Therefore, effective iron removal of ceramic tile blanks has become one of the key issues that the industry needs to solve urgently.

[0003] Traditional technologies for removing iron from ceramic tile blanks mainly include static magnetic separation and chemical leaching. Static magnetic separation has a good removal effect on large particles and strong magnetic iron impurities, but it is not effective for fine weak magnetic or non-magnetic iron oxide impurities. Although chemical leaching can handle various forms of iron impurities, it has a long treatment cycle, high cost, and may cause environmental pollution. Summary of the invention

[0023] In a preferred solution, an electrically controlled three-way valve 12 is provided at the connection position between the pulp inlet branch pipe 11 and the first pulp outlet pipe 6 .

[0024] In a preferred solution, the upper weak magnetic plate 2 and the lower strong magnetic plate 3 are connected to a magnetic field regulating module 15 via cables, and the magnetic field regulating module 15 is used to adjust the strength and direction of the magnetic field generated by the upper weak magnetic plate 2 and the lower strong magnetic plate 3.

[0026] The invention discloses an automatic iron removal device for raw materials for ceramic tile blanks, which comprises the following steps when performing the iron removal operation for ceramic tile blanks:

[0027] 1. Raw material preparation and transportation stage:

[0028] First, the tile blank slurry to be processed is transported to the ultrasonic treatment box 4 through a feeding pump to ensure that the slurry is uniform and stable.

[0029] 2. Ultrasonic pretreatment stage: The slurry first enters the ultrasonic treatment box 4, and the ultrasonic transducer 9 is used to generate high-intensity ultrasonic waves, which act on the slurry. The cavitation effect of the ultrasonic waves is used to fully disperse the agglomerated iron impurity particles, while promoting uniform mixing inside the slurry and improving the effect of subsequent magnetic separation.

[0030] 3. Microwave-induced reduction stage: The slurry after ultrasonic treatment is then transported to the microwave induction box 10, and the microwave generator 14 emits microwaves of a specific frequency to selectively heat the slurry, especially the area containing iron oxide components, so that it is quickly reduced to metallic iron with stronger magnetism.

[0031] 4. Double-layer dynamic magnetic separation stage: The slurry after microwave reduction is introduced into the iron removal box 1, and the upper layer is treated with the upper weak magnetic plate 1, which is mainly used for the small-particle magnetic material after reduction, and the lower layer is equipped with the lower strong magnetic plate 3, which is mainly used to adsorb larger particles of iron impurities.

[0032] At the same time, the magnetic field strength and direction of the magnetic separation zone can be adjusted in real time through the magnetic field adjustment module 15 according to the iron impurity content and characteristics in the slurry to achieve the best magnetic separation effect.

[0033] 5. Circulation optimization treatment: The slurry after the first magnetic separation may still contain a small amount of iron impurities that have not been completely separated. Therefore, it returns to the ultrasonic treatment box 4 through the return slurry pipe 7 and the return slurry pump 8 for secondary dispersion treatment, and then passes through the iron removal box 1, and repeats this cycle until the set iron removal standard is reached.

[0034] 6. Finished product inspection and output: After completing the above steps, the slurry is output through the third slurry output pipe 16. The output slurry is checked by the detection equipment to see if the iron content meets the standard. The clean slurry that meets the standard can be transported to the next tile forming process.
