Description

Technical Field

[0001] This invention belongs to the field of wastewater filtration and separation technology, and more specifically, relates to a wastewater filtration device based on a hollow fiber ultrafiltration membrane filter element. Background Technology

[0002] Hollow fiber ultrafiltration membrane cartridges are a type of filter material that uses hollow fiber ultrafiltration membranes as its core material. Under certain pressure, they utilize the micropores of the membrane fibers to sieve and trap suspended solids, colloids, large organic molecules, microorganisms, and other pollutants in wastewater, achieving wastewater purification and separation. Currently, wastewater purified by hollow fiber ultrafiltration membrane cartridges contains large suspended impurities. Because the pre-inlet pipe of traditional hollow fiber ultrafiltration membrane cartridge purification equipment lacks the ability to trap large suspended impurities, these impurities easily become stuck in the micropores of the membrane fibers, causing blockages. This leads to a sharp drop in filter cartridge filtration flux, requiring frequent cleaning or replacement, thus increasing the operating costs of the wastewater purification equipment. Furthermore, during the purification process, it is impossible to monitor the filtration capacity of each set of hollow fiber ultrafiltration membrane cartridges in real time, making it difficult for water purification operators to promptly identify and replace clogged hollow fiber ultrafiltration membrane cartridges. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a wastewater filtration device based on a hollow fiber ultrafiltration membrane cartridge to solve the problems that the inlet pipe of traditional hollow fiber ultrafiltration membrane cartridge purification equipment does not have the ability to intercept large particulate suspended impurities and cannot monitor the water purification filtration capacity of the hollow fiber ultrafiltration membrane cartridge in real time.

[0005] Furthermore, the suspended impurity filtration device includes a scraper motor, a water pipe shell, a sedimentation collection tank, a filter plate, a scraper frame, a support frame, and a transmission column. A scraper motor is installed at the top of the water pipe shell, and a transmission column is mounted on the motor shaft of the scraper motor. A support frame is rotatably connected to the outer side of the transmission column. The water pipe shell is welded to the left and right ends of the support frame. A filter plate is welded to the inner side of the water pipe shell near the center. The filter plate is densely covered with vertically penetrating filter holes. An inlet is located near the bottom of the outer side of the water pipe shell, and a water pump is installed at the inlet. An outlet is located near the top of the outer side of the water pipe shell, and a water distribution pipe is installed at the outlet. An opening is located at the bottom of the water pipe shell, and threads are present on the inner side of the opening. A sedimentation collection tank is screwed onto the threaded part at the bottom of the water pipe shell. A scraper frame is installed at the bottom of the transmission column.

[0006] Furthermore, the scraper frame has a circular disc structure, and the outer side of the circular disc structure of the scraper frame is provided with two sets of rectangular scrapers, with the upper side of the scrapers attached to the lower side of the filter plate.

[0007] Furthermore, the filtration flow monitoring device includes a manifold, a velocity pipe, a Hall sensor, a flow guide frame, a turbofan, and a rotating rod. The inlet of the manifold is installed at the outlet of the hollow fiber ultrafiltration membrane filter element assembly, and the outlet of the manifold is equipped with a velocity pipe. A Hall sensor is installed on the outer side of the velocity pipe, and an electric water valve is installed at the front end of the velocity pipe. A filter water pipe is installed at the other end of the electric water valve. A turbofan, made of permanent magnet material, is welded to the center of the outer side of the rotating rod. A flow guide frame is rotatably connected to the outer side of the rotating rod near the front and rear ends, and a velocity pipe is welded to the outer side of the flow guide frame.

[0008] Furthermore, the number of the flow guides is two sets, and each set of flow guides has three sets of protruding plates on its outer side, which are arranged in a ring array around the horizontal central axis of the flow guide.

[0009] Furthermore, the filter water pipe is a cylindrical tube structure with an opening at the left end. Five sets of water inlets are provided on the outer side of the cylindrical tube structure near the rear side, and an electric water valve is installed at the end of each set of water inlets.

[0010] Furthermore, the number of the support frame is three sets, each set of the support frame is a U-shaped structure, the front side of the U-shaped structure of the support frame is provided with five sets of through holes, and each set of through holes of the support frame is equipped with an ultrasonic generator, which is attached to the outer side of the hollow fiber ultrafiltration membrane filter element assembly.

The sedimentation collection tank and the filter plate are vertically opposite each other.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, on the one hand, large particulate suspended impurities in sewage are pre-intercepted by the permeable holes on the surface of the filter plate inside the water pipe shell of the suspended impurity filtration device, which prevents impurities from flowing directly into the hollow fiber ultrafiltration membrane filter element assembly. This reduces the probability of clogging of the ultrafiltration membrane filter element, extends the service life of the ultrafiltration membrane filter element, and reduces the frequency of filter element replacement and equipment maintenance costs. On the other hand, the scraping motor drives the scraper to rotate on the lower side of the filter plate to scrape the suspended impurity particles accumulated on the surface of the filter plate, preventing the filter plate itself from clogging and causing sewage back pressure, and ensuring that the filter plate filtration is continuously effective.

[0013] 2. In this invention, the water flow inside the flow tube impacts the turbofan made of permanent magnet material to rotate at high speed. The Hall sensor captures the changes in the magnetic field generated by the rotation of the turbofan in real time and generates a pulse signal. After the signal is transmitted to the controller, the water flow rate is calculated. The operator infers the filtration and water permeability blockage of the filter element based on the water flow rate of the filter element. This ensures that the operator can intuitively grasp the working status of each filter element and promptly detect blocked filter elements, thus improving the accuracy and convenience of operation and maintenance.

[0027] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0028] like Figures 1-12As shown, this invention provides a wastewater filtration device based on a hollow fiber ultrafiltration membrane filter element, including a base plate 1; a support 2 is welded to the upper side of the base plate 1; a bracket 17 is bolted to the upper side of the support 2, a controller 6 is mounted on the front side of the bracket 17, an ultrasonic controller 3 and a water pump 4 are mounted on the upper side of the support 2, and an inlet pipe 5 is installed at the inlet end of the water pump 4; it also includes a water distribution pipe 7, a concentration pipe 10, a filtration flow monitoring device 11, a suspended impurity filtration device 14, and a hollow fiber ultrafiltration membrane filter element. The filter membrane filter element assembly 16; the outer side of the water distribution pipe 7 is welded with a vertical plate frame 15, the bottom end of the vertical plate frame 15 is welded with a base plate 1, the outer side of the water distribution pipe 7 is provided with five sets of drain outlets, and each set of drain outlets of the water distribution pipe 7 is equipped with an electric water valve 8; the hollow fiber ultrafiltration membrane filter element assembly 16 is equipped with an electric water valve 8 at both the water inlet end and the concentration drain end; the outer side of the concentration pipe 10 is equipped with an electric water valve 8, the outer side of the concentration pipe 10 is welded with a vertical plate frame 15, and a support plate frame 12 is bolted to the vertical plate frame 15.

[0029] In this embodiment of the invention, the suspended impurity filtration device 14 includes a scraping motor 1401, a water pipe shell 1402, a sedimentation collection tank 1403, a filter plate 1404, a scraper frame 1405, a support frame 1406, and a transmission column 1407. The scraping motor 1401 is mounted on the top of the water pipe shell 1402. The transmission column 1407 is mounted on the motor shaft of the scraping motor 1401. The support frame 1406 is rotatably connected to the outer side of the transmission column 1407. The water pipe shell 1402 is welded to the left and right ends of the support frame 1406. The filter plate 1404 is welded to the inner side of the water pipe shell 1402 near its center. The filter plate 1404 has numerous through-holes on its upper surface, and these through-holes are aligned with the water pipe. The wastewater flowing inside the shell 1402 is filtered and intercepted for large suspended solids, preventing them from directly flowing into the hollow fiber ultrafiltration membrane filter element 16 and extending its filtration and purification lifespan. A water inlet is located near the bottom of the outer side of the water pipe shell 1402, and a water pump 4 is installed therein. An outlet is located near the top of the outer side of the water pipe shell 1402, and a water distribution pipe 7 is installed at the outlet. An opening is located at the bottom of the water pipe shell 1402, with threads on the inner side of the opening. A sedimentation collection tank 1403 is screwed onto the threaded bottom of the water pipe shell 1402. A scraper 1405 is installed at the bottom of the transmission column 1407.

[0030] In this embodiment of the invention, the scraper 1405 is a circular disc structure. Two sets of rectangular scrapers are provided on the outer side of the circular disc structure of the scraper 1405. The upper side of the scrapers is attached to the lower side of the filter plate 1404. During the rotation of the drive column 1407 driven by the scraping motor 1401, the drive column 1407 drives the scraper 1405, which is welded to its bottom end, to rotate on the lower side of the filter plate 1404. This causes the two sets of rectangular scrapers on the outer side of the scraper 1405 to scrape the particles accumulated on the surface of the filter plate 1404, preventing large suspended particles from accumulating at the water filtration holes of the filter plate 1404 under the impact of water flow. This prevents the filter plate 1404 from becoming clogged, causing sewage pressure buildup, and ensures the continuous and effective water filtration of the filter plate 1404.

[0031] In this embodiment of the invention, the filter flow monitoring device 11 includes a manifold 1101, a flow velocity pipe 1102, a Hall sensor 1103, a flow guide 1104, a turbofan 1105, and a rotating rod 1106. The inlet of the manifold 1101 is installed at the outlet of the hollow fiber ultrafiltration membrane filter element assembly 16, and the outlet of the manifold 1101 is equipped with the flow velocity pipe 1102. A Hall sensor 1103 is installed on the outer side of the flow velocity pipe 1102, and an electric water valve 8 is installed at the front end of the flow velocity pipe 1102. A filter water pipe 9 is installed at the other end of the electric water valve 8. A turbofan 1105 is welded to the center of the outer side of the rotating rod 1106. The turbofan 1105 is made of permanent magnet material. The flow guide 1104 is rotatably connected to the outer side of the rotating rod 1106 near both the front and rear ends. A flow velocity pipe 1102 is welded to the outer side of 104. The purified water discharged from the hollow fiber ultrafiltration membrane filter element assembly 16 is collected and converged into the flow velocity pipe 1102 through the manifold 1101. The turbofan 1105 rotates at high speed under the impact of the water flow. During the rotation, the blades of the turbofan 1105 pass through the detection end of the Hall sensor 1103 in sequence. The Hall sensor 1103 captures the magnetic field change generated by the rotation of the turbofan 1105 and generates a pulse signal. The Hall sensor 1103 transmits the detected pulse signal to the controller 6 through the wire. The controller 6 calculates and measures the rotation speed of the turbofan 1105 under the impact of the water flow and displays it in real time on the display panel of the controller 6. This allows the operator to infer the filtration and water permeability clogging of the hollow fiber ultrafiltration membrane filter element assembly 16 based on the flow rate of the purified water.

[0032] In this embodiment of the invention, there are two sets of flow guide frames 1104. Each set of flow guide frames 1104 has three sets of protruding plates on its outer side. The protruding plates are arranged in a ring array around the horizontal central axis of the flow guide frame 1104. The protruding plates of the flow guide frame 1104 guide and cut the purified water, so that the purified water impacts the turbofan 1105 smoothly, allowing the turbofan 1105 to rotate stably and ensuring the accuracy of the purified water flow rate detection.

[0033] In this embodiment of the invention, the filter water pipe 9 is a cylindrical tube structure with an opening at the left end. Five sets of water inlets are provided on the outer side of the cylindrical tube structure of the filter water pipe 9 near the rear side. Each set of water inlets of the filter water pipe 9 is equipped with an electric water valve 8 at the end. When it is necessary to remove and replace the clogged hollow fiber ultrafiltration membrane filter element 16 in the five sets of hollow fiber ultrafiltration membrane filter element assemblies 16, the control unit 6 controls the electric water valve 8 installed at the drain outlet of the corresponding water distribution pipe 7, the electric water valve 8 installed on the outer side of the concentration pipe 10, and the electric water valve 8 installed at the water inlet of the filter water pipe 9 to close simultaneously via a wire. This allows for the individual replacement of the clogged hollow fiber ultrafiltration membrane filter element 16 without stopping the water purification equipment, ensuring the purification efficiency of the water purification equipment for wastewater.

[0034] In this embodiment of the invention, there are three sets of support plates 12. Each set of support plates 12 has a U-shaped structure. The front side of the U-shaped structure of the support plate 12 has five sets of through holes. An ultrasonic generator 13 is installed in each set of through holes of the support plate 12. The ultrasonic generator 13 is attached to the outer side of the hollow fiber ultrafiltration membrane filter element assembly 16. When it is necessary to perform reverse negative pressure flushing on the hollow fiber ultrafiltration membrane filter element assembly 16, the ultrasonic controller 3 controls the ultrasonic generator 13 to emit ultrasonic waves to the hollow fiber ultrafiltration membrane filter element assembly 16 through the wire. This causes the dirt in the micropores of the hollow fiber ultrafiltration membrane filter element assembly 16 to vibrate and detach from the micropores under the cavitation effect of the ultrasonic waves, thereby improving the quality of negative pressure flushing and cleaning of the hollow fiber ultrafiltration membrane filter element assembly 16.

[0035] In this embodiment of the invention, the sedimentation collection tank 1403 is a cylindrical structure with an open upper side. The outer side of the cylindrical structure of the sedimentation collection tank 1403 is provided with a threaded structure near the top opening. The outer side of the sedimentation collection tank 1403 is threadedly connected to the threaded structure of the water pipe shell 1402. The sedimentation collection tank 1403 and the filter plate 1404 are vertically opposite each other. After the water purification equipment is stopped, the large particulate suspended impurities intercepted by the filter plate 1404 settle down into the cylindrical structure of the sedimentation collection tank 1403 by gravity for collection. Then, the sedimentation collection tank 1403 can be rotated and unscrewed from the threaded structure of the water pipe shell 1402 to remove the large particulate suspended impurities separately.

[0036] Specific usage and functions of this invention: In the process of purifying wastewater, the control unit 6 controls the water pump 4 via wires to inject wastewater from the inlet pipe 5 into the water pipe shell 1402. Wastewater containing large particles flows upwards along the water pipe shell 1402 towards the filter plate 1404. The wastewater continues to flow upwards through the permeable holes on the surface of the filter plate 1404, while the large particles are trapped and retained on the bottom side of the filter plate 1404. At this time, the control unit 6 controls the scraper motor 1401 via wires to drive the transmission column 1407 to rotate. This drives the scraper 1405, which is welded to the bottom, to rotate at high speed. The two sets of scrapers on the outer side of the scraper 1405 are attached to the lower side of the water-permeable holes to scrape away large particles of impurities that accumulate at the bottom of the water-permeable holes, preventing large particles of impurities from clogging the water-permeable holes of the filter plate 1404 and ensuring the water filtration efficiency of the water-permeable holes of the filter plate 1404. Then, the sewage flows into the water distribution pipe 7 through the outlet near the top on the outer side of the water pipe shell 1402. The water distribution pipe 7 then diverts the sewage to the center of the five sets of hollow fiber ultrafiltration membrane filter element assemblies 16 for further processing. The filtered and purified water flows into the manifold 1101 through the outlet of the hollow fiber ultrafiltration membrane filter element assembly 16. The manifold 1101 then channels the purified water into the flow velocity pipe 1102. At this point, the three sets of convex plates of the guide frame 1104 in the flow velocity pipe 1102 cut and guide the purified water, allowing it to stably impact the turbofan 1105. The turbofan 1105 rotates at high speed under the impact of the water flow. The blades of the turbofan 1105 pass sequentially through the detection end of the Hall sensor 1103, which captures the vortex. The magnetic field change generated by the rotation of the propeller 1105 generates a pulse signal. The Hall sensor 1103 transmits the detected pulse signal to the controller 6 through a wire. The controller 6 calculates and measures the rotation speed of the propeller 1105 under the impact of water flow and displays it in real time on the display panel of the controller 6. Then, the purified water flows from the flow pipe 1102 through the electric water valve 8 to the filter water pipe 9 for discharge. The concentrated drain end of the hollow fiber ultrafiltration membrane filter element assembly 16 discharges the concentrated liquid into the concentrated pipe 10, thereby completing the purification of wastewater.

[0037] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies. Any method that achieves the desired beneficial effect can be implemented. The ultrasonic controller 3, water pump 4, control unit 6, electric water valve 8, Hall sensor 1103, ultrasonic generator 13, scraper motor 1401, and hollow fiber ultrafiltration membrane filter element assembly 16 mentioned above are all common commercially available components. Upon purchase and use, simply connect them according to the instruction manual purchased with the product; therefore, further details are omitted here.
