[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] Please see Figures 1-4 This utility model provides a hazardous waste liquid disposal device, including a disposal box 1. A drive motor 2 is fixedly connected to the top of the disposal box 1. The output end of the drive motor 2 extends into the interior of the disposal box 1. A stirring shaft 7 is rotatably connected to the output end of the drive motor 2. Stirring blades 8 are equidistantly arranged on the outer surface of the stirring shaft 7. The stirring blades 8 are arranged in a circumferential array. A filter assembly is arranged on the inner wall of the disposal box 1 below the stirring shaft 7. The filter assembly includes a groove opened on one side of the inner wall of the disposal box 1. A slider is slidably connected in the groove. A filter screen 9 is fixedly connected to the opposite side of the two sliders. A baffle 10 is fixedly connected to the top edge of the filter screen 9. A rectangular through hole is opened through one side of the disposal box 1 at the position corresponding to the filter screen 9. A connecting block 5 is fixedly connected to the side of the filter screen 9 near the rectangular through hole. A pull block 6 is fixedly connected to the side of the connecting block 5 away from the filter screen 9.

[0023] During operation, the hazardous waste liquid to be treated is first introduced into the treatment tank 1. The top-mounted drive motor 2 is then started. The output end of the drive motor 2 drives the stirring shaft 7, which extends into the treatment tank 1, to rotate. The stirring blades 8, which are equidistantly arranged in a circular array on the outer surface of the stirring shaft 7, rotate synchronously with the stirring shaft 7, thoroughly stirring the hazardous waste liquid in the treatment tank 1 to ensure uniform mixing of the components and improve the subsequent treatment effect. After stirring, the hazardous waste liquid flows downward under its own gravity, passing through the filter assembly located below the stirring shaft 7. The slider in the filter assembly is slidably connected to the inner wall of the treatment tank 1. The filter screen 9 filters the hazardous waste liquid. The baffle 10 at the top edge of the filter screen 9 can prevent the hazardous waste liquid from overflowing from the edge of the filter screen 9 during the filtration process. The filtered hazardous waste liquid is retained at the bottom of the disposal box 1, and the residue produced by filtration is trapped on the filter screen 9. When it is necessary to clean the residue, by pulling the pull block 6 at the outer end of the connecting block 5, which is fixedly connected to the filter screen 9 at the corresponding position of the rectangular through hole on one side of the disposal box 1, the filter screen 9 can be moved to slide along the slide groove through the slider, and the filter screen 9 can be pulled out of the disposal box 1 from the rectangular through hole for residue cleaning. After cleaning, the filter screen 9 can be pushed back to its original position for continued use.

[0024] Furthermore, such as Figure 2 and Figure 3A circular through hole is provided on the top of one side of the treatment box 1 shown. A medicine inlet tube 15 is fixedly connected to one end of the circular through hole near the outside of the treatment box 1. A rotating hole is provided on one side of the top of the medicine inlet tube 15. A rotating shaft is rotatably connected in the rotating hole. A dust cover 16 is fixedly connected to the top of the rotating shaft. A pull rod 17 is fixedly connected to one side of the top of the dust cover 16.

[0025] During operation, first pull the dust cover 16 upwards using the lever 17, causing it to rotate and open around the rotating shaft inside the top hole of the inlet tube 15. The required treatment agent is then injected into the treatment tank 1 through the inlet tube 15 at the top circular through-hole on one side. After injection, the dust cover 16 is rotated in the opposite direction to close the inlet tube 15 to prevent impurities from falling in. Next, the hazardous waste liquid to be treated is introduced into the treatment tank 1. The top drive motor 2 is then started, and its output drives the stirring shaft 7 inside the treatment tank 1 to rotate, causing the equidistantly spaced circular array of stirring blades 8 to interact with the hazardous waste liquid. The agents are thoroughly stirred and mixed to enhance the treatment reaction effect. After stirring, the mixed hazardous waste liquid flows downward under gravity through the filter assembly below the stirring shaft 7. It is filtered by the filter screen 9 fixed by the slider that is slidably connected to the inner wall of the treatment tank 1. The baffle 10 at the top edge prevents the hazardous waste liquid from overflowing. The filtered liquid remains at the bottom of the tank, and the residue is trapped on the filter screen 9. When cleaning, pull the pull block 6 on the connecting block 5 at the rectangular through hole of the treatment tank 1 to pull the filter screen 9 out along the slide for cleaning. After cleaning, it can be pushed back for reuse.

[0026] Furthermore, such as Figure 4 The treatment box 1 shown has a liquid inlet on one side of its top. A feed pipe 12 is fixedly connected to one end of the liquid inlet near the outside of the treatment box 1. A feed funnel 13 is fixedly connected to the top of the feed pipe 12. A feed valve 14 is fixedly installed on one side of the feed pipe 12. A water outlet 11 is opened at the bottom of the treatment box 1. A liquid outlet pipe is fixedly connected to the bottom of the water outlet 11. A liquid outlet valve is fixedly installed on one side of the liquid outlet pipe. A support frame 3 is fixedly fitted onto the outer surface of the treatment box 1. Support legs 4 are fixedly connected to the four corners of the bottom of the support frame 3.

[0027] During operation, the hazardous waste liquid to be treated is introduced through the feed funnel 13 at the top of the feed pipe 12 on one side of the top of the treatment tank 1. The feed funnel 13 can prevent the waste liquid from spilling. After the introduction is completed, the feed valve 14 is closed. Then, the dust cover 16 of the inlet pipe 15 is opened by the pull rod 17, and the treatment agent is injected into the treatment tank 1 through the inlet pipe 15. After the injection, the dust cover 16 is closed to prevent impurities from entering. Then, the drive motor 2 at the top of the treatment tank 1 is started. Its output end drives the stirring shaft 7 inside the tank to rotate. The stirring blades 8, which are equidistantly arranged in a circular array on the outer surface of the stirring shaft 7, rotate synchronously to react the hazardous waste liquid with the agent. Thorough mixing is performed to enhance the treatment reaction. After the reaction is complete, the outlet valve is opened, and the mixture is filtered by the filter screen 9 below the stirring shaft 7 under the action of gravity. The baffle 10 prevents the waste liquid from overflowing. The qualified liquid after filtration is discharged through the outlet pipe at the bottom of the treatment tank 1, and the residue is trapped on the filter screen 9. After filtration, the outlet valve is closed, and the pull block 6 on the side connecting block 5 of the treatment tank 1 is pulled to pull the filter screen 9 out along the inner wall groove for cleaning. After cleaning, it can be pushed back to its original position for reuse. Throughout the process, the support frame 3 and the support legs 4 at the four corners of the bottom provide stable support for the device.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
