Abstract
The invention relates to a determination method for kneading and uniform mixing of materials. the method is adopted to mainly solve the problem that kneading degree cannot be controlled accurately by judging kneading degree of materials based on artificial experience during wet mixing operation of materials by the use of a kneader in the prior art. The method provided by the invention comprises the following steps: sampling recording is carried out on instantaneous current of stirring paddles of a kneader during kneading of materials; when there is a sudden change in the current, the moment is taken as the starting time of the kneading reaction; and when the current is stable, the moment is taken as the end time of the kneading reaction. By the technical scheme, the above problem is solved well. The method can be used in the industrial production of kneading materials by the use of the kneader.
Description
Technical field
The present invention relates to a kind of method that material mixes of mediating that judges.
Background technology
Kneader is a kind of mixing plant that high-viscosity material is carried out to kneading, by the rotation of paddle, material in equipment tank is carried out circumferentially and radially two-way kneading, make material reach certain technological requirement, extensive in sector applications such as chemical industry, food, medicine, plastics, pigment.For example document CN201020581529.4 discloses a kind of pair of ∑ type blade kneader, and two blades are connected with a drive motor respectively, i.e. Double Motor Control.Document CN201220527163.1 discloses a kind of kneader, comprises kneader main body, drive motor, reducer casing, gear case, main shaft, secondary shaft, main paddle and secondary paddle; Wherein, drive motor is connected with reducer casing, and reducer casing is connected with gear case, and gear case is connected with main shaft, and the main shaft other end is connected with main paddle; Main shaft adopts gear to be connected with secondary shaft, and secondary shaft is connected with secondary paddle; Two paddle left and right of major-minor are parallel to be installed in kneader main body cylinder body; Main shaft and secondary shaft are major axis, and the helix angle of main paddle and secondary paddle is-45 °～-90 °.
The kneading process of high-viscosity material comprises dry blend wet mixing process.In wet mixing process, between different material, can there is peptization reaction.In prior art, kneading process is often by the quality that manually rule of thumb judges that material is mediated, because the difference of artificial judgment causes material to mediate situation excessive or not in place.
Summary of the invention
Technical matters to be solved by this invention is the quality that prior art is mediated by artificial experience judgement material while existing material to use kneader wet mixing operation, cannot accurately control and mediate the problem of carrying out degree, provide a kind of new judgement to mediate the method that material mixes.The method have control accurately, stable operation, reduction labour intensity, the feature of enhancing productivity.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of method that judges that kneading material mixes, comprises that the momentary current of stirring paddle of kneading machine when material is mediated carries out the step of sample record; When current break, as the time of mediating reaction beginning; When electric current is steady, as mediating material, mix, mediate the time that reaction finishes.
In technique scheme, preferably, the reaction time of mediating by timer record material.
In technique scheme, preferably, when reaction beginning is mediated in judgement, start timer timing; When reaction end is mediated in judgement, by timer, extend the time that stirring paddle of kneading machine is rotated further of controlling, the different situations of mediating according to material are set to mediate to react and are finished the time that rear continuation is mediated.
In technique scheme, preferably, use timer to control stirring paddle of kneading machine and rotate; When timer record, paddle is all the time in rotary state; When timer stops meter record, paddle also stops operating.
In technique scheme, preferably, described timer is connected with timing relay.
In technique scheme, preferably, described timer has reset and pause function; When kneading process need to be interrupted processing, timer automatically locks the time, time out; After kneading operation completes, timer bit recovery original state continues next operation.
When the inventive method is mediated material, the momentary current of stirring paddle of kneading machine carries out sample record, and when mediating reaction beginning, electric current can be undergone mutation, and mediates the start time of reaction according to current break situation automatic decision.When mediating reaction end, electric current can tend to be steady, and mediates the end time of reaction according to the stability state automatic decision of current value.
When reaction beginning is mediated in judgement, the timing of startup timer, continues timing when mediating when reaction finishes, and can mediate reaction according to the different situations setting of material kneading and finish the time that rear continuation is mediated, finally definite time of having mediated.
The inventive method is used timer to control stirring paddle of kneading machine and is rotated, and when timer record, paddle is all the time in rotary state, and when timer stops meter record, paddle also stops operating.Disturbing signal in order to prevent that extraneous factor from producing, is provided with a timing relay with false action-proof, surpasses the signal of certain hour pulse width as a useful signal, is used for triggering timing device.The timer of selecting has reset and pause function.When needs timer when kneading process is interrupted processing automatically locks the time, time out.After kneading operation completes, the timer continuation next operation that restPoses that can reset.
The inventive method is according to the situation of carrying out of paddle electric current automatic decision material kneading operation, reduced the error of artificial judgment, reduce material and mediated underproof situation, reduced by 30% manual operation, reduced labour intensity, improve 10% production efficiency, in the time of can being widely used in material to use kneader wet mixing operation, in the obvious commercial production of curent change, obtained good technique effect.
Below by embodiment, the present invention is further elaborated.
Embodiment
[embodiment 1]
During production pyrolysis gasoline hydrogenation catalyst carrier, the momentary current of stirring paddle of kneading machine is carried out to sample record.When current break, as the time of mediating reaction beginning; When electric current is steady, as the time of mediating reaction end.The wet process of pinching of material is constant in 45 ± 5 minutes, during only need to suspend No. 1 kneader and shovel material operation,, there is the defective situation of doing over again of kneading in the catalyst support steady quality of production.
[comparative example 1]
During production pyrolysis gasoline hydrogenation catalyst carrier, by artificial judgment, mediate situation, wet and pinch process control at 45 ± 10 minutes, need during this time to suspend No. 3 kneaders and observe material kneading situation, and carry out moisturizing and shovel material operation, the carrier quality fluctuation of producing is larger, has 10% defective needs of kneading to do over again and again mediates.
