Embodiment 1

[0027] Under the condition that the room temperature is about 27°C, the mixed solid waste first passes through a low-temperature thermostatic chamber with a temperature of 27°C for 5 minutes, and the temperature of the mixed solid waste is completely kept at 27°C. At this time, the main conveyor belt transports the mixed solid waste to a high-temperature room with a temperature of 55 °C, and collects data through a PC-based data acquisition system. The sensor data shows that metal materials such as stainless steel, lead, aluminum, gold, copper, silver, etc. will rise by 15°C within 1.5-4min, and the heating rate is 3.75-10°C / min. At this time, several groups of solid waste sorting hands can sort out metal materials such as stainless steel, lead, aluminum, gold, copper, silver, etc., and move them to the secondary conveyor belt for conveying metal materials. The auxiliary conveyor belt then transports the metal material to the metal material collection room.

Embodiment 2

[0029] Under the condition that the room temperature is about 27°C, the mixed solid waste first passes through a low-temperature thermostatic chamber with a temperature of 27°C for 5 minutes, and the temperature of the mixed solid waste is completely kept at 27°C. At this time, the main conveyor belt transports the mixed solid waste to a high-temperature room with a temperature of 55 °C, and collects data through a PC-based data acquisition system. The sensor data shows that inorganic materials such as glass, soil, concrete, etc. will rise by 15°C within 5.5-8.5min, and the heating rate will be 1.76-2.72°C / min. At this time, several groups of solid waste sorting hands can sort inorganic materials such as glass, soil, concrete, etc., and move them to the secondary conveyor belt for transporting inorganic materials. The auxiliary conveyor belt then transports the inorganic material to the inorganic material collection chamber.

Embodiment 3

[0031] Under the condition that the room temperature is about 27°C, the mixed solid waste first passes through a low-temperature thermostatic chamber with a temperature of 27°C for 5 minutes, and the temperature of the mixed solid waste is completely kept at 27°C. At this time, the main conveyor belt transports the mixed solid waste to a high-temperature room with a temperature of 55 °C, and collects data through a PC-based data acquisition system. The sensor data shows that organic polymer materials such as rubber, [polymer] polypropylene, and epoxy resin rise by 15°C within 10-14min, and the heating rate is 1.07-1.5°C / min. At this time, several groups of solid waste sorting hands can sort out organic polymer materials such as rubber, [macromolecule] polypropylene, epoxy resin, etc., and move them to the secondary conveyor belt for conveying organic polymer materials. The secondary conveyor belt then transports the organic polymer material to the organic polymer material coll...

Abstract

The invention relates to a solid waste sorting process based on thermal conductivity difference of different materials. The solid waste sorting process is capable of sorting different types of solid wastes through a simple process and aims to solve the problems that the existing solid waste sorting process is incapable of sorting solid wastes with maximum benefit due to reasons such as complex sorting process flow, single classification object, high equipment cost, complex technique and the like. Temperature sensors are taken as the core of the solid waste sorting process provided by the invention, a data acquisition system based on a PC (Personal Computer) acquires and processes the temperature of each point in the process flow, and according to heat absorbing / releasing models of different materials, a computer controller is used for automatically controlling the temperatures of a high constant temperature chamber and a low constant temperature chamber and the temperature recognition range of the temperature sensors on different manipulators, therefore, the solid waste sorting process is capable of efficiently sorting the different solid wastes. Compared with other conventional sorting processes, the whole process expands the range of the sortable solid wastes, simplifies the sorting steps and develops a new way for sorting the solid wastes.

Description

1. Technical field [0001] The invention relates to a treatment process for sorting solid waste, in particular to a solid waste sorting process based on different thermal conductivity of different materials. 2. Background technology [0002] Solid waste is mainly divided into three categories: industrial and mining solid waste, domestic garbage and other solid waste. The main components of industrial and mining solid waste include waste rock, metal, waste wood, plastic, etc., and the main components of domestic waste are plastic, rubber, metal, kitchen waste, paper scraps, etc. [0003] In the past, the methods of solid waste treatment were mainly through physical means (such as crushing, compression, drying, evaporation, incineration, etc.) or biochemical effects (such as oxidation, digestion, decomposition, absorption, etc.) to reduce its volume and accelerate its natural purification. the process of. Household waste treatment methods are mainly landfill (a kind of solid ...
