Definitions
- the group of inventions relates to filtering devices for purifying liquids, mainly drinking water, intended for use in filters for purifying liquids in domestic conditions, mainly in jug type filters and can be used for purification of drinking water and other liquids for domestic use, in the medical and other industries .
- a device for filtering water is known from the prior art (US Pat. No. 5,002,665, published on 26.03.1991 g, IPC B01 D24 / 00), including a filter insert (1) filled with filter material having the shape of a glass that is closed by a lid (3) on top, in the base of which there are outlet openings (5), which are closed on top by a mesh (9) of fusible plastic fibers, which can be welded to the base (pages 1, 2 of the description of the invention; FIGS. 1, 2).
- This device is quite difficult to manufacture and has a small flow surface, which leads to a decrease in the filtration rate.
- Known filter module for cleaning liquid consisting of a housing (2) made in the form of a glass with side walls and a base (6) with outlet openings (9) and a cover with openings for liquid inlet.
- a housing made in the form of a glass with side walls and a base (6) with outlet openings (9) and a cover with openings for liquid inlet.
- a mesh is arranged between the material and the base of the housing, made in the form of a flat disk welded to the base.
- the mesh is made of a nonwoven material, for example polypropylene (page 1 of the description of the invention; figure 2), (US patent N25,049,272, publ. 09/17/1991, IPC B01 D24 / 14).
- it is necessary to additionally fix the grid on the basis of the module.
- the closest analogue is the filter cartridge (1) according to US patent 6,099,728, publ. 08.08.2000g, IPC B01D27 / 02, filled with granular filtering material, made in the form of an open cup, which can be closed by a lid having side walls (3) and a bottom (1) with outlet openings (2) closed by a fabric insert (12) with a plastic frame (11) (page 2 of the description of the invention, Figs. 1, 2), wherein the mesh size in the tissue is in the range of 50 to 300 microns, preferably 80-200 microns (page 1 of the description of the invention). Outlets located at the bottom of the cartridge have a limited flow area, which leads to a decrease in the filtration rate, i.e. to deterioration of product performance.
- the closest analogue to the method of manufacturing a filter cartridge is a method of manufacturing a casing or part of the finish with a directly cast fastener according to US patent 6,887,413, publ. 05/03/2005, IPC B29C45 / 14, including the placement of a workpiece, which is a decorative part with a layer of wood veneer or a part of sheet metal or a non-woven coating on a substrate, etc., in at least a split mold for injection molding, closing the mold and thereby ensuring the cutting (cutting) of the part from the workpiece to an exact shape, filling the mold cavity with the molten casting composition by injection under pressure, and after solidification of the composition, removing the product from the mold.
- this method when using fibrous materials with a small fiber diameter as a preform, the problem of cutting the preform arises.
- the overall objective of the proposed group of inventions is to create a reliable design with high performance while simplifying the manufacturing technology of the product.
- the technical result from the use of the proposed group of inventions is to increase the rate of liquid filtration by increasing the flow surface while increasing the efficiency of liquid purification.
- the bottom is made with the possibility of using a permeable material reaching the outer edge of the side walls and made of fibers with a sufficiently small diameter Ohm, which allows the use of filtering material, including powder particles
- the entire area between the outer and inner edges of the walls along the perimeter of the bottom is a composite of a polymer and water-permeable material, and the fact that they use a water-permeable material containing fibers with a diameter of 0.5 microns or more, preferably 2-20 microns, and the use of a permeable material with a thickness of 0.02 mm to 3 mm, preferably 0.04 mm to 2 mm, and even more preferably 0.05 mm to 0.3 mm, and that use permeable material made of polyester fibers or
- Figure 1 shows a General view and a bottom view of the filter cartridge, in which the side walls are made in the form of a cylindrical surface
- Figure 2 shows a General view and a bottom view of the filter cartridge, in which the side walls are made in the form of a cylindrical surface with a V-shaped groove
- Fig. 3 shows a bottom view of a filter cartridge in which radially directed stiffeners are made, and the side walls are in the form of a cylindrical surface
- FIG. 4 shows a bottom view of a filter cartridge in which radially directed stiffeners are made and the side walls are in the form of a cylindrical surface with a V-shaped groove.
- FIG. 5 shows a general view and a bottom view of a filter cartridge in which stiffeners are made on a conical surface.
- FIG. 6 shows a general view and a bottom view of the filter cartridge, in which the permeable material is made in the form of a corrugation
- FIG. 7 shows a general view and a bottom view of the filter cartridge, in which the permeable material located between the stiffeners has a surface area greater than the cross-sectional area between the stiffeners.
- FIG. 8 is a perspective view of a jug type filter with a filter cartridge inside.
- FIG. 9 shows a diagram of a mold.
- a significant feature of the inventive filter cartridge is the implementation of the bottom of a permeable material reaching the outer edge of the side walls and made of fibers with a sufficiently small diameter of the claimed method.
- the use of a water-permeable material made of thin fibers makes it possible to provide high gas permeability and water permeability to the output filter, which is the bottom of the filter cartridge by increasing the total flow area, i.e. increase the rate of liquid filtration and, in addition, use a finer sorbent in the filter cartridge, for example, activated powdered carbon with a particle size of less than 50 microns (mainly 20 microns or less), which in turn leads to an increase in the degree of purification of the filtered liquid.
- the filter cartridge 1 (figure 1), made in the form of a glass and filled with filter material 4, consists of side walls 2, which can be made, for example, in the form of a cylindrical surface (figure 1) or in the form of a cylindrical surface with V- shaped groove 7 (figure 2), which serves to fix the filter cartridge in the receiving tank for the water to be cleaned and the bottom 3.
- the bottom 3 of the filter cartridge 1 is made entirely of permeable material 5, made of fibers with a sufficiently small diameter reaching the outer edge of the lateral walls 2 so that the region 6 between the outer and inner edges of these walls 2 is a composite of polymer and permeable material 5 (type I 1 of figure 1).
- a water-permeable material 5 that transmits water and traps particles of filter material for example, non-woven material is used - polypropylene or the like with a fiber diameter of 10 microns or woven material, for example, a mesh of polyester fibers with a fiber diameter of 20 microns, 0.3 mm thick.
- the bottom 3 of the filter cartridge 1 can be made of either a flat permeable material 5 (Fig. 1, 2) or a corrugated permeable material 5 (a thinner or compressible material is used) (Fig. 6).
- the water-permeable material 5 can be made, for example, of several layers, which allows to reduce the hydraulic resistance and, as a consequence, increase the fluid flow rate and, in addition, at least one of the layers can be made of a material with certain properties, for example, a bactericidal material or sorption material or ion exchange material.
- the bottom 3 of the filter cartridge 1 can be made with stiffeners 8, which can protect the permeable material from accidental mechanical stress and to give the design reliability when the filter cartridge 1 is large. Moreover, the area of leakage between the stiffeners is much larger than in the closest analogue, including due to the implementation of stiffeners 8 of a smaller size. Stiffening ribs 8 are (as well as region 6, between the outer and inner edges of the walls 2 along the perimeter of the bottom 3) a composite of polymer and permeable material 5, which is a more durable material. In this regard, stiffeners 8 occupy a smaller surface area of the bottom 3 of the filter cartridge 1 than the surface area of the leakage formed by the permeable material.
- Stiffening ribs 8 can be made, for example, radial (Fig. 3, 4) or on a conical surface (Fig. 5).
- a water-permeable material 5, between the stiffeners 8, can be made with a surface area greater than the cross-sectional area between the ribs, as shown in Fig.7. Since a water-permeable material is easily formed, between the closed mold elements inevitably folds of material are formed, which are filled with polymer material: i.e. sections of polymer material are formed between the convex sections of the permeable material, which also allows, due to the increase in the flow surface, to increase the rate of liquid filtration.
- filter material 4 for example, activated carbon granular particles (activated granular carbon) and / or ion-exchange polymer granules (ion-exchange resin) and powder particles with a size of less than 50 microns (activated powder carbon with a particle size of 20 or less microns) and / or fibrous particles with a fiber diameter of less than 50 microns (ion-exchange polymer fibers, for example, ion-exchange polyacrylonitrile fibers with a fiber diameter of 15-20 microns).
- the filter cartridge 1 can be closed on top by a cover 9.
- the filter cartridge can be used in a device for purifying a liquid, mainly water, for example, in a filter such as a jug.
- a filter cartridge and a device for purifying a liquid, for example, water operates as follows: a filter cartridge 1, filled with filter material 4 and closed with a lid 9, is installed in a receiving tank for the water to be purified 10 (Fig. 8).
- the receiving tank 10, made in the form of a funnel with a filter cartridge 1, is installed in a tank for purified water 11, made in the form of a jug.
- the raw water through the holes in the cover 9 enters the filter cartridge 1 and passes through the filter material 4, after which purified water passes through the bottom 3 of the filter cartridge and enters the tank 11, while small particles of filter material (sorbent) do not fall into the purified water. Drain purified water is carried out by tilting the device for water purification.
- a blank 3 is fed into a releasable mold 1 (Fig. 9), in which region 2 is formed, which can be, for example, a permeable material with a fiber diameter of 0 , 5 microns, for example, non-woven material - polypropylene or the like with a fiber diameter of 10 microns or woven material, for example a mesh of polyester fibers with a fiber diameter of 20 microns, a thickness of 0.3 mm
- the mold 1 is closed and filled with molten polymer (for example polypropylene or polyethylene) by injection under pressure.
- the part is felled to a predetermined shape, which is conducted along the felling zone 4.
- the operation of cutting the part to a predetermined shape and the operation of removing the finished product are combined and carried out simultaneously.
- the workpiece 3 tape of a permeable material
- Region 2 in the mold 1 is formed due to the steps (for example, 0.2-0.6 mm thick) of the molding elements of the mold in contact with the workpiece 3, which allows the process of cutting parts in zone 4 using a workpiece made of permeable material with a sufficiently small fiber diameter.
- the molten polymer in individual elements of the part for example, the cutting area, stiffeners, the area between the outer and inner edges of the side walls, can close the workpiece 3 on one side or close it on both sides by performing the aforementioned ledges of the molding elements of the mold on one side of the workpiece 3 or on both sides.
- the sequence of operations for cutting parts after the operation of filling the mold with molten polymer allows you to implement the process of cutting parts.
- the combination of a change in the sequence of operations and the formation of a cutting zone in a region specially made in the mold makes it possible to process a permeable material with a sufficiently small diameter of fibers of different thicknesses within the prescribed dimensions, and the combination of the operations of cutting a part and extracting the finished product simplifies the manufacturing process.
