DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Embodiment 1: Figures 1 to 6As shown, a circulating sewage treatment device comprises a filtering mechanism 1, a water inlet pipe 101 is plugged into one side of the filtering mechanism 1, a water outlet pipe 102 is plugged into the other side of the filtering mechanism 1, the other end of the water outlet pipe 102 is plugged into the top of the water storage tank 2, and a water quality detector 103 is plugged into the bottom of the water outlet pipe 102; the water quality can be seen from the display screen on the water quality detector 103, a pressurized flushing device 3 is fixedly connected to the bottom of one side of the water storage tank 2, a circulating reflux device 4 is plugged into the bottom of the other side of the water storage tank 2, a main filter screen 6 is rotatably connected to one side of the filtering mechanism 1, an auxiliary filter screen 7 is fixedly connected to the other side of the filtering mechanism 1, and a gear rotating device 5 is fixedly connected to one side of the main filter screen 6; when the user uses the device, the sewage will The sewage enters the filter mechanism 1 through the water inlet pipe 101, and the large particles of impurities are first filtered out through the main filter 6, and then the small particles of impurities are filtered out through the auxiliary filter 7, and then the sewage enters the water storage tank 2 through the outlet pipe 102. Before the sewage enters the water storage tank 2, the sewage passes through the water quality detector 103 in the outlet pipe 102. The water quality can be seen from the display screen on the water quality detector 103. After the sewage enters the water storage tank 2, the water level can be seen through the observation port 201, and the entry and suspension of the sewage can be controlled. Then, the treated sewage that still does not meet the water quality standards is flowed to the filter element 403 through the pressure pump 402 for treatment, and then enters the filter mechanism 1 through the return pipe 401 for filtration again, and the cycle is repeated until the water quality is qualified;

[0031] like Figure 2 , Figure 5 and Figure 6As shown, the pressurized flushing device 3 includes a flushing pipe 301, which is plugged into one side of the water tank 2, and the other end of the flushing pipe 301 is fixedly connected to a water pump 302, and the other end of the water pump 302 is fixedly connected to a nozzle 303, and the nozzle 303 is rotatably connected to a guide plate 304 inside, and a torsion spring is provided at the rotating position, and the side of the end of the guide plate 304 close to the main filter 6 is fixedly connected to a water pocket plate 305, and a plurality of leakage holes 306 are penetrated through the side of the water pocket plate 305 close to the main filter 6; when the device has been working for a period of time, the filter screen will be clogged with impurities, and the water pump 302 will pump the water in the water tank 2 to the nozzle 303 to make it continue to work, and the recoil force of the water flow will spray the impurities from the main filter 6, so that the main filter 6 can continue to work. The operation greatly improves the work efficiency and reduces the time of manual processing. Since the main filter screen 6 at the bottom has the most and largest blockages, a guide plate 304 that can rotate due to water pressure impact is provided inside the nozzle 303. When the water pumped into the nozzle 303 hits the guide plate 304, one end of the guide plate 304 has a water retaining plate 305. Therefore, the water flow hits the water retaining plate 305, so that the guide plate 304 is opened through the nozzle. When the water flows out, the water flows out from the gap between the guide plate 304 and the nozzle 303 and the leak hole 306. The initial water flow has a large impact force, and then rotates to the water flow at the bottom of the main filter screen 6. The water flow with a large impact force can clean the clogged main filter screen 6, and the cleaning effect is better.

[0032] like Figure 3As shown, the gear rotating device 5 includes a motor 501, which is fixedly connected to the middle of one side of the filtering mechanism 1, and the output shaft of the motor 501 is fixedly connected to a rotating rod 502, and the other end of the rotating rod 502 is fixedly connected to the middle of one side of the main filter screen 6, and the middle of the other side of the main filter screen 6 is fixedly connected to a driving gear 503, and the driving gear 503 is meshed with a secondary gear 504 in the opposite direction of the gear, and one side of the secondary gear 504 is rotatably connected to a support rod 505, and the other end of the support rod 505 is fixedly connected to a support plate 506, and the support plate 506 One end is fixedly connected to the inner side wall of the filter mechanism 1, the secondary gear 504 is located on one side of the support rod 505 and is fixedly connected to a rotating plate 507, the inner side wall of the filter structure is located at a position where the rotating plate 507 rotates to a position close to the side wall of the filter structure and is fixedly connected to a push switch 508, and one side of the auxiliary filter screen 7 is fixedly connected to a vibrator 509, and the vibrator 509 is fixedly connected to the inner side wall of the filter device; the user can start the motor 501 and the water pump 302 after working for a period of time, and the output shaft of the motor 501 can drive the rotating rod 502 to rotate, and the rotating rod 50 2 can drive the main filter 6 to rotate inside the filter mechanism 1. As we know, under the action of gravity, the main filter 6 below will accumulate more impurities. At this time, the motor 501 will rotate the main filter 6 by a quarter of a circle each time, and rotate the most seriously blocked part of the main filter 6 to the place directly opposite the nozzle of the nozzle 303. During this period, the water pump 302 pumps the water in the water tank 2 to the nozzle 303 to keep it working. The force of the water backwash will eject the impurities from the main filter 6, so that the main filter 6 can continue to work, which greatly improves the working efficiency. The efficiency is improved by reducing the time of manual processing. When the main filter 6 drives the rear driving gear 503 to rotate ten times, it will drive the secondary gear 504 to rotate one circle. The rotating plate 507 on the secondary gear 504 will press the push switch 508 to make the vibrator 509 work for a period of time, and the impurities on the auxiliary filter 7 will be vibrated and fall off, so that the auxiliary filter 7 can continue to work, thereby improving the work efficiency. Because there are fewer impurities on the auxiliary filter 7 and more impurities clog the main filter 6, the main filter 6 will drive the auxiliary filter 7 to be cleaned once after being cleaned many times.

[0033] like Figure 1 As shown in 4, the circulation reflux device 4 includes a reflux pipe 401, one end of the reflux pipe 401 is plugged into the bottom of one side of the water storage tank 2, and the other end of the reflux pipe 401 is plugged into the surface of the filter mechanism 1 and is located on the side of the water inlet pipe 101. A pressure pump 402 is fixedly connected to an inner section of the reflux pipe 401, and a filter element 403 is fixedly connected to the reflux pipe 401 on one side of the pressure pump 402; the treated sewage that still does not meet the water quality standards can be flowed to the filter element 403 for treatment through the pressure pump 402, and then enter the filter mechanism 1 through the reflux pipe 401 for further filtration.

[0034] like Figure 1As shown, the filtering mechanism 1 is fixedly connected to a sedimentation tank at the bottom in front of the main filter 6 and the auxiliary filter 7, and a cleaning port is provided at the bottom of the sedimentation tank; the impurities washed out and the impurities originally falling by gravity will fall into the sedimentation tank in front of the main filter 6 and the auxiliary filter 7, and when the water is discharged after being treated, the impurities can be cleaned at the cleaning port below.

[0035] like Figure 1 As shown, the water tank 2 is provided with an observation port 201 on one side of the pressurized flushing device 3, and a transparent plate 202 is fixedly connected to the inside of the observation port 201; after the sewage enters the water tank 2, the water level can be seen through the observation port 201 to control the entry and suspension of the sewage.

[0036] like Figure 3 As shown, the driving gear 503 rotates ten times to drive the secondary gear 504 to rotate one time; the main filter 6 is clogged with a lot of impurities, and after the main filter 6 is cleaned many times, it will drive the auxiliary filter 7 to be cleaned once.

[0037] like Figure 3 As shown, the rotating plate 507 is a trapezoid, and the side of the trapezoidal triangle is facing the push switch 508. The push switch 508 controls the vibrator 509 to turn on and off; the push switch 508 is pressed for convenience.

[0038] Working principle: When the user uses the device, sewage will enter the filtering mechanism 1 through the water inlet pipe 101. The sewage will first pass through the main filter 6 to filter out large particles of impurities, and then pass through the auxiliary filter 7 to filter out small particles of impurities, and then enter the water storage tank 2 through the outlet pipe 102. Before the sewage enters the water storage tank 2, the sewage will pass through the water quality detector 103 in the outlet pipe 102. The water quality can be seen from the display screen on the water quality detector 103. After the sewage enters the water storage tank 2, the water level can be seen through the observation port 201 to control the entry and pause of the sewage, and then pass The overpressure pump 402 will flow the treated sewage that still does not meet the water quality standards to the filter element 403 for treatment, and then enter the filter mechanism 1 through the return pipe 401 for refiltration, and repeat the cycle until the water quality is qualified. After the device has worked for a period of time, the filter screen will be clogged with impurities. The user can start the motor 501 and the water pump 302 after working for a period of time. The output shaft of the motor 501 can drive the rotating rod 502 to rotate, and the rotating rod 502 can drive the main filter screen 6 to rotate inside the filter mechanism 1. We know that under the action of gravity, the impurities at the bottom of the main filter screen 6 will accumulate more Impurities, at this time, the motor 501 will rotate the main filter 6 a quarter of a circle each time, and rotate the most seriously blocked part of the main filter 6 to the place opposite to the nozzle of the nozzle 303. During this period, the water pump 302 pumps the water in the water tank 2 to the nozzle 303 to make it work continuously. The force of the water backwash will eject the impurities from the main filter 6, so that the main filter 6 can work continuously, which greatly improves the work efficiency and reduces the time of manual processing. When the main filter 6 drives the rear driving gear 503 to rotate ten circles, it will drive the secondary gear 504 to rotate one circle, and the secondary gear 50 The rotating plate 507 on 4 will press the push switch 508 to make the vibrator 509 work for a period of time, and the impurities on the auxiliary filter 7 will be vibrated to fall off, so that the auxiliary filter 7 can continue to work, thereby improving the working efficiency. Because there are fewer impurities on the auxiliary filter 7, and the main filter 6 is blocked by more impurities, the main filter 6 will drive the auxiliary filter 7 to be cleaned once after being cleaned many times. The cleaned impurities and the impurities that originally fell by gravity will fall into the sedimentation tank in front of the main filter 6 and the auxiliary filter 7. When the water quality is treated and discharged, the impurities can be cleaned at the cleaning port below.

[0040] Step 1: Sewage enters the filter mechanism 1 through the water inlet pipe 101, filters impurities through the main filter screen 6 and the auxiliary filter screen 7, and then enters the water storage tank 2 through the water outlet pipe 102;

[0041] Step 2: The treated sewage (sewage that does not meet the standards) is flowed to the filter element 403 through the pressure pump 402 for treatment and then enters the filter mechanism 1 through the return pipe 401 for further filtration;

[0042] Step 3: start the starter motor 501 and the water pump 302 at a fixed time, the output shaft of the motor 501 drives the rotating rod 502 to rotate, and the rotating rod 502 drives the main filter 6 to rotate inside the filter mechanism 1, and the main filter 6 rotates a quarter of a circle each time;

[0043] Step 4: During this period, the water pump 302 pumps the water in the water tank 2 to the nozzle 303 to keep it working, and the force of the water backflow sprays the impurities out of the main filter 6;

[0044] Step 5: When the main filter 6 drives the rear driving gear 503 to rotate ten times, it will drive the secondary gear 504 to rotate one time, and the rotating plate 507 on the secondary gear 504 will press the push switch 508 to make the vibrator 509 work for a period of time, thereby vibrating the impurities on the auxiliary filter 7;

[0045] Step 5: The cleaned impurities and the impurities that originally fell by gravity will fall into the sedimentation tank in front of the main filter 6 and the auxiliary filter 7. When the water quality is treated, the impurities in the sedimentation tank are manually cleared out from the cleaning port below.
