[0028] Embodiment 1

[0029] An acceleration smelting device for non-ferrous metal smelting, referring to Figures 1-6 , includes a support frame 1, a smelting furnace 2, a partition board 3, a decomposition mechanism 4 and a sieving mechanism 5. The smelting furnace 2 is installed on the upper part of the support frame 1, the partition board 3 is clamped at the lower part of the smelting furnace 2, the decomposition mechanism 4 is arranged at the upper part of the smelting furnace 2, the decomposition mechanism 4 is used for crushing non-ferrous metals, and the sieving mechanism 5 is arranged on the decomposition mechanism 4, and the sieving mechanism 5 is used for sieving non-ferrous metals. Referring to Figure 3 , the decomposition mechanism 4 includes a blanking frame 41, a blanking pipe 42, a motor 43, a first rotating shaft 44, a second rotating shaft 45, opposed gears 46 and a cutting wheel 47. The blanking frame 41 is connected to the upper part of the smelting furnace 2, the upper side of the left wall of the blanking frame 41 is connected to the blanking pipe 42, the motor 43 is installed on the lower side of the right wall of the blanking frame 41, the front and rear sides of the middle part of the blanking frame 41 are both rotatably connected to the second rotating shaft 45, the right part of the second rotating shaft 45 on the front side is slidably connected to the first rotating shaft 44, the first rotating shaft 44 is clamped to the output shaft of the motor 43, the right parts of the second rotating shafts 45 are both connected to the opposed gears 46, the two opposed gears 46 are meshed with each other, and the second rotating shafts 45 are both connected to the cutting wheels 47, and the cutting wheels 47 are used for crushing non-ferrous metals. Referring to Figures 4-6, the screening mechanism 5 includes a cam 51, a top plate 52, a fixing plate 53, a sieve plate 54, a first linear spring 55 and a placement plate 56. The left part of the front second rotating shaft 45 is connected to the cam 51. The lower part inside the blanking frame 41 is connected to the fixing plate 53. The placement plate 56 is slidably connected to the fixing plate 53. The left side of the top of the placement plate 56 is connected to the top plate 52. A first through hole 57 is opened in the middle of the left side of the blanking frame 41. The top plate 52 passes through the first through hole 57. The cam 51 rotates and contacts the upper part of the top plate 52. The sieve plate 54 is placed on the placement plate 56. The sieve plate 54 is used for screening non-ferrous metals. Four first linear springs 55 are connected between the placement plate 56 and the fixing plate 53. The first linear springs 55 are sleeved on the placement plate 56. A taking port is opened on the lower side of the left wall of the blanking frame 41. When in use, people replace the sieve plate 54 through the taking port. In this way, the sieve plate 54 with different hole diameters can be replaced according to the actual smelting requirements. After replacement, an appropriate amount of non-ferrous metals of different sizes are added into the blanking frame 41 through the blanking pipe 42. The non-ferrous metals fall on the cutting wheel 47. Then, the motor 43 is started. The output shaft of the motor 43 rotates to drive the first rotating shaft 44 to rotate, and then drives the front second rotating shaft 45 to rotate. The front second rotating shaft 45 drives the front opposed gear 46 and the front cutting wheel 47 to rotate. The front opposed gear 46 drives the rear opposed gear 46 to rotate, and then drives the rear second rotating shaft 45 and the rear cutting wheel 47 to rotate, so that the cutting wheel 47 crushes the non-ferrous metals, accelerating the smelting of the non-ferrous metals. After crushing, the motor 43 is turned off. The non-ferrous metals fall downward onto the sieve plate 54. When the front second rotating shaft 45 rotates, it drives the cam 51 to rotate. When the cam 51 contacts the top plate 52, it pushes the top plate 52 upward. The top plate 52 drives the placement plate 56 to move upward. The first linear spring 55 is compressed. The placement plate 56 drives the sieve plate 54 to move upward. When the cam 51 rotates and separates from the top plate 52, it drives the placement plate 56, the top plate 52 and the sieve plate 54 to move downward and reset under the action of the reset of the first linear spring 55. In this way, the cam 51 rotates and repeatedly contacts and separates from the top plate 52, causing the sieve plate 54 to vibrate up and down to screen the non-ferrous metals, so that the non-ferrous metals with relatively consistent sizes fall downward into the smelting furnace 2. People take out the sieve plate 54, collect the non-ferrous metals remaining on the sieve plate 54 and smelt them subsequently. The smelting furnace 2 is started, so that the smelting furnace 2 smelts the non-ferrous metals with relatively consistent sizes. After smelting, the smelting furnace 2 is turned off, and the blocking plate 3 is removed, so that the smelted non-ferrous metals flow downward.

The telescopic rod of the cylinder 62 extends to drive the pressing plate 63 to move downward. The pressing plate 63 contacts the non-ferrous metal and then squeezes the non-ferrous metal downward, accelerating the crushing of the non-ferrous metal and improving work efficiency. When the pressing plate 63 approaches the cutting wheel 47, control the telescopic rod of the cylinder 62 to contract to drive the pressing plate 63 to move upward, and then turn off the cylinder 62.

A second linear spring 74 is connected between the left side of the first rotating shaft 44 and the right part of the front second rotating shaft 45. The second linear spring 74 is located in the right inner part of the second rotating shaft 45. When the pressing plate 63 moves downward, it drives the limiting plate 71 to move downward. When the upper part of the limiting plate 71 contacts the limiting disc 73, it squeezes the limiting disc 73 to the left. The limiting disc 73 drives the first rotating shaft 44 to move to the left and separate from the output shaft of the motor 43. The second linear spring 74 is compressed, so that the cutting wheel 47 stops rotating, preventing the cutting wheel 47 from contacting the pressing plate 63 and damaging the pressing plate 63. When the pressing plate 63 moves upward, it drives the limiting plate 71 to move upward. The upper part of the limiting plate 71 separates from the limiting disc 73. Then, under the action of the reset of the second linear spring 74, the limiting disc 73 and the first rotating shaft 44 move to the right, and the first rotating shaft 44 is stuck into the output shaft of the motor 43.

Non-ferrous metals with relatively consistent sizes fall downward onto the partition plate 81. After the non-ferrous metals are smelted, people manually rotate the rotating rod 84, the torsion spring 85 deforms, the rotating rod 84 drives the isolation ball 82 to rotate, so that the third through hole 83 communicates with the smelting furnace 2, and the smelted non-ferrous metals fall downward into the lower part of the smelting furnace 2 through the third through hole 83. Then, the rotating rod 84 is released, and further, under the action of the reset of the torsion spring 85, the rotating rod 84 and the isolation ball 82 are driven to reverse and reset, and non-ferrous metals with relatively consistent sizes can continue to fall into the upper part of the smelting furnace 2, so as to realize continuous smelting of non-ferrous metals and save time.
