Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum, in particular to a high-efficiency fully automatic alumina conveying system. Background Art

[0002] With the rapid development of my country's aluminum electrolysis industry, aluminum production capacity is continuously increasing. Alumina, as one of the essential raw materials for electrolytic aluminum, consumes a large amount of raw alumina during production, necessitating a high rate of raw alumina transportation within the plant. Currently, alumina raw materials are typically transported to the plant by truck or rail, and then transported to fresh alumina using a reach stacker and a tilting platform. However, a single reach stacker and tilting platform can only unload one container or bag of alumina at a time, necessitating the simultaneous installation of several tilting devices to complete the unloading process within a specified timeframe. This method of unloading alumina wastes significant time, labor costs, and resources, increases plant floor space, and releases large amounts of dust during tipping, indirectly polluting the plant's internal environment. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a high-efficiency fully automatic alumina conveying system, which takes advantage of the existing railway to make alumina unloading and conveying more automatic and efficient, and to a certain extent reduce the cost of manpower and floor space.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a high-efficiency fully automatic alumina conveying system, including a screw unloader, which is arranged in a unloading workshop, and a first transmission belt is provided on one side of the unloading workshop. The side of the first transmission belt is connected to the screw unloader, and one end of the first transmission belt is connected to the feeding bucket elevator, and the feeding bucket elevator is connected to the fresh alumina bin through a second transmission belt. The fresh alumina bin is connected to the discharging bucket elevator through a third transmission belt, and the discharging bucket elevator is connected to the electrolysis workshop through a fourth transmission belt.

[0005] There are at least two of the third transmission belt, the discharge bucket elevator and the fourth transmission belt.

[0006] The second transmission belt, the third transmission belt and the fourth transmission belt are all replaced by pneumatic chutes.

[0007] The width of the first transmission belt, the second transmission belt, the third transmission belt and the fourth transmission belt is 1.1 to 1.2 meters.

[0008] The spiral car unloading sweeper is an integrated fully automatic vertical spiral car unloading machine.

[0009] The feeding bucket elevator and the discharging bucket elevator are both wire belt bucket elevators.

[0010] The beneficial effects of the present invention are as follows: compared with the prior art, the present invention avoids the process of unloading containers from train tracks and placing them on a tipping platform by using a front loader by applying a spiral unloading sweeper to the alumina transportation of an electrolytic aluminum plant, and saves manpower and material resources by adopting a fully automated transportation method.

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0016] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments. Example

[0017] like Figure 1 As shown, the existing alumina transportation method is to transport the alumina to the discharge hopper 2 and then to the fresh alumina bin by means of a front loader and a tilting platform 1. However, one front loader and a tilting platform 1 can only be used to unload one container or bagged alumina at a time. This method requires a lot of time and manpower, and increases the usable area of ​​the factory. At the same time, a large amount of dust will be released during tipping, which indirectly pollutes the internal environment of the factory.

[0018] like Figure 2As shown, the utility model provides a high-efficiency fully automatic alumina conveying system, including a spiral unloader 4, which is arranged in a unloading workshop 3. A first transmission belt 5 is provided on one side of the unloading workshop 3, and the side of the first transmission belt 5 is connected to the spiral unloader 4. One end of the first transmission belt 5 is connected to the feeding bucket elevator 6, and the feeding bucket elevator 6 is connected to the fresh alumina bin 8 through the second transmission belt 7. The fresh alumina bin 8 is connected to the discharge bucket elevator 10 through the third transmission belt 9, and the discharge bucket elevator 10 is connected to the electrolysis workshop through the fourth transmission belt 11.

[0019] In this embodiment, two spiral unloading sweepers 4 are arranged in parallel and spaced apart, and there are also two first transmission belts 5 with opposite transmission directions and connected to the feeding bucket elevator 6. The third transmission belt 9, the discharge bucket elevator 10 and the fourth transmission belt 11 are at least two.

[0020] Specifically, the width of the first transmission belt 5, the second transmission belt 6, the third transmission belt 9 and the fourth transmission belt 11 is 1.1 to 1.2 meters, the spiral unloader 4 is an integrated fully automatic vertical spiral unloader, and the feeding bucket elevator 6 and the discharging bucket elevator 10 are both wire belt bucket elevators.

[0021] Working principle: Containers loaded with bulk alumina are transported to the unloading workshop 3. The unloading workshop 3 is equipped with a screw unloader 4. The screw unloader 4 unloads the bulk alumina to the first transmission belt 5. The first transmission belt 5 transports the bulk alumina to the feeding bucket elevator 6. The feeding bucket elevator 6 transports the bulk alumina to the fresh alumina bin 8 through the second transmission belt 7. The fresh alumina bin 8 transports the fresh alumina to the discharge bucket elevator 10 through the third transmission belt 9. The discharge bucket elevator 10 transports the fresh alumina to the electrolysis workshop through the fourth transmission belt 11. Example

[0022] To better prevent dust leakage and improve the working environment, the second transmission belt 7, the third transmission belt 9, and the fourth transmission belt 11 are all replaced with pneumatic chutes. Compared with the belt transmission method, the pneumatic chute not only effectively prevents dust leakage but also reduces the noise during the transmission process.

[0023] In addition to the above-mentioned preferred embodiments, the present invention has other implementation methods. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
