DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As Figure 1 - Figure 3As shown in the figure, a waste lubricating oil treatment and decolorization device includes a cylinder body 1. The top wall of the cylinder body 1 is a detachable cylinder cover structure. A motor 2 is provided in the middle of the top wall of the cylinder body 1. The output end of the motor 2 is provided with a transmission shaft 7. The lower end of the transmission shaft 7 extends into the cylinder body 1. A first stirring assembly 8 is provided in the middle of the outer surface of the transmission shaft 7. A second stirring assembly 9 is provided in the lower part of the outer surface of the transmission shaft 7. A sampling mechanism 5 for checking the decolorization of the oil liquid is provided on the left side of the lower part of the outer surface of the cylinder body 1. A discharge pipe 3 communicating with the inner cavity of the cylinder body 1 is provided on the right side of the lower part of the outer surface of the cylinder body 1. A wavy annular groove 6 is opened on the outer side of the inner top wall of the cylinder body 1. A steering mechanism 4 for controlling the first stirring assembly 8 and the second stirring assembly 9 to rotate in opposite directions is provided in the middle of the lower end of the cylinder body 1. Four legs are provided on the outer side of the lower end of the cylinder body 1;

[0026] It can be seen from this that after pouring the waste lubricating oil and the clay for decolorization into the cylinder body 1, the motor 2 then controls the first stirring assembly 8 and the second stirring assembly 9 to rotate together through the transmission shaft 7. Then, under the action of the steering mechanism 4, the first stirring assembly 8 and the second stirring assembly 9 rotate in opposite directions to improve the mixing effect of the waste lubricating oil and the clay. After that, first check the decolorization of the waste lubricating oil through the sampling mechanism 5, and finally discharge the oil liquid through the discharge pipe 3.

[0027] Specifically, as Figure 4 shown, the sampling mechanism 5 includes an observation tube 51 fixedly connected to the left side of the lower part of the outer surface of the cylinder body 1, and the observation tube 51 is communicated with the inner cavity of the cylinder body 1. The observation tube 51 is made of transparent glass to facilitate viewing the appearance of the waste lubricating oil and judging whether it can be taken out for the next treatment. A piston plate 52 is provided inside the observation tube 51. A screw rod 53 is provided in the middle of the left end of the piston plate 52. The left end of the screw rod 53 extends to the outside of the observation tube 51 and is provided with a turntable. A filter screen frame 54 for intercepting the clay is provided in the right part of the inner side of the observation tube 51 to prevent the clay from flowing into the observation tube 51 together with the oil liquid and affecting the viewing of the appearance of the oil liquid. The right end of the filter screen frame 54 is located on the same curved surface as the inner wall of the cylinder body 1 to avoid affecting the rotation of the second stirring assembly 9;

[0028] It can be seen from this that when it is necessary to check the decolorization of the oil liquid, rotate the turntable to control the screw rod 53 and the piston plate 52 to rotate and move outwards. Then, while the oil liquid in the cylinder body 1 freely flows into the observation tube 51, the clay mixed in the oil liquid will also be intercepted by the filter screen frame 54, so as to facilitate the staff to check the decolorization of the oil liquid. If it is unqualified, rotate the turntable in the reverse direction to push the piston plate 52 back to the initial position, thereby pushing the oil liquid back into the cylinder body 1 for decolorization.

[0029] Specifically, as Figure 3 shown, the first stirring assembly 8 includes two groups of triangular connecting pipe groups, and the two groups of triangular connecting pipe groups are respectively fixedly connected to the middle upper part and the middle lower part of the outer surface of the transmission shaft 7;

[0030] Specifically, the triangular connecting pipe group is composed of three positioning pipes 81, and the three positioning pipes 81 are distributed in a circular array. F-shaped stirring rods 82 are jointly arranged inside two positioning pipes 81 located in the same vertical direction. Here, it refers to two positioning pipes 81 in the same vertical plane among two triangular connecting pipe groups. The horizontal part of the F-shaped stirring rod 82 is slidably connected inside the positioning pipe 81, and the vertical part of the F-shaped stirring rod 82 extends upward and is slidably connected inside the wavy annular groove 6. Stirring blades I 83 are arranged on both the side of the vertical part of the F-shaped stirring rod 82 close to the transmission shaft 7 and the side far from the transmission shaft 7, and the stirring blades I 83 are located between the two horizontal parts of the F-shaped stirring rod 82;

[0031] It can be seen from this that when the motor 2 controls the rotation of the first stirring assembly 8 through the transmission shaft 7, the vertical part of the F-shaped stirring rod 82 will also slide inside the wavy annular groove 6 to make the horizontal part of the F-shaped stirring rod 82 continuously enter and exit the positioning pipe 81, so as to change the stirring range of the stirring blades I 83 and disturb the oil liquid to avoid uneven distribution of clay.

[0032] Specifically, as Figure 3 shown, the second stirring assembly 9 includes a rotating pipe 91. The rotating pipe 91 is sleeved on the outer surface of the bottom of the transmission shaft 7 and is rotatably connected to the transmission shaft 7. Four stirring blades II 92 are evenly arranged on the outer surface of the rotating pipe 91, and the ends of the stirring blades II 92 far from the rotating pipe 91 are in close contact with the inner wall of the cylinder 1;

[0033] Furthermore, the stirring blades II 92 and the filter screen frame 54 are at the same horizontal height to scrape off the clay staying on the filter screen frame 54. If the clay adheres to the filter screen frame 54 in a large area, it will not only affect the flow of the oil liquid into the observation pipe 51, but also reduce the clay content in the remaining area inside the cylinder 1 and reduce the decolorization effect of the waste lubricating oil. Therefore, the rotating stirring blades II 92 are used to scrape off the clay adhering to the filter screen frame 54 while stirring the oil liquid and the clay;

[0034] Furthermore, the width of the stirring blades II 92 is greater than the inner diameter of the filter screen frame 54 to avoid omission;

[0035] Specifically, as Figure 5 shown, the steering mechanism 4 includes a mounting plate 41 fixedly connected to the middle of the lower end of the cylinder 1. An empty groove 42 is opened inside the mounting plate 41. A rotating rod 43 is arranged on the right part of the inner side of the empty groove 42. A first gear 44 is arranged on the lower part of the outer surface of the rotating rod 43;

[0036] The lower end of the transmission shaft 7 penetrates through the side wall of the cylinder body 1 and the empty groove 42 and is rotatably connected to the bottom wall of the empty groove 42. A second gear 10 is provided on the outer surface of the part of the transmission shaft 7 located in the empty groove 42, and the second gear 10 meshes with the first gear 44. The lower end of the rotating tube 91 penetrates through the side wall of the cylinder body 1 and the empty groove 42 and extends into the empty groove 42. A belt transmission mechanism 45 is jointly provided between the outer surface of the part of the rotating tube 91 located in the empty groove 42 and the outer surface of the rotating rod 43. The belt transmission mechanism 45 consists of a transmission belt and two belt pulleys. This is a simple prior art, so no more detailed description will be given;

[0037] As can be seen from the above, when the transmission shaft 7 controls the rotation of the first stirring assembly 8, it will also control the rotating rod 43 to rotate in the opposite direction through the meshing second gear 10 and first gear 44, and then the rotating rod 43 will control the rotating tube 91 to rotate in the same direction through the first gear 44, so that the second stirring assembly 9 rotates in the opposite direction to the first stirring assembly 8, improving the mixing effect of the waste lubricating oil and the clay.

[0038] Therefore, the specific implementation manner of the present utility model is as follows:

[0039] The motor 2 first controls the rotation of the first stirring assembly 8 through the transmission shaft 7. Among them, the F-shaped stirring rod 82 continuously moves back and forth in the positioning tube 81 by using the wavy annular groove 6 to change the stirring range of the first stirring blade 83. When the transmission shaft 7 rotates, it will also control the rotating rod 43 to rotate in the opposite direction through the meshing second gear 10 and first gear 44, and then the rotating rod 43 will control the rotating tube 91 to rotate in the same direction through the first gear 44, so that the second stirring blade 92 rotates in the opposite direction to the first stirring blade 83, enabling the clay and the waste lubricating oil to be more fully mixed in the vertical direction, avoiding the layering phenomenon that may be caused by single-direction stirring, improving the mixing effect of the waste lubricating oil and the clay. In addition, the shear force generated when the first stirring assembly 8 and the second stirring assembly 9 rotate in the opposite direction can also effectively break the agglomeration between the clay particles and between the clay and the oil liquid, making the clay more dispersed and further improving the clay adsorption efficiency;

[0040] After that, rotate the turntable to control the rotation and outward movement of the screw rod 53 and the piston plate 52, so that the oil liquid in the cylinder body 1 can freely flow into the observation tube 51, facilitating the staff to first check the decolorization situation of the oil liquid, and finally discharging the oil liquid through the discharge pipe 3.

[0041] It should be noted that the specific installation method, circuit connection method, and control method of the motor 2 in the present utility model are all conventional designs, and the present utility model will not be elaborated in detail.

[0042] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements fall within the scope of the present utility model claimed. The scope of protection of the present utility model is defined by the appended claims and their equivalents.
