The mining dust removal device also includes: a barrier part which is movably arranged in the connecting wind tube, and the barrier part has a blocking state and an open state. When the barrier part is in the blocking state, the first wind tube and the second wind tube are separated from each other; when the barrier part is in the open state, the first wind tube and the second wind tube are connected to each other.

[0010] Further, the first connecting structure includes: a frame, which is arranged at one end of the connecting wind tube away from the second wind tube, and the frame extends along the axis direction of the connecting wind tube; a winding shaft, which extends along the length direction of the frame, and the winding shaft is rotatably arranged on the frame; a winding part, which is wound on the winding shaft, and the inner end of the winding part is fixedly arranged on the winding shaft;

[0011] Among them, the winding part has a winding state and an unfolding state.

At this time, the air inlet, the first air duct, the second air duct and the air outlet are in a fully connected state to form a complete airflow channel. The first blowing component is started to generate airflow, and the high-concentration dust in the mine is sucked in from the air inlet, transmitted through the first air duct, through the second air duct, and finally the dust-containing air is discharged out of the mine through the air outlet to achieve efficient dust removal; when the dust concentration in the mine is reduced to below a certain threshold, there is no need for dust removal, and the air circulation function is turned on instead. At this time, the wind tube component is switched to the second state, and the first connecting structure is switched from the first closed state to the first open state, the connection between the first air duct and the second air duct is cut off, and the end of the first air duct away from the air inlet is connected to the external space of the wind tube component, and the first blowing component continues to operate to inhale airflow from the air inlet, but the inhaled airflow is no longer transmitted through the second air duct, but is directly blown out from the first connecting structure in the first open state to the external space of the wind tube component, thereby promoting the circulation of air in the mine.

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely 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. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0043] like Figures 1 to 3As shown, the present invention provides a mining dust removal device, which includes a wind tube component 10 and a first blowing component 20, the wind tube component 10 has an air inlet 1101, a first air duct 1102, a second air duct 1302 and an air outlet 1301 which are arranged in sequence, and a first connecting structure 111 is arranged at one end of the first air duct 1102 away from the air inlet 1101, and the first connecting structure 111 has a first open state and a first closed state; when the first connecting structure 111 is in the first closed state, the first air duct 1102 and the second air duct 1302 are connected to each other, and when the first connecting structure 111 is in the first open state, one end of the first air duct 1102 away from the air inlet 1101 is connected to the external space of the wind tube component 10; the first blowing component 20 is arranged in the air inlet 1101, and the first blowing component 20 is used to blow air to the wind tube component 10 in the direction from the air inlet 1101 to the air outlet 1301.

[0044] Among them, the air cylinder component 10 has a first state and a second state. When the air cylinder component 10 is in the first state, the air inlet 1101, the first air duct 1102, the second air duct 1302 and the air outlet 1301 are connected in sequence; when the air cylinder component 10 is in the second state, the first air duct 1102 and the second air duct 1302 are separated, and the first connecting structure 111 is in the first open state.

[0045] By applying the technical solution of the present invention, through switching the working state of the wind tube component 10, a set of mining dust removal equipment can be used to achieve the dual functions of discharging dust outside the mine when the dust concentration in the mine is high; and promoting the circulation of air in the mine when the dust concentration is low, thereby improving the flexibility of environmental control in the mine.

[0046] Specifically, one end of the device where the air inlet 1101 is located, the first air duct 1102, the first connecting structure 111 and the second air duct 1302 are all arranged in the mine, and the end where the air outlet 1301 is located is arranged outside the mine. When dust removal is required in an environment with high dust concentration, the wind tube component 10 is in the first state. At this time, the air inlet 1101, the first air duct 1102, the second air duct 1302 and the air outlet 1301 are in a fully connected state to form a complete air flow channel. The first blowing component 20 is started to generate airflow, and the high-concentration dust in the mine is sucked in from the air inlet 1101, transmitted through the first air duct 1102, through the second air duct 1302, and finally discharged out of the mine through the air outlet 1301 to achieve efficient dust removal; when the dust concentration in the mine drops below a certain threshold, there is no need to remove dust, and the air circulation is turned on instead. Ring function, at this time, the air cylinder component 10 is switched to the second state, the first connecting structure 111 is switched from the first closed state to the first open state, the connection between the first air duct 1102 and the second air duct 1302 is cut off, and the end of the first air duct 1102 away from the air inlet 1101 is connected with the external space of the air cylinder component 10, and the first blowing component 20 continues to operate to inhale air from the air inlet 1101, but the inhaled air is no longer transmitted through the second air duct 1302, but is directly blown out from the first connecting structure 111 in the first open state to the external space of the air cylinder component 10, that is, the mine, thereby promoting the circulation of air in the mine.

[0047] The technical solution of the present invention solves the problem in the prior art that the mining dust removal system and the circulation system operate independently, resulting in redundant equipment, large space occupation and high energy consumption. This solution only uses one set of integrated system equipment to simultaneously solve the needs of dust removal and air circulation, reducing the space requirements of the equipment, reducing costs, and improving the convenience of operation.

[0048] Further, a second connecting structure 131 is provided at one end of the second air duct 1302 away from the air outlet 1301, and the second connecting structure 131 has a second open state and a second closed state, and the second connecting structure 131 is arranged in the mine. When the second connecting structure 131 is in the second closed state, when the first connecting structure 111 is in the first closed state, the ends of the first air duct 1102 and the second air duct 1302 close to each other are connected to each other; when the second connecting structure 131 is in the second open state, the end of the second air duct 1302 away from the air outlet 1301 is connected to the external space of the wind tube component 10.

[0049] The mining dust removal device further includes a second blowing component 30, which is disposed in the air outlet 1301 and is used to blow air toward the wind tube component 10 along the air inlet 1101 and the air outlet 1301. When the mining dust removal device is in the second state, the second blowing component 30 stops working. At this time, fresh air outside the mine can also flow into the mine through the air outlet 1301 and the second air duct 1302, further improving the air circulation performance in the mine.

[0050] The mining dust removal device also has a third state. When the wind tube component 10 is in the third state, the first blowing component 20 and the second blowing component 30 are in working state at the same time, the first air duct 1102 and the second air duct 1302 are separated, the first connecting structure 111 is in the first open state, and the second connecting structure 131 is in the second open state.

[0051] In the embodiment of the present scheme, when the mining dust removal device is in the first state, the first blowing component 20 and the second blowing component 30 work simultaneously, the first blowing component 20 absorbs high-concentration dust into the air cylinder component 10, and the second blowing component 30 can assist in blowing the dust in the air cylinder component 10 out of the air outlet 1301, so that the high-concentration dust is more efficiently discharged from the mine, effectively improving the dust removal efficiency. When the mining dust removal device is in the first state, the simultaneous operation of the first blowing component 20 and the second blowing component 30 can significantly enhance the dust removal efficiency.

[0052] When the mining dust removal device is in the second state, the dust concentration in the mine is low and dust removal is not needed. The mining dust removal device switches to the air circulation function. At this time, the first air duct 1102 and the second air duct 1302 are separated, and the wind blown into the first air duct 1102 by the first blowing component 20 is blown to the surroundings through the first connecting structure 111 in the first open state, thereby realizing air flow in the mine.

[0053] In the embodiment of the present scheme, when the mining dust removal device is in the third state, the circulation function and the dust removal function can be realized simultaneously.

[0054] like Figure 2 As shown, further, the wind tube component 10 includes a first wind tube 11, a connecting wind tube 12 and a second wind tube 13 which are coaxially arranged in sequence, wherein the first wind tube 11 has an air inlet 1101 and a first air duct 1102, and the second wind tube 13 has an air outlet 1301 and a second air duct 1302; the mining dust removal device also includes a blocking portion 40, which is movably arranged in the connecting wind tube 12, and the blocking portion 40 has a blocking state and an open state, when the blocking portion 40 is in the blocking state, the first wind tube 11 and the second wind tube 13 are separated from each other; when the blocking portion 40 is in the open state, the first wind tube 11 and the second wind tube 13 are connected to each other.

[0055] In the embodiment of the present scheme, when the mining dust removal device is in different working states, the state of the barrier part 40 is also different. When the mining dust removal device is in the first state for dust removal, the barrier part 40 is in an open state, so that the interior of the wind tube component 10 is connected, and the first wind tube 11, the connecting wind tube 12 and the second wind tube 13 form a directly connected channel, and the air flow can flow from the air inlet 1101 to the air outlet 1301 in the wind tube component 10 to achieve the dust removal function; when the mining dust removal device is in the second state and the third state, the barrier part 40 is in a blocking state, separating the first air duct 1102 and the second air duct 1302, so that the air sucked into the first wind tube 11 by the first blowing component 20 will be blown out from the first connecting structure 111 in the first open state, and the air in the first wind tube 11 directly acts on the barrier part 40 and spreads to the surroundings, forming a circulation and airflow guide within a certain range, thereby enhancing the circulation performance of the air in the mine.

[0056] like Figures 1 to 3 As shown, further, the first connecting structure 111 includes a skeleton 1111, a winding shaft 1112 and a winding portion 1113, the skeleton 1111 is arranged at one end of the connecting wind tube 12 away from the second wind tube 13, and the skeleton 1111 extends along the axial direction of the connecting wind tube 12; the winding shaft 1112 extends along the length direction of the skeleton 1111, and the winding shaft 1112 is rotatably arranged on the skeleton 1111; the winding portion 1113 is wound on the winding shaft 1112, and the inner end of the winding portion 1113 is fixedly arranged on the winding shaft 1112. Specifically, the device also includes a motor component, which is arranged on the skeleton 1111 and is drivingly connected to the winding shaft 1112, so that the winding shaft 1112 drives the winding portion 1113 to realize the function of winding.

[0057] Among them, the winding portion 1113 has a winding state and an unfolding state. When the winding portion 1113 is in the winding state, the outer end of the winding portion 1113 is wound around the winding shaft 1112, and the first connecting structure 111 is in a first open state; when the winding portion 1113 is in the unfolding state, the outer end of the winding portion 1113 rotates around the circumference of the connecting wind tube 12, and the end of the winding portion 1113 close to the connecting wind tube 12 is sealed and connected to the connecting wind tube 12, and the first connecting structure 111 is in a first closed state.

[0058] It can be understood that the circumference of the skeleton 1111, the circumference of the first wind tube 11 and the circumference of the connecting wind tube 12 are the same. The winding portion 1113 is movably arranged on the skeleton 1111. Specifically, when the first connecting structure 111 is switched from the first open state to the first closed state, the winding portion 1113 needs to be switched from the winding state to the unfolded state, the winding shaft 1112 rotates, and the winding portion 1113 gradually unfolds along the circumferential direction of the skeleton 1111 until it is fully unfolded. At this time, the first wind tube 11 and the connecting wind tube 12 are sealed and connected through the first connecting structure 111 in the first closed state to form a closed channel. When the winding portion 1113 is switched from the unfolded state to the wound state, the winding shaft 1112 rotates in the opposite direction, and the winding portion 1113 retracts from the unfolded state to the wound state and is rewound on the winding shaft 1112. The first connecting structure 111 can realize the switching between two working states through a simple structure without the need for additional components or mechanisms, thus simplifying the structure and increasing the reliability of the mining dust removal device.

[0059] In the embodiment of the present solution, the first connecting structure 111 further includes a guide groove 1114 and a guide portion 1115. The guide groove 1114 is provided on the frame 1111, and the extension direction of the guide groove 1114 is the same as the winding direction of the winding portion 1113. The guide portion 1115 is provided on the winding portion 1113, and the guide portion 1115 is movably provided in the guide groove 1114. The winding portion 1113 cooperates with the frame 1111 through the guide groove 1114 and the guide portion 1115, so as to improve the stability of the winding portion 1113 in the switching process between the winding state and the unfolding state.

[0060] In the embodiment of the present scheme, the skeleton 1111 includes a first guide ring, a second guide ring and a plurality of connecting rods. The first guide ring is fixedly connected to the first air cylinder 11, the second guide ring is fixedly connected to the connecting air cylinder 12, a plurality of connecting rods are arranged between the first fixing ring and the second fixing ring along the circumferential intervals of the first fixing ring and the second fixing ring, guide grooves 1114 are respectively arranged on the sides of the first guide ring and the second guide ring close to each other, one end of the winding shaft 1112 is rotatably arranged on the first fixing ring, and the second end of the winding shaft 1112 is rotatably arranged on the second fixing ring.

[0061] In some embodiments of the present solution, the guide portion 1115 includes a plurality of guide balls spaced apart along the extension direction of the winding portion 1113. Such a configuration can improve the smoothness of the movement of the winding portion 1113.

[0062] Furthermore, the first connecting structure 111 and the second connecting structure 131 have the same structure, and the first connecting structure 111 and the second connecting structure 131 are symmetrically arranged at two ends of the connecting wind tube 12. Such an arrangement can improve the convenience during processing and assembly.

[0063] As 2 to Figure 5 As shown, further, the barrier 40 includes a connecting shaft 41 and an arc plate 42, the connecting shaft 41 is coaxial with the connecting wind tube 12, and the connecting shaft 41 is rotatably arranged in the connecting wind tube 12; there are multiple arc plates 42, and the multiple arc plates 42 are stacked and distributed along the axial direction of the connecting shaft 41, the arc plates 42 are coaxial with the connecting wind tube 12, and a linkage structure 50 is arranged between two adjacent arc plates 42; the arc plate 42 at one end is fixedly connected to the connecting wind tube 12, and the remaining arc plates 42 are rotatably arranged on the connecting shaft 41, and the connecting shaft 41 is drivingly connected to the arc plate 42 at the other end, and the two adjacent arc plates 42 are sequentially unfolded or folded through the linkage structure 50, so that the barrier 40 switches between the blocking state and the open state. In this way, the barrier 40 can conveniently switch between the blocking state and the open state through the dynamic changes of the multiple arc plates 42 and their linkage structure 50 on the connecting shaft 41.

[0064] Specifically, when the barrier 40 is in the open state, all the arc plates 42 overlap and stack together; when the barrier 40 needs to be switched to the barrier state, the connecting shaft 41 rotates, driving the arc plate 42 fixedly connected thereto to rotate, and when the arc plate 42 is gradually unfolded, through the action of the linkage structure 50, each subsequent arc plate 42 is unfolded in sequence, until all the arc plates 42 are fully unfolded to form a complete barrier 40. When the barrier 40 is in the barrier state, in the direction perpendicular to the reference plane, the contours of the projections of the multiple arc plates 42 on the reference plane form a circle, and the reference plane is a plane perpendicular to the axial direction of the air duct 12. When the barrier 40 needs to be switched from the barrier state to the open state, the connecting shaft 41 rotates in the opposite direction, driving the arc plate 42 fixedly connected thereto to rotate in the opposite direction, and the linkage structure 50 acts accordingly, so that each subsequent arc plate 42 is folded in sequence, until all the arc plates 42 are fully folded and stacked together.

[0065] like Figure 3As shown, further, the mining dust removal device also includes a driving unit 60, which is driven and connected to the outer end of the winding part 1113 and the connecting shaft 41 respectively, so that when the barrier part 40 is in the blocking state, the winding part 1113 is in the unfolded state; when the barrier part 40 is in the open state, the winding part 1113 is in the winding state. The above-mentioned setting enables the first connecting structure 111 and the barrier part 40 to act synchronously. Under the action of the driving unit 60, when the barrier part 40 switches from the blocking state to the open state, the winding part 1113 is also synchronously wound, until when the barrier part 40 is fully opened, the first connecting structure 111 also just reaches the first closed state at the same time, and the mining dust removal device switches to the first state to carry out the next step of work. The coordinated work of the first connecting structure 111 and the barrier part 40 is realized by a driving device, which simplifies the structure of the mining dust removal device and improves the operating efficiency of the mining dust removal device.

[0066] Furthermore, the driving unit 60 includes a driving motor 61, a connecting rod 62 and an output shaft 63. The driving motor 61 has an output shaft 63, and the output shaft 63 and the connecting shaft 41 are coaxially arranged to connect the wind tube 12, and the output shaft 63 is drivingly connected to the connecting shaft 41; the connecting rod 62 is perpendicular to the output shaft 63, one end of the connecting rod 62 is fixedly connected to the output shaft 63, and the other end of the connecting rod 62 is fixedly connected to the outer end of the winding unit 1113. Through the connecting rod 62 and the output shaft 63, the driving motor 61 can realize synchronous driving control of the winding unit 1113 and the connecting shaft 41, realizes simplified control, and improves the convenience of operation.

[0067] It can be understood that in the embodiment of the present solution, two connecting rods 62 are provided, and the two connecting rods 62 are respectively connected to the winding portion 1113 of the first connecting structure 111 and the winding portion 1113 of the second connecting structure 131. When the first connecting structure 111 is in the first open state, the second connecting structure 131 is in the second open state, and when the first connecting structure is in the second open state, the second connecting structure is in the second open state.

[0068] like Figures 3 to 5 As shown, further, the linkage structure 50 includes a slide groove 51 and a slider 52. The slide groove 51 is arranged on one side surface of the arc plate 42, and the extension direction of the slide groove 51 is the same as the rotation direction of the arc plate 42; the slider 52 is arranged on the other side surface of the arc plate 42, and the slider 52 slides with the slide groove 51 on the rear arc plate 42.

[0069] Specifically, the slide groove 51 is an arc-shaped structure, and the extension direction of the slide groove 51 is the same as the extension direction of the side of the arc plate 42 away from the connecting shaft 41. The two ends of the slide groove 51 are respectively close to the two sides of the arc plate 42 and are both blocked. The slider 52 is set at the position close to the side of the arc plate 42, so that the length of the slide groove 51 can be increased as much as possible, and the overlap area of ​​two adjacent arc plates 42 can be reduced. The coordinated use of the slide groove 51 and the slider 52 ensures that the arc plate 42 can move smoothly along the predetermined track during the unfolding and folding process, avoids jamming or misalignment between components, and improves the stability and reliability of the overall action of the baffle 40.

[0070] like Figure 2 As shown, further, when the plurality of arc-shaped plates 42 are in the unfolded state, there is a gap between the two arc-shaped plates 42 at the two ends, and the barrier 40 further includes a blocking portion 43, which is arranged in the connecting air duct 12, and the blocking portion 43 is used to block the gap. The setting of the blocking portion 43 effectively prevents the airflow from leaking from the gap between the arc-shaped plates 42 when the barrier 40 is in the closed state, so that the barrier 40 can be in a completely closed state, thereby improving the air tightness of the barrier 40.

[0071] Furthermore, the device also includes a dust concentration detection unit and a control system. The dust concentration detection unit is used to detect the dust concentration. The dust concentration detection unit, the drive motor 61, the first blowing component 20 and the second blowing component 30 are electrically connected to the control system respectively.

[0072] When the dust concentration detected by the dust detection unit is higher than the first threshold value, the control system controls the first blowing component 20 and the second blowing component 30 to be in a working state; the driving motor 61 drives the winding part 1113 to be in an unfolded state, and the barrier part 40 to be in an open state; this device only performs dust removal work.

[0073] When the dust concentration detected by the dust detection unit is higher than the second threshold and lower than the first threshold, wherein the first threshold is greater than the second threshold, the control system controls the first blowing component 20 to be in a working state and the second blowing component 30 to be in a working state; the driving motor 61 drives the winding part 1113 to be in a winding state, and the blocking part 40 to be in a blocking state; the device performs dust removal and circulation operations simultaneously.

[0074] When the dust concentration detected by the dust detection unit is lower than the second threshold value, the control system controls the first blowing component 20 to be in a working state and the second blowing component 30 to be in a stationary state; the driving motor 61 drives the winding part 1113 to be in a winding state, and the blocking part 40 to be in a blocking state; this device only performs a cyclic operation.
