Abstract
The invention discloses a filter cylinder assembly of a high-pressure back-washing filter station. The filter cylinder assembly comprises a shell and a filter core, wherein the filter core is arranged inside the shell; an end cover is arranged at the upper end of the filter core; a screw plug is fixedly arranged on the inner side of the upper end of the shell; a press cover is arranged at the upper end inside the screw plug; a rapid locking mechanism is arranged between the press cover and the screw plug; the end cover extends into the lower end inside the screw plug; the end cover is located below the press cover; a concave hole is arranged in the end cover; a screw rod is arranged at the center of the press cover in a penetrating manner; and the lower end of the screw rod extends into the concave hole and props against the end cover. The filter cylinder assembly provided by the invention has the advantages in that the screw rod is screwed for a certain angle, so that the front end of the screw rod departs from an inner hole, and at the moment, the upper surface of a locking block departs from the upper surface for tightly pressing an annular groove; and the press cover is rotated for the certain angle, so that the locking block is aligned with a gap, and at the moment, the press cover can be taken out from the screw plug, and the screw rod is taken out with the press cover, so that the filter core is taken out from the shell, thus being very convenient to replace.
Description
Technical field
The present invention relates to a kind of high pressure backwash filter station, especially relate to a kind of cartridge assembly of high pressure backwash filter station.
Background technology
The fault that hydraulic system in use causes due to medium pollution accounts for the great majority of the system failure, along with the automation of the parts course of work is sent out long, hydraulic system part is more and more accurate, the unit failure rate requiring is more and more lower, therefore, improve the filtering accuracy of system media and prevent that in medium, fifth wheel enters the important means that workpiece is raising Hydraulic System Reliability.
The high pressure filtering station with backwashing function is to aim at the medium cleaning device that ensures the long-time reliability service of hydraulic system and establish.High pressure filtering station is installed on pumping plant outlet, and filter medium pollutant before medium enters work system comprises the metal chip that comes off, seal wear particle, paint, wearing and tearing powder, rubble grain, cinder etc.The cartridge assembly of filter station is most important parts, and cartridge assembly comprises shell and filter core, is provided with internal thread in shell, is provided with external screw thread on filter core, and filter core inserts in shell, and fixes with screw thread.In the time that needs are changed or keep in repair filter core, filter core need to be back-outed in shell, operate cumbersome.Be threaded simultaneously, easily cause and get rusty or stuck phenomenon generation.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of replacing cartridge assembly of high pressure backwash filter station easily.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of cartridge assembly of high pressure backwash filter station, comprise shell and filter core, described filter core is arranged in described shell, described filter core upper end is provided with end cap, the inner side, upper end that it is characterized in that described shell is fixedly installed screw plug, in described screw plug, upper end is provided with gland, between described gland and described screw plug, be provided with quick-connect mechanism, described end cap stretches into lower end in described screw plug, described end cap is positioned at described gland below, on described end cap, be provided with shrinkage pool, described gland center is equipped with screw rod, described screw rod lower end is stretched into shrinkage pool and is withstood on described end cap.
Described inner side, shell upper end is provided with internal thread, described screw plug is provided with external screw thread, described screw plug is screwed in described shell upper end, described quick-connect mechanism comprises the clamping block arranging on the breach of annular groove in the centre bore that is arranged on screw plug, inner side, screw plug upper end and gland, described annular groove communicates with described breach, described clamping block and described notch geometry match, and described clamping block falls in described annular groove.
The height of described annular groove is slightly larger than the thickness of clamping block, and the centre bore of described gland is provided with screw thread, and when screw rod withstands in described shrinkage pool through described centre bore, the upper surface of clamping block withstands on the upper inner side edge of annular groove.
Described breach is three, and evenly annular is distributed in inner side, screw plug upper end, and described clamping block is three, and evenly annular is distributed on gland.
Between shell and screw plug, be provided with the first sealing ring, between screw plug and gland, be provided with the second sealing ring, between screw rod and gland, be provided with the 3rd sealing ring.
On described end cap, be provided with draw ring, the convenient filter core that extracts.
Compared with prior art, advantage of the present invention is to turn screw rod certain angle, make the front end of screw rod leave endoporus, now the upper surface of clamping block leaves the upper surface that presses annular groove, then rotates gland certain angle, makes clamping block and notch alignment, now gland can be taken out in screw plug, screw rod is followed gland and is taken out, thereby filter core can be taken out in shell, and more renew cartridge is very convenient.
