It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a large-scale ferrosilicon manganese submerged arc furnace hot charging and hot delivery device, such as... Figure 1-4As shown, the large-scale ferrosilicon manganese submerged arc furnace hot charging and hot delivery device includes: a rail transport vehicle body 1 for transporting ferrosilicon manganese alloy material processed by the submerged arc furnace; two mounting plates 2 disposed on the rail transport vehicle body 1, each mounting plate 2 having a connecting shaft 4 rotatably mounted on it, and a hot delivery box 3 for hot charging and hot delivery of the ferrosilicon manganese alloy material processed by the submerged arc furnace fixedly mounted on the two connecting shafts 4, and the hot delivery box 3 being provided with a feed pipe 5; a unloading mechanism disposed on the rail transport vehicle body 1 and the connecting shafts 4 for unloading the ferrosilicon manganese alloy material in the hot delivery box 3; and a shielding mechanism assembled on the hot delivery box 3 and the feed pipe 5 for shielding the top of the feed pipe 5.

[0023] In this embodiment, after the ferrosilicon alloy raw material is processed in the ferrosilicon submerged arc furnace, when the processed ferrosilicon alloy raw material solution needs to be transported to the next processing station, the hot delivery box 3 is first transported to the corresponding discharge position of the ferrosilicon submerged arc furnace by the rail transport vehicle body 1. The processed ferrosilicon alloy raw material is then placed into the hot delivery box 3 through the feed pipe 5. After the feeding is completed, the controller activates the shielding mechanism to shield the top of the feed pipe 5, thereby preventing the ferrosilicon alloy raw material from contacting oxygen and causing oxidation, improving the safety of hot charging and hot delivery of the ferrosilicon alloy raw material. Then, the hot delivery box 3 is transported by the rail transport vehicle body 1. The main body 1 transports the silicon-manganese alloy raw material in the hot delivery box 3 to the corresponding processing point. The track transport vehicle body 1 is fixed by the external equipment. Then, the controller opens the shielding mechanism to shield the top of the feed pipe 5. Then, the controller starts the unloading mechanism to unload the silicon-manganese alloy raw material in the hot delivery box 3 to the corresponding processing position. With this device, the silicon-manganese alloy raw material processed by the silicon-manganese submerged arc furnace can be hot-charged and hot-delivered. At the same time, it can avoid the problem of oxidation caused by the silicon-manganese alloy raw material coming into contact with oxygen during transportation, improve the safety of hot charging and hot delivery of silicon-manganese alloy raw material, and facilitate unloading.

[0024] In a further preferred embodiment of the present invention, the unloading mechanism includes: a first telescopic rod 6 mounted on the rail transport vehicle body 1; a connecting plate 7 fixedly sleeved on the connecting shaft 4, wherein the connecting plate 7 and the output shaft of the first telescopic rod 6 are hinged together.

[0025] In this embodiment, when using the unloading mechanism, the first telescopic rod 6 is activated by the controller. The output shaft of the first telescopic rod 6 pushes the connecting plate 7, and the connecting plate 7 drives the connecting shaft 4 to rotate, thereby causing the hot delivery box 3 to rotate and flip to a certain extent. This allows the silicon-manganese alloy raw material in the hot delivery box 3 to be discharged through the feed pipe 5, making unloading convenient and simple.

[0026] In a further preferred embodiment of this utility model, the shielding mechanism includes: a heat insulation cover 8 fixedly installed on the outer wall of one side of the feed pipe 5; a second telescopic rod 9 fixedly installed on the heat insulation cover 8, a connecting block 10 fixedly installed on the output shaft of the second telescopic rod 9, and a protective cover 11 for shielding and protecting the top of the feed pipe 5 fixedly installed on the connecting block 10; and a rotating mechanism assembled on the heat insulation cover 8 and the second telescopic rod 9 for rotating and adjusting the position of the protective cover 11.

[0027] In this embodiment, when using the shielding mechanism, the controller starts the rotating mechanism to drive the second telescopic rod 9 to rotate 180 degrees, thereby adjusting the protective cover 11 above the feed pipe 5. Then, the controller starts the second telescopic rod 9 to drive the protective cover 11 to move down, so that the protective cover 11 shields the top of the feed pipe 5, thereby avoiding the oxidation problem caused by the contact between the silicon manganese alloy raw material and oxygen, and improving the safety of hot charging and hot delivery of the silicon manganese alloy raw material. Similarly, by reversing the above steps, the protective cover 11 can be removed from shielding the feed pipe 5, thereby facilitating the discharge of the silicon manganese alloy raw material in the hot delivery box 3.

[0028] In a further preferred embodiment of the present invention, the rotating mechanism includes: a servo motor 12 fixedly installed inside the heat insulation cover 8; a mounting shaft 13 rotatably installed on the heat insulation cover 8, one end of the mounting shaft 13 being fixedly connected to the output shaft of the servo motor 12; and a mounting block 14 fixedly sleeved on the mounting shaft 13, the mounting block 14 being fixedly connected to the bottom of the second telescopic rod 9.

[0029] In this embodiment, when using the rotating mechanism, the servo motor 12 is started by the controller to drive the mounting block 14 on the mounting shaft 13 to rotate, thereby driving the protective cover 11 to rotate, which makes it easier to rotate and adjust the position of the protective cover 11.

[0030] In a further preferred embodiment of the present invention, a rock wool board 15 is provided on the hot delivery box 3, a glass fiber cotton board 16 is provided on one side of the rock wool board 15, and a magnesium carbon brick board 17 is provided on one side of the glass fiber cotton board 16.

[0031] In this embodiment, the rock wool board 15, glass fiber wool board 16 and magnesium carbon brick board 17 work together to effectively heat-insulate and heat-transfer the silicon manganese alloy raw material in the heat transfer box 3.

[0032] In a further preferred embodiment of the present invention, a third telescopic rod 18 is fixedly installed on the track transport vehicle body 1, and a base 19 is fixedly installed on the output shaft of the third telescopic rod 18. The top of the base 19 is fixedly connected to the bottom of the mounting plate 2, and the top of the base 19 is hinged to the bottom of the first telescopic rod 6.

[0033] In this embodiment, when it is necessary to adjust the height of the feed pipe 5, the controller can be used to activate the third telescopic rod 18 to move the hot delivery box 3 on the base 19, thereby allowing the feed pipe 5 to receive and discharge materials.

[0034] In a further preferred embodiment of the present invention, a heat insulation plate is provided on the hot delivery box 3, and the heat insulation plate is used to insulate the interior of the hot delivery box 3.

[0035] In this embodiment, the heat insulation plate can provide good heat insulation for the hot delivery box 3.
