[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0026] Example 1:

[0027] refer to Figures 1-2 This utility model provides an automated slag removal structure for a mill, comprising:

[0028] Support component 1, with a transition box 2 installed on its upper end;

[0029] The slag discharge box 5 is slidably installed on one side of the support member 1. The slag discharge box 5 is used to collect and temporarily store slag materials. The slag discharge box 5 is connected to the transition box 2.

[0030] Partition 8, which is installed inside the transition box 2, is used to seal and open the transition box 2;

[0031] The feeding component 9 is installed inside the slag discharge box 5 and is used for discharging and collecting slag.

[0032] A central controller 7 is installed on one side of the support component 1. The central controller 7 is electrically connected to the connecting box 66, the connecting column 67, the telescopic component 83, and the drive component 93.

[0033] The upper end of the transition box 2 is fixedly connected to the slag discharge pipe 3, and the input end of the slag discharge pipe 3 is installed at the slag discharge port of the mill.

[0034] The lower end of the transition box 2 is connected to the telescopic pipe 4, and the output end of the telescopic pipe 4 is connected to the upper end of the slag discharge box 5.

[0035] Detailed implementation: When the mill is grinding materials, the slag produced enters the transition box 2 through the slag discharge pipe 3, and is then transported to the inside of the slag discharge box 5 through the telescopic pipe 4. The slag is temporarily stored in the slag discharge box 5. At this time, the partition 8 is closed to keep the transition box 2 connected to the telescopic pipe 4. When the slag stored in the slag discharge box 5 exceeds the threshold, the partition 8 opens to seal the lower end of the transition box 2, and the feeding part 9 closes to discharge the slag inside the slag discharge box 5. At this time, the partition 8 and the lower end of the transition box 2 are sealed, which can reduce the pressure fluctuation and material flow instability of the mill during the slag discharge process, and help protect the integrity and stability of the equipment.

[0036] Example 2:

[0037] refer to Figures 2-4 The second embodiment of this utility model includes:

[0038] Support component 1, with a transition box 2 installed on its upper end;

[0039] The slag discharge box 5 is slidably installed on one side of the support 1. The slag discharge box 5 is used to collect and temporarily store slag. The slag discharge box 5 is connected to the transition box 2.

[0040] Control component 6 is installed at the lower end of slag discharge box 5. Control component 6 is used to control the automatic slag discharge of the slag discharge structure. Control component 6 includes a number of support blocks 61 evenly arranged at the lower end of slag discharge box 5. Support rods 62 are provided at the lower end of support blocks 61. Support cylinders 63 are slidably installed on the outer surface of support rods 62. Bottom rings 64 are provided at the lower end of support cylinders 63. Bottom rings 64 are installed at the lower end of support component 1. Elastic element 65 is provided between bottom rings 64 and support blocks 61. Connecting box 66 is provided at the upper end of support cylinder 63. Connecting post 67 is provided inside support blocks 61. Connecting post 67 and connecting box 66 are connected by a plug-in circuit.

[0041] Partition 8, which is installed inside the transition box 2, is used to seal and open the transition box 2;

[0042] The feeding component 9 is installed inside the slag discharge box 5 and is used for discharging and collecting slag.

[0043] The partition 8 includes a sealing plate 81 that is slidably installed inside the transition box 2. A support plate 82 is installed on one side of the transition box 2. A telescopic member 83 is provided on the upper end of the support plate 82. The output end of the telescopic member 83 is connected to one side of the sealing plate 81.

[0044] The unloading component 9 includes a baffle plate 91 that is slidably installed inside the slag discharge box 5. A support plate 92 is fixedly installed on one side of the slag discharge box 5. A driving component 93 is fixedly installed on the upper end of the support plate 92. The output end of the driving component 93 is connected to one side of the baffle plate 91.

[0045] A central controller 7 is installed on one side of the support component 1. The central controller 7 is electrically connected to the connecting box 66, the connecting column 67, the telescopic component 83, and the driving component 93. The telescopic component 83 and the driving component 93 include, but are not limited to, electric push rods and telescopic cylinders.

[0046] Detailed Implementation: As slag continues to enter the mill, the internal weight of the slag discharge box 5 gradually increases. This change exerts increasing pressure on the supporting structure, including the support block 61, support rod 62, and elastic element 65. Under this pressure, the elastic element 65 begins to gradually contract, while the support rod 62 slides downwards along the inside of the support cylinder 63. This sliding action causes the connecting column 67 and the entire slag discharge box 5 to descend. Simultaneously, the telescopic tube 4 extends accordingly to accommodate the descent distance of the slag discharge box 5.

[0047] When the slag discharge box 5 descends to the preset threshold, the connecting post 67 is precisely inserted into the connecting box 66, thus achieving circuit connection and transmitting this signal to the central controller 7. Upon receiving the signal, the central controller 7 automatically initiates a series of operations: First, it controls the telescopic component 83 to unfold, pushing the sealing plate 81 to seal the transition box 2; then, it opens the drive component 93, causing it to retract and pull the baffle plate 91 out from the lower end of the slag discharge box 5, thereby releasing the seal on the lower end of the slag discharge box 5 and allowing the slag to be smoothly discharged from the lower end of the slag discharge box 5.

[0048] This process will continue until a preset time is reached, sufficient for the slag discharge box 5 to completely discharge the slag inside. Under the action of the elastic potential energy of the elastic element 65, the slag discharge box 5 will begin to rise and gradually return to its original position. After the preset time is completed, the central controller 7 will also control the telescopic element 83 to retract, pulling back the sealing plate 81, thereby reconnecting the transition box 2 and the telescopic pipe 4. Subsequently, the drive element 93 will unfold again, pushing the baffle plate 91 back into the slag discharge box 5 to seal it, preparing for the next slag discharge process.

[0049] The automated slag discharge of the mill can be achieved through the control component 6, central controller 7, partition component 8, and discharge component 9, eliminating the need for manual intervention. This not only greatly improves work efficiency but also significantly enhances operational safety, reducing human error and accident risks. Secondly, the system can adaptively discharge slag based on mill efficiency and automatically adjust the height according to slag weight, adapting to variations in slag quantity and weight, thus improving system flexibility and adaptability and ensuring the accuracy and stability of the mill's slag discharge process. Finally, when the slag discharge box 5 descends to a preset threshold, the baffle plate 91 is pulled out by the drive component 93, allowing the slag to be discharged smoothly. The descent of the slag discharge box 5 reduces the slag discharge height, which helps reduce dust dispersion and diffusion.
