DETAILED DESCRIPTION

[0022] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] Please refer to Figure 1-6 , a high-efficiency multi-stage filtering device, comprising a first vertical plate 4, a second vertical plate 5 and a filter cartridge 7 between the first vertical plate 4 and the second vertical plate 5, the filter cartridge 7 can rotate between the first vertical plate 4 and the second vertical plate 5, and a flushing mechanism is provided directly above the filter cartridge 7, the flushing mechanism cleans the impurities attached to the filter cartridge 7 (inner wall), and the filtered water flows out from under the second vertical plate 5; a water inlet 41 is provided on the first vertical plate 4, and the water inlet 41 cooperates with the port of the filter cartridge 7; during use, the filter cartridge 7 is in a rotating state, after the sewage enters the filter cartridge 7 from the water inlet 41, the impurities remain on the inner wall of the filter cartridge 7, and the filtered water passes through the filter cartridge and flows out from under the second vertical plate 5, and the impurities remaining on the inner wall of the filter cartridge 7 are flushed by the flushing mechanism to avoid clogging the filter holes, thereby achieving the sewage circulation filtration demand.

[0024] The side wall of the filter cartridge 7 is evenly provided with filter holes, a gap is left between the filter cartridge 7 and the second vertical plate 5 , and the width of the gap is smaller than the diameter of the filter hole to prevent impurities from flowing out from between the filter cartridge 7 and the second vertical plate 5 .

[0025] In the solution of the utility model, four meshing gears 72 are respectively provided on the opposite sides of the first vertical plate 4 and the second vertical plate 5, and the outer circumferences of the two ends of the filter cartridge 7 are provided with meshing teeth 71. The filter cartridge 7 cooperates with the meshing gears 72 at both ends through the meshing teeth 71. A motor 51 is provided on the outer side of the second vertical plate 5. The motor 51 is transmission-connected with one of the meshing gears 72. After the motor 51 is running, the filter cartridge 7 rotates between the first vertical plate 4 and the second vertical plate 5 through the meshing teeth 71 and the meshing gears 72.

[0026] That is to say, one of the meshing gears 72 is connected to the motor, and this gear is the master-slave gear. When the driving gear rotates, the filter cartridge starts to rotate, thereby achieving the purpose of cyclic filtering.

[0027] Specifically, the flushing mechanism includes a flushing pipe 61, a water inlet pipe 62 and a flushing nozzle 63. A cross bar 6 is provided between the first vertical plate 4 and the second vertical plate 5. The flushing pipe 61 is fixed below the cross bar 6 along the length direction. The flushing nozzles 63 are arranged in sequence below the flushing pipe 61. One end of the water inlet pipe 62 is connected to the flushing pipe 61, and the other end extends upward through the cross bar 6. The water inlet pipe 62 is connected to a water source and a pump. The flushing nozzle 63 removes impurities on the inner wall of the filter cartridge 7 after spraying water.

[0028] When filtering, impurities will adhere to the inner wall of the filter cartridge 7. When the filter cartridge 7 rotates, the impurities will rotate with it. When the impurities pass through the flushing pipe 61, flushing water will be sprayed on the outer wall of the filter cartridge. The flushing water will blow the impurities down through the filter holes, thereby avoiding clogging the filter holes.

[0029] In order to discharge impurities in time and ensure the continuous use of the filter cartridge, a receiving box 8 for receiving filtered impurities is further provided in the filter cartridge 7. One end of the receiving box 8 is fixed to the second vertical plate 5, and the other end is fixed to the first vertical plate 4 through a connecting plate 81. An outwardly extending sewage pipe 82 is provided at the end of the receiving box 8, and the sewage pipe is connected to an external pump, wherein the receiving box is arranged directly below the flushing nozzle 63.

[0030] When impurities pass through the flushing nozzle 63 as the filter cartridge rotates, the flushing nozzle 63 will blow the impurities down to prevent them from sticking to the filter cartridge, and the blown impurities will fall into the receiving box 8 below. As the external pump runs, the flushing water and impurities in the receiving box 8 will be pumped away at the same time, thereby achieving the timely discharge of impurities and ensuring the use requirements of the filter cartridge for cyclic rotation filtration.

[0031] Based on the above embodiment, the first vertical plate 4 and the second vertical plate 5 are vertically arranged in the channel 1, the two sides and the bottom of the first vertical plate 4 are sealed and connected to the inner wall of the channel 1, and the two sides of the second vertical plate 5 are sealed and connected to the two sides of the inner wall of the channel 1. Please refer to Figure 6As shown in the figure, the top of the second vertical plate is flush with the first vertical plate, while the bottom is shorter than the first vertical plate. After the sewage passes through the filter cartridge in the channel 1, it flows out from the bottom of the second vertical plate 5 to meet the flow of filtered water.

[0032] In addition, an opening 2 is provided at the end of the channel 1, and a mixture of sand and pebbles is provided in the channel of the opening 2 to simulate a natural filtration scene. The water filtered by the filter cartridge passes through the mixture of sand and pebbles again to achieve multi-stage filtration. An outlet pipe 3 is provided at the end of the open channel, and the filtered water is finally discharged from the outlet pipe 3 to improve the degree of purification.

[0033] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
