Abstract
The utility model provides an automatic stabilizing system of temperature behind electrical heating biphenyl stove heating fault through increasing devices such as ac contactor normally open contact, temperature control instrument warning contact, ac contactor, backup heater, the effectual production large tracts of land that has avoided leading to because of biphenyl stove heating system trouble falls in temperature jumps the machine, has guaranteed production output and efficiency.
Description
Technical Field
The utility model relates to a temperature automatic stabilization system especially involves an automatic temperature stabilization system after electric heating biphenyl stove heating trouble, belongs to chemical fibre equipment field.
Background
In a chemical fiber plant, an electric heating biphenyl furnace is mostly used for providing heat preservation temperature for a spinning box body, normal production can be guaranteed only by stabilizing at a process set temperature value, in order to guarantee stability and convenient control of the temperature, the biphenyl furnace is simultaneously used by adopting a group of adjusting heating and a plurality of groups of auxiliary heating, the auxiliary heating of the biphenyl furnace is reserved in two groups, the biphenyl furnace is used after abnormal temperature deviation is guaranteed, the auxiliary heating is controlled by a manual switch, when the biphenyl furnace is in use and is not heated due to heating system faults, the temperature of the biphenyl furnace can be rapidly reduced, an operator cannot timely find and open the auxiliary heating, and therefore large-area trip accidents in production are caused, and production yield and efficiency are seriously affected.
Disclosure of Invention
The utility model provides an automatic stabilizing system of temperature behind electrical heating biphenyl stove heating fault through increasing devices such as ac contactor normally open contact, temperature control instrument warning contact, ac contactor, backup heater, the effectual production large tracts of land that has avoided leading to because of biphenyl stove heating system trouble falls in temperature jumps the machine, has guaranteed production output and efficiency.
The technical scheme of the utility model is that:
the utility model provides an automatic stabilizing system of temperature after electric heating biphenyl stove heating fault, includes temperature control instrument, exchange 220V power live wire, temperature sensor, biphenyl stove, solid state relay, exchange 220V power zero line, heater, its characterized in that still includes ac contactor normally open contact, temperature control instrument alarm contact, ac contactor, backup heater install inside the biphenyl stove, backup heater passes through the connection of electric lines ac contactor normally open contact, ac contactor normally open contact pass through the connection of electric lines ac 220V power live wire, temperature control instrument alarm contact one end pass through the connection of electric lines ac 220V power live wire, the other end passes through the connection of electric lines ac contactor, ac contactor pass through the connection of electric lines ac 220V power zero line.

Fig. 1 is a schematic structural diagram of an automatic temperature stabilizing system after a heating fault of an electric heating biphenyl furnace.
Detailed Description
The present invention will be further explained by the following embodiments, but the scope of the present invention is not limited to the embodiments.
As shown in figure 1, the system for automatically stabilizing the temperature of the electric heating biphenyl furnace after heating failure comprises a temperature control instrument 1, an AC 220V power live wire 2, a temperature sensor 3, a biphenyl furnace 4, a solid-state relay 5, an AC 220V power zero wire 9 and a heater 10, it is characterized by also comprising an alternating current contactor normally open contact 6, a temperature control instrument alarm contact 7, an alternating current contactor 8 and a standby heater 11, the standby heater 11 is arranged in the biphenyl furnace 4, the standby heater 11 is connected with the normally open contact 6 of the alternating current contactor through a wire, the normally open contact 6 of the alternating current contactor is connected with an alternating current 220V power supply live wire 2 through a wire, one end of the temperature control instrument alarm contact 7 is connected with an alternating current 220V power live wire 2 through a wire, the other end of the temperature control instrument alarm contact is connected with an alternating current contactor 8 through a wire, and the alternating current contactor 8 is connected with an alternating current 220V power zero line 9 through a wire.
When biphenyl stove 4 normally worked, temperature sensor 3 detected and transmitted the temperature in biphenyl stove 4 inside temperature control instrument 1, temperature control instrument 1 exported a control signal to solid state relay 5 after internal control, and 5 major loop switchings of solid state relay simultaneously, and exchanges 220V power live wire 2 simultaneously and for heater 10 power supply heating.
When the temperature control system of the biphenyl furnace breaks down, the heater 10 does not heat any more, the temperature of the biphenyl furnace 4 drops, when the temperature drops to a lower temperature limit alarm value set in the temperature control instrument 1, the alarm contact 7 of the temperature control instrument acts, the alternating current contactor 8 controls the loop to be electrified and act, the normally open contact 6 of the alternating current contactor acts and closes, the standby heater 11 is electrified and starts heating, the biphenyl furnace 4 recovers heating work, when the temperature sensor 3 detects that the internal temperature of the biphenyl furnace 4 reaches an upper temperature limit alarm value set in the temperature control instrument 1, the control loop stops working, the standby heater 11 stops heating, and therefore the operation is repeated, and the temperature of the biphenyl furnace 4 is ensured to be within a proper production process temperature value. The production large-area trip caused by temperature drop due to the fault of the heating system of the biphenyl furnace is effectively avoided, and the production yield and efficiency are ensured.
While the invention has been described in conjunction with the above embodiments, it will be understood by those skilled in the art that various changes may be made and parts may be substituted. Thus, it can be understood that: it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention. All changes and modifications that come within the scope of the appended claims are to be embraced therein without departing from the inventive concept.
