DETAILED DESCRIPTION

[0024] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0025] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0026] See also Figure 1-Figure 5 In this embodiment, a dosing mechanism for battery wastewater treatment includes a stirring tank 1, which is provided with a stirring chamber 2 and a drainage chamber 3. The stirring tank 1 is provided with a cover plate 4, and the cover plate 4 is respectively provided with a dosing pipe 5 and a water injection pipe 6 connected to the stirring chamber 2. A rotating rod 7 is provided outside the cover plate 4 and extends into the stirring chamber 2 and is rotatable. Stirring rods 8 are evenly distributed on the rotating rod 7. A cavity is provided in the rotating rod 7, and a telescopic rod 9 is provided in the cavity and extends into the drainage chamber 3 and is rotatable. A rotating plate 10 is symmetrically provided on the telescopic rod 9, which can be fitted with or away from the inner wall of the drainage chamber 3. The part of the rotating rod 7 located outside the cover plate 4 is provided with a driving assembly for driving the telescopic rod 9 to extend and retract in the cavity. The bottom end of the stirring tank 1 is provided with a discharge pipe 11 connected to the drainage chamber 3.

[0027] In this embodiment, the opening of the stirring chamber 2 is set upward, and the cover plate is detachably mounted on the upper end of the stirring tank 1 by bolts. The drainage chamber 3 is funnel-shaped and is arranged at the bottom of the stirring chamber 2 to form the stirring tank 1;

[0028] Among them, through the arrangement of the stirring tank 1, the stirring chamber 2, the drainage chamber 3, the cover plate 4, the water injection pipe 6, the dosing pipe 5, the rotating rod 7, the stirring rod 8 and the discharge pipe 11, the cover plate 4 is fixedly connected to the upper end of the stirring tank 1, and the rotating rod 7 is rotatably mounted on the cover plate 4 through the bearing seat. Of course, a horizontal plate 15 for mounting the bottom end of the rotating rod 7 is provided on the inner wall of the stirring chamber 2, and the bottom end of the rotating rod 7 is rotatably connected to the horizontal plate 15 through a bearing. Thus, the rotating installation of the rotating rod 7 in the stirring chamber 2 is preferably achieved;

[0029] Among them, the drain pipe 11 is connected to the bottom center of the drainage chamber 3, and a one-way valve is provided on the drain pipe 11, so that in actual use, the one-way valve is used to close the drain pipe 11, and the powdered medicine and water are respectively injected into the stirring chamber 2 through the water injection pipe 6 and the dosing pipe 5. The stirring rod 8 is driven to rotate by the rotation of the rotating rod 7, and the powdered medicine and water can be stirred, so that the powdered medicine and water are fully mixed to obtain a medicine solution with a relatively uniform concentration. After the mixing is completed, the one-way valve on the drain pipe 11 is opened, and the medicine solution can be discharged into the drain pipe 11 through the drainage chamber 3, so that it can be added to the subsequent battery wastewater treatment equipment; wherein, the drainage chamber 3 is funnel-shaped, and the drainage of the drainage chamber 3 can make the medicine solution in the stirring tank 1 be discharged more cleanly.

[0030] In this embodiment, the cavity, telescopic rod 9, rotating plate 10 and driving assembly are arranged so that the telescopic rod 9 is slidably connected in the cavity, and the rotating plate 10 is fixedly connected to the lower end of the telescopic rod 9. When the pharmaceutical solution in the stirring chamber 2 is stirred, the driving assembly drives the top end of the telescopic rod 9 to contact the top wall of the cavity. At this time, the telescopic rod 9 moves up so that the rotating plate 10 on it is located in the drainage chamber 3 and does not fit with the inner wall of the drainage chamber 3. The telescopic rod 9 rotates with the rotating rod 7 to drive the rotating plate 10 to rotate, which can stir the pharmaceutical solution in the drainage chamber 3, so that the stirring tank 1 can be fully stirred, and the medicine and water can be mixed more evenly, while avoiding the rotating plate 10 from fitting the inner wall of the drainage chamber 3 for a long time, causing the rotating plate 10 to rotate. Wear of the plate 10; when the stirring is completed and the solution is discharged, when the inner wall of the drainage chamber 3 needs to be cleaned, the telescopic rod 9 is driven by the driving component to slide downward in the cavity, which can drive the rotating plate 10 to fit the inner wall of the drainage chamber 3. After fitting, the rotating plate 10 is rotated to scrape the inner wall of the drainage chamber 3. After scraping is completed, the rotating plate 10 is driven to separate from the inner wall of the drainage chamber 3 by sliding the telescopic rod 9 upward, and clean water is injected into the drainage chamber 3 through the water injection pipe 6. After the clean water is injected, the rotating plate 10 is rotated for stirring. After stirring, the solution is discharged to complete the cleaning of the inner wall of the drainage chamber 3. At the same time, the rotating plate 10 is cleaned, which can avoid the pharmaceutical solution from remaining on the inner wall of the drainage chamber 3, thereby affecting the subsequent dispensing and use of the stirring tank 1. In this embodiment, when the rotating plate 10 stirs the solution in the drainage chamber 3, the rotating plate 10 is separated from the inner wall of the drainage chamber 3. When the inner wall of the drainage chamber 3 is scraped, the rotating plate 10 is in contact with the inner wall of the drainage chamber 3. This can avoid friction between the rotating plate 10 and the inner wall of the drainage chamber 3 when the medicine and water are stirred and mixed, thereby affecting the rotation rate and thus affecting the mixing effect of the medicine and water.

Through the cooperation of the slide groove 100 and the pressure rod 101, the rotation of the rotating rod 7 can drive the telescopic rod 9 and the rotating plate 10 to rotate synchronously.

When the pressure rod 101 squeezes the inclined surface 207, the inclined blocks 206 can be moved away from each other. When the inclined blocks 206 move away from each other until the pressure rod 101 completely passes through the inclined block 206, the second spring 302 pushes the inclined blocks 206 to fit together, and the pressure rod 101 can be stuck under the fitted inclined blocks 206, thereby achieving the fitting of the rotating plate 10 with the inner wall of the drainage chamber 3, and scraping the inner wall of the drainage chamber 3.
