The dust sticking plate 231 is parallel to the filter screen 21 and is located on the horizontal side of the filter screen 21.
[0034] The dust collecting base 3 is arranged below the dust removal part 2 and is used for collecting dust cleaned by the dust removal part 2.
[0035] Principle of use: when the coal mining operation needs to be ventilated, the dust-containing air is driven by the first fan 11, passes through the filter screen 21, the dust in the air is intercepted by the filter screen 21, the air from which the dust is removed is discharged from the equipment by the second fan 12, the reciprocating driving device 221 is started to drive the brush 222 to clean the filter screen 21, and the dust swept off is partially directly fallen into the dust collecting base 3 below, and the other part of the dust is carried by the brush 222, the brush 222 carrying the dust contacts and rubs against the dust sticking plate 231 in the reciprocating movement track, the dust on the bristles is stuck by the dust sticking plate 231, and the cleaning of the brush 222 is ensured.
[0036] In this way, the reciprocating driving device 221 drives the brush 222 to clean the filter screen 21, when the brush 222 carries dust after cleaning the filter screen 21, the dust on the brush 222 is stuck by the dust sticking plate 231, so that the brush 222 does not carry the dust back to the filter screen 21 in the return process or the dust is not raised again into the air duct, the secondary dust raising is effectively prevented, and the dust removal effect is further improved.
[0037] In the above technical solution, the dust contains hard particles, which may cause abrasion to the bristles in the process of repeated friction of the brush 222 and the filter screen 21, reduce the service life of the brush 222, the dust is stuck in time by the dust sticking plate 231, the abrasion is reduced, the cleaning and normal working state of the brush 222 can be maintained.
[0038] Preferably, the surface of the dust sticking plate 231 for contacting the brush 222 is a round hair surface of a magic tape.
[0039] Specifically, the round hair surface of the magic tape is composed of many fine fiber fluffs, the fluffs have abundant micro surface area, when the brush 222 carrying dust passes, the dust particles can be embedded in the gap between the fluffs, have strong dust sticking capacity, can effectively clean the bristles and will not cause damage to the bristles.
[0040] Reference Figure 2Further, the cleaning brush assembly 23 further comprises a scraping plate 232 and a vertical driving device 233, the vertical driving device 233 is capable of driving the scraping plate 232 to lift and scrape the dust sticking plate 231, and the scraping plate 232 is used to scrape off the dust on the dust sticking plate 231.
[0041] Specifically, as the dust sticking plate 231 is used for a long time, a large amount of dust will accumulate on the surface of the dust sticking plate 231, which will cause the adhesion to decrease and affect the adsorption effect of the brush 222 on the dust. The scraping plate 232 is driven by the vertical driving device 233 to scrape the dust sticking plate 231, which can effectively remove the dust on the surface of the dust sticking plate 231, so that the adhesion surface of the dust sticking plate 231 is exposed again and the dust sticking ability of the dust sticking plate 231 is restored. Moreover, the scraping plate 232 and the vertical driving device 233 can be operated at the same time as the mesh brush assembly 22, so that the cleaning of the dust sticking plate 231 can be completed without stopping the ventilation operation.

[0042] Referring to Figure 2 Further, the dust removal part 2 further comprises a water curtain dust removal assembly 24, the water curtain dust removal assembly 24 comprises a water storage tank 241, a water pipe 242, a water pump 243 and a spraying seat 244, the water storage tank 241, the water pipe 242 and the spraying seat 244 are connected in sequence along the water flow direction, the water pump 243 is connected with the water pipe 242, and the spraying seat 244 is used to form a water curtain in the air duct.
[0043] The filter screen 21 and the water curtain are arranged in sequence along the ventilation direction of the air duct.
[0044] Specifically, the filter screen 21 and the water curtain dust removal assembly 24 are arranged in the equipment at the same time, forming multiple dust removal lines. The filter screen 21 can first intercept dust particles with large particle sizes, and the water curtain dust removal assembly 24 can capture fine dust passing through the filter screen 21. When the dust-containing air passes through the water curtain, the dust particles collide with the water droplets and coagulate, and fall under the action of gravity. Moreover, during the water curtain dust removal process, part of the water droplets will combine with the dust particles, so that the humidity of the dust increases. In the process of continuous ventilation, these humid dusts are not easy to be raised again even if they are disturbed by the air flow.
[0045] Referring to Figure 2 Further, the coal mine ventilation equipment convenient for dust prevention further comprises a drying part 4, the drying part 4 comprises an inclined plate 41 and a hydrophobic sponge layer 42 arranged on the inclined plate 41.

[0047] In the above technical scheme, the air after water curtain dust removal carries a large amount of water vapor, and the combination of the inclined plate 41 and the hydrophobic sponge layer 42 can effectively adsorb and remove the water vapor in the air. When the humid air passes through the inclined plate 41, the water vapor will condense on the surface of the inclined plate 41 and be absorbed and guided into the dust collection base 3 by the hydrophobic sponge layer 42, so that the air entering the subsequent ventilation system is drier, preventing the underground equipment from being damp and corroded and improving the comfort of the underground operation environment.
[0048] Referring to Figure 2 Preferably, the brush 222 is drivingly connected with the rotary motor 5, and the bristles of the brush 222 are circumferentially arranged along the rotation direction of the rotary motor 5.
[0049] Specifically, when the brush 222 is drivingly connected with the rotary motor 5 and the bristles are circumferentially arranged along the rotation direction, the brush 222 can clean the filter screen 21 in a circular motion during rotation, and the rotary motion increases the number of contacts between the brush 222 and the filter screen 21 per unit time, so that the cleaning force can be applied more frequently to dust stubbornly adhering to the filter screen 21, thereby improving the cleaning efficiency.
[0050] Referring to Figure 2 Preferably, the bottom of the dust collection base 3 is provided with a leveling mechanism 6.
[0051] The leveling mechanism 6 includes at least four electric push rods 61.
[0052] Specifically, the ground conditions are often uneven in the underground coal mine, and the leveling mechanism 6 provided at the bottom of the dust collection base 3 can effectively adjust the levelness of the dust collection base 3 through the at least four electric push rods 61, thereby ensuring the stability of the equipment.
[0053] Referring to Figure 2 Preferably, each electric push rod 61 is provided with a wheel 62.
[0054] Specifically, in the underground coal mine, the structure of the electric push rod 61 and the wheel 62 enables the position of the ventilation equipment to be adjusted according to the mining progress, ventilation demand changes, equipment maintenance, and the like, thereby improving flexibility and applicability.
[0055] Preferably, the dust collection base 3 is paved with a dust-proof mat.
[0056] Specifically, when the dust falls into the dust collection base 3, the dust-proof mat can act as a physical barrier to prevent airflow during the falling process or external interference airflow from blowing the dust again. The dust-proof mat generally has a rough textured surface and has a certain adsorption property, so that the dust particles are tightly combined with the mat. In addition, the dust-proof mat can adsorb and fix the dust, reduce the residual dust in the dust collection base 3, and more thoroughly remove the dust when cleaning the dust collection base 3.
