Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-6 , the present utility model provides a technical solution: a heavy metal adsorption and elution device, including a support frame 1 and an elution barrel 2 rotatably connected to the support frame 1. A plurality of stirring mechanisms for stirring the soil mixture are arranged inside the elution barrel 2; the stirring mechanism includes a plurality of transmission rods 14 rotatably connected inside the elution barrel 2, and a stirring ring 15 is arranged on each transmission rod 14; a driving assembly for driving the elution barrel 2 to rotate is further arranged on the support frame 1. When the driving assembly drives the elution barrel 2 to rotate, a plurality of transmission rods 14 are driven to rotate in reverse synchronously through a transmission mechanism, driving a plurality of stirring rings 15 to rotate inside the elution barrel 2.

[0024] Among them, the heavy metal adsorption and elution device includes a support frame 1 and an elution barrel 2 rotatably connected to the support frame 1. Specifically, multiple groups of support legs are installed at the bottom of the support frame 1, and anti-slip pads are provided at the bottom of each support leg to improve the stability of the elution device during operation. Specifically, the elution barrel 2 is a prior art. Multiple groups of stirring mechanisms for stirring the soil mixture are arranged inside the elution barrel 2. Therefore, during use, the mixture inside the elution barrel 2 is stirred by the stirring mechanism to improve the separation efficiency of the soil mixture inside the elution device. The stirring mechanism includes multiple groups of transmission rods 14 rotatably connected inside the elution barrel 2, and a stirring ring 15 is arranged on each transmission rod 14; a driving assembly for driving the elution barrel 2 to rotate is also arranged on the support frame 1. When the driving assembly drives the elution barrel 2 to rotate, multiple groups of transmission rods 14 are driven to rotate in reverse synchronously through a transmission mechanism, driving multiple groups of stirring rings 15 to rotate inside the elution barrel 2. Therefore, during the use of this elution device, the elution barrel 2 is driven to rotate by the driving assembly. During the rotation of the elution barrel 2, the mixture inside the elution barrel 2 can be turned over to meet the working requirements. During the rotation of the elution barrel 2, the driving assembly drives multiple groups to rotate in reverse inside the elution barrel 2 through a transmission mechanism, so that the stirring rings 15 on each transmission rod 14 rotate synchronously, thereby being able to stir the mixture inside the elution barrel 2 more fully, improving the separation efficiency of the mixture inside the elution barrel 2, and the use effect is better.

[0025] In the embodiment provided by the present utility model, the driving assembly includes a driving rod 5 rotatably connected to the support frame 1. A driving gear 6 is installed on the driving rod 5, and a toothed ring 7 is installed on the elution barrel 2. The driving gear 6 meshes with the toothed ring 7; a servo motor 4 for driving the driving rod 5 to rotate is arranged on the support frame 1. Therefore, during use, the servo motor 4 is started, the driving gear 6 is driven to rotate through the driving rod 5, and after the driving gear 6 meshes with the toothed ring 7, the elution barrel 2 is driven to rotate to stir the mixture inside the elution barrel 2.

[0026] In the embodiment provided by the present utility model, the transmission mechanism includes a rotating support rod 8 rotatably connected to the elution barrel 2. A main gear 10 is installed on the rotating support rod 8, and a driven gear 13 is installed on each rotating support rod 8. Multiple groups of driven gears 13 are all meshed with the main gear 10; A synchronizing member 9 is arranged between the rotating support rod 8 and the driving rod 5. The synchronizing member 9 includes synchronizing wheels installed on the rotating support rod 8 and the driving rod 5, and the two synchronizing wheels are connected by a synchronous belt for transmission. Therefore, during use, when the driving rod 5 rotates, it can drive the synchronizing wheel on the driving rod 5 to rotate, and drive the rotating support rod 8 to rotate through the cooperation of the synchronous belts. Since the main gear 10 is installed on the rotating support rod 8 and the driven gear 13 is installed on each transmission rod 14, multiple groups of driven gears 13 can be driven to rotate synchronously during the rotation of the main gear 10, and then multiple groups of transmission rods 14 can be driven to rotate synchronously to meet the working requirements.

[0027] In the embodiment provided by the present utility model, a rotating groove 16 is formed on the elution barrel 2, and multiple groups of transmission rods 14 are all rotatably connected in the rotating groove 16, which improves the stability when the transmission rod 14 is connected to the elution barrel 2, and at the same time avoids movement interference between the elution barrel 2 and the transmission rod 14.

[0028] In the embodiment provided by the present utility model, a stirring rod 11 is fixedly connected to the rotating support rod 8, and multiple groups of stirring blades 12 are installed on the stirring rod 11. Therefore, during the rotation of the rotating support rod 8, the rotation of the stirring rod 11 can be further improved. While the stirring rod 11 rotates, it drives multiple groups of stirring blades 12 to rotate, further improving the stirring efficiency.

[0029] In the embodiment provided by the present utility model, a feed inlet and a discharge outlet are formed on the elution barrel 2. A discharge pipeline 3 is installed on the support frame 1, and the discharge pipeline 3 is adapted to the discharge outlet. Therefore, during use, a mixture and other raw materials such as an eluent are added into the elution barrel 2 through the feed inlet. After the work is completed, the mixture inside the elution barrel 2 is discharged into the separation device through the discharge outlet and the discharge pipeline 3, so as to separate the metal in the soil from the soil to meet the working requirements. Among them, the position where the elution barrel 2 stays can be controlled through program control, which can ensure that the discharge outlet and the discharge pipeline 3 are exactly communicated, facilitating the discharge of the mixture inside the elution barrel 2. Among them, a feed inlet valve and a discharge outlet valve are arranged on the elution barrel 2 to control the feeding and discharging of the elution barrel 2.

[0030] It should be noted that the electrical equipment involved in this application can be powered by a storage battery or an external power supply.
