Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and dust removal, in particular to a ventilation and dust removal device for a coal mine. Background Art

[0002] During the coal mining process, a large amount of dust is generated. This dust not only poses a serious threat to the health of miners, causing occupational diseases such as pneumoconiosis, but also affects the safe production and working environment of coal mines.

[0003] With the continuous expansion of coal mining scale and the increasing requirements for safety and environmental protection, ventilation and dust removal have become important operations in coal mines. Traditional coal mine ventilation systems mainly focus on providing fresh air and exhausting harmful gases underground, but their effect on dust treatment is limited. Early simple ventilation methods relied solely on the dilution effect of airflow, making it difficult to effectively capture and remove fine dust particles.

[0004] In order to improve the dust removal effect, some coal mines have begun to use relatively primitive dust removal devices to achieve gas-solid separation. However, the dust removal efficiency of this dust collector is reduced, which increases the operating cost and maintenance workload. It cannot effectively convert the intercepted dust into a mud-water mixture for easy processing. The effect of ventilation and dust removal in coal mines needs to be improved. In view of this, we propose a coal mine ventilation and dust removal device. Utility Model Content

The two groups of side pipes 112 and the gas valve 113 can easily adjust the ventilation intensity. The corresponding gas valve 113 can be opened according to the situation. The end of the air inlet pipe 111 away from the side pipe 112 is fixedly installed with a top pipe 119, and a liquid valve 1110 is provided on the top pipe 119. The top cover 4 is fixedly installed with an N-shaped pipe 1111. There are three groups of N-shaped pipes 1111.

The inner side of the bottom end of the N-shaped tube 1111 is clamped with a circular filter plate 1112. The circular filter plate 1112 is located on the inner side of the rectangular cover 2 and above the rectangular filter 10. When the air supply equipment stops supplying air, the liquid valve 1110 is opened and the gas valve 113 is closed. The water body passes through the air inlet pipe 111 and the top pipe 119 through the water supply equipment and flows into the three groups of N-shaped tubes 1111, and cooperates with the circular filter plate 1112 to prevent fine dust from entering the inside of the N-shaped tube 1111, and then sprayed on the rectangular filter 10, turning the dust intercepted by the rectangular filter 10 into a mud-water mixture for subsequent treatment.

[0033] In one embodiment of the present invention, an auxiliary component 12 is provided at the bottom end of the conical cover 3, and the auxiliary component 12 includes a main motor 121, and the main motor 121 is fixedly installed on the outside of one end of the conical cover 3, and the output end of the main motor 121 is fixedly installed with a dragon rod 122, and the dragon rod 122 is rotatably installed on the inside of the conical cover 3. In addition, a discharge hopper 123 is fixedly installed on the outside of the other end of the conical cover 3. Furthermore, the mud and water mixture generated by the cleaning component 11 gathers at the bottom of the conical cover 3. When the main motor 121 is started, the dragon rod 122 rotates inside the conical cover 3 to push the mud and water mixture to the discharge hopper 123. A secondary motor 124 is fixedly installed on the outside of the discharge hopper 123, and a rotating shaft is fixedly installed on the output end of the secondary motor 124. 125. The rotating shaft 125 is rotatably installed on the inner side of the discharge hopper 123. A collecting device is provided in the coal mine at the bottom end of the discharge hopper 123. A discharge plate 126 is fixedly installed on the outer side of the rotating shaft 125. There are multiple groups of discharge plates 126, and multiple groups of discharge plates 126 are arranged in a circular array on the outer side of the rotating shaft 125. When the secondary motor 124 is started, the rotating shaft 125 rotates on the inner side of the discharge hopper 123, driving the discharge plates 126 to rotate, thereby discharging the mud and water mixture in the discharge hopper 123 to the collecting device located in the coal mine at the bottom end of the discharge hopper 123, thereby completing the auxiliary cleaning work in the entire ventilation and dust removal process, making the ventilation and dust removal effect of the coal mine better, and preventing dust and mud and water mixture from accumulating in the device and affecting the performance of the device and the dust removal effect.

[0034] Working principle: The dust-laden gas in the coal mine first enters the device body through the air inlet hood 5. The rectangular grille 6 on the air inlet hood 5 can intercept impurities with large particle size to prevent them from entering the subsequent equipment and causing blockage and other problems. The dust-laden gas then enters the inside of the rectangular hood 2 and the conical hood 3. The rectangular filter 10 will intercept the dust in the dust-laden gas inside the device body. The filtered gas enters the air outlet 7 through the rectangular frame 8, and is then discharged to the treatment equipment outside the coal mine by the exhaust pipe 9, thereby realizing the function of separating the dust in the dust-laden gas and discharging the purified gas. When fresh air needs to be transported into the coal mine, the air and water supply equipment outside the coal mine transports gas through the air inlet pipe 111. At this time, the top of the air inlet pipe 111 is connected to the air supply equipment, the liquid valve 1110 is closed, the gas valve 113 is opened, and fresh air enters the inside of the side pipe 112, and then passes The bend pipe 114 and the conical bucket 115 discharge to the interior of the mine, and cooperate with the ventilation filter plate 116 to prevent external impurities from entering the conical bucket 115. The airflow will drive the impeller 118 and the rotating rod 117 to rotate, so that the ventilation filter plate 116 is not easy to be blocked, and the fresh air can be diffused over a wider range. The two sets of side pipes 112 and the gas valve 113 can easily adjust the ventilation intensity. The corresponding gas valve 113 can be opened according to the situation. When the air supply equipment suspends air supply, the liquid valve 1110 is opened and the gas valve 113 is closed. The water body passes through the air inlet pipe 111 and the top pipe 119 through the water supply equipment and flows into the three sets of N-shaped pipes 1111. Cooperating with the circular filter plate 1112, fine dust is prevented from entering the inside of the N-shaped pipe 1111, and then sprayed on the rectangular filter screen 10, and the dust intercepted by the rectangular filter screen 10 is turned into a mud-water mixture for subsequent treatment.

[0035] Furthermore, the mud-water mixture generated by the cleaning component 11 gathers at the bottom of the conical cover 3. When the main motor 121 is started, the auger rod 122 rotates inside the conical cover 3, pushing the mud-water mixture to the discharge hopper 123. When the secondary motor 124 is started, the rotating shaft 125 rotates inside the discharge hopper 123, driving the discharge plate 126 to rotate, thereby discharging the mud-water mixture in the discharge hopper 123 to the collection equipment located in the coal mine at the bottom of the discharge hopper 123, thereby completing the auxiliary cleaning work in the entire ventilation and dust removal process.

[0036] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
