Description

Technical Field

[0001] The present invention relates to the technical field of reduction furnaces, and more specifically, it relates to a feeding and drying bin for a metal reduction furnace. Background Art

[0002] A metal reduction furnace is a device used to reduce metal oxides and perform reduction treatment on metal oxides. As a key high-temperature industrial device, its core function is to reduce metal oxides or ions to metals in a high-temperature environment. When a metal reduction furnace is in use, raw materials are usually transported into the interior of the reduction furnace through a feeding bin.

[0003] When existing metal reduction furnaces are in use, generally, the raw materials are first dried in a drying bin, and then the dried raw materials in the drying bin are lifted and added to the reduction furnace for reduction processing through a lifting device or the like. However, when the raw materials are processed and dried in the drying bin, they are directly stacked in the drying bin for heating, and the heat uniformity is general, resulting in poor drying uniformity of the raw materials; existing drying bins generally directly set heating devices in the drying bin or pass hot air into the drying bin through a single pipeline to heat and dry the stacked raw materials, and the heat distribution is uneven; when drying the raw materials with hot air, the exhaust is generally directly through the feeding pipe, and the exhaust efficiency is poor, and the water vapor is difficult to be discharged in time, resulting in the accumulation of water vapor in the drying bin, increasing the humidity in the drying bin and affecting the drying effect of the raw materials.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present invention provides a feed drying bin for a metal reduction furnace, which has the following beneficial effects:

[0017] First, by providing a motor, a belt, and a lifting box, when stirring the raw materials in the bin body, the motor drives the first rotating rod to rotate, thereby driving the belt and the lifting box to rotate, so as to disperse and carry upward the raw materials piled up in the bin body. After reaching the highest point, the raw materials fall downward and are dispersed, effectively preventing the raw materials from being overly piled up and caking, ensuring that the raw materials are loose, maintaining the uniformity of heat distribution, and improving the heating and drying effect on the raw materials.

[0018] Second, by providing a hot air device, a cloth air pipe, and a breathable plate, when inputting heat to dry the raw materials, the raw materials are evenly stacked on the breathable plate. The hot air device, in cooperation with the cloth air pipe and the air outlets, evenly inputs hot air into the bin body. Then the hot air passes through the breathable plate and fully contacts the raw materials to heat and dry the raw materials. The heat distribution is uniform, and the drying effect on the raw materials is better.

[0019] III. By setting up an exhaust pipe and a baffle strip, during exhaust, the baffle strip effectively prevents raw materials from being carried by hot air into the exhaust pipe. Through the exhaust pipe, water vapor can be quickly discharged from the bin body, preventing the hot air from flushing back when raw materials are added through the feed pipe of the bin body. Moreover, the mesh plate prevents external debris from entering the exhaust pipe, effectively preventing water vapor from accumulating in the bin body and improving the drying effect.

[0030] Please refer to Figures 1 - 5 , a feed drying bin for a metal reduction furnace, comprising a bin body 1, feet 2 and a feed pipe 3. The feet 2 and the feed pipe 3 are arranged on the bin body 1. An outlet pipe 4 is arranged on the bin body 1. A stirring mechanism and a hot air mechanism are arranged on the bin body 1. The stirring mechanism includes a machine base 5, a motor 6, a first rotating rod 7, a second rotating rod 8 and a belt 9. The machine base 5 is fixedly installed on the bin body 1. The motor 6 is fixedly installed on the machine base 5. The first rotating rod 7 is rotatably installed in the bin body 1 and connected to the output end of the motor 6. The second rotating rod 8 is rotatably installed in the bin body 1 and is located below the first rotating rod 7. The belt 9 is sleeved on the first rotating rod 7 and the second rotating rod 8. A lifting box 10 is fixedly arranged on the belt 9. Multiple groups of the lifting boxes 10 are arranged and evenly distributed on the belt 9. A convex strip 11 is fixedly arranged on the belt 9. A protective cover 12 is fixedly arranged in the bin body 1. The end of the protective cover 12 is in contact with the belt 9. A ring groove 13 is arranged on the protective cover 12. The convex strip 11 is located in the ring groove 13. A feed hopper 23 is arranged on the feed pipe 3. A top cover 24 is covered on the feed hopper 23.

[0031] Specifically, when stirring the raw materials in the bin body 1, the motor 6 drives the first rotating rod 7 to rotate, thereby driving the belt 9 and the lifting box 10 to rotate, so as to disperse and carry upward the raw materials piled up in the bin body 1. After reaching the highest point, the raw materials fall downward and are dispersed, effectively preventing the raw materials from excessive accumulation and caking, ensuring the looseness of the raw materials, maintaining the uniformity of heat distribution, and improving the heating and drying effect of the raw materials.

[0032] Please refer to Figure 2 , Figure 3 and Figure 6 , an implementation method for uniform hot air input. The hot air mechanism includes a hot air device 14, a hot air pipe 15, a air distribution pipe 16 and an air outlet 17. The hot air device 14 is fixedly installed on the bin body 1. The hot air pipe 15 is arranged at the output end of the hot air device 14 and inserted into the bin body 1. The air distribution pipe 16 is arranged in the bin body 1 and connected to the output end of the hot air pipe 15. Multiple groups of the air outlets 17 are arranged and evenly distributed on the air distribution pipe 16. A breathable plate 18 is fixedly arranged in the bin body 1.

A dust-proof net 25 is arranged at the air inlet end of the hot air device 14.

[0033] Specifically, when drying the raw materials by inputting heat, the raw materials are evenly stacked on the air-permeable plate 18. The hot air device 14, in cooperation with the air distribution duct 16 and the air outlet 17, evenly inputs hot air into the bin body 1. Then, the hot air passes through the air-permeable plate 18 and fully contacts the raw materials to heat and dry the raw materials.

[0034] Please refer to Figures 1 - 3 , the implementation method of draining water vapor. An exhaust pipe 20 is provided on the bin body 1. A mesh plate 21 is provided on the exhaust pipe 20. A stop strip 22 is provided at the connection between the exhaust pipe 20 and the bin body 1. A feed hopper 23 is provided on the feed pipe 3. A top cover 24 is provided on the feed hopper 23.

[0035] Specifically, during exhaust, the stop strip 22 effectively prevents the raw materials from being carried by the hot air into the exhaust pipe 20. Through the exhaust pipe 20, the water vapor can be quickly discharged from the bin body 1, preventing the bin body 1 from being backflushed by the hot air when adding raw materials through the feed pipe 3. And the mesh plate 21 prevents external sundries from entering the exhaust pipe 20, effectively preventing the water vapor from accumulating in the bin body 1 and improving the drying effect.

[0036] In summary, when the overall equipment is in use:

[0037] When stirring the raw materials in the bin body 1, the motor 6 drives the first rotating rod 7 to rotate, thereby driving the belt 9 and the lifting box 10 to rotate, so as to disperse and carry upward the raw materials piled up in the bin body 1. After reaching the highest point, the raw materials fall downward and are dispersed, effectively preventing the raw materials from over-piling and caking, ensuring that the raw materials are loose, maintaining the uniformity of heat distribution, and improving the heating and drying effect on the raw materials.

[0038] When drying the raw materials by inputting heat, the raw materials are evenly stacked on the air-permeable plate 18. The hot air device 14, in cooperation with the air distribution duct 16 and the air outlet 17, evenly inputs hot air into the bin body 1. Then, the hot air passes through the air-permeable plate 18 and fully contacts the raw materials to heat and dry the raw materials. The heat distribution is uniform, and the drying effect on the raw materials is better.

[0039] During exhaust, the stop strip 22 effectively prevents the raw materials from being carried by the hot air into the exhaust pipe 20. Through the exhaust pipe 20, the water vapor can be quickly discharged from the bin body 1, preventing the bin body 1 from being backflushed by the hot air when adding raw materials through the feed pipe 3. And the mesh plate 21 prevents external sundries from entering the exhaust pipe 20, effectively preventing the water vapor from accumulating in the bin body 1 and improving the drying effect.
