Abstract
Description
Technical Field
[0001] The present application relates to a high-viscosity material kneading technology, and in particular to a multi-axis grinding and kneading device. Background Art
[0002] Kneading machine is a kind of mixing machine for mixing and grinding high-viscosity materials. It mixes and grinds the materials in the equipment tank in circumferential and radial directions through the rotation of its stirring paddle, so that the materials meet certain process requirements. Due to the high mixing intensity and high efficiency of the equipment, it is increasingly widely used in chemical, food, medicine, plastic, dye, ink, carbon, optoelectronic materials and other industries. The kneading machine paddle uses its own structural characteristics to enhance the strength of the stretching and folding effect on the material, thereby promoting convection of the material components. ∑-type or Z-type stirring paddle is the main form of domestic kneading machine. It is generally a twisted long rectangle with the characteristics of high strength and low kneading noise. Although the ∑-type or Z-type stirring paddle will not have a dead angle of flow when rotating due to its overall streamlined design, the flow field of the mixing kettle is a laminar flow field at this time. Since the fluid has the characteristics of streamline invariance, poor time-varying, and non-intersecting particle motion trajectories, it is not conducive to the stretching, shearing and folding effects of the material components, so the material mixing homogenization effect is poor.

[0031] Example: Figure 1-7As shown, the arrows in the figure indicate the flow direction of the fluid. A multi-axis grinding and kneading device includes a shell 10 and a power mechanism 20. The shell 10 is provided with an inlet 11 and an outlet 12. The shell 10 is provided with a cavity 30. The inlet 11 and the outlet 12 are both connected to the interior of the cavity 30. The cavity 30 includes at least two chambers with overlapping areas. Each of the chambers is provided with a rotating shaft assembly 40. The interior of the rotating shaft assembly 40 has a cavity, and the rotating shaft assembly 40 is provided with a temperature control material inlet 44 and a temperature control material outlet 45. The temperature control material inlet 44 and the temperature control material outlet 45 are both connected to the cavity. A kneading assembly 50 is fixedly provided on the rotating shaft assembly 40. The power mechanism 20 is connected to the rotating shaft assembly 40. When the rotating shaft assembly 40 rotates under the action of the power mechanism 20, the kneading assembly 50 can rotate in the overlapping area. Among them, at least two chambers with overlapping areas refer to two chambers intersecting to form a common overlapping area. During operation, the material to be kneaded enters the cavity 30 through the feed port 11, the temperature control substance 46 enters the cavity inside the rotating shaft assembly 40 through the control substance inlet 44, and the kneading assembly 50 rotates under the action of the rotating shaft assembly to stir and knead the material. In the present application, since different chambers have overlapping areas, the materials in different chambers can quickly exchange, collide and mix in the overlapping areas, so that the materials can be circulated multiple times in the cavity 30, thereby achieving the purpose of mixing, homogenizing, grinding and kneading; since the kneading assembly 50 can knead in a small range in the overlapping area, the kneading assembly 50 can clean each other, so that the kneading assembly 50 has good self-cleaning performance. The rotating shaft assembly is set as a hollow structure, and the temperature control substance 46 enters the cavity inside the rotating shaft assembly 40 to cool the rotating shaft assembly 40, thereby effectively preventing the occurrence of material adhesion due to the thermal effect generated on the surface due to the collision and wear between the rotating shaft assembly 40 and the material.
[0032] like Figure 1 and Figure 7 As shown, there is a gap 13 between the inner wall of the shell 10 and the outer wall of the cavity 30, and the gap 13 is connected to the cavity of the rotating shaft assembly 40. That is, a discharge hole is provided on the rotating shaft assembly, and the discharge hole is opened at the position of the rotating shaft assembly 40 located in the gap 13, so that the temperature control material 46 can enter the gap 13 between the inner wall of the shell 10 and the outer wall of the cavity 30 through the discharge hole, cool the cavity, increase the heat exchange area in the cavity, and improve the heat exchange effect.
[0033] like Figure 2As shown, the kneading assemblies 50 on two adjacent rotating shaft assemblies 40 are arranged in a staggered manner, and the number of kneading assemblies 50 on two adjacent rotating shaft assemblies 40 is different. This can minimize the flow dead zone in the cavity and improve the kneading and grinding effect of the material.
[0034] like Figure 5 and Figure 7 As shown, the kneading assembly 50 includes a kneading rod 51 and a kneading arm 52, wherein the first end of the kneading rod 51 is fixedly connected to the rotating shaft assembly 40, and the second end of the kneading rod 51 is fixedly connected to the kneading arm 52. Optionally, the kneading rod 51 and the kneading arm 52 are arranged vertically, and the kneading assembly 50 is a T-shaped structure as a whole.
[0035] like Figure 5 As shown, the longitudinal dimension of the kneading arm 52 is defined as a, and the transverse dimension is defined as b, and the ratio of a to b is 1:(2-5). Figure 7 As shown, the distance between the kneading arm 52 and the inner wall of the cavity 30 is H, H≤15mm. Driven by the rotating shaft assembly 40, the kneading assembly 50 rotates at a high speed, and a small flow cycle with high flow rate and high shear is formed between the kneading rod 51 and the kneading arm 52, as well as a large flow cycle with the overall flow in the cavity, thereby forming a chaotic zone of laminar flow-turbulent flow, accelerating the material exchange in each chamber and enhancing the mixing effect; the appropriate longitudinal dimension of the kneading arm 52 can provide a larger radial flow area. The distance between the kneading arm 52 and the inner wall of the cavity 30 refers to the closest distance between the kneading arm 52 closest to the cavity 30 and the inner wall of the cavity 30. The distance between the kneading arm 52 and the inner wall of the cavity 30 is controlled within 15mm. If the gap is too large, the inner wall of the cavity is prone to accumulate too thick material. When the kneading assembly is driven to rotate, due to the buffering effect of the material, the shearing and grinding force of the material layer is poor, thereby affecting the kneading effect and heat transfer effect.
[0036] like Figure 1 As shown, the temperature control substance outlet 45 is located at the first end of the rotating shaft assembly 40, and the first end of the rotating shaft assembly 40 is close to the power mechanism 20, and the temperature control substance inlet 44 is located at the second end of the rotating shaft assembly 40, and the second end of the rotating shaft assembly 40 is far away from the power mechanism 20. Figure 7 As shown, the temperature-controlling substance 46 flows from the temperature-controlling substance inlet 44 into the cavity of the rotating shaft assembly 40 and enters into the gap 13 between the inner wall of the shell 10 and the outer wall of the cavity 30 through the discharge hole. The temperature-controlling substance after absorbing heat flows out from the temperature-controlling substance outlet 45, that is, the cavity of the rotating shaft assembly 40 and the gap between the shell 10 and the cavity 30 are all filled with the temperature-controlling substance 46, thereby increasing the heat exchange area in the cavity 30 and effectively preventing the occurrence of material adhesion due to the thermal effect generated on the surface due to the collision and wear between the rotating shaft assembly and the material.
[0037] In a possible implementation, Figure 4 As shown, the chamber includes a first chamber 31, a second chamber 32 and a third chamber 33 arranged in sequence, the second chamber 32 and the first chamber 31 have an overlapping area, the second chamber 32 and the third chamber 33 have an overlapping area, the rotating shaft assembly 40 includes a first rotating shaft 41, a second rotating shaft 42 and a third rotating shaft 43, the first rotating shaft 41 is located in the first chamber 31, the second rotating shaft 42 is located in the second chamber 32, and the third rotating shaft 43 is located in the third chamber 33. In this embodiment, the second chamber 32 and the first chamber 31, the second chamber 32 and the third chamber 33 all form overlapping areas, that is, the cross section of the second chamber 32 intersects with the first chamber 31 and the third chamber 33 respectively, the kneading assembly 50 is fixed on the rotating shaft assembly 40, and the kneading assemblies 50 on two adjacent rotating shaft assemblies 40 are staggered.
[0038] Among them, the overlapping areas formed by the two sides of the second chamber 32 and the first chamber 31 and the third chamber 33 respectively are the key areas for achieving the purpose of mixing and homogenization. The kneading components 50 on the rotating shaft assembly 40 are staggered to minimize the flow dead zone in the cavity. The second chamber 32 can quickly and effectively exchange, collide and mix the materials in the first chamber 31 and the third chamber 33, so that the materials can be circulated multiple times in the cavity; in addition, the kneading components 50 are closely arranged on the rotating shaft assembly 40, and the small-scale kneading action in the overlapping area can make the kneading components 50 clean each other, so that the kneading components 50 have good self-cleaning function.
[0039] Optionally, the first rotating shaft 41, the second rotating shaft 42 and the third rotating shaft 43 are on the same horizontal plane and are all driven to rotate by the power mechanism 20, and the kneading components 50 on two adjacent rotating shaft components 40 are arranged in a staggered manner, such as Figure 2 As shown, the kneading components 50 on the second rotating shaft 42 are arranged alternately with the kneading components 50 on the first rotating shaft 41, and the kneading components 50 on the second rotating shaft 42 and the kneading components 50 on the third rotating shaft 43 are also arranged alternately, that is, the kneading components 50 on two adjacent rotating shaft components 40 extend into each other's internal areas to provide a kneading effect for the material.
[0040] Optionally, the number of kneading components 50 on the first rotating shaft 41 is d1, the number of kneading components 50 on the second rotating shaft 42 is d2, the number of kneading components on the third rotating shaft 43 is d3, the rotational speed of the first rotating shaft 41 is V1, the rotational speed of the second rotating shaft 42 is V2, and the rotational speed of the third rotating shaft 43 is V3, wherein d1=d3<d2, V1=V3<V2.
[0041] Optionally, d1:d2:d3 is 1:(2-4):1, and V1:V3:V2 is 1:(1.5-4):1. The second chamber 32 forms a differential speed with the first chamber 31 and the third chamber 33, respectively, so that the material exchange rate in each chamber is improved and the residue after mixing can be minimized, thereby achieving the effect of rapid mixing and homogenization.
[0042] like Figure 2 and Figure 3 As shown, the second rotating shaft 42 forms a reverse differential with the first rotating shaft 41 and the third rotating shaft 43 respectively, and the convection is significantly enhanced. A small flow cycle with high flow rate and high shear is formed between the kneading rod 51 and the kneading arm 52, and a large flow cycle of the overall flow in the cavity forms a laminar-turbulent chaotic zone, which accelerates the material exchange in each chamber and enhances the mixing effect.
[0043] like Figure 4 As shown, the first chamber 31, the second chamber 32 and the third chamber 33 are all cylindrical structures. The first chamber 31 is coaxially arranged with the first rotating shaft 41, the second chamber 32 is coaxially arranged with the second rotating shaft 42, and the third chamber 33 is coaxially arranged with the third rotating shaft 43. Figure 6 As shown, the inner wall of the second chamber 32 is provided with grinding lines 34. Optionally, the grinding lines 34 are dot-shaped protrusions, and the grinding lines 34 are spirally arranged around the circumference of the second chamber 32. The inner wall of the second chamber 32 is provided with a plurality of parallel grinding lines 34, and the terminal speed of the kneading assembly 50 is relatively high in the overlapping area. The grinding lines provided on the inner surface of the second chamber 32 can produce high-frequency collisions with small particles in the material, thereby enhancing the degree of crushing of small particles in the material.
[0044] like Figure 1 As shown, the power mechanism 20 includes a motor 21 and a transmission 22 electrically connected to the motor 21 . The motor 21 drives the rotating shaft assembly 40 to rotate, and the transmission 22 can control the rotation speed of the rotating shaft assembly 40 .
[0045] The operating principle of the kneading device in this application is as follows:
[0046] The rotating shaft assembly 40 starts to run under the drive of the motor 21, and the temperature control substance 46 enters the cavity of the rotating shaft assembly 40 and the gap 13 between the shell 10 and the cavity 30 from the temperature control substance inlet 44;
[0047] As the initial materials such as pigment particles, solvents, and resins enter the cavity 30 through the feed port 11, initial mixing begins by the rotation of the rotating shaft assembly 40. At this time, the kneading assembly 50 rotates under the drive of the rotating shaft assembly 40, and a small flow cycle with high flow rate and high shear is formed between the kneading rod 51 and the kneading arm 52, which forms a laminar-turbulent chaotic zone with the overall flow cycle in the cavity, accelerating the material exchange in each cavity and enhancing the mixing effect; wherein, 4 groups of kneading assemblies 50 are provided on the first rotating shaft 41 and the third rotating shaft 43, and 8 groups of kneading assemblies 50 are provided on the second rotating shaft 42, and the ratio of the longitudinal dimension a to the transverse dimension b of the kneading arm 52 is 1:3, and the longitudinal dimension a of the kneading arm 52 provides a larger radial flow area for the kneading assembly 50;
[0048] The kneading components 50 are closely arranged in the overlapping area, and the kneading effect in a small range can make the kneading components 50 clean each other, so that the kneading components 50 have good self-cleaning performance. The distance H between the kneading components 50 and the inner wall of the cavity is about 10 mm. The rotation speed of the first rotating shaft 41 and the third rotating shaft 43 is 35 r / min, and the rotation speed of the second rotating shaft 42 is 75 r / min.
[0049] After the initial mixing, the materials react during the kneading process and release a large amount of heat. The gap 13 inside the rotating shaft assembly 40 and between the shell 10 and the cavity 30 can be used to introduce the temperature control material 46 to achieve a better temperature control effect. The temperature control material inlet 44 is located on the side away from the motor 21, and the temperature control material outlet 45 is located on the side close to the motor 21. When the operation is completed, the temperature control material 46 flows out from the temperature control material outlet 45, and the kneaded material is discharged from the discharge port 12.
[0050] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these modifications and improvements are all within the scope of protection of the present application.
