Description
Technical field
The present invention relates to preparation equipment technical field, more particularly to a kind of magnet exciting coil of vertical ring high-gradient magnetic separator.
Background technology
At present, in sorting mineral process equipment, wet type vertical ring high-gradient magnetic separator is widely used, mainly in
Based on small-sized.Its type of cooling is mainly internal water cooling and oil cooling, and because 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, is otherwise easily formed and blocked, therefore in use by a definite limitation.Forced oil cooling
But vertical ring high-gradient magnetic separator uses closure, and coil is immersed in transformer oil, and horizontal oil is left between each layer line disk
Ebb interval, is cooled down using outer circulation to coil, middle-size and small-size vertical ring coil can be applicable, effect is preferable.With mineral plus
Work cost efficiency is constantly lifted, and is improved unit treating capacity, is increasingly paid close attention to by ore dressing industry, large-scale vertical ring high-gradient magnetic separator
Step into market.At present, the sorting swivel diameter of forced-oil-cooled vertical ring high-gradient has reached more than 5 meters, 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, its deficiency
It is：Although leaving horizontally disposed oil duct between each drum, because runner is longer, gap is small, and oil flow rate degree is slack-off, and gas is difficult
Discharge, heat exchange is slow after oil temperature rise, and internal-external temperature difference is big, and radiating effect is under some influence, to sorting the lifting in magnetic field and steady
It is qualitative to bring adverse effect.
The content of the invention
In view of this, the technical problems to be solved by the invention are：A kind of vertical ring high-gradient magnetic separator magnet exciting coil is provided,
The magnet exciting coil can accelerate oil flow rate degree, improve radiating effect, meet large-scale vertical ring high-gradient magnetic separator needs.
In order to solve the above technical problems, the technical scheme is that：Vertical ring high-gradient magnetic separator magnet exciting coil, including：

The excitation drum between be positioned apart from layer insulation filler strip, the layer insulation filler strip makes between the excitation drum
Interlayer cooling passage is formed, the excitation drum is obliquely installed, and the periphery of the excitation drum is low, inner circumferential is high.
Further improved the following is many places of the vertical ring high-gradient magnetic separator magnet exciting coil to the present invention：
Wherein, be provided between the inwall of the inner circumferential of the excitation drum and the coil case inner chamber be vertically arranged and
Longitudinal cooling passage of up/down perforation is formed between spaced longitudinal direction insulation filler strip, the longitudinal direction insulation filler strip, it is described
Longitudinal cooling passage is connected with the interlayer cooling liquid passage.
Wherein, it is described longitudinal direction insulation filler strip and the coil case inner chamber inwall between be additionally provided with lateral arrangement and
Spaced lateral isolation filler strip.
Wherein, lower support frame, the excitation drum of top are provided with below the excitation drum of the bottom
Top be provided with support frame.
Wherein, the lower support frame, the upper support frame were all provided with oily breach.
Wherein, it is connected with take-up device between the lower support frame and the upper support frame.
Wherein, the endoporus of the coil case is in dolioform.
Wherein, the oil inlet and oil-out of the coil case are located at its two ends, the oil inlet, the oil-out respectively
Two are respectively arranged with, two oil inlets, two oil-outs are respectively by being arranged in the coil case inner chamber
Flow distribution plate is separated.
Employ after above-mentioned technical proposal, beneficial effects of the present invention are as follows：
1. because each excitation drum in coil case inner chamber is obliquely installed, and the periphery of excitation drum is low, inner circumferential is high,
So that interlayer cooling liquid passage is correspondingly obliquely installed, making the cooling oil after heat absorption, edge is inclined naturally under the promotion of oil pump
Oblique interlayer cooling liquid passage rises, and compared to the horizontally disposed interlayer cooling liquid passage of prior art, inclined interlayer is cold
But liquid passage accelerates the speed that deep fat rises in the passage between each excitation drum, is conducive to oil to circulate and gas discharge, interior
The outer temperature difference is small, and radiating efficiency is high, and especially for large-scale magnet exciting coil, radiating effect is obviously improved.
2. because the endoporus of coil case is in dolioform so that coil in coil case endoporus periphery excitation drum four
Week correspondingly makes to form nature tension between each excitation wire during coiling excitation wire, fits tighter, prevented excitation wire in dolioform
Shake friction problem is produced during energization, is conducive to improving the stability and service life of magnet exciting coil.
3. because coil case two ends are respectively arranged with two oil inlets, two oil-outs, two oil inlets, two it is fuel-displaced
Separated respectively by flow distribution plate between mouthful, the inner chamber of coil case is divided into two relatively independent oil pockets, its flow equilibrium is adopted
With valve regulated, heat is taken away soon, good heat dissipation effect, the stability of a system is good.
