[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0010] Reference Figures 1 to 8 One embodiment provided by this utility model: A pharmaceutical experimental waste liquid collection device includes a housing 1, which is used to house and protect the internal structure for stability. A conveying pipe 4 is movably inserted into the top of the housing 1 for conveying and pouring waste liquid generated during the experiment. An inlet 3 is fixedly connected to the top of the conveying pipe 4 to facilitate the pouring of waste liquid and prevent splashing. A dustproof plate 2 is movably pressed against the top of the inlet 3 for sealing the device when it is not in use to prevent dust and other substances from affecting the device. A connecting pipe 9 is threadedly connected to the end of the conveying pipe 4 inserted into the housing 1 for auxiliary filtration of waste liquid. It should be noted that: a pressing assembly is provided on the outer surface of the connecting tube 9, including a button 10 slidably connected inside the connecting tube 9. The button 10 is designed for easy operation. A pressure plate 11 is fixedly connected to the button 10. By pressing the button 10, the pressure plate 11 slides inside the connecting tube 9. Telescopic rods 12 are fixedly connected to the upper and lower ends of the button 10 away from the outer surface of the connecting tube 9, respectively. The telescopic rods 12 are used for resetting the button 10 and the pressure plate 11. The other end of the telescopic rod 12 is fixedly connected to the connecting tube 9, and the other end is fixedly connected to the outer surface of the connecting tube 9. A spring 13 is fitted on the outer surface of the telescopic rod 12. The spring 13 is used to assist the resetting of the pressure plate 11. One end of the spring 13 is fixedly connected to the outer surface of the button 10 near the connecting pipe 9. A storage tank 8 is inserted and fixed at the bottom of the connecting pipe 9. The storage tank 8 is used to collect the filtered waste liquid. The storage tank 8 is slidably connected to the housing 1. An exhaust pipe 14 is movably inserted at the top of the storage tank 8. The exhaust pipe 14 is used to discharge the gas generated by the filtered waste liquid. The other end of the exhaust pipe 14 passes through the outer surface of the housing 1. The exhaust pipe 14 is an L-shaped frame. An anti-slip layer is provided on the outer surface of the handle 6. A filter device 15 is installed inside the connecting pipe 9. The filter device 15 is used to filter the waste liquid in the experiment. The filter device 15 is a cylindrical filter device with several microporous filter membranes inside. An elastic rod 18 is fixedly connected to the outer surface of the filter device 15. The elastic rod 18 is used to assist in fixing the filter device 15 in the connecting pipe 9. A sliding block 17 is fixedly connected to the other end of the elastic rod 18. The sliding block 17 is used to fix the filter device 15 in the connecting pipe 9. The sliding block 17 enters the horizontal slot in the connecting pipe 9 through the vertical slot at the top of the connecting pipe 9 and abuts against the pressure plate 11. Several sliding grooves 16 are opened on the filter device 15. Several fixing blocks 19 are fixedly connected inside the connecting pipe 9. The sliding grooves 16 and the fixing blocks 19 slide against each other. Reference Figure 1 and Figure 8 Two baffles 5 are rotatably connected to the outer surface of the housing 1. The baffles 5 protect the internal structure and are opened when the filter device 15 needs to be replaced or the storage tank 8 needs to be removed. A handle 6 is fixedly connected to the outer surface of the baffle 5 near the connecting pipe 9, and a pull button 7 is fixedly connected to the outer surface of the other baffle 5. The handle 6 and the pull button 7 are provided for easy operation.
[0011] Working principle: When using this device, first open the baffle 5 at the bottom of the housing 1, then place the storage tank 8 inside the housing 1, and install the connecting pipe 9 and the filter device 15 outside the housing 1. The filter device 15 is installed inside the connecting pipe 9 by pressing and sliding. After the connecting pipe 9 and the filter device 15 are installed, open the baffle 5 on the upper side of the housing 1, then align the connecting pipe 9 with the position of the storage tank 8. Finally, insert the inlet 3 and the outlet 4 from the slot in the top of the housing 1, and connect them to the connecting pipe 9 by rotating. At this time, the device is installed and can be used for waste liquid filtration. The filtration operation steps are as follows: the waste liquid generated in the experiment is poured into the feed inlet 3, the waste liquid reaches the connecting pipe 9 through the feed pipe 4, the filter device 15 inside the connecting pipe 9 completes the filtration of the waste liquid, the filtered waste liquid enters the storage tank 8 to wait for processing, during the waiting process, the gas generated by the waste liquid is discharged from the shell 1 through the exhaust pipe 14. When the filter device 15 needs to be replaced, first, rotate and pull the inlet 3 and the conveying pipe 4 upwards to detach them from the housing 1 and the connecting pipe 9. After the inlet 3 and the conveying pipe 4 are removed, hold the handle 6 to expose the connecting pipe 9. Then, remove the connecting pipe 9 outside the housing 1. Press the buttons 10 on both sides of the connecting pipe 9 with one hand. Under the pushing force of the buttons 10, the pressure plate 11 presses against the sliding block 17. The sliding block 17 slides into the connecting pipe 9 under force. When the sliding block 17 disengages from the horizontal slot on the connecting pipe 9, the restriction on the filter device 15 is removed. Use the other hand to pull the filter device upwards. Place 15 to allow the filter device 15 to slide out of the connecting pipe 9. After replacement, first press the two sliding blocks 17, then align the sliding groove 16 on the filter device 15 with the fixing block 19 and slide it into the connecting pipe 9. When the filter device 15 cannot slide in the connecting pipe 9, it indicates that the filter device 15 has reached the designated position. At this time, since the inner wall of the connecting pipe 9 is constantly pressing against the sliding block 17, when the filter device 15 reaches the designated position, it indicates that the sliding block 17 has reached the position of the hole opened in the connecting pipe 9. At this time, the restriction of the connecting pipe 9 on the sliding block 17 is removed, and the filter device 15 is fixed in the connecting pipe 9 under the force of the elastic rod 18.
[0012] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
