An agitating vane is arranged in the reaction kettle and driven by a motor; the inner wall of the reaction kettle is provided with an electric heating wire and a temperature sensor; the output end of the temperature sensor is connected to a positive-going input end of a comparator, and an inverted input end of the comparator is connected with a voltage division circuit consisting of a fixed value resistor and an adjustable resistor; the output end of the comparator is connected with a base electrode of a triode switch; a collector electrode and an emitting electrode of the triode switch are connected with a coil of a relay in serial and connected with a direct-current power supply; a contact of the relay is in serial connection between the electric heating wire and an alternating-current power supply. According to the printing and dyeing auxiliary reaction kettle, the temperature is examined through the temperature sensor, and the on-off state of the electric heating wire is determined by controlling the relay through the comparator, so that a purpose for controlling the temperature can be realized.
Description
Technical field
The present invention relates to a kind of printing and dyeing assistant reactor, belong to technical field of chemical.
Background technology
In printing and dyeing assistant production process, reactor is common equipment.Existing reactor all has heating function, and because auxiliary agent manufacturing technique requirent is not high, acceptable range of temperature can reach tens degrees Celsius.So what existing reactor had is only heating function.Even but the possibility that wide range of temperature has existence to exceed.But high precision temperature control equipment as too complicated, that cost is higher in fruit structure is lost more than gain again.
Summary of the invention
The present invention is that the technical problem solving is: propose a kind of temperature controlled reactor with low cost.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of printing and dyeing assistant reactor, is provided with stirring vane, described stirring vane is driven by motor in described reactor; Described reactor inwall 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 present invention 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.
Further improvement of the present invention is: between described temperature sensor and described comparator, be connected with wave filter.
A kind of printing and dyeing assistant reactor provided by the invention, by temperature sensor monitors temperature, then, after comparator, decides the on off operating mode of electrical heating wire, thereby reaches temperature controlled object by control relay; Adjust adjustable resistance and can change the input threshold value of comparator, and then can change reactor temperature value.Arranging of resistance bridge can guarantee 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.The present invention is simple in structure, with low cost, very effective.
Accompanying drawing explanation
Fig. 1 is preferred embodiment plan structure schematic diagram of the present invention.
Fig. 2 is the electrical block diagram of Fig. 1.
Number in the figure is schematically as follows: 1-reactor, 2-stirring vane, 3-motor, 4-electrical heating wire, 5-temperature sensor.
The specific embodiment
Embodiment
The printing and dyeing assistant reactor of the present embodiment, as depicted in figs. 1 and 2, comprises being positioned at the stirring vane 2 of reactor 1 and for driving the motor 3 of stirring vane 2, reactor 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.
In order to prevent that break-make is damaged electrical heating wire 4 frequently, between temperature sensor 5 and comparator U1, 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 present invention is not limited to the concrete technical scheme described in above-described embodiment, and the technical scheme that all employings are equal to replacement formation is the protection domain that the present invention requires.
