Used lubricating oil recycling device

Abstract

The invention discloses a used lubricating oil recycling device. The device comprises a tank, wherein a first motor is mounted above the tank, a stirring rod is connected to an output end of the firstmotor, a casing is welded to the outer side of the tank in a sealed manner, a vacuum layer is arranged between the casing and the tank, a filter box is connected below the tank, a support plate is welded fixedly above the filter box, openings are formed in the support plate, a bearing block is fixedly connected to the middle above the support plate, an emptying port is connected below the conicalfilter box, the filter box is connected with an oil outlet in one side of the emptying port, the other end of the oil outlet is connected with an intermediate box through a connecting pipe, the otherside of the intermediate box is connected with a film evaporator through a pipeline, and one side of the film evaporator is connected with an oil storage tank. The used lubricating oil recycling device is reasonable in design, recycling of used lubricating oil is convenient to realize, and the device is worth spreading.

Description

technical field [0001] The invention relates to the technical field of waste lubricating oil recycling devices, in particular to a waste lubricating oil recycling device. Background technique [0002] China's lubricating oil production accounts for about 2% of the total petroleum products, and the amount is more than 3 million barrels per year. Lubricating oil will gradually age and deteriorate due to high temperature and air oxidation during use, coupled with metal powder from friction parts, moisture entering the oil due to respiration and other reasons, and impurities intruding from the environment , These not only pollute the lubricating oil, but also promote the oxidation of the lubricating oil, which may cause various failures of the machine. Therefore, the lubricating oil must be replaced after it has been used for a certain period of time and has deteriorated to a certain extent. Many lubricating oils are added with heavy metal salt additives, and some are added wit...

Problems solved by technology

Lubricating oil will gradually age and deteriorate due to high temperature and air oxidation during use, coupled with metal powder from friction parts, moisture entering the oil due to respiration and other reasons, and impurities intruding from the environment , These not only pollute the lubricating oil, but also promote the oxidation of the lubricating oil, which may cause various failures of the machine. Therefore, the lubricating oil must be replaced after it has been used for a certain period of time and has deteriorated to a certain extent. Many lubricating oils are added with heavy metal salt additives, and some are added with chlorine-containing organic compounds, sulfur-containing organic compounds, phosphorus-containing organic compounds, sulfur- and phosphorus-containing organic compounds, and some chlorine-containing compounds are more Chlorine substitutes for aromatic hydrocarbons. These compounds containing heavy metals, sulfur, phosphorus, and chlorine are toxic substances, harmful to humans and organisms, and may harm humans through various channels. Oil entering the water system has a strong pollution effect on water. , therefore, it is necessary to invent a waste lubricating oil recycling device to solve the above problems
