Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a shredder stator. 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 time of crushing, the stator generates a lot of heat due to constant friction with the material, causing the operating temperature of the equipment to continue to rise. The long-term high temperature of the stator has a great impact on the strength of the stator 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 stator. In order to solve at least the above technical problems, this utility model adopts the following technical solutions:

[0005] A shredder stator comprises a body, wherein a crushing cavity is defined within the body, the crushing cavity being of cylindrical structure, a plurality of evenly spaced crushing teeth being provided on the circumferential surface of the crushing cavity, and a crushing channel being defined between adjacent crushing teeth, the crushing teeth being provided in three sections along the axis of the crushing cavity, and the crushing teeth in each section extending in a different direction; a cooling groove for accommodating a cooling medium is also defined within the body, and the cooling groove surrounds the crushing cavity.

[0006] 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.

[0007] 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.

[0008] Furthermore, a first annular groove surrounding the crushing cavity is provided on the end surface of the first plate facing the second plate. The first plate and the second plate are tightly connected via a connecting piece. The first annular groove defines the cooling groove for accommodating the cooling medium.

[0009] Furthermore, a second annular groove surrounding the crushing cavity is provided on the end surface of the second plate facing the third plate. The second plate and the third plate are tightly connected via a connector. The second annular groove defines the cooling groove for accommodating a cooling medium.

[0010] Furthermore, a first inlet and a first outlet communicating with the first annular groove are provided on the first plate, and a second inlet and a second outlet communicating with the first annular groove and the second annular groove are provided on the second plate.

[0011] The beneficial effects produced by the utility model are as follows:

[0012] During the crushing process, a rotor is positioned within the crushing chamber and driven to rotate by a drive shaft. As the rotor rotates, it continuously rolls the material within the crushing space, causing it to be ground under the resistance of the stator's crushing teeth and flow into the crushing channel. The material then flows out along the crushing channel toward the outside of the crushing space. During this process, by configuring the crushing section into three sections with different extension directions—that is, the crushing teeth are configured as three segments along their length in a broken line shape—the grinding angle of the material can be varied during the continuous grinding process, thereby achieving sufficient grinding and ensuring a consistent particle size. More importantly, a cooling tank is provided within the main body to hold a cooling liquid, which cools the main body and reduces the rate of temperature rise during operation. This maintains a relatively low temperature in the stator during operation, minimizing the impact on the material and the stator itself. It is worth mentioning that during the assembly of the stator, the coolant is sealed and loaded into the cooling tank, so that the heat generated by the crushing teeth in the process of grinding the material can be absorbed, so that the temperature of the crushing teeth themselves is reduced to avoid affecting the temperature of the crushing teeth. At the same time, it also avoids the state of the material being affected by the relatively high temperature of the crushing teeth when grinding the material. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] 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.

[0021] like Figure 1-4 A shredder stator provided in an embodiment of the present invention cooperates with a shredder rotor during operation. Specifically, the rotor is disposed within a crushing chamber 101 of the stator, and a certain spacing is provided between the rotor and the crushing chamber 101 to form a crushing space in which materials are located and ground. During the rotation of the rotor, the rotor cooperates with the stator to grind the materials located within the crushing space.

[0022] Specifically, such as Figure 1-4 As shown, a shredder stator provided by an embodiment of the present invention includes a body 100. A crushing chamber 101 is defined inside the body 100. The crushing chamber 101 has a cylindrical structure. A plurality of crushing teeth 102 are evenly arranged on the circumferential surface of the crushing chamber 101, and a crushing channel 103 is defined between adjacent crushing teeth 102. The crushing teeth 102 are provided in three parts along the axial direction of the crushing chamber 101, and the crushing teeth 102 in each part have different extension directions. A cooling groove 110 for accommodating a cooling medium is also defined inside the body 100. The cooling groove 110 surrounds the crushing chamber 101.

[0023] During the grinding process of materials, Figure 4-5 As shown, Figure 4 The stator and rotor provided by the utility model cooperate with each other. Figure 5This is a schematic diagram of the stator and rotor structure provided by the present invention. During the crushing process, the rotor is positioned within the crushing chamber 101 and driven to rotate by a drive shaft. As the rotor rotates, it continuously rolls the material within the crushing space, causing it to be ground under the resistance of the stator's crushing teeth 102 and flow into the crushing channel 103. The material then flows out along the crushing channel 103 toward the outside of the crushing space. During this process, the crushing teeth 102 are arranged into three sections with different extension directions. That is, the crushing teeth 102 are arranged in a three-segment zigzag shape along their length. This allows the grinding angle to be varied during the continuous grinding of the material, ensuring sufficient grinding and ensuring a consistent particle size. More importantly, a cooling tank 110 is provided within the body 100 to hold cooling liquid. This cools the body 100, reducing the rate of temperature rise during operation and ensuring a low temperature for the stator, minimizing the impact on the material and the stator itself. It is worth noting that during the assembly of the stator, the coolant is sealed and loaded into the cooling tank 110, so that the heat generated by the crushing teeth 102 in the process of grinding the material can be absorbed, so that the temperature of the crushing teeth 102 itself is reduced to avoid affecting the temperature of the crushing teeth 102, and at the same time avoid affecting the state of the material due to the relatively high temperature of the crushing teeth 102 heating the material when grinding the material.

[0024] In this embodiment, if Figure 3-4As shown, the main body includes a first plate 120, a second plate 130 and a third plate 140 which are stacked in sequence. Crushing teeth 102 are formed on the first plate 120, the second plate 130 and the third plate 140, and the angles formed between the crushing teeth 102 on the first plate 120, the second plate 130 and the third plate 140 and the axis are different. In the process of processing the main body 100, three plates are respectively provided, and a center hole is provided inside each plate, and a crushing tooth 102 is provided on the inner wall of each center hole along the axial direction, and the extension direction of the crushing teeth 102 on each plate is set at a different angle to the axial direction, so that after the three plates are installed to each other, the crushing teeth 102 as a whole constitute three bent parts, so that the grinding angle of the material can be changed when grinding the material to ensure the particle size of the grinding. At the same time, the crushing teeth 102 on the first plate 120, the second plate 130, and the third plate 140 are arranged in a staggered manner, with the ends of the crushing teeth 102 on the second plate 130 partially blocking the crushing channels 103 on the first plate 120 and the third plate 140. By staggering the crushing teeth 102 on each plate, the cross-sectional area of ​​the crushing channels 103 is reduced when each plate is joined together, thereby reducing the smoothness of the material passing through the crushing channels 103. By increasing the resistance, the material can be ground more times, improving the grinding effect.

[0025] In this embodiment, a first annular groove 111, which surrounds the crushing chamber 101, is provided on the end surface of the first plate 120 facing the second plate 130. The first and second plates 120 and 130 are hermetically connected via a connector. The first annular groove 111 defines a cooling trough 110 for receiving a cooling medium. Simultaneously, a second annular groove 112, which surrounds the crushing chamber 101, is provided on the end surface of the second plate 130 facing the third plate 140. The second and third plates 130 and 140 are hermetically connected via a connector. The second annular groove 112 defines a cooling trough 110 for receiving a cooling medium.

[0026] That is to say, the cooling groove 110 can be composed of a first annular groove 111 arranged on the first plate 120, and can also be composed of a first annular groove 111 and a second annular groove 112. By loading coolant in the first annular groove 111 and the second annular groove 112, the stator absorbs the heat generated by the grinding material during the processing process, reduces the temperature of the stator and the material, and thus ensures the performance of the stator and the material.

[0027] In order to facilitate the injection of coolant into the cooling groove 110 and the circulation of the coolant, a first outlet 122 and a first inlet 121 are provided on the first plate 120, which can be connected to an external coolant circulation device through a pipeline. At the same time, a second inlet 131 and a second outlet 132 are provided on the second plate 130, so that the coolant in the first buffer and second annular grooves 112 can be circulated and injected.

[0028] 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. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention, which do not depart from the content of the technical solution of the present invention, are within the scope of the technical solution of the present invention.
