Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membrane treatment equipment, in particular to a low-pressure reverse osmosis membrane treatment equipment with high efficiency and energy saving. Background Technique

[0002] The reverse osmosis membrane is an artificial semi-permeable membrane with certain characteristics made by simulating biological semi-permeable membranes. It is the core component of reverse osmosis technology. The principle of reverse osmosis technology is that under the action of a pressure higher than the osmotic pressure of the solution, other substances are separated from these substances and water based on the fact that other substances cannot pass through the semi-permeable membrane. The membrane pore diameter of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic substances, etc. in water.

[0003] When the existing reverse osmosis membrane treatment equipment is in use, it directly uses the reverse osmosis membrane for treatment. However, hardness ions in water, such as calcium and magnesium, will scale on the surface of the reverse osmosis membrane, thus shortening the service life of the reverse osmosis membrane. At the same time, large particle impurities and suspended substances in water will also increase the burden on the reverse osmosis membrane treatment equipment. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the above equipment is in use, due to the direct use of the reverse osmosis membrane in the existing reverse osmosis membrane treatment equipment, scaling will occur on the surface of the reverse osmosis membrane, shortening the service life, and to propose a low-pressure reverse osmosis membrane treatment equipment with high efficiency and energy saving.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a low-pressure reverse osmosis membrane treatment equipment with high efficiency and energy saving, including a bottom plate, four support columns are fixedly installed on the top of the bottom plate, a filter chamber is fixedly installed between the tops of the four support columns, a hole one is opened at the top of the filter chamber, a water inlet pipe is fixedly communicated with the inner wall of the hole one, four connecting rods are fixedly installed on the inner wall of the filter chamber, a water distribution plate is fixedly installed between the bottoms of the four connecting rods, a sand filter layer is arranged on the inner wall of the filter chamber, and filter water caps are arranged on the inner wall of the filter chamber.

[0011] Preferably, two second fixing rings are fixedly sleeved on the outer wall of the reverse osmosis membrane treatment pipe, and a group of fixing plates are fixedly installed on the outer wall of the support frame.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1-4 shown, the present invention provides an energy-efficient low-pressure reverse osmosis membrane treatment device, including a bottom plate 1, four support columns 2 are fixedly installed on the top of the bottom plate 1, a filter chamber 3 is fixedly installed between the tops of the four support columns 2, a hole 1 4 is opened at the top of the filter chamber 3, the inner wall of the hole 1 4 is fixedly communicated with a water inlet pipe 5, four connecting rods 6 are fixedly installed on the inner wall of the filter chamber 3, a water distribution tray 7 is fixedly installed between the bottoms of the four connecting rods 6, a sand filter layer 8 is arranged on the inner wall of the filter chamber 3, a filter water cap 9 is arranged on the inner wall of the filter chamber 3, a hole 2 10 is opened on the outer wall of the filter chamber 3, the inner wall of the hole 2 10 is fixedly communicated with a pipe 1 11, a valve 1 12 is arranged on the outer wall of the pipe 1 11, and the input end of the pipe 1 11 is fixedly communicated with a softener 13.

[0024] The overall effect achieved by the entire Embodiment 1 is that first, the water flow enters the filter chamber 3, and the water distribution tray 7 can make the water flow pass more evenly in the sand filter layer 8, so that the suspended substances and particulate matter in the water can be intercepted and removed more effectively. Secondly, it flows into the sand filter layer 8 again, which has a high filtration efficiency and treatment capacity, can reduce the load and operating cost of the subsequent treatment equipment. Finally, it passes through the filter water cap 9. The structure of the filter water cap 9 is reasonable, and the gap is not easy to deform, so that there is no dead water corner area between the filter plates, thereby effectively preventing the occurrence of mud accumulation phenomenon. This can not only improve the filtration effect, but also extend the service life of the reverse osmosis membrane treatment device.

[0025] Embodiment 2, as Figures 2-4As shown, a hole three 14 is provided on one side of the outer wall of the softener 13. A pipe two 15 is fixedly communicated with the inner wall of the hole three 14. A valve two 16 is arranged on the outer wall of the pipe two 15. The output end of the pipe two 15 is fixedly communicated with a reverse osmosis membrane treatment pipe 17. A pipe three 18 is fixedly communicated with one side of the outer wall of the reverse osmosis membrane treatment pipe 17. A valve three 19 is arranged on the outer wall of the pipe three 18. A controller 20 is fixedly installed on the top of the bottom plate 1. Two fixing rings one 21 are fixedly sleeved on the outer wall of the softener 13. A support frame 22 is fixedly installed on the outer wall of each of the two fixing rings one 21. Two fixing rings two 23 are fixedly sleeved on the outer wall of the reverse osmosis membrane treatment pipe 17. A group of fixing plates 24 are fixedly installed on the outer wall of the support frame 22.

[0026] The effect achieved by the entire Embodiment 2 is that when the device is in normal use, the operation of the softener 13 for water softening treatment can reduce the operation load of the reverse osmosis device, thereby reducing energy consumption, ensuring the stability of the water quality entering the reverse osmosis membrane, and reducing the impact on the system performance caused by water quality fluctuations. Secondly, the controller 20 controls the valve two 16 to make the water in the softener 13 enter the reverse osmosis membrane treatment pipe 17, which can further adapt to high-hardness water quality and improve the treatment effect. At the same time, the cooperation of the fixing ring two 23 with the support frame 22 and the fixing plate 24 can make the device operate more stably.

[0027] Among them, the softener 13, the reverse osmosis membrane treatment pipe 17 and the controller 20 are all prior arts, and their components and operating principles are all public technologies, and no more explanations will be made here.

[0028] Working principle: Firstly, when the device is in normal use, a water inlet pipe 5 is fixedly connected to the inner surface wall of the hole 4. Water can be put into the filter chamber 3 through the water inlet pipe 5. Secondly, four connecting rods 6 are fixedly installed on the inner surface wall of the filter chamber 3, and the four connecting rods 6 are fixedly connected to the water distribution plate 7. Due to the uniform distribution of the water distribution plate 7, the water flow can pass through the sand filter layer 8 more evenly, so that the suspended substances and particulate matters in the water can be intercepted and removed more effectively. This uniform filtering process can reduce the blockage and wear of the filter media, improve the filtering effect. Secondly, the sand filter layer 8 is arranged on the inner surface wall of the filter chamber 3. The water flow passes through the sand filter layer 8. The sand filter layer 8 has a large sewage interception capacity, can accommodate more pollutants, extend the filtering cycle, reduce the number of backwashes, and reduce the operation cost. The filter media particles in the sand filter layer 8 are uniform, which is beneficial to forming a stable filter layer and improving the filtering effect. At the same time, water filter caps 9 are arranged on the inner surface wall of the filter chamber 3. The design of the water filter caps 9 enables the water flow entering the filter chamber 3 to be evenly distributed, avoiding the problem of too large or too small local water flow, and helping to maintain the stability of the water flow in the filter chamber 3. Secondly, the filter chamber 3 is fixedly connected to the pipe 11. The water filtered once enters the softener 13 through the pipe 11. The softener 13 can ensure the stable water quality entering the reverse osmosis membrane treatment pipe 17, reduce the influence on the system performance due to water quality fluctuations, help to maintain the stable operation of the reverse osmosis equipment, reduce the failure rate and maintenance cost, help to maintain the stable operation of the reverse osmosis equipment, reduce the failure rate and maintenance cost. Secondly, entering the reverse osmosis membrane treatment pipe 17 through the pipe 15 can effectively remove impurities such as dissolved salts, colloids, organic matters, bacteria, and viruses in the water, and provide high-purity water. At the same time, the controller 20 is connected to the valve 12, the valve 16, and the valve 19, and can control the switch in real time. At the same time, the fixed ring 2 is connected to the support frame 22, which can make the device operate more stably.

[0029] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
