Description

Technical Field

[0001] This utility model relates to the field of anti-rust paint preparation technology, and in particular to a filtration device for preparing water-based anti-rust paint. Background Technology

[0002] Rust-preventive paint is a coating that protects metal surfaces from chemical or electrochemical corrosion caused by the atmosphere, seawater, etc. It is mainly divided into two categories: physical and chemical rust-preventive paints. The former relies on the proper combination of pigments and paints to form a dense paint film to prevent the penetration of corrosive substances, such as iron oxide red, aluminum powder, and graphite rust-preventive paints; the latter relies on the chemical rust-inhibiting effect of rust-preventive pigments, such as red lead and zinc yellow rust-preventive paints. It is used for rust prevention of metals such as bridges, ships, and pipelines.

[0003] Wastewater is generated during the preparation of anti-rust paint. This wastewater contains oily substances that float on the surface. Current wastewater filtration structures treat the wastewater directly, causing the oily substances to adhere to the filtration device, resulting in a decrease in the filtration effect. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems and deficiencies by proposing a filtration device for the preparation of water-based anti-rust paint: when wastewater accumulates in the tank to the level of the oil pipe, it is detected by a liquid level sensor. The oily substances floating on the surface of the wastewater are discharged from the oil pipe in the tank. The oil pipe and the discharge pipe treat the oily substances in the wastewater separately, which is convenient to use, solves the problem of deterioration in the filtration effect, and facilitates the pretreatment of wastewater.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:
