Embodiment 1

[0039] The column chromatography device proposed by the present invention is used in conjunction with a feed liquid storage tank, a heat exchanger, and a heat preservation and heating storage tank.

[0040] When washing liquid: firstly, the feed liquid is put into the heat exchanger from the feed liquid storage tank for preheating, and the feed liquid after preheating is stored in the heat preservation and heating storage tank; Port 15 and nozzle-type liquid distributor 16 enter the column chromatography device. Before feeding, the decompression port 23 in the column chromatography device should be connected to the vacuum pipeline; The redistribution of the first punching sieve plate 6 evenly passes through the macroporous resin, and the separated objects are absorbed and analyzed on the macroporous resin, and the impurities and eluents of different components move downward respectively, and flow into them through the second punching sieve plate 7. The lower head 3 flows out o...

Embodiment 2

[0045] The column chromatography device proposed by the present invention is used in conjunction with a feed liquid storage tank, a heat exchanger, and a heat preservation and heating storage tank.

[0046] When washing liquid: firstly, the feed liquid is put into the heat exchanger from the feed liquid storage tank for preheating, and the feed liquid after preheating is stored in the heat preservation and heating storage tank; Port 15 and nozzle-type liquid distributor 16 enter the column chromatography device, and the pressurization port 22 in the column chromatography device should be connected with the pressurization equipment before feeding; the feed liquid dispersed by nozzle-type liquid distributor 16 is passed through The redistribution of the first punched sieve plate 6 evenly passes through the ion resin, and the separated objects are absorbed and analyzed on the ion resin, and the impurities and eluents of different components move downward respectively, and flow dow...

Embodiment 3

[0051] The column chromatography device proposed by the present invention is used in conjunction with a feed liquid storage tank, a heat exchanger, and a heat preservation and heating storage tank.

[0052] When washing liquid: firstly, the feed liquid is put into the heat exchanger from the feed liquid storage tank for preheating, and the feed liquid after preheating is stored in the heat preservation and heating storage tank; Port 15 and nozzle-type liquid distributor 16 enter the column chromatography device. Before feeding, the decompression port 23 in the column chromatography device should be connected to the vacuum pipeline; The redistribution of the first punched sieve plate 6 evenly passes through the polyamide resin, and the separated objects are absorbed and analyzed on the polyamide resin, and the impurities and eluents of different components move downward respectively, and flow into The lower head 3 flows out of the column chromatography device through the liquid...

Abstract

The invention provides a column chromatography device with a warning function. The device solves the problem that the existing chromatography device cannot alarm when the liquid is too much or too little. The device comprises a column body, an upper end socket, a lower end socket and a liquid level alarm, wherein a filler is filled in the column body, the column body is provided with a filler inlet and a filler outlet, the upper end socket is arranged on the upper end of the column body and provided with a liquid inlet, an exhaust port and a back-flushing liquid outlet, the lower end socket is arranged at the lower end of the column body and provided with the liquid outlet, the liquid level alarm is arranged on the upper end socket, and the column body is fixedly connected with the upper end socket and the lower end socket. By arranging the liquid level alarm, the column chromatography device with the warning function provided by the invention is capable of providing the warning function when the liquid is too much or too little under the unwatched state, and the device is reasonable in structure, convenient to operate, low in equipment cost, and suitable for commercial popularization and application.

Description

technical field [0001] The invention relates to a purification separation chromatography device used in the fields of pharmacy, food, chemical industry and the like, in particular to a column chromatography device with an alarm function. Background technique [0002] As one of the efficient purification and separation methods, column chromatography has been widely used in the purification and separation of natural products and synthetic products. Patent 200520050126.6 proposes a thermal insulation rapid column chromatography separator, which uses circulating water at a certain temperature for thermal insulation, which improves the separation effect of the mixture; Condenser tubes, chromatographic columns, reaction vessels, and heating devices are all connected by ground joints. The closed working environment not only reduces solvent loss but also avoids environmental pollution. However, the existing column chromatography device does not have a liquid level alarm function, a...
