Description

Combined type filter core, filter core subassembly, water purification system

Technical Field

The invention relates to the technical field of water treatment, in particular to a composite filter element, a filter element assembly and a water purifying system.

Background

The water purifying product is a water purifier, which is water treatment equipment for carrying out deep filtration and purification treatment on water according to the use requirement of the water. The water purifier can effectively filter rust, sand and stone, colloid and adsorb residual chlorine, smell, different colors, pesticides and other chemical agents in water. Can effectively remove bacteria, germs, toxins, heavy metals and other impurities in the water. The use is very common in both civilian and commercial applications.

The chinese patent application number 2023212511271 discloses a filter cartridge and a water purification device, as shown in fig. 1-3, the filter cartridge comprises: a housing; a raw water inlet; a waste water outlet; a purified water outlet; a first filter unit, a second filter unit and a containing assembly loaded with a scale inhibitor, which are arranged in the shell; the raw water inlet is communicated with the raw water end of the second filtering unit, the waste water end of the second filtering unit is communicated with the waste water outlet, and the purified water end of the second filtering unit is communicated with the purified water outlet; the accommodating component is positioned at the upstream of the raw water end of the second filtering unit, so that water flowing in from the raw water inlet flows into the raw water end of the second filtering unit after passing through the accommodating component; the first filter unit is located upstream of the raw water end of the second filter unit or the first filter unit is located downstream of the purified water end of the second filter unit.

In the prior art, the filtering precision of the outer ring filter layer and the filtering precision of the inner ring filter layer of the filter element are basically the same, and in order to ensure the filtering effect, the filtering precision of the outer ring filter layer and the filtering precision of the inner ring filter layer are both higher. When the filter element is used for a long time, large-volume impurities such as colloid cannot pass through the outer ring filter layer with high filtering precision, so that the outer ring filter layer of the filter element can block a large amount of colloid to cause the filter element to be blocked under most conditions, and the filter element needs to be replaced at the moment. However, the inner ring filter layer of the filter element still maintains the filtering capability under the condition, and great waste is caused if the whole filter element is replaced.

In addition, the scale inhibitor in the prior art is placed in a special space arranged in the shell or the end cover, namely at the front end of the raw water channel of the filter element, and in the structure, the scale inhibitor is easy to leak. In order to prevent leakage of the scale inhibitor, relevant parts are required to be installed in the shell or the end cover, so that the assembly difficulty is improved, and the manufacturing cost is also improved.

Moreover, the prior art water purification system uses a carbon tank to remove chlorine, which can completely remove chlorine in raw water. However, on one hand, the carbon tank is polluted greatly when the core is replaced, and on the other hand, if the purified water does not contain chlorine, the water quality is easy to become smelly and is not suitable for the requirement of sanitary water.

Detailed Description

For a further understanding of the present invention, the present invention will be described in detail with reference to the drawings and examples.

The structures, proportions, sizes, etc. shown in the drawings are shown only in connection with the present disclosure, and are not intended to limit the scope of the invention, since any modification, variation in proportions, or adjustment of the size, etc. of the structures, proportions, etc. should be considered as falling within the spirit and scope of the invention, without affecting the effect or achievement of the objective. Also, the terms "upper", "lower", "left", "right", "middle", and the like are used herein for descriptive purposes only and are not intended to limit the scope of the invention for modification or adjustment of the relative relationships thereof, as they are also considered within the scope of the invention without substantial modification to the technical context.

In one embodiment, the present invention provides a composite filter element, which includes a first filter layer 102, an activated carbon fiber layer 106, and a second filter layer 104 sequentially wound on a central tube 101 from inside to outside. The first filter layer 102 and the second filter layer 104 may be the same filter layer, i.e., an integral design. The first filter layer 102 and the second filter layer 104 may also be different filter layers, i.e., a split design.

The activated carbon fiber layer 106 has dispersed thereon particles 107 of a scale inhibitor or bacteriostatic agent. The scale inhibitor or bacteriostatic agent particles 107 become trapped within the activated carbon fiber layer 106 as the activated carbon fiber layer 106 is rolled.

In one embodiment, as shown in fig. 4, the present invention provides a composite filter element, which includes a first filter layer 102, an activated carbon fiber layer 106, and a second filter layer 104 sequentially wound on a central tube 101 from inside to outside, wherein the filtering precision of the second filter layer 104 is lower than that of the first filter layer 102 and the activated carbon fiber layer 106.

The first filter layer 102 may have a smaller filtration accuracy than the activated carbon fiber layer 106, and the first filter layer 102 may intercept the dropped fibers.

In addition, the first filter layer 102 may also have a greater filtration accuracy than the activated carbon fiber layer 106.

Each filter layer forms different filtering gradients, so that the filter element filtering precision is ensured, the dirt receiving capacity of the filter element is improved, and the filtering service life is prolonged. The first filter layer 102 of the inner ring has higher filtering precision and can intercept the black fibers dropped by the activated carbon fibers. The second filter layer 104 with lower filtering precision is used for the outer ring, so that the colloid is prevented from sticking to the surface of the activated carbon fiber to influence the adsorption performance.

In this embodiment, the first filter layer 102 and the second filter layer 104 may be non-woven fabrics, or may be made of other materials, which is more mature in the prior art, and will not be described herein.

In one embodiment, as shown in fig. 5-6, the activated carbon fiber layer 106 is made of the transition filter layer 103 and the activated carbon fibers 105 disposed on the transition filter layer 103, which is well known in the art and will not be described in detail herein.

In this embodiment, in order to avoid the activated carbon fibers 105 from being broken during the winding process, the activated carbon fibers 105 need to be disposed on the transition filter layer 103 having a certain strength.

The transition filter layer 103 is used to connect the first filter layer 102 with the second filter layer 104.

In an alternative embodiment, the second filter layer 104 and the transition filter layer 103 may be separately arranged, that is, the second filter layer 104 and the transition filter layer 103 are not the same filter layer, and the filter accuracy of the second filter layer 104 is smaller than the filter accuracy of the transition filter layer 103, so as to form different filter gradients.

In an alternative embodiment, the second filter layer 104 is provided integrally with the transition filter layer 103, i.e. in this case the second filter layer 104 is the same filter layer as the transition filter layer 103, and in this case the filter accuracy of the second filter layer 104 is the same as the filter accuracy of the transition filter layer 103.

The transition filter layer 103 may be part of the first filter layer 102, i.e. at the end of the first filter layer 102.

The transition filter layer 103 may also be part of the second filter layer 104, i.e. at the beginning of the second filter layer 104.

The transition filter layer 103 may also be a single filter layer, i.e. not integral with both the first filter layer 102 and the second filter layer 104, which is wound after the first filter layer 102 and before the second filter layer 104.

In one embodiment, in order to avoid the activated carbon fiber layer 106 from being broken during winding, it is necessary that the activated carbon fiber layer 106 has a certain strength, and thus, the activated carbon fiber layer 106 is a coated activated carbon fiber or activated carbon paper. At this time, the activated carbon fiber layer 106 is directly wound after the first filter layer 102 is wound, and the second filter layer 104 is wound.

In one embodiment, the composite filter element further includes a peelable layer 203, the peelable layer 203 wrapping around the outside of the second filter layer 104 and being removable from the second filter layer 104. When the peelable layer 203 is blocked due to the adhesive colloid, the peelable layer 203 can be removed, so that the service life of the composite filter element is prolonged.

In one embodiment, as shown in FIG. 9, the second filter layer 104 terminates with a first constriction 201. The second filter layer 104 and the peelable layer 203 are separately arranged, that is, the second filter layer 104 and the peelable layer 203 are not the same filter layer, the second filter layer 104 is closed up and then cut along the cutting line 202, and then the peelable layer 203 is formed by winding 1-10 circles.

In this embodiment, the end of the peelable layer 203 may be sealed by the second sealing portion 204, or the peelable layer 203 may be prevented from being scattered by other ways.

The peelable layer 203 is not limited to the above manner, and the peelable layer 203 can be connected with the second filter layer 104 through a tearing line, so that when the peelable layer 203 is blocked by colloid, the peelable layer 203 can be torn off through the tearing line, which is relatively mature in the prior art, and is not described herein again.

The first and second sealing portions 201 and 204 may be any one of hot-press sealing, glue sealing, and ultrasonic welding sealing, which are more mature in the prior art and are not described herein.

In one embodiment, as shown in fig. 7-8, the activated carbon fiber layer 106 has scale inhibitor or bacteriostatic agent particles 107 dispersed thereon, the scale inhibitor or bacteriostatic agent particles 107 being encapsulated by the activated carbon fiber layer 106.

The scale inhibitor or the bacteriostatic agent is scattered on the activated carbon fiber layer 106 in the form of particles, the scale inhibitor or the bacteriostatic agent particles 107 are well wrapped in the activated carbon fibers by utilizing the characteristics of thicker, soft and easy deformation of the activated carbon fibers, and the deformation of the filter core is not caused, so that the leakage of the scale inhibitor can be prevented, and a space specially containing the scale inhibitor is not required to be arranged in a shell or an end cover.

The particle size of the scale inhibitor or bacteriostatic agent particles 107 is 0.05-2.0 mm so that they cannot pass through the first filter layer 102, the activated carbon fiber layer 106, and the second filter layer 104. Too fine powdered scale inhibitors or bacteriostats easily pass through the activated carbon fibers and the filter layers, accumulate on the inner ring filter layers to cause filter element blockage, or pass through the inner layers of the composite filter element to fail. For a scale inhibitor or a bacteriostatic agent with too large particle size, the thickness of the activated carbon fiber is insufficient for compressing and wrapping to form a bulge, so that the filter element is easy to deform and not rolled well.

In one embodiment, the scale inhibitor is a phosphate particle.

In one embodiment, the invention further provides a filter element assembly, as shown in fig. 10, which comprises a housing 301, a first end cover 302 and a second end cover 303, wherein the housing 301 is used for accommodating the composite filter element. The first end cap 302 is mounted to one end of the composite filter element and is sealingly connected to the end of the composite filter element. The second end cap 303 is mounted on the other end of the composite filter element.

In this embodiment, the second end cap 303 is provided with a raw water inlet 306 in sealed communication with the gap, and a purified water outlet 304 in sealed communication with the purified water end of the composite filter element. Raw water enters from a raw water inlet 306, is filtered by a composite filter element from outside to inside, and purified water enters the central tube 101 from a through hole formed in the central tube 101 and then flows out from a purified water outlet 304.

In one embodiment, the first end cap 302 and the second end cap 303 are detachably connected to the first cover 308 and the second cover 307, respectively. The second cover 307 is provided with connectors which are respectively communicated with the raw water inlet 306 and the purified water outlet 304 in a sealing way, thereby being convenient for being connected with a water purifier or other water purifying systems.

In one embodiment, the present invention further provides a water purification system, as shown in fig. 11, where the water purification system includes a plurality of filter element assemblies and a plurality of non-chlorine removal filter elements. The filter element assembly contains the activated carbon fiber layer 106, so that the raw water is filtered by the filter element assembly, and chlorine in the raw water is removed. The raw water is filtered by the non-chlorine removal filter element, and chlorine in the raw water is not removed, so that the purified water still has chlorine.

It should be noted that the non-chlorine removal filter element is only required to retain chlorine in raw water, which is mature in the prior art and will not be described herein.

The water purification system comprises a chlorine removal filtering mechanism and a chlorine retaining filtering mechanism which are connected in parallel. Part of raw water is filtered by a chlorine removal filtering mechanism, and the produced purified water contains no chlorine. Part of raw water is filtered by a chlorine-retaining filtering mechanism, and the produced purified water retains chlorine. The ratio of the purified water without chlorine to the purified water with the chlorine reserved can be adjusted according to the requirement, so that the chlorine content of the mixed purified water can meet the requirement.

In this embodiment, the plurality of filter element assemblies are connected in parallel with the plurality of non-chlorine removal filter elements, and the raw water is filtered by the filter element assemblies and the non-chlorine removal filter elements which are connected in parallel, and the purified water produced by the filter element assemblies and the purified water produced by the non-chlorine removal filter elements are mixed to form the purified water of the water purification system.

In one embodiment, there are a plurality of non-chlorine removal cartridges for the chlorine retention filter mechanism, the plurality of non-chlorine removal cartridges being arranged in parallel and/or in series. For a chlorine removal filter mechanism, there are a plurality of filter element assemblies, and a plurality of filter element assemblies are arranged in parallel and/or in series.

In another embodiment, there are multiple non-chlorine removal cartridges in the chlorine retention filter mechanism and one cartridge assembly in the chlorine removal filter mechanism. There may be one non-chlorine removing filter element in the chlorine retaining filter mechanism, and a plurality of filter element assemblies in the chlorine removing filter mechanism.

When the water consumption point is closer to a water plant, the chlorine content in raw water is higher, the number of filter element components in the chlorine removal filter mechanism is higher at the moment, the number of non-chlorine removal filter elements in the chlorine retention filter mechanism is smaller, and the purified water produced by the two filter mechanisms is mixed at the moment, so that the chlorine content can meet the use requirement.

Similarly, when the water consumption point is far away from the water plant, the chlorine content in raw water is low, the number of filter element components in the chlorine removal filter mechanism is low, the number of non-chlorine removal filter elements in the chlorine retention filter mechanism is high, and the purified water produced by the two filter mechanisms is mixed, so that the chlorine content can meet the use requirement.

When the user hopes that the chlorine content in the water is lower, the number of the filter element components in the chlorine removal filter mechanism is higher at the moment, and the number of the non-chlorine removal filter elements in the chlorine retention filter mechanism is lower, and the purified water produced by the two filter mechanisms is mixed at the moment, wherein the chlorine content can meet the use requirement.

When the user hopes that the chlorine content in the water is higher, the number of filter element components in the chlorine removal filter mechanism is smaller at the moment, and the number of non-chlorine removal filter elements in the chlorine retention filter mechanism is larger, and the purified water produced by the two filter mechanisms is mixed at the moment, wherein the chlorine content can meet the use requirement.

The invention and its embodiments have been described above by way of illustration and not limitation, and the invention is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present invention.
