Description
Technical Field
The utility model belongs to the technical field of mineral processing equipment, and particularly relates to a water supply and pressure stabilization automatic control device for a magnetic separation column.
Background
With the development of industrial economy in China, the continuous promotion of infrastructure construction and urbanization, the pressure of energy and raw materials is higher and higher, the ore is easy to select, coarse-grained ore and high-grade ore are exhausted, and the energy-saving and efficient development of iron ore resources which are rich in reserves in China but low in grade becomes a key point and a hotspot of research in the field of mineral processing.
At present, most of the ferrous metals are in poor, fine and miscellaneous mines development, so that the sorting difficulty is high, and the conventional sorting magnetic separation equipment for ferrous metals faces a large challenge. In order to overcome the defects of the conventional magnetic separation equipment in the application of iron extraction and silicon reduction, magnetic separation equipment such as a magnetic dewatering tank, a magnetic gravity separator, a low-field-intensity pulsating magnetic separator, a pulse vibration magnetic field magnetic separation column, a composite magnetic field separator and the like are developed in succession by various manufacturers and research units at home and abroad.
The magnetic separation column is widely applied, and no matter the separation principle of the pulse and vibration magnetic field magnetic separation column which is successfully developed by Anshan iron and steel institute mineral separation teaching and research room, northeast university and the like is basically the same, the magnetic field in the spiral coil is utilized to enable magnetic minerals to be agglomerated and sink rapidly. Compared with similar magnetic gravity concentrating machines applied at home and abroad, the magnetic gravity concentrating machine is only innovated in magnetizing coil combination and magnetic field characteristics.
The ascending impulse force of the ascending water flow is a key factor of the magnetic separation column for separating medium and poor intergrowths in which magnetic minerals are magnetically mixed and monomer gangue in which non-magnetic minerals are mixed, the intensity of a magnetic field in the magnetic separation column can only change the downward moving speed of magnetic mineral particles in a mine award, but cannot enable the gangue intergrowths to escape and separate, and therefore the adjustment of the ascending water flow is the key factor of the separation quality of the magnetic separation column.
The following disadvantages arise in industrial applications: (1) and the sorting effect on the fine particle magnetite is not ideal. Because the magnetic field of the magnetic separation column is only 8 kA/m-16 kA/m, the magnetic field force on the fine particle magnetic minerals cannot effectively overcome the action of ascending water flow force, overflow tailings are prone to run black, and the recovery rate of the magnetic minerals is affected. (2) Water volume pressure cannot be quantified qualitatively. The magnetic separation column utilizes ascending water flow power to flush coarse-particle gangue into tailings, the ascending water flow speed is increased to overcome the sedimentation speed, and the increase of the water flow ascending speed causes the poor effect of fine-particle magnetic mineral separation; on the contrary, the coarse-grained gangue can move downwards to enter the concentrate because the settling velocity is greater than the ascending water flow velocity, thereby reducing the concentrate grade. (3) And the water consumption is large. When the magnetic separation column is used for separation operation, the velocity of ascending water flow must be larger than the sedimentation velocity of coarse-particle gangue, and the water consumption is larger due to the 'downstream-upstream' tailing discharge mode.
