Embodiment 1

[0024] Example 1, such as figure 1 As shown, a surface aerator includes a buoy 1, a motor 21 installed on the buoy 1, and an axial flow impeller 24. The horizontal center of the buoy is provided with a water absorption channel 12 connected up and down. A water inlet 11 communicated with the water absorption channel 12 is provided, a water outlet 13 communicated with the water absorption channel 12 is provided on the upper part of the buoy, the motor 21 is arranged above the water outlet 13 and vertically arranged, and the output shaft of the motor is placed downward and The pump shaft 22 is connected, and the motor 21 is provided with a shroud 23 surrounding the pump shaft 22. The shroud 23 is set corresponding to the water outlet 13. The bottom of the pump shaft 22 is exposed from the shroud 23 and extends into the water-absorbing The channel 12 is also equipped with the above-mentioned axial flow impeller 24 .

[0025] In the water suction channel 12, the motor 21 drives t...

Embodiment 2

[0035] Embodiment 2, in order to make the rainproof cover 3 not only play the role of heat dissipation of the motor but also play the role of rainproof. Such as Figure 6 As shown, the present invention is provided with an annular ventilation ring 32 between the rain shield cap 31 and the end cover 25 , and the motor end cover 25 is fixed to the motor body by screws 251 . The ventilation ring 32 has ventilation openings 321 distributed along the circumferential direction, and an annular rain-shielding ring 33 is provided on the inner peripheral side of the ventilation ring. The ventilation ring 32 is used to realize ventilation and heat dissipation of the motor, while the rain-shielding ring 33 can effectively prevent rainwater from intruding into the motor.

[0036] Such as Figure 7 As shown, the ventilation ring 32 is in the shape of a rectangular strip after being unfolded, and the ventilation opening 321 is a rectangular notch provided at the bottom of the ventilation r...

Abstract

The invention discloses a surface aerator with a vertical motor for a sewage treatment system. The surface aerator comprises a float bowl and a vertical motor and an axial-flow impeller mounted on the float bowl, wherein a water absorption channel connected up and down is arranged at the horizontal center part of the float bowl; a water inlet communicated with the water absorption channel is formed below the float bowl; a water outlet communicated with the water absorption channel is formed in the upper part of the float bowl; the vertical motor comprises a motor body and an end cover covering the upper end of the motor body; a rainproof cover is arranged above the end cover; the rainproof cover comprises a conical rainproof cap; an annular ventilation ring is arranged between the rainproof cap and the end cover; ventilation openings are distributed on the circumferential direction of the ventilation ring; an annular rainproof ring is arranged on the inner peripheral side of the ventilation ring; a motor output shaft is connected with a pump shaft; and the bottom of the pump shaft extends into the water absorption channel, and the axial-flow impeller is mounted. The surface aerator disclosed by the invention can effectively prevent rainwater from invading the motor.

Description

technical field [0001] The present invention relates to aeration equipment. Background technique [0002] Such as Figure 5 As shown, the existing rainproof cover 3 is made up of a conical rainproof cap 31 and three L-shaped columns 30 welded, and the motor end cover 25 is connected with the feet of the L-shaped columns 30 with bolts 301, which cannot be effectively used in actual use. Prevent rainwater from invading the motor end, causing the motor to burn out due to water ingress. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a surface aerator with a vertical motor for a sewage treatment system, so that the rain cover can not only play the role of heat dissipation of the motor but also play the role of rain protection. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: a surface aerator with a vertical motor for a sewage treatment s...
