Description

Automatic treatment system for building decoration garbage and working method thereof

Technical Field

The invention belongs to the technical field of environmental protection, and particularly relates to an automatic treatment system for building decoration garbage. The invention also relates to a working method of the automatic treatment system for the building decoration garbage.

Background

The construction and decoration garbage refers to a general name of dregs, waste concrete, waste bricks and stones and other wastes generated in the production activities of people in the construction industry such as demolition, construction, decoration, repair and the like. The construction waste can be classified into engineering residue soil, decoration waste, demolition waste, engineering slurry and the like according to the production source; the construction waste can be classified into slag, concrete blocks, broken stone blocks, broken bricks and tiles, waste mortar, slurry, asphalt blocks, waste plastics, waste metals, waste bamboo and wood and the like according to the composition.

At present, no treatment method for effectively recycling decoration garbage exists in the market, and the traditional decoration garbage treatment method is to directly bury the decoration garbage after the decoration garbage is manually sorted and the decoration garbage cannot be effectively utilized. The resource utilization degree is low, and the inorganic matters with higher utilization value in the decoration garbage can not be effectively utilized. The decoration rubbish composition is complicated, and the unit weight is low, and the manual sorting need pave the decoration rubbish, and area is big, and manual sorting intensity of labour is high, and the inefficiency of letter sorting. The landfill disposal cost is high, and the landfill disposal easily causes land waste and environmental pollution. A small number of manufacturers explore a recycling treatment method of decoration garbage, and the method generally comprises manual sorting, bag breaking, screening and winnowing. The broken bag generally adopts the handling mode similar to the broken bag of domestic waste, and the fitment rubbish is no less than domestic waste, and very big part fitment rubbish exists with the form of weaving bagging-off when collecting, and some just bundle is good, and the braided bag is not like the plastic bag breakable, and has the higher concrete piece of hardness, rubble piece etc. in the fitment rubbish of bagging-off, want to effectively pour out or break the bag with the thing in the bag, the higher concrete piece of hardness and rubble piece are hardly dealt with in batches to conventional domestic waste treatment equipment, and damage the blade easily, and compulsory crushing equipment such as shredder, first throughput is limited. The second pair of concrete blocks and crushed stones with higher hardness is easy to reduce the treatment capacity and damage the blades, so the overall effect of the recycling treatment of the decoration garbage is poor. Compared with a domestic garbage disposal method, the disposal method can only treat decoration garbage with less light substance content or simpler light substance components, has more complex components, and has poor disposal effect and low efficiency of the bagged decoration garbage. The application range is narrow;

because the decoration garbage contains a large amount of bagged decoration garbage, the hardness of concrete blocks in the bags is high, forced bag breaking equipment is easy to cause blade damage, the concrete blocks/stones are required to be shredded by using shredding equipment, the equipment is easy to damage, the extrusion type crushing equipment is difficult to meet the bag breaking requirement, and treated bagged materials still do not have the forced bag breaking technical requirement. Substances with longer length (such as banners and the like) in the decoration garbage are difficult to be effectively separated; the bagged decoration garbage is screened or winnowed without being effectively broken and poured out, the effects of winnowed separation and screening are poor, and the requirement of large-batch decoration garbage resource disposal production cannot be met. Inorganic matters generated in the treatment process contain more slender matters, so that the method is not suitable for transmission equipment in a decoration garbage recycling treatment line or has high treatment cost.
