Description
Technical field
The utility model relates to a kind of temperature measuring equipment, especially relates to a kind of interior temperature of measurement dissolving stove that is used for to carry out temperature controlled temperature measuring equipment, belongs to the thermometric instruments technical field.
Background technology
At present, temperature survey in the dissolving stove is mainly by manually-operated, be that the operator need extend into temperature sensing device in the molten steel of dissolving in the stove and carries out temperature survey, this kind thermometric mode is at first from security consideration: because the temperature of the molten steel in the dissolving stove is than higher, the scald incident takes place easily, safety guarantee is bad, and for non-ferrous metal, the workman very easily causes employment injuries when operation; In addition, temperature sensing device directly contacts the molten steel of high temperature, and chemical reaction easily takes place, and causes loss, and cost is higher, can not in time obtain temperature in the stove, easily causes overtemperature overload damage body of heater.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of safe, easy to operate, dissolving stove automatic temperature measurement device that cost is low.
The utility model is achieved through the following technical solutions:
A kind of dissolving stove automatic temperature measurement device, it is characterized in that, it comprises thermopair, temperature compensation line, metal stationary pipes, holder and temperature measurement-control instrument, wherein, thermopair is connected with the temperature compensation line by terminal box, the other end of temperature compensation line then is connected with temperature measurement-control instrument, above-mentioned metal stationary pipes is enclosed within the outside of thermopair, and be fixed on the holder, and its low side is connected with terminal box, in addition, the measurement end of above-mentioned thermopair extend into bottom of furnace body, and it is positioned at the bottom of body of heater fire resistive material.
In addition, also be with the graphite sheath, be used to protect the measurement end of thermopair in the measurement end of thermopair.
And above-mentioned temperature measurement-control instrument comprises PLC controller, pushbutton switch and display screen, and wherein display screen and pushbutton switch are communicated with the PLC controller, and in order to realize the real-time control to the automatic temperature measurement device, wherein, pushbutton switch comprises starting switch and off switch.
Further, also be provided with warning device on the above-mentioned temperature measurement-control instrument, warning device can for hummer its by being communicated with the PLC controller, realize the warning function of automatic temperature measurement device.
Automatically report to the police when temperature surpass to be set boundary, power-off protection automatically, automatic constant-temperature calibration control.
The beneficial effects of the utility model are: the utility model is arranged on bottom of furnace body; to realize the measurement of temperature in the stove; can effectively avoid because directly the contact molten steel causes operator's security incident; the problem of employment injuries and measurement mechanism loss; in addition; by PLC controller in the temperature measurement-control instrument and warning device etc.; when temperature surpasses the boundary of setting; can realize automatic warning; automatic power-off protection; automatic constant-temperature calibration etc.; temperature controlling when having improved the calciner melting makes body of heater can not cause damaging because of the high temperature overload, and owing to realized robotization; improve work efficiency greatly, saved human cost simultaneously.
