The working process of the large-flow horizontal filter with the automatic backwashing function provided by the embodiment of the utility model is as follows: when the filter works normally, liquid to be filtered enters the inner cavity of the shell 1 through the liquid inlet 2 and enters the filter element 6 through the inlet of the filter element 6, and water filtered by the filter element 6 is finally discharged through the liquid outlet 3, so that the sewage is filtered;

in the filtering process, a part of impurities are deposited in the filter element 6, and after more and more impurities are generated along with the filtering work, the circulation effect of the filter element 6 is influenced, so that after the filter element 6 is used for a period of time and the filter element 6 needs to be backflushed, an operator can control the electromagnetic valve at the top end of the venturi decompression blow-off pipe 11 to be opened through the control system, the venturi decompression blow-off pipe 11 is communicated with the two filter elements 6 through the backflushing pipe 8, the outlet end of the venturi decompression blow-off pipe 11 is communicated with the outside, and certain water pressure exists in the filter cavity, so that water can automatically reversely enter the two filter elements 6 communicated with the backflushing pipe 8 and is finally discharged through the venturi decompression blow-off pipe 11, and solid impurities in the filter element 6 can be reversely flushed in the flowing process, so that the automatic backflushing purpose of the filter element 6 is realized;

after the current filter element 6 is backwashed for a period of time, an operator controls the motor 7 to work through the control system, the motor 7 drives the backflushing pipe 8 to rotate for a certain angle, and the backflushing pipe 8 stops rotating until two inlets 9 of the backflushing pipe 8 are respectively connected with inlets of the other two filter elements 6 (because the number of the filter elements in each filter element ring group is known, the purpose can be realized only by controlling the rotating angle of the backflushing pipe 8);

the operations are repeated until all the filter elements 6 are subjected to one-time back washing, and the back washing operation of the filter element assembly is completed.

Each filter element 6 in the device is fixed between the first plate 4 and the second plate 5 through a set of special fixing mechanism, and the corresponding filter element 6 can be drawn out of the device only by opening the fixing mechanism, so that the filter elements 6 are very convenient to replace and maintain; when the filter element 6 needs to be replaced, the hand wheel 13 is only required to be rotated, the limiting block 12 is screwed out of the first plate 4, the limiting block 12 and the spring 14 are pulled out of the threaded hole formed in the first plate 4, and then the corresponding filter element 6 is pulled out of the first plate 4; during installation, the hand wheel 13 is rotated to screw the limiting blocks 12 into the threaded holes on the first plate 4, and the springs 14 can tightly press the corresponding filter element 6.
