Description

Technical Field

[0001] This invention relates to the field of dust removal technology in mining, and in particular to an environmentally friendly dust removal device for mining operations. Background Technology

[0002] Mining encompasses various types of mining, including coal, metallic, non-metallic, building material, and chemical mines. In the production process, excavation and extraction, as the core production link, not only consumes the most manpower, material resources, and capital, but is also the key node with the greatest potential for controlling mining costs. The main ways to reduce excavation and extraction costs are to improve labor productivity, ensure operational quality, and strictly control material consumption; however, mining activities often face severe working environment challenges. Because operations typically take place in enclosed or semi-enclosed tunnels, processes such as blasting, drilling, and loading / unloading generate large amounts of dust, leading to increased airborne dust concentrations and seriously threatening miners' occupational health and safety. To improve the working environment, effective dust removal devices must be used to reduce airborne dust content and achieve air purification.

[0003] Currently, wet dust collection is one of the most widely used dust removal methods in underground mines. Its principle is to generate water mist through a spray system, allowing dust particles to come into full contact with the water mist, condense, and gain weight, thereby being captured and separated from the airflow by sedimentation. However, this method consumes a large amount of water resources, and the resulting wastewater requires further treatment.

[0004] Therefore, this application proposes an environmentally friendly dust removal device that can reduce water consumption and wastewater generation in wet dust removal. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing an environmentally friendly dust removal device for mining operations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An environmentally friendly dust removal device for mining operations includes a dust collection pipe vertically fixed to the top of a housing and a spiral impeller installed inside the dust collection pipe. The spiral impeller is used to separate dust from the dust-laden air entering the dust collection pipe and place it on the inner wall of the dust collection pipe. The surface of the spiral impeller has multiple spiral blades evenly distributed. The surface of the dust collection pipe is equipped with a dust suppression component that sprays water mist.

[0007] In some embodiments, the suction pipe is provided with a dust collection component for collecting dust on the inner wall of the suction pipe and allowing it to settle from the center of the suction pipe. The dust collection component includes a plurality of dust collection grooves evenly distributed on the inner wall of the suction pipe. The bottom of the dust collection grooves is connected to a dust discharge pipe through a dust conveying pipe. The dust discharge pipe and the suction pipe are coaxially arranged.

[0008] In some embodiments, the dust collection trough is formed by a connecting ring and a plurality of partitions obliquely fixed to the surface of the connecting ring, and the oblique direction of the partitions is the same as the spiral direction of the airflow. The dust conveying pipe is spiral-shaped, and the height of the dust discharge pipe is lower than the height of the dust collection trough.

[0009] In some embodiments, the dust suppression assembly includes a water storage ring fixed to the surface of the suction pipe and a plurality of spray heads connected to the water storage ring.

[0010] In some embodiments, the surface of the water storage ring is provided with a rinsing assembly for cleaning the inside of the tank. The rinsing assembly includes a rotating ring that rotates on the surface of the water storage ring and multiple rinsing heads at different angles disposed on the surface of the rotating ring. The surface of the water storage ring is provided with multiple water outlets that communicate with the rotating ring.

[0011] In some embodiments, a plurality of inclined plates are vertically fixed inside the rotating ring, and a plurality of water outlets are obliquely arranged inside the rotating ring, with the inclination angle of the inclined plates corresponding to the inclination angle of the water outlets.

[0012] In some embodiments, the inner wall of the water storage ring is provided with a flow-changing component for changing the direction of water flow. The flow-changing component includes a flow-changing ring that rotates on the inner wall of the water storage ring. The flow-changing ring is used to seal the spray head and the water outlet.

[0013] In some embodiments, the bottom of the converter ring is provided with a plurality of first through holes corresponding to the spray head, and the outer periphery of the converter ring is provided with a plurality of second through holes corresponding to the water outlet; the positions of the first through holes and the second through holes are corresponding to each other, and the positions of the spray head and the water outlet are staggered.

[0014] In some embodiments, the converter ring rotates on the inner wall of the water storage ring via a rotating assembly. The rotating assembly includes a guide groove formed on the inner wall of the converter ring and a pull rod that cooperates with the guide groove. The lower end of the pull rod slides on the inner wall of the guide groove via a guide head. The guide groove is obliquely arranged.

[0015] In some embodiments, a retaining ring is vertically slidable at the top of the suction pipe. The retaining ring is semi-circular and is used to cover the open structure at the top of the suction pipe.

[0016] Compared with the prior art, the present invention provides an environmentally friendly dust removal device for mining operations, which has the following beneficial effects.

[0017] This invention utilizes a spiral impeller and dust collection components to gather and settle airborne dust to the bottom of the chamber. The dust settling components then perform wet filtration on any remaining trace dust in the air, thereby reducing water consumption. The sprayed water mist mixes with the dust settled at the bottom of the chamber to form a sludge-like substance that can be directly discharged from the chamber. When the water in the sludge evaporates, it forms clods of soil, effectively avoiding the wastewater problems caused by existing wet filtration methods.

[0018] 2. In this invention, by setting up a flushing component, when it is necessary to clean the inner wall of the tank, water can be smoothly introduced into the rotating ring through multiple reasonably distributed water outlets. Then, the water will be violently sprayed out under high pressure through multiple flushing heads. At the same time, with the cooperation of the water outlets and the inclined plate, the rotating ring drives the flushing heads to rotate, thereby carrying out the flushing operation on the inner wall of the water tank.

[0019] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Reference Figure 1-10 An environmentally friendly dust removal device for mining operations includes a suction pipe 2 vertically fixed to the top of a housing 1 and a spiral impeller 3 installed inside the suction pipe 2. The lower end of the suction pipe 2 is located inside the housing 1 and close to the bottom of the housing 1. The upper end of the suction pipe 2 has an open structure. A turbine fan 201 is fixed to the inner wall of the suction pipe 2 to generate negative pressure at the upper end of the suction pipe 2. The spiral impeller 3 is located below the turbine fan 201 and is fixed to the inner wall of the suction pipe 2 by a mounting bracket, which is located on top of the spiral impeller 3. The spiral impeller 3 is used to separate dust from the dust-laden air entering the suction pipe 2 to the inner wall of the suction pipe 2. Multiple spiral blades are evenly distributed on the surface of the spiral impeller 3.

[0033] Understandably, by setting up the suction pipe 2, the turbine fan 201 rotates inside the suction pipe 2, creating negative pressure at the top of the suction pipe 2, thereby drawing out the dust-laden air. By setting up the spiral impeller 3, when the dust-laden air passes through the spiral impeller 3, the multiple spiral blades change the flow pattern of the fast-flowing air, causing the air to flow in a spiral shape at the bottom of the suction pipe 2. During this process, larger dust particles approach the inner wall of the suction pipe 2 and accumulate during the flow. The accumulated dust particles are more likely to fall downwards, reducing the dispersion of dust particles and causing dust to accumulate at the bottom of the housing 1. By setting the mounting bracket on top of the spiral impeller 3, the mounting bracket at the bottom of the spiral impeller 3 is not affected by the already formed spiral shape of the air, allowing the air to flow stably in a spiral shape after leaving the spiral impeller 3.

[0034] Specifically, a retaining ring 202 slides vertically at the top of the suction pipe 2. The retaining ring 202 is semi-circular and is used to cover the open structure at the top of the suction pipe 2. An exhaust chamber 203 is provided on the side of the housing 1. An exhaust port is provided on the side of the exhaust chamber 203. An air vent is provided on the side of the exhaust chamber 203 near the suction pipe 2. The air vent is angled and the angled surface faces downward. A dust filter is provided at the air vent.

[0035] Understandably, after entering the chamber 1, the air enters the exhaust chamber 203 through the vent, and then exits the chamber 1 through the exhaust port. Since the area of ​​the exhaust chamber 203 is larger than the vent, the air velocity decreases after entering the exhaust chamber 203, allowing the air to exit at a lower velocity. This prevents the high-speed airflow from blowing away dust-laden air approaching the chamber 1, thus hindering its entry into the chamber for dust removal. Furthermore, by setting up a baffle ring 202, when large-scale air purification is required, the baffle ring 202 is lowered. When the suction pipe 2 is lowered to its lowest position, its open structure is fully exposed to purify the air around the housing 1. When dust generated during mining operations needs to be removed, the baffle ring 202 is raised to its highest position to partially block the open structure of the suction pipe 2, causing the open structure to face to one side. This concentrates the negative pressure suction of the suction pipe 2 towards the mining area, improving the dust collection effect. By installing a dust filter at the vent, the air discharged from the housing 1 is filtered again, further reducing the dust content in the air discharged from the housing 1.

[0036] Specifically, the suction pipe 2 is equipped with a dust collection component 4 for collecting dust. The dust collection component 4 is located at the bottom of the suction pipe 2. The dust collection component 4 includes multiple dust collection grooves 401 evenly distributed on the inner wall of the suction pipe 2. The dust collection grooves 401 are formed by a connecting ring and multiple partitions that are obliquely fixed to the surface of the connecting ring. Both the connecting ring and the partitions are fixed to the inner wall of the suction pipe 2. The partitions are located between the connecting ring and the suction pipe 2, and the inclination direction of the partitions is the same as the spiral direction of the airflow. The bottom of the dust collection groove 401 is funnel-shaped, wider at the top and narrower at the bottom. The bottom of the dust collection groove 401 is connected to a dust collection pipe 403 through a dust conveying pipe 402. The dust collection pipe 403 is coaxial with the suction pipe 2. The dust conveying pipe 402 is spiral-shaped, and the spiral direction is the same as the spiral direction of the airflow. The bottom of the dust collection pipe 403 is an open structure, and the height of the dust collection pipe 403 is lower than the height of the dust collection groove 401.

[0037] Understandably, as air flows in a spiral motion, most of the dust accumulates on the inner wall of the suction pipe 2. If the dust were to fall directly from the inner wall of the suction pipe 2 to the bottom of the housing 1, it would spread outward from the center of the suction pipe 2. This means the dust is on the outer ring of the suction pipe 2, while the air is on the inner ring. When the air spreads within the housing 1, interference along the path will inevitably blow away the dust on the outer ring again, affecting the falling of the accumulated dust. Therefore, by setting up the dust collection component 4, the dust accumulated on the inner wall of the suction pipe 2 is collected by the dust collection tank 401. The dust enters the dust collection pipe 403 through the dust conveying pipe 402 and falls into the housing 1 from the dust collection pipe 403. At this time, the dust is located in the inner ring of the suction pipe 2, while the air is located in the outer ring of the suction pipe 2. When the air diffuses into the housing 1, it does not interfere with the dust, thus preventing the dust from being blown away by the air again. By setting the dust collection trough 401 at an angle, the obstruction when the air carries the dust into the dust collection trough 401 can be reduced, allowing the air to carry the dust smoothly through the dust collection trough 401 and the dust conveying pipe 402, preventing the dust from accumulating in the dust collection trough 401 and the dust conveying pipe 402 and causing blockage.

[0038] Specifically, a dust-suppressing component 5 is provided on the surface of the suction pipe 2. The dust-suppressing component 5 includes a water storage ring 501 fixed on the surface of the suction pipe 2 and multiple spray heads 502 connected to the water storage ring 501. The water storage ring 501 is close to the bottom of the suction pipe 2, and the multiple spray heads 502 are all located at the bottom of the water storage ring 501 and are obliquely arranged away from the suction pipe 2. A water tank 503 is provided on one side of the housing 1. The water tank 503 is located below the exhaust chamber 203. A water pump 504 is fixed on the upper surface of the housing 1. The water inlet of the water pump 504 is located at the bottom of the water tank 503. The outlet of the water pump 504 is provided with two connecting pipes, and the other ends of the two connecting pipes are respectively connected to the water storage ring 501.

[0039] Understandably, since the air diffused inside the chamber 1 inevitably contains a small amount of dust, the dust-suppressing component 5 is installed to spray water mist near the lower end of the suction pipe 2, capturing the trace dust in the air and causing it to settle to the bottom of the chamber 1. This achieves wet filtration of the air and prevents dust from being discharged from the chamber 1 with the airflow. At the same time, the sprayed water mist also falls on the dust that has already settled at the bottom of the chamber 1, wetting it and preventing the airflow at the lower end of the suction pipe 2 from stirring it up again. In operation, water is pumped from the water tank 503 by the water pump 504 and transported to the water storage ring 501. The water mist is then sprayed downwards through multiple spray nozzles 502, colliding fully with the upward-flowing air to effectively capture fine dust particles in the air, achieving wet filtration with minimal water usage. Simultaneously, the spiral impeller 3 and dust collection assembly 4 gather and settle dispersed dust particles in the air to the bottom of the housing 1. The dust settling assembly 5 then performs wet filtration on any remaining fine dust particles, further reducing water consumption. The sprayed water mist mixes with the settled dust at the bottom of the housing 1 to form a sludge-like substance, which can be directly discharged from the housing 1. As the water in the sludge evaporates, it forms clods of soil, effectively avoiding the wastewater problems associated with existing wet filtration systems.

[0040] Specifically, the surface of the water storage ring 501 is provided with a rinsing assembly 6 for cleaning the inside of the tank 1. The rinsing assembly 6 includes a rotating ring 601 that rotates on the surface of the water storage ring 501 and multiple rinsing heads 602 disposed on the surface of the rotating ring 601. The multiple rinsing heads 602 have different orientation angles and are fan-shaped. The surface of the water storage ring 501 is provided with multiple water outlets 604 that are connected to the rotating ring 601.

[0041] Understandably, due to the continuous airflow within the housing 1, some water mist and dust suspended in the air will inevitably be splashed onto the inner wall of the housing 1. Over time, this water mist and dust will gradually accumulate on the inner wall of the housing 1, forming dirt. Therefore, the flushing assembly 6 is provided so that when the inner wall of the housing 1 needs to be cleaned, water can smoothly enter the rotating ring 601 through multiple reasonably distributed water outlets 604. Then, the water will be violently sprayed out at high pressure through multiple flushing heads 602. At the same time, the rotating ring 601 will drive the flushing heads 602 to rotate, thereby carrying out the flushing operation on the inner wall of the water tank. The multiple flushing heads 602 are distributed at different angles, which can fully cover every part of the inner wall of the housing 1, ultimately achieving a good all-round flushing effect. By setting the vent at an angle, it is convenient for the flushing heads 602 to flush the dust filter at the vent, which can effectively prevent the dust filter from becoming clogged during long-term use.

[0042] Specifically, multiple inclined plates 603 are vertically fixed inside the rotating ring 601, and multiple water outlets 604 are inclined inside the rotating ring 601. The inclination angle of the inclined plates 603 corresponds to the inclination angle of the water outlets 604, and the number of inclined plates 603 is greater than the number of water outlets 604.

[0043] Understandably, by setting up the inclined plate 603, under the action of the inclined water outlet 604, the water flowing into the rotating ring 601 is sprayed obliquely onto the surface of the inclined plate 603, thereby causing the inclined plate 603 to drive the rotating ring 601 to rotate on the surface of the water storage ring 501. The automatic rotation function of the flushing head 602 can be realized without additional power drive, which simplifies the device structure and reduces energy consumption. The design that the number of inclined plates 603 is greater than the number of water outlets 604 can ensure that the water flow continuously and stably impacts the inclined plates 603 at different positions, making the rotation of the rotating ring 601 more smooth and continuous, and avoiding jamming.

[0044] Specifically, the inner wall of the water storage ring 501 is provided with a flow exchange component 7 for changing the direction of water flow. The flow exchange component 7 includes a flow exchange ring 701 that rotates on the inner wall of the water storage ring 501. The flow exchange ring 701 is used to close the spray head 502 and the water outlet 604. The bottom of the flow exchange ring 701 is provided with a plurality of first through holes 702 corresponding to the spray head 502, and the outer periphery of the flow exchange ring 701 is provided with a plurality of second through holes 703 corresponding to the water outlet 604. The positions of the first through holes 702 and the second through holes 703 are corresponding, and the positions of the spray head 502 and the water outlet 604 are staggered.

[0045] Understandably, by opening a first through hole 702 and a second through hole 703 on the surface of the converter ring 701, when dust suppression is required, the converter ring 701 rotates within the water storage ring 501, aligning the first through hole 702 with the spray head 502. Simultaneously, the converter ring 701 closes the water outlet 604, ensuring that water can only be sprayed through the spray head 502, thus completing the dust suppression operation. When cleaning is required, the second through hole 703 is rotated to align with the water outlet 604, and the converter ring 701 closes the spray head 502, allowing... Water can only be sprayed out through the rinsing head 602 to achieve the cleaning function; this design realizes the integration and convenient switching of dust suppression and cleaning functions, which significantly simplifies the operation process; in addition, the spray head 502 and the water outlet 604 are staggered, and with the corresponding first through hole 702 and second through hole 703 on the converter ring 701, it can be ensured that water will not flow out from the spray head 502 and the water outlet 604 at the same time during the function switching process, thereby ensuring the water pressure and efficiency when working with a single function and effectively avoiding the waste of water resources.

[0046] Specifically, the converter ring 701 rotates on the inner wall of the water storage ring 501 via the rotating assembly 704. The rotating assembly 704 includes a guide groove 7041 formed on the inner wall of the converter ring 701 and a pull rod 7042 that cooperates with the guide groove 7041. The pull rod 7042 slides vertically on the top of the water storage ring 501, and the lower end of the pull rod 7042 slides on the inner wall of the guide groove 7041 via a guide head. The guide groove 7041 is obliquely set. When the guide head is at the bottom of the guide groove 7041, the first through hole 702 corresponds to the spray head 502. When the guide head is at the top of the guide groove 7041, the second through hole 703 corresponds to the water outlet 604. The upper end of the pull rod 7042 slides on the top of the housing 1. The pull rod 7042 is driven to rise and fall by an electric push rod, which is fixed to the top of the housing 1.

[0047] Understandably, the electric push rod drives the pull rod 7042 to slide vertically, and under the action of the guide groove 7041, it drives the converter ring 701 to rotate, thereby changing the position of the first through hole 702 and the second through hole 703; when the pull rod 7042 drives the guide head to slide to the bottom of the guide groove 7041, the first through hole 702 corresponds to the spray head 502; when the pull rod 7042 drives the guide head to slide to the top of the guide groove 7041, the second through hole 703 corresponds to the water outlet 604. Meanwhile, the dust suppression component 5 can adjust the amount of water sprayed in a timely manner according to the actual dust concentration in the environment. By controlling the water pump 504, the water pump 504 can change the amount of water supplied to the water storage ring 501. However, if no corresponding measures are taken when the water volume decreases, it is very likely to cause the water pressure of the spray head 502 to decrease. Once the water pressure of the spray head 502 decreases, it will affect the actual spray effect and the coverage area of ​​the spray, resulting in poor spray effect and smaller coverage area. Therefore, in order to effectively avoid this situation, it is necessary to change the corresponding angle between the first through hole 702 and the spray head 502 through the commutation ring 701. For example, the first through hole 702 and the spray head 502 can be made to correspond to different ratios such as one-half or one-third. By changing the water flow cross-section size of the spray head 502 in this way, the flow pressure of the water can be effectively adjusted. When the water supply gradually decreases, the sealing area of ​​the commutation ring 701 on the spray head 502 is increased accordingly, thereby increasing the water pressure.

[0048] Specifically, the bottom of the box 1 is an open structure, and a dust discharge box 8 is hinged to the bottom of the box 1. When the dust discharge box 8 rotates to a horizontal angle, the dust discharge box 8 is located inside the box 1. The dust discharge box 8 is driven to rotate by a traction rope 801. One end of the traction rope 801 is fixed to the side of the dust discharge box 8 away from the hinge end, and the other end of the traction rope 801 is wrapped around the surface of the winding wheel 802. The winding wheel 802 rotates on the top of the box 1. The winding wheel 802 is driven to rotate by a drive motor. The traction rope 801 passes through the top of the box 1. The end of the box 1 near the traction rope 801 is arc-shaped and matches the inner wall of the box 1.

[0049] Understandably, the dust discharged from the suction pipe 2 will settle inside the dust collection box 8. Under the action of the dust settling component 5, the water flow mixes with the dust to form a sludge-like substance, which accumulates inside the dust collection box 8. When it is necessary to clean the dust inside the dust collection box 8, the traction rope 801 is released through the winding wheel 802, so that the dust collection box 8 rotates downward to an inclined angle under its own gravity, thereby allowing the sludge-like dust inside the dust collection box 8 to be discharged from one side.

[0050] In this invention, when large-scale air purification is required, the baffle ring 202 is lowered to its lowest position, fully exposing the open structure of the suction pipe 2. The turbine fan 201 rotates inside the suction pipe 2, creating negative pressure at the top of the suction pipe 2 to draw in dust-laden air. As the dust-laden air passes through the spiral impeller 3, multiple spiral blades alter the flow pattern of the rapidly moving air, causing the air to flow in a spiral shape at the bottom of the suction pipe 2. During this process, larger dust particles approach the inner wall of the suction pipe 2 and accumulate during the flow. The dust accumulated on the inner wall of the suction pipe 2 is then collected by the dust collection tank 401. The dust is collected and enters the dust collection pipe 403 through the dust conveying pipe 402, falling into the interior of the housing 1. At this time, the dust is located in the inner ring of the suction pipe 2, while the air is located in the outer ring. When the air diffuses into the housing 1, it does not interfere with the dust, thus preventing the dust from being blown away again. At the same time, the dust settling component 5 sprays water mist near the lower end of the suction pipe 2 to capture the trace dust in the air and make it settle to the bottom of the housing 1. The sprayed water mist also falls on the dust that has already settled at the bottom of the housing 1, wetting it and preventing the air flowing at the lower end of the suction pipe 2 from blowing it away again. The system lifts the dust, achieving wet filtration of the air and preventing dust from being discharged from the housing 1. The water mixes with the dust, forming a sludge-like substance that accumulates inside the dust collection box 8. When cleaning the dust collection box 8 is necessary, the traction rope 801 is released via the winding wheel 802, causing the dust collection box 8 to rotate downwards to an inclined angle under its own weight, thus allowing the sludge-like dust inside the dust collection box 8 to be discharged from one side. When cleaning the inner wall of the housing 1 is required, the second through hole 703 is rotated to align with the water outlet 604, while the commutation ring 701 closes the spray head 502, allowing water to flow through the water outlet 604 into the rotating... The rotating ring 601, under the action of the obliquely set water outlet 604, causes the water flowing into the rotating ring 601 to be sprayed obliquely onto the surface of the inclined plate 603, thereby causing the inclined plate 603 to drive the rotating ring 601 to rotate on the surface of the water storage ring 501. The rotating ring 601 will drive the flushing head 602 to rotate, thereby carrying out the flushing operation on the inner wall of the box 1. When it is necessary to remove dust generated during mining operations, the baffle ring 202 is raised to the highest position to partially block the open structure of the suction pipe 2, so that the open structure faces to one side, and the negative pressure suction of the suction pipe 2 is concentrated towards the mining area to improve the dust collection effect.
