Description

Technical Field

[0001] This utility model relates to the field of filter flushing technology, specifically a flushing device for a single centrifugal double-net filter. Background Technology

[0002] A dual-stage filter, also known as a dual-stage switching filter, consists of two stainless steel filters connected in parallel. It is a physical water treatment device used to remove suspended particulate matter from water, such as sand, soil, and plant debris. It uses filter media of different particle sizes and has many advantages, including novel and reasonable structure, good sealing, strong flow capacity, and simple operation. It is a versatile filtration device with a wide range of applications and strong adaptability, and can effectively purify water quality.

[0003] Existing single-centrifugal dual-net filter rinsing devices are mostly optimized to ensure more effective uniformity of filter screen rinsing. For example, Chinese utility model patent application number CN201110033869.2 discloses a "Mobile Rinsing Device for a Rotary Disc Filter," which includes two mobile rinsing supports, a main rinsing water supply pipe, multiple rinsing water supply branch pipes, multiple eccentric wheels (the same number as the rinsing water supply branch pipes), multiple rinsing nozzles, a rinsing support transmission rod, a rinsing pump, a first transmission belt, and a second transmission belt. In this invention, the main rinsing water supply pipe is fixed, while the eccentric wheels are used to move the rinsing water supply branch pipes. This makes it more flexible and safer to use, and more effectively ensures the uniformity of filter screen rinsing, allowing the filter screen to maintain its original balanced performance for a longer period, thus making it more durable.

[0004] Although the aforementioned single-centrifugal double-net filter flushing device has certain advantages in ensuring the uniformity of filter screen flushing more effectively, it still has certain drawbacks: when it is necessary to clean the inside of the single-centrifugal double-net filter, it is usually necessary for personnel to use the flushing device by hand, which increases the workload of personnel and easily leads to water waste.

The inlet 1 is externally connected to a three-way pipe and equipped with a reversing valve body, so that the outlet of the flushing wastewater is different from the inlet of the wastewater.

[0028] Please see Figure 3-4A flushing device for a single centrifugal double-net filter, comprising a water collection backwash assembly 91, a backwash pipe 92, a water pump 93, a backflow pipe 94, a reversing valve 95, a filter outlet pipe 96, and an overflow port 97. One end of the backwash pipe 92 is connected to the side of the water collection backwash assembly 91. The backwash pipe 92 is connected to the backflow pipe 94 via the water pump 93. The lower end of the backflow pipe 94 is connected to the reversing valve 95. The filter outlet pipe 96 is located below the backflow pipe 94 via the reversing valve 95. One end of the filter outlet pipe 96 is embedded in the water collection backwash assembly 91. The water collection backwash assembly 91 includes a water tank a1, a drive gear a2, a movable body a3, a vertical frame a4, a rotating rod a5, a shaft seat a6, and a drive motor a7. The drive gear... a2 is connected to the rotating rod a5. One end of the rotating rod a5 is connected to the output end of the drive motor a7. The other end of the rotating rod a5 is connected to the bearing a6. The drive gear a2 is engaged with the upper part of the movable body a3. The top of the vertical frame a4 is connected to the movable body a3 and is movable. The movable body a3 is located in the lower part of the interior of the water tank a1. The water collection backwash assembly 91 is connected to the drain pipe 6 through the filter pipe 96. The water tank a1 is connected to one end of the backwash pipe 92. The water tank a1 is connected to one end of the filter pipe 96. The connection of the backwash pipe 92 is higher than the connection of the filter pipe 96. The drive motor a7 is installed on the outside of the water collection backwash assembly 91. The bearing a6 is fixedly connected to the inner wall of the water collection backwash assembly 91.

[0029] Please see Figure 5 A flushing device for a single centrifugal double-net filter includes a movable body a3 comprising a turntable a31, a rotating gear a32, and a stirring plate a33. The outer end of the turntable a31 is fixedly connected to the inner wall of the rotating gear a32. The upper end of the stirring plate a33 is pressed into the bottom of the rotating gear a32. The bottom of the turntable a31 is connected to the top of a vertical frame a4. A bearing seat is installed at the bottom of the turntable a31 and is embedded in the inner side of the top of the vertical frame a4, so that the rotating gear a32 can rotate around the top of the vertical frame a4 after being meshed. The rotating gear a32 is meshed with the drive gear a2 below, and the rotating gear a32 is meshed with the drive gear a2 as it rotates, thereby rotating.

[0030] In summary, an external bend is connected to the outside of the outlet 1, allowing the water to be filtered to enter the single centrifugal filter cartridge 2. Inside the single centrifugal filter cartridge 2, the sand and gravel impurities in the water are separated and fall into the sand and gravel discharge tank 3. The water then enters the first filter 7 and the second filter 8 through the connecting pipe 4 and the three-way pipe 5, where it undergoes further fine filtration. The filtered pure water flows through the drain pipe 6 to the filter outlet pipe 96 and into the water tank a1. The water level in the water tank a1 rises continuously, and when it exceeds the overflow port 97, it is discharged outwards through the overflow port 97, providing personnel with filtered pure water. Since the water tank a1 contains pure water, when it is necessary to flush the first filter 7 and the second filter 8, the inflow of external water from the outlet 1 is stopped, and the suction pump 93 is started to draw water from the water tank a1, which then flows through the backwash pipe 92 and the backflow pipe 94 into the reversing valve 95. The reversing valve 95 is subjected to water pressure from different directions and automatically reverses its direction, allowing water to enter the filter pipe 96 and flow back into the first filter 7 and the second filter 8. Under the flushing pressure of the water, the filter structure inside the first filter 7 and the second filter 8 is flushed. The flushed water is discharged outward through the outlet 1, realizing the backwashing operation. Through the movable body a3, when the drive motor a7 is started, the drive gear a2 is driven by the rotating rod a5. The rotation of the drive gear a2 meshes with the rotating gear a32 below, causing the rotating gear a32 to rotate around the turntable a31 as the fulcrum, driving the stirring plate a33 to move in a ring, so that the water inside the water tank a1 is in a constantly active state. This prevents the small particles still contained in the filtered water from forming sediment at the bottom of the water tank a1, which would easily cause bottom dirt to accumulate inside the water tank a1. It also allows some water to be discharged outward after backwashing and then filtered again in subsequent processes.
