blind spot traffic warning device. The device comprises a fixed base, a fixed cavity formed on the fixed base, a purifying core rotatably mounted within the cavity, an air outlet formed on the top inner wall of the cavity, a first connecting piece fixedly mounted within the air outlet, two rotating holes formed on the top of the first connecting piece, round rods rotatably mounted within each rotating hole, fan blades fixedly mounted at the top of each round rod, a second gear fixedly mounted at the bottom of each round rod, and sprockets fixedly mounted on each round rod. The present invention has a reasonable structure and is easy to operate. The purification device is rich in functions, has high purification efficiency and air collection efficiency when used indoors, and has good purification effects.

[0004] In addition, since dust particles in the total return air of mines can easily clog traditional filtering devices, the dust removal efficiency is reduced, and manual cleaning is frequent and costly, which cannot meet the needs of continuous underground operations. At the same time, the adsorption efficiency of adsorption materials such as activated carbon on harmful gases in mines is significantly affected by airflow velocity and pressure. Traditional static adsorption methods are difficult to achieve efficient purification under low concentration and large flow conditions, and have high energy consumption. Traditional pollutant treatment equipment has a low degree of automation and requires manual intervention to regulate the operation of each component. The complex structure makes maintenance difficult, especially in the humid and dusty environment underground. Equipment failure is prone to occur, affecting system stability. Therefore, a computer vision-based road blind spot traffic warning device disclosed in Chinese invention patent CN111821783A cannot efficiently remove dust or improve the absorption effect of harmful gases.

[0044] It should be noted that both the upper and lower ends of the driving rod 304 can be telescopic.

[0045] The following is the working process and principle of the above embodiment:

[0046] The working steps are as follows:

[0047] The operator transports the air to the interior of the processing cylinder 102 through the air supply pipe 201, and then controls the telescopic rod 2033 to start working through the external control device, so that the telescopic rod 2033 drives the piston plate 2034 to slide upward inside the guide trough plate 2031, so that the piston plate 2034 no longer blocks the bottom end of the guide trough plate 2031, so that the mine air inside the processing cylinder 102 enters the interior of the guide trough plate 2031, and the mine air enters the interior of the gauze 3035 through the guide trough plate 2031. When a sufficient amount of mine air is transported to the interior of the gauze 3035, the operator controls the piston plate 2034 to block the bottom end of the guide trough plate 2031 again through the external control device, and then the dust particles inside the mine air are separated from the air under the filtering action of the gauze 3035. Since the mine air contains a certain amount of moisture, it is easy for the dust particles to adhere to the inner wall of the gauze 3035.

[0048] When the dust particles attached to the inner wall of the gauze 3035 affect the filtering effect of the gauze 3035, the operator controls the fixed rod 3032 to start rotating inside the chute 3031 through the external control device, so that the fixed rod 3032 drives the rubber rod 3033 and the rubber plate 3034 to rotate synchronously, so that the gauze 3035 drives the dust particles to rotate synchronously and dehydrates the dust particles through centrifugal force. Then the operator controls the driving rod 304 through the external control device to start working, so that the driving rod 304 drives the support rod 3062 to the side close to the fixed rod 3032. The second support rod 3062 drives the annular rod 3036 to move synchronously, and the annular rod 3036 drives the end of the rubber plate 3034 to move toward the side close to the second fixed rod 3032. Under the action of the annular rod 3036, the rubber plate 3034 drives the gauze 3035 to unfold, and the rubber plate 3034 drives the rubber rod 3033 to slide synchronously on the outer wall of the second fixed rod 3032 away from the driving rod 304. At the same time, the second support rod 3062 drives the fixed block 1 3063 fixed thereto to move synchronously toward the side close to the second fixed rod 30 3064, which is connected to the fixed block 3066, and the sliding block 3065 are moved to the side close to the fixed rod 3032. The side away from the driving rod 304 slides, so that the rubber plate 3034 drives the gauze 3035 to expand and close stably, and then by continuously expanding and closing the gauze 3035, the dust particles attached to the inner wall of the gauze 3035 fall off to the bottom of the guide trough plate 2031. Then the operator controls the rubber rod 3033 through the external control device to drive the rubber plate 3034 to no longer block the guide trough plate 2031, so that the dust particles at the bottom of the guide trough plate 2031 fall off to the inside of the processing cylinder 102 through the gap between the piston plate 2034 and the guide trough plate 2031.

[0049] The funnel-shaped guide trough plate 2031 and the frustum-shaped structure of the gauze 3035 can effectively intercept dust particles in the mine air, and the cleaning mechanism 300 can drive the rubber plate 3034 and the gauze 3035 to expand and close periodically through the driving rod 304, and use centrifugal force and mechanical extrusion to make the dust fall off, avoid clogging of the filter material, and continuously maintain high dust removal efficiency.

[0050] When the air filtered through the dust particles enters the space between the gauze 3035 and the circular cylinder 301, the operator controls the telescopic rod 20310 through the driving motor 2039 to drive the piston plate 20311 to move downward inside the circular cylinder 301, so that the piston plate 20311 squeezes the air at the bottom of the piston plate 20311 through the guide hole 2037 and enters the guide hole 1 2036, and then enters the absorption slot plate 2035 through the guide hole 1 2036 to absorb the harmful gas, and finally is discharged to the interior of the collection device through the exhaust pipe 2038. The air is squeezed downward by the piston plate 20311, so that the air pressure inside the absorption slot plate 2035 increases, and the air flow rate inside the absorption slot plate 2035 increases, thereby increasing the collision frequency and time of the gas molecules and the activated carbon, thereby improving the activated carbon's absorption effect on harmful gases.

[0051] By linking the telescopic rod, drive motor 2039 and other components through the equipment control device, the full process of dust filtration, harmful gas absorption and filter material cleaning is realized. The structural design of the detachable rubber plate 3034 and the independent absorption trough plate 2035 facilitates subsequent maintenance and replacement, reducing manual maintenance costs and downtime.
