Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, and in particular to a membrane module for deep treatment of coal coking wastewater. Background Technology

[0002] Coking plants generate a large amount of wastewater during the coking process. Currently, coking plants generally use wastewater treatment membranes for auxiliary treatment to facilitate deep treatment of wastewater. However, existing wastewater treatment membrane modules still have room for improvement in coking wastewater treatment. For example, due to the complex composition of coking wastewater, existing membrane modules are prone to rapid wear and tear. This necessitates timely removal and maintenance of the membrane modules using hoisting equipment. However, the complex fixing methods of existing membrane modules make disassembly and assembly cumbersome, thus affecting efficiency. To address these issues, this application proposes a deep treatment membrane module for coal coking wastewater to solve the aforementioned problems. Utility Model Content

[0003] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides a membrane module for deep treatment of coal coking wastewater. The technical solution it provides includes a treatment tank. The treatment tank contains a support frame, with a support leg fixedly connected to the bottom of the support frame and abutting against the bottom of the treatment tank. Multiple sets of horizontally evenly distributed mounting frames are fixedly connected within the support frame, each mounting frame having an MBR membrane fixedly connected to it. An aeration device is arranged at the bottom of the support frame. Two opposing suspension rods are fixedly connected to the upper end of the support frame, with a lifting lug fixedly connected to the upper end of each suspension rod. Longitudinal movement inserts are arranged at both the front and rear ends of the treatment tank, with each longitudinal movement insert fixedly connected to a rod, and the rods and lifting lugs are inserted one-to-one.

[0004] Each of the longitudinal moving plugs includes two longitudinal rods fixedly connected to the processing box. The two longitudinal rods are fixedly connected to a crossbeam. The crossbeam and the opposite end of the mounting box are rotatably connected to a drive screw. The drive screw is threadedly connected to the middle of the longitudinal moving rod. The left and right ends of the longitudinal moving rod are slidably connected to the two longitudinal rods respectively. The longitudinal moving rod is fixedly connected to the plug rod.

[0005] Preferably, the aeration device includes a U-shaped aeration pipe arranged below the support frame, the aeration pipe having several evenly distributed aeration holes, several clamps fixedly connected to the bottom of the treatment box, each clamp being fixedly connected to the aeration pipe, the inlet end of the aeration pipe being fixedly connected to an air inlet pipe, and the air inlet pipe extending forward out of the treatment box.

[0006] Preferably, the longitudinal moving rod is fixedly connected to a threaded sleeve that is fixedly connected to the drive screw in the middle, and the left and right ends of the longitudinal moving rod are respectively fixedly connected to sliding sleeves that are slidably connected to the longitudinal rods on their corresponding sides. The front end of the drive screw passes forward through the crossbeam and is coaxially fixedly connected to a handwheel.

[0007] The beneficial effects of this utility model are:

[0008] During use, the membrane module can perform deep filtration of coking wastewater through the MBR membrane, and the aeration device can further enhance the wastewater treatment effect. Furthermore, the longitudinal movement insert can be adjusted via a drive screw, allowing the insert to quickly move in and out of the lifting lugs. When hoisting and maintenance are required, the longitudinal movement insert quickly disengages the insert from the lifting lugs, allowing the support frame and MBR membrane components to be removed for maintenance. After maintenance, the support frame and MBR membrane components are hoisted back into the treatment tank, and the longitudinal movement insert is used again to reposition the insert into the lifting lugs for restraint. This quick operation ensures the efficient use of this application. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-6The specific embodiments of this utility model will be described in further detail.

[0018] In the first embodiment, the technical solution is that, during use, the membrane module can perform deep filtration of coking wastewater through the MBR membrane 4, and the aeration device 5 can improve the wastewater treatment effect. Furthermore, the longitudinal movement insert 8 can adjust the insertion rod 9 via the drive screw 12, allowing the insertion rod 9 to quickly move in and out of the lifting lug 7. When hoisting and maintenance are required, the longitudinal movement insert 8 drives the insertion rod 9 to quickly disengage from the lifting lug 7, allowing the support frame 2, along with the MBR membrane 4 and other components, to be removed and maintained. After maintenance, the support frame 2, along with the MBR membrane 4 and other components, is hoisted into the treatment tank 1, and the longitudinal movement insert 8 again drives the insertion rod 9 to insert into the lifting lug 7 fixedly connected to the lifting rod 6 for restraint. The operation is quick, ensuring the efficiency of the application.

[0019] In Example 2, based on Example 1, specifically, in use, a support frame 2 is arranged inside the treatment tank 1. The support frame 2 is connected to several evenly distributed MBR membranes 4 via mounting frames 3. The MBR membranes 4 can then treat coking wastewater. During treatment, an external blower connected to the air inlet pipe 17 can deliver gas to the aeration pipes 14 and aeration holes 15, causing the MBR membranes 4 to vibrate and ensuring their effectiveness. This allows for efficient and deep treatment of wastewater. The aeration holes 15 are fixed to the bottom of the treatment tank 1 by clamps 16, and the aeration pipes 14 are arranged in a U-shape to facilitate even aeration.

[0020] When the MBR membrane 4 malfunctions and requires maintenance, the drive screw 12, which is rotatably connected to the crossbeam 11, is rotated clockwise. A handwheel 20 is provided to facilitate the clockwise rotation of the drive screw 12. The clockwise rotation of the drive screw 12 drives the longitudinal shift rod 13 via the threaded sleeve 18. The longitudinal shift rod 13 is longitudinally slidably connected to the longitudinal rod 10 via the sliding sleeve 19. Therefore, the clockwise rotation of the drive screw 12 drives the longitudinal shift rod 13 to move outward along the longitudinal rod 10 and disengage from the lifting lug 7. Then, the external lifting equipment can be engaged with the lifting lug 7 for further operation. The hoisting operation is carried out to lift the support frame 2 together with the MBR membrane 4 and other components out of the treatment tank 1 for maintenance. After the maintenance is completed, the support frame 2 together with the MBR membrane 4 and other components are hoisted back into the treatment tank 1 and the lifting lugs are aligned with the insertion rod 9. Then, the drive screw 12 is rotated counterclockwise, which can drive the insertion rod 9 to move along the longitudinal rod 10 toward the lifting lug 7, so that the insertion rod 9 is inserted into the lifting lug 7, thereby confining the support frame 2 together with the MBR membrane 4 and other components in the treatment tank 1 for wastewater treatment.
