Description

Hanging multi-tube microporous aerator

technical field

The utility model relates to sewage biochemical treatment equipment, in particular to a suspended multi-pipe microporous aerator.

Background technique

The aerator is mainly used in the oxygenation and aeration in the newly built and renovated water treatment projects of urban domestic sewage and various industrial wastewater. Aeration is the most important system in the overall water treatment project, and other facilities basically revolve around aeration. The system is built, so the quality of aeration will directly affect the water outlet effect. The aeration equipment currently used mainly includes rotary butterfly aerators, disc aerators, etc., which have the disadvantages of low oxygen utilization rate, low oxygenation power efficiency, complex structure and high manufacturing and operating costs.

Contents of the invention

The purpose of the utility model is to provide a suspended multi-tube microporous aerator with convenient installation and maintenance, uniform aeration, no need for air purification and moderate price.

The technical scheme that the utility model adopts is:

Suspension multi-pipe microporous aerator, including intake branch pipe, intake flexible branch pipe, support pipe, air distributor and rubber membrane sleeve, one end of the two intake flexible branch pipes is connected with the intake branch pipe through a tee, The rubber membrane sleeve is set on the support tube, and the two ends of the support tube are fixed by the rubber membrane sleeve. The air flow distributor end of the rubber membrane sleeve is provided with self-closing micropores. The at least two support tubes are left and right It is connected and fixed on the gas path communication pipe, the other end of the air intake flexible branch pipe is connected with the gas path communication pipe, and the turning points of the two intake flexible branch pipes are respectively sleeved with counterweights.

The number of the support pipes is 2-16, and the left and right connections are fixed on the gas passage communication pipes.

The micropores of the membrane sleeve are arranged in a quincunx shape.

The hanging ring is fixed on the gas path communication pipe.

The utility model adopts the two ends of the air intake soft branch pipe and multi-point air intake in the gas path intercommunication pipe, and the number of multiple support pipes and rubber membrane sleeves is 2 to 16, so that the aeration is uniform. Due to the addition of counterweights at the turning points of the flexible intake pipes, the aerator can be submerged in water. During the operation of the aerator, due to the different aeration sequences of the left and right rubber membrane sleeves of the gas path interconnection pipe, the aerator The weight of the left and right sides of the road interconnection pipe is different, so that the aerator swings from side to side, which can reduce the sludge deposition at the bottom of the pool, reduce the dead zone phenomenon, increase the aeration area, and improve the oxygenation capacity. The end of the air distributor of the rubber membrane sleeve of the present invention has self-closing micropores arranged in the shape of plum blossoms, so that the micropores are not easy to break, and at the same time, sewage backflow and blockage are avoided. The hanging ring is fixed on the gas path communication pipe, so that the aerator can be lifted freely, and the maintenance is safer and more convenient.

The utility model has the following advantages:

1. Uniform aeration, small bubbles, high oxygen utilization rate and high power efficiency.

2. It has good flow velocity and flow state, small resistance and low energy consumption.

3. No need to purify air, no backwash, no vent valve, more convenient management.

4. Easy to install. It can be installed with or without water in the pool. No configuration is required in the pool. If maintenance is required for long-term aeration, it can be lifted freely for maintenance, no need to drain water, no need to shut down the fan, and normal operation will not be affected.

5. The micropores are arranged in a plum blossom shape, which is not easy to break, and the self-closing micropores avoid sewage backflow.

Six, the price is moderate.
