Technological method for circularly firing coal gangue green bricks

Abstract

A technological method for circularly firing coal gangue green bricks comprises the steps that a circular circulating kiln channel is arranged outdoors, movable stacking equipment, kiln equipment and brick stack packaging equipment are arranged and installed along the circular circulating kiln channel, and the circular circulating kiln channel is matched with the stacking equipment, the kiln equipment and the brick stack packaging equipment to complete circular continuous firing operation of the coal gangue green bricks. The technological method has the beneficial effects that the kiln channel is arranged in the open air, green brick laying operation and finished brick unstacking operation in the technological process belong to outdoor operation, the working environment is good, the operable space is large, the whole technological process is completed through the operation that movable kiln equipment is configured with automatic mechanical equipment, the mechanization degree is high, the labor input is reduced, and the working efficiency is improved; and the drying, preheating and roasting processes of brick stacks are controlled by moving the kiln, the operation is simple and convenient, and the process control is accurate; and the green brick firing operation is circulated, large-scale continuous production of coal gangue brick making is achieved, the speed is high, the efficiency is high, and the productivity is improved.

Description

technical field [0001] The invention belongs to the technical field of coal gangue brick making, and in particular relates to a process method for cyclically firing coal gangue brick adobes. Background technique [0002] Using coal gangue instead of clay as a raw material for brick making bricks not only prevents the mining and damage of clay in the brick making industry, but also uses the combustible materials contained in the raw materials to sinter the bricks spontaneously, saving fuel consumption. In addition, coal gangue is a solid waste. There are a large amount of coal gangue in major coal mines in my country, which has caused serious harm to the environment. Using coal gangue to make bricks can not only be used as waste, but also has great significance for environmental protection. It is a key project encouraged by the state and has become the development trend of the industry. [0003] The adobe firing process adopted in the existing brick-making field is based on a...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing coal gangue brick adobe firing process has a closed site and outdated operation methods, and brick adobe stacking and brick-forming transportation must be completed in the kiln, resulting in low mechanization, difficult transformation, high labor costs, and low production efficiency. In order to solve the problem of low efficiency, a process method for cyclically firing coal gangue adobes is provided that can stack adobes outside the kiln and transport them into bricks.
