Description

Technical Field

[0001] The utility model belongs to the technical field of waste oil treatment, in particular to waste oil impurity removal treatment equipment. Background Art

[0002] The waste cooking oil extracted from the greasy floating materials in the sewer or the leftovers in hotels and restaurants after simple processing is a recyclable resource. It can be turned into treasure after chemical and physical transformation and physical refining.

[0003] At present, a Chinese utility model with publication number: CN216909404U discloses a waste oil pre-impurity removal treatment device, including a pretreatment box, an inlet is opened at the upper left end of the pretreatment box, the inlet is adapted with a sealing cover, two tracks distributed up and down are arranged inside the pretreatment box, the right side is sealed and connected to a telescopic extrusion device, and the lower end is fixedly connected to a filtering and collecting device. The whole device has good pretreatment effect, no odor, protects the environment, has strong corrosion resistance, and has a high safety factor.

[0004] The existing waste oil contains a large amount of impurities. After filtering it, the solid matter can be filtered out. However, since the solid matter is immersed in the waste oil for a long time, it absorbs a large amount of waste oil. The common waste oil impurity removal processing equipment cannot squeeze out the solid matter and squeeze out the residual waste oil after filtering and removing the waste oil, so part of the waste oil will be wasted, and the practicality is low. At the same time, since the waste oil also contains a large amount of water, the oil will be suspended on the water. When the waste oil is separated from the water, the oil drain pipe cannot change freely with the height of the oil level after the oil is discharged. The height of the oil level is reduced after the discharge, which will cause the amount of oil discharged from the oil drain pipe to decrease. Therefore, it is necessary to ensure that the oil level inside the container is at a certain height, which in turn affects the amount of oil discharged, resulting in low waste oil treatment efficiency. Utility Model Content

[0005] The utility model aims to provide a waste oil impurity removal processing device, which has the advantages of being able to squeeze the residual waste oil from the solid matter filtered out and the oil discharge pipe changing with the height of the oil level to ensure the efficiency of oil discharge.
