Permanent magnet coupling sealing motor stirring device

Abstract

The invention discloses a permanent magnet coupling sealing motor stirring device. The permanent magnet coupling sealing motor stirring device comprises a stirring shaft, a cavity body and an inner rotor, wherein the stirring shaft is positioned in the cavity body; the lower end of the stirring shaft is provided with a stirrer, and the upper end of the stirring shaft is connected with the inner rotor through a coupler; the periphery of the inner rotor is provided with a permanent magnet, the upper end of the inner rotor is sleeved on an upper bearing, the lower end of the inner rotor is sleeved on a lower bearing, and an isolation hood is arranged outside the permanent magnet; a coil is arranged outside the isolation hood, the coil is connected with a power line, and a positioning sleeve is arranged outside the coil. The permanent magnet coupling sealing motor stirring device disclosed by the invention has the advantages that the design is reasonable, the practicability is good, the coil and the inner rotor can realize full isolation through the isolation hood, a sealing cavity body and the exterior are fully isolated, the permanent magnet coupling sealing motor stirring device can realize well mixing and stirring, a condition that a chemical article leaks to cause serious damage is prevented, and the laboratory safety is strengthened.

Description

technical field [0001] The invention relates to a mixing and stirring device for mixing and stirring, in particular to a permanent magnetic coupling sealed motor stirring device. Background technique [0002] For the mixing and stirring of chemical experiment vessels, especially those that are in direct contact with the operator's body, the current existing mixing and stirring methods have poor sealing performance, and there is no isolation device in the stirring container, and the inner rotor and the coil are connected. , the sealing of the cavity cannot be achieved, which can easily cause chemical leakage and cause serious harm. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a permanent magnetic coupling sealed motor stirring device. [0004] In order to achieve the above object, the technical solution taken by the present invention to solve the technical problems is: [0005] A permanent magnetic coupling sealed ...
