Description

Technical Field

[0001] The utility model belongs to the field of air treatment for removing haze and suppressing dust, and in particular relates to an induced swirl spray device for a haze and dust suppression vehicle. Background Art

[0002] In modern society, environmental pollution has become a serious problem, and the country and the people are paying more and more attention to the environmental situation. Air pollution not only affects people's health, but also causes great damage to the ecosystem. Therefore, purifying the air has become an urgent task. As an important part of the total suspended particulate matter in the ambient air, dust needs to be properly controlled. In this context, the fog cannon, also known as the spray dust removal machine, as a new type of environmental protection equipment, has attracted more and more attention. The large-scale use of fog cannons has changed the ecological environment in many regions of the country. The fog cannon uses atomization dust removal technology without dust cleaning, less water consumption for dust removal, less water output to be treated, no secondary pollution, and it can also increase the moisture in the air. The spray system of the fog cannon has a certain control effect on dust. Its principle is mainly that the fog cannon atomizes water by a certain method, and then uses a fan to push the atomized water mist particles to the area where dust suppression is required. These tiny water mist particles with a radius similar to the dust radius are in direct contact with the dust in the air. After the dust has been in contact, it is moistened and then condensed into a ball with the surrounding dust through adsorption, and then the dust sinks under the action of gravity, thereby achieving the dust removal effect. In addition to removing haze and dust, fog cannons also have the functions of sprinkling water and cleaning roads.

[0003] During the research and improvement, the R&D personnel found that the water mist spraying range of the fog cannon truck was still limited, and the diameter of the water mist particles was large, resulting in a small dust removal range and high water consumption. Summary of the invention

[0004] In order to achieve the purpose of spreading water over a wider range and reducing water consumption and water supply energy consumption, the utility model provides a gas-injection swirl spray device for a haze removal and dust suppression vehicle.

[0005] The utility model provides a gas-induced swirl spray device for defogging, haze and dust suppression vehicles, which adopts the following technical solutions:

[0006] A gas-inducing swirl spray device for a haze and dust suppression vehicle comprises a spray head, two air inlet pipes and a water tank;

[0007] The gun head is rotatably arranged at one side of the upper end surface of the base through a bracket, and the barrel of the gun head adopts a Venturi structure, which includes an inlet section, a contraction section and an expansion section that are connected in sequence; a spiral device is arranged in the contraction section of the barrel, and the spiral device adopts a spiral structure that spirals upward toward the outside and has a gradually increasing radius;

[0008] The inlet section of the cylinder is connected to the blower, the bottom of the section is provided with an opening for discharging accumulated water, and the side wall of the gun head is provided with an open end; two air inlet pipes are respectively arranged outside the inlet section of the cylinder and are connected to the cylinder;

[0009] The water tank is detachably arranged at the other side of the upper end surface of the base, and the water tank is connected with the open end of the cylinder through a hose.

[0010] Preferably, the bracket is a U-shaped structure formed by welding two L-shaped tubes to ensure the stability of the bracket. The two ends of the L-shaped tube are welded to the gun head to ensure a stable connection between the bracket and the gun head, thereby achieving the purpose of increasing the service life of the spray device.

[0011] Preferably, the bracket is driven by a motor to rotate around the center line of the bracket itself; preferably, the base and the bracket are hingedly connected, and can be rotated 60 degrees to the left and right based on the vertical backward direction of the original gun head under human power or motor power, so that the water mist spraying range is wider and the dust removal effect is better. The vertical center line of the base and the bracket is consistent, which can ensure that the vertical center line based on which the gun head rotates is uniquely determined, and the rotation angles on both sides are the same without special circumstances, so as to achieve the purpose of ensuring that the spraying range of the spray device is reasonably determined.

[0012] The spray device also includes a connecting rod; the connecting rod passes through the barrel of the gun head, one end of the connecting rod is connected to the spiral device, the middle part is connected to the inner wall of the expansion section of the barrel through three short connecting rods, and the other end is welded to the inner wall of the inlet section of the barrel.

[0013] Preferably, the two air inlet pipes form an acute angle with the side wall of the inlet section of the cylinder body. The acute angle is more convenient for airflow to enter than a right angle and is not convenient for water to be blown out, thereby reducing water loss.

[0014] Preferably, the base can be configured to have a magnetic bottom, which is used to reinforce the spray device when it is fixed to a fixed end made of iron material (such as the body of a fog cannon vehicle), thereby increasing the stability of the connection between the base and the fixed end.

[0015] Preferably, both the upper end surface and the lower end surface of the water tank are provided with anti-slip patterns.

[0016] Preferably, the spiral device at the front end of the gun head is based on the working principle of a cyclone separator, but uses a spiral structure to strengthen the direction of water flow. After the water flows into the spiral device, it rotates and flows forward, and the atomized water droplets are rotated out into the atmosphere through the spiral device. The water is atomized by the spiral device to achieve the purpose of water mist refinement. In addition, due to the centrifugal effect generated by the spiral and the blowing of the fan, the water mist spraying range can be wider, thereby expanding the water mist spraying range and improving the spraying efficiency.

[0017] Preferably, anti-skid grooves are provided under the base, so that when the base is placed on a non-flat surface by mistake, it can still be relatively stable, thereby protecting people's safety during the movement of the spray device.

[0018] Preferably, the upper end of the base and the lower end of the water tank are both provided with anti-slip grooves, so that when the base and the water tank are connected together, the connection between the base and the water tank is strengthened.

[0019] The beneficial effects of the utility model are:

[0020] 1. The spiral device based on the working principle of the cyclone separator can achieve the effect of finer water mist and wider spraying range of water mist;

[0021] 2. The opening of the barrel of the gun head is directly and flexibly connected to the water tank through a hose. After the cyclone cutting, the water mist that is not fine enough returns to the water tank through the hose due to gravity, which can reuse water resources and reduce water loss;

[0022] 3. The bracket and the base are rotatably connected so that the nozzle can spray in multiple directions, thus expanding the spraying range of the spray device;

[0023] 4. The anti-slip patterns on the base and the upper and lower ends of the water tank can protect human safety when the spray device is moved manually or the direction of the gun head is changed manually. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0030] Refer to the attached Figure 1-Figure 4 The utility model discloses a gas-injection swirl spray device for a haze-removing and dust-suppressing vehicle, comprising a base 1, a gun head 2 and a water tank 3.

[0031] The base 1 is used to fix the entire spray device at a desired location, such as being installed on a fog cannon vehicle to replace the function and role of a fog cannon. The base 1 is a solid block with a square structure, and anti-slip grooves are provided on both the upper and lower ends.

[0032] The water tank 3 is installed on the base 1 and is located below the rear end of the gun head 2. The water tank 3 is used to provide the gun head 2 with sprayable water.

[0033] The gun head 2 is rotatably arranged at one side of the upper end surface of the base through a bracket 11. The bracket 11 is a U-shaped structure formed by welding two L-shaped tubes of the same size and shape. The base 1 and the bracket 11 are connected by a rotatable hinge. The bottom of the bracket 11 is driven by a motor and can rotate 60 degrees to the left and right along the vertical center line of the bracket, which can make the water mist spraying range wider and the dust removal effect better. Among them, the vertical center line of the base and the bracket is consistent, which can ensure that the vertical center line based on which the gun head rotates is uniquely determined, and the rotation angles on both sides are the same without special circumstances, so as to achieve the purpose of ensuring that the spraying range of the spray device is reasonably determined.

[0034] If the base 1 is fixed on the vehicle body, and the spray device of the fog cannon vehicle performs spraying operation while the fog cannon vehicle is moving, the rotation of the bracket 11 can be performed to avoid rotation according to the road conditions.

[0035] Reference Figure 4 The barrel of the gun head 2 is a contraction-expansion structure of a Venturi structure. Specifically, the Venturi structure includes an inlet section 201, a contraction section 202 and an expansion section 203 which are connected in sequence.

[0036] like Figure 1-Figure 2 The gun head 2 adopts a barrel, and a connecting rod 22, a spiral structure 23, a blower 24 and an air inlet pipe 25 are also arranged inside the gun head; an open end 21 is arranged on the side wall of the barrel of the gun head, and the open end 21 is arranged at the rear end of the gun head 2. The open end 21 at the rear end of the gun head 2 and the water tank 3 are directly and flexibly connected through a hose. The open end 21 and the water tank 3 are pre-connected with a hose, and the residual water droplets with a large particle diameter after being cut by the spiral structure 23 can be discharged. The water tank 3 is a square hollow box with anti-skid patterns on the upper and lower end surfaces, so as to hold the water for spraying and recover the water mist that is not fine enough. When cleaning is required or the spray device is not needed, the hose can be disassembled. The hose is a detachable device, which is convenient for cleaning the hose to avoid contaminating the water in the water tank.

[0037] A spiral device is provided in the contraction section, and the spiral device adopts a spiral structure that spirals upward toward the outside and gradually increases in radius; the spiral structure 23 can further rotate and atomize the water flow after the airflow is injected, and finally obtain water droplets with smaller particle size. Under the blowing of wind, the coverage area is wider, and the use of gas to inject water flow can reduce the energy consumption of water supply.

[0038] The connecting rod 22 is directly fixedly connected to the rear end of the gun head 2 by welding, and is indirectly connected to the front end of the gun head 2 by welding through three supporting rods 26. The spiral structure 23 is connected to the connecting rod 22 by welding. The blower 24 extends from the inlet section of the rear end of the gun head 2 through a pipeline, and is used to push water droplets into the spiral structure 23 by blowing. The bottom of the inlet section is provided with an opening for discharging accumulated water.

[0039] The air inlet pipe 25 penetrates the cylinder wall at the upper and lower surfaces of the rear end of the cylinder of the gun head 2, which is used to increase the air intake and help the water flow to blow upward along the gun head. It forms an acute angle with the cylinder wall. The acute angle is more convenient for air flow to enter and is not easy for water to be blown out, thereby reducing water loss.

[0040] In the utility model, water flows from the water tank 3 into the barrel of the gun head through a hose, the water flows upward along the Venturi structure of the barrel of the gun head through the blowing of the fan, and then is cut into water mist by the spiral structure 23, and finally blown out from the rear end 23 of the gun head 2 to achieve the purpose of dust removal.

[0041] like Figure 1-Figure 4 , the implementation principle and process of the utility model are:

[0042] When dust removal is required for a large area, the open end 21 of the gun head 2 and the water tank 3 are connected with a hose, the blower 24 is started first, the direction of the gun head 2 is adjusted, and dust is removed in that direction, and then the motor-driven bracket 11 is used to drive the gun head to rotate, the direction of the gun head 2 is adjusted, and dust is removed in other directions respectively; when large-scale dust removal is not required, only the bracket 11 is fixed to ensure that the direction of the gun head 2 can move up and down along the central vertical plane of the base but cannot move left and right, and dust removal can be continued. Water enters the barrel from the water tank 3 through the hose, and the water flow goes up along the Venturi structure of the gun head barrel through the blowing of the blower, and then is cut into water mist by the spiral structure 23, and finally blown out from the rear end 23 of the gun head 2 to achieve the purpose of dust removal. Atomization through the spiral device can achieve the purpose of water mist refinement, and because the centrifugal effect generated by the spiral and the blowing of the fan can make the water mist spraying range wider, so as to achieve the effect of expanding the water mist spraying range and improving the spraying efficiency. After cyclone cutting, the water mist that is not fine enough returns to the water tank through the hose due to gravity, which can reuse water resources and reduce water loss.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
