Description

Rotor of powder concentrator

Technical Field

The utility model relates to the technical field of powder selectors, in particular to a rotor of a powder selector.

Background

In the industries of building materials, electric power, coal processing and the like, which relate to material crushing and grinding, a material powder concentrator is an indispensable key device, a rotor is a core part of the powder concentrator and is also an easily damaged part, most of rotors of the existing powder concentrator are of an integral structure, the whole rotor is required to be replaced due to damage of individual blades, the replacement cost of the parts is high, the replacement period is long, and the problems are solved by the rotor of the powder concentrator.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a rotor of a powder concentrator, which overcomes the defects in the prior art.

A rotor of a powder concentrator comprises a main shaft, a rotating cage and blades, wherein a main shaft sleeve is fixed at the lower end of the main shaft, the rotating cage is fixed at the lower end of the main shaft sleeve, a spacer ring is coaxially arranged on the main shaft sleeve and is connected with the main shaft sleeve through a plurality of connecting plates, a plurality of blades are uniformly distributed along the circumference of the spacer ring, and the blades and the spacer ring are detachably connected.

Preferably, the blade comprises a blade main body and a connecting lug, the blade main body is inserted into the through hole in the spacer ring, the lower end of the blade main body is in contact with the extension ring on the rotating cage, the connecting lug is arranged on each of two sides of the upper end of each blade main body, and the connecting lugs are connected with the spacer ring through screws.

Preferably, the extension ring is provided with grooves which are matched with the lower ends of the blade main bodies one by one.

The utility model has the following advantages:

when the blade replacement device is used, each blade is connected with the spacer ring through the two connecting lugs on the blade, so that the blade can be replaced independently, the whole rotor does not need to be replaced when the blade is damaged, the replacement cost is saved, and the replacement time is shortened.

Detailed Description

The following detailed description of the embodiments of the present invention will be given in order to provide those skilled in the art with a more complete, accurate and thorough understanding of the concept and technical solution of the present invention.

As shown in fig. 1-4, the utility model provides a powder concentrator rotor, which comprises a main shaft 1, a rotating cage 3 and blades 5, wherein a main shaft sleeve 2 is fixed at the lower end of the main shaft 1, the rotating cage 3 is fixed at the lower end of the main shaft sleeve 2, a spacer ring 4 is coaxially arranged on the main shaft sleeve 2, the spacer ring 4 is connected with the main shaft sleeve 2 through a plurality of connecting plates 41, a plurality of blades 5 are uniformly distributed along the circumference of the spacer ring 4, and the blades 5 are detachably connected with the spacer ring 4.

It should be noted that the blade 5 includes a blade main body 51 and a connection lug 52, the blade main body 51 is inserted into the through hole 42 on the spacer ring 4, and the lower end of the blade main body 51 contacts with the extension ring 31 on the rotating cage 3, the connection lug 52 is disposed on both sides of the upper end of each blade main body 51, and the connection lug 52 is connected with the spacer ring 4 through a screw, so that the blade 5 is conveniently detached from the spacer ring 4.

In addition, the extension ring 31 is provided with grooves 311 which are matched with the lower ends of the blade bodies 51 one by one, and the upper end and the lower end of the blade bodies 51 are limited by the through holes 42 on the spacer ring 4 and the grooves 311 of the extension ring 31.

In summary, in the present invention, each blade 5 is connected to the spacer ring 4 through the two connecting lugs 52 thereon, so that the blade 5 can be independently replaced without replacing the whole rotor when the blade 5 is damaged, thereby saving the replacement cost and reducing the replacement time.

The utility model is described above with reference to the accompanying drawings, it is obvious that the utility model is not limited to the above embodiments, and it is within the scope of the utility model to use the concept and technical solution of the utility model in various insubstantial modifications, or to apply the concept and technical solution of the utility model directly to other fields without modification.
