s3: in the process that the blade plate (12) drives the blanking pipe (2) to rotate, the blanking pipe (2) drives the annular pipe (15) to synchronously rotate through the sliding block (162) and the connecting rod (161) which are clamped with the clamping groove (164), when the carbonized materials in the blanking pipe (2) are excessive, the carbonized materials can squeeze the connecting rod (161), so that the connecting rod (161) pushes the sliding block (162) to squeeze the spring (163), the sliding block (162) stretches out of the clamping groove (164), and the sliding block (162) is ensured to slide in the T-shaped groove (16);
S4: after the carbonization material is activated, the discharge opening (11) is opened, so that the carbonization material in the cooling belt (114) is taken out, at the moment, the carbonization material in the activation belt (113) is dropped into the cooling belt (114), the discharge opening (11) is closed, at the moment, the carbonization material in the supplementary carbonization belt (112) is dropped into the activation belt (113) area, the carbonization material in the preheating belt (111) is dropped into the supplementary carbonization belt (112) area, the worker adds the carbonization material into the carbonization material from the feeding tank, and therefore the carbonization material in the preheating belt (111) is supplemented, after the activation of the carbonization material in the activation belt (113) is completed, at the moment, the carbonization material after the activation in the cooling belt (114) is cooled, and the worker takes out the carbonization material in the cooling belt (114) to obtain the carbonization material;
s5: when the activated carbonized material is taken out, firstly removing dust in activated pores of the carbonized material by a negative pressure adsorption box, and then drying the carbonized material with the dust removed, thereby finally obtaining the required activated carbon.
