Description

Technical Field

[0001] This utility model relates to the field of white fused alumina production technology, specifically to a lifting device for white fused alumina production. Background Technology

[0002] The lifting device for white fused alumina production is a specialized mechanical device used in the smelting and subsequent processing of white fused alumina to achieve vertical / inclined conveying of raw materials, intermediate products, or finished products. Its core function is to solve the problem of "material transfer height difference" in various stages of white fused alumina production, connecting crushing, smelting, screening, grading, and storage processes. It is a key auxiliary device to ensure production continuity and improve efficiency. The Z-type bucket elevator is a continuous conveying device used for vertical or inclined conveying of bulk materials. Its running trajectory is "Z"-shaped, combining the characteristics of horizontal and vertical lifting. It is suitable for working conditions that require multi-directional conveying and can be used for efficient and clean transfer of raw materials in white fused alumina production.

[0003] In the current production process of white fused alumina, if the particle size is fine and the moisture content is high, it is easy to adhere to the inner wall of the bucket of the bucket elevator. Especially when the white fused alumina raw material contains a certain amount of moisture, the moisture will cause the material particles to stick together, increasing the adhesion between the material and the bucket wall, thus forming a material accumulation layer, which will affect the conveying efficiency and even cause blockage.

[0015] Please see Figure 1-3 A lifting device for white fused alumina production includes a device body 1, an inlet 2 and an outlet 3 respectively provided on the device body 1, a chain 4 movably provided inside the device body 1 through multiple sets of sprockets, multiple sets of hoppers 5 provided on the chain 4, and a cleaning mechanism provided on the device body 1 for removing materials adhering to the inner wall of the hoppers 5. The cleaning mechanism includes a blower 8 and an air duct 10 that cooperates with the blower 8 and can deliver cleaning air into the hoppers 5. The main body 1 of the device serves as the core load-bearing frame of the entire lifting device, providing installation references and protective space for all components such as the feed inlet 2, discharge outlet 3, chain 4, hopper 5, and cleaning mechanism. It also defines the conveying path of the white fused alumina material. The feed inlet 2 is the only entrance for the white fused alumina raw material into the device. Its opening size and feeding angle must be adapted to the volume and operating speed of the hopper 5 to ensure that the material falls evenly and without accumulation into the hopper 5, laying the foundation for subsequent conveying. The discharge outlet 3 is the outlet for the lifted white fused alumina material to leave the device. Its location typically corresponds to the unloading area of ​​the hopper 5, ensuring the hopper 5 can rotate. During unloading, the material can fall completely into the discharge port 3, avoiding residue and spillage, and ensuring conveying efficiency. The chain 4 is the traction transmission component of the hopper 5. It achieves cyclic movement by cooperating with multiple sets of sprockets. Its two ends are fixedly connected to the hopper 5, which can drive multiple sets of hoppers 5 to move synchronously along the internal path of the main body 1 of the device, thereby realizing the continuous lifting of white fused alumina material. The hopper 5 is the core component for directly loading and transferring white fused alumina material. Multiple sets of hoppers 5 are evenly distributed along the chain 4. After receiving the material at the inlet 2, they rise with the chain 4 to the top of the main body 1 of the device, and the material is unloaded into the discharge port 3 by flipping or centrifugal force.

[0016] Please see Figure 2 and Figure 3 The main body 1 of the device is provided with an external mounting shell 6. Inside the mounting shell 6 are an air outlet box 7, an air inlet box 9, and a blower 8. The air outlet and air inlet of the blower 8 extend into the air outlet box 7 and air inlet box 9, respectively. An air duct 10 is fixedly installed inside the main body 1, with one end connected to the air outlet of the air outlet box 7. Multiple sets of pipes 11 are installed on the air duct 10, and multiple sets of air jet nozzles 12 are installed on the pipes 11 to spray cleaning air onto the inner wall of the hopper 5. A lead screw is rotatably installed inside the main body 1. 13. The main body 1 of the device is provided with a drive motor 15 whose output end is fixedly connected to one end of the lead screw 13. The lead screw 13 is engaged with a lead screw nut 14. The lead screw nut 14 is provided with a suction pipe 16 that can be limited to move. The suction pipe 16 is provided with multiple suction ends 17 for cleaning the inner bottom of the main body 1 of the device. The air inlet of the suction pipe 16 is provided with a retractable hose 18. One end of the retractable hose 18 is connected to the air inlet of the air inlet box 9. The air inlet of the air inlet box 9 is provided with a filter cartridge 19. Mounting housing 6 serves as an auxiliary protection and installation structure outside the main body 1 of the device, providing an independent and enclosed installation space for the air outlet box 7, air inlet box 9, and blower 8. The air outlet box 7 acts as a "transfer and buffer structure" between the blower 8's outlet and the duct 10. On one hand, it receives the high-pressure airflow output by the blower 8, stabilizing the airflow pressure through internal channels to prevent uneven airflow from the nozzle 12 due to airflow fluctuations. On the other hand, it precisely connects to the duct 10 through its outlet, efficiently delivering the high-pressure airflow to the duct 10, providing a stable air source for subsequent cleaning of the inner wall of the hopper 5. The blower 8 is the power core of the cleaning mechanism, possessing bidirectional airflow driving capability. Its outlet delivers high-pressure cleaning airflow to the air outlet box 7, providing power for the nozzle 12 to remove materials adhering to the inner wall of the hopper 5. Its inlet, through air intake... The air inlet box 9 generates negative pressure, providing suction for residual materials at the bottom of the main body 1 of the suction pipe 16, and simultaneously achieving the linkage of "clean airflow output" and "residual material recovery" to improve cleaning efficiency. The air inlet box 9 receives the dust-laden airflow drawn in by the suction pipe 16 through the retractable hose 18. The internal filter cartridge 19 can filter the white corundum dust in the airflow (such as fine powder falling off the hopper 5 and residual material accumulated at the bottom), preventing dust from entering the fan 8 and causing internal wear. The pipe 11 is a "branch connection structure" between the air duct 10 and the air nozzle 12. Multiple sets of pipes 11 are evenly distributed along the length of the air duct 10, and their length and angle can be adjusted according to the spacing and size of the hoppers 5 to ensure that the air nozzle 12 can be accurately aligned with the inner wall of the hopper 5, avoiding airflow waste, and simultaneously achieving the cleaning of all The hopper 5 is fully cleaned using the air nozzle 12, which directly removes materials adhering to the inner wall of the hopper 5. The nozzle's spray direction must be precisely aimed at areas prone to adhesion on the inner wall of the hopper 5 (such as the bottom and corners of the hopper). By spraying high-pressure cleaning air, the airflow impact force peels away residual white corundum materials (such as fine powder clumps and adhering small particles) from the inner wall of the hopper 5, preventing the formation of a material accumulation layer and ensuring the hopper 5's loading capacity and thorough unloading. The lead screw 13 is the transmission component that drives the suction pipe 16. It is rotatably installed inside the main body 1 and fixedly connected to the output end of the drive motor 15. Driven by the drive motor 15, it achieves forward and reverse rotation. Its external thread meshes with the lead screw nut 14, converting the rotational motion of the drive motor 15 into the linear motion of the lead screw nut 14. This causes the suction pipe 16 to move back and forth along the bottom of the main body 1, expanding the cleaning range. The suction pipe 16 is the "main pipe" for adsorbing residual materials at the bottom of the main body 1. Driven by the screw nut 14, it moves back and forth along the bottom. The pipe body needs to be adapted to the width of the bottom of the main body 1. At the same time, it expands the adsorption range through multiple suction ends 17, sucking in the white corundum residue accumulated at the bottom (such as the material peeled off by the nozzle 12 and the material spilled from the hopper 5) into the pipe. Then, it is transported to the air inlet box 9 through the retractable hose 18 to realize the recovery of residual materials and the cleaning of the bottom. The retractable hose 18 can extend and retract synchronously with the reciprocating movement of the suction pipe 16 to avoid the pipe from being pulled and broken due to the movement of the suction pipe 16. The filter cartridge 19 can filter the dust-laden airflow transported by the suction pipe 16.The system traps white corundum dust particles (such as micro powder and fine particles) in the airflow, allowing only clean air to enter the fan.

[0017] Working principle: During operation, white fused alumina raw material enters the main body 1 of the device through the feed inlet 2. The hopper 5, driven by the chain 4, receives the material at the bottom and moves upwards along the internal path of the main body 1 with the chain 4. When the hopper 5 reaches the top of the main body 1, it discharges the material into the discharge outlet 3 through tilting or centrifugal force, completing the vertical lifting and conveying to downstream equipment. After the hopper 5 completes unloading and is in an inverted state, the cleaning mechanism starts simultaneously. The high-pressure airflow generated by the blower 8 is buffered and stabilized by the air outlet box 7, and then distributed to each group of pipes 11 through the air duct 10, finally exiting through the jet nozzle 1. 2. The airflow is directed to the inner wall of the hopper 5, and the airflow impact force is used to peel off the residual adhering material. At the same time, the drive motor 15 drives the lead screw 13 to rotate, so that the lead screw nut 14 drives the dust suction pipe 16 to move back and forth along the bottom of the main body of the device 1. The peeled residual material and scattered material are sucked in through the dust suction end 17 and transported to the air inlet box 9 through the telescopic hose 18. After being filtered by the filter cartridge 19, the residual material is recovered. The clean air is discharged through the fan 8. The chain 4 continuously drives the hopper 5 to circulate. The material lifting and cleaning process are carried out simultaneously, forming a continuous closed loop of "lifting-unloading-cleaning-lifting".
