Precast block blending mixing, vibration forming, curing and demolding process and system

Abstract

The invention relates to a precast block blending mixing, vibration forming, curing and demolding process and system. The system comprises a constant feeder, a three-hopper weighing vehicle, a bufferhopper, a discharge valve I, a liquid metering device, a vertical shaft stirrer, a feeding trolley, a limit switch, a discharge valve II, a vibrating table, a scraper, a hydraulic thruster, a conveying chain, a curing kiln, an automatic demolding machine, a manipulator, a drying vehicle and a drying kiln. By reasonably planning and designing the procedures and equipment of blending mixing, vibration forming, curing demolding and the like of a precast block, full-automatic control over the production technological process of a coke oven door precast block is achieved, an existing manual operation mode can be replaced, intelligent operation is achieved, and the production efficiency and the product quality are effectively improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated block production, in particular to a prefabricated block ingredient mixing, vibration molding, maintenance and demoulding process and system. Background technique [0002] Clay bricks, cordierite bricks, clay-cordierite bricks, bauxite-cordierite bricks or mullite-cordierite bricks are generally used as refractory materials for the lining of coke oven doors. The length and width of the bricks are generally 400-500mm, and the thickness of the bricks is generally between 120-200mm due to the limitation of machine pressing. [0003] The disadvantages of using machine-pressed bricks for the inner lining of coke oven doors are that the bricks are easy to be damaged due to many joints, low strength, short life, large amount of maintenance, poor sealing of the furnace door, poor heat preservation effect, and environmental pollution. Lining bricks greatly increase the work intensity of workers and ...

AI Technical Summary

Problems solved by technology

In the above-mentioned production process, manual weighing and feeding are mostly used in the batching mixing and vibration forming processes, and the batching errors are relatively large, and the dust spills out and pollutes the environment; the maintenance and demoulding process usually requires workers to use single-girder cranes to carry prefabricated blocks, and the production workload is heavy. low efficiency
