Description

Technical Field

[0001] This utility model relates to the field of grinding mill technology, and more specifically, to a new type of high-speed grinding mill. Background Technology

[0002] A grinding mill is a mechanical device used to grind solid materials into powder, and it is widely used in mining, metallurgy, chemical, building materials, pharmaceutical, food and other industries. Most existing toner mills use two opposing rotating rollers below the feed inlet. As the material passes through, it is crushed and ground into powder by the textured outer edges of the rollers. However, this method relies on only two rollers for grinding, and using multiple rollers would increase costs and result in lower grinding efficiency. Therefore, we propose a new high-speed grinding mill. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a new type of high-speed grinding mill to solve the technical problem of low grinding efficiency at present.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel high-speed grinding mill, comprising a vertical grinding shell, a feed inlet installed at the top of the vertical grinding shell, a drive motor installed at the center of the top of the vertical grinding shell, a central rod connected to the drive end of the drive motor, multiple throwing blades installed on the outer periphery of the central rod, multiple grinding rollers arranged in a circular array around the vertical grinding shell on the outer periphery of the throwing blades, a driving joint structure provided between the multiple grinding rollers, a grinding structure provided between the bottoms of the multiple grinding rollers, and a discharge port provided at the center of the grinding structure.

[0005] Preferably, the vertical grinding mill housing has a discharge pipe at the bottom center that communicates with the discharge port, and the feed port is located between the inner circumferences of multiple grinding rollers, with the multiple grinding rollers arranged in groups of two.

[0006] Preferably, the combined structure includes multiple central shafts connected to the center of the grinding rollers, with a high gear mounted at the top of the central shaft, the high gear meshing with a low gear on its outer periphery, and the low gear and the high gear being fixed to the central shafts of a set of two grinding rollers.

[0007] Preferably, a ring gear is provided between the plurality of high gears, the ring gear meshes with the high gears and does not contact the low gears, and a plurality of connecting rods connect the ring gear to the central rod.

[0008] Preferably, the grinding structure includes a concave cone and a convex cone in the shape of a pointed cone. The convex cone and the concave cone are provided with spiral ridges on adjacent sides. A grinding gap is formed between the two spiral ridges. The convex cone is connected to a central rod. The concave cone is fixed to the vertical grinding shell. The center of the concave cone is the discharge area.

[0009] Preferably, a protective shell is provided between the outer peripheries of the plurality of high gears and low gears, and the top of the convex cone is provided with a slope plate that is movably sleeved on the outer periphery of the central rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model utilizes multiple sets of grinding rollers, in conjunction with a central rod and a material-throwing blade, to quickly convey incoming material to the grinding position of the grinding rollers. Furthermore, through the meshing of high and low gears and the contact meshing of the ring gear with the high gear, combined with the fixing of the connecting rod and the central rod, the rotation of the central rod can drive the synchronous operation of multiple sets of grinding rollers, improving grinding efficiency while saving economic costs. The circular array distribution of multiple rollers also reduces the size of the equipment itself, solving the problem of low grinding efficiency.

[0012] 2. This utility model also improves the grinding effect by using the design of concave and convex cones and the matching of threaded convex patterns, and by connecting the central rod with the convex cone, combined with the design of the filling plate slope surface to facilitate material feeding.

[0013] It is worth mentioning that all the above actions are driven by only one central rod and drive motor. Multiple grinding and throwing actions are achieved by one motor, which is highly functional and greatly reduces economic costs. Attached Figure Description

[0021] like Figures 1 to 4 As shown, this utility model relates to a novel high-speed grinding mill, comprising a vertical grinding shell 1, a feed inlet 2 installed at the top of the vertical grinding shell 1, a drive motor 3 installed at the center of the top of the vertical grinding shell 1, and a discharge pipe (not shown) located at the center of the bottom of the vertical grinding shell 1. Inside the vertical grinding shell 1, multiple grinding rollers 6 are arranged in a circular array centered on the vertical grinding shell 1. The feed inlet 2 is located between the inner circumferences of the multiple grinding rollers 6, which are arranged in pairs. To quickly convey the material to the grinding position, a central rod 4 is connected to the drive end of the drive motor 3. Multiple throwing blades 5 are installed on the outer circumference of the central rod 4. The throwing blades 5 rotate at high speed to throw the material. To achieve integrated linkage, a drive connection structure 7 is provided between the multiple grinding rollers 6. The combined structure 7 includes multiple central shafts 701 connected to the center of the grinding rollers 6. A high gear 702 is installed at the top of the central shaft 701. The outer periphery of the high gear 702 meshes with a low gear 703. The low gear 703 and the high gear 702 are fixed to the central shaft 701 of a set of two grinding rollers 6. A ring gear 704 is provided between the multiple high gears 702. The ring gear 704 meshes with the high gears 702 and does not contact the low gear 703. Multiple connecting rods 705 are connected between the ring gear 704 and the central rod 4. In order to protect the gears, a protective shell 9 is provided between the outer periphery of the multiple high gears 702 and the low gears 703. Since there is a gap between each set of grinding rollers 6, in order to prevent material from passing through the gap, a filling plate 11 is fixed at the bottom of the protective shell 9. The filling plate 11 is in contact with the two adjacent grinding rollers 6.

[0022] Working principle: During use, the drive motor 3 is controlled by an external control structure to rotate the central rod 4, causing the material-throwing blade 5 to rotate. The material is then fed into the feed port 2 and thrown at high speed by the material-throwing blade 5 onto the grinding roller 6. The rotation of the central rod 4 drives the connecting rod 705 to rotate, causing the high gear 702 to rotate. Through the meshing of the gears, multiple grinding rollers 6 can rotate synchronously. The gear meshing design allows corresponding sets of two grinding rollers 6 to rotate in opposite directions, thus achieving simultaneous grinding of materials by multiple sets of rollers. Moreover, relying on a single motor does not increase economic costs, and the circular array distribution of multiple rollers also reduces the size of the equipment itself.

[0023] To facilitate multiple grinding operations, a grinding structure 8 is provided between the bottoms of multiple grinding rollers 6. The grinding structure 8 has a discharge port at its center, located at the discharge pipe position. The grinding structure 8 includes a concave cone 801 and a convex cone 802, both tapered in shape. The diameter of the convex cone 802 is smaller than that of the concave cone 801, allowing for a feeding gap. To assist in feeding, a slope plate 10 is provided at the top of the convex cone 802, movably fitted around the outer periphery of the central rod 4. The slope plate 10 is not connected to the convex cone 802 or the central rod 4. Spiral ridges 803 are provided on both sides adjacent to the concave cone 801. A grinding gap is formed between the two spiral ridges 803. The cone 802 is connected to the central rod 4. The central rod 4 passes through the slope plate 10. The concave cone 801 is fixed to the vertical grinding shell 1. The center of the concave cone 801 is the discharge area. The design of the two spiral ridges 803, due to the spiral pattern, allows the material to move along the trajectory of the spiral ridges 803 during the grinding process, thus guiding the discharge.

[0024] Working principle: Since the convex cone 802 is connected to the central rod 4, when the central rod 4 rotates, it can also drive the convex cone 802 to rotate. In conjunction with the spiral convex texture 803 between the grinding gaps, the material can be ground again to achieve multiple grinding.

[0025] It is worth mentioning that all the above actions are achieved through the central rod 4 in conjunction with the drive motor 3, which greatly reduces the economic cost.

[0026] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
