Description
Technical Field
The utility model belongs to a chemistry experiment instrument and technical field, in particular to agitator liquid seal device.
Background
In chemical experiments, in order to achieve better reaction effect, a stirrer is often used; because a certain gap exists between the stirrer and the bottle stopper of the reaction bottle, a small amount of reaction medium gas cannot escape through the gap in the reaction process;
the sealing method is conventionally selected from a sealing gasket, but the sealing gasket is easily worn or damaged due to the long-term rotational friction of the stirring shaft, and the escape of reaction medium gas can occur inadvertently.
For conventional and normal pressure chemical tests, it is not practical to use expensive sealing devices, which requires that a conventional sealing device with low cost and high practical value be manufactured.
Disclosure of Invention
With the aim of solving the problems, a stirrer liquid seal device is researched and manufactured, the problem that harmful gas escapes from a shaft sleeve under the normal pressure condition is solved, and the stirrer liquid seal device has the advantages of simple structure, easiness in cleaning, low manufacturing cost and high practical value.
The utility model discloses a stirrer liquid seal device, it is formed by motor tie point, rubber tube, liquid seal cup, liquid seal cover, axle sleeve, bottleneck stopper, the combination of liquid seal medium, a serial communication port, rubber tube upper end motor tie point is followed to the lower extreme, the liquid seal cover is being connected to the lower extreme, liquid seal cup inboard is the axle sleeve, liquid seal cup lower extreme is the bottle plug part, the unsettled cover of liquid seal cover is on the axle sleeve of liquid seal cup, what pour into in the liquid seal cup is the liquid seal medium.
Preferably, the technical scheme of the utility model a stirrer liquid seal device, its characterized in that, the liquid seal cover be hollow conical body or hollow semi-ellipsoid body structure, the open-ended diameter of lower extreme is axle sleeve diameter 2-3 times.
Preferably, the technical solution of the present invention is that the diameter of the upper opening of the liquid seal cup is 1.2-1.5 times the diameter of the lower opening of the liquid seal cover.
Preferably, the utility model discloses a stirrer liquid seal device of technical scheme, its characterized in that, liquid seal medium injection volume 75-90% of liquid seal cup capacity, the static liquid level of liquid seal medium keeps 5-10 mm's distance with the axle sleeve upper edge.
The utility model has the advantages of that the liquid seal device of the stirrer solves the problem of escaping harmful gas from the shaft sleeve under the normal pressure condition, and has the advantages of good liquid seal effect, simple structure, easy cleaning, low cost and high practical value.
