Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of magnetic separators, for example to an iron removal tool for coated sand regeneration. BACKGROUND

[0002] The description in this section merely provides background information relating to the present disclosure and does not constitute prior art.

[0003] Coated sand molds are widely used in the casting process, as they have good formability and high-temperature stability, and can meet the production needs of complex castings. After being used in casting, coated sand needs to be recycled for reuse. During the regeneration process, metal impurities (such as iron filings) in the sand mold inevitably mix into the coated sand, which can seriously affect the quality of the recycled sand and thus adversely affect the performance of subsequent cast products. Therefore, during the regeneration process, iron removal treatment is a crucial step. Currently, existing iron removal tools usually occupy a large space, making it difficult to adapt to the compact layout of modern assembly production lines, limiting their application in enclosed environments. Existing tools are mostly open in design, which can easily lead to the spread of dust and metal impurities during iron removal, not only polluting the working environment, but also potentially harming the health of operators. SUMMARY

[0004] The present application provides an iron removal tool for coated sand regeneration, which integrates core components such as a material guide groove, a magnetic roller, and a scraper assembly into a compact structure through a closed box design. The height-integrated design of the box can adapt to the narrow space layout of modern assembly production lines.

[0005] An iron removal tool for coated sand regeneration, comprising:

[0006] a box, having a feed inlet at the top and a first discharge outlet at the bottom;

[0007] a material guide groove fixedly installed inside the box, with its upper end communicating with the feed inlet and a linear drop port extending along its length direction at the lower end;

[0008] a magnetic roller rotatably arranged inside the box, with its axis direction parallel to the extension direction of the drop port and satisfying the following positional relationship:

[0009] the vertical projection of the drop port completely covers the circumferential surface of the magnetic roller;

[0010] the vertical projection of the drop port on the horizontal plane of the magnetic roller axis is located on one side of the axis;

[0011] a collection groove fixedly installed inside the box, below the magnetic roller;

[0012] A scraper assembly is installed on the inner wall of the collection tank or box, and the scraping end thereof is in contact with the surface of the magnetic roller, for scraping the iron materials adsorbed on the magnetic roller to the collection tank.

[0013] A second discharge port is arranged on the side wall of the box and is in communication with the collection tank.

[0014] A power source is in driving connection with the magnetic roller to drive the rotation thereof.

[0015] In some embodiments, the number of the material guide grooves is two, and the feeding port is divided into two symmetrically distributed channels along the axial line thereof, and is in communication with the upper ends of the two material guide grooves, respectively.

[0016] The magnetic roller and the scraper assembly are arranged below each material guide groove.

[0017] In some embodiments, the end portions of the two magnetic rollers extend to the outside of the box and are in driving engagement through a gear set.

[0018] The power source is in driving connection with the end portion of one of the magnetic rollers.

[0019] In some embodiments, the scraper assembly comprises:

[0020] A fixed shaft is horizontally fixed to the inner wall of the collection tank.

[0021] A scraper is rotatably sleeved on the fixed shaft, and the scraping end thereof is in contact with the surface of the magnetic roller.

[0022] An elastic return member is connected between the scraper and the collection tank or the fixed shaft, for providing an elastic force for pressing the scraper against the magnetic roller.

[0023] In some embodiments, the elastic return member is a torsion spring, which is sleeved on the fixed shaft, one end of which is fixedly connected with the scraper, and the other end of which is fixedly connected with the side wall of the collection tank.

[0024] In some embodiments, the power source comprises:

[0025] An electric motor is in driving connection with the end portion of the magnetic roller through a belt pulley set.

[0026] An electric motor support is fixed to the outer wall of the box, for supporting the electric motor.

[0027] The iron removal tool for coated sand regeneration provided by the present application can achieve the following technical effects:

[0028] Through the design of the closed box, the core components such as the material guide groove, the magnetic roller and the scraper assembly are integrated in a compact structure, and the height integrated design of the box can adapt to the narrow space layout of the modern assembly type production line.

[0029] The design of symmetrically distributing the double guide grooves further optimizes the space utilization efficiency.

[0030] The magnetic roller axis is parallel to the extension direction of the material falling port, and the material falling port vertical projection completely covers the circumferential surface of the magnetic roller, ensuring that the metal impurities are fully adsorbed when the coated sand flows.

[0031] The scraper assembly uses elastic return elements (such as torsional springs) to press the surface of the magnetic roller, which can adapt to the slight deformation of the roller surface and ensure that the ferrous materials are stably scraped into the collection groove, and the iron removal efficiency can reach more than 95%.

[0032] The closed box design effectively suppresses dust diffusion, reduces the health hazards of dust impurities to operators, and reduces the cleaning and maintenance cost of the workshop.
