Description

Technical Field

[0001] This utility model belongs to the field of aluminum ingot production, and in particular relates to a device for cooling and reducing the temperature of hot aluminum ingots. Background Technology

[0002] Aluminum ingots are the raw material for smelting and casting pure aluminum and aluminum alloy products. The main production equipment for aluminum ingots includes aluminum melting furnaces and automatic ingot casting machines. Raw aluminum, other metals, and additives are melted into molten aluminum in the aluminum melting furnace. The molten aluminum flows from the furnace through the outlet channel to the casting channel, and then into the distribution drum of the automatic ingot casting machine. The distribution drum operates synchronously with the ingot casting machine and has multiple evenly distributed outlets aligned with the running aluminum ingot mold. The molten aluminum cools into aluminum ingots in the mold. When the mold reaches the curved bend, a pneumatic hammer strikes the mold, causing the aluminum ingot to fall downwards into the aluminum ingot collection line. The collection line then lowers the aluminum ingot into a cooling bed for gradual cooling.

[0003] In existing technologies, the temperature in production workshops is often high, and the surface of aluminum ingots is still relatively soft before being immersed in water. Immersion in water at a certain speed will cause surface defects. Therefore, it is necessary to improve the cooling device for hot aluminum ingots to solve the problem of surface defects.

The liquid collection tank 102 is V-shaped. After spraying, the water containing impurities and warm water falls into the liquid collection tank 102 and flows into the cooling box 104 through the drain pipe 103. After the wastewater is purified by the filter plate 105, the blades 203 are driven to rotate by the No. 1 motor 204. When the workshop temperature is high and the flow rate needs to be increased, the No. 1 motor 204 increases the speed and speeds up the rotation of the blades 203 to increase the flow rate and enhance the cooling effect. After being pressurized by the diversion pump 201, the water is discharged again, completing the water circulation.

[0024] In this embodiment: the spray assembly 2 includes a diversion pump 201, the output end of the diversion pump 201 is provided with two connecting pipes 205, a speed control box 202 is provided on one side of the diversion pump 201, a blade 203 is rotatably provided in the middle of the speed control box 202, a motor 204 is installed on one side of the blade 203, a connecting seat 206 is provided on the connecting pipe 205, an expansion joint 207 is provided at the end of the connecting pipe 205, a diversion pipe 208 is provided on the side of the expansion joint 207 away from the connecting pipe 205, two telescopic rods 209 are symmetrically installed at both ends of the diversion pipe 208, and a number of spray nozzles 210 are provided at the bottom of the diversion pipe 208. The diversion pump 201 is connected to the cooling box 104 via a pipeline. The connecting pipe 205 is fixed to the support frame 101 via the connecting seat 206. The telescopic rod 209 pushes the diversion pipe 208 to move according to the aluminum ingot specifications, so that the spray nozzles 210 are at a suitable distance from the aluminum ingot. The expansion joint 207 extends and retracts with the movement of the diversion pipe 208. The diversion pump 201 inputs cold water into the connecting pipe 205 fixed by the connecting seat 206. The water enters the diversion pipe 208 through the expansion joint 207 and is then diverted to each spray nozzle 210 to spray the aluminum ingot.

[0025] In this embodiment: the supporting component 3 includes a slide rail 301, which is square. Two rollers 302 are arranged parallel to each other on the slide rail 301. A support frame 303 is provided at the bottom of the rollers 302. The rollers 302 are connected to the support frame 303 by bearings. A second motor 304 is provided at one end of the rollers 302. The second motor 304 is bolted to the support frame 303. A lifting column 305 is installed at the bottom of the support frame 303. A hook 306 is provided at the bottom of the lifting column 305. The hot aluminum ingot is placed in a strainer. The top of the strainer is hung on the hook 306. The lifting column 305 pulls the hook 306 upward.

[0026] Working principle: In use, hot aluminum ingots are placed in a strainer, with the top of the strainer hanging on hook 306. The lifting column 305 pulls hook 306 upwards, causing motor 304 to drive roller 302 to rotate, moving the aluminum ingot along slide rail 301 to between spray nozzles 210. Telescopic rod 209 moves diversion pipe 208 according to the aluminum ingot specifications, ensuring a suitable distance between the spray nozzles 210 and the aluminum ingot. Expansion joint 207 extends and retracts with the movement of diversion pipe 208. Diversion pump 201 inputs cold water into connecting pipe 205 fixed to connecting seat 206. The water passes through expansion joint 207... 07 enters the diversion pipe 208, and then is diverted to each spray nozzle 210 for spraying onto the aluminum ingot. The water containing impurities and warm after spraying falls into the collection tank 102 and flows into the cooling tank 104 through the drain pipe 103. After being purified by the filter plate 105, the wastewater is driven by the No. 1 motor 204 to rotate the blades 203. When the workshop temperature is high and the flow rate needs to be increased, the No. 1 motor 204 increases its speed and speeds up the rotation of the blades 203 to increase the flow rate and enhance the cooling effect. After being pressurized by the diversion pump 201, the water is discharged again, completing the water circulation.
