At present, a chemical making tank or a reaction kettle used in the processes of high-temperature and high-pressure cooking, hydrolysis, chemical making, harmless treatment of culture waste and slaughter by-products and chemical making processing is generally of a through shaft structure with a long shaft length in a tank or a kettle. The processing process of the middle shaft is to process and form the whole through shaft, then weld the drum disc and stir the wings on the shaft body of the middle shaft, in practice, the middle shaft is easy to deform due to welding, so that the shaft heads at two ends of the middle shaft can not ensure concentricity, the sealing part is assembled at the shaft heads at two ends, if the concentricity of the shaft heads at two ends can not be ensured, the middle shaft can jump in the rotating operation process of the middle shaft, the sealing effect of the shaft heads at two ends is further influenced, and finally the packing abrasion phenomenon is very serious.

At present, the sealing measure for shaft heads at two ends of a center shaft is to adopt a process of manually pressing a packing by pressing an inner sleeve, an outer sleeve, a packing and a gland at a head sealing shaft and pressing by using the gland. If shaft end air leakage occurs, manual pressing or packing adding and replacing is adopted, the operation is troublesome and the efficiency is low. In addition, the packing gland compression degree is not easy to master, the compression degree is insufficient and cannot achieve the sealing effect, and the compression degree is too large, so that the loads of a motor and a speed reducer are easily increased, and a main shaft is also abraded. In particular, the packing belongs to a wearing part, and the frequency of wearing and replacing is higher.
