A translational titanium gypsum calcination equipment

Abstract

The invention discloses a translational titanium gypsum calcining equipment, which belongs to the technical field of titanium gypsum calcining. The invention includes a feeding mechanism, a high-temperature calcination mechanism, a translational drying mechanism, a hot air circulation supply mechanism, and a material discharge mechanism; wherein, the high-temperature calcination mechanism is vertically arranged, and the material feeding mechanism sends materials into the upper end of the high-temperature calcination mechanism. The material falls into the translational drying mechanism after passing through the high-temperature calcination mechanism. A translational conveyor belt moving along the horizontal direction is arranged inside the translational drying mechanism. The translational conveyor belt transports the material to the discharge mechanism, and the discharge mechanism sends the dried material out for storage; The hot air circulation supply mechanism provides circulating hot air for the high temperature calcination mechanism and the translational drying mechanism. The drying material of the present invention has no agglomeration, uniform humidity inside and outside, high product quality, and the present invention adopts a special biomass fuel burner to provide heat source, low energy consumption, energy saving, environmental protection, and is convenient for popularization and application in enterprises.

Description

technical field [0001] The invention relates to the technical field of titanium gypsum calcination, and more specifically, relates to a translational titanium gypsum calcination equipment. Background technique [0002] Titanium gypsum is an industrial waste residue mainly composed of dihydrate gypsum produced by adding lime to neutralize a large amount of acid wastewater in order to treat acid wastewater when sulfuric acid method is used to produce titanium dioxide. Titanium gypsum has the characteristics of high water content, high viscosity and high impurity content. In recent years, with the rapid development of the titanium industry, the production and storage of titanium gypsum in my country have been increasing. However, the status quo of dehydration processing and large-scale centralized utilization of titanium gypsum has not been ideal, so that titanium gypsum Pile up into mountains, waste arable land, rain washes away, drains the surface, and pollutes groundwater ab...

AI Technical Summary

Problems solved by technology

The main disadvantages are as follows: (1) The process is long, the equipment is many and huge, and the maintenance cost is high; (2) The material is easy to agglomerate, the humidity inside and outside the drying material is uneven, and the product quality is low; (3) The energy consumption is high , the energy utilization efficiency is low, which is not conducive to energy saving and environmental protection; (4) The coal used for calcination pollutes the air, and the unrecovered titanium gypsum powder floats into the air, causing air pollution

However, the structure of the application is complex and the cost of equipment maintenance is high, so further improvement is still needed
