Description
Technical field
The present invention relates to a kind of liquid level sensor, specifically refer to a kind of liquid level sensor for etching solution recycling system.
Background technology
Liquid level sensor is as a kind of Hall element of measuring liquid level, according to the principle of Hall element, by converting magnetic induction density to electric signal, by the floating block arranging on liquid level sensor, realized the measurement of liquid level, 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 user uses like a cork.
Present liquid level sensor adopts a whole body of rod put floating block and limit with limited block mostly, during use, allow its self-suspending at liquid internal, but when container is too small or liquid level is not high, thereby liquid level sensor can not suspend and can not complete location, meanwhile, when having vibrations or jolt, liquid container also can affect location.
Summary of the invention
Problem to be solved by this invention is to provide a kind of liquid level sensor for etching solution recycling system, has solved the problem that the liquid level sensor using in etching solution recycling system can not be adjusted arbitrarily height, can not stablize location.
Technical scheme provided by the invention is: for the liquid level sensor of etching solution recycling system, comprise the body of rod, the described body of rod is the cylindrical structural of inner hollow, its one end is induction rod, induction rod inside is provided with tongue tube, induction rod two ends are respectively equipped with back-up ring and register pin, magnetic floating block is enclosed within on induction rod, the body of rod is also provided with lower link stopper and upper block at register pin right-hand member, in the body of rod between lower link stopper and upper block, be provided with groove, body of rod one end outside upper block also has the through hole being connected with body of rod internal cavities, the sense line being electrically connected to tongue tube passes from through hole.
Described back-up ring is positioned at 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 and prevent that magnetic floating block from coming off in induction rod, simultaneously and register pin the stroke of magnetic floating block is played to restriction effect.
Described magnetic floating block adopts corrosion resistant plastic material to make, and inside is provided with magnetisable material.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 magnetic floating block causes that by the change of inner magnetisable material magnetic induction density when mobile the change of tongue tube produces electric signal, and electric signal transmission is processed after going 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 conduction simultaneously, so sense line scribbles diaphragm corrosion-resistant and insulation, to improve serviceable life and the security of sense line.
The described body of rod is also provided with external thread at the outside surface of through hole one end.When liquid level sensor internal liquid is stable not while causing magnetic floating block buoyancy to be affected, only need in position be provided with helicitic texture that a band and external thread match just the body of rod fix, can normally measure.
The invention has the advantages that: this liquid level sensor for etching solution recycling system of design of the present invention, the liquid level that not only can adapt to liquid container and the arbitrary height of any size, it can be fixed on desired position simultaneously, good stability, and practicality increases greatly.

embodiment
Embodiment 1
Referring to Fig. 1, liquid level sensor for etching solution recycling system, comprise the body of rod 6, the described body of rod 6 is the cylindrical structural of inner hollow, its 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 induction rod 3, the body of rod 6 is also provided with lower link stopper 7 and upper block 9 at register pin 5 right-hand members, in the body of rod 6 between lower link stopper 7 and upper block 9, be provided with groove 8, the body of rod 6 one end outside upper block 9 also has the through hole 10 being connected with the body of rod 6 internal cavities, the sense line 11 being electrically connected to 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 is also provided with external thread at the outside surface of through hole 10 one end.
In use, be provided with one use with etching solution that chamber is connected get liquid box, whole liquid level sensor is suspended in the etching solution of getting in liquid box, magnetic floating block 4 is deep in etching solution completely, more than 9 position of overhead gage is exposed on liquid level and does not contact with etching solution, etching solution is in use due to 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 the interior movement of induction rod 3, change due to magnetic induction density in its moving process causes the switch of tongue tube 2 movable, the movable electric signal producing of tongue tube 2 is 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, according to behaviour in service, just can add the inner ion of etching solution or stop injecting ion, by whole system, just can automatically control etching solution, .
When liquid container is too small or liquid level is lower when being not enough to place or being not enough to float sensor, can be by sensor setting in gripping mechanism, gripping mechanism is provided with the structure of mating with groove 8, sensor can be moved up and down and be adjusted suitable position by groove 8 in clamping structure, lower baffle plate 7 and overhead gage 9 not only can fixation of sensor but also movement that can limiting sensor, thereby with the too high or too low sensor failure that causes of no-sensor.
When due to outside cause, cause etching solution have fluctuation, when unstable, when being not easy to test or cannot correctly testing, only need be by sensor the external thread by its end be fixed on desired location and sensor can be fixed, practicality strengthens greatly.
Can well realize the present invention as mentioned above.
