Problems solved by technology

Since the rotation of the cylinder will generate centrifugal force, it will offset part of the magnetic force generated by the magnet, which will reduce the adsorption capacity of the magnet to magnetic materials and affect the magnetic separation effect.

Embodiment Construction

[0015] Embodiments of the invention. like figure 1 As shown, the cylinder 1 is made, the cylinder 1 is installed vertically, the magnet 2 is installed on the cylinder 1, the stirring blade 4 is installed in the cylinder 1, and the stirring blade 4 is connected to a transmission mechanism or a reducer.

[0016] The magnets 2 are arranged and installed on the cylinder body 1, and a protective layer 5 is arranged on the surface of the magnets 2 to improve the service life of the magnets 2. Moreover, the magnet 2 is usually assembled on the cylinder 1, there will be gaps between the magnets 2, and the magnetic material is adsorbed in the gap and it is difficult to clean. The protective layer 5 can protect the magnet 2 while avoiding the influence of the gap on the magnetic separation effect. Protective layer 5 can be antirust paint or thin stainless steel plate.

[0017] A discharge pipe 3 is installed at the lower part of the cylinder body 1, and the discharge pipe 3 is respect...

Abstract

The invention discloses a vertical magnetic separation method and a vertical magnetic separation device. The vertical magnetic separation method is characterized in that materials are placed into a vertical barrel (1) after being crushed into slurry, and then are stirred and rotated through stirring blades (4), so that the magnetic materials are attracted by magnets (2) on the barrel (1), and the magnetic materials in the materials are separated. The magnetic separation barrel is vertically mounted and provided with the magnets, the materials are close to the magnets of the barrel under drive of the stirring blades and are attracted by the magnets when in magnetic separation, and as centrifugal force of the barrel is identical with the magnetic force in direction, rotation of the materials cannot reduce magnetic attracting effects of the magnets, and magnetic separation effects are enhanced. As applicants test, the vertical magnetic separation device can reduce the iron content to be lower than 0.2% and is higher in the magnetic separation effects than existing superconductive magnetic separation equipment. Besides, the vertical magnetic separation device is simple, low in cost and suitable for small-scale production.

Description

technical field [0001] The invention relates to a vertical magnetic separation method and device, belonging to the technical field of magnetic separation. Background technique [0002] In the prior art, the magnetic separation equipment usually has a columnar magnet installed in a horizontal cylinder, the cylinder rotates, and the material is adsorbed on the magnet after contacting the magnet. Since the rotation of the cylinder will generate centrifugal force, it will offset part of the magnetic force generated by the magnet, which will reduce the adsorption capacity of the magnet to the magnetic material and affect the magnetic separation effect. Contents of the invention [0003] The object of the present invention is to provide a vertical magnetic separation method and device. Eliminate the influence of centrifugal force generated by rotating and stirring materials on magnetic separation, and improve the effect of magnetic separation. [0004] Technical scheme of the ...
