Technical Field
[0001] This utility model relates to the field of white oil treatment technology, specifically to a white oil refining tank. Background Technology
[0002] Existing white oil refining tanks often add white oil and bleaching clay separately, which may result in insufficient mass transfer efficiency. During the white oil refining process, the mass transfer effect of the mixture of bleaching clay and white oil affects the refining efficiency. In some traditional white oil refining tanks, the stirring device may not be able to achieve an ideal mixing state between the bleaching clay and white oil, causing the bleaching clay to not fully perform its function of adsorbing impurities, and some white oil to fail to effectively contact the bleaching clay, thus reducing the refining effect.

Multiple sets of anchor-type stirring paddles are evenly arranged on the mixing shaft. The bottom of the refining tank has a conical structure. A white oil discharge port with a filter screen and a valve is located at the bottom of the refining tank. The white oil discharge port is connected to the inlet of the bag filter through a white oil discharge pipe.
[0007] Preferably, the top of the refined tank is also provided with a breather valve for balancing the pressure inside the tank.
[0008] Preferably, the number of multiple sets of anchor-type agitators is no less than four sets.
[0009] Preferably, each set of anchor-type mixing paddles includes four upward-sloping mixing rods evenly arranged along the circumference of the mixing shaft, with the mixing rods forming an angle of 60° with the mixing shaft.
[0010] Preferably, the bottom of the refining tank and the side of the white oil discharge port are provided with a white clay intake port.

[0021] As shown in the attached figure, a white oil refining tank includes a refining tank body 1, a combined mixing mechanism disposed in front of the refining tank body 1, and a bag filter 2 disposed behind the refining tank body 1.
[0022] The combined mixing mechanism includes a turbine dynamic pipeline mixer 3 and an SK-type static mixer 4, which are installed on the top of the refining tank 1 and connected in sequence. The two inlet ends of the turbine dynamic pipeline mixer 3 are respectively connected to the white oil conveying pipe and the white clay inlet pipe. The outlet end of the turbine dynamic pipeline mixer 3 is connected to the inlet end of the SK-type static mixer 4. The outlet end of the SK-type static mixer 4 is connected to the inlet 5 of the refining tank 1 through a right-angle bend 6.
[0023] A mixing motor 8 is located at the top center of the refining tank 1. The output shaft of the mixing motor 8 is connected to a mixing shaft 9 extending into the refining tank 1. Multiple sets of anchor-type stirring paddles 10 are evenly arranged on the mixing shaft 9. The bottom of the refining tank 1 has a conical structure and a white oil discharge port 11 with a filter screen and valve. The white oil discharge port 11 is connected to the inlet of the bag filter 2 through a white oil discharge pipe 12. Regular monitoring, cleaning, or replacement of the filter bags is necessary to ensure filtration efficiency and flow rate.
[0024] In another technical solution, the top of the refined tank 1 is also provided with a breather valve 7 for balancing the pressure inside the tank to prevent the pressure from being too high or too low.
[0025] In another technical solution, the number of multiple sets of anchor-type stirring paddles 10 is no less than four sets to ensure the stirring effect and improve the mass transfer efficiency.
[0026] In another technical solution, each set of anchor-type mixing paddles 10 includes four inclined upward mixing rods 13 evenly arranged around the mixing shaft 9, with the mixing rods 13 having an angle of 60° with the mixing shaft 9.
[0027] In another technical solution, a clay intake port 14 is provided at the bottom of the refining tank 1 and on one side of the white oil discharge port 11. The height of the side intake port is generally about 0.5-1m from the bottom of the tank, and the angle is usually 30-60° with the tangent of the tank body, so that the clay can be easily extracted.
[0028] In another technical solution, the filter screen at the white oil discharge port 11 is a high-strength stainless steel filter screen to prevent the outflow of bleaching clay particles. This filters solid impurities in the white oil, such as bleaching clay particles and rust, preventing these impurities from flowing out with the white oil and affecting its quality and subsequent use. The filter screen also provides preliminary filtration assurance for subsequent fine filtration processes, helping to improve the efficiency and stability of the entire filtration system.
[0029] In another technical solution, the side wall of the refined tank 1 is also provided with a heating jacket 15 and a heat insulation layer 16. The heat insulation layer effectively reduces heat loss and lowers energy consumption.
[0030] Working principle: A combined mixing mechanism is set in front of the refining tank. White oil and white clay are first mixed by a turbine dynamic pipeline mixer and then enter the SK-type static mixer. The combined mixing mechanism can effectively improve the mass transfer efficiency of white oil and white clay. Then, they are mixed and stirred by multiple sets of anchor-type stirring paddles in the refining tank to ensure the refining effect of white oil.
