Water polluted bottom mud high-performance modifier granulation apparatus and granulation method

Abstract

The invention discloses a water polluted bottom mud high-performance modifier granulating apparatus and granulation method. The granulation apparatus comprises a supercharging extrusion mechanism, a rotary cutting mechanism, a cooling mechanism and a driving mechanism, wherein the supercharging extrusion mechanism comprises a hollow cabin and a supercharging pump which are coaxially and successively connected, a threaded rod and a threaded sleeve are coaxially arranged inside the hollow cabin, the rotary cutting mechanism comprises a rotary cutter and a granule control mold, the granule control mold is connected with a material outlet of a supercharging pump, the rotary cutter is arranged at the material outlet of the granule control mold, the cooling mechanism comprises a cooling casing pipe, the cooling casing pipe is filled with cooling fluid, and the cooling casing pipe is spirally arranged outside the hollow cabin and the supercharging pump. The cooling casing pipe is spirally arranged outside the supercharging extrusion mechanism, so that heat produced in the working process can be rapidly dissipated, the problem that the original characteristics of the material are changed due to the excessive heat can be avoided, the activity of a chemical composition in modifier granules is ensured, so that the production quality of the modifier granules is improved.

Description

technical field [0001] The invention relates to the technical field of preparing granular modifiers, in particular to a granulation device and a granulation method for high-efficiency modifiers of water body polluted sediment. Background technique [0002] At present, the granulation device has become an important equipment for preparing mixed bulk materials into shaped products. Then, the existing granulation device is equipped with an extrusion molding device, which will generate a lot of heat during the extrusion molding process. For some For the raw materials of chemical synthetics, using the existing granulation equipment for production will cause the chemical synthetics to be heated to change the original characteristics, which will lead to the problem of unqualified granulation; [0003] Therefore, there is an urgent need to provide a raw material granulation device suitable for chemical compounds. Contents of the invention [0004] Aiming at the problem that the e...
