Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a shredder rotor. Background Art

[0002] A shredder, also known as a crusher, is a device used to crush materials. During the crushing process, the rotor is driven by the drive shaft and rotates inside the positioning device. At this time, there is a certain gap between the circumferential surface of the rotor and the inner wall surface of the positioning device, and crushing teeth are provided respectively. After the material is loaded into the gap between the rotor and the stator, the material is crushed by the crushing teeth under the rotation of the rotor.

[0003] However, after a period of grinding, the rotor generates a lot of heat due to constant friction with the material, causing the operating temperature of the equipment to continue to rise. The rotor is under high temperature for a long time, which has a great impact on the strength of the rotor itself. It also has a certain impact on the state and performance of the material. Utility Model Content

[0004] The purpose of this utility model is to provide a shredder rotor. In order to solve at least the above technical problems, this utility model adopts the following technical solutions:

[0005] A shredder rotor comprises a body, a cooling groove is provided inside the body, and an inlet is provided on the end surface of the body and is communicated with the cooling groove;

[0006] Crushing teeth are arranged on the circumferential surface of the body, a crushing channel is defined between two adjacent crushing teeth, three parts are arranged along the length direction of the crushing teeth, and the crushing teeth in each part have different extension directions.

[0007] Furthermore, the main body includes a first plate, a second plate and a third plate which are stacked in sequence, and the first plate, the second plate and the third plate are all formed with crushing teeth, and the angles formed between the crushing teeth on the first plate, the second plate and the third plate and the axis are different.

[0008] Furthermore, the crushing teeth located on the first plate, the second plate and the third plate are arranged in an interlaced manner, and the ends of the crushing teeth located on the second plate partially block the crushing channels on the first plate and the third plate.

[0009] Furthermore, a first groove is formed on the end surface of the second plate facing the first plate, and the first plate is sealed and connected to the second plate.

[0010] Furthermore, a second groove is formed on the end surface of the second plate facing the third plate, and the second plate is sealed to the third plate to seal the second groove.

[0011] Furthermore, a toggle assembly is provided on the end surface of the main body, and the toggle assembly is provided on the end surface of the main body, and the toggle assembly includes a plurality of toggle arms arranged at equal angles and spaced apart from each other, and the plurality of toggle arms extend from the middle of the end surface of the main body toward the outside.

[0012] Furthermore, the toggle assembly also includes a base, which is formed in the middle of the end surface of the main body. One end of a plurality of toggle arms is formed on the base, and the other end extends to the edge of the end surface of the main body. All the toggle arms are spirally arranged and extend toward the outward direction.

[0013] Furthermore, the other end face of the body is formed with two symmetrically arranged protrusions, at least part of the surface of the protrusions and the circumferential surface of the body are located on the same circumferential surface of the cylinder, and the crushing teeth extend above the circumferential surface of the protrusions.

[0014] The beneficial effects produced by the utility model are as follows:

[0015] During the rotation of the rotor, the material is located in the gap between the rotor and the stator. The material is continuously ground by the crushing teeth on the rotor and the crushing teeth on the stator, thereby crushing the material and dropping it into the crushing channel. During the crushing process, the crushing teeth are arranged into three parts with different extension directions, such as Figure 1 As shown, in this embodiment, the grinding teeth are shaped like three broken lines. This allows the grinding angle of the material to be varied during the grinding process, resulting in a more thorough grinding of the material. More importantly, a cooling tank is provided within the body to hold cooling liquid, which cools the body and reduces the rate of temperature rise during operation. This ensures that the rotor maintains a relatively low temperature during operation, minimizing the impact on the material and the rotor itself. It is worth noting that during rotor assembly, coolant is sealed within the cooling tank, absorbing the heat generated by the grinding teeth during the grinding process, thereby reducing the temperature of the grinding teeth themselves and preventing them from affecting their temperature. This also prevents the relatively hot grinding teeth from heating the material and affecting its condition. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0023] like Figure 1-5 As shown, an embodiment of the present invention provides a shredder rotor that cooperates with a stator 200 to crush materials. During the crushing process, the rotor is connected to the drive shaft and is driven to rotate by the drive shaft, so that the material between the rotor and the stator 200 is crushed by the rotation of the rotor.

[0024] Specifically, such as Figure 1-3 As shown, the shredder rotor provided in this embodiment includes a body 100, a cooling groove 110 is opened inside the body 100, and an inlet is provided on the end surface of the body 100 and communicates with the cooling groove 110; crushing teeth 102 are also provided on the body 100, and the crushing teeth 102 are arranged on the circumferential surface of the body 100, and a crushing channel 103 is defined between two adjacent crushing teeth 102. The crushing teeth 102 are provided with three parts along the length direction, and the crushing teeth 102 of each part have different extension directions.

[0025] like Figure 4-5As shown in FIG. 1 , there is an assembly diagram and an exploded diagram of the rotor and the stator 200 provided in an embodiment of the present invention. During the crushing process, the rotor is placed in the crushing cavity 201 of the stator 200 and is mounted on the drive shaft via a sliding key. The drive shaft drives the rotor to rotate in the crushing cavity 201. During the rotation of the rotor, the material is located in the gap between the rotor and the stator 200. The crushing teeth 102 on the rotor and the crushing teeth 102 on the stator 200 continuously grind the material, thereby crushing the material and dropping it into the crushing channel 103. During the crushing process, since the crushing teeth 102 are provided with three parts having different extension directions, as shown in FIG. Figure 1 As shown, in this embodiment, the crushing teeth 102 are shaped like three broken lines. This allows the grinding angle of the material to be varied during the grinding process, resulting in a more complete grinding of the material. More importantly, a cooling tank 110 is provided within the body 100 to contain cooling liquid. This cools the body 100, reducing the rate of temperature rise during operation and ensuring a lower temperature for the rotor during operation, minimizing the impact on the material and the rotor itself. It is worth noting that during rotor assembly, the coolant is sealed within the cooling tank 110, absorbing the heat generated by the crushing teeth 102 during the grinding process. This reduces the temperature of the crushing teeth 102 themselves, preventing them from being affected. This also prevents the relatively hot crushing teeth 102 from heating the material during grinding, potentially affecting its condition.

[0026] In this embodiment, the body 100 is provided with three parts, such as Figure 2-3 As shown, the main body comprises a first plate 105, a second plate 106, and a third plate 107, which are stacked in sequence. Crushing teeth 102 are formed on each of the first, second, and third plates 105, 106, and 107. The crushing teeth 102 on each of the first, second, and third plates 105, 106, and 107 form different angles with the axis. By using three plates, each section of the crushing teeth 102 can be machined separately, reducing processing and assembly costs. Furthermore, the crushing teeth 102 on the first, second, and third plates 105, 106, and 107 are staggered, and the ends of the crushing teeth 102 on the second plate 106 partially block the crushing channels 103 on the first and third plates 105, 107. By staggering the crushing teeth 102 on each plate, the cross-sectional area of ​​the crushing channel 103 is reduced during the docking of each plate, thereby reducing the smoothness of the material passing through the crushing channel 103. After increasing the resistance, the material can be ground more times, thereby improving the grinding effect.

[0027] In the present invention, the cooling groove 110 is provided on the second plate 106. Specifically, a first groove 111 is formed on the end surface of the second plate 106 facing the first plate 105. The first plate 105 is sealed with the second plate 106. In this embodiment, the first groove 111 constitutes a cooling groove 110 for holding coolant. During the assembly process, the first plate 105 is tightly connected to the second plate 106 by bolts, so that the coolant can be sealed in the first groove 111 to absorb heat during the grinding of the material.

[0028] In other embodiments, a second groove 112 may also be provided on the end surface of the second plate 106 facing the third plate 107. Similarly, the first plate 105 and the second plate 106 are respectively provided on the two end surfaces of the second plate 106, thereby increasing the volume for accommodating the coolant and improving the ability to absorb temperature. In this embodiment, the second plate 106 is sealedly connected to the third plate 107 by bolts, so that the coolant is sealed in the second groove 112.

[0029] In this embodiment, in order to load the material into the gap between the rotor and the stator 200, a shifting assembly 120 is provided on the rotor, which can shift the material that has not been put into the gap between the rotor and the stator 200 into the gap during the rotation of the rotor. Figure 1 As shown, the toggle assembly 120 is disposed on the end surface of the body 100 and includes a plurality of toggle arms 121 spaced equiangularly from one another. The toggle arms 121 extend outward from the center of the end surface of the body 100. As the rotor rotates, centrifugal force forces material on the end surface of the body 100 along the extension direction of the toggle arms 121 into the gap between the stator 200 and the rotor, improving material delivery accuracy and preventing waste.

[0030] The toggle assembly 120 also includes a base 122, which is formed in the middle of the end face of the body 100. A plurality of toggle arms 121 are formed on one end of the base 122 and extend to the edge of the end face of the body 100. All toggle arms 121 are arranged in a spiral pattern and extend outward. Arranging the toggle arms 121 in a spiral pattern allows for better centrifugal movement of the material, improving the efficiency of the movement toward the gap between the stator 200 and the rotor.

[0031] In this embodiment, two symmetrically positioned protrusions 108 are formed on the other end face of the body. At least portions of the protrusions 108 are located on the same cylindrical circumference as the body, and the crushing teeth 102 extend above the circumferential surface of the protrusions 108. The symmetrical arrangement of the two protrusions 108 increases the rotor's rotational inertia under the action of centrifugal force during rotor rotation, ensuring continuous rotation. The rotor does not stop immediately after the drive motor stops, but instead continues to rotate for a certain period of time under the action of inertia, thereby completely discharging material within the crushing channel 103.

[0032] In this embodiment, a hole 109 for installing the drive shaft is provided on the main body 100, and an opening 101 is provided on the first plate 105, and an end cover 104 is provided at the opening 101 for sealing. The end cover 104 is fixedly connected to the drive shaft by bolts, so that the main body 100 is installed on the drive shaft. The setting of the end cover 104 prevents the main body 100 from moving along the axial direction of the drive shaft.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention is disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention. Any technician familiar with the profession can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical content disclosed above.
