Crushing and regenerating process and device for waste and defective concrete

Abstract

The invention discloses a crushing and regenerating process and device for waste and defective concrete. The device comprises a U-shaped support, a multi-stage vibrating screen and a cabinet body, wherein a conveying belt body is arranged at the top of the U-shaped support through a fixing frame, a supporting frame is arranged at the top of the U-shaped support through a bolt, a fixing plate is welded to the end of the supporting frame, a lengthened screw rod is arranged on the fixing plate through a threaded sleeve, a storage box is arranged at one end of the conveying belt body, the multi-stage vibrating screen is arranged at the lower end of the storage box through a fixing frame, and the cabinet body is arranged at a powder outlet in the bottom of the multi-stage vibrating screen through a bolt. According to the crushing and regenerating process and device for waste and defective concrete, mineral powder in crushed recycled materials can be conveniently recycled, stored and utilized in a centralized mode, the overall recycling process shows the energy-saving and environment-friendly design concept, the quality of regenerated concrete can be improved, operation is convenient, the manufacturing cost is low, the automation degree is high, and manpower and material resources are effectively saved.

Description

technical field [0001] The invention belongs to the technical field of concrete regeneration, and in particular relates to a process and device for crushing and recycling waste and defective concrete. Background technique [0002] Recycled concrete means that waste concrete blocks are crushed, cleaned and graded, mixed with gradation in a certain proportion, partially or completely replaced by natural aggregates (mainly coarse aggregates) such as sand and gravel, and then added with cement, water, etc. new concrete. Recycled concrete can have the following situations according to the combination of aggregates: all aggregates are recycled aggregates; coarse aggregates are recycled aggregates, fine aggregates are natural sand; coarse aggregates are natural gravel or pebbles, fine aggregates The raw materials are recycled aggregates; recycled aggregates replace part of the coarse or fine aggregates. [0003] Since the performance of recycled aggregates is worse than that of n...
