Description
Technical field
The utility model relates to a kind of printing and dyeing assistant agitator, belongs to technical field of chemical.
Background technology
In printing and dyeing assistant production process, primary raw material is starch, starch fully need to be dissolved in water, in whole process, nearly all need heating, and holding temperature is 60 to 80 degrees Celsius of left and right.And existing agitator does not obviously have this function.
Summary of the invention
The utility model is that the technical problem solving is: propose one and can realize temperature controlled agitator.
In order to solve the problems of the technologies described above, the technical scheme the utility model proposes is: a kind of printing and dyeing assistant agitator, comprise cylinder body, be positioned at the blade of described cylinder body and for driving the motor of described blade, it is characterized in that, described inboard wall of cylinder block is provided with electrical heating wire and temperature sensor; The output of described temperature sensor is connected to the positive input of a comparator, and the reverse input end of described comparator is connected with the bleeder circuit of a fixed value resistance and adjustable resistance composition; The output of described comparator is connected with the base stage of a triode switch; The collector and emitter of described triode switch is connected and is connected dc source with the coil of a relay; The contact of described relay is connected between described electrical heating wire and AC power.
The utility model further improves and is: described temperature sensor comprises, the electric bridge of a thermo-sensitive resistor and three fixed value resistance compositions; The input of described electric bridge is connected with power supply; The output of described electric bridge is the output of described temperature sensor.
The utility model further improves and is: between described temperature sensor and described comparator, be connected with wave filter.
The printing and dyeing assistant agitator that the utility model provides, checks temperature by temperature sensor, then, after comparator, decides the on off operating mode of electrical heating wire by control relay, thereby reaches temperature controlled object; Adjust adjustable resistance and can change the input threshold value of comparator, and then can change temperature value in agitator.Arranging of resistance bridge can ensure that temperature sensor has higher precision, and wave filter can filter out interference, prevents that electrical heating wire from damaging because break-make frequency is too high.
Brief description of the drawings
Fig. 1 is preferred embodiment plan structure schematic diagram of the utility model.
Fig. 2 is the electrical block diagram of Fig. 1.
Number in the figure is schematically as follows: 1-cylinder body, 2-blade, 3-motor, 4-electrical heating wire, 5-temperature sensor.
Detailed description of the invention
Embodiment
The printing and dyeing assistant agitator of the present embodiment, as depicted in figs. 1 and 2, comprises cylinder body 1, is positioned at the blade 2 of cylinder body 1 and the motor 3 for driven vane 2, and cylinder body 1 inwall is provided with electrical heating wire 4 and temperature sensor 5; The output of temperature sensor 5 is connected to the positive input of a comparator U1, and the reverse input end of comparator U1 is connected with the bleeder circuit of a fixed value resistance R 5 and adjustable resistance R6 composition; The output of comparator is connected with the base stage of a triode Q1 switch; The collector and emitter of triode Q1 switch is connected and is connected dc source with the coil of a relay ZA1; The contact of relay ZA1 is connected between electrical heating wire 4 and AC power, and this circuit is also in series with fuse FU simultaneously.
Temperature sensor 5 in the present embodiment comprises, the electric bridge of thermo-sensitive resistor R1 and three fixed value resistances (R2, R3 and R4) composition; The input of electric bridge is connected with power supply; The output of electric bridge is the output of temperature sensor 5.
In order to prevent that break-make is damaged electrical heating wire 4 frequently, between temperature sensor 5 and comparator, be connected with filter capacitor C1.
When work, can, by regulating adjustable resistance R6 to change the input value of U1, change point thereby change U1 output state.5 of temperature sensors are according to temperature difference, electric bridge is exported different voltage, through the comparison of comparator U1, in the time of the voltage height of electric bridge output and the voltage of bleeder circuit, comparator exports " 1 " is also high level, thereby drive triode Q1, triode Q1 drives relay ZA1 again, finally can realize movingization and adjustable temperature control.
The concrete technical scheme being not limited to described in above-described embodiment of the present utility model, all employings are equal to replaces the technical scheme forming and is the protection domain that the utility model requires.
