Description

Technical Field

[0001] This invention relates to the technical field of spray dust suppression methods, and more particularly to a multi-nozzle variable spray dust suppression control method. Background Technology

[0002] During the coal mining process, coal dust is inevitably generated along with the operation of the tunneling machine. Coal dust not only obstructs the vision of the workers, but also, when inhaled, it can greatly affect their health.

[0003] Existing coal dust control methods are inconvenient for constantly changing the direction of water mist, and the diffusion range of water mist is limited, resulting in incomplete removal of coal dust. In addition, existing coal dust control methods are inconvenient for controlling the water mist spray height, resulting in insufficient diffusion range of water mist. At the same time, the density of water mist is inconvenient to adjust, often resulting in excessive water mist and excessively wet ground. Therefore, a multi-nozzle variable spray dust control method is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a multi-nozzle variable spray dust control method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The multi-nozzle variable spray dust suppression control method includes the following steps: S1. Transfer spraying equipment: Push the spraying equipment to the bottom of the coal dust that needs to be removed using a handcart; S2. Adjusting the height of the spraying equipment: By opening the cylinder, the cylinder drives the moving plate to move, the moving plate drives one end of the transmission plate to move, which in turn causes the other end of the transmission plate to lift the L-shaped lifting plate, thereby driving the atomizing nozzle to rise, thus adjusting the spraying height. S3. Constantly change the spray direction: When the motor is turned on, the motor drives the fan blades to rotate and generate wind. The wind can cause the outer spherical shell to shake continuously, which in turn causes the atomizing nozzle to shake, thus constantly changing the spray direction and increasing the spray range. S4. Spray dust suppression: Turn on the pressure pump, which delivers water from the water tank to the inner spherical shell and then sprays it out through the atomizing nozzle, so that the water is atomized and the water mist combines with the coal dust to achieve the dust suppression function. The spraying equipment includes a handcart, with a fixed sleeve plate fixedly connected to the top of the handcart. An L-shaped lifting plate is slidably connected inside the fixed sleeve plate. A suspension rope is fixedly connected to the top of the L-shaped lifting plate. A mounting shell is fixedly connected to the bottom end of the suspension rope. An outer spherical shell is fixedly connected to the bottom end of the mounting shell. Several mounting holes are opened on the surface of the outer spherical shell. Atomizing nozzles are slidably connected inside the mounting holes. An inner spherical shell is provided inside the outer spherical shell. An airbag is provided on the outside of the inner spherical shell. Several through holes are opened on the surface of the airbag. The bottom end of the atomizing nozzle passes through the through holes and is fixedly connected to the through holes. A telescopic hose is fixedly connected between the bottom end of the atomizing nozzle and the inner spherical shell. A lifting mechanism is provided at the top of the handcart.

[0006] Preferably, a miniature air pump is installed inside the mounting housing, and an air delivery pipe is fixedly connected to the output end of the miniature air pump. The air delivery pipe passes through the outer spherical shell and is fixedly connected to the airbag.

[0007] Preferably, a pressure pump and a water tank are installed on the top of the handcart, a water supply pipe is fixedly connected between the pressure pump and the water tank, and a connecting hose is fixedly connected to one end of the pressure pump.

[0008] Preferably, one end of the connecting hose passes through the outer spherical shell and the air bladder and is fixedly connected to the inner spherical shell, and the connecting hose is fixedly connected to the air bladder.

[0009] Preferably, one side of the L-shaped lifting plate is provided with a rotating through hole, and a rotating shaft is rotatably connected inside the rotating through hole. Several fan blades are fixedly connected to one end of the rotating shaft near the outer spherical shell.

[0010] Preferably, a connecting plate is fixedly connected to one side of the L-shaped lifting plate, and a motor is installed at the top of the connecting plate, with the output end of the motor fixedly connected to the rotating shaft.

[0011] Preferably, one end of the connecting plate is provided with a steering groove, and a transmission plate is rotatably connected in the steering groove.

[0012] Preferably, the lifting mechanism includes a guide rod fixedly connected to the top of the handcart, a movable plate slidably connected to the guide rod, and a cylinder installed on the top of the handcart.

[0013] Preferably, the top end of the movable plate is rotatably connected to the transmission plate, and the output end of the cylinder is fixedly connected to a push shaft, one end of which is fixedly connected to the movable plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention has a lifting mechanism that allows adjustment of the height of the L-shaped lifting plate, thereby adjusting the height of the atomizing nozzle and achieving the function of adjusting the spray height.

[0015] 2. This invention is equipped with a motor, fan blades, suspension ropes, and an outer spherical shell. The motor drives the fan blades to rotate, which generates wind. The wind pushes the outer spherical shell to sway, which in turn drives the atomizing nozzle to sway, thereby changing the spray angle and direction of the atomizing nozzle and increasing the spray range.

[0016] 3. This invention incorporates a micro air pump and an airbag. The micro air pump inflates the airbag, pushing the atomizing nozzles outwards. This allows for adjustment of the spacing between the atomizing nozzles, thereby controlling the water mist density and preventing excessive dampness on the ground. Attached Figure Description

[0019] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1-6The multi-nozzle variable spray dust suppression control method includes the following steps: S1. Transfer spraying equipment: Push the spraying equipment to the bottom of the coal dust that needs to be removed using a handcart; S2. Adjusting the height of the spraying equipment: By opening the cylinder 16, the cylinder 16 drives the moving plate 15 to move, the moving plate 15 drives one end of the transmission plate 13 to move, and then the other end of the transmission plate 13 lifts the L-shaped lifting plate 10, thereby driving the atomizing nozzle 8 to rise, so as to adjust the spraying height. S3. Change the spray direction at any time: Turn on the motor 12. The motor 12 drives the fan blade 11 to rotate and generate wind. The wind can drive the outer spherical shell 7 to shake continuously, which in turn drives the atomizing nozzle 8 to shake. This allows the spray direction to be changed at any time, increasing the spray range. S4. Spray dust suppression: Turn on the pressure pump 4. The pressure pump 4 delivers water from the water tank 3 to the inner spherical shell 6 and then sprays it out through the atomizing nozzle 8, so that the water is atomized and the water mist combines with the coal dust to achieve the dust suppression function. The spraying equipment includes a handcart 1, with a fixed sleeve 2 fixedly connected to the top of the handcart 1. An L-shaped lifting plate 10 is slidably connected inside the fixed sleeve 2. A suspension rope 9 is fixedly connected to the top of the L-shaped lifting plate 10, allowing the outer spherical shell 7 to swing freely. A mounting shell 20 is fixedly connected to the bottom of the suspension rope 9, and the outer spherical shell 7 is fixedly connected to the bottom of the mounting shell 20. The outer spherical shell 7 facilitates the installation of atomizing nozzles 8. Several mounting openings are provided on the surface of the outer spherical shell 7, and atomizing nozzles 8 are slidably connected to the mounting openings. The trolley 1 is equipped with an inner spherical shell 6, which can deliver water to each atomizing nozzle 8. An air bladder 19 is provided on the outside of the inner spherical shell 6. The expansion of the air bladder 19 can push the atomizing nozzle 8 to move, control the spacing of the atomizing nozzle 8, and thus control the density of the water mist. Several through holes are opened on the surface of the air bladder 19. The bottom end of the atomizing nozzle 8 passes through the through holes and is fixedly connected to the through holes. A telescopic hose 18 is fixedly connected between the bottom end of the atomizing nozzle 8 and the inner spherical shell 6. A lifting mechanism is provided on the top of the trolley 1, which can adjust the height of the atomizing nozzle 8.

[0021] A miniature air pump 21 is installed inside the housing 20. The output end of the miniature air pump 21 is fixedly connected to an air supply pipe, which passes through the outer spherical shell 7 and is fixedly connected to the airbag 19.

[0022] A further benefit is that the micro air pump 21 can inflate the air bladder 19, thereby controlling the spacing between the atomizing nozzles 8 and thus controlling the density of the water mist.

[0023] A pressure pump 4 and a water tank 3 are installed on the top of the handcart 1. A water supply pipe is fixedly connected between the pressure pump 4 and the water tank 3. A connecting hose 5 is fixedly connected to one end of the pressure pump 4. One end of the connecting hose 5 passes through the outer spherical shell 7 and the air bladder 19 and is fixedly connected to the inner spherical shell 6. The connecting hose 5 is fixedly connected to the air bladder 19.

[0024] A further benefit is that the pressure pump 4 can deliver water from the water tank 3 to the inner spherical shell 6, and then spray it out through the atomizing nozzle 8 to atomize the water.

[0025] One side of the L-shaped lifting plate 10 has a rotating through hole, and a rotating shaft is rotatably connected inside the rotating through hole. Several fan blades 11 are fixedly connected to one end of the rotating shaft near the outer spherical shell 7.

[0026] Further benefits include: the motor 12 drives the fan blade 11 to rotate, which generates wind, causing the outer spherical shell 7 to sway, which in turn causes the atomizing nozzle 8 to sway, thus changing the spray direction and angle of the atomizing nozzle 8 and increasing the spray range.

[0027] A connecting plate 14 is fixedly connected to one side of the L-shaped lifting plate 10. A motor 12 is installed at the top of the connecting plate 14. The output end of the motor 12 is fixedly connected to the rotating shaft. A steering groove is opened at one end of the connecting plate 14, and a transmission plate 13 is rotatably connected in the steering groove.

[0028] A further benefit is that the motor 12 can provide power for the rotation of the fan blade 11.

[0029] The lifting mechanism includes a guide rod 17 fixedly connected to the top of the handcart 1, a movable plate 15 slidably connected to the guide rod 17, and a cylinder 16 installed on the top of the handcart 1. The top of the movable plate 15 is rotatably connected to the transmission plate 13. The output end of the cylinder 16 is fixedly connected to a push shaft, and one end of the push shaft is fixedly connected to the movable plate 15.

[0030] A further advantage is that the lifting mechanism can work with the transmission plate 13 and the connecting plate 14 to lift the L-shaped lifting plate 10, thereby enabling the adjustment of the height of the atomizing nozzle 8.

[0031] Motor 12 is existing technology, model number KYDAS96300-1E, which can drive the rotating shaft to rotate, and will not be described in detail here.

[0032] The miniature air pump 21 is existing technology, model FAA4002, which can perform the functions of inflating and deflating air inside, and will not be described in detail here.

[0033] Cylinder 16 is existing technology, model KSOE-SCJ, which can drive the movement of the movable plate 15, and will not be described in detail here.

[0034] When using this invention, the spraying device is pushed to the bottom of the coal dust to be removed by a handcart. The cylinder 16 is activated, which causes the moving plate 15 to move. The moving plate 15 causes one end of the transmission plate 13 to move, which in turn causes the other end of the transmission plate 13 to lift the L-shaped lifting plate 10, thereby causing the atomizing nozzle 8 to rise, thus adjusting the spraying height.

[0035] Then, the motor 12 is turned on. The motor 12 drives the fan blade 11 to rotate and generate wind. The wind can blow the outer spherical shell 7 to shake, which in turn drives the atomizing nozzle 8 to shake. This can change the spray angle and direction of the atomizing nozzle 8, thereby increasing the spray range of the atomizing nozzle 8 and improving the efficiency of coal dust removal.

[0036] Increasing the micro air pump 21 inflates the air bladder 19, which in turn increases the spacing between the atomizing nozzles 8, thereby reducing the water mist density. Increasing the micro air pump 21 extracts the gas from the air bladder 19, which shortens the spacing between the atomizing nozzles 8, thereby increasing the water mist density. By controlling the water mist density, excessive dampness on the ground can be avoided.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
