Embodiment 1

[0016] Such as figure 1 As shown, the present invention comprises cylinder body 1, ore supply pipe 2, water supply pipe 3, concentrate pipe 4, overflow tank body 5 and excitation power supply 6, adopts stable magnetic field as working magnetic field in order to solve existing magnetic separator, and magnetic field The gradient is high, there are problems such as low concentrate grade, high height, complex structure, and high production cost. A magnetic field device 7 for generating an alternating magnetic field is provided on the outer wall of the lower part of the cylinder body 1. 6 phases are connected to generate a uniform alternating magnetic field that runs through the cylinder 1, and the magnetic field device 7 is installed on the cylindrical outer wall of the lower part of the cylinder 1. At the same time, in order to improve the recovery rate and separation efficiency of magnetic concentrate and reduce the loss of concentrate, some of the strong magnetic particles ente...

Embodiment 2

[0018] Such as figure 2 As shown, this embodiment includes a cylinder body 1, a magnetic field device, an ore supply pipe 2, a water supply pipe 3, a concentrate pipe 4, an overflow tank body 5 and an excitation power supply 6. In order to make the present invention applicable to occasions with a large amount of ore pulp , to provide a strong stirring shear force for sorting, to avoid the problem that the separation effect is not good only by the stirring shear force provided by tangential water supply. The difference between this embodiment and Embodiment 1 is: the cylinder body 1 A stirring device 9 is provided, which includes a stirring rod 91 with a stirring blade 911, the upper part of the stirring rod 91 is supported in the bearing seat 10, and the bearing seat 10 is installed on the support plate 20 on the upper part of the cylinder body 1, and is installed on the The upper and lower stirring blades 911 on the stirring rod 91 are misplaced to strengthen the separation ...

Abstract

The vertical impulse vibration magnetic-field magnetic separator indudes cylindrical body, mineral feeding pipe, water feeding pipe, concentrate pipe, overflow tank body and excitation power supply, and is characterized by that on the external wall of lower portion of cylindrical body a magnetic field device for producing alternating magnetic field is set, it is connected with excitatino power supply for producing uniofrm alternating magnetic field passing through the cylindrical body. Said inventino adopts the vertical structure capable of producing alternating magnetic field to make magnetic separation, so that it effectively raise grade of separated concentrate and its recovery rate.

Description

technical field [0001] The invention relates to a magnetic separator for ore dressing, in particular to a vertical pulse vibration magnetic field magnetic separator. Background technique [0002] In the existing weak magnetic separation equipment, the mechanical inclusion caused by magnetic agglomeration is the main reason for the low quality of strong magnetic concentrate products. Concentrate purification and separation equipment commonly used in strong magnetic mineral processing plants include drum-type weak magnetic separators, magnetic desliming tanks, magnetic concentrators and magnetic separation columns. Drum magnetic separators generally use permanent magnets as the magnetic system, the magnetic system of the desilting tank is tower-shaped, and the magnetic system of the magnetic concentrator is multi-circle layer dispersed. Get a certain dispersion, reduce non-magnetic mechanical inclusions, thereby improving the grade of concentrate. However, because the magnet...
