In this programme by the way of hanging lubricating cup 2, the internal stent that is arranged in oil drum 1 can be used also to support oil
Cup 2, but its flowing that may influence conduction oil 3, therefore it is not recommended that using.Bung 5 uses whole high-intensitive stainless steel
Metal plate production, guarantees that the vibration of blender does not influence complete equipment, and can support lubricating cup 2 and the wherein weight of experimental oil 4
Amount.The outer diameter precision of the size and lubricating cup 2 of placing the through-hole of lubricating cup 2 thereon is controlled when processing bung 5, also to guarantee to make
The shaking for not generating lubricating cup 2 in avoids the actual effect for influencing to test.
For sensor for detecting 3 temperature of conduction oil and 4 temperature of experimental oil respectively, it includes the bucket being set to apart from oil drum 1
The conduction oil temperature probe 10 that is in contact at a certain distance from wall and with conduction oil 3 is set to 2 center of lubricating cup and connects with experimental oil 4
The experimental oil temperature probe 11 of touching.Usually according on the basis of the depth of conduction oil 3 or experimental oil 4, corresponding temperature probe is arranged
Near 0.618 times of position of pasta total height.Sensor can be installed by hang.
In addition, the thermostatical oil bath can also include for hanging setting sample rack 16 and/or being set to oil for experiment sample 17
The oil drain pan 15 of 1 bottom of bucket, so as to conveniently hang experiment sample 17 and the processing to sample after experiment.And the present embodiment
Middle setting bracket 12 is for hanging setting sensor and blender.
The size of each part of the above thermostatical oil bath can according to need customization, the volume of usual experimental oil 4 and conduction oil 3
Than about 1:4.
Control circuit is connected with heater 8, blender, sensor respectively.As shown in figures 4 and 5, control circuit
Including power supply line, blender control module and heater control module.
Power supply line electric energy needed for external power supply is connected to provide comprising phase line and zero curve.
Blender control module is connected in power supply line, is also connected with blender, for controlling blender starting work
Or it stops working, and issue status signal in blender steady operation.Blender control module includes and power supply line and stirring
Machine is connected and is capable of the blender controller of output status signal.
Heater control module is connected with power supply line, blender control module, sensor respectively, it is used to be based on state
Signal control heater 8 starts work and is later than blender, stops working earlier than blender, or detects conduction oil in sensor
Control heater 8 stops working when 3 temperature or the temperature of experimental oil 4 are more than corresponding setting value.Heater control module includes
First intermediate relay 2KA1, the second intermediate relay 2KA2, first contactor 1KM2, heater controller and temp controlled meter.Its
Middle temp controlled meter is connected with sensor and detects the temperature of conduction oil 3 in sensor or the temperature of experimental oil 4 is more than corresponding to set
Oil temperature is exported when definite value detects signal.Since sensor includes two temperature probes, respectively conduction oil temperature probe 10 and reality
Oily temperature probe 11 is tested, therefore they respectively correspond and are provided with temp controlled meter, respectively conduction oil temp controlled meter and experimental oil temp controlled meter.The
The coil of one intermediate relay 2KA1 is connected with power supply line, and the coil of the second intermediate relay 2KA2 is connected simultaneously with temp controlled meter
Receive oil temperature detect signal, the normally opened node of the first intermediate relay 2KA1, the second intermediate relay 2KA2 normally closed node and
The coil of first contactor 1KM2 is connected in series and is connected and reception state signal with blender controller, first contactor 1KM2
Normally opened node, heater controller, heater be connected in series and be connected with power supply line.
In addition, control circuit can also include second contactor 1KM1 and multiple indicator lights.Second contactor 1KM1's
Coil is connected with power supply line, and its normally opened contact is then arranged on the power supply line in front of power supply line blender controller.Instruction
Lamp is included connection power work indicator light on the power line, is connected with blender controller and is lighted based on status signal
Work light, the heating work indicator light being connected with heater 8 etc. are stirred, the simultaneously base that is connected with temp controlled meter can also be set
In the overtemperature alarm that oil temperature detects signal and alarms.
In the thermostatical oil bath course of work, the starting of blender need to cooperate heater 8 and sensor, can use oncontacting
Point solid-state relay and heating PID fuzzy control are realized and stablize, uniformly, accurately heat.It must before starting heater 8 works
Blender need first be started, only blender could 8 power supply of turn on automatically heater after working normally.As blender breaks down
It has no idea to start computer heating control after alarm.In heating process, sensor one detects overtemperature (such as larger than set temperature 3
DEG C), it is switched off 8 power supply of heater and stops heating, and issue alarm signal, at this point, blender need to continue to operate normally, prevent
Conduction oil 3 generates coking on heater 8 after overtemperature.Heating is automatically cut off if blender failure in the process of running
8 power supply of device stops heating.
Specific in above-mentioned control circuit, when connecting external power supply and after connecting switch 1Q1, second contactor 1KM1's
Coil obtains electric, so that its normally opened contact 1KM1 is closed, power work indicator light lighted, and turns off the switch 1Q2, blender controller control
The decelerating motor 6 of blender processed starts work.After 6 the operation is stable of decelerating motor, blender controller output status signal, and
Light stirring work light.Meanwhile after closure switch 2QA1, the coil of the first intermediate relay 2KA1 obtain it is electric so that
The normally opened node of one intermediate relay 2KA1 is closed, thus the normally opened node of the first intermediate relay 2KA1, the second intermediate relay
The series via that the normally closed node of device 2KA2 and the coil of first contactor 1KM2 are constituted obtains status signal, so that the first contact
The normally opened node of device 1KM2 is closed, then heater controller obtains electric and controls the start-up operation of heater 8.Two thermometrics of sensor
Probe detects the temperature of conduction oil 3 and experimental oil 4 respectively, when the temperature detected is more than the setting value in corresponding temp controlled meter,
Temp controlled meter exports oil temperature and detects signal.Overtemperature alarm is alarmed at this time, and the coil of the second intermediate relay AKA2 obtains
Electricity, so that its normally closed node 2KA2 is disconnected, then the coil losing electricity of first contactor 1KM2, to disconnect its normally opened node
1KM2 makes heater 8 stop working, and blender works on.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
