Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] A polyacrylamide granulating device, in combination with Figure 1 , Figure 2 , comprising a cover 1, a particle mold 2, a pressing column 3, a scraper 4, a motor 5 and a water collecting platform 6, the particle mold 2 is fixedly connected in the cover 1, the pressing column 3 is slidingly connected in the particle mold 2, the scraper 4 is rotatably connected outside the particle mold 2 to shear the extruded material into particles, the motor 5 is erected at the bottom outside the cover 1, the motor 5 is connected with the scraper 4 to drive the scraper 4 to rotate around the particle mold 2, and the water collecting platform 6 is erected at the bottom outside the particle mold 2 to collect the water flowing out of the extruded material.

[0028] In combination with Figure 1 , Figure 2 , the cover 1 is in a cylindrical structure, the height of the cover 1 is greater than the height of the particle mold 2, the bottom of the cover 1 is provided with a cone 11, the cover 1 on one side of the cone 11 is provided with a discharge port 12, the cone 11 is arranged to collect the extruded material to the bottom of the cover 1, wherein the bottom of the cover 1 is located at the lowest height of the discharge port 12, so that the granular material can automatically roll down to the discharge port 12 to complete automatic discharge.

[0029] In combination with Figure 1 , Figure 3The particle mold 2 is a cylindrical shell and the bottom is hemispherical. A plurality of holes are arranged on the cylindrical surface and the hemispherical surface of the particle mold 2, and the holes on the hemispherical surface are much smaller than the holes on the cylindrical surface. The holes on the hemispherical surface only allow water to pass through, so as to avoid the material from being squeezed out of the particle mold 2. The particle mold 2 is fixedly connected with a feeding pipe 21, and the feeding pipe 21 is arc-shaped at one end close to the particle mold 2. The arc-shaped end of the feeding pipe 21 is in abutment with the outer end surface of the pressing column 3. The pressing column 3 is a metal cylinder, and the outer diameter of the pressing column 3 is equal to the inner diameter of the particle mold 2. The top of the pressing column 3 is provided with a connecting port 31 for connecting with a hydraulic machine. The bottom of the pressing column 3 is hemispherical, so as to guide the material to the two sides of the particle mold 2 when pressing, thereby improving the granulation effect. The hemispherical bottom of the pressing column 3 is provided with a flat bottom 32, and the outer diameter of the flat bottom 32 is smaller than the outer diameter of the pressing column 3. The flat bottom 32 is arranged to squeeze the water in the material, so that the water can be separated from the material.

[0030] When feeding, the pressing column 3 is lifted away from the particle mold 2, and at this time the feeding pipe 21 is communicated to pour the material into the particle mold 2. Then the hydraulic machine is started to make the pressing column 3 enter the particle mold 2. At this time, the material is squeezed out of the large holes of the particle mold 2 under the extrusion of the pressing column 3, and the water is flowed out of the particle mold 2 through the small holes on the hemispherical surface, so as to realize the functions of squeezing the material and squeezing the water. Then under the shearing action of the rotating scraper 4, the squeezed material is sheared into small pieces and falls on the frustum 11 and automatically flows out of the outer cover 1, thereby completing the granulation work.

[0031] In combination Figure 3 , Figure 4 The scraper 4 is a long strip-shaped straight plate. The output end of the motor 5 is rotatably connected with a rotating shaft 43. The bottoms of the three scrapers 4 are fixedly connected on the rotating shaft 43. The top of the scraper 4 is fixedly connected with a ring-shaped surrounding ring 42, so as to improve the connecting strength between the scrapers 4, thereby avoiding deformation after a long granulation time. The narrow edge of the scraper 4 is in abutment with the outer surface of the particle mold 2, so as to reduce the friction with the particle mold 2. The output torque of the motor 5 can be mostly used for shearing the material, thereby ensuring the smooth granulation work. The scraper 4 is fixedly connected with a conical rotating disc 41 at the position of the frustum 11. The rotating disc 41 connects the scrapers 4 and is in abutment with the particle mold 2 and the frustum 11, so as to avoid the material from flowing to the space of the motor 5 through the frustum 11 and causing waste.

[0032] In combination Figure 4 , Figure 5 The water collecting table 6 is a ring-shaped groove structure. The water collecting table 6 is installed in the frustum 11 below the rotating disc 41. The water collecting table 6 is opposite to the holes of the hemispherical position of the particle mold 2. The bottom of the water collecting table 6 is fixedly connected with a water pumping pipe 61 to pump the water falling into the water collecting table 6 out of the water collecting table 6. The water collecting table 6 is provided with a conical water guide table 62, which is in abutment with the rotating shaft 43 to avoid water flowing to the motor 5. The water collecting table 6 is arranged to collect the water left from the particle mold 2, so as to facilitate subsequent unified treatment to avoid pollution of the equipment and the motor 5.
