[0031] The primary crushing assembly 3 includes a load-bearing block 3-1, which is arranged between the outer shell 1 and the inner partition layer 2. A downward discharge opening 3-2 is formed on the surface of the inner partition layer 2, and a docking groove 3-3 is formed on the side surface of the load-bearing block 3-1.

The thickness and position of the dispersion tool holders 3-7 correspond to those of the docking groove 3-3. One end of the movable rod 3-4 is connected with a transverse shaft 3-9. An outer plate 3-10 is fixedly connected to the side surface of the outer shell 1, and a driving motor 3-11 is installed on the surface of the outer plate 3-10.

A baffle 3-14 is fixedly connected to the top inside the outer shell 1, and the baffle 3-14 is located above the impact block 3-6.

[0032] In this embodiment, in order to achieve the effect of initially crushing polyacrylamide with a relatively large volume, the primary crushing assembly 3 is designed. A load-bearing block 3-1 is arranged inside the outer shell 1 and a docking groove 3-3 is formed. A downward discharge opening 3-2 is formed on the surface of the inner partition layer 2 for passing through the material to be crushed. Slideway grooves 3-5 are formed on both sides inside the outer shell 1 and impact blocks 3-6 are slidably connected therein. Movable rods 3-4 are arranged on both sides of the side surface of the impact block 3-6. The movable rods 3-4 pass through the load-bearing block 3-1 and the surface of the outer shell 1 and are located outside. A transverse shaft 3-9 is arranged at one end of the movable rod 3-4. An outer plate 3-10 is fixed on the outer surface of the outer shell 1 and a driving motor 3-11 is installed thereon. A driving frame 3-12 is arranged at the output end of the driving motor 3-11. A connecting shaft rod 3-13 is connected between the driving frame 3-12 and the transverse shaft 3-9. When the driving frame 3-12 rotates, the movable rod 3-4 can be repeatedly pushed and pulled through the connecting shaft rod 3-13, so that the impact block 3-6 repeatedly hits the load-bearing block 3-1. Dispersion tool holders 3-7 and impact layers 3-8 are arranged on the surface of the impact block 3-6 for crushing the material.

[0033] Furthermore, the refined crushing assembly 4 includes a pair of coarse crushing rollers 4-1, which are both rotatably connected inside the outer shell 1 and are controlled to rotate by a motor. Transmission gears 4-2 are arranged at one end of the rotating shafts of the pair of coarse crushing rollers 4-1, and the transmission gears 4-2 are meshed with each other.

A discharge opening 4-5 is formed at the lower end of the side surface of the outer shell 1.

[0034] In this embodiment, in order to achieve a further crushing effect, a refined crushing component 4 is designed. Inside the housing 1, two coarse crushing rollers 4-1 and two fine crushing rollers 4-4 are rotatably connected. The coarse crushing rollers 4-1 are synchronously rotated through the transmission of the driving gear 4-2 by a motor. A centralized cover 4-3 is also provided, which can concentrate the materials at the fine crushing rollers 4-4 for final refinement. At the bottom on one side of the housing 1, a discharge port 4-5 is provided for discharging the materials outward.

[0037] Further, a centralized hopper 5 is provided at the lower end of the outer surface of the housing 1, and the centralized hopper 5 is located below the discharge port 4-5.

[0038] In this embodiment, by installing the centralized hopper 5, the discharged materials are concentrated in one position, facilitating collection.

[0039] Further, a baffle 6 is provided on the bottom surface of the inner partition layer 2, and the baffle 6 is located on one side at the top of the fine crushing roller 4-4.

[0040] In this embodiment, by installing the baffle 6, it is possible to prevent the materials from bouncing outwards when the coarse crushing roller 4-1 is crushing.

[0041] Further, the lower discharge openings 3-2 are evenly formed in a grid shape on the inner partition layer 2.

[0042] In this embodiment, through the grid-shaped opening structure, the preliminarily crushed materials can be discharged downward through the openings of the grid.

[0043] When crushing treatment is required, start the driving motor 3-11 to make the impact block 3-6 start to move repeatedly. After the materials are put in at the top, they are preliminarily crushed by the dispersion tool holder 3-7 and the impact layer 3-8. The crushed materials fall downward through the grid-shaped lower discharge openings. Start the coarse crushing roller 4-1 and the fine crushing roller 4-4. First, they are crushed by the coarse crushing roller 4-1 and then slide downward through the inclined angle of the centralized cover 4-3. After being further crushed by the fine crushing roller 4-4, they are discharged at the discharge port 4-5.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
