Description

Technical Field

[0001] This utility model is a wastewater treatment filtration and adsorption device, belonging to the field of wastewater treatment. Background Technology

[0002] Activated carbon possesses a rich porous structure and a large specific surface area, exhibiting excellent adsorption performance for dissolved organic matter, heavy metal ions, and color in wastewater. Granular activated carbon is filled in equipment such as activated carbon tanks, where pollutants are adsorbed as wastewater passes through. Activated carbon tanks are crucial treatment equipment in wastewater treatment processes, with their inlet and outlet pipes typically mounted on the tank body using flanges and bolts. This connection method facilitates pipe installation and disassembly, as well as equipment maintenance and repair. Similarly, the ends of the inlet and outlet pipes furthest from the activated carbon tank are also connected to the delivery pipeline using flanges and bolts, thus constructing the entire wastewater transport and treatment pipeline system.

[0003] However, a significant problem exists in actual operation. When the seal between two interconnected flanges fails, water pressure causes it to spray out from the gaps between the flanges, splashing into the surrounding environment. This splashed wastewater not only wets the surrounding ground and equipment but may also carry impurities and odors, severely impacting the cleanliness of the environment and causing it to become dirty and unsanitary. This not only affects the aesthetics of the workplace but may also negatively impact the hygiene of surrounding equipment and the environment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sewage treatment filtration and adsorption device to solve the problems mentioned in the background art. This utility model prevents sewage splashing at the flange due to sealing failure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment filtration and adsorption device, comprising an activated carbon tank, a detachable top cover mounted on the top of the activated carbon tank, an outlet pipe mounted on the bottom of the activated carbon tank via a flange and bolts, an inlet pipe mounted on the upper surface of the top cover via a flange and bolts, the end of the inlet pipe away from the top cover extending to the side of the activated carbon tank, two electric valves mounted on the end of the inlet pipe away from the top cover via a T-junction, and flanged pipe fittings mounted on the ends of the electric valves away from the T-junction. The tank has a water collection tray at the top, and a drain pipe is installed at the bottom of the water collection tray. A U-shaped cover is fitted on the end of the inlet pipe away from the activated carbon tank, and both ends of the U-shaped cover are connected to the water collection tray. A lower water baffle is fitted on the end of the outlet pipe near the activated carbon tank, and the lower water baffle is connected and fixed to the U-shaped cover. A water baffle is fitted on the end of the inlet pipe near the electric valve and is connected and fixed to the inlet pipe. The electric valve and pipe joint are all located inside the water baffle. The bottom of the water baffle and the side of the water baffle facing the activated carbon tank are open. An upper water baffle is fitted on the end of the inlet pipe near the top cover and is connected to the inlet pipe.

[0006] Furthermore, a sponge pad is installed inside the U-shaped cover via Velcro, and the sponge pad has a U-shaped structure.

[0007] Furthermore, a sponge ring is installed inside the upper water-blocking ring via Velcro, and the inner diameter of the sponge ring is larger than the outer diameter of the flange installed near the top cover end of the liquid inlet pipe.

[0008] Furthermore, the lower outer surface of the activated carbon tank is provided with multiple support legs installed in a ring at equal intervals. The support legs pass through the water collection tray, and the lower end of the support legs is connected to and fixed to a base. The upper surface of the base is provided with multiple fixing holes evenly distributed.

[0009] Furthermore, an inspection port is installed on the lower outer surface of the activated carbon tank, and a blind plate is hinged to the inspection port. The blind plate is connected to the inspection port by multiple bolts. The inspection port is located directly above the water collection tray, and the range of motion of the blind plate is directly above the water collection tray.

[0010] Furthermore, two lifting lugs are symmetrically installed on the top of the activated carbon canister, and a round hole is provided on the upper part of one side of each lifting lug.

[0011] Furthermore, a connecting plate is fixedly connected to the outer surface of the lower water baffle ring, and the end of the connecting plate away from the lower water baffle ring is fixedly connected to the U-shaped cover.

[0012] Furthermore, an L-shaped plate is installed on the outer surface of the upper water baffle, and the vertical part of the L-shaped plate is connected and fixed to the liquid inlet pipe.

[0013] The beneficial effects of this utility model are:

[0014] 1. A multi-layered anti-splash structure is constructed by incorporating components such as a U-shaped cover, a lower water-retaining ring, a water-retaining shield, and an upper water-retaining ring. The U-shaped cover connects to a collection tray to collect wastewater that may splash from the flange at the end of the inlet pipe away from the activated carbon tank; the lower water-retaining ring prevents wastewater from splashing from the flange at the end of the outlet pipe near the activated carbon tank; the water-retaining shield covers the electric valve and pipe joints to prevent wastewater from splashing out from these areas; and the upper water-retaining ring blocks wastewater from the inlet pipe near the top cover. Leaking wastewater is contained and flows into the collection tray, then flows through the drain pipe and sewage pipe into the collection container, achieving the purpose of drainage. This helps maintain a clean working environment.

[0015] 2. By installing sponge pads inside the U-shaped cover and sponge rings inside the upper water-retaining ring, the sponge pads and sponge rings act as buffers when sewage impacts the U-shaped cover or the upper water-retaining ring under water pressure, preventing sewage from splashing again onto the inner wall of the U-shaped cover or the upper water-retaining ring. Because the lower water-retaining ring is arranged vertically, the activated carbon tank and the water collection tray limit the range of sewage splashing. Sewage splashing into the water-retaining cover flows downward into the water collection tray under the restriction of the water-retaining cover. Attached Figure Description

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1-4 This utility model provides a technical solution: a sewage treatment filtration and adsorption device, including an activated carbon tank 1, a detachable top cover 15 installed on the top of the activated carbon tank 1, two lifting lugs 16 symmetrically installed on the top of the activated carbon tank 1, a circular hole opened on the upper part of one side of the lifting lug 16, and multiple support legs 6 are installed in a ring at equal intervals on the lower outer surface of the activated carbon tank 1. The support legs 6 pass through the water collection tray 5, and a base 7 is fixedly connected to the lower end of the support legs 6. Multiple fixing holes are evenly opened on the upper surface of the base 7. The multiple support legs 6 achieve balanced support for the activated carbon tank 1. The base 7 is installed at the required position using bolts to limit the position of the activated carbon tank 1.

[0026] See Figure 3 The bottom of the activated carbon tank 1 is equipped with an outlet pipe 8 by means of flange and bolt. The top cover 15 is equipped with an inlet pipe 13 by means of flange and bolt. The end of the inlet pipe 13 away from the top cover 15 extends to the side of the activated carbon tank 1. The end of the inlet pipe 13 away from the top cover 15 is equipped with two electric valves 17 by means of a three-way pipe. The end of the electric valve 17 away from the three-way pipe is equipped with a pipe joint 18 with a flange. The two electric valves 17 are alternately controlled to open and close, so that the two inlet pipes can alternately deliver sewage into the activated carbon tank 1.

[0027] See Figures 1-6The activated carbon tank 1 has a water collection tray 5 on top, and a drain pipe 4 is installed at the bottom of the water collection tray 5. A U-shaped cover 10 is fitted onto the end of the inlet pipe 13 furthest from the activated carbon tank 1. Both ends of the U-shaped cover 10 are connected to the water collection tray 5. A lower baffle ring 21 is fitted onto the end of the outlet pipe 8 closest to the activated carbon tank 1. A connecting plate 11 is fixedly connected to the outer surface of the lower baffle ring 21. The end of the connecting plate 11 furthest from the lower baffle ring 21 is connected and fixedly connected to the U-shaped cover 10. The connecting plate 11 serves to connect the lower baffle ring 21 and the U-shaped cover 10. A baffle 1 is fitted onto the end of the inlet pipe 13 closest to the electric valve 17 and is fixedly connected to the inlet pipe 13. 2. The electric valve 17 and pipe connector 18 are both installed inside the water baffle 12. The bottom of the water baffle 12 and the side of the water baffle 12 facing the activated carbon tank 1 are both open. The end of the liquid inlet pipe 13 near the top cover 15 is fitted with an upper water baffle ring 14 connected to the liquid inlet pipe 13. An L-shaped plate 20 is installed on the outer surface of the upper water baffle ring 14. The vertical part of the L-shaped plate 20 is connected and fixed to the liquid inlet pipe 13. In order to effectively solve the problem of dirty and messy working environment caused by sewage splashing, a multi-layer anti-splash structure is designed, which is composed of U-shaped cover 10, lower water baffle ring 21, water baffle 12 and upper water baffle ring 14. Among them, U-shaped cover 10 plays a key collection role. Its two ends are connected to the water collection tray 5, which can effectively receive sewage that may be sprayed from the flange of the end of the liquid inlet pipe 13 away from the activated carbon tank 1. At this location, the inlet pipe 13 is connected to an external infusion pipeline. If the flange seal fails, sewage is highly likely to splash. The U-shaped cover 10 acts as a "protective umbrella," collecting this sewage. The lower baffle ring 21 is installed at the end of the outlet pipe 8 near the activated carbon tank 1. It effectively prevents sewage from splashing out when the flange seal fails, preventing sewage from directly spreading into the surrounding environment. The baffle cover 12 completely covers the electric valve 17 and the pipe joint 18, providing protection for these two areas prone to sewage leakage. During operation, the electric valve 17 and the pipe joint 18 may also cause sewage to splash out for various reasons. The presence of the baffle cover 12 confines the sewage within the cover, preventing pollution to the surrounding area. The upper baffle ring 14 is installed at the end of the inlet pipe 13 near the top cover 15, mainly used to block sewage that may leak from this location. When sewage leaks, these carefully designed components come into play. Splashed or leaked sewage is blocked by the corresponding components and eventually flows into the collection tray 5. The bottom of the collection tray 5 is connected to the drain pipe 4. Wastewater flows into the sewage pipe along the drain pipe 4 and is then transported to the collection container. Through this complete process, the leakage of wastewater is effectively diverted, greatly reducing the pollution of the working environment and effectively maintaining the cleanliness of the working environment.

[0028] See Figure 1 , Figures 3-6A sponge pad 9 with a U-shaped structure is installed inside the U-shaped cover 10 via Velcro. A sponge ring 19 with a U-shaped structure is installed inside the upper baffle ring 14 via Velcro. The inner diameter of the sponge ring 19 is larger than the outer diameter of the flange installed on the end of the inlet pipe 13 near the top cover 15. Sponge pads 9 and sponge rings 19 are installed inside the U-shaped cover 10 and the upper baffle ring 14, respectively. When sewage impacts the U-shaped cover 10 or the upper baffle ring 14 at high speed under water pressure, the sponge pads 9 and sponge rings 19 provide excellent cushioning. They act like soft "shields," effectively mitigating the impact force of the sewage and greatly reducing the possibility of sewage splashing out again after hitting the inner wall of the U-shaped cover 10 or the upper baffle ring 14, thus more effectively controlling the spread of sewage. Furthermore, the unique positioning design of the lower baffle ring 21 also plays an important role, working in conjunction with the activated carbon tank 1 and the collection tray 5 to effectively limit the range of sewage splashing. If wastewater splashes into the baffle 12, its special structure will restrict the wastewater to flow downwards, eventually flowing smoothly into the collection basin 5. In this way, whether it is splashed wastewater from various connection parts or wastewater rebounding due to impact, it can be guided in an orderly manner to the collection basin 5 through these carefully designed structures, and then discharged through the drain pipe 4, ensuring the cleanliness of the working environment in all aspects.

[0029] See Figures 1-3 An inspection port 2 is installed on the lower outer surface of the activated carbon tank 1. A blind flange 3 is hinged to the inspection port 2. The blind flange 3 is connected to the inspection port 2 by multiple bolts. The inspection port 2 is located directly above the water collection tray 5. The range of motion of the blind flange 3 is directly above the water collection tray 5. When the blind flange 3 is opened, the sewage dripping from the surface of the blind flange 3 or the sewage flowing out from the inspection port 2 drips into the water collection tray 5 under its own gravity, improving the effect of collecting dripping sewage.
