Description

Technical Field

[0001] The utility model relates to the technical field of homogenizers, and particularly relates to a rotor structure with increased flow rate. Background Art

[0002] With the increase in business volume, many large cosmetic companies will use larger tanks in newly built factories to meet market demand. The increase in the tank size also poses a challenge to the mixing ability of the homogenizer, which not only needs to meet the homogenization effect but also ensure the conveying flow rate.

[0003] A homogenizer includes a stator and a rotor sleeved in the stator. When droplets and tiny solid particles enter the gap between the stator and the rotor, under the combined action of the mechanical force of the high-speed rotating rotor, the centrifugal force it receives, the extrusion force of the stator, liquid layer friction, impact tearing, and turbulence, the droplets and tiny solid particles are crushed, the particle size becomes smaller, and an emulsion is formed.

[0004] At present, the existing homogenizer stator forms a cylindrical flow channel. The stator is provided with a feed inlet communicating with the flow channel on its upper top surface and several discharge outlets communicating with the flow channel at intervals on its lower side surface. The rotor is rotatably arranged in the flow channel, and the raw material is input from the feed inlet and flows vertically along the flow channel to the rotor. After being homogenized by the rotation of the rotor, it is output from the discharge outlet; however, the raw material flow rate caused by only the cylindrical flow channel is slow, resulting in a low conveying flow rate of the homogenizer. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a rotor structure with increased flow rate, which overcomes the deficiencies of the prior art, is reasonably designed, and can guide the fluid in the pump body housing to leave more smoothly through the reflux block, reducing vortex and backflow phenomena, thereby improving the effective flow of the fluid.

[0006] To achieve the above object, the utility model is realized through the following technical solutions:

[0007] A rotor structure with increased flow rate includes a pump body housing. A rotor is installed in the middle of the inner cavity of the pump body housing. There is a certain distance between the outer edge of the rotor and the inner wall of the pump body housing. The side of the pump body housing is tangentially provided with a discharge outlet. A reflux block is fixedly installed on the inner wall of the pump body housing, and the reflux block is arranged at the tangent point where the discharge outlet is tangent to the pump body housing.

[0008] Preferably, a feed inlet is opened in the middle above the pump body housing.

[0009] Preferably, a number of guide impellers are symmetrically arranged on the surface of the rotor about the center.

[0010] The present utility model provides a rotor structure with increased flow rate. It has the following beneficial effects: By installing a reverse flow block on the inner wall of the pump body housing, there is a certain distance between the outer surface of the reverse flow block and the outer edge of the rotor, and the reverse flow block is located at the tangent point where the discharge port is tangent to the pump body housing, so as to guide the fluid in the pump body housing to leave the impeller on the rotor surface more smoothly through the reverse flow block, reduce the vortex and backflow phenomena, and thus improve the effective flow of the fluid.
