Embodiment Construction

[0037]The present invention is described in conjunction with accompanying drawing and given embodiment, but does not form any restriction to the present invention:

[0038] Such as figure 1 , figure 2 shown, and refer to image 3 , a multi-layer calciner for granular materials, mainly including a furnace body, a feed part, a discharge part, a heating part and a control system; the furnace body is vertical, and the furnace body is composed of a furnace shell 8, a furnace lining 12 Composition; the feed part located at the upper part of the furnace body mainly includes a feed bin 1, a feeder 2 and a feed port 3; the feeder 2 can adopt a rotary feeder, a screw feeder, a push Rod conveyor etc., feeder 2 adopts rotary feeder in this embodiment. There is a calcination cabin in the hearth of the furnace body. In this embodiment, the calcination cabin bulkhead 9 is a square cylinder structure, which can avoid the contact between the material and the furnace lining, so that the pro...

Abstract

The invention provides a granular material multilayer calcining furnace which is in a vertical shape. The calcining furnace is characterized in that a cavity is composed of a furnace lining (12) and provided with at least one calcining cabin, and the calcining cabin is provided with a feed inlet (3) and a discharge port (6); a heating component (10) has three arrangement manners, and the heating component (10) is arranged in a gap between the periphery of the calcining cabin and the furnace lining; the heating component (10) is arranged in the calcining cabin, and the heating component (10) is simultaneously arranged on the interior and exterior of the calcining cabin; and the calcining cabin is in a longitudinal layered architecture, and the longitudinal layered architecture is a row or multiple rows. The granular material multilayer calcining furnace provided by the invention has the advantages that a vertical type furnace carries out continuous incineration on the grain materials, the materials are fully dispersed in a calcination process through a multilayer calcining layer so as to uniformly heat and difficult in caking and easy to flow, thereby fully contacting with furnace atmosphere, the furnace atmosphere is controllable, and the yield product is high; and a vertical type structure is adopted, the energy is saved, the efficiency is high, the investment is less, the occupied space is small, and the use is convenient and reliable.

Description

technical field [0001] The invention relates to a calciner, and mainly provides a multi-layer calciner for granular materials and a calcining method. Background technique [0002] The calcination of materials is an essential work for people's production activities. By heating and calcining the materials, moisture, carbon dioxide, sulfur trioxide, organic matter and other substances in the materials can be removed to produce the materials people want, and new materials can be synthesized or sintered into new materials for production and life through calcination. The main process of calcination is a process of heating the material to the required temperature and controlling the atmosphere in the heating furnace at the same time. [0003] At present, there are mainly two types of kilns used for material calcination: continuous kilns and batch kilns: continuous kilns mainly include shaft kilns, multi-layer kilns, rotary kilns, tunnel kilns, pusher kilns, etc.; The late...
