Description

Technical Field

[0001] The utility model relates to the technical field of water purification pools, in particular to an environmentally friendly sewage water purification pool. Background Art

[0002] Wastewater treatment is the process of purifying water that is discharged into a water body or reused. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. Wastewater treatment is generally divided into industrial wastewater treatment and domestic wastewater treatment. The water purification pools for sewage treatment include filtration pools and sedimentation pools.

[0003] When the existing water purification pool is settling sewage, impurities in the sewage will settle and clog the drain outlet of the water purification pool. The clogged drain outlet can easily affect the drainage efficiency of the water purification pool. At the same time, it is inconvenient for users to clean the drain outlet, thereby reducing the use effect of the water purification pool.

[0004] In the patent document with the announcement number CN217988644U, a water purification pool for circulating sewage treatment is disclosed, which filters and prevents the top of the drain pipe by setting a filter ring and cooperating with a connecting anti-blocking component, and then starts the connecting transmission component through the control box to make the connecting transmission component cooperate with the connecting anti-blocking component to perform transmission anti-blocking. This solves the problem that when the existing water purification pool precipitates sewage, impurities in the sewage will be precipitated and blocked in the drain outlet of the water purification pool. The blockage of the drain outlet is likely to affect the drainage efficiency of the water purification pool. At the same time, it is inconvenient for the user to clean the drain outlet, thereby reducing the use effect of the water purification pool, and achieving the effect of anti-blocking and cleaning.

[0005] However, when the water purification pool for circulating sewage treatment is used, there is no filtration on the water inlet side, which may allow large amounts of debris to enter the water purification pool and affect the water purification efficiency. In addition, the filter cartridge arranged at the water outlet can prevent the outlet pipe from being blocked, but cannot prevent precipitation from occurring inside the water purification pool. Therefore, it is necessary to propose an environmentally friendly sewage water purification pool. Utility Model Content

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.

[0026] See also Figures 1-6 , the utility model provides a technical solution: Example

[0027] An environmentally friendly sewage water purification pool comprises a water purification pool 1, a top plate 2 and a mounting plate 3 fixedly connected to the top of the water purification pool 1, and a second filtering mechanism is provided at the bottom of the mounting plate 3;

[0028] The second filtering mechanism includes a motor 301, a rotating shaft 302, a filter cartridge 303, a three-leaf push plate 304, a water outlet pipe 305, a side plate 306, a guide rod 307, a return spring 308, and a scraper plate 309. The motor 301 is mounted on the top of the mounting plate 3. The rotating shaft 302 is rotatably connected to the bottom of the mounting plate 3. The output end of the motor 301 is connected to the top of the rotating shaft 302. When the motor 301 is started, it drives the rotating shaft 302 to rotate, thereby driving the filter cartridge 303 and the three-leaf push plate 304 to rotate. The filter cartridge 303 is fixedly connected to the bottom of the rotating shaft 302, and the three-leaf push plate 304 is fixedly connected to the outer surface of the bottom of the filter cartridge 303. The water outlet pipe 305 is mounted on the bottom of the inner wall of the water purification tank 1, with the top of the water outlet pipe 305 higher than the bottom of the inner wall of the water purification tank 1. This arrangement can help the filter cartridge 303 cover the water outlet pipe 305, preventing the water outlet pipe 305 from being blocked. A side plate 306 is mounted at the bottom of the inner wall of the water purification tank 1. A guide rod 307 is fixedly connected to one side of the side plate 306. A return spring 308 is movably connected to the exterior of the guide rod 307. A scraper plate 309 is movably connected to the exterior of the guide rod 307. The scraper plate 309 is divided into two parts: one part comprises three scrapers spaced evenly apart, and the other part comprises stop posts. The stop posts are fixedly connected to both sides of the scrapers. One side of the stop post has a through hole that mates with the guide rod 307, limiting the position of the scraper plates 309. After sewage enters the water purification tank 1 and is purified, it is discharged from the water purification tank 1 through the outlet pipe 305. The motor 301 drives the rotating shaft 302 to rotate, which in turn rotates the filter cartridge 303, performing a final filtration on the discharged purified water and preventing silt from clogging the outlet pipe 305.

[0029] During the rotation of the filter drum 303, the three-leaf push plate 304 will be driven to rotate, and the return spring 308 in the compressed state will generate a rebound force under the action of its restoring force to act on one side of the scraper plate 309, so that the other side of the scraper plate 309 is always close to the three-leaf push plate 304, and the three-leaf push plate 304 will continuously apply thrust to the scraper plate 309 during the rotation process, so that the scraper plate 309 reciprocates in the direction of the guide rod 307 with a certain amplitude, thereby achieving the effect of scraping the bottom of the inner wall of the clean water pool 1, and effectively preventing the formation of sediment. Example

[0030] Based on the first embodiment, a first filtering mechanism is provided on top of the top plate 2. The first filtering mechanism includes a support rod 201, a filter tank 202, a filter sleeve 203, a connecting pipe 204, and a filter cup 205. The support rod 201 is fixedly connected to the top of the top plate 2, the filter tank 202 is fixedly connected to the top of the support rod 201, and the filter sleeve 203 is disposed on top of the filter tank 202. A portion of the filter sleeve 203 is configured as a semicircular filter plate positioned within the filter tank 202, while another portion is configured as a retaining plate positioned at the top of the filter tank 202 to retain the filter sleeve 203. The filter sleeve 203 can be removed by pulling a handle on its top. The connecting pipe 204 is disposed between the top plate 2 and the filter tank 202, and the filter cup 205 is disposed at the bottom of the top plate 2. An L-shaped protrusion is fixedly connected to the bottom of the top plate 2, which is configured to retain the filter cup 205. The filter cup 205 is located at the bottom of the connecting pipe 204, allowing wastewater passing through the connecting pipe 204 to be reprocessed. After being discharged into the filter tank 202, it is filtered through the filter sleeve 203 to screen out large waste in the sewage. Then the sewage is discharged into the water purification tank 1 through the connecting pipe 204, and the smaller waste is filtered out through the filter cup 205. The filter sleeve 203 and the filter cup 205 are set to be detachable, and the filtered debris can be cleaned regularly.

[0031] Working principle:

[0032] First, through the first filtering mechanism, the sewage is discharged into the filter tank 202, and is initially filtered through the filter sleeve 203 to screen out large wastes in the sewage. Then, the sewage is discharged to the inside of the clean water tank 1 through the connecting pipe 204, and some smaller wastes are filtered out through the filter cup 205. The filter sleeve 203 and the filter cup 205 are set to be detachable, and the filtered debris can be cleaned regularly. The sewage is pretreated before entering the clean water tank 1, which is beneficial to the subsequent purification of the sewage and improves the purification efficiency.

[0033] Furthermore, through the second filtering mechanism, after the sewage enters the water purification tank 1 and is purified, it will be discharged from the outside of the water purification tank 1 through the outlet pipe 305, and the starting motor 301 can drive the rotating shaft 302 to rotate, and then drive the filter cartridge 303 to rotate, and perform the final filtration on the discharged purified water, so that the purified water can be discharged after meeting the standards.

[0034] Furthermore, during the rotation of the filter drum 303, the three-leaf push plate 304 will be driven to rotate, and the return spring 308 in a compressed state will generate a rebound force under the action of its restoring force. The rebound force acts on one side of the scraper plate 309, so that the other side of the scraper plate 309 is always close to the three-leaf push plate 304. During the rotation process, the three-leaf push plate 304 will continuously apply thrust to the scraper plate 309, so that the scraper plate 309 reciprocates in the direction of the guide rod 307 with a certain amplitude, thereby achieving the effect of scraping the bottom of the inner wall of the clean water pool 1, effectively preventing the formation of precipitation, and the side plate 306 is detachable and can be removed for cleaning.
