Tubular membrane sheet pore membrane aerator

Abstract

The invention provides a tubular membrane sheet pore membrane aerator, which comprises a liner pipe, wherein a first connector similar to a cylinder is inserted into one end of the liner pipe, a through hole is formed in the first connector along the axial direction, a baffle is arranged in the middle of the through hole, the first connector is provided with a plurality of vent holes in the side,away from the liner pipe, of the baffle, internal threads are arranged at the end portion, on the same side as the vent hole, of the vent hole, the first connector is provided with a clamping block for connecting with a wrench in a clamped, the clamping block is provided with a plurality of clamping grooves penetrating in the axial direction of the first connector, the first connector is also provided with a first positioning ring and a check ring, a second connector similar to a cylinder is inserted into one end, far away from the first connector, of the liner pipe, is provided with a secondpositioning ring, and is provided with an end cover, the end cover is provided with a plurality of water discharge holes formed in the axial direction of the end cover, the liner pipe is sleeved witha tubular membrane sheet, the membrane sheet is provided with a plurality of aeration holes, and clamping hoops for fixing the membrane sheet, the first connector and the second connector are arrangedat the positions, corresponding to the first positioning ring and the second positioning ring, outside the membrane sheet. The tubular membrane sheet pore membrane aerator of the invention has advantages of good air tightness and the like.

Description

technical field [0001] The invention relates to the technical field of aerators, in particular to a tubular membrane aerator with holes. Background technique [0002] In the field of sewage treatment, the aerator has a great influence on the oxygen transfer efficiency and the operating cost of sewage treatment. The domestic development and application of aerators began in the mid-1980s, and the representative ones are: perforated tube aeration, corundum aerator, disc microporous aerator, tubular diaphragm hole membrane aerator, jet flow aerator, etc. Aerators, diffuse flow aerators, cyclone aerators, etc. [0003] Though wherein existing aerator can carry out conventional aeration, there are still many deficiencies: [0004] 1. Insufficient air tightness, there are phenomena of air leakage and muddy water backflow; [0005] 2. The engineering installation is inconvenient and the product reliability is poor; [0006] 3. The diaphragm is easily damaged and the product life...
