This storage method has many drawbacks. On the one hand, impurities such as oxygen and moisture in the air are easy to react with the flow phase, which changes the composition of the flow phase, and then affects its performance and effect when used again, for example, it may reduce the purity of the flow phase, change its pH value, etc., so that the recovered flow phase cannot meet the requirements of subsequent process, increases the production cost and resource waste. On the other hand, long-term contact with air may also promote the volatilization or oxidation of some components in the flow phase, produce odor and harmful substances, not only pollute the environment, but also may pose potential threat to the health of operators. Therefore, a recovery flow phase receiving tank is proposed to solve the above problems. SUMMARY

[0022] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0023] Please refer to Figs. 1-3 The recovery mobile phase receiving tank in the embodiment comprises a tank body 1, the tank body 1 is used as a main container of the whole device, and provides a stable storage space for the recovery mobile phase, and the inner side of the tank body 1 is provided with a sealing assembly for preventing liquid from contacting air.

[0024] Please refer to Fig. 1 In the embodiment, the sealing assembly comprises a partition plate 2 fixedly connected to the inner side of the tank body 1, the inner side of the partition plate 2 is fixedly connected with a connecting pipe 3, the partition plate 2 preliminarily divides the internal space of the tank body 1, and plays a certain separating and supporting role, the inner side of the partition plate 2 is fixedly connected with the connecting pipe 3, the connecting pipe 3 is used as a liquid flow channel, and allows the recovery mobile phase to flow from the upper region of the tank body 1 into the space below the partition plate 2, the inner side of the tank body 1 is fixedly connected with a guide rod 4, the outer side of the guide rod 4 is slidingly connected with a floating plate 5, the guide rod 4 provides a stable guide path for the floating plate 5 to move up and down, and ensures that the floating plate 5 remains stable during the movement and cannot deviate or shake, and the top of the floating plate 5 is fixedly connected with a sealing gasket 6, when the floating plate 5 rises to the position of the connecting pipe 3 along with the liquid surface, the sealing gasket 6 can tightly fit the lower end of the connecting pipe 3, and the purpose of preventing liquid from contacting air is achieved.

[0025] Specifically, the inner side of the tank body 1 is fixedly connected with a mesh frame 7, and the mesh frame 7 is located above the partition plate 2, and the inner side of the mesh frame 7 is fixedly connected with a filter screen 8.

[0026] It should be noted that the main role of the filter screen 8 is to preliminarily filter the recovery mobile phase entering the tank body 1, remove possible larger particle impurities, solid residues and the like, and prevent these impurities from entering the inside of the tank body 1 to affect subsequent use or cause damage to the equipment.

[0027] Specifically, the number of the guide rods 4 is two, both of the guide rods 4 are located below the partition plate 2, the inner side of the floating plate 5 is provided with guide holes matched with the guide rods 4 on the left and right sides, the guide rods 4 are slidingly connected to the inner sides of the corresponding guide holes, the upper and lower ends of the left guide rod 4 are both bent to the left and fixedly connected with the inner left side wall of the tank body 1, and the upper and lower ends of the right guide rod 4 are both bent to the right and fixedly connected with the inner right side wall of the tank body 1.

[0028] It should be noted that the design of the double guide rod can provide more stable support and guidance for the floating plate 5, avoid the inclination or jamming phenomenon of the floating plate 5 during movement, and the left and right parts of the inner side of the floating plate 5 are provided with guide holes matched with the guide rods 4, and the guide rods 4 are slidingly connected to the inner side of the corresponding guide holes. This structure makes the floating plate 5 smoothly slide up and down along the guide rod 4.

[0029] Specifically, the bottom of the floating plate 5 is fixedly connected with two groups of floating balls 501, and the two groups of floating balls 501 are arranged on the front and back of the bottom of the floating plate 5, respectively. The number of the two groups of floating balls 501 is seven, and the seven floating balls 501 in the same group are arranged equidistantly along the left and right directions of the floating plate 5.

[0030] It should be noted that the combination of multiple floating balls 501 greatly increases the buoyancy of the floating plate 5 as a whole, so that the floating plate 5 can respond more sensitively to the change of the liquid level. When the liquid level in the tank 1 rises, the buoyancy of the floating ball 501 increases, thereby pushing the floating plate 5 to move upward; when the liquid level drops, the buoyancy of the floating ball 501 decreases, and the floating plate 5 moves downward under the action of its own gravity. This design ensures that the floating plate 5 can accurately follow the change of the liquid level height and timely realize the adhesion or separation of the sealing gasket 6 and the connecting pipe 3.

[0031] Specifically, the top of the tank 1 is fixedly connected with a liquid injection pipe 101, and the bottom of the tank 1 is fixedly connected with a liquid discharge valve 102 and four supporting legs 103.

[0032] It should be noted that the liquid injection pipe 101 is a channel for the recovered mobile phase to enter the tank 1, and the recovered mobile phase can be conveniently injected into the tank 1 through the liquid injection pipe 101 for storage and processing. The bottom of the tank 1 is fixedly connected with a liquid discharge valve 102, which is used to control the discharge of the recovered mobile phase in the tank 1. When the recovered mobile phase is needed, the liquid discharge valve 102 can be opened to discharge the liquid from the tank 1. The bottom of the tank 1 is also fixedly connected with four supporting legs 103, which are evenly distributed on the bottom of the tank 1 to provide stable support for the tank 1, ensuring that the tank 1 will not shake or tilt during use, and also facilitating the placement and installation of the tank 1.

[0033] The working principle of the above embodiment is as follows:

[0034] When the recovered mobile phase liquid is injected into the tank body 1 through the injection pipe 101, the liquid first passes through the filter screen 8 in the screen frame 7, the filter screen 8 filters the impurity particles in the liquid, ensures that the liquid entering the tank body 1 is relatively pure, as the liquid is continuously injected, the liquid level gradually rises, the floating ball 501 at the bottom of the floating plate 5 first contacts the liquid, is subjected to the buoyancy of the liquid, and provides sufficient buoyancy to push the floating plate 5 to move upward, the floating plate 5 stably rises along the axial direction of the guide rod 4 under the guidance of the guide rod 4, as the floating plate 5 continuously rises, the sealing gasket 6 gradually approaches the connecting pipe 3, when the liquid level rises to a certain height, the floating plate 5 drives the sealing gasket 6 to tightly adhere to the port of the connecting pipe 3, thereby isolating the inside of the tank body 1 from the outside air, and preventing the liquid from contacting the air.

[0035] The mounting mode, the connecting mode or the setting mode disclosed in the embodiment are all common mechanical connecting modes, and can be implemented as long as the beneficial effects can be achieved.
