DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1 、 Figure 2 、 Figure 3 As shown, a flow cytometer waste liquid treatment device includes a housing 1, with a liquid inlet 101 and a liquid discharge port 102 respectively provided on the upper and lower sides of the housing 1, two filter frames 4 are obliquely arranged in the housing 1, and the inclination directions of the two filter frames 4 are opposite. The left and right sides of the filter frames 4 are connected to a fixed block 3 fixed to the inner wall of the housing 1 through a slide groove and a slider for sliding back and forth. The outer side of the filter frame 4 is glued with a sealing gasket and is slidably sealed with the front side of the housing 1, and a pull block 401 is integrally formed on the front side of the filter frame 4. A filter screen 5 and a filter membrane 6 are respectively sandwiched in the two filter frames 4, and the filter screen 5 is located above the filter membrane 6;

[0021] A disinfection component and a stirring component for disinfecting the waste liquid are provided below the filter membrane 6 .

[0022] During use, the waste liquid in the flow cytometer enters the housing 1 through the liquid inlet 101 and passes through the filter screen 5 and the filter membrane 6 in sequence. The filter screen 5 first filters the large particles of impurities in the waste liquid. After the filtration is completed, the waste liquid moves downward along the filter screen 5 and enters the filter membrane 6 for fine filtration to filter out smaller particles and microorganisms in the waste liquid. The filter membrane 6 can use a filter membrane with a smaller pore size, such as a 0.2 micron filter membrane. After coarse filtration and fine filtration, the waste liquid enters the bottom of the filter membrane 6 and is disinfected under the action of the disinfection component and the stirring component to reduce the possible pathogens in the waste liquid, thereby realizing multi-stage filtration treatment of the waste liquid by the waste liquid treatment device to reduce the pollution of the waste liquid to the environment. Finally, the disinfected waste liquid can be discharged and collected through the drain port 102. When the waste liquid is completely filtered, the staff can grab the pull block 401 to pull the filter frame 4 out from the front side of the housing 1, and clean and replace the filter screen 5 and the filter membrane 6 in the filter frame 4 to ensure the filtration effect of the filter screen 5 and the filter membrane 6.

[0023] In this embodiment, the disinfection assembly includes a liquid storage tank 8 fixed to the left side of the shell 1 by bolts, an infusion tube 10 sealed and plugged into the left side of the shell 1, and an electromagnetic valve 9 arranged between the infusion tube 10 and the liquid storage tank 8. The liquid storage tank 8 is filled with sodium hypochlorite. During use, after the waste liquid has been filtered through the filter screen 5 and the filter membrane 6, the staff controls the electromagnetic valve 9 to allow the sodium hypochlorite in the liquid storage tank 8 to enter the shell 1 to react with the waste liquid for disinfection. At the same time, the stirring assembly is started to fully mix the sodium hypochlorite with the waste liquid to improve the disinfection effect of sodium hypochlorite on the waste liquid, thereby improving the treatment efficiency of the waste liquid treatment device.

[0024] In this embodiment, a liquid replenishing port is opened on the upper side of the liquid storage tank 8, and a liquid storage cap 14 is threadedly connected to the liquid replenishing port. When in use, the staff can rotate the liquid storage cap 14 and remove it, and then replenish the sodium hypochlorite in the liquid storage tank 8 to ensure the normal operation of the disinfection function of the waste liquid treatment device.

[0025] In this embodiment, the stirring assembly includes a stirring shaft 12 rotatably connected to the left and right sides of the inner cavity of the shell 1 through a sealed bearing, a plurality of stirring blades 13 welded to the stirring shaft 12, and a rotating motor 11 fixed to the right side of the shell 1 by bolts. The output shaft of the rotating motor 11 is sealed and connected to the stirring shaft 12 through the shell 1. When in use, the staff starts the rotating motor 11 so that the rotating motor 11 drives the stirring shaft 12 to rotate. When the stirring shaft 12 rotates, the stirring blades 13 stir the waste liquid in the shell 1, so that the waste liquid and sodium hypochlorite are fully mixed, thereby improving the disinfection effect of sodium hypochlorite on the waste liquid.

[0026] In this embodiment, the liquid inlet 101 is installed with a bellows 15 by bolts, and the end of the bellows 15 away from the shell 1 is threadedly connected to a connector 16. When in use, the connector 16 is connected and fixed to the discharge port of the flow cytometer. At the same time, the bellows 15 can be extended to adjust the direction, further improving the convenience of connecting the waste liquid treatment device with the flow cytometer.

[0027] In this embodiment, a guide block 7 is welded to the upper side of the fixed block 3, and the guide block 7 is inclined from top to bottom toward the filter frame 4. When in use, the guide block 7 can make the waste liquid on the upper side of the fixed block 3 flow downward into the filter frame 4, preventing the waste liquid from accumulating on the upper side of the fixed block 3, thereby further improving the reliability of the waste liquid treatment device when treating waste liquid.

[0028] In this embodiment, the lower side surface of the shell 1 is inclined from top to bottom toward the center along the four sides, and the drain port 102 is located at the center. The end of the drain port 102 located outside the shell 1 is threadedly connected to the drain cover 17. When the waste liquid is processed and discharged, the staff opens the drain cover 17, and the waste liquid in the shell 1 flows downward along the lower side surface of the shell 1 and is discharged from the shell 1, preventing the waste liquid from being discharged incompletely and accumulating at the bottom of the shell 1, thereby improving the efficiency of the shell 1 in discharging waste liquid.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
