Detailed ways

In order to make it easy to understand the technical means, creative features, objectives and effects of the present utility model, the present utility model will be further elaborated below in conjunction with specific implementation modes.

As shown in Figures 1 and 2, a spiral centrifugal sewage filter mainly consists of a box-type housing 1, a water inlet filter drum device 2, a sewage discharge device 3, a backwash device 4 and a controller 5. The box-type housing 1 A drainage outlet 6 is provided at the bottom of the side wall for filtered water to be discharged; in practical applications, multiple drainage outlets 6 can also be installed according to the amount of water to help timely drainage.

As shown in Figure 3, the water inlet filter drum device 2 includes a cylindrical structure welded by two wheel frames 16 and a number of spiral guide bars 17. A rotating shaft 13 is connected across the inside of the structure. A water inlet pipe 14 is also installed on the outside of one end. The structure composed of the rotating shaft 13 and the water inlet pipe 14 is rotatably connected to the box-type housing 1 through bearings and bearing seats. The wall of the water inlet pipe 14 is also provided with an integrated structure. The arc-shaped water outlet 15 is located inside the water inlet filter drum device 2. A cylindrical polygonal frame 18 is also fixedly installed on the outside of the cylindrical structure, and the outside of the polygonal frame 18 is fixed. A cylindrical filter 19 is installed.

As shown in Figure 4, the sewage discharge device 3 mainly consists of a sewage tank 7, a water connection pipe 8, a sewage pipe 9, an electric ball valve 10 and a liquid level sensor 11. The sewage tank 7 is located at the head of the sewage discharge device 3, in the water inlet filtration turn. Just below the end of the drum device 2, the bottom of the sewage tank 7 is connected to the water pipe 8 through an elbow. The water pipe 8 passes through the box shell 1 and is connected to a sewage pipe 9 externally. A sewage pipe 9 is installed on the sewage pipe 9. The electric ball valve 10 and the liquid level sensor 11 are installed in the sewage tank 7 to detect the water level of the sewage tank 7, and the liquid level sensor 11 is installed on the inner wall of the box shell 1 through the mounting bracket 12. The liquid level sensor 11 is electrically connected to the controller 5, and sends the sensed water level signal to the controller 5, and then the controller 5 controls the switch of the electric ball valve 10.

As shown in Figure 5, the backwash device 4 includes a high-pressure flushing pump 20. The high-pressure flushing pump 20 is fixedly installed on the side wall of the box-type housing 1 through bolts. The water inlet of the high-pressure flushing pump 20 is connected to a water suction pipe 21. The end of the water pipe 21 is provided with a filter and extends into the inside of the box-type housing 1. The water outlet of the high-pressure flushing pump 20 is connected to a water supply pipe 22, and the end of the water supply pipe 22 is connected to a flushing pipe 23. The flushing pipe 23 is fixed. On the inner wall of the box-type housing 1, located obliquely above the water inlet filtering drum device 2, a number of flushing nozzles 24 are installed on the surface of the flushing pipe 23 to align with the water inlet filtering drum device 2. The high-pressure flushing pump 20 adopts timing start and stop. , controlled by controller 5.

In actual use, the water that needs to be filtered enters the filtering device through the water inlet pipe 14. Since the incoming water has a certain flow rate, it is then sprayed out from the arc-shaped water outlet 15, and the arc-shaped water outlet 15 is oriented in the opposite direction. With the spiral guide bar 17 inside the drum, the spiral structure of the spiral guide bar 17 is like a blade. When it is impacted by the continuous water flow, it will slowly rotate with the wheel frame 16, and the polygon mounted on it will rotate. The skeleton 18 and the cylindrical filter screen 19 will rotate accordingly. After the continuous impact of the water flow and the gravity of the entire water inlet filter drum device 2 form inertia, the water inlet filter drum device 2 will continue to rotate to generate centrifugal force, and The water flow entering the interior can be filtered and separated by the cylindrical filter 19. The filtered clean water directly enters the box housing 1, and the impurities filtered by the cylindrical filter 19 will be formed with the newly incoming water flow. The mixture is discharged from the other end along the rotation of the spiral guide bar 17, and just falls into the sewage tank 7; when the liquid in the sewage tank 7 accumulates to a certain height, it is sensed by the liquid level sensor 11, and the liquid level sensor 11 will send a signal to the controller 5, and the controller 5 will control the electric ball valve 10 to open, so that the dirt in the sewage tank 7 together with the accumulated water will be discharged and collected through the water connection pipe 8 and the sewage pipe 9.

In the actual filtration process, sometimes the filtered debris blocks the cylindrical filter 19, which will affect the filtration efficiency of the cylindrical filter 19 over time. At this time, only the filter drum device passes through the water inlet. 2. It is difficult to remove blocked impurities due to its own centrifugal force, so the controller 5 needs to control the high-pressure flushing pump 20 to be turned on regularly for a period of time, so that the high-pressure flushing pump 20 can extract the filtered water inside the box-type housing 1 through the water pumping pipe 21, and send it through The water pipe 22 is pumped to the flushing pipe 23, and then is sprayed with high pressure from the flushing nozzle 24, impacting the cylindrical filter 19 from the outside, thereby flushing out the impurities stuck in the mesh of the inner wall of the cylindrical filter 19, and then through the spiral guide strip 17 is directed to the sewage tank 7 and discharged according to the preset program. The entire process can be automated and only needs to provide simple power supply to the controller 5, the electric ball valve 10 and the high-pressure flushing pump 20. The core filtration process does not require additional driving force input, achieving high efficiency and low energy consumption.
