[0002] Refractory bricks, also known as fire bricks, are building materials with specific shapes made of refractory clay or other refractory raw materials through high-temperature firing. During the manufacturing process of refractory bricks, the purity of the raw materials directly affects the quality and performance of the final products. If iron and other magnetic impurities in the raw materials are not effectively removed, it will seriously affect the quality and performance of refractory bricks. However, when the existing equipment removes magnetic impurities, due to reasons such as too fast feeding or other reasons, the raw materials often accumulate, resulting in the inability of the raw materials in many positions to come into contact with the magnet during magnetic attraction, and ultimately failing to achieve a good effect of removing magnetic impurities.

[0027] To avoid demagnetization of the equipment due to high temperature. In this embodiment, referring to Figure 4 , rotating rods 18 are coaxially and fixedly arranged on both the first magnetic roller 4 and the second magnetic roller 6. A cooling cavity 19 is formed between the rotating rod 18 and the permanent magnet 14. An air vent hole 20 that is coaxial and penetrates the end of the rotating rod 18 is formed inside the rotating rod 18. A plurality of air exchange holes 21 that communicate the cooling cavity 19 with the air vent hole 20 are formed on the rotating rod 18.

[0028] Usage method of the raw material magnetic separator for refractory brick production of the present utility model: First, control the operation of the motor 25, so as to drive the rotation of the first magnetic roller 4 and the second magnetic roller 6 through the belt 26 and the pulley 24. Then pour the raw materials into the interior of the equipment shell 1 from the feed port 2, and they fall on the oscillating plate 3 and are simply blocked by the baffle 11. At this time, control the operation of the vibrator 8, so that the oscillating plate 3 vibrates under the action of the spring 10, evenly spreads the raw materials and fully spreads them through the baffle 11 and the through groove 12. During this process, the oscillating plate 3 drives the driven plate 5 to vibrate synchronously through the connecting rod 13. Then, after the raw materials are spread on the oscillating plate 3 and the through groove 12, they fall on the rotating first magnetic roller 4, are magnetically adsorbed by the first magnetic roller 4 and then fall on the driven plate 5, and then fall on the second magnetic roller 6 for secondary magnetic adsorption. Thus, the raw materials are made to contact the first magnetic roller 4 and the second magnetic roller 6 as much as possible to ensure the magnetic adsorption effect.

[0029] During this process, the magnetic impurities adsorbed on the first magnetic roller 4 and the second magnetic roller 6 are scraped off by the scraper 15 to ensure that the first magnetic roller 4 and the second magnetic roller 6 are in a clean state when contacting the raw materials. The scraped magnetic impurities enter the interior of the collection box 17 through the guide plate 16, which is convenient for subsequent treatment. The raw materials after magnetic adsorption are discharged through the discharge port 7. During this process, the internal situation of the equipment rack can be observed in real time through the observation window 23, which is convenient for subsequent inspection and maintenance.

[0030] When the temperature of the permanent magnet 14 is relatively high due to long-term operation, the air supply hole 20 of the rotating rod 18 can be externally connected to an air supply device to provide air inside the air supply hole 20. At this time, the air enters the cooling cavity 19 through the air exchange hole 21 to cool the permanent magnet 14, preventing it from demagnetizing due to high temperature and affecting the magnetic impurity adsorption effect inside the raw materials. At this time, the air entering the cooling cavity 19 carries high temperature and is discharged through the exhaust hole 22.
