Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment devices, and in particular relates to a reverse osmosis treatment device. Background Technology

[0002] Reverse osmosis (RO) devices use high pressure to force water through a semi-permeable membrane, causing the solvent (usually water) to diffuse from the side of high concentration to the side of low concentration, thus achieving separation, purification, and concentration. In this process, salts and other impurities are retained on one side of the membrane, while pure water passes through to the other side. However, it still has the following drawbacks in practical use:

[0003] In a reverse osmosis treatment unit, raw water is pressurized by a high-pressure pump and enters the membrane module. Under the action of transmembrane pressure difference, solute separation is achieved through a semi-permeable membrane. Traditional membrane modules are limited by structural design, and the effective membrane area is usually low, which leads to limited water production per unit time and affects the overall energy efficiency of the system.

[0004] Secondly, in the reverse osmosis process of water treatment, the semipermeable membrane, as a key filtration medium, is in a high-pressure working environment for a long time. As the treatment process progresses, the solute concentration on the feed water side continues to increase, and the osmotic pressure increases accordingly. At this time, the system needs to increase the operating pressure to maintain the permeate flux. However, if the operating pressure exceeds the mechanical strength limit of the semipermeable membrane, it may cause irreversible expansion and deformation of the membrane material, or even cause the membrane to rupture, thereby affecting the desalination performance of the system and shortening the service life of the membrane. Utility Model Content

[0005] The purpose of this invention is to provide a reverse osmosis treatment device. By setting up a fixed box, osmosis components and mounting bracket, it solves the problems of limited effective membrane treatment area, insufficient treatment efficiency and easy deformation and rupture of the membrane under pressure during production.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a reverse osmosis treatment device, comprising a fixed box, a osmosis component, and a mounting frame. The top of the fixed box is open, and an inner frame is fixed to the upper part of the fixed box. The osmosis component is movably connected within the inner frame. The osmosis component includes a support frame, a semi-permeable membrane, and protective rods. The support frame is located at the top of the inner frame, and several equally spaced semi-permeable membranes are fixed within the support frame. Equally spaced protective rods are fixed to both sides of the semi-permeable membranes. A mounting frame is fixed to the upper edge of the outer side of the fixed box, and a mounting bracket is fixed to the top of the mounting frame. A water delivery chamber is fixedly connected to the center of the top of the mounting bracket, and an output pipe is fixedly connected to one end of the water delivery chamber. During operation, the osmosis component is housed within the fixed box. After the mounting bracket is installed on top of the fixed box, it closes the top of the fixed box. Water is delivered to the mounting bracket and then to the osmosis component inside the fixed box, where it is filtered to remove ions.

[0008] Furthermore, a T-pipe is fixedly connected to the lower part of one end of the fixed box, and several parallel support bars are fixed inside the lower part of the fixed box, with the length direction of the support bars being parallel to the length direction of the fixed box. The T-pipe on the fixed box inputs flushing water and outputs treated water, and the support bars in the fixed box provide support for the support plate.

[0009] Furthermore, the permeation assembly also includes a sealing ring and a fixing plate. Sealing rings are fixed at the top and bottom of the support frame. The sealing ring at the top of the support frame abuts against the mounting bracket, and the sealing ring at the bottom of the support frame abuts against the inner frame. A fixing plate is fixed between two adjacent semipermeable membranes. The fixing plate is fixed inside the support frame. The gap between the fixing box and the mounting bracket is sealed on the permeation assembly by the sealing ring.

[0010] Furthermore, the tops of the protective rods on the two semi-permeable membranes near the two ends of the fixed box, which are far apart from each other, are fixed to the bottom of the support frame, and the protective rods on the sides of the two adjacent semi-permeable membranes are fixed to the bottom of the fixed plate to protect the semi-permeable membranes.

[0011] Furthermore, the permeation assembly also includes a support plate, with a support plate fixed to the bottom of each semipermeable membrane, and protective rods on both sides of each semipermeable membrane fixed to the top of the support plate at the bottom of the semipermeable membrane. The bottom of the support plate is supported on the top of the support bar, and the semipermeable membrane supports the support bar through the support plate.

[0012] Furthermore, both ends of the three-way pipe away from the fixed box are fixedly connected to an electric control valve, the output pipe is fixedly connected to an electric control valve, and the top center of the water supply tank is fixedly connected to an inlet pipe. When the three-way pipe is working, the electric control valve controls the flow of the three-way pipe, and the output pipe is controlled by the electric control valve.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problems of limited effective membrane treatment area and insufficient treatment efficiency in reverse osmosis treatment devices by setting up a fixed box and permeation components. The high-ion-concentration water to be treated is transported from the water supply tank to the fixed box, and then to a semi-permeable membrane fixed in the support frame. The semi-permeable membrane forms a square frame structure that is open from top to bottom, and the bottom is closed by a fixed support plate. After entering the semi-permeable membrane, the water containing ions is permeated into the fixed box. The vertical arrangement of multiple semi-permeable membranes increases the water treatment efficiency. After entering the lower part of the fixed box, the treated water is transported to a three-way pipe and output through the end of the three-way pipe connected to the outlet pipe for treated water. This increases the permeation treatment area and improves the permeation treatment efficiency during operation.

[0015] This invention solves the problem of membrane deformation and rupture under pressure during the production of reverse osmosis treatment devices by setting up a fixed box, permeation components, and mounting brackets. The water to be treated is first transported to the water supply tank through the inlet pipe, and then to the fixed box. After passing through the semi-permeable membrane and being filtered, the water is then transported back to the fixed box, and from there to a three-way pipe, which in turn transports it to the treated water delivery equipment. After the water enters the semi-permeable membrane, the support plate at the bottom of the membrane rests on the support bars inside the fixed box, providing support for the bottom of the membrane. The tops of the protective rods on both sides of the semi-permeable membrane are fixed to the fixed plate or support frame, and the bottoms are fixed to the support plate, protecting the membrane and preventing it from rupturing under water pressure. This significantly increases the support strength of the semi-permeable membrane during the production of the reverse osmosis treatment device and reduces the risk of membrane rupture due to pressure.

The permeation component 2 is installed in the fixed box 1, and the inner frame 104 movably connects the permeation component 2 to the fixed box 1. The permeation component 2 is movably connected inside the inner frame 104. When the water to be treated passes through the fixed box 1, it is permeated by the permeation component 2 to remove ions. The permeation component 2 includes a support frame 201, a semi-permeable membrane 204, and protective rods 205. The support frame 201 is located on the top of the inner frame 104.

The support frame 201 supports the semi-permeable membranes 204 on the inner frame 104 inside the fixed box 1. The support frame 201 fixes the semi-permeable membrane 204 within it. The protective rod 205 on the surface of the semi-permeable membrane 204 provides certain support during the osmosis process to prevent the semi-permeable membrane 204 from being burst by water pressure during operation. An installation frame 103 is fixed at the upper edge of the outer side of the fixed box 1. The installation frame 103 fixes the installation bracket 3 on it. The installation bracket 3 is fixed at the top of the installation frame 103. The installation bracket 3 and the installation frame 103 are installed together by installation bolts and installation nuts. A water supply tank 301 is fixedly connected to the top center of the installation bracket 3. During operation, the water supply tank 301 delivers the water that needs to be osmotically treated to the osmosis component 2 inside the fixed box 1. One end of the water supply tank 301 is fixedly connected to an output pipe 303. The output pipe 303 is used to output the high-ion-concentration water that remains in the water supply tank 301 and the osmosis component 2 after a certain period of osmosis treatment.

[0027] Specifically, a three-way pipe 101 is fixedly connected to the lower part of one end of the fixed box 1.

[0030] The operation process of this embodiment is as follows: During operation, the water to be treated is transported from the water supply tank 301 to the fixed box 1, and then to the semi-permeable membrane 204 fixed in the support frame 201.

After entering the lower part of the fixed box 1, the treated water is transported to the three-way pipe 101 and output through the end of the three-way pipe 101 connected to the pipeline for outputting the treated water. This increases the area of ​​permeation treatment and the efficiency of permeation treatment during operation. Specific Implementation Example 2

After passing through the semi-permeable membrane 204, the water is filtered by the semi-permeable membrane 204 and then transported to the fixed tank 1. In the fixed tank 1, it is transported to the three-way pipe 101, and then to the water delivery equipment after treatment. After the water enters the semi-permeable membrane 204, the support plate 206 at the bottom of the semi-permeable membrane 204 is supported on the support strip 102 in the fixed tank 1, providing support for the bottom end of the semi-permeable membrane 204.

Every hour or so, the solenoid valve 304 on the tee pipe 101 near the treated water pipeline is closed, and another solenoid valve 304 connected to the end of the flushing water pipeline is opened. The flushing water is delivered to the fixed tank 1 through the tee valve.
