Abstract
The utility model relates to a papermaking fluorescent whitening agent adding device which comprises a storage barrel used for storing fluorescent whitening agents, a sealing container, a piston movably arranged in the sealing container, a liquid level sensor embedded and installed in the sealing container, an electric push rod installed on the bottom of the sealing container, an electronic control valve II, and a shower nozzle installed at the outlet end of the electronic control valve II. A single-chip microcomputer controls a piston rod of the electric push rod to move downwards to drive the piston to move downwards. Under the effect of negative pressure, the fluorescent whitening agents in the storage barrel enter the sealing container through a pipeline, and the liquid level sensor can monitor the quantity of the fluorescent whitening agents in the sealing container in real time, and feed signals back to the single-chip microcomputer. When the needed quantity is reached, the single-chip microcomputer controls the electronic control valve II to be opened and an electronic control valve I to be closed, and then the piston rod of the electric push rod extends outwards to push the piston to move upwards, so that the fluorescent whitening agents in the sealing container are pressed into the portion of the shower nozzle through the pipeline and sprayed into pulp through the shower nozzle.
Description
Technical field
The utility model relates to pulp technology for making paper, is specifically related to a kind of papermaking adjuvant adding device.
Background technology
As everyone knows, need to add fluorescent whitening agent in paper industry, mostly after manually taking according to metering, join in paper pulp in production process, but rely on the weighing precision that manually takes fluorescent whitening agent to be difficult to ensure, thereby the paper of producing is difficult to unanimously.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of paper grade (stock) fluorescent whitening agent adding set.
The utility model overcomes the technical scheme that its technical problem adopts:
This paper grade (stock) fluorescent whitening agent adding set, comprise for storing the storage vat of fluorescent whitening agent, airtight container, be movably set in the piston in airtight container, inlay the liquid level sensor be installed in airtight container, be installed on the electric pushrod of sealing container bottom, electric control valve II and be installed on the shower nozzle on the electric control valve II port of export, the piston rod of described electric pushrod is connected in the bottom of piston, the top of described airtight container utilizes pipeline to be connected with the bottom of storage vat by the electric control valve I, the arrival end of described electric control valve II is connected in the top of airtight container by pipeline, described electric control valve I, the electric control valve II, electric pushrod and liquid level sensor all are connected in single-chip microcomputer.
In order to realize closed-loop control, also comprise the flow sensor be installed between the electric control valve I port of export and shower nozzle, described flow sensor is connected in single-chip microcomputer.
For the residue fluorescent whitening agent by airtight container is delivered to storage vat, also comprise an electric control valve II, an end of described electric control valve II is connected in the top of airtight container by pipeline, and its other end is connected in storage vat by liquid back pipe.
The beneficial effects of the utility model are: thereby the piston rod of Single-chip Controlling electric pushrod moves downward driven plunger, move downward, under suction function, fluorescent whitening agent in storage vat enters into airtight container by pipeline, liquid level sensor can be monitored the amount of the fluorescent whitening agent in airtight container in real time, and by signal feedback to single-chip microcomputer, when reaching aequum, the Single-chip Controlling electric pushrod quits work.Single-chip Controlling electric control valve II is opened afterwards, and the electric control valve I is closed, and moves on the protruding promotion piston of electric pushrod piston rod afterwards, thereby the fluorescent whitening agent in airtight container is pressed into to the shower nozzle place by pipeline, and spray in paper pulp by shower nozzle.The control procedure automaticity is high, and adds the amount of fluorescent whitening agent precise and stable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is control system theory diagram of the present utility model;
In figure, 1. storage vat 2. electric control valve I 3. piston 4. electric control valve II 5. flow sensor 6. shower nozzle 7. electric pushrod 8. airtight container 9. liquid level sensor 10. electric control valve III 11. liquid back pipes.
The specific embodiment
Below in conjunction with accompanying drawing 1,2 pairs of the utility model of accompanying drawing, be described further.
This paper grade (stock) fluorescent whitening agent adding set, comprise the storage vat 1 for storing fluorescent whitening agent, airtight container 8, be movably set in the piston 3 in airtight container 8, inlay the liquid level sensor 9 be installed in airtight container 8, be installed on the electric pushrod 7 of airtight container 8 bottoms, electric control valve II 4 and be installed on the shower nozzle 6 on electric control valve II 4 ports of export, the piston rod of described electric pushrod 7 is connected in the bottom of piston 3, the top of described airtight container 8 utilizes pipeline to be connected with the bottom of storage vat 1 by the electric control valve I, the arrival end of described electric control valve II 4 is connected in the top of airtight container 8 by pipeline, described electric control valve I 2, electric control valve II 4, electric pushrod 7 and liquid level sensor 9 all are connected in single-chip microcomputer.During use, thereby the piston rod of Single-chip Controlling electric pushrod 7 moves downward driven plunger 3 and moves downward, under suction function, fluorescent whitening agent in storage vat 1 enters into airtight container 8 by pipeline, liquid level sensor 9 can be monitored the amount of the fluorescent whitening agent in airtight container 8 in real time, and by signal feedback to single-chip microcomputer, when reaching aequum, Single-chip Controlling electric pushrod 7 quits work.Single-chip Controlling electric control valve II 4 is opened afterwards, electric control valve I 2 is closed, move on the protruding promotion piston 3 of electric pushrod 7 piston rod afterwards, thereby the fluorescent whitening agent in airtight container 8 is pressed into to shower nozzle 6 places by pipeline, and spray in paper pulp by shower nozzle 6.The control procedure automaticity is high, and adds the amount of fluorescent whitening agent precise and stable.
Also comprise the flow sensor 5 be installed between electric control valve I 4 ports of export and shower nozzle 6, described flow sensor 5 is connected in single-chip microcomputer.When promoting pistons 3, electric pushrod 7 moves upward while being injected in paper pulp by the fluorescent whitening agent in airtight container 8 by shower nozzle 6, flow sensor 5 can detect the metering of the fluorescent whitening agent of injection, and variable is fed back to single-chip microcomputer, thus form closed-loop control, strengthened the accuracy of system.
