Technical Field
[0001] This utility model belongs to the technical field of membrane separation devices, specifically relating to a water-saving and energy-saving membrane separation device. Background Technology
[0002] In today's world, where resources are increasingly scarce, water and energy conservation have become crucial directions for development across various industries. Traditional separation technologies are energy and water-intensive, making it difficult to meet the demands of sustainable development. Membrane separation technology has gradually emerged as a highly efficient separation method, but early devices suffered from high energy consumption and poor water-saving performance. To address these pain points, water- and energy-saving membrane separation devices have been developed. These devices integrate advanced materials and processes, aiming to achieve highly efficient material separation with lower energy and water consumption, bringing new breakthroughs to industrial production and resource utilization.
[0003] In existing membrane separation devices, the degree of impurity accumulation varies at different locations on the filter membrane during long-term use. Excessive impurities in certain areas can lead to localized clogging of the filter membrane, affecting the overall filtration efficiency. Furthermore, the existing rinsing process lacks a structure to specifically rinse each location, failing to remove impurities accumulated at different levels in different areas, thus causing localized clogging and reducing filtration efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a water-saving and energy-efficient membrane separation device to solve the problem in the background art where the degree of impurity accumulation in different locations of the filter membrane varies during long-term use, and excessive local impurities can lead to localized clogging of the filter membrane, affecting the overall filtration effect. Furthermore, existing rinsing processes lack a structure for targeted rinsing of different locations, failing to remove impurities of varying degrees accumulated in different areas, thus causing localized clogging problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-saving and energy-saving membrane separation device, comprising a separation tank and a filter membrane disposed in the middle of the separation tank for filtration;
[0006] Fixing frames are provided on the upper and lower sides of the filter membrane and at the connection position of the separation tank;

[0015] Compared with the prior art, this utility model provides a water-saving and energy-saving membrane separation device, which has the following beneficial effects:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides, for example Figure 1-6 The water-saving and energy-saving membrane separation device shown includes a separation tank 1 and a filter membrane 7 disposed in the middle of the separation tank 1 for filtration.
[0027] Fixing frames 8 are provided on the upper and lower sides of the filter membrane 7 and at the connection position of the separation tank 1;
[0028] A water inlet valve 2 is installed on the upper left side of the separator tank 1, and a water outlet valve 3 is installed on the lower right side of the separator tank 1.
[0029] A drive motor 6 connected to an external power supply is installed on the upper right side of the separation tank 1. A threaded rod 11 is connected to the lower side of the drive motor 6. A slider 12 is installed on the lower outer side of the threaded rod 11. A nozzle 13 is installed on the left side of the slider 12.
[0030] A flushing valve 4 is installed at the lower side of the inlet valve 2, and a discharge valve 5 is installed at the upper side of the outlet valve 3. A flushing pipe 9 is installed through the middle of the right side of the flushing valve 4.
[0031] In this embodiment, the device is based on the principle of membrane separation technology. It utilizes the selective permeability of the filter membrane 7 to separate substances from the water entering the separation tank 1. During normal operation, the inlet valve 2 is opened, and the water flows into the separation tank 1 from the upper left side. As the water flows naturally inside the separation tank 1, it encounters the filter membrane 7 located in the middle of the tank. Based on its own characteristics, the filter membrane 7 allows certain substances (such as solvents and small molecules) to pass through while blocking other substances (such as large molecular impurities and particles), thereby achieving water filtration and purification. The water filtered by the filter membrane 7 flows out from the outlet valve 3 on the lower right side of the separation tank 1, completing the water purification and separation process. This process continues continuously, achieving a stable filtration output.
[0032] As the filtration process continues, impurities gradually accumulate on the surface of the filter membrane 7, affecting its filtration performance and efficiency. Therefore, regular rinsing is required. The rinsing process is based on the principle of high-pressure water flushing, which thoroughly and efficiently washes the surface of the filter membrane 7 to remove the attached impurities and restore the performance of the filter membrane 7.
[0033] like Figure 1-6 As shown, the flushing pipe 9 is connected to the nozzle 13. The nozzle 13 is connected to the slider 12 by bolts. The slider 12 is connected to the threaded rod 11 by threads. The slider 12 is also connected to the separation tank 1 by snap-fit connection. The lower end of the threaded rod 11 is fitted into the separation tank 1. A sealing ring 10 is provided at the connection between the threaded rod 11 and the upper end of the separation tank 1. The flushing pipe 9 can be connected to an external high-pressure water supply device. The flushing pipe 9 is specifically a corrugated pipe. The flushing valve 4, the discharge valve 5, the inlet valve 2, and the outlet valve 3 are respectively provided with covers for sealing the separation tank 1. The upper end of the flushing pipe 9 can be connected to the cover on the outside of the flushing valve 4 by threads.
[0034] Preferably, when it is confirmed that the filter membrane 7 needs to be rinsed, the user first closes the inlet valve 2 and the outlet valve 3 to prevent the water to be treated from entering and the filtered water from flowing out of the separator tank 1, creating a relatively independent environment for the rinsing work. At the same time, the rinsing valve 4 and the discharge valve 5 are opened to allow the rinsing water to smoothly enter the separator tank 1 and the wastewater generated during rinsing to be discharged in a timely manner.
[0035] The user starts the drive motor 6, which then begins to work, converting electrical energy into mechanical energy and outputting rotational power.
[0036] The rotation of the drive motor 6 is transmitted to the threaded rod 11, which is connected to it, causing the threaded rod 11 to rotate around its own axis. Since the slider 12 is threadedly connected to the threaded rod 11 and is connected to the inner wall of the separation tank 1 via a snap-fit connection, the slider 12 is restricted to linear up-and-down movement along the inner wall of the separation tank 1. As the threaded rod 11 rotates, according to the principle of threaded transmission, the slider 12 moves up and down along the axial direction of the threaded rod 11, following its rotation.
[0037] The nozzle 13 connected to the left side of slider 12 moves synchronously with slider 12. An external high-pressure water supply device delivers high-pressure water to nozzle 13 through flushing pipe 9. As nozzle 13 moves, it sprays high-pressure water evenly onto the surface of filter membrane 7. Due to the movement of nozzle 13, different areas of filter membrane 7 are covered, thus thoroughly flushing all areas of filter membrane 7 and removing impurities accumulated to varying degrees.
[0038] Wastewater generated during the rinsing process is discharged from the separation tank 1 through the opened discharge valve 5, completing the entire rinsing process.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
