Cement curing line mixing stirrer

Abstract

The invention discloses a cement curing line mixing stirrer, and relates to the field of cement curing equipment. The cement curing line mixing stirrer comprises a power device, a stirring box, a bearing box, a stirring shaft, an inner magnetic rotor, an outer magnetic rotor and a distance sleeve. The distance sleeve is arranged in the outer magnetic rotor, the inner magnetic rotor is arranged inthe distance sleeve, and the outer magnetic rotor is coupled with the inner magnetic rotor. One end of the outer magnetic rotor is fixedly connected with the output end of the power device, the innermagnetic rotor is fixedly connected with one end of the stirring shaft, the other end of the stirring shaft penetrates through the stirring box, and a movable seal is arranged between the stirring shaft and the stirring box. The bearing box sleeves the stirring shaft, one end of the bearing box is fixedly connected with the open end of the distance sleeve, the other end of the bearing box is fixedly connected with the stirring box, and sealing gaskets are arranged between the stirring box and the bearing box and between the distance sleeve and the bearing box. The sealing effect of the mixingstirrer is reliable, the problem of radioactive waste leakage is completely solved, the life health of staff is guaranteed, and meanwhile the cement curing line mixing stirrer is reasonable in structural design, convenient to dismount and mount and easier to overhaul and maintain.

Description

technical field [0001] The invention relates to the field of cement curing equipment, in particular to a cement curing line mixing agitator. Background technique [0002] In the fields of nuclear power, petrochemical, medicine and other fields, some radioactive wastes are usually produced. The radioactive wastes include waste concentrates, waste resins, waste filter cores, etc. These radioactive wastes need to be processed and transported to the radioactive disposal site after meeting the transportation conditions. dispose of. At present, the treatment of the above-mentioned radioactive waste usually adopts the cement solidification method, and the radioactive waste particles are respectively wrapped and hardened by cement to reduce their harm. In order to make the above-mentioned wrapping process uniform and thorough, a mixer is usually required. [0003] The traditional mixing agitator is usually directly driven by the power device to one end of the mixing shaft, and the...

AI Technical Summary

Problems solved by technology

However, the reliability of the dynamic seal is poor, and its effective sealing time period is short, and leakage often occurs, especially for radioactive substances, which will form a toxic and harmful environment around the equipment after leakage, which makes the maintenance of the equipment very difficult. It is inconvenient and poses a great threat to the life and health of maintenance personnel.
