[0002] Publication No. CN107837579A provides a continuous sewage desilting and sand filtering device. This device can perform continuous filtering, but the filter screen cannot be cleaned in time during the filtering process, and the filter screen is prone to clogging, which will affect the filtering process
[0003] The publication number is CN107789893A, which provides an anti-blocking sewage filtration and sedimentation treatment device. This device drives the brush rod to move up and down through the telescopic rod, and then removes the impurities on the filter plate to prevent clogging. This method cannot prevent clogging on the filter screen. The deeper dirt in the hole is removed, and the dirt is easily pushed into the filter hole during cleaning, so the cleaning effect is poor

The invention provides a multi-stage filter device, which comprises a rack, a primary filter mechanism, a secondary filter mechanism and a water tank. The primary filter mechanism is installed on therack. The secondary filter mechanism comprises a water filter tank I, filter screens, discs, a support shaft, a biaxial cylinder I, a connecting plate and a connecting rod. The water filter tank I isfixedly installed at the bottom of the rack; the three filter screens are installed at equal intervals inside the water filter tank I; the support shaft is installed on the water filter tank I; the three discs respectively fixedly sleeve the support shaft, and the three discs are respectively located below the three filter screens; and the biaxial cylinder I is fixedly in transmission connection with the support shaft through the connecting plate and the connecting rod. With tapered rods on the three discs aligning water leakage holes I on the filter screens, sewage undergoes graded filtrationfrom top to bottom; and the tapered rods can push out dirt on the water leakage holes I to realize the anti-blocking function. Through the primary filter mechanism, sewage is treated; and through a discharge mechanism, large-grained dirt is discharged. Thereby, the filter effect is guaranteed.
Description
technical field [0001] The invention relates to the technical field of filtering equipment, in particular to a multi-stage filtering device. Background technique [0002] Publication No. CN107837579A provides a continuous sewage desilting and sand filtering device. This device can perform continuous filtering, but the filter screen cannot be cleaned in time during the filtering process, and the filter screen is prone to clogging, which will affect the The process of filtering. [0003] The publication number is CN107789893A, which provides an anti-blocking sewage filtration and sedimentation treatment device. This device drives the brush rod to move up and down through the telescopic rod, and then removes the impurities on the filter plate to prevent clogging. This method cannot prevent clogging on the filter screen. The deeper dirt in the hole is removed, and the dirt is easily pushed into the filter mesh hole during cleaning, and the cleaning effect is poor. Contents of...
