[0019] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme of the utility model will be described clearly and completely in combination with the drawings and a preferred embodiment.

[0020] Referring to Figures 1-3A membrane group installation device comprises a balance beam 1, a rectangular leg 2, an H-shaped lug 3, a positioning pin 4, a semicircular ring 5, an L-shaped leg 6, a lifting plate 7 and a round safety pin 8. The rectangular leg 2 and the L-shaped leg 6 constitute an installation assembly, and four installation assemblies form a membrane group installation support; the balance beam 1, the H-shaped lug 3 and the lifting plate 7 constitute a lifting assembly of the membrane group, and the positioning pin 4, the semicircular ring 5, a chain and the round safety pin 8 constitute a bolt assembly.

[0021] The balance beam 1 is a rectangular main frame formed by welding square tubes, and the lifting plate 7 is welded at the center of gravity of the balance beam 1. The lifting plate 7 is provided with a lifting hole. The balance beam 1 and the lifting plate 7 are welded to form a stable lifting point. When the membrane group is lifted, the hook on the lifting facility can be directly hooked on the lifting plate 7, and the lifting force is concentrated at one point, which is beneficial to the stable lifting and movement of the membrane group, thereby improving the lifting efficiency. The design of the single-point lifting structure can avoid the lifting form of the membrane group suspended by the hooks through the steel wire rope in multiple points, thereby reducing the occupied space of the steel wire rope, reducing the lifting height and saving the construction cost of the membrane workshop.

[0022] The H-shaped lug 3 is welded at the four corners of the balance beam 1. The H-shaped lug 3 can strengthen the strength of the balance beam and limit the rotation of the L-shaped leg 6. In the embodiment, the H-shaped lug 3 is made of an I-beam. The two wing plates of the I-beam are vertically welded on the outer side of the balance beam, and the web plate is horizontal. The positioning pin 4 is vertically welded on the upper side of the web plate. In the embodiment, the positioning pin is made of a round steel. The upper end of the round steel is provided with a radial through hole. The diameter of the radial through hole is matched with the round safety pin 8. The semicircular ring 5 is welded at the four corners of the balance beam 1. One end of the round safety pin 8 is connected with the semicircular ring 5 through a chain or a rope, and the other end is inserted into the positioning pin 4, which can effectively prevent the round safety pin 8 from being lost.

[0023] Two round holes are formed at the bottom of the rectangular leg 2. The hole spacing of the two round holes is consistent with the spacing of the connecting holes of the membrane group. The rectangular leg 2 and the L-shaped leg 6 are connected by welding to form a membrane group installation support. The L-shaped leg 6 is horizontally arranged, and the rectangular leg 2 is vertically arranged below the corner of the L-shaped leg 6. In the embodiment, the rectangular leg 2 is made of a channel steel. The two ends of the channel steel are welded with steel plates. The upper steel plate is used to connect the L-shaped leg 6, and the lower steel plate is used to connect the membrane group.

[0024] In the embodiment, the L-shaped leg 6 is made of a channel steel. The width of the channel steel is matched with the width between the two wing plates of the H-shaped lug 3. The two ends of the L-shaped leg 6 are respectively provided with a waist-shaped hole. One end of the waist-shaped hole is used to connect the balance beam 1, and the other end of the waist-shaped hole is used to connect the membrane pool. The waist-shaped hole has a certain adjustability, which is beneficial to the installation of the membrane group. Specifically, the channel steel is pre-buried in the side wall of the membrane pool, and the L-shaped leg 6 is tightly connected with the pre-buried channel steel through the bolt passing through the waist-shaped hole.

[0025] The design of the L-shaped legs 6 makes the width required for membrane module installation narrower, which is particularly suitable for scenarios where the existing MBR membrane tank is insufficient in width.

[0026] When connecting the L-shaped leg 6 and the balance beam 1, one end of the L-shaped leg 6 is placed in the H-shaped ear 3, and the waist-shaped hole on the L-shaped leg 6 passes through the positioning pin 4, and then the round safety pin 8 is inserted into the through hole of the positioning pin 4 to prevent it from falling off. Through this connection method, the amount of on-site disassembly and assembly work caused by the use of bolts and nuts can be reduced, making installation faster and more efficient.

[0027] In installation mode, the framework structure consisting of the mounting assembly and the hoisting assembly secures a membrane module within the MBR membrane tank. The shape and size of the membrane module are adapted to the mounting device. Specifically, when installing the membrane module, bolts are used to connect the rectangular legs 2 to the membrane module. Then, circular safety pins 8 are used to connect the L-shaped legs 6 to the balance beam 1. The membrane module is then suspended and installed within the MBR membrane tank by hooking the hoisting plate 7 directly onto the balance beam 1. Finally, the other end of the L-shaped legs 6 is bolted to the pre-buried channel steel in the membrane tank to secure the membrane module in place.

[0028] During the installation of the membrane module, since the balance beam 1 adopts a split design, the balance beam 1 of the membrane module can be disassembled after the installation of a single set of membrane modules, and used for the one-by-one lifting of other membrane modules. Compared with the membrane module installation device with an integrated structure, the split design of the balance beam 1 and the membrane module installation bracket can reduce the amount of profiles used and save installation costs.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also within the scope of protection of the present invention.
