Problems solved by technology
The concentration of the magnetic suspension liquid is required to be stable during the wet powder flaw detection process. If the magnetic suspension liquid precipitates during the spraying process and the concentration of the magnetic suspension liquid is too low, the magnetization effect will be poor and the accuracy of the magnetic particle flaw detection will be affected.
[0003] At present, in order to avoid the precipitation of the magnetic suspension during the spraying process of the magnetic particle flaw detection, it is necessary to continuously stir the magnetic suspension. The existing magnetic suspension is stirred by pneumatic air blowing, but this stirring method is prone to eddy currents during the stirring process Phenomenon, affect the mixing effect
In addition, the existing magnetic suspension uses a square flat-bottom container for stirring, and the magnetic powder is easy to form magnetic powder precipitation at the bottom of the container. At the same time, there is a stirring blind area at the corner of the magnetic powder container, which leads to waste of magnetic powder and increases production costs.

Embodiment
[0021] Such as figure 1 As shown, a magnetic suspension automatic stirring device, the stirring device includes a magnetic suspension container 1, a stirrer and a driver, the magnetic suspension container 1 is filled with a storage space for the magnetic suspension in the shape of a circular arc pot bottom, and the stirrer Set the magnetic suspension container 1, and connect the driver to the stirrer. Among them, the magnetic suspension container 1 includes a container shell and a container liner. The container shell is square, and the container liner is placed in the container shell. The 90° dead angle effectively prevents the magnetic powder from gathering at the 90° dead angle, which further improves the utilization rate of the magnetic powder and prevents waste.
[0022] The agitator is a propeller, and the propeller includes a paddle shaft 2 and a blade 3, the blade 3 is arranged at one end of the paddle shaft 2, the paddle shaft 2 is vertically arranged in the magnetic ...

The invention relates to an automatic stirring device for a magnetic suspension. The stirring device comprises a magnetic suspension container (1), a stirrer, a driver and a controller, the bottom of an accommodating space for storing the magnetic suspension in the magnetic suspension container (1) has an arc boiler bottom-shaped shape, the stirrer is arranged in the magnetic suspension container (1), and the driver is respectively connected with the stirrer and the controller; and the controller sends a starting signal to the driver, and the driver drives the stirrer to move in the magnetic suspension container (1) in order to stir the magnetic suspension solution. Compared with stirring devices in the prior art, the automatic stirring device in the invention has the advantages of realization of uniform stirring of the magnetic suspension, precipitation prevention, and reduction of the waste of magnetic powder.
Description
technical field [0001] The invention relates to a stirring device, in particular to an automatic stirring device for magnetic suspension. Background technique [0002] Magnetic particle testing can be divided into dry powder method and wet powder method according to the preparation of magnetic powder used in flaw detection. The wet powder method is to use the magnetic suspension mixed with magnetic powder and dispersant in a certain proportion, and spray it on the surface of the magnetized workpiece to detect the defects of the workpiece. The wet powder method requires the concentration of the magnetic suspension to be stable. If the concentration of the magnetic suspension is too low due to the precipitation of the magnetic suspension during the spraying process, the magnetization effect will be poor, which will affect the accuracy of the magnetic particle flaw detection. [0003] At present, in order to avoid the precipitation of the magnetic suspension during the sprayin...
