Description
Technical Field
[0001] This utility model relates to the field of mining equipment technology, specifically to a dust removal device for a mining unloading station. Background Technology
[0002] In mining operations, unloading stations are important locations for unloading and transferring ore. During the process of unloading ore from transport equipment to storage or conveying devices, a large amount of dust is generated. This dust not only seriously pollutes the working environment and endangers the health of operators, but also can easily lead to occupational diseases such as pneumoconiosis if exposed to high dust environments for a long time. Furthermore, dust may also cause safety accidents such as explosions, posing a huge threat to the safe production of mines.
[0003] However, the existing dust removal devices at mine unloading stations still have some problems in use:
[0004] Traditional dust control methods at mining unloading stations are relatively simple, typically employing basic spray dust suppression devices. These devices simply involve setting up a few nozzles near the unloading point to spray water mist to settle some of the dust. However, due to the massive amount of dust generated during ore unloading and its rapid diffusion, the effect of simple spray dust suppression is limited and cannot effectively control the spread of dust. Furthermore, it is difficult to precisely adjust the spray volume according to the actual dust generation situation, and excessive spraying may increase the moisture content of the ore, affecting subsequent processing and transportation.
[0005] Therefore, we propose a dust removal device for mining unloading stations to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide a dust removal device for a mining unloading station, in order to solve the problem that the dust removal methods for mining unloading stations mentioned in the background art are relatively simple, usually using a simple spray dust suppression device. This device simply sets up a few nozzles near the unloading point to spray water mist to settle some of the dust. However, due to the huge amount of dust generated during ore unloading and its rapid diffusion speed, the effect of simple spray dust suppression is limited and cannot effectively control the diffusion of dust. At the same time, it is difficult to accurately adjust the spray volume according to the actual dust generation situation. Excessive spraying may increase the humidity of the ore, affecting subsequent processing and transportation.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for a mining unloading station, comprising an unloading station body and a dust collection box:
[0008] A dust collection box is installed on one side of the unloading station body. A fan box is fixedly installed on the top of the dust collection box. A dust and gas pipe is connected to one side of the dust collection box. An air volume regulating valve is fixedly installed in the middle of the dust and gas pipe. A dust discharge port is provided at the bottom of the dust collection box. A clean air outlet is connected to one side of the fan box. A dust suction hood is connected to the top of the dust and gas pipe. A water tank is fixedly installed on one side of the unloading station body. A water pump is bolted to the top of the water tank. A connecting water pipe is connected to the middle of the water pump. A water supply pipe is connected to the top of the connecting water pipe. The water supply pipe is distributed in a ring around the outside of the dust suction hood. Several mist nozzles are connected to the inside of the water supply pipe. Four sets of fixing frames are welded to the outer surface of the dust suction hood, and the water supply pipe passes through the middle of the fixing frames.
[0009] Using the above technical solution, the fan box extracts dust-laden gas generated by the unloading station through the dust gas duct and the dust collection hood. The air volume regulating valve on the dust gas duct can adjust the air volume. The dust-laden gas enters the dust collection box for treatment, and the dust is discharged from the bottom ash discharge port. The purified gas is discharged from the clean gas outlet. The water pump above the water tank delivers water through the connecting water pipe and the water supply pipe to the water supply pipe distributed in a ring on the outside of the dust collection hood. Then, it is sprayed out by several mist nozzles on the inside to spray and suppress the dust in the dust collection hood. The fixing frame is used to stabilize the water supply pipe, so as to achieve efficient dust removal and improve the environment of the unloading station.
[0010] Preferably, a dust suppressant storage tank is fixedly installed on the upper surface of the water tank, and the outlet of the dust suppressant storage tank is connected to the water tank. An inlet is provided on one side of the dust suppressant storage tank.
[0011] Using the above technical solution, the dust suppressant storage tank is connected to the water tank through the outlet, which can quantitatively input the stored dust suppressant into the water tank. The inlet is used to add dust suppressant to ensure that the dust suppressant storage in the tank is sufficient. The water in the water tank is mixed with the dust suppressant and then pumped out by the mist nozzle to enhance the adsorption and sedimentation effect of the water mist on the dust, thereby improving the dust removal efficiency of the dust removal device at the mine unloading station.
[0012] Preferably, a piston rod is provided in the middle of the dust suppressant storage tank, an electric push rod is bolted to the upper end of the water tank, a fixing plate is fixed to the extended end of the electric push rod, and the top end of the piston rod is fixedly connected to one end of the fixing plate.
[0013] Using the above technical solution, when the electric push rod is working, its extended end pushes the fixed plate, which in turn drives the piston rod connected to it to move up and down in the middle of the dust suppressant storage tank. The movement of the piston rod controls the opening and closing degree of the dust suppressant storage tank outlet, thereby achieving precise adjustment of the flow rate of the dust suppressant injected into the water tank. This ensures that the dust suppressant and water are mixed in a suitable ratio under different dust generation levels, effectively improving the dust removal effect.
[0014] Preferably, the water tank has a transmission chamber at its inner bottom and a stirring chamber in its middle. A motor is bolted to the bottom side of the water tank. A drive shaft is rotatably connected to the output end of the motor, which is located in the middle of the transmission chamber. A first bevel tooth is fixed on the outer surface of the drive shaft, and a second bevel tooth meshes with the outer surface of the first bevel tooth.
[0015] Using the above technical solution, after the motor starts, its output end drives the drive shaft to rotate in the transmission cavity. The first bevel tooth on the drive shaft rotates accordingly and meshes with the second bevel tooth for transmission. In this way, the power of the motor can be transmitted to the stirring device through the gear transmission, so as to achieve the stirring and mixing of the dust suppressant and water in the water tank, so that the two are evenly mixed and the dust suppression effect of the mixture is improved.
[0016] Preferably, a stirring shaft is fixed to the upper end face of the second conical tooth, and the top end of the stirring shaft is rotatably connected to the inner top of the stirring chamber. Three sets of stirring blades are fixed to the outer surface of the stirring shaft.
[0017] Using the above technical solution, when the second bevel tooth rotates, it drives the fixed stirring shaft to rotate synchronously in the stirring chamber. The three sets of stirring blades on the outer surface of the stirring shaft rotate accordingly. Through the rotation of the stirring blades, the mixture of dust suppressant and water in the water tank stirring chamber is fully stirred, ensuring that the dust suppressant is evenly dispersed, improving the dust reduction effect, and ensuring the stable and efficient operation of the dust removal device.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. The fan box extracts dust-laden gas generated by the unloading station through dust and gas pipes and dust collection hoods. The air volume regulating valve on the dust and gas pipes can adjust the air volume. The dust-laden gas enters the dust collection box for treatment, and the dust is discharged from the bottom ash discharge port. The purified gas is discharged from the clean gas outlet. The water pump above the water tank delivers water through connecting water pipes and water supply pipes to the water supply pipes distributed in a ring on the outside of the dust collection hood. Then, it is sprayed out by several mist nozzles on the inside to spray and suppress the dust in the dust collection hood. The fixing frame is used to stabilize the water supply pipes to achieve efficient dust removal and improve the environment of the unloading station.
[0020] 2. The dust suppressant storage tank is installed on the upper surface of the water tank, with its outlet connected to the water tank. An inlet is located on one side for replenishing the dust suppressant. The piston rod in the middle of the dust suppressant storage tank is connected to a fixed plate fixed to the protruding end of an electric push rod bolted to the upper surface of the water tank. During operation, the electric push rod extends and retracts, driving the fixed plate to move, thereby controlling the piston rod to move up and down. This adjusts the opening and closing degree of the dust suppressant storage tank outlet, precisely controlling the flow rate of the dust suppressant into the water tank. This allows the dust suppressant to be mixed with water in a suitable ratio according to the actual dust generation, enhancing the adsorption and sedimentation effect of the water mist on the dust, improving dust removal efficiency, and effectively improving the dust pollution situation at the mining unloading station.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Please see Figures 1-5 This utility model provides a technical solution: a dust removal device for a mining unloading station, comprising an unloading station body 1 and a dust collection box 2; a dust collection box 2 is provided on one side of the unloading station body 1, a fan box 3 is fixedly installed on the top of the dust collection box 2, a dust gas pipeline 4 is connected to one side of the dust collection box 2, an air volume regulating valve 5 is fixedly installed in the middle of the dust gas pipeline 4, a dust discharge port 6 is provided at the bottom of the dust collection box 2, a clean air outlet 7 is connected to one side of the fan box 3, and a clean air outlet 7 is connected to the top of the dust gas pipeline 4. A dust collection hood 8 is connected to a water tank 9 fixedly installed on one side of the unloading station body 1. A water pump 10 is bolted to the top of the water tank 9. A connecting water pipe 11 is connected to the middle of the water pump 10. A water supply pipe 12 is connected to the top of the connecting water pipe 11. The water supply pipe 12 is distributed in a ring on the outside of the dust collection hood 8. Several mist nozzles 13 are connected to the inside of the water supply pipe 12. Four sets of fixing frames 14 are welded to the outer surface of the dust collection hood 8, and the water supply pipe 12 passes through the middle of the fixing frame 14.
[0029] After the fan box 3 is started, it generates suction, which draws the dust-laden gas generated by the unloading station body 1 through the dust and gas pipe 4 and into the dust collection hood 8. The air volume regulating valve 5 can adjust the dust and gas flow rate as needed. The dust-laden gas enters the dust collection box 2 for treatment. The dust is discharged from the bottom ash discharge port 6, and the purified gas flows out from the clean gas outlet 7. At the same time, the water pump 10 above the water tank 9 draws water and delivers it through the connecting water pipe 11 to the water supply pipe 12 distributed in a ring on the outside of the dust collection hood 8. The water is then sprayed out by the mist nozzle 13 on the inside to form a water mist, which reduces the dust in the dust collection hood 8. The fixing frame 14 is used to stabilize the water supply pipe 12. Thus, by combining dust collection and spray dust reduction, the dust concentration of the unloading station can be effectively reduced, the working environment can be improved, and the health of the staff and the normal operation of the equipment can be protected.
[0030] A dust suppressant storage tank 15 is fixedly installed on the upper surface of the water tank 9, and the outlet of the dust suppressant storage tank 15 is connected to the water tank 9. A feed inlet 16 is provided on one side of the dust suppressant storage tank 15. A piston rod 17 is provided in the middle of the dust suppressant storage tank 15. An electric push rod 18 is bolted to the upper surface of the water tank 9. A fixing plate 19 is fixed to the extended end of the electric push rod 18, and the top end of the piston rod 17 is fixedly connected to one end of the fixing plate 19.
[0031] The dust suppressant storage tank 15 is installed on the upper end of the water tank 9, and its outlet is connected to the water tank 9. A feed inlet 16 is provided on one side for replenishing the dust suppressant. The piston rod 17 in the middle of the dust suppressant storage tank 15 is connected to the fixed plate 19 fixed to the protruding end of the electric push rod 18 bolted to the upper end of the water tank 9. During operation, the electric push rod 18 extends and retracts, driving the fixed plate 19 to move, thereby controlling the piston rod 17 to move up and down, thereby adjusting the opening and closing degree of the outlet of the dust suppressant storage tank 15, accurately controlling the flow rate of the dust suppressant into the water tank 9, so that the dust suppressant can be mixed with water in a suitable ratio according to the actual dust generation, enhancing the adsorption and sedimentation effect of water mist on dust, improving dust removal efficiency, and effectively improving the dust pollution situation of the mining unloading station.
[0032] A transmission chamber 20 is provided at the bottom of the water tank 9, and a stirring chamber 21 is provided in the middle of the water tank 9. A motor 22 is bolted to the bottom side of the water tank 9. A drive shaft 23 is rotatably connected to the output end of the motor 22, which is located in the middle of the transmission chamber 20. A first bevel tooth 24 is fixed on the outer surface of the drive shaft 23, and a second bevel tooth 25 meshes with the outer surface of the first bevel tooth 24. A stirring shaft 26 is fixed to the upper end face of the second bevel tooth 25, and the top end of the stirring shaft 26 is rotatably connected to the top of the stirring chamber 21. Three sets of stirring blades 27 are fixed on the outer surface of the stirring shaft 26.
[0033] After the motor 22, which is bolted to the bottom of the water tank 9, is started, its output end drives the drive shaft 23 located in the middle of the transmission cavity 20 to rotate. The first bevel tooth 24 fixed on the outer surface of the drive shaft 23 rotates synchronously. Since the first bevel tooth 24 and the second bevel tooth 25 mesh with each other, the rotation of the first bevel tooth 24 drives the second bevel tooth 25 to rotate. The stirring shaft 26 fixed on the upper end face of the second bevel tooth 25 rotates synchronously in the stirring cavity 21. The three sets of stirring blades 27 fixed on the outer surface of the stirring shaft 26 also rotate at high speed. This can fully stir the mixture of dust suppressant and water in the stirring cavity 21 of the water tank 9, ensuring that the dust suppressant is evenly dispersed in the water. This allows the mixture to more effectively adsorb and settle dust during the spray dust suppression process, improving the dust suppression performance of the entire dust removal device and ensuring the dust removal effect of the mining unloading station.
[0034] Working principle: For this type of dust removal device in a mining unloading station, the fan box 3 generates suction when started. Through the dust-laden gas pipe 4, the dust-laden gas generated by the unloading station body 1 is drawn in through the dust collection hood 8. The airflow regulating valve 5 adjusts the dust-laden gas flow as needed. The dust-laden gas enters the dust collection box 2 for processing. Dust is discharged from the bottom ash discharge port 6, and purified gas flows out from the clean gas outlet 7. Simultaneously, the water pump 10 on the water tank 9 draws water from the tank and sends it through the connecting water pipe 11 to the water supply pipe 12, which is distributed in a ring around the outside of the dust collection hood 8. The water is then sprayed out from the inner mist nozzle 13 to form a water mist for dust suppression. The fixing frame 14 secures the water supply pipe 12. In addition, the dust suppressant storage tank 15 on the upper surface of the water tank 9 replenishes the dust suppressant through the feed inlet 16. The system is electrically powered. The push rod 18 extends and retracts, driving the fixed plate 19 to control the piston rod 17 to move up and down, adjusting the opening and closing of the outlet of the dust suppressant storage tank 15, and precisely controlling the flow rate of the dust suppressant into the water tank 9, so that it is mixed with water in a suitable proportion according to the actual dust situation. The motor 22 on the bottom side of the water tank 9 starts, and the output end drives the drive shaft 23 to rotate. The first bevel tooth 24 on the drive shaft 23 drives the second bevel tooth 25 that meshes with it to rotate, thereby driving the stirring shaft 26 and the three sets of stirring blades 27 on the outer surface to rotate at high speed in the stirring chamber 21, fully stirring the mixture of dust suppressant and water, ensuring that the dust suppressant is evenly dispersed, enhancing the adsorption and sedimentation effect of water mist on dust, comprehensively improving dust removal efficiency, and effectively improving the dust pollution situation of the mining unloading station.
