Embodiment Construction

[0019] Attached below figure 1 The present invention will be further described.

[0020] A cleaning tool for spraying equipment, comprising: an exhaust port 6 connected to the workshop ventilation duct, an air duct 2, a connecting pipe 7 and an air intake duct 8, the upper end of the air duct 2 is connected to the air exhaust port 6, and the lower end is connected to the waste liquid bucket 10 connected, the air pipe 2 is provided with the liquid inlet 3, the tail end of the connecting pipe 7 is connected with the liquid inlet 4, the paint spray gun is inserted into the mouth of the connecting pipe 7 head end, the air pipe 2 is located at the liquid inlet 3 An air inlet 4 is arranged above, the tail end of the air inlet pipe 8 is connected to the air inlet 4, and the head end thereof is connected to the air compressor through a shut-off valve 9 . When in use, open the shut-off valve 9, compressed air enters the air duct 2 through the intake pipe 8, insert the spray gun into t...

Abstract

A spraying equipment cleaning tool comprises an exhaust port, an air hose, a connecting pipe and an air inlet pipe which are communicated with a workshop ventilating duct. A stop valve is switched on, compressed air enters the air hose through the air inlet pipe, a spraying gun is inserted into a pipe orifice at the head end of the connecting pipe, a trigger is pressed when the spraying gun is cleaned, oil paint inside the spraying gun enters the air hose through the connecting pipe, the compressed air enters the air hose to take an air inlet as a cut-off point, one part of gas flows downwards to press the oil paint into a waste liquid barrel to be stored, and the other part of gas flows upwards, so that negative pressure is generated, gas generated when the oil paint inside the air hose is volatilized is fed into the exhaust port under the negative pressure and exhausted through the workshop ventilating duct, the phenomenon that detonation risks are caused when combustible liquid is mixed with gas and air is avoided, and the tool is easy and convenient to use, the cost is low, and the service life is long. An existing electric explosion-proof fan scheme is replaced, the overall system adopts pneumatic components, and potential safety hazards caused by replacement of transmission electric equipment during spraying gun cleaning are avoided.

Description

technical field [0001] The invention relates to a cleaning tool for spraying equipment. Background technique [0002] In most cases, modern aircraft maintenance companies usually use electrostatic pumps, electrostatic spray guns and other equipment for aircraft painting. Due to the large area of ​​the aircraft body, in order to meet the painting interval, generally speaking, it is necessary to arrange to use 2 pumps and 4 guns or even 4 pumps and 8 guns. mode to complete the entire painting job. [0003] After the aircraft is painted, the last step is to clean the inside and outside of the equipment used in the painting process. Because electrostatic pumps and electrostatic spray guns are expensive, if they are not cleaned in time, the internal channels will be blocked after the paint is cured, which is extremely difficult to repair, and even has to be scrapped. And because most of the equipment is foreign products, repair parts cost several thousand or even tens of thousa...
