CN2374273Y - Multifunctional pneumatic spraying coating device - Google Patents

Abstract

The utility model relates to a multifunctional pneumatic spraying device which applies pressure on liquid level by gas. A liquid outlet receives same pressure which is equal to the pressure of gas, and one set of pneumatic atomizer is formed after an atomizing device is arranged. The pneumatic spraying device applies pressure on liquid only by gas, and does not consume gas during the work. Thereby, one series defects of general siphoning type spraying are overcome. The utility model meets the requirements of small size, light weight, less power consumption, low noise, low cost and small environmental pollution, and can also be combined into multifunction. High water pressure is generated with the same principle to carry out high-pressure cleaning for facilities such as vehicles, etc. One machine can perform many functions.

Description

Multi-functional air pressure spray equipment

Product surface spray coating device commonly used, be to utilize compressed air to pass through nozzle ejection, produce negative pressure at nozzle exit, thereby sprayed workpiece with (as the paint) sucking-off of the coating in the receiver and with the jet-stream wind directive, finish product surface spray coating decoration and antirust, this technology often is called the hydrocone type spraying.The hydrocone type spraying needs relatively large compressed air to produce siphonic effect, and must spray from nozzle by continuous flow, in case nozzle place closed gas flow just can not produce siphonage; The coating that comes out from the receiver siphon is along with the air-flow of nozzle ejection directive is together sprayed the workpiece process, and coating is space splash towards periphery seriously, and wastage is very big, and surrounding environment is polluted, and operating personnel's health is brought harm; Because a large amount of compressed air of hydrocone type consumption, the capacity of air compressor there is very big requirement, so corresponding volume, weight, noise, the cost that increases the pneumatics unit especially increased power consumption.A series of defectives that the utility model brings at the above hydrocone type spraying technology adopt pneumatic spraying and achieve the goal.Pneumatic spraying is to utilize gas that liquid surface is exerted pressure, and liquid outlet is placed in liquid bottom, forms same gas barrier, and during the liquid surface pressurized, liquid just is pressed out to atomizer from liquid outlet, sprays to surface of the work after atomizing.

Below in conjunction with accompanying drawing the utility model is described further.

The length of the path circle of the spool of piston valve (A) is half of porting distance; The inlet suction port of receiver (B) is installed in a jar upside, and the drain pipe outlet then is installed in a jar bottom.When spraying work, the piston valve position as shown in the figure, Compressed Gas enters fluid reservoir (B) along solid line by way of piston valve (A), liquid surface in (B) is exerted pressure, liquid outlet is because of being immersed in the liquid, so gas can not be discharged from, liquid then is pressed out to atomizer (C) from the exit along solid line behind pressurized, be mapped to working face after liquid is atomized, and finish spraying work.

When needs quit work, should be in time with the Compressed Gas emptying in the receiver, the utility model is the effect that utilizes linked switch, as shown in drawings, the piston valve piston is moved to the left piston when closing air inlet, the fluid reservoir pipeline just has been communicated with atmosphere, and Compressed Gas discharges along dotted line head direction in jar.Thereby to the fluid reservoir release, liquid just stops to enter atomizer (C)

Compressed gas consuming not when the utility model can make device busy, and the very little a part of Compressed Gas of discharging when quitting work just, thereby very little, energy savings significantly to the gas source and flow amount demand.

The utility model device also can be mixed some accessories, utilize the compressed air of air-source pump to be made into high pressure washer with the above principle, be used for equipment such as automobile, motorcycle are cleaned usefulness, be used for the avenue trees are cleaned, the fruit tree woods is sprayed insecticide, and, form a multi-functional air pressure spray equipment to various pneumatic tire inflations etc.

Claims (3)

1, multi-functional air pressure spray equipment, compressed air stream is through the connection of piston valve, pipeline, fluid reservoir, drain pipe, atomizer, it is characterized in that: Compressed Gas enters on the top of receiver, and promptly the inlet suction port of receiver is installed in a jar upside, and the drain pipe outlet then is installed in a jar bottom.

2, pneumatic spraying device according to claim 1 is characterized in that: the structure of piston valve (A) is that the length of the path circle of spool is half of porting distance.

3, pneumatic spraying device according to claim 1 is characterized in that: drain pipe is inserted into the bottom of receiver but does not touch the bottom, and gas and liquid outlet are isolated.
