Embodiment Construction

[0012] The specific content of the present invention will be described in detail in conjunction with the accompanying drawings. A separatory funnel used in the extraction process, comprising a bottle body 1, a bottle mouth 2 arranged on the top of the bottle body 1 and a liquid outlet pipe 3 arranged at the bottom of the bottle body 1, a bottle stopper 4 is installed on the bottle mouth 2, The outlet pipe 3 is provided with a cock cavity 5, and the cock cavity 5 is equipped with a polytetrafluoroethylene cock 6, and the inside of the bottle body 1 is 2 / 5 from the bottom end of the bottle mouth 2 and 1 / 2 from the bottom end of the bottle mouth 2 A plurality of glass bases 7 are evenly distributed at each place, and a hollow demulsification rod 8 with holes is arranged in the glass bases 7. The number of the upper and lower layers of glass bases 7 inside the bottle body 1 is three, and The upper and lower layers of glass bases 7 are distributed alternately. The length of the upp...

Abstract

The invention discloses a separating funnel used in the extraction process, and belongs to the technical field of experimental vessels. According to the technical scheme, the separating funnel used in the extraction process is characterized in that the separating funnel comprises a bottle body, a bottle opening formed in neck of the bottle body and a drainpipe arranged at the bottom of the bottle body; a bottle stopper is installed on the bottle opening, the drainpipe is provided with a plug cock cavity, a polytef plug cock is installed in the plug cock cavity, multiple glass bases are evenly distributed on the portions, two-fifths away from the bottom end of the bottle opening, inside the bottle body and on the portions, one-second away from the bottom end of the bottle opening, inside the bottle body, and a hollow demulsification rod with a hole is arranged in each glass base. According to the separating funnel used in the extraction process, the structure is reasonable, the construction is simple, the liquid separation efficiency is improved, the emulsion phenomenon produced by an ordinary separating funnel in the separation process is reduced, and the problems that for the ordinary separating funnel, the flow velocity of the separating funnel is not smooth, and product loss exists under the emulsification condition are solved.

Description

technical field [0001] The invention belongs to the technical field of experimental vessels, in particular to a separating funnel used in the extraction process. Background technique [0002] In the process of chemical experiments, separatory funnels are usually used to extract, separate or purify substances. The structures of the existing separatory funnels are all similar, and generally include a spherical container, and the top and bottom of the spherical container are respectively provided with a liquid inlet and a liquid outlet communicated with the container. When using a separatory funnel for liquid separation, first turn off the switch of the funnel, then pour two incompatible liquids into the liquid inlet, mix the incompatible liquids by hand, and then let it stand The liquids with different weight ratios are naturally stratified, and then the separated liquids are obtained in sequence through the regulation of the funnel switch. However, there are some disadvanta...
