[0062] The following describes an aluminum rod energy-saving heating furnace and an aluminum rod energy-saving heating method according to embodiments of the present invention in conjunction with the accompanying drawings.

[0063] Reference Figures 1 to 5 The present invention aims to provide an embodiment of an aluminum rod energy-saving heating furnace.

[0064] In this embodiment, the aluminum rod energy-saving heating furnace mainly includes a furnace body 110 .

[0065] In some specific embodiments of the present invention, the furnace body 110 may include walls formed by stacking insulation bricks to reduce heat loss and lower energy consumption.

[0066] In some specific embodiments of the present invention, the furnace body 110 may include a steel structure arranged outside the wall to improve the stability of the furnace body 110 and avoid collapse.

[0067] In this embodiment, the furnace body 110 has a material inlet 120 and a material outlet 130 .

[0068] In some specific embodiments of the present invention, the feed port 120 and the discharge port 130 may be long rectangular shapes, so that the aluminum rod 100 rolls along its own radial direction to pass through the feed port 120 and the discharge port 130 .

[0069] In some specific embodiments of the present invention, the feed port 120 and the discharge port 130 can be circular holes, so that the aluminum rod 100 moves along its own axis to pass through the feed port 120 and the discharge port 130, so that the cross-sectional area of ​​the feed port 120 and the discharge port 130 is minimized to reduce heat loss.

[0070] A conveying mechanism is provided in the furnace body 110, and the conveying mechanism is used to convey the aluminum rod 100 from the feed port 120 to the discharge port 130. The conveying mechanism includes a rolling support assembly, and the rolling support assembly includes a plurality of inclined support rod groups, and the aluminum rod 100 rolls along the inclined support rod groups.

[0071] In some specific embodiments of the present invention, the conveying mechanism can include a feed support wheel group 140 and a discharge support wheel group 150, and the feed support wheel group 140 and the discharge support wheel group 150 each include a plurality of support wheels arranged along the length direction of the aluminum rod 100 to meet the needs of the aluminum rod 100 entering the feed port 120 and being discharged from the discharge port 130 along its own length direction.

[0072] In some specific embodiments of the present invention, the roller support assembly can be arranged between the feed support wheel group 140 and the discharge support wheel group 150, and the roller support assembly includes a plurality of side-by-side feed lifting rods 160 and a plurality of side-by-side discharge lifting rods 170, and a plurality of inclined support rod groups are located between the plurality of feed lifting rods 160 and the plurality of discharge lifting rods 170.

[0073] During use, when the feed lifting rod 160 lifts the aluminum rod 100, the aluminum rod 100 moves away from the feed support wheel group 140 and rolls along its own radial direction to the inclined support rod group; when the discharging lifting rod 170 lowers the aluminum rod 100, the aluminum rod 100 rolls and descends from the inclined support rod group to the discharging support wheel group 150.

[0074] In this embodiment, the number of the oblique support rod groups is two, which not only meets the transportation and heating needs but also reduces the occupied space.

[0075] In some specific embodiments of the present invention, a plurality of inclined support rod groups may include a first inclined support assembly, the first inclined support assembly includes a plurality of side-by-side first inclined support rods 180, the top ends of the first inclined support rods 180 are arranged close to the feed support wheel group 140, and the bottom ends of the first inclined support rods 180 are arranged away from the feed support wheel.

[0076] At the same time, the multiple inclined support rod groups also include a second inclined support assembly, the second inclined support assembly includes a plurality of side-by-side second inclined support rods 190, the top end of the second inclined support rod 190 is arranged close to the bottom end of the first inclined support rod 180, the bottom end of the second inclined support rod 190 is arranged close to the discharging support wheel group 150, and a plurality of side-by-side rotating trays 200 are arranged between the bottom end of the first inclined support rod 180 and the top end of the second inclined support rod 190, the rotating tray 200 is provided with a first notch 210 for accommodating the aluminum rod 100, the first notch 210 is used to accommodate the aluminum rod 100 and transfer from the first inclined support rod 180 to the second inclined support rod 190, and the top end of the second inclined support rod 190 is provided with a limiting plate 220 that cooperates with the first notch 210 to limit the material.

[0077] Therefore, the aluminum rod 100 rolls along the first inclined support rod 180 into the first notch 210 of the rotating disk 200, and the first notch 210 and the limiting plate 220 cooperate to transfer the aluminum rod 100 to the second inclined support rod 190, and the aluminum rod 100 then rolls along the second inclined support rod 190 to the discharge lifting rod 170.

[0078] A heating mechanism is also provided in the furnace body 110, including at least one row of combustion nozzles 230, wherein the row of combustion nozzles 230 is arranged along the length direction of the aluminum rod 100 and is located below an inclined support rod group to heat the aluminum rod 100 on the inclined support rod group.

[0079] In some specific embodiments of the present invention, the heating mechanism may be disposed below the first inclined support assembly. In this embodiment, the heating mechanism is disposed below the second inclined support assembly.

[0080] Reference Figure 2A lifting and flipping device is also provided in the furnace body 110. The lifting and flipping device is configured on the second inclined support assembly. The lifting and flipping device is located above a row of combustion nozzles 230. The lifting and flipping device includes a lifting mechanism and a flipping mechanism.

[0081] Specifically, the lifting mechanism includes a lifting frame 240 , and the lifting frame 240 is provided with a positioning groove 250 . The positioning groove 250 is open upward to position the aluminum rod 100 .

[0082] In some specific embodiments of the present invention, the lifting frame 240 can include a vertical plate, a positioning groove 250 is set on the top edge of the vertical plate, and two horizontal side edges of the vertical plate are connected with V-shaped plates 350. The two V-shaped plates 350 are arranged along the rolling direction of the aluminum rod 100, and the opening directions of the two V-shaped plates 350 are set in opposite directions.

[0083] It is easy to understand that, by providing a vertical plate, this embodiment not only meets the need to provide a positioning groove 250 to position and support the aluminum rod 100, but also reduces the physical space and reduces obstruction without affecting the heating of the aluminum rod 100.

[0084] The V-shaped plate 350 can limit the vertical plate, improve the strength of the vertical plate, and prevent the vertical plate from tilting. At the same time, the V-shaped plate 350 can abut the aluminum rod 100 to prevent the aluminum rod 100 from rolling, so that the aluminum rod 100 passes through the lifting frame 240 in order, and the vertical plate and the aluminum rod 100 are prevented from colliding and cracking.

[0085] As for the flipping mechanism, the flipping mechanism includes two flipping components, which are located at both ends of the aluminum rod 100. The flipping components include a flipping tube 260 for accommodating the ends of the aluminum rod 100 and a first motor for driving the flipping tube 260 to rotate. The first motor is located outside the furnace body 110. The output shaft of the first motor passes through the furnace body 110 to connect to the flipping tube 260. The flipping tube 260 has a radial notch 270.

[0086] During use, when the lifting frame 240 rises, the end of the aluminum rod 100 enters the turning tube 260 through the radial notch 270, and the turning tube 260 drives the aluminum rod 100 to rotate around its own axis to evenly heat the aluminum rod 100.

[0087] In some specific embodiments of the present invention, the lifting frame 240 can be kept at a corresponding height, so that when the flip tube 260 rotates, the aluminum rod 100 will not fall from the radial notch 270, ensuring that the process of rotating the aluminum rod 100 proceeds smoothly.

[0088] exist Figure 1 In the figure, the lifting mechanism, the turning mechanism and the combustion nozzle 230 overlap due to the relationship of the view, but because the lifting mechanism, the turning mechanism and the combustion nozzle 230 are staggered in the length direction of the aluminum rod 100, their respective operations do not affect each other.

[0089] In some specific embodiments of the present invention, the inner diameter of the flip tube 260 can be made larger than the outer diameter of the aluminum rod 100, and at the same time, the aluminum rod 100 can rotate freely in the flip tube 260, so that the flip tube 260 rotates and the aluminum rod 100 follows the rolling.

[0090] Reference Figure 3 In some specific embodiments of the present invention, an electric heater 280 and a separation cover 290 for separating the electric heater 280 from the aluminum rod 100 may be provided inside the end of the flip tube 260 close to the first motor.

[0091] It is easy to understand that, in this embodiment, by providing the electric heater 280 , the ends of the aluminum rod 100 can be heated, thereby reducing the temperature difference between the two ends of the aluminum rod 100 and the middle of the aluminum rod 100 .

[0092] The partition cover 290 can prevent the aluminum rod 100 from touching the electric heater 280, thereby protecting the electric heater 280 and facilitating heating of the aluminum rod 100 by heat radiation.

[0093] In some specific embodiments of the present invention, the flip tube 260 can be rotated forward and reversed to reduce the difficulty of wire setting.

[0094] In some specific embodiments of the present invention, a conductive ring may be provided to overcome the wire winding problem, and the conductive ring is a common structure in the power supply field and will not be described in detail.

[0095] Reference Figure 4 In some specific embodiments of the present invention, the lifting frame 240 can be provided with two C-shaped blanking frames 300, and the two C-shaped blanking frames 300 are located in the directions opposite to each other in the two positioning grooves 250 with the largest distance. The bottom of the C-shaped blanking frame 300 is connected to the lifting frame 240, and the inside of the C-shaped blanking frame 300 is used to avoid the end of the aluminum rod 100. The C-shaped blanking frame 300 is set at an angle relative to the aluminum rod 100, and the top of the C-shaped blanking frame 300 is used to abut the top of the aluminum rod 100, so that the aluminum rod 100 falls from the flip tube 260 to the positioning groove 250 or the inclined support rod group.

[0096] It is easy to understand that, by providing a C-shaped blanking rack 300, this embodiment can overcome the defect that the outer diameter of the aluminum rod 100 is almost the same as the radial notch 270 of the flip tube 260 and is difficult to fall out of the radial notch 270, and can also overcome the defect that the radial notch 270 of the flip tube 260 has a small angle deviation in direction and makes it difficult for the aluminum rod 100 to fall out of the radial notch 270, thereby meeting the heating requirements of aluminum rods 100 of different specifications.

[0097] In some specific embodiments of the present invention, the lifting frame 240 may be configured with multiple sets of positioning grooves 250 , and the flipping mechanism may also have multiple sets to synchronously lift multiple aluminum bars 100 and flip them for heating.

[0098] Reference Figure 5 In some specific embodiments of the present invention, the second inclined support rod 190 can be provided with a plurality of heat transfer channels, and the plurality of heat transfer channels are arranged along the length direction of the second inclined support rod 190. The heat transfer channels include an upper air outlet and a lower air inlet connected to the upper air outlet. The lower air inlet is used to introduce hot air generated by the combustion of the combustion nozzle 230, and the upper air outlet is used to discharge the hot air to the aluminum rod 100, so as to heat the portion of the aluminum rod 100 blocked by the second inclined support rod 190.

[0099] In some specific embodiments of the present invention, the second inclined support rod 190 can be a hollow profile, and hot air can be conducted to various positions of the second inclined support rod 190 to delay the cooling of the aluminum rod 100 by conducting heat to the second inclined support rod 190 .

[0100] Reference Figure 1 In some specific embodiments of the present invention, the furnace body 110 can be provided with two hot air outlets 310, and the hot air outlets 310 are arranged correspondingly above the flip tube 260. The furnace body 110 is also provided with a circulating air duct 320 connected to the hot air outlet 310, an induced draft inlet and an induced draft fan 330 located on the circulating air duct 320, and an air inlet 340 is provided at one end of the circulating air duct 320 away from the hot air outlet 310, and the air inlet 340 is arranged in the middle position below a row of combustion nozzles 230.

[0101] It is easy to understand that, in this embodiment, by properly arranging the hot air outlet 310 and the air inlet 340 , the air flow direction can be improved so as to balance the temperature difference between the two ends of the aluminum rod 100 and the middle of the aluminum rod 100 , and evenly heat the aluminum rod 100 .

[0102] The provision of the circulating air duct 320 can heat the air in advance or preheat the air, thereby increasing the temperature of the air, reducing energy consumption, and making the temperature inside the furnace body 110 higher, thereby meeting the need for heating the aluminum rod 100 .

[0103] Reference Figure 6 The present invention aims to provide an embodiment of an aluminum rod energy-saving heating method, focusing on the use of the above-mentioned aluminum rod energy-saving heating furnace.

[0104] Specifically, the heating method includes:

[0105] In step S001 , the aluminum rod 100 moves along its own length direction to pass through the feed port 120 .

[0106] In some specific embodiments of the present invention, a push rod or a conveying wheel may be provided outside the furnace body 110 , and the push rod pushes the aluminum rod 100 into the feed port 120 , or the conveying wheel rotates and supports to transfer the aluminum rod 100 into the feed port 120 .

[0107] Step S002 , the portion of the aluminum rod 100 that enters the furnace body 110 is supported by the support wheels of the feed support wheel group 140 to continue moving. When the aluminum rod 100 completely enters the furnace body 110 , the aluminum rod 100 stops.

[0108] In some specific embodiments of the present invention, the feed support wheel set 140 can be driven to rotate by a motor, and the structure of supporting and conveying the aluminum rod 100 outside the furnace body 110 can save power and optimize the power configuration.

[0109] In some specific embodiments of the present invention, the support wheels of the feed support wheel set 140 can be braked to stop the aluminum rod 100.

[0110] In some specific embodiments of the present invention, a baffle may be disposed in the furnace body 110 , and the baffle abuts against the end of the aluminum rod 100 to stop the aluminum rod 100 .

[0111] Step S003 , the feed lifting rod 160 swings upward, the feed lifting rod 160 abuts against and lifts the aluminum rod 100 , and the aluminum rod 100 rolls along the feed lifting rod 160 to the first inclined support rod 180 .

[0112] In some specific embodiments of the present invention, the feed lifting rod 160 can be connected to a cylinder, a rotating disk, etc. through a connecting rod to drive the feed lifting rod 160 to lift.

[0113] In some specific embodiments of the present invention, one end of the feed lifting rod 160 may be hinged to the first inclined support rod 180 , so that the aluminum rod 100 can smoothly roll to the first inclined support rod 180 .

[0114] In some specific embodiments of the present invention, an upward hook may be provided at the other end of the feed lifting rod 160 to prevent the aluminum rod 100 from falling and failing to achieve correct rolling of the aluminum rod 100 .

[0115] In some specific embodiments of the present invention, the feed lifting rod 160 can be arranged between the support wheels of the feed support wheel group 140 to support the aluminum rod 100 at multiple points, balance the force, and avoid deformation of the feed lifting rod 160.

[0116] In step S004 , the aluminum rod 100 rolls along the first inclined support rod 180 to the rotating material tray 200 , and the rotating material tray 200 allows the aluminum rod 100 to roll into the first notch 210 .

[0117] In some specific embodiments of the present invention, the inclination of the first inclined support rod 180 can be reduced, so that the aluminum rods 100 can roll automatically and the aluminum rods 100 can be prevented from colliding with each other and crossing the rotating tray 200 during initial loading.

[0118] Step S005 , the rotating disc 200 continues to rotate, and the first notch 210 and the limiting plate 220 cooperate to transfer the aluminum rod 100 to the top end of the second inclined support rod 190 .

[0119] In some specific embodiments of the present invention, the rotating material tray 200 may have two first notches 210 to increase the space of the first notches 210 to facilitate the passage of aluminum bars 100 with larger diameters. At the same time, it is also beneficial to reduce the diameter of the rotating material tray 200 and reduce the occupied space.

[0120] In some specific embodiments of the present invention, the side edge of the limiting plate 220 can be matched with the outer diameter of the rotating disc 200 to avoid jamming.

[0121] In some specific embodiments of the present invention, the limiting plate 220 and the rotating material tray 200 can be staggered along the length direction of the aluminum rod 100 to facilitate disassembly, assembly and maintenance.

[0122] Step S006 , the aluminum rod 100 rolls down along the second inclined support rod 190 , and the combustion nozzle 230 burns to heat the aluminum rod 100 on the second inclined support rod 190 .

[0123] In some specific embodiments of the present invention, the combustion nozzle 230 can be burned first to increase the temperature in the furnace body 110 to avoid the furnace body 110 being too low in temperature to heat the aluminum rod 100 to a set temperature, or to allow the aluminum rod 100 to dissipate heat and cool down.

[0124] Step S007 , when the aluminum rod 100 touches the lifting frame 240 , the lifting frame 240 descends, so that the aluminum rod 100 is located in the positioning groove 250 .

[0125] In some specific embodiments of the present invention, when the aluminum rod 100 touches the lifting frame 240, the aluminum rod 100 stops and the lifting frame 240 descends, so that the aluminum rod 100 can roll into the positioning groove 250, thereby preventing the aluminum rod 100 from rolling toward the discharge lifting rod 170 without being fully heated.

[0126] Step S008 , the lifting frame 240 is lifted so that the aluminum rod 100 is separated from the second inclined support rod 190 .

[0127] In some specific embodiments of the present invention, the aluminum rod 100 may be lifted by several millimeters to prevent the aluminum rod 100 from being too far away from the combustion nozzle 230 and affecting the heating effect.

[0128] Step S009 , when the lifting frame 240 is lifted to the highest point, both ends of the aluminum rod 100 enter the turning tube 260 through the radial notch 270 .

[0129] In some specific embodiments of the present invention, the lifting frame 240 can lift the aluminum rod 100 into the radial notch 270, but avoid the low point of the positioning groove 250 being higher than the low point of the inner surface of the flip tube 260, so as to avoid contact between the positioning groove 250 and the aluminum rod 100 and affect the flipping of the aluminum rod 100.

[0130] In some specific embodiments of the present invention, the positioning groove 250 and the flip tube 260 can be staggered along the length direction of the aluminum rod 100 to avoid mutual interference.

[0131] In step S010 , the first motor drives the flip tube 260 to rotate, so as to drive the aluminum rod 100 to rotate around its own axis, so as to heat the aluminum rod 100 all around.

[0132] In some specific embodiments of the present invention, the lifting frame 240 can be lowered by one to two millimeters to prevent the low point of the positioning groove 250 from being higher than the low point of the inner surface of the flip tube 260. Therefore, it is convenient for the flip tube 260 to drive the aluminum rod 100 to rotate. At the same time, when the radial notch 270 faces downward and the aluminum rod 100 is seated in the positioning groove 250, the edge of the radial notch 270 can shovel the aluminum rod 100 back into the flip tube 260 without affecting the flipping of the aluminum rod 100.

[0133] At the same time, the lifting frame 240 rises to the highest point and then descends a certain distance, which makes it convenient for the aluminum rod 100 to enter the flip tube 260. At the same time, due to the rotation of the flip tube 260, the aluminum rod 100 will roll due to inertia, which is convenient for rotating and heating the aluminum rod 100 and makes it difficult for the aluminum rod 100 to escape from the flip tube 260.

[0134] When the radial notch 270 is facing upward or in other directions that are biased upward, the aluminum rod 100 is seated in the flip tube 260 due to gravity and there is no risk of falling off.

[0135] In some specific embodiments of the present invention, a portion of the hot air generated by the combustion of the combustion nozzle 230 can be blown toward the portion of the aluminum rod 100 supported by the second inclined support rod 190 through the lower air inlet and upper air outlet of the heat transfer channel.

[0136] In some specific embodiments of the present invention, the electric heater 280 can be powered on to increase the temperature, and the electric heater 280 radiates heat to the aluminum rod 100 through the separation cover 290 .

[0137] In some specific embodiments of the present invention, the air inlet 340 can be used to introduce air to meet the combustion requirements of the combustion nozzle 230. At the same time, the hot air is dispersed to the aluminum rod 100 and both ends of the aluminum rod 100 to evenly heat the aluminum rod 100, and the hot air outlet 310 can accelerate and increase the hot air flowing to both ends of the aluminum rod 100.

[0138] In some specific embodiments of the present invention, the hot air can be returned to the furnace body 110 together with the newly introduced air through the circulating air duct 320 to heat the newly introduced air and increase the temperature in the furnace body 110, which is beneficial to energy saving and environmental protection.

[0139] Step S011 , when the turning tube 260 rotates a set number of times, the lifting frame 240 descends, and both ends of the aluminum rod 100 return to the positioning groove 250 through the radial notch 270 .

[0140] In some specific embodiments of the present invention, the C-shaped blanking rack 300 can press the top of the aluminum rod 100, and the two ends of the aluminum rod 100 return to the positioning groove 250 through the radial notch 270.

[0141] In step S012 , the lifting frame 240 continues to descend, and the aluminum rod 100 is seated on the second inclined support rod 190 and is separated from the positioning groove 250 .

[0142] In step S013 , the aluminum rod 100 continues to roll along the second inclined support rod 190 and rolls to the discharge lifting rod 170 .

[0143] In some specific embodiments of the present invention, one or two hooks may be provided on the discharge lifting rod 170 to prevent the aluminum rod 100 from rolling down, and also to facilitate the aluminum rod 100 to accurately land on the discharge supporting wheel.

[0144] Step S014 , the discharge lifting rod 170 descends so that the aluminum rod 100 is seated on the discharge supporting wheel assembly 150 .

[0145] In some specific embodiments of the present invention, a gas cylinder or an oil cylinder may be provided at the bottom of the discharge lifting rod 170, which not only meets the movement requirements of the discharge lifting rod 170, but also shortens the transmission route and reduces the occupied space.

[0146] Step S015 , the discharging support wheel assembly 150 rotates to discharge the aluminum rod 100 from the discharging port 130 .

[0147] In some specific embodiments of the present invention, the feed support wheel set 140 and the discharge support wheel set 150 can share power or be driven by the same motor to reduce power configuration.

[0148] Since step S001 , step S002 and step S015 are easy to understand and are limited by the size of the drawing, they are not shown in the workflow diagram.
