Technical Field

[0001] The utility model relates to the technical field of lubricating oil production equipment, in particular to a white clay adsorber for lubricating oil base oil. Background Art

[0002] Lubricating oil is one of the important petrochemical products, with a wide variety of products, widely used in production and life. The raw materials for lubricating oil production usually include base oil and various additives, among which base oil is the main component of lubricating oil, usually paraffin oil, wax base oil, viscosity index improver, etc. produced from cracking plants or refineries. Base oil needs to go through several steps of treatment such as impurity removal, decolorization and deodorization during the production process.

[0003] The production of lubricating oil base oil basically adopts physical methods, that is, the "old three sets" of traditional processes consisting of solvent refining, solvent dewaxing and clay supplementary refining to produce lubricating oil base oil. Clay supplementary refining is to fully mix the oil and clay at a certain temperature, and use the adsorption properties of the surface of activated clay to remove nitrides, colloids, asphaltene, cyclohexane acid soaps, unsaturated hydrocarbons, selective solvents, moisture, mechanical impurities, etc. in the lubricating oil, thereby improving the color of the oil, reducing residual carbon, and improving the anti-oxidation stability and anti-emulsification degree of the oil.

[0004] However, during the clay refining process, since it is impossible to determine the amount of lubricant base oil and the ratio of clay, the clay is directly introduced into the lubricant base oil mixing barrel for adsorption during the refining process, resulting in a large amount of clay waste. At the same time, it cannot ensure that the clay is in full contact with the base oil and lubricant for adsorption, affecting the adsorption effect. Utility Model Content

A stirring component for mixing the lubricating oil base oil and the kaolin is installed inside the mixing tank 1. The top of the mixing tank 1 is connected to the oil inlet pipe 5. The mixing tank 1 is connected to the kaolin storage box through the feed pipe 6. A discharge port 9 is provided at the bottom of the mixing tank 1, and the discharge port 9 is connected to the evaporator through the discharge pipe.

[0018] The feed pipe 6 includes a first branch pipe 7 and a second branch pipe 8. The first branch pipe 7 is connected to the top of the mixing tank 1, and the other end of the second branch pipe 8 is connected to a drying box for drying the clay.

[0019] A humidity sensor 11 for detecting the humidity of the clay is arranged on the main pipe of the feed pipe 6, and the output end of the humidity sensor is connected to the input end of the controller.

[0020] A first solenoid valve 13 is provided on the first branch pipe 7 close to the main pipe of the feed pipe 6. The controlled end of the first solenoid valve 13 is connected to the output end of the controller and can be opened and closed under the action of the controller.

[0021] A second flow meter 12 is also provided on the first branch pipe 7. The output end of the second flow meter 12 is connected to the input end of the controller, and can detect the flow of the white clay entering the mixing tank 1. In case of insufficient flow, the controller can be used to feed back to the drying box for adjustment.

[0022] A second solenoid valve 14 is provided on the second branch pipe 8 close to the main pipe of the feed pipe 6 , and a controlled end of the second solenoid valve 14 is connected to the output end of the controller.

[0023] A first flow meter 10 is provided on the oil inlet pipe 5, and the output end of the first flow meter 10 is connected to the input end of the controller, so as to detect the flow of the lubricating base oil entering the mixing tank 1 and control the flow of the clay through the controller.

[0024] The stirring assembly includes a rotating shaft 2 installed inside a mixing tank 1 , and spiral stirring blades 3 are arranged on the circumference of the rotating shaft 2 , which can fully stir the lubricating oil base oil and the clay and transport them to the discharge port 9 .

[0025] The rotating shaft 2 is driven by a motor 4 arranged on the top of the mixing tank 1, and the controlled end of the motor is connected to the output end of the controller.

[0026] A valve is arranged on the discharge pipe at the discharge port, and a controlled end of the valve is connected to an output end of the controller.

[0027] The operation mode and principle of the utility model are as follows:

[0028] Firstly, the lubricating oil base oil is controlled to enter the mixing tank 1 through the oil inlet pipe 5, and at the same time, the white clay is controlled to enter the mixing tank 1 through the feed pipe 6 and the first branch pipe 7.

[0029] When the first flowmeter 10 on the oil inlet pipe 5 detects the flow of the lubricating base oil and feeds back to the controller, the controller will control the clay storage tank to adjust the flow of the clay in a suitable ratio to ensure that the lubricating base oil and the clay can be fully mixed.

[0030] Then, the motor is started to drive the rotating shaft 2 to rotate, and the lubricating oil base oil and the white clay are mixed and stirred by the spiral stirring blades 3.

[0031] Finally, after stirring for a suitable period of time, the mixed lubricating oil base oil flows out from the discharge port through the discharge pipe into the evaporator.

[0032] The humidity sensor 11 arranged on the feed pipe 6 can detect the humidity of the clay. If the humidity meets the requirements, the first solenoid valve 13 is controlled to open and the clay flows into the mixing tank 1; if the conditions are not met, the second solenoid valve 14 is controlled to open, and the clay flows into the drying box through the second branch pipe 8 for drying, and then enters the mixing tank 1 through the feed pipe 6 for use.
