In the water treatment aerobic process, often adopt micro-hole aerator, to satisfy the demand of aerobic process to oxygen to the oxygen supply of water kind.Micro-hole aerator, according to hole state of nature form, be divided into two big classes, one class is that aeration is opened the hole, the microporous diaphragm aerator of the closed pore that stops exposing to the sun, for example Chinese patent CN2644419 etc. is described, its main deficiency is: one owing to be to open the hole by air pressure, thereby aeration resistance is higher relatively, usually in the 3500-4200Pa scope; Two rubber diaphragms are easily aging, and corrosion-resistant problem, and it is big to add the aeration supply gas pressure, causes diaphragm shorter relatively work-ing life, and becomes its three big weakness, has limited its development.Another kind of is the ceramic aerator of Chang Kaikong, structure such as Chinese patent CN2376471, CN1958464, CN2890041, CN3584426 are said, basic structure such as Fig. 1, comprise bowl-type or dish type distribution plastic feet 1 and the semisphere or tabular pottery (corundum) the micro-pore aeration element 2 that are pressed together on distribution base top, periphery is by plastic ring gland 3 and plastic feet pressing, in rubber seal 4 sealings are arranged.Because aerator is made up by three kinds of differing materials (pottery, rubber seal, plastic seat), add that the ceramic capillary aeration board is for easily mincing, combination is exerted pressure and can not be too big, thereby the sealing position easily produces gas leakage after using for some time, influence aeration efficient: secondly, the ceramic capillary aeration board is the compression chord effect on the one hand, is subjected to the supply gas pressure impulse force on the other hand again, fatigability very easily takes place in the use break; Besides, because ceramic aeration board brittle nature, general dull and stereotyped aeration board can not be done greatly, is generally Ф 178mm, and service area is less relatively.And adopt semisphere corundum microporous aerator head, though can reduce the aeration board percentage of damage, one is that the aeration service area is less relatively usually, is generally Ф 178mm; The 2nd, increased area, manufacture difficulty increases, and for example big spherical pore is difficult to evenly can cause the aeration lack of homogeneity, and the 3rd, spherical doing greatly, not only benzene is heavy, and the occupy-place volume is bigger, has increased packed and transported cost (the engineering usage quantity is mostly several thousand to several ten thousand).
Above-mentioned deficiency still has is worth improved place.
The utility model content
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, and providing a kind of sintering to finish can use, and does not need otherwise combined, and the big ceramic plate of the aeration service area hole aerator that declines.
The utility model purpose realizes, main improvement is that the supporting plate of aeration board and bottom formation sealing chamber all adopts ceramic making, and directly form whole by clay bonding sintering both, aeration board and base plate form the sintered type sealing, thereby overcome above-mentioned the deficiencies in the prior art, realized the utility model purpose.Specifically, the utility model ceramic plate hole aerator that declines, comprise the ceramic plate hole aeration board that declines, it is characterized in that micro-pore aeration plate below is ceramic airtight similar shape supporting plate, pottery supporting plate bearing surface has radially, and gas is communicated with alternate annular convex ring, pottery supporting plate thickness is embedded with hollow ceramic and connects and chew, and the ceramic capillary aeration board, forms the airtight ceramic supporting plate of air chamber, pottery and is sintering between connecing and chewing and connects.
Utility model is said:
The ceramic plate hole aeration board that declines can be dull and stereotyped or the little arch structure of similar plate-like, wherein a kind ofly is preferably little arch disc structure, and little arch shape is not yielding when drying, helps improving yield rate.It forms material, can be the broad sense pottery, can not limit, and is wherein a kind of comparatively commonly used for adopting emergy sinter molding (other prescription pottery equally can).Because aeration board is that multi-point support is connected with base plate, the crimping of more former periphery individual pen can significantly improve the aeration board folding strength, therefore can strengthen the aeration plate service area, for example makes the little arch aeration disk of the big service area pottery of Ф 260-300mm.
Pottery supporting plate bearing surface radially gas is communicated with alternate annular convex ring, and its effect one is to form the multiple spot bonding connection of supporting plate to aeration board, to strengthen both strength of joint, and the separation that prevents to come off, the 2nd, evenly to the aeration board air feed.Wherein a kind ofly be preferably alternate concentric ring.End face is better curved, can reduce bonding aeration board aerating pore is stopped, improves aeration board aeration uniformity coefficient.
The utility model ceramic plate hole aerator that declines, with respect to prior art, owing to adopt with the ceramic capillary aeration board, form the airtight ceramic supporting plate of air chamber, the pottery hickey, the combination of three stupalith clay bondings, through kiln high temperature sintering adhesive structure, has bonding firmly, can not separate in the use, thoroughly overcome prior art assembled ceramic micro-hole aerator, easily gas leakage and the easily broken two big fatal shortcomings of aeration board in the use make and hang down aeration resistance by the ceramic capillary aerator (the clear water resistance≤3000Pa), liquid-gas interface is greatly long-pending usually, the bubble diffusion is evenly saved the operation energy consumption advantage and is given full play to.In addition, multiple spot rest sintering connects, also help the ceramic aeration board fatigue resistance ability of breaking that improves, thereby can strengthen single aeration board area, and for example make the big service area aeration board of Ф 260-300mm, reduced the aerating system resistance especially, utility model Ф 260mm aeration board atmospheric drag 456pa, clear water resistance 892pa (only common 1/3), and the aeration service area is big, can also save installation cost; Adopt to form the airtight ceramic supporting plate of air chamber, can also support, thereby need increase fire-resistant liner plate separately can omit ceramic aeration board sintering the time, help reducing and fire cost as sintering aeration board preventing deformation.Combination rear plate or little arch square position iterative structure, it is relatively little to take up room, instant packed and high-density transportation.The sintered bond kiln discharge can be directly used in use in addition, and finished product does not have assembly, and packing is simple, transportation safety, easy for installation.
