In the system, an alkali distribution pump is arranged on one side of an alkali distribution tank; a water adding pipe is arranged at the upper part of the alkali distribution tank; the other side of the alkali distribution tank is connected with a feed port of a metering pump; a discharge port of the metering pump is connected with a starch milk distribution tank through a discharge pipe; a pH detection electrode is arranged on a return pipe; the pH detection electrode, a pH detection transmitter and a self-control adjuster are connected with the metering pump through signal wires; the starch milk distribution tank is connected with a distribution pump through a distribution tank outlet pipe; and the other end of the distribution pump is connected with the return pipe. In the utility model, through signal interlocking among the adjuster, the metering pump and the pH online detector, the system realizes online detection and timely automatic adjustment of the pH value, ensures stability of the pH value and further ensures the stability of liquefaction quality, shortens the pH adjustment time and reduces the adjustment offset. The online adjusting and monitoring system for the pH value of the starch milk has the advantages of high automation degree, safety, reliability and the like, and is convenient to operate.
Description
Technical field
A kind of equipment that relates to the preceding wheaten starch breast of steam ejection liquefaction adjustment pH value of the utility model.
Background technology
At present, in the production of wheaten starch sugar, owing to contain higher nutriments such as albumen in the wheaten starch; Make the very easily corrupt at short notice souring of wheaten starch breast, temperature is high more, and corruption is fast more; This stablize pH value and has brought great difficulty for wheaten starch sugaring steam ejection liquefaction adds before the enzyme preparation adjustment, and tradition adjustment pH value is adjusted does not have special-purpose regulation device, and batch (-type) is adjusted manually; Earlier material hand sampling in the material-compound tank is recorded the pH value, then according to the soda ash liquid for preparing being added in the jar, after mixing according to experience; Survey again, transfer again.Its drawback is: 1, manual work is repeatedly adjusted, and is consuming time, troublesome poeration; 2, because batch (-type) adjustment, wheaten starch becomes sour soon, in adjusted half an hour to one hour, the decline of pH value comparatively fast, instability has had a strong impact on the vigor of Ye Huamei, the quality instability causes liquefying.
Summary of the invention
The purpose of the utility model provides the online adjustment supervisory system of a kind of starch milk pH value, does not have special-purpose regulation device to solve prior art, and batch (-type) adjustment manually is consuming time, and troublesome poeration influence the vigor of Ye Huamei, problems such as the quality that liquefies instability.
The utility model mainly is made up of pH value measuring equipment and material-compound tank; Solving the technical scheme that its technical matters adopts is that alkali pump is joined in alkali-prepared tank one side setting; Alkali-prepared tank top is provided with filler pipe, and priming valve is set on the filler pipe, and the alkali-prepared tank opposite side connects the charging aperture of volume pump; The discharging opening of volume pump connects the starch milk material-compound tank through discharge nozzle, and the pH detecting electrode is set on recirculatory pipe; PH detecting electrode, pH detect transmitter, the automatic control adjusting apparatus connects volume pump through signal wire, and the starch milk material-compound tank goes out pipe through material-compound tank and connects dosing pump, and the dosing pump other end connects recirculatory pipe.
It is chain through the signal between adjusting apparatus, volume pump and the pH on-line detector adopting the good effect of the utility model, has realized the online detection of pH, timely adjustment automatically; Guaranteed the stable of pH value, and then the liquefaction quality that guarantees is stable, this automation degree of equipment is high; Be convenient to operation; Safety, reliable had both shortened the time of adjusting pH, had reduced the adjustment deviation again.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the utility model structural representation;
1 joins alkali pump, 2 alkali-prepared tanks, 3 priming valves, 4 filler pipes, 5 volume pumps, 6 signal wires, 7 automatic control adjusting apparatus, 8 pH and detects transmitter, 9 pH detecting electrodes, 10 recirculatory pipes, 11 dosing pumps, 12 material-compound tanks and go out pipe, 13 starch milk material-compound tanks, 14 discharge nozzles among the figure.
Embodiment
As shown in the figure: alkali pump 1 is joined in alkali-prepared tank 2 one side settings; Alkali-prepared tank 2 tops are provided with filler pipe 4; Priming valve 3 is set on the filler pipe 4, and alkali-prepared tank 2 opposite sides connect the charging aperture of volume pump 5, and the discharging opening of volume pump 5 connects starch milk material-compound tank 13 through discharge nozzle 14; PH detecting electrode 9 is set on recirculatory pipe 10; PH detecting electrode 9, pH detect transmitter 8, automatic control adjusting apparatus 7, connect volume pump 5 through signal wire 6, and starch milk material-compound tank 13 goes out pipe 12 through material-compound tank and connects dosing pump 11, and dosing pump 11 other ends connect recirculatory pipe 10.
Automatic control adjusting apparatus, pH detect transmitter, the pH detector electrode structure is identical with prior art.
Add 2 cubes water toward alkali-prepared tank earlier before this system uses, pour dietary alkali then into, startup is joined alkali pump and is returned stream, backflow limit, limit Jia Shui, and the alkali lye that dietary alkali is deployed into 5%-8% is subsequent use.During work; Proofread and correct the pH detecting electrode with damping fluid earlier; The pH value (5.6) that input need be adjusted on the automatic control adjusting apparatus then starts dosing pump and volume pump in succession, and the pH detecting electrode records the pH value of starch milk from recirculatory pipe; Then signal is transferred to transmitter; Transmitter is that the current signal (current signals that different pH values is corresponding different) of 4-20ma flows to the automatic control adjusting apparatus with the signal transition that obtains, and adjusting apparatus is regulated output 4-20ma electric current according to the pH value current corresponding of setting through PID and given volume pump, and the frequency of change volume pump changes the purpose that adds alkali number and then reach the newborn pH value of online adjustment inhibited starch.
This system needs to clean the pH detecting electrode, at this moment closing volume valve and volume pump after using some cycles; The pH detecting electrode is taken out, clean up, proofread and correct the pH detecting electrode with the pH damping fluid again with clear water; Again install then, open reverse flow valve again and volume pump gets final product.
