Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of feeder fracture warning device, comprise feed hopper, be arranged on the casing of feed hopper one side, be connected the discharging opening of feed hopper below, the top barrel that it is characterized in that described discharging opening is provided with rotating valve, one end of rotating valve cooperates with the endoporus of discharging opening, the other end of rotating valve is provided with contact rod, extension spring, the medium position of rotating valve is established a hinge, and described contact rod cooperates with the two poles of the earth of the normal open switch of alarm circuit.The closure of rotating valve and unlatching are determined by the material in the feed hopper, when powder uninterruptedly passes through, under the gravity effect of powder, the end that rotating valve cooperates with the discharging opening endoporus turns to the below, discharging opening is unimpeded, when feed hopper stops into powder, rotating valve is fulcrum with the hinge, under the pulling force of extension spring, by lever principle, the end that rotating valve cooperates with the discharging opening endoporus turns to the top and closely cooperates with the discharging opening endoporus, prevents that air from entering reduction furnace, contact rod is connected warning device simultaneously, reminds the operator.
As preferably, described rotating valve is arranged in the casing, is provided with powder blocking plate between the top barrel of rotating valve and discharging opening.Rotating valve and accessory thereof are arranged in the casing, cabinet design becomes the sealing shape, rotating valve is when opening, do not communicate between discharging opening top barrel and the casing yet, the upper end of powder blocking plate and the seamless welding of discharging opening top barrel, hinge can be arranged on the lower end of striker plate, adopts seamless connection equally.
As preferably, the top barrel of described discharging opening is provided with breach towards a side of casing, and rotating valve is when being in the position of opening discharging opening, and the end that rotating valve cooperates with the discharging opening endoporus is positioned within the discharging opening endoporus of breach lower end.The height of breach and width are as the criterion the operating position up and down with rotating valve, and rotating valve and discharging opening endoporus cooperation place are provided with sealing device.
As preferably, an end of described extension spring is fixed on the end of rotating valve, and the other end of extension spring is fixed on the casing, and the two ends of hinge are fixed on the casing.It is standard that the intensity of extension spring can be opened rotating valve with the inlet amount of feed hopper design, if hinge is fixed on the striker plate, two ends can be fixed on the casing.
As preferably, be provided with indicator lamp in the described alarm circuit.Also can be provided with the warning loud-speaker.
As preferably, described rotating valve is fulcrum with the hinge, towards the weight of an end of discharging opening less than the weight that is provided with contact rod one end.Rotating valve is the boundary with the hinge, and an end weight that is provided with contact rod is heavy slightly, in time closes when helping not having powder, and the sensitivity of rotating valve also is improved, and does not have the effect that material is closed even also can play when spring failure.
Effective effect of the present invention is: when with feeder that reduction furnace is connected in the disconnected powder of powder after, valve is auto-closing under the effect of its deadweight and extension spring, stop air to enter in the reduction furnace effectively, keep the pure of furnace gas, by alarm lamp, operating personnel carrying out promptly and accurately operated accordingly.
Therefore, the utility model is a kind of reasonable in design, practical and convenient feeder fracture warning device.
