Abstract
The utility model provides a technical scheme for a PLC temperature control device of a box-type resistor furnace. In the temperature control device of the scheme, an internal temperature sensor is arranged in a furnace body; the internal temperature sensor is connected with a PLC programming control unit, a liquid crystal display is connected with the PLC programming control unit, the PLC programming control unit is connected with a PLC execution unit; the PLC execution unit controls a heater through a relay module; an external temperature sensor is arranged on the outer side of the furnace body; and the external temperature sensor is connected with the PLC programming control unit. The internal temperature sensor of the temperature control device of the scheme can timely detect the temperature inside the furnace, so as to control the heating capacity of a heating device, and the external temperature sensor outside the furnace can detect the problems of the furnace casing, so that the power supply of the heater can be cut off in case that the temperature is over-high, and danger is avoided. Therefore, the device realizes the automatic regulation, control and monitoring of the output power.
Description
Technical field
The utility model relates to a kind of chamber type electric resistance furnace, especially a kind of chamber type electric resistance furnace PLC temperature control equipment.
Background technology
In the prior art, known chamber type electric resistance furnace temperature regulating device all is general " temperature controller " control of producing with instrument manufacturer.General " temperature controller " that cause is produced at present has deficiency to the specialty control aspect of chamber type electric resistance furnace, as: operate loaded down with trivial details, input, output point is less relatively, and function singleness can't realize under same temperature control, the adjusting of multiple spot input, output and power output, control, monitoring, can't carry out version updating etc., and in the heating process, whole box body all can heating, object around very easily igniting, this is the existing in prior technology weak point.
Summary of the invention
The purpose of this utility model, be exactly at the existing in prior technology deficiency, and provide a kind of technical scheme of chamber type electric resistance furnace PLC temperature control equipment, the temperature control equipment of this scheme to comprise a plurality of internal temperature sensors that are arranged in the stove, can record the temperature in the stove timely, control the heating load of heater timely, stove is outside equipped with external temperature sensor, can record the problem of stove outer covering, when temperature is too high, cut off the power supply of heater, place dangerous generation.Automatic adjusting, control, the monitoring of power output have been realized.And can realize Long-distance Control or by calculating many controls, and can be at any time according to the version updating after customer requirements or the research and development upgrading by the PLC interface.
This programme is realized by following technical measures: a kind of chamber type electric resistance furnace PLC temperature control equipment, include the body of heater that has fire door, the characteristics of this programme are: be provided with a plurality of internal temperature sensors in the described body of heater, described internal temperature sensor is connected with PLC programming Control unit, described PLC programming Control unit is connected with the PLC performance element, described PLC performance element is by being provided with a plurality of internal temperature sensors in the described body of heater of relay module control heater, described internal temperature sensor is connected with the PLC programming Control unit that has guidance panel, there is a LCD to be connected with described PLC programming Control unit, described PLC programming Control unit is connected with the PLC performance element, described PLC performance element is by the relay module control heater, in addition, also be provided with a plurality of external temperature sensors in the described body of heater outside, described external temperature sensor is connected with PLC programming Control unit.The opening part of described body of heater and fire door is provided with a travel switch, the switch of described travel switch control PLC programming Control unit.
The beneficial effect of this programme can be learnt according to the narration to such scheme, by automatic adjusting, the control of the related data on the setting operation panel by PLC programming Control unit and PLC performance element realization power, realizes monitoring in real time by liquid crystal display.PLC programming Control unit can be provided with corresponding interface, realizes that Long-distance Control reaches the machine control by many All-China Federation of Taiwan Compatriots of calculating, and can carry out remote upgrade to this temperature control system by this interface.In stove, be provided with internal temperature sensor, can record the problem in the stove, and send the signal of surveying to PLC programming Control unit, PLC programming Control unit controls heater; Stove is outside equipped with external temperature sensor, can record the temperature of housing, and when skin temperature was too high, external temperature sensor transmitted signal and gives PLC programming Control unit, and PLC programming Control unit cuts off the power supply of heater, stops heating, prevents dangerous generation.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
