[0002] The pin-type sand mill is a machine suitable for ultrafine dispersion and nano-level grinding of water-based and solvent-based materials. It is mainly used for grinding materials such as inkjet, paint, dyes and pigments. Due to the current demand for paints, dyes and other materials, the pin-type sand mill is increasingly valued by people. For some paints, dyes and other materials, it not only has a good grinding effect, but also the ground paints and other materials are more fine.

[0003] In the prior art, the paint slurry after grinding by a pin-type sand mill is passed through a screen to separate the paint slurry and the grinding medium. During the separation process, a thin film of viscous slurry will condense on the surface of the screen, causing the screen holes to be blocked, affecting the separation speed of the paint slurry.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: Figure 1-Figure 4 As shown, the utility model provides a nanorod pin-type sand mill with an anti-blocking screen, comprising: a base 1 and a transmission belt 16, a mounting plate 2 is fixedly connected to the top of the base 1, a grinding barrel 13 is arranged on the rear surface of the mounting plate 2, a rotating rod 6 is rotatably connected to the inner surface of the mounting plate 2, and a grinding assembly 7 is arranged on the rear end face of the rotating rod 6; a grinding assembly 7, the grinding assembly 7 comprises a mounting column 701 and a sieve plate 704, the front end face of the mounting column 701 is fixedly connected to the rear end face of the rotating rod 6, a plurality of fixed rods 705 are equidistantly fixedly connected to the outer surface of the mounting column 701, a mounting disk 702 is fixedly connected to the rear end face of the mounting disk 702, a plurality of scrapers 703 are equidistantly fixedly connected to the inner surface of the grinding barrel 13, and the sieve plate 70 4 is fitted with the outer surfaces of multiple scrapers 703, the top of the base 1 is fixedly connected to the motor 9, the output end of the motor 9 is fixedly connected to the second pulley 8, the outer surface of the rotating rod 6 is fixedly connected to the first pulley 5, the first pulley 5 and the second pulley 8 are connected by a transmission belt 16, the top of the base 1 is symmetrically fixedly connected to the U-shaped frame 10, the inner surfaces of the two U-shaped frames 10 are fixedly connected to the sliding rod 11, the outer surface of the grinding barrel 13 is symmetrically fixedly connected to the connecting block 12, the inner surfaces of the two connecting blocks 12 are respectively slidably connected to the outer surfaces of the two sliding rods 11, the inner side of the base 1 is fixedly connected to the electric telescopic rod 15, the telescopic end of the electric telescopic rod 15 is fixedly connected to the mounting block 14, and the mounting block 14 is fixedly connected to the outer surface of the grinding barrel 13.

[0023] The effect achieved by the entire embodiment 1 is that when the nanorod pin-type sand mill with an anti-blocking screen is used, the electric telescopic rod 15 fixedly arranged on the inner side of the base 1 is started, and its telescopic end contracts, pulling the mounting block 14 to move the grinding barrel 13 forward. The two connecting blocks 12 symmetrically fixedly connected to the outer surface of the grinding barrel 13 synchronously slide along the surface of the sliding rod 11 fixedly connected to the inner surface of the two U-shaped frames 10 until the grinding barrel 13 hits the surface of the sealing gasket 4, which plays a sealing role.

[0026] Working principle: When the nanorod pin type sand mill with anti-blocking screen is in use, the electric telescopic rod 15 fixed on the inner side of the base 1 is started, and its telescopic end contracts, pulling the mounting block 14 to move the grinding barrel 13 forward. The two connecting blocks 12 symmetrically fixedly connected on the outer surface of the grinding barrel 13 slide synchronously along the surface of the sliding rod 11 fixedly connected on the inner surface of the two U-shaped frames 10 until the grinding barrel 13 hits the surface of the sealing gasket 4. The sealing gasket 4 deforms under the action of pressure, so that the deformed part fills the gap between the two, preventing liquid material from leaking from the gap, thereby improving the sealing performance of the nanorod pin type sand mill with anti-blocking screen. The water-based paint is injected from the feed port set on the top of the grinding barrel 13, and the grinding balls for grinding are placed in the sealed grinding barrel 13 together, and the motor 9 is started. The output end of the motor 9 drives the second The pulley 8 rotates rapidly and transmits the power to the first pulley 5 through the transmission belt 16. The rotating rod 6 drives the mounting column 701 to rotate at high speed inside the grinding barrel 13. The multiple fixed rods 705 fixed on its surface rotate the grinding material and the grinding balls at the same time, so that the grinding balls constantly collide with each other in a disordered manner in the grinding barrel 13, and the material is ultra-finely ground until it reaches the nanometer standard. When the material flows to one side of the grinding barrel 13 through the multiple tiny holes on the surface of the sieve plate 704, the mounting disk 702 fixed on the mounting column 701 synchronously drives multiple scrapers 703 to rub on the outer surface of the sieve plate 704, thereby scraping off the thin film on the surface of the sieve plate 704 from its surface, preventing the viscous liquid material from condensing into a thin film on the surface of the screen, causing the screen holes to be blocked and affecting the separation speed of the paint slurry, thereby greatly improving the separation speed of the screen plate for the material.
