Embodiment Construction

[0018] Such as figure 1 As shown, a concrete mixing plant using building waste as raw materials includes an aggregate supply system, a weighing system, a lifting system, a mixer system, and a control system 240. The aggregate supply system includes a primary crusher 11 and a double-layer vibration screener. , The conveying unit, the secondary crusher 12 and the receiving water tank 4. The primary crusher 11 performs primary crushing of the construction waste transported by the transport vehicle to obtain primary aggregates, and sends the primary aggregates to the double-layer vibrating screener. The vibrating screening machine includes an upper vibrating screening unit 32 and a lower vibrating screening unit 31. The screen mesh size of the upper vibrating screening unit 32 is larger than the screening mesh size of the lower vibrating screening unit 31. The conveying unit includes a first conveyor belt 21 and a second conveyor belt 22. And the third conveyor belt 23, the primary ...

Abstract

The invention discloses a concrete mixing station made of building waste. The concrete mixing station comprises an aggregate feeding system, a weighing system, a lifting system, a mixer system and a control system. The aggregate feeding system comprises a primary pulverizer, a double-deck vibrating screening machine, a conveying unit, a secondary pulverizer and a receiving water tank. The weighing system is a belt weigher. The lifting system is a bucket lifter. The conveying unit comprises a first conveying belt, a second conveying belt and a third conveying belt. The concrete mixing station is made of the building waste, and secondary utilization of the building waste is achieved; not only is the burying amount of the building waste decreased, but also environmental pollution is relieved, and raw materials can be provided for concrete production, so that the large-scale production requirement for concrete is met.

Description

Technical field: [0001] The invention relates to the technical field of concrete production, in particular to a concrete mixing station using building waste as raw materials. Background technique: [0002] With the rapid development of the city, while a large number of new buildings are being built, a large number of old buildings will also be demolished. During this process, a large amount of construction waste will be produced. The so-called construction waste usually refers to the mixture of garbage and waste. Together with concrete blocks, waste wood, asphalt concrete blocks, etc. The current construction waste treatment process is complicated and difficult, and it is usually landfilled. On the one hand, the unreasonable landfill of construction waste will cause environmental pollution and adversely affect the public's physical and mental health; on the other hand, it will also cause the waste of valuable resources, making it difficult to reuse construction waste. Summary o...
