A closed anti-sedimentation coating machine

Abstract

The invention provides a sealed anti-precipitation paint coater. The sealed anti-precipitation paint coater comprises an agitating component which is arranged below the entire liquid level of a sealed tank body and communicated with a discharge pipe by a connecting pipe, and an air outlet pipe is provided with a plurality of agitating holes. When the paint coater conducts flow coating, a part of paint pumped into the discharge pipe by a liquid pump enters a spray gun through an on switch valve and is flow-coated on a flow coating component through the spray gun, and the other part of the paint enters the agitating component through the connecting pipe and is sprayed to the liquid level in the sealed tank body through the agitating holes in the agitating component, so that the paint in the sealed tank body is surged to be agitated, and is effectively prevented from precipitating. By virtue of the paint coater adopting the mode, an agitation shaft is not required, no external air is needed to be distributed into the tank body for agitation, and thus hidden safety hazards possibly caused by continuous increasing pressure in the tank body due to frequent air distribution can be avoided.

Description

technical field [0001] The invention relates to an anti-precipitation coating machine, which belongs to the field of flow coating equipment. Background technique [0002] Coating machine is a special coating equipment using flow coating technology, mainly composed of feeding equipment and flow coating equipment. The existing paint machines mainly have the following problems: first, when the paint that pollutes the environment is used in an open feeding device, it is easy to pollute the environment; second, the paint that is flammable and explosive When it is used in closed feeding equipment, there is a potential safety hazard that may easily cause the explosion of the feeding equipment; third, no matter for the open feeding equipment or the closed feeding equipment, the coating with higher viscosity During the coating process, it is easy to deposit on the bottom of the supply equipment, making flow coating difficult. Therefore, for the field of flow coating technology, it ...

AI Technical Summary

Problems solved by technology

The existing paint machines mainly have the following problems: first, when the paint that pollutes the environment is used in an open feeding device, it is easy to pollute the environment; second, the paint that is flammable and explosive When it is used in closed feeding equipment, there is a potential safety hazard that may easily cause the explosion of the feeding equipment; third, no matter for the open feeding equipment or the closed feeding equipment, the coating with higher viscosity It is easy to deposit on the bottom of the feeding equipment during the coating process, making flow coating difficult

However, the oil pump needs to drive the stirring shaft to stir the paint in the tank, and there are still some defects: first, the stirring shaft only stirs for a part in the sealed tank body, so that the precipitation of the paint cannot be completely avoided; second, in the sealed tank body When the remaining material is small, stirring with the stirring shaft often cannot achieve a good stirring effect; third, in order to prevent the precipitation of the paint, it is necessary to continuously use a manual crank or an oil pump to drive the stirring shaft to stir the paint in the tank However, stirring for a long time will make the paint in the sealed tank continue to heat up. For paints containing flammable and explosive substances such as methanol, the rise in temperature in the tank will easily cause accidents such as fire or explosion

[0005] To sum up, the closed coating machine in the prior art has the problem of not being able to balance the two aspects of anti-sedimentation and safety in use
