Abstract

The invention discloses a parallel separation chamber of super-conducting magnetic separator and a method of achieving uniform water distribution therewith. The separation chamber comprises a water inlet pipe, an outer sleeve, and a separation chamber located therebetween. A plurality of separation zones, of which the quantity is an even number, are uniformly distributed in the separation chamberin parallel, a high-gradient medium arranged in each separation zone; a water inlet pipe water channel is annularly arranged on the water inlet pipe at the corresponding position between each two separation zones; an outer sleeve water channel is arranged on the outer sleeve in an annular manner; one or more of the total area of the water distribution cross section of the water inlet pipe water channel, the total area of the water passing cross section of the high-gradient medium, and the total area of the water distribution cross section of the outer sleeve, which are corresponding to the separation zones, are smaller than the area of the cross section of the water inlet pipe or the area of the cross section of an outer water backflow channel of the outer sleeve, which is subjected to thesmaller number. The parallel separation chamber allows uniform water distribution, so that process precision and industrial production stability of the super-conducting magnetic separator system aregreatly improved, and continuous industrial production of the super-conducting magnetic separator is ensured.

Description

technical field [0001] The invention relates to an ore pulp magnetic separation equipment, in particular to a parallel separation chamber of a superconducting magnetic separator and a method for realizing uniform water distribution. Background technique [0002] The solenoid superconducting magnetic separator generally adopts the reciprocating series tank sorting structure. The magnet is placed horizontally. The axis of the magnet is parallel to the horizontal plane. The reciprocating series tank passes through the magnet and is divided into two working areas and three dummy units. (Magnetic balance area) One working area operates in the magnetic field while the other working area elutes outside the magnetic field. This structure was patented by the United Kingdom many years ago and has expired. Outotec and other foreign superconducting magnetic separator manufacturers and domestic equipment companies such as Jiangsu Jingkai and Shandong Huate all adopt this sorting structur...
