The working principle is as follows: the feeding guide pipe 1 is butted with a petroleum pipeline, petroleum enters the inner filtering mechanism 2 from the feeding guide pipe 1 for filtering, and is finally discharged from a discharge outlet 3, in the high-pressure oil transportation process, the bending angle of the folding filter plate 22 changes along with the pressure of the petroleum transmission, when the transmission pressure is larger, the angle of the back of the folding filter plate 22 is gradually increased, and the friction resistance exists between the outer extension pull plate 24 and the movable slot 23, so that the filtering and adsorbing hole piece 25 is properly extruded to deform, at the moment, the size of the filtering and adsorbing hole piece 25 is reduced by extrusion dredging, thereby increasing the petroleum transmission resistance, reducing the petroleum flow rate, ensuring the sufficient filtering of the petroleum, simultaneously improving the filtering precision, and filtering fine particle substances together; when a large amount of sand and stones are accumulated on the surface of the folding filter plate 22, the filtering and adsorbing hole piece 25 is gradually blocked, the folding filter plate 22 is gradually extruded and turned to a horizontal state, the outward extending pull plate 24 completely moves to the edge position of the filtering through groove 21 at the moment, the discharging valve plate 29 is gradually opened by extrusion force under the pressure of petroleum transmission pressure, petroleum is discharged outwards, the petroleum at the blocking position is released, the sand and stones accompanied with filtering in the petroleum are directionally cleaned, the sustainable filtering work is realized, after the sand and stones are completely discharged, the folding filter plate 22 restores the original position by the self elasticity of the folding filter plate 22, and meanwhile, the discharging valve plate 29 is automatically closed after the pressure is reduced, so that the stable proceeding of the subsequent filtering work is ensured; when the adsorption containing hole 251 is gradually blocked by sand, the pressure of liquid collected on the surface of the limiting conical plate 252 is gradually increased, the limiting conical plate 252 slides towards the back surface in the adsorption containing hole 251, the limiting conical plate 252 gradually extrudes the pressure discharge liquid bag 257 at the moment, oil absorbed in the pressure discharge liquid bag 257 is sprayed out from the discharge duckbill valve 254 and the lateral pressure relief holes 255, and the sand and stones around the inside and the outside of the filter hole are sprayed outwards, so that the cleaning of the blocked sand and stone is convenient, the sand and stone are prevented from being always blocked in the structure, and the purpose of improving the filtering efficiency is achieved; when the folding filter plate 22 is gradually turned over towards the horizontal direction, the folding filter plate 22 drives the conduction pull rod 27 to be in threaded transmission with the positioning shaft sleeve 26, so that the sweeping rod member 28 is driven to rotate, the axial fluidity of petroleum is increased, the filtering efficiency is improved, meanwhile, the adjusting fan piece 281 gradually approaches the position of the material guide brush head 285 towards the outer side of the folding filter plate 22 under the action of centrifugal force, the filtering and adsorbing hole member 25 at the outer side is cleaned, the cleaning effect of sand and stones is ensured, and a large amount of petroleum waste caused by long-time blockage is avoided; the magnetic attraction pieces 284 and the limiting conical plate 252 have magnetic attraction, so that the limiting conical plate 252 can restore the initial position, the sand and the stone in the limiting conical plate can be conveniently discharged outwards, the guiding scraper 282 conducts the mixture of the sand and the stone to the position of the discharge valve plate 29, the sand and stone discharge efficiency is accelerated, and the tedious cleaning operation of workers is reduced.
