Description

Technical Field

[0001] The utility model relates to the technical field of eluent, in particular to an eluent preparation device for ion chromatography. Background Art

[0002] Ion chromatography is an effective separation and analysis technology. Its separation principle is mainly that the eluent and the sample to be tested flow into the separation column filled with ion exchange resin, and the ions to be tested form different chromatographic zones and flow out of the separation column. However, in operation, the eluent must be added regularly to adjust the working properties of the electrolyte, and the operation steps are complicated. During the analysis process, the eluent needs to be used in large quantities and needs to be prepared.

[0003] A Chinese utility model patent with publication number CN220940197U discloses an automatic ion chromatography eluent generating device. Aiming at the problem that the existing manual mixing and preparation of eluent is not efficient enough, the following scheme is proposed, which includes a mixing barrel, a storage barrel is arranged at the bottom of the mixing barrel, a plurality of support rods are fixedly installed between the mixing barrel and the storage barrel, a raw material feed pipe is fixedly connected to the top of the mixing barrel, a second infusion pipe is fixedly connected to the bottom of the mixing barrel, the bottom end of the second infusion pipe is fixedly passed through the top of the storage barrel and extends into the storage barrel, and a drain pipe is fixedly connected to the bottom of the storage barrel. In the utility model, the eluent can be mixed and prepared in the mixing barrel, the mixing efficiency is high, and it is easy to use.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device stores clean water through a transparent water storage cylinder. When the staff prepares the eluent, the staff needs to inject a certain amount of clean water into the mixing barrel. At this time, the staff needs to manually control the opening and closing of the third valve to inject clean water into the mixing barrel. However, in actual operation, it is difficult to control the amount of clean water injected, and the operation is difficult. Utility Model Content

[0005] In order to solve the above problems, the utility model provides an eluent preparation device for ion chromatography.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a device for preparing eluent for ion chromatography, comprising a mixing barrel and a water storage barrel arranged on the mixing barrel, the upper surface of the mixing barrel is connected with a water inlet pipe, the water inlet pipe and the water storage barrel are connected to each other, the upper end of the water storage barrel is provided with a feed port for feeding, and the water storage barrel is provided with a closing component for closing the water inlet pipe.

[0007] By adopting the above technical solution, when the staff needs to prepare the eluent, the staff needs to inject the eluent raw material into the mixing barrel through the feed port, and inject enough clean water into the water storage barrel. Then, the staff needs to start the closing component to store a certain amount of clean water between the first baffle and the second baffle. Furthermore, the staff only needs to move the first baffle downward to move the clean water between the first baffle and the second baffle into the water storage barrel, thereby reducing the difficulty of the staff to inject clean water in a certain amount.

[0008] Furthermore, the closing assembly includes a first baffle and a second baffle slidably disposed in the water inlet pipe, a connecting rod installed together on the first baffle and the second baffle, and a driving rod installed on the upper surface of the first baffle, and the upper end of the driving rod extends outside the water storage barrel and is slidably connected.

[0009] By adopting the above technical solution, when the staff needs to inject a certain amount of clean water into the mixing barrel, the staff needs to move the driving rod upwards, so that the connecting rod and the first baffle plate can move upwards, thereby moving the first baffle plate into the water storage barrel, and then moving the clean water in the water storage barrel into the water inlet pipe. Subsequently, when the space between the second baffle plate and the water storage barrel is full of clean water, the staff only needs to move the driving rod downwards to return the first baffle plate to the water inlet pipe. At this time, the space between the first baffle plate and the second baffle plate is full of clean water, and as the second baffle plate moves, the second baffle plate moves into the mixing barrel, and then the clean water between the first baffle plate and the second baffle plate moves into the mixing barrel, thereby reducing the difficulty for the staff to inject a certain amount of clean water into the mixing barrel.

[0010] Furthermore, a limiting block for blocking the driving rod is fixed on the upper surface of the driving rod.

[0011] By adopting the above technical solution, the probability of the driving rod moving completely into the storage barrel is reduced, thereby improving the user experience of the staff.

[0012] Furthermore, a first fixing plate is provided on the inner wall of the water inlet pipe, and a second fixing plate is fixed on the side wall of the driving rod.

[0013] By adopting the above technical solution, when the staff moves the driving rod upward, the first fixing plate blocks the second fixing plate, thereby reducing the difficulty for the staff to judge the distance the driving rod needs to move, and reducing the probability of the first fixing plate moving into the mixing barrel, thereby improving the staff's user experience.

[0014] Furthermore, a rotating groove is provided on the side wall of the water storage barrel, a rotating rod is rotatably arranged in the rotating groove, and an hourglass is connected to the rotating rod.

[0015] By adopting the above technical solution, when the staff moves the first fixing plate into the water storage bucket, the staff needs to keep the driving rod stable and rotate the hourglass. When the sand in the hourglass stops moving, the space between the first baffle and the second baffle is filled with clean water, thereby reducing the difficulty of operation for the staff.

[0016] Furthermore, two first magnet blocks are symmetrically embedded on the side wall of the rotating rod, and a second magnet block that is mutually attracted to the first magnet blocks is embedded on the inner wall of the rotating groove.

[0017] By adopting the above technical solution, when the hourglasses are perpendicular to each other, one of the first magnet blocks and the second magnet block are attracted to each other, thereby improving the stability of the rotating rod and the hourglass, thereby improving the user experience of the device.

[0018] Furthermore, a placement groove is provided on the side wall of the limit block to reduce the difficulty of workers moving the limit block.

[0019] Furthermore, sealing gaskets are provided on the side walls of the first baffle plate and the second baffle plate.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff needs to prepare the eluent, the staff needs to inject the eluent raw material into the mixing barrel through the feed port, and inject enough clean water into the water storage barrel. Then, the staff needs to start the closing component to store a certain amount of clean water between the first baffle and the second baffle. Furthermore, the staff only needs to move the first baffle downward to move the clean water between the first baffle and the second baffle into the water storage barrel, thereby reducing the difficulty of the staff to inject clean water in a certain amount;

[0022] 2. In the present application, when the staff needs to inject a certain amount of clean water into the mixing barrel, the staff needs to move the driving rod upwards to move the connecting rod and the first baffle upwards, thereby moving the first baffle into the water storage barrel, and then moving the clean water in the water storage barrel into the water inlet pipe. Subsequently, when the space between the second baffle and the water storage barrel is filled with clean water, the staff only needs to move the driving rod downwards to return the first baffle to the water inlet pipe. At this time, the space between the first baffle and the second baffle is filled with clean water, and as the second baffle moves, the second baffle moves into the mixing barrel, thereby moving the clean water between the first baffle and the second baffle into the mixing barrel, thereby reducing the difficulty for the staff to inject a certain amount of clean water into the mixing barrel;

[0023] 3. In the present application, when the staff moves the driving rod upward, the first fixing plate blocks the second fixing plate, thereby reducing the difficulty for the staff to judge the distance the driving rod needs to move, and reducing the probability of the first fixing plate moving into the mixing barrel, thereby improving the staff's user experience.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0029] like Figure 1-3 As shown, the embodiment of the present application discloses a device for preparing eluent for ion chromatography, comprising a mixing barrel 1, a water storage barrel 11, a water inlet pipe 2, a feed port 21, a closing assembly 3, a stopper 4, a first fixing plate 41, a second fixing plate 5, a rotating rod 6, an hourglass 61, a first magnet block 7, and a second magnet block 71. The water storage barrel 11 is arranged on the mixing barrel 1 for storing clean water. The water inlet pipe 2 is a circular tubular structure, the water inlet pipe 2 is interconnected with the upper surface of the mixing barrel 1, and the water inlet pipe 2 is interconnected with the water storage barrel 11. The feed port 21 is arranged at the upper end of the water storage barrel 11 for feeding.

[0030] The closing assembly 3 is arranged on the water storage barrel 11, and is used to close the water inlet pipe 2. The closing assembly 3 includes a first baffle 31, a second baffle 32, a connecting rod 33, and a driving rod 34. The first baffle 31 is a circular plate-shaped structure, and the first baffle 31 is slidably arranged in the water inlet pipe 2. The second baffle 32 is a circular plate-shaped structure, and the second baffle 32 is slidably arranged in the water inlet pipe 2. The connecting rod 33 is a round rod-shaped structure, and the connecting rod 33 is installed on the first baffle 31 and the second baffle 32. The driving rod 34 is a round rod-shaped structure, and the driving rod 34 is installed on the upper surface of the first baffle 31, and the upper end of the driving rod 34 extends to the outside of the water storage barrel 11 and is slidably connected.

[0031] When the staff needs to inject a certain amount of clean water into the mixing barrel 1, the staff needs to move the driving rod 34 upwards, so that the connecting rod 33 and the first baffle 31 can move upwards, so that the first baffle 31 moves into the water storage barrel 11, and then the clean water in the water storage barrel 11 moves into the water inlet pipe 2. Subsequently, when the space between the second baffle 32 and the water storage barrel 11 is full of clean water, the staff only needs to move the driving rod 34 downwards to return the first baffle 31 to the water inlet pipe 2. At this time, the space between the first baffle 31 and the second baffle 32 is full of clean water, and as the second baffle 32 moves, the second baffle 32 moves into the mixing barrel 1, and then the clean water between the first baffle 31 and the second baffle 32 moves into the mixing barrel 1, thereby reducing the difficulty for the staff to inject a certain amount of clean water into the mixing barrel 1.

[0032] The stopper 4 is a block structure, and the stopper 4 is fixed to the upper surface of the driving rod 34 to block the driving rod 34. The stopper 4 reduces the probability that the driving rod 34 moves completely into the storage barrel, thereby improving the use experience of the staff.

[0034] When the staff moves the driving rod 34 upward, the first fixing plate 41 blocks the second fixing plate 5, thereby reducing the difficulty for the staff to judge the distance the driving rod 34 needs to move and reducing the probability of the first fixing plate 41 moving into the mixing barrel 1, thereby improving the staff's user experience.

[0035] A rotating groove 51 is provided on the side wall of the water storage barrel 11, and the rotating rod 6 is a round rod-shaped structure. The rotating rod 6 is rotatably arranged in the rotating groove 51, and the hourglass 61 is connected to the rotating rod 6. When the staff moves the first fixing plate 41 into the water storage barrel 11, the staff needs to keep the driving rod 34 stable and rotate the hourglass 61. When the sand in the hourglass 61 stops moving, the space between the first baffle 31 and the second baffle 32 is filled with clean water, thereby reducing the difficulty of operation for the staff.

[0036] The first magnet block 7 is a block structure, and two first magnet blocks 7 are provided and symmetrically embedded on the side wall of the rotating rod 6. The second magnet block 71 is a block structure, and the second magnet block 71 is embedded on the inner wall of the rotating groove 51, and the second magnet block 71 and the first magnet block 7 are mutually attracted.

[0037] When the hourglasses 61 are perpendicular to each other, one of the first magnet blocks 7 and the second magnet block 71 are attracted to each other, thereby improving the stability of the rotating rod 6 and the hourglass 61, thereby improving the user experience of the device.

[0038] In order to improve the user experience of the staff, a placement groove 8 is provided on the side wall of the limit block 4 to reduce the difficulty of the staff to move the limit block 4, and sealing gaskets 9 are provided on the side walls of the first baffle 31 and the second baffle 32.

[0039] The use principle of the eluent preparation device for ion chromatography in this embodiment is as follows: when the staff needs to prepare the eluent, the staff needs to inject the eluent raw material into the mixing barrel 1 through the feed port 21, and inject enough clean water into the water storage barrel 11. Then, the staff needs to start the closing component 3, so that a certain amount of clean water can be stored between the first baffle 31 and the second baffle 32. Furthermore, the staff only needs to move the first baffle 31 downward to move the clean water between the first baffle 31 and the second baffle 32 into the water storage barrel 11, thereby reducing the difficulty of the staff to quantitatively inject clean water.
