Problems solved by technology

Since the micro-holes on the rubber disc diaphragm used are punched by mechanical needles, this brings two disadvantages. One is that there are burrs around the micro-holes formed. It is torn or fails during the opening and closing process, which will eventually lead to shortened life of the disc aerator diaphragm, increased resistance, and reduced oxygen utilization rate; the second is that the number of micropores is large, and the processing is troublesome and time-consuming

Embodiment 1

[0019] Example 1. See Fig. 1, the perforating device of this example has a steel disc base 1, and the center of the base has a fixed shaft 3, and the shaft is provided with a middle slot 4 passing through the fixed shaft. The cutter belt 2 is made of alloy steel, and its specifications are: length×width×thickness=14500mm×25mm×1.5mm. There are continuous ladder-shaped cutter heads on the cutter belt (see Fig. 2 and Fig. 3), and the thickness of the cutter head is 0.5 mm. mm, the tooth height of the cutter head is 5mm (equal to the thickness of the processed aeration diaphragm), evenly distributed, and the blade is in the shape of a line. With the cutter head 6 facing upwards, the head end of the cutter belt 2 is embedded in the middle slot 4 of the fixed shaft, and then tightly coiled on the fixed shaft. After reaching the designed diameter, the end of the cutter belt 2 is welded on the outer ring 5 . An outer ring 5 with an internal diameter of 270mm is welded to the disc bas...

Embodiment 2

[0021] Example 2. The distance between the cutter heads gradually increases from the outside to the inside, so that the inner and outer layers of the micropores of the aerator membrane are relatively uniform. The rest are the same as example 1.

Abstract

This invention relates to a kind of disc type aerator jockey opening pore device. This invention improves efficiency of opening pore, and micropore shape is neat, can prolong service life of jockey and aerator. This opening pore device has one bedplate(1), at the centre of bedplate has fixed axis(3); head end of cutter strap(2) fix with fixed axis, and coiled coil on the fixed axis; fringe of cutter strap(2) has several of series knife head(6), and knife head thickness is less than cutter strap thickness; outer ring(5) is tightly lock cutter strap(2), and fix with bedplate(1).

Description

technical field [0001] The invention relates to a device for opening holes in a diaphragm of a disc aerator, which is suitable for processing disc microporous rubber aeration membranes used in sewage treatment projects. Background technique [0002] At present, one of the leading sewage treatment processes used in engineering - SBR process, has the characteristics of intermittent operation and frequent opening and closing times. Since the micro-holes on the rubber disc diaphragm used are punched by mechanical needles, this brings two disadvantages. One is that there are burrs around the micro-holes formed. It is torn or fails during the opening and closing process, which eventually leads to shortened life of the disc aerator diaphragm, increased resistance, and reduced oxygen utilization rate; second, the number of micropores is large, and processing is troublesome and time-consuming. Contents of the invention [0003] The oxygen transfer efficiency and life of the aerato...
