Oil-water separator for catering

Abstract

An embodiment of the invention discloses an oil-water separator for catering. The oil-water separator comprises a separator box body, wherein a dreg separation chamber is fixedly installed in the separator box body; a servo motor is fixedly installed at the top of the dreg separation chamber; the output end of the servo motor extends into the dreg separation chamber and is fixedly connected with aspiral blade; the top of the dreg separation chamber fixedly communicates with a water inlet; and the top of the water inlet fixedly communicates with a liquid induction communicating vessel. According to the oil-water separator for catering, the dreg separation chamber, the spiral blade and a dreg outlet are cooperated with each other, so dreg in catering wastewater entering from the water inletis lifted and discharged, a filter residue basket can be prevented from being blocked when the filter residue basket is adopted; meanwhile, emulsified oil in water can react with small holes in the dreg separation chamber, and then demulsification operation is conducted, so the emulsified oil attached to dreg is subjected to demulsification and then separated from the dreg, and oil removal treatment does not need to be conducted on the dreg in a later period.

Description

Technical field [0001] This application relates to the field of catering devices, and more specifically, to an oil-water separator for catering. Background technique [0002] The oil-water separator is a device, divided into two types of catering oil-water separator and industrial oil-water separator. The catering oil-water separator is used for sewage treatment in the catering industry; because of environmental protection requirements, it is discharged into rivers, lakes and seas, ship machinery premises The generated sewage must be treated and an industrial oil-water separator is required. [0003] The currently used catering oil-water separators generally use different densities of oil and water. The oil floats on top of the water, and the oil is scraped out by an oil scraper, but the oil that can float on the water surface is demulsified. However, there is still a lot of emulsified oil remaining in the water and cannot float above the water. Current oil-water separators genera...

AI Technical Summary

Problems solved by technology

[0003] When the currently used catering oil-water separator is in use, the density of oil and water is generally different, the oil floats above the water, and the oil is scraped out by the oil scraping device, but the oil that can float on the water is demulsified However, there is still a lot of emulsified oil remaining in the water, which cannot float above the water. The current oil-water separator generally uses heating and air flotation to break the emulsion, so that the oil after the emulsion can reach the water. Above, and then scraped off, although this can be demulsified, but it cannot completely remove the emulsified oil in the water

[0004] The current oil-water separator uses a filter residue basket to filter out the residue in the water when filtering the residue. The residue adheres to the surface of the filter residue basket, which will easily lead to poor water inlet effect, and will cause a large amount of oil to adhere to the residue. It is troublesome to handle, especially some emulsified oils
