Description

Technical Field

[0002] The high-frequency induction aluminum alloy melting furnace for recycling automotive aluminum scrap is an industrial furnace specially designed for melting aluminum alloy materials, especially aluminum scrap recycled from the automotive industry. This furnace uses high-frequency induction technology to heat and melt aluminum alloys, featuring high energy efficiency, rapid melting, and precise control. Automotive aluminum scrap mainly comes from aluminum parts from scrapped vehicles, such as wheels, engine cylinder blocks and heads, crankcases, intake manifolds, gearboxes, oil pumps, etc. Most of these parts are made of cast aluminum alloy.

[0003] Before entering the aluminum alloy melting furnace for processing, automotive scrap aluminum usually needs to undergo certain pretreatment, including dehydration. This is because the scrap aluminum may contain moisture during the recycling process. This moisture will be converted into gas during the melting process, which may cause pressure changes in the melting furnace, increase gas content, and even cause safety problems such as explosion. The dehydration process helps to reduce these risks and ensure the smooth progress of the melting process.

[0004] When dehydrating automobile scrap aluminum, the parts of the automobile scrap aluminum need to be placed separately inside the preheating chamber. The existing device directly places the automobile scrap aluminum in a pile inside the preheating chamber. During dehydration, the parts of the automobile scrap aluminum fit together, resulting in incomplete dehydration and slow dehydration efficiency, which reduces the preheating quality of the automobile scrap aluminum. Therefore, to address the above problems, a high-frequency induction aluminum alloy melting furnace based on the recycling of automobile scrap aluminum and a control method thereof are proposed.

The feed port 3 and the support plate 5 are in the same vertical plane.

[0045] As a further implementation of this solution, the top view shape of the mounting support plate 41 is a "concave" shape, the opening shape of the rail groove 47 is a rectangular body, the rail groove 47 is opened on the inner side of the left end and the inner side of the right end of the mounting support plate 41, the left and right ends of the half-grooved cylinder 43 are fixedly connected to the limiting slider, the half-grooved cylinder 43 is shaped like a slotted cylinder, and a through hole is opened on the inner side of the lower end of the half-grooved cylinder 43.

The sealing ring 44 is shaped like a circular ring, and the inner side of the sealing ring 44 is fitted with the outer side of the front end of the metal insulation cylinder 81 through a sealing ring to achieve the effect of recycling hot exhaust gas. The sealing ring 44 and the half-grooved cylinder 43 are sealed by a sealing ring to prevent hot exhaust gas from overflowing, which is convenient for disassembly of the sealing ring 44 and replacement and maintenance of the filter plate 45.

[0046] As a further implementation of this solution, the number of the bracket plates 5 is two, and a rotating hole is opened on the inner side of the bracket plate 5. The main shaft of the first servo motor 6 rotates inside the rotating hole of the bracket plate 5. The left end of the limiting fixing ring 71 is rotatably connected to the left end bracket plate 5 through a roller, thereby reducing the labor of the staff and preventing the preheated automobile scrap aluminum from scalding the staff.

[0047] As a further implementation of this solution, the limiting fixing ring 71 is in the shape of a slotted circular ring, and the number of the ring track grooves 73 is two. The ring track grooves 73 are located at the front and rear ends of the movable ring groove 72. The ring shaft ring 83 is rotatably connected to the inner side of the ring track groove 73. A through hole is provided at the lower end of the limiting fixing ring 71. The limiting fixing ring 71 is connected to the interior of the empty solid box 74 through the through hole. The gear 76 is inside the through hole of the limiting fixing ring 71. The outer side of the gear 76 meshes with the outer side of the ring gear 84. The ring gear 84 is installed inside the movable ring groove 72, which can produce a rolling effect on the internal automotive scrap aluminum, and can effectively prevent the automotive scrap aluminum from sticking to each other or sticking to the inner side of the rubber sleeve 87, so that the hot exhaust gas cannot contact the automotive scrap aluminum, thereby ensuring the uniformity and efficiency of the dehydration of the automotive scrap aluminum, and does not affect the subsequent processing;

[0048] As a further implementation scheme of this scheme, the metal insulation tube 81 is shaped like a hollow cylinder, and an air outlet is provided at the rear end of the metal insulation tube 81. The metal shell 86 and the rubber sleeve 87 are both shaped like hollow cylinders, and multiple through holes 88 are provided inside the metal shell 86 and the rubber sleeve 87 to prevent deformation caused by collision of automobile scrap aluminum with the multiple through holes 88, to prevent contact between the metal shell 86 and the metal insulation tube 81, and to improve the service life of the device.

[0049] Working process: when it is necessary to dehydrate the scrap aluminum of automobiles inside the multi-through hole 88, the device is powered on by an external power supply during use, and the second servo motor 75 is started. The main shaft of the second servo motor 75 rotates to drive the gear 76 fixedly connected to the end of the main shaft to rotate. The gear 76 rotates inside the lower end of the limiting fixing ring 71. When the gear 76 rotates, it drives the outer meshing ring gear 84 to rotate. The ring gear 84 drives the metal insulation cylinder 81 fixedly connected on the inner side to rotate. The metal insulation cylinder 81 is rotatably connected to the limiting fixing ring 71 through the ring shaft ring 83. The ring shaft ring 83 is rotatably connected to the inner side of the ring rail groove 73 opened in the limiting fixing ring 71, which plays a role in the rotation of the metal insulation cylinder 81. The ring shaft ring 83 plays a role of limiting the position, and at the same time, the ring shaft ring 83 plays a role of supporting the limiting fixed ring 71, preventing the movable ring groove 72 opened on the inner side of the limiting fixed ring 71 from fitting and rubbing against the outer side of the gear ring 84. The rotation of the metal insulation cylinder 81 drives the spring 85 fixed on the inner side to rotate, and the spring 85 drives the metal shell 86 and the rubber sleeve 87 to rotate. When the rubber sleeve 87 rotates, it can produce a rolling effect on the scrap aluminum inside, which can effectively prevent the scrap aluminum from fitting against each other or the scrap aluminum from fitting against the inner side of the rubber sleeve 87, resulting in that the hot exhaust gas cannot contact the scrap aluminum, thereby ensuring the uniformity and efficiency of the dehydration of the scrap aluminum, and does not affect the subsequent processing;

[0050] When recycling the hot exhaust gas inside the aluminum alloy melting furnace body 1, before dehydration, the hydraulic rod 42 is started, and the hydraulic rod 42 drives the half-grooved drum 43 to move. The half-grooved drum 43 is slidably connected to the inner side of the rail groove 47 opened on the mounting support plate 41 through the limit slider, which plays a role in limiting and supporting the movement of the half-grooved drum 43. The half-grooved drum 43 drives the sealing ring 44 to move. When the sealing ring fixed on the inner side of the sealing ring 44 fits with the outer side of the front end of the limit fixing ring 71, the hot exhaust gas inside the aluminum alloy melting furnace body 1 enters the exhaust gas outlet 2 from the inside. The hot exhaust gas passes through the hose 46 and enters the interior of the half-grooved drum 43 and the front end of the filter plate 45. The hot exhaust gas passes through the filter plate 45, which filters impurities in the hot exhaust gas. The filtered hot exhaust gas passes through the sealing collar 44 and enters the interior of the limiting fixing ring 71, thereby achieving the effect of recycling the hot exhaust gas. The sealing collar 44 and the half-grooved drum 43 are sealed by a sealing ring. At the same time, the sealing collar 44 and the half-grooved drum 43 are fixed by bolts, which facilitates the removal of the sealing collar 44 and the replacement and maintenance of the filter plate 45.

[0051] When the scrap aluminum is rotated, it continuously collides with the rubber sleeve 87, which acts as a buffer for the scrap aluminum. At the same time, the multiple through holes 88 can increase the contact friction with the scrap aluminum. The metal shell 86 is a hard metal, which prevents the scrap aluminum from deforming when colliding with the multiple through holes 88. After the collision with the scrap aluminum, the metal shell 86 will be displaced. The metal shell 86 squeezes or stretches part of the spring 85, and the spring 85 acts as a buffer for the metal shell 86, preventing the metal shell 86 from contacting the metal insulation tube 81, thereby increasing the service life of the device. The rubber sleeve 87 and the multiple through holes 88 inside the metal shell 86 facilitate the communication between the gas inside the metal insulation tube 81 and the gas inside the multiple through holes 88. The constant pressure hole 82 facilitates the discharge of the utilized hot exhaust gas.

[0052] When unloading the automobile scrap aluminum inside the multi-through hole 88, the hydraulic rod 42 is started to disengage the sealing ring 44 from the limiting fixing ring 71 and move away, and the first servo motor 6 is started. The first servo motor 6 drives the limiting fixing ring 71 to rotate, and the limiting fixing ring 71 drives the metal insulation tube 81 to rotate through the ring shaft ring 83. When the metal insulation tube 81 rotates ninety degrees, the electric valve inside the feed port 3 is opened. At this time, the automobile scrap aluminum inside the multi-through hole 88 falls into the interior of the aluminum alloy melting furnace body 1, thereby reducing the labor of the staff and preventing the preheated automobile scrap aluminum from scalding the staff.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

10. The control method of a high-frequency induction aluminum alloy melting furnace for recycling automobile aluminum scrap according to any one of claims 1 to 9, characterized in that: S1: When it is necessary to dehydrate the automobile scrap aluminum inside the multi-through hole (88), the main shaft of the second servo motor (75) rotates to drive the gear (76) fixedly connected to the end of the main shaft to rotate, and the gear (76) rotates inside the lower end of the limit fixing ring (71). When the gear (76) rotates, it drives the outer meshing ring gear (84) to rotate, and the ring gear (84) drives the metal insulation tube (81) fixedly connected inside to rotate, and the metal insulation tube (81) is rotationally connected to the limit fixing ring (71) through the ring shaft ring (83), and the ring shaft ring (83) is rotationally connected to the inner side of the ring track groove (73) opened by the limit fixing ring (71). The rotation of the metal insulation tube (81) drives the spring (85) fixedly connected inside to rotate, and the spring (85) drives the metal shell (86) and the rubber sleeve (87) to rotate; S2: When recycling the hot exhaust gas inside the aluminum alloy melting furnace body (1), before dehydration, the hydraulic rod (42) drives the half-grooved drum (43) to move, and the half-grooved drum (43) is slidably connected to the inner side of the rail groove (47) opened by the mounting support plate (41) through the limit slider. The half-grooved drum (43) drives the sealing ring (44) to move. When the sealing ring fixed on the inner side of the sealing ring (44) fits with the outer side of the front end of the limit fixing ring (71), the hot exhaust gas inside the aluminum alloy melting furnace body (1) enters the inside of the hose (46) from the inside of the exhaust gas outlet (2), and enters the inside of the half-grooved drum (43) and the front end of the filter plate (45) from the inside of the hose (46). The hot exhaust gas passes through the filter plate (45), and the sealing ring (44) and the half-grooved drum (43) are sealed by the sealing ring; S3: When the scrap aluminum is rotated, the scrap aluminum continuously collides with the rubber sleeve (87).
