Abstract

The invention discloses a superconducting magnetic separator parallel separation mechanism capable of achieving uniform water distribution. The superconducting magnetic separator parallel separation mechanism comprises a water inlet pipe, a secondary outer sleeve and a separation cavity arranged between the water inlet pipe and the secondary outer sleeve; n (even number) parallel separation areasare uniformly distributed in the separation cavity, and a high gradient medium is arranged in each separation area; separation cavity water distribution hole channels are annularly arranged on the water inlet pipe at the corresponding middle position of each two separation areas; a water return hole channel is annularly arranged on the secondary outer sleeve, and an outer sleeve water return pipeline is formed by an annular gap between the secondary outer sleeve and the outer sleeve; the overall area of cross sections of the n separation cavity water distribution hole channel or the overall area of the water cross sections of the n high gradient mediums is controlled to be less than 80% of the cross section area of the water inlet pipe, or the cross section area of the outer sleeve water return pipeline is less than 50% of the cross section area of the water inlet pipe. The superconducting magnetic separator parallel separation mechanism provided by the invention is uniform in water distribution, can greatly improve the processing accuracy and industrial production stability of the superconducting magnetic separation system, and ensures the continuous industrial production of the superconducting magnetic separator.

Description

technical field [0001] The invention relates to a pulp magnetic separation equipment, in particular to a superconducting magnetic separator parallel separation mechanism capable of 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 zone) One working zone operates within the magnetic field while the other working zone 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 structure. It is ...
