s3: after all filter cartridge 31 equal filtering capability descends, through starting cleaning function, in the back washing process, through removing regulating plate 32 can control the degree of depth of filter medium 38, rotate through loose dish 24 simultaneously, loosen filter medium 38, accomplish after loosening and compress filter medium 38 through clamp plate 35 to this accomplishes the back washing, then can continue to carry out impurity water and filter.
The specific working process is as follows:
when the water filter works, when water needs to be filtered, the filtering media 38 in the filtering box 31 can fully filter water in the process that the water passes through the filtering box 31 on the surface of the filtering plate 3, for different water quality requirements, the first telescopic rod 33 can drive the adjusting plate 32 to move through the extension and contraction of the piston rod of the first telescopic rod 33, the adjusting plate 32 can adjust the size of the space in the filtering box 31, after the space in the filtering box 31 is reduced, the filtering media 38 in the filtering box 31 can be extruded, the overall thickness of the filtering media 38 is increased, otherwise, the overall thickness of the filtering media 38 is reduced, through the changing process of the filtering media 38, the adjustment of different filtering standards of the water can be realized, the condition that the impurity water uses the filtering media 38 in the same state under the condition of different water quality standards is avoided, and the filtering efficiency is lower when the low water quality requirement is met, the filtering resources are wasted, the filtering is easy to be out of the standard when the high water quality requirement is met, and meanwhile, by the structure, the thickness of the filtering medium 38 can be greatly reduced by moving the adjusting plate 32 in the reverse washing process, the reverse washing resistance is reduced, and the washing efficiency and the washing effect are improved; by arranging the rotating disc 2 and starting the first motor 21, the first motor 21 can drive the rotating disc 2 to rotate, the rotating disc 2 further drives the filter plate 3 to rotate, and the filter plates 3 rotate, so that filter boxes at different positions can rotate to positions below the guide holes of the guide plate 22, the work switching of the filter boxes at different positions is realized, the service cycle of the filter is prolonged, frequent reverse washing is avoided, and by arranging the dividing barrier strips 23, the dividing barrier strips 23 slide in the dividing barrier grooves, and the effective separation of different filter boxes is realized; by arranging the loosening disc 24, the second motor 25 can drive the loosening disc 24 to rotate through the rotation of the second motor 25, the rotation of the loosening disc 24 can stir the filter medium 38 in the filter box 31, so that loosening of the filter medium 38 is realized, and in the reverse washing process, the filter medium 38 in a loosening state is beneficial to effectively washing out internal impurities and can reduce the reverse washing resistance; by arranging the control panel 26, the second telescopic rod 27 can drive the control panel 26 to move through the extension and retraction of the second telescopic rod 27, the control panel 26 can drive the switch hole on the surface of the control panel to be communicated with and dislocated with the through hole on the surface of the pressing plate 35 through the movement of the control panel 26, the automatic closing of the pressing plate 35 is realized, when the loosening disc 24 rotates to loosen the filter medium 38 in the reverse washing process, the filter medium 38 in a stirring state is prevented from flowing out through the pressing plate 35, and after the loosening is completed, the pressing plate 35 is opened, and the normal reverse washing work can be performed at the moment; by arranging the third telescopic rod 28, in the moving and adjusting process of the adjusting plate 32, due to the elastic force of the spring 37, the baffle plate 36 is always in contact connection with the adjusting plate 32 and is automatically adjusted, because the piston rod of the third telescopic rod 28 is positioned in the groove hole, the third telescopic rod 28 is not affected in the adjusting process of the baffle plate 36, after reverse washing is completed, the baffle plate 36 is all retracted into the adjusting groove by controlling the contraction of the third telescopic rod 28, the pressure plate 35 is completely opened, and the filtering resistance can be greatly reduced when filtering water; by providing the intermediate duct 14 on the surface of the filter housing 1, the two filter plates 3 can be respectively backwashed by adjusting the three control valves through the intermediate duct 14.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
