Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and specifically provides a deep purification device for municipal wastewater effluent. Background Technology

[0002] To maintain a clean and hygienic urban environment, wastewater generated in cities needs to be treated to prevent pollution. Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] Patent CN 214829120 U discloses a deep purification device for urban sewage effluent, including a tank. A servo motor is mounted on the upper surface of the tank, and a threaded rod is fixedly connected to the output shaft of the servo motor. A threaded sleeve is threadedly connected to the outer wall of the threaded rod, and several connecting rods are fixedly connected to the outer wall of the threaded sleeve. Through the action of the servo motor and the cooperation of a slider and a sliding groove, the servo motor drives the threaded rod to rotate. The threaded sleeve allows a scraper plate to rise and fall, facilitating multi-directional cleaning of the inner wall of the tank and enabling rapid and effective removal of impurities. Simultaneously, by connecting water to an annular pipe, several inclined nozzles flush away impurities flowing to the bottom of the inner wall of the tank after cleaning, creating a vortex-like water flow to enhance the cleaning effect and effectively prevent impurities from affecting the purification of the effluent.

[0004] This application improves the deep purification device for wastewater effluent, which uses a scraper to lower the scraper to clean the inner wall of the tank from multiple angles, making it easy to remove impurities quickly and effectively. However, when purifying with this device, the dirt on the filter screen cannot be cleaned during the purification process; only the dirt on the side wall can be cleaned.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention filters wastewater using a vibration filtration mechanism. Wastewater is injected into a distribution pipe through an inlet pipe and then evenly sprayed onto both sides of a V-shaped filter plate through a flow pipe. A first motor is then activated, driving an elliptical vibration shaft and a guide channel via a first transmission belt. The rotating elliptical vibration shaft beats the V-shaped filter plate, thus filtering impurities from the wastewater. Simultaneously, a rotating worm gear transports the filtered impurities through a discharge port into a drainage trough. While the V-shaped filter plate is filtering wastewater, a hydraulic rod pushes a lifting frame downwards, and a scraper removes dirt adhering to the surface of the V-shaped filter plate. As the lifting frame moves downwards, a first connecting rod rotates to both sides, following the tilt angle of the V-shaped filter plate. When the lifting frame reaches its bottom and moves upwards, a pull rod pulls the first connecting rod back to the center, effectively scraping away dirt that is difficult to remove from the filter screen.

[0018] 2. This invention utilizes a secondary filtration mechanism to clean the dirt that has settled at the bottom of the sedimentation tank after being filtered by the vibration filtration mechanism. First, a second motor drives a third transmission wheel and a second transmission belt to rotate. A baffle plate fixed above the second connecting rod scrapes the dirt settled on the lower surface of the sedimentation tank onto the conveyor belt. Then, the dirt is carried to the top of an inclined plate by a dirt storage plate above the conveyor belt and falls into the filter collection tank. The water carried into the filter collection tank by the filter screen and water trough at the bottom of the filter collection tank is filtered back into the sedimentation tank, thus achieving a secondary filtration effect.

Detailed Implementation

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0030] like Figures 1-7 The municipal sewage treatment effluent deep purification device shown includes a sedimentation tank 1. The sedimentation tank 1 is equipped with a vibration filter mechanism 2 for filtering and purifying sewage. Above the vibration filter mechanism 2, a cleaning mechanism 3 is provided for cleaning the surface of the vibration filter mechanism 2. The side surface of the sedimentation tank 1 is equipped with a transmission mechanism 4 for providing power to the vibration filter mechanism 2. The inside side of the sedimentation tank 1 is equipped with a secondary filter mechanism 5 for performing three sedimentation and filtration of the water filtered by the vibration filter mechanism 2.

[0031] The vibration filtration mechanism 2 includes a V-shaped filter plate 201 fixedly connected inside the sedimentation tank 1, an elliptical vibration shaft 202 rotatably connected inside the sedimentation tank 1, a drain port 203 fixedly connected to the side surface of the sedimentation tank 1, a worm gear 204 rotatably connected inside the sedimentation tank 1, and a guide channel 205 fixedly connected inside the sedimentation tank 1. The transmission mechanism 4 includes a first rotating rod 401 rotatably connected inside the sedimentation tank 1, a first motor 402 fixedly connected to the side surface of the sedimentation tank 1, and a first... The outer surface of the transmission wheel 403 and the worm gear 204 is fixedly connected to the second transmission wheel 404. The outer surface of the second transmission wheel 404 is connected to the first transmission belt 405. The first rotating rod 401 is fixedly connected to the elliptical vibration shaft 202. The second transmission wheel 404, the first rotating rod 401, and the first transmission wheel 403 are connected by the first transmission belt 405. The inner side of the first transmission belt 405 is made of anti-slip material, and the second transmission wheel 404, the first rotating rod 401, the first transmission wheel 403 and the first transmission belt 405 cooperate with each other.

[0032] Furthermore, after the sewage is injected into the diversion pipe 313 through the inlet pipe 312, it is then evenly sprayed onto both sides of the V-shaped filter plate 201 through the set water pipe 314. Then, by starting the first motor 402, the set first transmission belt 405 drives the elliptical vibration shaft 202 and the guide groove 205 to rotate. The rotating elliptical vibration shaft 202 beats the V-shaped filter plate 201, thereby achieving the effect of filtering impurities in the sewage. At the same time, the rotating worm 204 transports the screened impurities through the sewage outlet 203 into the interior of the sewage tank 6, thereby achieving the effect of collection.

[0033] The cleaning mechanism 3 includes a hydraulic rod 301 fixedly connected inside the sedimentation tank 1. A lifting frame 302 is fixedly connected to the bottom end of the hydraulic rod 301. A first rotating shaft 303 is rotatably connected inside the lifting frame 302. A first connecting rod 304 is fixedly connected to the lower surface of the first rotating shaft 303. A scraper 305 is fixedly connected to the bottom end of the first connecting rod 304. A first gear 306 is fixedly connected to one end of the first rotating shaft 303. A second gear 307 is rotatably connected inside the first rotating shaft 303. A rotating wheel 308 is fixedly connected to the other end of the first rotating shaft 303. A pull rod 309 is fixedly connected to one side, and a tie rod 310 is fixedly connected to the outer surface of the pull rod 309. A fixing plate 311 is fixedly connected to the upper surface of the sedimentation tank 1. An inlet pipe 312 is provided inside the fixing plate 311. A diversion pipe 313 is fixedly connected to the bottom end of the inlet pipe 312. A flow pipe 314 is fixedly connected to the bottom end of the diversion pipe 313. A first gear 306 and a second gear 307 are meshed and connected. The flow pipe 314 is fixedly connected to the upper surface of the V-shaped filter plate 201. A guide channel 205 is fixedly connected to the bottom end of the V-shaped filter plate 201. A drain outlet 203 is connected to the guide channel 205.

[0034] Furthermore, when the V-shaped filter plate 201 filters sewage, the hydraulic rod 301 pushes the lifting frame 302 downward, and the scraper 305 can scrape off the dirt adhering to the surface of the V-shaped filter plate 201. As the lifting frame 302 moves downward, the first connecting rod 304 will flip to both sides according to the tilt angle of the V-shaped filter plate 201. When the lifting frame 302 moves to the bottom and moves upward, the pull rod 309 can pull the first connecting rod 304 to flip in the middle, thereby achieving the effect of scraping off the dirt that is difficult to shake off the filter screen.

[0035] The secondary filtration mechanism 5 includes a second motor 501 fixedly connected to the side surface of the sedimentation tank 1. A first drive shaft 504 is fixedly connected to the output shaft of the second motor 501. A third drive wheel 502 is fixedly connected to the outer surface of the first drive shaft 504. A second drive belt 503 is driven through the outer surface of the third drive wheel 502. A second connecting rod 505 is fixedly connected to the side surface of the second drive belt 503. A lever 506 is sleeved on the outer surface of the second connecting rod 505. A third motor 507 is fixedly connected to the side surface of the sedimentation tank 1. A second drive shaft 508 is fixedly connected to the output shaft of the third motor 507. A drive belt 506 is driven through the outer surface of the second drive shaft 508. The conveyor belt 509 has a second rotating shaft 510 rotatably connected inside the sedimentation tank 1. The conveyor belt 509 has a sludge storage plate 511 fixedly connected inside the sedimentation tank 1. The sedimentation tank 1 has an inclined plate 512 fixedly connected inside the sedimentation tank 1. The sedimentation tank 1 has a filter collection tank 513 slidably connected inside the sedimentation tank 1. The sedimentation tank 1 has a water flow tank 514. The sludge storage plate 511 is made of filter screen material. The second rotating shaft 510 is rotatably connected inside the conveyor belt 509. The second motor 501 and the third motor 507 are slow-speed motors. The bottom of the side surface of the sedimentation tank 1 is provided with a sludge discharge trough 6. The upper surface of the sedimentation tank 1 is fixedly connected with a closed shell 7. The lower surface of the sedimentation tank 1 is fixedly connected with a support leg 8.

[0036] Furthermore, the second motor 501 first drives the third transmission wheel 502 and the second transmission belt 503 to rotate. The dirt settled on the lower surface of the sedimentation tank 1 is scraped onto the conveyor belt 509 by the baffle plate 506 fixed above the second connecting rod 505. Then, the dirt is carried to the inclined plate 512 by the dirt storage plate 511 above the conveyor belt 509 and then falls into the filter collection tank 513. The water brought into the dirt inside the filter collection tank 513 is filtered into the sedimentation tank 1 by the filter screen and water trough 514 at the bottom of the filter collection tank 513, thereby achieving the effect of secondary filtration.

[0037] Working principle: When sewage is injected into the diversion pipe 313 through the inlet pipe 312, it is then evenly sprayed onto both sides of the V-shaped filter plate 201 through the flow pipe 314. The first motor 402 is then started, driving the elliptical vibration shaft 202 and the guide channel 205 to rotate via the first transmission belt 405. The rotating elliptical vibration shaft 202 beats the V-shaped filter plate 201, thus filtering impurities from the sewage. Simultaneously, the rotating worm gear 204 transports the filtered impurities through the drain port 203 into the sewage tank 6. While the V-shaped filter plate 201 is filtering the sewage, the hydraulic rod 301 pushes the lifting frame 302 downwards. The scraper 305 removes dirt adhering to the surface of the V-shaped filter plate 201. As the lifting frame 302 moves downwards, the first connecting rod 304 follows the tilt angle of the V-shaped filter plate 201. When the lifting frame 302 moves to the bottom and upwards, the pull rod 309 can pull the first connecting rod 304 to flip in the middle, thereby scraping off the dirt that is difficult to shake off the filter screen. After filtration, the wastewater continues to be stored in the sedimentation tank 1 for sedimentation. First, the second motor 501 drives the third transmission wheel 502 and the second transmission belt 503 to rotate. Then, the baffle plate 506 fixed above the second connecting rod 505 scrapes the dirt settled on the lower surface of the sedimentation tank 1 to the top of the conveyor belt 509. Then, the dirt is carried to the top of the inclined plate 512 by the dirt storage plate 511 above the conveyor belt 509 and then falls into the filter collection tank 513. The water brought into the dirt inside the filter collection tank 513 is filtered into the sedimentation tank 1 through the filter screen and the water flow tank 514 at the bottom of the filter collection tank 513, thereby achieving the effect of secondary filtration.
