Brick pressing device used for flyash bricks

Abstract

The invention discloses a brick pressing device used for flyash bricks. The brick pressing device comprises a crushing and stirring device. The crushing and stirring device comprises a substrate. A base is arranged above the substrate, and a first supporting rod and a second supporting rod are fixed to the left end and the right end of the upper surface of the base. A driving wheel on a first motor output shaft is driven through a first motor to rotate, the driving wheel drives a first stirring shaft to rotate, first stirring blades are driven to rotate, and raw materials of flyash bricks arecrushed and stirred; the driving wheel drives a first driven wheel and a second driven wheel to rotate, a second stirring shaft and a third stirring shaft are driven to rotate, and finally second stirring blades and third stirring blades are driven to rotate; due to the fact that the first stirring blades, the second stirring blades and the third stirring blades are arranged in a staggered manner,raw materials of flyash bricks can be stirred and can be crushed; and the multiple stirring shafts and stirring blades are arranged at the same time, and therefore crushing and stirring can be more insufficient.

Description

technical field [0001] The invention relates to the technical field of fly ash bricks, in particular to a brick pressing device for fly ash bricks. Background technique [0002] The main raw materials of fly ash bricks are industrial waste solids such as fly ash, lime, gypsum, carbide slag, and carbide mud. It is a solid fly ash brick made of fly ash and lime as the main raw materials, mixed with appropriate amount of gypsum and aggregate, prepared from embryo material, pressed into shape, and cured by high-pressure or normal-pressure steam. Fly ash bricks can be used for walls and foundations of industrial and civil buildings. However, first-class bricks and first-class bricks must be used for foundations or for building parts that are susceptible to freeze-thaw and alternating wet and dry effects. At the same time, fly ash should not be used in parts subject to long-term heating, rapid cooling and rapid heating, and erosion by acidic media. [0003] Most of the existing...

AI Technical Summary

Problems solved by technology

At the same time, fly ash should not be used in parts subject to long-term heating, rapid cooling and rapid heating, and acid medium erosion.

[0003] Most of the existing brick pressing devices for fly ash bricks do not perform crushing and stirring operations before compaction, resulting in the subsequent brick pressing work is not easy to operate, and the pressed fly ash bricks have low compactness and poor quality; In the crushing and mixing process of some brick pressing devices, there are problems of poor stability, large shaking of the device, and insufficient crushing and mixing; there is still no pre-compacting step in the brick pressing process, resulting in the size of the bricks that are subsequently pressed out. It meets the standard; after the brick pressing is completed, the bricks are often taken out manually, without the function of automatically ejecting the mold, which consumes a lot of manpower and material resources
