Three-dimensional dynamic turn-back flow preheating, drying and calcining system

Abstract

The invention discloses a three-dimensional dynamic turn-back flow preheating, drying and calcining system. A first preheater is arranged on the side edge of a first elevator, a second preheater is arranged on the side edge of a second elevator, a first calcinator is arranged on the side edge of a third elevator, a second calcinator is arranged on the side edge of a fourth elevator, a first cooleris arranged on the side edge of a fifth elevator, a second cooler is arranged on the side edge of a sixth elevator, a feeding port of the first elevator is connected to a stock bin through an auger,a first high-temperature heating source is arranged on a middle machine body of the first calcinator, a second tail gas hot air outlet is formed in the rear end of the first calcinator, a second high-temperature heating source is arranged on a middle machine body of the second calcinator, and a third tail gas hot air outlet is formed in the rear end of the second calcinator. A three-dimensional inclined plate turn-back flowing process is adopted, so that the preheating, drying and calcining time of the materials can be ensured. Meanwhile, no power exists in the turn-back flow process, the natural flow process can guarantee uniform material calcination, the production cost is saved, and automatic production can be achieved.

Description

technical field [0001] The application relates to a three-dimensional dynamic reentry flow preheating drying and calcining system, specifically in the field of drying and calcining. Background technique [0002] At present, in the field of powder material combustion, the basic heating device is internal heating or external heating, so it is easy to pollute the product during the heating process, the material loss is large, the energy consumption is large, and the cost is high. Therefore, it is necessary to study a material loss and low cost. calcination system. Contents of the invention [0003] The purpose of the present invention is to provide a three-dimensional dynamic reentry flow preheating drying and calcining system to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a three-dimensional dynamic reentry flow preheating drying and c...
