Interlocking type water guide disk set

Abstract

The invention discloses an interlocking type water guide disk set which comprises a plurality of water guide disks and a plurality of water sealing assemblies, wherein the water guide disks are rotationally and mutually superimposed; each water guide disk comprises a disk-shaped body, a through hole running through the body along the axial direction, a plurality of annular holes disposed around the axial direction on the annular wall surface of the through holes, a plurality of locking parts which outwards extend from the disk surface at one side of the body and correspond to one end of each annular hole, a plurality of folding parts extending into the annular holes from the disk surface at the other side of the body and a positioning part which surrounds the annular holes and is inwards sunk respectively from the disk surfaces at two sides of the body; the positioning part is provided with at least one connecting hole running through the disk surfaces at two sides of the body; the water sealing assemblies are respectively and fixedly arranged on the positioning part on the water guide disk; and each water sealing assembly comprises two butting parts corresponding to the disk surfaces at two sides of the body and at least one guiding part which is arranged between the two butting parts and extends in the connecting hole. The set is more convenient to assembly and can be used for maintaining good water sealing effect between the water guide disk and a filter film.

Description

technical field [0001] The invention relates to a clamping device for a filter membrane, in particular to a set of interlocking water guide discs which are used for clamping the filter membrane and which can be stacked on top of each other. Background technique [0002] The patent No. ZL200510132492.0 patent "interlocking water guide plate group" which was first applied for and authorized by the inventor of this case discloses a clamping device that can tightly clamp the filter membrane in layers, including two It is a group of water guide pans for sandwiching a filter membrane, and each water guide plate is rotatably overlapped with the adjacent water guide plate, and each water guide plate has a body, which runs through an axial direction A central perforation of the body, a plurality of ring holes centered on the axial direction and passing through the body at equal intervals, a plurality of locking parts protruding from a disk surface of the body and respectively located...

Problems solved by technology

[0004] Although the gasket sandwiched between the surface of the water guide plate and the membrane surface of the filter membrane can indeed provide good watertight and leak-proof performance, but because the gasket and the water guide plate are only a general fit relationship, the relationship between the two is not fixed. In addition, in the actual assembly, the water deflectors must be rotated to assemble each other. In this way, the compressed washer is bound to be subjected to torsional shear forces in two different directions (one is clockwise, the other is clockwise). The other is counterclockwise), the size of these two shear forces depends on the friction between the gasket and the water guide plate and the filter membrane respectively. As we all know, the water guide plate and the filter membrane are not made of the same material. The relative coefficients of friction are also different, causing the gasket to bear two kinds of shearing forces with different sizes and directions, and because of the effects of these two different shearing forces, it is easy for the gasket to fall out of the ring groove of the water guide plate, or Serious deformation is caused, so that there will be a gap between the membrane surface of the filter membrane and the surface of the water guide plate, resulting in the loss of the watertight effect of the water guide plate group

[0005] In addition, since the two surfaces of the water guide pan must be respectively equipped with gaskets before they can be used, the gasket on the side of the water guide plate facing downward will naturally break away from the ring groove when the water guide plate is assembled vertically, so that the water guide pan is assembled in the opposite position. extremely inconvenient
