[0002] In industrial production, some pellets are mixed with ferrous metals, which are ferromagnetic substances. If the ferromagnetic substances in the pellets are not removed, it will not only pollute the pellets, but also have many negative effects on the downstream products of the pellets, and may even cause safety accidents. Therefore, removing the ferromagnetic substances in the pellets is an important pellet purification process.

[0003] The cleaning devices used in actual production are not ideal for removing ferromagnetic materials from granular materials, or even have no removal effect. In addition, the process of cleaning the separated ferromagnetic materials is cumbersome, and the ease of use of such equipment is not optimistic under many working conditions.

DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0018] like Figure 1-4 As shown, the present invention provides an online self-cleaning material cleaning device for removing ferromagnetic materials, including the basic structure of a general material cleaning equipment, and also provided with a ferromagnetic material sorting unit. The granular material enters the ferromagnetic material sorting unit and leaves the unit after a period of time, and the ferromagnetic material particles or ferromagnetic dust in the granular material are sorted out to achieve purification of the granular material; the ferromagnetic material sorting unit structure of the material cleaning equipment includes: a primary strong magnetic field 4, a secondary strong magnetic field 6, a drag unit dust cover 15, a drag element 16; a primary scraper or scraping brush component 13, a secondary scraper or scraping brush component 11, a slag holding component 10, etc.

[0019] Among them, the primary strong magnetic field 4 and the secondary strong magnetic field 6 are the core technical components of the ferromagnetic material sorting unit. The strength of the magnetic field determines the effect of removing the ferromagnetic material in the granular material. In the present invention, the strong magnetic field generating component is required to be a permanent strong magnet with a magnetic induction intensity exceeding 2500 Gauss. The magnetic field strength of the primary strong magnetic field 4 and the secondary strong magnetic field 6 exceeds 2500 Gauss, which will not only produce a good removal effect on the exposed ferromagnetic material in the granular material, but also have a significant removal effect on some ferromagnetic particles embedded in the granular material particles.

[0020] In addition, the primary strong magnetic field 4 and the secondary strong magnetic field 6 can be movable or rotatable, which is convenient for disassembly and debugging of the equipment after installation. The fixing method of the primary strong magnetic field 4 and the secondary strong magnetic field 6 at both ends and the housing of the cleaning equipment adopts bar screw holes, and the position adjustment and disassembly of the strong magnetic field can be met by adjusting the fixing position of the bolts.

[0021] Furthermore, in order to ensure that the material cleaning device can remove the ferromagnetic material in the granular material, two important factors must be ensured. One is to ensure that the granular material is close to the strong magnetic field and there is no obstruction. The other is to ensure that the granular material can stay around the strong magnetic field for a sufficient time. The present invention is mainly reflected in the embodiment that the distribution plate 14 is relatively close to the first-level granular material baffle 3, and the distribution plate 14 is close to the first-level strong magnetic field 4; in this way, when the granular material moves downward, a thinner granular material layer can be formed on the part of the distribution plate 14 close to the first-level strong magnetic field 4; in the example, the material cleaning device is provided with a first-level strong magnetic field 4 and a second-level strong magnetic field 6, in order to increase the residence time of the granular material in the overall device in the strong magnetic field environment.

[0022] As is known to all, after being attracted by a strong magnetic field, ferromagnetic substances will adhere to the surface of the primary strong magnetic field 4 and the secondary strong magnetic field 6, which will have an adverse effect on the continuous operation of the subsequent magnetic field. Therefore, timely cleaning of the surface ferromagnetic substances of the primary strong magnetic field 4 and the secondary strong magnetic field 6 is very important to ensure the effective operation of the entire device. Therefore, the lower surface of the primary strong magnetic field 4 and the secondary strong magnetic field 6 is tangentially contacted with the primary scraper or scraping brush component 13 and the secondary scraper or scraping brush component 11; the primary scraper or scraping brush component 13 and the secondary scraper or scraping brush component 11 are fixedly supported by the primary elastic element 5 and the secondary elastic element 7, respectively. In this way, the primary scraper or scraping brush component 13 and the secondary scraper or scraping brush component 11 can clean the surface ferromagnetic substances of the primary strong magnetic field 4 and the secondary strong magnetic field 6 in time.

[0023] The cleaned ferromagnetic materials fall into the slag forming part 10 at the lower part of the material cleaning device, and are cleaned regularly in actual production, which is convenient and efficient.

[0024] Next, this example is explained from the logic of the entire material cleaning device operation process: the granular material mixed with ferromagnetic substances enters the material cleaning device from the granular material inlet 1, and a large amount of granular material falls on the material distribution plate 14. After being adjusted by the primary granular material baffle 3, the granular material moves to the primary strong magnetic field 4 in a thinner layer. When the granular material contacts the primary strong magnetic field 4, on the one hand, the primary granular material baffle 3 prevents the granular material from falling into the edge of the material cleaning device housing; on the other hand, the primary strong magnetic field 4 attracts the ferromagnetic substances in the granular material that it contacts to its surface, and takes the ferromagnetic substances away from the moving side of the granular material as it rotates. When the ferromagnetic substances are separated from the granular material by a short distance, the ferromagnetic substances on the surface of the primary strong magnetic field 4 will be cleaned and dropped by the primary scraper or scraping brush component 13. To prevent the primary scraper or scraping brush component 13 from being worn and unable to stably contact the surface of the primary strong magnetic field 4, a primary elastic element 5 is used to fix and support the primary scraper or scraping brush component 13. The ferromagnetic material falling after separation is affected by the primary separation baffle 12 and will not come into contact with the granular material again, nor will it fall onto the surface of the secondary strong magnetic field 6, but will smoothly enter the sediment component 10.

[0025] As the primary strong magnetic field 4 rotates, the granular material continues to move downward into the granular material channel formed by the primary separation baffle 12 and the secondary granular material baffle 9, and then the granular material contacts the secondary strong magnetic field 6. The secondary strong magnetic field 6 again attracts and separates the ferromagnetic material still existing in the granular material it contacts. The ferromagnetic material is attracted to the surface of the secondary strong magnetic field 6 and rotates with it. When it contacts the secondary scraper or scraper brush component 11, the ferromagnetic material is hung and separated from the secondary strong magnetic field 6. Similarly, in order to prevent the secondary scraper or scraper brush component 11 from being worn and unable to stably contact the surface of the secondary strong magnetic field 6, a secondary elastic element 7 is used to fix and support the secondary scraper or scraper brush component 11. The ferromagnetic material that falls after separation is affected by the secondary separation baffle 8 and will no longer contact the granular material, but will smoothly enter the sediment component 10.

[0026] Finally, the clean granular material processed by the material cleaning device flows out through the granular material outlet.

[0027] In the process of removing ferromagnetic materials from the entire cleaning device, the cleaning device can be designed into a polygon according to the working conditions. The above example shows a cleaning device with a quadrilateral top view, and two-level ferromagnetic material separation units are set in the plane where each side is located. The strong magnetic field adopts a cylindrical structure. In this case, the strong magnetic field is rolled with the axis as the reference, which can maximize the action time of the ferromagnetic material in the granular material and the strong magnetic field. At the same time, the volume of the equipment can be relatively reduced. The stronger the magnetic force of the strong magnetic field, the more difficult it is to clean and separate the ferromagnetic material attracted by its surface. Therefore, in this case, the strong magnetic field is designed to be a cylindrical shape with a notch groove 18. This notch groove 18 is a designed magnetic field blind area. The magnetic field blind area can be seen from the structural schematic diagram of the strong magnetic field. The existence of the blind area is mainly to improve the slag removal ability of the scraper or scraping brush components 11 and 13. From the appearance diagram of the cleaning device, it can be seen that the drag unit is composed of a dust cover 15 and a drag element 16, which is a component that provides power for the rotation or movement of the strong magnetic field. In addition, in this case, in order to facilitate the user to understand the operation of the material cleaning device, windows 17 are provided on the four upper sides of the material cleaning device.

[0028] In summary, the present invention is explained by introducing an example. According to the contents described in the claims, other examples conceived by those skilled in the art still belong to the protection scope of the present invention.
