Abstract

The utility model relates to an automatic removing device for ferromagnetism matters. Based on the existing non-power cylinder type magnetic separator, an impeller is additionally arranged below the feeding port of a housing, and a transmission mechanism is connected between the impeller and a roller; materials fall firstly onto the impeller which is driven to rotate, then the materials fall onto the roller from the impeller, and under the action of the impeller and the transmission mechanism, the impeller rotates along with the impeller in the same direction to achieve the magnetic separation and exhaustion towards ferromagnetism impurities. The utility model solves the defect that the iron removal effect is reduced because of rapid or inhomogeneous feeding, and the efficiency of magnetic separation and impurity removal is obviously enhanced.

Description

Automatically separate magnetic separator de-ironing

The utility model relates to a kind of separator, specifically a kind of equipment that separates magnetisable material from material.

In grain processing, in the industries such as edible vegetable oil processing, wine brewing, feed, need clear up raw material, commonly used to de-iron equipment, the ferromagnetic metal impurity that will mix exactly in material screens, the one, prevent that it from flowing into next procedure and causing the damage of follow-up equipment, the 2nd, institute's converted products has certain limitation to iron-holder.The used automatic de-iron equipment of this class industry has motor-driven cylinder magnetic separator and unpowered stream cartridge type magnetic separator at present.Cylinder is that the axis horizontal that a non-magnet material is made is placed, is installed in the body, the magnetic separation roller of fan-shaped resident core is equipped with in its inside, fan-shaped magnetic core is static with respect to body, and cylinder can rotate around its axis, when the material that is flow to by the machine charging aperture falls into the discharging opening process along cylinder surface, the ferromagnetic metal impurity of sneaking in the material is positioned at the fan-shaped magnetic core magnetic field suction in the cylinder and is adsorbed in outer surface of cylinder, thereby rotate with cylinder, when rotating to when not having magnetic core regional, impurity breaks away from cylinder surface and falls into impurity outlet.The motor-driven cylinder rotates with certain speed by motor, reductor head roll exactly, and this magnetic separator needs consumes energy, and maintenance is complicated.Unpowered drum-type is to impact a plurality of rectangle impact bars head rolls that are fixed in cylinder surface by material to rotate, what of material are this magnetic separator cylinder velocity of rotation depend on, when materials flow is big, drum rotation speed is accelerated, cylinder surface impact bars outer rim forms a face of cylinder barrier, can't contact cylinder surface greater than the ferromagnetic metal impurity of material particles and just fall into discharging opening, thereby not have the magnetic separation effect.

The purpose of this utility model is the shortcoming at above-mentioned prior art, and a kind of not consumes energy is provided, and maintenance is simple, the de-iron equipment of automatic iron removing dependable performance.

The utility model is achieved in that at the casing top and has charging aperture, be connected with fan-shaped magnetic core and cylinder by the trunnion axis support in the casing, there is impurity to collect box in the casing bottom, and have a discharging opening, be connected with impeller by the axle support in the casing below charging aperture, have transmission mechanism to join between impeller and the cylinder.Material falls from charging aperture, at first drops on the impeller, and relies on the rotation of self gravitation drives impeller, then by falling to cylinder on the impeller.Cylinder rotates in the same way with impeller under transmission mechanism drives, and relies on fan-shaped magnetic core to attract and long-pending row's ferromagnetism impurity.Because material is to fall in two steps, has overcome the too urgent or irregular drawback of blanking, makes material and impurity all contact cylinder surface comparatively equably, and the magnetic separation impurity-eliminating effect is obviously improved.

Below in conjunction with accompanying drawing the utility model is further described.
