Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Example (b):

a glass condenser, referring to fig. 1 and fig. 2, comprises a glass main body 1, wherein the outer side wall of the glass main body 1 is respectively provided with a glass nozzle inlet 15, a glass nozzle outlet 16 and a vacuum nozzle 14, and the glass main body 1 is internally provided with an outer ring snake-shaped glass coil pipe 21 and an inner ring snake-shaped glass coil pipe 22; the glass nozzle inlet 15 is connected with the lower end opening of the inner ring snake-shaped glass coil pipe 22, the inner ring snake-shaped glass coil pipe 22 spirals clockwise, the upper end opening of the inner ring snake-shaped glass coil pipe is connected with the upper end opening of the outer ring snake-shaped glass coil pipe 21, the outer ring snake-shaped glass coil pipe 21 spirals anticlockwise and downwards, and the lower end opening of the outer ring snake-shaped glass coil pipe is connected with the glass nozzle outlet 16, so that.

Referring to fig. 2, a liquid inlet pipe 11 and a liquid return pipe 12 are respectively arranged on the side wall of the glass body 1, and the bottom wall of the glass body is provided with a liquid outlet pipe 13; be provided with water conservancy diversion piece 3 in the glass main part 1, water conservancy diversion piece 3 can make the solvent lime set can not flow into in the liquid return pipe 12 along glass main part 1 inside wall.

Referring to fig. 2, the outer circumferential side wall of the baffle 3 is connected with the inner side wall of the glass main body 1, and the baffle 3 is made of glass and is integrally formed with the glass main body 1; a funnel-shaped opening is formed in the flow deflector 3, and the central axis of the opening is superposed with the central axis of the liquid discharge pipe 13; the ports of the liquid inlet pipe 11 and the liquid return pipe 12 are respectively positioned at two sides of the flow deflector 3, and the liquid return pipe 12 and the liquid discharge pipe 13 are positioned at the same side, namely the port of the liquid inlet pipe 11 is positioned above the flow deflector 3, and the ports of the liquid return pipe 12 and the liquid discharge pipe 13 are positioned below the flow deflector 3; meanwhile, the glass mouth inlet 15 and the glass mouth outlet 16 are located above the baffle 3.

Referring to fig. 2 and 3, in the present embodiment, when the glass condenser works, the feed valve 4 is disposed in the liquid inlet pipe 11, the liquid return pipe 12 is connected to the reduction box 5, the glass pipe 6 extending into the liquid return pipe 12 is disposed in the reduction box 5, the end of the glass pipe 6 is sleeved with the sample bottle 7, the reduction box 5 is disposed with a sealing membrane (not shown in the drawings) for improving the connection sealing performance, and the reduction box 5 belongs to the prior art and is irrelevant to the invention point of the present invention, so it is not explained again; a collecting bottle is sleeved on the liquid discharge pipe 13, and a hose 41 which penetrates through the upper opening of the flow deflector 3 and then extends into the glass tube 6 is arranged on the feeding valve 4.
