Problems solved by technology

Existing mechanical aerators mainly include three types: water wheel type, impeller type and water spray type. Among them, the impeller type aerator is the most widely used, but most of the impellers of the existing impeller type aerators are on the wheel. The blades are welded on the shell, and the support plate is installed in the middle of the wheel shell. There is no window for the water on the wheel shell, so that the water body in the lower part of the wheel shell cannot flow effectively, which affects the oxygen increasing capacity of the aerator, and may make the fish Shrimp stuck in the lower part of the wheel shell

Embodiment Construction

[0030] Below with specific embodiment the utility model is described further, see Figure 1-7 :

[0031] Composite impeller, a plurality of single impeller blades 6 are combined with each other and connected with the support disc 12 to form an annular composite impeller 5, the single impeller blade 6: is set on one side of each fan-shaped wheel housing 18 There are large blades 7, and a water-passing window 9 is provided in the middle of each fan-shaped wheel housing 18, and small blades are arranged on the same direction as the large blade 7 on the side of each fan-shaped wheel housing 18 away from the window 9 of the large blade 7 8. The interlocking is that the buckle or buckle groove 16 provided on the front side of a sector-shaped wheel shell 18 is fastened to the buckle groove or buckle 10 provided on the rear side of the adjacent sector-shaped wheel shell 18 .

[0032] At least one small vane 8 and a water-passing window 9 are respectively arranged on each fan-shaped w...

Abstract

The invention belongs to the technical field of fishing culture machinery, and relates to a combined type impeller, a manufacturing method and an aerator manufactured by using the same. The combined type impeller is annular and is formed in a way that a plurality of single impeller blades are mutually buckled and are in threaded connection with a support disk, one side of each sector impeller shell is provided with a large impeller blade, and the middle of each sector impeller shell is provided with a window for water to flow through and a small impeller blade. The manufacturing method of thecombined type impeller comprises the following steps of blanking, molding and assembling of the single impeller blades and the support disk. In the aerator manufactured by using the combined type impeller, the middle of the combined type impeller is sequentially connected with an output shaft of a reduction box and a motor, the outer end of a bracket connected with the body of the reduction box is connected with a floater, and the external surface of the motor or the external surfaces of the motor and the reduction box is / are provided with a water shield. The invention has the advantages of simple structure, attractive appearance, low production cost and high aerating capability, and is suitable to being used as the aerator in aquaculture industry and sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of fish farming machinery, that is, an aerator, and in particular relates to a composite impeller, a manufacturing method and an aerator manufactured by the compound impeller. Background technique [0002] The aerator is a life-saving and boosting device for fish and shrimp in aquaculture. Existing mechanical aerators mainly include three types: water wheel type, impeller type and water spray type. Among them, the impeller type aerator is the most widely used, but most of the impellers of the existing impeller type aerators are on the wheel. The blades are welded on the shell, and the support plate is installed in the middle of the wheel shell. There is no window for the water on the wheel shell, so that the water body in the lower part of the wheel shell cannot flow effectively, which affects the oxygen increasing capacity of the aerator, and may make the fish Shrimp stuck in the lower part of the wheel sh...
