However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device, and environment.

Detailed implementation mode

[0023] The following describes in detail a separator equipped with a pipeline magnetic separator provided by the present invention with reference to the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments adopt the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0024] As Figure 1 - Figure 3As shown in the figure, an embodiment of the utility model provides a powder separator equipped with a pipeline magnetic separator, including: a powder separator 1, whose bottom is connected to a return box 2 through a return pipe 4. A vacuum pump is provided inside the powder separator 1 to suck the return pipe 4, creating a low-pressure environment inside it, so as to pump the raw materials inside the return box 2 into the powder separator 1. The return pipe 4 extends into the return box 2 to a region near the bottom for easy feeding. And a stirring rod for stirring the materials is provided inside the return box 2, so that the return pipe 4 can evenly suck the raw materials inside the return box 2. The return pipe 4 is a Z-shaped pipeline. Further, the return pipe 4 can be directly connected to the discharge port of another powder separator, reducing the transfer steps of the return box 2, improving the working efficiency, and reducing the equipment assembly cost; a magnetic separator 5, installed at the top of the horizontal section of the return pipe 4, and the setting direction is parallel to the horizontal section of the return pipe 4. One end of the magnetic separator 5 protrudes from the vertical projection area of the return pipe 4. The magnetic separator 5 and the return pipe 4 are internally connected at the connection position. A conveyor belt 9 is provided inside the magnetic separator 5 and is set to run cyclically during the feeding process of the return pipe 4. The running route of the conveyor belt 9 passes through the connected area of the magnetic separator 5 and the return pipe 4; a collecting pipe 6, vertically connected to the lower part of the end of the magnetic separator 5 protruding from the return pipe 4, and the bottom end is connected to a collecting box 3; a fixing seat 10, fixed on the inner side wall of the collecting pipe 6 near the top. A scraper 11 is provided on the fixing seat 10. The top of the scraper 11 is slidably connected to the bottom surface of the end of the conveyor belt 9 close to the collecting pipe 6, and the contact surface of the scraper 11 with the conveyor belt 9 straddles both ends of the conveyor belt 9. It can be understood that the scraper 11 is in contact with the entire width of the conveyor belt 9, used to clean or scrape the residues on the belt, avoid the residual iron filings in the edge area of the belt, and re-introduce the iron filings into the return pipe 4 during continuous operation, affecting the iron removal quality.

[0025] By setting a magnetic separator 5 on the return pipe 4 of the powder separator 1, it is used to adsorb and transfer the iron filings and impurities in the raw materials transported into the powder separator 1, avoiding excessive iron filings from entering the powder separator 1, causing serious wear to the grinding media and liners inside the powder separator 1, extending the service life of the internal accessories of the powder separator 1. At the same time, the purity of the raw materials is improved, thereby improving the working efficiency of the powder separator 1, reducing the cost of production equipment accessories, and the economic benefits are obvious.

[0026] As Figure 2 shown, it further includes guide rollers 8, located inside the magnetic separator 5. There are multiple guide rollers 8, and they are rotatably connected to the two side walls of the magnetic separator 5 in parallel distribution, used to support and drive the conveyor belt 9.

[0027] By supporting the conveyor belt 9 with multiple guide rollers 8, the conveyor belt 9 is always in a flat state during operation, without scraping against the side wall of the magnetic separator 5, ensuring its smooth running.

[0028] As Figure 1As shown, it further includes a driving motor 7, which is fixedly connected to the outer side wall of the magnetic separator 5, and the output end of the driving motor 7 passes through the side wall of the magnetic separator 5 and is connected to one of the guide rollers 8.

[0029] As Figure 3 shown, a metal sheet layer 13 is embedded on the side of the conveyor belt 9 away from the guide roller 8, and a number of magnetic blocks 14 distributed in a rectangular array are provided on the side of the metal sheet layer 13 close to the inner layer of the conveyor belt 9.

[0030] By providing the magnetic blocks 14 in contact with the metal sheet layer 13, the metal sheet layer 13 is magnetized, so that the entire conveyor belt 9 has magnetism, improving the magnetic attraction effect on the iron in the material. Among them, the magnetic blocks 14 are in small particles, which can adapt to the bending of the conveyor belt 9 during operation.

[0031] As Figure 3 shown, a wear-resistant layer 12 is provided on the side of the conveyor belt 9 close to the metal sheet layer 13, and the wear-resistant layer 12 completely covers the metal sheet layer 13.

[0032] Through this setting, it is avoided that the iron filings directly contact the metal sheet layer 13 and cause wear to it.

[0033] The metal sheet layer 13 is made of permalloy material. Further, other soft magnetic composite materials can also be used. The purpose is to conduct magnetism while also having a certain degree of flexibility to adapt to the bending of the conveyor belt 9 during operation.

[0034] The return pipe 4, the collection pipe 6, the scraper 11, and the shell of the magnetic separator 5 are all made of stainless steel material. Further, other hard metal materials such as aluminum alloy or brass can also be used. The purpose is that they will not be magnetized by the magnetic blocks 14 inside the conveyor belt 9 during use, so as to adsorb the iron in the conveyed material and cause pipeline blockage.

[0035] The wear-resistant layer 12 is made of PA (polyamide) material. Further, materials such as PU (polyurethane) or special rubber can also be used. The purpose is to have high wear resistance to iron filings while also having a certain degree of flexibility to adapt to the bending of the conveyor belt 9 during operation.

[0036] In actual use, for the technical solution provided by the present utility model, through the suction of the vacuum pump inside the classifier 1, the powder materials at the discharge port of the return material box 2 or another classifier are conveyed to the classifier 1 in a dispersed form inside the return material pipe 4. Meanwhile, the driving motor 7 drives one of the guide rollers 8 to rotate, and under the action of friction, the guide roller 8 drives the conveyor belt 9 to run. When the powder materials inside the return material pipe 4 are conveyed to the connected area between the return material pipe 4 and the magnetic separator 5, due to the magnetism of the conveyor belt 9, the iron in the powder materials is adsorbed. The powder materials after iron removal are conveyed to the classifier 1. The iron adsorbed by the conveyor belt 9 moves towards one end close to the collection pipe 6 as the conveyor belt 9 runs. When it is transported to the position of the scraper 11, under the action of the scraper 11, the iron separates from the conveyor belt 9 and, under the action of gravity, falls into the interior of the collection box 3 through the guidance of the collection pipe 6. It should be specifically noted that the scraper 11 has a curved structure. When the iron filings are scraped off the conveyor belt 9 by the scraper 11, due to the magnetic force, they will still move forward along with the conveyor belt 9. Under the guiding action of the scraper 11 with an arc-shaped structure, they gradually move away from the conveyor belt 9 and out of the magnetic adsorption range, avoiding the large accumulation of iron at the contact position between the scraper 11 and the conveyor belt 9.

[0037] The present utility model covers any alternatives, modifications, equivalent methods, and solutions made within the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details have been described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model even without the description of these details. Additionally, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0038] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
