Description

Technical Field

[0001] This utility model relates to a filtration and impurity removal component for a superimposed concentration membrane device, belonging to the technical field of superimposed concentration membrane devices. Background Technology

[0002] Stacked membrane thickeners are a highly efficient membrane separation technology widely used in water treatment, wastewater reuse, food and beverage, and pharmaceutical industries. Their principle involves using multiple membrane modules stacked in series to separate water and other solutes in a solution, achieving concentration or purification. This equipment typically consists of multiple membrane modules arranged in a specific configuration, resulting in a large membrane area and high separation efficiency. By adjusting the pressure and flow rate of each membrane layer, the separation effect can be effectively improved while reducing energy consumption. Compared to traditional single-membrane systems, stacked membrane thickeners significantly increase processing capacity, save space, and are highly adaptable, capable of handling various types of liquids.

[0003] In existing technologies, ceramic membranes in superimposed concentration membrane equipment require regular cleaning and replacement by staff, which is time-consuming and labor-intensive. When impurities are present on the outer wall of the ceramic membrane, they can clog the membrane pores, leading to a decrease in membrane filtration efficiency and increasing the risk of membrane fouling. Long-term fouling accumulation can reduce membrane flux, affecting separation performance. If impurities deposited on the membrane surface are not cleaned promptly, they can accelerate the aging and corrosion of the membrane material, reducing the lifespan of the ceramic membrane. Long-term accumulation of impurities can also cause mechanical damage or chemical corrosion to the membrane surface, thereby affecting membrane stability.

[0004] Therefore, a filter and impurity removal component for a superimposed concentration membrane device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a filter and impurity removal component for a superimposed concentration membrane device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1-4As shown, this utility model embodiment provides a superimposed concentrator membrane equipment filtration and impurity removal component, including a concentrator tank 1. A maintenance cover plate 3 is provided on the front side of the concentrator tank 1. Multiple retaining seats 8 are provided at the bottom of the inner cavity of the concentrator tank 1. A ceramic membrane 7 is clamped to the top of the retaining seats 8. A cleaning component 6 is provided on the right side of the concentrator tank 1. The cleaning component 6 includes a transmission box 601, which is fixedly connected to the right side of the concentrator tank 1. Threaded rods 605 are movably connected to the upper and lower sides of the inner cavity of the transmission box 601 through bearings. Threaded sleeves 603 are threadedly connected to the surface of the threaded rods 605. A transmission rod 608 is fixedly connected to the right side of the threaded sleeves 603. A connecting plate 609 is welded to one end of the transmission rod 608. Multiple vertical rods 610 are fixedly connected to the bottom of the connecting plate 609. A scraper plate 611 is fixedly connected to one end of the vertical rods 610, and the scraper plate 611 is tightly fitted to the outer wall of the ceramic membrane 7. A servo motor 607 is provided at the top of the transmission box 601, and the output end of the servo motor 607 is fixedly connected to the threaded rod 605.

[0027] The output of the servo motor 607 drives the threaded rod 605 to rotate. The threaded rod 605 drives the threaded sleeve 603 to move upward through the thread. The threaded sleeve 603 drives the connecting plate 609 to move upward through the transmission rod 608. The connecting plate 609 drives the scraper plate 611 to move upward along the outer wall of the ceramic membrane 7 through the vertical rod 610, thereby cleaning the outer wall and preventing impurities from adhering and clogging the filter pores, which would reduce the membrane's filtration efficiency and increase the risk of membrane fouling, thus improving the separation efficiency.

[0028] Example 2

[0029] In one embodiment, a guide groove 606 is provided on the right side of the transmission box 601, and the right side of the transmission rod 608 passes through the guide groove 606 and extends to the outside of the transmission box 601. The outer wall of the transmission rod 608 is in contact with the guide groove 606. Multiple sealing rings 9 are provided on the top of the concentration tank 1, and the sealing rings 9 are in contact with the outer surface of the vertical rod 610. A water inlet 2 is provided on the left side of the bottom of the concentration tank 1, and a water outlet 5 is provided on the right side of the bottom of the concentration tank 1. A drain outlet 4 is connected to the middle of the bottom of the concentration tank 1, and a solenoid valve is provided at the bottom of the drain outlet 4. A sliding groove 604 is provided on the left side of the inner cavity of the transmission box 601, and a slider 602 is fixedly connected to the left side of the threaded sleeve 603. The slider 602 is slidably connected in the sliding groove 604.

[0030] By setting the sealing ring 9, the contact area between the vertical rod 610 and the concentration tank 1 can be made to fit, thereby improving the sealing effect. By setting the slider 602 and the sliding groove 604, the stability of the threaded sleeve 603 during movement can be improved. By setting the guide groove 606, the movement trajectory of the transmission rod 608 can be limited to prevent it from deviating during movement.

[0031] In operation, this invention connects both the inlet 2 and outlet 5 to corresponding external pipes, allowing liquid to enter the concentration tank 1 through the inlet 2. The liquid then passes through the ceramic membrane 7 and is discharged through the outlet 5, thus completing the filtration process. When impurity removal is required from the ceramic membrane 7, the output of the servo motor 607 drives the threaded rod 605 to rotate. The threaded rod 605, through its threads, moves the threaded sleeve 603 upwards. The threaded sleeve 603, via the transmission rod 608, moves the connecting plate 609 upwards. The connecting plate 609, via the vertical rod 610, moves the scraper 611 upwards along the outer wall of the ceramic membrane 7, cleaning its outer wall and preventing impurities from clogging the filter pores, thus reducing the membrane's filtration efficiency, increasing the risk of membrane fouling, and ultimately improving separation efficiency.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
