Description

Technical Field

[0001] The invention relates to the technical field of mineral wool production, in particular to an electric heating furnace for producing mineral wool by utilizing silicon-manganese alloy hot molten slag and a feeding mechanism used in conjunction with the furnace. Background Art

[0002] Mineral wool is an inorganic fiber made of industrial slag such as slow-cooled slag from blast furnaces as the main raw material, and other materials are added to it through remelting and fiberization. It can be made into various products such as plates, tubes, and felts. It has multiple functions such as insulation, heat preservation, fire prevention, corrosion resistance, moisture resistance, sound absorption, and earthquake resistance. It is widely used in construction, industrial equipment, and transportation. For example, it can be used in building exterior wall insulation, interior wall fireproofing and sound insulation, industrial kilns and pipeline insulation, and ship insulation. The temperature of liquid blast furnace slag is above 1400℃, which is a good waste heat resource. The waste heat contained in each ton of blast furnace slag is equivalent to the heat generated by the complete combustion of 60Kg of standard coal. In order to develop the high added value of blast furnace slag, the liquid blast furnace slag is directly utilized. At present, the liquid blast furnace slag is reheated to more than 1500℃ in an electric heating furnace to form a melt. The melt is made into inorganic fibers after fiberization through a four-roll centrifuge and a high-pressure fan. In this process, an electric heating furnace is needed.

[0003] At present, there are mainly two types of electric heating furnaces on the market: DC electric heating furnaces and AC electric heating furnaces. Traditional DC electric heating furnaces are mostly powered by fixed anodes, that is, the cathode is on the top and the anode is on the bottom. Heat is only transferred longitudinally from top to bottom, and the area of ​​heat radiation is small. The anode is embedded in the lining of the bottom or side wall of the furnace, and is in a high-temperature molten environment for a long time, making it difficult to maintain and reducing its service life.

[0004] The Chinese patent with publication number CN110081703A discloses a closed DC ore-fired furnace without fixed anodes, including: a furnace body, a furnace cover, an electrode column system, a charging system, a flue gas outlet system, a power supply system, a cooling water system and a hydraulic system. The furnace body is used to accommodate furnace charge, and the electrode column system is used to heat and melt the furnace charge by using a DC arc. It includes a cathode and an anode, and both of them can freely adjust the depth of insertion into the furnace charge. The cathode and anode of this structure can move up and down and be inserted into the solid furnace charge without direct contact with the high-temperature melt. The electrode can also be pulled out of the furnace charge for easy maintenance.

[0005] However, after the ore is put into the traditional electric heating furnace, the ore between the cathode and the anode will melt faster, resulting in uneven melting. Although the ore in the furnace can be completely melted in the end, the melting efficiency obviously needs to be improved. Summary of the invention

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1- Fig.14 The embodiment of the present invention provides a technical solution: an electric heating furnace for producing mineral wool using silicon-manganese alloy hot molten slag, comprising a furnace body 1 and a cylindrical frame 14 arranged at the upper end of the furnace body 1, and a furnace cover can be detachably installed on the upper end of the cylindrical frame 14 to ensure that the furnace body 1 is in a relatively sealed environment, and also includes a limit plate 28, the limit plate 28 is fixed to the upper end of the furnace body 1, and an arc-shaped through groove 29 is opened on the limit plate 28, a rotating ring 15 is provided above the limit plate 28, and the rotating ring 15 is rotatably connected to the limit plate 28, preferably the limit plate 28 is made of high temperature resistant heat-insulating material, and a sealing member is provided at the connection between the limit plate 28 and the rotating ring 15, so that the inside of the furnace body 1 is in a sealed state, thereby reducing the oxidation rate of the electrode and extending the service life of the electrode.

[0040] In addition, the electric heating furnace for producing mineral wool using hot molten slag of silicon-manganese alloy provided in this embodiment also includes a connecting frame 17, which is installed on the rotating ring 15. The connecting frame 17 and the rotating ring 15 can rotate synchronously, and a cathode column 19 corresponding to the arc-shaped through groove 29 is installed on the connecting frame 17. The cathode column 19 is slidably connected to the connecting frame 17, and the lower end of the cathode column 19 passes through the rotating ring 15 and the arc-shaped through groove 29 in sequence and extends to the inside of the furnace body 1. In this solution, the rotating ring 15 rotates to drive the cathode column 19 on the connecting frame 17 to move inside the arc-shaped through groove 29, and the liquid blast furnace slag inside the furnace body 1 can be locally stirred through the cathode column 19, thereby accelerating the hot melting of the liquid blast furnace slag.

[0041] In order to facilitate the input of liquid blast furnace slag into the furnace body 1, the electric furnace for producing mineral wool using silicon-manganese alloy hot molten slag provided in this embodiment also includes a feed pipe 11, which is installed in the middle of the limit plate 28, and a sleeve 24 is axially slidably installed on the outside of the feed pipe 11. It should be noted that a through hole adapted to the sleeve 24 is opened in the middle of the limit plate 28, and the through hole and the sleeve 24 are slidably connected. An installation groove 25 is opened on the sleeve 24, and an anode plate 26 is fixed on the inner side of the installation groove 25. The number of anode plates 26 and cathode columns 19 is the same.

[0042] Among them, the anode plate 26 is an arc-shaped structure, and the arc angle corresponding to the anode plate 26 is the same as the arc angle corresponding to the arc-shaped groove 29, so as to ensure that when the cathode column 19 moves inside the arc-shaped groove 29, the distance from the cathode column 19 to the anode plate 26 remains unchanged, thereby improving the stability of the arc generated between the cathode column 19 and the anode plate 26, thereby maintaining heat release stability. In addition, a transmission component is provided on the outside of the furnace body 1, and the transmission component is used to drive the cathode column 19 to reciprocate inside the arc-shaped groove 29, so that the arc generated between the cathode column 19 and the anode plate 26 moves with the cathode column 19, and the cathode column 19 rotates to make the generated arc move synchronously, thereby avoiding the arc from continuously heating a single position, further improving the heating effect, and making the material hot melt more uniform.

[0043] like Figure 1 - Figure 5 As shown, in order to realize the power supply of the cathode column 19 and the anode plate 26, the electric heating furnace for producing mineral wool using silicon-manganese alloy hot molten slag provided in this embodiment also includes a transformer 13, which is arranged on one side of the furnace body 1. The number of transformers 13 is consistent with the number of anode plates 26, and each transformer 13 is equipped with a rectifier, the anode of the rectifier is electrically connected to the corresponding anode plate 26, and the cathode of the rectifier is electrically connected to the corresponding cathode column 19, so as to independently power the corresponding anode plate 26 and arc-shaped slot 29, input AC power to the transformer 13, adjust it to the required voltage through the transformer 13, convert the AC power into DC power through the rectifier, and then input it to the anode plate 26 and the cathode column 19, so as to realize the independent power supply of each pair of electrodes and improve the stability of arc heat release. It should be noted that, compared with the prior art, after the AC furnace is improved into a DC furnace in this application, the power consumption is reduced by 15%, and the electrode consumption is 30% of the previous one.

[0044] like Figure 1 , Figure 2 , Figure 4 , Fig.12 , Fig.13 and Fig.14 As shown, the transmission assembly provided in this embodiment includes a rotating shaft 21, which is rotatably installed on one side of the cylindrical frame 14, and the rotating shaft 21 is parallel to the ground. The rotating shaft 21 is located at the inner side of the cylindrical frame 14 and is provided with a worm 22, and a second gear 23 is fixed to one end of the rotating shaft 21. A worm gear 16 is provided on the outer side of the rotating ring 15, and the worm gear 16 is meshed with the worm 22, and the maximum rotation angle of the worm gear 16 is the same as the arc corresponding to the anode plate 26, so that the rotation angle of the rotating ring 15 is not greater than the arc angle corresponding to the arc-shaped through groove 29.

[0045] In addition, the transmission assembly provided in this embodiment also includes a disc 36, which is rotatably installed on the outer side of the furnace body 1. A gear ring 37 is fixed on one side of the disc 36. An inner tooth 43 meshing with the second gear 23 is provided on the inner side of the gear ring 37. An incomplete gear 42 meshing with the second gear 23 is fixed at the middle position of the disc 36. It should be noted that the arc corresponding to the toothless area on the incomplete gear 42 provided in this embodiment is the same as the arc angle corresponding to the inner tooth 43, so as to ensure that the second gear 23 is always in a meshing state, thereby providing power for the rotating shaft 21 and improving the stability of the rotating shaft 21 during rotation. The arc length corresponding to the toothed area on the incomplete gear 42 is the same as the arc length corresponding to the inner tooth 43, so that the clockwise or counterclockwise rotation angle of the second gear 23 is consistent, so that the clockwise rotation angle of the rotating shaft 21 is the same as the counterclockwise rotation angle, which is conducive to maintaining the cathode column 19 in a stable reciprocating motion inside the arc-shaped through groove 29.

[0046] As Figure 1 - Figure 5 shown, to realize the input of liquid blast furnace slag into the interior of the furnace body 1, in this embodiment, fixing frames 2 are symmetrically fixed on the outer side of the furnace body 1. Preferably, the whole fixing frame 2 is in an inverted "U" - shaped structure. A first support frame 3 is fixed between the two fixing frames 2. At the upper end of the first support frame 3, there is a feeding hopper 5 communicated with the feeding pipeline 11. Preferably, a sealing filler is provided at the connection between the feeding hopper 5 and the feeding pipeline 11 to prevent liquid leakage. In addition, the inner side of the feeding hopper 5 is made of high - temperature - resistant material, and a heat - insulating layer is provided on the outer side of the feeding hopper 5 to reduce heat energy loss.

[0047] As Figure 1 - Figure 6 shown, a second support frame 4 is slidably installed between the two fixing frames 2 provided in this embodiment. The second support frame 4 is located below the first support frame 3, and a connecting sleeve is fixed at the lower end of the second support frame 4. The connecting sleeve is slidably connected with the feeding pipeline 11 and is fixedly connected with the upper end of the sleeve 24 for sealing the upper end of the sleeve 24. An anode lifting cylinder 12 for driving the second support frame 4 to slide on the fixing frame 2 is provided on the first support frame 3. The anode lifting cylinder 12 expands and contracts to adjust the feeding depth of the anode plate 26 into the furnace.

[0048] In addition, a connecting card slot 27 engaged with the connecting frame 17 is provided on the rotating ring 15. The snap - fit connection is beneficial to the disassembly of the connecting frame 17, thus facilitating the maintenance and repair of the equipment. A cathode lifting cylinder 18 is fixed on the upper surface of the connecting frame 17 on one side of the cathode column 19. The telescopic end of the cathode lifting cylinder 18 is provided with a connecting plate 20, and the other end of the connecting plate 20 is fixedly connected with the cathode column 19 on the same side. Preferably, a cathode clamp is provided on the connecting plate 20 to facilitate the loading and unloading of the cathode column 19. The cathode lifting cylinder 18 expands and contracts to adjust the feeding depth of the cathode column 19 into the furnace.

[0049] In this solution, the depth of the anode plate 26 inserted into the furnace body 1 is adjusted by the anode lifting cylinder 12, and the depth of the cathode column 19 inserted into the furnace body 1 is adjusted by the cathode lifting cylinder 18, so as to realize submerged - arc smelting, improve the heat energy utilization rate. In addition, it is also beneficial to the maintenance and repair of the anode plate 26 and the cathode column 19.

[0050] As Figure 1 - Figure 6 shown, one side of the furnace body 1 provided in this embodiment is provided with a slag outlet, and the other side of the furnace body 1 is provided with a discharge outlet. In addition, a furnace gas flue is installed at a position near the upper end of the furnace body 1. Optionally, a heat exchanger is provided on the furnace gas flue for recovering the heat energy in the flue gas to reduce heat energy loss. In addition, the end of the furnace gas flue is connected to an exhaust gas treatment tower, which is mainly used for treating exhaust gas to avoid environmental pollution by exhaust gas.

[0051] As Figure 1 、 Figure 2, Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the embodiment of the present invention also provides another technical solution: a feeding mechanism for use in an electric furnace that uses silicon-manganese alloy hot molten slag to produce mineral wool, including a receiving hopper 10, which is fixed on a fixed frame 2 and is connected to an upper hopper 5, and also includes a lifting frame 6, which is arranged on one side of the fixed frame 2, and a feeding assembly is provided on the lifting frame 6, and a limiting slide 30 is symmetrically fixed on one side of the lifting frame 6, and the limiting slide 30 is slidably connected to the fixed frame 2, and the limiting slide 30 slides on the fixed frame 2 to drive the feeding assembly on the lifting frame 6 to rise and fall, and after the feeding assembly reaches the receiving hopper 10, the material is put into the receiving hopper 10, and then enters the upper hopper 5, so as to realize the input of liquid blast furnace slag.

[0052] In order to realize the lifting and lowering of the lifting frame 6, the feeding mechanism provided in this embodiment also includes a double-axis motor 41, which is fixed to the lower end of one of the fixed frames 2, and a driving shaft 40 is provided at the output end of the double-axis motor 41. A linkage shaft 31 is rotatably connected to the upper inner end of the fixed frame 2. The linkage shaft 31 is parallel to the driving shaft 40, and sprockets 38 are installed on both ends of the linkage shaft 31 and the driving shaft 40. A chain 39 is provided between the two corresponding sprockets 38. In this scheme, it should be noted that both side edges of the fixed frame 2 are I-shaped structures to facilitate the accommodation of the chain 39. Accommodation cavities are provided at the upper and lower ends of the fixed frame 2, which are mainly used for the installation of the sprocket 38. In addition, a limit strip is also provided on the fixed frame 2, which is mainly used for limiting the lifting of the lifting frame 6 during lifting.

[0053] The inner side of the limiting slide plate 30 is fixed on the chain 39 so that the lifting frame 6 can be lifted and lowered as the chain 39 rotates.

[0054] like Figure 1 , Figure 2 , Fig.12 and Fig.13 As shown, one end of one of the driving shafts 40 passes through the fixed frame 2 and is installed with a driving wheel 33. A driven wheel 32 is also rotatably installed on the outer side of the fixed frame 2. A synchronous transmission belt 34 is provided between the driven wheel 32 and the driving wheel 33, and a first gear 35 is installed on the outer side of the driven wheel 32. The first gear 35 is meshed with the gear ring 37, so that the shaft 21 rotates while the lifting frame 6 is lifted. It should be noted that the outer diameter of the driving wheel 33 is preferably smaller than the outer diameter of the driven wheel 32, and the outer diameter of the first gear 35 is smaller than the outer diameters of the driven wheel 32 and the gear ring 37, so that the driving process of the shaft 21 belongs to a deceleration motion, thereby avoiding tooth collision due to excessive speed during the reversing process of the shaft 21, thereby improving the stability of the equipment during operation.

[0055] like Fig. 9- Fig.11 As shown, the feeding assembly provided in this embodiment includes a movable frame 8 hinged on the lifting frame 6, a feeding hopper 9 is fixed on the movable frame 8, a hydraulic cylinder 7 is hinged on the inner side of the lifting frame 6, and the telescopic end of the hydraulic cylinder 7 is rotatably connected to the bottom of the movable frame 8 to adjust the angle between the feeding hopper 9 and the horizontal plane, so that the material in the feeding hopper 9 can be fed into the receiving hopper 10.

[0056] When in use (working), the dual-axis motor 41 is started to rotate the driving shaft 40, and one of the sprockets 38 is rotated by driving the shaft 40. Through the transmission action between the sprocket 38 and the chain 39, the chain 39 drives the limiting slide plate 30 to slide on the inner side of the fixed frame 2, so that the lifting frame 6 rises. When the lifting frame 6 rises to the position of the receiving hopper 10, the hydraulic cylinder 7 is started, and the movable frame 8 is rotated by the hydraulic cylinder 7, so as to adjust the angle between the feeding hopper 9 and the horizontal plane, so that the material in the feeding hopper 9 is put into the receiving hopper 10, and the liquid blast furnace slag is sent to the loading hopper 5 through the receiving hopper 10 to complete the loading.

[0057] While loading, the driving shaft 40 will also drive the driving wheel 33 to rotate. Through the transmission effect among the driving wheel 33, the driven wheel 32, and the synchronous transmission belt 34, the first gear 35 rotates synchronously with the driven wheel 32. Through the meshing between the first gear 35 and the gear ring 37, the disc 36 rotates, thereby rotating the incomplete gear 42 and the inner teeth 43. In this process, since the arc corresponding to the toothless area on the incomplete gear 42 is the same as the arc angle corresponding to the inner teeth 43, the second gear 23 is always in a meshing state, thereby providing power for the rotating shaft 21, improving the stability of the rotating shaft 21 during rotation, and the arc length corresponding to the toothed area on the incomplete gear 42 is the same as the arc length corresponding to the inner teeth 43, so that the second gear 23 The clockwise or counterclockwise rotation angle is consistent, so that the clockwise rotation angle of the rotating shaft 21 is the same as the counterclockwise rotation angle, and the rotating shaft 21 further drives the worm 22 to rotate, and the worm gear 16 is engaged with the worm 22, so that the rotating ring 15 rotates, so as to drive the cathode column 19 on the connecting frame 17 to move inside the arc-shaped through groove 29. The liquid blast furnace slag inside the furnace body 1 can be locally stirred by the cathode column 19, thereby accelerating the hot melting of the liquid blast furnace slag. In addition, the rotation of the cathode column 19 makes the generated arc move synchronously, thereby avoiding the arc from continuously heating a single position, further improving the heating effect, and making the hot melting of the liquid blast furnace slag more uniform. This process is carried out during the loading process, so that the liquid blast furnace slag newly put into the furnace body 1 can be better hot melted.
