The motor type magnetic air separator may be used as the precursor set for oxygen making machine and nitrogen making machine, as the oxygen enriching machine for replenishing oxygen to the vehicle in plateau area, as the oxygen supplier for persons needing oxygen supply, as the oxygen supplier for food packing or inflating tyre. The present invention has simple and integrated structure, portable, low making and running cost.

Description

A kind of motor type magnetic air separator

Technical field

The present invention relates to a kind of deaerator, particularly a kind of motor type magnetic air separator belongs to air and separates from technical field.

Background technology

As everyone knows, airborne Main Ingredients and Appearance is exactly to account for the nitrogen of volume 78% and 21% oxygen.Air separation just is meant separating of oxygen and nitrogen in general.Current, utilize magnetic material, the technology of carrying out air separation according to the difference of the magnetic susceptibility of oxygen in the air and nitrogen has become a kind of new air separating method, as: Chinese patent ZL97205039.6 " a kind of magnetic oxygenerator ", Chinese patent ZL94237972.1 " magnetic oxygen separator ", Chinese patent ZL92234219.5 " barrel field shunting permanent magnetism automatic aerator " etc., but said structure all is to aim at system oxygen and designing, act on single, also need be equipped with dynamic power machine structures such as motor, complex structure, cost is higher, and inconvenience is promoted! Wherein " a kind of magnetic oxygenerator ", " magnetic oxygen separator " all adopts linkage, noise is big, " barrel field shunting permanent magnetism automatic aerator " though adopted rotary structure, structure is still complicated, can not miniaturization, more inconvenient make portable!

Summary of the invention

The technical problem to be solved in the present invention provides a kind of motor type magnetic air separator, it is made up of motor, collection oxygen cover, cylinder, the axle of motor links to each other with cylinder, also process or be equipped with axial flow blower formula blade in it, the front of cylinder outer end is processed with the agitator type flight, install the back or the processing receded disk impeller also entangles with collection oxygen cover, is fixed on the body of motor with bolt again.Motor and casing adopt conventional standard model and power, and motor shaft is processed into hollow shaft, 1 to 3 group of axial flow blower formula blade of processing or mechanical connection routine in it.Cylinder is processed into cylindric, and the front of outer end is processed with 1 to 3 agitator type flight, and the back mechanical connection is installed or directly made and is processed into receded disk impeller, and directly manufactures one with the axle of motor or mechanical connection is fixed.Collection oxygen cover is made telescopic, some permanent-magnetic clamps that permanent-magnet material is made of applying mechanically are installed in it as requested, be good generally with the 5-10 cover, at one end be processed with the groove that receded disk impeller work is installed, the other end is processed into horn-like air inlet, circumference is processed the fixing bolt hole of several and motor body, is good with 4-10 generally, is fixed on the body with bolt again.Like this, when motor type magnetic air separator of the present invention is worked, motor gets electric rotation and makes surrounding air axial flow blower formula blade and 1 to 3 agitator type flight in hollow shaft, the negative pressure suction force that produces when receded disk impeller etc. together rotate is inhaled into from the horn-like air inlet of collection oxygen cover, because the difference of the magnetic susceptibility of oxygen and nitrogen in the air, the nitrogen that magnetic susceptibility is low is directly discharged in hollow shaft, and some permanent-magnetic clamps absorption that the high oxygen of magnetic susceptibility is made by permanent-magnet material and discharge from the hollow shaft outside at 1 negative pressure suction force that produces during to the stirring of 3 agitator type flights and receded disk impeller rotation, like this, the place can obtain nitrogen in the hollow shaft nitrogen interface, the oxygen interface can obtain oxygen in the hollow shaft outside, thereby reaches the purpose of air separation.

This motor type magnetic air separator of the present invention can be used as the front device of various oxygenerators, nitrogen making machine, as: molecular sieve air separation machine, film air separation machine etc.Can also be as oxygen enricher, as: the highlands is combustion powered for the vehicle motor oxygenating improves, and improves the oxygen content of breath for the staff; As aerating machine is the personnel's oxygenating that needs oxygenating; As nitrogen charger is to need the packaging for foodstuff of nitrogen to fill nitrogen, provides the inflated with nitrogen source for needs fill the nitrogen tire; Or the like.

The good effect that the present invention is useful is: simple in structure, have only several parts, the structure of motor and device one could make device miniaturization, conveniently makes portable! And adopting part and conventional production technology, manufacturing cost and operation are all lower.Therefore, the present invention's technology of utilizing magnetic material to carry out air separation at the difference of the magnetic susceptibility of oxygen in the air and nitrogen has played positive popularizing action.
