Description

Filtering assembly

Technical Field

The utility model relates to the field of purified water, in particular to a filter assembly.

Background

Concentration polarization refers to the fact that in the separation process, a solution in a feed liquid is driven by pressure to permeate through a membrane, solutes (ions or solutes with different molecular weights) are trapped, and the concentration is higher and higher at the interface between the membrane and a bulk solution or in the area adjacent to the interface of the membrane; under the action of the concentration gradient, the solute is diffused from the membrane to the bulk solution to form a boundary layer, so that the fluid resistance and the local osmotic pressure are increased, and the solvent permeation flux is reduced. This will lead to a drastic decrease in the water production of the filter assembly and an increase in energy consumption.

Currently, most of the filtration modules are fed directly from the side edges of the membrane modules, which results in lower water feed rate of the current filtration modules, which results in serious concentration polarization phenomenon on the surface of the current membrane modules. And the water inlet mode ensures that the flow of water is shorter and the water production efficiency is lower.

As shown in fig. 1 to 8, the present embodiment provides a filter assembly 10, the filter assembly 10 including a purified water pipe 100, at least one raw water pipe 200, and at least one membrane assembly. The circumferential wall of the water purifying pipe 100 has at least one water purifying inlet 110. At least one raw water pipe 200 is provided along a length direction of the water purifying pipe 100, and is provided to the water purifying pipe 100 at intervals along a circumferential direction of the water purifying pipe 100 with at least one water purifying inlet 110. The peripheral wall of each raw water pipe 200 has a raw water outlet portion 210.

At least one membrane module is disposed in one-to-one correspondence with at least one raw water pipe 200, and forms raw water flow channels 310, respectively. Wherein the raw water flow path 310 is configured such that at least the raw water outlet portion 210 of the corresponding raw water pipe 200 is positioned therein to communicate with the corresponding raw water pipe 200. Wherein each raw water flow path 310 is wound along the circumferential direction of the water purifying pipe 100, and a winding gap formed at the outside thereof is configured as a water purifying flow path 320; wherein each of the purified water flow channels 320 communicates with the purified water pipe 100 through the purified water inlet portion 110 located therein.

In the present embodiment, the water purifying pipe 100 serves to introduce external purified water into the filter assembly 10 and discharge the purified water into the purified water flow path 320 through the purified water inlet portion 110. In the present embodiment, clean water refers to water that has not been filtered by the filter assembly 10, that is, clean water is water before filtration by the filter assembly 10.

In the present embodiment, the number of the purified water inlet portions 110 is not limited, and may be selected as needed. As a specific example, as shown in fig. 1 and 2, the number of the purified water inlet portions 110 is 4. In the present embodiment, the structure of the purified water inlet portion 110 is not limited, and may be selected as needed. As shown in fig. 1 and 2, the purified water inlet portion 110 includes a plurality of water inlets distributed in an array. It will be apparent that this is by way of example only and not by way of example only. In the present embodiment, the shape of the purified water inlet 110 is not limited, and may be selected as needed. As a specific embodiment, as shown in fig. 1 and 2, the water inlet portion 110 has a long shape, the water inlet portion 110 is disposed along the length direction of the water purifying pipe 100, and the length of the water inlet portion 110 is adapted to the length of the water purifying pipe 100. This results in a higher water output of the filter assembly 10.

The raw water pipe 200 is disposed along the length direction of the water purifying pipe 100, and is to be understood in a broad sense herein along the length direction. As a specific example, as shown in fig. 1 and 2, the raw water pipe 200 and the purified water pipe 100 are disposed in parallel, that is, the axis of the raw water pipe 200 and the axis of the purified water pipe 100 are parallel. It will be apparent that this is by way of example only and not by way of example only. For example, the raw water pipe 200 may be inclined with respect to the purified water pipe 100. The raw water pipe 200 is disposed along the length direction of the purified water pipe 100, which makes the water production efficiency of the filter assembly 10 high.

In the present embodiment, the structure of the raw water outlet 210 is not limited, and may be selected as needed. As shown in fig. 1 and 2, the raw water outlet 210 includes a plurality of water inlets distributed in an array. It will be apparent that this is by way of example only and not by way of example only. In the present embodiment, the shape of the raw water outlet portion 210 is not limited, and may be selected as needed. As a specific example, as shown in fig. 1 and 2, the raw water outlet 210 has a long shape, the raw water outlet 210 is disposed along the length direction of the raw water pipe 200, and the length of the raw water outlet 210 is adapted to the length of the raw water pipe 200. This results in a higher water output of the filter assembly 10 and a higher water production efficiency.

At least one raw water pipe 200 and at least one purified water inlet 110 are provided at intervals in the purified water pipe 100 along the circumferential direction of the purified water pipe 100. That is, as shown in fig. 1, 2 and 4, the raw water pipe 200 and the purified water inlet portion 110 are alternately arranged. Therefore, in the present embodiment, the number of raw water pipes 200 is not limited, and the number of raw water pipes 200 and the number of purified water inlet portions 110 are equal to satisfy that at least one raw water pipe 200 and at least one purified water inlet portion 110 are alternately arranged along the circumferential direction of the purified water pipe 100. In the present embodiment, the peripheral wall of the raw water pipe 200 has the raw water outlet portion 210, which makes the water production efficiency of the filter assembly 10 high, and the water flow rate in the raw water flow path 310 high.

In this embodiment, the specific components included in the membrane module are not limited and may be selected as desired. For example, the membrane assembly includes a membrane 330 folded in half, edges of the membrane 330 being sealed at opposite sides 331 thereof to form raw water flow paths 310 between the opposite sides 331 thereof. It is apparent that this is only exemplary and not exclusive, and that the membrane module may include a plurality of membranes 330, for example, the plurality of membranes 330 being bonded to form the raw water flow path 310. For example, the membrane module includes a raw water flow path 310 integrally formed. Therefore, the specific components included in the membrane module are not limited, and the membrane module may form the raw water flow passage 310.

In the present embodiment, the shape of the raw water flow path 310 is not limited, and may be selected as needed. As a specific example, the raw water flow path 310 has a bag shape.

As shown in fig. 1 and 2, the raw water pipe 200 is penetrated in the raw water flow passage 310, and it is apparent that this is only exemplary and not exclusive. At least the raw water outlet 210 of the raw water pipe 200 may be positioned in the raw water flow path 310 so that the raw water flow path 310 communicates with the corresponding raw water pipe 200.

Each of the raw water flow paths 310 is wound along the circumferential direction of the water purifying pipe 100, where the winding direction of each of the raw water flow paths 310 is uniform. As shown in fig. 1 and 2, each raw water flow path 310 is wound around the outer circumferential wall of the water purification pipe 100 in a clockwise or counterclockwise direction. The outside of the raw water flow path 310 may form a winding gap at the outside thereof during winding, and the winding gap is configured as the purified water flow path 320.

Since the purified water inlet 110 and the raw water pipe 200 are spaced apart, the membrane modules are disposed in one-to-one correspondence with the raw water pipe 200, and each raw water flow passage 310 is wound in the same direction. Accordingly, as shown in fig. 1 and 2, one purified water inlet portion 110 is provided in each of the purified water flow channels 320 such that each of the purified water flow channels 320 is respectively communicated with the purified water pipe 100.

The filter module 10 of the present utility model is configured to feed water into the raw water flow path 310 through the raw water outlet 210 provided on the peripheral wall of the raw water pipe 200, so that the flow rate in the raw water flow path 310 is high, and concentration polarization of the membrane module is avoided. The raw water flow path 310 starts from the raw water outlet 210 on the circumferential wall of the raw water pipe 200, and the process flow of the raw water flow path 310 is long and the water production efficiency is high.

In other embodiments, each membrane assembly includes a membrane 330. The membrane 330 is folded in half and its edges are sealed at opposite sides 331 thereof to form a raw water flow path 310 between the opposite sides 331 thereof, for providing the raw water pipe 200 corresponding thereto to the raw water flow path 310 and positioning the raw water outlet 210 in the raw water flow path 310 to communicate the raw water flow path 310 with the raw water pipe 200 corresponding thereto.

As shown in fig. 1 and 2, the membrane 330 is folded in half to form the raw water flow path 310 between opposite sides 331 of the membrane 330, and the purified water flow path 320 is formed at opposite sides 332 of the membrane 330. The opposite side 331 of the membrane 330 refers to the inside of the raw water flow path 310, and the opposite side 332 of the membrane 330 refers to the outside of the raw water flow path 310. This makes the manufacturing of the raw water flow path 310 relatively simple, and makes the raw water pipe 200 easy to detach and install.

In other embodiments, the doubled-up membrane 330 is wrapped around the clean water conduit 100 and forms the clean water flow path 320 between its opposite sides 332.

As shown in fig. 1 and 2, the membrane 330 is folded in half to form the raw water flow path 310 between opposite sides 331 of the membrane 330, and the purified water flow path 320 is formed at opposite sides 332 of the membrane 330. The opposite side 331 of the membrane 330 refers to the inside of the raw water flow path 310, and the opposite side 332 of the membrane 330 refers to the outside of the raw water flow path 310. The water purifying flow channel 320 is formed in a simple manner, and saves space.

In other embodiments, at least one recess 120 is provided on the outer peripheral wall of the water purifying pipe 100 at intervals along the circumferential direction thereof, and at least one raw water pipe 200 is fastened to the recess 120 in a one-to-one correspondence manner so that at least one raw water pipe 200 is provided on the water purifying pipe 100.

In the present embodiment, the number of the concave parts 120 is the same as the number of the raw water pipes 200. The recess 120 makes the assembly of the raw water pipe 200 relatively simple and firm.

In other embodiments, each raw water pipe 200 forms a raw water outlet 210 facing away from its corresponding recess 120 and communicates with the raw water flow passage 310 through the raw water outlet 210. As shown in fig. 1, 2 and 4, this makes the raw water outlet 210 face the raw water flow path 310, resulting in high water production efficiency of the filter assembly 10.

In other embodiments, the cross-section of each recess 120 is circular arc shaped. In the present embodiment, the circular arc shape does not mean a regular semicircular arc shape, and may be an elliptical arc or the like.

In other embodiments, the at least one raw water pipe 200 is adapted to the at least one recess 120 such that the cross-section of the at least one raw water pipe 200 after being assembled on the purified water pipe 100 is circular in shape. This allows the filter assembly 10 to be relatively symmetrical while allowing the cross-sections of the purified water flow path 320 and the raw water flow path 310 to be relatively uniform.

In other embodiments, at least one end surface of the water purification pipe 100 is provided with a purified water outlet 130. As a specific example, as shown in fig. 4, both end surfaces of the water purifying pipe 100 are provided with the purified water outlet 130, which makes the filter assembly 10 relatively easy to install, and saves space.

In other embodiments, at least one end surface of each raw water pipe 200 is provided with a raw water inlet 220. As a specific example, as shown in fig. 3, both end surfaces of the raw water pipe 200 are provided with raw water inlet portions 220. This makes the filter assembly 10 relatively easy to install and space saving.

In other embodiments, the winding end of the raw water flow path 310 is provided with a concentrated water outlet 311. As shown in fig. 3, the start of the raw water flow path 310 is a winding start. That is, the raw water flow path 310 starts from the raw water outlet 210 and ends at the outermost side of the membrane module. This results in a longer raw water flow path 310, a sufficient water production time, and a higher water production efficiency.
