In order to ensure that the pressure-collecting spring 18 can quickly recoil water flow above the driving cylinder 14 out of the guide pipe 7 during the recoil process, the compression elastic coefficient of the pressure-collecting spring 18 is far larger than the gravity value of the water flow above the pressure-collecting block 17 and the friction force of the movable cylinder 13, the driving cylinder 14 and the pressure-collecting block 17, and meanwhile, the maximum magnetic attraction force between the movable magnetic block 19 and the fixed magnetic block 20 is larger than the compression value of the pressure-collecting spring 18, so that the normal operation of the recoil effect can be ensured.
The using method of the invention has the following working principle: firstly, fixedly mounting a rack 1 of the machine to a proper position, secondly, electrifying a vibration motor 2 of the machine, further vibrating by the vibration motor 2, and putting mud into the machine from the top of the rack 1;
and (3) filtering the working state: the slurry poured into the frame 1 is firstly guided by the guide frame 6, and the slurry is made to rush to the driving frame 5, the driving frame 5 drives the rotary screen 4 to rotate, at the same time, the slurry is filtered from the rotary screen 4, and at the same time, the filtered slurry flows into the inner cavity of the fixed cylinder 11 from the draft tube 7, and then, the filtered mud directly falls to the upper part of the pressure collecting block 17 through the movable cylinder 13, and after the mud after continuous filtration is filled, the pressure-collecting block 17 is pressed so that the pressure-collecting block 17 is attached to the hexagon at the bottom of the movable cylinder 13, and the gushed mud is continuously poured above the pressure-collecting block 17, and when the gushed mud reaches the position of the folding filter screen 12, will be filtered by the folding filter screen 12, and then the secondary fine filtering of the slurry is completed, at the same time, the slurry placed in the fixed cylinder 11, smaller impurities on the inner wall of the water collector can automatically sink above the pressure collecting block 17 under the influence of the gravity of the water collector;
clearing the blockage in a working state: because the slurry continuously pushes the rotary screen 4, not only the filtering is carried out through the rotary screen 4, but also the continuous rotating force is provided for the rotary screen 4 through the driving frame 5, thereby the impurities blocked on the rotary screen 4 are thrown out by the rotating force of the rotary screen 4, and because the rotary screen 4 continuously rotates, further the rotary screen 4 drives the driving gear 8 to synchronously rotate, so that the pressure collecting gear 9 and the rotary screen 4 rotate together, then, in the rotating process of the pressure collecting gear 9, the pressure collecting gear 9 drives the driving blade 15 to synchronously rotate, further the top of the driving blade 15 continuously scrapes on the inner wall of the folding filter screen 12, the cleaning of the inner wall of the folding filter screen 12 is realized, meanwhile, because the tooth number between the driving gear 8 and the pressure collecting gear 9 is different, in the rotating process of the pressure collecting gear 9 driven by the driving gear 8, the pressure collecting gear 9 rotates relatively slowly, so that the slowly rotating pressure collecting gear 9 drives the telescopic rod 16 to rotate synchronously, meanwhile, in the rotating process of the telescopic rod 16, the relative position between the movable magnetic block 19 and the fixed magnetic block 20 is changed, and because the movable magnetic block 19 is of gradient type magnetism, the attraction between the movable magnetic block 19 and the fixed magnetic block 20 can be continuously increased in the rotating process of the movable magnetic block 19, and further the pressure collecting spring 18 is compressed, finally, when the magnetic attraction between the movable magnetic block 19 and the fixed magnetic block 20 is weakest after the movable magnetic block 19 rotates for one circle, the pressure collecting spring 18 cannot be compressed, and under the elastic force of the pressure collecting spring 18, the pressure collecting block 17 rapidly pushes the pressure collecting block 17 to move upwards, and simultaneously the pressure collecting block 17 can be separated from the bottom of the telescopic rod 16, and in the process of continuous rising, as the bottom of the movable barrel 13 can pass through an area smaller than the end area of the pressure collecting block 17, therefore, the movable cylinder 13 is pushed to move upwards, the folding filter screen 12 is contracted and folded through the movable cylinder 13, the slurry cannot pass through the folding filter screen 12, then, the slurry pushed through the pressure collecting block 17 acts on the driving blade 15, and the rotation of the driving blade 15 is accelerated, so that the driving blade 15 drives the pressure collecting gear 9 to drive the driving gear 8 to drive the rotary screen 4 to rotate rapidly, the force of throwing out the blockage is increased, meanwhile, the slurry above the pressure collecting block 17 recoils from the draft tube 7 and is rapidly ejected from the rotary screen 4, and the blockage is recoiled and cleaned, finally, after the pressure collecting spring 18 extends out completely, the filtered slurry in the rotary screen 4 is poured into the fixed cylinder 11 again, and the folding filter screen 12 is unfolded again under the action of gravity and the impact of the slurry on the movable cylinder 13, the periodic blockage removal is realized according to the steps;
and (3) collecting the state: the mud with less impurities filtered by the rotary screen 4 and the folding filter screen 12 enters the first-stage storage cavity 101, the mud with more impurities continuously flows to the vibrating screen 3 from the rotary screen 4, coarse filtering of the mud remained after filtering by the rotary screen 4 is realized by the vibrating screen 3, the mud finally flows to the second-stage storage cavity 100, and the impurities after filtering slide out of the rack 1 from the vibrating screen 3.
