Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing:

[0017] Such as figure 1 , 2 As shown, the present invention is made up of connecting rod 1, aerator 2, fixed interface 3, check valve 4, air inlet interface 5 five parts. Each aeration sheet 2 is stacked through the connecting rod 1 , and the lower end of the connecting rod 1 is threadedly connected with the fixed interface 3 for fixing each aeration sheet 2 . The diameter of each aerator 2 increases successively to form a conical structure, such as conical, square, trapezoidal, and inverted conical, trapezoidal, etc. Among these shapes, conical is the most suitable because the conical air distribution is more uniform. The contact cross-sections between the aerators 2 are provided with a number of tiny slot-shaped air outlets 6 for air outlet. The diameter of the micro-groove air outlet 6 is within 0.1mm-1.5mm. The reason why it is limited to 0.1-1.5mm is: the diameter ...

Abstract

The invention discloses plastic sheet overlaid and mounted porous aeration equipment which is characterized by comprising a connection rod (1), wherein the connection rod (1) is provided with multiple aeration sheets (2); the diameters of the aeration sheets (2) are successively increased, and the aeration sheets (2) are overlaid to form a cone shape; a fixed interface (3) is installed on the lower end of the connection rod (1); and a gas inlet interface (5) is installed on the lower end of the fixed interface (3). The plastic sheet overlaid and mounted porous aeration equipment has the characteristics that the structure is compact and reasonable; the service life is long, and cleaning and exchange are not needed; service area is large, resistance is small, and operation is stable and reliable; adaptability is strong, the equipment is suitable for purification treatment of various sewages; and oxygen utilization rate is high, bubbles are uniform, and no dead angle is generated, thereby solving the problems generated by using the traditional aeration oxygenation equipment and having better aeration effect.

Description

technical field [0001] The invention relates to an aeration and oxygen-increasing equipment for an aeration tank, which is used for installing on an aeration pipeline to purify sewage, and belongs to the technical field of environmental protection equipment. Background technique [0002] Aeration devices have been used as sewage treatment technology for a long time. At present, they are widely used in sewage treatment processes such as contact oxidation method and activated sludge method, such as corundum aerators and rubber aerators. However, the biggest disadvantages of these aeration and oxygenation equipment are large resistance loss, easy to block, easy to age, low oxygen utilization rate, poor adaptability, easy to produce dead angle, uneven bubbles, etc., and the maintenance is very inconvenient, which affects aeration The dissolved oxygen effect of the pool. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned d...
