Description

Technical Field

[0001] This utility model relates to the technical field of reverse osmosis purified water units, and in particular to reverse osmosis purified water units for use in production workshops. Background Technology

[0002] In production workshops, purified water is an indispensable key element in many process steps. Reverse osmosis purified water units are a type of equipment that uses reverse osmosis technology to produce high-purity water, and are widely used due to their efficient water purification capabilities.

[0003] Currently, when reverse osmosis water purification units are in use, the water source often contains a large amount of mineral ions such as calcium and magnesium, as well as various suspended particles. When these substances come into contact with the reverse osmosis membrane, they will gradually deposit on the surface of the reverse osmosis membrane, which easily leads to scaling. Scaled reverse osmosis membranes not only significantly reduce water treatment efficiency, but also greatly shorten their service life, thereby increasing equipment maintenance costs and replacement frequency. Therefore, to solve this problem, designing reverse osmosis water purification units for production workshops is something we need to consider. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a reverse osmosis purified water unit for production workshops. This unit incorporates a pretreatment mechanism to pre-filter water before it enters multiple reverse osmosis membrane modules, thereby preventing scaling on the reverse osmosis membranes and ensuring their long-term use. It also allows for convenient maintenance of the rectangular hollow block and its internal components, ensuring the filtration effect of the pretreatment mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reverse osmosis purified water unit for production workshops includes a frame with a support platform fixedly connected to it. Multiple reverse osmosis membrane modules are installed on the upper end of the support platform. A pretreatment mechanism includes a housing fixedly connected to the frame. U-shaped limiting blocks are fixedly connected to the top and bottom of the housing. A rectangular hollow block is positioned between two U-shaped limiting blocks. Multiple infusion holes are provided on both the left and right sides of the rectangular hollow block. A PP cotton filter element, a softening resin layer, and activated carbon are sequentially arranged inside the rectangular hollow block from right to left. A sealing door is rotatably installed on the front side of the housing.

[0007] Preferably, a first sealing gasket is fixedly connected to the inner side of each of the two U-shaped limiting blocks, and the upper and lower ends of the rectangular hollow block are respectively attached to the corresponding first sealing gasket.

[0008] Preferably, a second sealing gasket is fixedly connected to the rear inner wall of the housing, and the rear side of the rectangular hollow block is in contact with the second sealing gasket.

[0009] Preferably, a third sealing gasket is fixedly connected to the rear side of the sealing door, and the front side of the rectangular hollow block is in contact with the third sealing gasket.

[0010] Preferably, the right side of the housing is connected to an inlet pipe, the left side of the housing is connected to an outlet pipe, and the other end of the outlet pipe is connected to the inlet pipe of multiple reverse osmosis membrane modules through a four-way fitting.

[0011] Preferably, a controller is mounted on the rack.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] A pretreatment mechanism is installed, which controls the water source to pass sequentially through the PP cotton filter element, softening resin layer and activated carbon inside the rectangular hollow block. Before the water source enters the reverse osmosis membrane module, it can effectively filter large particulate impurities, calcium and magnesium ions and micro particles in the water source, thereby effectively avoiding the occurrence of reverse osmosis membrane scaling, reducing the filtration burden of the reverse osmosis membrane and ensuring its effective long-term use. At the same time, the rectangular hollow block and its internal components can be easily replaced and maintained by opening the sealed door, which effectively ensures the pretreatment effect of the pretreatment mechanism on the water source.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 The reverse osmosis purified water unit used in the production workshop includes a frame 1, a support platform 2 fixedly connected to the frame 1, and multiple reverse osmosis membrane modules 3 installed on the upper end of the support platform 2. This is existing technology, mainly composed of reverse osmosis membranes and pressure-resistant shells that house the membrane elements, which can effectively remove dissolved salts, microorganisms, organic matter and other impurities from the water source.

[0021] The system also includes a pretreatment mechanism, which comprises a housing 4 fixedly connected to the frame 1. A liquid inlet pipe 15 is connected to the right side of the housing 4, allowing the water to be filtered to flow into the entire device. A liquid delivery pipe 16 is connected to the left side of the housing 4, with the other end of the delivery pipe 16 connected to the inlet pipes of multiple reverse osmosis membrane modules 3 via a four-way fitting 17. U-shaped limiting blocks 5 are fixedly connected to the inner top and bottom of the housing 4. A rectangular hollow block 6 is positioned between two U-shaped limiting blocks 5. The two U-shaped limiting blocks 5, together with the sealing door 11, ensure stable positioning of the rectangular hollow block 6. Multiple liquid delivery holes 7 are provided on both the left and right sides of the rectangular hollow block 6. This ensures the normal flow of water. The rectangular hollow block 6 contains, from right to left, a PP cotton filter element 8, a softening resin layer 9, and activated carbon 10. The PP cotton filter element 8 can filter large particles such as mud and suspended solids in the water source. The softening resin layer 9 can remove calcium and magnesium ions in the water source through ion exchange, thereby preventing the reverse osmosis membrane from scaling rapidly and affecting its normal use. The activated carbon 10 can further adsorb small particles in the water source, thereby improving the taste of the water and reducing the burden on the reverse osmosis membrane. A sealing door 11 is rotatably installed on the front side of the shell 4. By opening the sealing door 11, the rectangular hollow block 6 and its internal components can be maintained and replaced.

[0022] The inner sides of the two U-shaped limiting blocks 5 are fixedly connected with first sealing gaskets 12. The upper and lower ends of the rectangular hollow block 6 are respectively attached to the corresponding first sealing gaskets 12. The inner rear wall of the housing 4 is fixedly connected with a second sealing gasket 13. The rear side of the rectangular hollow block 6 is attached to the second sealing gasket 13. The rear side of the sealing door 11 is fixedly connected with a third sealing gasket 14. The front side of the rectangular hollow block 6 is attached to the third sealing gasket 14. Through the cooperation of the first sealing gasket 12, the second sealing gasket 13 and the third sealing gasket 14, it can be ensured that the water source can stably pass through the rectangular hollow block 6 for pretreatment before entering the multiple reverse osmosis membrane modules 3.

[0023] In this invention, during use, the water to be filtered is first transported into the housing 4 of the pretreatment mechanism through the inlet pipe 15. After entering the housing 4, the water passes through multiple inlet holes 7 on both sides of the rectangular hollow block 6, passing through the interior of the rectangular hollow block 6. During this process, the water passes from right to left through the PP cotton filter element 8, the softening resin layer 9, and the activated carbon 10. The PP cotton filter element 8 can filter large particulate impurities such as silt and suspended solids in the water, while the softening resin layer 9 can remove calcium and magnesium from the water through ion exchange. Ions prevent rapid scaling of the reverse osmosis membrane in the reverse osmosis membrane module 3, ensuring the normal use of the reverse osmosis membrane. Activated carbon 10 can further adsorb tiny particles in the water source, improve the taste of the water and reduce the burden on the reverse osmosis membrane. Then, the pretreated water source will be transported to the corresponding reverse osmosis membrane module 3 through the inlet pipe 16, the four-way fitting 17 and the inlet pipes of multiple reverse osmosis membrane modules 3. The reverse osmosis membrane module 3 can effectively remove impurities such as dissolved salts, microorganisms and organic matter in the water source, and finally obtain purified water.

[0024] It is worth mentioning that when maintenance or replacement of the rectangular hollow block 6 and its internal components is required, the rectangular hollow block 6 can be easily pulled out from the housing 4 and maintained by opening the sealing door 11 to ensure the effectiveness of subsequent water pretreatment. After maintenance, the new rectangular hollow block 6 is inserted between the two U-shaped limit blocks 5 and the sealing door 11 is closed. Through the cooperation of the two first sealing gaskets 12, the second sealing gasket 13 and the third sealing gasket 14, the sealing between the rectangular hollow block 6 and the housing 4 can be ensured, ensuring that the water source can stably pass through the rectangular hollow block 6 for pretreatment and preventing the water source from flowing out directly without pretreatment.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
