Air-cooled swill treatment grease separation device

Abstract

The invention relates to the technical field of kitchen waste treatment equipment, in particular to an air-cooled swill treatment grease separation device which comprises a separation tank, a stirring shaft, a driving device, scraping strips and a recovery tank, the stirring shaft is mounted on one side of the separation tank, a condensation plate is rotatably arranged at the tail end of the stirring shaft, and the driving device is connected with the stirring shaft; the stirring shaft and the condensation plate are both of a hollow structure, the stirring shaft is connected with external refrigeration equipment, the scraping strip is connected with the separation tank and located on the opposite side of the stirring shaft, the scraping strip is connected with the ultrasonic vibration device, and the recovery tank is connected with the separation tank and located on the same side as the scraping strip; skillful utilization of the characteristics of high saturability and high curing point of fatty acids in swill is adoped, a refrigeration equipment is creatively used for being matched with the condensation plate, so that grease in swill can be rapidly separated, the separated grease does not contain foreign matter such as food residues, additives do not need to be added in the separation process, the swill grease separation device has practical significance and popularization value, and it is expected that good economic benefits can be generated.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment equipment, in particular to an air-cooled swill treatment oil separation device. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment and catering, and it is also increasingly entering the daily life of ordinary people. [0003] Kitchen waste and swill are the focus of attention in the field of sewage treatment. They not only have high oil content, but also have extremely rich types and types of oil. In addition to vegetable oil, they also include high saturated fatty acids from pigs, cattle, sheep and other animals. If it is directly discharged without treatment, the oily substances fl...

Problems solved by technology

[0003] Kitchen waste and swill are the focus of attention in the field of sewage treatment. They not only have high oil content, but also have extremely rich types and types of oil. In addition to vegetable oil, they also include high saturated fatty acids from pigs, cattle, sheep and other animals. If it is directly discharged without treatment, the oily substances float on the water surface and form a thin film, which can prevent the oxygen in the air from dissolving into the water, reduce the dissolved oxygen in the water, cause the plankton in the water body to die due to lack of oxygen, and also hinder the growth of aquatic plants. photosynthesis, thereby affecting the self-purification of water bodies, and even making water bodies smelly, destroying the utilization value of water resources

[0004] Common oil-water separation is mainly based on the different properties of water and oil, using gravity sedimentation or physical and chemical reactions to remove impurities to achieve oil-water separation. However, the composition of swill is very complex, and the types of oil are extremely rich. Using the above method for oil-water separation is extremely troublesome. If it is based on the existing technology, developing a device with a simple structure that can quickly realize the oil-water separation operation of swill will have positive significance for solving the above problems
