Abstract
Description
Technical Field
[0001] This utility model relates to the field of MBR membrane lifting technology, and in particular to an MBR membrane lifting device. Background Technology
[0002] After a period of use, MBR flat-sheet membranes accumulate dirt and impurities on their surface, or may experience damage or aging inside the membrane modules, necessitating offline cleaning or maintenance. Furthermore, when the membrane modules reach their designed lifespan, they must be lifted and replaced to ensure normal system operation and effluent quality. Traditionally, these operations require lowering the water level in the membrane tank to allow workers to enter. However, this process poses significant safety hazards. Workers must descend to the bottom of the tank to attach hooks to the lifting points on the membrane modules, demanding not only advanced operational skills but also the ability to work at heights and in confined spaces. Therefore, this traditional method is not only cumbersome but also highly dangerous, posing a significant threat to worker safety. Utility Model Content
[0003] This utility model solves the problems in related technologies and proposes an MBR membrane lifting device. The MBR membrane module is lifted by the cooperation of the guide groove and guide rod on the lifting frame, and the lifting ring on the lifting frame cooperates with the back-mounted lifting lug. When lifting, the rope is tied at the rope point. After the MBR membrane module is placed at the bottom of the tank, the ropes tied on both sides are pulled up, and the lifting ring can be released. The operation is simple and does not require manual entry into the bottom of the tank, which greatly reduces the danger.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an MBR membrane lifting device, including a lifting frame and an MBR membrane module, wherein the lifting frame is provided with first guide grooves on both sides, the lifting frame is provided with lifting rings and the lifting rings are provided with rope tying points, the MBR membrane module is provided with guide rods adapted to the first guide grooves on both sides, and the top of the MBR membrane module is provided with a sloping back type lifting lug adapted to the position of the lifting rings, and the lifting frame slides down along the guide rods through the first guide grooves so that the lifting rings hook to the center of the sloping back type lifting lugs by their own weight.
[0005] As a preferred embodiment, the lifting frame is an I-shaped structure, including a crossbar and longitudinal bars disposed at both ends of the crossbar.
[0006] As a preferred embodiment, both ends of the two longitudinal rods are equipped with lifting rings.
[0007] As a preferred embodiment, the sloping-back lifting lug includes a first surface, a second surface, and a groove. The first surface is a horizontal surface and is mounted on the MBR membrane module. The second surface is an arc-shaped surface so that the lifting ring can hook onto the groove.
[0008] As a preferred embodiment, the MBR membrane module is provided with second guide grooves on both sides, and the guide rod is limited by the second guide grooves.
[0009] As a preferred embodiment, the upper part of the guide rod is fixed to the inner wall of the pool via a fixing rod.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses the guide groove and guide rod on the lifting frame to cooperate, and the lifting ring on the lifting frame cooperates with the back-mounted lifting lug to lift the MBR membrane module. When lifting, by tying ropes at the rope points, after the MBR membrane module is placed at the bottom of the tank, the ropes tied on both sides are pulled up, and the lifting ring can be released. The operation is simple, and no manual entry into the bottom of the tank is required, which greatly reduces the danger. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0021] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0022] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.
