Description

One kind turning brush, rotary disk aerator

Technical field

The utility model relates to sewage treatment fields, more particularly to a kind of turn of brush, rotary disk aerator.

Background technique

Turn brush, rotary disk aerator also known as aeration turn plate, belongs to the trunnion axis disc type surface plug-flow aeration in mechanical aeration machine Device.Aerator is made of aeration turn plate, the bearing for horizontally rotating main shaft and both ends, motor and retarder, but in the prior art Turn brush, rotary disk aerator speed reducer and horizontally rotate connection between main shaft connected using keyway, to speed reducer output shaft with The diameter of axle matching requirement degree for horizontally rotating main shaft is high, and keyway connection is easy stuck, disassembly difficulty；Due to horizontally rotate main shaft compared with Long, stress is big, and easy torsion is bad, so replacement frequency is high.

The output shaft that speed reducer in the prior art is equipped with is solid shafting, need to shaft coupling by speed reducer with horizontally rotate Main shaft is fixed, and speed reducer device is big, and civilwork engineering quantity is big.

Utility model content

Purpose of utility model: the purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of turn of brush, plate-spinning Aerator.

Technical solution: in order to reach above-mentioned purpose of utility model, the utility model is specifically achieved like this: Yi Zhongzhuan Brush, rotary disk aerator, including speed reducer, motor, horizontally rotate main shaft, positioned at two bearing blocks for horizontally rotating main shaft both ends And several aeration turn plates horizontally rotated on main shaft are arranged in, the output shaft of the speed reducer is hollow shaft, horizontally rotates main shaft For hollow shaft, speed reducer output shaft and horizontally rotating is connected between main shaft using expansion coupling sleeve.Horizontally rotating main shaft transmitting When torque, in terms of radial section, the effect of outer place transmitting effective torque is bigger, needs to transmit larger torque in shaft When, it is necessary to the thicker diameter of axle, and since the effect in axis part transmitting torque is smaller, so on the one hand can using hollow shaft To reduce the self weight of shaft, material on the other hand can also be saved；The output shaft of speed reducer is changed to hollow shaft can be to avoid holding By the radial load of axis；The output shaft of speed reducer is connected between main shaft using expansion coupling sleeve with horizontally rotating, and shaft coupling is eliminated Also civil engineering structure is optimized, civil construction cost is reduced.

Further, the speed reducer is vacantly placed and is provided with counter-force moment device on speed reducer.Speed reducer is vacantly placed It can reduce and horizontally rotate the curved of main shaft middle section and refuse, counter-force moment device fixes speed reducer, prevents speed reducer with level Rotate main axis.

Further, it is described horizontally rotate Surface heat-treatent reinforcing is carried out inside and outside main shaft.Horizontally rotating main shaft is Hollow shaft is strengthened stronger than the solid shafting intensity of same diameter after carrying out heat treatment reinforcement to inside and outside.

Further, it is described horizontally rotate disc brush is provided on main shaft between aeration turn plate gap, disc brush by disk and Bristle is constituted, and bristle is distributed in the two sides of disk and contacts with aeration turn plate.Since aeration turn plate is easy to be blocked up by the impurity in water Plug, to influence aeration quantity, after disc brush is arranged between the gap of aeration turn plate, bristle is under the disturbance of water flow to aeration turn plate It is scrubbed, so that the tamper in aeration turn plate is scrubbed out.

Further, the bristle is vertically set on disk.Washing effect is more excellent.

The utility model has the beneficial effects that the utility model has the advantages that compared with traditional technology

1, speed reducer output shaft uses hollow shaft in the utility model, horizontally rotates main shaft using hollow shaft, speed reducer is defeated Shaft is connected between main shaft using expansion coupling sleeve with horizontally rotating, on the one hand to speed reducer output shaft and the axis for horizontally rotating main shaft The requirement of diameter matching degree is low, on the other hand eliminates shaft coupling, optimizes civil engineering structure, reduces the construction cost of civil engineering, hollow The weight that the use of axis reduces axis itself also saves material.

2, it is provided with disc brush between aeration turn plate gap on horizontally rotating main shaft in the utility model, so that bristle is in water Aeration turn plate is scrubbed under the disturbance of stream, so that the tamper in aeration turn plate is scrubbed out.
