Description

Technical Field

[0001] The utility model relates to the technical field of building waste briquette bricks, in particular to a raw material screening device for producing building waste briquette bricks. Background Art

[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other wastes generated during the construction, laying, demolition and repair of various buildings, structures, pipelines, etc. by construction units or individuals. At present, the amount of construction waste in my country has accounted for 30% to 40% of the total urban waste. Construction waste is a kind of waste with a relatively complex composition. It generally includes discarded concrete, bricks, wood, plastic, fine steel bars, metal, cloth, etc. Now construction waste is also used as raw material for brick making. Construction waste is sorted, crushed and screened as recycled aggregate, and is measured and mixed with ecological cement (mainly prepared from solid waste such as high-calcium fly ash, slag and desulfurized gypsum), antifreeze additives and water in proportion. After processing by construction waste treatment equipment, the construction waste can be used to produce high-performance standard bricks by cement brick making machine.

A first opening is provided on the inner wall of the barrel body, and a suction fan is fixedly connected to the bottom of the first opening. The lower end of the barrel body is provided with multiple grooves, and pillars are provided within the grooves. The utility model can perform reciprocating screening of construction waste by providing the first screening mechanism, leaving larger construction waste on the first screen plate; by providing the second screening mechanism, an electromagnet can absorb ferrous materials; by providing the suction fan, lighter construction waste can be removed; and by providing the third screening mechanism, construction waste can be reciprocated and screened, achieving a better screening effect. When the barrel body vibrates, the telescopic rod, the first spring, and the second spring are forced to contract, which can play a role in buffering and shock absorption, thereby reducing noise.

[0004] The above technical solution uses an open screening mechanism to screen construction waste. During the screening process, large particles of construction waste may fall together with small particles of construction waste, which requires manual selection, greatly reducing work efficiency.
