Abstract
The utility model relates to the filed of centrifugal blowers, and discloses a multi-level vane wheel wastewater treatment centrifugal blower. The multi-level vane wheel wastewater treatment centrifugal blower is composed of a bearing seat, a chassis, partition boards and vane wheels. The multi-level vane wheel wastewater treatment centrifugal blower is characterized in that 36 inlet ring gears are arranged at the position of an inlet ring of each vane wheel in a casting mode, a rib plate and fins are arranged on the bearing seat, and annular plate-shaped elastic pieces are installed inside the bearing seat. Due to the fact that the technical scheme is adopted, running is balanced, and noise is lowered.
Description
Technical field
The utility model relates to the centrifugal blower field, is a kind of multistage aluminium impeller sewage treatment centrifugal blower.
Background technique
At present, the centrifugal blower in above-mentioned flow and the scope of boosting divides vertical the installation in the employing level mostly.The sealing of between at different levels and impeller inlet circle place all is provided with independent seal element, thereby the processing of blower fan and installation workload are strengthened.Use common cast iron bearing case because radiating condition phenomenons such as seepage poor, that add thin oil are comparatively general, and make big multiple bearing adopt the grease lubrication mode, cause that bearing temperature is higher, bearing life shortens, and rotating speed can not improve.Conventional rotor adopts the Balance disc element to reduce blower fan to the axial force of rotor, because Balance disc is heavier, thereby has increased the rotary inertia of rotor, causes its axle overstriking, material increase, cost to rise.
Summary of the invention
The purpose of this utility model is to simplify blower fan structure, and provide a kind of through many places improved multistage aluminium bucket wheel blower.
The utility model is achieved in that by bearing support, casing, dividing plate and impeller to be formed, and it is characterized in that being cast with 36 import circle teeth at impeller inlet circle place, at bearing support gusset and fin is housed, and annular plate shape shell fragment is installed in bearing support.
Owing to adopted technique scheme, the running balance, reduced noise.
