Title:
METHOD FOR PRODUCING POLYPHOSPHATE
Document Type and Number:
WIPO Patent Application WO/2022/142860
Kind Code:
A1
Abstract:
Disclosed is a method for producing polyphosphate. The method comprises a production system using the following structures, including a premixer, a polymerization reactor, a material distribution device, a cutting device, a crusher, a conveyor and a packaging machine, and comprises the following preparation process: step 1, uniformly mixing a raw material and an additive in proportion in the premixer; step 2, uniformly spraying a liquid material obtained after uniform mixing in the premixer onto a belt conveying assembly of the polymerization reactor by means of the material distribution device, and by means of the belt conveying assembly, conveying the liquid material into a high-temperature area in the polymerization reactor to react for 0.5-2 h, and then into a low-temperature area in the polymerization reactor for cooling, so as to complete a polymer curing process; and step 3, scraping off cured and cooled polyphosphate by means of the cutting device, and entering the scraped polyphosphate into the crusher for crushing. The method is mainly used for rapidly and continuously preparing a polyphosphate, and has the advantages of a high degree of automation and high production efficiency.
