The utility model discloses be equipped with check weighing speed adjusting device, make this mediation cauldron can according to cauldron internal portion wait to mediate the rotational speed of the weight automatically regulated stirring rake of material, guarantee the consonant high efficiency.
Description
Technical field
The utility model relates to a kind of mixing plant, and more particularly, it relates to a kind of Weight measuring type mediation still.
Background technology
The still that is in harmonious proportion is widely used in the mediation reaction of various chemical products in manufacturing process, for different raw materials is reconciled into finished product according to a certain percentage.The still that is in harmonious proportion mainly comprises kettle.The paddle being arranged on kettle inside and the motor driving paddle to rotate.
Sometimes, the weight adding the zonal harmonics material of mediation still can be different, when the weight of slow-witted blending stock is less, it is shorter to be in harmonious proportion the time evenly used, and when the weight of slow-witted blending stock is larger, will be in harmonious proportion and evenly just need to spend the more time, and large batch of production often wishes zonal harmonics material to be in harmonious proportion quickly.And current mediation still, when blending stock is heavier, although can the rotating speed of its paddle of Artificial Control make mediation accelerate, not by the weight auto-associating of the rotating speed of paddle and slow-witted blending stock, this mediation still does not possess the function of automatic speed regulation, and the actual flexibility used is slightly poor.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Weight measuring type mediation still, and this mediation still can regulate the rotating speed of paddle automatically according to the weight treating blending stock of kettle inside, ensure the high efficiency be in harmonious proportion.
For achieving the above object, the utility model provides following technical scheme:
A kind of Weight measuring type mediation still, the motor comprising kettle, be arranged on the paddle of kettle inside and drive paddle to rotate, described motor is double-speed motor, comprise high speed and low speed two grades, mediation still is also provided with check weighing arrangements for speed regulation, described check weighing arrangements for speed regulation for measure the inner weight until blending stock of kettle and until blending stock weight higher than control during predetermined value machine operation at high speeds and until blending stock weigh less than predetermined value time control machine operation under lower-speed state.
The utility model is set to further, and described check weighing arrangements for speed regulation comprise:
Check weighing module, described check weighing module for measure the inner weight until blending stock of kettle and until blending stock weight higher than send during predetermined value the first feedback signal and until blending stock weigh less than predetermined value time send the second feedback signal;
Controller, controls machine operation at high speeds and in response to the second feedback signal control machine operation under lower-speed state in response to the first feedback signal.
The utility model is set to further, and described check weighing module comprises pressure sensor and comparing unit, and between the base that mediation still is located at by described pressure sensor and the supporting surface at its place, the output of described pressure sensor is connected with the input of comparing unit.
Compared with prior art, the utility model has the advantages that: the utility model is equipped with check weighing arrangements for speed regulation, make this mediation still automatically can regulate the rotating speed of paddle according to the weight treating blending stock of kettle inside, ensure the high efficiency be in harmonious proportion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the circuit diagram of check weighing arrangements for speed regulation.
Description of reference numerals: 1, kettle; 2, base; 3, oar axle; 4, blade; 5, supporting surface; 6, pressure sensor.
Detailed description of the invention
As shown in Figure 1, pressure sensor 6 is provided with between the base 2 and the supporting surface 5 at its place of kettle 1, this pressure sensor 6 is voltage-type pressure sensor 6, pressure sensor 6 by the kettle 1 above it together with kettle 1 inside treat the gravity of blending stock be converted into voltage signal export.
As shown in Figure 2, be circuit theory diagrams of the present utility model, comparing unit comprises comparator A1 and comparator A2.Wherein, the output of pressure sensor 6 is connected with the reverse input end of the positive input of comparator A1 and comparator A2.The reverse input end of comparator A1 and the positive input input comparative voltage Vref of comparator A2.The output of comparator A1 is connected with the base stage of amplifying triode Q1 by resistance R1, triode Q1 is common emitter connection, power supply and coil KM1 is connected between the emitter stage of triode Q1 and colelctor electrode, what coil KM1 was corresponding is Double-speed motor controller " at a high speed " contact, the output of comparator A2 is connected with the base stage of amplifying triode Q2 by resistance R2, triode Q2 is also common emitter connection, be connected with power supply and coil KM2 between the emitter and collector of triode, what coil KM2 was corresponding is Double-speed motor controller " low speed " contact.
When the voltage that pressure sensor 6 exports is greater than predetermined value higher than the weight until blending stock of Vref(and kettle 1 inside) time, the output output voltage of comparator A1, just have the base stage of current direction triode Q1 subsequently, this electric current is flowing through coil KM1 after the amplification of triode Q1, the current strength of flowing through coil KM1 is enough to make coil KM1 will the adhesive of " at a high speed " contact, now, double-speed motor is operated in fast state; When the voltage that pressure sensor 6 exports is less than predetermined value lower than the weight until blending stock of Vref(and kettle 1 inside) time, the output output voltage of comparator A2, just have the base stage of current direction triode Q2 subsequently, this electric current is flowing through coil KM2 after the amplification of triode Q2, the current strength of flowing through coil KM2 is enough to make coil KM2 by the adhesive of " low speed " contact, now, double-speed motor is operated in lower-speed state.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
