Detailed Description
As shown in fig. 1-2, a laboratory rectification connects, including body 1, body 1 is transparent plastic pipe, and body 1 left and right ends symmetry is provided with the joint, connect including the connecting block 9 that is the cylinder form, connecting block 9 outer fringe is all seted up rather than endocentric annular 6, the bulge loop 5 of the internal rotation of annular 6 connection, bulge loop 5 fixes on body 1 inner edge, all eccentric being fixed with horizontal intubate 10 on connecting block 9, intubate 10 towards body 1 one end and connecting block 9 towards body 1 one end parallel and level, fixed sealing connection has rather than endocentric water pipe 15 on connecting block 9, water pipe 15 right-hand member and connecting block 9 towards body 1's terminal surface parallel and level, be located body 1 outside two connecting block 9 parts and pass through U-shaped pole 4 fixed connection.
Bilateral symmetry is fixed with two fixed plates 2 in the body 1, and the circumference equipartition is fixed with a plurality of liquid pipes 3 on the fixed plate 2, and liquid pipe 3 is the glass pipe, and the terminal surface parallel and level that liquid pipe 3 both ends and two fixed plates 2 carried on the back mutually is fixed with rubber pad 7 on the fixed plate 2 towards the terminal surface of connecting block 9, has seted up on the rubber pad 7 with liquid pipe 3 concentric trompil 8, rubber pad 7 and the connecting block 9 sealing contact of one side thereof, rubber pad 7 outer fringe and 1 inner edge sealing contact of body have all been seted up on the fixed plate 2 rather than concentric interior mesopore 13, have seted up on the rubber pad 7 with interior mesopore 13 concentric outer mesopore 14, the rotatory orbit process intubate 10 axle center of trompil 8.
An elastic lug 11 is fixed on the outer edge of the connecting block 9 in the pipe body 1, an arc-shaped groove 12 corresponding to the liquid pipe 3 is formed in the inner edge of the pipe body 1, and the arc-shaped groove 12 corresponds to the elastic lug 11. When one of the tubes 3 is concentric with the cannula 10, the resilient projection 11 will be located in the arc-shaped slot 12 of the tube 3 concentric with the cannula 10, thus enabling the user to easily know when the tube 3 is concentric with the cannula 10 when the tube 1 is rotated.
The utility model discloses during the use, place its slope, rotate pipe fitting 1, make one of them liquid pipe 3 concentric with intubate 10, elastic lug 11 enters into the arc wall 12 that corresponds with the concentric liquid pipe 3 of intubate 10 this moment, connect rectification pipe and collection container respectively with two intubate 10 on the two joints, connect the comdenstion water respectively with two water pipes 15 on the two joints and advance pipe and comdenstion water return, the comdenstion water enters into pipe fitting 1 inside through the water pipe 15 with the comdenstion water advances the pipe intercommunication, then the pipe fitting 15 of comdenstion water through communicating with the comdenstion water return is discharged to 1 inside comdenstion water of pipe fitting.
During rectification, the first fraction enters the liquid pipe 3 through the insertion pipe 10 communicated with the rectification pipe, the condensed water entering the pipe 1 condenses the first fraction in the liquid pipe 3, the first fraction in the liquid pipe 3 flows into the collection container after being cooled and liquefied, along with the rise of rectification temperature, when the second fraction is to be rectified, the pipe 1 is rotated, so that the other liquid pipe 3 corresponds to the insertion pipe 10, at the moment, the second fraction enters the other liquid pipe 3, the second fraction flows into the collection container after being cooled and liquefied, when different fractions are rectified, different liquid pipes 3 are selected, the mixing amount of the front and rear fractions is reduced, and the rectification effect and the rectification purity are improved.
