Description

Cleaning tool for spraying equipment

Technical Field

The invention relates to a cleaning tool for spraying equipment.

Background

Modern aircraft maintenance enterprises, under most circumstances, to the aircraft equipment such as electrostatic pump, electrostatic spray gun that usually uses, because of aircraft organism area is big, in order to satisfy the interval time that sprays paint, generally speaking, need arrange the mode of using 2 pumps 4 rifle or even 4 pumps 8 rifle, accomplish whole operation work of spraying paint.

After the paint spraying of the airplane is finished, the last link is to clean the equipment used in the paint spraying process inside and outside. Because the price of the electrostatic pump and the electrostatic spray gun is high, if the electrostatic pump and the electrostatic spray gun are not cleaned in time, the paint can block an internal channel after being cured, and is extremely difficult to repair, even the paint has to be scrapped. And because most equipment is foreign products, the repair accessories are thousands of yuan or even ten thousand yuan. Therefore, the relevant equipment must be cleaned with a solvent in time.

At present, most cleaning solvents are combustible, solvent volatile matters generated in the cleaning process and paint mist have certain toxicity, and potential harm is also caused to the physical health of operators. Therefore, when cleaning the spray gun, attention is paid to explosion prevention and indoor ventilation.

The method generally adopted is that a closed container is manufactured, an explosion-proof fan is used for pumping mixed mist out of a room, and a solvent and paint mixed solution is collected through the container and treated as hazardous waste liquid in a unified manner.

In the use process, the paint components in the paint mist can be adsorbed on the collecting container, the inner wall of the air duct and the fan blade, gradually grow into a thick layer, and are extremely difficult to clean. The whole set of cleaning equipment with high cost has very short service life.

Disclosure of Invention

In order to overcome the defects of the technology, the invention provides the cleaning tool for the spraying equipment, which can completely pump out the mixed mist generated in the cleaning process and can also collect the cleaning waste liquid.

The technical scheme adopted by the invention for overcoming the technical problems is as follows:

a spray coating device cleaning tool comprising: air vent, tuber pipe, connecting pipe and the intake pipe that is linked together with workshop air pipe, the tuber pipe upper end links to each other with the air exit, and its lower extreme links to each other with the waste liquid bucket, be provided with on the tuber pipe with the inlet, the connecting pipe tail end links to each other with the inlet, and the paint spray gun inserts in the mouth of pipe of connecting pipe head end, the top that just is located the inlet on the tuber pipe is provided with the air inlet, and the intake pipe tail end links to each other with the air inlet, and its head end passes through the stop valve and connects in air compressor.

In order to prevent the exhaust port from being blocked, a Z-shaped bending part is arranged on the air pipe and above the liquid inlet.

In order to further filter the gas, the tail end of the exhaust port is provided with filter cotton.

In order to prevent static electricity, the connecting pipe is made of plastic materials.

In order to improve the operation comfort, the head end of the connecting pipe is bent upwards in an inclined mode, and the inclined angle of the head end of the connecting pipe is 45 degrees.

For the sake of beauty and safety, the device also comprises a protective cover, and the waste liquid barrel and the air pipe are both positioned in the protective cover.

In order to prevent static electricity, the protective cover is made of wood plates in a splicing mode.

The invention has the beneficial effects that: open the stop valve, compressed air passes through during the intake pipe gets into the tuber pipe, insert connector head end mouth of pipe department with the spray gun, the trigger is pulled when wasing the spray gun, paint in the spray gun gets into the tuber pipe through the connecting pipe in, compressed air uses the air inlet as the demarcation point after getting into the tuber pipe, partly gaseous downward flow is impressed paint and is stored in the waste liquid bucket, another part is gaseous upwards flows, produce the negative pressure, the volatile gas of paint in the tuber pipe is sent into exhaust port department under the negative pressure effect, discharge through the workshop ventilation pipe, prevent that combustible liquid and gas and air mixing from taking place the danger of detonation, high durability and convenient use, low manufacturing cost, long service life. The scheme of original electronic explosion-proof fan has been replaced, and whole system adopts pneumatic element, replaces the potential safety hazard when transmission electrical equipment leads to wasing the spray gun.

Drawings

FIG. 1 is an exploded view of a three-dimensional structure of the present invention;

in the figure, 1, a shield 2, an air pipe 3, a liquid inlet 4, an air inlet 5, a bent part 6, an air outlet 7, a connecting pipe 8, an air inlet pipe 9, a stop valve 10 and a waste liquid barrel are arranged.

Detailed Description

The invention is further described below with reference to fig. 1.

A spray coating device cleaning tool comprising: air vent 6 that is linked together with workshop air pipe, tuber pipe 2, connecting pipe 7 and

intake pipe

8, 2 upper ends of tuber pipe link to each other with air exit 6, its lower extreme links to each other with waste liquid bucket 10, be provided with on the tuber pipe 2 with inlet 3, 7 tail ends of connecting pipe link to each other with inlet 4, the paint spray gun inserts in the mouth of pipe of 7 head ends of connecting pipe, the top that just is located inlet 3 on the tuber pipe 2 is provided with air inlet 4, 8 tail ends of intake pipe link to each other with air inlet 4, its head end passes through stop valve 9 and connects in air compressor. During the use, open stop valve 9, compressed air passes through intake pipe 8 and gets into in the tuber pipe 2, insert 7 first end pipe orifices departments of connecting pipe with the spray gun, the trigger is withheld when wasing the spray gun, paint in the spray gun gets into tuber pipe 2 through connecting pipe 7 in, compressed air uses air inlet 4 as the demarcation point behind the entering tuber pipe 2, partly gaseous downward flow is impressed paint and is stored in waste liquid bucket 10, another part gaseous upward flow, produce the negative pressure, the volatile gas of paint in the tuber pipe 2 sends into gas vent 6 under the negative pressure effect, discharge through the workshop ventilation pipe, prevent that combustible liquid and gas and air mix and take place the detonation danger, high durability and convenient use, low manufacturing cost, long service life. The scheme of original electronic explosion-proof fan has been replaced, and whole system adopts pneumatic element, replaces the potential safety hazard when transmission electrical equipment leads to wasing the spray gun.

Furthermore, a zigzag bending part 5 is arranged on the air pipe 2 and above the liquid inlet 4. When the air in the air pipe 2 goes upwards, a vortex is formed through the bent part of the bent part 5, so that the blockage of the paint mist at the air outlet 6 can be reduced. The tail end of the exhaust port 6 can be provided with filter cotton. The filter cotton can be discharged after filtering the air of the paint mist volatilized upwards, so that the filtering effect can be further improved. The connecting pipe 7 is made of plastic, and the connecting pipe 7 made of plastic can prevent static electricity generated when the spray gun is inserted and prevent the spray gun from generating adverse chemical reaction with metal materials when being cleaned. Preferably, the head end of the connecting pipe 7 is bent upward at an angle of 45 °. The insertion of the lance at 45 ° may improve the ease of operation.

The waste liquid barrel can further comprise a protective cover 1, and the waste liquid barrel 10 and the air pipe 2 are positioned in the protective cover 1. The whole cleaning tool of the spraying equipment is sealed by the shield 1, so that the appearance is attractive, and the use safety can be further improved. Preferably, the cover 1 is made by splicing wooden plates. The wood material can effectively prevent static electricity and further improve the safety.
