Description

Technical Field

[0001] The utility model mainly relates to the technical field of aluminum ingot processing equipment, in particular to a cooling water decontamination device for an ingot casting line. Background Art

[0002] Aluminum ingot is an industrial raw material, which is produced by electrolysis of alumina-cryolith. After entering industrial application, aluminum ingots are divided into two categories: cast aluminum alloy and deformed aluminum alloy. Cast aluminum and aluminum alloys are aluminum castings produced by casting method, and deformed aluminum and aluminum alloys are aluminum processed products produced by pressure processing method, such as plates, strips, etc. The main processes include waste aluminum recovery, pretreatment, high-temperature melting, slag stirring, alloy proportioning, ingot casting, circulating cooling water and stacking and warehousing.

[0003] In the aluminum ingot casting process, an aluminum ingot continuous casting unit is required to inject molten aluminum into the mold, and take it out after cooling into a cast billet. The casting process is also the physical process of liquid aluminum crystallizing into solid aluminum. The aluminum ingot after casting needs to be cooled with cooling water. However, due to the recycling of cooling water, waste slag particles and dust particles in the casting process continuously enter the cooling water, causing the cooling water to be turbid. As a result, in the process of cooling the aluminum ingot, impurities will adhere to the aluminum ingot. After the conveying mechanism drives the aluminum ingot out of the cooling water, it affects the glossiness of the aluminum ingot. At the same time, some waste slag will also corrode the surface of the aluminum ingot, affecting the quality of the product. Utility Model Content

[0021] Please refer to the attached Figure 1-3 A cooling water decontamination device for an ingot casting line comprises a split cooling mechanism 1, wherein the split cooling mechanism 1 comprises a cooling trough body 11, a primary filter box 12 and a secondary filter box 13, wherein the primary filter box 12 comprises a first filter trough body 121 and a first cover body 122, wherein filter plates 15 are inserted into multiple openings on the upper side of the first cover body 122, and a first metal hose 16 is arranged between the first filter trough body 121 and the cooling trough body 11, wherein the secondary filter box 13 comprises a second filter trough body 131 and a second cover body 132, wherein multiple heat exchange tubes 14 are penetrated through the second filter trough body 131, and each of the heat exchange tubes 14 is provided with a detachable activated carbon adsorption sleeve 141, and a second metal hose 17 is arranged between the second filter trough body 131 and the first filter trough body 121.

[0022] The above structure realizes the removal of impurities from the circulating cooling water during the continuous casting of aluminum ingots through the split cooling mechanism 1, so as to filter out the waste slag particles and dust particles in the cooling water in time, thereby ensuring that the aluminum ingots are not corroded by the waste slag remaining in the cooling water during stacking storage, and also ensuring the glossiness and cleanliness of the surface of the aluminum ingots, thereby improving the quality of the product. In addition, the structure is stable, the operation is convenient, and it has certain practical value.

[0023] The specific operation is as follows: after the ingots are removed from the mold, the transportation mechanism will transport the aluminum ingots to the cooling tank body 11 for cooling. Driven by the water pump 2, the water in the cooling tank body 11 can be recycled. The water in the cooling tank body 11 enters the first filter tank body 121 through the first metal hose 16, and then passes through multiple filter plates 15 in sequence to filter out large particles of impurities in the water, and then enters the second filter tank body 131 through the second metal hose 17. Under the action of the activated carbon adsorption sleeve 141, smaller particles can be adsorbed to further purify the cooling water. At the same time, under the action of the heat exchange tube 14 and the heat dissipation fan 41, the heat of the cooling water in the second filter tank body 131 is quickly taken away, which is convenient for the subsequent cooling of the aluminum ingots. Subsequently, under the action of the metal reflux hose 18, the cooling water returns to the cooling tank body 11 and is used again.

[0024] Please refer to the attached Figure 1 and attached Figure 2 A metal reflux hose 18 is arranged between the cooling trough body 11 and the second filtering trough body 131, and a water pump 2 is arranged on the metal reflux hose 18.

The bottom of the cooling trough body 11 is connected with a support frame 3 by bolts. The support frame 3 supports the cooling trough body 11. A positioning frame 4 is installed on one side of the second filtering trough body 131 by bolts. A plurality of heat dissipation fans 41 are arranged on the positioning frame 4. Each of the heat dissipation fans 41 is matched with the corresponding heat exchange tube 14. Through the mutual cooperation between the heat dissipation fans 41 and the heat exchange tube 14, the cooling water is quickly cooled down.
