Abstract
The present invention discloses a low aeration resistance disc type aerator, which comprises an upper cover, a base, a support frame and a rubber membrane, wherein the support frame is arranged between the upper cover and the base, the rubber membrane is arranged between the upper cover and the support frame, the rubber membrane is provided with a plurality of opening holes, each opening hole on the rubber membrane comprises three straight line holes, and the three straight line holes are connected through a center point. According to the present invention, with the trinacriform hole-shaped opening holes, mechanical properties of the rubber membrane are changed so as to provide good resilience, such that gas resistance loss can be reduced, can be controlled to less than 2000 Pa, and is far less than the national standard of less than 3500 Pa; and a flow rate of bubbles entering a water body is gentle so as to prolong a contact time of the bubbles and the water body, and increase oxygen utilization and oxygenation capacity.
Description
Technical field
The present invention relates to a kind of plate-type aerator, relate in particular to a kind of plate-type aerator that changes the rubber diaphragm hole shape and reduce aeration resistance that utilizes.
Background technology
Aerator is one of requisite equipment in municipal sewage plant, and is directly connected to processing benefit and the operation conditions of sewage work.At present, China municipal sewage plant adopts plate-type aerator to carry out the biochemical aeration oxygenation mostly, and along with the quick construction of each municipal sewage plant of China, the market demand of plate-type aerator is also increasing.
In order to guarantee the normal operation of sewage work, improve treatment efficiency, reduce running cost, the technical feature of aerator is had higher requirement.Traditional plate-type aerator, on its rubber diaphragm perforate be shaped as " one " font, be single linear perforate, gas is during by the perforate of " one " word, need overcome larger rubber diaphragm elastic force could strut the perforate of " one " word, and air resistance loss nature increases; And rubber diaphragm deformation power is larger, easily causes rubber diaphragm to tear at the two ends of " one " word perforate and damaged.
Summary of the invention
Purpose of the present invention provides a kind of plate-type aerator that changes the rubber diaphragm hole shape and reduce aeration resistance that utilizes with regard to being in order to address the above problem.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes loam cake, base, bracing frame and rubber diaphragm, support frame as described above is arranged between described loam cake and the described base, and described rubber diaphragm is arranged between described loam cake and the support frame as described above, is provided with a plurality of perforates on the described rubber diaphragm; The described perforate of on the described rubber diaphragm each comprises three straight holes, and described three straight holes connect by a central point.
The perforate of above-mentioned trident hole shape has changed the mechanical property of rubber diaphragm, makes it to have preferably rebound resilience, thereby has reduced the drag losses of gas, can be controlled at below the 2000Pa, far below the requirement below the GB 3500Pa.
As preferably, described three straight holes be uniformly distributed in a described central point around.
Further, described perforate comprises many rows, and the orientation of the described perforate of adjacent two rows is opposite.
Beneficial effect of the present invention is:
The present invention utilizes the perforate of the trident hole shape of rubber diaphragm to change its mechanical property, makes it to have preferably rebound resilience, thereby has reduced the drag losses of gas, has improved working efficiency; The perforate of the trident hole shape of rubber diaphragm also so that the air bubble flow rate that process the present invention enters in the water body is milder, has prolonged the duration of contact of bubble and water body, has improved utilization ratio and the oxygenation capacity of oxygen.

Fig. 1 is broken section structural representation of the present invention;
Fig. 2 is the open-celled structure schematic diagram of rubber diaphragm among the present invention;
Fig. 3 is the open-celled structure schematic diagram of rubber diaphragm in traditional aerator.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, the present invention includes loam cake 1, base 6, bracing frame 5 and rubber diaphragm 4, bracing frame 5 is arranged between loam cake 1 and the base 6, and rubber diaphragm 4 is arranged between loam cake 1 and the bracing frame 5, is provided with a plurality of perforates 7 on the rubber diaphragm 4; Each perforate 7 on the rubber diaphragm 4 comprises three straight holes, and described three straight holes connect by central point, described three straight holes be uniformly distributed in a described central point around; Perforate 7 comprises many rows, and the orientation of adjacent two rows of openings 7 is opposite.2 is the O shape rubber ring at rubber diaphragm 4 edges among Fig. 1, and 3 is the pore on the bracing frame 5.
As shown in Figure 2, the present invention utilizes the perforate 7 of the trident hole shape of rubber diaphragm 4 to change its mechanical property, makes it to have preferably rebound resilience, thereby has reduced the drag losses of gas, has improved working efficiency; The perforate 7 of the trident hole shape of rubber diaphragm 4 also so that the air bubble flow rate that process the present invention enters in the water body is milder, has prolonged the duration of contact of bubble and water body, has improved utilization ratio and the oxygenation capacity of oxygen.
As shown in Figure 3, the perforate 8 of rubber diaphragm 4 is the perforate of single rectilinear " one " word in traditional aerator, and when gas passed through the perforate 8 of " one " word, the elastic force that need overcome larger rubber diaphragm 4 could strut " one " word perforate 8, and air resistance loss nature increases; And rubber diaphragm 4 deformation power are larger, easily cause rubber diaphragm 4 to tear at the two ends of " one " word perforate 8 and damaged.
