Description

Technical Field

[0001] The invention relates to the technical field of coal mining, in particular to a dust removal device for an anti-burst drilling hole. Background Art

[0002] Anti-burst drilling refers to a safety measure taken during coal mining to prevent coal and gas outbursts. The gas pressure in the coal seam is released by drilling, the risk of outbursts is reduced, and the safety of the mine is ensured. When drilling the anti-burst drilling, the coal slag needs to be collected to evaluate the drilling construction effect, predict the danger of outbursts, and verify the effectiveness of the anti-burst measures.

However, the adsorption dust removal will cause the filter to be clogged after long-term use, affecting the dust removal efficiency. The spray type requires water mist spraying, which affects the collection of coal slag, making it difficult to evaluate and predict the drilling hole based on the output of coal slag.

DETAILED DESCRIPTION

[0046] Reference Figure 1-Figure 5 The present invention provides a technical solution: a device for removing dust from the orifice of an anti-burst drilling hole, comprising:

[0047] A movable seat 1, a driving wheel is fixed at the bottom thereof;

[0048] A lifting seat 2 is fixed on the moving seat 1, and a connecting column 3 is fixed at its output end;

[0049] The adjusting plate 4 is rotatably arranged on the connecting column 3, and the adjusting grooves 41 are symmetrically opened on both sides of the adjusting plate 4, and the adjusting plate 4 is limited by the adjusting grooves 41 and the bolts;

[0050] A clamping ring 5, fixed on the adjusting plate 4;

[0051] A dust removal assembly 6 is fixed in the clamping ring 5;

[0052] A cleaning component 7, fixing one end of the dust removal component 6;

[0053] The metering assembly 8 , including a first metering assembly 81 and a second metering assembly 82 , is symmetrically fixed on the dust removal assembly 6 .

[0054] Among them, the device can be moved by the movable seat 1, and the height of the device can be adjusted by the lifting seat 2 to adapt to anti-burst drilling holes in different positions. The working surfaces at different angles can be installed through the adjusting plate 4, so that the dustproof component 6 fits the working surface to improve the dustproof effect, and after the drilling is completed, the residual coal slag on the drill bit can be cleaned by the cleaning component 7 to facilitate the drilling of the next anti-burst hole.

[0055] In this embodiment, the dust removal component 6 includes:

[0056] The outer cylinder 61 is fixed in the clamping ring 5;

[0057] The air inlet 62 is configured as two and is obliquely fixed on the outer cylinder 61;

[0058] The inner cylinder 63 has two ends coaxially fixed in the outer cylinder 61 by sealing rings 64;

[0059] The adjusting assembly 65 is installed on the outer wall of the inner cylinder 63 and is located near the middle of the inner cylinder 63;

[0060] The gas passage 66 is opened between the outer tube 61 and the inner tube 63 .

[0061] That is to say, during dust removal, gas is introduced through the air inlet 62 , and the gas enters the inner tube 63 through the gas channel 66 , thereby guiding the coal slag in the inner tube 63 and allowing the coal slag to enter the metering component 8 .

[0062] As a preferred embodiment, the outer wall of the inner cylinder 63 is symmetrically provided with a first air inlet hole 631 and a second air inlet hole 632 , and the first air inlet hole 631 and the second air inlet hole 632 are both arranged obliquely, and the inclination direction is toward the adjustment component 65 .

[0063] It should be noted that the function of the first air inlet 631 is to guide the coal slag, the function of the second air inlet 632 is to block the coal slag, and the inclination angle of the first air inlet 631 is greater than the inclination angle of the second air inlet 632.

[0064] As a preferred embodiment, the adjustment component 65 includes:

[0065] An adjusting cylinder 651 is fixed to the outer wall of the inner cylinder 63;

[0066] A sliding ring 652, slidably disposed on the outer wall of the inner cylinder 63, and driven by the adjusting cylinder 651;

[0067] The hinge balls 653 are arranged in a circle and are hinged to the inner cylinder 63;

[0068] An air inlet pipe 654 is fixed in the hinge ball 653;

[0069] The air inlet head 655 is fixed to one end of the air inlet pipe 654 close to the outer tube 61 and is funnel-shaped;

[0070] The driving assembly is configured as a plurality, installed between the plurality of the air inlet pipes 654 , and driven by the sliding ring 652 .

[0071] It should be noted that the outer diameter of the sliding ring 652 is smaller than the inner diameter of the outer cylinder 61 , so as to facilitate the passage of gas.

[0072] As a preferred embodiment, two sliding grooves 656 are symmetrically provided on both sides of the air inlet pipe 654, and a sliding member 657 is slidably provided on the sliding groove 656. A rotating column 658 is rotatably provided at one end of the sliding member 657 away from each other, and an adjusting column 659 is slidably provided inside the rotating column 658. A positioning member 6510 is rotatably provided at the middle position of the adjusting column 659, and a pull rod 6511 is fixed on the positioning member 6510, and the pull rod 6511 is fixedly connected to the sliding ring 652.

[0073] Among them, when the coal slag needs to enter the first metering component 81, the cylinder body 651 is adjusted to push the sliding ring 652 to tilt the multiple air inlet pipes 654 toward the first metering component 81, thereby forming an air flow barrier to block the coal slag and facilitate the coal slag to enter the first metering component 81. It should be noted that the inclination angle of the air inlet pipe 654 is smaller than the inclination angle of the first air inlet hole 631 to avoid the backflow of coal slag.

[0074] When the coal slag needs to enter the second metering component 82, the cylinder body 651 is adjusted to pull the sliding ring 652, so that the multiple air inlet pipes 654 are tilted toward the second metering component 82, thereby guiding the coal slag to facilitate the coal slag to enter the second metering component 82. It should be noted that the inclination angle of the air inlet pipe 654 is the same as the inclination angle of the first air inlet hole 631, so as to facilitate the guidance of the coal slag.

[0075] In this embodiment, the cleaning component 7 includes:

[0076] A connecting tube 71 is fixed to one end of the dust removal assembly 6;

[0077] The cleaning fans 72 are configured as a plurality and are arranged circumferentially on the connecting tube 71 , and the cleaning fans 72 are arranged obliquely toward the dust removal assembly 6 .

[0078] That is to say, after drilling is completed, the cleaning fan 72 can be used to clean the remaining coal slag on the drill bit, and the coal slag can enter the second metering component 82, thereby further improving the dust removal effect.

[0079] In this embodiment, the first metering component 81 and the second metering component 82 have the same structure, and both include:

[0080] A connecting bin 821 is fixed on the dust removal assembly 6;

[0081] The clamping plate 822 is symmetrically arranged on the lower end surface of the connecting chamber 821;

[0082] A fixing bar 823, fixed in the connecting compartment 821;

[0083] The driving compartment 824 is fixed on the fixing bar 823 and has a lifting motor fixed inside;

[0084] The blocking plate 825 is fixed on the output end of the lifting motor.

[0085] As a preferred embodiment, the clamping plate 822 is slidably provided with a collecting bin, a weighing device is installed in the collecting bin, and the two lifting motors in the first metering component 81 and the second metering component 82 work alternately.

[0086] That is to say, the two collecting bins can be opened and closed alternately through the alternating operation of the lifting motors, thereby alternating every 1m of drilling depth, which is convenient for evaluating the anti-blowout hole to prevent the coal seam from not being penetrated or encountering a fault.

[0087] Specifically, firstly, the device is moved to the position to be drilled by the moving seat 1, and then the height of the device is adjusted by the lifting seat 2, so that the dustproof component 6 is aligned with the anti-burst drilling hole, and then the dustproof component 6 is made to fit the working surface by the adjusting plate 4 to improve the dustproof effect. When drilling, air is taken in through the air inlet 62, and the gas enters the inner tube 63 through the first air inlet hole 631, so as to guide the coal slag and dust. At this time, the air inlet pipe 654 is tilted toward the first metering component 81 by the adjusting component 65, so as to block the coal slag and dust, so as to facilitate the coal slag and dust to enter the first metering component 81, when the drilling depth reaches 1m, the first metering component 81 is closed and the second metering component 82 is opened. At this time, the generated coal slag is weighed by the weighing equipment, and then the adjustment component 65 makes the air inlet pipe 654 tilt toward the second metering component 82, so as to guide the coal slag and dust into the second metering component 82. When the drilling depth reaches 1m again, the second metering component 82 is closed, so that the first metering component 81 and the second metering component 82 are alternately collected and measured, which is convenient for evaluating the anti-burst hole to prevent the coal seam from not penetrating or encountering a fault.
