Abstract
The utility model relates to a dual-wheel vertical lifting type surface aerator, comprising a prime motor, a water power differential transmission system, a jet flow guiding system, a flow guiding pipe, impeller wheels, a supporting device, etc. The high-speed pump wheel of the water power differential transmission system strengthens the lift of deep water through the flow guiding pipe and cooperates with the impeller wheels to realize the water power differential transmission and the jet flow guiding air, and the impeller wheels lift water further and make water jump. The utility model with the advantages of good performance, simple structure, low cost and easy use and maintenance can not only be used for the surface aeration, but also can be used to increase oxygen in the aquiculture.
Description
The utility model metal surface aerator and oxygenating machine class.
The prior art of this technology only possesses the top layer aerator and the oxygenating machine of single low speed impeller by the mechanical deceleration device transmission.Not only cost is higher for the deceleration device of these machines, weight is bigger, and does not participate in aeration or oxygenation work directly.The impeller negative pressure inlet of these machines, or the vacuum tightness that produces by suction eye, or vacuum side of blade produces during by wheel rotation vacuum tightness sucks air, thus do not reduced suction, the aeration ability of impeller with having.
The purpose of this utility model is when improving original transmission mechanism, and the overall structure that comprises impeller is improved, and a kind of twin type vertical-lift formula surface aeration machine is provided.
The utility model technical solution:
A kind ofly be packed in the twin type vertical-lift formula surface aeration machine of forming on the boss of supporting base assembly 9 by the supporting bar 7 usefulness bolts of three floating drums 8 by separately, this function flies on the water surface of culturing the waters, and by the lanyard between floating drum and ground, it is characterized in that primover passes through a pair of water pump shaft coupling 11 and links to each other with impeller shaft 12, impeller shaft 12 tops are by two rolling bearing location in the supporting base, the bottom is with the strong pump impeller 4 that connects, and compress with specialized nut, big impeller 1 is enclosed within impeller shaft 12 middle parts by water lubricated bearing 6, the frustum surface of big impeller 1 is uniform to be equipped with some straight blades, its laying angle is between 5 °～20 °, evenly have some circle air inlet ports 2 on the frustum bottom surface alternately, and install a last guide vane wheel 3, and pump impeller 4 with bolt, guide vane wheel 3, big impeller 1, thrust-augmenting nozzle 5 is all installed with original machine output shaft is concentric.
Wherein the frustum of big impeller 1 surface is uniform in the utility model is equipped with several straight blades, and its laying angle is 11.5 °, evenly has two row's air inlet ports 2 on the frustum bottom surface alternately.
The utility model advantage:
Twin type vertical-lift formula surface aeration engine efficiency height, at the bottom of the cost, the life-span is long, and is simple in structure, uses easy to maintenancely, both can be used for carrying out surface aeration, can be used to oxygenation in aquaculture again.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model blade wheel structure orthographic plan.
Fig. 3 is Fig. 2 A-A sectional view.
Fig. 4 is the utility model blade wheel structure sectional view.
Below in conjunction with accompanying drawing the utility model is further described:
Twin type vertical-lift surface aeration machine is made up of several parts such as primover, waterpower differential transmission systems, jet bleed air system, thrust-augmenting nozzle 5, big impeller 1 and supporting devices.Pump impeller 4 in the hydraulic transmission system, guide vane wheel 3 and big impeller 1 are coaxial installation, wherein big impeller 1 is to be enclosed within impeller shaft 12 with water lubricated bearing 6 skies, and guide vane wheel 3 then is packed on the lower plane of big impeller 1 with one heart or is directly extended to the centre by the blade of big impeller 1 and constitutes.Primover of the present utility model is an electric motor 10, also can adopt other forms, such as oil motor, wind wheel etc.Supporting device of the present utility model can be stationary and three island float on-float offs.Jet bleed air system of the present utility model is to constitute by means of the annular gap that forms between pump impeller 4 back shrouds and guide vane wheel 3 back shrouds, and total open area in its gap is 1/500～1/1000 with the area ratio at big impeller 1 maximum diameter place.The semiclosed-type impeller of big impeller 1 approximate mixed of the present utility model.Its back shroud is that reverse frustoconic, rounding platform cone angle are 110 °～160 °, and the big end of round platform links to each other with an annular shirt rim with the circular arc transition, and the angle of shirt rim and horizontal plane is 10 °～-10 °; Blade quantity is got even number by frustum upper surface girth after 100～200 millimeters, and evenly layout is installed on frustum-conical surface, and the laying angle of blade is 6 °～12 °, and the angle between the frustum tangent plane is 90 °～60 °.Pump impeller 4 of the present utility model is to adopt high-revolving centrifugal or mixed flow impeller.
Supporting system is installed on the job site with primover, transmission shaft and coaxial mounted pump impeller 4, guide vane wheel 3, thrust-augmenting nozzle 5 and big impeller 1, and makes the highest plane of big impeller 1 parallel with the water surface, and is lower than 0～40 millimeter at horizontal plane.After starting primover, pump impeller 4 is by thrust-augmenting nozzle 5 suction deep waters and enter guide vane wheel 3.At this moment, by stopping, state is speedup gradually under the drive of guide vane wheel 3 on the one hand big impeller 1, and finally with certain stable differential rotation, once more water lift and cause hydraulic jump; On the other hand, pump impeller 4 can form the horizonally projected jet air inlet with the gap location of guide vane wheel 3, and and then forms gas-liquid impingement, stirring, dissolution process in guide vane wheel 3 and big impeller 1.Water curtain when the evagination shirt rim of big impeller 1 helps hydraulic jump forms, thus air-breathing, the molten gas ability when strengthening hydraulic jump.
