Abstract
The invention relates to an extremely hot temperature detection device for an electric heating energy-storage furnace. A plurality of groups of ropes or geometric bodies made of chosen appropriate mediums are arranged in a high-temperature region in the electric heating energy-storage furnace, and the end of each medium rope or geometric body is connected with a small hole arranged at the end of a movable support arm of a status indicator. Within a normal temperature range, the movable support arm of the status indicator is pulled by the medium ropes or the geometric bodies to compress a return spring so that the end of the movable support arm departs from a button of an overheat state output travel switch, the overheat state output travel switch is released at the moment, and the electric heating energy-storage furnace works normally. When the furnace temperature of the electric heating energy-storage furnace is overheated, under the effect of high temperature, the medium ropes or the geometric bodies lose structural strength and break, the end of the movable support arm is rotated anticlockwise under the effect of the return spring so that the button of the overheat state output travel switch is pressed, the overheat state output travel switch outputs signals to switch off a working power source of the electric heating energy-storage furnace, and the furnace temperature is prevented from rising continuously.

?
Described medium rope is lower than the rope that 1200 degrees centigrade metal and insulating materials fiber etc. are processed for the relatively hot melting temperatur.
Described positioning indicator is installed on the electric heating energy-storage furnace outer wall, by moving support arm, return spring, decide three of support arms part and form.The aperture of one end of moving support arm is connected with the end of medium rope or solid, the centre of moving support arm with decide fulcrum shaft and be connected, spacing by return spring; Under normal condition; The other end of moving support arm and the button of overtemperature state delivery stroke switch keep being at interval discharging the position, when abnormality occurring, and electric heating energy-storage stove furnace temperature overtemperature; Medium rope or solid lose the structural strength fracture under action of high temperature, and then overtemperature state stroke switch output signal cuts off the electric heating energy-storage furnaceman and makes power supply.
Described medium rope structure can be replaced by the medium solid; The medium solid is to be lower than 1200 degrees centigrade metal by hot melting temperature to process; Can be the geometry body of different shape, but holding state indicator return spring make overtemperature state delivery stroke switch be in release conditions when being lower than melting temperature.
Beneficial effect of the present invention is following:
The very hot temperature-detecting device of electric heating energy-storage stove of the present invention; Owing to adopted the dielectric material physical characteristic, it is simple in structure, dependable performance; When the electric heating energy-storage stove produces very hot temperature; Checkout gear output control signal is cut off the working power of electric heating energy-storage stove, to guarantee electric heating energy-storage stove safe and stable operation, prevents the generation of accident.
