Description

Technical Field

[0001] The utility model relates to the technical field of mixing and grinding, in particular to a mixing and grinding device for phosphorus pig iron carburizing and stabilizing agent. Background Art

[0002] Phosphorus pig iron is a process flow in the anode assembly process. The casting process is the most critical process in the assembly, which is directly related to the quality of the anode assembly, and further affects key indicators such as the change in the current efficiency of the electrolytic cell and the stability of the entire series of iron-carbon pressure drops. Therefore, the composition, formula and usage of phosphorus pig iron are one of the most critical technical links to ensure the quality of anode assembly. In order to increase the number of times phosphorus pig iron is used, a recarburizing stabilizer is usually added during use to maintain the properties of phosphorus pig iron and prevent the carbon content in phosphorus pig iron from decreasing and degenerating due to long-term use.

[0003] The utility model patent with the authorization announcement number CN217164664U discloses a metal powder grinding device, which includes a grinding tank, the upper surface of which is fixedly connected to a feed hopper, the lower surface of which is fixedly connected to a discharge pipe, the outer surface of which is fixedly installed with a solenoid valve, the inner wall of which is fixedly sleeved with a conical screen, and the lower inner wall of which is fixedly sleeved with a mounting plate. The metal powder grinding device is provided with a circulation grinding device on the upper surface of the mounting plate, and the circulation grinding device includes a circulation pipe, the lower surface of which is fixedly connected to the upper surface of the mounting plate, so as to achieve the effect of finely grinding metal particles, and automatically recovering and re-grinding metal powder particles that do not meet the standards during discharge.

[0004] Although the above utility model can automatically recycle and re-grind the metal powder particles that do not meet the standards, when using the grinding device to grind the metal into metal powder, the diameter of the metal entering the grinding device needs to be controlled, otherwise the raw material cannot enter the grinding mechanism and be smoothly ground into metal powder, which is inconvenient to use. In view of this, we propose a phosphorus pig iron carburizing stabilizer mixing grinding device. Utility Model Content

Through the above mechanism, it can be ensured that all raw materials entering the grinding cylinder 1 can smoothly enter the grinding mechanism 13 and be ground.

[0028] It should be supplemented that a plurality of grinding balls are installed on the lower surface of the upper grinding plate 131 and the upper surface of the lower grinding plate 134 .

[0029] Furthermore, the grinding mechanism 13 includes a plurality of support rods 135 welded to the inner surface of the grinding cylinder 1 and a lower grinding plate 134 welded to the upper side of the support rods 135, a recovery hole 136 is provided in the middle position of the upper surface of the lower grinding plate 134, an upper grinding plate 131 is provided on the upper side of the lower grinding plate 134, a feed hole 132 is provided on the upper surface of the upper grinding plate 131, a plurality of connecting rods 133 are welded in the feed hole 132, and by welding the connecting rods 133 to the rotating shaft in the recovery and filtering mechanism 15, the upper grinding plate 131 can rotate synchronously when the rotating shaft rotates.

[0030] Furthermore, a control motor 21 is fixedly installed in the middle position of the upper surface of the upper cover 2, a feed port 22 is opened on one side of the upper surface of the upper cover 2, and a feed pipe 23 is arranged at the upper end of the feed port 22 to guide all the raw materials into the grinding mechanism 13.

[0031] In this embodiment, there is a gap between the grinding mechanism 13 and the inner surface of the grinding cylinder 1 , and a filter screen 14 is installed in the gap. The aperture of the filter screen is much larger than the aperture of the filter screen in the recovery filter mechanism 15 .

[0032] In this embodiment, the upper surface of the filter screen 14 is located on the lower side of the lower surface of the lower grinding plate 134, and the recovery hole 136 is close to the upper end of the circulation pipe in the recovery filter mechanism 15, ensuring that the raw materials recovered by the circulation pipe of the recovery filter mechanism 15 can smoothly re-enter the grinding mechanism 13.

[0033] In this embodiment, the connecting rod 133 is welded to the upper side of the rotating shaft in the recovery and filtering mechanism 15, and one end of the support rod 135 is welded to the outer surface of the circulation pipe in the recovery and filtering mechanism 15 to ensure that the rotating shaft can drive the upper grinding plate 131 to rotate.

[0034] In this embodiment, the upper end of the guide groove 11 is located at the lower end of the feed port 22 , and the guide channel 12 is located just above the feed hole 132 , which can smoothly guide the raw materials entering from the feed port 22 into the grinding mechanism 13 .

[0035] In this embodiment, the cross-section of the upper grinding plate 131 is an isosceles trapezoidal structure that is narrow at the top and wide at the bottom, and the cross-section of the lower grinding plate 134 is an isosceles trapezoidal structure that is narrow at the top and wide at the bottom.

The rotating shaft drives the upper grinding plate 131 to rotate through the connecting rod 133, and then the raw materials are fed into the grinding cylinder 1 from the feeding pipe 23 on the upper side of the feeding port 22. Then, the raw materials smoothly enter the grinding mechanism 13 from the feeding hole 132 under the guidance of the guide groove 11 and the guide channel 12. After being ground by the grinding mechanism 13, they pass through the filter screen 14 and enter the filter screen at the lower end of the recovery and filtering mechanism 15. Those with qualified sizes pass through the filter screen for output, and those with unqualified sizes pass through the circulation pipe of the recovery and filtering mechanism 15 and re-enter the grinding mechanism 13 to be ground.
