Abstract
The utility model provides a temperature control system for an industrial furnace. The temperature control system for the industrial furnace comprises a temperature detector, a sensor, the industrial furnace and a programmable logic controller (PLC). The temperature detector is placed inside a hearth of the industrial furnace, and is electrically connected with the PLC through the sensor. The PLC is electrically connected with the industrial furnace, and also controls opening and closing of the industrial furnace. The temperature inside the hearth of the industrial furnace is controlled through the temperature detector, and the temperature detector outputs signals to the PLC. The PLC controls power-on and power-off of a heating device of the industrial furnace and opening of a furnace door of the industrial furnace, and therefore the temperature inside the furnace is reduced, the problems that the temperature inside the furnace is two high when the furnace is heated, and accordingly heating pieces are damaged are solved, potential safety hazard is reduced and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of temperature control system, relates in particular to a kind of temperature control system of used for industrial furnace.
Background technology
Industrial heating furnace, pass through burning combustible gas or energising when work, object to the need heating heats, but in when heating due to the temperature conditions of not knowing in stove, can't process according to situation, easily cause excess Temperature in stove, damaging needs heated parts, and has potential safety hazard.Therefore, the system of a control inside heating furnace temperature of design just seems particularly important.
The utility model content
The purpose of this utility model is to provide a kind of temperature control system of used for industrial furnace, by the detection to temperature in stove, controls the break-make of the heater in industrial furnace, the problem that the heating member that when having solved industrial furnace work, in stove, excess Temperature causes damages.
In order to address the above problem, the utility model provides a kind of temperature control system of used for industrial furnace, comprise Temperature Detector, sensor, industrial furnace and PLC controller, described Temperature Detector is arranged in the burner hearth of industrial furnace, Temperature Detector is electrically connected to the PLC controller by sensor, described PLC controller is electrically connected to industrial furnace, and the PLC controller is also controlled the stove door switch of industrial furnace.
Further improve and be: described industrial furnace comprises burner hearth, heater and fire door, when in the burner hearth of described industrial furnace, temperature surpasses setting value, Temperature Detector is sensed temperature in stove, send signal to sensor, sensor transfers signals in the PLC controller, the PLC controller is controlled the heater stop work of industrial furnace, and controls the oven door opening of industrial furnace, with exhaust of hot air out.
Further improve and be: described PLC controller is by Control industrial furnace heating and fire door.
The beneficial effects of the utility model: detect temperature in the industrial furnace burner hearth by Temperature Detector, output signal to the PLC controller, the break-make of the heater of PLC controller control industrial furnace and the unlatching of fire door, reduce temperature in stove, excess Temperature in stove when having solved heating, the problem that causes heating member to damage, and reduced potential safety hazard, improved operating efficiency.
Description of drawings
Fig. 1 is control sketch of the present utility model.
Fig. 2 is the left view of the utility model industrial furnace.
Wherein: 1-burner hearth, 2-heater, 3-fire door.
The specific embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
As shown in Figure 1, the present embodiment provides a kind of temperature control system of used for industrial furnace, comprise Temperature Detector, sensor, industrial furnace and PLC controller, described Temperature Detector is arranged in the burner hearth 1 of industrial furnace, Temperature Detector is electrically connected to the PLC controller by sensor, described PLC controller is electrically connected to industrial furnace, and the PLC controller is also controlled fire door 3 switches of industrial furnace.Described PLC controller is by Control industrial furnace heating 2 and fire door 3.
Described industrial furnace comprises burner hearth 1, heater 2 and fire door 3, when the interior temperature of burner hearth 1 of described industrial furnace surpasses setting value, Temperature Detector is sensed temperature in stove, send signal to sensor, sensor transfers signals in the PLC controller, the heater 2 that the PLC controller is controlled industrial furnace quits work, and the fire door 3 of controlling industrial furnace opens, with exhaust of hot air out.
Detect the interior temperature of industrial furnace burner hearth 1 by Temperature Detector, output signal to the PLC controller, the break-make of the heater 2 of PLC controller control industrial furnace and the unlatching of fire door, reduce temperature in stove, excess Temperature in stove when having solved heating, the problem that causes heating member to damage, and reduced potential safety hazard, improved operating efficiency.
