[0030] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 2 - 4, an embodiment provided by the present utility model: a sewage treatment device for the pharmaceutical industry, including a treatment tank 1 for treating sewage. The solid-liquid separation of sewage is achieved through the components in the treatment tank 1. An inlet flange is provided on the upper inner wall of the treatment tank 1, and an outlet flange is provided on the right inner wall of the treatment tank 1. A first telescopic rod 11 is fixedly connected to the upper inner wall of the treatment tank 1. The operation of the first telescopic rod 11 can drive the fixed frame 8 to slide on the inner wall of the treatment tank 1. The bottom outer wall of the first telescopic rod 11 is fixedly connected to the fixed frame 8. The fixed frame 8 provides support for the installation of the filter plate 7. A limiting hole is provided on the upper inner wall of the fixed frame 8. The filter plate 7 is slidably connected to the upper inner wall of the fixed frame 8. The filter plate 7 is used to separate the solid and liquid of the sewage entering the treatment tank 1. A fixed block 12 is fixedly connected to the upper inner wall of the filter plate 7. There are three fixed blocks 12, and the fixed blocks 12 provide support for the movement of the pressing block 13. A circular groove is opened on the right inner wall of the fixed block 12. The lower outer wall of the fixed block 12 is slidably connected to the upper inner wall of the fixed frame 8. The bottom inner wall of the fixed block 12 is elastically connected to the pressing block 13 through a spring 15. The upper outer wall of the pressing block 13 is tapered. By pressing down the pressing block 13, the spring 15 is compressed, so that the limiting ball 14 is released from fixation, and the limiting ball 14 can move into the fixed block 12. When the pressing block 13 is released, the pressing block 13 moves upward under the elastic force of the spring 15, so that the right outer wall of the limiting ball 14 moves out of the fixed block 12. The pressing of the pressing block 13 fixes the limiting ball 14. The outer wall of the pressing block 13 is slidably connected to the upper inner wall of the fixed block 12. An annular groove is opened on the inner wall of the pressing block 13. One end of the spring 15 is fixedly connected to the bottom outer wall of the fixed block 12, and the other end of the spring 15 is fixedly connected to the bottom outer wall of the pressing block 13. The right outer wall of the pressing block 13 contacts the limiting ball 14. By releasing the pressing block 13, the elastic force of the spring 15 makes the right outer wall of the limiting ball 14 leave the inner wall of the fixed block 12 and be clamped on the upper inner wall of the fixed frame 8 to fix the filter plate 7 on the upper inner wall of the fixed frame 8. A stirring assembly is provided on the upper inner wall of the treatment tank 1 for stirring the sewage. A flow disturbance assembly is provided on the front inner wall of the treatment tank 1 for disturbing the flow of the sewage during stirring.

[0032] Refer to Figure 2, The stirring assembly includes a second telescopic rod 2. The operation of the second telescopic rod 2 drives the movement of the mounting frame 3. The outer wall of the upper end of the second telescopic rod 2 is fixedly connected to the inner wall of the upper end of the treatment tank 1. The outer wall of the bottom end of the second telescopic rod 2 is fixedly connected with a mounting frame 3. The mounting frame 3 provides support for the installation of the motor 4. A motor 4 is fixedly connected inside the mounting frame 3. The operation of the motor 4 drives the rotation of the connecting shaft 5. The connecting shaft 5 penetrates and is rotatably connected to the inner wall of the bottom end of the mounting frame 3. The connecting shaft 5 drives the rotation of the stirring plate 6 through the operation of the motor 4. The stirring plate 6 is fixedly connected to the outer wall of the connecting shaft 5. The rotation of the stirring plate 6 drives the stirring of the sewage. During stirring, a dissolving solution (such as dilute sodium hydroxide solution) is dropped into the treatment tank 1 to react with substances such as oil stains to generate substances with less environmental pollution.

[0033] Refer to Figure 1 and Figure 2 , The flow disturbing assembly includes a fixing strip 10. The fixing strip 10 provides support for the movement of the moving strip 9. The outer wall of the front end of the fixing strip 10 is fixedly connected to the inner wall of the front end of the treatment tank 1. The moving strip 9 is slidably connected to the inner wall of the bottom end of the fixing strip 10. The moving strip 9 moves through the movement of the fixing frame 8. The moving strip 9 forms a flow disturbing effect on the rotating sewage during sewage stirring, making the stirring more sufficient. The outer wall of the front end of the moving strip 9 is slidably connected to the inner wall of the front end of the treatment tank 1. The outer wall of the bottom end of the moving strip 9 is fixedly connected to the outer wall of the upper end of the fixing frame 8.

[0034] Working principle: Sewage enters the interior of the treatment tank 1 through the water inlet flange on the inner wall of the upper end of the treatment tank 1. First, the filter plate 7 separates solid and liquid of the sewage, and the solid substances are intercepted on the filter plate 7. Then, the stirring assembly starts to work. The second telescopic rod 2 drives the movement of the mounting frame 3. The motor 4 inside the mounting frame 3 operates to drive the rotation of the connecting shaft 5, so that the stirring plate 6 on the connecting shaft 5 rotates to stir the sewage. During the stirring process, a dissolving solution (such as dilute sodium hydroxide solution) is dropped into the treatment tank 1 to react with substances such as oil stains to generate substances with less environmental pollution. While stirring, the flow disturbing assembly plays a role. When the fixing frame 8 slides, it drives the moving strip 9 to move on the fixing strip 10, and the moving strip 9 forms a flow disturbing effect on the rotating sewage, making the stirring more sufficient. When it is necessary to disassemble or replace the filter plate 7, start the second telescopic rod 2 to drive the mounting frame 3 and the like to move upward, and then start the first telescopic rod 11 to drive the filter plate 7 to move upward through the fixing frame 8. Press down the pressing block 13 to squeeze the spring 15, so that the limiting ball 14 releases the fixation, and then the filter plate 7 can be removed from the fixing frame 8.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
