Description

Technical Field

[0001] This utility model belongs to the technical field of dust suppression devices, and in particular relates to a dust suppression device for coal mining. Background Technology

[0002] The main use of charcoal is as fuel. Coal mines are reasonable spaces excavated by humans when mining geological layers rich in coal. They usually include roadways, shafts, and mining faces. In the underground working environment of coal mines, dust suppression spraying is an essential part of underground production. Dust suppression spraying devices can remove dust from the mining environment, improve visibility during construction, and reduce the harm of dust to the physical and mental health of workers.

[0003] Existing dust suppression devices for coal mines typically include the following structure: a frame, with a motor-driven turntable mounted on the upper surface of the frame. The motor drives the turntable to rotate the mist cannon cylinder left and right. A mounting frame is mounted on the upper surface of the turntable, and a rotating rod is installed inside the mounting frame. The rotating rod is fixedly connected to the mist cannon cylinder, and the rotating rod is driven by the motor to adjust the angle of the mist cannon cylinder's vertical rotation. A fan is installed inside the mist cannon cylinder to blow the atomized water vapor further, achieving dust suppression over a wider area. An annular pipe is fixedly mounted on one surface of the mist cannon cylinder, and multiple atomizing nozzles are fixedly connected to the inner circumference of the annular pipe by bolts. The atomizing nozzles spray water vapor. A water tank is fixedly mounted inside the frame, and a water pump is fixedly connected to the upper surface of the frame by bolts. A water supply pipe is fixedly connected between the water pump and the annular pipe, and a water suction pipe is fixedly connected between the water pump and the water tank. Locking casters are installed on the bottom surface of the frame for moving the equipment.

[0004] However, the above-mentioned dust suppression device has the following drawbacks: the atomizing nozzle of this design does not have a cleaning mechanism. In actual use, dust inside the mine will come into contact with the atomizing nozzle, causing the dust to condense. The dust condensation will affect the spraying effect of the nozzle and the dust suppression effect inside the mine. In order to solve the above problems, a dust suppression device for coal mining is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a dust suppression device for coal mining, which solves the problem that existing atomizing nozzles do not have a cleaning mechanism. In actual use, dust inside the mine will come into contact with the atomizing nozzle, causing the dust to condense. This dust condensation will affect the spray effect of the nozzle and easily affect the dust suppression effect inside the mine.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a dust suppression device for coal mining, comprising a mounting frame and a mist cannon. An annular pipe is fixedly connected to one surface of the mist cannon, and several nozzles are fixedly connected to the circumferential side of the annular pipe. An atomizing head is connected to one surface of each nozzle, and an atomizing mesh is fixedly connected to one surface of each atomizing head. A cross bracket and a limiting plate are fixedly installed inside each nozzle. A connecting rod is installed inside the cross bracket, and an annular block is fixedly connected to one end of the connecting rod. Several second fan blades are fixedly connected to the circumferential side of the connecting rod. A limiting groove is formed on the upper surface of the limiting plate, and a top rod is installed within the limiting groove. A striking block is fixedly connected to one end of the top rod, and a push-pull rod connects the top rod and the annular block.

[0008] Preferably, a filter screen is fixedly connected to one surface of the fog cannon, a connecting frame is fixedly connected to one surface of the filter screen, a first motor is fixedly installed inside the connecting frame, a drive rod is fixedly connected to the output end of the first motor, a plurality of first fan blades and a plurality of cleaning brushes are fixedly connected to the peripheral side of the drive rod, a water tank is fixedly installed inside the mounting frame, a water pump is fixedly connected to the upper surface of the mounting frame, a water supply pipe and a water suction pipe are fixedly connected to the water pump, one end of the water suction pipe extends into the water tank, a water inlet is opened on one surface of the water tank, and one end of the water supply pipe is fixedly connected to an annular pipe.

[0009] Preferably, a second motor is fixedly installed on the top surface of the inner wall of the mounting frame, a first rotating rod is fixedly connected to the output end of the second motor, a turntable is fixedly connected to the upper end of the first rotating rod, an adjustment frame is fixedly connected to the upper surface of the turntable, and a plurality of second rotating rods are rotatably connected inside the adjustment frame, with one end of the second rotating rod fixedly connected to the fog cannon.

[0010] Preferably, both the top rod and the annular block are hinged to the push-pull rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting a second fan blade and a striking block, allows the water pump to deliver water to the annular pipe through the water supply pipe. The annular pipe further delivers water into the nozzle. After the water enters the nozzle, due to the rapid flow of the water, it encounters the second fan blade, causing the second fan blade to rotate. The second fan blade drives the rotating block to rotate through the connecting rod. When the rotating block rotates, it pulls the top rod to move through the push-pull rod. Under the limiting action of the limiting plate, the top rod can only move up and down. The top rod strikes the nozzle through the striking block, causing the nozzle to vibrate. This can shake off the dust condensed on the surface of the atomizing mesh, thereby preventing it from affecting the spray effect of the nozzle and the dust suppression effect in the mine.

[0016] 2. This utility model, by setting a cleaning brush and a first fan blade, allows the nozzle to spray water and air while the first motor drives the drive rod to rotate. The drive rod simultaneously drives the cleaning brush and the first fan blade to rotate. The rotation of the first fan blade allows the water and air to be blown further, thereby expanding the dust removal range of the equipment. While the first fan blade rotates, the cleaning brush follows the drive rod to rotate. The cleaning brush can clean the filter screen and prevent the filter screen from being blocked by dust, which would affect the air output of the equipment.

[0017] 3. This utility model sets up a first rotating rod and a second rotating rod. The second motor drives the first rotating rod to rotate, and the first rotating rod further drives the turntable to rotate, realizing the lateral rotation of the fog cannon. A third motor is fixedly installed on the front surface of the adjustment frame. The output end of the third motor is fixedly connected to the second rotating rod. The third motor drives the second rotating rod to rotate, and the second rotating rod further drives the fog cannon to rotate up and down, realizing the longitudinal angle adjustment of the fog cannon and further expanding the spray dust suppression range of the equipment.

[0026] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figures 1-4As shown, this utility model is a dust suppression device for coal mining, including a mounting frame 1 and a mist cannon 2. An annular pipe 7 is fixedly connected to one surface of the mist cannon 2. Several nozzles 8 are fixedly connected to the circumferential side of the annular pipe 7. An atomizing head 9 is connected to one surface of each nozzle 8, and an atomizing mesh 19 is fixedly connected to one surface of each atomizing head 9. A cross bracket 20 and a limiting plate 25 are fixedly installed inside each nozzle 8. A connecting rod 21 is installed inside the cross bracket 20. An annular block 23 is fixedly connected to one end of the connecting rod 21. Several second fan blades 22 are fixedly connected to the circumferential side of the connecting rod 21. A limiting groove is formed on the upper surface of the limiting plate 25. A top rod 26 is installed in the limiting groove. A striking block 27 is fixedly connected to one end of the top rod 26. A connection is made between the top rod 26 and the annular block 23. The push-pull rod 24, through the setting of the second fan blade 22 and the striking block 27, allows the water pump 4 to send water to the annular pipe 7 via the water supply pipe. The annular pipe 7 further sends water into the nozzle 8. After the water enters the nozzle 8, due to the rapid flow of the water, it encounters the second fan blade 22, causing the second fan blade 22 to rotate. The second fan blade 22 drives the rotating block 23 to rotate via the connecting rod 21. When the rotating block 23 rotates, it pulls the top rod 26 to move via the push-pull rod 24. Under the limiting action of the limiting plate 25, the top rod 26 can only move up and down. The top rod 26 strikes the nozzle 8 through the striking block 27, causing the nozzle 8 to vibrate. This can shake off the dust condensed on the surface of the atomizing net 19, thereby avoiding the clogging of the atomizing head 9 and avoiding affecting the dust reduction effect in the mine.

[0028] A filter screen 10 is fixedly connected to one surface of the fog cannon 2. A connecting frame is fixedly connected to one surface of the filter screen 10. A first motor 11 is fixedly installed inside the connecting frame. A drive rod 12 is fixedly connected to the output end of the first motor 11. Several first fan blades 13 and several cleaning brushes 16 are fixedly connected to the periphery of the drive rod 12. A water tank 3 is fixedly installed inside the mounting frame 1. A water pump 4 is fixedly connected to the upper surface of the mounting frame 1. The water pump 4 is fixedly connected to a water supply pipe and a water suction pipe. One end of the water suction pipe extends into the water tank 3. A water inlet is opened on one surface of the water tank 3 for water supply. One end of the pipe is fixedly connected to the annular pipe 7. By setting up a cleaning brush 16 and a first fan blade 13, while the nozzle 8 is spraying water and air, the first motor 11 drives the drive rod 12 to rotate. The drive rod 12 simultaneously drives the cleaning brush 16 and the first fan blade 13 to rotate. The rotation of the first fan blade 13 allows the water and air to be blown further, thereby expanding the dust removal range of the equipment. While the first fan blade 13 is rotating, the cleaning brush 16 follows the drive rod 12 to rotate. The cleaning brush 16 can clean the filter screen 10, preventing the filter screen 10 from being clogged by dust and affecting the air output of the equipment.

[0029] A second motor 17 is fixedly installed on the top surface of the inner wall of the mounting frame 1. A first rotating rod 18 is fixedly connected to the output end of the second motor 17. A turntable 5 is fixedly connected to the upper end of the first rotating rod 18. An adjusting frame 6 is fixedly connected to the upper surface of the turntable 5. Several second rotating rods are rotatably connected inside the adjusting frame 6. One end of the second rotating rod is fixedly connected to the fog cannon 2. By setting the first rotating rod 18 and the second rotating rod, the second motor 17 drives the first rotating rod 18 to rotate. The first rotating rod 18 further drives the turntable 5 to rotate, realizing the lateral rotation of the fog cannon 2. A third motor is fixedly installed on the front surface of the adjusting frame 6. The output end of the third motor is fixedly connected to the second rotating rod. The third motor drives the second rotating rod to rotate. The second rotating rod further drives the fog cannon 2 to rotate up and down, realizing the longitudinal angle adjustment of the fog cannon 2 and further expanding the spray dust suppression range of the equipment.

[0030] Both the push rod 26 and the annular block 23 are hinged to the push rod 24.

[0031] The top rod 26 is slidably engaged with the limiting plate 25, and the connecting rod 21 is rotatably connected to the cross bracket 20.

[0032] The drive rod 12 is rotatably connected to the filter screen 10, and the cleaning brush 16 is in frictional engagement with the filter screen 10. The function of the filter screen 10 is to block external dust and impurities during the blowing process of the first fan blade 13 driven by the motor 11, so as to prevent dust and impurities from adhering to the first fan blade 13 through the direction of the filter screen 10 and affecting the blowing effect of the first fan blade 13.

[0033] The upper surface of the mounting bracket 1 is provided with a guide rail 14, and a guide block 15 is slidably connected inside the guide rail 14. The guide block 15 is fixedly connected to the turntable 5.

[0034] Example:

[0035] like Figures 1-4As shown, the method of using a dust suppression device for coal mining according to this utility model is as follows: When using this utility model, multiple locking casters are installed on the bottom surface of the mounting frame 1 (not shown in the figure). Move the device into the mine, then connect the device to the power supply. The water pump 4 delivers water to the annular pipe 7 through the water supply pipe. The annular pipe 7 further delivers water into the nozzle 8. After the water enters the nozzle 8, due to the rapid flow of water, it encounters the second fan blade 22, causing the second fan blade 22 to rotate. The second fan blade 22 drives the rotating block 23 to rotate through the connecting rod 21. When the rotating block 23 rotates, it pulls the top rod 26 to move through the push-pull rod 24. Under the limiting action of the limiting plate 25, the top rod 26 can only move up and down. The top rod 26 strikes the nozzle 8 through the striking block 27, causing the nozzle 8 to vibrate, which can shake off the dust condensed on the surface of the atomizing mesh 19, thereby preventing the atomizing head 9 from clogging. While the nozzle 8 sprays water vapor, the first motor 11 drives the drive rod 12 to rotate. The drive rod 12 simultaneously drives the cleaning brush 16 and the first fan blade 13 to rotate. The rotation of the first fan blade 13 allows the water vapor to be blown further, thereby expanding the dust removal range of the equipment. While the first fan blade 13 rotates, the cleaning brush 16 follows the drive rod 12 to rotate. The cleaning brush 16 can clean the filter screen 10 to prevent the filter screen 10 from being blocked by dust and affecting the air output of the equipment. The second motor 17 drives the first rotating rod 18 to rotate. The first rotating rod 18 further drives the turntable 5 to rotate, realizing the lateral rotation of the fog cannon 2. The front surface of the adjusting frame 6 is fixedly installed with a third motor. The output end of the third motor is fixedly connected to the second rotating rod. The third motor drives the second rotating rod to rotate. The second rotating rod further drives the fog cannon 2 to rotate up and down, realizing the longitudinal angle adjustment of the fog cannon 2 and further expanding the spray dust reduction range of the equipment.
