Transmission device of mud throwing spoon for shallow-tank air-floatation water purifier

Abstract

The invention relates to a transmission device of a mud throwing spoon for a shallow-tank air-floatation water purifier. The transmission device is characterized in that: a hollow output shaft speed changing machine is fixed at the inner side of a speed changing machine seat which can carry out pitching swinging round the center line of an angle adjusting shaft, the speed changing machine seat is supported on the angle adjusting shaft by an angle adjusting shaft bushing through coaxial holes at the two sides, angle adjustors are arranged at the two ends of the angle adjusting shaft, vertical angle adjustor positioning shafts which are arranged below the angle adjustors are inserted into positioners inlaid with positioner bushings, and the positioners are arranged on the side face at the outer end of a slewing rack. Being provided with three nylon bushings in total, the transmission device has good shock absorbing and cushioning performances; as the elastic deformation of the angle adjustors to some degree also has the function of cushioning, the transmission of the transmission device is fairly stable; moreover, the impact dynamic load of the speed changing machine is low, the noise is low, and the service life is long. The transmission efficiency of the transmission device is far higher than that of chain transmission and the transmission of a shaft joint.

AI Technical Summary

Problems solved by technology

The chain drive has the following disadvantages: 1. The mud skimmer is intermittently skimmed

2. Due to the need to bear large impact dynamic loads and often lack of reliable lubrication, the service life of sprockets, especially chains, is short

3. Heavy daily maintenance workload

Some users do not set up a special person to take care of the water purifier. This shortcoming will cause problems and lead to an increase in the failure rate of the water purifier.

4. Low transmission efficiency increases energy consumption

[0011] This transmission mode also has another disadvantage that cannot be ignored: the installation and adjustment requirements are relatively high, and compensation adjustments must be made regularly or irregularly, and the adjustment requirements are relatively high, and it is difficult for unskilled personnel to do it.

Although the installation angle error and the subsequent angular offset will be reduced in a considerable proportion at the coupling, stricter restrictions are still required

If the installation angle error is too large, or the angular offset that occurs in the future is too large and is not adjusted in time, or the adjustment is incorrect, it will cause the speed changer, the bearing in the bearing housing and the coupling to bear a large additional load, which will increase energy consumption. Shorten life, or even damage
