Abstract

The invention discloses a variable filter element sewage preliminary treatment equipment, which comprises a frame, a conical tank is installed on the frame, a power mechanism is installed on the frame, a sewage discharge mechanism is installed on the conical tank, The variable-pitch filter element and the swirl mechanism are installed on the sewage discharge mechanism respectively, and the variable-pitch filter element includes a main filter piece fixed on the inner wall of the conical tank. As for the electromagnetic string, the two ends of the plurality of electromagnetic strings are symmetrically slidably sleeved and installed with two secondary filters. The larger impurities in the sewage are settled and removed by means of centrifugal swirl, and the fine impurities are filtered out by the variable-pitch filter element, and the variable-pitch filter element is washed by the variable-pitch flushing method to make the washing impurities swirl and settle , realize the preliminary treatment of sewage, high treatment efficiency, reduce the consumption of consumables, reduce the waste of water, more environmentally friendly and lower cost.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a variable filter element sewage primary treatment equipment. Background technique [0002] The existing preliminary sewage treatment equipment usually adopts the method of sedimentation in the treatment tank or direct filtration in the filter box. The sedimentation time in the treatment tank is long, and the efficiency is low, and the scope of application is small. The direct filtration efficiency of the filter box is high and occupies an area. It is small and has a wider application range, but the filter material in the filter box is easily blocked due to filtering a large amount of sewage, so the internal filter material needs to be replaced frequently, which increases the consumption of consumables, that is, increases the cost of use, and has a backwash filter box Even if the consumption of consumables is reduced, backwashing the filter material causes a lot of water waste, wh...
