[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To address the issue of existing magnetic screening devices for foundry waste sand exhibiting poor screening performance during practical use, necessitating secondary sorting and disrupting continuous operation, please refer to [the relevant documentation / reference]. Figure 1 - Figure 4 This embodiment provides the following technical solution:

[0023] This embodiment of a magnetic screening device for foundry waste sand includes a welding frame 1, a feeding frame 2 installed inside the welding frame 1, a magnetic source box 201 installed inside the feeding frame 2, a magnetizing surface at the upper end of the magnetic source box 201, and a demagnetizing surface at the lower end of the magnetic source box 201. A conveyor belt 3 is installed outside the magnetic source box 201, and a distribution box 4 is installed below the conveyor belt 3. A rotating shaft 5 is installed at the upper end of the distribution box 4, and a scraper 503 is installed in the middle of the rotating shaft 5. The position of the scraper 503 corresponds to the position of the demagnetizing surface. By its own weight, non-ferrous materials fall into the receiving trolley 404, while magnetized iron moves to the bottom of the magnetic source box 201 and is demagnetized by the demagnetizing surface, so it can be scraped down into the screening frame 401 by the scraper 503. This allows for continuous operation, has a simple structure, improves screening effect, and facilitates subsequent work.

[0024] A sling 202 is installed between the welding frame 1 and the feeding frame 2, and the sling 202 is fixedly connected to the welding frame 1 and the feeding frame 2 respectively.

[0025] Both ends of the conveyor belt 3 are equipped with conveyor rollers 303. The conveyor rollers 303 are rotatably connected to the feeding frame 2 through bearings. The foundry waste sand that needs to be magnetically screened is moved on the feeding frame 2 by the conveyor belt 3. After being moved to the magnetic source box 201, the iron in the foundry waste sand is magnetized by the magnetizing surface on the magnetic source box 201.

[0026] In fact, a support frame 302 is welded to the upper end of the feeding rack 2, and a servo motor 301 is fixedly connected to the upper end of the support frame 302. The servo motor 301 is connected to the transmission roller 303 through a transmission belt. The transmission roller 303 is engaged with the transmission belt 3. During the movement, the iron is attracted into the feeding rack 2. After being attracted and moved to one end of the transmission belt 3, the non-ferrous material falls into the receiving trolley 404 by its own weight. The magnetized iron moves to the bottom of the magnetic source box 201 and is demagnetized by the demagnetizing surface.

[0027] Specifically, the foundry waste sand requiring magnetic screening is moved on the feeding rack 2 via the conveyor belt 3 to the magnetic source box 201. The magnetizing surface on the magnetic source box 201 magnetizes the iron in the foundry waste sand, causing the iron to be attracted into the feeding rack 2 during the movement. After being attracted and moved to one end of the conveyor belt 3, the non-ferrous material falls into the receiving trolley 404 by its own weight. The magnetized iron moves to the bottom of the magnetic source box 201 and is demagnetized by the demagnetizing surface. It can then be scraped off by the scraper plate 503 into the screening rack 401. This allows for continuous operation, has a simple structure, improves the screening effect, and facilitates subsequent work.

[0028] To address the issue that existing magnetic screening devices for foundry waste sand suffer from a simple structure and inconvenience in subsequent processing during practical use, please refer to... Figure 1 - Figure 4 This embodiment provides the following technical solution:

[0029] In this embodiment, a screening rack 401 is slidably connected inside the material distribution box 4. An inclined filter screen 402 is provided inside the screening rack 401, and a dust outlet 403 is provided below the filter screen 402. The material distribution box 4 adopts a structure combining a material receiving trolley 404 and a screening rack 401, which can perform sorting work. The inclined filter screen 402 inside the screening rack 401 can perform secondary filtration on the screened iron, and discharge the dust on the surface of the iron to the dust outlet 403, which is beneficial to improving the magnetic screening effect.

[0030] The material distribution box 4 is equipped with a material receiving trolley 404 on one side. Both the material receiving trolley 404 and the screening rack 401 are equipped with rollers at their lower ends. The material receiving trolley 404 is used to collect scrap iron materials for recycling. The material receiving trolley 404 is easy to move and facilitates continuous operation.

[0031] In addition, the rotating shaft 5 is fixedly connected to the scraper 503, and both ends of the rotating shaft 5 are fixedly connected to the rotating arm 501. A stepper motor 502 is installed at one end of the rotating arm 501. The stepper motor 502 is fixedly connected to the welding frame 1. The scraper 503 is attached to the lower end of the conveyor belt 3. By adjusting the rotating shaft 5, the angle position of the scraper 503 is changed, and the scraping effect is adjusted accordingly.

[0032] Specifically, the material sorting box 4 adopts a structure combining a receiving trailer 404 and a screening rack 401, which can perform sorting work. The inclined filter screen 402 inside the screening rack 401 can perform secondary filtration on the screened iron, and discharge the dust on the surface of the iron to the dust outlet 403, which is beneficial to improve the magnetic screening effect. The receiving trailer 404 collects the scrap iron material for recycling. The receiving trailer 404 is easy to move and facilitates continuous operation.

[0033] Working principle: During use, foundry waste sand requiring magnetic screening is moved on the feeding rack 2 via the conveyor belt 3. After being moved to the magnetic source box 201, the iron in the foundry waste sand is magnetized by the magnetizing surface on the magnetic source box 201. As the iron moves, it is attracted into the feeding rack 2. After being attracted and moved to one end of the conveyor belt 3, the non-ferrous material falls into the collection trolley 404 by its own weight. The magnetized iron moves to the bottom of the magnetic source box 201 and is demagnetized by the demagnetizing surface. It can then be scraped off by the scraper 503 into the screening rack 401. By adjusting the rotating shaft 5, the scraper can be adjusted to change the magnetic material's magnetic properties. The angle of the material plate 503 is adjusted to adapt to the scraping effect. The material distribution box 4 adopts a combination of a receiving trolley 404 and a screening frame 401, which can perform sorting work. The inclined filter screen 402 inside the screening frame 401 can perform secondary filtration on the screened iron, and discharge the dust on the surface of the iron to the dust outlet 403, which is beneficial to improve the magnetic screening effect. The receiving trolley 404 collects the scrap iron material for recycling. The receiving trolley 404 is easy to move, so it can be used for continuous work. The structure is simple, improves the screening effect, and facilitates subsequent work.
