The oxidation ditch extension brushes the insolation internal combustion engine is one kind processes in the city and the industrial waste has the strong competitive power one biological treatment craft, suits our country national condition, at present is promoting the application vigorously. has functions and so on oxygenizement, mix, advancement to brush the insolation internal combustion engine in a body's YHG series horizontal axis extension is in the oxidation ditch sewage treatment system the most main mechanical device. Is Tsinghua University environmental science and the engineering department for several years concentrates on study the development, one of this company manufacturing's newest achievements, this product's essential part has obtained three item of national monopolies. At present has formed from consummation and so on experiment, design, processing, installment, service production systems. The YHG series extension brushes the aeration machines and tools to have the oxygenizement ability to be high, the power consumption province, the noise are low, the structure is simple, maintenance characteristics and so on convenient, continuous running.

     The structure and characteristic the horizontal axis extension brushes the insolation internal combustion engine mainly by the electrical machinery, the decelerating device, the extension to brush parts and so on main body and joint supporting is composed.

(one) bridge-type unique feature

　　 The bridge-type structure extension brushes is suitable for the middle and small scale oxidation ditch sewage factory. Between the electrical machinery and the speed reducer uses the triangle belt connection, the speed reducer the main axle which brushes through the flexible coupling and 2 bearing seats and the extension is connected, the electrical machinery, the speed reducer, the extension brush fix on the rack. On the rack has the platform and the parapet hand guard, the entire equipment fixes depending on the rack on the oxidized trench. The electrical machinery uses the horizontal-type electrical machinery, including ordinary electrical machinery, multipolar speed change electrical machinery as well as limitless speed change electrical machinery; The speed reducer uses the standard the cycloid pin gear speed reducer. Uses the bridge-type structure manufacture installment great convenience, may after the factory the complete machine assembly the packing transports to the scene, installs when only need adjust the level in the pre-calculated position then.

(two) non-bridge-type unique feature 

　　 1st, electrical machinery: In order to meet alternately the work type oxidation ditch craft needs, has two kind of vertical electrical machinery, one kind for polarity reversal two speed three-phase asynchronous motor, one kind for list fast three-phase asynchronous motor. 

　　 2nd, decelerating device 

　　 The decelerating device uses the circular cone - - second-level cylindrical gears rotation, all gears are the hard tooth face, bearing capacity are big. 

　　 3rd, joint and contract way

　　 Abandons traditional the shaft coupling and the bearing seat coupling way, decelerates after the speed reducer does not pass through the traditional shaft coupling and the bearing seat, transmits directly through the flexible coupling the speed for the extension brushes, the terminal bearing seat uses the three dimensional zoom type bearing seat, has guaranteed as a result of the main axle expand with heat and contract with cold security. This kind of joint and the support pattern to carry on the accurate installment and the long time continuous working provide the guarantee. 

(three) the YHG series extension brushes the aeration turning point to brush partial unique feature the host to use the hot rolling seamless steel pipe processing manufacture, the outside surface after the galvanization or the bitumastic enamel antiseptic treatment, enhances the anti-corrosive degree, increases the main axle service life; The leaf blade uses tough and the intensity high stainless steel ramming formation, uses the special structure, the intensity is high, the anti-corrosive performance is good, but the change is strong, the service life is long, the leaf blade assumes the eccentric pattern on the main axle, enables the continual water leakage and increases the start and the movement stability. the model shows
