The specific embodiment
But the online cleaning filter of rag bar impurity in a kind of filtering crude oil, comprise filter element cavity 13, the main flow pipeline 8 that is connected with described filter element cavity 13, and the dirt storage room 10 and the blowoff valve 11 that place described filter element cavity 13 belows, it is characterized in that: cylindrical wall one side of described filter element cavity 13 is connected with the import of main flow pipeline 8 by through hole and communicates, and opposite side is connected with the outlet of main flow pipeline 8 by filter screen 9 and communicates; The upper end of described filter element cavity 13 is fastenedly connected with upper flange 14 and quick-actuating closure plate 15, and guide thimble 18 places the center of described quick-actuating closure plate 15, and spacing briquetting 17 is fixedly connected with the upper end of described guide thimble 18; Also be equipped with cleaning piston plate 12 in the described filter element cavity 13, the surface of described cleaning piston plate 12 is equipped with a plurality of filter openings, the center of described cleaning piston plate 12 is fixedly connected with the lower end of connecting rod 1 in placing guide thimble 18, and can move up and down with the lifting of described connecting rod 1; The top of the screen pack 9 of described filter element cavity 13 communicates with the outlet connecting pipe road of main flow pipeline 8 by shunt valve 6.
The upper end of described connecting rod 1 is connected with an end of handle 3, and the middle-end of described handle 3 is flexibly connected take the upper end of support post 2 as fulcrum, and the other end is the operating side of handle 3.Moving up and down of operating side by operating grip 3, realize the reciprocating motion of connecting rod 1, and then drive cleaning piston plate 12 and do slowly and pump, the extreme position that cleaning piston plate 12 pumps is respectively the up and down both sides of the screen pack 9 that communicates with 8 outlets of main flow pipeline: handle 3 operating sides press down, be connected and fixed by limiting lock tight rope 4 and limiting lock tight rope hook 5, realize the upper limit of cleaning piston plate 12 spacing; Unclamp limiting lock tight rope 4, handle is carried on 3 operating sides, realizes that by spacing briquetting 17 lower limit of cleaning piston plate 12 is spacing.
During use, measured medium is entered by the import of main flow pipeline 8 under pressure, flow into filter element cavity 13, screen pack 9 filter conventional filter such as containing the rag bar can't the impurity of filtering after, then flow out through the outlet of main flow pipeline 8, to be attached to attachments such as rag bar on the screen pack 9 when cleaning piston plate 12 pumps and draw together and remove, and make it enter dirt storage room 10 with gravitational settling, this process has been finished on-line filtration.The surface of described cleaning piston plate 12 is equipped with a plurality of filter openings, above the upper limit position of cleaning piston plate 12, the top that is described screen pack 9 arranges shunt valve 6, its objective is and guarantee under the blocked extreme operating condition of the screen pack 9 that communicates with main flow pipeline 8 outlet, can guarantee that filter works all the time, normal circulation is arranged in the main flow pipeline.
After measured medium is through filter element cavity 13, the dirt that produces or impurity (such as rag etc.) are blocked the edge of screen pack 9 mesh that rest on filter element cavity 13, when being stopped up by dirt and impurity such as screen pack 9 mesh, then the filter pressure reduction of importing and exporting two ends increases (Pressure gauge 7 and 7 ' the two pressure difference), need allow this moment limiting lock tight rope 4 and limiting lock tight rope hook 5 break away from, on handle 3 operating sides of raising one's hand, drive down motion of cleaning piston plate 12 by connecting rod 1, dirt and impurity on screen pack 9 mesh of filter element cavity 13 can be scraped, make filter recover normal operation (pressure difference at filter two ends reduces).The dirt that is scraped and impurity fall in the dirt storage room 10 under Action of Gravity Field.Stop up such as special obstinate dirt or the impurity a plurality of filter openings with the surface of cleaning piston plate 12, then can pass into the compressed air sedimentation of dirt or impurity can being blown off at air inlet 16, fall in the dirt storage room 10.Can not reduce such as filter two ends pressure reduction, show that then dirt storage room 10 is full, need open blowdown flat gate valve 11 this moment, automatically empty dirt and impurity in the dirt storage room 10, after cleaning piston plate 12 arrival lower positions are finished and removed contamination, need press down the operating side of handle 3, cleaning piston plate 12 is reset to upper limit position under the drive of connecting rod 1, by limiting lock tight rope 4 and limiting lock tight rope hook 5, lock spacing.Whole filtration, blowdown, the process of removing contamination all can be finished online, need not termination of pumping, and filter effect is remarkable, and it is very convenient to operate.
