Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil storage, in particular to a storage tank for lubricating oil production. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It is generally composed of two parts: base oil and additives. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil needs to be stored in storage tanks during the production process. However, during long-term storage, a large amount of sediment will be deposited at the bottom of the storage tank. However, it is not convenient to clean the sediment at the bottom of the existing storage tank when it is used, which leads to a large amount of sediment being mixed with the lubricating oil, affecting the use effect of the lubricating oil.

[0003] After searching, it is found that the lubricating oil production storage tank in the prior art is typically such as a lubricating grease production storage tank disclosed in publication number CN217436689U, including a lubricating oil storage tank, a sealing cover is fixedly provided on the left end of the lubricating oil storage tank by a fixing mechanism, a sealing ring is provided between the left side wall of the lubricating oil storage tank and the sealing cover, an oil inlet pipe is fixedly provided on the upper side wall of the lubricating oil storage tank, an oil outlet pipe is fixedly provided on the lower side wall of the lubricating oil storage tank, a motor is fixedly provided on the right side wall of the lubricating oil storage tank by a fixing frame, a bracket is fixedly provided laterally inside the lubricating oil storage tank, a screw rod is rotatably provided at the lower end of the bracket, and the right end of the screw rod is fixedly connected to the output end of the motor, so that when a large amount of precipitation is generated after the lubricating oil storage tank has stored the lubricating grease for a long time, the sealing cover can be quickly opened, and the precipitation at the bottom of the lubricating oil storage tank can be processed by a scraper to prevent the precipitation from mixing with the lubricating grease again and affecting the use effect of the lubricating grease.

[0004] In the prior art, when cleaning the sediment at the bottom of the storage tank, the lubricating oil inside the lubricating oil storage tank needs to be emptied, and then the sealing cover needs to be opened to remove the sediment from the lubricating oil storage tank. The operation is relatively cumbersome. Therefore, we propose a storage tank for lubricating oil production. Utility Model Content
