Description

Liquid discharge device for infrared oil detector

Technical Field

The utility model relates to a liquid recovery field, concretely relates to infrared oil level gauge is with flowing back device.

Background

The method for measuring the petroleum in the water quality sample comprises the steps of separating the petroleum in water by using tetrachloroethylene of an extraction liquid, and detecting the content of the petroleum by using an infrared spectrophotometer. The tetrachloroethylene has certain harm to the health of people, the nature of the tetrachloroethylene is unstable, and the reagent is often deteriorated in summer with high temperature, so that the analysis result deviation is caused. Compared with the traditional method, the automatic infrared oil level meter has high automation degree, the opportunity that an analyst contacts tetrachloroethylene is obviously reduced, and the post safety risk can be effectively reduced. However, if the unused tetrachloroethylene in the instrument is not completely discharged in summer, the tetrachloroethylene goes bad, so that the analysis result deviation is caused, and the pipeline of the instrument is blocked in serious cases, so that the instrument cannot normally operate. After the jam caused, the analyst must manually add the tetrachloroethylene and carry out the oil extraction to the chance that contacts the tetrachloroethylene increases, and analyst's occupational health risk increases, so need get rid of remaining tetrachloroethylene in the instrument, and a large amount of volatilizing of tetrachloroethylene can take place for traditional flowing back, makes operational environment receive serious destruction, has very big harm to healthy simultaneously.

SUMMERY OF THE UTILITY MODEL

The utility model provides an infrared survey drain for oil appearance has solved because the tetrachloroethylene can take place rotten phenomenon if not thoroughly discharged to and the health risk problem that the manual extraction of analyst brought can't be carried out in follow-up extraction operation and has in partial pipeline jam, realized discharging the storage to the tetrachloroethylene that does not finish using, prevent to cause the jam.

The utility model provides a technical problem can adopt following technical scheme to realize:

an infrared surveys liquid discharge device for oil appearance, includes:

a tee joint;

one end of the first pipe is communicated with one end of the tee joint;

the clamping part is detachably connected to the first pipe;

the plug is axially provided with a liquid inlet hole and an exhaust hole, a first pipe seat is inserted into the liquid inlet hole, a second pipe seat is inserted into the exhaust hole, and the other end of the first pipe is communicated with the first pipe seat;

and one end of the second pipe is communicated with the second pipe seat.

Further, the clamping part includes sleeve, eccentric wheel and action bars, the sleeve cover is at a tub outer periphery, the sleeve surface is opened there is the mouth that compresses tightly, the eccentric wheel inserts and compresses tightly downtheholely, and the eccentric wheel both sides respectively with compress tightly downthehole relative wall articulated, the outer periphery of eccentric wheel is fixed to action bars one end, and the action bars is located outside the sleeve.

Further, a thread groove is formed in the lower surface of the plug, and a sealing cover is connected to the thread groove in an internal thread mode.

Further, the upper surface of the sealing cover is covered with a rubber layer.

Furthermore, the other end of the second pipe is detachably connected with a connecting plate, and a magnet is fixed on the connecting plate.

The utility model has the advantages that: owing to adopted the tee bend, the fluid-discharge tube below the tetrachloroethylene container in the instrument concatenates the tee bend, in discharging into the receiving flask through pipe one, effectively solved the unable recovery of tetrachloroethylene in the instrument and taken place rotten problem, and then realized through retrieving, the tetrachloroethylene is discharged in making the instrument, creates the advantage for follow-up instrument uses.

Due to the fact that the sealing cover is adopted, the liquid discharging hole and the exhaust hole are sealed through the sealing cover, and residual gas in the first pipe is prevented from entering air.

The eccentric wheel is adopted to control the on-off of the first pipe, so that tetrachloroethylene can be prevented from flowing into all the first pipe bodies in normal use.
