Abstract
The utility model discloses a furnace temperature control system which comprises a burner, a PLC (programmable logic controller) control unit and temperature sensors located in a furnace body, wherein the temperature sensors comprise a lower temperature sensor located at the bottom of the furnace body, a middle temperature sensor located in the middle of the furnace body and an upper temperature sensor located at the top of the furnace body; the lower temperature sensor, the middle temperature sensor and the upper temperature sensor are electrically connected with the PLC control unit respectively; and the PLC control unit is electrically connected with the burner. According to the furnace temperature control system, the lower temperature sensor located at the bottom of the furnace body, the middle temperature sensor located in the middle of the furnace body and the upper temperature sensor located at the top of the furnace body are arranged in the furnace body, accordingly, the temperature at the top, in the middle and at the bottom of the furnace body can be detected simultaneously, the temperature condition in the furnace body can be reflected comprehensively relatively, and control of the temperature in the furnace body is accurate relatively. The PLC control unit judges the temperature in the furnace and controls opening and closing of the burner pursuantly, so that the temperature in the furnace is in a suitable range.
Description
Technical field
The utility model belongs to the technical field of roaster.
Background technology
Roaster is widely used in casting industry, and roaster is synthesized and calcined to improve the performance of material by inorganic particle.In order to ensure the quality of synthetic and calcined product, temperature in body of heater need to be controlled in certain scope, existing roaster only in body of heater a place be provided with temperature sensor, can not comprehensively reflect the temperature conditions in body of heater, to temperature in body of heater not accurate enough control, thereby impact is synthetic and the quality of calcined product.
Utility model content
The utility model provides a kind of Furnace Temperature Control System, can solution must not comprehensively reflect the problem of the temperature conditions in body of heater.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of Furnace Temperature Control System, comprise burner, PLC control module and be positioned at the temperature sensor of body of heater, described temperature sensor comprise be arranged in bottom of furnace body lower temperature sensor, be positioned at the temperature sensor at body of heater middle part and be positioned at the upper temperature sensor at body of heater top, described lower temperature sensor, middle temperature sensor and upper temperature sensor are electrically connected with PLC control module respectively, and PLC control module is electrically connected with burner.
Compared with prior art, the utility model has the advantage of: in body of heater, be provided be arranged in bottom of furnace body lower temperature sensor, be positioned at the temperature sensor at body of heater middle part and be positioned at the upper temperature sensor at body of heater top, can detect the temperature of upper of furnace body, middle part and bottom simultaneously, can comparatively comprehensively reflect the temperature conditions in body of heater, comparatively accurate to the handle control of temperature in body of heater.PLC control module judges the temperature in stove, thus the startup of control combustion device and close so that stove in temperature in suitable scope.
Further, described PLC control module is provided with the display screen of displays temperature, can see intuitively the temperature conditions in body of heater.
Brief description of the drawings
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
As shown in Figure 1, a kind of Furnace Temperature Control System in the present embodiment, comprise burner 1, PLC control module 2 and be positioned at the temperature sensor of body of heater 7, described temperature sensor comprise be arranged in body of heater 7 bottoms lower temperature sensor 3, be positioned at the temperature sensor 4 at body of heater 7 middle parts and be positioned at the upper temperature sensor 5 at body of heater 7 tops, described lower temperature sensor 3, middle temperature sensor 4 and upper temperature sensor 5 are electrically connected with PLC control module 2 respectively, and PLC control module 2 is electrically connected with burner 1.Described PLC control module 2 is provided with the display screen 6 of displays temperature, can see intuitively the temperature conditions in body of heater 7.
Be arranged in the temperature that the lower temperature sensor 3 of body of heater 7 bottoms, the upper temperature sensor 5 that is positioned at the temperature sensor 4 at body of heater 7 middle parts and is positioned at body of heater 7 tops detect body of heater 7, and the temperature of detection is sent to PLC control module 2, PLC control module 2 judges whether the interior temperature of body of heater 7 meets required temperature.When the interior temperature of body of heater 7 is when temperature required, PLC control module 2 sends instruction and starts burner 1 and heat; When the interior temperature of body of heater 7 is when temperature required, PLC control module 2 sends instruction and suspends burner 1 and heat.
For a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
