Description

Technical Field

[0001] The present invention relates to the technical field of lead ingot processing, in particular to a lead ingot heat treatment processing and conveying device. Background Art

[0002] Lead ingots are a raw material commonly used in the manufacture of batteries, coatings, bullets, bearing materials, welding materials, chemical lead salts, cable sheathing, caulking materials, babbitt alloys, and X-ray shielding materials. Lead ingots typically require further processing before use, such as melting in a furnace. This processing requires transporting the ingots from a warehouse to the furnace. Traditional lead ingot conveying systems directly deliver the ingots to the lead melting furnace. Due to the lack of a buffer mechanism, the ingots can splash the molten lead inside the furnace during transport, posing a safety hazard to the production process. Furthermore, the lead ingot processing furnaces are large, but the furnace openings are small, hindering accurate placement of the ingots into the furnace. During use, and after prolonged storage, the lead ingots oxidize with air, forming an oxide layer, dust, or other foreign matter. If the surface is not cleaned before smelting, the oxide layer and contaminants will directly affect the smelting quality of the ingots.

The top of the buffer spring is fixedly connected to the bottom of the buffer plate 89. Under the action of gravity, the lead ingot squeezes the buffer plate 89, and the buffer plate 89 squeezes the spring, thereby reducing the speed of the lead ingot's descent. The lead ingot falls smoothly into the smelting furnace to avoid lead splashing caused by the fall of the lead ingot, which causes a safety hazard.

[0041] The working principle of the present invention is as follows: when in use, the lead ingot is placed on the primary conveying mechanism 4, the first motor 41 is started, driving the first gear 43 to rotate, the first gear 43 tube first chain 45 drives other first gears 43 to rotate, thereby driving the first transmission rod 42 to rotate, the first transmission rod 42 drives the first conveying roller 44 to rotate, thereby driving the lead ingot to move from back to front and enter the cleaning mechanism 5, the second motor 57 is started, driving the third gear 55 to rotate, the third gear 55 drives the second gear 53 to rotate through the second chain 56, the second gear 53 and the third gear 55 synchronously drive the first rotating rod 52 and the second rotating rod 54 to rotate, thereby driving the brush 58 to rotate, and at the same time driving the lead ingot to move forward, and cleaning the lead ingot. The dust on the surface is cleaned, and the vacuum pump 510 is started to collect the cleaned dust into the collection box 59. In order to adapt to different furnace openings and facilitate the delivery of lead ingots to the smelting furnace, the two three-stage conveying mechanisms 7 are adjusted to be close to each other, and the fifth motor 95 is started to drive the driving rod 96 to rotate. The driving rod 96 drives the forward and reverse screws 97 to rotate. The forward and reverse screws 97 drive the driving blocks 98 on both sides to approach each other, thereby driving the two three-stage conveying mechanisms 7 to approach, and then drive the front ends of the secondary conveying mechanisms 6 on both sides to approach each other. After the lead ingot is cleaned in the cleaning mechanism 5, it enters between the two secondary conveying mechanisms 6 under the drive of the first conveying roller 44. The third motor 67 is started to drive the fourth gear 65 to rotate, and the third gear 55 is turned on. The third chain 66 drives the other third gear 55 to rotate, thereby driving the second transmission rod 64 to rotate, and the second transmission rod 64 drives the second conveying roller 63 to rotate, and the second conveying roller 63 and the first conveying roller 44 drive the lead ingot to continue to move forward, and under the cooperation of the secondary conveying mechanisms 6 on both sides, the lead ingot is driven to move closer to the middle, and then enters between the two tertiary conveying mechanisms 7 and enters the preheating mechanism 9. The hot air generated by the smelting of the lead ingot enters the heat exchange tube 94 through the air inlet pipe 92. The hot air moves one circle in the heat exchange tube 94 and is discharged from the air outlet pipe 93. The heat emitted by the hot air in the heat exchange tube 94 is transferred to the inside of the rectangular box 91, heating the lead ingot moving from the rectangular box 91, and preheating is performed in advance before the lead ingot is melted. As the level conveying mechanisms 7 approach each other, they drive the first side plate 81 and the second side plate 83 to approach each other, so that the first tooth plate 82 and the second tooth plate 84 approach each other, thereby limiting the position of the lead ingot to adapt to smelting furnaces with different furnace openings. The fourth motor 72 is started, driving the fifth gear 73 to rotate, the fifth gear 73 drives the third transmission rod 76 to rotate, and the third transmission rod 76 drives the fourth conveying roller 77 to rotate, thereby driving the lead ingot to move in the rectangular box 91, and then discharged from the outlet. The lead ingot falls onto the blanking assembly 8. Under the action of gravity, the lead ingot presses the buffer plate 89, and the buffer plate 89 presses the spring, thereby reducing the speed of the lead ingot's descent. The lead ingot falls smoothly into the smelting furnace, avoiding lead splashing caused by the fall of the lead ingot, which poses a safety hazard.
