Description
Technical field
The utility model relates to a kind of liquid level sensor, specifically refers to a kind of liquid level sensor for the etching solution recycling system.
Background technology
Liquid level sensor is as a kind of Hall element of measuring liquid level, principle according to Hall element, by converting magnetic induction density to electric signal, realize the measurement of liquid level by the floating block that arranges on the liquid level sensor, liquid level sensor has been widely used in the level gauging of the various media of the systems such as petrochemical complex, metallurgy, electric power, pharmacy, water supply and sewage, environmental protection and industry at present.Exquisite structure, simple adjustment and flexibly mounting means provide great convenience for the user uses like a cork.
Present liquid level sensor mostly adopts the body of rod of an integral body to put floating block and limits with limited block, allow its self-suspending at liquid internal during use, when but too small or liquid level is not high when container, thereby liquid level sensor can not suspend and can not finish location, simultaneously, when having vibrations or jolt, liquid container also can affect location.
The utility model content
Problem to be solved in the utility model provides a kind of liquid level sensor for the etching solution recycling system, has solved the problem that the liquid level sensor that uses in the etching solution recycling system can not be adjusted arbitrarily height, can not stablize location.
The technical scheme that the utility model provides is: the liquid level sensor that is used for the etching solution recycling system, comprise the body of rod, the described body of rod is the cylindrical structural of inner hollow, the one end is induction rod, induction rod inside is provided with tongue tube, the induction rod two ends are respectively equipped with back-up ring and register pin, the magnetic floating block is enclosed within on the induction rod, the body of rod also is provided with lower block and upper block at the register pin right-hand member, be provided with groove in the body of rod between lower block and the upper block, the end of the body of rod outside upper block also has the through hole that is connected with body of rod internal cavities, and the sense line that is electrically connected with tongue tube passes from through hole.
Described back-up ring is positioned at the induction rod end.The end of induction rod is the end of the body of rod, and back-up ring is same as and blocks magnetic floating block one prevent that the magnetic floating block from coming off in induction rod, simultaneously and register pin the stroke of magnetic floating block is played the restriction effect.
Described magnetic floating block adopts corrosion resistant plastic material to make, and inside is provided with magnetisable material.The magnetic floating block directly contacts with etching solution, and etching solution has certain corrosivity, magnetic floating block corrosion-vulnerable and damaging, thus cause location inaccurate, so adopt corrosion resistant plastic material to increase magnetic floating block serviceable life.Thereby the magnetic floating block causes that by the change of magnetisable material magnetic induction density when mobile of inside the change of tongue tube produces electric signal, processes after electric signal transmission is gone out again.
Described magnetisable material is magnet.
Described sense line scribbles diaphragm corrosion-resistant and insulation.Sense line contacts with the intrasystem etching solution of etching solution recycling sometimes, because etching solution has certain corrosivity, avoids simultaneously conduction, so sense line scribbles diaphragm corrosion-resistant and insulation, to improve serviceable life and the security of sense line.
The described body of rod also is provided with external thread at the outside surface of through hole one end.When the liquid level sensor internal liquid is stable not when causing magnetic floating block buoyancy to be affected, only need in position be provided with helicitic texture that a band and external thread be complementary just the body of rod fix, can normally measure.
The utility model has the advantage of: this liquid level sensor for the etching solution recycling system of design of the present utility model, the liquid level that not only can adapt to liquid container and the arbitrary height of any size, it can be fixed on the desired position simultaneously, good stability, and practicality increases greatly.

Label among the figure is expressed as respectively: 1, back-up ring; 2, tongue tube; 3, induction rod; 4, magnetic floating block; 5, register pin; 6, the body of rod; 7, lower block; 8, groove; 9, upper block; 10, through hole; 11, sense line.
Embodiment
Embodiment 1
Referring to Fig. 1, the liquid level sensor that is used for the etching solution recycling system, comprise the body of rod 6, the described body of rod 6 is the cylindrical structural of inner hollow, the one end is induction rod 3, induction rod 3 inside are provided with tongue tube 2, induction rod 3 two ends are respectively equipped with back-up ring 1 and register pin 5, magnetic floating block 4 is enclosed within on the induction rod 3, the body of rod 6 register pin 5 right-hand members also interlude be provided with lower block 7 and upper block 9, be provided with groove 8 in the body of rod 6 between lower block 7 and the upper block 9, the end of the body of rod 6 outside upper block 9 also has the through hole 10 that is connected with the body of rod 6 internal cavities, and the sense line 11 that is electrically connected with tongue tube 2 passes from through hole 10.
Above-mentioned back-up ring 1 is positioned at induction rod 3 ends.
Above-mentioned magnetic floating block 4 adopts corrosion resistant plastic material to make, and inside is provided with magnetisable material.
Magnetisable material described above is magnet.
Above-mentioned sense line 11 scribbles diaphragm corrosion-resistant and insulation.
The above-mentioned body of rod 6 also is provided with external thread at the outside surface of through hole 10 1 ends.
In use, be provided with one and get the liquid box with etching solution uses that the chamber is connected, whole liquid level sensor is suspended in the etching solution of getting in the liquid box, magnetic floating block 4 is deep in the etching solution fully, the position of overhead gage more than 9 is exposed on the liquid level and do not contact with etching solution, etching solution is in use because minimizing or the increase of ion, its density also reduces, the buoyancy that magnetic floating block 4 is subject in etching solution changes, thereby in induction rod 3 interior movements, change owing to magnetic induction density in its moving process causes the switch of tongue tube 2 movable, the tongue tube 2 movable electric signal that produce are transferred to external control system by sense line 11, the density value that shows etching solution inside according to the conversion of control system, thereby the ion concentration that can judge etching solution inside changes, just can add the inner ion of etching solution or stop ion according to behaviour in service, just can automatically control etching solution by whole system.
Too small or liquid level is low when liquid container is not enough to place or when being not enough to float sensor, can be with sensor setting in gripping mechanism, gripping mechanism is provided with the structure with groove 8 couplings, sensor can move up and down in clamping structure by groove 8 and adjust suitable position, but lower baffle plate 7 and overhead gage 9 be fixation of sensor but also movement that can limiting sensor not only, thereby with the too high or too low sensor failure that causes of no-sensor.
When causing etching solution that fluctuation is arranged owing to outside cause, when unstable, be not easy to test or can't correctly test the time, only needing that the external thread of sensor by its end is fixed on desired location can fix sensor, and practicality strengthens greatly.
Can well realize the utility model as mentioned above.
