Problems solved by technology
[0003] However, since the screen is installed horizontally in the working area of the room temperature hole of the superconducting magnet, it is perpendicular to the flow direction of the slurry and spray water, so there are the following defects: (1) The working area of the screen is the smallest, and it is easy to block and affect the separation effect ; (2) The free fall of the pulp and spray water has a large drop, and its impact force will greatly damage the screen, and the screen is easily damaged; (3) The impact force of the free fall will easily cause the agglomerated particles slightly larger than the screen mesh to be affected by the impact force. Passes through the screen, reducing the separation effect

Embodiment Construction
[0014] The present invention will be further described in conjunction with accompanying drawing:
[0015] Such as figure 1 Shown is the state of the flow-conducting magnetic agglomeration and magnetic separation separation frame in the room temperature hole of the superconducting magnet. The separation frame dragged by the chain 9 into and out of the room temperature hole of the superconducting magnet has a slurry inlet 1, and a spray pipe 7 and more. Spray water 8 to the separation frame. A mineral guide plate 2 is provided at the pulp inlet 1. The mineral guide plate 2 has a pulp guide surface 3 and a magnetic agglomeration mineral guide surface 4. The pulp guide surface 3 is in contact with the horizontal plane. The included angle B of 5 is 8 degrees, and the included angle between the magnetic agglomerated mineral guide surface 4 and the horizontal plane 5 is 45 degrees.
[0016] A separation screen 6 is arranged in the separation frame and below the mineral guide plate 2...

The invention discloses a diversion type magnetic aggregation magnetic separation frame. The separation frame is provided with an ore pulp inlet, an ore guide plate is arranged at the ore pulp inlet, the ore guide plate is provided with an ore pulp guide surface and a magnetic aggregation mineral guide surface, the included angle between the ore pulp guide surface and the horizontal plane is 6-10degrees, and the included angle between the magnetic aggregation mineral guide surface and the horizontal plane is more than 0 degree and less than 90 degrees. The diversion type magnetic aggregationmagnetic separation frame disclosed by the invention can be used for effectively reducing the initial speed when the ore pulp enters into the separation frame, thus a magnetic mineral can be fully subjected to magnetic aggregation, and the magnetic mineral and a non-magnetic mineral can be thoroughly separated.
Description
technical field [0001] The invention relates to a magnetic separation device, in particular to a flow-guiding magnetic agglomeration magnetic separation frame. Background technique [0002] Chinese patent document CN101920223A discloses a superconducting magnetic separation device, which includes a solenoid superconducting magnet, and also includes a main driving wheel and a driven wheel, and an annular closed screen conveyor belt is wound on the main driving wheel and the driven wheel , the bearing surface of the screen-type conveyor belt is the screen in the separation frame, and a part of the screen-type conveyor belt passes through the room temperature hole of the superconducting magnet, and a part is located outside the superconducting magnet. This superconducting magnetic separation device utilizes the characteristics that the magnetic particles in the pulp are magnetized and agglomerated in the magnetic field to form particles larger than the mesh of the screen and mu...
