Description

Technical Field

[0001] This application belongs to the field of roller press technology, and specifically relates to a roller press roller. Background Technology

[0002] A roller press, also known as an extrusion mill or roller mill, is a type of grinding equipment for materials with high crushing capacity. A roller press consists of two opposing, synchronously rotating extrusion rollers: a first extrusion roller and a second extrusion roller. When the material to be crushed passes between the first and second extrusion rollers, the rollers compress the material, reducing its volume and thus achieving crushing.

[0004] During the operation of the roller press, when the extrusion roller is subjected to the reaction force and heat generated by the material to be crushed, the extrusion roller will undergo stress deformation and thermal deformation, which will reduce the service life of the extrusion roller.

[0041] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0042] 1. This application provides a roller for a roller press, comprising: a support shaft, a stator, a rotor, a rotating component, and a roller. The support shaft is used to connect to an external roller press; the stator is fixedly mounted on the support shaft; the rotor is rotatably mounted on the support shaft, located on the side of the stator away from the support shaft and connected to the stator; the rotating component is rotatably mounted on the support shaft, forming a cavity with the support shaft, in which the stator and rotor are respectively housed, and the side of the rotor away from the stator is connected to the rotating component; the roller is located on the side of the rotating component away from the support shaft; the rotating component has a fixed portion and a supporting portion, the fixed portion abutting against the roller; in the axial direction of the support shaft, the supporting portion and the roller are spaced apart, and in the axial direction of the support shaft, the rotating component and the stator are spaced apart.

[0043] In this roller press structure, the gap between the support and the roller reduces the contact area between the rotating component and the roller, thereby reducing the heat exchange area and lowering the heat transfer rate between them, thus protecting the rotating component. In the axial direction of the support shaft, the gap between the rotating component and the stator isolates them from direct contact, further preventing heat transfer and protecting the stator.

[0044] It should be noted that when the part to be crushed comes into contact with the roller, the irregular shape of the part will cause the roller surface to be deformed by collision. The deformed shape will extend towards the end closer to the rotor. The gap between the support and the roller can accommodate the deformation of the roller, so as to reduce the collision of the deformation of the roller with the rotor, thereby protecting the rotor.

[0045] 2. This application provides a roller for a roller press, wherein one of a first guide portion and a second guide portion forms an inlet cavity, and the other of the first guide portion and the second guide portion forms an outlet cavity; the inlet cavity, the isolation cavity, and the outlet cavity are sequentially connected; at least a portion of the inlet cavity is disposed on the rotating member and is connected to the outside, and the inlet cavity is used to contain a cooling medium; at least a portion of the outlet cavity is disposed on the rotating member and is connected to the outside, and the outlet cavity is used to contain a cooling medium; in the radial direction of the support shaft, the lowest position of the connection between the outlet cavity and the isolation cavity is higher than the highest position of the support portion.

[0046] In this type of roller press, the surface temperature of the cooling medium is lower than the internal temperature of the isolation chamber. During the flow of the cooling medium in the isolation chamber, thermal convection can occur between the cooling medium and the isolation chamber to reduce the internal temperature of the isolation chamber, thereby protecting the rotating parts.

[0047] It is understandable that as the cooling medium flows from the inlet chamber into the isolation chamber, the liquid level of the cooling medium in the isolation chamber increases in the radial direction of the support shaft. The lowest position of the connection between the outlet chamber and the isolation chamber is higher than the highest position of the support, which ensures that the support can be completely immersed in the cooling medium to cool the support and thus reduce the internal temperature of the isolation chamber.

[0067] Example

[0068] An embodiment of this application provides a roller for a roller press, comprising: a support shaft 1, a stator 2, a rotor 3, a rotating component 4, and a roller 5. The support shaft 1 is used to connect to an external roller press; the stator 2 is fixedly mounted on the support shaft 1; the rotor 3 is rotatably mounted on the support shaft 1, and is located on the side of the stator 2 opposite to the support shaft 1 and is connected to the stator 2 in a mating connection; the rotating component 4 is rotatably mounted on the support shaft 1, and the rotating component 4 and the support shaft 1 enclose a cavity 6, in which the stator 2 and the rotor 3 are respectively accommodated, and the side of the rotor 3 opposite to the stator 2 is connected to the rotating component 4 in a transmission connection; the roller 5 is located on the side of the rotating component 4 opposite to the support shaft 1.

[0069] It should be noted that the rotor 3 will rotate relative to the stator 2 under the drive force, so as to drive the rotating part 4 to rotate around the support shaft 1 as the rotation center, and drive the roller 5 to rotate around the support shaft 1 as the rotation center.

[0070] It should be noted that the rotating member 4 has a fixed part 41 and a supporting part 42, with the fixed part 41 abutting against the roller 5; in the radial direction of the supporting shaft 1, the supporting part 42 is spaced apart from the roller 5, and in the axial direction of the supporting shaft 1, the rotating member 4 is spaced apart from the stator 2.

[0071] Understandably, when the roller 5 is rotating, the gap between the support part 42 and the roller 5 reduces the contact area between the rotating part 4 and the roller 5, thereby reducing the heat exchange area between the rotating part 4 and the roller 5, and thus reducing the heat transfer rate between the rotating part 4 and the roller 5, thereby protecting the rotating part 4. In the axial direction of the support shaft 1, the gap between the rotating part 4 and the stator 2 can isolate the direct contact between the rotating part 4 and the stator 2, thereby isolating the heat transfer between the rotating part 4 and the stator 2, thereby protecting the stator 2.

[0072] It should be noted that when the crushed part comes into contact with the roller 5, the irregular shape of the crushed part will cause the surface of the roller 5 to be deformed into a concave shape when it collides with the roller 5. The concave shape will extend towards the end closer to the rotor 3. The gap between the support part 42 and the roller 5 can accommodate the deformation of the roller 5, so as to reduce the collision of the deformation of the roller 5 with the rotor 3, thereby protecting the rotor 3.

[0073] Therefore, the rollers of the press provided in the embodiments of this application can solve the technical problem that stress deformation and thermal deformation of the extrusion roller will reduce the service life of the extrusion roller.

[0074] The roller 5 and the rotating member 4 provided in the embodiments of this application together form an isolation cavity 7, which is disposed on the side of the placement cavity 6 away from the support shaft 1; the placement cavity 6 and the isolation cavity 7 are spaced apart in the radial direction of the support shaft 1.

[0075] It should be noted that the isolation chamber 7 can separate the roller 5 and the placement chamber 6 to reduce the impact of the deformation of the roller 5 on the placement chamber 6, thereby protecting the rotor 3 and improving the operating stability of the rotor 3.

[0076] The rotating member 4 provided in the embodiments of this application is provided with at least one first guide part 45 and at least one second guide part 46. One end of the first guide part 45 and the second guide part 46 are respectively connected to the isolation cavity 7, and the other end of the first guide part 45 and the second guide part 46 are respectively connected to the outside.

[0077] It should be noted that the isolation cavity 7 can accommodate the cooling medium. The cooling medium has a variety of different conduction methods between the first guide part 45, the isolation cavity 7 and the second guide part 46. The conduction methods of the cooling medium between the first guide part 45, the isolation cavity 7 and the second guide part 46 will be illustrated below.

[0078] In one feasible implementation, the cooling medium can be guided into the isolation chamber 7 by the first guide part 45 under the drive of the first external force, and then discharged to the outside through the second guide part 46 to cool the isolation chamber 7.

[0079] In another feasible implementation, the cooling medium can be guided into the isolation chamber 7 by the second guide part 46 under the drive of the second external force, and then discharged to the outside through the first guide part 45 to cool the isolation chamber 7.

[0080] It should be noted that the communication method between the first guide part 45, the isolation cavity 7 and the second guide part 46 is not limited and can be selected according to actual usage requirements, as long as the cooling medium can cool the isolation cavity 7.

[0081] It should be noted that there are several different ways to set the cooling medium. The following are examples of how to set the cooling medium.

[0082] In one feasible implementation, the cooling medium can be air. The internal temperature of the isolation chamber 7 is higher than the ambient air temperature. During the air circulation process, the internal temperature of the isolation chamber 7 will carry out heat exchange with the ambient temperature, thereby reducing the internal temperature of the isolation chamber 7.

[0083] In another feasible implementation, the cooling medium can be water. The internal temperature of the isolation chamber 7 is higher than the temperature of the water. During the flow of water, the internal temperature of the isolation chamber 7 will be driven to exchange heat with the water temperature, thereby reducing the internal temperature of the isolation chamber 7.

[0084] Understandably, there are no restrictions on the specific setting of the cooling medium; it can be selected according to actual usage requirements, as long as it can reduce the internal temperature of the isolation chamber 7.

[0085] In the embodiments of this application, one of the first guide portion 45 and the second guide portion 46 forms an inlet cavity 71, and the other of the first guide portion 45 and the second guide portion 46 forms an outlet cavity 72; the inlet cavity 71, the isolation cavity 7, and the outlet cavity 72 are sequentially connected.

[0086] It should be noted that the inlet cavity 71 and the outlet cavity 72 have several different settings. The following are examples illustrating the settings of the inlet cavity 71 and the outlet cavity 72.

[0087] In one feasible implementation, the first guide portion 45 forms an inlet cavity 71, and the second guide portion 46 forms an outlet cavity 72. The inlet cavity 71, the isolation cavity 7, and the outlet cavity 72 are sequentially connected.

[0088] In another feasible implementation, the second guide portion 46 forms an inlet cavity 71, and the first guide portion 45 forms an outlet cavity 72. The inlet cavity 71, the isolation cavity 7, and the outlet cavity 72 are sequentially connected.

[0089] It is understandable that there are no restrictions on the setting of the inlet cavity 71 and the outlet cavity 72. They can be selected according to actual usage needs, as long as the inlet cavity 71, the isolation cavity 7, and the outlet cavity 72 are connected in sequence.

[0090] It should be noted that at least a portion of the inlet cavity 71 is disposed on the rotating member 4 and is connected to the outside, and the inlet cavity 71 is used to contain the cooling medium; at least a portion of the outlet cavity 72 is disposed on the rotating member 4 and is connected to the outside, and the outlet cavity 72 is used to contain the cooling medium.

[0091] Understandably, the cooling medium flows into the inlet cavity 71 under the drive of the fifth external force, and after passing through the isolation cavity 7, it is guided to the outlet cavity 72 to be guided to the outside. The surface temperature of the cooling medium is lower than the internal temperature of the isolation cavity 7. During the flow of the cooling medium in the isolation cavity 7, thermal convection can occur between the cooling medium and the isolation cavity 7 to reduce the internal temperature of the isolation cavity 7, thereby protecting the rotating part 4.

[0092] It should be noted that, in the radial direction of the support shaft 1, the lowest position of the connection between the outlet cavity 72 and the isolation cavity 7 is higher than the highest position of the support part 42.

[0093] It is understandable that as the cooling medium flows into the isolation chamber 7 through the inlet chamber 71, the liquid level of the cooling medium in the isolation chamber 7 increases in the radial direction of the support shaft 1. The lowest position of the connection between the outlet chamber 72 and the isolation chamber 7 is higher than the highest position of the support part 42, which can ensure that the support part 42 can be completely immersed in the cooling medium to cool the support part 42, thereby reducing the internal temperature of the isolation chamber 7.

[0094] The stator 2 and the support shaft 1 provided in the embodiments of this application enclose at least one cooling cavity 8. The cooling cavity 8 is formed with a third guide portion and a fourth guide portion. One end of the third guide portion and the fourth guide portion are respectively connected to the cooling cavity 8, and the other end of the third guide portion and the fourth guide portion are respectively connected to the outside.

[0095] It should be noted that the cooling medium can flow between the third guide section, the cooling chamber 8 and the fourth guide section. The cooling medium has a variety of different flow methods, which will be illustrated below with examples.

[0096] In one feasible implementation, the cooling medium can flow into the cooling chamber 8 after passing through the third guide section under the drive of the third external force, and then be discharged to the outside through the fourth guide section.

[0097] In another feasible implementation, the cooling medium can flow into the cooling chamber 8 after passing through the fourth guide section under the drive of the fourth external force, and then be discharged to the outside through the third guide section.

[0098] Understandably, there are no restrictions on the flow method of the cooling medium, and it can be selected according to actual usage requirements.

[0099] The rollers of the roller press provided in the embodiments of this application further include: a water inlet pipe 81 and a water outlet pipe 82, wherein the water inlet pipe 81 is disposed on the support shaft 1 and the water outlet pipe 82 is disposed on the support shaft 1.

[0100] It should be noted that there are multiple ways to connect the inlet pipe 81 and the outlet pipe 82. Examples of the connection positions of the inlet pipe 81 and the outlet pipe 82 will be given below.

[0101] In one feasible implementation, one side of the water inlet pipe 81 is connected to the third guide section, and the other side of the water inlet pipe 81 is connected to the outside; one side of the water outlet pipe 82 is connected to the fourth guide section, and the other side of the water outlet pipe 82 is connected to the outside.

[0102] In another feasible implementation, one side of the water inlet pipe 81 is connected to the fourth guide section, and the other side of the water inlet pipe 81 is connected to the outside; one side of the water outlet pipe 82 is connected to the third guide section, and the other side of the water outlet pipe 82 is connected to the outside.

[0103] It should be noted that there are no restrictions on the connection positions of the water inlet pipe 81 and the water outlet pipe 82. They can be selected according to actual usage requirements, as long as the water inlet pipe 81, the cooling chamber 8, and the water outlet pipe 82 are connected in sequence.

[0104] It should be noted that the cooling medium, driven by the sixth external force, flows through the inlet pipe 81 into the cooling chamber and is then guided to the outside through the outlet pipe 82. The surface temperature of the cooling medium is lower than the internal temperature of the cooling chamber. During the flow of the cooling medium in the cooling chamber, thermal convection can occur between the cooling medium and the cooling chamber to reduce the internal temperature of the cooling chamber, thereby protecting the stator 2.

[0105] It should be noted that at least a portion of the water inlet pipe 81 is disposed on the support shaft 1 and extends toward the side close to the cooling chamber and communicates with the cooling chamber. The water inlet pipe 81 is used to guide the external cooling medium into the cooling chamber.

[0106] It should be noted that at least a portion of the water outlet pipe 82 is disposed on the support shaft 1 and extends toward the side close to the cooling chamber and communicates with the cooling chamber. The water outlet pipe 82 is used to guide the external cooling medium into the cooling chamber.

[0107] It should be noted that there are several different positional relationships between the water inlet pipe 81 and the water outlet pipe 82. Examples of the positional relationships between the water inlet pipe 81 and the water outlet pipe 82 will be given below.

[0108] In one feasible implementation, the inlet pipe 81 and the outlet pipe 82 are coaxially arranged.

[0109] In another feasible implementation, the inlet pipe 81 and the outlet pipe 82 are arranged at least partially parallel.

[0110] In addition, in other feasible embodiments, the water inlet pipe 81 and the water outlet pipe 82 are coaxially arranged and parallel to each other, that is, the water inlet pipe 81 and the water outlet pipe 82 are concentrically arranged.

[0111] It is understandable that the positional relationship between the water inlet pipe 81 and the water outlet pipe 82 is not restricted and can be selected according to actual usage needs, as long as the water inlet pipe 81, the cooling chamber, and the water outlet pipe 82 are connected in sequence.

[0112] It should be noted that when the inlet pipe 81 and the outlet pipe 82 are set concentrically, the inlet pipe 81 and the outlet pipe 82 can be arranged in a variety of different ways. The arrangement of the inlet pipe 81 and the outlet pipe 82 will be illustrated with examples below.

[0113] In one possible implementation, the diameter of the inlet pipe 81 is larger than the diameter of the outlet pipe 82, and the outlet pipe 82 is accommodated in the inlet pipe 81.

[0114] In another feasible implementation, the diameter of the inlet pipe 81 is smaller than the diameter of the outlet pipe 82, and the inlet pipe 81 is accommodated in the outlet pipe 82.

[0115] It is understandable that when the inlet pipe 81 and the outlet pipe 82 are concentrically arranged, there is no restriction on the specific arrangement of the inlet pipe 81 and the outlet pipe 82. They can be selected according to the actual needs of use. The inlet pipe 81 and the outlet pipe 82 of this structure have the advantage of compact structure.

[0116] The embodiments of this application provide a plurality of cooling chambers 8, which are spaced apart and connected to each other through holes.

[0117] It should be noted that there are various ways to arrange the multiple cooling chambers 8. The following are examples of the connection methods between the multiple cooling chambers 8.

[0118] In one feasible implementation, multiple cooling chambers 8 are stacked in the radial direction of the support shaft 1, and the cooling chamber 8 located in the upper layer and the cooling chamber 8 located in the lower layer are connected by a first through hole, through which the cooling medium can pass and circulate between two adjacent cooling chambers 8.

[0119] In another feasible implementation, multiple cooling chambers 8 are stacked in the radial direction of the support shaft 1. The cooling chamber 8 closer to the water inlet pipe 81 and another adjacent cooling chamber 8 are connected by a second through hole, and the cooling medium can pass through the second through hole and flow between the two adjacent cooling chambers 8.

[0120] It is understandable that there are no restrictions on the connection method between multiple cooling chambers 8, and it can be selected according to the actual use requirements, as long as the cooling medium can pass through the through hole and flow between two adjacent cooling chambers 8.

[0121] The rotating component 4 provided in the embodiments of this application includes: a first rotating part 43, a second rotating part 44, and a connecting part.
