Description

Floating type liquid collecting device

Technical Field

The utility model relates to a liquid separation, in particular to float formula liquid collection device.

Background

The cutting fluid is a metal working fluid used for cooling and lubricating metal in cutting, grinding and other processes. They are of various kinds and complicated in composition, and usually contain a base oil, an emulsifier, a rust preventive, and the like. Cutting fluids (mainly water-based cutting fluids) often have problems of miscellaneous oil, particles and the like in use. The miscellaneous oil is mainly brought by a workpiece or caused by leakage of hydraulic oil of a machine tool and oil of a guide rail. The traditional machine tool is operated by self-carrying oil-water separation, the oil in the used cutting fluid is separated out by utilizing a steel strip oil remover, but the treatment speed is low and the effect is limited, so that a thick oil layer floats on the surface of the liquid, and the performance of the cutting fluid is influenced by breeding microorganisms for a long time.

The release agent is an essential auxiliary material in the die-casting production, in the die-casting production process, in order to prolong the service life of a die cavity and enable the die-casting piece to be smoothly demoulded, the surface of the die-casting piece is smooth and clean, the outline is clear and complete, the release agent is required to be sprayed on the die, a large amount of release agent is sprayed on the die in the die-casting production, part of the release agent is evaporated at high temperature and is adsorbed on the die for consumption, and most of the release agent directly flows into the lower part of the die after being used once to become oil-containing waste liquid, and the oil-containing waste liquid is generally collected.

The degreasing process is a basic process of an automobile coating pretreatment process, and after a white automobile body is welded, a lot of dirty oil including cooling oil, stretch-proofing oil, antirust oil and the like exists on the inner surface, the outer surface and the inner cavity of the automobile body. Problems occur in the degreasing process, which can affect the quality of the electrophoretic paint and further affect the adhesive force and corrosion resistance of the paint film. Along with the increasing of the vehicle passing amount on a production line, the oil content of degreasing fluid is increased, an electrophoresis tank which is not cleaned by dirty oil treatment is polluted, and even a coating workshop stops production and stops working, so that the degreasing tank fluid needs to be taken out for oil-water separation operation.

The purification and reuse treatment of the cutting fluid, the release agent and the degreasing agent can save the production and processing cost on one hand, and can reduce the discharge amount of dangerous wastes on the other hand, thereby realizing green and clean production. The first problem of recycling treatment is to take out the waste liquid to be treated. Generally, the surface layer liquid is taken out, the taken-out liquid is treated to remove substances such as miscellaneous oil, impurities and the like in the surface layer liquid, and the treated cutting fluid and the release agent are returned to be continuously used for production. At present, a floating ball oil suction port is commonly connected with a pump to suck surface liquid, a floating ball always floats on the liquid level, the height of the oil suction port can be adjusted through a bolt on the floating ball, the pump is sometimes directly used for connecting a pipeline to suck the liquid and then carry out subsequent treatment, and particles at the bottom level of the pool are generally manually scraped.

When taking out the top layer liquid, adopt the mode extraction top layer liquid of the direct suction of pump, the liquid level position is too shallow put into to the liquid taking pipe, can't take out the miscellaneous oil in top layer totally, and the position is too dark not only extracts except that the unnecessary liquid of oil, increases subsequent handling capacity, in sucking the sedimentary granule in waste liquid bottom the pump in addition, causes the pump to damage. When the floating ball oil suction port sucks surface liquid, although the height of the oil suction port can be adjusted through the adjusting bolt, the adjusting precision is not high, and the liquid taking effect is not ideal.
