[0001] The present invention relates to the technical field of anode baking furnaces, and in particular to an energy-saving and consumption-reducing anode baking furnace. Background Art

[0002] The anode baking furnace is one of the important equipment in the pre-baked anode baking production process. The sealing and heat preservation performance of each component of the baking furnace directly affects the energy consumption of the baking furnace and the quality of the pre-baked anode products.

[0003] When the existing baking furnace is feeding or discharging materials, it is easy to cause a large amount of heat loss, resulting in a decrease in the temperature inside the furnace. Furthermore, more energy is required to reheat the furnace to reach the baking temperature. Therefore, it is crucial to ensure that the heat loss is small during the feeding and discharging process of the baking furnace to achieve the purpose of energy saving and consumption reduction.

[0023] Refer to Figures 1-6 As shown in the figure, an anode baking furnace for energy conservation and consumption reduction provided by the present invention: An anode baking furnace for energy conservation and consumption reduction includes a furnace body 1, a top cover 2, a feed inlet 3, a discharge outlet 4 and a discharge device 6. The top cover 2 is fixedly connected to the top end of the furnace body 1. The feed inlet 3 is located at the top end of the top cover 2. The discharge outlet 4 is located at the right end of the furnace body 1. The discharge device 6 is located inside the furnace body 1. The feed inlet 3 includes a housing one 31, a feed baffle one 32, a feed handle one 33, a feed handle two 34, a feed baffle two 35, a limit block one 36 and a limit block two 38. The housing one 31 is communicated with the furnace body 1. Slide grooves one 37 and two 39 are respectively opened at the front and rear ends of the housing one 31. A limit block one 36 is slidably connected in the slide groove one 37. A feed baffle one 32 is fixedly connected between the two limit blocks one 36. A limit block two 38 is slidably connected in the slide groove two 39. A feed baffle two 35 is fixedly connected between the two limit blocks two 38. Both the feed baffle one 32 and the feed baffle two 35 pass through the left end of the housing one 31 and are slidably connected to the housing one 31. The parts of the feed baffle one 32 and the feed baffle two 35 located outside the housing one 31 are respectively fixedly connected with a feed handle one 33 and a feed handle two 34 at the top.

[0024] The discharge port 4 includes a second housing 41, a first discharge baffle 42, a first discharge handle 43, a second discharge handle 44, a heat insulation layer 45, a second discharge baffle 46, a third limiting block 47 and a fourth limiting block 49. The second housing 41 is communicated with the furnace body 1. Chute three 48 and chute four 410 are provided at both the front and rear ends of the second housing 41. The third limiting block 47 is slidably connected in the chute three 48. The second discharge baffle 46 is fixedly connected between the two third limiting blocks 47. A heat insulation layer 45 is provided at one end of the second discharge baffle 46 close to the furnace body 1. The fourth limiting block 49 is slidably connected in the chute four 410. The first discharge baffle 42 is fixedly connected between the two fourth limiting blocks 49. Both the first discharge baffle 42 and the second discharge baffle 46 pass through the top end of the second housing 41 and are slidably connected with the second housing 41. The right ends of the parts of the first discharge baffle 42 and the discharge baffle 46 outside the second housing 41 are respectively fixedly connected with the first discharge handle 43 and the second discharge handle 44. Through this embodiment, when discharging materials, first pull up the second discharge handle 44 to make the second discharge baffle 46 and the heat insulation layer 45 rise together, so that the materials enter the chamber formed between the two baffles of the discharge port 4. After closing the second discharge baffle 46, open the first discharge baffle 42 through the first discharge handle 43 to collect the materials; when feeding materials, first open the first feed baffle 32 by pulling the first feed handle 33 to the left, load the materials and store them on the second feed baffle 35. After closing the first feed baffle 32, open the second feed baffle 35 through the second feed handle 34 to make the materials fall into the furnace body 1 for roasting. Whether in the process of feeding or discharging materials, the inside of the furnace body 1 is not directly in contact with the outside of the furnace body 1, so that the heat loss inside the furnace body 1 is small, and the heat required to reheat the furnace to the roasting temperature is reduced, thus achieving the purpose of energy conservation and consumption reduction.

[0025] The furnace body 1 includes insulating bricks 11, aluminum silicate fiber boards 12, aluminum silicate fiber blankets 13 and flue walls 14. The aluminum silicate fiber boards 12 are provided outside the flue walls 14. A casting joint is formed between the aluminum silicate fiber boards 12 and the flue walls 14, and the casting joint is filled with aluminum silicate fiber blankets 13. The insulating bricks 11 are provided outside the aluminum silicate fiber boards 12. Filling the aluminum silicate fiber blankets 13 between the aluminum silicate fiber boards 12 and the flue walls 14 fully insulates the roasting furnace, so that the temperature loss in the furnace is small, thereby reducing the heat required to maintain the temperature in the furnace. The insulating bricks 11 provided on the outermost side of the furnace body 1 have the properties of high pressure resistance and poor heat conductivity. Under the condition of ensuring stable roasting of the roasting furnace, the temperature loss in the furnace is reduced, and the purpose of energy conservation and consumption reduction is achieved.

[0026] The top cover 2 includes a heat insulation plate 21 and a cover plate 22. The top end of the furnace body 1 is fixedly connected to the heat insulation plate 21, and the top end of the heat insulation plate 21 is fixedly connected to the cover plate 22. The heat insulation plate 21 is provided with a plurality of smoke exhaust holes 23, and the bottom end of the cover plate 22 is provided with a flue 24. The flue 24 communicates with the furnace body 1 through the smoke exhaust holes 23. The heat insulation plate 21 can effectively prevent heat dissipation. By providing a plurality of smoke exhaust holes 23, the smoke generated during roasting in the furnace body 1 enters the flue 24 through the smoke exhaust holes 23, preventing excessive soot in the furnace from affecting the roasting efficiency and the yield of the product.

[0027] A chimney 5 is fixedly connected to the top end of the cover plate 22, and the chimney 5 communicates with the flue 24. The chimney 5 is arranged in a staggered manner with the smoke exhaust holes 23. The purpose is that the heat lost with the flue gas can be cached after entering the flue, avoiding the direct discharge of heat outside the roasting furnace, thereby reducing heat loss.

[0028] The discharging device 6 includes an electric telescopic rod 61 and a roasting mesh 62. The front and rear ends of the right side of the roasting mesh 62 are rotatably connected to the furnace body 1 through rotating shafts. The electric telescopic rod 61 is fixedly connected to the bottom end inside the furnace body 1, and the output end of the electric telescopic rod 61 is hinged to the bottom end of the roasting mesh 62. The size of the roasting mesh 62 fits the inside of the furnace body 1, ensuring that all the materials can fall onto the roasting mesh 62 after falling from the second feeding baffle 35, thereby ensuring the yield of the roasted product. When discharging is required after roasting, the second discharging baffle 46 is opened, and the electric telescopic rod 61 is started. The output end of the electric telescopic rod 61 is hinged to the roasting mesh 62. Therefore, when the electric telescopic rod 61 rises, the roasting mesh 62 rotates under the action of the rotating shaft, so as to pour the product into the discharging port 4. The bottom end of the discharging port 4 is inclined downward to the right, ensuring that the product enters the discharging port 4.

[0029] An installation hole is opened at the bottom end inside the furnace body 1, and a heat insulation sleeve is fixedly connected inside the installation hole. The electric telescopic rod 61 is located inside the heat insulation sleeve. The heat insulation sleeve is used to protect the electric telescopic rod 61 from the influence of high temperature, thereby extending its service life.

[0030] Working principle: In the present invention, a furnace body 1 is formed by arranging a flue wall 14, a refractory fiber board 12, and insulating bricks 11, and a refractory fiber blanket 13 is filled between the refractory fiber board 12 and the flue wall 14, so that the whole furnace body 1 has good heat insulation effect, reduces the heat loss in the furnace, and reduces the heat required to maintain roasting; by arranging a heat insulation plate 21 and a cover plate 22 at the top of the furnace body 1, and opening a plurality of smoke exhaust holes 23 on the heat insulation plate 21, the smoke generated by roasting in the furnace enters the flue 24 opened by the cover plate 22 along the smoke exhaust holes 23 and is discharged through the chimney 5. The chimney 5 is arranged in a staggered manner with the smoke exhaust holes 23, aiming to cache the heat lost with the smoke after it enters the flue and prevent the heat from being directly discharged outside the roasting furnace, thereby reducing the heat loss; by arranging a feed inlet 3 and a discharge outlet 4, when feeding is required, first pull the feed handle 1 33 to the left to open the feed baffle 1 32, load the material and store it on the feed baffle 2 35. After closing the feed baffle 1 32, open the feed baffle 2 35 by the feed handle 2 34 to make the material fall onto the roasting mesh 62 in the furnace body 1 for roasting. When discharging is required, first pull the discharge handle 2 44 upward to make the discharge baffle 2 46 and the heat insulation layer 45 rise together, and start the electric telescopic rod 61. The output end of the electric telescopic rod 61 is hinged to the roasting mesh 62. Therefore, when the electric telescopic rod 61 rises, the roasting mesh 62 rotates under the action of the rotating shaft, so as to pour the product into the discharge outlet 4. The bottom end of the discharge outlet 4 is inclined downward to the right to ensure that the product enters the chamber formed between the two baffles of the discharge outlet 4. After closing the discharge baffle 2 46, open the discharge baffle 1 42 by the discharge handle 1 43 to collect the material; during the feeding or discharging process of this energy-saving and consumption-reducing anode roasting furnace, the inside of the furnace body 1 is not in direct contact with the outside of the furnace body 1, so that the heat loss inside the furnace body 1 is small, and the heat required to reheat the furnace to the roasting temperature is reduced, thereby achieving the purpose of energy saving and consumption reduction.
