Technical field
The present invention relates to preparation equipment technical field more particularly to a kind of magnet exciting coils of vertical ring high-gradient magnetic separator.
Background technique
Currently, wet type vertical ring high-gradient magnetic separator is widely used, mainly in sorting mineral process equipment
Based on small-sized.Its type of cooling is mainly that internal water cooling and oil are cold, and since internal water cooling is using water flowing inside hollow electromagnetic line, runner is cut
Face is small, flow is small, higher to water quality requirement, otherwise blocking easy to form, therefore is subject to certain restrictions in use.Forced oil cooling
But vertical ring high-gradient magnetic separator uses closure, and coil is immersed in transformer oil, and there are horizontal oil between each layer line disk
Ebb interval cools down coil using outer circulation, can be applicable in middle-size and small-size vertical ring coil, effect is preferable.With mineral plus
Work cost efficiency is constantly promoted, and improves single machine treating capacity, the increasingly concern by ore dressing industry, large-scale vertical ring high-gradient magnetic separator
Step into market.Currently, the sorting swivel diameter of forced-oil-cooled vertical ring high-gradient has reached 5 meters or more, due to
The cross section of the magnet exciting coil of large-scale vertical ring high-gradient magnetic separator is larger, and each excitation drum of coil is using horizontally disposed, deficiency
Be: although there are horizontally disposed oil ducts between each drum, since runner is longer, gap is small, and oil stream slows, and gas is not easy
Discharge, heat exchange is slow after oil temperature increases, and internal-external temperature difference is big, and heat dissipation effect is affected, to the promotion for sorting magnetic field and surely
It is qualitative to bring adverse effect.
Summary of the invention
In view of this, the technical problems to be solved by the present invention are: provide a kind of vertical ring high-gradient magnetic separator magnet exciting coil,

Wherein, tension device is connected between the lower support frame and the upper support frame.
Wherein, the inner hole of the coil case is in dolioform.
Wherein, the oil inlet of the coil case and oil outlet are located at its both ends, the oil inlet, the oil outlet
There are two being respectively set, two oil inlets, two oil outlets are respectively by being set in the coil case inner cavity
Flow distribution plate separates.
After above-mentioned technical proposal, beneficial effects of the present invention are as follows:
1. since each excitation drum in coil case inner cavity is obliquely installed, and the periphery of excitation drum is low, inner circumferential is high,
So that interlayer cooling liquid channel is correspondingly obliquely installed, the cooling oil after making heat absorption under the promotion of oil pump incline naturally by edge
Oblique interlayer cooling liquid channel rises, horizontally disposed interlayer cooling liquid channel compared with the prior art, and inclined interlayer is cold
But liquid channel accelerates the speed that hot oil rises in the channel between each excitation drum, is conducive to oil circulation and gas discharge, interior
The outer temperature difference is small, and radiating efficiency is high, and especially for large-scale magnet exciting coil, heat dissipation effect is obviously improved.
2. since the inner hole of coil case is in dolioform so that coiling in coil case inner hole periphery excitation drum four
Week correspondingly in dolioform, makes to form nature tension between each excitation wire when coiling excitation wire, is bonded tighter, has prevented excitation wire
Shake friction problem is generated when energization, is conducive to the stability and service life that improve magnet exciting coil.
3. since coil case both ends are respectively set there are two oil inlet, two oil outlets, two oil inlets, two it is fuel-displaced
It is separated respectively by flow distribution plate between mouthful, so that the inner cavity of coil case is divided into two relatively independent oil pockets, flow equilibrium is adopted
With valve regulated, it is fast to take away heat, good heat dissipation effect, and system stability is good.
