Abstract
The utility model relates to a gas collecting and metering device comprising an iron frame table, a clamp, a separating funnel, a connecting tube, a water groove, a gas collecting bottle, a guide tube, a metering barrel, scales and a three-neck bottle. The separating funnel is connected with the three-neck bottle and fixed on the iron frame table through the clamp. The three-neck bottle is connected with a bottle mouth of the gas connecting bottle through a connecting tube. The gas collecting bottle is arranged in the water tank in an inverted mode. The guide tube is arranged on the water groove. The guide tube is connected with the metering barrel. The gas collecting and metering device is simple in structure and reasonable in design. A plastic bottle is adopted to contain liquid, the metering device is a vertical metering barrel, and increased liquid amount is introduced into the metering barrel through the guide tube of the water tank. Before experiment, the liquid in the water tank only needs to be guaranteed to be level to a guide tube opening, operation personnel are relaxed during experimenting and can obtain accurate numerical reading.
Description
Technical field: the utility model relates to a kind of chemical laboratory prepares the gas less than atmospheric density with drainage collection and metering device.
Background technology: at present, chemical laboratory is used for the drainage collection and measures lighter-than-air gas and usually use inverted graduated cylinder, in order to obtain more correct reading, the one, must guarantee that graduated cylinder is vertical, the 2nd, must guarantee that the graduated cylinder liquid level is equal with the reagent bottle that is filled with water, require the operator to remove to hold up graduated cylinder and constantly pay close attention to the situation of being inverted liquid level in graduated cylinder and the graduated cylinder with hand, and the gas that increases in the graduated cylinder can make its inner discharge reduction, so that graduated cylinder may cause crooked because of Action of Gravity Field, if fixing bad graduated cylinder even can topple over, cause the failure of an experiment, in experimentation, cause busy anxiety and inconvenience for the operator.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of gas collection metering device is provided, it has mainly solved chemical laboratory and has been used for the drainage collection and measures lighter-than-air gas usually with being inverted graduated cylinder, the operator removes to hold up graduated cylinder and constantly pays close attention to the situation of being inverted liquid level in graduated cylinder and the graduated cylinder with hand, causes the problems such as busy anxiety and inconvenience for the operator in experimentation.The purpose of this utility model is achieved in that a kind of gas collection metering device is made of: iron stand, clip, separatory funnel, tube connector, tank, gas bottle, conduit, graduated cylinder, scale, three-necked bottle.Separatory funnel is connected with three-necked bottle, and is fixed on the iron stand by clip, and three-necked bottle is connected with the bottleneck of gas bottle by tube connector, and gas bottle is inverted and is placed in the tank, and conduit is installed on the tank, and conduit is connected with graduated cylinder, and graduated cylinder is provided with scale.This product structure is simple, reasonable in design, it adopts the plastic bottle carrying liquid, metering device adopts upright graduated cylinder, the amount of liquid that increases flows in the graduated cylinder by the conduit of tank, only need get final product equal with conduit mouth of liquid in the assurance tank before the experiment, operating personnel are easy and convenient in experiment, and can obtain accurately reading.
