Description

Technical Field

[0001] This utility model relates to the technical field of granular magnesium oxide impurity removal equipment, and in particular to a granular magnesium oxide impurity removal device. Background Technology

[0002] Granular magnesium oxide generally refers to granulated magnesium oxide products made from magnesium oxide. Magnesium oxide powder is granulated by a swaying granulation machine. However, in the existing manufacturing process, the products often contain mechanical impurities, especially metallic impurities, which seriously affect the material safety of downstream products.

[0003] A search revealed that existing technologies for removing granular magnesium oxide mostly rely on sieving with filters, which is inefficient at removing magnetic impurities and often requires longer processing times or more steps. Furthermore, simple sieving cannot solve the surface bridging problem of granular magnesium oxide, leading to material accumulation and blockage during the removal process, further reducing efficiency. Therefore, this paper proposes a granular magnesium oxide impurity removal device to address these issues. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1.

The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figures 1 to 4In this embodiment of the present invention, a particulate magnesium oxide impurity removal device includes: an impurity removal barrel 1, a feed inlet 2 at the top of the impurity removal barrel 1, a particulate output outlet 3 on the side of the impurity removal barrel 1, an impurity output outlet 4 at the bottom of the impurity removal barrel 1, a magnetic rod insertion port 5 on the side of the impurity removal barrel 1, a side moving plate 6 on the side of the impurity removal barrel 1 near the magnetic rod insertion port 5, a magnetic rod rotating disk 7 rotatably connected to the side of the side moving plate 6 near the magnetic rod insertion port 5, multiple sets of electrically driven magnetic rods 8 fixedly connected to the side of the magnetic rod rotating disk 7, a rotating motor 10 fixedly connected to the side of the side moving plate 6, two sets of first connecting blocks 11 fixedly connected to the side of the side moving plate 6, and two sets of second connecting blocks 12 fixedly connected to the side of the impurity removal barrel 1. An electric telescopic rod 13 is fixedly connected between a connecting block 11 and a second connecting block 12. An impurity collection box 14 is provided below the impurity removal barrel 1, and a discharge port is opened above the impurity collection box 14. A collection box sealing cover 15 is rotatably connected to the impurity removal barrel 1 near the discharge port. An impurity collection port 16 is opened above the impurity collection box 14. An auxiliary lifting cylinder 17 is fixedly connected to the inside of the impurity collection port 16, and a sieve filter screen 18 is fixedly connected to the inside of the auxiliary lifting cylinder 17. A vibration motor 19 is fixedly connected to the inside of the impurity collection box 14. The feed port 2, particle output port 3, impurity output port 4, and magnetic rod insertion port 5 are all in communication with the inner cavity of the impurity removal barrel 1. After being granulated, the powdered magnesium oxide is fed into the impurity removal barrel 1 through the feed port 2. The electrically driven magnetic rod 8 rotates under the drive of the rotating motor 10, which solves the problem of material bridging, and at the same time uses electromagnetic force to adsorb magnetic impurities. When the magnetic rod adsorbs a certain amount of material or reaches a preset time, the electric telescopic rod 13 operates, pushing the side moving plate 6 and the magnetic rod rotating disk 7, causing the electrically driven magnetic rod 8 to be pushed out of the impurity removal barrel 1. At this time, by controlling the external power supply to disconnect, the electrically driven magnetic rod 8 loses its magnetic force, and the magnetic metal impurities automatically fall off. Impurities not adsorbed by the electrically driven magnetic rod 8 fall into the impurity collection port 16 under the action of gravity. After being screened by the sieve filter 18, the granular magnesium oxide is retained at the top and discharged through the granular output port 3, while the fine metal impurities pass through the sieve filter 18 and fall into the bottom of the impurity collection box 14 under the action of gravity. The vibration motor 19 operates, driving the sieve filter 18 to sieve up and down repeatedly, which can enhance the impurity removal accuracy and reduce the phenomenon of clogging of the sieve filter 18, further improving the impurity removal effect, thereby helping to improve the high purity of granular magnesium oxide.

[0022] The electrically driven magnetic rod 8 is connected to an external power source via a conductive slip ring. The design of the conductive slip ring allows the electrically driven magnetic rod 8 to maintain a continuous electrical connection with the external power source during rotation, thus ensuring stable power transmission during rotation. Furthermore, this design ensures that the electrically driven magnetic rod 8 can continuously generate magnetic force, stably adsorbing magnetic impurities in the particulate magnesium oxide, thereby maintaining continuous removal of magnetic impurities and effectively improving the impurity removal efficiency of the device.

[0023] The rotating shaft of the rotating motor 10 passes through the side moving plate 6 and is fixedly connected to the magnetic rod rotating disk 7. The rotating motor 10 directly drives the magnetic rod rotating disk 7 to rotate through its rotating shaft, thereby driving the electrically driven magnetic rod 8 to rotate. This can prevent the accumulation and blockage of materials during the impurity removal process and ensure the smooth flow of materials. By directly driving the magnetic rod rotating disk 7, the electrically driven magnetic rod 8 can be continuously rotated during the impurity removal process, which can effectively solve the problem of material bridging.

[0024] Impurity outlet 4 and impurity collection port 16 are connected by a flange, facilitating quick assembly, disassembly, and sealing between them. Furthermore, the flange connection creates a reliable sealing interface between the impurity outlet 4 and the impurity collection port 16. This structure provides a tight contact surface, effectively preventing impurity leakage or contamination from external pollutants due to poor connection, ensuring that impurities can smoothly and uncontaminatedly enter the impurity collection box 14, thus guaranteeing the cleanliness of the impurity collection process.

[0025] The bottom wall heights of the sieving screen 18 and the particle outlet 3 are matched, which prevents the screened granular magnesium oxide from becoming clogged or stuck during discharge due to height mismatch. This allows the granular magnesium oxide to flow naturally to the particle outlet 3 under gravity, ensuring that the screened granular magnesium oxide can be discharged smoothly, while preventing the mixing of fine impurities and improving the impurity removal accuracy.

[0026] The working principle of this utility model is as follows: After the powdered magnesium oxide is granulated, it is fed into the impurity removal tank 1 by the operator through the feed port 2;

[0027] Driven by the rotating motor 10, the electric magnetic rod 8 begins to rotate. The rotating magnetic rod not only solves the problem of material bridging, but also uses its electromagnetic force to adsorb magnetic impurities that enter the impurity removal tank 1. The design of the conductive slip ring ensures that the electric magnetic rod 8 can maintain an electrical connection with the external power supply during the rotation process, thereby continuously generating magnetic force to adsorb impurities.

[0028] When the electric magnetic rod 8 adsorbs a certain amount of material or reaches the preset impurity removal time, the electric telescopic rod 13 starts to work. The electric telescopic rod 13 pushes the side moving plate 6 and the magnetic rod rotating disk 7 on it, so that the electric magnetic rod 8 is slowly pushed out of the impurity removal barrel 1. During or after the push-out process, the external power supply is disconnected to make the electric magnetic rod 8 lose its magnetic force. At this time, the magnetic metal impurities adsorbed on the magnetic rod automatically fall off for easy collection.

[0029] Impurities are screened by the sieving filter 18. The magnesium oxide particles, due to their larger diameter, are retained above the filter screen, while the smaller impurities pass through the filter screen and fall to the bottom of the impurity collection box 14. At the same time, the vibration motor 19 starts to work, driving the sieving filter 18 to sieve up and down repeatedly, further enhancing the impurity removal effect.

[0030] After screening, the granular magnesium oxide can be smoothly discharged from the particle outlet 3 because the height of the sieve filter screen 18 and the bottom wall of the particle outlet 3 are matched.

[0031] When impurities accumulate to a certain level in the impurity collection box 14, the operator can open the discharge port by rotating the collection box sealing cover 15 to discharge the impurities and clean the impurity collection box 14. The flange connection design between the impurity output port 4 and the impurity collection port 16 facilitates quick disassembly and sealing, ensuring that impurities can smoothly and without contamination enter the impurity collection box 14.

[0032] After completing one impurity removal process, the operator reinserts the electric drive magnetic rod 8 into the impurity removal barrel 1 and shuts down all components. After the device is reset, the next particulate magnesium oxide impurity removal operation can be carried out.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
