Description

Technical Field

[0001] This invention relates to the field of mixing machine technology, and in particular to a mixing structure and mixing equipment. Background Technology

[0002] Mixers are used to agitate materials. Most current mixers use forced mixing blades driven by a rotating shaft, but forced mixing blades are prone to damage and cause significant wear to the materials.

[0003] Especially for some special materials, if wear occurs during the mixing process, it may lead to chemical reactions between the materials, affecting the quality of the materials.

[0004] Therefore, there is an urgent need for a mixing structure and mixing equipment that can solve the above problems. Summary of the Invention

[0005] To overcome the above problems, the present invention provides a mixing structure and mixing equipment, wherein the first blade and the second blade are arranged on the side wall, which can reduce the wear on the material.

[0006] In a first aspect, this application provides a mixing structure, comprising:

[0007] A mixing tank body, wherein a mixing chamber is provided inside the mixing tank body, a bottom wall is provided at one end of the mixing chamber body, and an opening is provided at the other end, and a side wall is formed between the opening and the bottom wall body; wherein the mixing tank body has a first state of rotating along a first rotation axis, the first rotation axis being the axis between the bottom wall and the opening.

[0014] In some embodiments of this application, the first blade extends continuously from the bottom wall to the opening, the first helical direction and the second helical direction have a first intersection point, and the second blade is provided with a clearance portion at the first intersection point. The clearance portion is used to avoid the first blade so as to define a first interval between the second blade and the first blade.

[0015] In some embodiments of this application, there are multiple first intersection points and multiple avoidance parts, and the avoidance parts are configured in a one-to-one correspondence with the first intersection points.

[0016] In some embodiments of this application, the sidewall has a structure that first expands and then contracts along the direction of the first rotation axis.

[0017] In some embodiments of this application, both the first blade and the second blade are arranged perpendicular to the sidewall.

[0018] Secondly, this application also provides a mixing device, including a driving component and the above-mentioned mixing structure, wherein the driving component is used to drive the mixing structure to rotate along a first rotation axis.

[0019] In some embodiments of this application, the mixing tank of the mixing structure is arranged along a first direction, which is the direction from the bottom wall to the opening. A first angle is provided between the first direction and the horizontal plane, and the first angle is 10°-50°.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. The following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Additionally, terms such as "horizontal," "vertical," and "hanging" do not imply that the component must be absolutely horizontal or hanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] It should be noted that the traditional technology in the mixing machine industry generally adopts horizontal tunnel kiln mixers, horizontal double cone mixers, or vertical shaft mixers. The main principle of most of these machines is to use mixing blades installed on a rotating shaft for forced mixing. In recent years, a few mixing machines have begun to use self-feeding mixing blades similar to those in concrete mixing tanks, which represents a certain improvement in technology, but still has considerable shortcomings.

[0030] In related technologies, the forced mixing blades driven by the rotating shaft of the mixer have problems such as easy blade damage, large wear on both equipment and materials, high power requirements and high energy consumption. The newly emerging self-feeding mixing blade method is also an application of traditional technology in a new field. Although the technology has been improved, it still has problems such as low mixing efficiency and the mixing effect needs to be improved.

[0031] Therefore, this application improves upon the traditional mixing structure and mixing equipment.

[0032] Please see Figure 1 and Figure 2 , Figure 1 A schematic diagram of the mixing structure provided in this embodiment is shown; Figure 2 This embodiment provides the following: Figure 1 A cross-sectional view of plane AA. This embodiment provides a mixing structure, including: a mixing tank 100, a mixing cavity 110 disposed inside the mixing tank 100, a bottom wall 130 disposed at one end of the mixing cavity 110, an opening 140 disposed at the other end, and a side wall 120 formed between the opening 140 and the bottom wall 130; wherein, the mixing tank 100 has a first state of rotating along a first rotation axis, the first rotation axis being the axis between the bottom wall 130 and the opening 140; a first blade 200, the first blade 200 being spirally arranged around the side wall 120 along a first helical direction; and a second blade 300, the second blade 300 being spirally arranged around the side wall 120 along a second helical direction; wherein, the first helical direction is opposite to the second helical direction.

[0033] This application provides a first blade 200 on the side wall 120 along the first spiral direction and a second blade 300 on the side wall 120 along the second spiral direction, with the first spiral direction being opposite to the second spiral direction. On the one hand, this can reduce wear on the material, and on the other hand, after the first blade 200 drives the material to rotate upward, it can slide down along the second blade 300 to form a mixing cycle, which is beneficial to improving the mixing effect.

[0034] Traditional forced-action agitator blades are mounted or welded to the rotating shaft via support arms. The connection points are prone to breakage due to the large driving torque and stress concentration. Furthermore, the small gap between the rotating blades and the stationary tank wall (a larger gap would prevent complete material agitation) leads to significant friction during agitation, sometimes causing material jamming. This results in substantial wear on the blades and tank, and can further crush unwanted granular materials. Furthermore, in conventional self-feeding mixing blade systems, the blades are welded to the inner wall of the mixing tank. As the tank rotates, the spiral blades rotate synchronously. The material inside the tank, driven by the tank and blades, rotates to a higher position and then immediately rolls down the inclined plane of the spiral blades under gravity, achieving a self-feeding mixing effect. While this significantly reduces equipment wear, damage, and material breakage, the tank rotation speed is generally low, and the material rolls down slowly (if the tank rotates too fast, centrifugal force can actually hinder material roll-down). Therefore, this method has the drawback of low mixing efficiency and a longer mixing time. Additionally, because the blades rotate in one direction during traditional mixing (reverse rotation is for unloading), the material mixing effect is not uniform.

[0035] It should be explained that in related technologies, blades are often arranged only along one spiral direction, resulting in low mixing efficiency. However, this application improves mixing efficiency by adding a second blade 300 with the opposite direction to the first blade 200. It can be understood that the first blade 200 is the main blade, and the second blade 300 is the secondary blade. Because the secondary blade has the opposite spiral direction to the main blade, the material rolls down different paths as it rotates upwards and downwards along the blade's slope. Material on the lower blades rolls forward, while material on the upper blades rolls backward, achieving both rotational and forward motion, plus backward motion of material on the secondary blades, forming a localized axial circulation. Furthermore, during the discharge process, the reverse rotation of the tank reverses the direction of this axial circulation, further enhancing the mixing effect during unloading. Overall, this blade structure achieves a layered, multi-directional convection effect, significantly improving mixing efficiency and effectiveness.

[0036] Please refer to the embodiments described in this application. Figure 3 The length of the first blade 200 is greater than the length of the second blade 300.

[0037] In some embodiments of this application, a first blade 200 extends from the bottom wall 130 to the opening 140, and a second blade 300 extends from the bottom wall 130 to a first position, the first position being between the bottom wall 130 and the opening 140.

[0038] In some embodiments of this application, the first position is located at the midpoint between the bottom wall 130 and the opening 140. That is, the length of the secondary blade is half that of the main blade. Since the continuous spiral length of the secondary blade is approximately half that of the main blade, during the discharge process, the secondary blade only has a certain delaying effect on the discharge in the initial stage. Once the main blade at the rear end (especially the can opening section) is completely filled with material, its continuous discharge is no longer delayed. This has been confirmed by simulation and end-user customer tests.

[0039] In some embodiments of this application, the first blade 200 extends continuously from the bottom wall 130 to the opening 140, the first helical direction and the second helical direction have a first intersection point, and the second blade 300 is provided with a clearance portion 310 at the first intersection point. The clearance portion 310 is used to clearance the first blade 200 so as to define a first interval between the second blade 300 and the first blade 200.

[0040] Please refer to the embodiments described in this application. Figure 2 and Figure 4 There are multiple first intersection points and multiple avoidance parts 310, and the avoidance parts 310 are set one-to-one with the first intersection points; this is beneficial to improving the discharge speed.

[0041] In some embodiments of this application, the sidewall 120 has a structure that first expands and then contracts along the direction of the first rotation axis.

[0042] In some embodiments of this application, the first blade 200 and the second blade 300 are both arranged perpendicular to the sidewall 120.

[0043] Furthermore, in order to better implement the mixing structure of this application, this application also provides a mixing device based on the mixing structure, including a driving component and the above-mentioned mixing structure, wherein the driving component is used to drive the mixing structure to rotate along a first rotating axis.

[0044] In some embodiments of this application, the mixing tank 100 of the mixing structure is arranged along a first direction, which is the direction from the bottom wall 130 to the opening 140. A first angle is provided between the first direction and the horizontal plane, and the first angle is 10°-50°.
