Description

Technical Field

[0001] The utility model relates to the field of aluminum casting and rolling coil production, in particular to an anti-blocking aluminum ingot smelting device. Background Art

[0002] The rolling of aluminum cast coils generally includes the following process: aluminum ingots pass through a melting furnace and a holding furnace to form aluminum liquid, which is then degassed by a degassing device and filtered by a filtration device before entering the head box. From the head box, it enters the aluminum casting and rolling mill through a casting nozzle to form aluminum cast rolled plates, which are finally sheared and coiled to form aluminum cast rolled coils.

[0003] A search of the patent document with publication number CN217210313U discloses "a device for melting aluminum ingots for aluminum cast and rolled coil production. During operation, the device places the aluminum ingot into a crushing box from a loading port, activates a drive motor and a vibration motor, and the output shaft of the drive motor rotates, driving a first crushing rod. Simultaneously, the second gear, meshing with the first gear, drives the second crushing rod to rotate, thereby causing the crushing blades on the two crushing rods to crush the aluminum ingot. The crushed aluminum ingot fragments fall onto a porous plate below. Smaller aluminum ingot fragments, vibrated by the vibration of the vibration motor, fall through the holes in the porous plate to the discharge port of the crushing box, while larger aluminum ingot fragments slide along the porous plate to the first through-hole of the crushing box."

[0004] When the above device is in operation, although the rotation of the crushing rod and the crushing knife can crush the aluminum ingot to be smelted, thereby improving the smelting efficiency of the aluminum ingot fragments, the shape and size of the aluminum ingot fragments after crushing are difficult to determine. In this way, after some aluminum ingot fragments are stuck in the sieve holes of the porous plate, the aluminum ingot fragments continue to fall, which is likely to cause the stuck aluminum ingot fragments to be subjected to the impact force of the fall, causing them to be stuck tighter, thereby easily causing the porous plate to be blocked and affecting the subsequent smelting efficiency.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-6 As shown, an anti-clogging aluminum ingot smelting device includes a base plate 1, a crushing frame 11 is installed on the upper end of the base plate 1, a smelting mechanism is installed in the middle position of the upper end of the base plate 1, a crushing mechanism is installed inside the crushing frame 11, and also includes a screening mechanism.

[0028] A feed hopper 12 is fixed to the upper end of the crushing frame 11, and a slope is provided at the through hole at the bottom of the crushing frame 11. A discharge port 13 is fixed to one end of the crushing frame 11, and the discharge port 13 corresponds to the position of the vibration frame 31; the aluminum ingot to be processed can be poured into the crushing frame 11 through the feed hopper 12 for crushing.

[0029] The crushing mechanism includes two rotating shafts 2, which are rotatably connected to the inner part of the crushing frame 11 near the upper end. A first motor 21 is installed at the input end of one of the rotating shafts 2. Gears 22 are fixed to the rear ends of the two rotating shafts 2, and the two gears 22 are engaged with each other. A crushing roller 23 is fixed to the outer ring of the rotating shaft 2; through the mutual engagement of the two gears 22, when the first motor 21 drives one of the rotating shafts 2 to rotate, the two crushing rollers 23 can be rotated, thereby enabling the aluminum ingot to be crushed.

[0030] The screening mechanism includes four fixed rods 3, which are fixed to the inner wall of the crushing frame 11. A vibration frame 31 is slidably connected between the four fixed rods 3. The four corners of the upper end of the vibration frame 31 are fixed with first springs 32, and the four first springs 32 are respectively located at the outer rings of the four fixed rods 3. A sieve plate 33 is fixed in the middle of the vibration frame 31. The vibration frame 31 and the sieve plate 33 are arranged in an inclined manner. A vibration motor 34 is installed at the lower end of one side of the sieve plate 33, and a drive motor 35 is installed at the lower end of the other side of the sieve plate 33. The drive motor 35 is a double-output shaft motor. A swivel 36 is fixed on the two output shafts of the drive motor 35. A lower end of the swivel 36 is fixed with a lower extension block 37. The lower end of the lower extension block 37 is fixed with a second spring 38. The lower end of the second spring 38 is fixed with a hammer block 39, and the outer ring of the hammer block 39 is provided with a rubber Layer; after starting the vibration motor 34 and the drive motor 35, through the sliding connection between the vibration frame 31 and the fixed rod 3 and the elasticity of the first spring 32, when the vibration motor 34 is started, the vibration frame 31 and the sieve plate 33 can vibrate slightly, which not only speeds up the screening efficiency, but also shakes out the aluminum ingot fragments that are not clamped in the sieve holes of the sieve plate 33. By starting the drive motor 35, the rotating ring 36 can be rotated, and the hammer block 39 can be rotated to knock the sieve plate 33, so that some clamped aluminum ingot fragments can be discharged. In this way, the aluminum ingot fragments can be prevented from blocking the sieve holes of the sieve plate 33 and causing an impact, and through the elasticity of the second spring 38, when the hammer block 39 knocks on the sieve plate 33, the second spring 38 can be bent, thereby avoiding affecting the rotation of the rotating ring 36 driven by the drive motor 35.

[0031] The smelting mechanism includes a furnace 4, which is fixed in the middle position of the upper end of the base plate 1. Two supporting bars 41 are fixed to the upper end of the furnace 4. A cover plate 42 is slidably connected between the two supporting bars 41. A groove is provided at one end of the cover plate 42. A liquid outlet pipe 43 is installed at the front end of the furnace 4. A valve body is installed in the middle of the liquid outlet pipe 43. An exhaust pipe 44 is fixed at one end of the furnace 4. A supporting frame 45 is fixed to the output end of the exhaust pipe 44. A filter layer 46 is provided inside the supporting frame 45. The filter layer 46 is made of activated carbon filter cotton. Through the sliding connection between the cover plate 42 and the supporting bar 41, when the furnace 4 is smelting aluminum ingots, the cover plate 42 is pushed to cover the upper end of the furnace 4. The exhaust gas generated during the smelting process will be discharged through the exhaust pipe 44 and the supporting frame 45, and the filter layer 46 will filter the harmful substances in the exhaust gas.

[0032] Working principle: Before the device is operated, a box structure with an upper end opening is first placed at the lower end of the discharge port 13, and then the aluminum ingot to be processed is poured into the crushing frame 11 through the feed hopper 12. After the preparation work is completed, the first motor 21 is started. Through the mutual engagement of the two gears 22, when the first motor 21 drives one of the rotating shafts 2 to rotate, the two crushing rollers 23 can be rotated, so that the aluminum ingot can be crushed. The crushed aluminum ingot fragments will fall onto the screen plate 33. At this time, the vibration motor 34 and the drive motor 35 are started. Through the sliding connection between the vibration frame 31 and the fixed rod 3 and the elasticity of the first spring 32, when the vibration motor 34 is started, the vibration frame 31 and the screen plate 33 can vibrate slightly. This not only speeds up the screening efficiency, but also can shake out the aluminum ingot fragments that are not stuck in the sieve holes of the screen plate 33. By starting the drive motor 35, the swivel 36 can be rotated, which can make the hammer block 39 rotate and hit the screen plate 3 3, so that some of the clamped aluminum ingot fragments can be discharged, by doing so, it can be prevented that the aluminum ingot fragments block the sieve holes of the sieve plate 33 and cause an impact, and through the elasticity of the second spring 38, when the hammer block 39 hits the sieve plate 33, the second spring 38 can be bent, thereby preventing the driving motor 35 from driving the rotating ring 36 to rotate. After screening, the aluminum ingot fragments of appropriate size may fall into the furnace 4, while the aluminum ingot fragments of larger size may slide into the box structure at the lower end of the discharge port 13 as the sieve plate 33 tilts. After the aluminum ingots are crushed and screened, the aluminum ingot fragments of larger size in the box structure are poured into the device from the feed hopper 12 again for crushing. After the aluminum ingots are completely crushed and fall into the furnace 4, the cover plate 42 is slidably connected to the support bar 41 to push the cover plate 42 to block the feed port at the upper end of the furnace 4. Then the furnace 4 starts to smelt the aluminum ingots. The exhaust gas generated during smelting will be filtered through the filter layer 46 and then discharged.
