Oil inlet lubricating, crushing and granulating device

Abstract

The invention relates to an oil inlet lubricating, crushing and granulating device. The oil inlet lubricating, crushing and granulating device comprises a pre-grinding machine and a granulating machine; the pre-grinding machine is connected with the granulating machine through a screw conveyor; a spraying nozzle is arranged in the granulating machine; the spraying nozzle is connected with a lubricating oil tank through a flow controller; the flow controller is connected with the weighing pre-grinding machine. According to the oil inlet lubricating, crushing and granulating device, the lubricating oil is atomized through the atomizing spraying nozzle and accordingly granules can be conveniently and rapidly cut through a polyacrylamide gel block, the molecular weight cannot be degraded and the polyacrylamide molecular weight cannot be reduced due to the rapid and effective cutting way, and meanwhile around 4 mm particle size of small colloidal particles can be obtained; the produced particles are uniform and loose, he liquidity is good, and the subsequent drying is easy; the lubricating oil is formed by the light oil and emulsified oil through mixture, the flow controller is connected with the weighing pre-grinding machine, the automatic adding is controlled by the screw conveyor, and accordingly the usage of the lubricating oil and the lubrication effect are effectively controlled, the environment-friendly effect is achieved, and the separation from finished products is facilitated.

Description

technical field [0001] The invention relates to a granulation device, in particular to an oil-feeding lubrication pulverization and granulation device. Background technique [0002] The production of polyacrylamide is based on the aqueous solution of acrylamide as the raw material, under the action of the initiator, the polymerization reaction is carried out, and the polyacrylamide rubber blocks formed after the reaction are cut, granulated, dried and crushed, and finally the polyacrylamide product is obtained . Polyacrylamide colloids are easy to form adhesions during the granulation process, which leads to excessive drying during the drying process, resulting in crosslinking, resulting in poor solubility of the final product and lower product quality. Contents of the invention [0003] Aiming at the problem that acrylamide colloids are easy to form adhesions in the granulation process in the prior art, the present invention provides a simple structure that can effec...
