Short-distance transport method for expanded perlite

Abstract

The application discloses a short-distance transportation method for expanded perlite. The short-distance transportation method of this expanded perlite, its specific steps are as follows: (1), blanking: introduce the perlite after the expanded perlite of preparation under uncooled situation into cyclone separator with induced draft fan; (2), packing: utilize cyclone The separator directly divides the uncooled expanded perlite into the thermal insulation storage tank and seals it; (3), transportation: transport the storage tank with high temperature expanded perlite as a whole; (4), production of thermal insulation device: directly put the storage tank The high-temperature expanded perlite in the tank is filled to the target position of the insulation device. The short-distance transportation method of expanded perlite described in the present invention can keep the heat of the expanded perlite, and the expanded perlite with high temperature can improve the filling efficiency.

Description

technical field [0001] The application relates to the application field of expanded perlite, in particular to a short-distance transportation method of expanded perlite. Background technique [0002] Expanded perlite is a kind of white granular material with a honeycomb structure inside, which is made of perlite ore after preheating and instantaneous high-temperature roasting and expansion. The principle is: the perlite ore is crushed to form ore with a certain particle size, preheated and roasted, heated rapidly, the water in the ore is vaporized, and expands inside the softened glassy ore to form a porous structure, which has good thermal insulation performance and expands The temperature of the final perlite is as high as 400-500°C, and it needs to be cooled before it can be packaged and transported. On the one hand, cooling takes time, resulting in low production efficiency and harsh production environment. On the other hand, the heat carried by expanded perlite cannot b...

On the one hand, cooling takes time, resulting in low production efficiency and harsh production environment. On the other hand, the heat carried by expanded perlite cannot be recycled. , resulting in a waste of resources
