Abstract

The utility model discloses an electromagnetic mineral separating machine for teaching, which utilizes the principle of electric magnets to automatically separate the particles of ferromagnetic substances from the particles of non-ferromagnetic substances. When the utility model works, an electric magnet doesn't move, and a separating rolling barrel is driven by a miniature motor to rotate. When mixtures pass through the rolling barrel, under the action of the electric magnet, the particles of ferromagnetic substances are adsorbed to make motion on the surface of the rolling drum and automatically fall down when moving to the nonmagnetic area at the back part of the rolling barrel, and then the particles of non-ferromagnetic substances are thrown out along the tangential direction of the rolling drum to achieve the automatic separation.

Description

Electromagnetic concentrating machine

This usefulness is novel to relate to a kind of instruments used for education

At present, still do not have desirable teaching aid in the Experiments of Electromagnetism teaching, experiment effect is not obvious, does not have the effect of proof theory knowledge.

The purpose of this utility model be according in full-time, the requirement of primary school nature subject textbook.Provide a kind of simple in structure, principle is clear, have dynamic sense, visual in image, lightly durable, demonstration is convenient, can edify student thought, excites learning interest, the good teaching aid of effectively improving the quality of teaching.

For finishing above-mentioned task, solution of the present utility model is to utilize the electromagnet principle, and ferromagnetic material is separated with the nonferromagnetic corpuscle.Its architectural feature is that a separation barrel is set on frame, be built-in with wood spool at cylinder, electromagnet base is housed on the wood spool, an electromagnetism winding is housed on the electromagnet base, and the electromagnetism winding is made up of 3-7 group coil, every adjacent two coil magnetic pole different names, form closed magnetic field, be shaped on wiring hole on the wood spool, wood spool is fixed on the metal shaft, and the metal shaft two ends are fixedly mounted on the frame.Miniature 3V-9V dc motor is housed on the frame of the lower-left of separation barrel side, on the support between motor drive shaft and the cylinder intermediary wheel is housed, intermediary wheel utilizes the pulling force of spring to reconcile the frictional force of motor drive shaft and separation barrel.The downside that is positioned at separation barrel is equipped with two separatory funnels, and speed regulator, power pack and switch are housed on the base of frame, is provided with receiving hopper in the base, and hopper is equipped with in the top of frame, is equipped with valve on the hopper.

The utility model modern design, rational in infrastructure, production technology is simple, and principle of specification is clear, can excite student's aspiration to knowledge.

Be described further below in conjunction with accompanying drawing
