Description

Technical Field

[0001] This invention relates to the field of water filtration technology, and in particular to a floating self-rotating backwashing water filter. Background Technology

[0002] Most environmental water bodies contain a large amount of silt and other floating matter. In existing technologies, hydrocyclones or water filters are usually used for filtration. While hydrocyclones can be used to remove impurities, their effect on separating small particles is limited, and the treated water quality cannot meet usage requirements. If only water filters are used, a large amount of silt and other floating matter will quickly clog the filters, leading to reduced processing efficiency or failure of the unit. Summary of the Invention

[0003] The purpose of this invention is to provide a floating self-rotating backwashing water filter, which sprays water from the inside out onto the filter screen and a water-holding hopper fixed on the side plate through the branch pipe water passage, backwashing pipe and nozzle, to realize the backwashing function of the filter screen and the gravity of the water-holding hopper to make the rotating drum assembly automatically and continuously rotate, thereby improving the filtration efficiency.

The water filter side plate is movably connected to the floating unit. The water filter side plate is provided with several water-holding hoppers. A rotating cage filter screen is provided between two water filter side plates. The rotating cage filter screen is used to filter the incoming water. A water supply unit is provided inside the rotating cage filter screen. The water supply unit is used to extract the filtered incoming water inside the rotating cage filter screen.

[0007] The water supply unit includes a water pump, a water pump outlet main pipe, and a backwash water pipe. One end of the water pump outlet main pipe is connected to the water pump, and the other end of the water pump outlet main pipe passes through the side plate of the water filter and is connected to a water supply pipe. One end of the backwash water pipe is connected to the water pump, and the other end of the backwash water pipe is used to rinse the rotating drum filter screen and supply water to the water hopper. The gravity of several water hoppers drives the rotating drum assembly to rotate.

[0008] In one embodiment of the present invention, the support unit further includes a rotating cage fixing bracket, the two ends of which are fixed above the floating unit, the rotating cage assembly is disposed on the rotating cage fixing bracket, and the rotating cage assembly is movably connected to the rotating cage fixing bracket.

[0009] In one embodiment of the present invention, the floating unit includes two symmetrically arranged floats, and the bottom left and right sides of the rotating cage fixing bracket are respectively fixed above the left and right floats.

[0010] In one embodiment of the present invention, the rotating drum assembly further includes a rotating drum filter support, and the two side plates of the water filter are connected by a plurality of rotating drum filter supports, wherein the rotating drum filter is fixed on the rotating drum filter support.

[0011] In one embodiment of the present invention, the rotating drum assembly further includes a central tube shaft, the left and right ends of which are fixed above the rotating drum fixing bracket. The central tube shaft passes laterally through the left and right side plates of the water filter, and the side plates of the water filter are rotatably connected to the central tube shaft.

[0013] In one embodiment of the present invention, the water supply unit further includes a water pump outlet main pipe, one end of which is connected to a water pump, and the other end of which is connected to a water pump outlet main pipe. The water pump outlet main pipe is located inside a pipe on one side of the central pipe shaft, and the water pump outlet main pipe passes through the central pipe shaft and is connected to an external water supply pipe.

[0014] In one embodiment of the present invention, the water pump is connected to an external power source via a water pump power line, which is located inside the pipe on the other side of the central tube shaft.

[0015] In one embodiment of the present invention, the water supply unit further includes a water pump outlet branch pipe, and a branch line is led out from the main water pump outlet pipe and connected to one end of the water pump outlet branch pipe, and the other end of the water pump outlet branch pipe is connected to a backwash water pipe.

[0021] 3. The present invention achieves the purpose of filtering all water pumped by the pump inside the rotating drum by covering the cylindrical rotating drum assembly with a rotating drum filter screen. This creates a closed space in which external water can only pass through the filter screen.

[0022] 4. The present invention sets up a water pump in the rotating cage assembly to draw water from the cage and then divides the water into two outlets through the main water pump outlet pipe. One outlet is a water pump outlet branch pipe with a smaller water volume, and the other outlet is a water pump outlet main pipe with a larger water volume. The water from the water pump outlet branch pipe is sprayed from the inside to the outside of the rotating cage filter screen and the water hopper fixed on the side plate through the backwash water pipe, so as to realize the backwash function of the rotating cage filter screen and the gravity of the water hopper to make the rotating cage body rotate automatically and continuously.

[0023] 5. In this invention, the main outlet pipe of the water pump is set inside one side of the central tube shaft of the rotating cage to deliver the filtered water to the outside of the rotating cage assembly. The power cord of the water pump connected to the water pump is set inside the other side of the central tube shaft of the rotating cage. This achieves the purpose of allowing the rotating cage assembly to rotate autonomously and backwash automatically while delivering the filtered water pumped by the water pump and connecting the power cord of the water pump.
