Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to a basket mill for high-efficiency grinding. Background Technology

[0002] Basket mills, as a common material grinding equipment, are widely used in fields such as coatings, inks, and nanomaterials. They achieve efficient grinding through the combination of basket grinding media and a dispersing disc. However, traditional basket mills have the following significant drawbacks in practical use:

[0003] Basket grinding media have poor wear resistance: Traditional basket grinding media are mostly made of stainless steel. During high-speed grinding, the continuous collision between the grinding media (such as zirconium beads) and the basket can easily lead to wear on the surface of the basket, and even deformation or perforation. Frequent basket replacements not only increase production costs, but also reduce overall processing efficiency due to downtime for maintenance.

[0004] Rapid material temperature rise: During continuous grinding in traditional sand mills, the intense friction between the grinding media and the material generates a large amount of heat. However, the heat dissipation performance of the basket structure is limited, causing the material temperature to rise rapidly. To prevent the material from agglomerating or denaturing due to high temperatures, it is often necessary to reduce the grinding intensity or intermittently stop the machine for cooling in actual operation, which severely restricts the continuous production capacity of the equipment.

[0005] The contradiction between zirconium bead loading and fineness: To ensure thorough grinding, theoretically, a sufficient amount of zirconium beads is needed to increase the collision frequency between media. However, traditional basket mills, due to insufficient wear resistance of the basket and weak temperature control, cannot withstand the wear and temperature rise caused by high zirconium bead loading, resulting in limited actual loading. Insufficient zirconium beads directly affect the grinding fineness, causing uneven particle size distribution and failure to meet fineness standards, further reducing production efficiency.

[0006] In summary, traditional basket mills suffer from insufficient material wear resistance, weak temperature control, and structural design limitations, making it difficult to balance grinding efficiency and fineness requirements. There is an urgent need for a new type of basket mill that combines high wear resistance, efficient heat dissipation, and stable fineness to solve the bottleneck problems in the existing technology. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a basket mill for high-efficiency grinding, so as to solve one or more problems existing in the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency grinding basket mill, comprising: a grinding shaft rotatably mounted on the machine body, wherein suction blades and a grinding assembly are fixed on the grinding shaft; a basket grinding body suspended on the machine body by a pull rod, wherein a feed inlet is provided at the top, wherein the suction blades are arranged corresponding to the feed inlet, and the grinding assembly is housed in the basket-shaped inner cavity of the basket grinding body; and a dispersing toothed disc fixed at the end of the grinding shaft and located below the basket grinding body, for dispersing the ground material.

[0009] In one embodiment of this utility model, the grinding component is a stirring grinding rod.

[0010] In one embodiment of the present invention, the grinding assembly is a multi-layered grinding rotor, and the grinding rotor is arranged vertically in the inner cavity of the basket grinding body.

[0011] In one embodiment of the present invention, a base is also included, and a lifting cylinder is vertically provided thereon. The machine body is fixed to the top of the lifting cylinder. The outer shell is surrounded by sheet metal parts around the lifting cylinder to form a cavity for accommodating the material bucket.

[0012] In one embodiment of the present invention, the outer shell is provided with a positioner, the positioner comprising: a clamping assembly, symmetrically arranged and clamping the material bucket; a control lever, threadedly connected to the two clamps to adjust the spacing, and having a clamping handle at the end.

[0013] In one embodiment of the present invention, a guide shaft is further included, which is arranged parallel to the lifting cylinder, with its top end fixed to the machine body and its bottom end slidingly inserted into the outer shell.

[0014] In one embodiment of this utility model, the pull rod is connected to the machine body through a bearing seat, and a temperature probe is provided on the bearing seat. The bottom end of the temperature probe extends into the inner cavity of the basket grinding body, and the top end is connected to a temperature gauge.

[0015] In one embodiment of the present invention, the machine body is provided with a drive assembly, the drive assembly including: a motor with a V-belt pulley on the output shaft; and a transmission mechanism that connects the motor and the V-belt pulley on the grinding shaft via a V-belt to drive the grinding shaft to rotate.

[0016] As described above, the high-efficiency grinding basket mill of this invention has the following beneficial effects: Through optimized structural design and functional synergy, it significantly improves grinding efficiency and temperature control performance. Its high-speed rotating grinding shaft drives the suction blades and ceramic rod pin assembly, causing the material to quickly enter the inner cavity of the basket grinding body and collide with high-filling 95% pure zirconium beads at high frequency. Through the complex shearing and extrusion action between the zirconium beads, the material fineness can be rapidly reduced to the production requirements, effectively shortening the grinding cycle. The basket grinding body adopts a suspended structure combined with wear-resistant materials, reducing the wear problem caused by the impact of the media in traditional stainless steel baskets and extending the service life of the equipment. Furthermore, the cooling design integrated into the basket's sandwich layer can promptly dissipate the heat generated during the grinding process, balancing the contradiction between high-intensity collisions and temperature control. This ensures the stability of the zirconium bead filling amount for efficient fineness processing while avoiding the risk of material agglomeration or deterioration due to excessive temperature rise. The setting of the dispersing toothed disc further enhances the homogenization effect of the ground material, enabling the whole machine to have the advantages of achieving fineness standards, precise temperature control and stable quality in continuous production, making it particularly suitable for heat-sensitive materials or high-precision grinding scenarios.

[0024] This utility model provides a basket mill for high-efficiency grinding. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up, down, left, right," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example 1

[0026] Please see Figure 1 and Figure 2 This utility model provides a high-efficiency grinding basket mill, comprising: a grinding shaft 1, rotatably mounted on a machine body 2, wherein suction blades 3 and grinding components 4 are fixed on the grinding shaft 1; a basket grinding body 5, suspended on the machine body 2 by a pull rod 6, with a feed inlet at the top, wherein the suction blades 3 are arranged corresponding to the feed inlet, and the grinding components 4 are housed in the basket-shaped inner cavity of the basket grinding body 5; and a dispersing toothed disc 7, fixed to the end of the grinding shaft 1 and located below the basket grinding body 5, for dispersing the ground material.

[0027] The grinding shaft 1 drives the suction blades 3 and grinding assembly 4 to rotate at high speed, drawing material from the feed inlet into the inner cavity of the basket grinding body 5. There, the material undergoes intense collision and shearing with the zirconium beads filled in the basket cavity, achieving efficient grinding. The dispersing disc 7 further disperses the outflowing material to ensure uniform particle size. More specifically, the basket grinding body 5 has a feed inlet at the top and a discharge outlet at the bottom. The grinding shaft 1 passes through both the feed inlet and discharge outlet from top to bottom. After grinding in the basket cavity, the material flows out through the gaps in the basket structure into the inner cavity of the basket grinding body 5, then flows out from the discharge outlet, and finally is dispersed by the dispersing disc 7. Its structural design reduces vibration transmission and improves equipment stability through the suspended basket; the corresponding arrangement of the suction blades 3 and the feed inlet optimizes material suction efficiency and avoids clogging; and the independent arrangement of the dispersing disc 7 enhances the homogenization effect of the ground material, making it suitable for continuous production of materials with high fineness and high uniformity.

[0028] The grinding component 4 is a stirring grinding rod, which is a ceramic rod. When the grinding component 4 uses a stirring grinding rod, the stirring grinding rod applies a strong shear force to the material while rotating, and simultaneously pushes the zirconium beads to form a vortex, increasing the collision frequency between the material and the grinding media. The stirring grinding rod has a simple structure, low manufacturing cost, and is easy to clean and maintain. It is suitable for efficient grinding of materials with medium and low viscosity, and can reduce equipment complexity and improve economy while ensuring fineness.

[0029] The system also includes a base 8 with a vertically mounted lifting cylinder 9, to which the machine body 2 is fixed. An outer shell 10, composed of sheet metal parts, surrounds the lifting cylinder 9, forming a chamber to accommodate the material container. The base 8, equipped with the lifting cylinder 9, allows for vertical lifting and adjustment of the machine body 2, facilitating adaptation to material containers of different heights and reducing operational fatigue. The outer shell 10, composed of sheet metal parts, surrounds the lifting mechanism, forming a sealed chamber that reduces dust leakage and environmental interference, while protecting internal components from external impacts. This design enhances the equipment's versatility and safety, making it suitable for scenarios requiring rapid switching between various material container sizes.

[0030] It also includes a guide shaft 15, which is arranged parallel to the lifting cylinder 9, with its top end fixed to the machine body 2 and its bottom end sliding through the outer casing 10. The guide shaft 15, arranged parallel to the lifting cylinder 9, provides linear guidance for the lifting of the machine body 2, preventing tilting or deviation. The bottom end, sliding through the outer casing 10, reduces frictional resistance, ensuring smooth lifting. This structure enhances the stability of equipment operation, reduces the impact of vibration on grinding accuracy, and extends the service life of the lifting cylinder 9 and bearings.

[0031] The pull rod 6 is connected to the machine body 2 via a bearing seat 16. A temperature sensing guide rod 17 is mounted on the bearing seat 16. The bottom end of the temperature sensing guide rod 17 extends into the inner cavity of the basket-type grinding body 5, and the top end is connected to a thermometer 18. The temperature sensing guide rod 17 penetrates deep into the inner cavity of the basket-type grinding body 5 through the bearing seat 16, monitoring the temperature of the grinding area in real time and providing feedback through the thermometer 18. This design allows for timely adjustment of the cooling system (such as jacket cooling) to prevent material agglomeration or denaturation due to localized overheating. It also optimizes the balance between zirconium bead filling amount and temperature control, ensuring product quality stability, and is particularly suitable for processing heat-sensitive materials.

[0032] The machine body 2 is equipped with a drive assembly, which includes: a motor 19 with a V-belt pulley 20 on its output shaft; and a transmission mechanism that connects the motor 19 and the V-belt pulley 20 on the grinding shaft 1 via a V-belt 21, driving the grinding shaft 1 to rotate. The drive assembly uses the motor 19 and V-belt pulley 20 for transmission, connected to the grinding shaft 1 via the V-belt 21, achieving flexible power transmission. The V-belt drive has a buffering and vibration-absorbing effect, reducing the impact of motor 19 vibration on grinding accuracy; the belt is easy to replace, and the transmission ratio can be flexibly adjusted to adapt to different speed requirements. This design reduces equipment maintenance costs while meeting the speed control requirements of diverse production processes.

[0033] The outer casing 10 is equipped with a positioner 11 for clamping the material bucket. The positioner 11 includes: a clamping assembly 12, symmetrically arranged to clamp the material bucket; and a control lever 13, threadedly connected to the two clamps to adjust the spacing, with a clamping handle 14 at its end. The positioner 11 secures the material bucket via the symmetrical clamping assembly 12, the control lever 13 adjusts the spacing to accommodate buckets of different diameters, and the handle design facilitates quick manual locking. This structure achieves stable clamping of the material bucket without additional tools, preventing leakage or misalignment caused by shaking during grinding, while also shortening the time for changing material buckets, improving production efficiency and operational convenience.

[0034] Example 2

[0035] Please see Figure 3 and Figure 4 The difference between this embodiment and the previous embodiments is that the grinding component 4 is a multi-layered grinding rotor, which is arranged vertically within the cavity of the basket grinding body 5. The multi-layered grinding rotors, arranged vertically, form a multi-stage grinding zone. The material undergoes progressive refinement as it passes through each rotor layer, significantly improving grinding efficiency and fineness. The vertically arranged rotor design reduces the radial dimension of the equipment, saving space. Furthermore, the layered control allows for adaptation to the processing needs of materials with different particle sizes, making it particularly suitable for the fine grinding of nanomaterials and materials with high solid content.

[0036] In summary, this utility model's high-efficiency basket mill, through the synergistic action of the grinding shaft 1 integrating the suction blades 3 and the grinding components 4, allows material to be injected at high speed into the basket grinding media 5. Driven by ceramic rod pins, a high-filling-rate 95% pure zirconium bead cluster generates multi-dimensional and intense collisions, achieving ultra-fine particle crushing in a very short time, significantly breaking through the fineness bottleneck. Simultaneously, the innovatively designed jacketed cooling structure of the basket grinding media 5 precisely guides and controls heat transfer under the high-energy collision conditions of the zirconium beads, continuously neutralizing the transient temperature rise within the grinding chamber and fundamentally preventing the denaturation and agglomeration of heat-sensitive materials. The dispersing toothed disc 7 further fluidizes and disperses the grinding products, synergizing with the jacketed cooling system to form a temperature-fineness bistable output mechanism. Ultimately, while ensuring zero heat loss in product quality, it achieves high-precision, low-energy-consumption, continuous, and efficient grinding production. Therefore, this utility model effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

[0037] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
