Description
Technical field
The present invention relates to a kind of filter element fast assembling disassembling structure, the dismounting of the filter of the automatic back-flushing function that is mainly used in using in Ship's Ballast System.
Background technology
The filter using in Ship's Ballast System, the filter with automatic back-flushing function is adopted in a large number owing to having automatic back-flushing function, and in order to strengthen filter effect and to increase filter area, particularly the filter core usage quantity of large flow filter increases greatly, these filter cores stop up and damage phenomenon owing to using to have unavoidably in dirty, adverse circumstances, therefore need to clean or renew cartridge more, so just brought a large amount of disassemble and assemble work amounts.
The filter core mounting means of the domestic and international filter in use is mainly to use some bolts and platen to fix at present, time and effort consuming when assembling-disassembling bolt, the stainless steel bolt of dismantling is owing to can not find or cannot take out in the little space of easily falling into filter of volume, cause filter completely knocked down could to be taken out, cause that labour intensity is large, maintenance time is long; And due to work under bad environment, maintenance personal stays in this service clearance for a long time, health is produced to harmful effect.
Meanwhile, assembling-disassembling bolt, platen need use specific purpose tool, and because platen is thin yielding, the out-of-flatness causing in unloading process makes the frictional force of itself and blowdown arm suddenly big or suddenly small; And the corrosion meeting of bolt causes unloading, the loosening meeting of bolt causes blowdown arm to turn motionless, causes filter cisco unity malfunction.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide a kind of with low cost, time saving and energy saving, convenient and swift, operating efficiency is high, use simple tool can easily complete the filter element fast assembling disassembling structure of dismounting, this structure can ensure that automatic backwashing filter is reliable, even running.
Object of the present invention is achieved through the following technical solutions: a kind of filter element fast assembling disassembling structure, comprise the top tray, support tube, the lower tray that connect successively, and be fixed on the some filter cores between top tray and lower tray by the filter core installing hole being arranged in top tray and lower tray; In the filter core installing hole of described top tray, be provided with annular groove, earless springhole back-up ring is set in annular groove.
Further, described top tray, lower tray, support tube are hollow circuit cylinder body structure, and described filter core installing hole arranges with the even interval of cylinder end face of top tray and lower tray.
Further, the correspondence position of described support tube inner surface and top tray and lower tray is provided with locating piece, is also provided with hole for hoist on the locating piece in support tube.
Further, the junction of described top tray and lower tray and support tube is provided with step surface and seal groove, is provided with sealing ring in seal groove.
Further, the filter core structure of mounting hole of described top tray is 60 °, two sides chamfering conical bore and is connected to cylindrical hole, annular groove, cylindrical hole wherein.
Further, the upper and lower two ends of described filter core are provided with seal groove, are provided with sealing ring in groove, and being provided with in the filter core installing hole that positioning step is positioned at lower tray with lower tray installation place.
Further, described filter core adopts stainless steel filter core.
The invention has the beneficial effects as follows: earless springhole back-up ring is with low cost, uses simple tool easily to split out when dismounting; While packing into, push away earless springhole back-up ring with have gentle hands and can push annular groove, in annular groove, do not need to use specific purpose tool by himself elastic card, without assembling-disassembling bolt, dismounting is time saving and energy saving, convenient and swift; Earless springhole is greater than filter core with back-up ring diameter aperture is installed, and can not fall into filter interior, and filter core installing hole two sides is processed with 60 ° of chamferings, can make filter core extract smoothly and pack into, has greatly improved operating efficiency, has reduced labour intensity; Top tray working face is smooth smooth, and frictional force is little, has ensured that automatic backwashing filter is reliable, even running.
