The specific embodiment
Embodiment one
The conveying electromagnetism self-unloading deironing system of present embodiment as shown in Figure 1, comprise the suspension walking mechanism that is horizontally through mineral aggregate conveyer belt 1 top, be hung on the electromagnetic separator 2 that hangs the walking mechanism below and be positioned near the mineral aggregate conveyer belt 1 switch board 3, be mounted with metal detector 4 at mineral aggregate conveyer belt 1 side and along the place ahead that throughput direction is positioned at electromagnetic separator 2.Metal detector 4 is non-contact type detectors, partly is made of probe and control circuit, and probe adopts inductance element.
As shown in Figure 2, hanging walking mechanism includes fixed guide 5, places the dolly 6 that is slidingly connected with it on the fixed guide 5.Electromagnetic separator 2 is hung in the lower edge of dolly 6, and the two ends of fixed guide 5 are provided with limit switch 7, and dolly 6 carries drive unit.
Contain the control field circuit of the high and low threshold voltage of output that can freely switch and superpose at switch board 3; One of output of control field circuit is connected by cable with the input of electromagnetic separator 2, two of its output is connected by cable with input that dolly 6 carries drive unit, one of its input is connected by cable with the output of metal detector, and two of its input is connected by cable with the output of limit switch 7.
When the conveying electromagnetism self-unloading deironing system of present embodiment is installed, electromagnetic separator 2 is installed in the middle part of conveyer belt, as shown in Figure 1, because this moment, mineral aggregate had pressure to the ironware foreign material, influence the smooth sucking-off of ferromagnetic sundries, the following increase that therefore is preferably in conveyer belt does not have magnetic carrying roller 8 for one group, when making conveyer belt run to herein to upper process, make material be in loose state, being beneficial to ferromagnetic sundries can be picked up smoothly.Metal detector 4 is installed in the place ahead along throughput direction, electromagnetic separator 2 positions, the distance of metal detector 4 and electromagnetic separator 2 generally is made as the speed of service of 5-10 times of conveyer belt, purpose is to guarantee to allow the electromagnet of electromagnetic separator 2 that enough excitation time is arranged after metal detector 4 is visited ironware and sent signal immediately.Usually the excitation of electromagnet is greatly about the 3-7 time of second, and this time will lack under the state that has weak excitation to keep.
When using the conveying electromagnetism self-unloading deironing system of present embodiment, when conveyer belt 1 brings into operation, connect by the conveyer belt 1 and the interlock switch of switch board 3, the control field circuit of switch board 3 brings into operation, and export the exciting current of low voltages for electromagnetic separator 2, make electromagnetic separator 2 be in weak magnetic duty, the mineral aggregate on the conveyer belt can not picked up because of magnetic attraction is less; Control field circuit simultaneously and send signal controlling dolly 6 and drive electromagnetic separators 2, run to conveyer belt top preposition await orders (preposition is controlled by limit switch 7 and control field circuit).
In case sneak into ironware in the material, the metal detector 4 in electromagnetic separator 2 the place aheads is when detecting ironware, issue a signal to the control field circuit immediately, the control field circuit is exported the electromagnet (this high threshold voltage be superimposed upon low voltage on) of the exciting current of high threshold voltage to electromagnetic separator 2 at once.When ironware arrives electromagnetic separator 2 lower positions, the magnetic field of electromagnetic separator 2 also just reaches the maximum of excitation, electromagnetic separator 2 is in strong magnetic duty this moment, and the ironware on the conveyer belt is picked up under the forceful electric power magneticaction, simultaneously a part of paramagnetism bigger mineral aggregate also picked up.
Ironware by electromagnet below constantly the utmost point after the short time (be set at 0.1-0.5 second), the control field circuit sends signal again, remove high threshold voltage exciting current, and the low voltage exciting current still keeps, this moment, electromagnetic separator 2 was in weak magnetic duty again, the weak magnetic mineral aggregate that is sucked out of part falls back one after another again to continuing to be transferred on the conveyer belt and advances to subsequent processing, and ironware is still inhaled on electromagnetic separator by the jail and can not drop that (this is because the electromagnet of same magnetic induction intensity with mineral aggregate, to the attraction that ironware produced, be to increase by the geometric progression of ironware and electromagnet surface distance, in case so after ironware is adsorbed on magnet surface, only needs a less magnetic field intensity just can be held firmly and can not drop).
After passing through the several seconds (setting value) again, this moment, mineral aggregate fell only substantially, 6 actions of control field circuit instruction dolly, and drive electromagnetic separator 2 moves to and unloads iron district (preposition is controlled by limit switch 7 and control field circuit).After the iron district was unloaded in arrival, the control field circuit sent signal and gives electromagnetic separator 2 outages, and the excitation of electromagnetic separator 2 stops.The ironware of suction on electromagnetic separator 2 fallen in the collection iron case 9 that unloads the iron district owing to the disappearance in magnetic field, finishes iron removal.Behind Preset Time (by cutting off the power supply to the time of unsnatching iron of control field circuit control) from electromagnetic separator 2, the control field circuit is controlled the weak excitation of electromagnetic separator 2 beginning again and is controlled the position that dolly 6 gets back to original conveyer belt top with electromagnetic separator 2 and await orders, and so finishes one-period.
In addition, leave in the process of conveyer belt with electromagnetic separator 2 at dolly 6, if metal detector 4 is found ironware again, the signal that sends according to metal detector, the control field circuit can send instruction immediately makes dolly 6 return the position of original conveyer belt top immediately, guarantees not leak the ironware on the conveyer belt.
Embodiment two
The conveying electromagnetism self-unloading deironing system and the embodiment one of present embodiment are basic identical, different is, as shown in Figure 3, hanging walking mechanism is vertically to pass the top of conveyer belt end along running direction of conveyor belt, electromagnetic separator 2 is positioned at the end of conveyer belt, carry this moment mineral aggregate to be in best loose state, can pick up the ironware foreign material in the mineral aggregate to greatest extent.
Practice by the applicant proves, conveying electromagnetism self-unloading deironing of the present utility model system, only use an electromagnetic separator can finish automatic suction and put the ironware that is mixed in the conveying mineral aggregate, thereby make more quick and convenient and the saving cost and the energy the automatic iron removing of conveyer belt; And because the transhipment mineral aggregate program that can not adsorb the weakly magnetic mineral material and avoid magnetic force deironing in the past to exist meaninglessly, thereby effectively reduce the waste of mineral aggregate.
The utility model can also have other embodiments, limits to substitute the limit switch restriction such as dolly run location in the foregoing description also running time of available setting; Dolly also can substitute with electric block etc.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
