Drying device for producing foamed ceramic powder

Abstract

A drying device for producing foamed ceramic powder comprises a conical shell, a shell top end hot air port, a discharge outlet formed in the bottom of the shell, a feed inlet in the side wall of the upper end of the shell, an air outlet in the side wall of the lower end of the shell, and a spray pipeline connected with the feed inlet. The feed inlet is connected with a feed pipeline which is provided with a tubular heat exchanger. The tubular heat exchanger is connected with the air outlet. Energy consumption is greatly reduced, and drying efficiency is improved.

Description

technical field [0001] The invention relates to the field of refractory and thermal insulation materials, in particular to a drying device for refractory raw materials. Background technique [0002] The drying tower disperses the material to be dried into very fine mist-like particles through mechanical action, (increasing the water evaporation area and accelerating the drying process) in contact with hot air, and removes most of the water in an instant, making the material in the The solid matter dries to a powder. Its drying needs a large amount of heat sources to dry, and the energy consumption is large. Those skilled in the art have found that preheating the materials will speed up the drying efficiency, and the required heat is small, which can greatly reduce energy consumption. The drying tower of the prior art Generally, the material is heated, but it requires an additional heat source, which invisibly increases a certain amount of energy consumption and needs to be ...

AI Technical Summary

Problems solved by technology

Its drying requires a large amount of heat sources for drying, which consumes a lot of energy. Those skilled in the art have found that preheating the materials will speed up the drying efficiency, and the required heat is small, which can greatly reduce energy consumption. The drying tower of the prior art Generally, the material is heated, but it needs another heat source, which also increases a certain amount of energy consumption, which needs to be improved.
