[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The iron oxide yellow pigment production device is provided with a grinding structure. During the grinding process of iron oxide particles, the iron oxide particles rotate between the grinding disc and the grinding plate, so that the iron oxide particles themselves move in the direction away from the center of the grinding plate, thereby allowing larger iron oxide particles to enter the gap between the grinding plate and the grinding tank through the side of the grinding plate, and the larger iron oxide particles will enter the inside of the aggregate special-shaped pipe through the gap. The aggregate special-shaped pipe collects and transports the larger particles to the inside of the aggregate hopper. The larger iron oxide particles enter the lower end of the recovery pipe along the bottom of the aggregate hopper, and are transported to the output end of the recovery pipe by the spiral rod inside the recovery pipe. The larger iron oxide particles are sent to the inside of the feeding pipe through the output end of the recovery pipe for re-grinding, so that the iron oxide particles are more uniform.

[0019] Furthermore, a removal structure is provided. When the magnetic particles follow the adsorption belt to move to the top of the discharge trough, the magnetic particles will be out of the range of the electromagnet, and the magnetic particles will be separated from the adsorption belt and fall into the inner side of the discharge trough. The magnetic particles are discharged to the outside of the device through the discharge trough. Since the iron oxide itself cannot be adsorbed by the magnet, the adsorbable substances inside the iron oxide particles are separated from the iron oxide particles by the electromagnet, thereby improving the purity of the iron oxide particles.

[0020] Furthermore, a cleaning structure is provided. When the iron oxide particles are cleaned, the iron oxide particle mixture is allowed to stand to allow the iron oxide particles to settle at the bottom of the cleaning tank. At this time, the water pump is started to extract the liquid inside the cleaning tank through the pumping pipe. When the liquid level inside the cleaning tank changes, the telescopic tube slides inside the extension tube, and the telescopic tube floats on the top of the liquid surface through the floating block at its lower end. Therefore, when the pumping pipe extracts the liquid inside the cleaning tank, the lower end of the telescopic tube is always kept flush with the liquid surface, thereby maintaining the efficiency of extracting the liquid from the cleaning tank.

[0021] Furthermore, a mixing structure is provided. During the mixing process of the iron oxide particles and the additives, the rotation direction of the stirring spiral plate will prevent the mixture from flowing through the stirring spiral plate. When the iron oxide particles and the additives are mixed to form yellow pigment, the rotation direction of the stirring spiral plate is changed. The rotation of the stirring spiral plate promotes the flow of the yellow pigment in the mixing tank to prevent the viscosity of the mixture from becoming high and becoming difficult to discharge. At the same time, when the iron oxide particles are in a precipitated state or are being cleaned, the reverse rotation of the transport screw rod prevents the iron oxide particles from flowing out of the discharge port. After the iron oxide particles and the additives form yellow pigment, the yellow pigment will flow to the bottom of the mixing tank and enter the discharge pipe. The rotation of the screw rod is controlled to drive the yellow pigment out of the discharge pipe to the outside of the discharge device. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Embodiment 2:

[0049] Based on the first embodiment, the specific working principle is as follows:

[0050] The device for producing yellow iron oxide pigment first adds iron oxide particles into a feeding hopper 9, so that the iron oxide particles enter into a feeding pipe 6 along the feeding hopper 9, and the feeding pipe 6 is configured as an arc structure facing a feeding trough 8. The iron oxide particles enter into the feeding trough 8 along the feeding pipe 6, and the iron oxide particles entering into the feeding trough 8 will move between a grinding plate 12 and a grinding disc 7. As the iron oxide particles in the feeding trough 8 accumulate, the mutual squeezing between the iron oxide particles will push the iron oxide particles toward the side of the feeding trough 8 until the iron oxide particles move between the grinding disc 7 and the grinding plate 12. When the grinding disc 7 rotates in the grinding tank 5, the grinding disc 7 will rotate on the top of the grinding plate 12 at the same time, thereby grinding the iron oxide particles between the grinding disc 7 and the grinding plate 12. The ground iron oxide particles will be sieved by the grinding plate 12 and fall to the top of the conveying belt 14.

[0051] During the grinding process of the iron oxide particles, the iron oxide particles rotate between the grinding disc 7 and the grinding plate 12, so that the iron oxide particles themselves move in the direction away from the center of the grinding plate 12, and then the larger particles of iron oxide pass through the side of the grinding plate 12 into the gap between the grinding plate 12 and the grinding tank 5, and the larger iron oxide particles will pass through the gap into the aggregate special-shaped tube 501, and the aggregate special-shaped tube 501 collects and transports the larger particles to the inside of the aggregate hopper 502, and the larger iron oxide particles enter the lower end of the recovery tube 10 along the bottom of the collection hopper 502, and are transported to the output end of the recovery tube 10 by the spiral rod inside the recovery tube 10, and are sent to the inside of the feeding tube 6 through the output end of the recovery tube 10 for re-grinding, so that the iron oxide particles are more uniform;

[0052] The ground iron oxide particles will fall to the top of the conveying belt 14. At this time, the conveying belt 14 and the adsorption belt 15 are driven to rotate by the roller 13, and the electromagnet 16 is energized. When the iron oxide particles pass through the bottom of the adsorption belt 15, the electromagnet 16 will adsorb the magnetic particles inside the iron oxide particles, so that the magnetic particles are separated from the iron oxide particles, and the magnetic particles move outside the adsorption belt 15. When the magnetic particles follow the adsorption belt 15 to move to the top of the discharge trough 17, the magnetic particles will be out of the range of the electromagnet 16, and the magnetic particles will be separated from the adsorption belt 15 and fall to the inside of the discharge trough 17. The magnetic particles are discharged to the outside of the device through the discharge trough 17. Since iron oxide itself cannot be adsorbed by a magnet, the adsorbable substances inside the iron oxide particles are separated from the iron oxide particles by the electromagnet 16, thereby improving the purity of the iron oxide particles.

[0053] The purified iron oxide particles will be transported to the inside of the feed hopper 19 by the transport belt 14. After passing through the feed hopper 19, the iron oxide particles enter the inside of the cleaning tank 18. Detergent and water are added to the inside of the cleaning tank 18 through the adding pipe 35 connected to the cleaning tank 18. The detergent and water are fully mixed with the iron oxide particles by the rotation of the stirring rod 20 in the cleaning tank 18 to clean the iron oxide particles.

[0054] When the iron oxide particles are cleaned, the iron oxide particle mixture is allowed to stand to allow the iron oxide particles to settle at the bottom of the cleaning tank 18. At this time, the water pump 23 is started to extract the liquid inside the cleaning tank 18 through the pumping pipe 22. When the liquid level inside the cleaning tank 18 changes, the telescopic tube 25 slides inside the extension tube 24, and the telescopic tube 25 floats on the top of the liquid surface through the floating block 26 at its lower end. Therefore, when the pumping pipe 22 extracts the liquid inside the cleaning tank 18, the lower end of the telescopic tube 25 is always kept flush with the liquid surface, thereby maintaining the efficiency of extracting the liquid from the cleaning tank 18.

[0055] The precipitated iron oxide particles enter the inside of the feeding pipe 28 through the discharge port 21 at the bottom of the cleaning tank 18, and the iron oxide particles are transported to the inside of the mixing tank 27 by the rotation of the transport screw rod 29 in the feeding pipe 28. At the same time, when the iron oxide particles are in a precipitated state or in the cleaning process, the reverse rotation of the transport screw rod 29 prevents the iron oxide particles from flowing out of the inside of the discharge port 21. At the same time, the amount of iron oxide particles entering the inside of the mixing tank 27 is controlled by controlling the rotation speed of the transport screw rod 29. Additives are added to the inside of the mixing tank 27 through the adding pipe 35 interconnected with the mixing tank 27. At the same time, the driving rod 32 drives the inertia rod 33 to rotate in the mixing tank 27 to stir the iron oxide particles and the additives, so that the iron oxide particles form yellow pigment;

[0056] During the mixing process of the iron oxide particles and the additives, the rotation direction of the stirring spiral plate 34 will prevent the mixture from flowing through the stirring spiral plate 34. When the iron oxide particles and the additives are mixed to form yellow pigment, the rotation direction of the stirring spiral plate 34 is changed. The rotation of the stirring spiral plate 34 promotes the flow of the yellow pigment in the mixing tank 27 to prevent the viscosity of the mixture from becoming high and becoming difficult to discharge. At the same time, when the iron oxide particles are in a precipitation state or are being cleaned, the reverse rotation of the transport screw rod 29 prevents the iron oxide particles from flowing out of the discharge port 21. After the iron oxide particles and the additives form yellow pigment, the yellow pigment will flow to the bottom of the mixing tank 27 and enter the discharge pipe 30. The rotation of the screw rod 31 is controlled to drive the yellow pigment out of the discharge pipe 30 to discharge the device outside.
