Description
Technical field
The utility model relates to the special-purpose demagnetizer of ore-dressing practice, is specifically related to be applicable to the special-purpose demagnetizer of vanadium titano-magnetite ore dressing operation, belongs to metal metallurgy smelting technique of preparing field.
Background technology
In the iron ore dressing process,, before second section mill choosing, need take off magnetic to ore pulp particularly in the stage grading flow process.Because each department ore different in kind, used demagnetizer technical parameter is not quite similar.For example Panxi Diqu vanadium titano-magnetite ore has characteristics such as the big and remanent magnetism height of coercive force, need could use with there being the higher demagnetizer that takes off magnetic property that ore pulp is taken off magnetic, otherwise ore pulp produces the magnetic coagulation phenomenon because of remanent magnetism is arranged, can not satisfy the requirement of rough concentrate sieving technology, have a strong impact on grinding efficiency; Cause the production cost height, make the hypomere operation can not ordinary production simultaneously.The existing demagnetizer that is used for manufacturers such as Anshan, Shenyang, Shoudu Iron and Steel Co, Ma'an Mountain, be clearly not applicable for the magnetic that takes off of Panxi Diqu vanadium titano-magnetite ore, after using, find to exist the problem that result of use is relatively poor even can not take off magnetic, it is serious heating also to occur behind the operation some months, parameter instability, easy defective such as aging.
The content of utility model
Have the big and high characteristic of remanent magnetism of coercive force at vanadium titano-magnetite, the purpose of this utility model provides a kind of remanent magnetism of vanadium titano-magnetite can not only being taken off fully totally, and parameter stability, the efficient vanadium titanium demagnetizer of long service life.
The purpose of this utility model is achieved in that vanadium titanium demagnetizer, by taking off magnetic coil and trigger two parts are formed; Take off magnetic coil and adopt dual-fiberglass wrapped flat copper wire to turn to the coil of at least three parallel connections, the two ends of coil are connected to by the control discharging thyristor of trigger and the two ends of capacitor.
The utility model is formed antiresonant circuit according to the basic principle of LC vibration with electric capacity and demagnetizer coil, makes it produce damped oscillation, produces high frequency and take off magnetic magnetic field in the demagnetizer coil, make material when flowing through coil by degaussing.
Compared to existing technology, the utlity model has following advantage:
1, the trigger of this demagnetizer partly adopts integrated circuit, and it is whole to increase frequency adjustable, its integrated level and reliability height;
2, the magnetic coil that takes off of this demagnetizer adopts three coils from parallel connection of coils of dual-fiberglass wrapped flat copper wire coiling to use; It is effective to have the magnetic of taking off, characteristics such as parameter stability, long service life.
3, this demagnetizer to take off magnetic field powerful, transformer can turn to actual the set up gear of fourth gear (750V 800V 850V900V) according to the scene.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 2 is the circuit theory diagrams of the utility model trigger.
Fig. 3 is trigger control section circuit theory diagrams.
Embodiment
As shown in Figure 1, the efficient vanadium titanium of the utility model demagnetizer is by taking off magnetic coil 1 and trigger 2 two parts are formed; Take off the coil that magnetic coil 1 adopts three parallel connections of dual-fiberglass wrapped flat copper wire 4.6*12.5 coiling, the two ends of coil are connected to the control discharging thyristor of trigger and the two ends of capacitor.Taking off magnetic coil 1 is sleeved on outside the wear-resisting ore pulp pipe 3.When wear-resisting ore pulp pipe 3 fed the v-ti magnetite ore pulp, shown in the figure arrow, the high frequency that produces in the demagnetizer coil 1 took off magnetic magnetic field, makes magnetic ore particle wherein be subjected to taking off repeatedly magnetic, promptly loses remanent magnetism and reaches the purpose of taking off magnetic.
Referring to Fig. 2, trigger partly adopts integrated circuit, and control system is to remove control charging controllable silicon SCR 1 and discharging thyristor SCR2 by pulse signal circuits for triggering-driving loop.When the SCR1 conducting, the electric current after rectification is to capacitor C 2 chargings, and this moment, SCR2 closed; SCR1 closes and the SCR2 conducting within a certain period of time, and form antiresonant circuit by C2 and demagnetizer coil MCL this moment.
Fig. 3 is the circuit theory diagrams of circuits for triggering-driving loop one execution mode.
Embodiment 2: take off the coil that magnetic coil also can adopt 5 or 7 parallel connections.
