Description

Technical Field

[0001] The invention relates to the technical field of dust reduction in mining, and in particular to dust removal equipment used in mining. Background Art

[0002] A large amount of dust will be generated in the mining process. This dust will cause great harm to human health and the environment. Fog cannons will be used to reduce dust in the air at the mining site. The fog cannon is based on the principle of wind transportation. It first uses advanced high-pressure pumps and fine atomizing nozzles to atomize water, and then uses the fan air volume and wind pressure to send the atomized water mist to a longer distance. When the water mist reaches a longer distance, it adheres to the dust in the air and causes the dust to fall.

[0003] However, in the actual operation of the fog cannon, if a small air volume is used to blow water mist to reduce dust, the spraying distance of the water mist may be limited, and it may not be possible to reduce dust at a long distance. If the air intake volume is increased to increase the spraying range of the water mist, the high-speed wind may blow the dust, and the blown dust may be blown and spread to a distant place. The dust blown to a distant place may not be effectively reduced by the water mist. Therefore, the dust reduction effect of the fog cannon needs to be further improved. Summary of the invention

DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. 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.

[0043] Embodiment 1:

[0044] A dust removal device for mining, comprising:

[0045] A wind tube 2 mounted on the vehicle body 1;

[0046] The sealing push plate 201 is fixedly connected in the air cylinder 2;

[0047] The air injection pipe 401 is fixedly connected to the sealing push plate 201;

[0048] The elastic connecting part 203 is connected to the wind tube 2;

[0049] The first water delivery ring 802 connected with the first nozzle 8021 is fixedly connected to the wind tube 2;

[0050] A mounting plate 8, fixedly connected to the first water delivery ring 802;

[0053] The second water delivery ring 12 is slidably connected to the wind tube 2, and the second water delivery ring 12 is connected to the branch pipe 1201;

[0054] The sealing push plate 201 moves to squeeze the elastic connection part 203 to impact the air in the elastic connection part 203. The air in the elastic connection part 203 is synchronously blown toward the atomized water mist of the first nozzle 8021 along with the wind blown out by the jet pipe 401, thereby increasing the spraying distance of the water mist after blowing and inhibiting the diffusion of dust.

[0055] A support rod 2011 is fixedly connected to the connecting plate 1202, and one end of the support rod 2011 away from the connecting plate 1202 is fixedly connected to the end of the wind tube 2 on the left side of the elastic component.

[0056] Reference Figure 4-Figure 6 The air duct 2 is composed of a cylinder body 202 at both ends and an elastic connecting portion 203 in the middle, and the elastic connecting portion 203 is fixedly connected to the cylinder bodies 202 at both sides.

[0057] It should be noted that the support rod 2011 is fixedly connected to the left cylinder 202 , and the right cylinder 202 is connected to the bracket 3 .

[0058] It should also be noted that the air injection pipe 401 is an elastic hose available on the market, and the elastic connecting portion 203 is an elastic wear-resistant bag available on the market.

[0059] Reference Figure 4 , Figure 7 , Figure 8 A driving cylinder 9 is fixedly connected to the mounting plate 8, and a first sliding cavity 901 and a second sliding cavity 902 are separated in the driving cylinder 9 by a baffle 903. A connecting pipe 904 is fixedly connected to the side wall of the driving cylinder 9. The first sliding cavity 901 is connected to the second sliding cavity 902 through the connecting pipe 904. A second sliding plug 9021 is slidably connected in the second sliding cavity 902. A pull rope 14 is fixedly connected to the second sliding plug 9021, and one end of the pull rope 14 away from the second sliding plug 9021 is fixedly connected to the branch pipe 1201.

[0060] Reference Figure 8A first sliding plug 9011 is slidably connected in the first sliding cavity 901, a push rod 9012 is fixedly connected to the first sliding plug 9011, and a driving plate 9013 is fixedly connected to one end of the push rod 9012 away from the first sliding plug 9011, and the driving plate 9013 is against the second water delivery ring 12.

[0061] Reference Figure 7 A magnet 9014 is fixedly connected to the driving plate 9013 , the second water supply ring 12 is an iron ring, and the second water supply ring 12 and the magnet 9014 are attracted to each other.

[0062] The mounting plate 8 is fixedly connected to a support plate 801 , the support plate 801 is fixedly connected to an electric push rod 10 , the driving end of the electric push rod 10 is fixedly connected to a driving rod 1001 , the driving rod 1001 is fixedly connected to a connecting plate 1202 , and the connecting plate 1202 is fixedly connected to the second water supply ring 12 .

[0063] Reference Figure 2 , Figure 3 A water pump 103 and a water tank 101 are fixedly connected in the vehicle body 1, a water pipe 1031 is connected to the liquid inlet end of the water pump 103, the water pipe 1031 is connected to the water tank 101, a three-way pipe 11 is fixedly connected to the liquid outlet end of the water pump 103, a first liquid infusion pipe 6 and a second liquid infusion pipe 7 are fixedly connected to the three-way pipe 11, the first liquid infusion pipe 6 is connected to the second water infusion ring 12, and the second liquid infusion pipe 7 is connected to the first water infusion ring 802.

[0064] Reference Figure 1-Figure 8 During use, air is blown into the air duct 2 through the fan 4 and the jet pipe 401, and at the same time, the clean water in the water tank 101 is drawn by the water pump 103 and input into the first water supply ring 802 and the second water supply ring 12. The clean water input into the first water supply ring 802 is sprayed out through the first nozzle 8021, and the clean water input into the second water supply ring 12 is sprayed out through the second nozzle 13 after passing through the branch pipe 1201. The wind sprayed from the air duct 2 will blow the water mist sprayed from the first nozzle 8021 and the second nozzle 13, thereby driving the water mist to blow toward the dust group, and the dust group is effectively dusted by the contact between the blown water mist and the dust group.

[0065] Reference Figure 5-Figure 9During the dust reduction process, when the infrared dust sensor 102 detects that there is a tendency for dust to spread, the infrared dust sensor 102 transmits a signal to the controller, and the controller controls the electric push rod 10 to work. The electric push rod 10 will pull the second water delivery ring 12 to move, and the second water delivery ring 12 will pull the left cylinder 202 to move through the support rod 2011. The movement of the left cylinder 202 will drive the sealing push plate 201 fixedly connected thereto to move quickly. The fast-moving sealing push plate 201 will press the gas in the elastic connection part 203, thereby achieving the effect of pressurizing the gas in the elastic connection part 203. At this time, the pressurized gas and the gas ejected from the jet pipe 401 will be instantly blown out through the wind tube 2, and the blown wind will improve the blowing effect on the water mist, and at this time the water mist will be sprayed to the dust farther away;

[0066] When the elastic connection part 203 is compressed, the controller will control the electric push rod 10 to push and reset the second water delivery ring 12. The reset second water delivery ring 12 will then drive the sealing push plate 201 to reset. When the sealing push plate 201 is reset, the blowing effect of the wind tube 2 on the water mist is reduced, and the water mist will be sprayed toward the nearby dust.

[0067] The reciprocating movement of the sealing push plate 201 changes the spraying distance of the water mist blown out by the air cylinder 2, thereby being able to perform dust reduction treatment on dust at different distances.

[0068] Reference Figure 4-Figure 9 When the sealing push plate 201 moves to the right, the movement of the second water delivery ring 12 will also synchronously push the branch pipe 1201 to move. At this time, the branch pipe 1201 is limited and squeezed by the limiting groove 803 opened on the mounting plate 8. At this time, the branch pipe 1201 will slide out, and the sliding extension of the branch pipe 1201 will synchronously drive the second nozzle 13 to rise and extend.

[0069] During the movement of the second water delivery ring 12, after the second water delivery ring 12 moves a certain distance, the second water delivery ring 12 will collide with the driving plate 9013. At this time, the movement of the second water delivery ring 12 will push the driving plate 9013 to move. The movement of the driving plate 9013 will push the first sliding plug 9011 to slide. The sliding of the first sliding plug 9011 will squeeze out the gas in the first sliding cavity 901. The squeezed gas will flow into the second sliding cavity 902 through the connecting pipe 904. At this time, the squeezed gas will push the second sliding plug 9021 to slide to the left. The second sliding plug 9021 slides to the left, which will pull the pull rope 14 to move. The pulling of the pull rope 14 will synchronously pull the branch pipe 1201. At this time, the end of the branch pipe 1201 close to the second nozzle 13 will be bent. At this time, the water mist sprayed by the second nozzle 13 will be gathered and sprayed towards the water mist sprayed by the first nozzle 8021. At this time, the pressurized gas sprayed by the wind tube 2 will blow the gathered water mist, and more water mist will be sprayed towards the dust in the distance, thereby further improving the dust reduction treatment effect on the dust in the distance and further suppressing the diffusion of the dust in the distance.

[0070] It should be noted that when the sealing push plate 201 is reset, the electric push rod 10 pushes the second water supply ring 12 to reset synchronously, and the reset of the second water supply ring 12 will synchronously pull the first sliding plug 9011 to reset. At this time, after the second water supply ring 12 moves a certain distance, the second water supply ring 12 will pull the first sliding plug 9011 to abut against the inner wall of the first sliding cavity 901. At this time, when the second water supply ring 12 moves again, the second water supply ring 12 will separate from the magnet 9014 on the driving plate 9013;

[0071] It should also be noted that an electromagnetic pressure relief valve is provided on the exhaust pipe connected to the second slide cavity 902. When the first slide plug 9011 is reset, the electromagnetic pressure relief valve is opened. At this time, the gas in the second slide cavity 902 is discharged through the exhaust pipe. At this time, the second slide plug 9021 is synchronously reset under the action of the spring 9022. At this time, the second slide plug 9021 is reset and no longer pulls the pull rope 14. At this time, the branch pipe 1201 returns to its original state under its own elastic force.

[0072] It should be noted that the first nozzle 8021 and the second nozzle 13 are both atomizing nozzles available on the market.

[0073] The branch pipe 1201 is a carbon fiber tube.

[0074] By configuring the branch pipe 1201 as a carbon fiber tube, the branch pipe 1201 can be squeezed and slid out stably, while ensuring the wear resistance of the branch pipe 1201 and extending the service life of the branch pipe 1201.

[0075] A spring 9022 is fixedly connected to the second sliding plug 9021 , and one end of the spring 9022 away from the second sliding plug 9021 is fixedly connected to the baffle 903 .

[0076] Reference Figure 7 , Figure 8 Two sets of exhaust pipes are fixedly connected to the side wall of the driving cylinder 9, and the two sets of exhaust pipes are respectively connected to the first sliding cavity 901 and the second sliding cavity 902, and the exhaust pipe connected to the second sliding cavity 902 is placed on the right side of the second sliding plug 9021, and both the exhaust pipe and the connecting pipe 904 are provided with a one-way valve.

[0077] The sealing push plate 201 provided in the device and capable of following the movement of the cylinder 1 reciprocates to pressurize the gas in the wind tube 2, so that the water mist blown out of the wind tube 2 is sprayed on the dust from near to far, and dust reduction treatment can be performed on dust at different distances. At the same time, the problem in the prior art that the wind tube 2 may blow nearby dust to far away when blowing out water mist is solved, which easily causes the dust to spread to far away and cannot effectively reduce dust.

[0078] At the same time, through the slidable branch pipe 1201 provided in the device, when the branch pipe 1201 is not extended and is in the initial state, the first nozzle 8021 and the second nozzle 13 are used in combination to effectively increase the atomization area of ​​the water mist, thereby increasing the dust reduction area for dust; when the branch pipe 1201 is extended in conjunction with the sealing push plate 201, the second nozzle 8021 can be pulled toward the water mist sprayed by the first nozzle 13, thereby making the water mist sprayed by the second nozzle 8021 and the water mist sprayed by the first nozzle 13 gather together, thereby increasing the amount of water mist sprayed by the wind tube 2 toward the distant dust, thereby improving the dust reduction effect on the distant dust.

[0079] Embodiment 2:

[0080] Reference Figure 1-Figure 2 , a dust removal equipment for mining, is basically the same as Example 1, and further, a driving motor 5 is fixedly connected to the bracket 3, and the driving end of the driving motor 5 is connected to the rotating rod on the wind tube 2. When the sealing push plate 201 slides toward the first nozzle 8021, the driving motor 5 rotates synchronously, and the driving motor 5 will drive the wind tube 2 to rotate. At this time, one side of the first nozzle 8021 will be tilted higher than one side of the jet pipe 401. At this time, the water mist blown out of the wind tube 2 can be sprayed farther, thereby further suppressing the diffusion of dust in the distance.

[0081] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0082] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
