Description

Technical Field

[0001] The invention relates to the technical field of open-air dust control, and in particular to an open-air dust control device. Background Art

[0002] As one of the main culprits of environmental pollution, open-air dust is one of the headaches in the engineering field. Working in a dusty working environment for a long time will cause occupational diseases such as pneumoconiosis. Therefore, dust control is indispensable in the construction process of various projects. The existing dust control device is generally a fog cannon. The fog cannon consists of a wind tube, an atomizing nozzle arranged in front of the wind tube, and a fan arranged behind the wind tube. It uses wind to drive the water mist to spray out, and condense and settle with the dust particles in the air. The range of the existing fog cannon is changed by changing the speed of the fan, which in turn increases the range and expands the spraying area. This adjustment method is single, and as the speed increases, the energy consumption increases, which is not energy-saving and environmentally friendly. A new adjustment mechanism is first proposed to increase the range of the fog cannon. Compared with the traditional fog cannon, it achieves the same range with lower energy consumption and is energy-saving and environmentally friendly.

[0003] The patent with application number 202210680283.3 discloses an open-air dust control device, including: a wind cylinder, the wind cylinder is composed of a large cylinder and a small cylinder, a fan is provided at one end of the large cylinder, the small cylinder is truncated and an atomizing nozzle is provided at the small end of the small cylinder; an adjusting tube, the first end of the adjusting tube is fixed on the inner wall of the large cylinder; the second end of the adjusting tube is fixed on the inner wall of the small cylinder; an adjusting assembly, the adjusting assembly includes several groups of sliding mechanisms, the sliding mechanism includes: a screw rod and a slide rod, both ends of the screw rod are rotatably fixed on the outer wall of the small cylinder, a slide groove is provided on the cylinder wall of the small cylinder, the slide rod is arranged through the slide groove and one end of the slide rod is connected to the screw rod through a threaded hole, and the other end of the slide rod is arranged inside the small cylinder and abuts the adjusting tube; a driving member, the driving member drives the screw rod to rotate.

[0004] The above technical solution utilizes a motor and a screw rod to drive the sliding rod to move from the large end of the small tube to the small end, and adjusts the inner wall of the small tube during the movement. Although the shape of the center position of the inner wall of the small tube can be adjusted, the size of the air outlet of the small tube is constant, and no matter how the shape of the inner wall of the small tube is adjusted, the air outlet diameter will not change, and the effect of high flow rate in a small space cannot be achieved, and the air flow rate and range cannot be improved. In addition, the installation of electrical equipment such as motors leads to an increase in the energy consumption of the dust control device. Therefore, the present application provides an open-air dust control device to meet the needs. Summary of the invention

A first conveying pipe is installed at the bottom end of the conveying frame, and atomizing nozzles are arranged in an annular array on the side wall of the conveying frame. A second conveying pipe connected to the water storage bag is installed on the side wall of the first conveying pipe, and a gas release component is arranged at the top end of the second conveying pipe.

[0008] Optionally, a tee pipe is installed between the first conveying pipe and the second conveying pipe. A drain pipe is fixed at the bottom end of the tee pipe, and a control valve is installed on the drain pipe.

[0009] Optionally, a rotating plate is embedded at the top end of the water storage tank, and a driving motor is fixedly installed on the top wall of the water storage tank. Heat dissipation grooves are opened on both sides of the top surface of the water storage tank.

[0010] Optionally, a driving shaft is installed at the top end of the driving motor. The top end of the driving shaft passes through the water storage tank and is fixedly sleeved with a driving gear. A driven gear is fixedly sleeved on the rotating plate, and the driven gear is meshed with the driving gear.

[0012] Optionally, a load-bearing rod connected to the conveying frame is obliquely fixed on the side wall of the installation frame, and an adjusting motor is fixed on the outer wall of the installation frame. Pin shafts rotatably inserted into the installation frame are fixed on both sides of the outer wall of the dust control cannon barrel, and the adjusting motor is fixedly connected to the pin shafts.

[0013] Optionally, a solenoid valve is installed at the bottom end of the second conveying pipe. The gas release component includes a suction pipe fixed at the top end of the side wall of the second conveying pipe and an air outlet pipe fixed on the suction pipe.

[0014] Optionally, one end of the second delivery pipe is slidably inserted with a connecting rod, and the other end of the second delivery pipe is fixedly embedded with a first one-way valve.

[0015] Optionally, a second one-way valve is installed in the air outlet pipe, a piston for sealing the air outlet pipe is embedded in the pumping pipe, and a sealing ring tightly connected to the inner wall of the pumping pipe is fixedly embedded on the outer wall of the piston.

[0035] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides an open-air dust control device, including a water storage tank 7 and a dust control cannon 1 adjustably arranged at the top of the water storage tank 7.

The fastening bolt 31 is threadedly inserted into the pumping pipe 28 to seal the air outlet pipe 30 by the piston 25. After the water storage bladder 4 is filled with water, it expands, and after expansion, the water storage bladder 4 blocks the inner wall of the dust control gun barrel 1, reducing the air outlet space of the dust control gun barrel 1. By reducing the size of the air outlet of the dust control gun barrel 1, the flow rate of the wind force conveyed by the fan 20 is increased, and without increasing power equipment, the lift of the dust control gun barrel 1 is increased.

[0037] As Figures 3 to 6 shown, a driving shaft 22 is installed at the top end of the driving motor 23. The top end of the driving shaft 22 passes through the water storage tank 7 and is fixedly sleeved with a driving gear 6. A driven gear 21 is fixedly sleeved on the rotating plate 18. The driven gear 21 is meshed and connected with the driving gear 6. An installation rack 9 is fixed to the top end of the rotating plate 18. A support pipe 16 embedded in the rotating plate 18 is fixed in the installation rack 9. The first delivery pipe 5 is embedded in the support pipe 16, and a water pump is installed at the end of the first delivery pipe 5 extending into the water storage tank 7. After the driving motor 23 is started, it drives the driving shaft 22, the driving gear 6, the driven gear 21 and the rotating disk to rotate, and adjusts the directions of the installation rack 9 and the dust control gun barrel 1 during the rotation. After the adjusting motor 10 is started, it adjusts the angle of the dust control gun barrel 1.

[0038] A load-bearing rod 17 connected to the delivery rack 2 is obliquely fixed to the side wall of the installation rack 9, and an adjusting motor 10 is fixed to the outer wall of the installation rack 9. Pin shafts rotatably inserted into the installation rack 9 are fixed to both sides of the outer wall of the dust control gun barrel 1. The adjusting motor 10 is fixedly connected with the pin shafts. A solenoid valve 15 is installed at the bottom end of the second delivery pipe 14. The air release assembly includes a pumping pipe 28 fixed to the top end of the side wall of the second delivery pipe 14 and an air outlet pipe 30 fixed to the pumping pipe 28. One end of the second delivery pipe 14 is slidably inserted with a connecting rod 26, and a first one-way valve 24 is fixedly embedded at the other end of the second delivery pipe 14. A second one-way valve 29 is installed in the air outlet pipe 30. A piston 25 for sealing the air outlet pipe 30 is embedded in the pumping pipe 28. A sealing ring closely connected with the inner wall of the pumping pipe 28 is fixedly embedded on the outer wall of the piston 25. A pull plate 27 is arranged on the side wall of the pumping pipe 28. Both ends of the connecting rod 26 are fixedly connected with the pull plate 27 and the piston 25 respectively. A fastening bolt 31 fixed to the pumping pipe 28 is arranged on the pull plate 27.

[0039] The working principle of the technical solution provided by the present invention is as follows:

[0040] When in use, start the water pump to convey the water in the water storage tank 7 into the first conveying pipe 5. The first conveying pipe 5 discharges the water from the atomizing nozzle 3 through the conveying frame 2. Open the solenoid valve 15 on the second conveying pipe 14, so that the first conveying pipe 5 injects water into the water storage bag 4 through the second conveying pipe 14. The fastening bolt 31 is threadedly inserted into the pumping pipe 28 to seal the air outlet pipe 30 by the piston 25. After the water storage bag 4 is filled with water, it expands, and after expansion, the water storage bag 4 blocks the inner wall of the dust suppression cannon 1 and reduces the air outlet space of the dust suppression cannon 1. By reducing the air outlet size of the dust suppression cannon 1, the flow rate of the wind conveyed by the fan 20 is increased. Without increasing the power equipment, the lift of the dust suppression cannon 1 is increased. After opening the control valve 12 on the drain pipe 13 and the solenoid valve 15 on the second conveying pipe 14, the water in the water storage bag 4 is discharged. After discharging, unscrew the fastening bolt 31, drive the connecting rod 26 and the piston 25 to slide through the pull plate 27, and during the sliding process, the residual water and air in the water storage bag 4 are pumped out through the first one-way valve 24, and the pumped water and air are discharged from the second one-way valve 29 and the air outlet pipe 30 during the extrusion process, so as to make the storage bag contract and reduce the air outlet space of the dust suppression cannon 1.
