DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0022] For ease of description, spatially relative terms such as "above," "above," "on the upper surface of," and "upper" may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in a drawing is inverted, a device described as "above" or "on top of" another device or structure would then be positioned as "below" or "below" the other device or structure. Thus, the exemplary term "above" can include both the "above" and "below" orientations. The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.

[0024] The reverse osmosis membrane 7 is a columnar structure. A liquid inlet 71 is provided at one end of the columnar structure. A refined water outlet 73 is provided at the other end of the columnar structure through a refined water core column 74 located in the center. A raw water outlet 72 is provided around refined water outlet 73. A membrane housing 75 is located outside the columnar structure. A membrane 77 is positioned along the columnar structure between the membrane housing 75 and the refined water core column 74. A screen 76 is provided between the membrane 77 and the membrane housing 75. A separator 78 is provided between the membrane 77 and the refined water core column 74. Seals 79 are provided at both ends of the membrane housing 75. Two or more reverse osmosis membranes 7 are installed within the upper housing 8. Six reverse osmosis membranes 7 are installed within the upper housing 8.

[0025] A water inlet 2 is opened on the side of the lower shell 1, the motor 3 of the centrifugal pump is placed in the lower shell 1, and the pump body 4 of the centrifugal pump is installed on the upper part of the motor 3. The pump body 4 is driven by the motor 3 to rotate to pump water, and a water outlet pipe 5 is installed above the pump body 4. Above the water outlet pipe 5 is a head 6 at the upper part of the mouth of the entire centrifugal pump. A reverse osmosis membrane 7 is arranged around the water outlet pipe 5 at the lower part of the head 6, wherein the reverse osmosis membrane 7 is a tubular structure, the upper part of which is a liquid inlet 71, and the middle of the upper part is a closed structure. The liquid inlet 71 is arranged around the upper part of the reverse osmosis membrane 7, the lower middle part of the tubular structure of the reverse osmosis membrane 7 is a fine filtered water outlet 73, and the surrounding part is a raw water outlet 72. The fine filtered water core column 74 is arranged in the middle of the reverse osmosis membrane 7, and the outermost side of the reverse osmosis membrane 7 is a membrane shell 75. At the outermost side of the reverse osmosis membrane 7 is the upper shell 8 of the centrifugal pump. A fine water chamber 9 and a raw water chamber 11 are provided between the upper shell 8 and the lower shell 1. The water flowing out of the fine water chamber 9 flows out through the fine water outlet 10 on its side wall, and the water flowing out of the raw water chamber 11 flows out through the raw water outlet 12 on its side wall.

[0026] The water to be pumped and filtered enters through the water inlet 2 at the bottom of the centrifugal pump. The motor 3 provides power to drive the pump body 4 to rotate, raising the water and pumping it upward through the outlet pipe 5. When the water reaches the head 6, the water passing through the head 6 flows downward and around and enters the liquid inlet 71 at the top of the reverse osmosis membrane 7. The water flow rate decreases through the liquid inlet 71, generating pressure. Under the action of pressure, the water flows through the screen 76, membrane 77, and isolation net 78 and then enters the fine filtration water core column 74, and flows out from the fine filtration water outlet 73. The water that has not passed through the membrane flows out from the raw water outlet 72 around the lower part of the reverse osmosis membrane 7. The filtered water flowing out of the central filtered water outlet 73 is connected to the filtered water chamber 9 via a pipeline provided at the bottom. The filtered water chamber 9 is an annular structure surrounding the pump body 4. The upper portion of the filtered water chamber 9 is equipped with a corresponding interface for each filtered water outlet 73 below the reverse osmosis membrane 7. The filtered water is collected in the filtered water chamber 9 and flows out through the filtered water outlet 10. Raw water that has not passed the filtration enters the liquid inlet 71 at the upper portion of the reverse osmosis membrane 7 and flows directly out of the raw water outlet 72. The outflowing raw water flows into the raw water chamber 11, where it is collected and then flows out of the raw water outlet 12.

[0027] In some embodiments, the raw water chamber 11 is positioned above the polished water chamber 9. Raw water flowing out of the raw water outlet 72 enters the raw water chamber 11 below the reverse osmosis membrane 7 directly, and then flows out of the raw water outlet 12. For the polished water flowing out of the polished water outlet 73, a pipeline is installed below the polished water outlet 73. The pipeline passes through the raw water chamber 11 and enters the polished water chamber 9 below. The water is then collected within the polished water chamber 9 and flows out of the polished water outlet 10. In other embodiments, the polished water chamber 9 is positioned above the raw water chamber 11. The polished water flowing out of the polished water outlet 73 enters the polished water chamber 9 below the reverse osmosis membrane 7 directly, while a pipeline is installed at the raw water outlet 72, passing through the polished water chamber 9 and entering the raw water chamber 11 below for collection.

[0028] In some embodiments, the liquid inlet 71 is arranged around the upper part of the reverse osmosis membrane 7, and the direction of water filtration is from the surrounding areas to the middle, while in other embodiments, the liquid inlet 71 can also be arranged in the middle of the reverse osmosis membrane 7, and the direction of water filtration is from the middle to the surrounding areas. Of course, in this case, the raw water outlet 72 is arranged in the middle position of the lower part of the reverse osmosis membrane 7, and the refined water outlet 73 is arranged at the peripheral position of the lower part of the reverse osmosis membrane 7, and at this time, the raw water chamber 11 is arranged in the lower part of the refined water chamber 9, that is, a pipeline passing through the refined water chamber 9 is arranged at the raw water outlet 72, which makes the structural design of the pump more reasonable.

[0029] The fine filtered water outlet 10 and the raw water outlet 12 are set on the side wall of the centrifugal pump. The location of the setting can be selected according to the usage scenario. The direction of the fine filtered water outlet 10 and the raw water outlet 12 can be set to the same direction, that is, water is discharged from one side of the centrifugal pump ( Figure 5 ), of course, the directions of the two can also be set to opposite directions, that is, water is discharged from both sides of the centrifugal pump ( Figure 6 ), of course, the two can be set to certain other angles according to different needs.

[0030] According to the size and water treatment capacity of the centrifugal pump and the size of the reverse osmosis membrane 7 itself, different numbers of reverse osmosis membranes 7 can be selectively installed, and the water pressure is also a factor that needs to be considered, that is, the water pumping volume of the motor 3 must match the processing volume of the reverse osmosis membrane 7, especially the water pumping volume of the motor 3 must be greater than or equal to the processing volume of all reverse osmosis membranes 7, so that a pressure difference will be generated, and the water will have the power to pass through the reverse osmosis membrane 7 under the action of the pressure difference. Of course, the water output can also be controlled by setting the coarseness of the fine filtered water outlet 10 and the raw water outlet 12 to control the water pressure for filtration.
