[0022] like Figures 1-4 As shown, a stirring and mixing device in the refining process of lubricating oil includes a mixing tank 1. The mixing tank 1 is equipped with a stirring assembly for mixing lubricating oil and solvent. The stirring assembly includes a stirring frame 2 rotatably connected to the top surface inside the mixing tank 1. A reciprocating screw 201 is fixed to the bottom surface inside the stirring frame 2. The stirring frame 2 is rotatably connected to the outer wall of the reciprocating screw 201. An extension hole 202 is provided in the middle of the stirring frame 2. A movable frame 203 is linearly slidably provided on the outer wall of the stirring frame 2. A slider 204 is fixed inside the movable frame 203. The slider 204 passes through the extension hole 202 and is threadedly connected to the outer wall of the reciprocating screw 201.

[0023] like Figures 2-4As shown, in this embodiment, a reduction motor 205 is fixed to the top surface of the mixing tank 1. The output shaft of the reduction motor 205 is fixed to the top of the stirring frame 2. By starting the reduction motor 205, the stirring frame 2 is rotated to mix the lubricating oil and solvent inside the mixing tank 1. When the stirring frame 2 rotates, it will drive the movable frame 203 to rotate together, so that the movable frame 203 drives the slider 204 to rotate on the outer wall of the reciprocating screw 201. The slider 204 is threadedly connected to the outer wall of the reciprocating screw 201, so that the slider 204 drives the movable frame 203 to move up and down. The movable frame 203 moves up and down reciprocally inside the mixing tank 1 while rotating with the stirring frame 2, which increases the mixing effect of the lubricating oil and solvent. Moreover, the stirring frame 2 is not affected by the rotation speed of the stirring frame 2, which increases the reliability of the device.

[0024] like Figures 2-4 As shown, in this embodiment, a circulating impeller 3 is fixed on the bottom surface of the stirring rack 2. The circulating impeller 3 has a gap with the inner bottom surface of the mixing tank 1. When the movable frame 203 rotates, it also drives the circulating impeller 3 to rotate. The rotation of the circulating impeller 3 causes the mixture inside the mixing tank 1 to flow continuously to the bottom of the mixing tank 1 and leads the upper layer of the mixture to the lower layer, thereby increasing the mixing effect of the lubricating oil and solvent.

[0025] like Figures 2-4 As shown in this embodiment, inclined plates 4 are fixed on both the front and rear sides of the stirring rack 2. The inclined plates 4 are inclined towards the middle of the mixing tank 1. When the movable frame 203 rotates, it also drives the inclined plates 4 to rotate. Since the inclined plates 4 are inclined towards the middle of the mixing tank 1, the mixture is led along the inclined surface of the inclined plates 4 to the middle position of the mixing tank 1, so that the outer layer of the mixture is continuously led to the inner layer, further increasing the mixing effect of lubricating oil and solvent.

[0026] like Figures 2-4 As shown, in this embodiment, the top surface of the mixing tank 1 is connected to and fixed with two feeding pipes 5, and the bottom surface of the mixing tank 1 is connected to and fixed with a discharge valve 501. The inner bottom surface of the mixing tank 1 is a sloping structure, and the lowest point of the inner bottom surface of the mixing tank 1 is located at the discharge valve 501. Lubricating oil and solvent are added into the mixing tank 1 from the two feeding pipes 5 in a certain proportion. After the lubricating oil is mixed, the mixed lubricating oil can be discharged by opening the discharge valve 501.

[0027] like Figures 2-4 As shown, in this embodiment, the top and bottom ends of the movable frame 203 are both fixed with a first sealing ring, which abuts against the outer wall of the stirring frame 2. The inner wall of the circulating impeller 3 is fixed with a second sealing ring, which abuts against the non-threaded outer wall of the reciprocating screw 201. By setting the first sealing ring and the second sealing ring, lubricating oil can be prevented from entering the reciprocating screw 201 and affecting its use.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, when refining lubricating oil, lubricating oil and solvent are respectively added into the mixing tank 1 from two feeding pipes 5 in a certain proportion. Then, the reduction motor 205 is started to drive the stirring frame 2 to rotate and mix the lubricating oil and solvent in the mixing tank 1. When the stirring frame 2 rotates, it will drive the movable frame 203 to rotate together, so that the movable frame 203 drives the slider 204 to rotate on the outer wall of the reciprocating screw 201. The slider 204 is threadedly connected to the outer wall of the reciprocating screw 201, so that the slider 204 drives the movable frame 203 to move up and down, so that the movable frame 203 moves up and down with the stirring frame 2. The stirring rack 203 moves back and forth inside the mixing tank 1, increasing the mixing effect of lubricating oil and solvent. The stirring rack 2 is not affected by the rotation speed of the stirring rack 2, which increases the reliability of the device. At the same time, the moving rack 203 also drives the circulating impeller 3 and the inclined plate 4 to rotate. The rotation of the circulating impeller 3 causes the mixture inside the mixing tank 1 to flow continuously to the bottom of the mixing tank 1 and to guide the upper layer of the mixture to the lower layer, which increases the mixing effect of lubricating oil and solvent. When the two inclined plates 4 rotate, since the inclined plates 4 are inclined towards the middle of the mixing tank 1, the mixture is guided along the inclined surface of the inclined plate 4 to the middle position of the mixing tank 1, so that the outer layer of the mixture is continuously guided to the inner layer, which further increases the mixing effect of lubricating oil and solvent.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
