Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pyrophyllite block production, in particular to a calcining device for pyrophyllite block production. BACKGROUND

[0002] Pyrophyllite contains little structural water (only 5.0%), and the volume shrinkage caused by dehydration during heating is small, the dehydration process is relatively slow, and the dehydration process is relatively long, from 590 DEG C to about 1100 DEG C. After heating and dehydration, the original crystal structure is still maintained. Based on the above properties, the raw material can be directly used to make unburned bricks. The hardness and compressive strength of pyrophyllite increase with the increase of heating temperature, and the reason is that the phase changes;

[0003] When pyrophyllite raw materials are used, the T characteristics should be determined according to the characteristics of the raw materials. Pyrophyllite has small thermal expansion, little structural water, only 5% to 6% weight loss during dehydration, and slow dehydration process. After dehydration, the original crystal structure is still maintained, so raw materials can be directly used to make bricks. In order to reduce production cost, mineral powder can also be used. However, when raw materials are used to make bricks, the volume expansion caused by pyrophyllite dehydration and quartz polymorphic transformation will make the product loose and reduce the strength. Therefore, part of the raw materials can be calcined into clinker and added to the batching. Due to the small expansion characteristics of pyrophyllite, the product can be unburned, or according to the use requirements, the burned product can be produced;

[0004] Generally, the kiln is used in silicate industry, and the furnace is used for metal heating. The gas industrial furnace is generally composed of furnace, hearth, waste heat utilization device, smoke exhaust device, furnace door and lifting device, metal frame, mechanical transmission device and the like, and is attached with various control systems and the like. According to the different needs of production process, the gas industrial furnace has various structure types: according to the use, there are heating furnace and melting furnace; according to the furnace temperature, there are high temperature furnace, medium temperature furnace and low temperature furnace.

[0005] 1. In the actual calcination process of pyrophyllite, the stone in the crucible in the calcination furnace is heated to a high temperature of nearly one thousand degrees. After the calcination of pyrophyllite is completed, the crucible needs to be taken out from the calcination furnace and replaced with new materials for the next calcination. However, if the crucible is clamped by the staff with tools during this process, the safety hidden danger is too large, and the staff is prone to operation error due to long-term mechanical repetition of this action process. If the operation error occurs, the staff is easy to be scalded, which further causes production accidents;
