Embodiment 1

[0040] figure 1 It is a structural block diagram of a mineralized waste sorting system provided in Embodiment 1 of the present invention.

[0041] Such as figure 1 As shown, the mineralized waste sorting system provided by the embodiment of the first aspect of the present invention includes a sequentially connected manual sorting system, a screening system and a sorting system;

[0042] The manual sorting system sorts out waste wood, plastics and rubber;

[0043] The screening system screens out coarse-grained materials with larger diameters and fine-grained materials with smaller diameters;

[0044] The sorting system includes a coarse-grained sorting system and a fine-grained sorting system, the coarse-grained sorting system screens out the plastic in the coarse-grained material, and the fine-grained sorting system screens out the fine-grained material The fine aggregate 10 inside is screened out, and the fine aggregate 10 is used for building materials.

[0045] The scr...

Embodiment 2

[0079] In this embodiment two, an electrical control system is also provided. The electrical control system is an important part of the entire treatment system. Since the construction environment of the garbage disposal site is far worse than that of a construction site, it is generally open-air, and workers need to be equipped with protective masks. The requirements for safe operation are higher than those for factories. In order to reduce the number of operators and realize the automation of the waste disposal production line, the electrical system is equipped with a PLC programmable controller to meet the automation requirements of the production line startup sequence and workflow.

[0080] Since the feeder, belt conveyor, screening system and sorting system are sensitive to real-time changes in the state, composition and moisture content of the materials being processed, they have strict requirements on the rotational speed or line speed. If certain measures are not taken, ...

Abstract

The invention provides a sorting system of mineralized refuse and a sorting process of the mineralized refuse, and relates to the field of mineralized refuse treatment. The sorting system includes anartificial sorting system, a screening system and a sorting system which are connected in turn; the artificial sorting system sorts out waste wood, plastic and rubber; the screening system screens outcoarse particulates with larger diameter and fine particulates with smaller diameter; the sorting system includes a coarse particulate sorting system and a fine particulate sorting system, the coarseparticulate sorting system is used for sieving out the plastic in a coarse particulate material, and the fine particulate sorting system sieves out fine aggregates in a fine particulate material. Thesorting system of the mineralized refuse can sort out the plastic and the fine aggregates through the coarse particulate sorting system and the fine particulate sorting system, and screen out the available materials such as the plastic, metal, humus soil and the like. The problem of low screening quality caused by complex composition and high humidity of the mineralized refuse is solved, and thesystem has the advantages of good screening quality, convenient screening and the like.

Description

technical field [0001] The invention relates to the field of mineralized garbage treatment, in particular to a mineralized garbage sorting system and a mineralized garbage sorting process. Background technique [0002] Domestic waste can be stabilized after several years of biodegradation in the landfill, and it is a general term for a kind of non-toxic and harmless waste formed. After 8-10 years of landfill waste (more than 10-15 years in the northern region), the easily degradable substances in it will be completely degraded, and the final content will be reduced to less than 5%, and the amount of leachate and gas will be little or no. The surface settlement is very small (less than 1cm / a), it can be considered that the landfill has reached stabilization at this time, and the garbage at this time can be called mineralized garbage. [0003] Because mineralized waste has been buried underground for many years, it has the characteristics of complex composition, high humidity...
