[0002] Hazardous solid waste, referred to as hazardous waste, refers to waste included in the national hazardous waste list or identified as having hazardous waste characteristics according to the national hazardous waste identification standards and identification methods.

[0003] Hazardous properties refer to corrosiveness, acute toxicity, leaching toxicity, reactivity, infectiousness, nuclear radioactivity, etc. Hazardous wastes must be handled safely and properly because they can have serious impacts on the environment and even the human body. According to national and local environmental protection laws and regulations: units that generate hazardous wastes must centrally handle hazardous wastes, assign special personnel to be responsible for collection and management, and set up special containers for storage of hazardous wastes to be transported. Hazardous wastes must be collected, transported, handled and processed by units with corresponding qualifications. Incineration is undoubtedly a more reliable, economical, safe and effective means, so incineration devices are generally used for treatment.

[0004] The existing hazardous waste incinerators generally use ordinary meshes for the slag penetration mechanism. When the diameter of the burned ash is large, it is easy to clog the mesh, affecting the incineration efficiency. Therefore, how to develop a new type of hazardous waste incinerator has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0008] Furthermore, the sprocket is arranged on the outside of the box.

[0009] Furthermore, a stirring mechanism is provided in the incineration chamber, and the stirring mechanism is driven by a reduction box at the top of the box body.

[0010] Furthermore, the stirring mechanism includes a rotating shaft and a rotating sleeve, the rotating shaft is provided with a first stirring rod, and the rotating shaft cooperates with the first motor through the gear in the reduction box; the rotating sleeve is sleeved on the circumferential surface of the rotating shaft, the rotating sleeve is provided with a second stirring rod, and the rotating sleeve cooperates with the second motor through the gear of the reduction box.

[0011] Furthermore, a feed pipe cooperating with the top end of the incineration chamber is arranged on the side wall of the box body; a burner cooperating with the lower end of the incineration chamber is arranged on the side wall of the box body.

[0012] Furthermore, a ventilating port cooperating with the burner is arranged at the lower end of the box body; and a flue is arranged at the top end of the box body.
