Abstract
The utility model relates to the field of liquid level measurement, in particular to a liquid level detection device for slurry. The liquid level detection device for the slurry comprises a tubular body and a pressure transmitter, wherein one end of the tubular body is connected with the pressure transmitter, the connecting position between the tubular body and the pressure transmitter is sealed, the pressure transmitter is composed of a pressure transmitter body and a pressure sensor, the pressure sensor extends to a cavity of the tubular body, and the other end of the tubular body extends to below the liquid level of the measured slurry.
Description
Technical field
The utility model relates to the level gauging field, relates in particular to a kind of liquid level of slurry pick-up unit.
Background technology
Various slurry pools in wet method fume desulfurizing system must be installed the liquid level of slurry pick-up unit, in order to detecting the variation of measuring cell liquid level, realize the automatic control of pond liquid level by the DCS system, thereby guarantee the operation of the stability and high efficiency of desulphurization system.In prior art, liquid level of slurry pick-up unit commonly used has ultrasonic type liquid level gauge, pressure-type liquidometer, cable formula liquid level gauge etc.Because measuring cell belongs to the closed tank body, slurry temperature in tank body is higher, thereby produce a large amount of steam, the top side location that is arranged on tank body of liquid level gauge significantly becomes the gas outlet of steam, owing to contacting for a long time steam, easily cause the dewfall of your liquid level gauge wiring board, variation has occured in the performance of appliance component, can not realize measuring.The generation of tank body slurries steam makes ultrasonic type liquid level gauge generation spurious echo cause measuring inaccurate; Bottom, tank body side setting pressure formula liquid level gauge, like this, pressure place is easily stopped up, and causes measuring inaccurate, and the post personnel must rinse just can make several times with clear water to the liquid level gauge installation place measure effectively every day, have increased post personnel's workload; The tank body end face is installed cable formula liquid level gauge, in filling with, stirring machine is arranged, and causing detecting cable formula sensor, often to be stirred the machine strand disconnected, causes liquid level gauge to damage, can't detect.
Therefore, need a kind of liquid level of slurry pick-up unit that can adapt to desulphurization system slurries character of design.
The utility model content
The utility model is to solve liquid level gauge commonly used and detects unsettled problem, provide a kind of simple in structure, detect stable and the good liquid level of slurry pick-up unit of anti-interference.
In order to address the above problem, the utility model is achieved through the following technical solutions:
Liquid level of slurry pick-up unit of the present utility model, comprise a tubular body and pressure unit, one end of described tubular body is connected with pressure unit and the junction sealing, described pressure unit is comprised of pressure unit main body and pressure transducer, described pressure transducer stretches in the cavity of tubular body, and the other end of described tubular body stretches under the liquid level of the slurries of surveying.
Further, described tubular body is sleeved on flange.
Compared with prior art, the beneficial effects of the utility model are: liquid level of slurry structure of the detecting device of the present utility model is simple, install simple and easy, detect stable, anti-interference is good and long service life.
Description of drawings
Fig. 1 is the structural representation of liquid level of slurry pick-up unit of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, liquid level of slurry pick-up unit of the present utility model, comprise tubular body 1 and a pressure unit, one end of tubular body 1 is connected with pressure unit and the junction sealing, pressure unit is comprised of pressure unit main body 2 and pressure transducer 3, pressure transducer 3 stretches in the cavity of tubular body 1, and the other end of tubular body 1 stretches under the liquid level of the slurries of surveying.Liquid level of slurry structure of the detecting device of the present utility model is simple, pressure unit does not contact or slurries and the slurries steam of less contact closed tank type detection cell, and detection is stable, anti-interference is good and long service life.
The described tubular body 1 of liquid level of slurry pick-up unit of the present utility model is sleeved on flange 4, and the liquid level of slurry pick-up unit can be fixed on detection cell by flange, installs simple and easy, convenient and practical.
The principle of work of liquid level of slurry pick-up unit of the present utility model:
one end of the tubular body of liquid level of slurry pick-up unit of the present utility model is connected with pressure unit and the junction sealing, the other end stretches under the liquid level of the slurries of surveying, along with the variation that enters the slurries amount in tubular body, in tubular body, the pressure of closed gas also changes thereupon, pressure transducer is directly transferred to the pressure unit main body with the pressure parameter of experiencing, the pressure unit main body is processed the liquid level data that draws the slurries of surveying through data, because pressure unit does not contact slurries, the obstruction of having avoided the slurries sedimentation to cause, and pressure transducer contacts less with slurries steam, avoided the interference of steam to measuring, strong anti-interference performance, it is more accurate to measure, assisted preferably the desulphurization system stable and high effective operation.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
Claims (2)
1. liquid level of slurry pick-up unit, it is characterized in that: comprise a tubular body and pressure unit, one end of described tubular body is connected with pressure unit and the junction sealing, described pressure unit is comprised of pressure unit main body and pressure transducer, described pressure transducer stretches in the cavity of tubular body, and the other end of described tubular body stretches under the liquid level of the slurries of surveying.
2. liquid level of slurry pick-up unit as claimed in claim 1, it is characterized in that: described tubular body is sleeved on flange.
