Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to an environmental engineering sewage purification device. Background Art

[0002] Sewage refers to polluted water discharged from daily life and production. Water that has lost its original function is simply called sewage. It is mainly water used in daily life. It contains a lot of organic matter and is relatively easy to treat. Based on the source of sewage, sewage can be defined as liquid or water discharged from residential, institutional, commercial, or industrial areas and mixed with groundwater, surface water, and blizzard water, carrying waste. Sewage treatment projects refer to projects that use various methods to separate pollutants contained in sewage or convert them into harmless substances, thereby purifying the sewage. In order to assist in the stable purification and treatment of environmental engineering sewage, an environmental engineering sewage purification device is required.

[0003] The utility model patent with prior art announcement number CN221579933U discloses an environmental engineering sewage purification device. By setting a baffle, the top of the treatment tank body can be protected to prevent birds from easily discharging feces into the interior of the treatment tank body during sedimentation. A first telescopic rod is set to drive the baffle to rise and fall slightly, thereby cleaning the filter. However, its disadvantage is that when cleaning the filter, even if the baffle can rise slightly, it still covers the top of the treatment tank body, which is still inconvenient to clean the filter. The baffle needs to be removed to achieve this, and the operation is slightly complicated. In addition, this existing technology can only purify sewage by sedimentation, and its function is single.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1 and Figure 4 As shown, the environmental engineering sewage purification device in this embodiment includes a purification tank 1, and the upper parts of the two opposite sides of the purification tank 1 are respectively provided with a water inlet and a water outlet. The upper part of the side of the purification tank 1 close to the water inlet is a filter chamber 2, and the side of the filter chamber 2 away from the water inlet is an adsorption chamber 19. The lower part of the purification tank 1 is an aeration chamber 3, which is connected to the filter chamber 2 and the adsorption chamber 19 respectively. Figure 1 、 Figure 2 As shown, a shielding curtain 4 is provided above the purification pool 1, and sliding rods 5 are fixedly provided above the opposite side walls of the purification pool 1. A plurality of connecting rings 6 are provided at equal intervals on the edge of the shielding curtain 4 near the sliding rod 5, two of which are provided at both ends of the shielding curtain 4, and the connecting ring 6 at one end is fixedly sleeved on the sliding rod 5, and the remaining connecting rings 6 are slidably sleeved on the sliding rod 5.

[0026] In this embodiment, a rack 7 is fixed to the outside of the slide bar 5, and the height of the rack 7 is lower than that of the slide bar 5. A mounting bracket 8 is provided on the outside of the rack 7, sliding along the length of the rack 7. Mounted on the mounting bracket 8 is a motor 9 and a gear 10 that meshes with the rack 7. The motor 9 is fixedly connected to the mounting bracket 8, and the gear 10 is fixed to the output shaft of the motor 9. A connecting ring 6 located at one end of the black curtain 4 and slidingly connected to the slide bar 5 is connected to the mounting bracket 8. This allows the motor 9 to drive the gear 10 to rotate while the mounting bracket 8 moves along the length of the rack 7, driving the black curtain 4 to expand or retract.

[0027] Specifically, in this embodiment, Figure 5 As shown, the teeth of the rack 7 are arranged upward, and slots 11 are provided on both sides of the rack 7 adjacent to the teeth along the length of the rack 7. The mounting frame 8 is an n-shaped plate, and sliders 12 are provided on the inner sides of the two wings of the n-shaped plate, which are compatible with the slots 11. The web of the n-shaped plate is located above the rack 7, and the gear 10 is located inside the n-shaped plate. The motor 9 and the connecting ring 6 are respectively located on either side of the outside of the n-shaped plate. The motor 9 and the connecting ring 6, which is located at one end of the screen curtain 4 and is slidably connected to the slide rod 5, are respectively connected to the two wings. The output shaft of the motor 9 rotates through the wings.

[0028] In this embodiment, if Figure 3 and Figure 4As shown, a first partition plate 20 is vertically disposed between the filter chamber 2 and the adsorption chamber 19. Two filter plates 13 are disposed within the filter chamber 2, with the water inlet located above the two filter plates 13. The two filter plates 13 are tilted in opposite directions, with filter mesh holes disposed only at the top of the filter plates 13, and the apertures of the filter mesh holes gradually decrease from top to bottom. By tilting the filter plates 13 and providing filter mesh holes only at the top, the apertures of the filter mesh holes gradually decrease from top to bottom, thereby facilitating the accumulation of filtered impurities at the bottom of the filter plates 13 without clogging the filter mesh holes.

[0029] In this embodiment, the edge of the filter screen is connected to the inner wall of the purification tank 1 and the first partition 20. A sewage outlet is provided on the side wall of the purification tank 1, located at the bottom of the filter plate 13. This outlet is connected to a first sewage pipe 14, which is equipped with a first sewage valve. A second partition 22 is positioned horizontally below the filter plate 13. This second partition 22 is lower than the first partition 20, forming a passage between the first and second partitions 20, 22, connecting the filter chamber 2 and the aeration chamber 3.

[0030] In this embodiment, an aeration pipe 15 is provided at the bottom of the aeration chamber 3. This pipe is connected to an air inlet pipe 16, which is in communication with an external air pump. This inlet pipe 16 is fixedly inserted through the side wall of the purification tank 1 and is sealed therewith. A mud guide plate 17 is provided below the aeration pipe 15. A second sewage pipe 18 is provided on the side wall of the purification tank 1, below the mud guide plate 17. A second sewage valve is provided on this second sewage pipe 18.

[0031] In this embodiment, an adsorption layer 21 is horizontally arranged in the adsorption chamber 19, and the water outlet is located above the adsorption layer 21. The adsorption layer 21 is connected to the inner wall of the clean water pool and the first partition 20. By setting the adsorption layer 21, the sewage needs to pass through the adsorption layer 21 before being discharged through the water outlet, so that the adsorption layer 21 is used to adsorb floating objects in the sewage, thereby further purifying the water quality. Specifically, the adsorption layer 21 can be in the form of a filter mesh wrapped around activated carbon, and the pore size of the filter mesh is smaller than the particle size of the activated carbon. Preferably, in actual use, the adsorption layer 21 is preferably installed in a detachable manner to facilitate replacement. The specific detachable installation method can be selected according to actual conditions, such as bolt connection, Velcro attachment, snap connection, etc. The blackout curtain 4 is preferably made of a light-blocking material.

[0032] In this embodiment, multiple water inlets are arranged at equal intervals in the horizontal direction, and each water inlet is provided with a water inlet branch pipe 23. The ends of all water inlet branch pipes 23 away from the water inlet are connected to the same water inlet main pipe 24. This embodiment adopts a dispersed water inlet method to facilitate filtration.

[0033] The working principle of the environmental engineering sewage purification device in this embodiment is:

[0034] By providing a filter chamber 2, an aeration chamber 3, and an adsorption chamber 19 within the purification tank 1, the sewage can be filtered, aerated, and adsorbed. The filtration process can filter out impurities in the sewage, and the aeration process can promote the activity of microorganisms and accelerate the oxidation and decomposition of organic matter. The adsorption layer 21 adsorbs floating objects and the like in the sewage, thereby purifying the sewage. By providing a shielding curtain 4 above the purification tank 1, and providing multiple connecting rings 6 on both sides of the shielding curtain 4 connected to the slide rod 5, similar to the structure of a curtain, when the connecting rings 6 are dispersed, the shielding curtain 4 completely covers the purification tank 1. Accumulating the connecting rings 6 to one side can expose the purification tank 1, thereby facilitating the cleaning of the filter chamber 2 and the like.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
