Description

Technical Field

[0001] The present invention relates to the technical field of dust prevention and control, and in particular to a dust suppression and dust removal device for a fully mechanized mining working face. Background Art

[0002] Coal mining generates large amounts of dust, which remains suspended in the air. When these dust reaches a certain concentration or is affected by shock waves, they can cause secondary explosions, posing a serious safety hazard. Therefore, spray dust suppressors are often used during the fully mechanized mining face frame transfer process to control dust. These devices spray the air, trapping and settling the dust.

[0003] Among them, the source of dust comes from the contact position between the comprehensive mining equipment and the coal mine face. The current dust removal operations all involve spraying dust reduction at the contact position, but there are the following problems: First, the range of the spray cannot be closed at the contact position, and a large amount of dust will overflow; second, the high-speed rotation of the comprehensive mining equipment will bring up a large number of coal slag blocks of different sizes. Some loose coal slag blocks will disperse and produce dust in the process of being thrown out, and some hard coal slag blocks will also produce dust after being thrown out and contacting other hard objects. The current spray technology cannot effectively solve the above problems, resulting in poor dust suppression and dust removal effects, affecting the working environment. Summary of the Invention

DETAILED DESCRIPTION

[0039] 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 a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-4 The present invention provides a dust suppression and dust removal device for a fully mechanized mining working face, which is installed on the periphery of the fully mechanized mining equipment when in use. The device comprises:

[0041] The first pipe 100 and the second pipe 200 are radially spaced along the annular surface S (because there is a diameter difference between the excavation end and the driving end of the fully mechanized mining equipment, the radial distribution can be adapted for installation on the fully mechanized mining equipment without occupying excess space; it can also form a certain angle between the sprayed water mist and the ejected slag blocks, providing a larger contact surface and improving the dust removal effect); the first pipe 100 and the second pipe 200 have linear water outlets a. Specifically, the first pipe 100 and the second pipe 200 are provided with high-pressure water flow through external water supply equipment;

[0042] The extension lines of the linear water outlets a on the first pipe 100 and the second pipe 200 are arranged to intersect. This arrangement allows the water mists sprayed from the first pipe 100 and the second pipe 200 to intersect with each other, forming a closed surface around the fully mechanized mining equipment, reducing dust overflow and preventing cinder blocks raised by the fully mechanized mining equipment from flying outward.

[0043] The baffle plate 300 is positioned around the periphery of the space between the first and second tubes 100, 200, with gaps between the ends of the baffle plate 300 and the first and second tubes 100, 200. This arrangement ensures sufficient contact between the water mist and the dust, while also leaving sufficient space for the fully mechanized mining equipment to prevent ejected cinder blocks from becoming stuck between the device and the fully mechanized mining equipment due to insufficient space.

[0044] When this embodiment is in use, high-pressure water flow is input into the first tube 100 and the second tube 200, and planar water mist is output through the existing water outlet a thereon, and the two streams of water mist intersect with each other to form a closed surface, which not only prevents dust from overflowing, but also crushes and reduces dust on the thrown-out cinder blocks.

[0045] This embodiment forms a closed surface on the periphery of the comprehensive mining equipment through cross water mist, which not only reduces the risk of dust overflowing outwards, but also can impact the thrown out cinder blocks, assisting the cinder blocks to break up and come into contact with the water mist, reducing the risk of dust being generated again after the cinder blocks are thrown out, and improving the dust suppression and dust removal effects.

[0046] In one embodiment, see Figure 2 、 Figure 5 and Figure 6 A water diversion chamber 301 is provided in the baffle plate 300. The water diversion chamber 301 has a U-shaped structure, and one end of the water diversion chamber 301 is arranged along a first direction f1 facing the linear water outlet a on the first tube 100 or the second tube 200, and the other end is arranged in a second direction f2 at an angle to the first direction f1. Specifically, the first direction f1 and the second direction f2 are arranged in opposite directions. Preferably, the angle between the first direction f1 and the second direction f2 is 90°.

[0047] Specifically, there are multiple groups of water diversion cavities 301 evenly distributed on the baffle plate 300 , and each group of water diversion cavities 301 has two in total and corresponds to the first tube 100 and the second tube 200 respectively.

[0048] This embodiment is configured such that after the planar water mist output by the first tube 100 and the second tube 200 intersect each other, due to the high pressure, some water mist will break through the current closed surface and move toward the baffle 300. This part of the water mist also has a certain initial velocity. Most of the water mist enters from one end of the water diversion chamber 301, is guided by the water diversion chamber 301, and is output from the other end of the water diversion chamber 301. This part of the water mist has a moving direction opposite to that of the planar water mist, and can cooperate with the planar water mist generated by the first tube 100 and the second tube 200 from different directions to improve the dust reduction effect on the dust, and at the same time can improve the crushing effect on the thrown-out cinder blocks.

[0049] In one embodiment, see Figure 6-8 An impeller block 3011 is provided in the water diversion chamber 301, and the water receiving surface of the impeller block 3011 faces the direction of the water flow in the water diversion chamber 301. A rotating shaft 3012 is inserted into the impeller block 3011, and the rotating shaft 3012 is connected to the fan blade block 3013. The baffle plate 300 is provided with a guide channel communicating with the cavity 3014 for achieving airflow. The fan blade block 3013 is provided in the cavity 3014, and the cavity 3014 is communicated with the guide channel 3015.

[0050] A water filtering structure 3016 is provided in the drainage channel 3015, and the drainage channel 3015 is connected to the drainage port 3017. The drainage port 3017 is linearly arranged with the first end face s1 and the second end face s2 of the baffle plate 300. A drainage channel 3018 is provided in the baffle plate 300. One end of the drainage channel 3018 is connected to the drainage channel 3015 near the water filtering structure 3016, and the other end is connected to the conduit 3019.

[0051] This embodiment is configured such that after the planar water mist output by the first tube 100 and the second tube 200 intersect each other, due to the high pressure, some water mist will break through the current closed surface and move toward the baffle 300. This part of the water mist also has a certain initial velocity. Most of the water mist enters from one end of the water inlet chamber 301 and drives the impeller block 3011 to rotate, and drives the fan block 3013 to rotate through the rotating shaft 3012, generating a suction airflow in the cavity 3014, and the water mist that diffuses to the two end surfaces of the baffle 300 and is in full contact with the dust is attracted into the drainage channel 3015. After contacting the water filter structure 3016, this part of the water mist gathers into water droplets and is discharged outward through the drainage channel 3018 and the conduit 3019, so as to prevent the water mist from spreading outward, which not only affects the working environment of the comprehensive mining face, but also affects the health of the staff.

[0052] Preferably, see Figure 11The drainage channel 3018 is provided with staggered protrusions 30181. The protrusions 30181 can avoid the adsorption force generated in the cavity 3014 acting on the drainage channel 3018, causing the water mist to reversely enter the drainage channel 3015 from the drainage channel 3018.

[0053] Preferably, see Figure 6 The first end surface s1 and the second end surface s2 of the baffle plate 300 are provided with baffles 304. This arrangement prevents the baffles 304 from generating a strong adsorption force on the cross-mist region formed by the first tube 100 and the second tube 200, thereby reducing the formation effect of the closed surface of the mist. When the cross-mist fully contacts the slag and overflows, the mist recombined with the dust is sucked into the drainage channel 3015 and aggregated into water droplets for discharge, thus ensuring a good working environment at the fully mechanized mining face.

[0054] In addition, in order to avoid the problem that the cross water mist sprayed by the first tube 100 and the second tube 200 cannot drive the impeller block 3011 to rotate due to insufficient speed, the first tube 100 and the second tube 200 can have at least one place facing the water inlet cavity 301 and without cross water mist generation, that is, only one of the first tube 100 and the second tube 200 needs to generate water mist at this place.

[0055] In one embodiment, see Figure 6-10 The water filtering structure 3016 includes a built-in ring 30161, which has a water filtering layer 30162, and a gap connecting the drainage channel 3018 is opened on the built-in ring 30161, wherein the built-in ring 30161 has an annular channel 30163, and the annular channel 30163 is provided with through holes 30164 distributed in a circle and facing the water filtering layer 30162. Specifically, the water filtering layer 30162 adopts water filtering cotton.

[0056] This embodiment is configured such that, due to the drainage gas generated in the cavity 3014, the water mist fused with the dust at both ends of the baffle plate 300 is sucked into the drainage channel 3015. This part of the water mist acts on the water filter layer 30162, causing the water mist to gather in the shape of water droplets and fall into the drainage channel 3018 through the gap, and is discharged to the ground of the comprehensive mining face through the conduit 3019, thereby preventing the water mist from spreading outward, which not only affects the working environment of the comprehensive mining face, but also affects the health of the workers.

[0057] In one embodiment, see Figure 10 , the first tube 100 or the second tube 200 has a branch tube 400 ( Figure 9Only a schematic diagram of the connection end of the branch pipe 400 and the annular channel 30163 is shown, and the other end is connected to the first pipe 100 or the second pipe 200). A pressure regulating valve 401 is provided on the branch pipe 400, and the water outlet end of the branch pipe 400 extends into the drainage channel 3015 and is connected to the annular channel 30163.

[0058] This embodiment is configured such that, through the configuration of the branch pipe 400, part of the water flow is guided into the annular channel 30163, and the water flow is output from the through hole 30164 at a certain speed, acting on the water filter layer 30162, and can clean the water filter layer 30162 in real time, avoiding the problem of the water filter layer 30162 being blocked by dust mixed in the water mist, thereby ensuring the normal operation of the water filter layer 30162.

[0059] In one embodiment, see Figure 8 A water diversion chamber 302 is provided in the baffle plate 300, the water inlet end of the water diversion chamber 302 is connected to the water diversion chamber 301, and the water outlet end of the water diversion chamber 302 is connected to the dust reduction port 303, and the dust reduction port 303 is linearly arranged along the first end surface s1 or the second end surface s2 of the baffle plate 300.

[0060] This embodiment is configured such that part of the water mist in the water diversion chamber 301 enters the water diversion chamber 302, is guided by the water diversion chamber 302, and is output from the dust reduction port 303, so as to perform dust reduction operations on the slag blocks that fall directly from the contact between the comprehensive mining equipment and the comprehensive mining surface, as well as the slag blocks that are thrown out.

[0061] This embodiment is only provided for the baffle plate 300 distributed near the bottom of the fully mechanized mining equipment, which is used to reduce the dust of the fallen slag blocks again, thereby further improving the dust suppression and dust removal effects.

[0062] In one embodiment, see Figure 12 , the first tube 100 and the second tube 200 have arc-shaped linear water outlets b at both ends of the surface, and the arc-shaped linear water outlets b are equidistantly distributed in a circular pattern on the surface of the first tube 100 and the second tube 200. In this way, the adjacent first tube 100 and the second tube 200 can form an effective barrier surface through the equidistantly distributed arc-shaped linear water outlets b, thereby avoiding the risk of dust overflowing from the end face of the fully mechanized mining equipment;

[0063] The arc-shaped linear water outlets b on the first pipe 100 and the second pipe 200 are arranged in staggered positions. This arrangement can form a double-layer barrier on the end face of the fully mechanized mining equipment, thereby improving the dust suppression effect.

[0064] This embodiment is configured in this way. Since the planar water mist exists on the periphery of the working surface of the comprehensive mining equipment, a small amount of dust will overflow from the end surface of the comprehensive mining equipment. After high-pressure water is input into the first tube 100 and the second tube 200, part of the planar water mist is output outward through the linear water outlet a, and another part is output outward through the arc-shaped linear water outlet b. That is, interspaced water mist is formed at the end of the first tube 100 and the second tube 200 on the end surface of the comprehensive mining equipment, and dust suppression and dust reduction operations are performed on a small amount of dust overflowing from the end surface of the comprehensive mining equipment, thereby truly forming a closed surface for dust suppression and dust removal, effectively reducing dust overflow, and improving the dust suppression and dust removal effects.

[0065] In one embodiment, see Figure 14 The first ends of the first tube 100 and the second tube 200 are suspended, and the second ends are connected to one end of the telescopic member 500. The other end of the telescopic member 500 is hinged to the ring 501. The ring 501 is provided with an adjusting cylinder 502 connected to the first tube 100 and the second tube 200.

[0066] Specifically, the collar 501 may be a spliced structure of two semicircles, so that it can be assembled on the fully mechanized mining equipment at a later stage.

[0067] Specifically, the telescopic member 500 may be a cylinder.

[0068] This embodiment is configured such that the device can be fixed to the comprehensive mining equipment by the setting of the ring 501, and the radially distributed first tubes 100 and second tubes 200 generate a cross water mist closed surface, thereby achieving efficient dust suppression and reducing dust overflow; the setting of the telescopic member 500 enables each first tube 100 and second tube 200 to adjust the extension length, so that the comprehensive mining equipment can be adapted when facing different mining faces, ensuring that the mining direction of the comprehensive mining equipment will not be blocked. At this time, the first tube 100 and second tube 200 in the direction of travel are arranged in a retracted distance, and dust suppression and dust removal operations are performed around the comprehensive mining equipment and the mining face; by adjusting the setting of the cylinder 502, the angle of each first tube 100 and second tube 200 can be adjusted according to demand, so that the device can adapt to comprehensive mining equipment of different diameters, thereby improving the adaptability of the device.

[0069] In one embodiment, the surface of the blocking plate 300 has evenly distributed pointed protrusions (not shown in the figure).

[0070] This embodiment is configured such that the pointed protrusions can enhance the impact effect of the blocking plate 300 on the thrown-out cinder blocks, thereby enhancing the crushing effect on the cinder blocks.

[0071] In one embodiment, see Figure 13The first tubes 100 and the second tubes 200 are evenly distributed in a circular shape along the annular surface S, and cross-shaped water mist is formed between adjacent first tubes 100 and second tubes 200 through the linear water outlet a.

[0072] This embodiment is configured such that by distributing the first tube 100 and the second tube 200 along the circumference of the annular surface S, the comprehensive mining equipment can be completely surrounded, thereby forming a completely closed annular surface around the comprehensive mining equipment, so that the dust and slag blocks generated by the high-speed rotation of the comprehensive mining equipment can be effectively suppressed, thereby improving the overall dust suppression and dust removal effects.
