Due to the decelerating effect of the first filter assembly 4, when the water pressure in the first buffer area is too high, the detection rod 62 is pushed to move upwards, the detection rod 62 drives the shifting plate 75 to move upwards through the range increasing assembly 76, after the shifting plate 75 moves upwards, the movable plate 71 can be driven to move upwards, the moving plate 71 which moves upwards drives the second filter assembly 5 to move downwards through the transmission gear 74 and the toothed plate, the second filter assembly 5 moves downwards into the flow channel, and the second filter assembly 5 can perform filtering work;
The movable plate 71 moves upwards and then presses the clamping plate 78 to the right through the top slope, then the movable plate 71 moves upwards to the upper part of the top end of the clamping plate 78, the clamping plate 78 clamps the movable plate 71 after the upward movement after the return movement, in the process, the clamping plate 78 moves rightwards and is separated from the first filter assembly 4, and the second spring 77 pulls the first filter assembly 4 to move upwards; after the first filtering component 4 moves upwards, the water body quickly flows into the second buffer area, and the water pressure is reduced; in the process, the second filter assembly 5 moves downwards to perform filtering operation, and the first filter assembly 4 moves upwards to perform water pressure reduction;
After the water pressure is reduced, the detection rod 62 moves downwards to reset under the pushing of the first spring 63 and drives the shifting plate 75 to move downwards, and as the movable plate 71 is clamped above, the downward shifting plate 75 drives the first filter assembly 4 to move downwards independently, the first filter assembly 4 moves downwards to the inside of the flow channel and then contacts with the bottom slope of the clamping plate 78, the clamping plate 78 is extruded to move rightwards and then moves downwards to the lower part of the clamping plate 78, and the moved clamping plate 78 clamps the downward first filter assembly 4 again; the clamping plate 78 is separated from the movable plate 71 after moving rightwards, the movable plate 71 is pulled by the second spring 77 to move downwards, and the movable plate 71 which moves downwards drives the second filter assembly 5 to move upwards through the transmission gear 74 and the toothed plate, so that the whole device realizes automatic reset after reducing water pressure, can circularly work, the device not only improves the problem of rising water pressure in the filter box 2, but also automatically operates, has high automation degree, drives by taking the water pressure in the filtering process as power, omits an additional electric power system for monitoring the water pressure and controlling the lifting of the filter assembly, has simple structure and low use cost, and is convenient to use; meanwhile, after the filter assembly moves to the upper part of the filter box 2, the filter screen can be cleaned in a blowing brush mode or the like, so that the filter screen can be normally filtered, the cleaning work is not required to be stopped, the working efficiency is high, the filter assembly can be directly assembled in the existing sewage treatment production line for use, the suitability is good, and the transformation cost is further reduced.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
