Description
The utility model relates to a kind of enamelled vessel that stores corrosive liquids.
In the prior art, enamelled vessel can be used as the storage tank of corrosive liquids, in order to measure the liquid level of the liquid in the container, normally the sidewall of container is upper and lower respectively has a hole to communicate with the inner chamber of container, on these upper and lower two holes a vertical transparent glass tube is housed, this transparent glass tube communicates with container intracavity by two holes.By observing the indicated liquid-column height of transparent glass tube, can know the liquid level in the container.The container of this structure has following shortcoming: (1) owing to there are two holes that communicate with container intracavity, makes the complicate fabrication process of container; (2) described two holes become potential liquid leak point, and the end face out-of-flatness of glass tube in addition also causes liquid to be revealed easily, because the liquid that stores in the container is corrosive liquids, the leakage of its liquid pollutes the environment and causes personnel's damage; (3) glass tube is corroded easily, and the liquid level of demonstration is fuzzy, and the in-plant safety that examines the entail dangers to staff.(4) glass tube can be because variation of temperature and cracked; (5) up and down the determining positions in two holes the liquid level limit that can measure, also promptly exist up and down blind area, the liquid level blind area is bigger up and down usually.
The purpose of this utility model provide a kind of can be with liquid level signal teletransmission and the enamelled vessel that shows by secondary instrument.
The technical solution of the utility model is: the utility model comprises cover and tank body, and the formed internal chamber wall of cover and tank body scribbles glass-lined coating, and cover top is provided with charging aperture, and tank base is provided with discharging opening; Liquid level sensor is housed on the cover, and the probe of this liquid level sensor is arranged in the inner chamber of tank body, and the transducing signal output terminal of liquid level sensor is connected to the secondary instrument that can show liquid level by lead.Described liquid level sensor is float-ball type liquid level sensor or capacitance level transducer, and liquid level sensor will be delivered to secondary instrument by lead corresponding to the sensing electric signal of liquid level, carries out liquid level and shows.
The utility model compared with prior art has following advantage:
(1). the probe of liquid level sensor can extend in the container than the bottom, make the lower limit blind area greatly reduce, and have upper limit blind area hardly.
(2). the liquid level signal at scene can be reached the secondary instrument of the demonstration liquid level of being located at the pulpit by lead, be convenient to the staff and in time liquid level is controlled.
(3). liquid level shows accurate, directly perceived.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is the structural representation of an embodiment of the present utility model; Wherein:
1. terminal box; 2. secondary instrument; 3. cover; 4. clamp; 5. tank body; 6. float; 7. feeler; 8. discharging opening; 9. container leg; 10. charging aperture.
Accompanying drawing 2 is the structural representation of the float 6 in the accompanying drawing 1; Wherein:
11. polytetrafluorethylecoatings coatings; 12. circular hole; 13. magnet.
Accompanying drawing 3 is the circuit theory diagrams in the feeler 7 in the accompanying drawing 1; Wherein:
K1, K2, K3, K4, K5......KN are tongue tube;
R1, R2, R3, R4, R5......RN are resistance.
With reference to accompanying drawing 1, the liquid level sensor of this accompanying drawing adopts the float-ball type liquid level sensor.Described float-ball type liquid level sensor comprises feeler 7 and the float moving up and down 6 that is enclosed within on this feeler 7; Feeler 7 surfaces scribble corrosion-resistant coating, this corrosion-resistant coating can be the polytetrafluoroethylene layer, there are multistage tongue tube and resistance in its inside, the circuit diagram of tongue tube and resistance as shown in Figure 3, resistance R 1 wherein and tongue tube K1 are positioned at the top of feeler 7, resistance R N and tongue tube KN are positioned at feeler 7 bottom, and total number of its resistance can be determined according to the liquid level of container; The profile bottom of feeler 7 breaks away from feeler 7 greater than the central circular hole 12 of float 6 to prevent float 6.The surface of float 6 scribbles corrosion-resistant coating, and this corrosion-resistant coating can adopt polytetrafluoroethylene coating 11, and the structure of float 6 is seen accompanying drawing 2, and the inside of float 6 is provided with magnet 13, and Packed space, makes the proportion of float 6 less than the liquid specific gravity in the container; There is circular hole 12 in float 6 central authorities, and the diameter of this circular hole 12 is greater than the diameter of feeler 7, and making float 6 can be guide rail with feeler 7, move up and down with the variation of liquid, swim on the liquid level all the time.Tongue tube generally is a normally open, the magnetic of the magnet 13 in the float 6 can make the tongue tube closure, so, liquid level change can cause float 6 to be in the diverse location of feeler 7 in the container, thereby make the tongue tube closure of this position, make the resistance at signal output part two ends change, thereby an electric signal is delivered to secondary instrument, by secondary instrument liquid level is shown.
Liquid level sensor can also be capacitance level transducer.Level gauging for conducting liquid, liquid level sensor puts the polytetrafluoroethylene insulating sleeve by stainless steel electrode and constitutes, at this moment stainless steel bar is as an electrode, conducting liquid is as another electrode, the polytetrafluoroethylene insulating sleeve is as the filled media of centre, and this three constitutes a cylindrical capacitor; This class is more representational to be UYB-11A type capacitive liquid level sensor.For the liquid level of measuring non-electrically conductive liquid, liquid level sensor at this moment is that mutually insulated is fixed by two stainless-steel tubes, constitutes a coaxial cylindrical capacitor.When liquid level was zero, sensor two electrodes itself constituted an electric capacity, and middle dielectric is an air; When liquid level rises, filled the measured medium of the specific inductive capacity different between a part of electrode with air, its electric capacity increases, and makes changes in capacitance reflect the variation of liquid; The sensor of this class is that UYB-12A is for more representative with the model.But above-mentioned two class capacitance level transducers all are not suitable for the measurement of viscous medium liquid level.
