Defects such as poor efficiency, insufficient oxygen supply, and high mechanical failure rate; it is a multi-purpose slat type microporous aerator. Ben The invented slat-type microporous aerator has been innovative in five areas:

1. The multi-purpose slat type microporous aerator of the invention adopts the form of a slat-type wide-faced strip, and the length can be 6000 mm to 10000 mm, and the width can be 200 mm to 600 mm, which can greatly improve the service area and reduce exposure. The air dead zone reduces the disadvantages of connectors and air leaks.

2. The multi-purpose slat type microporous aerator of the present invention ingeniously sets a flat square air passage under the curved plate of the curved slat, so that the aerator itself is disposed between the gaps by using its structural features Air passage. The air distribution channel can also be arranged in a plurality of sizes or different shapes as needed.

3. The curved slat of the multi-purpose strip-shaped microporous aerator of the present invention is provided with a curved V-shaped card slot on both sides, and the upper opening of the V-shaped card slot is provided with a bump to prevent the sealing strip from being deflated And leaking.

5. The multi-purpose slat type microporous aerator of the present invention is provided with a non-resistance check valve every 400 to 600 mm length, so that the air distribution is uniform between one length and the sewage can be prevented from being poured back into the water. In the gas pipeline, the ventilation is affected, and the microporous aerator can be used for gap aeration to meet the operation requirements of various processes and achieve energy saving. When there is no resistance, the check valve is lifted up, so that a gap is formed between the valve originally covering the curved plate and the curved plate, and the air enters between the curved plate and the rubber aeration diaphragm through the gap, and then passes through the rubber. The aeration hole on the aeration membrane achieves aeration; when the gas is stopped, the non-resistance check valve falls back and the seal covers the curved plate; this non-resistance design does not increase the resistance of the check valve opening, achieving high efficiency The common purpose of energy-saving operation.
