Description

Technical Field

[0001] The invention belongs to the technical field of centrifuge distribution chambers, and in particular relates to a centrifuge rotor distribution chamber arrangement. Background Art

[0002] The rotor material distribution cavity design currently used has a flat end surface. In actual operation, the material is fed into the material distribution cavity by the power of the pump. When the material first contacts the flat end surface of the material distribution cavity, a direct impact occurs, and then the material spreads around along the end surface and gradually fills the entire cavity space. However, as subsequent materials continue to be injected, these newly entered materials will have a significant impact on the materials already in the material distribution cavity.

[0003] This mutual impact between materials not only leads to a decrease in the original speed of the materials, but also makes the flow of materials in the distribution cavity complicated and irregular. Specifically, the impact will break the original stable flow state of the materials and cause turbulence. The turbulence not only makes the distribution of materials in the distribution cavity uneven, but also may cause mixing and doping between materials, which seriously affects the classification effect of the materials.

[0004] In addition, the turbulence phenomenon will increase the energy consumption of the system, because in order to overcome the resistance caused by the turbulence, the pump needs to provide more power to push the material flow. This not only reduces the efficiency of the entire system, but also increases the operating cost.

[0005] In order to solve the existing problems, we propose a centrifuge rotor distribution cavity arrangement. Summary of the invention

[0006] The object of the present invention is to provide a centrifuge rotor material distribution cavity arrangement to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A centrifuge rotor material distribution cavity arrangement includes a feed pipe, a material distribution cavity, a material discharge hole and a disc body, wherein the disc body is arranged at the end of the material distribution cavity; the disc body includes

[0009] Chassis;

[0010] A rotor fixedly connected to the chassis, the rotor is located on one side of the chassis, and the rotor includes a column, a plurality of first blades and a second blade each fixedly connected to the column;

[0011] The column is fixedly connected to the chassis; the end surface of the first blade has an arc, and the arc is in the same direction as the rotation direction of the rotor; the second blade is smaller than the first blade, and is arranged between adjacent first blades.

[0012] Preferably, the first blades are symmetrically arranged around the cylinder.

[0013] Preferably, one side of the first blade is provided with n slopes, and the curved side of the first blade is opposite to the corresponding second blade.

[0014] Preferably, an inner angle between a surface of the first blade away from the slope and the chassis is an obtuse angle.

[0015] Preferably, n≥2.

[0016] Preferably, the column is a cone, the cone surface is opposite to the material distribution cavity, the second blade is lower than the first blade, and there is a gap between the second blade and the first blade to form a material distribution cone.

[0017] Preferably, the material distribution cavity comprises a first cavity, a second cavity and a third cavity which are interconnected in sequence, and the disc is arranged at the bottom of the third cavity.

[0018] Preferably, the feed pipe is slidably connected to the first cavity, the second cavity is trumpet-shaped, and the discharge hole is arranged on the outer wall of the third cavity.

[0019] Preferably, the length ratio of the first blade to the second blade is 1 / 3-1 / 2.

[0020] Preferably, the disc body is coated with a tungsten carbide coating.

[0021] The disc body designed in the present invention includes a chassis, a first blade, and a second blade. The chassis cooperates with the blades to form a centrifugal pump to divert the material entering the distribution chamber through the feed pipe through the dividing cone and then enter the first blade and the second blade, thereby reducing turbulence. The material is accelerated in the first blade and the second blade and thrown into the separation chamber.

[0022] In the present invention, there is an obtuse angle between the first blade and the bottom plate away from the sloped side. During the rotation process, the angle generates suction to attract and accelerate the material, thereby speeding up the entry and exit of the material and improving the material processing capacity and efficiency.

[0023] The surface of the disc is sprayed with tungsten carbide wear-resistant coating to increase the wear resistance of the blades and extend their service life.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the rotor distribution cavity drives the material to form a vortex and accelerates the material output, so that the material is mixed with the existing material in the chamber at a higher initial velocity, reducing the energy consumption required for secondary acceleration of the material, and has the function of saving energy and improving the separation effect; in addition, the blade surface is sprayed with tungsten carbide coating to increase the overall wear resistance and extend the service life.
