Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cement processing technology, and specifically relates to a heat insulation structure for equipment. Background Technology
[0002] During the operation of a cement mill, the sliding track bearing is used to support the weight of the cement mill and can also automatically adjust its position during operation to ensure stable operation of the mill. The sliding track bearing includes a sliding track and a sliding ring cover. The sliding track consists of multiple bearing pads. Two bearing pads support the mill cylinder at a certain angle to the vertical direction. During use, the cement mill cylinder rotates under the drive of the transmission component, slides and contacts the bearing pads, and generates friction, transferring the heat of the material inside the cement mill cylinder to the bearing pads, thereby causing the temperature of the sliding track bearing to rise.
[0003] Existing technology uses cooling components to cool the sliding shoes. However, during the operation of a cement mill, the mill cylinder and the bearing pads are in direct contact. The heat from the material inside the mill cylinder is continuously transferred to the sliding shoes, causing the sliding shoes to overheat and failing to block heat transfer. This is especially true in summer when the ambient temperature and the temperature of the material inside the mill are both high. The water temperature in the water tank also rises with the ambient temperature, reducing the cooling efficiency of the bearing pads. Consequently, the cement mill often experiences alarms and shutdowns due to high bearing pad temperatures. Utility Model Content

[0005] This utility model provides a heat insulation structure for equipment, including a heat-insulating component installed between the cement mill cylinder and the sliding bearing. The heat-insulating component includes a support frame fixedly connected to the outer wall of the cement mill cylinder and an annular frame slidably connected to the bearing plate. The support frame and the annular frame are fixedly connected. By preventing the cement mill cylinder and the bearing plate from direct contact, the heat-insulating component effectively blocks the transfer of heat from the material inside the cement mill cylinder, thereby reducing the operating temperature of the sliding bearing.
[0006] Preferably, the support frame consists of multiple connectors evenly distributed circumferentially along the axis of the cement mill cylinder between the cement mill cylinder and the annular frame, and the cross-section of the connector is rectangular or trapezoidal.
[0007] Preferably, the support frame is a plurality of annular bodies arranged linearly along the axis of the cement mill cylinder.
[0008] Preferably, the annular body has a through hole.
[0009] Preferably, a heat insulation plate is installed on the inner wall of the cement mill cylinder, and a wear-resistant plate is also installed on the surface of the heat insulation plate.
[0010] Preferably, there are two heat insulation plates, which are respectively installed at the feed end and the discharge end of the cement mill cylinder.
[0011] The beneficial effects of this utility model are: by setting a heat-insulating component between the cement mill cylinder and the sliding bearing, the cement mill cylinder and the bearing pad are separated from direct contact, which can effectively reduce the heat transfer of the material inside the cement mill cylinder to the sliding bearing, thereby reducing the operating temperature of the sliding bearing, preventing the cement mill from stopping due to excessive temperature, effectively solving production problems, and ensuring smooth production.

Detailed Implementation
[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0024] During the operation of a cement mill, the sliding track bearing supports the weight of the mill and automatically adjusts its position to ensure stable operation. The sliding track bearing includes a sliding track and a sliding ring cover 17. The sliding track consists of multiple bearing pads 16. Two bearing pads 16 support the mill cylinder at a certain angle to the vertical direction. In use, the cement mill cylinder 18 rotates under the drive of the transmission assembly (not shown in the figure), making sliding contact with the bearing pads 16 and generating friction. This transfers heat from the material inside the cement mill cylinder 18 to the bearing pads 16, causing the temperature of the sliding track bearing to rise. Figure 1-3 As shown, this is the existing heat insulation structure of the equipment according to this utility model. To prevent the sliding track from overheating during operation, a cooling component is installed at the sliding track bearing to cool the track. Specifically, the cooling component mainly includes a water tank 10, with an outlet pipe 11 and a return pipe 12 connected to the outlet and inlet of the water tank 10, respectively. A cooling chamber 13 is then opened inside the jack 16. The end of the outlet pipe 11 away from the water tank 10 is connected to the inlet of the cooling chamber 13, and the end of the return pipe 12 away from the water tank 10 is connected to the outlet of the cooling chamber 13. The outlet pipe 11 is also connected to a circulating pump 14, and the return pipe 12 is connected to a refrigeration component 15. The cooling component 15 can adopt the principle of fan cooling or air conditioning cooling, which is quite common in daily life and will not be described in detail here. As long as it can cool the cooling water, it is fine. In use, the circulating pump 14 drives the water in the water tank 10 into the cooling chamber 13 through the outlet pipe 11 to cool the bearing 16. Then, it flows back to the water tank 10 through the return pipe 12. Before entering the water tank 10, it is cooled by the cooling component 15, which can improve the cooling efficiency of the bearing 16, improve the working performance of the bearing, and thus optimize the overall performance of the entire equipment. The above is an introduction to the heat insulation structure of the existing equipment (cement mill).
[0025] As mentioned above, the existing technology uses cooling components to cool the sliding shoe. However, during the operation of the cement mill, the cement mill cylinder 18 and the bearing 16 are in direct contact. The heat from the material inside the cement mill cylinder 18 will continue to be transferred to the sliding shoe through the cement mill cylinder 18, causing the temperature of the sliding shoe to rise. This fails to block the heat transfer. Especially in summer when the ambient temperature is high and the temperature of the material inside the mill is also high, the temperature of the water in the water tank 10 will also rise with the ambient temperature, resulting in a decrease in the cooling efficiency of the bearing 16. This often leads to the cement mill tripping due to the high temperature of the bearing 16.
[0026] Based on the above problems, this utility model adopts the following improvement method to solve them, such as... Figure 4-10 As shown, a heat insulation structure for equipment differs from existing technologies. This invention installs a heat-insulating component 1 between the cement mill cylinder 18 and the sliding bearing, effectively blocking the heat transfer of the material inside the cement mill cylinder 18 by separating the cement mill cylinder 18 and the bearing 16 from direct contact, thereby reducing the operating temperature of the sliding bearing. The heat-insulating component 1 mainly includes a support frame 2 fixedly connected to the outer wall of the cement mill cylinder 18 and an annular frame 3 slidably connected to the bearing 16. The diameter of the annular frame 3 is larger than the diameter of the cement mill cylinder 18. It is connected to the cement mill cylinder 18 through the support frame 2 and replaces the direct contact between the cement mill cylinder 18 and the bearing 16, thus achieving the aforementioned blocking of the heat transfer of the material inside the cement mill cylinder 18.
[0027] Furthermore, such as Figure 4-7 As shown in the first embodiment of this utility model, the support frame 2 is configured as a plurality of connectors 4 evenly distributed circumferentially along the axis of the cement mill cylinder 18 between the cement mill cylinder 18 and the annular frame 3. The cross-section of the connector 4 can be rectangular or trapezoidal. A channel 6 communicating with the outside is formed between two adjacent connectors 4, allowing natural wind to pass through. When the heat of the material is transferred to the channel 6 along the cement mill cylinder 18, the airflow through the channel 6 carries away the heat on the connector 4, thereby reducing the heat transferred to the connector 4 along the annular frame 3 to the sliding part.
[0028] Furthermore, such as Figure 8-10 As shown, in the second embodiment of this utility model, the supporting frame 2 is configured as a plurality of annular bodies 5 arranged linearly along the axial direction of the cement mill cylinder 18. The spacing between two adjacent annular bodies 5 is determined by the width of the annular frame 3 and the number of annular bodies 5. Figure 10As shown, in this embodiment, three annular bodies 5 are provided, and all three annular bodies 5 share a common center with the annular frame 3 and the cement mill cylinder 18. Compared with the first embodiment, the annular bodies 5 surround the cement mill cylinder 18 and contact the cement mill cylinder 18 and the annular frame 3 at all angles, which can provide more solid support for the cement mill cylinder 18 and the annular frame 3. However, the heat dissipation channel 6 for the annular bodies 5 described in the first embodiment is missing. In order to achieve stable support for the cement mill cylinder 18 and the annular frame 3 while reducing the heat transfer along the annular bodies 5 to the sliding shoe, several through holes 7 are evenly opened on the annular bodies 5, so that the three annular bodies 5 are interconnected and connected to the outside world, allowing external airflow to pass through, thereby removing the heat on the annular bodies 5.
[0029] Furthermore, such as Figure 1-2 As shown, to reduce the heat transfer of the material along the cement mill cylinder 18 to the sliding shoe, a heat insulation plate 8 is installed on the inner wall of the cement mill cylinder 18. The heat insulation plate 8 can be made of nano-insulation material or precast cement insulation plate, etc. The heat insulation plate 8 can completely cover the cement mill cylinder 18, or it can be installed at the feed end and discharge end of the cement mill cylinder 18 (e.g., ...). Figure 10 As shown in the figure, this can reduce the heat transfer of the material to the sliding part during the material processing. In order to increase the service life of the heat insulation plate 8, a wear-resistant plate 9 can be added to the outer wall of the heat insulation plate 8. The size of the wear-resistant plate 9 is the same as that of the heat insulation plate 8. The wear-resistant plate 9 can be made of high manganese steel, alloy steel or wear-resistant cast iron, etc.
[0030] Furthermore, such as Figure 1-2 As shown, similar to the prior art, this utility model also adds a cooling component based on the above improvements, such as... Figure 4-10 As shown, the cooling component has the same structure as the cooling component in the prior art, so I will not go into too much detail here. Its main function is to cool the roller 16 and remove the heat from the roller 16. With the cooperation of the heat insulation component 1, it can effectively reduce the operating temperature of the sliding track, thereby further reducing the probability of cement mill failure.
