Abstract
The utility model relates to a microporous aeration device, which is characterized in that the microporous aeration device forms a pipe or a disk shape, wherein an installation opening is arranged on a pipe body or a disk body. When the utility model is used, the diameter of an air outlet split of the microporous aeration device is fixed and can not be influenced by the size of wind pressure. When the air outlet is clogged by dirt, the utility model is easy to be cleaned and the performance of the utility model can recover rapidly. Simultaneously, the utility model has the advantages of low manufacture cost and convenient installation.
Description
Technical field:
The utility model relates to the technical field of aerating apparatus, specifically a kind of microporous aeration device.
Background technology:
Aeration is by several forms such as jet-flow aeration, Inka aeration, micro-pore aerations at present, wherein the micro-pore aeration technology has very big development in recent years, and it is even with its gas distribution, the oxygen transfer efficiency height, easy for installation, advantage simple to operate is used widely in many fields such as chemical and medicine industry, printing and dyeing, food, papermaking.
The core component of micro-pore aeration technology is a micropore aeration pipe, is made up of rubber diaphragm, skeleton gas distribution pipeline.On the rubber diaphragm by very intensive fine cracks, during work, micropore aeration pipe etc. are placed on the air of sending certain blast in the water by gas distribution pipeline here, cause the rubber diaphragm bulging, fine cracks on the rubber diaphragm is become small gap by bulging, air is escaped from small gap, forms micro-bubble in water, rises slowly, oxygen in the process that rises in the bubble is dissolved in the water, breach is more little, and bubble is also more little, and the meltage of oxygen is also big more.
In actual application, with the micropore aeration pipe that rubber diaphragm is made, following phenomenon has appearred:
1, in the long term operation, the inwall of rubber diaphragm is stain by the air micronic dust gradually, thereby stops up; Crackle on the film makes the air output of micropore aeration pipe more and more littler, and the contamination that is attached to the rubber diaphragm inwall has no idea to remove.
2, rubber diaphragm is easy to wear out in the sewage that contains oils and organic solution, and working life is short.
3, the work characteristics of micropore aeration pipe is: after rubber diaphragm was subjected to the effect of blast, original crackle became breach, the blast height, and the breach diameter of formation is big, and the bubble diameter of effusion is big.Air pocket has following shortcoming: lift velocity is fast in water; Bubble is big more, and specific surface area is more little, and specific surface area is more little and lift velocity is fast, and the quantity that is dissolved into water oxygen is just few.If adopt little blast, breach is little, and the effusion bubble is also little, and lift velocity is slow, and specific surface area is big, and the meltage of oxygen rises, but blast one is little, and the number of bubbles of effusion significantly reduces, and the amount of giving altogether of oxygen has been lacked again.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved microporous aeration device, and it can overcome the difficult some shortcomings of removing of the contamination that is subjected to blast size variation, air outlet in the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of microporous aeration device is characterized in that: described microporous aeration device in a tubular form or plate-like, body or disk body are provided with an installing port.
The diameter of the breach of giving vent to anger of microporous aeration device of the present utility model is a fixed during use, can not be subjected to the influence of blast size, after the air outlet is stopped up by dirt, be easy to clean, soon can restorability, the utility model cost of manufacture is lower, easy for installation simultaneously.
Description of drawings:
Fig. 1 is the structural representation of the utility model one embodiment
Fig. 2 is the another structural representation of the utility model one embodiment
Fig. 3 is the structural representation of the utility model two embodiment
Fig. 4 is the structural representation of the utility model three embodiment
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model difference with the prior art is: described microporous aeration device in a tubular form or plate-like, body or disk body are provided with an installing port 1, wherein the piped microporous aeration device is pipe or oblate pipe, and body or disk body are made by the ceramic capillary material, and installing port is provided with installs screw thread 2.
In force the ceramic capillary material is sintered directly into oblateness, tubular or dish type, the installation screw thread of interface and the tubing threads engaged of plumbing during installation, get final product direct being connected with inlet pipe of aerating apparatus.
In application, stop up,, drop into burn for some time in the fire (about 10 seconds) and can recover its serviceability, just reinstall and to come into operation once more after the water flushing as long as aerating apparatus is dismantled down from intake ducting as finding that the micro-pore aeration pipe unit produces.
Claims (3)
1, a kind of microporous aeration device is characterized in that: described microporous aeration device in a tubular form or plate-like, body or disk body are provided with an installing port.
2, a kind of microporous aeration device according to claim 1 is characterized in that: the piped microporous aeration device is pipe or oblate pipe.
