Description

Technical Field

[0001] This utility model belongs to the field of mixer technology, and in particular relates to a mixer with a novel mixing device. Background Technology

[0002] In industrial production, mixers are a commonly used mixing device, widely applied for the mixing and dispersion of various materials. Traditional mixers typically employ paddle, ribbon, and blade agitators as their core mixing tools. These agitators are efficient in handling conventional materials and can meet the mixing requirements of most low-viscosity or granular materials. However, when dealing with highly viscoelastic materials and fibrous materials, the mixing performance and dispersion effect of these traditional agitators are often unsatisfactory.

[0003] Specifically, experiments show that when using paddle, ribbon, or blade agitators to disperse highly viscoelastic materials, especially fibrous materials at high speeds, although initial dispersion may be achieved in a short time, the materials often re-agglomerate and lose their dispersed state within an hour after agitation stops. This agglomeration significantly reduces the uniformity and stability of the material mixture, directly affecting the quality of subsequent processing. Furthermore, traditional agitators are less efficient at dispersing fibrous materials, making it difficult to effectively achieve uniform dispersion and arrangement of fibers, thus limiting their application in demanding mixing processes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mixer with a novel mixing device, which solves the problems that current mixers with traditional mixing devices easily lose their dispersion state, have low mixing uniformity and stability when applied to highly viscoelastic materials and fibrous materials.

[0005] This utility model provides a mixer with a novel stirring device, comprising:

[0006] Body

[0007] The mixing drum is mounted on the machine body, and a self-rotating motor mounted on the machine body drives the mixing drum to rotate.

[0008] The lid is hinged to the machine body and seals the opening at the top of the mixing tank.

[0009] A transmission base is mounted on the bucket lid and a transmission shaft is rotatably mounted thereon. The transmission shaft is connected to the stirring motor mounted on the bucket lid.

[0010] A stirring device, located inside the mixing tank and connected to a drive shaft, is used to rotate under the drive of a stirring motor and to stir the materials inside the mixing tank.

[0011] The stirring device includes:

[0012] The top end of the stirring shaft is fixed to a clamp set at the bottom end of the drive shaft;

[0013] The blade assembly is coaxially mounted on the stirring shaft and multiple sets are spaced apart along its axial direction. The blade assembly has multiple stirring blades arranged in a circumference and radially. The stirring blades are provided with serrations on both sides in the horizontal direction. Multiple serrations are continuously arranged from one end of the stirring blade to the other end. When the stirring device rotates, the stirring blades with multiple serrations on the blade assembly comb and cut the material.

[0014] In some embodiments, the outer edges of multiple blade assemblies are staggered along the axial direction.

[0015] In some embodiments, the multiple stirring blades in the blade assembly are arranged at equal angles, and the stirring blades of adjacent blade assemblies are staggered in the axial direction.

[0016] In some embodiments, the inner end of the stirring blade is fixedly connected to the stirring shaft, and the outer end face of the stirring blade is equipped with serrations.

[0017] In some embodiments, the stirring blades are strip-shaped and are all horizontally arranged.

[0018] In some embodiments, the body includes:

[0019] The base has support plates on both sides;

[0020] The platform is hinged between two support plates, and the mixing tank, tank cover and self-rotating motor are all mounted on the platform;

[0021] The positioning adjustment pin passes through the outer positioning hole set in the support plate and the inner positioning hole set in the base. Multiple outer positioning holes are set at intervals along the same arc coaxial with the hinge point.

[0022] In some embodiments, the top surface of the front part of the support plate is a downwardly inclined support surface, the platform has a platform, the mixing tank and the tank cover are both located on the upper side of the platform, and the self-rotating motor is located on the lower side of the platform.

[0023] When the platform is horizontal, its rear part rests against the top surface of the rear part of the support plate;

[0024] When the front part of the platform is attached to the support surface, the positioning adjustment pin is inserted into an external positioning hole at the rear end.

[0025] In some embodiments, the rear of the lid is hinged, and the stirring device is located at the rear of the interior space of the mixing tank.

[0026] In some embodiments, the machine body has a protective cover, the mixing tank is located inside the protective cover, and the tank lid is hinged to the protective cover;

A spring pin installed on the outer wall of the protective cover extends into and is inserted into the locking hole. The other end of the locking plate is equipped with a handle.

[0028] In some embodiments, a limiting support plate is horizontally provided on the locking plate, and when the spring pin is inserted into the locking hole, the limiting support plate is attached downward to the end face of the top of the protective cover.

[0029] Compared with the prior art, the beneficial effects of this application are as follows: In the embodiment of this utility model, the blade assembly of the stirring device is composed of multiple stirring blades with serrations. When rotating, it not only stirs and cuts the material, but the serrations continuously arranged on the stirring blades form a comb structure, which can comb and disperse fibrous materials, maintain their dispersed state, and form gaps to mix in other components in the material, thereby improving the mixing uniformity and stability. This solves the problem that the current mixers with traditional stirring devices are prone to losing their dispersed state and have low mixing uniformity and stability when applied to highly viscoelastic materials and fibrous materials.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] like Figure 1 As shown in the schematic embodiment of a mixer with a novel stirring device according to the present invention, the mixer includes a machine body 1, a stirring tank 2, a tank cover 3, a transmission seat 4, and a stirring device 5.

[0046] The mixing tank 2 is rotatably mounted on the machine body 1 and is driven by the self-rotating motor 8 mounted on the machine body 1. The tank lid 3 is hinged to the machine body 1 and covers the opening at the top of the mixing tank 2. The transmission seat 4 is mounted on the tank lid 3, located above the mixing tank 2, and has a rotatably mounted transmission shaft 41. The stirring motor (not shown in the attached drawing) mounted on the tank lid 3 is driven by the transmission shaft 41. The stirring device 5 is located inside the mixing tank 2, and its top is connected to the transmission shaft 41.

[0047] Due to the hinged connection, the top-opening lid 3 opens the opening of the mixing tank 2, allowing materials to be poured into the mixing tank 2. The bottom-opening lid 3 closes the opening of the mixing tank 2, and the stirring device 5 falls into the mixing tank 2. The self-rotating motor and the stirring motor are turned on, and they drive the mixing tank 2 and the stirring device 5 to rotate respectively. The rotating stirring device 5 agitates the materials in the mixing tank 2. The rotation of the mixing tank 2 causes the stirring device 5 to rotate relative to it, rotating and agitating various positions in the circumferential direction inside the mixing tank 2, so that the materials are fully mixed.

[0048] The transmission connection between the self-rotating motor and the mixing tank 2, and the transmission connection between the mixing motor and the transmission shaft 41, can be achieved through existing mechanical transmission structures such as gear transmission mechanism, belt transmission mechanism, and chain transmission mechanism. The transmission connection between the self-rotating motor and the mixing motor and the mixing tank 2 and the transmission shaft 41 and the driving of their rotation is existing technology and is not the point of invention of this application.

[0049] like Figures 2 to 4 As shown, the stirring device 5 includes a stirring shaft 51 and a blade assembly 52. ​​The top end of the stirring shaft 51 is fixed to a clamp provided at the bottom end of the transmission shaft 41, thus coaxially connecting the two. The blade assembly 52 is coaxially mounted on the stirring shaft 51, and multiple sets are arranged at intervals along its axial direction. The blade assembly 52 has multiple stirring blades 501 arranged radially around the circumference. Each stirring blade 501 has serrations 502 on both sides in the horizontal direction, and multiple serrations 502 are continuously arranged from one end of the stirring blade 501 to the other end.

[0050] Since the stirring shaft 51 is coaxial with the blade assembly 52, that is, the stirring shaft 51 is located at the center of the plane where the blade assembly 52 is located and is perpendicular to the agglomeration assembly, the transmission shaft 41, which is driven by the stirring motor, drives the stirring shaft 51, which is fixedly connected to it, to rotate, thereby causing the blade assembly 52 to rotate accordingly. Multiple rotating agitator blades 501 in the blade assembly 52 agitate and cut the material. Since the agitator blades 501 are radially arranged on the agitator shaft 51, their edges face and cut into the material when rotating in the forward or reverse direction. Both edges have continuously arranged serrations 502. During the rotational cutting process, the serrations 502 can more easily cut the material. Since the serrations 502 are isosceles triangles, the continuously arranged serrations 502 form a comb structure. During rotation, the tips of the comb teeth will penetrate into the fibrous material and comb it, thereby combing and breaking the fibrous material into multiple fiber filaments, fully dispersing the confined material so that it cannot re-clump together. Furthermore, gaps are created between the combed fibers, allowing the remaining components in the required mixture to enter and fully mix with the fibrous material, thereby improving the mixing uniformity and stability.

[0051] In the above illustrative embodiment, in the mixer with the novel stirring device, the two sides of the stirring blade 501 of the blade assembly 52 in the stirring device 5 are set as serrations 502. During the rotation, the material is stirred and cut, which not only makes the material easier to cut and mix, but also the cutting of the serrations 502 can pierce the fibrous material and comb it into multiple fiber filaments, so that the fibrous material is fully dispersed and the remaining material components fully enter the gap and mix with it, improving the mixing uniformity and stability. This solves the problem that the current mixer with the traditional stirring device is prone to losing its dispersion state and has low mixing uniformity and stability when applied to high viscoelastic materials and fibrous materials.

[0052] In some embodiments, the outer edges of the plurality of blade assemblies 52 are staggered along the axial direction, that is, the outer diameters of each blade assembly 52 are arranged in alternating sizes along the axial direction, and the outer edge of the overall structure formed by the plurality of blade assemblies 52 is wavy, with a depression formed at the blade assembly 52 with the smaller outer diameter. When the fibrous or highly viscous material is agitated by rotation, the material can more easily enter the gap between adjacent blade assemblies 52 through the blade assembly 52 with the smaller outer diameter, so that the stirring blade 501 with serrations 502 can fully contact the fibrous or highly viscous material, thereby improving the cutting and combing effect and enhancing the stirring effect.

[0053] In some embodiments, the multiple stirring blades 501 in the blade assembly 52 are arranged at equal angles, and the stirring blades 501 of adjacent blade assemblies 52 are staggered in the axial direction, thereby ensuring that there are multiple stirring blades 501 at each angular position of the stirring device 5 in the circumferential direction, and enabling the stirring blades 501 of the upper and lower layers to form multi-level cutting and stirring of the same part of the material, thereby improving the stirring effect of the stirring device 5.

[0054] In some embodiments, the inner end of the stirring blade 501 is fixedly connected to the stirring shaft 51, and serrations 502 are provided on the end face of the outer end of the stirring blade 501. The outer end of the stirring blade 501 extends outward through the serrations 502, so that the serrations 502 at the end move tangentially during rotation, better cutting the material and improving the cutting and mixing effect of the stirring device 5 on the material.

[0055] In some embodiments, the stirring blades 501 are strip-shaped and are all horizontally arranged. The stirring blades 501 are horizontal strips, which can cut the material like blades when the stirring device 5 rotates horizontally, ensuring the effect of the stirring device 5 in cutting and stirring the material.

[0056] In some embodiments, the body 1 includes a base 11, a platform 12, and a positioning adjustment pin 13.

[0057] The base 11 has support plates 14 on both sides, and the platform 12 is hinged between the two support plates 14. The mixing tank 2, the tank cover 3, and the self-rotating motor are all mounted on the platform 12. The positioning adjustment pin 13 passes through the outer positioning hole 15 provided in the support plate 14 and the inner positioning hole provided in the platform 12. Multiple outer positioning holes 15 are provided at intervals along the same arc coaxial with the hinge point.

[0058] Pulling out the positioning adjustment pin 13 allows the base 11 to swing, changing the tilt angle of the mixing tank 2. After the angle adjustment is complete, insert the positioning adjustment pin 13 into the corresponding outer positioning hole 15 and inner positioning hole to fix the base 11 at the current tilt angle, enabling mixing experiments at different angles. This makes the mixer suitable for small spaces such as laboratories and multivariate research experiments. Furthermore, as the base 11 tilts, the material in the mixing tank 2 is concentrated to one side under gravity. Then, as the mixing tank 2 rotates towards the stirring device 5, the stirring device 5 agitates the concentrated material, increasing the mixing effect.

[0059] In some embodiments, the top surface of the front part of the support plate 14 is a downwardly inclined support surface 16, the platform 12 has a platform 17, the mixing tank 2 and the tank cover 3 are both located on the upper side of the platform 17, and the self-rotating motor is located on the lower side of the platform 17.

[0060] When the platform 17 is horizontal, its rear part is attached to the top surface of the rear part of the support plate 14. When the front part of the platform 17 is attached to the support surface 16, the positioning adjustment pin 13 is inserted into an outer positioning hole 15 at the rear end.

[0061] More specifically, when the platform 17 is horizontal, the top surface of the rear part of the support plate 14 can adhere to the platform 17, providing vertical support and maintaining the stability of the platform 17. This, in turn, maintains the stability of the mixing tank 2 on the platform 17, allowing it to rotate smoothly on the horizontal plane for material mixing. When the positioning adjustment pin 13 is pulled out, the weight of the mixing tank 2 causes the front part of the platform 17 to sink and fall onto the support surface 16. The support surface 16 supports the platform 17 and limits the swing angle of the platform 17, preventing the mixing tank 2 from overturning and causing the material to spill out.

[0062] In some embodiments, the rear of the lid 3 is hinged, and the stirring device 5 is located on the rear side of the internal space of the mixing tank 2. When the lid 3 is opened, it flips backward, and the stirring device 5 swings accordingly. As the bottom of the mixing tank 2 rises, it moves forward first, positioning the stirring device 5 on the rear side of the mixing tank 2. This prevents the stirring device 5 from contacting the inner wall of the mixing tank 2 and causing collisions, thus avoiding damage to the stirring device 5 and the mixing tank 2 when the lid 3 is opened. In addition, when the mixing tank 2 tilts forward with the platform 17, the stirring device 5 is positioned on the higher side inside the mixing tank 2, allowing the material to converge on the other side of the mixing tank 2 by gravity. This prevents the stirring of the stirring device 5 from hindering the convergence of the material, and allows the converged material to be concentrated and contacted by the stirring device 5 as the mixing tank 2 rises, ensuring that the material is thoroughly mixed by its own weight and dispersed by the stirring device 5.

[0063] In some embodiments, as Figure 1 and Figure 5 As shown, the machine body 1 has a protective cover 18, the mixing tank 2 is located inside the protective cover 18, and the tank lid 3 is hinged to the protective cover 18. A locking plate 6 is installed on the tank lid 3. One end of the locking plate 6 extends into the protective cover 18 and is provided with a locking hole 61. A spring pin 7 installed on the outer wall of the protective cover 18 extends into and is inserted into the locking hole 61. A handle 62 is installed on the other end of the locking plate 6.

[0064] The spring pin 7, inserted into the locking plate 6, securely fixes the lid 3, stably sealing the protective cover 18 and the mixing tank 2. This prevents materials from spilling during mixing and, along with the protective cover 18, avoids injury to operators from contact with the mixing tank 2. Pulling the spring pin 7 and lifting the handle 62 allows the lid 3 to be flipped open, opening the mixing tank 2. This operation is convenient. Compared to using cylinders or other structures to drive the lid 3, this design is simpler, lighter, and allows for manual flipping and angle adjustment of the platform 17.

[0065] In some embodiments, a limiting support plate 63 is horizontally provided on the locking plate 6. When the spring pin 7 is inserted into the locking hole 61, the limiting support plate 63 is attached downward to the end face of the top of the protective cover 18.

[0066] By using the limiting support plate 63, the protective cover 18 can limit the locking plate 6, thereby limiting the bucket lid 3, preventing the bucket lid 3 from colliding with the protective cover 18 when it is closed, and aligning the spring pin 7 with and inserting it into the locking hole 61 to ensure that the locking of the bucket lid 3 is restored.

[0067] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0068] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
