Description

Technical Field

[0001] This invention belongs to the field of material conveying technology, specifically a material conveying protection device and conveying method for mining. Background Technology

[0002] Mining is the technology and science of extracting mineral resources from the Earth's crust and surface. In a broader sense, mining also includes the extraction of coal and oil. In essence, it is a process of selectively collecting and transporting materials. Ore extraction is generally more common in mountainous areas. For deep ores, technicians use belt conveyors to transport the extracted materials. Belt conveyors are widely used for efficient ore transportation. With their continuous and efficient conveying characteristics, belt conveyors have become indispensable equipment in mining, smelting, and processing. Mine belt conveyors typically use annular rubber belts, powered by drive rollers, and supported by idler rollers to form a trough structure, achieving continuous and stable ore transportation.

[0003] In existing technologies, when materials are poured onto belt conveyors for transport, a large amount of dust is generated. Ore dust often contains free silica, and long-term inhalation can easily cause lung disease. Furthermore, some fine mineral powders, when they reach a certain concentration, can trigger dust explosions when exposed to static electricity or sparks, with extremely strong destructive power. Secondly, as the belt conveyor transports materials, a large amount of dust adheres to its surface, greatly reducing the friction between the belt and the materials. When transporting materials uphill, the materials are prone to slipping. In addition, it is difficult to control the amount of material poured onto the belt conveyor. If too much material is poured at once, it will cause the material to overflow to both sides of the belt.

[0004] Therefore, the present invention provides a protective device for material conveying in mining and a conveying method thereof. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problem of generating large amounts of dust when materials are poured onto belt conveyors, which are prone to causing lung disease with long-term inhalation of ore dust containing free silica, and where some fine mineral powders, when at a certain concentration, can trigger dust explosions upon contact with static electricity or sparks with extremely strong destructive power, this invention proposes a protective device and method for material conveying in mining.

[0010] Preferably, both of the outer walls of the two guard plates are fixedly connected with guide plates, and both guide plates are installed at an angle.

[0011] Preferably, brackets are fixedly connected to both sides of the water tank, and a second motor is fixedly connected to the bottom of each of the two brackets.

[0015] A conveying method for a material conveying protective device used in mining, applicable to the aforementioned material conveying protective device, comprising the following steps:

[0016] S1: The material mined from the mine is put into the box, the first motor is started, and the baffle is controlled to move back and forth left and right, so that the discharge port is opened intermittently;

[0017] S2: Start the air pump to extract the dust from the box. After the dust enters the water tank, start the nozzle to spray water mist to spray and reduce the dust in the water tank.

[0018] S3: Start the second motor to control the rotation of the first and second cams, so that the nozzle and the second filter plate can vibrate continuously downward.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The material conveying protection device and conveying method for mining as described in this invention uses a first motor to control the baffle to move back and forth, causing the discharge port to open intermittently, so that the material in the box can be discharged quantitatively, avoiding the overflow of material from the conveyor caused by dumping too much material at once. The material falling from the discharge port is caught by the guide plate and slides down the inclined surface at the top of the guide plate onto the conveyor, thereby preventing the material from falling and damaging the conveyor. The dust stirred up by dumping material in the box can be extracted through the third pipe, preventing dust from flying around in the box.

[0021] 2. The material conveying protection device and conveying method for mining as described in this invention sprays water mist from nozzles to spray and suppress dust entering the water tank. A protective plate blocks the dust entering the water tank, causing the dust to concentrate near the nozzles and improving the dust spraying and settling effect. Furthermore, when dust passes through the bottom of the guide plate, the guide plate directs the dust to impact the surface of the clean water, further settling the airborne dust. The water mist sprayed from the nozzles, blocked by the protective plate, drips down along the bottom of the plate, forming a water curtain at the bottom. When dust passes through this curtain, it effectively suppresses dust.

[0022] 3. The material conveying protection device and conveying method for mining described in this invention uses a second motor to control the rotation of a first cam, which pushes the slide plate upward. Through the cooperation of the slide plate and the first spring, the nozzle can vibrate downward, thereby shaking off the mud and dirt accumulated at the nozzle and preventing the nozzle from being blocked by mud and dirt, which would affect the spraying effect. At the same time, the spraying range is increased during the up and down movement of the nozzle, which improves the dust suppression effect.

[0023] 4. The material conveying protection device and conveying method for mining described in this invention can protect the bottom of the exhaust pipe by setting a second filter plate to prevent any dust from entering the exhaust pipe. The second cam is rotated by a second motor, which, together with a second spring, makes the second filter plate vibrate downward, thereby shaking off the dust blocked at the bottom of the second filter plate and preventing the dust from clogging the second filter plate and affecting the ventilation. The dust shaken off by the second filter plate can hit the surface of clean water and settle down.

[0024] 5. The material conveying protection device and conveying method for mining described in this invention can clean the bottom of the conveyor by air jetting when the air outlet pipe sprays air upwards, so as to avoid dust adhering to the material after the conveyor conveys it, which would cause slippage between the conveyor and the material during subsequent use. At the same time as the third pipe draws air, the end of the suction pipe starts to draw air, thereby removing the dust blown down by the air outlet pipe and preventing the dust from flying above the water tank.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1 to 11As shown, the present invention provides a technical solution: a material conveying and protective device for mining, comprising a base 1, a conveyor 2 fixedly connected to the top of the base 1, two side plates 3 symmetrically fixedly connected to the top of the base 1 with the conveyor 2 as the center, a box 4 fixedly connected between the two side plates 3, the box 4 being located above the conveyor 2, a discharge port 5 opening at the bottom of the box 4, a metering component being provided at the bottom of the box 4, two partitions 6 symmetrically fixedly connected to the inner wall of the box 4, both partitions 6 being installed at an incline, a sloping plate 7 fixedly connected to the bottom of the inner wall of the box 4, a water tank 12 fixedly connected to the top of the base 1, the water tank 12 being located below the conveyor 2, an air pump 13 fixedly connected to the top of the water tank 12, an air extraction pipe 14 fixedly connected to the input end of the air pump 13, the bottom of the air extraction pipe 14 extending into the interior of the water tank 12, and the air pump 1... The output end of the 3 is fixedly connected to the air outlet pipe 15. The two sides of the water tank 12 are fixedly connected to the first pipe 16. The end of the first pipe 16 is fixedly connected to the second pipe 17. The top of the second pipe 17 is symmetrically fixedly connected to two third pipes 18. The ends of the two third pipes 18 extend into the interior of the box 4. The interior of the water tank 12 is equipped with a dust suppression component. The metering component includes a baffle 11. The baffle 11 is slidably connected to the bottom of the box 4. The bottom of the inner wall of the box 4 is fixedly connected to the first motor 8. The output end of the first motor 8 passes through the bottom of the box 4 and is fixedly connected to the crank 9. The bottom of the crank 9 is rotatably connected to the connecting shaft 10. The end of the connecting shaft 10 is rotatably connected to the baffle 11. The two side plates 3 are fixedly connected to the guide plate 42. The guide plate 42 is installed at an angle and is located between the conveyor 2 and the discharge port 5.

[0040] Through the above technical solution, the mined material is fed into the box 4. Guided by the inclined plate 7, the material falls from the discharge port 5. The first motor 8 is started, driving the crank 9 to rotate. When the crank 9 rotates to the left, it pushes the connecting shaft 10 to move to the left, causing the baffle 11 to move to the left, blocking the discharge port 5. When the crank 9 rotates to the right, it pulls the connecting shaft 10 to move to the right, causing the baffle 11 to move to the right, opening the discharge port 5. This process repeats, and with the start of the first motor 8, the discharge port 5 can be opened intermittently, allowing the material in the box 4 to be discharged quantitatively, preventing excessive material from overflowing from the conveyor 2. The air pump 13 is started, drawing air from the bottom of the extraction pipe 14. Air is discharged from the top of pipe 15. As the suction pipe 14 draws air, a negative pressure is formed in the water tank 12, which in turn causes the first pipe 16, the second pipe 17, and the third pipe 18 to begin suction. Through the suction of the third pipe 18, the dust stirred up by the dumping of materials in the box 4 can be extracted, preventing the dust from flying around in the box 4. The dust extracted by the first pipe 16, the second pipe 17, and the third pipe 18 enters the water tank 12 and is settled by the dust settling component. Furthermore, the two baffles 6 prevent the material entering the box 4 from continuously stirring up dust. The material falling from the discharge port 5 is caught by the guide plate 42 and slides down the inclined surface at the top of the guide plate 42 onto the conveyor 2, thereby preventing the material from falling and damaging the conveyor 2.

[0041] Specifically, the dust suppression assembly includes two mounting plates 19, which are symmetrically fixedly installed on the inner wall of the water tank 12. Two first sliding shafts 21 are symmetrically slidably connected through the mounting plates 19. A sliding plate 23 is fixedly connected to the bottom of both first sliding shafts 21. A nozzle 24 is fixedly connected to one side of the sliding plate 23. Limit blocks 20 are fixedly connected to the top of each of the two first sliding shafts 21. Water pumps 25 are fixedly connected to both sides of the water tank 12. A water pump pipe 26 is fixedly connected to the input end of the water pump 25. The end of the water pump pipe 26 extends to the lower interior of the water tank 12. The output of the water pump 25... A water outlet pipe 27 is fixedly connected to the end of the water tank 12. The end of the water outlet pipe 27 extends to the inside of the water tank 12 and is fixedly connected to a hose 28. The end of the hose 28 is fixedly connected to a nozzle 24. A first filter plate 29 is fixedly connected to the inner wall of the water tank 12 and above the water pumping pipe 26. A drain valve 43 is fixedly connected to the outer wall of the water tank 12 and above the first filter plate 29. Two protective plates 30 are symmetrically fixedly connected to the top of the inner wall of the water tank 12. Both protective plates 30 are installed at an angle. A guide plate 31 is fixedly connected to the outer wall of both protective plates 30. Both guide plates 31 are installed at an angle.

[0042] Through the above technical solution, clean water is filled into the water tank 12, and the water level is controlled to be below the guide plate 31. The water pump 25 is started, causing water to be drawn from the end of the water pumping pipe 26. The clean water drawn by the water pumping pipe 26 flows along the water outlet pipe 27 and the hose 28 to the nozzle 24. Water mist is sprayed out through the nozzle 24 to spray and suppress dust entering the water tank 12. The protective plate 30 blocks the dust entering the water tank 12, making the dust more concentrated near the nozzle 24, improving the dust spraying and settling effect. The air is drawn from the bottom of the air duct 14, and the dust entering the water tank 12 needs to flow upwards through the protective plate 30 and the guide plate 31. When the dust passes through the bottom of the guide plate 31, the guide plate 31 guides the dust, allowing the dust in the flow to impact the surface of the clean water, thereby further settling the dust in the air. The water mist sprayed by the nozzle 24 is blocked by the protective plate 30 and drips down along the bottom of the protective plate 30, forming a water curtain at the bottom of the protective plate 30. When the dust passes through it, it can effectively suppress the dust.

[0043] Specifically, brackets 32 are fixedly connected to both sides of the water tank 12, and second motors 33 are fixedly connected to the bottom of both brackets 32. The output end of the second motor 33 is fixedly connected to a first rotating shaft 34. The end of the first rotating shaft 34 extends into the interior of the water tank 12. A first cam 35 is fixedly connected to the outer wall of the first rotating shaft 34. The first cam 35 is used in conjunction with the slide plate 23. A first spring 22 is sleeved on the outer wall of the first sliding shaft 21. The bottom of the first spring 22 is fixedly connected to the slide plate 23, and the top of the first spring 22 is fixedly connected to the mounting plate 19.

[0044] Through the above technical solution, the second motor 33 is started, driving the first rotating shaft 34 to rotate, causing the first cam 35 to rotate. When the protruding end of the first cam 35 rotates to the top, it presses against the bottom of the slide plate 23. Under the pressure of the first cam 35, the slide plate 23 is pushed upward, causing the nozzle 24 to move upward. At the same time, the slide plate 23 presses the first spring 22. When the protruding end of the first cam 35 rotates to the bottom, it loses the pressure of the first cam 35. Under the action of the first spring 22, the slide plate 23 moves downward and vibrates, causing the nozzle 24 to vibrate downward. This facilitates the shaking off of dirt accumulated on the nozzle 24, preventing the nozzle 24 from being blocked by dirt and affecting the spraying effect. At the same time, the nozzle 24 increases the spraying range during the up and down movement, improving the dust suppression effect.

[0045] Specifically, the inner walls of both guard plates 30 are slidably connected to sliders 37, and a second filter plate 39 is fixedly connected between the two sliders 37. The bottom of the second filter plate 39 is set as a symmetrical inclined surface. The inner walls of the guard plates 30 are symmetrically fixedly connected to two second sliding shafts 36. Both second sliding shafts 36 are slidably connected to the sliders 37. The outer walls of the two second sliding shafts 36 are fitted with second springs 38. The top of the second springs 38 is fixedly connected to the guard plates 30, and the bottom of the second springs 38 is fixedly connected to the sliders 37. The end of the first rotating shaft 34 passes through the guard plate 30 and is fixedly connected to a second cam 40. The second cam 40 is used in conjunction with the second filter plate 39.

[0046] Through the above technical solution, the second filter plate 39 can protect the bottom of the exhaust pipe 14, preventing any dust from entering the exhaust pipe 14. The dust blocked by the second filter plate 39 stays at the bottom of the second filter plate 39. When the first rotating shaft 34 rotates, it drives the second cam 40 to rotate. When the protruding end of the second cam 40 rotates to the top, it presses against the bottom of the second filter plate 39. Under the pressure of the second cam 40, the second filter plate 39 is pushed upward and pressed against the second spring 38. When the protruding end of the second cam 40 rotates to the bottom, it loses the pressure of the second cam 40. Under the action of the second spring 38, the second filter plate 39 moves downward and vibrates. This facilitates the shaking off of the dust blocked at the bottom of the second filter plate 39, preventing the dust from clogging the second filter plate 39 and affecting the ventilation. Moreover, the dust shaken down by the second filter plate 39 can hit the surface of the clean water, allowing the dust to settle.

[0047] Specifically, an air intake pipe 41 is fixedly connected to the outer wall of the third pipe 18, and the air intake pipe 41 is located below the conveyor 2.

[0048] Through the above technical solution, when the air outlet pipe 15 sprays air upwards, it can clean the bottom of the conveyor 2 by air spraying, so as to prevent dust from adhering after the conveyor 2 transports materials, which would cause the conveyor to slip with the materials during subsequent use. At the same time as the third pipe 18 draws air, the end of the suction pipe 41 starts to draw air, thereby removing the dust blown down by the air outlet pipe 15 and preventing the dust from flying above the water tank 12.

[0049] Specifically, a second rotating shaft 44 is rotatably connected to the inner wall of the water tank 12 and above the first filter plate 29. Several fan blades 45 are fixedly connected to the outer wall of the second rotating shaft 44 in a ring array. Both ends of the second rotating shaft 44 pass through the water tank 12 and are fixedly connected to a second synchronous pulley 47. The outer walls of the two first rotating shafts 34 are fixedly connected to a first synchronous pulley 46. The first synchronous pulley 46 and the second synchronous pulley 47 are connected by a synchronous belt 48.

[0050] Through the above technical solution, the water sprayed down is re-accumulated at the bottom of the water tank 12. The first filter plate 29 can filter the water in the water tank 12, preventing the water pumping pipe 26 from being blocked by mud. When the first rotating shaft 34 rotates, it drives the first synchronous wheel 46 to rotate. The synchronous belt 48 can drive the second synchronous wheel 47 to rotate, causing the second rotating shaft 44 to rotate, which in turn drives several fan blades 45 to rotate. The fan blades 45 stir the water in the water tank 12, preventing mud from settling at the bottom and clogging the first filter plate 29. After a large amount of mud accumulates in the water tank 12, it can be discharged through the drain valve 43 to replace the water with clean water.

[0051] A conveying method for a material conveying protective device used in mining, applicable to the aforementioned material conveying protective device, comprising the following steps:

[0052] S1: The material mined from the mine is put into the box 4, the first motor 8 is started, and the baffle 11 is controlled to move back and forth left and right, so that the discharge port 5 is opened intermittently.

[0053] S2: Start the air pump 13 to extract the dust from the box 4. After the dust enters the water tank 12, start the nozzle 24 to spray water mist to spray the dust in the water tank 12 to reduce dust.

[0054] S3: Start the second motor 33 to control the rotation of the first cam 35 and the second cam 40, so that the nozzle 24 and the second filter plate 39 can vibrate downward continuously.

[0055] In operation, mined materials are fed into the housing 4. Guided by the inclined plate 7, the materials fall from the discharge port 5. The first motor 8 is started, driving the crank 9 to rotate. When the crank 9 rotates to the left, it pushes the connecting shaft 10 to move to the left, causing the baffle 11 to move to the left, blocking the discharge port 5. When the crank 9 rotates to the right, it pulls the connecting shaft 10 to move to the right, causing the baffle 11 to move to the right, opening the discharge port 5. This process is repeated. With the start of the first motor 8, the discharge port 5 can be opened intermittently, allowing the materials in the housing 4 to be discharged in a measured amount, preventing excessive material from overflowing from the conveyor 2. The air pump 13 is started, causing air to be drawn from the bottom of the exhaust pipe 14 and from the top of the exhaust pipe 15. As the suction pipe 14 draws air, a negative pressure is created inside the water tank 12, causing the first pipe 16, second pipe 17, and third pipe 18 to begin suction. The suction through the third pipe 18 removes dust stirred up by the dumping of materials from the box 4, preventing dust from flying everywhere. The dust drawn by the first pipe 16, second pipe 17, and third pipe 18 enters the water tank 12, and is blocked by the two baffles 6, preventing the material entering the box 4 from continuously stirring up dust. The material falling from the discharge port 5 is caught by the guide plate 42 and slides down the inclined surface at the top of the guide plate 42 onto the conveyor 2, thus preventing damage to the conveyor 2 from the falling material. Clean water is filled into the water tank 12, and the water level is controlled to be at the level of the guide plate. Below 31, the water pump 25 is activated, causing water to be drawn from the end of the water pumping pipe 26. The clean water drawn by the water pumping pipe 26 flows along the water outlet pipe 27 and the hose 28 to the nozzle 24. The water mist is sprayed out through the nozzle 24 to spray and suppress the dust entering the water tank 12. The protective plate 30 blocks the dust entering the water tank 12, making the dust more concentrated near the nozzle 24, thus improving the dust spraying and settling effect. Due to the air extraction at the bottom of the air extraction pipe 14, the dust entering the water tank 12 needs to flow upwards over the protective plate 30 and the guide plate 31. When the dust passes through the bottom of the guide plate 31, the guide plate 31 guides the dust, allowing the flowing dust to impact the surface of the clean water, thereby further settling the dust in the air. The nozzle 24 After the sprayed water mist is blocked by the protective plate 30, it drips down along the bottom of the protective plate 30, forming a water curtain at the bottom of the protective plate 30. When dust passes through it, it can effectively suppress dust. The second motor 33 is started, driving the first rotating shaft 34 to rotate, causing the first cam 35 to rotate. When the protruding end of the first cam 35 rotates to the top, it presses against the bottom of the slide plate 23. Under the pressure of the first cam 35, the slide plate 23 is pushed upward, causing the nozzle 24 to move upward. As the slide plate 23 moves upward, it presses against the first spring 22. When the protruding end of the first cam 35 rotates to the bottom, it loses the pressure of the first cam 35. Under the action of the first spring 22, the slide plate 23 moves downward and vibrates, thereby shaking off the dirt and grime that has accumulated on the nozzle 24.To prevent the nozzle 24 from being clogged by dirt and affecting the spraying effect, and to increase the spraying range and improve the dust suppression effect during the up-and-down movement of the nozzle 24, the second filter plate 39 protects the bottom of the exhaust pipe 14, preventing any dust from entering the exhaust pipe 14. The dust blocked by the second filter plate 39 stays at the bottom of the second filter plate 39. When the first rotating shaft 34 rotates, it drives the second cam 40 to rotate. When the protruding end of the second cam 40 rotates to the top, it presses against the bottom of the second filter plate 39. Under the pressure of the second cam 40, the second filter plate 39 is pushed upward, pressing the second spring 38. When the protruding end of the second cam 40 rotates to the bottom, it loses the pressure of the second cam 40. Under the action of the second spring 38, the second filter plate 39 moves downward and vibrates, thus shaking off the dust blocked at the bottom of the second filter plate 39, preventing dust from clogging the second filter plate 39 and affecting the ventilation. The dust shaken off by the second filter plate 39 can also impact the clean water. On the surface of the liquid, dust settles. When the air outlet pipe 15 sprays air upwards, it can clean the bottom of the conveyor 2, preventing dust from adhering to the conveyor 2 after conveying materials, which would cause slippage with the materials during subsequent use. While the third pipe 18 is drawing air, the end of the suction pipe 41 also starts to draw air, thereby removing the dust blown down by the air outlet pipe 15 and preventing dust from flying above the water tank 12. The water sprayed down accumulates again at the bottom of the water tank 12. The first filter plate 29 can filter the water in the water tank 12, preventing the water pumping pipe 26 from being blocked by mud. When the first rotating shaft 34 rotates, it drives the first synchronous wheel 46 to rotate. The synchronous belt 48 drives the second synchronous wheel 47 to rotate, causing the second rotating shaft 44 to rotate, which in turn drives several fan blades 45 to rotate. The fan blades 45 stir the water in the water tank 12, preventing mud from settling at the bottom and clogging the first filter plate 29. After a lot of mud accumulates in the water tank 12, it can be discharged through the drain valve 43 and clean water can be replaced. ,
