Waste rolling oil regeneration device

Abstract

The invention relates to a waste rolling oil regeneration device belonging to the technical field of regeneration device structures. The waste rolling oil regeneration device comprises an oil feeding pump which is connected with a heat exchanger; a flowmeter for metering waste rolling oil is arranged between the oil feeding pump and the heat exchanger; the output end of the heat exchanger is communicated with a thin film distiller for separating rolling oil from heavy oil; the input ends of the heat exchanger and the thin film distiller are circularly communicated with a heat conducting oil furnace; the thin film distiller is connected with a condenser for collecting gas rolling oil; the condenser is connected with a vacuum unit for meeting the vacuum degree required by the thin film distiller and evaporating the rolling oil below a flash point; and the lower end of the thin film distiller is connected with a heavy oil tank for collecting heavy oil which is not evaporated and a finished product oil tank for collecting finished oil. The invention has reasonable structural design and fully protects base oil components of the rolling oil and addictive components from being damaged; and meanwhile, the regeneration efficiency of the waste rolling oil is excessively high and the purity of the regenerated rolling oil is excessively high.

Description

technical field [0001] The invention relates to a regeneration device for waste rolling oil, which belongs to the technical field of regeneration device structure. Background technique [0002] The production of high-quality, high-grade and high-value-added aluminum strip and foil is the pursuit of the development of aluminum enterprises. The quality control of aluminum foil rolling oil is particularly important in the use process, because the use process is inevitably affected by mechanical oil, hydraulic oil, grease, etc. And aluminum metal powder impurities "pollution", replacing the waste rolling oil off the production line as fuel oil incineration, can not be recycled, the first waste of resources, the second increases the cost of enterprises, and the third is when fuel oil incineration pollutes the environment.

[0002] The production of high-quality, high-grade and high-value-added aluminum strip and foil is the pursuit of the development of aluminum enterprises. The quality control of aluminum foil rolling oil is particularly important in the use process, because the use process is inevitably affected by mechanical oil, hydraulic oil, grease, etc. And aluminum metal powder impurities "pollution", replacing the waste rolling oil off the production line as fuel oil incineration, can not be recycled, the first waste of resources, the second increases the cost of the enterprise, and the third is when the fuel oil incineration pollutes the environment

[0003] Aluminum strip and foil rolling oil will inevitably be mixed with a small amount of heavy oil and mechanical impurities during the working process. These impurities will increase the viscosity of the rolling oil and affect the cooling and lubrication effects. The carbon chains of these polymer heavy oil components are continuous It is easy to break at high temperature, causing symptoms such as yellow spots on the aluminum strip and foil. Aluminum rolling companies will consider replacing with new oil immediately
