Description

TECHNICAL FIELD

[0001] The utility model relates to lubricating oil decoloring technical field, especially a kind of industrial lubricating oil decoloring filter core. BACKGROUND

[0002] The common decoloring method of lubricating oil is adsorption method, mainly using silica gel sand, clay and other substances with strong adsorption capacity as decoloring agent, using the porous structure and surface chemical substances of decoloring agent to remove the pigment and other impurities in lubricating oil, so as to achieve the effect of decoloring. After decoloring, the particulate matter, suspended matter, color impurities and other impurities in the oil can be removed, and the purity of the oil can be improved.

[0003] The traditional industrial lubricating oil decoloring tank has an inlet at the upper end of the side wall and an outlet at the lower end, and a cover plate is arranged in the tank to compact silica gel sand and prevent lubricating oil from flowing unevenly. The lubricating oil enters the decoloring tank from the upper end pipe at the top, flows through the silica gel sand in the decoloring tank, and then flows out from the lower end pipe after decoloring. The traditional industrial lubricating oil decoloring tank is generally large in size, and a large amount of silica gel sand in the tank body needs to be filled and discharged manually during replacement, i.e. the workers need to use an iron shovel to shovel out the silica gel sand in the tank body from the lower end outlet during replacement, and then fill new silica gel sand from the upper end inlet for reuse. In addition, manual compaction and cover plate installation are required, which is time-consuming and labor-intensive and very inconvenient.

[0004] In addition, the sand layer and the pipe are often blocked by dirt during use, which increases the difficulty and cost of cleaning and maintenance.

[0005] Therefore, in view of the above-mentioned deficiencies in actual production and implementation, the industrial lubricating oil decoloring filter core is modified and improved, and the spirit and concept of seeking good results are followed, and the knowledge and experience of professionals are assisted, and after careful consideration and testing, the industrial lubricating oil decoloring filter core is provided to solve the technical problems of inconvenient replacement of silica gel sand in the traditional decoloring tank and time-consuming and labor-intensive.
