Specific embodiments

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Such as Figure 1-6As shown in the figure, a decolorization device for aluminum trichloride wastewater includes a number of reaction tanks 1. A stirring device is installed above the reaction tank 1. The stirring device includes a top shell 2 and a connecting plate 12 slidably connected to the inner side wall of the top shell 2. There is a sandwich layer 16 on one side inside the top shell 2. Three linearly distributed gears 7 are rotatably connected to the upper surface of the connecting plate 12. One of the gears 7 is located below the sandwich layer 16. The gear 7 in the middle meshes with the gears 7 on its two sides. A slider 10 inserted into the outer side wall of the sandwich layer 16 in the vertical direction is rotatably connected to the top of the gear 7 in the middle. Spring rods 14 are rotatably connected to the tops of the gears 7 on both sides. One of the spring rods 14 away from the sandwich layer 16 is fixedly installed on the inner wall top of the top shell 2. The bottom of one of the gears 7 away from the sandwich layer 16 penetrates through the connecting plate 12 and is fixedly connected to a connecting rod 13. A gear 7 that can rotate and revolve is rotatably connected to the end of the connecting rod 13 with a larger rotation radius. A stirring frame 6 that penetrates through the connecting rod 13 and extends into the reaction tank 1 is fixedly connected to the self-rotation point of the gear 7 below the connecting plate 12. An eccentric wheel 8 is also rotatably connected to the outer side wall of the sandwich layer 16. A transmission rod 9 sleeved on the edge of one side of the eccentric wheel 8 is rotatably connected to the slider 10. A corner double-shaft planetary reducer 11 is fixedly connected inside the sandwich layer 16. One output end of the corner double-shaft planetary reducer 11 penetrates through the side wall of the sandwich layer 16 and is fixedly connected to the eccentric wheel 8, and the other output end is fixedly connected downward to the spring rod 14 close to the sandwich layer 16. A number of spring rods 14 are also fixedly connected between the bottom of the sandwich layer 16 and the connecting plate 12. A circular tooth groove 17 is fixedly connected to the bottom of the connecting plate 12. The circular tooth groove 17 meshes with the gear 7 at one end of the connecting rod 13. A support plate 3 is fixedly connected to the side of the top shell 2. The bottom of the reaction tank 1 is installed on the support plate 3.

[0026] With this technical solution, the stirring frame 6 can rotate around one end of the connecting rod 13 while rotating, and the stirring frame 6 can also lift while rotating, stirring and interacting with the waste liquid above and below in the reaction tank 1, expanding the stirring range of the stirring frame 6 and accelerating the efficiency of the redox reaction of the waste liquid. The specific implementation method is that the output end of the angular double-shaft planetary reducer 11 drives the eccentric wheel 8 and the gear 7 located above the connecting plate 12 to rotate at the same time. The rotation of the eccentric wheel 8 drives the slider 10 to slide up and down reciprocally, and then drives the gear 7 and the connecting plate 12 to move up and down reciprocally. The connecting plate 12 drives the connecting rod 13 to move up and down reciprocally. And because the connecting rod 13 is fixed to the gear 7 located above the connecting plate 12, the connecting rod 13 rotates while moving up and down reciprocally. The setting of the circular tooth groove 17 enables the gear 7 located below the connecting plate 12 to rotate self. The connecting rod 13 can drive the gear 7 to revolve and lift, so as to realize that the stirring frame 6 rotates and revolves in the reaction tank 1 while lifting. In addition, the main shaft of the angular double-shaft planetary reducer 11 is fixedly connected to the gear 7, and the output shaft of the other deceleration part is fixed to the eccentric wheel 8.

[0027] As Figure 6 shown, a water level control valve 5 is provided at the flow port between the reaction tanks 1.

[0028] With this technical solution, there are three reaction tanks 1, and the side surfaces of the reaction tanks 1 at both ends are provided with a liquid inlet and a liquid outlet. And there is a communication port between the middle reaction tank 1 and the reaction tanks 1 on both sides. And the water level control valve 5 provided at the communication port can control the flow rate of the aluminum trichloride waste liquid in the previous reaction tank 1 flowing into the next reaction tank 1 according to the liquid level of the next reaction tank 1, avoiding that the aluminum trichloride waste liquid in a certain reaction tank 1 is too much and affecting the effect of its chemical reaction.

[0029] As Figure 1 and Figure 6 shown, it also includes a medicine delivery pump 4, and a plurality of medicine outlets 15 are arranged in a linear array on the output pipeline of the medicine delivery pump 4.

[0030] With this technical solution, a medicine delivery pump 4 is provided on one side of each reaction tank 1. The medicine delivery pipeline of the medicine delivery pump 4 enters the interior of the reaction tank 1 through the upper part of the reaction tank 1. And the evenly distributed medicine outlets 15 above can increase the surface area of the liquid medicine mixed with the aluminum trichloride waste liquid after entering the reaction tank 1, thus accelerating the efficiency of the chemical reaction with the aluminum trichloride waste liquid. Further, the liquid medicine added by the medicine delivery pump 4 in the first reaction tank 1 is used to adjust the pH value of the aluminum trichloride waste liquid, the liquid medicine added by the medicine delivery pump 4 in the second reaction tank 1 is used to oxidize and reduce the organic matter pigment impurities in the aluminum trichloride waste liquid, and the liquid medicine added by the medicine delivery pump 4 in the third reaction tank 1 is used to neutralize the pH value of the aluminum trichloride waste liquid.

[0031] Working principle: The waste liquid of aluminum trichloride is discharged into the reaction tank 1 through the liquid inlet, and the medicament enters the reaction tank 1 through the medicine delivery pump 4. Start the corner double-shaft planetary reducer 11. The output end of the corner double-shaft planetary reducer 11 drives all the gears 7 to rotate, and the other output end drives the eccentric wheel 8 to rotate. The rotation of the eccentric wheel 8 drives the connecting plate 12 to move up and down, and the up and down movement of the connecting plate 12 drives the stirring frame 6 to move up and down. The rotation of the gear 7 drives the stirring frame 6 to revolve and rotate, so that the stirring frame 6 stirs in the reaction tank 1. After the reaction is completed, it enters the next reaction tank 1 through the communication port.

[0032] The wiring diagrams of the medicine delivery pump 4 and the corner double-shaft planetary reducer 11 in the present utility model belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the medicine delivery pump 4 and the corner double-shaft planetary reducer 11 will not be explained in detail.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
