Description

A kind of assembly type ion exchange column

Technical field

The utility model belongs to ion interchange unit field, and in particular to a kind of assembly type ion exchange column.

Background technique

Ion exchange column is the switching equipment of tubing string method ion exchange, is used to loaded resin, then flows through friendship by solution The mode for changing column carrys out separation and concentration object, has a wide range of application.

Traditional ion exchange column is mostly an entirety of grinding tool casting, and material is generally quartz or plastics, to divide From different objects, the ion exchange column of different sizes or type need to be processed, cost is excessively high；In loaded resin, in resin Bubble is remained, the effect of separation and concentration object will be had an impact, it is necessary to recharge resin, it is cumbersome；Once such Ion exchange column has to be damaged at one, and whole pillar cannot use, and the service life is shorter.

Summary of the invention

In order to overcome the above deficiency, the purpose of the utility model is to provide a kind of assembly type ion exchange columns, have and are applicable in The characteristics of range is wide, low in cost, loaded resin is convenient, long service life.

The technical scheme adopted by the utility model is that:

The upper end of a kind of assembly type ion exchange column, including resin bed pipe, resin bed pipe is connected by nut, No.1 cutting ferrule There is liquid-holding pipe, the lower end of the liquid-holding pipe has and the nut, the matched connector of No.1 cutting ferrule；

It is connected with collar joint in the lower end of resin bed pipe, the collar joint is by nut, No.1 cutting ferrule and fitting body Sequence is constituted, and is connected with cored screw below the fitting body.

Further, it is additionally provided with micropore sieve plate in the lower end of resin bed pipe, outer diameter and the resin bed pipe of the micropore sieve plate Internal diameter matches, effect be make it is more uniform by the solution flow velocity of ion exchange column.

Further, No. two cutting ferrules are equipped with, between fitting body and cored screw to increase between fitting body and cored screw Leakproofness.

Further, there is screw thread outside the upper end of the liquid-holding pipe, can facilitate and be connect with other devices；Liquid-holding pipe bottom Outer diameter is equal with the internal diameter of resin bed pipe.

Further, each component material of the assembly type ion exchange column is quartz or plastics.

The utility model has the beneficial effects that

Each component of the utility model is attached using assembling mode, and replacement component is more convenient, when some parts damages When, it need to only be replaced, other component can continue to use, and extend the service life of entire exchange column on the whole；It can The resin bed pipe of replacement, not only facilitates loaded resin, but also expands the scope of application of ion exchange column.

Detailed description of the invention

Fig. 1 is that the structure of the utility model splits schematic diagram；

Fig. 2 is the assembled structural schematic diagram of the utility model；

In figure: 1- liquid-holding pipe, 2- No.1 cutting ferrule, 3- nut, 4- resin bed pipe, 5- micropore sieve plate, 6- fitting body, 7- are hollow Screw, No. bis- cutting ferrules of 8-.

Specific embodiment

With reference to the accompanying drawing, the utility model is described in detail.

As illustrated in fig. 1 and 2, a kind of assembly type ion exchange column, each component material are polytetrafluoroethylene (PTFE), including resin bed pipe 4, resin bed pipe 4 can be replaced according to the amount of resin of required filling, and the upper end of resin bed pipe 4 passes through nut 3, No.1 cutting ferrule 2 It is connected with liquid-holding pipe 1, the lower end of the liquid-holding pipe 1 has to be constructed with the nut 3, the matched fitting body of No.1 cutting ferrule 2, the Sheng Liquid pipe 1 can be according to how much customizations of required liquid amount；

It is connected with collar joint in the lower end of resin bed pipe 4, micro-mesh is equipped between collar joint and resin bed pipe 4 Plate 5, micropore sieve plate 5 make more uniform by the solution flow velocity of ion exchange column, and the collar joint is by nut 3, No.1 cutting ferrule 2 It is sequentially constituted with fitting body 6, cored screw 7 is connected with below fitting body 6, No. two are equipped between fitting body 6 and cored screw 7 Cutting ferrule 8, the cored screw 7 is for flowing out solution or connection outlet tube；Wherein, resin bed bore 4mm, outer diameter 6mm；Micropore Sieve plate diameter 4mm, thickness 1mm；The center-hole diameter 2mm of cored screw.
