Abstract
The utility model provides a cooling device for a high-temperature level meter. The cooling device is characterized in that a cavity, of which one end is open and the other end is welded on a level meter connection flange, is sleeved outside a level meter detection pole; and a nitrogen connecting pipe is arranged on the side of the cavity close to the fixed end and is connected with a nitrogen pipeline. The whole cavity can be filled with blown-in nitrogen, and the detection pole of the level meter is surrounded and blown by the continuously-added nitrogen, so the cooling effect is uniform, accordingly, the cooling effect of the level meter is improved and the service life thereof is prolonged by more than one time, thereby reducing the spare part consumption and maintenance cost, avoiding output signal distortion and ensuring the measuring accuracy and the system operation. Besides, the cooling device provided by the utility model has the advantages of simple structure, convenience in application, improved nitrogen utilization ratio, and nitrogen conservation.
Description
Technical field
The utility model belongs to the automatic control device field, relates in particular to a kind of high temperature modification static capacitive level-sensing device cooling device that is used for dedusting level gauging system.
Background technology
Chemical plant cork dry quenching disposable dedusting level gauging system adopts high temperature modification static capacitive level-sensing device to carry out level gauging mostly; Because in the equipment operation process; The coke blacking temperature of surveying up to more than 1000 ℃, therefore need adopt nitrogen purge cooling in the level-sensing device outside, but because the position that purges is limited to the level-sensing device rapier; Thereby purge the inhomogeneous cooling effect that makes and to reach desirable degree; Cause the frequent scaling loss of level-sensing device rapier and insulator, not only increased nitrogen consumption, wasted resource; And shortened serviceable life of level-sensing device, and increasing spare parts consumption and maintenance cost, only have three months the serviceable life of general level-sensing device.Especially directly cause level-sensing device output spurious signal, have a strong impact on the operation operation of measurement effect and system.
Summary of the invention
The purpose of the utility model aims to provide a kind of simple in structure, can significantly improve the purging cooling effect, prolongs the level-sensing device life cycle, the high temperature modification level-sensing device cooling device of reduction expense expenditure.
For this reason, the solution taked of the utility model is:
A kind of high temperature modification level-sensing device cooling device is characterized in that, outside the level-sensing device rapier, is with a cavity, and cavity one end opening, the other end are welded on the level-sensing device joint flange, on the cavity near stiff end one side, are provided with the nitrogen connecting pipe.
Said cavity adopts steel pipe to process.
The beneficial effect of the utility model is:
Owing to outside the level-sensing device rapier, set up the purging cavity that is connected with nitrogen, the nitrogen that is blown into can be full of whole inside cavity, makes the level-sensing device rapier be in constantly additional nitrogen fully and surrounds among the purging; Cooling has evenly improved the level-sensing device cooling effect, prolongs the serviceable life of level-sensing device; Level-sensing device is prolonged more than one times serviceable life; Thereby reduce spare parts consumption and maintenance cost, avoid level-sensing device output distorted signals, guarantee the operation operation of measurement effect and system.The utility model is simple in structure, is convenient to implement, and can improves the nitrogen utilization factor, saves the nitrogen consumption.
Description of drawings
Accompanying drawing is a high temperature modification level-sensing device cooling device installment state synoptic diagram.
Among the figure: joint flange 1, level-sensing device rapier 2, cavity 3, nitrogen connecting pipe 4.
Embodiment
Visible by accompanying drawing, the utility model high temperature modification level-sensing device cooling device mainly comprises level-sensing device joint flange 1, level-sensing device rapier 2, cavity 3 and nitrogen connecting pipe 4.To be employing form than the steel pipe processing and fabricating of level-sensing device rapier 2 somewhat larger in diameter cavity 3, and the one of which end opening is so that discharge nitrogen; The other end is welded on the level-sensing device joint flange 1.Simultaneously, near cavity 3 stiff ends, have circular hole, one section nitrogen connecting pipe 4 of welding on the circular hole.When cooling purges, as long as nitrogen connecting pipe 4 is connected on the nitrogen pipeline.
