Self cleaning filter is set with many doctor blades in each filtering gap, under the supporting of reduction motor or hand wheel, the operation doct or blade clears away the foreign material in each filtering gap in time, to overcome the defects of low efficiency of disassembling and washing the filtering net. Due to cleanring way the dreg rapidly and immediately, the process is kept smooth and the efficiency is improved greatly, even more, the equipment can take effect on protecting the environment. This filter is the necessary filtering equipment for the polyurethane industry, edible oil, paint, glue adhesive and so on, especially it is the product that can't be substituted by other filtering equipment is supplied for filtering the high concentration raw material, its filtering accuracy is up to 0.1-0.8mm, it has strong ability of pressure-resistant and durability, Even it can realize the continuous filtering, in terms of these, at present, it has been widely used in automation industry.
Performance feature 1. Innovation Self cleaning and rapid slag off 2. Environment protection Free from disassembling and washing filter element 3. Resource conservation Disintegrate granular raw material 4. Reliable Strong ability of pressure-resistance, high stability 5. High efficiency Applicable for high concentration raw material
Working principle: Self-cleaning filter is also named the doctor blade self-cleaning filter, the medium goes into the barrel directly via material inlet, is filtered through the filter element gap from outside to inside, the medium filtered flows to the upper cleaning port from lower to upper, Because the foreign material more than filter disc gap is blocked, When the filter disc component runs for some time, the filter core gap may be jammed, the driving equipment drives the filter element component(each doctor blade just inserts into the gap of filter element component), the foreign material can be cleared away from the filter disc gap smoothly to keep the filter element gap no block. When the bottom barrel is stored enough foreign material, only open the eject valve, the foreign material can be drained well, in order that the processing pressure is kept normal.
Both filtering disc and doctor blade are made of stainless steel. Hereinto, the doctor blade is treated with high science and technology, so the performance of pressure-resistance and durability is the best among any filtering equipment. The granular material in the liquid is disintegrated by means of relative rotation of doctor blade.
