Description

Technical Field

[0001] The present invention belongs to the technical field of carbon for aluminum, and particularly relates to an automatic sampling method for carbon bulk materials. Background Art

[0002] As one of the main raw materials for carbon materials used in aluminum production, carbon bulk materials have an important impact on the development of the carbon industry for aluminum, and can drive the continuous development of the electrolytic aluminum industry. In recent years, due to the increasing requirements for environmental protection and the quality of carbon bulk materials, it has significantly affected the domestic electrolytic aluminum production capacity, and thus affected the demand for carbon bulk materials in the electrolytic aluminum industry. Therefore, it is self-evident the importance of sampling carbon bulk materials and detecting their performance indicators. Due to different processes for producing carbon bulk materials and different qualities of crude oil at home and abroad, the diversity of performance indicators of carbon bulk materials has been caused. During the production process, it is necessary to sample different bulk materials and test their performance. On the one hand, mixing can be carried out according to their performance indicators to achieve ideal performance indicators. On the other hand, it can also be tested whether their performance indicators meet national or factory production standards.

[0003] However, the traditional sampling method is manual sampling. Most carbon bulk materials are stored in bins and transported by enclosed trains or trucks, which makes it very difficult for manual sampling and greatly increases the risk of manual sampling. If an accident occurs, it will inevitably cause losses to personal safety and slow down production. There is currently no special tool for manual sampling, so the sampling efficiency is low. The crushing and screening after sampling are all manual operations to meet the sample standards required for inspection. Manual sampling will also pollute the workshop environment and it is difficult to control the spread of dust. Therefore, it is of great significance to develop an automatic sampling method for carbon bulk materials. Summary of the Invention

[0004] In view of the above-mentioned drawbacks and deficiencies of the prior art, the present invention provides an automatic sampling method for carbon bulk materials, the purpose of which is to automatically sample carbon bulk materials and reduce manual operations.

[0005] In order to achieve the above object, the main technical solutions adopted by the present invention include: An automatic sampling method for carbon bulk materials uses a spiral sampling device to extract raw materials from the carbon bulk materials in the transportation vehicle of carbon bulk materials. The raw materials extracted by the spiral sampling device are transported to a crusher by a belt conveyor. During the transportation by the belt conveyor, the raw materials are de-ironed by a magnetic separator. The crusher crushes the carbon bulk materials, and the crushed samples are sent to a splitter by a sample belt conveyor for subdivision. The subdivided carbon bulk materials enter a packaging machine for packaging, and the remaining carbon bulk materials are transported back to the transportation vehicle of carbon bulk materials through a waste belt conveyor.

[0006] Further, the spiral sampling device measures the extraction quantity.

[0007] Further, the crusher crushes the carbon bulk material to a particle size of less than or equal to 50 mm.

[0008] Further, the splitter subdivides the carbon bulk material into three ranges for packaging, namely less than or equal to 10 mm, 10 - 30 mm, and 30 - 50 mm.

[0009] Further, the packaging machine numbers the bulk material after packaging for distinction.

[0010] The beneficial effects of the present invention are as follows: The present invention can sample the carbon bulk material transported by automobile or train, with a high degree of automation, without manual operation for sampling, and can control the spiral sampling device to extract different amounts according to the different weight requirements of different bulk materials. The present invention is not only applicable to the automatic sampling of carbon bulk materials, but also applicable to industries and fields such as non-ferrous metallurgy that require sampling and analysis of bulk materials.

[0013] In order to better explain the present invention for easy understanding, the present invention will be described in detail below with reference to the drawings through specific embodiments.

[0014] As Figure 1As shown in the figure, the present invention provides an automatic sampling method for carbon bulk materials. A spiral sampling device 2 is used to extract raw materials from the carbon bulk materials in the carbon bulk material transport vehicle 1. The spiral sampling device 2 can directly extract the carbon bulk materials from the vehicle and measure the extraction quantity. The raw materials extracted by the spiral sampling device 2 are transported to a crusher 5 for crushing through a belt conveyor 3. During the transportation by the belt conveyor 3, iron filings are removed from the raw materials by a magnetic separator 4. The crusher 5 crushes the carbon bulk materials. The crusher 5 can crush large pieces of carbon bulk materials to meet the particle size requirements for experiments. Specifically, the crusher 5 crushes the carbon bulk materials to a particle size less than or equal to 50 mm. The crushed samples are sent to a splitter 7 through a sample belt conveyor 6 for subdivision. The splitter 7 can screen the crushed carbon bulk materials and subdivide them according to the required quantity. The subdivided carbon bulk materials enter a packaging machine 8 for packaging. The packaging machine 8 packs the carbon bulk materials into bags, marks and differentiates the bulk materials. Specifically, the splitter 7 subdivides the carbon bulk materials into three ranges for packaging, namely less than or equal to 10 mm, 10 - 30 mm, and 30 - 50 mm. The remaining carbon bulk materials are returned to the carbon bulk material transport vehicle 1 through a waste belt conveyor 9 for transportation.

[0015] The automatic sampling method for carbon bulk materials of the present invention samples, removes iron, crushes, screens, and packages the transported carbon bulk materials, comprehensively processes the bulk materials required in the carbon industry, and overall consideration brings great convenience to production operation.
