The specific embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
Like Fig. 1～shown in Figure 10: the pocket type filter core that is used on the filter comprises filter course 1, skeleton 2, sealing flange 3, end socket 4, flange 5, handle 6, body 7, grid hole 8, fold 9, blade 10 etc.
Embodiment one: a kind of pocket type filter core that is used on the filter can be used for single bag of bag filter, multi-bag type filter, combination and system's formula filter.
Like Fig. 1～shown in Figure 5, said filter core comprises filter course 1, at the filter course 1 inner skeleton 2 that is used to support filter course 1 of placing, on the top of filter course 1 sealing flange 3 is installed, and on sealing flange 3, offers water inlet, in the bottom of filter course 1 end socket 4 is installed; Said filter course 1 is folded to form some folds 9, and said fold 9 laterally evenly distributes along filter course 1, and the distance of highest point and lowest part is 8～40mm.
Embodiment two: a kind of pocket type filter core that is used on the filter can be used for single bag of bag filter, multi-bag type filter, combination and system's formula filter.
Like Fig. 6～shown in Figure 10, said filter core comprises filter course 1, at the filter course 1 inner skeleton 2 that is used to support filter course 1 of placing, on the top of filter course 1 sealing flange 3 is installed, and on sealing flange 3, offers water inlet, in the bottom of filter course 1 end socket 4 is installed; Said filter course 1 is folded to form some folds 9, and said fold 9 vertically evenly distributes along filter course 1, and the distance of highest point and lowest part is 8～40mm.
Like Fig. 3, shown in Figure 8; In order to guarantee the excellent sealing between filter core and the filter cylinder; The outer end of said sealing flange 3 is provided with step flange 5, and the outside step surface of the outer wall of flange 3 and flange 5 has formed the sealing surface between sealing flange 3 and the bag filter cylindrical shell.
Like Fig. 1, Fig. 5, Fig. 6, shown in Figure 10, renew cartridge more is provided with handle 6 in the upper end of said sealing flange 3 for ease.
Like Fig. 3, shown in Figure 8, in order to make the bottom that needs filter liquide to be dispersed to filter core uniformly, said skeleton 2 is connected to form by the body 7 of multistage both ends open; Can be according to the size of filter core; Three sections or above body 7 are set, and the upper end of body 7 is little, the lower end is big, and the tube wall of body 7 is provided with some grid holes 8; The blade 10 that a plurality of radial downward-sloping settings are arranged along the radial equipartition of body 2 in the lower ending opening of said body 2; Can play guide functions, and make liquid to be filtered in body 7, produce eddy current, make liquid to be filtered evenly be attached to the surface of filter core;
According to the intrinsic shape of filter core, the cross sectional shape of body 7 can be square, circle or rhombus;
Said skeleton 2 can adopt macromolecular material (PP, PE, PET, PTEE, PPC, PPEE, PTFE synthetic plastic and natural plastics etc.), and all hard and soft material (nonmetal) etc. are processed; High-low temperature resistant, chemical resistance is good, adopts the combined type design, and flexible combination satisfies the instructions for use of all bag filters, and with low cost;
The skeleton 2 of this structure can make and need filter liquide effectively buffering and assembled arrangement embed the deep layer that needs filter liquide when getting into filter core, effectively to relax the filter element filtering layer, and make fluid produce eddy current the sidepiece of filter core and the impact of bottom when getting into filter core; Making needs filter liquide evenly to be attached to cartridge surface; Stop the inhomogeneous of filter efficiency, improve filter efficiency and product service life greatly, make pollutant holding capability be far longer than common filter core; Effectively prolong filtration time; Effectively improve pollutant holding capability and fit closely, reduced the frequency of changing, greatly reduce production cost in the harmony and the media attachment property of filter course 1.
Said filter course 1 by the pre-filtering layer, go deep into filter course and the fine filtering layer is composited, sandwich construction has ideally substituted support and the booster action of filter basket in bag filter.Filter liquide is when getting into filter course 1; By large, medium and small particle respectively attached to the pre-filtering layer of filter course 1, go deep into filter course and fine filtering layer; Filtrating is carried out organic cloth stream, and it is uneven respectively to reduce liquid filtering, inefficient phenomenon; Rely on simultaneously flow medium and medium to collide again, take in three filter courses filter residue and sewage draining exit.
For increase receive dirty space, prolong filtration time, said filter course 1 can be according to filter core intrinsic shape condition, with fold 9 be designed to vertically, horizontal, lantern shape and fan-shaped folding ripple etc. are multi-form.The filter core of this kind structure is higher than the filter efficiency of common filter bag/filter core, pollutant holding capability is big, and service life is big more than 5 times, and filter area is 3 times of common filter bag/filter core.
The operation principle of the utility model: fluid to be filtered gets into filter interior from the inlet of filter; Filter by the entering of the water inlet on the sealing flange on filter core top; The solid impurity particle is blocked in the filter core, and clean fluid passes through filter core, discharged by filter outlet.The utility model has been cancelled bracing frame and filter basket of common filter bag etc.; Fluid to be filtered directly gets into from water inlet; From inside to outside filter by filter course; Liquid to be filtered forms the vortex equiblibrium mass distribution in the filter course of filter core through skeleton, carry out integral filter work by filter course after, the liquid after the filtration is discharged by filter course; Liquid to be filtered effectively and the balanced continuous helical eddies of water formula skeleton that passes through; Vary in size and medium that viscosity is different and impurity are balanced attached in the filter course; When the pressure reduction that filters element reaches the maximum permission pressure difference of setting; During setting value that perhaps time is up, can be easily renew cartridge more.
