Description

Technical Field

[0001] The utility model relates to the technical field of chemical machinery, in particular to a novel bladeless impeller without shearing effect and a bladeless pump. Background Art

[0002] A bladeless pump is a conveying device that uses a power device to drive a bladeless impeller or rotor in a cavity to rotate at high speed, generating a strong axial suction force to suck the material into the cavity, and does not shear or damage the material in the cavity to the greatest extent. It is a high-performance equipment used for continuous production or cyclic processing of materials.

[0003] The existing impeller of a bladeless pump usually only includes a front disc and a rear disc. In actual use, the head brought by this structure is relatively small and is not suitable for working conditions with large head. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a novel bladeless impeller without shearing effect and a bladeless pump.

[0005] The purpose of the utility model is achieved through the following technical solutions: a novel bladeless impeller without shearing effect, comprising a front end disk and a rear end disk arranged opposite to the front end disk, the front end disk and the rear end disk are connected, a feed through hole is arranged at the center of the front end disk, an axle seat is formed at the center of the rear end disk, an axle hole is arranged at the center of the axle seat, a gap is arranged between the front end disk and the rear end disk; a plurality of convex ribs are arranged on one side of the rear end disk close to the gap.

[0006] Furthermore, the plurality of convex ribs are linear and are arranged at intervals along the diameter of the rear end disc.

[0007] Furthermore, the plurality of convex ribs are arc-shaped and are arranged at intervals along the diameter of the rear end disc.

[0008] Furthermore, each of the plurality of convex ribs is provided with one of a transversely penetrating through hole or a first groove.

[0009] Furthermore, a plurality of the convex ribs are each provided with a second groove penetrating vertically.

[0010] A bladeless pump comprises a pump body and a bladeless impeller connected to the pump body.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model arranges a plurality of convex ribs on the rear end plate, which ensures that the vaneless pump does not shear or damage materials while ensuring the overall lift requirement of the pump. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-6 As shown, a new type of bladeless impeller without shearing effect includes a front end disk 1 and a rear end disk 2 arranged opposite to the front end disk 1, the front end disk 1 and the rear end disk 2 are connected, a feed through hole 3 is arranged at the center of the front end disk 1, a shaft seat 4 is formed at the center of the rear end disk 2, a shaft hole 5 is arranged at the center of the shaft seat 4, a gap 6 is arranged between the front end disk 1 and the rear end disk 2; a plurality of convex ribs 7 are arranged on the side of the rear end disk 2 close to the gap 6.

[0021] like Figure 2 As shown, the plurality of ribs 7 are linear and arranged at intervals along the diameter of the rear end disk 2, and the plurality of ribs 7 are arc-shaped and arranged at intervals along the diameter of the rear end disk 2. It should be noted that in order to further increase the lift of the impeller, as Figure 3-6 As shown, the plurality of ribs 7 are provided with one of the transversely penetrating through holes 8 or the first grooves 12, or the plurality of ribs 7 are provided with the vertically penetrating second grooves 9, and the material obtains a higher lift through the provided ribs 7 and the second grooves 9.

[0022] like Figure 5 As shown, a vaneless pump comprises a pump body 10 and a vaneless impeller 11 connected to the pump body 10. The vaneless pump has a higher head without shearing the material.

[0023] It should be noted that the first groove 9 or the through hole 8 can assist in the mixing of the gas-liquid-solid three-phases, so that the pump is suitable for various working conditions.
