Description

Technical Field

[0001] The utility model relates to the technical field of iron removal equipment, in particular to a calcium carbonate powder double-layer iron removal equipment. Background Art

[0002] Calcium carbonate powder is an important inorganic compound. It is neutral and essentially insoluble in water, but soluble in hydrochloric acid. Calcium carbonate is widely found on Earth and is also the main component of animal bones or shells. Iron impurities in calcium carbonate powder can affect its product quality and application performance, so it requires iron removal. When selecting a method for removing iron from calcium carbonate powder, the following factors should be considered: the content and form of iron impurities, the application and quality requirements of the calcium carbonate powder, cost, and environmental requirements. At the same time, experimental research is also needed to determine the optimal iron removal process parameters to ensure iron removal results and product quality.

[0003] The utility model application number 202221446243.4 discloses an iron removal device for preparing high-purity quartz sand. The device continuously adds high-purity quartz sand raw materials into the inside of the funnel, and simultaneously connects the power supply to the arc-shaped electromagnet on the inside of the conical shell. The conical shell is made of iron material, so the conical shell has magnetism. When the quartz sand raw materials fall on the conical shell under the action of gravity, they are guided by the conical shell. At the same time, the iron in the quartz sand will be adsorbed on the conical shell under the action of magnetic force, and the stone The quartz sand is separated, the structure is simple, and the quartz sand can be continuously deironed, thereby improving the efficiency of quartz sand deironing. After the electric push rod is powered on, the movable end of the electric push rod is used to drive the cover shell to move upward, so that the inner bottom end of the cover shell abuts against the edge of the lower surface of the bottom plate, so that the top end of the cover shell protrudes from the upper surface of the bottom plate. When the arc-shaped electromagnet is powered off, the iron material adsorbed on the outer wall of the conical shell will be gathered on the inner side of the cover shell under the action of gravity, thereby facilitating the collection and treatment of the iron material.

[0004] However, when the above-mentioned high-purity quartz sand preparation iron removal equipment is used for iron removal, the quartz sand falls from the funnel and then falls along the conical shell. The quartz sand falls at a fast speed, which may make the conical shell insufficient in adsorbing the iron in the quartz sand. It is necessary to manually pour the quartz sand into the funnel again, resulting in low iron removal efficiency. When the above-mentioned high-purity quartz sand preparation iron removal equipment is used for iron removal, the quartz sand easily slides out along the bottom plate and scatters around after sliding down the conical shell, making it difficult to collect the quartz sand after iron removal. Therefore, the utility model proposes a double-layer calcium carbonate powder iron removal equipment to solve the problems existing in the prior art. Utility Model Content

[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0018] according to Figure 1 、 Figure 2 、 Figure 3As shown, this embodiment provides a double-layer iron removal equipment for calcium carbonate powder, including a bracket 1, a magnetic separation mechanism, a rotating mechanism and a turning mechanism. The magnetic separation mechanism includes a magnetic separation rolling bin 2, an electromagnet 3, a conductive brush 4, a conductive block 5, a connecting pipe 6 and a wire 7. A magnetic separation rolling bin 2 is rotatably provided between the brackets 1. An electromagnet 3 is fixedly provided around the inner wall of the magnetic separation rolling bin 2. A conductive brush 4 is fixedly provided in the middle of the electromagnet 3. A conductive block 5 is provided on the inner side of the conductive brush 4. A connecting pipe 6 is fixed on the other side of the conductive block 5. A wire 7 is provided in the connecting pipe 6. The connecting pipe 6 extends through the other side of the magnetic separation rolling bin 2. A rotating mechanism is provided on one side of the magnetic separation rolling bin 2, and a turning mechanism is provided on the outside of the magnetic separation rolling bin 2. The inner side of the conductive brush 4 is in contact with the conductive block 5 for conductivity, and the wire 7 is electrically connected to the wire 7. When magnetic separation and iron removal are performed, current is passed through the wire 7 and then transmitted to the conductive block 5 and the conductive brush 4, so that the electromagnet 3 is energized to generate magnetism. The magnetic separation rolling bin 2 is made of metal and will generate magnetism at the same time as the electromagnet 3. After the calcium carbonate powder is poured into the barrel 11, the magnetic separation rolling bin 2 magnetically absorbs the iron in the calcium carbonate powder. After the wire 7 is powered off, the magnetism of the electromagnet 3 disappears, which is convenient for collecting the screened iron. The magnetic separation and iron removal time can be adjusted as needed, which solves the problem that the calcium carbonate powder slides down quickly, causing the conical shell to insufficiently absorb the iron in the calcium carbonate powder, and multiple adsorption and iron removal operations are required.

[0019] The rotating mechanism includes a rotating shaft 8, a bearing seat 9 and a first motor 10. The rotating shaft 8 is fixed in the middle of one side of the magnetic separation rolling bin 2, and a bearing seat 9 is fixed on the inner side of the bracket 1. The rotating shaft 8 passes through the bearing seat 9. A first motor 10 is fixed on one side of the bracket 1. The output end of the first motor 10 is connected to the rotating shaft 8. When magnetic separation and iron removal are performed, the first motor 10 starts to drive the rotating shaft 8 to rotate, and the rotating shaft 8 drives the magnetic separation rolling bin 2 to rotate, so that the magnetic separation rolling bin 2 is fully in contact with the calcium carbonate powder, thereby improving the adsorption and iron removal efficiency.

[0020] The turning mechanism includes a barrel 11, a guide rail 12, a fixed plate 13, a roller 14 and a second motor 15. The outer cover of the magnetic separation rolling bin 2 is provided with a barrel 11. Guide rails 12 are fixed around the outer sides of the barrel 11. A fixed plate 13 is fixed below the bracket 1. Rollers 14 are symmetrically rotated on the fixed plate 13. A second motor 15 is fixed on one side of the fixed plate 13. The output end of the second motor 15 is driven and connected to the roller 14. The position of the roller 14 corresponds to the guide rail 12. The second motor 15 drives the roller 14 to rotate with the guide rail 12 to drive the barrel 11 to rotate and turn the material. A through hole 16 is opened in the middle of the fixed plate 13. A feed pipe 17 is connected in the middle of the barrel 11. A solenoid valve 18 is fixed on the feed pipe 17. The feed pipe 17 corresponds to the position of the through hole 16. When the feed pipe 17 is turned, the feed pipe 17 is connected to the feed pipe 17. Before magnetic separation and iron removal, the second motor 15 starts to drive the roller 14 to rotate, and the friction between the roller 14 and the guide rail 12 drives the barrel 11 to rotate until the inlet and outlet pipes 17 face upward, then the solenoid valve 18 is opened, and the calcium carbonate powder is poured into the barrel 11 from the inlet and outlet pipes 17. After the solenoid valve 18 is closed, the second motor 15 is restarted to rotate the barrel 11 for iron removal. After the iron removal is completed, the barrel 11 is rotated until the inlet and outlet pipes 17 face downward, and the solenoid valve 18 is opened, so that the calcium carbonate powder after iron removal is discharged from the inlet and outlet pipes 17. After that, the wire 7 stops supplying power to the electromagnet 3, the magnetism of the electromagnet 3 disappears, and the adsorbed iron falls off and is discharged from the inlet and outlet pipes 17, so that the calcium carbonate powder and the iron are discharged from the same position, which solves the problem that the calcium carbonate powder is easily scattered around after sliding down the conical shell, making it difficult to collect the calcium carbonate powder after iron removal.

[0021] When the calcium carbonate powder double-layer iron removal equipment is performing iron removal processing, the second motor starts to drive the roller to rotate, and the friction between the roller and the guide rail drives the barrel to rotate so that the inlet and outlet pipes face upward, the solenoid valve is opened to pour the calcium carbonate powder from the inlet and outlet pipes into the barrel, and then the solenoid valve is closed. The second motor restarts to drive the barrel to rotate so that the calcium carbonate powder is flipped in the barrel. When the wire is energized, the current is transmitted to the electromagnet through the conductive block and the conductive brush. The electromagnet is energized to generate magnetism. At the same time, the first motor starts to drive the rotating shaft to rotate, driving the magnetic separation rolling bin and the barrel to rotate in the opposite direction, fully contacting the calcium carbonate powder so that the iron in the calcium carbonate powder is adsorbed on the magnetic separation rolling bin. After the iron removal is completed, when the inlet and outlet pipes rotate downward with the barrel, the second motor stops, and the solenoid valve opens to discharge the calcium carbonate powder after iron removal from the inlet and outlet pipes. After the calcium carbonate powder is discharged, the wire is de-energized, the electromagnet is turned off, and the electromagnetic property is eliminated. The iron adsorbed on the magnetic separation rolling bin falls and is discharged from the inlet and outlet pipes to achieve iron removal of the calcium carbonate powder.
