Description

Special crushing and material separation production line process for module-movable building solid waste
Technical Field
The invention belongs to the field of decoration and construction waste resource recycling.
Background
For decades, no real professional core technical equipment is put into market for resource utilization of decoration garbage and construction garbage in China, and the mine crusher is used for replacing the equipment. Experts point out in the working meeting of the national fixed construction waste disposal technical regulation: the current domestic construction waste treatment equipment and process are as follows: the mining machinery and the machine-made sandstone production process and equipment are directly adopted, the equipment adaptability is poor, the environmental protection facility is imperfect, part of project dust is discharged out of order, the energy consumption index is lacked, the water and electricity consumption for production is large, professional planning and design are lacked, the secondary environment pollution is caused by unreasonable process of part of projects, and the development of resource utilization of the construction waste is seriously influenced. "
The difference between mining machinery and decoration and construction waste resource utilization machinery is as follows: 1. the operation environment is different, and the mining operation is generally performed in mountainous areas; the working environment of the decoration and construction waste resource utilization is generally in cities or suburbs. 2. The difference in working conditions is that the mining machinery processes ores with single components, and the decoration and construction waste machinery processes wastes with complex components. 3. Functionally distinct, the mining machine has two functions, one for single hard material ore crushing and the other for ore screening. 4. The method has the defects that the national state starts to execute the technical standard for treating the construction waste in 2019, 11 and 1, and the technical standard of the national state is specifically stipulated and is matched with a dust remover and used for controlling the noise; the content of foreign matters in the recycled aggregate is not more than 5 percent. The two functions of the mining machine are in contrast to the state technical standards.
Mining machinery is used for construction waste treatment, and the drawback lies in: firstly, the yield of the recycled aggregate is greatly reduced. Secondly, an environment protection system is not provided, dust generated in operation cannot be collected, so that economic value loss and secondary pollution to the environment are caused, and negative effects are caused to the natural ecological environment. Thirdly, the moving mode of the mining machinery is not suitable for decoration and treatment of construction waste, and the mining machinery is provided with power (an engine) to automatically travel (a crawler belt or a tire) due to the operation requirement of mining mountain areas; the decoration and the construction waste treatment are not in mountainous areas, and the required power is more environment-friendly and economical than fuel oil when the decoration and the construction waste treatment are in cities or suburbs. And fourthly, a foreign matter separation system is not arranged, the treated construction waste is large waste and changed into small waste, the construction waste can only be used for low-quality backfill, and the quality of the product is known by using the 'recycled aggregate' with the foreign matter exceeding the standard to produce recycled bricks.
In view of the above, under such background, the invention is creating a dedicated equipment/production line which is suitable for decoration and resource utilization of construction waste and has an autonomous core technology.

Remarking: the terms are explained and annotated
The decoration garbage and the construction garbage are produced and processed into machinery used for 'renewable resources', and the machinery is called as 'upstream equipment'. The machine used for producing and processing the 'renewable resources' into 'renewable products' is called as 'downstream equipment'. The invention provides a technological process of a special crushing and material separating production line for module moving type building solid waste, belonging to one of upstream equipment.
The invention creates a technological process of a special crushing and material separation production line for module movable type building solid wastes, which can add not more than 30% of decoration wastes due to the mechanical properties of a feeding and mutation crusher, two super separators and a waste classification device, and if the decoration wastes contain dangerous wastes, the artificial intervention is needed. If the decoration garbage is more than 30 percent, another special 100 percent decoration garbage resource utilization technology and equipment are selected.
