Description

Technical Field

[0001] The present invention relates to the technical field of electrolytic aluminum, and in particular to a highly efficient and fully automatic aluminum oxide conveying method and system. Background Art

[0002] With the rapid development of my country's aluminum electrolysis industry, aluminum production capacity is increasing. Alumina, as one of the necessary raw materials for electrolytic aluminum, consumes a large amount of alumina raw materials during the production process. Therefore, the transportation rate of alumina raw materials in the plant area is required to be relatively high. According to the situation of different electrolytic aluminum plants, alumina raw materials are generally transported to the electrolytic aluminum plant by road, rail and other means, and then the alumina is transported to the fresh alumina by the front loader + tipping platform. A front loader + tipping platform device can only be used for unloading a container or bagged alumina at the same time, so it is necessary to assemble several tipping devices at the same time to complete the alumina unloading operation within a certain period of time. This alumina unloading method will cause a lot of time and manpower cost resources to be wasted, and increase the use area of ​​the plant. At the same time, a large amount of dust will be released during tipping, which will indirectly pollute the internal environment of the plant area. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a highly efficient and fully automatic alumina conveying method and system, which utilizes the existing railway advantages 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 present invention adopts the following technical scheme: an efficient and fully automatic alumina conveying method, a container loaded with bulk alumina is transported to a unloading workshop, the unloading workshop is provided with a screw unloader, the screw unloader unloads the bulk alumina to a first transmission belt, the first transmission belt transports the bulk alumina to a feeding bucket elevator, the feeding bucket elevator transports the bulk alumina to a fresh alumina bin via a second transmission belt, the fresh alumina bin transports the fresh alumina to a discharging bucket elevator via a third transmission belt, the discharging bucket elevator transports the fresh alumina to the electrolysis workshop via a fourth transmission belt.

[0005] The second transmission belt, the third transmission belt and the fourth transmission belt are all replaced with pneumatic chutes.

[0006] The conveying system constituted by the above-mentioned efficient and fully automatic alumina conveying method includes a screw unloader, which is arranged in a unloading workshop. 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 a feeding bucket elevator. The feeding bucket elevator is connected to a fresh alumina bin through a second transmission belt, and the fresh alumina bin is connected to a discharging bucket elevator through a third transmission belt. The discharging bucket elevator is connected to the electrolysis workshop through a fourth transmission belt.

[0007] There are at least two of the third transmission belt, the discharge bucket elevator and the fourth transmission belt.

[0008] The width of the first transmission belt, the second transmission belt, the third transmission belt and the fourth transmission belt is 1.1-1.2 meters.

[0009] The spiral car unloading sweeper is an integrated fully automatic vertical spiral car unloading machine.

[0010] The feeding bucket elevator and the discharging bucket elevator are both wire belt bucket elevators.

[0011] Beneficial effects of the present invention: 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 aluminum smelter, and saves manpower and material resources by adopting a fully automated transportation method.

DETAILED DESCRIPTION

[0013] 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, rather than all the embodiments.

[0014] The technical solution of the present invention is described in detail with specific embodiments below. 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

[0015] 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 reach stacker and a tipping platform 1. However, one reach stacker and a tipping platform 1 can only be used to unload one container or bagged alumina at the same time. This method requires a lot of time and manpower, and increases the use 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.

[0016] like Figure 2 As shown, the present invention provides a high-efficiency and fully automatic alumina conveying method, characterized in that a container loaded with bulk alumina is transported to a discharge workshop 3, the discharge workshop 3 is provided with a screw unloader 4, the screw unloader 4 unloads the bulk alumina to a first transmission belt 5, the first transmission belt 5 transports the bulk alumina to a feeding bucket elevator 6, the feeding bucket elevator 6 transports the bulk alumina to a fresh alumina bin 8 through a second transmission belt 7, the fresh alumina bin 8 transports the fresh alumina to a discharge bucket elevator 10 through a third transmission belt 9, and the discharge bucket elevator 10 transports the fresh alumina to the electrolysis workshop through a fourth transmission belt 11.

[0017] The conveying system formed by the above-mentioned efficient and fully automatic alumina conveying method includes a screw 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. The side of the first transmission belt 5 is connected to the screw unloader 4, and one end of the first transmission belt 5 is connected to a feeding bucket elevator 6. The feeding bucket elevator 6 is connected to a fresh alumina bin 8 through a second transmission belt 7. The fresh alumina bin 8 is connected to a discharging bucket elevator 10 through a third transmission belt 9. The discharging bucket elevator 10 is connected to the electrolysis workshop through a fourth transmission belt 11.

[0018] In this embodiment, two spiral unloading sweepers 4 are arranged in parallel and at intervals, and the first transmission belts 5 are also two with opposite transmission directions and are connected to the feeding bucket elevator 6 together. The third transmission belt 9, the discharge bucket elevator 10 and the fourth transmission belt 11 are at least two.

[0019] 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. Example

[0020] In order to better avoid 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 avoids dust leakage, but also reduces the noise of the transmission process.

[0021] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments of 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.
