Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an activated carbon adsorption tower for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the process of separating, removing, recycling, or converting pollutants in wastewater into harmless substances using various technologies and methods, so that the wastewater meets the water quality requirements for discharge into a water body or for reuse. In the wastewater treatment process, activated carbon adsorption towers are needed, which are water treatment devices used to treat organic pollutants and odors in wastewater. They mainly remove impurities and pollutants from the water through the adsorption effect of activated carbon. However, current activated carbon adsorption towers still have the following shortcomings:

[0003] For example, patent document CN221440411U discloses an activated carbon adsorption tower for a wastewater treatment system. This activated carbon adsorption tower in a wastewater treatment system uses an electric actuator to move the adsorption plate to the desired height, then pauses the motor to facilitate worker replacement of the activated carbon. After replacement, the motor is restarted to lower the adsorption plate back into the tower and restore it to a completely fixed state. This device uses an electric actuator to replace manual removal of the adsorption plate, saving time and effort and improving work efficiency. However, it lacks a pre-filtration mechanism for wastewater. Larger particles and impurities in the wastewater can easily adversely affect the adsorption effect of the activated carbon adsorption mechanism, resulting in poor overall wastewater treatment performance.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed an activated carbon adsorption tower for wastewater treatment. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an activated carbon adsorption tower for wastewater treatment, comprising an adsorption tower body and a filter assembly. A drain valve is installed at the bottom right end of the adsorption tower body. The filter assembly is located at the top of the adsorption tower body and includes a support frame, a filter tank, a support ring, an intercepting mesh bag, a threaded sealing ring, a sealing cap, a cap handle, a water inlet, a connecting water valve, and a drain pipe. The support frame is located at the top left end of the adsorption tower body, and a filter tank is provided on the inner side of the upper end of the support frame. A support ring is engaged with the upper inner side of the filter tank, and an intercepting mesh bag is connected to the lower side of the support ring. The intercepting mesh bag and the support ring are a tightly connected integrated structure. A threaded sealing ring is threadedly connected to the upper inner surface of the filter tank.

[0007] Furthermore, a sealing cap is installed on the upper surface of the threaded sealing ring, and an opening handle is provided at both ends of the upper surface of the sealing cap. A water inlet is installed on the upper surface of the sealing cap.

[0008] Furthermore, a water valve is installed at the bottom of the filter tank, and a drain pipe is provided below the water valve.

[0009] Furthermore, the lower end of the drain pipe penetrates through the top of the adsorption tower and extends into the interior of the adsorption tower, and the interior of the adsorption tower is equipped with a disassembly and assembly component for easy cleaning.

[0010] Furthermore, the disassembly and assembly assembly includes a disassembly and assembly opening, a limiting slide groove, a limiting slide rail, a fixing frame, and an activated carbon adsorption block. The disassembly and assembly opening is located on the front side of the adsorption tower body. Limiting slide grooves are provided on both sides of the inner surface of the adsorption tower body. A limiting slide groove is slidably connected to the inner side of the limiting slide groove. A limiting slide rail is slidably connected to the inner side of the limiting slide groove. A fixing frame is installed on the outer surface of the limiting slide rail. An activated carbon adsorption block is provided inside the fixing frame.

[0011] Furthermore, the disassembly and assembly kit also includes a sealing plate, threaded fixing holes, a fixed threaded handle, and an auxiliary handle. A sealing plate is installed on the front side of the fixing frame. Threaded fixing holes are opened on both sides of the sealing plate and on both sides of the adsorption tower body. A fixed threaded handle is threadedly connected to the inside of the threaded fixing holes. The sealing plate is engaged with the inside of the disassembly and assembly opening. An auxiliary handle is installed on the front surface of the sealing plate.

[0012] Furthermore, the adsorption tower body is equipped with sealing baffles inside, and the sealing baffles are arranged alternately on the left and right sides.

[0013] Furthermore, four sets of sealing baffles are equidistant from top to bottom, and the sealing baffles are tightly connected to the inner surface of the adsorption tower.

[0014] This utility model provides an activated carbon adsorption tower for wastewater treatment, which has the following beneficial effects:

[0015] 1. This utility model incorporates a filtration assembly, including a support frame, a filter tank, a support ring, an intercepting mesh bag, a threaded sealing ring, a sealing cap, a handle, a water inlet, a connecting water valve, and a drain pipe. In use, wastewater is fed into the filter tank through the water inlet. As the wastewater passes through the intercepting mesh bag inside the filter tank, larger impurities are intercepted and filtered. The connecting water valve is opened, allowing the filtered wastewater to enter the adsorption tower through the drain pipe. After filtration, the sealing cap is opened by rotating the handle, allowing the support ring and intercepting mesh bag to be removed and cleaned. After cleaning, the intercepting mesh bag is fixed inside the filter tank by the engaging connection between the support ring and the inside of the filter tank. The threaded sealing ring engages with the inner surface of the filter tank, sealing the filter tank. This allows the device to pre-filter wastewater, preventing impurities in the wastewater from clogging the activated carbon adsorption structure and thus improving the wastewater adsorption treatment effect.

[0016] 2. This utility model incorporates a disassembly and assembly component, which includes a disassembly and assembly opening, a limiting slide groove, a limiting slide rail, a fixing frame, and an activated carbon adsorption block. The component also includes a sealing plate, a threaded fixing hole, a fixing threaded handle, and an auxiliary handle. In use, the fixing threaded handle is rotated to remove the fixed carbon adsorption block, and the sealing plate is pulled by the auxiliary handle. This causes the sealing plate to move the fixing frame forward, which in turn moves the activated carbon adsorption block out. The fixing frame is slidably connected to the inner side of the limiting slide groove via the limiting slide rail, achieving a certain limiting position. This allows the activated carbon adsorption block to be easily cleaned or replaced, thus maintaining the adsorption effect of the device. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4 As shown, an activated carbon adsorption tower for wastewater treatment includes an adsorption tower body 1 and a filter assembly 3. A drain valve 2 is installed at the bottom right end of the adsorption tower body 1. The filter assembly 3 is located at the top of the adsorption tower body 1 and includes a support frame 301, a filter tank 302, a support ring 303, an intercepting mesh bag 304, a threaded sealing ring 305, a sealing cover 306, a cover handle 307, a water inlet 308, a connecting water valve 309, and a drain pipe 310. The support frame 301 is located at the top left end of the adsorption tower body 1, and a filter tank 302 is provided on the inner side of the upper end of the support frame 301. The support ring 303 is snapped onto the upper inner side of the filter tank 302, and an intercepting mesh bag 304 is connected to the lower side of the support ring 303. The intercepting mesh bag 304 and the support ring 303 are an integrated structure that is tightly connected. A threaded sealing ring 305 is threaded onto the upper inner surface of the filter tank 302.

[0024] The specific operation is as follows: During use, sewage is transported to the filter tank 302 through the inlet 308. When the sewage passes through the intercepting net bag 304 inside the filter tank 302, larger impurities in the water will be intercepted and filtered by the intercepting net bag 304. Open the connecting water valve 309 to allow the filtered sewage to enter the adsorption tower 1 through the drain pipe 310. After the sewage is filtered, rotate the sealing cover 306 through the opening handle 307 to open the sealing cover 306, take out the support ring 303 and the intercepting net bag 304, and clean the impurities. After cleaning, the intercepting net bag 304 is fixed inside the filter tank 302 by the snap-fit ​​connection between the support ring 303 and the inside of the filter tank 302. The sealing cover 306 seals the filter tank 302 by the snap-fit ​​connection between the threaded sealing ring 305 and the inner surface of the filter tank 302.

[0025] Please refer to Figures 3 to 4A sealing cover 306 is installed on the upper surface of the threaded sealing ring 305, and opening handles 307 are provided at both ends of the upper surface of the sealing cover 306. A water inlet 308 is installed on the upper surface of the sealing cover 306. A connecting water valve 309 is installed at the bottom of the filter tank 302, and a drain pipe 310 is provided below the connecting water valve 309. The lower end of the drain pipe 310 passes through the top of the adsorption tower body 1 and extends into the interior of the adsorption tower body 1. A disassembly assembly 4 for easy cleaning is provided inside the adsorption tower body 1. The disassembly assembly 4 includes a disassembly opening 401, a limiting slide groove 402, a limiting slide rail 403, a fixing frame 404, and an activated carbon adsorption block 405. The disassembly opening 401 is opened on the front side of the adsorption tower body 1. Limiting slide grooves 402 are opened on both sides of the inner surface of the adsorption tower body 1, and the inner side of the limiting slide groove 402 is slidably connected to the inner side of the limiting slide groove 402. The system includes a limiting slide rail 403, with a fixing frame 404 installed on the outer surface of the limiting slide rail 403. An activated carbon adsorption block 405 is installed inside the fixing frame 404. The disassembly and assembly assembly 4 also includes a sealing plate 406, a threaded fixing hole 407, a fixing threaded handle 408, and an auxiliary handle 409. A sealing plate 406 is installed on the front side of the fixing frame 404. Threaded fixing holes 407 are opened on both sides of the sealing plate 406 and on both sides of the adsorption tower body 1. A fixing threaded handle 408 is threadedly connected to the inner side of the threaded fixing hole 407. The sealing plate 406 is engaged with the inner side of the disassembly and assembly opening 401. An auxiliary handle 409 is installed on the front surface of the sealing plate 406. A sealing baffle 5 is installed inside the adsorption tower body 1. The sealing baffle 5 is staggered on the left and right sides. Four sets of sealing baffle 5 are equally spaced from top to bottom. The sealing baffle 5 is tightly connected to the inner surface of the adsorption tower body 1.

[0026] The specific operation is as follows: During use, due to the obstruction of the sealing baffle 5, the sewage will flow around the sealing baffle 5, thereby prolonging the contact time between the sewage and the activated carbon and improving the treatment efficiency. After the sewage treatment is completed, open the drain valve 2 to discharge the water. Rotate to remove the fixed threaded handle 408, and pull the sealing plate 406 through the auxiliary handle 409, so that the sealing plate 406 drives the fixed frame 404 to move forward. The fixed frame 404 drives the activated carbon adsorption block 405 to move out, so as to clean or replace the activated carbon adsorption block 405 to maintain the adsorption effect of the device. The fixed frame 404 is slidably connected to the inner side of the limiting slide groove 402 through the limiting slide rail 403 to achieve a certain limit.

[0027] In summary, as Figures 1 to 4As shown, this activated carbon adsorption tower for wastewater treatment operates as follows: First, wastewater is fed into the filter tank 302 through the inlet 308. As the wastewater passes through the intercepting mesh bag 304 inside the filter tank 302, larger impurities in the water are intercepted and filtered. The connecting water valve 309 is then opened, allowing the filtered wastewater to enter the adsorption tower body 1 through the drain pipe 310. After filtration, the sealing cover 306 is opened by rotating the cover handle 307, allowing the support ring 303 and the intercepting mesh bag 304 to be removed and cleaned. After cleaning, the intercepting mesh bag 304 is fixed inside the filter tank 302 by the engaging connection between the support ring 303 and the filter tank 302. Finally, the filter tank is secured by a threaded sealing ring 305. The snap-fit ​​connection on the inner surface of 302 allows the sealing cover 306 to seal the filter tank 302. Subsequently, due to the obstruction of the sealing baffle 5, the sewage will flow around the sealing baffle 5, thereby prolonging the contact time between the sewage and the activated carbon and improving the treatment efficiency. After the sewage treatment is completed, the drain valve 2 is opened to drain the water. The fixed thread handle 408 is rotated and removed, and the sealing plate 406 is pulled by the auxiliary handle 409, so that the sealing plate 406 drives the fixed frame 404 to move forward. The fixed frame 404 drives the activated carbon adsorption block 405 to move out, so as to facilitate the cleaning or replacement of the activated carbon adsorption block 405 to maintain the adsorption effect of the device. The fixed frame 404 is slidably connected to the inner side of the limiting slide groove 402 through the limiting slide rail 403 to achieve a certain limiting.
