Description

Technical Field

[0001] This utility model relates to the field of heavy metal capture technology, specifically to a heavy metal capture device based on thiol compounds. Background Technology

[0002] Heavy metal wastewater refers to wastewater containing heavy metals discharged during industrial production processes such as mining, metallurgy, machinery manufacturing, chemical industry, electronics, and instrumentation. Heavy metal (such as cadmium, nickel, mercury, zinc, etc.) wastewater is one of the most serious industrial wastewaters that pollute the environment and pose the greatest threat to human health. Heavy metals in wastewater generally cannot be decomposed or destroyed, but they can be captured by the specific binding of thiol compounds with heavy metal ions to form stable complexes. However, when heavy metals react with thiol compounds, the lack of effective stirring measures makes it difficult for thiol compounds to react fully with heavy metal ions. Based on this, we propose a heavy metal capture device based on thiol compounds. Utility Model Content

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1 like Figures 1-5 As shown, this embodiment proposes a heavy metal capture device based on thiol compounds, including a capture tank body 1, a transmission shaft 2 rotatably connected to the top of the capture tank body 1, a stirring shaft 3 vertically slidably connected to the middle of the transmission shaft 2, a stirring plate 4 fixedly connected to one end of the stirring shaft 3 inside the capture tank body 1, a positioning seat 5 fixedly connected to the top of the capture tank body 1, a transmission assembly 6 mounted on the positioning seat 5, a driving spur gear 7 fixedly connected to the outer side of the transmission shaft 2, and the transmission assembly 6 cooperating with the driving spur gear 7 to drive the stirring shaft 3 to rotate; In this embodiment, a liquid filling pipe is fixedly connected to the top of the capture tank body 1, and a plug is provided at the top of the liquid filling pipe; In this embodiment, a drain pipe is fixedly connected to the bottom of the outer side of the capture tank body 1, and a solenoid valve is installed on the drain pipe. In this embodiment, an observation window is provided on the outside of the capture tank body 1, and a transparent observation plate is fixedly connected inside the observation window. Through the setting of the observation window, the capture status of heavy metals inside the capture tank body 1 can be intuitively fed back. In this embodiment, the transmission shaft 2 is a hollow structure, and a linkage groove is provided on the inner wall of the transmission shaft 2. A linkage bar is fixedly connected to the outer side of the stirring shaft 3, and the linkage bar is also slidably connected inside the linkage groove. Through the setting of the linkage groove and the linkage bar, when the stirring shaft 3 is vertically displaced, the linkage bar can be used to vertically limit the stirring shaft 3. When the transmission shaft 2 rotates, since the linkage bar is still located inside the linkage groove, the stirring shaft 3 can rotate with the transmission shaft 2. In this embodiment, stirring blades are fixedly connected to both ends of the bottom of the stirring plate 4, and the stirring blades are inclined. By setting the stirring plate 4, it can come into contact with the heavy metal liquid in the main body of the capture tank 1 over a larger range, thus ensuring the application effect of the stirring plate 4. Example 2 like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a transmission component 6; In this embodiment, the transmission assembly 6 includes a guide plate 8, an extension plate 10, and a transmission motor 11. A guide groove 9 is provided in the middle of the guide plate 8. An extension plate 10 is fixedly connected to the middle of the top of the guide groove 9, and the extension plate 10 is also rotatably connected to the top of the stirring shaft 3. The top of the positioning seat 5 is fixedly connected to the transmission motor 11. An eccentric plate 12 is fixedly connected to the output end of the transmission motor 11. The end of the eccentric plate 12 away from the transmission motor 11 is also movably connected to the inside of the guide groove 9. A central shaft 13 is rotatably connected to the bottom of the positioning seat 5. In this embodiment, a guide pin is fixedly connected to the end of the eccentric plate 12 away from the drive motor 11, and the eccentric plate 12 is movably connected to the inside of the guide groove 9 through the guide pin. By setting the guide pin, when the eccentric plate 12 rotates, it can drive the guide pin to move inside the guide groove 9, thereby driving the guide plate 8 to make adaptive adjustments. The transmission assembly 6 also includes an acceleration spur gear 14, a linkage spur gear 15, and a transmission rack 16. The acceleration spur gear 14 and the linkage spur gear 15 are fixedly connected to the outer side of the central shaft 13, and the acceleration spur gear 14 is meshed with the drive spur gear 7. The transmission rack 16 is laterally slidably connected to the bottom end of the inner side of the positioning seat 5, and the transmission rack 16 is also meshed with the linkage spur gear 15. One end of the transmission rack 16 is fixedly connected to a mounting ear A17, one end of the mounting ear A17 is rotatably connected to a linkage plate 18, one end of the guide plate 8 is fixedly connected to a mounting ear B19, and the end of the linkage plate 18 away from the mounting ear A17 is also rotatably connected to the mounting ear B19. In this embodiment, a limiting block is fixedly connected to the bottom of the inner side of the positioning seat 5, and a straight groove is provided on the back of the transmission rack 16. The transmission rack 16 is also connected to the outside of the limiting block through the straight groove. In this embodiment, a pivot is provided at the end of the mounting ear A17 and mounting ear B19 that are close to each other, and the linkage plate 18 is connected between the mounting ear A17 and mounting ear B19 through the pivot. The pivot can stably form the assembly of the linkage plate 18, making the linkage of the linkage plate 18 smoother.

[0019] A specific application of the above two embodiments is as follows: First, the heavy metal liquid is introduced into the body 1 of the capture tank. Then, according to the concentration of heavy metal and the amount of water, an appropriate amount of mercapto compound is added into the body 1 of the capture tank. The sulfur atom in the mercapto compound has a lone pair of electrons, which can combine with heavy metal ions such as Hg²⁺, Cu²⁺, and Pb²⁺ through coordinate bonds to form insoluble or stable complexes, thereby achieving the capture and removal of heavy metals. Then, the drive motor 11 is started to drive the eccentric plate 12 to rotate. With the connection between the eccentric plate 12 and the guide groove 9, the guide plate 8 can be driven to move back to the original position during the continuous rotation of the eccentric plate 12. With the connection between the extension plate 10 and the stirring shaft 3, the stirring shaft 3 can follow the adjustment of the guide plate 8, thereby changing the position of the stirring plate 4 inside the capture tank body 1. When the guide plate 8 moves vertically, since the linkage plate 18 is connected between the guide plate 8 and the transmission rack 16, when the guide plate 8 moves, the linkage plate 18 can push the transmission rack 16 back to the original position, causing the transmission rack 16 to reciprocate to move the linkage spur gear 15, thereby driving the acceleration spur gear 14 to rotate under the support of the central shaft 13. With the help of the acceleration spur gear 14, the drive spur gear 7 is moved, and then the transmission shaft 2 drives the stirring shaft 3 to rotate, and finally the heavy metal liquid is stirred by the stirring plate 4. Furthermore, since the transmission rack 16 is reciprocating, the rotation direction of the stirring disc 4 will also change when the transmission rack 16 reverses direction, thereby avoiding the occurrence of eddies in the main body of the capture tank 1.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
