Detailed Description

The invention will be further explained with reference to the accompanying drawings 1-5:

a separating funnel comprises a bottle body 3 and a cock sleeve 7 communicated with the bottom of the bottle body 3, wherein a bottle plug 1 is arranged at the bottle mouth 2 of the bottle body 3, a liquid outlet pipe 4 is connected with the bottom of the cock sleeve 7, the cock sleeve 7 is in threaded connection with a cock 6, a thick discharge hole 16 and a plurality of fine discharge holes 17 distributed in a scattering shape are respectively penetrated through the two sides of the cock 6, the plurality of fine discharge holes 17 are communicated with the thick discharge hole 16, the thick discharge hole 16 is a through hole with a semicircular cross section, the extending direction of the through hole is perpendicular to the extending direction of the cock 6, a rotating prompt disc 8 is arranged at the end part of the cock 6, a blocking button 9 and a mark a11 and a mark b12 which are respectively used for reminding the positions of the thick discharge hole 16 and the plurality of the fine discharge holes 17 are arranged on the surface of the rotating prompt disc 8, a clamping block 15 is arranged on the cock sleeve 7, the clamping block 15 is arranged in a clamping groove 5, therefore, the fixed connection between the plug sleeve 7 and the position control valve 10 is realized, the position control valve 10 is provided with a mark c13 for prompting the position of the outlet of the bottle body 3, the position control valve 10 is further provided with a limit baffle 14 for limiting the rotation stroke of the stop button 9, the limit baffle 14 is fan-shaped, and the central angle of the fan-shaped is 90 degrees.

The method for separating upper and lower layers of liquid by using the utility model comprises the following steps:

when the liquid is not separated, plug sleeve 7 is rotated so that neither identifier a11 nor identifier b12 overlaps identifier c13, i.e., so that the plug valve is in the closed state. When liquid needs to be separated, the plug valve 6 is rotated to enable the mark a11 to be overlapped with the mark c13, lower-layer liquid is directly discharged from the coarse discharge hole 16, namely, the coarse discharge separation of large flow of liquid is carried out, the liquid level in the bottle body 3 continuously drops along with the coarse discharge separation, the interface of the upper-layer liquid and the lower-layer liquid also continuously drops, the plug valve 6 is rotated to enable the mark b12 to be overlapped with the mark c13, at the moment, the liquid flowing out of the bottle body 3 firstly passes through the fine discharge hole 17 and then is discharged through the coarse discharge port 12, the flow rate of the liquid is reduced, when the lower-layer liquid is quickly discharged, the plug valve 6 is rotated again to reduce the overlapping amount of the mark b12 and the mark c13, the number of the fine discharge holes 17 communicated with the outlet of the bottle body 3 is reduced, the flow rate of the fine discharge is further reduced, when the lower-layer liquid is.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
