Abstract
The utility model discloses an alkalinity automatic control device, comprising a controller, an adjusting valve, an adjusting pipeline and a sensor for measuring alkalinity, wherein the adjusting valve is disposed on an input pipeline; the sensor and the adjusting valve are respectively connected to the controller electrically; while receiving a measuring signal from the sensor, the controller outputs a control signal to the adjusting valve for adjusting the aperture of the adjusting valve. In the utility model, the sensor is used for measuring alkalinity; after comparing and processing the current alkalinity and a predetermined alkalinity, the controller outputs a control signal to the adjusting valve to adjust the aperture of the adjusting valve, so as to adjust the alkalinity which is maintained in a predetermined level. In brief, the alkalinity automatic control device of the utility model can control the alkalinity automatically, precisely and stably during the production, and can realize automatic washing, therefore manpower and material sources are saved; production quality and production efficiency are improved.
Description
Technical field
The utility model relates to the device in a kind of dyeing mercerization, relates in particular to a kind ofly to be used to keep the mill solution concentration stabilize, and measures and add the alkali concn automaton of alkali automatically.
Background technology
At present, in the dyeing mercerization, the control of the concentration of alkali is manually operated in the mill solution, by manual titration's preparing process solution, in equipment running process, webbing liquid process mill solution, thus changed the concentration of alkali in the solution, just manually certain density alkali is manual to add in the mill solution preparing, and keeps the stable of alkali concn in the mill solution like this.The artificial like this method that adds alkali has instability, has human factor to cause alkali concn and technological requirement alkali concn that certain error is arranged, thereby fabric causes fabric front and back mercerization effect different in the instability of mercerising process, influences the quality of fabric.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, provides a kind of can the mill solution alkali concn changes in fabric mercerising process the time, controls the alkali concn automaton of alkali concn automatically.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of alkali concn automaton, comprise controller, variable valve, adjusting pipeline and be used to measure the sensor of alkali concn, described variable valve is installed on the input channel, sensor and variable valve are electrically connected with controller respectively, and the measuring-signal of controller receiving sensor is exported control signal simultaneously and given variable valve to regulate the aperture of variable valve.
As the further improved technical scheme of the utility model, also comprise measuring channel and be installed in sensor on the measuring channel, also be separately installed with first T-valve and second T-valve on the measuring channel on sensor both sides, the 3rd end of described first T-valve is the rinse water inlet, the 3rd end of described second T-valve is a washing outlet, and controller is electrically connected and controls the closure of first T-valve and second T-valve respectively with first T-valve and second T-valve.
The utility model is by the sensor measurement alkali concn, after by controller the alkali concn of current alkali concn and setting being compared processing, the output control signal is given the aperture of variable valve with control conciliation method, thereby regulates alkali concn, finally makes alkali concn maintain the level of setting.In a word, the utility model can automatically, accurately and stably be controlled alkali concn in process of production, also can realize automatic flushing.Therefore, save manpower and materials, improved the quality of production and production efficiency.
Below in conjunction with accompanying drawing the present invention is described in further detail.

Embodiment
Embodiment 1
Referring to Fig. 1 and Fig. 2, a kind of alkali concn automaton, comprise controller 1, variable valve 2, input channel 3 and be used to measure the sensor 4 of alkali concn that the measuring-signal of described variable valve 2 receiving sensors 4 is exported control signal simultaneously and given variable valve 2 to regulate the aperture of variable valve 2.Also comprise measuring channel 5; Sensor 4 is installed on the measuring channel, also be separately installed with first T-valve 6 and second T-valve 7 on the measuring channel 5 on sensor 4 both sides, the 3rd end of described first T-valve 6 is rinse water inlet 6-1, the 3rd end of described second T-valve 7 is washing outlet 7-1, and controller 1 is electrically connected and controls the closure of first T-valve 6 and second T-valve 7 respectively with first T-valve 6 and second T-valve 7.
When the utility model alkali concn automaton uses, the right side port of described measuring channel 5 can be connected with the outlet of ebullator 8 in the mercerizing range 10, can make like this has liquid flow to be measured in the measuring channel 5, so that 4 pairs of alkali concns of sensor are monitored in real time.Can also a solenoid valve be installed at the inlet end of input channel 3, come the unlatching of control electromagnetic valve by controller 1, the inlet end sensor installation front end filtrator 9 at sensor 4 is used to filter testing liquid.
In the present embodiment, controller 5 adopts PLC as central processing unit, first T-valve 6 and second T-valve 7 all adopt Pneumatic three-way valve, variable valve 4 adopts electronic ratio adjusting valve, sensor 4 is made up of ball float, LOAD CELLS and transmitter, measuring principle is: the difference of the buoyancy that is subjected in the solution of variable concentrations according to ball float, measure the buoyancy value by sensor, relatively obtain the concentration of the alkali of each buoyancy value correspondence again by database data, database data is just demarcated by measuring when equipment dispatches from the factory.
The course of work of the present utility model is: during work, controller is opened second T-valve automatically, closes first T-valve, makes working fluid sampling flows through sensor, to realize measurement; Controller by the PID computing, is exported the 4-20mA electric current according to the error of the measured value of concentration set point and sensor, regulates the aperture of dynamoelectric proportion valve YM, to come the flow of alkali, the concentration that caustic soda in the alkali groove is rolled in final control in the control input channel.During parking, controller is opened first T-valve automatically, closes second T-valve, makes water flow through sensor, realizes flushing automatically.
