Abstract
Description
Technical Field
[0001] This application relates to the technical field of material conveying devices, and in particular to a star-shaped feeder for conveying high-temperature materials. Background Technology
[0002] In white cement production, some intermediate products, such as ash and slag, have high temperatures. Ordinary feeding and unloading devices have poor adaptability to high-temperature environments and are easily damaged. Therefore, the industry typically uses star-shaped feeders for conveying high-temperature materials.
[0003] The existing star-shaped feeder mainly uses a drive motor to rotate the rotor impeller to discharge materials from the upper hopper. The rotor impeller and the main structure are mainly made of stainless steel or carbon steel, which can work normally in high-temperature environments below 1000℃.
[0004] However, during the use of existing star-shaped feeders, the drive motor often experiences lubricating oil evaporation in high-temperature environments, leading to damage to its internal components. This significantly affects the normal operation and service life of the equipment, and increases maintenance costs. Utility Model Content
[0005] To address the problems existing in the prior art, this application provides a star-shaped feeder for conveying high-temperature materials.
[0006] This application provides a star-shaped feeder for conveying high-temperature materials, which adopts the following technical solution:
[0007] A star-shaped feeder for conveying high-temperature materials includes a hopper, a rotor impeller, a transmission rod, and a drive motor. The rotor impeller is rotatably disposed inside the hopper. The transmission rod is coaxially and fixedly connected to the rotor impeller and extends to the outside of the hopper. The drive motor is fixedly disposed on the hopper and the minimum distance between it and the rotor impeller is not less than 500 mm. The drive motor is provided with a transmission component for driving the transmission rod to rotate.
[0008] Optionally, support sleeves are fixedly installed on both sides of the hopper. The support sleeves are sleeved on the transmission rod. A sealing cover is fixedly installed at the end of the support sleeve away from the hopper. The support sleeve is connected to the sealing cover. An oil seal is installed inside the sealing cover to seal the gap between the transmission rod and the support sleeve.
[0009] Optionally, a bearing is also provided inside the sealing cover. The bearing is sleeved on the transmission rod, the inner ring of the bearing is fixedly connected to the transmission rod, and the outer ring of the bearing is fixedly connected to the sealing cover.
[0010] Optionally, support frames are also fixedly installed on both sides of the hopper, and the support frames are fixedly connected to the sealing cover located on the same side.
[0011] Optionally, the transmission assembly includes a driving gear, a driven gear, and a chain. The driving gear is coaxially and fixedly connected to the output shaft of the drive motor. The driven gear is coaxially and fixedly connected to the transmission rod. The chain is wound around the driving gear and the driven gear and meshes with the driving gear and the driven gear respectively.
[0012] Optionally, a protective cover is fixedly installed on the hopper, and the driving gear, driven gear and chain are all installed inside the protective cover.
[0013] Optionally, the inner wall of the protective cover is covered with a heat-insulating film.
[0014] Optionally, the protective cover is provided with an oil replenishment port, which is connected to an oil supply pipe for delivering lubricating oil to the surface of the chain.
[0015] In summary, this application includes at least one of the following beneficial technical effects:
[0016] 1. This application sets the minimum distance between the drive motor and the rotor impeller to not less than 500mm, thereby keeping the drive motor away from the high-temperature rotor impeller, avoiding the influence of the heat transfer temperature of the drive motor on the rotor impeller, reducing the problems of lubricating oil evaporation and high-temperature damage to internal components, ensuring normal operation of the equipment and extending its service life.
[0017] 2. This application effectively seals the gap between the transmission rod and the hopper by installing support sleeves on both sides of the hopper, with the support sleeves fitted onto the transmission rod, and an oil seal installed inside the sealing cover at the end of the support sleeve. Simultaneously, placing the oil seal inside the sealing cover, keeping it away from the rotor impeller, effectively reduces the impact of high-temperature dust.
[0018] 3. By placing the drive gear, driven gear, and chain inside the protective cover, this application can prevent external dust and impurities from entering the transmission components, thus ensuring the normal and stable operation of the transmission components. Attached Figure Description

Detailed Implementation
[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0026] This application discloses a star-shaped feeder for conveying high-temperature materials. (Refer to...) Figure 1 , 2 The system includes a hopper 1, a rotor impeller 2, a transmission rod 3, a drive motor 4, and a transmission assembly 5. The hopper 1 provides space for material storage. The rotor impeller 2 is rotatably mounted inside the hopper 1, facilitating the unloading of materials from the hopper 1. The transmission rod 3 is coaxially and fixedly connected to the rotor impeller 2, and both ends of the transmission rod 3 extend to the outside of the hopper 1, transmitting power to the rotor impeller 2. The drive motor 4 is fixed to the hopper 1 with a minimum distance of not less than 500mm from the rotor impeller 2. It then drives the transmission rod 3 to rotate through the transmission assembly 5. This keeps the drive motor 4 away from the high-temperature rotor impeller 2, preventing the drive motor 4 from being affected by the heat transfer temperature of the rotor impeller 2, reducing lubricating oil evaporation and high-temperature damage to internal components, ensuring normal operation of the equipment and extending its service life.
[0027] Reference Figure 2 The rotor impeller 2 is one of the core components of the feeder. It consists of a main shaft and multiple blades mounted on the side wall of the main shaft. The shape and number of blades can be designed according to the characteristics of the material and the conveying requirements. The rotor impeller 2 is also made of stainless steel or carbon steel to ensure that it will not deform or be damaged in high-temperature environments. The material above the rotor impeller 2 enters between the adjacent blades of the rotor impeller 2. Through the rotation of the rotor impeller 2, the material is transported to the bottom of the rotor impeller 2. Then, the material falls under the action of gravity and is discharged from the discharge port at the bottom of the hopper 1, thus achieving unloading.
[0028] Reference Figure 2 The transmission rod 3 serves to connect the rotor impeller 2 and the transmission assembly 5. It is generally a cylindrical metal rod with high strength and wear resistance. The transmission rod 3 passes through the main shaft of the rotor impeller 2 and is connected to the main shaft of the rotor impeller 2 by a key or coupling to ensure that the two rotate synchronously.
[0029] Reference Figure 2 , 3 Support sleeves 11 are fixedly installed on both sides of the hopper 1. The support sleeves 11 are adapted to the transmission rod 3 and are sleeved on the transmission rod 3, serving to support and protect the transmission rod 3. A sealing cover 12 is fixedly installed at the end of the support sleeve 11 away from the hopper 1. The support sleeve 11 and the sealing cover 12 are connected. An oil seal 13 is installed inside the sealing cover 12 to seal the gap between the transmission rod 3 and the support sleeve 11, thereby effectively sealing the gap between the transmission rod 3 and the hopper 1. Furthermore, placing the oil seal 13 inside the sealing cover 12, away from the rotor impeller 2, can effectively reduce the impact of high temperature dust on it.
[0030] Reference Figure 3 A bearing 14 is also provided inside the sealing cover 12 and on the side of the oil seal 13 away from the rotor impeller 2. The bearing 14 is sleeved on the transmission rod 3, with its inner ring fixedly connected to the transmission rod 3 and its outer ring fixedly connected to the sealing cover 12. The bearing 14 serves to support the transmission rod 3, and its arrangement makes the rotation of the transmission rod 3 smoother and reduces friction.
[0031] Reference Figure 1 Support frames 15 are fixedly installed on both sides of the hopper 1. The support frames 15 are fixedly connected to the sealing cover 12 located on the same side. The support frames 15 are generally made of steel and have good support strength. The support frames 15 enhance the stability of the sealing cover 12, enabling the sealing cover 12 to better support the transmission rod 3 and the bearing 14.
[0032] Reference Figure 2 , 4 The drive motor 4 is a geared motor and is bolted to the side wall of the hopper 1. The transmission assembly 5 includes a drive gear 51, a driven gear 52, and a chain 53. The drive gear 51 is coaxially and fixedly connected to the output shaft of the drive motor 4, the driven gear 52 is coaxially and fixedly connected to the transmission rod 3, and the chain 53 is wound around the drive gear 51 and the driven gear 52 and meshes with them respectively. When the drive motor 4 is working, it drives the drive gear 51 to rotate, which in turn drives the driven gear 52 to rotate via the chain 53, thereby causing the transmission rod 3 and the rotor impeller 2 to rotate.
[0033] Reference Figure 4 A protective cover 16 is fixedly installed on the hopper 1, and the drive gear 51, driven gear 52, and chain 53 are all housed inside the protective cover 16. The protective cover 16 protects the transmission assembly 5, preventing dust and debris from entering and extending its service life. The inner wall of the protective cover 16 is covered with a heat-insulating film, such as ceramic fiber heat-insulating film, which has excellent heat insulation properties and effectively blocks high-temperature transmission. The heat-insulating film reduces the impact of high temperatures on the transmission assembly 5, ensuring its normal operation.
[0034] Reference Figure 5 The protective cover 16 is also equipped with an oil replenishment port 161, which is connected to an oil supply pipe 162 for delivering lubricating oil to the surface of the chain 53. Through the oil replenishment port 161 and the oil supply pipe 162, lubricating oil can be delivered to the surface of the chain 53 in a timely manner, ensuring the normal operation and service life of the chain 53.
[0035] The implementation principle of a star-shaped feeder for conveying high-temperature materials in this application embodiment is as follows: by keeping the drive motor 4, oil seal 13 and bearing 14 away from the high-temperature rotor impeller 2, the drive motor 4, oil seal 13 and bearing 14 are not affected by the heat transfer temperature of the rotor impeller 2, thereby reducing the problems of lubricating oil evaporation and high-temperature damage to internal components, ensuring normal operation of the equipment and extending its service life.
[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
