Description
Technical field
The utility model relates to a kind of a kind of high temperature duplicate protection system for hot air sterilizer, for improving the security of hot air sterilizer, belongs to the design field of hot air sterilizer.
Background technology
At present, the high temperature protection of hot air sterilizer is all by detecting interior room temperature, and the contactor controlling heating tube realizes, and can not turn off if contactor breaks down, heating tube will be in the state always heated, and brings hidden danger to the safety of equipment.
The technical problems to be solved in the utility model is: provide a kind of high temperature duplicate protection system for hot air sterilizer, and its structure is simple, easy to use, provides reliable safety guarantee to equipment.
High temperature duplicate protection system on hot air sterilizer described in the utility model, comprise temp probe, temperature measurement control system, temperature switch, excitation trip unit, contactor, upper heating tube, side heating tube and isolating switch, temp probe is positioned at heating tube rear end, be connected with temperature measurement control system, the opening and closing of temperature measurement control system control contactor simultaneously; The detection probe of temperature switch is positioned at above the heating tube of side, and the control contact of simultaneous temperature switch controls excitation trip unit, and trip unit is used for shutdown device.
Sterilizer is in the temperature rise period, the signal of temperature measurement control system PLC and module acquires temp probe, control contactor adhesive, if temperature exceedes temperature upper limit, PLC will stop the output of control contactor, if contactor cannot disconnect because damaging, continuation raises, after reaching the limit value of temperature switch by the temperature in sterilizer, contact on temperature switch is by adhesive, excitation trip unit powers on simultaneously, and disconnected by the isolating switch controlling heating tube, stopping is heated by heating tube.Thus reach the object of high temperature protection.
The beneficial effects of the utility model are:
By duplicate protection, the security of equipment effectively can be improved.
Accompanying drawing explanation
Fig. 1 is systematic schematic diagram of the present utility model.
In figure: 1, temp probe; 2, temperature measurement control system; 3, temperature switch; 4, excitation trip unit; 5, contactor; 6, upper heating tube; 7, side heating tube; 8, isolating switch.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As described in Figure, high temperature duplicate protection system on hot air sterilizer described in the utility model, comprise temp probe 1, temperature measurement control system 2, temperature switch 3, excitation trip unit 4, contactor 5, upper heating tube 6, side heating tube 7 and isolating switch 8, temp probe 1 is positioned at heating tube 6 rear end, be connected with temperature measurement control system 2, the opening and closing of temperature measurement control system 2 control contactor 5 simultaneously; The detection probe of temperature switch 3 is positioned at above side heating tube 7, and the control contact of simultaneous temperature switch 3 controls excitation trip unit 4, and trip unit 4 is used for shutdown device 8.Temperature measurement control system 1 is PLC system.
The course of work:
The sterilizer temperature rise period, the temperature signal of temperature measurement control system 2 collecting temperature probe 1 detects the temperature around upper heating tube 6 and side heating tube 7, the adhesive of control contactor 5, if temperature exceedes the temperature upper limit that temperature measurement control system 1 is arranged, temperature measurement control system 2 exports stopping the signal of control contactor 5, if contactor 5 due to the reasons such as damage cannot deenergization connect, continuation raises by the temperature in sterilizer, when after the limit value reaching temperature switch 3, contact on temperature switch 3 is by adhesive, control excitation trip unit 4 to power on simultaneously, the isolating switch 8 controlling heating tube is disconnected, cut off the electricity supply, stopping is heated by heating tube 6 and 7, thus reach the object of high temperature protection.Which enhance the security of equipment.
