A multi-stage filter grease trap

Abstract

The invention relates to the technical field of oil separators, in particular to a multi-stage filtration oil separator, comprising a pool body, a separation mechanism is arranged in the pool body, a screening mechanism is arranged in the pool body, and the screening mechanism There is a scraping mechanism on it, a flushing mechanism is arranged in the tank body, a cleaning mechanism is arranged on the separating mechanism, an adjusting mechanism is arranged on the separating mechanism, and an oil scraping mechanism is arranged on the tank body; The cooperation between the mechanism and the sweeping mechanism can better handle the solid waste in the sewage, avoid the blockage of the basket net by the solid waste, and improve the treatment effect of the sewage; The height of the tank can be adjusted, which is convenient for the treatment of different types of swill; the oil scraping mechanism is located inside the tank body, which is convenient to push and scrape the oil floating on the surface, so that the oil can be discharged more smoothly, and it is also convenient for Scrape off the oil stains on the inner wall of the equipment to reduce the generation of odors.

Description

technical field [0001] The invention relates to the technical field of oil separators, in particular to a multi-stage filtering oil separator. Background technique [0002] The grease trap is a wastewater pretreatment structure that uses the density difference between oil droplets and water to generate floating action to remove buoyant oil substances in oily wastewater. The structure of the oil separator is mostly advection. The oily wastewater enters the rectangular oil separator through the water distribution tank, and flows slowly in the horizontal direction. During the flow, the oil floats on the water surface and flows into the dehydration tank from the oil collecting pipe. In some catering establishments, grease traps are often required. [0003] However, in the actual operation of the traditional grease trap, since the kitchen sewage is not only a mixture of oil and water, but also inevitably contains some solid wastes with large particles, such as vegetable leaves a...

[0003] However, in the actual operation of the traditional grease trap, since the kitchen sewage is not only a mixture of oil and water, but also inevitably contains some large-particle solid waste, such as vegetable leaves and bones, etc., it is necessary to use the corresponding basket However, in the long-term use process, these solid wastes will continue to accumulate, causing blockage of the basket, seriously affecting the sewage treatment effect and work efficiency; at the same time, in the actual oil discharge process, only rely on the effect of gravity , the oil floating on the upper layer is difficult to discharge completely, resulting in low oil discharge efficiency, and a large amount of oil will inevitably adhere to the inner wall of the oil separation area. If it is not cleaned, after a long period of use , not only will aggravate the corrosion damage to the equipment, but will also produce a very unpleasant smell; in addition, for different types of swill, the density of the internal oil will also vary, so there will be some differences in the situation of oil floating. The traditional fixed oil separator is not convenient to apply to various situations
