Abstract

A high-temperature-resistant dry friction permanent magnet maglev stirrer comprises a driving device, a transmission shaft and a stirrer barrel component. The stirrer barrel component includes a stirrer barrel, a stirrer barrel upper cover plate fixed to an upper opening of the stirrer barrel, and a stirrer bottom flange fixed to a lower opening of the stirrer barrel; a bearing block is fixed to the upper end face of the stirrer barrel upper cover plate; a support is fixed onto the bearing block; the upper portion, middle and lower portion of the transmission shaft are sequentially and rotationally supported in the support, the bearing block and the stirrer bottom flange via rolling bearings respectively; the upper end of the transmission shaft is provided with a transmission flange fixedly connected to the output end of the driving device; the transmission flange is rotationally connected with the support via a maglev bearing component in a supported manner. The high-temperature-resistant dry friction permanent magnet maglev stirrer has the advantages that great axial force is borne by means of a maglev bearing non-contact mode, a high-temperature-resistant dry friction alloy rolling bearing is used to assist in supporting the transmission shaft, the problem that an existing stirrer has short life and high cost in a heavy-load high-temperature dry friction environment is solved, fewer maintenance times are required, and personnel safety is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of agitators, in particular to a high temperature resistant dry friction permanent magnetic levitation agitator. Background technique

[0002] Nuclear power, petrochemical, pharmaceutical and other fields have very high requirements on the reliability and service life of agitator equipment working under high temperature, high pressure, strong corrosive, strong leakage medium and strong radioactive working conditions, but are affected by materials, structures, radioactivity and effects Due to the limitation of force and other conditions, domestic or imported agitators are used. Since the bearings cannot solve the bearing lubrication problem in high temperature environments, the service life of the agitators is extremely short and the purchase cost is extremely high. At the same time, it is extremely difficult to overhaul in radioactive, toxic and harmful environments, and the lives of maintenance personnel are...
