Description

Technical Field

[0001] This utility model relates to the field of polyacrylamide processing technology, specifically to a polyacrylamide cutting and conveying device. Background Technology

[0002] Polyacrylamide (PAM) is a linear polymer with the chemical formula (C3H5NO)n. It is a hard, glassy solid at room temperature, and products include liquids, latexes, white powders, translucent beads, and flakes. It exhibits good thermal stability. It is soluble in water in any proportion, forming a homogeneous and transparent liquid. Over long-term storage, the viscosity of the solution decreases due to the slow degradation of the polymer, especially under harsh storage and transportation conditions.

[0003] The existing polyacrylamide cutting and conveying device with patent number CN201210290789.X solves the problem of unstable gas pressure unloading from the reactor. However, this device does not optimize the cutting process of polyacrylamide. Generally, the lower part of the conical reactor has a material-forming rotating blade. The polymer is granulated at the same time as it is extruded. It is then dried and pulverized by a rotary drum dryer to obtain the product. However, polyacrylamide is prone to problems with uneven drying force affecting its cutting quality.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content
