Description

Technical Field

[0001] This utility model belongs to the field of wastewater filtration membrane production technology, and specifically relates to a filtration performance testing device for wastewater filtration membrane production. Background Technology

[0002] With the development of society and economy and the improvement of people's environmental awareness, sewage treatment has become the top priority of environmental protection work now and in the future. Membrane separation technology is the fastest developing and most widely used technology in the past 40 years. The basic principle of membrane technology in water treatment is to use the ability of water molecules in the aqueous solution to pass through the sewage filtration membrane, while solutes or other impurities cannot pass through the sewage filtration membrane. Under the action of external force, the aqueous solution is separated to obtain pure water, thereby achieving the purpose of improving water quality.

[0003] Chinese patent CN202220535973.5 discloses a filter material filtration performance testing device, including a testing water tank, a support plate fixedly connected to the rear end of the upper surface of the testing water tank, and a fixed top plate fixedly connected to the upper rear side of the support plate.

[0004] Existing membrane performance testing methods typically test the entire wastewater filtration membrane, failing to specifically test the filtration performance of a particular point on the membrane. This results in a lack of comprehensive and rigorous testing of membrane performance, ultimately affecting the accuracy of the test results.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in related technologies, this utility model proposes a filtration performance testing device for wastewater filtration membrane production, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a filtration performance testing device for wastewater filtration membrane production, comprising a housing. Inside the housing are a limiting component and an auxiliary component. The limiting component limits the position of the wastewater filtration membrane, and the auxiliary component allows for horizontal translation to adjust the position of the membrane for wastewater detection. Support plates are connected to the inner walls on both sides of the housing, and wastewater filter screens are placed on the tops of the two support plates. A drive source is connected to one side of the housing, and the power output of the drive source is connected to the auxiliary component. A protective cover is connected to the top of the housing, and a water quality analyzer is connected to the inside of the protective cover.

[0009] Furthermore, the limiting assembly includes two fixed plates, two connecting plates, four sealing gaskets, and four outward expansion springs. The two fixed plates are symmetrically arranged on the inner walls of both sides of the housing. The bottom ends of the two fixed plates are connected to two sliding rods. The inner side of each connecting plate is slidably connected to the outer side of each pair of sliding rods. The bottom ends of the two connecting plates are connected to two connecting shells. The inner sides of the four connecting shells are rotatably connected to limiting rollers. The four sealing gaskets are respectively disposed on the surface of the four limiting rollers. The four outward expansion springs are respectively sleeved on the outer side of the four sliding rods.

[0010] Furthermore, one side of each of the two connecting plates is fitted against the inner wall of the housing.

[0011] Furthermore, the two ends of each pair of the outwardly expanding springs are respectively connected to the bottom end of each of the fixed plates and the top end of each of the connecting plates.

[0012] Furthermore, the auxiliary components include a reciprocating lead screw, a connecting frame, and a water guide bucket. The reciprocating lead screw is disposed on the power output end of the drive source. An adjusting plate is slidably connected to the surface of the reciprocating lead screw. The top end of the adjusting plate is in contact with the inner side of the top end of the housing. The connecting frame is disposed at the bottom end of the adjusting plate. A water inlet pipe is connected to one side of the connecting frame. The surface of the water inlet pipe is connected to the interior of the other side of the housing. The water guide bucket is disposed on the inner side of the housing. A water outlet pipe is connected to the bottom end of the water guide bucket. The surface of the water outlet pipe is connected to the interior of one side of the housing.

[0013] Furthermore, the water guide bucket is located directly below the sewage filter screen.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a rotating limiting roller to facilitate the horizontal movement of the wastewater filter membrane onto the support plate. The pushing force of the outward-expanding spring ensures the limiting roller presses down on the wastewater filter membrane, preventing displacement during wastewater flow. A sealing gasket enhances the friction between the limiting roller and the wastewater filter membrane, improving the stability of the membrane's positioning. The connecting frame not only assists in positioning the membrane but also, through a reciprocating screw, drives the adjusting plate and connecting frame to adjust the flow position of the wastewater on the membrane surface, preventing imperfections and resulting in more accurate wastewater testing values. A water quality analyzer facilitates the testing of the filtered wastewater, allowing for the determination of the membrane's filtration performance.

Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-7 As shown, this utility model is a filtration performance testing device for wastewater filtration membrane production, including a housing 1. The housing 1 is equipped with a limiting component 2 and an auxiliary component 3. The limiting component 2 is used to limit the wastewater filtration membrane, and the auxiliary component 3 is used for horizontal translation to adjust the position of the wastewater filtration membrane for wastewater detection. Support plates 4 are connected to the inner walls on both sides of the housing 1. Wastewater filter screens are placed on the top of the two support plates 4. A drive source 5 is connected to one side of the housing 1. The power output end of the drive source 5 is powered and connected to the auxiliary component 3. A protective cover 6 is connected to the top of the housing 1. A water quality analyzer 7 is connected to the inside of the protective cover 6.

[0030] First, open the sealed door on the housing 1. Then, lift the limiting component 2 upwards and gradually move the sewage filter membrane onto the two support plates 4. The rebound reset action of the limiting component 2 then exerts a limiting force on the sewage filter membrane from top to bottom, pressing the membrane into place. Next, adjust the position of the auxiliary component 3 and filter the sewage through the auxiliary component 3 and then through the support plates 4. Finally, test the filtered sewage using a water quality analyzer 7 (model LH-P700). The measured parameters are used to determine the filtration performance of the filter membrane. The auxiliary component 3 not only facilitates the limiting of the sewage filter membrane but also allows for testing at multiple locations on the membrane to prevent sewage from failing to penetrate at different points, thus obtaining more accurate sewage test values.

[0031] The limiting component 2 helps to limit the position of the wastewater filter membrane, preventing it from shifting when wastewater is introduced. The auxiliary component 3 not only helps to limit the position of the wastewater filter membrane, but also adjusts the flow position of the wastewater within the membrane to prevent wastewater from failing to penetrate at different positions, thus obtaining more accurate wastewater detection values. The water quality analyzer 7 facilitates the testing of the filtered wastewater, and the detection values ​​of the wastewater facilitate the determination of the filtration performance of the wastewater filter membrane.

[0032] In one embodiment, the limiting component 2 includes two fixing plates 21, two connecting plates 23, four sealing gaskets 26, and four outward expansion springs 27. The two fixing plates 21 are symmetrically arranged on the inner walls of both sides of the housing 1. The bottom ends of the two fixing plates 21 are connected to two sliding rods 22. The inner side of each connecting plate 23 is slidably connected to the outer side of each pair of sliding rods 22. The bottom ends of the two connecting plates 23 are connected to two connecting shells 24. The inner sides of the four connecting shells 24 are rotatably connected to limiting rollers 25. The four sealing gaskets 26 are respectively disposed on the surface of the four limiting rollers 25. The four outward expansion springs 27 are respectively sleeved on the outer side of the four sliding rods 22.

[0033] First, open the sealed door on the housing 1. Then, lift the four connecting plates 23 upwards and gradually move the sewage filter membrane onto the two support plates 4 using the four rotating limiting rollers 25. Then, the elastic reset action of the four outward-expanding springs 27 generates a limiting force on the sewage filter membrane from top to bottom, thereby pressing and limiting the sewage filter membrane. The friction of the sealing gasket 26 increases the friction force of the limiting rollers 25 on the sewage filter membrane. Then, adjust the position of the auxiliary component 3 and filter the sewage through the auxiliary component 3 and then through the sewage filter membrane. Finally, the filtered sewage is tested by the LH-P700 water quality analyzer 7. The obtained numerical parameters are used to judge the filtration performance of the filter membrane. The auxiliary component 3 not only facilitates the auxiliary limiting function of the sewage filter membrane, but also allows the sewage to be tested at multiple positions on the sewage filter membrane to prevent sewage from failing to penetrate at different positions, thus obtaining more accurate sewage test values.

[0034] The rotating limiting roller 25 facilitates the horizontal placement of the wastewater filter membrane onto the support plate 4. The pushing force of the outward-expanding spring 27 helps the limiting roller 25 press down and limit the wastewater filter membrane, preventing displacement when wastewater is introduced. The sealing gasket 26 increases the friction between the limiting roller 25 and the wastewater filter membrane, improving the stability of the limiting effect. The auxiliary component 3 not only assists in limiting the wastewater filter membrane but also adjusts the flow position of the wastewater within the membrane to prevent imperfections and obtain more accurate wastewater detection values. The water quality analyzer 7 facilitates the testing of the filtered wastewater, and the test results provide information on the filtration performance of the wastewater filter membrane.

[0035] In one embodiment, for the connecting plates 23, one side of each of the two connecting plates 23 is in contact with the inner wall of the housing 1, thereby facilitating the improvement of the stability of the movement of the connecting plates 23.

[0036] In one embodiment, for the aforementioned expansion springs 27, the two ends of each pair of expansion springs 27 are respectively connected to the bottom end of each fixed plate 21 and the top end of each connecting plate 23, thereby facilitating the downward movement of the limiting roller 25 to press the sewage filter membrane down and limit it through the elastic reset force.

[0037] In one embodiment, the auxiliary component 3 includes a reciprocating screw 31, a connecting frame 33, and a water guide 35. The reciprocating screw 31 is mounted on the power output end of the drive source 5. An adjusting plate 32 is slidably connected to the surface of the reciprocating screw 31. The top end of the adjusting plate 32 is in contact with the inner side of the top end of the housing 1. The connecting frame 33 is located at the bottom end of the adjusting plate 32. A water inlet pipe 34 is connected to one side of the connecting frame 33. The surface of the water inlet pipe 34 is connected to the interior of the other side of the housing 1. The water guide 35 is located inside the housing 1. A water outlet pipe 36 is connected to the bottom end of the water guide 35. The surface of the water outlet pipe 36 is connected to the interior of one side of the housing 1, thereby facilitating the discharge of filtered wastewater for subsequent testing.

[0038] In one embodiment, the water guide hopper 35 is located directly below the sewage filter screen, thereby facilitating sewage flow.

[0039] In summary, using the above-mentioned technical solution of this utility model, firstly, the sealed door on the housing 1 is opened. Then, the four connecting plates 23 are lifted upwards, and the sewage filter membrane is gradually moved horizontally onto the two support plates 4 by the four rotating limiting rollers 25. Then, the elastic reset action of the four outward-expanding springs 27 generates a limiting force on the sewage filter membrane from top to bottom, thereby pressing and limiting the sewage filter membrane. The friction of the sealing gasket 26 increases the friction force of the limiting rollers 25 on the sewage filter membrane. Then, the drive source 5 drives the reciprocating screw 31 to rotate, and the reciprocating screw 31 drives the adjusting plate 32 to move horizontally, thereby driving the connecting frame 33 to move horizontally against the surface of the sewage filter membrane. The position of the connecting frame 33 and the sewage filter membrane can be adjusted to perform sewage detection at one position of the sewage filter membrane. The connecting frame 33 can also be moved back and forth on the surface of the sewage filter membrane to allow the sewage to move at different positions on the surface of the sewage filter membrane to obtain sewage test results. At this time, the sewage is introduced into the tank 1 through the inlet pipe 34 and flows out through the connecting frame 33, the sewage filter membrane, the guide bucket 35 and the outlet pipe 36. The sewage is filtered through the sewage filter membrane. Finally, the outflowing sewage is tested by the LH-P700 water quality tester 7. The filtration performance of the sewage filter membrane is judged by measuring the various numerical parameters. The connecting frame 33 not only facilitates the auxiliary limiting function of the sewage filter membrane, but also allows the sewage to be tested at multiple positions on the sewage filter membrane to prevent the sewage from not penetrating at different positions on the sewage filter membrane, thereby obtaining more accurate sewage test values.

[0040] Through the above technical solution, the rotating limiting roller 25 facilitates the horizontal placement of the sewage filter membrane on the support plate 4. The pushing force of the outward-expanding spring 27 facilitates the downward pressure and limiting of the sewage filter membrane by the limiting roller 25, preventing displacement of the sewage filter membrane when sewage is introduced. The sealing gasket 26 increases the friction between the limiting roller 25 and the sewage filter membrane, thereby improving the stability of the limiting of the sewage filter membrane. The connecting frame 33 not only assists in limiting the sewage filter membrane, but also, through the reciprocating screw 31 driving the adjusting plate 32 and the connecting frame 33 to move back and forth, can adjust the flow position of sewage on the surface of the sewage filter membrane to prevent sewage from failing to penetrate at different positions of the sewage filter membrane, thereby obtaining more accurate sewage detection values. The water quality analyzer 7 facilitates the detection of the filtered sewage, and the detection values ​​of the sewage facilitate the determination of the filtration performance of the sewage filter membrane.
