Abstract

The invention relates to a secondary drying equipment for powder, which is used to bake and dry the bamboo and wood powder; the invention improves the drying mode of primary drying and primary wet discharge of the existing drying equipment into the drying mode of secondary drying and secondary wet discharge, fully use the waste heat between a baking chamber and a coil pipe, and improves the drying effect of materials; simultaneously, the heat is sucked out of the baking chamber when secondary drying, which reduces the furnace temperature, protects a furnace body, and increases the service life of the furnace body.

Description

technical field [0001] The invention relates to a drying equipment which uses gas to carry powder together for drying, in particular to a secondary drying equipment used for baking and drying bamboo and wood powder. Background technique [0002] There is a key process before the production of bamboo and wood powder carbon rods is to dry the bamboo and wood powder. Chinese patent CN1734220 discloses a powder drying equipment. In order to solve the direct contact between the bamboo and wood powder and the flame in the existing drying method, it is easy to cause Burning bamboo wood powder causes waste and disaster problems. This patent includes a baking barrel, an external connecting pipe, a blower, and a storage barrel. The combustion chamber and the baking cavity are composed of an outer barrel body, an inner barrel body, a barrel bottom plate, a furnace mouth, and a flue. The baking barrel is vertically erected, and the There is an inner tube spirally spiraling at least onc...
