Abstract
Description
Technical Field
[0001] The utility model relates to a grinding device, in particular to a grinding rotor and a grinding machine. Background Art
[0002] In a grinder, the grinding chamber contains a mixture of grinding media and the slurry to be ground. During grinding, the high-speed rotation of the grinding rotor drives the grinding media and the material to rotate, shear, and collide at high speed in the chamber, thereby grinding the material. However, during the grinding process, the grinding media and the material are chaotically distributed in the grinding chamber, and a large amount of material and grinding media will accumulate on the side of the mechanical seal and the separator end, affecting the service life of the mechanical seal and the separator, and resulting in poor grinding effect on the side of the mechanical seal and the separator end. Therefore, there is an urgent need for a grinding rotor that can enhance the grinding effect at the end position in the grinding chamber. Utility Model Content
[0003] The purpose of the utility model is to provide a grinding rotor and a grinding machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0004] The solution of the utility model to solve its technical problems is:
[0005] A grinding rotor comprises: a connecting seat, a connecting hole is provided in the middle of one end of which, a discharge rib is provided on the end surface of the connecting seat, and a plurality of the discharge ribs are provided around the connecting hole; a grinding block, which is connected to the outer side of the connecting seat, and a plurality of the grinding blocks are provided on the outer side of the connecting seat.
[0006] This technical solution has at least the following beneficial effects: during assembly, the external rotary drive source is connected to the connecting hole, and one end of the connecting seat provided with the discharge rib is aligned with the mechanical seal position of the grinding chamber. During operation, the connecting seat rotates in the grinding chamber, and the grinding block stirs the material between the outside of the connecting seat and the inside of the grinding chamber, thereby further accelerating the material grinding efficiency in the grinding chamber. When the connecting seat rotates, the discharge rib at its end can stir the material and grinding medium at the end position of the grinding chamber, which can effectively reduce the accumulation of material and grinding medium at the mechanical seal position of the grinding chamber, thereby increasing the effective grinding area, better improving the fluidity of the material in the grinding chamber, improving the material grinding efficiency, and reducing the wear of the grinding chamber and the grinding rotor due to the large amount of grinding medium accumulation, thereby improving the overall service life.
[0007] As a further improvement to the above technical solution, the discharge rib extends from the middle of the connecting seat in a direction away from the connecting seat. This increases the contact area between the discharge rib, the material, and the grinding media. When the discharge rib rotates, the material and the grinding media can be better thrusted in the radial direction, reducing the accumulation of material and grinding media.
[0008] As a further improvement to the above technical solution, the side of the grinding block facing away from its rotational direction forms a first angle with the outer side of the connecting base, and the side of the grinding block facing its rotational direction forms a second angle with the outer side of the connecting base, wherein the first angle is greater than the second angle. The smaller angle formed by the side of the grinding block facing its rotational direction and the outer side of the connecting base can generate a greater thrust on the material and grinding media, thereby better providing rotational driving force for the material and grinding media, and flinging the material and grinding media outward.
[0009] As a further improvement to the above technical solution, a connecting post is provided at the other end of the connecting base. Multiple connecting posts are spaced around the center of the connecting base, and the outer sides of each of the connecting posts are connected to the grinding blocks. Multiple connecting posts are connected to grinding blocks at the end of the connecting base away from the discharge rib, further increasing the grinding area. A gap is formed between adjacent connecting posts. When the material and grinding media rotate within the space formed by the multiple connecting posts, the material and grinding media are ejected outward from the gap, further improving the uniformity of the flow of the material and grinding media.
[0010] As a further improvement to the above technical solution, the present invention further includes a connecting ring, to which the ends of the plurality of connecting posts remote from the connecting base are respectively connected. The connecting ring can also connect and secure the ends of the plurality of connecting posts remote from the connecting base, so that the connecting ring and the plurality of connecting posts form a complete frame, thereby improving the stability of the overall structure.
[0011] As a further improvement to the above technical solution, a discharge trough is provided on the side of the connecting ring away from the connecting post, with both ends of the trough extending to the inner and outer sides of the connecting ring. When the connecting base rotates, centrifugal force can also be used to discharge the material trough outward at the end of the connecting ring. This further reduces the accumulation of material and grinding media at the other end of the grinding chamber, increases the grinding area for the material, and further improves grinding efficiency.
[0012] As a further improvement to the above technical solution, the discharge chute extends from the inside outward toward the direction of rotation of the connecting base. This extension of the discharge chute offset from the diameter of the connecting base increases the contact area between the material and the grinding media, thereby better generating thrust on the material and grinding media, and ejecting them outward.
[0013] As a further improvement to the above technical solution, an annular protrusion is formed on the end surface of the connecting seat, and the ends of the plurality of discharge ribs are respectively connected to the outer sides of the annular protrusion. The annular protrusion can interconnect the plurality of discharge ribs, thereby improving the structural stability of the discharge ribs and the annular protrusion on the connecting seat.
[0014] As a further improvement to the above technical solution, an annular step is formed between the inner side of the annular protrusion and the end surface of the connecting base. When the rotary drive of the peripheral device is connected to the connecting base, it can be matched with the position of the annular step, thereby enhancing the structural stability and sealing of the connection with the connecting base.
[0015] A grinding machine includes a rotating device, a grinding cylinder, and the above-mentioned grinding rotor. The rotating device is connected to the outside of the grinding cylinder. The rotating device has a rotating shaft extending into the grinding cylinder, and the rotating shaft is connected to the connecting hole.
[0016] This technical solution has at least the following beneficial effects: the rotating device provides a rotational driving force to drive the grinding rotor to rotate in the grinding cylinder. Since the grinding rotor has discharge ribs that throw the material and grinding media outward, the effective grinding area is increased, the fluidity of the material in the grinding chamber is better improved, the material grinding efficiency is improved, and the wear of the grinding chamber and the grinding rotor due to the large accumulation of grinding media is reduced, thereby increasing the overall service life.

[0024] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connecting accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.
[0025] Reference Figure 1 and Figure 2 A grinding rotor comprises: a connecting seat 1, a connecting hole 11 is provided in the middle of one end of which, a discharge rib 12 is provided on the end surface of the connecting seat 1, and a plurality of the discharge ribs 12 are provided around the connecting hole 11; a grinding block 2, which is connected to the outer side of the connecting seat 1, and a plurality of the grinding blocks 2 are provided on the outer side of the connecting seat 1.
[0026] In this grinding rotor, during assembly, the external rotary drive source is connected to the connecting hole 11, and one end of the connecting seat 1 provided with the discharge rib 12 is aligned with the mechanical seal position of the grinding chamber. During operation, the connecting seat 1 rotates in the grinding chamber, and the grinding block 2 stirs the material between the outside of the connecting seat 1 and the inside of the grinding chamber, thereby further accelerating the material grinding efficiency in the grinding chamber. When the connecting seat 1 rotates, the discharge rib 12 at its end can stir the material and grinding medium at the end position of the grinding chamber, which can effectively reduce the accumulation of material and grinding medium at the mechanical seal position of the grinding chamber, thereby increasing the effective grinding area, better improving the fluidity of the material in the grinding chamber, improving the material grinding efficiency, and reducing the wear of the grinding chamber and the grinding rotor due to the large amount of grinding medium accumulation, thereby improving the overall service life.
[0027] To improve the efficiency of ejecting the material and grinding media, in this embodiment, the discharge rib 12 extends from the middle of the connecting base 1 in the direction of rotation away from the connecting base 1. This increases the contact area between the discharge rib 12 and the material and grinding media. When the discharge rib 12 rotates, it can better exert radial thrust on the material and grinding media, reducing the accumulation of material and grinding media.
[0028] Furthermore, the side of the grinding block 2 facing away from its rotational direction forms a first angle with the outer side of the connecting base 1, and the side of the grinding block 2 facing its rotational direction forms a second angle with the outer side of the connecting base 1, wherein the first angle is greater than the second angle. The smaller angle formed by the side of the grinding block 2 facing its rotational direction and the outer side of the connecting base 1 can generate a greater thrust on the material and grinding media, thereby better providing a rotational driving force for the material and grinding media, and throwing the material and grinding media outward.
[0029] The grinding rotor can be used as an auxiliary grinding structure and is only installed near the end of the grinding chamber. For the position in the middle of the grinding chamber, other grinding structures can be used for grinding, or the grinding rotor can be directly used as the main grinding structure in the grinding chamber. Specifically, a connecting column 13 is provided at the other end of the connecting seat 1. A plurality of connecting columns 13 are arranged at intervals around the middle of the connecting seat 1, and the outer sides of the plurality of connecting columns 13 are respectively connected to the grinding blocks 2. The plurality of connecting columns 13 are respectively connected to the grinding blocks 2 at the end of the connecting seat 1 away from the discharge rib 12, which can further increase the grinding area, and a gap is formed between two adjacent connecting columns 13. When the material and the grinding medium rotate in the space formed by the plurality of connecting columns 13, the material and the grinding medium can be thrown out from the gap, further improving the uniformity of the flow of the material and the grinding medium.
[0030] The present invention further includes a connecting ring 3, and the ends of the multiple connecting posts 13 away from the connecting base 1 are respectively connected to the connecting ring 3. The connecting ring 3 can also connect and fix the ends of the multiple connecting posts 13 away from the connecting base 1, so that the connecting ring 3 and the multiple connecting posts 13 form an entire frame, thereby improving the stability of the overall structure.
[0031] Further, such as Figure 3 and Figure 4 As shown, a discharge trough 31 is provided on the side of the connecting ring 3 away from the connecting column 13. The two ends of the discharge trough 31 extend to the inner and outer sides of the connecting ring 3. When the connecting base 1 rotates, the material trough can also be discharged outward at the end position of the connecting ring 3 due to centrifugal force. This can further reduce the accumulation of material and grinding media at the other end position of the grinding chamber, increase the grinding area for the material, and further improve the grinding efficiency.
[0032] The discharge chute 31 can extend directly along the radial direction of the connecting base 1. However, in this embodiment, the discharge chute 31 extends from the inside outward toward the rotation direction of the connecting base 1. The discharge chute 31 extends away from the diameter of the connecting base 1 to increase the contact area between the material and the grinding medium, thereby better generating thrust on the material and the grinding medium, and ejecting the material and the grinding medium outward.
[0033] In some embodiments, an annular protrusion 14 is formed on the end surface of the connecting base 1, and the ends of the plurality of discharge ribs 12 are respectively connected to the outer sides of the annular protrusion 14. The annular protrusion 14 can connect the plurality of discharge ribs 12 to each other, thereby improving the structural stability of the discharge ribs 12 and the annular protrusion 14 on the connecting base 1.
[0034] To facilitate installation of the connection base 1, in this embodiment, an annular step 15 is formed between the inner side of the annular protrusion 14 and the end surface of the connection base 1. When connecting the external rotary drive to the connection base 1, the position of the annular step 15 can be matched, thereby enhancing the structural stability and sealing of the connection with the connection base 1.
[0035] like Figure 5 As shown, a grinding machine includes a rotating device 41, a grinding cylinder 42, and the above-mentioned grinding rotor. The rotating device 41 is connected to the outside of the grinding cylinder 42. The rotating device 41 has a rotating shaft extending into the grinding cylinder 42. The rotating shaft is connected to the connecting hole 11. The rotating device 41 can be a driving motor, which drives the connecting rotating shaft.
[0036] In this grinder, the rotating device 41 provides a rotational driving force to drive the grinding rotor to rotate in the grinding cylinder 42. Since the grinding rotor has discharge ribs 12 that throw the material and grinding media outward, the effective grinding area is increased, the fluidity of the material in the grinding chamber is better improved, the material grinding efficiency is improved, and the wear of the grinding chamber and the grinding rotor due to the large accumulation of grinding media is reduced, thereby increasing the overall service life.
[0037] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
