Description
Technical field
This utility model belongs to pharmacy sterilizing installation technical field, is specifically related to a kind of temperature control equipment for novel dry heat sterilizer.
Background technology
Dry heat sterilizer has a wide range of applications in medical industry, and the temperature of the dry heat sterilizer of most domestic is controlled and still adopted solid-state relay to add the method for temperature control instrument at present, by a temperature probe, temperature in steriliser is measured, and then realizes controlling.But, this kind of method ignored the problem of temperature distributing disproportionation in steriliser, only regulates and controls the temperature conditions of a certain fixed position in steriliser, can not guarantee that the temperature of all positions in steriliser all can reach sterilising temp, will there is so the halfway situation of sterilizing, cause adverse consequences.
The utility model content
For solving the problems of the technologies described above, it is a kind of simple in structure applicable that this utility model provides, and can accurately control the dry heat sterilizer temperature control equipment of temperature.
Dry heat sterilizer temperature control equipment described in the utility model, comprise steriliser inner room, controllable silicon electric governor, electric heating system, upper temperature acquisition system, lower temperature acquisition system, detect control system and steriliser main body; Wherein, detect control system and comprise PLC control system and PID control system, upper temperature acquisition system and lower temperature acquisition system are positioned at the steriliser chamber interior, electric heating system is fixed in the steriliser main body inner wall, detecting control system is connected with upper temperature acquisition system, lower temperature acquisition system and controllable silicon electric governor respectively in the steriliser outside, the controllable silicon electric governor is positioned at steriliser main body outside, with electric heating system, is connected simultaneously.
The preferential selection of upper temperature acquisition system is positioned at steriliser inner room top, for gathering steriliser inner room head temperature.
The preferential selection of lower temperature acquisition system is positioned at bottom the steriliser inner room, for gathering steriliser inner room bottom temp.
The external 380V alternating current of the preferential selection of controllable silicon electric governor.
This utility model adopts the temperature regulation mechanism of two-part.At first, the interior room temperature of upper temperature acquisition system and lower temperature acquisition system Real-time Collection steriliser also feeds back to the detection control system, detect the PLC control system of control system through computing relatively, maximum and minima in the middle of determining, in steriliser inner room temperature-rise period, detect control system and regulate controllable silicon electric governor control electrical heating amount for 100% of heating general power, until the maximum temperature value reaches sterilising temp.Then, detect the PID control system output 0-10V Control of Voltage controllable silicon electric governor of control system and control electrical heating power, by minimum temperature, controlled, now in dry heat sterilizer, temperature enters the fine setting stage, through cushioning after a while, continue to heat up, the minimum temperature in temperature acquisition system arrives that sterilising temp is laggard enters the sterilizing stage until sterilizing finishes.
Compared with prior art, the utlity model has following beneficial effect:
Debugging rapidly, simple and practical, can accurately control the temperature of steriliser inner room, homoiothermic by stagewise and selection lowest temperature is controlled, and makes the sterilizer chamber temperature rise gently, and finally is stabilized in a relative steady state value, thereby realize the accurate control of temperature, realize the thoroughly effect of sterilization.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, steriliser inner room, 2, the controllable silicon electric governor, 3, electric heating system, 4, upper temperature acquisition system, 5, detect control system, 6, the steriliser main body, 7, lower temperature acquisition system.
The specific embodiment
This utility model embodiment 1, referring to Fig. 1, is described further this utility model below in conjunction with accompanying drawing:
Dry heat sterilizer temperature control equipment described in the utility model, comprise steriliser inner room 1, controllable silicon electric governor 2, electric heating system 3, upper temperature acquisition system 4, lower temperature acquisition system 7, detect control system 5 and steriliser main body 6; Detect control system 5 and comprise PLC control system and PID control system, upper temperature acquisition system 4 and lower temperature acquisition system 7 are positioned at steriliser inner room 1 inside, electric heating system 3 is fixed in steriliser main body 6 inwalls, detecting control system 5 is connected with upper temperature acquisition system 4, lower temperature acquisition system 7 and controllable silicon electric governor 2 respectively in the steriliser outside, controllable silicon electric governor 2 is positioned at steriliser main body 6 outsides, with electric heating system 3, is connected simultaneously; Upper temperature acquisition system is positioned at steriliser inner room top, for gathering steriliser inner room head temperature; Lower temperature acquisition system is positioned at steriliser inner room bottom, for gathering steriliser inner room bottom temp; The external 380V alternating current of controllable silicon electric governor.
During this utility model work, temperature is adopted to the regulative mode of two-part, debugging rapidly, simple and practical.At first, upper temperature acquisition system 4 and lower temperature acquisition system 7 Real-time Collection steriliser inner room 1 temperature also feed back to detection control system 5, detect control system PLC through computing relatively, maximum and minima in the middle of determining, in steriliser inner room 1 temperature-rise period, detect control system and regulate electric governor 2 control electrical heating amounts for 100% of heating general power, until the maximum temperature value reaches sterilising temp.Then, detecting control system 5 adopts the PID mode to export 0-10V Control of Voltage controllable silicon electric governor 2 control electrical heating powers, by minimum temperature, controlled, enter the fine setting stage, in steriliser, room temperature rises gently, until minimum temperature reaches sterilising temp, enters sterilization phase until sterilizing finishes, the fine setting stage has been realized the accurate control of temperature, has guaranteed bactericidal effect thoroughly.
