Specific embodiments

[0020] Now, the present utility model will be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] Please refer to Figures 1-4 , a raw material grinding device for lubricating oil production, including a base 1 and a support seat 2 above the base 1. A grinding cylinder 3 is provided between the two support seats 2. Main bearings 21 are provided on both of the two support seats 2. The grinding cylinder 3 rotates between the two support seats 2 through the main bearings 21. One end of the grinding cylinder 3 is provided with a feed inlet 31, and the feed inlet 31 extends outwards through the support seat 2. A discharge groove 32 is provided on the circumference of the grinding cylinder 3. Normally, the feed inlet 31 and the discharge groove 32 are sealed. A plurality of grinding balls 7 are provided inside the grinding cylinder 3, and the grinding cylinder 3 operates through a driving mechanism.

[0022] During use, the material to be ground is injected into the grinding cylinder 3 through the feed inlet 31, and then the driving mechanism is started. After the driving mechanism operates, the grinding cylinder 3 starts to rotate. Since the grinding balls 7 are provided inside the grinding cylinder 3, when the grinding cylinder 3 rotates, the grinding balls 7 continuously roll and will crush and grind the material. After the grinding is completed, the material is discharged through the discharge groove 32.

[0023] In this embodiment, the driving mechanism includes a motor 5, a speed reducer 51, a driving gear 52, a driving shaft 53, and a gear disc 4. The gear disc 4 is arranged on the circumference of the grinding cylinder 3. The motor 5 and the speed reducer 51 are fixed on the surface of the base 1. One end of the driving shaft 53 is in transmission connection with the speed reducer 51, and the other end is rotatably connected to the support base 2. The driving gear 52 is fixed on the driving shaft 53, and the driving gear 52 meshes with the gear disc 4 outside the grinding cylinder 3. Among them, the motor 5, the speed reducer 51, the driving gear 52, and the driving shaft 53 are coaxially arranged. After the motor 5 operates, the grinding cylinder 3 is driven to rotate through the driving shaft 53 and the driving gear 52. The continuous rotation of the grinding cylinder 3 can continuously grind the material, improving the grinding efficiency and quality.

[0024] To increase the grinding efficiency, a lining cylinder 6 is provided on the inner wall of the grinding cylinder 3. The cross-section of the lining cylinder 6 is a regular octagon. A plurality of grinding balls 7 are arranged in the regular octagon-shaped lining cylinder 6. In addition, the outer diameters of a plurality of the grinding balls 7 are inconsistent. After the grinding cylinder 3 rotates, the grinding balls 7 hit the internal material.

[0025] That is to say, when the grinding cylinder 3 operates through the driving mechanism, a certain centrifugal force will be generated on the internal material and the grinding balls 7. The internal grinding balls 7 will rise to a certain height by the centrifugal force. When the grinding balls 7 rise to a certain height, they will fall. For details, please refer to Figure 5 , when the grinding balls fall, they will hit inside the lining cylinder 6. Repeating this movement will grind and crush the material.

[0026] Since the inner wall of the lining cylinder 6 is a regular octagon with edges and corners, the edges and corners of the regular octagon can increase the centrifugal height of the grinding balls 7 during rotation, increase the impact force when the grinding balls 7 fall, improve the grinding efficiency, and meet the grinding requirements of the material.

[0027] As a preferred solution, a receiving box 8 is further provided on the surface of the base 1. The receiving box 8 is detachably connected to the base 1. The receiving box 8 is arranged directly below the grinding cylinder 3. The length of the receiving box 8 is greater than the length of the discharge chute 32, ensuring that the material completely falls into the discharge chute 32 after the grinding process is completed.

[0028] In addition, a slideway 11 is provided on the surface of the base 1. The bottom surface of the receiving box 8 is provided with a slider that matches the slideway 11. The receiving box 8 is detachably connected to the base through the cooperation of the slider and the slideway 11. After the grinding process is completed, the receiving box 8 is installed on the base 1 through the cooperation of the slider and the slideway 11, and then the discharge chute 32 is opened to allow the material to fall into the discharge chute 32. After the discharge is completed, the receiving box 8 can be removed.

[0029] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of this utility model creation.
