The existing incineration device has the problem of insufficient combustion generally, and the analysis and induction reasons mainly comprise: firstly, the whole oxygen supply amount in the incinerator is insufficient. The flow rate of the air introduced into the furnace is smaller; secondly, the oxygen in the incinerator is unevenly distributed. The arrangement of the blast channels of most incineration devices is uneven, so that the oxygen in the furnace is unevenly distributed; third, accurate feeding is not realized. When the materials are burnt, the oxygen consumption of the incinerator is different due to the different burning degrees of the materials at different positions; fourth, ash covers the objects to be burned to prevent contact with oxygen.

The air inlet is single and above the flame, and oxygen supply according to the combustion degree can not be realized. The burning cylinder and the helical blade are matched to rotate to stir and turn materials, but the stirring amplitude is relatively large, the materials are easy to cover flame at the initial ignition stage to cause ignition failure, meanwhile, ash is not separated from the materials, and can be mixed in the materials when stirring and turning, contact between the materials and air can be blocked, and the burning is insufficient. Chinese patent (201310699342.2) and Chinese patent (201410466211.4) respectively disclose a rotary double-roller incinerator and a rotary vertical garbage incinerator, and the arrangement of the designed incinerator cylinder/incinerator does not realize the separation of ash and objects to be combusted, and still has the problem of insufficient combustion.
Aiming at the problems, the invention provides the following solution thought: on one hand, oxygen is supplied according to different combustion degrees and oxygen is supplied accurately according to the needs; on the other hand, ash and the objects to be burnt are separated in time. . The inner container is arranged to be open-type, so that the discharging is facilitated. And the spiral boss arranged on the inner wall of the liner can realize stirring and ventilation functions, so that waste gas and fresh air are timely isolated, objects to be combusted and waste residues are timely separated, the discharge capacity of toxic gases generated due to insufficient combustion is reduced, and meanwhile, the material combustion efficiency is improved.
