Abstract
The utility model provides a technical scheme of a volumetric flask cleaner, the volumetric flask cleaner of the technical scheme comprises a closed cleaning bottle, a suction pipe with a spray nozzle is fixed on the cleaning bottle, one end of the suction pipe without the spray nozzle is close to the bottom of the cleaning bottle, the other end of the suction pipe with the spray nozzle is arranged outside the cleaning bottle, the top of the cleaning bottle is connected with a rubber ball through a pipe, both ends of the rubber ball are provided with a one-way valve respectively, and a first valve is arranged on the pipe. The cleaner provided by the technical scheme has a simple structure, and can be reused; the volumetric flask can be cleaned by potassium chromate lotion, without causing a risk.
Description
Technical field
The utility model relates to a kind of cleaning device, especially a kind of volumetric flask washer.
Background technology
In the prior art, technique known is that volumetric flask is a fine measuring instrument, and the cleanser that unavailable friction is strong etc. is scrubbed, and cause precision inaccurate with anti-friction stroke, and because of bottleneck is thin, hairbrush is difficult to get access, uses that the back is difficult to be cleaned.If clean,, be difficult for washing because the volumetric flask inner space is big and irregular with less brush head.Now many with after the immersion of potassium chromate washing lotion again water rinse well, owing to contain a large amount of concentrated sulfuric acids and the extremely strong potassium bichromate of oxidisability in the potassium chromate washing lotion, so corrosivity is extremely strong, need tape thickness layer rubber gloves to take out the back after the immersion and clean, do not splash on the skin then cause skin burn, splash and then cause the clothing corrosion on the cotton clothing in case do not note washing lotion, dangerous big, if when cleaning,, easily cause volumetric flask to break because the volumetric flask bore is little and wall is thin with the ultrasonic cleaning machine.This is the existing in prior technology weak point.
Summary of the invention
The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of technical scheme of volumetric flask washer is provided, and the cleaner structure of this scheme is simple, can use repeatedly, and can use the potassium chromate washing lotion to clean volumetric flask, does not have dangerous.
This programme is realized by following technical measures: a kind of volumetric flask washer, include airtight washer bottle, be fixed with the suction pipe that has shower nozzle in the washer bottle, an end that does not have shower nozzle of described suction pipe is near the bottom of washer bottle, the end that suction pipe has a shower nozzle is arranged on the outside of washer bottle, the top of washer bottle is communicated with a rubber ball by conduit, and the two ends of described rubber ball are provided with check valve, and described conduit is provided with first valve.The top of described washer bottle is provided with columniform cylindrical shell, and cylindrical shell is communicated with by pipeline with washer bottle, is fixed with filter screen on the pipeline, also is provided with second valve on the pipeline of cylindrical shell and washer bottle connection.Also be provided with escape pipe on the pipeline of described connection rubber ball and washer bottle, escape pipe is provided with the 3rd valve.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because the top in airtight washer bottle is communicated with a rubber ball by conduit in this scheme, the two ends of described rubber ball are provided with check valve, can in washer bottle, clamp-on air by the extruding rubber ball, and prevent that air from spilling from washer bottle; Washer bottle is provided with suction pipe, suction pipe one end is near the washer bottle bottom, the other end has shower nozzle, be arranged on the washer bottle outside, in the time of the extruding rubber ball, it is big that the washer bottle inner air pressure becomes, liquid is under action of air pressure in the washer bottle, from the shower nozzle ejection, volumetric flask tips upside down on the shower nozzle, so can directly clean volumetric flask from the cleaning fluid of shower nozzle ejection; The top of washer bottle is provided with columniform cylindrical shell, cylindrical shell is communicated with by pipeline with washer bottle, be fixed with filter screen on the pipeline, on the pipeline that cylindrical shell and washer bottle are communicated with, also be provided with second valve, cleaned volumetric flask from the cleaning fluid of shower nozzle ejection after, can in cylindrical tube, compile, after cleaning end, open second valve, cleaning fluid will flow in the washer bottle, in order to using next time, screen pack can elimination impurity; In addition, on the pipeline that is communicated with rubber ball and washer bottle, also be provided with inlet opening, be provided with the 3rd valve, can in washer bottle, add cleaning fluid at the inlet opening place, add cleaning fluid after, with the 3rd valve closing, keep the washer bottle sealing.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1 is washer bottle, and 2 is suction pipe, and 3 is shower nozzle, and 4 is rubber ball, and 5 is check valve, and 6 is first valve, and 7 is cylindrical shell, and 8 is escape pipe, and 9 is second valve, and 10 is the 3rd valve, and 11 is filter screen.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the volumetric flask washer of this programme, include airtight washer bottle 1, be fixed with the suction pipe 2 that has shower nozzle 3 in the washer bottle 1, an end that does not have shower nozzle 3 of described suction pipe 2 is near the bottom of washer bottle 1, and the end that suction pipe 2 has a shower nozzle 3 is arranged on the outside of washer bottle 1, and the top of washer bottle 1 is communicated with a rubber ball 4 by conduit, the two ends of described rubber ball 4 are provided with check valve 5, and described conduit is provided with first valve 6.The top of described washer bottle 1 is provided with columniform cylindrical shell 7, and cylindrical shell 7 and washer bottle 1 are communicated with by pipeline, are fixed with filter screen 11 on the pipeline, also is provided with second valve 9 on the pipeline that cylindrical shell 7 and washer bottle 1 are communicated with.Also be provided with escape pipe 8 on the pipeline of described connection rubber ball 4 and washer bottle 1, escape pipe 8 is provided with the 3rd valve 10.
When injecting cleaning fluid, open second valve 9 and the 3rd valve 10, first valve 6 is closed, cleaning fluid is injected from cylindrical shell 7, cleaning fluid enters in the washer bottle 1 through filter screen 11.During cleaning the capacity bottleneck is enclosed within downwards on the suction pipe 2, open first valve 6, extruding rubber ball 4, make air enter washer bottle 1 through check valve 5 is unidirectional, the bottle internal pressure increases makes washing lotion shower nozzle 3 ejections of passing through on the suction pipe 2, move up and down volumetric flask, make the volumetric flask inwall evenly spray washing lotion, the washing lotion that flows down on the volumetric flask inwall temporarily is stored in cylindrical shell 7 bottoms, repeat above step two to three time Deng the washing lotion of volumetric flask inwall more after a little while, close first valve 6, open second valve 9 and the 3rd valve 10,, close second valve 9 and the 3rd valve 10 putting into washer bottle 1 after the washing lotion filtration that is temporarily stored in the cylindrical shell, take off volumetric flask and rinse well, finish cleaning process with clear water and purified water.
