Paint coating device

Abstract

The invention provides a paint coating device. The paint coating device comprises a paint tank, a piston, a piston handle, a spraying nozzle and a high-pressure fluid pump, wherein a cavity of the paint tank is filled with paint, a paint outlet is formed in the top end of the paint tank, the piston is arranged inside the paint tank in a vertical sliding mode, the piston handle extends into the paint tank from a top plate of the paint tank, the bottom end of the piston handle is fixedly connected with the piston, the piston handle is provided with a ventilation hole communicated between the outside and a lower cavity, the spraying nozzle is arranged at one side of the paint tank and provided with a fluid passage, an outlet of the fluid passage is located above the paint outlet, the high-pressure fluid pump is used for guiding high-pressure fluid into the fluid passage, and an outlet of the high-pressure fluid pump is communicated with an inlet of the fluid passage. Pressure difference is generated between the cavity, filled with the paint, of the paint tank and the outside, the paint inside the paint tank is automatically pressed into the paint outlet based on the siphon principle, and then automatic coating is achieved. The paint coating device can be applied to coating of paint with different viscosities, and therefore the paint coating device can replace manual coating, is used for coating anti-corrosion paint or fire retardant or the like with high viscosity, and improves coating efficiency.

Description

technical field [0001] The invention relates to the technical field of electric power system anticorrosion, and more specifically, relates to a paint spraying device. Background technique [0002] In the power system, the anti-corrosion work of power cables and other power equipment is a necessary condition to ensure safe operation. At present, most occasions mainly use spraying machines to spray anti-corrosion coatings for daily anti-corrosion work. [0003] A traditional spraying machine includes a paint tank with a pressurized cabin and a booster pump for pressurizing the paint. The spraying machine mainly generates atomization by pressurizing the paint in the tank, and then sprays the paint. The spraying machine sprays out The coating is relatively uniform, and it can avoid a large amount of paint spilling. However, because the paint with high viscosity cannot be atomized, the above-mentioned spraying machine can only spray low-viscosity paint, and cannot be applied to...

AI Technical Summary

Problems solved by technology

However, because the paint with high viscosity cannot be atomized, the above-mentioned spraying machine can only spray low-viscosity paint, and cannot be applied to high-viscosity anti-corrosion paint and flame retardant coatings, so it can only be manually painted with high viscosity. paint, less efficient

[0004] In addition, the booster pump of the spraying machine and the paint tank are of an airtight integrated structure, which makes it difficult to clean and maintain the paint tank, and it is necessary to pick up the entire spraying machine when spraying, which takes up a large operating space and is not suitable for power system towers. Anti-corrosion spraying of equipment with small operating space such as equipment and equipment components
