Embodiment Construction
[0029] Such as figure 2 The magnetic fluid density sorting demonstration instrument shown is mainly composed of an electromagnet system, a magnetic fluid container 1, and a material particle transmission system. The electromagnet system is composed of a magnetic pole 7, an upper yoke 8, an iron core, a lower yoke 11, and a wire package 10. The coil system is fixedly installed in the instrument box 12, and the magnetic poles, the magnetic fluid container, and the transmission system are installed on the surface of the box body, and the design of a pair of magnetic poles is the most important, and the opening angle, shape, and size of the magnetic pole 7 will directly It is related to the performance of the sorting demonstrator. From figure 1 It can be seen that when the magnetic pole is long and the opening angle is small, the change of HH / d with x is small, that is to say, the change of a large distance in the x direction, while the change of HH / d will not be large , so tha...

The invention discloses a magnetism liquid density sorting demonstrator which relates to teaching instrument and the pole flare angle is an adjustable flare angle of 20-30 degree; the bottom middle of a container is of reversed V-shaped, the sloping bottom two sides in the container are respectively arranged with a long pipeline and a short pipeline, while the bottoms of the sloping bottom are communicated with a long pipeline feed inlet and a short pipeline feed inlet of the material grain transmitting system, wherein the long pipeline and the short pipeline are provided with tackles above the pipeline. The bottom of the sling on the tackles is fixed on the material suspending basket, which is arranged at the bottom of the pipeline and communicated with the material inlet of the pipeline side wall. A gutter is arranged on the side wall above the pipeline, and the gutter of the short pipeline is communicated with a mixing groove, the bottom of which is a movable motherboard. The gutter of the long pipeline is communicated with a long material transporting groove which is communicated with a short material transporting groove communicated with the material mixing groove. The invention can sort the material grains in different density mixed together, alao can demonstrate the mill run and the different non ferrous metal shiver sorting.
Description
1. Technical field: [0001] The patent of the present invention relates to a teaching experiment instrument, in particular to a magnetic fluid physics experiment instrument. 2. Background technology: [0002] Magnetic fluid is a kind of paramagnetic liquid material, and its apparent density in a magnetic field will vary according to the strength of the magnetic field and its magnetic field. For the strength of the magnetic field, the apparent density of the magnetic fluid is large where the magnetic field gradient is large, and vice versa, the apparent density of the magnetic fluid is small where the magnetic field gradient is small. The research and application of magnetic fluid has developed rapidly. At present, some countries have developed a magnetic fluid separator, which has been applied in industry. They are generally called ferromagnetic liquid static separator. It is mainly used in ore beneficiation, and the separation of non-ferrous metal blocks after crushing wast...
