Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, specifically to an anti-fouling device for recycling zinc-containing industrial wastewater membrane modules. Background Technology

[0002] Zinc-containing industrial wastewater refers to wastewater containing zinc and its compounds generated during industrial production processes. Zinc is an important non-ferrous metal, widely used in electroplating, battery manufacturing, metallurgy, chemical and other industries.

[0003] In membrane module systems, aeration pipes mitigate membrane fouling, enhance mass transfer efficiency, and prevent membrane module clogging through aeration. However, existing aeration pipes are generally fixed and can only prevent clogging in localized areas of the flat sheet membrane, not completely clean it, thus reducing the cleaning effect. To address these issues, the inventors propose an anti-clogging device for recycling zinc-containing industrial wastewater membrane modules. Utility Model Content

[0004] To address the issue that aeration pipes are typically fixed and can only prevent clogging in certain areas of the flat sheet membrane, but cannot completely clean it, this invention aims to provide an anti-clogging device for recycling membrane modules used in zinc-containing industrial wastewater treatment.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a device for preventing fouling and clogging of membrane components for recycling zinc-containing industrial wastewater, comprising a fixed frame, a water collection pipe, a hollow fiber membrane, and a connecting pipe. The water collection pipe is fixedly installed on the top surface of the fixed frame, the hollow fiber membrane is installed inside the fixed frame, and the connecting pipe is fixedly inserted between the hollow fiber membrane and the water collection pipe. A bearing plate is fixedly installed on the top surface of the fixed frame, the hollow fiber membrane is installed on the top surface of the bearing plate, a motor is installed on one side of the bearing plate, a bidirectional lead screw is fixedly installed at the output end of the motor, a threaded block is threaded on the outer surface of the bidirectional lead screw, a moving rod is fixedly installed on the top surface of the threaded block, a vertical plate is fixedly installed on the top surface of the moving rod, a connecting plate is fixedly installed on the top surface of the vertical plate, a limiting plate is fixedly installed on one side of the connecting plate, a fixed frame is fixedly installed on one side of the limiting plate, and an air outlet pipe is fixedly installed inside the fixed frame. An air outlet is fixed inside the pipe. An ear plate is fixed on the bottom surface of the support plate. An aeration pipe is fixed inside the ear plate. A conveying pipe is fixed on the outer surface of the aeration pipe. One end of the conveying pipe is fixed inside the air outlet pipe. First, zinc-containing industrial wastewater is poured into the filter frame, and then the screen inside the frame performs preliminary screening of the wastewater to remove suspended solids, colloids or organic impurities, thereby reducing membrane fouling. The aeration pipe is connected through an external pipeline, and then gas is conveyed into the aeration pipe, so that the gas can be conveyed from the conveying pipe and then discharged from the air outlet in the air outlet pipe. By turning on the motor, the bidirectional screw rotates, which causes the threaded block to slide in the support plate and drive the moving rod to move. At the same time, the vertical plate drives the connecting plate to move, which causes the limiting plate to drive the fixed frame and the air outlet pipe to move. Thus, when aerating the hollow fiber membrane to alleviate membrane fouling, the hollow fiber membrane can be thoroughly cleaned, improving the cleaning effect. By pulling the insert rod, the ring slides inside the sleeve, compresses the spring, and disengages the insert rod from the slot, thereby disassembling the frame to centrally process filtered impurities and prevent the screen from clogging.

[0006] Preferably, the bearing plate has a groove, the threaded block is slidably disposed in the groove, the bearing plate has a movable groove, the movable rod is slidably disposed in the movable groove, the bearing plate has a limit groove, the bottom surface of the connecting plate is fixedly provided with an auxiliary rod, the bottom surface of the auxiliary rod is fixedly provided with a movable rod, and the movable rod is slidably disposed in the limit groove.

[0007] Preferably, a filter frame is fixedly mounted on one side of the fixing frame, a water pump is installed on one side of the filter frame, a water pump pipe is fixedly mounted on one side of the water pump and is fixedly inserted into the filter frame, a drain pipe is fixedly mounted on one side of the water pump and one end of the drain pipe is fixedly installed in the water collection pipe, a frame is installed inside the filter frame, sleeves are fixedly mounted on both sides of the filter frame, a rod slides through the sleeve, a slot is opened in the frame and the rod is movably inserted into the slot, a ring is fixedly mounted on the outer surface of the rod and slides inside the sleeve, and a spring is fixedly connected between the inner wall of the sleeve and the ring.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The vertical plate drives the connecting plate to move, which in turn causes the limiting plate to move the fixed frame and the air outlet pipe. This allows for a thorough cleaning of the hollow fiber membrane during aeration to alleviate membrane fouling, thus improving the cleaning effect. 2. By pouring zinc-containing industrial wastewater into the filter frame, the screen inside the frame will initially screen out the wastewater to remove suspended solids, colloids, or organic impurities, thereby reducing membrane fouling.

An air outlet pipe 25 is fixedly installed inside the fixed frame 24, and an air outlet 26 is fixedly installed inside the air outlet pipe 25. An ear plate 21 is fixedly installed on the bottom surface of the support plate 2, and an aeration pipe 22 is fixedly installed inside the ear plate 21. A conveying pipe 23 is fixedly installed on the outer surface of the aeration pipe 22. One end of the conveying pipe 23 is fixedly installed inside the air outlet pipe 25 and connected to the aeration pipe 22 through an external pipeline. Gas is then conveyed into the aeration pipe 22, and the gas can be conveyed from the conveying pipe 23 and discharged from the air outlet 26 inside the air outlet pipe 25. By turning on the motor 3, the bidirectional lead screw 31 is rotated, which causes the threaded block 32 to slide inside the support plate 2 and drive the moving rod 33 to move. At the same time, the vertical plate 34 drives the connecting plate 37 to move, which causes the limiting plate 38 to drive the fixed frame 24 and the air outlet pipe 25 to move. Thus, when aerating the hollow fiber membrane 12 to alleviate membrane fouling, the hollow fiber membrane 12 can be thoroughly cleaned, improving the cleaning effect.

[0014] The bearing plate 2 has a groove 201, the threaded block 32 is slidably disposed in the groove 201, the bearing plate 2 has a movable groove 202, the movable rod 33 is slidably disposed in the movable groove 202, the bearing plate 2 has a limit groove 203, the bottom surface of the connecting plate 37 is fixedly provided with an auxiliary rod 35, the bottom surface of the auxiliary rod 35 is fixedly provided with a movable rod 36, and the movable rod 36 is slidably disposed in the limit groove 203.

[0015] By adopting the above technical solution, the auxiliary rod 35 and the movable rod 36 can provide auxiliary support for the connecting plate 37.

[0016] A filter frame 4 is fixedly installed on one side of the fixed frame 1. A water pump 42 is installed on one side of the filter frame 4. A water pump pipe 43 is fixedly installed on one side of the water pump 42. The water pump pipe 43 is fixedly inserted into the filter frame 4. A drain pipe 44 is fixedly installed on one side of the water pump 42. One end of the drain pipe 44 is fixedly installed in the water collection pipe 11.

By pouring zinc-containing industrial wastewater into the filter frame 4, the screen inside the frame 41 can initially screen out the wastewater to remove suspended solids, colloids or organic impurities, thereby reducing membrane fouling. By pulling the insert rod 46, the ring 47 slides inside the sleeve 45 and squeezes the spring 48, causing the insert rod 46 to disengage from the slot 411. This allows the frame 41 to be disassembled for centralized treatment of filtered impurities, preventing the screen from becoming clogged.

[0018] Working principle: First, zinc-containing industrial wastewater is poured into the filter frame 4, and the screen in the frame 41 performs preliminary screening of the wastewater to remove suspended solids, colloids or organic impurities, thereby reducing membrane fouling. The aeration pipe 22 is connected through an external pipeline, and gas is then supplied to the aeration pipe 22. The gas is then transported from the delivery pipe 23 and discharged from the outlet 26 in the outlet pipe 25. By turning on the motor 3, the bidirectional lead screw 31 rotates, causing the threaded block 32 to slide in the bearing plate 2 and move the moving rod 33. At the same time, the vertical plate 34 moves the connecting plate 37, causing the limiting plate 38 to move the fixed frame 24 and the outlet pipe 25. Thus, when aerating the hollow fiber membrane 12 to alleviate membrane fouling, the hollow fiber membrane 12 can be thoroughly cleaned, improving the cleaning effect. By pulling the insert rod 46, the ring 47 slides inside the sleeve 45, compresses the spring 48, and disengages the insert rod 46 from the slot 411, thereby enabling the frame 41 to be disassembled for centralized processing of filtered impurities and to prevent the screen from becoming clogged.
