Embodiment Construction

[0024] In order to better understand the technical solution of the present invention, it will be further described below in conjunction with specific embodiments:

[0025] like figure 1 As shown, the implementation of the present invention provides a TPU thin-walled hose for oxygenated aeration. Its main material is TPU polyurethane, adding a variety of additives to increase strength, elasticity and toughness, made by extrusion equipment such as figure 1 As shown in the thin-walled hose, the thickness of the pipe wall 2 is 0.1-1mm. In the non-oxygenated state, the openings 3 on the pipe wall are evenly made on the pipe wall 2 along the direction of the pipe centerline 1. The number of openings 3 on the TPU thin-walled hose per meter is 2000~8000, and the pipe wall 2 The shape of the upper opening 3 is long strip, the width is 0.05~0.25mm, and the length is 0.5~2.5mm. The tube centerline 1 is symmetrical on both sides. Under the condition of moderate stretching, the effect a...

Abstract

The invention provides a TPU thin-walled hose for oxygenic aeration and an opening mode. A main material adopts TPU polyurethane; meanwhile, a variety of additives are added to increase the strength, the elasticity, and the toughness; the wall thickness is 0.1-1 mm, the hose diameter is 25-100 mm; the quantity of openings per meter is 2000-8000, each of the openings in a hose wall is long strip-shaped and has a width of 0.05-0.25 mm and a length of 0.5-2.5 mm; the opening direction and the horizontal direction of a hose centerline form an included angle of 0-90 degrees, and the opening direction is symmetrical about the two sides of the hose centerline. The TPU thin-walled hose for the oxygenic aeration and the opening mode, provided by the invention, have the benefits that not only the effects of corrosion resistance, clogging resistance, uniform air distribution and high oxygen transfer efficiency, but also the effects of less resistance loss and greater ventilation capacity are achieved.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a TPU thin-walled hose for oxygenation and aeration and an opening method, belonging to the technical field of water treatment. Background technique [0002] At present, there are many kinds of oxygenation and aeration equipment used in the field of sewage treatment, and the materials are different, including PVC, ABS, rubber, carbon steel and stainless steel. Uniformity, or low oxygen transfer efficiency, there are always some unavoidable drawbacks. [0003] The aeration equipment made of similar polymer materials also has a large resistance loss and low ventilation due to factors such as wall thickness and opening method. Contents of the invention [0004] The purpose of the present invention is to provide a TPU thin-walled hose and opening method for oxygen-filled aeration to solve various problems in the above-mentioned traditional aeration equipment, not only to achieve corro...
