DETAILED DESCRIPTION

[0042] 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.

[0043] The processing furnace of the present invention belongs to a kind of high-efficiency energy-saving industry, and is a part of a special chemical furnace. It is used to heat the metal material for producing aluminum alloy ingots to a high temperature and melt it. The processing furnace is suitable for metal smelting, casting, steel smelting, copper smelting, metal refining and other fields.

[0044] Example 1

[0045] Refer to the instruction manual Figure 1-Figure 4A furnace for processing aluminum alloy ingots according to an embodiment of the present invention comprises a base 1 and a smelting part arranged on the top of the base 1, wherein the smelting part comprises a furnace body 2 fixedly mounted on the top of the base 1, a heat preservation cover 4 is fixedly sleeved on the outer side of the furnace body 2 to reduce the rapid loss of heat on the surface of the furnace body 2 during smelting, a furnace cover 3 is arranged on the top of the furnace body 2, a crucible 12 is arranged inside the furnace body 2, two seat blocks 14 are fixedly arranged on the top of the inner side of the furnace cover 3, two seat blocks 13 corresponding to the seat blocks 14 are fixedly arranged on the outer side of the crucible 12, and an L-shaped connecting rod 15 is hingedly installed between the corresponding seat blocks 13 and the seat blocks 14, and an air inlet pipe 10 for continuously introducing protective gas into the furnace body 22 and an exhaust pipe 11 for guiding the exhaust of waste gas generated during the smelting process are connected to the top of the furnace cover 3;

[0046] A loading mechanism 7 is provided on the top of the base 1 on one side of the furnace body 2, and an opening and unloading mechanism 5 for opening the furnace cover 3 and pouring out the molten liquid in the crucible 12 is installed between the furnace cover 3 and the heat preservation cover 4. A spring 16 is fixedly connected to the bottom of the crucible 12, and a counterweight 17 is fixedly connected to one end of the spring 16. Two limiting plates 18 for preventing the crucible 12 from swinging are fixedly installed on the inner side of the furnace body 2. The connecting line between the center points of the two limiting plates 18 and the connecting line between the center points of the two L-shaped connecting rods 15 are arranged in a cross. When the furnace cover 3 and the furnace body 2 are closed (see Figure 2 ), the spring 16 is in a state of natural extension, and when the crucible 12 moves vertically upward under the restriction of the two limiting plates 18, the spring 16 will be continuously stretched, and when the crucible 12 is completely free from the restriction of the limiting plates 18, the counterweight 17 is separated from the bottom end surface of the inner cavity of the furnace body 2 under the action of the stretched spring 16. At this time, the crucible 12 is kept in a vertical state under the action of the counterweight 17 to prevent the crucible 12 from tipping over during the process of continuing to rise after being free from the restriction of the limiting plates 18.

[0047] It should be noted that the present invention utilizes the cover unloading mechanism 5 to push the furnace cover 3 and the furnace body 2 apart in the horizontal direction, and drives the crucible 12 filled with molten liquid to rise during the separation of the furnace cover 3, and at the same time, pours out the molten liquid in the crucible 12.

[0048] Specifically, Figure 1-Figure 2 and Figure 4-Figure 5As shown, the cover unloading mechanism 5 includes two side frames 51 fixedly arranged at the top end of the outer side of the heat preservation cover 4 and guide posts 53 fixedly arranged at the outer side of the furnace cover 3 and corresponding to the side frames 51. The two side frames 51 are penetrated with a J-shaped guide groove 52, wherein the axial section of the guide post 53 and the axial section of the J-shaped guide groove 52 are both set as a flat T-shaped structure, which can ensure the stability of the movement trajectory of the furnace cover 3. The opposite ends of the two guide posts 53 are movably penetrated in the corresponding J-shaped guide groove 52. The ends of the tops of the two side frames 51 away from the furnace cover 3 are fixedly provided with limiting frames 511, wherein the limiting frames 511 are installed at the inflection point position of the corresponding J-shaped guide groove 52, and are used to guide the furnace cover 3 in translation to swing, and a receiving trough 510 is fixedly installed between the opposite sides of the two side frames 51.

[0049] The cover unloading mechanism 5 also includes a bracket 54 fixed on the outer side of the heat preservation cover 4 at the position corresponding to the side frame 51. The bracket 54 is arranged in an inclined manner. An embedding groove 55 is provided on the outer side of the bracket 54. A ball seat 56 is rotatably embedded in the embedding groove 55. A cylinder 57 is fixedly installed on the outer side of the ball seat 56. The arrangement of the ball seat 56 enables the fixed end of the cylinder 57 to swing to a certain extent during the process of pushing the furnace cover 3 to open in translation, thereby ensuring the smooth progress of the process of pushing the cover (i.e. pushing the furnace cover 3). The telescopic end of the cylinder 57 is fixedly connected to the end of the cylinder 57. There is a ring block 58 movably sleeved on the outside of the corresponding guide column 53, and two limit rings disposed on both sides of the corresponding ring block 58 are fixedly sleeved on the outside of the guide column 53. A transition platform 19 arranged in an inclined manner is also fixed on the top of one of the side frames 51. The bottom of the outer side of the low end of the transition platform 19 fits with the outer top surface of the furnace cover 3, and the existence of the transition platform 19 will not affect the crucible 12 entering and exiting the furnace body. In addition, the power mechanism for moving the garbage-pushing furnace cover 3 adopts a double-position design to ensure that the furnace cover 3 moves stably during the garbage-pushing process.

[0050] It should be noted that two notches corresponding to the L-shaped connecting rods can be opened on the side of the outer side of the furnace cover 3 away from the direction of opening the furnace cover 3, so that the L-shaped connecting rod 15 can be transformed into a horizontal state during the process of the furnace cover 3 being translated and opened. At the same time, a blocking block adapted to the notch is arranged on the top of the furnace body 32, wherein, in the process of opening the cover to pour out the molten liquid after the smelting is completed, the corresponding guide pillars 53 are synchronously pushed by two cylinders 157 to move along the J-shaped guide groove 52. When the guide pillars 53 move in the horizontal section of the J-shaped guide groove 52, the movement state of the crucible 12 is as follows: first, as the furnace cover 3 is translated and opened, the crucible 12 is limited by the two limiting plates 18 and the two L-shaped connecting rods 15, so that the furnace cover 3 will pull the two L-shaped connecting rods 15 to tilt when it moves, and at the same time, the crucible 12 carrying the molten liquid is pulled to move vertically upward under the restriction of the limiting plates 18, and the spring 16 is stretched;

[0051] Secondly, when the crucible 12 is completely free from the restriction of the restriction plate 18 during its vertical upward movement, the counterweight 17 is separated from the bottom end surface of the inner cavity of the furnace body 2 under the action of the stretched spring 16, and the furnace cover 3 is completely free from the sealing state of the furnace body 2. At this time, the crucible 12 is kept in a vertical state under the action of the counterweight 17 to prevent the crucible 12 from tipping over during the process of continuing to rise after being free from the restriction of the restriction plate 18. As the furnace cover 3 continues to translate, the L-shaped connecting rod 15 continues to change from an inclined state to a horizontal state, and at the same time, the crucible 12 is pulled closer to the edge of the furnace body 2. When the furnace cover 3 is about to enter the range of the restriction frame 511, the L-shaped connecting rod 15 is changed to a horizontal state, and the crucible 12 also moves to a position where its outer side is close to the inner edge of the furnace body 2. At this time, the arc section of the lower end of the crucible 12 is still inside the furnace body. During this process, the crucible 12 is always kept facing upward under the action of the counterweight 17.

[0052] Then, as the furnace cover 3 continues to move and open along the J-shaped guide groove 52, the furnace cover 3 will gradually deflect downward under the guidance of the limiting frame 511. During this process, the L-shaped connecting rod 15 that deflects downward synchronously will, under the restriction of the upper end of the furnace body, make the crucible 12 continue to move upward, and at the same time, continue to approach the inner edge of the furnace body 2. When the outer side of the crucible 12 contacts the inner side of the furnace body 2, the bottom end of the crucible 12 inside the furnace body 2 will be blocked. At this time, as the furnace cover 3 continues to move along the J-shaped guide groove 52, the crucible 12 will swing around the seat block 13 as the central axis under the restriction of the furnace body 2, that is, the open end of the crucible 12 will tilt toward the direction of the receiving trough 510, so that the molten liquid inside the crucible 12 is poured into the receiving trough 510.

[0053] When the molten metal is poured, the cylinder 57 is controlled to drive the furnace cover 3 to return. During this period, the tilted crucible 12 will gradually change to a state where the opening is facing upward under the action of the counterweight block 17, and then gradually fall between the two limiting plates 18 in the process of falling back into the furnace body 2, and continue to add materials to the crucible 12 for the next round of smelting.

[0054] Specifically, Figure 2 and Figure 6-Figure 7 As shown, a melt processing assembly 59 is provided between the receiving trough 510 and the side frame 51. The melt processing assembly 59 includes an arc filter screen fixed inside the receiving trough 510 and an arc channel 591 located above the arc filter screen. One end of the arc channel 591 passes through the receiving trough 510. A slag scraper frame 592 is slidably installed inside the arc channel 591.

[0055] The slag-removing frame 592 is composed of two parallel straight bars and two arc plates fixed between the two straight bars, and the arc surface sides of the two arc plates are in contact with the inner side of the arc filter screen. When the slag-removing frame 592 is completely embedded in the arc channel 591, the two arc plates and the two straight bars form a filter bearing area just above the arc filter screen in the receiving trough 510, so that the poured molten liquid can be filtered by the arc filter screen. Tooth grooves are provided on the tops of the two straight bars.

[0056] The melt processing component 59 also includes an ear plate 1 593 and two ear plates 2 594 fixed on the outside of the material receiving trough 510, and a shaft rod 595 is installed between the two ear plates 2 594 in a through-type rotational manner. A driving motor 1 is fixedly installed on one side of the ear plate 1 593, and a gear 3 598 is fixedly connected to the end of the output shaft of the driving motor 1. A gear 1 596 meshing with the gear 3 598 is fixedly sleeved on the middle part of the outer side of the shaft rod 595, and gear 2 597 meshing with the corresponding tooth grooves are fixedly sleeved on both ends of the outer side of the shaft rod 595.

[0057] It should be noted that in the process of pouring the molten liquid inside the crucible 12 into the receiving trough 510, the solid particles suspended in the molten liquid will be filtered out through the arc filter screen, and the molten liquid passing through the arc filter screen will fall into the receiving ladle below the receiving trough 510. When the poured molten liquid is filtered, the drive motor 1 will be started to drive the gear 3 598 to rotate, and drive the shaft 595 to rotate, and the gear 2 597 rotating with the shaft 595 will drive the corresponding straight bar to move in the direction of leaving the arc groove 591, and drive the arc plate to scrape the residue intercepted on the arc filter screen away from the arc filter screen, and then place a collection box at the port position of the arc groove 591 to collect the residue for subsequent reuse.

[0058] Specifically, Figure 4 and Fig.13As shown, a stirring mechanism 6 for continuously stirring the materials during the smelting process is fixedly installed on the top of the furnace cover 3, and the stirring mechanism 6 includes a cover tube 61 fixed on the top of the furnace cover 3. A through hole is opened at the position of the top of the furnace cover 3 corresponding to the cover tube 61, and a cylinder 2 62 is fixedly installed on the top of the cover tube 61. The telescopic end of the cylinder 2 62 extends to one end of the cover tube 61 and is fixedly connected to a heat insulation board 64. A driving motor 2 is fixedly installed on the top of the heat insulation board 64. The setting of the heat insulation board 64 can be used to prevent the heat during the smelting process from affecting the driving motor The operation of the second machine, the output shaft end of the driving motor 2 is fixedly connected with a stirring head 65, which can promote the heat and mass transfer process in the furnace body 2, improve the dynamic conditions of smelting, thereby improving the uniformity and melting rate of the melt, and promoting the smelting process. A notch 63 is provided at the upper end of the outer side of the cover tube 61 to accelerate the dissipation of heat generated during the operation of the driving motor 2, wherein the stirring head 65 is composed of a disc body and a plurality of rod bodies fixed at the bottom of the disc body, which can make it easier for the stirring head 65 to be inserted into the material inside the crucible 12.

[0059] It should be noted that after each stirring is completed, the cylinder 2 62 can be controlled to completely retract the stirring head 65 into the inside of the cover tube 61 to ensure that the process of sliding the furnace cover 3 open is not obstructed. In the process of melting the target material added to the crucible 12, the cylinder 2 62 is used to push the insulation board 64 downward to allow the stirring head 65 to be inserted into the melt in the crucible 12. At this time, the insulation board 64 just blocks the through hole on the furnace cover 3, and then starting the drive motor 2 can drive the stirring head 65 to perform the stirring action.

[0060] Specifically, Figure 2 and Figure 8-Figure 9 As shown, the feeding mechanism 7 is fixed to two supports 76 on the top of the base 1, and a feeding cylinder 71 is arranged on the top of the support 76 in an inclined manner. A ring cover 1 74 and a ring cover 2 75 are fixedly sleeved on the outer side of the feeding cylinder 71, and the two supports 76 are fixedly connected to the corresponding ring cover 1 74 and the ring cover 2 75 respectively;

[0061] The feeding mechanism 7 also includes a discharge pipe 73 and a feed pipe 72 respectively fixed at the top and bottom ends of the outer side of the feed barrel 71. A drive motor 3 is fixedly installed at the high end of the feed barrel 71. The output shaft of the drive motor 3 extends to one end inside the feed barrel 71 and is fixedly connected to a feed screw 77. The spiral blades of the feed screw 77 are arranged in a mesh structure, and a hole plate 78 is fixedly sleeved on the outer side of the low end of the feed screw 77. The horizontal plane where the discharge end of the feed pipe 72 is located is higher than the horizontal plane where the hole plate 78 is located, so as to prevent the material entering the inside of the feed barrel 71 from leaking out from the lower end of the feed barrel 71.

[0062] It should be noted that, in the process of loading materials into the furnace body 2, the feed screw 77 is driven to rotate by driving motor three, so that the material entering the feed tube 71 from the feed pipe 72 is continuously transported upward, and discharged from the discharge pipe 73 at the upper end of the feed tube 71 to the transition platform 19, and then enters the crucible 12 in the furnace body 3 through the inclined transition platform 19. After the molten liquid completed in the previous round of smelting is poured out, the next round of loading is started after the crucible 12 falls back to the position between the two limiting plates 18. This can avoid the shaking of the crucible 12 during the loading process, which may cause some materials to fail to fall into the crucible 12.

[0063] Example 2

[0064] Refer to the instruction manual Figure 1 , Figure 4 and Figure 8-Figure 12 In an aluminum alloy ingot processing furnace according to an embodiment of the present invention, a filtering mechanism 8 is installed on the top of the base 1, and the filtering mechanism 8 includes a water tank 81 fixed on the top of the base 1, and the bottom end of the feeding cylinder 71 extends into the water tank 81. A filter disc 82 is arranged inside the water tank 81, and the filter disc 82 is composed of a fixed filter plate 821 fixed inside the water tank 81 and a movable filter plate 822 movably plugged into the water tank 81.

[0065] A waste heat utilization mechanism 9 is provided between the furnace body 2 and the feeding tube 71. The waste heat utilization mechanism 9 includes a ring cover 94 fixedly sleeved on the outside of the discharge pipe 73 and a hot water pipe 91 and a hot air pipe 92 wound around the outside of the furnace body 2. The hot water pipe 91 and the hot air pipe 92 wound around the outside of the furnace body 2 are open (see Fig.10 and Fig.11 ) structure, which can make the water and air introduced absorb the heat from the outside of the furnace body 2 better, thereby increasing the heating speed of the water and air. A return air hole 95 is provided through the position of the outside of the discharge pipe 73 corresponding to the inside of the ring cover 3 94, and a through hole 96 is provided at the position of the outside of the feeding cylinder 71 corresponding to the inside of the ring cover 1 74 and the ring cover 2 75, and a high-pressure nozzle 97 is installed inside each through hole 96 on the inside of the ring cover 2 75;

[0066] The two ends of the hot water pipe 91 are respectively connected to the water tank 81 and the ring cover 2 75, and a circulating water pump is installed at one end of the hot water pipe 91 close to the water tank 81. The two ends of the hot air pipe 92 are respectively connected to the ring cover 1 74 and the ring cover 3 94, and a gas circulating pump is installed at one end of the hot air pipe 92 close to the ring cover 3 94.

[0067] The waste heat utilization mechanism 9 also includes a fixed seat fixed on the outside of the heat preservation cover 4, on which an exhaust pipe 93 is fixedly installed. One end of the exhaust pipe 93 is movably connected to the outlet end of the exhaust pipe 11, and the other end of the exhaust pipe 93 is connected to the heat exchanger to replace the heat in the high-temperature exhaust gas for other places where heat energy is needed. The movable connection between the exhaust pipe 93 and the exhaust pipe 11 can ensure that the opening process of the furnace cover 3 will not be hindered. At the same time, the exhaust gas can be smoothly guided to be discharged during the process of closing the furnace cover 3 for smelting.

[0068] It should be noted that in the process of making full use of the heat generated during smelting, the water in the water tank 81 is pumped into the hot water pipe 91 through a circulating water pump, and after absorbing heat in the area where the furnace body 2 is located and becoming hot water, it is transported to the inside of the ring cover 75, and then sprayed through the high-pressure nozzle 97 in the area to the surface of the material inside the feeding cylinder 71 to wash away the impurities (including but not limited to particulate matter and dust) and grease remaining on the surface of the material, and then leaked into the water tank 81 through the mesh on the feeding screw 77 and the holes on the orifice plate 78, and after being filtered by the filter disc 82, it is recycled and reused, and by using hot water to rinse the surface of the material, the material can also be preheated;

[0069] At the same time, the gas circulation pump will also suck air from the return air hole 95 at the ring cover three 94, allowing the air to enter the hot air pipe 92, and after passing through the area where the furnace body 2 is located, it absorbs heat and becomes hot air, which is then transported to the inside of the ring cover one 74, and then passes through the perforations 96 in the area and sprayed to the surface of the material inside the feeding barrel 71. On the one hand, it can achieve drying of the residual moisture on the surface of the material after washing, and on the other hand, it can achieve further preheating of the material. The air entering the feeding barrel 71 will finally be sucked back into the hot air pipe 92 for circulation under the action of the gas circulation pump;

[0070] In addition, after the materials being transported are rinsed and preheated with hot water, the sewage flowing back into the water tank 81 will be processed by the filter disc 82, so that the particulate impurities in the sewage generated by the flushing will be intercepted by the fixed filter plate 821, and the grease in the sewage or the dust passing through the fixed filter plate 821 will be absorbed by the filler inside the sedimentation tank on the movable filter plate 822, ensuring the cleanliness of the circulating flushing water.
