Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a desiccant tube for a portable chromatograph, which can be quickly replaced, according to the following technical scheme: a fast replaceable drying agent tube for a portable chromatograph comprises a tube body 1 with an opening at the upper end and two pagoda joints 11 arranged at the lower end of the tube body 1, wherein the two pagoda joints 11 are symmetrical about the axis of the tube body 1. The tube body 1 and the pagoda joint 11 adopt standard components and can be directly connected with a gas tube of a chromatograph.

Still including the baffle 2 along the axis in the body 1 that sets up, and baffle 2 cut apart into two dry chambeies that correspond with pagoda joint 11 with body 1, the upper end of body 1 is connected with the lid mechanism that supports tight baffle 2, and the upside of baffle 2 is provided with the backward flow hole 21 that connects into the backward flow chamber of "U" type with two dry chambeies, is provided with drying mechanism in the dry intracavity. The drying mechanism comprises semicircular filter plates 22 with filter holes which are fixed on the partition plate 2 at equal intervals, and granular drying agents 23 are arranged between the upper filter plate 22 and the lower filter plate 22. The filter plate 22 is attached to the inner wall of the tube body 1, and the drying agent 23 is spherical and has a gap between the two, thereby facilitating air circulation.

The cover mechanism comprises a cover body 12 connected to the upper end of the pipe body 1, and a sealing gasket 13 is arranged in the cover body 12. The drying agent is convenient to open and replace. The cover 12 is screwed to the pipe 1. The opening is convenient. Baffle 2 can be taken out from top to bottom along body 1, and the lower extreme of baffle 2 is fixed with two reference columns 24, and two reference columns 24 are symmetrical about the axis of body 1, and the bottom of body 1 set up with reference column 24's constant head tank, lid 12 supports the upper end of tight baffle 2. So that the partition 2 facilitates removal and replacement of the drying agent 23.

The working principle is as follows: during the use, connect the pagoda joint 11 on the body 1 directly to insert on the chromatograph, a pagoda joint 11 admits air, another gives vent to anger, gas enters into body 1 back, through baffle 2 upflow, by the drying agent 23 drying, then reach body 1 top, the backward flow hole 21 on the baffle 2 enters into another dry chamber, finally flows out from another pagoda joint 11, just so realized "U" type is dry, dry area is bigger, the effect is better, here direct plug body 1, realize changing, it is more convenient.
