Technical Field

[0001] This utility model relates to the field of grinding technology, and more specifically, to a polyacrylamide grinding machine. Background Technology

[0002] Polyacrylamide is a linear polymer with excellent flocculation, thickening, shear resistance, drag reduction, and dispersibility properties. Based on its ionic characteristics, it can be classified into nonionic, anionic, cationic, and amphoteric polyacrylamides. It has wide applications in industries such as water treatment, papermaking, oil extraction, textiles, and pharmaceuticals. For example, in water treatment, it can be used for flocculation and sedimentation to effectively purify water.

[0003] In the production and processing of polyacrylamide, a grinder is needed to grind it into powder. During grinding, the grinder uses a screening structure to remove substandard polyacrylamide particles, which are then re-added to the grinder. This screening and re-addition process is time-consuming and affects the efficiency of grinding polyacrylamide into powder. Therefore, we propose a polyacrylamide grinder. Utility Model Content

Detailed Implementation

[0021] like Figures 1 to 6 As shown, this utility model relates to a polyacrylamide grinding machine, including a grinding chamber 101, a feeding box 102 mounted on the grinding chamber 101, and a grinding mechanism 200 disposed within the grinding chamber 101. A discharge pipe 108 is provided at the lower end of the grinding chamber 101. The feeding box 102 communicates with the grinding chamber 101, and a feeding port 103 is provided at the upper end of the feeding box 102. The grinding mechanism 200 includes a grinding plate 207 disposed on the inner wall of the grinding chamber 101 and a grinding disc 203 rotatably mounted within the grinding chamber 101. Mounting rods 201 are arranged in an array within the grinding chamber 101, and mounting plates 202 are installed between the mounting rods 201. The grinding disc 203 is rotatably mounted on the upper end of the mounting plate 202, and a second motor 204 for driving the grinding disc 203 is disposed at the lower end of the mounting plate 202. This utility model, through the coordinated arrangement of the grinding and screening structures, can directly re-grind unqualified materials, ensuring the quality of material grinding, reducing the process of screening and re-adding, and improving the efficiency of polyacrylamide grinding.

[0022] Specifically, a hollow guide cylinder 104 is rotatably installed inside the feed box 102, and a first motor 105 is provided at the front end of the feed box 102. The output shaft of the first motor 105 is connected to the shaft of the hollow guide cylinder 104. The operation of the first motor 105 can rotate the hollow guide cylinder 104 to allow the material to enter the device for grinding.

[0023] Furthermore, a feeding plate 107 is provided on one inner wall of the feeding box 102, located on one side of the hollow guide cylinder 104. An electromagnet plate 106 is provided inside the feeding box 102 below the feeding plate 107, located on one side of the hollow guide cylinder 104. The feeding plate 107, in conjunction with the hollow guide cylinder 104, can limit the material movement. The first motor 105 drives the hollow guide cylinder 104 to rotate, which in turn drives the polyacrylamide granules into the material. The polyacrylamide granules entering the material impact the electromagnet plate 106 under the action of the hollow guide cylinder 104, and the electromagnet plate 106 can adsorb metallic substances in the material.

[0024] It is worth noting that the grinding plate 207 is arranged in a ring shape, and its cross-section is a U-shaped arc surface. There are two U-shaped arc surfaces, with the upper U-shaped arc surface bending outward at a wide angle. The wide angle of the upper part of the grinding plate 207, combined with the conical shape of the upper end of the grinding disc 203, allows materials to enter the grinding area. The U-shaped arc surface can fit against the arc surface of the side end of the grinding wheel 206, allowing the grinding wheel 206 to rotate within the U-shaped arc surface of the grinding plate 207.

[0025] It is worth noting that the upper end of the grinding disc 203 is tapered, and the side end of the grinding disc 203 is arrayed with mounting grooves 208. A grinding wheel 206 is rotatably mounted within the mounting grooves 208. The side end of the grinding wheel 206 is curved, and the grinding wheel 206 is located within the U-shaped curved surface of the grinding plate 207. The curved side end of the grinding wheel 206 can adapt to the curved shape of the grinding plate 207, allowing the grinding wheel 206 to rotate within the U-shaped curved surface of the grinding plate 207. The curved surface increases the contact area and grinding force, thereby crushing and grinding the polyacrylamide granules, improving grinding efficiency and quality.

[0026] It is worth noting that a sieve plate 205 is installed on the outer surface of the grinding disc 203. The sieve plate 205 is arranged in a ring shape and is located below the mounting groove 208. The distance between the sieve plate 205 and the grinding plate 207 is 1 mm. The ground polyacrylamide material can be screened through the sieve plate 205. Unqualified materials will be retained and thrown to the outside by the centrifugal force of the rotating grinding disc 203, allowing the material to re-enter the grinding area for grinding, thus ensuring the quality of material grinding.

[0027] Working Principle: This embodiment provides a polyacrylamide grinding mill. During use, polyacrylamide granules are fed into the feed box 102 through the inlet 103. The feeding plate 107, in conjunction with the hollow guide cylinder 104, can limit the material movement. The first motor 105 drives the hollow guide cylinder 104 to rotate, which in turn pulls the polyacrylamide granules into the mill. The entering polyacrylamide granules impact the electromagnet plate 106 under the action of the hollow guide cylinder 104. The electromagnet plate 106 can adsorb metallic substances in the material. Subsequently, the material enters the grinding chamber 101. The conical shape at the upper end of the grinding disc 203 allows for… The material is fed between the grinding wheel 206 and the grinding plate 207. The wide-angle setting at the upper end of the grinding plate 207 allows the material to enter the U-shaped arc surface. The second motor 204 rotates the grinding plate 207, and the grinding wheel 206 crushes and grinds the material inside the grinding plate 207. The ground polyacrylamide particles can fall onto the screening plate 205 for screening. The qualified powder material will fall off naturally, while the unqualified material will return to the grinding wheel 206 and the grinding plate 207 for grinding again under the action of centrifugal force. After being ground by the two sets of grinding wheels 206, the material can be discharged from the discharge pipe 108.

[0028] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
