[0006] 4 The tower type structure that split frame connects is located in the inside of sleeve, and there is a gap between split frame and the inner wall of sleeve, the upper end surface of gap is blocked, and the lower end surface is open.

[0007] Further, the lower end of each split frame extends inwardly and horizontally to provide a maintenance platform, the inner edge of the maintenance platform is provided with a handrail, and a ladder is installed between adjacent upper and lower maintenance platforms.

[0008] Further, the handrail and the ladder are of detachable structure.

[0009] Compared with the prior art, the utility model has the advantages of:

[0010] 1. The utility model discloses a whole three-dimensional conical membrane is changed into the split frame type three-dimensional membrane, and the whole frame is composed of four layers after the transformation, and each layer has 12 separate membrane blocks, which is convenient for daily cleaning and maintenance while ensuring the same filtering area as the original membrane block.

[0011] 2. The filter membrane module has only one size, and has strong interchangeability, reduces the storage quantity of spare parts, and saves the occupied capital of spare parts inventory.

[0012] 3. The utility model discloses a maintenance platform and detachable ladder in each layer split frame, which is convenient for personnel maintenance. DRAWINGS
