Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder-liquid mixing, and particularly relates to a high-viscosity gel mixing rotor structure. Background Art
[0002] Conventional stator-rotor structures can provide shear force and the pumping ability for water mixing, but for high-viscosity materials, such as when the CMC mixing ratio reaches 4%-5%, the material viscosity will reach 100,000 mPas, which is a relatively big challenge for general ones, and an extremely huge challenge for powder-water mixers.
[0003] Currently, the conventional technical solution usually uses a structure in which a rotor pump is connected in series with a powder-water mixer. The rotor pump is responsible for pumping, and the powder-water mixer is responsible for powder dissolution. However, although the combined form can solve the high-viscosity mixing problem, it correspondingly increases the cost, the floor area used, and the energy consumption. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a high-viscosity gel mixing rotor structure, which overcomes the deficiencies of the prior art, is reasonably designed, can spin off the liquid through the inner centrifugal teeth, and can achieve rapid mixing through the high-speed shearing of the shearing teeth; through the outer centrifugal teeth, the shearing of the colloid can be reduced, and the mixed material can be pumped out to increase the pumping ability for high-viscosity colloid.
[0005] To achieve the above purposes, the utility model is realized through the following technical solutions:
[0006] A high-viscosity gel mixing rotor structure includes a disc and a main shaft mounting hole located at the center of the disc. A circle of shearing teeth is arranged concentrically on the side surface of the disc. A number of inner centrifugal teeth are arranged centrally symmetrically on the side surface of the disc. The inner centrifugal teeth are located between the shearing teeth and the main shaft mounting hole; a number of outer centrifugal teeth are evenly arranged centrally symmetrically at the outer edge position of the side surface of the disc. The outer centrifugal teeth are located outside the shearing teeth.
[0007] Preferably, both the inner centrifugal teeth and the outer centrifugal teeth are parabolic or involute structures distributed circumferentially along the center of the disc.
[0008] Preferably, the centrifugal angle of the outer centrifugal teeth is smaller than that of the inner centrifugal teeth.
[0009] Preferably, one end of the inner centrifugal teeth is close to the main shaft mounting hole, and the other end of the inner centrifugal teeth is in contact with the shearing teeth.
[0010] Preferably, one end of the outer centrifugal teeth is close to the shearing teeth, and the other end of the outer centrifugal teeth is located at the outer edge of the disc.
[0011] The utility model provides a high-viscosity gel mixing rotor structure, which has the following beneficial effects: the inner centrifugal teeth are used to spin off the liquid. During the process of liquid spinning off, a negative pressure area is formed on the surface of the disc, and then the powder above the disc can be sucked downward, and then mixed with the liquid and subjected to high-speed shearing by the shearing teeth to crush the powder, so as to achieve rapid mixing; by arranging outer centrifugal teeth at the outer edge position of the disc, the outer centrifugal teeth can reduce the shearing of the colloid and pump out the mixed material, so as to increase the pumping capacity of the high-viscosity colloid; thus, it can adapt to the mixing effect of high-viscosity materials.

[0016] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions in the present utility model with reference to the drawings in the present utility model.
[0017] Embodiment 1, as Figure 1 shown, a high-viscosity gel mixing rotor structure includes a disc 1 and a main shaft mounting hole 2 located at the center of the disc. A circle of shearing teeth 3 is arranged concentrically on the side surface of the disc 1, and a plurality of inner centrifugal teeth 4 are arranged centrally symmetrically on the side surface of the disc 1. The inner centrifugal teeth 4 are located between the shearing teeth 3 and the main shaft mounting hole 2; a plurality of outer centrifugal teeth 5 are arranged centrally symmetrically and evenly at the outer edge position of the side surface of the disc 1, and the outer centrifugal teeth 5 are located outside the shearing teeth 3.
[0018] Working principle:
[0019] In use, first, the inner centrifugal teeth 4 are used to spin off the liquid. During the process of liquid spinning off, a negative pressure area is formed on the surface of the disc 1, and then the powder above the disc 1 can be sucked downward. Subsequently, it is mixed with the liquid and undergoes high-speed shearing by the shearing teeth 3 to crush the powder, thereby achieving rapid mixing. At this time, if the mixture has a large proportion of powder, a highly viscous colloid is formed after the powder is mixed with the liquid. If the external fine teeth are of the same shearing type, the viscosity state of the colloid will be damaged. In this embodiment, by arranging the outer centrifugal teeth 5 at the outer edge position of the disc 1, the outer centrifugal teeth 5 can not only reduce the shearing of the colloid but also pump out the mixed material, so as to increase the pumping capacity for the highly viscous colloid, thereby adapting to the mixing effect of the highly viscous material.
[0020] Embodiment 2, as a further preferred solution of Embodiment 1, both the inner centrifugal teeth 4 and the outer centrifugal teeth 5 are parabolic or involute structures circumferentially distributed along the center of the disc 1. Specifically, one end of the inner centrifugal teeth 4 is close to the main shaft mounting hole 2, and the other end of the inner centrifugal teeth 4 is in contact with the shearing teeth 3. One end of the outer centrifugal teeth 5 is close to the shearing teeth 3, and the other end of the outer centrifugal teeth 5 is located at the outer edge of the disc 1. Thus, during operation, it can ensure that the water pressure and flow rate of the liquid basically remain in the state when it is thrown out, greatly reducing the backflush pressure of the liquid on the inner centrifugal teeth 4 and the outer centrifugal teeth 5. In this embodiment, the centrifugal angle of the outer centrifugal teeth 5 is smaller than that of the inner centrifugal teeth 4. Thus, the liquid can be spun off to the position of the shearing teeth 3 by the inner centrifugal teeth 4, and then through the high centrifugal action of the outer centrifugal teeth 5, the mixed material can be effectively pumped out.
[0021] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the present invention in each embodiment.
