Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0048] Example:

[0049] Reference Figure 1-Figure 11 A dust removal and ventilation device for mine environmental protection comprises a wind tube 2 mounted on a bracket 1, and further comprises:

[0050] The detection unit 202 is fixedly connected in the wind tube 2;

[0051] The mounting frame 203 is fixedly connected in the wind tube 2;

[0052] The driving motor 3 is fixedly connected to the mounting frame 203;

[0053] The suction blade 301 is fixedly connected to the driving end of the driving motor 3;

[0054] The first filter plate 7 is fixedly connected in the air cylinder 2;

[0055] The first filter hole 701 is provided on the first filter plate 7;

[0056] The second filter plate 9 is slidably connected in the air cylinder 2;

[0057] The second filter hole 901 is provided on the second filter plate 9;

[0058] The first filter hole 701 and the second filter hole 901 are both tapered holes, and the aperture size gradually decreases from left to right;

[0059] When the first filter plate 7 and the second filter plate 9 are attached to each other, the air outlet end of the first filter hole 701 and the air inlet end of the second filter hole 901 are the same size;

[0060] The first capsule 10 is fixedly connected in the first filter hole 701;

[0061] The second capsule 11 is fixedly connected in the second filter hole 901;

[0062] When mining is carried out in the mine, the second filter plate 9 slides, the first filter plate 7 and the second filter plate 9 are separated, the first capsule 10 and the second capsule 11 are filled with water and swelled at the same time, the inner diameter of the swollen first capsule 10 is the same as the diameter of the air outlet end of the first filter hole 701, the inner diameter of the swollen second capsule 11 is the same as the diameter of the air outlet end of the second filter hole 901, the suction blade 301 rotates, and the air in the mine is discharged through the first filter hole 701 and the second filter hole 901 in turn. During the exhaust process, the first capsule 10 and the second capsule 11 swell to filter particulate impurities in the air;

[0063] When no mining is carried out in the mine, the second filter plate 9 is reset to move closer to the first filter plate 7, the first capsule 10 and the second capsule 11 are reset and contracted, impurities in the first filter hole 701 and the second filter hole 901 slide down along the two groups of conical filter holes, the suction blade 301 rotates, and the air in the mine is quickly discharged through the first filter hole 701 and the second filter hole 901.

[0064] It should be noted that the detection unit 202 is a particle concentration detector available on the market.

[0065] Reference Figure 1-Figure 11 When no mining is carried out in the mine, the dust content in the air in the mine is low. At this time, the detection unit 202 detects that the dust content in the air is low and meets the emission requirements. At this time, the first magnet 702 is connected to the positive current. At this time, the first magnet 702 and the second magnet 902 are attracted to each other, and the first filter plate 7 and the second filter plate 9 are closely attached. At this time, the suction blade 301 rotates, and the air inside the mine is sucked out through the wind tube 2. Since the first filter hole 701 and the second filter hole 901 are both conical holes, the air sucked into the wind tube 2 is discharged through the first filter hole 701 and the second filter hole 901;

[0066] When mining is carried out in the mine, the dust content in the air in the mine is high. At this time, the detection unit 202 detects that the dust content in the air is high and does not meet the emission requirements. At this time, the first magnet 702 is connected to the reverse current. At this time, the first magnet 702 and the second magnet 902 repel each other, and the second filter plate 9 will slide and separate from the first filter plate 7;

[0067] A two-way delivery pipe 206 is fixedly connected to the air duct 2, one end of the two-way delivery pipe 206 is connected to the first water storage chamber 602, and the other end of the two-way delivery pipe 206 is connected to the second water storage chamber 802. A two-way connecting pipe 207 is fixedly connected to the bottom of the two-way delivery pipe 206, and the first delivery pipe 2071 and the second delivery pipe 2072 are symmetrically connected on the side wall of the two-way connecting pipe 207.

[0068] It should be noted that valves are provided on both the first delivery pipe 2071 and the second delivery pipe 2072, and the valves are solenoid valves available on the market.

[0069] Reference Figure 4 , Figure 5 The first delivery pipe 2071 is connected to the external air pump and is used to inflate and pressurize the first water storage chamber 602 and the second water storage chamber 802; the second delivery pipe 2072 is connected to the external delivery pump, and the delivery pump can draw external water to replenish the first water storage chamber 602 and the second water storage chamber 802.

[0070] Reference Figure 4-Figure 8 When the second filter plate 9 slides and separates, the valve on the first delivery pipe 2071 is opened, and the external air pump pressurizes the first water box 6 and the second water box 8 through the first delivery pipe 2071 and the two-way delivery pipe 206. At this time, the pressure valves of the first water delivery pipe 1002 and the second water delivery pipe 1102 will be opened, and the first capsule 10 and the second capsule 11 will be filled with water and swell;

[0071] Reference Fig.10 , Fig.11 When the first capsule 10 is inflated, the inner diameter of the inflated first capsule 10 is the same as the diameter of the air outlet end of the first filter hole 701, and the air is discharged through the first filter hole 701;

[0072] When the first capsule 10 is inflated, the overall size of the air inlet end of the first filter hole 701 is reduced, thereby being able to effectively block and filter particulate impurities in the air, thereby achieving the effect of particle dust removal.

[0073] When the second capsule 11 is inflated, the inner diameter of the inflated second capsule 11 is the same as the diameter of the air outlet end of the second filter hole 901, and the air that has been initially filtered can be discharged through the second filter hole 901;

[0074] When the second capsule 11 is inflated, the overall size of the air inlet end of the second filter hole 901 is reduced, thereby being able to further block small particle impurities in the filtered air, thereby further improving the particle dust removal effect.

[0075] Reference Figure 5-Figure 8When working in the mine, when the first filter plate 7 and the second filter plate 9 in the device are separated, the first capsule 10 in the first filter plate 7 and the second capsule 11 in the second filter plate 9 swell at the same time, and the first filter hole 701 on the first filter plate 7 is larger than the second filter hole 901 on the first filter plate 9. At this time, the first filter plate 7 can achieve preliminary filtration of the air, and the air after preliminary filtration can be further filtered for the second time when passing through the second filter plate 9, and the small particle impurities in the air are further filtered out; when not working in the mine, the second filter plate 9 moves closer to the first filter plate 7 and resets. At this time, the first capsule 10 in the first filter plate 7 and the second capsule 11 in the second filter plate 9 shrink and reset synchronously. At this time, the size of the air inlet end of the two groups of filter holes becomes larger again. At this time, the particle impurities stuck in the two groups of filter holes will slide along the filter holes, thereby being able to play the effect of cleaning the filter holes, reducing the possibility of particle impurities clogging the filter holes.

[0076] By means of the first capsule 10 and the second capsule 11 provided in the device, the first filter hole 701 and the second filter hole 11 can be cleaned simultaneously when the two groups of filter plates are close to each other. Therefore, the two groups of filter plates do not need to be equipped with separate backwashing equipment, which effectively reduces the ventilation cost.

[0077] It should be noted that after the device has been working for a period of time, the staff can remove the first filter plate 7 and the second filter plate 9 in the air duct 2. During the process of removing the two groups of filter plates, the staff can actively clean the filtered impurities in the air duct 2. The cleaned impurities mainly include the impurities filtered on the left side of the two groups of first filter plates 7 and the impurities that slide along the first filter hole 701 when the first capsule 10 shrinks and resets. When the first filter plate 7 is removed, the impurities filtered on the left side of the second filter plate 9 and the impurities that slide along the second filter hole 901 when the second capsule 11 shrinks and resets can be cleaned to ensure that the filtered impurities in the air duct 2 will not accumulate and to ensure that the subsequent second filter plate 9 can slide stably.

[0078] It should be noted that in order to ensure that each group of first and second bladders 10, 11 can be fully inflated, the pressure valves on the first and second water pipes 1002, 1102 can be opened in sequence from top to bottom. At this time, the first and second bladders 10, 11 can be inflated in sequence from top to bottom.

[0079] The first filter plate 7 is fixedly connected to a first water box 6 , in which a first water storage cavity 602 is provided. The first capsule 10 is fixedly connected to a first water pipe 1002 , which is in communication with the first water storage cavity 602 .

[0080] The second filter plate 9 is fixedly connected with a second water box 8 , in which a second water storage chamber 802 is provided. The second capsule 11 is fixedly connected with a second water pipe 1102 , which is in communication with the second water storage chamber 802 .

[0081] Reference Figure 5-Figure 9 The first water box 6 is provided with a first ventilation hole 601, and the diameter of the first ventilation hole 601 is the same as the size of the air inlet end of the first filter hole 701; the second water box 8 is provided with a second ventilation hole 801, and the diameter of the second ventilation hole 801 is the same as the size of the air outlet end of the second filter hole 901.

[0082] It should be noted that both the first water pipe 1002 and the second water pipe 1102 are provided with a one-way pressure control valve, and the pressure control valve is an electrically controlled valve available on the market.

[0083] An air inlet pipe 201 is fixedly connected to the air duct 2, a water pump 5 is fixedly connected to the top of the air duct 2, a cooling pipe 4 is fixedly connected to the air duct 2, a third water pipe 502 is fixedly connected to the water outlet end of the water pump 5, the third water pipe 502 is connected to the cooling pipe 4, a three-way pipe is connected to the water inlet end of the water pump 5, the three-way pipe is connected to the fourth water pipe 503, and the end of the fourth water pipe 503 away from the water pump 5 is connected to the second water storage chamber 802.

[0084] It should be noted that the size and number of the air inlet pipes 201 can be selected and adjusted according to the ventilation volume requirements. When multiple groups of air inlet pipes 201 are provided, the multiple groups of air inlet pipes 201 are evenly distributed on the wind tube 2, and multiple groups of cooling pipes 4 and second water pipes 502 can be provided and correspond to the air inlet pipes 201.

[0085] Reference Figure 5 The three-way pipe is also connected to a fifth water pipe 501 , and one end of the fifth water pipe 501 away from the water pump 5 is connected to the first water storage chamber 602 .

[0086] The cooling pipe 4 is fixedly connected with an atomizing nozzle 401 .

[0087] When the first sac 10 and the second sac 11 shrink and reset, the water pump 5 draws water from the second water box 8 and the first water box 6 through the fourth water pipe 503 and the fifth water pipe 501 respectively, and the drawn water will be input into the cooling pipe 4 through the third water pipe 502, and finally sprayed out through the atomizing nozzle 401 at the tail end of the cooling pipe 4. The clean water sprayed by the atomizing nozzle 401 can be sprayed on the sucked gas, and then the sprayed gas can be subjected to dust reduction treatment, further settling the fine dust discharged in the air.

[0088] Reference Figure 5 It should be noted that the cooling pipe 4 is attached to the outer wall of the air inlet pipe 201;

[0089] Reference Figure 4 , Figure 5 When the extracted water flows through the cooling pipe 4, the flowing water will cool the air inlet pipe 201, and then cool the air input by the air inlet pipe 201, and then reduce the temperature of the input air, thereby effectively alleviating the high temperature environment underground.

[0090] It should also be noted that the third water pipe 502, the fourth water pipe 503 and the bidirectional water pipe 206 are all elastic hoses.

[0091] A first magnet 702 is fixedly connected to the first filter plate 7 , and a second magnet 902 is fixedly connected to the second filter plate 9 . The first magnet 702 matches the second magnet 902 .

[0092] A sliding rod 205 is fixedly connected in the air duct 2, the second filter plate 9 is slidably connected to the sliding rod 205, a limiting plate 204 is fixedly connected to the sliding rod 205, a third magnet 2041 is fixedly connected to the limiting plate 204, a fourth magnet 803 is fixedly connected to the second water box 8, and the third magnet 2041 and the fourth magnet 803 attract each other.

[0093] The second water box 8 is fixedly connected with a spring 2042 , and one end of the spring 2042 away from the second water box 8 is fixedly connected to the limiting plate 204 .

[0094] It should be noted that both the first magnet 702 and the third magnet 2041 are electromagnets.

[0095] Reference Figure 2-Figure 4 When the detection unit 202 detects that the particle concentration in the air is reduced to the emission standard, the third magnet 2041 is powered off, and the third magnet 2041 and the fourth magnet 803 will no longer attract each other. At this time, under the elastic force of the spring 2042, the second water box 8 is pushed to reset;

[0096] Reference Figure 2-Figure 6 , the second water box 8 is reset and synchronously pushes the second filter plate 9 to slide and reset. After the second filter plate 9 slides for a distance, the first magnet 702 is energized in the positive direction again. At this time, the first magnet 702 will attract the second magnet 902 on the second filter plate 9. At this time, the second filter plate 9 will slide closer to the first filter plate 7. When the first magnet 702 and the second magnet 902 attract each other, the second filter plate 9 and the first filter plate 7 are attached to each other. At this time, the air can continue to be quickly exhausted through the first filter hole 701 and the second filter hole 901.

[0097] Reference Figure 7 , Figure 8 The first drain pipe 1001 and the second drain pipe 1101 are both provided with a pressure relief valve, and the pressure relief valve is an electromagnetic one-way pressure relief valve available on the market.

[0098] It should also be noted that the first bladder body 10 and the second bladder body 11 are both elastic water bladders available on the market.

[0099] A first drainage pipe 1001 is fixedly connected to the first bladder body 10 , and the first drainage pipe 1001 is communicated with the first water storage chamber 602 ; a second drainage pipe 1101 is fixedly connected to the second bladder body 11 , and the second drainage pipe 1101 is communicated with the second water storage chamber 802 .

[0100] Reference Figure 6-Figure 8 When the second filter plate 9 is reset, the pressure relief valves on the first drain pipe 1001 and the second drain pipe 1101 are opened synchronously, and the water in the first capsule 10 and the second capsule 11 will be discharged through the first drain pipe 1001 and the second drain pipe 1101. Since the first capsule 10 and the second capsule 11 are elastic, the first capsule 10 and the second capsule 11 will shrink and reset during the drainage process, and the squeezing force during the reset can quickly squeeze out the water in the first capsule 10 and the second capsule 11;

[0101] Reference Figure 8 , the water discharged through the first drainage pipe 1001 will flow back into the first water storage chamber 602;

[0102] Reference Figure 6 , Figure 7 , the water discharged through the second drainage pipe 1101 will flow back to the second water storage chamber 802.

[0103] The multiple groups of filter plates arranged in the device can effectively filter impurities in the air extracted from the mine, thereby ensuring the dust removal effect of the air during ventilation. At the same time, the two groups of capsules arranged on the two groups of filter plates can shrink and reset when the two groups of filter plates are close to each other. At this time, the filtered impurities can slide along the tapered holes when the capsules expand. There is no need to add backwashing equipment on the filter plates, which effectively reduces the ventilation and filtration costs.
