Quick mounting and dismounting structure for filter cores of filter

Abstract

The invention discloses a quick mounting and dismounting structure for filter cores of a filter. The quick mounting and dismounting structure includes an upper tray, a support cylinder and a lower tray which are connected in sequence, and also includes a plurality of filter cores fixing between the upper tray and the lower tray through filter core mounting holes arranged on the upper tray and the lower tray; the filter core mounting holes of the upper tray are each internally provided with an annular groove, and each annular groove is internally provided with an earless elastic hole baffle ring. The quick mounting and dismounting structure is low in cost, and adopts simple tools during dismounting; hand pushing is performed during mounting, no dedicated tools are required, bolts are not required to be mounted or dismounted, and mounting and dismounting save time and labor and are convenient and fast; the diameter of the earless elastic hole baffle rings is larger than the diameter of the filter core mounting holes, so that the baffle rings do not fall into the interior of the filter; two faces of each filter core mounting hole are each processed with a 60-degree chamfer, so that pulling-out and mounting-in of the filter cores are smooth, the work efficiency is greatly improved, and the labor intensity is reduced; the working surface of the upper tray is flat and smooth, the friction force is small, and reliable, smooth and steady operation of the automatic backwashing filter is ensured.

Description

technical field [0001] The invention relates to a quick disassembly and assembly structure of a filter core, which is mainly used for the disassembly and assembly of a filter with an automatic backwashing function used in a ship's ballast water system.

[0002] The filter used in the ship's ballast water system, the filter with automatic backwash function is widely used because of its automatic backwash function, and in order to enhance the filtering effect and increase the filtering area, especially the number of filter elements used in large flow filters Greatly increased, these filter elements will inevitably be clogged and damaged due to use in dirty and harsh environments, so the filter elements need to be cleaned or replaced, which brings a lot of disassembly and assembly workload

[0003] At present, the installation method of the filter element of the filter used at home and abroad is mainly fixed by a number of bolts and a pressure plate. It is time-consuming and laborious to disassemble the bolts. The removed stainless steel bolts are easy to fall into the gap of the filter due to their small size. It cannot be taken out, so the filter must be disassembled before it can be taken out, resulting in high labor intensity and long maintenance time; and due to the harsh working environment, maintenance personnel stay in this maintenance space for a long time, which will have adverse effects on the body

[0004] At the same time, special tools are required to disassemble the bolts and pressure plate. Since the pressure plate is thin and easy to deform, the unevenness caused during the disassembly process makes the friction between the sewage arm and the sewage arm fluctuate. The corrosion of the bolts will make it impossible to remove. The looseness of the bolts will cause the sewage arm to not rotate, resulting in the filter not working properly
