Description

Technical Field

[0001] The utility model relates to the technical field of waste treatment, in particular to a typical high-temperature collaborative treatment device for heavy metal hazardous waste. Background Art

[0002] High-temperature co-disposal equipment for heavy metal hazardous waste usually refers to high-temperature thermal treatment systems such as incinerators or pyrolysis furnaces. These equipment can effectively decompose and oxidize hazardous waste containing heavy metals under high temperature conditions, thereby achieving harmless treatment and resource utilization. The process includes: Pretreatment: sorting, crushing, drying and other pretreatment of hazardous waste to meet the requirements of incineration; Incineration / pyrolysis: In a high-temperature (800-1200℃) incinerator or pyrolysis furnace, organic matter is completely decomposed and oxidized, and heavy metals are enriched in the residue; Waste heat utilization: The exhaust gas of the incinerator passes through a heat exchange system to recycle the heat; Dust removal / purification: The flue gas of the incinerator passes through a multi-stage purification system to remove pollutants such as acidic gases, heavy metals and particulate matter; Slag treatment: Heavy metals are enriched in the incineration residue, which needs to be further stabilized for landfill or resource utilization.

[0003] Among them, the crushing operation in the pretreatment stage is an important part of hazardous waste pretreatment. The main purpose is to crush large pieces of solid hazardous waste into smaller particles to meet the requirements of the subsequent heat treatment process. After the existing crushing equipment treats the hazardous waste, the output of the crushed materials requires a special control system or manual control. No matter which control method is used, it requires a separate power source and power structure to cooperate with each other, and lacks effective connection with the crushing step;

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a typical high-temperature co-treatment equipment for heavy metal hazardous wastes. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a typical heavy metal hazardous waste high-temperature coordinated disposal equipment, including a crushing box and a high-temperature incineration box; the top of the crushing box is connected with a feed port, and typical heavy metal hazardous waste is input into the crushing box along the feed port for crushing treatment; a crushing mechanism is arranged to rotate inside the crushing box, and the crushing mechanism is connected to a rotating power system outside through an auxiliary rotating shaft, and the operation of the rotating power system directly drives the crushing mechanism to rotate and crush the input heavy metal hazardous waste into particles; the bottom of the crushing box is connected with a crushed particle output pipe, and the waste particles processed by the crushing mechanism are transferred to the crushed particle output pipe under gravity; the bottom of the crushed particle output pipe is connected with a high-temperature incineration box, and the waste particles passing through the crushed particle output pipe are transferred to the high-temperature incineration box for incineration treatment; an opening and closing component is arranged inside the crushed particle output pipe, and the opening and closing component is used to control the opening and closing of the crushed particle output pipe, That is, the waste particles are controlled to pass through the crushed particle output pipe. A lifting and stretching component is connected to one side of the opening and closing component, and the lifting and stretching component drives the opening and closing component to operate. When the lifting and stretching component descends, it drives the opening and closing component to move laterally outward, and the crushed particle output pipe is opened. When the lifting and stretching component rises, it drives the opening and closing component to move laterally toward the inside of the crushed particle output pipe, and the crushed particle output pipe is closed. The lifting and stretching component is connected to the rotary power system, and the rotary power system controls the lifting and stretching component to move up and down intermittently, that is, while it drives the crushing mechanism to crush the heavy metal hazardous waste, it drives the lifting and stretching component to drive the opening and closing component to control the intermittent opening and closing of the crushed particle output pipe, and cooperates with the action of gravity to continuously and intermittently control the crushed waste particles to be automatically output downward. Compared with the existing output structure, it utilizes crushing kinetic energy, saves resources, and is automatically operated, and is interconnected with the crushing steps to achieve efficient crushing and output pretreatment of heavy metal hazardous waste.

[0007] Compared with the prior art, the beneficial effect of the utility model is that the opening and closing of the crushed particle output pipe is integrated with the operation of the crushing mechanism inside the crushing box, that is, while the crushing mechanism rotates, the opening and closing of the crushed particle output pipe is intermittently controlled, and then with the action of gravity, the processed waste particles are automatically transmitted downward, realizing automatic timed feeding, saving manpower and additional power costs for the opening and closing operations of the crushed particle output pipe, and reducing the processing cost of the equipment to a certain extent.

A lifting and stretching component is connected to one side of the opening and closing component. The lifting and stretching component drives the opening and closing component to operate. When the lifting and stretching component descends, it drives the opening and closing component to move laterally outward, and the crushed particle output pipe 12 is opened.
