Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, immediate quenching equipment forms primarily of quenching bath 100, charging guipure 200 and discharging guipure 300.Oil plant is filled with in quenching bath.During work, heat material is delivered in quenching bath by the charging guipure of continuous running, and heat material carries out reaction with the oil plant in quenching bath and realizes quenching, and the heat material after quenching transports through discharging mesh-belt conveying.During work, if the stall of discharging guipure, the heat material so sent into by charging guipure can accumulate in the top of discharging guipure, and heat distributes in a large number and causes the oil temperature at this place to rise, and easily occurs security incident.
In order to avoid the generation of above problem, only need the stall situation detecting discharging guipure in time.Warning system of the present invention can realize above function.Particularly, see figures.1.and.2, warning system of the present invention comprises buting iron 1, first inductor 2, second inductor 3, very first time relay 4, second time relay 5, first alarm switch 6, second alarm switch 7 and alarm lamp 8 etc.
Buting iron 1 is arranged on discharging guipure, and can follow discharging guipure and rotate, the rotation period of buting iron 1 is identical with discharging guipure.Such as, be 20s when the rotation time of one week of discharging guipure, the time that so buting iron 1 rotates one week is also 20s.First inductor 2 and the second inductor 3 are fixed on outside discharging guipure, and both can not follow discharging guipure and rotate.When buting iron 1 follow discharging guipure turn to position near the first inductor 2 and the second inductor 3 time, buting iron 1 can block the inductor of correspondence.The normally closed proximity switch opened when first inductor 2 is blocked by buting iron 1, second inductor 3 often opens proximity switch for what close when being blocked by buting iron 1, namely the first inductor 2 and the second inductor 3 can carry out state switching when being blocked by buting iron 1 and when not blocked by buting iron 1, wherein the first inductor 2 is open mode when being blocked by buting iron 1, it is then closure state when not being blocked, second inductor 3 is closure state when being blocked by buting iron 1, is then open mode when not being blocked.First inductor 2 and the second inductor 3 are preferably disposed on adjacent position outside discharging guipure.
The triggered time of very first time relay 4 is not less than discharging guipure rotation period, and such as, when discharging guipure rotation period is 20s, the triggered time of very first time relay 4 should be set to 20s or more.Very first time relay 4 and the first inductor 2 are composed in series the first triggering loop, and these first two ends of triggering loop are powered by direct current.During specific works, when the first inductor 2 closes, very first time relay 4 works, and starts timing; When first inductor 2 is opened, first triggers loop disconnects, and very first time relay 4 stops timing.
Triggered time of second time relay 5 is not less than when buting iron rotates blocked for the second inductor time, and such as, buting iron rotates in one week and has 3s and block the second inductor, and the triggered time of second time relay 5 should be set to more than 3s, as 5s.Second time relay 5 and the second inductor 3 form the second triggering loop, and these second two ends of triggering loop are powered by direct current.During specific works, when the second inductor 3 closes, second time relay 5 works, and starts timing; When second inductor 3 is opened, second triggers loop disconnects, and second time relay 5 stops timing.
First alarm switch 6 associates with very first time relay 4, controls by very first time relay 4.Particularly, when very first time relay 4 meets timing condition triggering, the first alarm switch 6 can be converted to closure state from open mode.
Second alarm switch 7 associates with second time relay 5, controls by second time relay 5.Particularly, when second time relay 5 meets timing condition triggering, the second alarm switch 7 can be converted to closure state from open mode.
After first alarm switch 6 and the second alarm switch 7 are in parallel and alarm lamp 8 be composed in series alarm circuit.The two ends of this alarm circuit are powered by direct current.When at least one in the first alarm switch 6 and the second alarm switch 7 is closed, alarm lamp 8 can obtain electric work, reports to the police.
Suppose that the time that discharging guipure rotates one week is 20s, so set the triggered time of very first time relay as 22s, the triggered time of second time relay is 5s.When discharging guipure starts, buting iron is followed discharging guipure and is rotated.The rotation period of buting iron is 20s.Along with the rotation of buting iron, the first inductor and the second inductor can constantly switch being blocked state and not being blocked between state.
Under normal condition, first inductor lasting duration in closed state can be less than 20s, and very first time relay can not trigger, and the second inductor duration in closed state can be less than 5s, second time relay also can not trigger, and therefore alarm lamp can not work.
When causing the stall of discharging guipure when breaking down, suppose that buting iron is parked in outside inductor present position, so the first inductor can continue to close, after the timing time of very first time relay is greater than its triggered time 20s, first alarm switch can be triggered closed, orders about alarm lamp work.Suppose that buting iron is parked in inductor present position place, so the second inductor can continue to close, and after the timing time of second time relay is greater than its triggered time 5s, the second alarm switch can be triggered closed, orders about alarm lamp work.Utilize with upper type, no matter buting iron is parked in where, and warning system all can be reported to the police automatically.
In order to avoid during work, quenching bath high oil temperature produces dangerous, warning system of the present invention can be configured with high temperature alarm function further.Particularly, the present invention is provided with temperature control alarming switch 9 further, and temperature control alarming switch 9 is in parallel with the first alarm switch 6 and the second alarm switch 7.This temperature control alarming switch 9 carries out control by the sensor that is positioned at quenching bath oil plant and drives, and when high oil temperature, temperature control alarming switch 9 can be triggered closed, and alarm lamp work, realizes warning function.
In order to make systemic-function more perfect; the present invention can arrange stand-by time relay 10 and normally closed halt switch further; stand-by time relay 10 is in parallel with alarm lamp 8, and normally closed halt switch triggers by stand-by time Control, and normally closed halt switch is series on complete machine starting-up later time.When in the first alarm switch 6, second alarm switch 7 and temperature control alarming switch 9, any one is closed, except alarm lamp 8 works, stand-by time relay also can be triggered, thus control halt switch is opened, and entirety is quit work.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
