Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dispersers, and particularly relates to a high-speed disperser and a rotor structure thereof. Background Art
[0002] The existing high-speed disperser is a kind of mixer in a broad sense. Since the agitator of the high-speed disperser (such as a disc sawtooth agitator) can form a strong turbulence locally, it usually has a strong dispersing and emulsifying effect on the material, so this type of high-speed mixer is also called a disperser. In the processing of industrial raw materials, the powder mixing process is indispensable. In order to obtain uniform and refined slurry, the industry usually chooses a high-efficiency pulping system, and the rotor impeller and stator are the core components of high-efficiency pulping. Their structure is the key to determining whether the material can be mixed evenly.
[0003] The rotor of the existing disperser adopts a multi-layer structure, which can efficiently guide and disperse the material. However, since the shear grooves on the inner and outer rings are aligned, the appropriate spacing between the shear grooves on the inner ring is too large for the outer ring. In this way, the outer ring with the highest shearing efficiency cannot achieve the best shearing efficiency because the shear grooves are relatively sparse.
[0004] Therefore, how to improve the shearing efficiency of the rotor of the disperser and ensure the quality of the material is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0039] The core of the utility model is to provide a high-speed disperser and a rotor structure thereof, which can effectively improve the shearing efficiency of the rotor of the disperser and ensure the quality of the material.
[0040] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0041] Specifically, please refer to Figure 1-Figure 5 , Figure 1 A schematic diagram of the rotor structure of a high-speed disperser provided in an embodiment of the utility model; Figure 2 A cross-sectional view of a rotor structure of a high-speed disperser provided in an embodiment of the utility model; Figure 3 A top view of a rotor structure of a high-speed disperser provided in an embodiment of the utility model; Figure 4 A side view of a rotor structure of a high-speed disperser provided in an embodiment of the utility model (without a circular hole); Figure 5 A side view of a rotor structure of a high-speed disperser provided in an embodiment of the utility model (with a circular hole).
[0042] The utility model provides a rotor structure 1 of a high-speed disperser, comprising: a rotating disk 101 and an inner ring 102, a middle ring 103 and an outer ring 104 which are arranged in sequence from the inside to the outside.
[0043] The rotating disk 101 is provided with a shaft mounting hole for connecting with the rotating shaft. The rotating shaft mounting hole is tightly connected with the rotating shaft, and the rotor structure 1 can be driven to rotate at a high speed. The vicinity of the rotating shaft mounting hole on the rotating disk 101 does not participate in the dispersion shearing process, and mainly plays the role of providing centrifugal force and transmitting power to the blades, so it is basically not affected by the impact of materials with large kinetic energy to cause cavitation and corrosion.
[0044] The inner ring 102, the middle ring 103 and the outer ring 104 are equivalent to the blades of the rotor structure 1. The inner ring 102, the middle ring 103 and the outer ring 104 are all annular walls with the shaft mounting hole as the axis. The inner ring 102, the middle ring 103 and the outer ring 104 are all provided with a plurality of shear grooves 105. The number of shear grooves 105 on the outer ring 104 is greater than the number of shear grooves 105 on the middle ring 103 or the inner ring 102. In particular, the number of shear grooves 105 on the outer ring 104 is greater than the number of shear grooves 105 on the inner ring 102, so that the shear effect on the outer ring 104 can be maximized.
[0045] It should be noted that, based on the existing technology, the present application greatly increases the shearing efficiency, reduces heat generation, ensures the quality of the slurry, reduces the wear of the rotor assembly, and thus improves the overall life span, which has a positive significance for cost control.
[0046] The utility model provides a rotor structure 1 of a high-speed disperser, wherein the rotor structure 1 is provided with an inner ring 102, a middle ring 103 and an outer ring 104 from the inside to the outside, and a plurality of shear grooves 105 are distributed on the three layers of annular walls. By increasing the number of shear grooves 105 on the outer ring 104 and improving the arrangement density of the shear grooves 105, a material mixing channel is increased, thereby increasing shear efficiency, reducing heat, improving mixing uniformity, and ultimately ensuring the quality of the material.
[0047] In a specific embodiment, the plurality of shear grooves 105 on the inner ring 102, the middle ring 103 and the outer ring 104 are arranged at the edge or away from the edge. When the plurality of shear grooves 105 on the inner ring 102, the middle ring 103 and the outer ring 104 are arranged at the edge, a continuous tooth-like structure can be formed at the edge of the annular wall. When the plurality of shear grooves 105 on the inner ring 102, the middle ring 103 and the outer ring 104 are arranged away from the edge, a through groove opened on the annular wall can be formed.
[0048] The through grooves may be strip-shaped grooves or grooves of other shapes, which are not further limited herein.
[0049] In a specific embodiment, Figure 1 and Figure 5 As shown, a plurality of circular holes 106 are also provided on the outer ring 104. In addition to a plurality of shearing grooves 105 arranged on the outermost outer ring 104, a plurality of circular holes 106 can be evenly arranged between the groove holes of the shearing grooves 105, which can further increase the material mixing channel, increase the shearing area of the material, and greatly increase the shearing efficiency without changing the linear speed.
[0050] On the basis of the above specific embodiment, the turntable 101 is provided with a sleeve at the outer edge of the shaft mounting hole, and the center hole of the sleeve is connected to the shaft mounting hole and has the same size. The size refers to the shape, diameter and position, that is, the center hole and the shaft mounting hole in the axial direction coincide with each other. The sleeve and the center hole are equivalent to the shaft mounting part, which can enable the rotor to rotate stably by being tightly connected with the shaft. The shaft connecting part is tightly connected with the shaft, so that the rotor can rotate in the housing.
[0051] In order to further improve the stability of the connection, the sleeve and the rotating disk 101 are integrally formed. Of course, the inner ring 102, the middle ring 103, the outer ring 104 and the rotating shaft can also be integrally formed, such as by stamping or casting.
[0052] In a specific embodiment, the plurality of shear grooves 105 on the inner ring 102 , the middle ring 103 , and the outer ring 104 are evenly distributed.
[0053] In particular, when the shear grooves 105 between the inner ring 102, the middle ring 103 and the outer ring 104 are staggered, the shear grooves 105 of the inner ring 102, the middle ring 103 and the outer ring 104 are not completely opposite, and the material in each annular ring needs to be staggered at a certain angle in the circumferential direction before entering the next outer ring.
[0054] When the shear grooves 105 between the inner ring 102 , the middle ring 103 and the outer ring 104 are completely aligned, the shear grooves 105 on the multiple layers of annular rings are interconnected, and the material can be directly sheared and discharged from the shear grooves 105 .
[0055] In a specific embodiment, the inner ring 102 , the middle ring 103 and the outer ring 104 are all located on the same side of the rotating disk 101 .
[0056] Of course, it can also be Figure 2 In the structure shown, the inner ring 102 , the middle ring 103 and the outer ring 104 are located on both sides of the turntable 101 .
[0057] In addition, the utility model also provides a high-speed disperser, including the rotor structure 1 of the high-speed disperser in the above specific embodiment.
[0058] Obviously, the high-speed disperser having the rotor structure 1 of the high-speed disperser described above has the same beneficial effects, which will not be further described here.
[0059] This solution also includes a shell, a stator, a rotating shaft and a driving mechanism. The upper part of the shell is provided with a feed port, the lower part is provided with a discharge port, the stator is fixed inside the shell, the rotor structure 1 is arranged inside the stator, the movable end of the driving mechanism is connected to the rotating shaft, and the rotating shaft is connected to the rotating shaft mounting hole of the rotor structure 1.
[0060] The driving mechanism drives the rotating shaft to rotate, and the rotating shaft drives the rotor structure 1 to rotate relative to the shell and the stator fixed on the shell. The material enters from the feed port on the upper part of the shell and enters the dispersion shearing chamber where the rotor structure 1 is located. The sheared and dispersed material is discharged from the discharge port of the shell to obtain the sheared and dispersed material.
