Description

Technical Field

[0001] The invention belongs to the technical field of metal preparation and relates to a cooling device, in particular to an aluminum alloy cooling device. Background Art

[0002] Aluminum alloy is an alloy with aluminum as the base and a certain amount of other alloying elements added. It is one of the light metal materials. Aluminum alloy has many advantages such as light weight, high strength, good corrosion resistance, excellent processing performance, good electrical and thermal conductivity, good aesthetics, recyclability and good economy. These advantages make aluminum alloy widely used in many fields such as aerospace, automobile manufacturing, construction, electronic appliances, transportation, packaging and daily life.

[0003] Aluminum alloy production requires raw material preparation, aluminum ingot production, aluminum alloy smelting and casting, and other processes. Annealing is required in multiple steps in the production environment to improve the strength of the aluminum alloy. Water cooling is used in the traditional production process, but direct water spraying will cause excessive local temperature differences in the aluminum ingots. Excessive stress may be generated during rapid cooling, causing damage or deformation of the casting. Therefore, when using the water cooling method, the cooling rate and temperature gradient need to be controlled. In order to increase the strength of the aluminum ingots during heat treatment, sodium silicate solution, rare earth compound solution and other material strength enhancers are added. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic control and temperature uniform spray type aluminum alloy cooling equipment in view of the above problems existing in the prior art.

The circulating cooling solution reduces the deformation caused by the local low temperature of the material. At the same time, the cooling liquid is heated by the heat emitted by the material, which can reduce the ambient temperature more quickly while increasing the temperature of the cooling liquid and reducing the temperature difference. The turbulent fan can make the material distribution inside the cooling liquid more uniform and increase the performance of the material after it comes out. The storage plate can reduce the contact area and reduce the bending deformation caused by excessive heat dissipation at both ends. BRIEF DESCRIPTION OF THE DRAWINGS

The material rack 14 is loaded with the molten and heated materials and hoisted to the top of the pallet 4 through the crane 1, the lifting ring 16 is separated from the cover 6 and placed on the top of the insulation cover 3, the hydraulic cylinder 22 is extended and retracted up and down, the bellows 32 is squeezed and the coolant is pressed into the spray pipe 8, the cooling liquid is sprayed out through the spray pipe 8 and forms a cooling water mist, which reduces the temperature in the insulation cover 3, and the insulation cover 3 prevents the local temperature from being too low. The temperature of the internal space of the insulation cover 3 is detected by the temperature detector, and the movement of the hydraulic cylinder 22 is controlled to keep the internal temperature space temperature fixed and reduced. The hydraulic cylinder 22 will vibrate when it works, and the solution adhering to the surface of the material will fall due to the vibration, making the temperature distribution more uniform.

[0022] Preferably, the material rack 14 is provided with symmetrically arranged material rack modules 18, and the material rack modules 18 are provided with symmetrically arranged columns 20, and a plurality of storage plates 21 are provided between the columns 20, and a plurality of V-shaped portions 19 are provided on the storage plates 21, and material rods 25 are provided on the V-shaped portions 19.

Both ends of the guide rod 30 are provided with a connecting portion 23 for connecting a steel cable 26. The storage plate 21 is a spring plate, and the material rod 25 is placed on the V-shaped portion 19, and the top of the material rod 25 is abutted by the bottom of the V-shaped portion 19 to form a three-point fixation. The V-shaped block of the spring plate material will retract inward until it reaches a balance with the downward gravity of the upper V-shaped block. The two ends of the material rod 25 are clamped and fixed by the V-shaped blocks. The column 20 will move to both sides due to the extension of the storage plate 21. Under the action of the guide rod 30 and the guide beam 28, the storage plate 21 will maintain a uniform extension length. The V-shaped block makes the material rod 25 regularly distributed. The spray pipe 8 is inserted between the material rods 25. The temperature between the material rods 25 is high. The heat is absorbed by the spray pipe 8 to heat the cooling solution, preventing the liquid from being overcooled and causing local excessive cooling of the material rod 25.

[0025] Preferably, the guide beam 40 is provided with interconnected cables 29, which are in contact with the bottom of the storage plate 21. When the storage plate 21 is suspended and moved, the cables 29 prevent the bottom storage plate 21 from excessively bending and causing the material rods 25 to fall.

[0026] Preferably, a turbulent fan 40 is provided in the bellows 32. When the bellows 32 contracts and expands, pressurized liquid is formed. The pressurized cooling liquid drives the turbulent fan 40 to rotate, so that the mixture in the coolant is more evenly distributed, thereby increasing the cooling effect.
