Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an activated carbon tank that automatically adsorbs precious metals. Background Technology

[0002] Activated carbon tanks are a key piece of equipment widely used in wastewater treatment and precious metal recovery. Their core function is to efficiently capture and recover precious metal elements from wastewater through the adsorption of activated carbon.

[0003] Traditional activated carbon tanks typically employ a single-layer fixed filling structure, which suffers from limited adsorption efficiency, a tendency for the activated carbon layer to become clogged by impurities, shortened lifespan, and cumbersome maintenance and replacement procedures leading to prolonged downtime. Furthermore, the influent system lacks an effective pretreatment mechanism, allowing large particles to directly enter the tank and potentially accelerate activated carbon deterioration, thus affecting the overall treatment effect. In addition, the existing equipment has a rigid structure, making it difficult to flexibly adjust the internal water distribution according to actual water flow conditions, which limits the contact efficiency between wastewater and activated carbon. Therefore, there is an urgent need for an improved activated carbon tank that can achieve high-efficiency adsorption, is easy to maintain, and has influent pretreatment capabilities to enhance the stability and economy of precious metal adsorption. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides an activated carbon canister that automatically adsorbs precious metals, which has the effects of high-efficiency adsorption, stable structure and easy maintenance.

[0005] The technical solution adopted by this utility model is as follows: it includes a support leg and a tank body placed on the ground. The outer side of the tank body is fixedly installed on the top of the support leg. A sealing cover is installed at one end of the tank body. A water inlet pipe is fixedly installed through the sealing cover. A pre-treatment water inlet assembly is threadedly installed on the outer side of the water inlet pipe. Multiple water outlet pipes are fixedly installed through the outer side of the tank body. A first limiting frame is fixed on the inner wall of the tank body. A first filter frame is fixedly installed on the inner side of the sealing cover. A first protrusion is fixed on the outer side of the first filter frame.

[0008] Preferably, in order to enhance the adsorption capacity of precious metals and achieve stratified filtration, multiple sets of water outlet holes are provided on the outer side of the second filter frame, and a second activated carbon plate for adsorbing precious metals is provided inside the second filter frame.

[0009] Preferably, in order to improve adsorption efficiency and material durability, both the first activated carbon plate and the second activated carbon plate are made of coconut shell activated carbon with high specific surface area.

[0010] Preferably, in order to realize the pretreatment function at the inlet end and facilitate maintenance, the pretreatment inlet assembly includes a fixing frame and a connecting pipe. The fixing frame is threaded on the outside of the inlet pipe, and the connecting pipe is fixed inside the fixing frame.

[0013] The beneficial effects of this utility model are as follows: By setting a double-layer filter frame structure and a high specific surface area coconut shell activated carbon plate, not only can efficient layered adsorption of precious metals and deep purification of wastewater be achieved, but also quick disassembly and assembly can be achieved through the sliding snap-fit ​​of the limiting frame and the protrusion, which significantly reduces the difficulty of equipment maintenance and downtime. At the same time, the filter plate of the pre-treatment water inlet component can effectively intercept large particulate impurities and effectively extend the service life of the activated carbon plate. Moreover, the modular design of the extension pipe structure supports multi-level thread splicing, and the water inlet position can be flexibly adjusted according to the actual working conditions to ensure that the wastewater and activated carbon are in full contact, further improving the adsorption efficiency and treatment effect.

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-6 As shown, this embodiment provides an activated carbon canister for automatically adsorbing precious metals, including a support leg 1 and a canister 2 placed on the ground. The outer side of the canister 2 is fixedly installed on the top of the support leg 1, and the support leg 1 provides support for the canister 2, improving the stability of the activated carbon canister during operation. A sealing cover 3 is installed at one end of the canister 2, which seals the canister 2 to prevent wastewater leakage. An inlet pipe 16 is fixedly installed through the sealing cover 3, and a pre-treatment inlet component 4 is threaded on the outer side of the inlet pipe 16. Multiple outlet pipes 5 are fixedly installed through the outer side of the canister 2, and a one-way valve is fixedly installed on the outer side of each outlet pipe 5. The one-way valve can prevent the wastewater in the canister 2 from flowing back, ensuring the smoothness of the wastewater treatment process. A first limiting frame 6 is fixedly installed on the inner wall of the canister 2, and a first filter frame 7 is fixedly installed on the inner side of the sealing cover 3. A first protrusion 8 is fixedly installed on the outer side of the first filter frame 7, and the first protrusion 8 is slidably engaged inside the first limiting frame 6.

[0017] Multiple sets of water outlet holes 9 are provided on the outer side of the first filter frame 7. A second filter frame 12 is provided inside the first filter frame 7. A first activated carbon plate 10 for adsorbing precious metals is provided inside the first filter frame 7. A second limiting frame 11 and a second protrusion 13 are respectively fixed on the inner side of the first filter frame 7 and the outer side of the second filter frame 12. The second protrusion 13 is slidably engaged inside the second limiting frame 11. Multiple sets of water outlet holes 14 are provided on the outer side of the second filter frame 12. A second activated carbon plate 15 for adsorbing precious metals is provided inside the second filter frame 12. Both the first activated carbon plate 10 and the second activated carbon plate 15 are made of coconut shell activated carbon with high specific surface area, which enables efficient adsorption of precious metals in wastewater.

[0018] In actual use, wastewater first enters the tank 2 through the pre-treatment inlet assembly 4. The pre-treatment inlet assembly 4 effectively intercepts large particulate impurities, preventing them from entering the tank 2 and clogging the activated carbon plates, thus extending the service life of the activated carbon plates. Subsequently, the pre-treated wastewater flows into the second filter frame 12 inside the tank 2. The second activated carbon plate 15 performs initial adsorption on the wastewater. The wastewater, after initial adsorption by the second activated carbon plate 15, flows out through the outlet hole 14 on the outside of the second filter frame 12 and enters the space between the first filter frame 7 and the second filter frame 12. At this time, the first activated carbon plate 10 performs secondary adsorption on the wastewater, further removing precious metal elements from the wastewater. The water outlet 9 on the outside of the frame 7 ensures that the wastewater after two adsorption treatments can be smoothly discharged to the water outlet pipe 5 outside the tank 2, ultimately achieving efficient stratified adsorption of precious metals and deep purification of wastewater. When maintenance or replacement of activated carbon plates is required, simply open the sealing cover 3 and slide the first protrusion 8 and the second protrusion 13 on the first limiting frame 6 and the second limiting frame 11 to quickly remove the first filter frame 7 and the second filter frame 12 from the tank 2 for replacement or cleaning of the activated carbon plates. This significantly reduces the difficulty of equipment maintenance and downtime, and improves the overall treatment efficiency. The double-layer filter frame structure and the coconut shell activated carbon plate with a high specific surface area achieve efficient stratified adsorption of precious metals and deep purification of wastewater.

[0019] As a technical optimization solution of this utility model, specifically as follows: Figure 6 As shown, the pre-treatment inlet assembly 4 includes a mounting bracket 401 and a connecting pipe 402. The mounting bracket 401 is threaded onto the outside of the inlet pipe 16, and the connecting pipe 402 is fixed inside the mounting bracket 401. A treatment box 403 is fixedly installed at one end of the connecting pipe 402. A filter plate 404 for pre-filtering wastewater is installed inside the treatment box 403. The arrangement of the treatment box 403 and the filter plate 404 enables preliminary filtration of the wastewater entering the tank 2, intercepting large particulate impurities in the wastewater, such as sand and debris, and avoiding... To prevent these impurities from entering the tank 2 and clogging the pores of the activated carbon plate, thus affecting the adsorption effect of the activated carbon plate on precious metals, the other end of the connecting pipe 402 is located inside the tank 2 and the inner wall of the other end of the connecting pipe 402 is provided with a threaded groove 405. An extension pipe 406 is provided at the other end of the connecting pipe 402. A threaded protrusion 407 is provided on the outer side of one end of the extension pipe 406. The extension pipe 406 is threadedly connected to the other end of the connecting pipe 402 through the threaded protrusion 407. A second threaded groove 408 is provided on the inner wall of the other end of the extension pipe 406.

[0020] In use, wastewater is initially filtered by the filter plate 404 in the treatment tank 403 and then flows into the tank 2 through the connecting pipe 402. The filter plate 404 can intercept large particles of impurities, preventing them from entering the tank 2 and clogging the activated carbon plate. When it is necessary to adjust the water inlet position to adapt to different working conditions, the extension pipe 406 can be rotated to separate its threaded protrusion 407 from the threaded groove 405 at the other end of the connecting pipe 402. The threaded protrusion 407 on its outer side is then threadedly connected to the threaded groove 408 on the inner wall of the connecting pipe 402 or another extension pipe 406, realizing multi-stage splicing. This allows for flexible adjustment of the water inlet depth, ensuring full contact between the wastewater and the activated carbon and improving adsorption efficiency. In addition, the pre-treatment water inlet assembly 4 is threadedly connected to the water inlet pipe 16 through the fixing bracket 401, which facilitates quick disassembly and assembly, and makes it convenient to clean the filter plate 404 regularly or replace damaged parts, further reducing the difficulty of equipment maintenance.
