Description

Technical Field

[0001] The utility model relates to a reverse osmosis device for removing highly concentrated brine, belonging to the field of reverse osmosis equipment. Background Art

[0002] Desalted water refers to water in which the strong electrolytes that are easy to remove are reduced or removed to a certain extent, wherein the salt content of desalted water is in the range of 1 to 5 mg / L. The main industrial method for preparing desalted water is electrodialysis, thereby taking advantage of the selective permeability of ion exchange membranes to ions and under the action of an external electric field, the cations and anions in the water are respectively concentrated to the two poles through the ion exchange membranes, so that the membrane area of ​​the permeable membrane becomes a fresh water area, and the outside of the membrane is a concentrated water area, and the water derived from the fresh water area is desalted water. In the prior art, when using a reverse osmosis device to prepare desalted water, it will enter the inside of the connecting pipe from the water inlet pipe, and the highly concentrated brine will be initially filtered through the metal mesh, and then transmitted through the reverse osmosis membrane for secondary filtration. However, the highly concentrated brine contains salt that contacts the metal mesh for a long time. The salt in the highly concentrated brine is easy to precipitate and solidify on the surface of the metal mesh, causing the filter mesh holes on the metal mesh to be blocked, thereby reducing the efficiency of the reverse osmosis device in preparing desalted water. Therefore, it is necessary to design a reverse osmosis device that can dredge the filter mesh holes on the metal mesh to remove highly concentrated brine. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a reverse osmosis device for removing highly concentrated brine to solve the problems raised in the above-mentioned background technology. The utility model can dredge the filter mesh on the metal mesh and improve the efficiency of the reverse osmosis device in producing desalted water.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a reverse osmosis device for removing highly concentrated salt water, comprising a reverse osmosis treatment tank, a supporting base is installed at the bottom of the reverse osmosis treatment tank, a protective sleeve is installed at the top of the reverse osmosis treatment tank, a water outlet pipe is installed inside the protective sleeve, the bottom of the water outlet pipe is connected and fixed to the reverse osmosis treatment tank, a round tube is installed inside the reverse osmosis treatment tank, a sleeve is installed inside the reverse osmosis treatment tank, the round tube is located inside the sleeve, a water outlet grid is opened on the round tube, and reverse osmosis membranes are installed on the inner wall and outer wall of the round tube. The bottom of the sleeve is inserted into the protective shell, the protective shell is installed on the reverse osmosis treatment tank, a metal mesh is installed in the reverse osmosis treatment tank, the metal mesh is located inside the protective shell, the metal mesh is located directly below the sleeve, a connecting pipe is installed at the bottom of the reverse osmosis treatment tank, a water inlet pipe is installed on one side of the connecting pipe, the connecting pipe is communicated with the inside of the metal mesh, a fixing plate is installed on the inner wall of the reverse osmosis treatment tank, an electric push rod is installed at the bottom of the fixing plate, the other end of the electric push rod is installed on the mounting plate, the mounting plate is installed on the fixing ring, and a cleaning piece is installed at the bottom of the fixing ring.

[0005] Furthermore, the diameter of the metal mesh is smaller than the inner diameter of the protective shell, the diameter of the round tube is smaller than the inner diameter of the sleeve, the water outlet pipe is connected to the round tube, and the other end of the sleeve is inserted into the protective shell.

[0006] Furthermore, mounting plates are installed on both sides of the fixing ring, the mounting plates are mounted on the guide rod, and the bottom of the guide rod is connected and fixed to the protective shell.

[0007] Furthermore, the cleaning member includes a positioning plate, which is installed at the bottom of the fixing ring. A movable groove is opened on one side of the positioning plate, a bottom plate is installed in the movable groove, a plurality of dredging heads are installed on the front side of the bottom plate, a spring is installed on the rear side of the bottom plate, the other end of the spring is installed in the telescopic groove, and the telescopic groove and the movable groove are connected.

[0008] Furthermore, limiting blocks are installed on both sides of the bottom plate, the limiting blocks are installed in limiting grooves, and the limiting grooves are arranged on the positioning plate.

[0009] Furthermore, an insert block is installed on one side of the mounting plate, the insert block is inserted in the fixing ring, a handle is installed on the top of the fixing ring, a round rod is installed on the bottom of the handle, a baffle is installed inside the fixing ring, a screw hole is opened on the baffle, and the round rod passes through the fixing ring and the insert block and is installed in the screw hole.

[0010] The beneficial effects of the utility model: the utility model is a reverse osmosis device for removing highly concentrated brine. When the reverse osmosis device starts to filter highly concentrated brine, the electric push rod will start to work to drive the fixed ring to move up and down, thereby driving the dredging head to rub in the filter mesh holes above the metal mesh to dredge the filter mesh holes. The mounting plate on the other side of the fixed ring is installed on the guide rod, which can limit the range of movement of the electric push rod when driving the fixed ring to rise and fall, so as to keep the fixed ring able to rise and fall smoothly.

[0011] There are multiple dredging heads evenly installed on the base plate. The top of the dredging heads is spherical and the back side of the base plate is inserted in the movable groove. The dredging heads can be driven to retract inward through the telescopic groove. When the electric push rod drives the positioning plate to move up and down to dredge the filter mesh holes on the metal mesh, when the dredging heads are aligned with the filter mesh holes, the spring pushes the base plate as a whole outward, so that the dredging heads are inserted into the filter mesh holes, pushing the solidified crystals into the filter mesh holes to clean the filter mesh holes.

[0012] Turning the handle drives the round rod to rotate, thereby separating the round rod from the baffle, and then separating the mounting block from the fixing ring, so as to facilitate replacement of the dredging head installed on the positioning plate when it is worn, thereby reducing the time spent on replacing the dredging head.
