[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0023] Example 1, reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a resin exchange column for easily replacing resin. When the resin inside the empty cylinder 100 fails, the internal resin can be replaced without disassembling the empty cylinder 100, which can improve the work efficiency of personnel and reduce the labor intensity of personnel.

[0024] Specifically, the empty cylinder 100 is hollow, and both ends of the empty cylinder 100 are integrally formed with openings, wherein a discharge member 101 is provided on the bottom opening of the empty cylinder 100; and a feed assembly 200 is provided on the top opening of the empty cylinder 100; and a connection assembly 300 is provided outside the empty cylinder 100 for fixing the empty cylinder 100. The empty cylinder 100 is an exchange column, and the empty cylinder 100 is made of amorphous inorganic non-metallic material. The transparent structure of the empty cylinder 100 is conducive to the user to more intuitively observe and judge whether the resin is really invalid.

[0025] The discharge member 101 includes a discharge tray 101a detachably connected to the empty barrel 100, and a discharge pipe 101a-1 and a first sampling pipe 101a-2 are respectively arranged on the discharge tray 101a. The discharge tray 101a is detachably connected to the empty barrel 100 by threading.

[0026] The first piston valve is provided on the discharge pipe 101a-1 and the first sampling pipe 101a-2. The feed assembly 200 includes a feed tray 201 detachably connected to the empty barrel 100, and a connecting pipe 201a is provided at the end of the feed tray 201. When judging whether the resin is truly ineffective, the color of the resin can be observed through the transparent empty barrel 100.

[0027] In summary, when replacing the resin in the empty cylinder 100, open the discharge pipe 101a-1 and the first sampling pipe 101a-2 connected to the bottom of the empty cylinder 100 to drain the resin inside the empty cylinder 100. When the injection of new resin is completed, close the discharge pipe 101a-1 and the first sampling pipe 101a-2, and pour the resin from the feeding assembly 200 until the instrument is restored to normal use.

[0028] Example 2, reference Figures 1 to 3 , which is the second embodiment of the present invention, is different from the previous embodiment.

[0029] Specifically, the feed plate 201 is provided with a feed pipe 203 and a second sampling pipe 202 at one end away from the connecting pipe 201a, and the outer walls of the feed pipe 203 and the second sampling pipe 202 are both provided with a second piston valve 202a, the outer wall of the connecting pipe 201a is provided with an external thread groove 201a-1, and the inner wall of the empty cylinder 100 is provided with an internal thread groove that is threadably matched with the external thread groove 201a-1. The matching of the external thread groove 201a-1 and the internal thread groove will realize the disassembly of the feed assembly 200.

[0030] Example 3, reference Figures 1 to 3 , which is the third embodiment of the present invention, is different from the previous embodiment.

[0031] Specifically, the connection assembly 300 includes a connection frame 301 and a first fastening clamp 301a and a second fastening clamp 301b hinged at both ends of the connection frame 301. The connection assembly 300 is used to fix the empty cylinder 100 on the iron frame. Both the first fastening clamp 301a and the second fastening clamp 301b can rotate.

[0032] The inner walls of the first fastening clamp 301a and the second fastening clamp 301b are both provided with a rubber ring 301a-1, and the first fastening clamp 301a and the second fastening clamp 301b are both integrally formed with a fixing block 301a-2 at one end away from the connecting frame 301. When the connecting assembly 300 is sleeved on the outside of the empty cylinder 100, when the two fixing blocks 301a-2 are in contact, the first fastening clamp 301a and the second fastening clamp 301b can clamp the empty cylinder 100.

[0033] The outer walls of the two fixed blocks 301a-2 are penetrated with connecting passages 301a-3, and a ball head 302a is connected to one of the fixed blocks 301a-2 via a rotating shaft, and the outer wall of the ball head 302a is connected to an insertion rod 302. The insertion rod 302 penetrates the other fixed block 301a-2 and is provided with a limit block 302b.

[0034] At this time, after rotating the ball head 302a so that the insertion rod 302 enters another fixing block 301a-2, the rotating limit block 302b can fix the rotation angle of the first fastening clamp 301a and the second fastening clamp 301b, thereby completing the fixation of the empty cylinder 100.
