Description

Technical Field

[0001] The invention relates to the technical field of membrane filter plate detection, in particular to a high-efficiency double-diaphragm flow guide filter plate and filtering performance detection equipment. Background Art

[0002] High-efficiency double-diaphragm filter plates are high-efficiency filter components used in filter presses or other filtration equipment. Their core feature is a double-diaphragm design that significantly improves filtration efficiency and reduces filter cake moisture. This technology is widely used in a variety of fields, including industrial wastewater treatment, sludge dewatering, and food processing.

[0003] For example, a Chinese patent with the announcement number CN218474993U discloses a diaphragm plate detection device, which mainly includes a pressing block, a transparent hose, a lip-shaped sealing ring, and a quick connector. The pressing block is set at the top center of the side of the diaphragm plate, with an air source channel in the center and a pressing vent hole on the side. The quick connector connects the transparent hose, the pressing vent hole and the core plate air inlet hole. By observing the color of the transparent hose, it is simple and clear to judge whether the diaphragm plate is damaged, thereby improving the detection level of diaphragm plate damage, saving labor time and improving maintenance efficiency.

[0004] However, the above detection device still has some shortcomings in actual use:

[0005] 1. First, when the existing device inspects the product, it determines whether the membrane plate is damaged by observing the color of the transparent hose, which is simple and clear. However, it should be noted that it can only detect the quality of the product and cannot present the product's extreme performance, optimal performance and safety performance through data. As a result, the results of product testing lack data support and are uncertain.

[0006] 2. Secondly, when testing the filtration performance of the product, the existing testing method is ineffective and can only determine whether the membrane plate is damaged. It cannot simulate the performance of the product in real conditions, resulting in insufficient rigor in product testing.

[0007] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing detection devices. Summary of the Invention

Specific implementation mode

[0042] The following is combined with Figures 1-13 to further elaborate on this application.

[0043] The embodiment of this application discloses a high - efficiency double - diaphragm diversion filter plate and a filtration performance detection device; mainly applied in the process of detecting the performance of the high - efficiency double - diaphragm diversion filter plate A.

[0044] First of all, this application proposes a high - efficiency double - diaphragm diversion filter plate A, which relates to the field of water treatment technology, especially a high - efficiency double - diaphragm diversion filter plate A used to improve the filtration efficiency and speed. This filter plate 10 is applicable to various water treatment systems, such as industrial wastewater treatment, domestic sewage treatment, and drinking water purification, etc.

[0045] The traditional design of the filter plate 10 often has problems such as uneven water flow distribution, low filtration efficiency, high energy consumption, and high moisture content of the filter cake during the filtration process. These problems not only affect the overall performance of the water treatment system but also increase the operation cost and maintenance difficulty.

[0046] Therefore, this application proposes a brand - new high - efficiency double - diaphragm diversion filter plate A. Its technical purpose is to achieve uniform water flow distribution, improve filtration efficiency, reduce energy consumption, and reduce the moisture content of the filter cake by optimizing the structure of the filter plate 10 and adding a double - diaphragm design.

[0047] Refer to Figure 1 、 Figure 2 and Figure 3As shown, it includes a filter plate 10 and a double diaphragm membrane 11. The double diaphragm membrane 11 is fixed on the front and back sides of the filter plate 10 and its size is adapted to the filter plate 10 to form the front and back filter chambers and the tympanic membrane cavity.

[0048] A feed hole 12 is provided in the middle of the filter plate 10. The filter plate 10 is also provided with a drainage hole 13, a water pressing hole 15, an exhaust hole 14 and an air pressing hole 16. Through the complex channel design, the water flow is divided into multiple branches and then merged.

[0049] The main body of the filter plate 10 is made of high-strength, corrosion-resistant material to ensure long-term stable operation.

[0050] A plurality of feed holes 12, drainage holes 13, air vents 14 and pressing holes are evenly distributed on the filter plate 10 to achieve uniform distribution of water flow and efficient filtration.

[0051] The double diaphragm membrane 11 is fixed on the front and back sides of the filter plate 10 to form the front and back filter chambers and the tympanic cavity.

[0052] The double diaphragm structure can increase the contact area between water flow and the filter surface, thereby improving filtration efficiency.

[0053] At the same time, the double diaphragm design can reduce the resistance of water flow and reduce energy consumption.

[0054] The filter plate 10 is provided with a complex guide channel, so that the water flow can be divided into multiple branches and then merged when passing through the filter plate 10, thereby increasing the contact time and contact area between the water flow and the surface of the filter plate 10.

[0055] The design of the diversion channel can also ensure uniform distribution of water flow on the filter plate 10, avoiding the occurrence of local overload and blockage.

[0056] In addition, the present application also provides a detection device for performing performance testing on the above-mentioned high-efficiency double-diaphragm guide filter plate A, as shown below:

[0057] Reference Figure 1 and Figure 4 As shown, the high-efficiency double-diaphragm guide filter plate filtration performance testing equipment includes a working platform 2, on which is provided a continuous conveying portion 3 for continuously conveying the high-efficiency double-diaphragm guide filter plate A, driving the uninterrupted detection of the high-efficiency double-diaphragm guide filter plate A, and the working platform 2 is also provided with a detection portion 4 for detecting the high-efficiency double-diaphragm guide filter plate A.

[0058] The continuous conveying part 3 is also provided with a clamping member 32, which includes a plurality of plug-in columns 323 for plugging into the water squeezing holes 15 on the filter plate 10. A vibration member 7 for controlling the vibration of the high-efficiency double-diaphragm guide filter plate A is also provided on one side of the plug-in column 323.

[0059] In this application, the high-efficiency double-diaphragm guide filter plate A is conveyed in an assembly line manner by a continuous conveying unit 3, ensuring efficient testing of the high-efficiency double-diaphragm guide filter plate A. While the high-efficiency double-diaphragm guide filter plate A is being conveyed, the clamping member 32 clamps and secures the high-efficiency double-diaphragm guide filter plate A. The testing unit 4 then performs a double-sided test of the expansion pressure of the double-diaphragm diaphragm 11, simulating the high-efficiency double-diaphragm guide filter plate A during material dehydration and compression to determine whether the pressure generated is sufficient and whether the double-diaphragm diaphragms 11 on both sides of the high-efficiency double-diaphragm guide filter plate A exert the same pressure. Simultaneously, with the assistance of a vibrating member 7, the vibrations generated by the operation of the high-efficiency double-diaphragm guide filter plate A during operation are further simulated to observe the filtering performance of the high-efficiency double-diaphragm guide filter plate A in a vibrating environment.

[0060] See Figure 4 and Figure 5 As shown, it is a structural schematic diagram of the conveying of the high-efficiency double-diaphragm guide filter plate A in this application; the continuous conveying part 3 includes four groups of continuous conveying rollers 30 distributed in a rectangular shape on the working platform 2, and a continuous conveying belt 31 is provided between the four groups of continuous conveying rollers 30, and the continuous conveying belt 31 is provided with clamping parts 32 for clamping the filter plate 10 at equal intervals.

[0061] One side of the continuous conveying roller 30 is connected to a continuous conveying motor 33 disposed inside the working platform 2 .

[0062] During specific implementation, the continuous conveying motor 33 is started, and the output end of the continuous conveying motor 33 drives the continuous conveying roller 30 on one side to rotate. During the rotation process, the continuous conveying roller 30 can drive the clamping parts 32 arranged at equal intervals on the continuous conveying belt 31 to rotate intermittently at a uniform speed. At this time, during the intermittent stop process, the high-efficiency double-diaphragm guide filter plate A is installed on the clamping part 32 for limiting, and then the filtration performance can be tested by the detection part 4.

[0063] See Figure 6 and Figure 7 The figure shows a schematic diagram of the structure for clamping the high-efficiency double-diaphragm guide filter plate A in the present application; the clamping member 32 includes a fixed plate 320 installed on the continuous conveyor belt 31, and two groups of symmetrical and telescopic longitudinal blocks 321 are slidingly provided on the side walls of the fixed plate 320, and horizontal blocks 322 are telescopically installed on both sides of the length direction of the longitudinal blocks 321, and the tops of the horizontal blocks 322 are installed with plug-in columns 323 for plugging the exhaust holes 14 and the feed holes 12 on the filter plate 10, and the plug-in columns 323 are slidably installed with supporting rings 324 along the height direction, and a supporting spring 325 is provided between the supporting ring 324 and the horizontal block 322 and is sleeved on the plug-in columns 323.

[0064] A downward pressing linkage guide rail 328 is installed on the work platform 2 through a bracket. The filter plate 10 to be tested on the work platform 2 is limited.

[0065] In specific implementation, before testing the high-efficiency double-diaphragm guide filter plate A, the spacing between the four groups of rectangularly distributed plug-in columns 323 on the fixed block is first adjusted so that their spacing is the same as the four drainage holes 13 on the high-efficiency double-diaphragm guide filter plate A that needs to be processed next.

[0066] Then, align the four drainage holes 13 of the high-efficiency double-diaphragm guide filter plate A with the plug-in columns 323 and insert them into the four plug-in columns 323. At the same time, the high-efficiency double-diaphragm guide filter plate A is supported by the supporting rings 324 on the four groups of plug-in columns 323 to ensure that the high-efficiency double-diaphragm guide filter plate A is in a suspended state.

[0067] Then the continuous conveyor belt 31 continues to rotate, controlling the clamping part 32 on which the high-efficiency double-diaphragm guide filter plate A has been installed to move to the area to be detected of the detection part 4. At this time, the linkage guide rail squeezes the high-efficiency double-diaphragm guide filter plate A so that it can be restricted on the plug-in column 323. The linkage guide rail presses down the high-efficiency double-diaphragm guide filter plate A, and the supporting ring 324 and the supporting spring 325 lift the high-efficiency double-diaphragm guide filter plate A. Therefore, the two cooperate with each other to complete the clamping of the high-efficiency double-diaphragm guide filter plate A.

[0068] Mounted on the fixed block is a number one electric push rod 326 that controls the telescopic movement of the longitudinal block 321. Connected to the longitudinal block 321 is a bidirectional electric push rod 327 that controls the outward extension and retraction of the horizontal block 322. The number one electric push rod 326 controls the extension and retraction of the two longitudinal blocks 321 on the fixed block, while the bidirectional electric push rod 327 controls the extension and retraction of the two horizontal blocks 322 on the longitudinal block 321. This, in turn, ensures that the plug-in column 323 can limit the position of high-efficiency dual-diaphragm guide filter plates A of different sizes, improving the device's applicability.

[0069] After the high-efficiency double-diaphragm flow guide filter plate A is clamped, it is fixed horizontally and its filtration performance can be tested as shown below:

[0070] See Figure 8 and Figure 9 As shown, the detection part 4 includes a connecting pipe 40 connected to the water squeezing hole 15 on the filter plate 10, and a water pump known from the outside is installed on the connecting pipe 40.

[0071] The detection part 4 includes a connecting pipe 40 connected to the water squeezing hole 15 on the filter plate 10 , and a water pump known from the outside is installed on the connecting pipe 40 .

[0072] On the working platform 2, a horizontally distributed detection push rod 41 is installed. There is also a vertical frame 42 installed on the working platform 2. The detection push rod 41 is arranged on the vertical frame 42, and the detection push rod 41 is horizontally distributed. On the output end of the detection push rod 41, a U-shaped frame 49 is installed. On one side of the U-shaped frame 49, detection blocks 43 are symmetrically and slidably installed along the height direction. At the bottom of the detection blocks 43, a pressure detection device 45 is provided through a number of detection springs 44.

[0073] On the vertical frame 42, a guide plate 46 is installed. On the guide plate 46, two groups of symmetric opening and closing guide grooves 47 are provided. On the detection blocks 43, guide columns 48 are installed, and the guide columns 48 are slidably arranged in the opening and closing guide grooves 47.

[0074] During specific implementation, start the detection push rod 41. The output end of the detection push rod 41 pushes the detection blocks 43 slidably installed at its upper end through the U-shaped frame 49 to move towards the direction of the high-efficiency double diaphragm diversion filter plate A until the pressure detection devices 45 on the two detection blocks 43 are located at the upper and lower ends of the high-efficiency double diaphragm diversion filter plate A, and the two pressure detection devices 45 are abutted against the upper and lower ends of the high-efficiency double diaphragm diversion filter plate A.

[0075] When the detection push rod 41 controls the movement of the two detection blocks 43 through the U-shaped frame 49, the two detection blocks 43 approach each other along the opening and closing guide grooves 47 on the guide plate 46 through the guide columns 48, and while approaching each other, the detection blocks 43 still move towards the direction of the high-efficiency double diaphragm diversion filter plate A until the pressure detection devices 45 on the two detection blocks 43 are both abutted against the two sides of the high-efficiency double diaphragm diversion filter plate A.

[0076] When the detection push rod 41 moves, the connecting pipe 40 is also inserted into the water pressure squeezing holes 15 on the side wall of the high-efficiency double diaphragm diversion filter plate A. Then the water pump is started to introduce the liquid into the tympanic membrane cavities on the front and back sides of the high-efficiency double diaphragm diversion filter plate A through the connecting pipe 40, so that the double diaphragm membranes 11 of the high-efficiency double diaphragm diversion filter plate A bulge.

[0077] At this time, the double diaphragm membranes 11 will squeeze the pressure detection devices 45. After the pressure detection devices 45 are subjected to pressure, they start to record the external pressure received and display the magnitude of the pressure. Then, stand still for a period of time and observe whether the pressure value recorded by the pressure detection devices 45 changes.

[0078] If the pressure value recorded by the pressure detection devices 45 gradually becomes smaller after reaching the maximum value, it indicates that there is a leakage point between the double diaphragm membranes 11 and the filter plate 10 of the high-efficiency double diaphragm diversion filter plate A.

[0079] If the pressure value recorded by the pressure detection devices 45 remains unchanged after reaching the maximum value, it indicates that the sealing between the double diaphragm membranes 11 and the filter plate 10 of the high-efficiency double diaphragm diversion filter plate A is good.

[0080] Furthermore, the water pump continues to operate, continuously supplying water into the tympanic cavity. At this time, the double-diaphragm membrane 11 continuously bulges outward, squeezing the pressure detection device 45 as it continues to bulge outward. When the double-diaphragm 11 can no longer bulge outward, the water supply is stopped. The pressure recorded by the pressure detection device 45 at this time is the maximum safe pressure that the double-diaphragm 11 can withstand. If the water pump continues to operate, causing the double-diaphragm 11 to rupture, the pressure recorded by the pressure detection device 45 at this time is the maximum limit pressure that the double-diaphragm 11 can withstand.

[0081] Furthermore, in order to ensure the accuracy and efficiency of the performance test results of the high-efficiency double-diaphragm guide filter plate A, the present application also proposes a vibration member 7, which is specifically shown below:

[0082] See Figure 10 、 Figure 11 and Figure 12 As shown, the vibration member 7 includes a limit frame 70 integrally connected to the supporting ring 324 , and two symmetrical vibration wheels 71 are rotatably arranged in the limit frame 70 to knock the filter plate 10 .

[0083] During specific implementation, when liquid is introduced into the high-efficiency double-diaphragm guide filter plate A and begins to collide, the vibration wheel 71 rotates, and the vibration wheel 71 knocks on the high-efficiency double-diaphragm guide filter plate A to make it vibrate. At this time, in the vibrating state, it is detected whether the filtering performance of the high-efficiency double-diaphragm guide filter plate A is the same as the filtering performance in the non-vibrating state.

[0084] A movable groove 72 for the sliding of the limit frame 70 is provided in the middle of the plug-in column 323. The two vibration wheels 71 are connected by a synchronous belt 73 to ensure that the two vibration wheels 71 rotate synchronously. The vibration wheel 71 on one side is connected to a vibration motor installed on the outer wall of the limit frame 70 through a bracket. The high-efficiency double-diaphragm guide filter plate A is knocked by the vibration wheel 71 to simulate the vibration generated by the filter plate 10 of the high-efficiency double-diaphragm guide filter plate A when materials, gases and liquids are passed through it during operation, so as to judge whether the vibration affects the filtering performance of the filter plate 10 and the double-diaphragm diaphragm 11.

[0085] It should be noted that the vibration motor is shown in the diagram but not labeled as an existing known structure.

[0086] During specific implementation, the vibration motor is started, and the output end of the vibration motor controls the rotation of the vibration wheel 71 on one side, and a synchronous belt 73 is connected between the two vibration wheels 71, so that the two vibration wheels 71 can rotate synchronously. During the synchronous rotation process, the two vibration wheels 71 can knock on the high-efficiency double-diaphragm guide filter plate A, causing it to vibrate on the plug-in column 323. During the vibration process, the filtration performance test is still carried out.

[0087] See Figure 12 and Figure 13 As shown, the vibration wheel 71 is also provided with a lifting component 8 for controlling its lifting. The lifting component 8 includes movable frames 85 arranged on both sides of the vibration wheel 71. The movable frames 85 are slidingly distributed along the height direction of the limit frame 70, and the limit frame 70 is symmetrically provided with a control screw 80 and a control column 81 in the width direction. The two movable frames 85 are respectively provided on the control screw 80 and the control column 81. A number one bevel gear 82 is installed on one side of the control screw 80, and a number two bevel gear 83 is engaged with the number one bevel gear 82. A control rod 84 for controlling its rotation is installed on the back side of the number two bevel gear 83. The control rod 84 is rotatably provided on the limit frame 70 and the supporting ring 324 and extends outward.

[0088] Furthermore, in order to ensure the accuracy of the detection, the present application can also control the vibration frequency of the vibration wheel 71 to detect the filtering performance of the high-efficiency double-diaphragm guide filter plate A through different degrees of vibration.

[0089] During specific implementation, the control rod 84 is rotated, and the second bevel gear 83 on the control rod 84 drives the first bevel gear 82 to rotate. When the first bevel gear 82 rotates, it drives the control screw 80 to rotate. When the control screw 80 rotates, the movable frame 85 at its upper end can move along the height direction of the limit frame 70.

[0090] When a greater degree of vibration is required, the control lever 84 is rotated to drive the movable frame 85 and the vibration wheel 71 to move upward. At this time, the vibration wheel 71 rotates to increase the vibration amplitude of the high-efficiency double-diaphragm guide filter plate A.

[0091] When the vibration level is low, the control lever 84 is rotated to drive the movable frame 85 and the vibration wheel 71 to move downward. At this time, the vibration wheel 71 rotates to reduce the vibration amplitude of the high-efficiency double-diaphragm guide filter plate A.

[0092] During operation: The first step is to adjust the spacing of the four groups of rectangularly distributed plug-in columns 323 on the fixed block before testing the high-efficiency double-diaphragm guide filter plate A so that their spacing is the same as the four drainage holes 13 on the high-efficiency double-diaphragm guide filter plate A that needs to be processed next.

[0093] Step 2: Align the four drainage holes 13 of the high-efficiency double-diaphragm flow guide filter plate A with the plug-in posts 323, inserting the plate onto the four plug-in posts 323. Simultaneously, the supporting collars 324 on the four sets of plug-in posts 323 support the high-efficiency double-diaphragm flow guide filter plate A, ensuring that the plate A remains suspended. The continuous conveyor belt 31 then continues to rotate, controlling the clamping member 32, onto which the high-efficiency double-diaphragm flow guide filter plate A is mounted, to move to the area to be inspected in the inspection unit 4.

[0094] Step 3: When the continuous conveyor belt 31 rotates to the area to be detected, the linkage guide rail presses down the high-efficiency double diaphragm diversion filter plate A, and the supporting collar 324 and the supporting spring 325 lift the high-efficiency double diaphragm diversion filter plate A. Therefore, the clamping of the high-efficiency double diaphragm diversion filter plate A can be completed by their mutual cooperation.

[0095] Step 4: Connect the connecting pipe 40 to the high-efficiency double diaphragm diversion filter plate A, start the detection push rod 41, and the output end of the detection push rod 41 pushes the detection block 43 slidably installed at its upper end through the C-shaped frame to move towards the high-efficiency double diaphragm diversion filter plate A until the pressure detection devices 45 on the two detection blocks 43 are located at the upper and lower ends of the high-efficiency double diaphragm diversion filter plate A, and the two pressure detection devices 45 abut against the upper and lower ends of the high-efficiency double diaphragm diversion filter plate A.

[0096] When the detection push rod 41 controls the movement of the two detection blocks 43 through the C-shaped frame, the two detection blocks 43 approach each other along the opening and closing guide grooves 47 on the guide plate 46 through the guide columns 48, and the detection blocks 43 still move towards the high-efficiency double diaphragm diversion filter plate A while approaching each other until the pressure detection devices 45 on the two detection blocks 43 abut against both sides of the high-efficiency double diaphragm diversion filter plate A.

[0097] Step 5: Then the water pump is started to introduce the liquid into the tympanic cavities on the front and back sides of the high-efficiency double diaphragm diversion filter plate A through the connecting pipe 40, so that the double diaphragm membranes 11 of the high-efficiency double diaphragm diversion filter plate A bulge.

[0098] At this time, the double diaphragm membranes 11 will squeeze the pressure detection devices 45, and the pressure detection devices 45 start to record the external pressure received after being pressured and display the magnitude of the pressure. Then, after standing for a period of time, observe whether the pressure value recorded by the pressure detection devices 45 changes.

[0099] If the pressure value recorded by the pressure detection devices 45 gradually becomes smaller after reaching the maximum value, it indicates that there is a leakage point between the double diaphragm membranes 11 and the filter plate 10 of the high-efficiency double diaphragm diversion filter plate A.

[0100] If the pressure value recorded by the pressure detection devices 45 remains unchanged after reaching the maximum value, it indicates that the sealing between the double diaphragm membranes 11 and the filter plate 10 of the high-efficiency double diaphragm diversion filter plate A is good.

[0101] Step 6: To ensure the accuracy of the detection results, after the initial filtration performance detection of the high-efficiency double diaphragm diversion filter plate A is completed, the vibration wheel 71 rotates, and the vibration wheel 71 knocks on the high-efficiency double diaphragm diversion filter plate A to make it vibrate. At this time, in the vibrating state, detect whether the filtration performance of the high-efficiency double diaphragm diversion filter plate A is the same as that in the non-vibrating state.

[0102] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
