Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
A kind of monoblock type bag type filter, as shown in Figure 2, comprise filter shell 1 and be welded on the filter core 2 among filter shell, the foldable assembly 21 that described filter core gives a discount shaping by filtering material and inner support tube 22, outer support pipe 23 form, and described inside and outside stay pipe is PP plastics.The structural representation of inner support tube 22, outer support pipe 23 is shown in Fig. 3, Fig. 4 respectively.
The filtering material of described foldable assembly from outside to inside, is namely made up of four layer materials from the downstream of swimming over to of filtering: prop up overfill protection polypropylene non-woven layer of cloth, filtration polypropylene non-woven layer of cloth, polyethersulfone millipore filter layer and lower support protection polypropylene non-woven layer of cloth successively.
The both sides of described foldable assembly impale, and by solder design, form a tubular structure, as shown in Figure 5, foldable assembly after being completed by weld seam is set between inner support tube and outer support pipe, described interior and outer support pipe is distributed with the hole 3 that filtered fluid can be made to flow into, as shown in Figure 6.
Pre-filtering component layers 6 is filled in space between described filter core 2 and filter shell 1.The filtered fluid entering filter shell, by the filtration of described pre-filtering component layers 6 and described foldable assembly 21, can flow out from the downstream of inner support tube and lower ending opening 221.
Described filter core two ends respectively by upper end cover 41 and bottom end cover 42 hot melt end-blocking, as shown in Figure 9.Described upper end cover and bottom end cover are the thin lid that radius is more than or equal to described foldable assembly radius; The upper end of the end face of described foldable assembly and inner support tube can seal by described upper end cover completely; The centre of described bottom end cover is provided with the opening 421 corresponding with inner support tube lower ending opening 221, the bottom surface of described foldable assembly can be sealed completely, but its opening 421 can make the filtered fluid in inner support tube 22 flow out.The structural representation of upper end cover 41 and bottom end cover 42 is shown in Fig. 7, Fig. 8 respectively.
The top of described filter shell has opening 11, bottom all has opening 12, when described filter core is arranged in filter shell 1, space 5 is left, so that the open top 11 that filtered fluid leads to filter housing flows in filter shell 1 between the open top 11 of described filter shell and the upper end cover 41 of described filter core; The inside edge of the bottom opening 12 of described filter shell and the bottom end cover 42 of described filter core are tightly connected, the bottom opening 12 of described filter shell is corresponding with the position of the opening 421 of the bottom end cover of described filter core, so that the filtered fluid that the opening of bottom end cover 421 flows out flows out from filter shell 1.
When using described monoblock type bag type filter, the open top 11 that filtered fluid leads to filter housing 1 flows in filter shell, because the end face of foldable assembly and the upper end of inner support tube seal by upper end cover 41 completely, the bottom surface of foldable assembly seals by bottom end cover 42 completely, the edge of the bottom opening 12 of filter shell and the bottom end cover 42 of described filter core are tightly connected, therefore the filtered fluid flowed in filter shell 1 infiltrates in foldable assembly 21 by the hole 3 of distribution on outer support pipe 23, penetrate through four layer materials of foldable assembly successively: above prop up overfill protection polypropylene non-woven layer of cloth, filter and use polypropylene non-woven layer of cloth, polypropylene non-woven layer of cloth is used in polyethersulfone millipore filter layer and lower support protection.
Described upper overfill protection polypropylene non-woven layer of cloth can be played a supporting role; pre-filtering effect can be played again; the filtering accuracy of described filtration polypropylene non-woven layer of cloth is 0.1 micron to 60 microns; bulky grain solid impurity can be retained; the polyethersulfone membranes in downstream is played a protective role, the service life of downstream poly (ether sulfone) film can be extended simultaneously.The filtering accuracy of described polyethersulfone millipore filter layer is 0.03 micron to 5 microns, can filter and retain the little impurity of particle diameter, the size of bacterium can be reached, by the filtration of different filter course, metal ion, the solid impurity that finally can be removed in filtered fluid, disinfectant, peculiar smell etc., remove bacterium and microorganism simultaneously and produce pure liquid.
When can fill pre-filtering component layers 6 in the space 5 between described filter core 2 and filter shell 1, the filtered fluid flowed in filter shell also needed first through the pre-filtering of pre-filtering component layers 6 before penetrating into four layer materials of foldable assembly.
Described pre-filtering component layers is activated carbon powder or activated carbon block or ion exchange resin, or activated carbon powder, activated carbon block, ion exchange resin wherein two or three mixing.
Also can coated NACF 7 outside described filter core, as shown in Figure 10.NACF is threadiness, and fiber is covered with micropore, and it is higher several times to tens times in atmosphere than granular activated carbon to organic gas adsorption capacity, high several times in aqueous, the rate of adsorption also soon hundreds of times.
Can only coated NACF 7 outside described filter core 2, also can, after coated NACF 7, continue in the space outside the filter core 2 of coated NACF and between filter shell 1 to fill pre-filtering component layers 6.Therefore the filtration in inflow filter shell is first through the pre-filtering of pre-filtering component layers 6, or the filtration of NACF 7, or just enters four layer materials of foldable assembly 21 after the double medium filtration of pre-filtering component layers 6 and NACF 7.
Liquid within four layer materials penetrating into foldable assembly 21 is through filtering layer by layer, infiltrated in inner support tube 22 by the hole 3 of distribution on stay pipe 23 inside and outside in foldable assembly 21 and form the liquid after filtering, liquid after filtration flows out from the opening 421 of the bottom end cover of filter core, and the bottom opening 12 through filter shell flows out from filter shell 1.
Open top 11 and the bottom opening 12 of described filter shell 1 are connected to interface, be convenient to be connected with the pipeline of filtered fluid, top and bottom described in this patent, top and bottom, only as the name that patent describes, the filter actual used time, the one end passing into filtered fluid is upper end, one end of liquid after outflow filter is lower end, and filter does not need vertical placement.
The above; it is only preferred embodiment of the present invention; not any pro forma restriction is done to the present invention; any those skilled in the art; do not departing within the scope of technical solution of the present invention; according to technical spirit of the present invention, any simple amendment that above embodiment is done, equivalently replace and improve, within the protection domain all still belonging to technical solution of the present invention.
