Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and more specifically, to a wastewater filtration device. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment typically involves using a wastewater filtration system to filter and intercept solid particles, thus purifying the wastewater. However, in existing filtration devices, some of the filtered and intercepted particles remain on the filter screen. Over time, these residual particles can clog the filter screen's mesh, requiring operators to periodically remove and clean the screen. Once the filter screen is removed, the entire device becomes unusable, impacting wastewater treatment efficiency. Therefore, providing a filtration device that automatically cleans the filter screen is of significant importance. Utility Model Content

No manual intervention is required during the operation; only the waste collected internally needs to be collected later. Attached Figure Description

[0057] In practical applications, a pair of symmetrical water pumps 206 are fixedly connected inside the housing 201. The output end of the water pumps 206 is fixedly connected to a water outlet pipe 207. The end of the water outlet pipe 207 away from the water pumps 206 passes through the outer wall of the housing 201 and is connected to the separation device 4.

One end of the pusher arm 308 passes through the side walls of the housing 301 and the shell 201 and is connected to the scraper 309. The driving device is driven by the pusher arm to drive the pusher arm to reciprocate along the guide groove, thereby causing the scraper to scrape back and forth on the filter plate.

[0061] In practical applications, a guide block 307 is fixedly connected inside the housing 301. A push arm 308 is slidably connected to the rear end of the guide block 307. One end of the push arm 308 penetrates the outer wall of the housing 301 and extends into the interior of the outer shell 201, penetrating the right-side splash guard 202. The push arm 308 is slidably connected to the splash guard 202. A scraper 309 is fixedly connected to one end of the reciprocating arm 308. The top of the scraper 309 is in contact with the top of the filter plate 203. The wastewater is initially filtered through the filter assembly 2. During the filtration process, the push arm 308 drives the scraper 309 to reciprocate linearly, causing the scraper 309 to scrape away large particles intercepted on the filter plate 203, preventing the filter plate 203 from clogging.

[0062] Furthermore, the driving device includes a motor 302, a wheel 303, and a swing mechanism; the rotation shaft of the motor 302 is connected to the wheel 303, one end of the swing mechanism is slidably disposed on one side of the wheel, and the swing mechanism is drivenly connected to the push arm. When the motor rotates, the wheel drives the swing mechanism to swing, thereby driving the push arm to reciprocate.

[0063] Furthermore, the swing mechanism includes a swing arm 305 and a half-gear 306. One end of the swing arm 305 is rotatably connected to a rotating shaft 304, which passes through the upper and lower sides of the swing arm and is connected to the inner wall of the housing. The other end of the swing arm 305 has a sliding groove, within which a shaft is provided. The shaft passes through the upper and lower sides of the swing arm and is fixedly connected to the wheel. The shaft is eccentrically positioned with respect to the wheel and is slidably connected to the swing arm. The end of the swing arm away from the wheel is connected to the half-gear 306. The push arm has a protrusion adapted to the half-gear, and the half-gear meshes with the protrusion. When the wheel rotates, it drives the swing arm to swing around the rotating shaft, causing the half-gear to drive the push arm in reciprocating motion.

[0064] In practical applications, a motor 302 is fixedly connected inside the housing 301. A wheel 303 is fixedly connected to the transmission end of the motor 302. A swing arm 305 is slidably connected to the top of the wheel 303. A rotating shaft 304 is rotatably connected inside the swing arm 305. The rotating shaft 304 passes through the upper and lower ends of the swing arm 305 and is fixedly connected to the inner wall of the housing 301. The motor 302 drives the wheel 303 to rotate, and the wheel 303 drives the swing arm 305 to swing through the rotating shaft 304. A shaft is provided inside the swing arm 305 and behind the rotating shaft 304. The shaft passes through the upper and lower ends of the swing arm 305 and is fixedly connected to the wheel 303. The shaft and the wheel 303 are eccentrically arranged, and the shaft and the swing arm 305 are slidably connected. The eccentrically arranged shaft can cooperate with the wheel 303 to drive the swing arm 305 to swing. A half-gear 306 is fixedly connected to the end of the swing arm 305 away from the wheel 303. The half-gear 306 meshes with the push arm 308. The swing arm 305 drives the half-gear 306 to swing, and the half-gear 306 meshes with the push arm 308, thus the half-gear 306 drives the push arm 308 to move. A protrusion adapted to the half-gear 306 is fixedly connected to the rear end of the push arm 308. The protrusion meshes with the half-gear 306. The movement of the push arm 308 is facilitated by the cooperation between the protrusion and the half-gear 306.

[0065] Furthermore, the separation device includes: a separation chamber 401, a flow guide chamber 402, a protective box 403, a motor 407, a stirring rod 409, and a sedimentation box 404. The separation chamber 401 is connected to the outlet pipe 207. The top of the separation chamber 401 is fixedly connected to the flow guide chamber 402, and the top of the flow guide chamber 402 is fixedly connected to the protective box 403. The protective box 403 is connected to the housing 301. The separation chamber 401 has an inverted conical structure, and the bottom end of the separation chamber 401 is threadedly connected to the sedimentation box 404, which communicates with the inner cavity of the separation chamber 401. The protective box 403 houses the motor 407, and the drive end of the motor 407 is connected to a drive shaft 408. The end of the drive shaft 408 away from the motor passes through the bottom of the protective box and the flow guide chamber, extends into the interior of the separation chamber, and is fixedly connected to the stirring rod 409. The flow guide chamber 402 has multiple diversion pipes 406 inside. One end of each diversion pipe 406 extends through the bottom of the flow guide chamber into the interior of the separation chamber. A connecting pipe 405 is connected to the middle of the flow guide chamber, communicating with the inner cavity of the flow guide chamber to discharge filtered wastewater. When the motor rotates, it drives the stirring rod to rotate in the separation chamber, creating a vortex in the water and causing particulate impurities in the water to settle into the sedimentation box.

[0066] In practical applications, the separation device can employ multiple pairs of separation chambers. The cleaning process is as follows: First, wastewater is introduced into the outer shell 201 of the filter assembly 2. After being buffered by the splash guard 202, it falls onto the filter plate 203. At this time, the motor 302 inside the housing 301 is activated. The motor 302 drives the wheel 303 to rotate. Because the eccentrically mounted shaft on the wheel 303 is slidably connected to the swing arm 305, and the swing arm 305 is rotatably connected to the inner wall of the housing 301 via the rotating shaft 304, the rotation of the wheel 303... This causes the swing arm 305 to swing around the rotating shaft 304, and the half gear 306 at one end of the swing arm 305 swings accordingly. Because the half gear 306 meshes with the protrusion at the rear end of the push arm 308, and the push arm 308 is guided by the guide block 307, the swing of the half gear 306 will drive the push arm 308 to make reciprocating linear motion between the outer shell 201 and the housing 301. This will cause the scraper 309 fixed at one end of the push arm 308 to slide back and forth on the top of the filter plate 203, intercepting the filter plate 203. Large particles are scraped off and fall into the collection box 205 for easy subsequent processing, effectively preventing the filter plate 203 from clogging. Then, the water that has undergone preliminary filtration is transported to the separation chamber 401 of the separation device 4 through the water pipe 207 by the water pump 206 inside the outer shell 201. The motor 407 inside the protective box 403 starts, driving the drive shaft 408 to rotate. The drive shaft 408 drives the stirring rod 409 to rotate in the separation chamber 401. The stirring rod 409 creates a vortex in the water. Using the centrifugal force generated by the vortex, the particulate impurities in the water settle into the sedimentation box 404 threaded at the bottom of the separation chamber 401. The relatively clean water in the separation chamber 401 enters the guide chamber 402 through the diversion pipe 406 and is then discharged through the connecting pipe 405. This achieves the filtration and collection of larger impurities in the sewage and the separation of mud and metal particles. The whole process does not require much manual intervention. Only the garbage collected in the collection box 205 and sedimentation box 404 needs to be cleaned periodically.

[0067] The device also includes a controller (not shown in the figure); the controller is connected to the water pump, the motor and the motor signal respectively to control the operation or stop of the water pump, the motor and the motor.

[0068] Furthermore, the fixed support is a boss structure.

[0069] As can be seen, this utility model provides a sewage filtration device that cleans particulate matter on the filter screen of the filter assembly using a cleaning device, and then separates the impurities using a separation device. This solves the problem that existing filter devices require regular cleaning of the filter screen and cannot automatically clean the filter screen, which affects the sewage treatment efficiency. It can improve the efficiency of sewage treatment and increase the automation level of the filtration device.
