AI Technical Summary
The waste liquid collection device of a liquid chromatograph usually has only one drain pipe. When the drain pipe fails, the waste liquid discharge needs to be suspended until the maintenance is completed, and the efficiency of a single drain pipe is not high.
A waste liquid collection equipment for liquid chromatographs is designed, which uses a diversion pipe to communicate with the main body of the waste liquid collection equipment, and multiple drain ports are controlled through electric valves and servo motors. It is equipped with a double-layer filter mesh structure to realize the diverting and filtration of waste liquid. The servo motor drives the spacer to rotate to switch the drain path to ensure the continuous discharge of waste liquid.
It realizes that the liquid chromatograph does not need to be temporarily discharged when the drain pipe is faulty, which improves the drainage efficiency, and conveniently replaces and cleanses of impurities through the detachable filter structure, improving the reliability and efficiency of the equipment.

[0021] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0022] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The 2nd liquid collecting device of the present invention is the 2nd liquid collecting device of the present invention, and the 2nd liquid collecting device of the present invention has the 2nd liquid collecting device of the present invention can be connected with the 2nd liquid collecting device of the present invention.
[0023] Specifically, sealing rubber is provided on the outer sides of both ends of the second partition plate 7, and the end of the second partition plate 7 close to the first partition plate 6 is in contact with the first partition plate 6 to prevent the waste liquid from flowing into the corresponding waste liquid collection device body 2 when the second partition plate 7 seals one side of the waste liquid collection device body 2.
[0024] As an optimization solution, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a number of limit blocks 9 are symmetrically fixed on both sides of the first partition plate 6 and the inner side of the waste liquid collection equipment body 2, and a first filter screen 10 and a second filter screen 11 are slidably connected inside each two relative limit blocks 9. Openings that match the positions of the first filter screen 10 and the second filter screen 11 are provided on both sides of the waste liquid collection equipment body 2. Sealing plates 12 that match the openings of the waste liquid collection equipment body 2 are fixed on both sides of the waste liquid collection equipment body 2 by bolts to facilitate filtering out impurities in the waste liquid.
[0025] Specifically, the top surface of the waste liquid collection device body 2 is covered with a top cover 13, and the top cover 13 is fixed to the top surface of the waste liquid collection device body 2 by bolts. The first filter screen 10 and the second filter screen 11 are both arranged obliquely inside the waste liquid collection device body 2. The inclined surfaces of the first filter screen 10 and the second filter screen 11 are arranged in a direction away from the first partition plate 6. The mesh number of the first filter screen 10 is smaller than the mesh number of the second filter screen 11. The first filter screen 10 is located at one end close to the guide pipe 3, and the second filter screen 11 is located at one end close to the drain port 5, thereby improving the filtering efficiency of the first filter screen 10 and the second filter screen 11.
[0026] Working principle: When the waste liquid inside the liquid chromatograph body 1 is discharged into the waste liquid collection device body 2 through the guide tube 3, the waste liquid is filtered through the first filter screen 10 and the second filter screen 11, so that the impurities in the waste liquid are filtered out by the first filter screen 10 and the second filter screen 11, and the filtered waste liquid is discharged through the two drain ports 5. When one drain port 5 fails, the servo motor 8 is started at this time, so that the servo motor 8 drives the second partition plate 7 to move, so that the second partition plate 7 moves toward the corresponding drain port 5, so that the second partition plate 7 seals the side of the corresponding drain port 5 inside the waste liquid collection device body 2, and at the same time, the waste liquid continues to be discharged through the other side of the first partition plate 6. When the staff repairs the drain port 5 After the maintenance is completed, start the servo motor 8, so that the servo motor 8 drives the second partition plate 7 to move, thereby moving the second partition plate 7 to the center of the guide tube 3, so that the waste liquid is discharged again through both sides of the first partition plate 6. When the staff needs to replace the first filter 10 and the second filter 11, the bolts on the top surface of the top cover 13 are opened to release the fixation of the top cover 13 and the waste liquid collection equipment body 2. At this time, the staff can remove the top cover 13 and replace the first filter 10 and the second filter 11. When impurities on the first filter 10 and the second filter 11 need to be cleaned, the corresponding impurities can be easily discharged through the openings on both sides of the waste liquid collection equipment body 2 by opening the screws on the corresponding sealing plate 12.
