The utility model in use, the micro computer major function comprises: 1, carry out all tasks of man-machine interface; 2, according to technology preparation, the computing board appends the water yield automatically; 3, machine startup and stop after, computer opens and closes corresponding valve automatically; 4, after water tank changed water, when liquid level was low, computer was opened quick priming valve door automatically, closed after the arrival desired value; 5, the various parameters for current use have memory function, and preserve for reusing next time as program; 6, carry out closed-loop control according to the data of electronic flow-meter feedback.
Wherein, signal conversion module is mainly changed electric signal the gas control signal, carries out computer instruction, and command is arrived topworks's (operation valve etc.).
Man-machine cross section major function comprises: 1, carry out the man-machine communication; Various parameter settings; 3, show various data and various topworkies implementation status.
Specific implementation process:
The automatic watering principle has two kinds: carry out automatic watering and the online automatic watering that detects after the PID computing according to technique.
1, carry out automatic watering after the PID computing according to technique:
The pre-treatment grey cloth will float through over-cooking, oxygen floats and float again, and the calico index has following 4 kinds in a word: destarch rate, capillary effect and the pH value of whiteness, slurry.Up to the present first three kind mostly carries out in the laboratory, and they and technique have much relations, and certainly also relevant with cloth magnitude of recruitment in water-washing process, in fact technique plays decisive role.If the inappropriate words of technique, even cloth unlimited amount of makeup water that strengthens in water-washing process, destarch rate and the capillary effect of whiteness, slurry do not reach requirement yet.Technique and reasonably (the nearly all printing and dyeing mill of this point can both reach) in the situation, replenish and an amount of appends the water yield and just can reach above-mentioned four kinds of indexs, the people is for wasting energy in minimizing.If dependence manually goes the size of Open valve to control the flow of water separately, possibility 1 puts in place and can accomplish for 10 times, but 10 times just it is hard to tell later on.Because: 1, the people is not that machinery can not be done very accurately at every turn; 2, the flow of personnel factor is changed a new person and is operated also and error can occur.It is unreasonable that the automatic watering system can solve the energy dissipation such as the valve opening degree that cause because of human factor fully, and water is also in phenomenons such as streams after shutting down.
Its principle of work is after to be computer according to the indices of reasonable process carry out the PID computing, thereby analog quantity to a proportional control valve of output is controlled the flow of its open degree control water.Thereby reach the whiteness of pre-treatment, destarch rate, capillary effect and pH value and the colour fastness of dyeing and the requirement of pH value of slurry, as do not reach requirements, allow again computer carry out the PID computing until reach requirements, just fix this program, and numbering (on computers operation), access again use (seeing the following form 1) during next same kind.
As producing cotton 40X40/133X72 in certain printing and dyeing mill, grammes per square metre: 206 grams; Door 63 " be example, because of the additional water that moves back the section of boiling from the oxygen section of floating, just need not be again to having been appended water, oxygen float or again the section of floating to appending water, per minute be 25L KG.
PH value control
Adopt reliable on-line automatic detection device, according to technological requirement, set needed value, control the large of acid through signal of output after the computer PID computing to proportioning pump.
Each technique automatic watering setting table 1 dyes:
2, detect online automatic watering:
Turbidity and colourity (online muddy instrument and online chromascope) in the ultrasonic detector detection water tank are installed in water tank, and computer is controlled the flow of water again to proportioning valve according to analog quantity of prescription (setting value of different process and kind) output.
The pre-treatment workshop:
Dyeing workshop:
Simple to operation
The operative employee is according to different kinds and technique initialization parameter (example described above), and computer automatically detects online the open degree of then controlling inlet valve and controls discharge from face.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
