Classification device for plastic garbage treatment and recovery

Abstract

The invention relates to the field of garbage classification equipment, in particular to a classification device for plastic garbage treatment and recovery. The classification device comprises a machine body and a classification cavity located in the machine body and provided with an upward opening, moving grooves in bilateral symmetry are formed in the end wall of the upper side of the classification cavity, baffles capable of moving left and right are arranged in the moving grooves, and first electromagnets which are in bilateral symmetry and attract each other after being powered on are arranged on the outer walls of the baffles and the moving grooves. The invention provides the classification device for plastic garbage treatment and recovery. According to the classification device, the amount of harmful metal elements such as mercury in the plastic garbage is detected through a metal detector, the harmful metal elements are classified into the corresponding garbage baskets to be treated through rotation of classification wheels, the plastic without metal parts is sealed in a closed space after being crushed, nutrient solution is supplied to plastic decomposition microorganisms in the plastic at intervals through extrusion of sponge blocks, the plastic containing metal is heated and decomposed through crushing and heating and then recycled in a unified mode, and the recyclability of the device is guaranteed.

Description

technical field [0001] The invention relates to the field of garbage sorting equipment, in particular to a sorting device for processing and recycling plastic garbage. Background technique [0002] At present, the global disposal methods for waste plastics include landfill, incineration, microbial decomposition and other methods. The incineration method is not suitable for popular treatment due to the large amount of harmful gas and low efficiency. The landfill method is very difficult due to the refractory nature of plastics. It is easy to cause secondary pollution and is not suitable for large-scale use. Microbial decomposition is relatively more environmentally friendly and safe. It only needs a closed space and a suitable temperature to achieve it. However, most plastic products are mixed with metal objects. Harmful elements such as mercury are not conducive to the growth of bacteria, and the growth of bacteria requires regular supply of nutrient solution to suit their g...

[0002] At present, the global disposal methods for waste plastics include landfill, incineration, microbial decomposition and other methods. The incineration method is not suitable for popular treatment due to the large amount of harmful gas and low efficiency. The landfill method is very difficult due to the refractory nature of plastics. It is easy to cause secondary pollution and is not suitable for large-scale use. Microbial decomposition is relatively more environmentally friendly and safe. It only needs a closed space and a suitable temperature to achieve it. However, most plastic products are mixed with metal objects. Harmful elements such as mercury are not conducive to the growth of bacteria, and the growth of bacteria requires regular supply of nutrient solution to suit their growth to achieve the corresponding effect. Therefore, it is necessary to design a sorting device for plastic waste treatment and recycling to improve the above problems
