Mechanical equipment for preparing regenerated sand-gravel material by using construction waste particles

Abstract

The invention discloses mechanical equipment for preparing regenerated sand-gravel material by using construction waste particles. The mechanical equipment comprises a grinding box, a stirring barrel, a screening device and a material pushing barrel, wherein the grinding box and the stirring barrel are both fixedly connected with a supporting frame, the screening device and the material pushing barrel are both located at the upper end of a fixing frame, a grinding motor is arranged on one side of the middle of one end of the grinding box, the fixing frame and a movable opening plate are connected in a matched mode through a plurality of first hydraulic telescopic rods, a material collecting hopper is arranged between the lower end of the movable opening plate and one side of the upper end of the material pushing barrel, a material pushing motor is arranged at the position, located on one side of the upper end of the fixing frame, of one end of the material pushing barrel, a transmission shaft extending into the material pushing barrel is arranged at one end of the material pushing motor, a plurality of material pushing spiral blades are arranged on the position, located inside the material pushing cylinder, of the transmission shaft, and the end, away from the supporting frame, of the fixing frame is provided with a waste box. The mechanical equipment has the beneficial effects that construction waste can be classified and reused conveniently, waste of resources and pollution to the environment are reduced, the waste is recycled, and the resources are saved while the environment is protected.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a mechanical device for producing regenerated sand and gravel by using construction waste particles. Background technique [0002] Building materials include concrete, mortar and cement bricks, etc., which are widely used. The basic production materials are three major raw materials: cement, sand and stone. The mining and supply of sand, stone and cement raw materials required for construction will continue to cause irreversible damage to the environment. impact, construction waste cannot be effectively recycled, which is not only a waste of resources, but also damages the ecological environment, especially the concrete that will be discarded when painting walls, and the existing construction waste treatment technology cannot effectively treat the cement sand cemented together The stone particles are decomposed into independent sand, stone and cement stone fines, a...

[0002] Building materials include concrete, mortar and cement bricks, etc., which are widely used. The basic production materials are three major raw materials: cement, sand and stone. The mining and supply of sand, stone and cement raw materials required for construction will continue to cause irreversible damage to the environment. impact, construction waste cannot be effectively recycled, which is not only a waste of resources, but also damages the ecological environment, especially the concrete that will be discarded when painting walls, and the existing construction waste treatment technology cannot effectively treat the cement sand cemented together The stone particles are decomposed into independent sand, stone and cement stone fines, and the recycled sand and gravel aggregate produced by it is actually just broken cement-bonded sand particles and cement-bonded sand and gravel particles, which are still cement and sand. Composite material particles of stone, the surface of the composite material particles not only has a large number of fine cracks, sharp edges and corners
