Aeration device

Abstract

The invention relates to an aeration device, and belongs to the technical field of sewage treatment equipment. The aeration device comprises a frame (1), a motor (2) and an impeller (7), a reduction gearbox (4) is arranged on the frame (1), the impeller (7) comprises a plurality of impeller blades (8), reinforcing plates (9) are arranged among the impeller blades (8), a lubricating oil circuit (5) is arranged on the reduction gearbox (4), an oil hole is additionally formed between bearings of the reduction gearbox (4), and the lubricating oil circuit (5) is communicated with the oil hole between the bearings of the reduction gearbox (4). According to the aeration device, the reinforcing plates are additionally arranged among the impeller blades, strength of the impeller is improved, the service life of the impeller is prolonged, the lubricating oil circuit is additionally arranged on the reduction gearbox, so that lubricating oil circuit flows onto the bearings of the reduction gearbox, abrasion of the bearings is decreased, labor waste caused by frequent replacement of the bearings is avoided, and production efficiency is improved.

Description

technical field [0001] The invention relates to an aeration device, which belongs to the technical field of sewage treatment equipment. Background technique [0002] Oxidation ditch is one of the processes for urban sewage treatment. Its specific ditch type usually uses aeration to purify wastewater. However, the traditional aeration device lacks the following defects: [0003] 1. The resistance of the impeller during the rotation of the sewage surface is relatively large, and the impeller blades are easily deformed and damaged, which will affect the service life of the impeller. [0004] 2. The motor is arranged on one side of the reduction box, which occupies a large area, and when the aeration device is working, the motor is corroded by the splashed sewage, and the replacement of the motor increases the production cost. [0005] 3. Under the high-intensity work of the aeration device, the bearing on the reduction box is extremely easy to wear and tear. Frequent replacem...
