Full-automatic double-layer electric heating roller way kiln

Abstract

The invention discloses a full-automatic double-layer electric heating roller way kiln. The full-automatic double-layer electric heating roller way kiln comprises a kiln body and an automatic feeding and discharging circulation system. The kiln body comprises a lower kiln body layer and an upper kiln body layer. A feeding inlet is formed in the front end of the upper kiln body layer. A discharging outlet is formed in the front end of the lower kiln body layer. The rear end of the upper kiln body layer is flush with the rear end of the lower kiln body layer. The automatic feeding and discharging circulation system comprises a feeding mechanism arranged corresponding to the feeding inlet, a discharging mechanism arranged corresponding to the discharging outlet, and a transferring mechanism used for transferring materials in the upper kiln body layer into the lower kiln body layer. The upper kiln body layer and the lower kiln body layer are internally provided with roller ways correspondingly. A waste heat preheating section, a pre-drying section, a drying section, a temperature increasing section, a sintering zone and a temperature decreasing zone are sequentially arranged in the kiln body in the advancing direction of the materials. The pre-drying section comprises a waste heat pre-drying section close to the waste heat preheating section, and a heating pre-drying section away from the waste heat preheating section. An exhaust fan is arranged in the temperature decreasing zone. An air outlet of the exhaust fan communicates with the waste heat preheating section and the waste heat pre-drying section.

Description

technical field [0001] The invention belongs to the technical field of kilns, in particular to a fully automatic double-layer electric heating roller kiln. Background technique [0002] The traditional electric kiln mostly uses single-channel one-way operation. The product passes through the preheating zone, heating zone, high temperature zone, heat preservation zone and cooling zone in the electric kiln body, and there are heating pipes on both sides of the firing channel to the kiln. It is widely used in the sintering of structural ceramics, functional ceramics, phosphors, rare earth materials, lithium battery materials (lithium cobalt oxide), magnetic materials, nanomaterials, etc., but the heat utilization rate of this electric kiln during the heating process Low energy consumption and high energy consumption, improving the energy utilization efficiency of kilns has become the focus of energy conservation and emission reduction in various industries. [0003] The Chines...

AI Technical Summary

Problems solved by technology

Although the double-layer sintering kiln can achieve the technical purpose of saving energy to a certain extent, the upper and lower layers of the kiln operate independently, which is equivalent to the superposition of two single-channel and one-way operation kilns, which cannot reduce The technical effect of the footprint
