Technical Field
[0001] The utility model relates to a device for quickly disassembling a DTRO membrane shell and a central pull rod, and relates to the technical field of high-concentration sewage treatment. Background Art
[0002] DTRO membrane process technology has been widely used in high-concentration sewage treatment, among which DTRO membrane components are the core process equipment. Since DTRO membrane components adopt disc-tube membrane column structure, they have more spacious fluid channels, making them resistant to high pressure and fouling. Even in high-salt and high-COD conditions, they can operate stably and economically. With the increasing use of DTRO membrane components, the amount of disassembly and maintenance of membrane components during project operation and maintenance is also not small. Since the components of DTRO membrane components are tightly sealed, if the membrane shell and guide plate are disassembled manually, it will take a lot of manpower and time, and there is a risk of injury, and the work efficiency is low.
[0003] Therefore, it is necessary to study a device for quickly disassembling the DTRO membrane shell and the central pull rod, reduce the labor intensity of personnel, shorten the working time, and improve the efficiency and safety of membrane assembly disassembly. After special design, the utility model provides a device for quickly disassembling the DTRO membrane shell and the central pull rod. Summary of the invention

[0006] A device for quickly disassembling a DTRO membrane shell and a center pull rod comprises an electric hoist, a wired controller, a fastening nut, a membrane shell limiting component, a center pull rod limiting component, a DTRO membrane assembly, and a carbon steel frame. The electric hoist is installed on a hanging hole under an I-beam at the top of the carbon steel frame. The membrane shell limiting component and the center pull rod limiting component are fixed to the carbon steel frame by welding. The wired controller is used to control the lifting and lowering of the electric hoist hook.
[0007] in:
[0008] 1. The electric hoist adopts a ring chain type, and the wired controller meets the requirements of waterproof and dustproof, with a rated lifting capacity of 5000kg;
[0009] 2. The membrane shell limiter is formed by welding a carbon steel plate with a round hole and a square steel. The diameter of the round hole is 209mm.
[0010] 3. The center pull rod limiter is welded from a carbon steel plate with a thickness of 10 to 20 mm;
[0011] 4. The DTRO membrane module is a standard 75 kg or 90 kg membrane module, which is the object of disassembly;
[0012] 5. The carbon steel frame is assembled and welded by I-beams, square steels, angle steels, galvanized pipes and other materials to form an integral carbon steel frame structure with an operating platform, ladders and railings.
[0013] The beneficial effects of the utility model are:
[0014] 1. Using the power of electric hoists to replace manpower greatly reduces the labor intensity of personnel and significantly shortens the time consumption.
[0015] 2.

[0022] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods.
[0023] The utility model provides a device for quickly disassembling the DTRO membrane shell and the central pull rod, such as Figure 1 Main view, Figure 2 Left view, Figure 3 As shown in the top view, the disassembly device includes an electric hoist 1, a wired controller 2, a fastening nut 3, a carbon steel frame 4, a central pull rod 5, a DTRO membrane assembly 6, a membrane shell 7, a membrane shell limiting component 8, and a central pull rod limiting component 9.
[0024] The electric hoist 1 is installed on the lifting hole under the I-beam at the top of the carbon steel frame 4, and the lifting and lowering of the hook on the electric hoist 1 is controlled by the wired controller 2. When disassembling the membrane shell 7 of the DTRO membrane assembly 6, first tighten the fastening nut 3 to the upper part of the central tie rod 5 of the DTRO membrane assembly 6 by a wrench, and then manually place the DTRO membrane assembly 6 to be disassembled vertically in the membrane shell limiting component 8, and the hook of the electric hoist 1 is hooked on the fastening nut 3 on the upper part of the central tie rod 5. The hook on the electric hoist 1 is controlled to rise slowly by the wired controller 2, and at the same time, the axis of the central tie rod 5 is ensured to pass through the center of the circle of the upper circular hole of the membrane shell limiting component 8. In the process of lifting the central tie rod 5, the membrane shell 7 will not move upward due to the blocking effect of the membrane shell limiting component 8. Only the central tie rod 5 inside the membrane shell 7 with the guide plate will be separated from the DTRO membrane assembly 6 as the hook rises, thereby realizing the rapid removal of the membrane shell 7.
[0025] Next, when disassembling the center tie rod 5, the DTRO membrane assembly 6 after the membrane shell 7 is removed is manually placed vertically in the center tie rod limiting component 9, and the hook of the electric hoist 1 is hung on the fastening nut 3 on the upper part of the center tie rod 5. The hook on the electric hoist 1 is controlled to rise slowly through the wired controller 2, and at the same time, it is ensured that the axis of the center tie rod 5 passes through the longitudinal center line of the upper hole of the center tie rod limiting component 9. In the process of lifting the center tie rod 5, the guide plate on the center tie rod 5 will not move upward due to the blocking effect of the center tie rod limiting component 9. Only when the center tie rod 5 is separated from the DTRO membrane assembly 6 as the hook rises, the guide plate is scattered to the ground. In summary, the disassembly process of the membrane shell 7 and the center tie rod 5 is completed quickly.
[0026] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modifications and changes made according to the present invention shall fall within the protection scope of the present invention.
