Abstract
The present invention relates to a rotary disk aerating apparatus mounted on the horizontal shaft for making water treatment. It includes two semi-circular aerating rotating disks mounted on the horizontal shaft, aerating rotating disks and their upstream and downstream flow guide deflectors are formed into a set of high-effective water treatment equipment, the distance of the axle centre of the aerating rotating disk from water surface is 15-25 cm, the upstream flow guide deflector is straight plate, and the downstream flow guide deflector is a submerged buffle inclined toward downstream. It also provides the structure of the aerating rotating disk with oblique cone body, it can prevent sludge deposition and can greatly raise water treatment capacity.
Description
Technical field
The present invention relates to a kind of aerator of water treatment, especially a kind of rotating disk aerating apparatus that is installed on the transverse axis.
Background technology
Existing disk shaped is vertically rotated aerator, and disc surfaces does not have protruding thing of beveled cone and pit, is not used with flow deflector, and it is lower to exist oxygen-transfer efficiency, energy consumption is bigger, and is simultaneously less because of impellent again, makes the oxidation ditch depth have only 3～3.5 meters, take up an area of greatly, the water treatment amount is less, also deposition at the bottom of the pond.Limited applying of oxidation ditch.
Summary of the invention
Technical problem to be solved by this invention provides a kind of rotating disk aerating apparatus that is installed on the transverse axis, prevents sludgd deposition, improves water treatment amount and water treatment efficiency.
The technical solution adopted for the present invention to solve the technical problems is: this device comprises two semicircle aeration turn plates that are installed on the transverse axis, aeration turn plate by motor through the step-down gear driven rotary, the flow apron in aeration turn plate and its upstream, downstream is formed a covering device, 15～25 centimetres of the aeration turn plate distance of shaft centers waters surface, the upstream flow apron is the straight plate perpendicular to water (flow) direction, the downstream flow apron be the bottom inclined downstream flood the throwing baffle plate; The two sides of aeration turn plate is densely covered with the beveled cone of droping to the ground along the radius tangent direction, the cone tip part slyness of beveled cone, and point to the radius tangent direction, and being densely covered with pit between the beveled cone, surface of declined cone has shrinkage pool.An above-mentioned surface of declined cone oblique circular cylinder body shrinkage pool recessed down.The pit that gathers between the beveled cone on the above-mentioned aeration turn plate is cylindrical or hemispherical dimples.The angle of inclination of above-mentioned downstream flow apron be 55～65 ° of above-mentioned downstream flow aprons to the aeration turn plate distance of shaft centers from being 180～220 centimetres.Above-mentioned aeration turn plate axle center is to the radial slick and sly stiffening web in surface that is provided with of periphery.Be provided with the hole of weight reduction between the stiffening web on the above-mentioned aeration turn plate.Principle of work of the present invention: during the aeration turn plate rotation.Its surface is gone up the beveled cone of protruding water is thrown forward, while is by the centrifugal force of aeration turn plate, make along the liquid on aeration turn plate surface and carry air in the pit, formation liquid film or thin waterline are forwards skimmed, form a gas liquid mixture, thereby airborne oxygen is dissolved in the water by the preceding throwing depression curve shape of liquid film and tiny waterline.After current before throwing and pushing to were run into the downstream flow apron, it was to the front lower place that current change the flow direction, thereby has prolonged the dissolved oxygen time, has improved dissolved oxygen amount.
The invention has the beneficial effects as follows: aeration turn plate and upper and lower flow apron are combined into a high efficient aeration device, improve water treatment amount and water treatment efficiency.The stiffening web of the afterbody of beveled cone slyness and disk upper surface slyness can reduce the head loss that current pass through on the aeration turn plate, and the oblique circular cylinder shape shrinkage pool on beveled cone can increase the air amount of carrying, and does not increase, the power loss.Flow apron is set improves dissolved oxygen efficiency 11%.Current are behind flow apron, and cross-sectional flow has been distributed with big change, and water surface flow velocity reduces, and bottom velocity improves a lot, and can reach 0.25～0.3m/s, prevented to precipitate at the bottom of the pond.Also having improved simultaneously the depth of water of oxidation ditch, brought up to 5.2 meters by 3.0 meters, increased sewage load, is a kind of efficient water treatment device.
