Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a raw material roller pressing device. Background Art

[0002] Raw material rolling is a key process in cement production line, which is mainly used to mix and compact the raw materials required for cement production for further processing and sintering. In the initial stage of raw material rolling, various raw materials are mixed together. These raw materials usually include limestone, clay, iron ore, etc. The mixed raw materials are called "raw materials". After mixing, the raw materials enter the roller press. The roller press usually consists of one or more pairs of rollers, which squeeze and grind the raw materials through pressure. This helps to mix various raw materials and compress them into fine particles. In the roller press, the raw materials are squeezed by high pressure to make them into uniform blocks. This helps to further process the raw materials and ensure uniformity and stability in subsequent process steps. Raw material rolling is crucial to the efficiency and quality of cement production. Through this process, the raw materials are fully mixed and ground, ensuring uniformity and stability during the sintering process. This is crucial for the production of high-quality cement products. However, the existing raw material rolling equipment is in a continuous production state during production, so it is impossible to store more raw materials at one time. When the feeding equipment fails, production cannot continue, so it cannot meet the actual production needs. Utility Model Content

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A raw material rolling device comprises a bearing seat, a cylinder, a support seat and a pressure roller, wherein bearing seats are installed at both ends of the cylinder, a support seat is provided below the bearing seat, a transmission tooth is provided on the cylinder, and the cylinder is connected to the gears of an external motor and a synchronous belt through the transmission tooth, a rolling tooth is provided inside the cylinder, a pressure roller is installed inside the cylinder through the engagement of the rolling tooth, grooves are provided at both ends of the cylinder, and end covers are installed at both ends of the cylinder through the groove limit.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, a fixing plate is rotatably mounted on the end cover via a bearing.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] Reduce friction and wear: The design of the bearing rotation installation can reduce the friction between the fixed plate and the end cover, thereby reducing the wear during the operation of the device. The bearing can provide smooth rotational motion and reduce friction loss between parts.

[0010] Balanced device operation: The bearing rotation installation allows the fixed plate to rotate on the end cover in a balanced manner, which helps to keep the device in a balanced state during operation. Especially in the case of high-speed operation, this balance is crucial to the stability and safety of the equipment.

[0011] Improve the working efficiency of the device: The design of bearing rotation allows the fixed plate to rotate freely on the end cover, which can distribute the pressure more evenly and roll the raw material more effectively. In this way, the processing efficiency and quality of the device in the production process will be improved.

[0012] Extend the service life of parts: By rotating the fixing plate through the bearing, the wear caused by the fixing plate directly contacting the end cover can be avoided, and the service life of the fixing plate can be extended. In this way, the frequency of parts replacement is reduced, and maintenance costs and downtime are reduced.

[0013] Easy maintenance and replacement: If the retaining plate needs to be maintained or replaced, the design of the bearing rotation installation makes this process easier. The bearing can be directly disassembled and then the retaining plate can be removed without involving a complicated disassembly process, saving maintenance time and labor costs.

[0014] Furthermore, both ends of the pressure roller are provided with limiting shafts, the pressure roller is installed on the fixing plate of the end cover through the limiting shafts, and the pressure roller is limitedly installed in the cylinder through the fixing plate.

[0015] The beneficial effects of adopting the above further scheme are:

[0016] Precise position control: The design of the limit axis can ensure that the position of the pressure roller is accurate on the fixed plate. In this way, the pressure roller will not be offset or shaken during operation, ensuring the accuracy and stability of the raw material roller pressing.

[0017] Prevent the roller from loosening: The roller is installed on the fixed plate through the limit shaft, so it will not loosen due to vibration or external force during operation. This ensures that the roller always stays in the correct position, effectively preventing problems that may occur during the operation of the equipment.

[0018] Reduce equipment vibration and noise: The pressure roller is installed inside the cylinder through the fixed plate. This design can effectively reduce the vibration and noise of the equipment during operation. After the pressure roller is fixed on the fixed plate, the connection between it and the cylinder is tighter, reducing the vibration and noise during the operation of the device.

[0019] Improve rolling effect: The design of the fixed plate limit installation makes the pressure distribution between the roller and the raw material more uniform. During the rolling process, the stable position of the roller can ensure that the raw material is subjected to more uniform and continuous pressure, improving the rolling effect and the processing quality of the raw material.

[0020] Easy to maintain and replace: When the roller needs to be maintained or replaced, the design of the limit shaft plug-in makes the process easier and faster. Simply dismantle the limit shaft to easily remove the roller for maintenance or replacement, saving maintenance time and labor costs.

Especially under high-speed operation or heavy-load conditions, this design can provide higher safety and reduce the occurrence of accidents.

[0022] Furthermore, the sizes of the roller pressing teeth on the inner surface of the cylinder and the outer surface of the pressing roller are matched.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] Uniform rolling effect: The matching of the rolling teeth means that the rolling teeth on the inner surface of the cylinder match the shape and size of the teeth on the outer surface of the roller. This design ensures that the roller can evenly transfer the pressure to the raw material when it passes through, achieving a uniform rolling effect.

[0025] Improve rolling quality: The appropriate rolling teeth size helps to ensure the quality and efficiency of the rolling process. The rolling teeth between the roller and the cylinder are closely matched, which can compact the raw material more effectively and improve the processing quality of the raw material during the rolling process.

[0026] Reduce the waste of raw materials: Due to the matching size of the roller teeth, the raw materials can be better compacted during the rolling process, reducing the waste of raw materials. The uniform thickness and density of the raw materials after rolling can reduce the unevenness and waste generation in subsequent processing.

[0027] Reduced energy consumption: The design of roller teeth with matching size can reduce the resistance of raw materials during rolling. This means that the roller needs less energy to compact the raw materials, which reduces energy consumption and meets the requirements of energy conservation and emission reduction.

[0028] Extend the service life of the equipment: The appropriate roller tooth size can reduce the friction and wear between the roller and the cylinder. The good fit between the roller and the cylinder reduces the wear during the rolling process and extends the service life of the equipment.

[0029] Improve work efficiency: The matching size of the roller teeth can ensure the consistency and stability of the raw material during the rolling process. In this way, the equipment can maintain a stable working state during operation, improving production efficiency and processing speed.

[0030] Reduce maintenance costs: The design of matching roller teeth can reduce the wear of rollers and cylinders, reducing the maintenance frequency and repair costs of equipment. This is a considerable saving for enterprises and also reduces downtime in the production process.

[0031] Furthermore, the end cover is connected and fixed to the cylinder body by bolts.

[0032] The beneficial effects of adopting the above further scheme are:

[0033] Solid structure: The end cover is connected and fixed to the cylinder body by bolts. This connection method can ensure the solid and stable structure of the whole device.

The bearing seats 1 are installed at both ends of the cylinder 3, and the support seat 4 is arranged below the bearing seat 1. A large amount of raw materials can be stored in the cylinder 3 at one time. The cylinder 3 is provided with a transmission tooth 2, and the cylinder 3 is connected to the gear of an external motor and a synchronous belt through the transmission tooth 2. The cylinder 3 is provided with a rolling tooth 7 inside. The size of the rolling tooth 7 on the inner surface of the cylinder 3 and the outer surface of the pressure roller 6 is adapted. The size adaptation of the rolling tooth 7 means that the shape and size of the rolling tooth 7 on the inner surface of the cylinder 3 and the teeth on the outer surface of the pressure roller 6 match. Such a design can ensure that when the raw material passes, the pressure roller 6 can evenly transfer the pressure to the raw material, so as to achieve a uniform rolling effect. The size of the adapted rolling tooth 7 helps to ensure the quality and efficiency in the rolling process. The rolling tooth 7 between the pressure roller 6 and the cylinder 3 is tightly matched, which can more effectively compact the raw material and improve the processing quality of the raw material in the rolling process. Since the size of the roller teeth 7 is adapted, the raw material can obtain a better compaction effect during the rolling process, reducing the waste of raw material. The uniform thickness and density of the raw material after rolling can reduce the unevenness and waste generation in subsequent processing. The design of the roller teeth 7 with the size adaptation can reduce the resistance of the raw material during the rolling process. This means that the roller 6 requires less energy to compact the raw material, reducing energy consumption and meeting the requirements of energy conservation and emission reduction. The adapted size of the roller teeth 7 can reduce the friction and wear between the roller 6 and the cylinder 3. The good fit between the roller 6 and the cylinder 3 reduces the wear during the rolling process and extends the service life of the equipment. The matching size of the roller teeth 7 can ensure the consistency and stability of the raw material during the rolling process. In this way, the equipment can maintain a stable working state during operation, improving production efficiency and processing speed. Since the design of the roller teeth 7 with the size adaptation can reduce the wear of the roller 6 and the cylinder 3, the maintenance frequency and maintenance cost of the equipment are reduced. This is a considerable saving for the enterprise, and it also reduces the downtime in the production process. The inside of the cylinder 3 is equipped with a pressure roller 6 through the meshing of the roller pressing teeth 7.

The pressure roller 6 is installed on the fixed plate 9 of the end cover 10 through the limit shaft 8. The pressure roller 6 is installed in the cylinder 3 through the fixed plate 9. The design of the limit shaft 8 can ensure that the position of the pressure roller 6 is accurate on the fixed plate. In this way, the pressure roller 6 will not be offset or shaken during operation, ensuring the accuracy and stability of the raw material rolling. The pressure roller 6 will not loosen due to vibration or external force during operation when working by plugging and installing it on the fixed plate through the limit shaft 8. In this way, the pressure roller 6 can always be kept in the correct position, effectively preventing problems that may occur during the operation of the equipment. The pressure roller 6 is installed in the cylinder 3 through the fixed plate. This design can effectively reduce the vibration and noise of the equipment during operation. After the pressure roller 6 is fixed on the fixed plate, the connection between the pressure roller 6 and the cylinder body 3 is tighter, which reduces the vibration and noise during the operation of the device.The design of the fixed plate limit installation makes the pressure distribution between the pressure roller 6 and the raw material more uniform. During the rolling process, the stable position of the pressure roller 6 can ensure that the raw material is subjected to more uniform and continuous pressure, improving the rolling effect and the processing quality of the raw material. When the pressure roller 6 needs to be maintained or replaced, the design of the limit shaft 8 plug-in makes this process simpler and faster. Only by disassembling the limit shaft 8, the pressure roller 6 can be easily removed for maintenance or replacement, saving maintenance time and labor costs. The pressure roller 6 is double fixed by the limit shaft 8 and the fixed plate, making the entire device more stable and reliable during operation. Especially under high-speed operation or heavy-load conditions, this design can provide higher safety and reduce the occurrence of accidents. Grooves 5 are provided at both ends of the cylinder 3, and end covers 10 are installed at both ends of the cylinder 3 through the groove 5. The end cover 10 is connected and fixed to the cylinder 3 by bolts. The end cover 10 is connected and fixed to the cylinder 3 by bolts. This connection method can ensure that the structure of the entire device is firm and stable. In the vibration and shock that may occur during the raw material rolling process, the end cover 10 will not loosen or shift, ensuring the stability of the equipment during operation. The bolt connection design makes it relatively easy to disassemble and install the end cover 10 and the cylinder 3. Maintenance personnel can easily remove the end cover 10 by removing the bolts to perform equipment inspection and maintenance work. Such a convenient maintenance process can reduce maintenance time and improve production efficiency. If it is necessary to replace the parts of the end cover 10 or the cylinder 3, such as sealing rings, bearings, etc., the bolt connection design makes this process easier. Only the corresponding bolts need to be removed to easily replace the required parts. The bolt connection method greatly reduces the cost of maintenance and replacement of parts. No complicated disassembly process and special tools are required. Only common bolt tools are needed to perform maintenance and replacement, saving maintenance costs. The end cover 10 is connected and fixed to the cylinder 3 by bolts. This strong connection method improves the safety of the device. It ensures that the end cover 10 will not fall off or shift due to accidents or external forces during the production process, thereby reducing potential safety hazards. The bolted connection structure makes the connection between the end cover 10 and the cylinder 3 tighter, increasing the overall stability of the device. Under high-speed operation or heavy-load conditions, this stable connection can effectively reduce the vibration and shaking of the device, ensuring stable production. The end cover 10 is rotatably mounted with a fixed plate 9, and the design of the bearing rotation installation can reduce the friction between the fixed plate and the end cover 10, thereby reducing the wear generated during the operation of the device. The bearing can provide smooth rotational motion and reduce the friction loss between parts. The bearing rotation installation allows the fixed plate to rotate on the end cover 10 in a balanced manner, which helps to maintain the balance of the device during operation. Especially in the case of high-speed operation, this balance is crucial to the stability and safety of the equipment. The bearing rotation design allows the fixed plate to rotate freely on the end cover 10, which can distribute the pressure more evenly and perform more effective rolling processing on the raw material.In this way, the processing efficiency and quality of the device in the production process will be improved. By rotating the mounting plate on the bearing, the wear caused by the direct contact between the mounting plate and the end cover 10 can be avoided, and the service life of the mounting plate can be extended. In this way, the frequency of parts replacement is reduced, and the maintenance cost and downtime are reduced. If the mounting plate needs to be maintained or replaced, the design of the rotating mounting of the bearing makes this process easier. The bearing can be directly disassembled and then the mounting plate can be removed without involving a complicated disassembly process, saving maintenance time and labor costs.
