Description

An air-driven sprayer with adjustable atomization

technical field

The utility model relates to the technical field of air-sent sprayers, which is an air-sent sprayer with adjustable atomization.

Background technique

The sprayer atomizes the normal water into certain fine water mist particles through the high-pressure atomization system including high-pressure water pump, high-pressure water circuit and air atomization nozzle, and uses the water mist particles and the dust in the air to capture, aggregate, and settle. To suppress dust and haze, the sprayers used in the current working conditions are generally fixed, and the work site and work objects are all unified. There is no need to change the range of the fog cannon and the water flow rate, and the number and flow rate of the air atomizing nozzles on the sprayer machine Fixed unity. The sprayer cannot adapt to the requirements of mobile operations. It cannot change the size of the atomized particles of the nozzle according to the distance of the operation object to make it reach the required range. At the same time, it cannot adjust the number of nozzles used according to the scope of work and the degree of pollution of the work environment. , While ensuring the dust suppression effect, save water and energy as much as possible, and improve the operating efficiency of the vehicle.

In order to achieve the above object, the utility model adopts the following technical solutions:

An air-driven sprayer with adjustable atomization, including a base box, a high-pressure water pump and a spray barrel. The table is connected with the spray tube through the support frame, and the air outlet end of the spray tube is provided with more than two water spray rings arranged concentrically, and the water inlet ends of each water spray ring are respectively connected with the water outlet ends of the high-pressure water pump through pipelines, and The pipes connected to the water inlet of each water spray circle are respectively equipped with control valves; each water spray circle is equipped with a plurality of nozzles uniformly arranged along the circumferential direction, and the spray diameters of the nozzles on the same water spray circle are all the same, and different spray nozzles The nozzles on the hydrosphere have different jet calibers.

There are two water spray rings, namely an inner water spray ring and an outer water spray ring, and the spray diameter of the nozzles on the inner water spray ring is smaller than the spray diameter of the nozzles on the outer water spray ring.

The support frame includes a base plate, and both sides of the base plate are provided with a support and an oil cylinder, the lower end of the support is fixed on the rear end of the base plate, the upper end of the support is hinged with one end of the air inlet of the spray tube, and the bottom of the oil cylinder is connected with the bottom of the base plate. The front end is hinged, and the end of the piston rod of the oil cylinder is hinged with the middle of the spray barrel.

The control valve is a ball valve.

The utility model adopts the above technical scheme. The air atomizing nozzle of the sprayer adopts the structure installation of multi-circle water spray rings. The flow rate of the nozzles on each water spray ring is different. Operation. When the operation object is far away and the range is small, the nozzle with small flow rate is used, the atomized particles are smaller, and the atomized particles have a longer range under the same wind pressure and air volume, so that it can achieve long-distance operation; when the operation object is close and In the case of a small range, use a nozzle with a large flow rate, the atomized particles will become larger, and the range of the atomized particles will be closer, making it suitable for short-distance operations; when it is necessary to perform full-range operations, use all nozzles on all water spray rings to work at the same time. According to the scope of work and the degree of pollution of the work environment, the flow rate and the number of nozzles can be changed, which can save water and energy while ensuring the dust suppression effect, and improve the work efficiency of the vehicle.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail;

Fig. 1 is a structural schematic diagram of an adjustable atomization air-driven sprayer of the present invention.

detailed description

As shown in Figure 1, the utility model comprises a base box body 1, a high-pressure water pump 2 and a spray tube 3, the high-pressure water pump 2 is arranged in the base box body 1, and the top of the base box body 1 is provided with a rotating support platform 4, and the rotating support The platform 4 is connected with the spray tube 3 through the support frame, and the air outlet end of the spray tube 3 is provided with more than two water spray rings arranged concentrically, and the water inlet ends of each water spray ring are respectively communicated with the water outlet ends of the high-pressure water pump 2 through pipelines , and the pipeline connected to the water inlet of each water spray ring is respectively equipped with a control valve, and the control valve is a ball valve; each water spray ring is equipped with a plurality of nozzles uniformly arranged along the circumferential direction, and the spraying of the nozzles on the same water spray ring The calibers are all the same, and the spray calibers of the nozzles on different spray rings are different.
