Abstract
The utility model relates to a disk-type aeration device of an oxidation ditch, which is composed of two semicircular disk bodies and the shaft center of a circular disk. The utility model is characterized in that convex small blocks of a trapezoidal oblique prism cone are regularly and densely arranged on the two semicircular disk bodies in a radial shape. A plurality of circular small concave parts are arranged among rows of trapezoidal small blocks, and the top surfaces of the trapezoidial small blocks are provided with small circular concave parts. The utility model which is matched with a flooded flow guiding plate which is arranged in an oxidation ditch for use can change the vertical distribution of the flow speed of small flow. The water depth of the oxidation ditch is increased from three meters to five meters, and the oxygen transfer efficiency can exceed that of the like foreign advanced product. The disk-type aeration device of an oxidation ditch of the utility model is suitable for aeration equipment which carries out the biochemic treatment for sewage.
Description
The utility model relates to a kind of aerator that sewage is carried out biochemical treatment, is specially adapted to the special-purpose aerator of oxidation ditch.
At present, most surface aerating machine of falling the umbrella shape or the aeration rotary brushs of adopting of the aerator of oxidation ditch, this just makes that the oxidation ditch floor space is bigger, the degree of depth of oxidation ditch generally can only make applying of oxidation ditch process be subjected to certain restriction at 3.0～3.5 meters.
The purpose of this utility model is a kind of novel oxidation ditch disc type aerating apparatus of design, and it is simple in structure, and being used for oxidation ditch process saving energy, horizontal thrust, to reach oxygenation capacity greatly big.
Oxidation ditch disc type aerating apparatus of the present utility model, form by two semicircle disk bodies and disc axis, disk body is provided with strengthening rib, be provided with the breach that alleviates deadweight between strengthening rib, it is characterized in that: on disc, be radial gathering regularly and arrange trapezoidal oblique prism cone raised nubs, each is arranged and is provided with a large amount of circular little recessedly between the trapezoidal fritter, and it is recessed that the end face of trapezoidal fritter is provided with roundlet.
The optimum size of described trapezoidal oblique prism cone fritter is: 24 * 20 millimeters, the circular little recessed degree of depth is 3～6 millimeters.
The principle of work of oxidation ditch disc type aerating apparatus of the present utility model is, during the aeration turn plate rotation, before the trapezoidal oblique prism cone protruding block of main dependence promotes current direction, simultaneously bigcatkin willow is gone out the water surface and form liquid film, the globule contacts with atmosphere airborne oxygen is dissolved in the water, all circular little air in recessed simultaneously, also that it is contained oxygen is transferred to and makes it oxygenation in the water.Be arranged on the recessed increase of roundlet on the trapezoidal small lugs end face liquid film that pumps up water, the dissolved oxygen of the globule has improved oxygen transfer efficiency
Oxidation ditch disc type aerating apparatus of the present utility model, because disk diameter is big, trapezoidal oblique prism cone raised nubs construction size is different with existing rotating disk, flood the supporting use of flow deflector in the oxidation ditch with being arranged on, can change the perpendicular of flow rate of water flow with distributing, thereby raising that can be bigger just can be brought up to 5.0 meters by 3.0 meters with the depth of water of oxidation ditch to the thrust of water; Improve the depth of water and can save occupation of land and construction costs, also enlarged the use range of oxidation ditch simultaneously: because the circular little recessed general big degree of depth of rotating disk that adopted, it is recessed to have set up roundlet at trapezoidal small lugs end face especially again, improved oxygen transfer efficiency, no matter be the oxygenation capacity of single disc, or oxygen-transfer efficiency (unit of electrical energy oxygenation capacity) has all surpassed external advanced like product.
The basic mechanical design feature of oxidation ditch disc type aerating apparatus of the present utility model is:
Oxygenation capacity: 1.65KG/H,
The highest oxygen-transfer efficiency: 2.38KGO
2/ KW.H
Branch is changeed in rotating speed: N=49～60
Economize on electricity 25%.
Oxidation ditch disc type aerating apparatus of the present utility model is suitable for the aerator that sewage is carried out biochemical treatment.
Below in conjunction with drawings and Examples oxidation ditch disc type aerating apparatus is described further.
Fig. 1 is the structure iron of oxidation ditch disc type aerating apparatus
Fig. 2 is the A-A sectional view of Fig. 1
Fig. 3 is an oxidation ditch disc type aerating apparatus partial enlarged drawing
As shown in the figure, a kind of oxidation ditch disc type aerating apparatus, form by two semicircle disk bodies 1 and disc axis 2, disk body is provided with strengthening rib 3, be provided with the breach 4 that alleviates deadweight between strengthening rib, it is characterized in that: be the radial trapezoidal oblique prism cone raised nubs 5 of gather arranging regularly on disc, each is arranged and is provided with a large amount of circular little recessedly 6 between the trapezoidal fritter, and the end face of trapezoidal fritter is provided with roundlet recessed 7
Described trapezoidal oblique prism cone raised nubs is of a size of: 24 * 20 millimeters, the circular little recessed degree of depth is 4 millimeters.
Claims (2)
1, a kind of oxidation ditch disc type aerating apparatus, form by two semicircle disk bodies and disc axis, disk body is provided with strengthening rib, be provided with the breach that alleviates deadweight between strengthening rib, it is characterized in that: on disc, be radial gathering regularly and arrange trapezoidal oblique prism cone raised nubs, each is arranged and is provided with a large amount of circular little recessedly between the trapezoidal fritter, and it is recessed that the end face of trapezoidal oblique prism cone fritter is provided with roundlet.
2, oxidation ditch disc type aerating apparatus as claimed in claim 1, it is characterized in that: the optimum size of described trapezoidal oblique prism cone raised nubs is: 24 * 20 millimeters, the circular little recessed degree of depth is 3～6 millimeters.
