Embodiment:
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
See Fig. 1, a kind of multi-functional mechanical mixing of the present invention aerating machine, comprises tubular shaft 5, inlet pipe 2, air volume regulating valve 3, workplatform 4, aeration blade 6 and motor driver 1; Wherein, comprise workplatform 4, be arranged on the motor driver 1 above workplatform 4, vertical direction runs through the tubular shaft 5 of workplatform 4, and motor driver 1 output terminal is connected with one end of tubular shaft 5, the other end of tubular shaft 5 is communicated with the aeration blade 6 with hollow cavity, and tubular shaft 5 is communicated with inlet pipe 2 being positioned at the sidewall above workplatform 4, inlet pipe 2 is provided with air volume regulating valve 3, and inlet pipe 2 along the radial communication of tubular shaft 5 on tubular shaft 5.The shape of workplatform 4 can be circle, square or regular regular polygon, and aeration blade 6 is hollow cone blade.
The quantity of preferred aeration blade 6 be 2n (n=1,2,3 ...) individual, and every 2 aeration blades 6 along tubular shaft 5 radial symmetry be communicated with on tubular shaft 5.
In order to understand further the present invention, now an explanation is done to its principle of work.
A kind of multi-functional mechanical mixing of the present invention aerating machine, motor driver 1 drives tubular shaft 5 to rotate thus drives aeration blade 6 to rotate and produces negative pressure, air intake tubular shaft 5 is released to water body, water extraction is risen to top water body by the lift that aeration blade 6 rotation simultaneously produces, and the upper and lower working cycle of water body realizes mixed effect; Aeration blade 6 high speed rotating plays the effect of chopping bubble, and then improves oxygen transfer rate, strengthens oxidation effect, and aeration blade rotates the mixing effect produced and also further increases storehouse, lake water body oxidation effect.
Embodiment:
See Fig. 1, each formant is all detachable, is convenient to installation and maintenance.Motor driver 1 selects the speed adjustable current asynchronous motor of 60W, and tubular shaft 5 external diameter is 10mm, internal diameter 8mm, and length is 1000mm; Taper aeration blade 6 is total 2n (n=1,2,3,4) sheet always, and every sheet aeration blade 6 becomes 13 ° of angles with horizontal plane, be 77 ° with the angle of tubular shaft, and head loss when promoting water body to make aeration blade rotate is minimum; Aeration blade external diameter 36mm, plastics, inlet pipe 2 internal diameter 8mm, metal products, air volume regulating valve 3 is connected with inlet pipe 2, for adjusting air inflow quantity size.
During work, starter motor drive unit, water in the aeration blade of tubular shaft lower end can be thrown out of aeration blade because of the effect of centrifugal force, air is inhaled into tubular shaft because of negative pressure immediately, when motor speed arrives greatly a certain numerical value, in tubular shaft, negative pressure can make taper aeration blade through tubular shaft lower end of the air that is inhaled into and enter water body, carries out oxygenation to water body; Motor drives tubular shaft to drive taper aeration blade fast rotational, and around aeration blade, produce violent turbulent flow, the oxygen in air is accelerated and is delivered in water under the Main Functions such as violent turbulent fluctuation and bubble cutting, and undissolvable partial air can overflow the water surface; Simultaneously, motor drives tubular shaft to drive taper aeration blade fast rotational, upwards circulating water flow is formed in the peripheral water body of aeration blade, promote that the water body after oxygenation and other regions are not by the mixing of oxygenation water body by this circulating water flow, thus the dissolved oxygen concentration improved rapidly in whole water body, realize the quick oxygenation of water body.
When motor speed is lower than a certain numerical value, in tubular shaft, negative pressure is not enough to taper aeration blade through tubular shaft lower end of the air that makes to be inhaled into and enters water body, and now multi-functional mixing aerating machine can not carry out oxygenation to water body; Motor drives tubular shaft to drive taper aeration blade fast rotational, forms upwards circulating water flow, caused the mixing of the inner each several part water body in storehouse, lake by this circulating water flow in the peripheral water body of aeration blade.
As only needed mixed water body, as utilized mixing effect to control the algal blooms breeding of storehouse, lake, lower motor speed can be adopted; As needed mixed water body and oxygenation simultaneously, as utilized the algal blooms breeding of mixing effect control storehouse, lake and oxygenation to suppress the endogenous pollution of bottom of the reservior, lake mud and to carry out efficient oxygenation to biological treatment facility simultaneously, higher motor speed can be adopted.
