Independent high-speed asynchronous COM, hardware watchdog (WDT), has programming, debugging conveniently, low in energy consumption, disposal ability
By force, the advantages of peripheral module is more, suitable for this detection device.
In another embodiment, control element 2 can also be controlling switch, in the drive circuit of controlling switch and conveyer belt
Contact-making switch be linked switch.Detected when metal detection with inductance approach switch on conveyer belt there are during metallics,
Control signal can be sent, controlling switch is disconnected the contact-making switch in the drive circuit of conveyer belt, so that conveyer belt is shut down.
DC power supply 3 can be accumulator cell assembly or alterating and direct current pressure converter, can be by the alternating current of 220V
The direct current of 24V is converted to, is powered for metal detection with inductance approach switch.
It is different in view of the width of conveyer belt, for wider conveyer belt, a metal detection inductance approach switch
The width range of conveyer belt can not be covered, therefore, which can set multiple metal detections to be approached with inductance type
Switch 1.As shown in Fig. 2, multiple metal detections are in parallel with inductance approach switch 1.It is more when control element 2 is microprocessor
The output terminal of a metal detection inductance approach switch is connected with the input pin of microprocessor.When control element 2 is control
During system switch, each metal detection is connected a controlling switch with inductance approach switch, i.e., each metal detection inductance
The output terminal of formula close to switch is respectively connected with a controlling switch.
Metal detection device provided in this embodiment, it is small, it may be mounted in the space of relatively narrower;To work-yard
Electromagnetic environment requirements are low, and application prospect is extensive;The ability of metal detection inductance type close to inductive switching metal material is moderate, right
It is not necessarily to remove metallics in some biscuit metals or iron wire etc., will not makes a response, shut down cleaning, shorten at iron removaling
The time is managed, substantially increases the efficiency of Crushing equipment;And for the larger weak ferromagnetism metallics of volume, then it can sense
And stop the operation of conveyer belt, staff is cleared up metallics, reduce leakage and pick phenomenon.

When switch detects metallics, control element disconnects the drive circuit of conveyer belt, stops conveyer belt, to facilitate staff
Remove ferromagnetic material.
Metal detection inductance approach switch can use FRT210E120NT overlength distances to approach switch, this approaches and opens
Closing has that induction area is big, distance of reaction is remote, and reliable in action, performance are stablized, and frequency response is fast, application life length, anti-interference
Ability waits by force and has the characteristics that waterproof, is shockproof, corrosion-resistant.
Preferably, control element switchs in order to control, and the contact-making switch in the drive circuit of controlling switch and conveyer belt is connection
Dynamic switch.Detected when metal detection with inductance approach switch on conveyer belt there are during metallics, control signal can be sent,
Controlling switch is set to disconnect the contact-making switch in the drive circuit of conveyer belt, so that conveyer belt is shut down.
Button 4 is additionally provided with outside contact-making switch KM, after staff removes the metallics on conveyer belt, is pressed
Button 4, contact-making switch KM closures, conveyer belt resume operation.
It is different in view of the width of conveyer belt, for wider conveyer belt, a metal detection inductance approach switch
The width range of conveyer belt can not be covered, therefore, can set multiple metal detection inductance types are close to open below conveyer belt
Close.Multiple metal detection inductance types connect close to switch in parallel, the output terminal of each metal detection inductance approach switch
It is connected to a controlling switch.
For example, the width of the broken preceding conveyer belt of Ore Transportation equipment is more than 800 millimeters, the angle of inclination of conveyer belt compared with
Greatly, it is 18 °, haul distance is only 13 meters, and conveyer belt corridor is vacantly high, is a vibrating feeder below conveyer belt corridor, equipment is matched somebody with somebody
Put compact, belt widths are wider, for this reason, three metal detection inductance approach switches can be set below conveyer belt.
Three metal detections are triangularly arranged with inductance approach switch is arranged at the lower section of the conveyer belt.So arrangement can be most
The width for covering whole conveyer belt of limits, three close switches and the normal work that do not influence each other.So that it is guaranteed that to ore
When those weak ferromagnetism metals are mixed into raw material, belt-conveying can be stopped in time and manually detected, leakage will not be occurred by, which ensuring that, picks
Phenomenon.
It is understood that in other embodiments, width of three metal detection inductance approach switches along conveyor
Degree direction is arranged in the lower section of the conveyer belt.
Ore Transportation equipment provided in this embodiment, efficiently solves that traditional deironing apparatus reliable operation degree is low, failure
Shut down frequently, the accident treatment time is long, it is inconvenient to safeguard, it is difficult to detect the various technologies such as weak magnetic metallics (such as teeth)
Topic, realizes the stable operation for ore deposit feeding system, reduces the spare parts consumptions such as motor and equipment failure rate, also pressed for high stable
When feeding create good condition, achieve considerable economic benefit, there is great dissemination.
