Abstract
The utility model relates to a flow-pushing submersible agitator stirring mill, which can obtain optimum flow field distribution by smaller power in a sewage treatment oxidation ditch. The utility model has the structure that a submersible electric machine (5), a pin tooth housing (6) of a cycloid pin wheel speed reducing mechanism, and a machine seat (2) are fixed into an integral body by bolts, an input shaft of the cycloid pin wheel speed reducing mechanism is just an output shaft of the submersible electric machine, the input shaft (4) and an output shaft (3) of the cycloid pin wheel speed reducing mechanism are together fixed on a bearing, the input shaft (4) is fixed with a bearing inner ring by a shaft head, the output shaft (3) is fixed with a bearing outer ring by a bearing sleeve, and the other end of the output shaft (3) is fixed in the bearing of the machine seat. The utility model adopts the cycloid pin wheel speed reducing mechanism to replace a cylinder gear speed reducer; therefore, the utility model has the characteristics of small size, streamlined performance, light weight, and smooth flow way; furthermore, the utility model is easy for reasonable layout of flow fields of a water body, the biochemical reaction is quickened and the level of sewage treatment is raised.
Description
Affiliated technical field
The utility model relates to a kind of sewage disposal oxidation ditch process and implements establishment underwater installation-stream pulling type diving mixer in water body flow field in mixing of activated sludge and the ditch.
Background technology
The basic comprising of the stream pulling type diving mixer of prior art is submersible motor reaches setting by reducing gear a output speed, assembling stream pulling type diving Agitator Impeller on the output shaft of reducing gear, impeller is with at the uniform velocity rotation during duty, the movement locus of two blades on the impeller forces to be divided into a horn-like reverse taper with water body, therefore set up the pressure reduction of water body front and back, water body advances, to realize the function of equipment.The leading indicator of estimating diving performance quality is: under the condition of certain input power, obtain best hydro-flow thrust, set up certain power minimum that Flow Field Distribution consumed in other words.The key that realizes this purpose has two: one, and the energy of motor is passed to the part of impeller, i.e. reducing gear; The 2nd, the output energy of reducing gear is passed to the part of liquid, i.e. impeller.Under the certain situation of impeller, crucial at reducing gear.
China introduces external stream pulling type diving mixer approximately in the early 1990s, use the waterpower design method of jet circle in design, improve mobile drift rate by the control mode of becoming a mandarin, set up the flow field, almost all adopt roller gear retardation method in the manufacturing of reducing gear, the whole reducing mechanism volume is big, the noise height, heavy, the resistance of input duct is big, and propulsive efficiency is low.
Summary of the invention
In order to overcome the shortcoming that prior art exists, the purpose of this utility model provides a kind of cycloidal planetary gear speed reducer structure and replaces cylinder gear speed reducer, realizes that volume is little, streamlined, noise is low, lightweight stream pulling type diving mixer.
For achieving the above object, the technical solution adopted in the utility model is: adopt cycloidal-pin wheel deceleration principle, with submersible motor, the pin wheel housing of cycloidal planetary gear speed reducer structure and support are an integral body by bolting, cycloidal planetary gear speed reducer structure profile is streamlined, be connected with support with motor and be rounding off, cycloidal planetary gear speed reducer structure power shaft is the submersible motor output shaft, the power shaft of cycloidal planetary gear speed reducer structure and output shaft are with being fixed on the bearing, power shaft is fixed in bearing inner race with spindle nose, output shaft is fixed in bearing outer ring with bearing holder (housing, cover), and the output shaft other end is fixed in the support bearing.
After adopting above technical scheme, this stream pulling type diving mixer volume is little, streamlined, in light weight, adjusts flexibly, good seal performance, the resistance of input duct is little, and runner is unimpeded, and fltting speed is fast, the plug-flow distance, be easy to water body flow field rational deployment, reduce regional dead angle, stop the dirt precipitation, accelerate biochemical reaction, improve the sewage disposal level.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of cycloidal planetary gear speed reducer structure.
Among Fig. 1,2, impeller 1, support 2, output shaft 3, power shaft 4, submersible motor 5, pin wheel housing 6, gear pin 7, pin gear sleeve 8, pin 9, roller 10, eccentric bushing 11, Cycloidal Wheel 12.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1,2, the stream pulling type diving mixer mainly provides power source by self-control submersible motor 5 for the stream pulling type diving mixer, by motor power shaft 4 transferring power to deceleration component, these parts have adopted cycloidal planetary gear speed reducer structure transmission principle, transfer its energy to eccentric bushing 11 by power shaft 4, utilize the eccentric throw of eccentric bushing, drive cycloidal-pin wheel 12 along pin wheel housing upper fixing element gear pin 7, pin gear sleeve 8 is done cycloid rolling friction campaign, every Cycloidal Wheel has 50% tooth and pin toe joint to touch, all the time be symmetrically distributed, guarantee reposefully energy to be passed through pin 9, roller 10 is passed to output shaft 3, thereby drive 1 rotation of main working parts impeller, reach the Flow Field Distribution requirement of setting.
Claims (2)
1, a kind of stream pulling type diving mixer, comprise submersible motor (5), support (2), impeller (1) transition connects, it is characterized in that: submersible motor (5), pin wheel housing of cycloidal planetary gear speed reducer structure (6) and support (2) are an integral body by bolting, cycloidal planetary gear speed reducer structure power shaft is the submersible motor output shaft, the power shaft of cycloidal planetary gear speed reducer structure (4) is fixed on the bearing together with output shaft (3), power shaft (4) is fixed in bearing inner race with spindle nose, output shaft (3) is fixed in bearing outer ring with bearing holder (housing, cover), and output shaft (3) other end is fixed in the support bearing.
