Abstract

This invention discloses a rotary feeder specifically for calcining furnaces, comprising a calcining furnace, a base plate fixedly welded to the outer surface of the calcining furnace, a drive mechanism mounted on the base plate, and a feeding mechanism connected to the drive mechanism and positioned corresponding to the feed inlet of the calcining furnace. This rotary feeder for calcining furnaces, through the cooperation of the drive mechanism and the feeding mechanism, transforms the feeding process from manual forklift feeding to automatic rotary feeding. This not only significantly reduces labor costs and improves feeding efficiency, but also effectively reduces dust leakage because the entire process takes place within a relatively enclosed pipeline, making it more environmentally friendly. Furthermore, when not in operation, the feeder can be moved away from the furnace opening, avoiding high-temperature baking and extending the equipment's service life. It also enables more convenient and precise automatic feeding operations within specific process time windows.

Description

Technical Field

[0001] This invention relates to the field of aluminum ash resource utilization technology, and in particular to a rotary feeder for calcining furnaces. Background Technology

[0002] In the process of aluminum ash resource utilization, aluminum ash and other materials need to be quantitatively and regularly added to the calcining furnace for high-temperature calcination. Traditional processes often use manual forklift feeding, which is not only labor-intensive and inefficient, but also easily generates dust during the feeding process, causing adverse effects on the environment and operators.

[0003] Therefore, it is necessary to provide a new rotary feeder specifically for calcining furnaces to solve the above-mentioned technical problems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a rotary automatic feeding structure, which replaces the original manual forklift feeding with rotary automatic feeding, which can significantly reduce labor costs, reduce environmental pollution, and make feeding operations more convenient and accurate within a specific time period.

A bottom bearing is disposed between the bottom of the support tube and the bottom of the rotating spindle.

[0015] Compared with related technologies, the rotary feeder for calcining furnaces provided by this invention has the following advantages: This invention provides a rotary feeder specifically for calcining furnaces. Through the coordination of the drive mechanism and the feeding mechanism, it transforms the feeding process from manual forklift feeding to automatic rotary feeding.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] In the specific implementation process, such as Figures 1-2As shown, a rotary feeder for calcining furnaces is used in calcining furnace equipment within an aluminum ash resource utilization system. The rotary feeder for calcining furnaces includes a calcining furnace 1, with a base plate 2 fixedly welded to the outer side of the calcining furnace 1.

[0020] A drive mechanism is installed on the base plate 2 to provide rotational power. The drive mechanism includes a driver 3, a drive sprocket 4, a driven sprocket 5, a drive chain 6, a rotating spindle 7, a bottom bearing 8, a support tube 9, and a support rotating bearing 10. The driver 3 is a motor, which is fixedly mounted on the base plate 2. The support tube 9 is bolted to the base plate 2. The support tube 9 is vertically arranged and hollow inside, used to accommodate and support the rotating spindle 7. The rotating spindle 7 is rotatably inserted into the support tube 9. The bottom of the rotating spindle 7 forms a rotational support with the support tube 9 through the bottom bearing 8, and the top of the rotating spindle 7 forms a rotational support with the support tube 9 through the support rotating bearing 10. In this embodiment, the bottom bearing 8 is a deep groove ball bearing, which bears radial loads and ensures the centering of the bottom of the rotating spindle 7; the support rotating bearing 10 is a tapered roller bearing 11, which can simultaneously bear large radial and axial loads, suitable for the top of the rotating spindle 7 to bear the weight of the feeding mechanism and the impact of materials, ensuring the stability and reliability of the rotating spindle 7 operation.

[0021] A drive sprocket 4 is fixedly connected to the output shaft of the driver 3, and a driven sprocket 5 is fixedly connected to the bottom of the rotating main shaft 7. The drive sprocket 4 and the driven sprocket 5 are connected by a drive chain 6. When the driver 3 is started, its output shaft drives the drive sprocket 4 to rotate. The drive sprocket 4 transmits power to the driven sprocket 5 through the drive chain 6, thereby driving the rotating main shaft 7 to rotate smoothly around its own axis inside the support tube 9.

[0022] A feeding mechanism is fixedly connected to the top of the rotating spindle 7, and the feeding mechanism rotates synchronously with the rotating spindle 7. The feeding mechanism includes a feeding nozzle 11, a discharging pipe 12, and a discharging nozzle 13. The discharging pipe 12 is an inclined pipe, fixedly connected to the top of the rotating spindle 7. The feeding nozzle 11 is connected to the high end of the discharging pipe 12, and the discharging nozzle 13 is connected to the low end. The axis of the feeding nozzle 11 coincides with the axis of the rotating spindle 7. This coaxiality allows the impact force of the material entering to be transmitted along the axis of the rotating spindle 7, avoiding the generation of off-center load torque and improving the service life of the rotating spindle 7. The inclined design of the discharging pipe 12 allows the material to form a natural drop using its own gravity, achieving smooth material conveying without the need for an additional power unit, resulting in a simple and energy-saving structure.

[0023] During non-feeding periods, the feeding mechanism rotates to the feeding position (the side facing away from the feed inlet of the calcining furnace 1) under the control of the drive mechanism. This avoids heat radiation from the high-temperature furnace opening onto the feeder body and facilitates other operations. When material needs to be added to the calcining furnace 1, the control system sends a feeding signal, the drive 3 starts, and drives the rotating main shaft 7 to rotate through the transmission of the drive sprocket 4, drive chain 6, and driven sprocket 5. The rotating main shaft 7 drives the feeding pipe 12 and the feeding nozzle 13, which are fixedly connected to it, to rotate together. When the feeding mechanism rotates to the working position, the axis of the feeding nozzle 13 coincides with the axis of the feed inlet of the calcining furnace 1, and the feeding nozzle 13 is aligned with the feed inlet of the calcining furnace 1. Subsequently, the material enters the feeding pipe 12 through the feeding nozzle 11. Under the natural drop of the inclined feeding pipe 12, the material is automatically conveyed towards the feeding nozzle 13 by gravity and finally falls from the feeding nozzle 13 into the feed inlet of the calcining furnace 1, completing one automatic feeding process. After feeding is completed, the driver 3 reverses again or rotates the feed tube 12 back to the feeding position, waiting for the next feeding command.

The specific connection methods of each component adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming, which is common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, this application document will not explain the control method and circuit connection in detail, and will not be described in detail here.
