Description

Technical Field

[0001] The utility model relates to aluminum ingot production and processing equipment, in particular to an aluminum ingot cooling system and an aluminum ingot production system, belonging to the technical field of aluminum ingot production and processing. Background Art

[0002] Aluminum ash slag is an important waste in the aluminum industry, in which the aluminum content can reach 10-30%. Recycling aluminum resources from aluminum ash slag can reduce costs, protect the environment, save energy and improve resource utilization, which has huge economic and social effects.

[0003] At present, the process of recovering aluminum from aluminum ash slag is relatively mature. For example, a Chinese patent with publication number "CN 116240394A" discloses a method for resource utilization of recycled aluminum aluminum ash slag, which specifically includes the following production steps: S1: screening, screening the aluminum ash slag, and obtaining two different types of aluminum ash slag, fine material and coarse material, through a screening machine; S2: grinding, grinding and crushing the aluminum ash slag obtained in step S1 by a grinder; S3: screening, screening the powdered aluminum ash slag obtained in step S2 again; S4: smelting, placing the aluminum particles obtained in step S3 in a smelting furnace for heating and smelting; S5: extracting the slag obtained in step S4 again; aluminum ash slag with different particle sizes can be obtained by screening, and the two types of aluminum ash slag can be efficiently ground and crushed by grinding. By screening out powdered aluminum ash slag with particle sizes in the same range, the next step of smelting can be accelerated, and aluminum liquid can be obtained by smelting. The aluminum liquid in the slag can be extracted to the maximum extent by re-extraction.

[0004] At present, the production process of aluminum ingots is generally as follows: adding aluminum material to a smelting pot, feeding the molten aluminum after smelting in the smelting boiler to the aluminum ingot mold on the aluminum ingot forming conveyor belt to form, cooling it by a spray cooling mechanism and transferring it to the aluminum ingot finished product conveyor belt, and then removing it by a robot for storage. A typical problem of the existing production line is that a large amount of spray water is consumed during the aluminum ingot forming process, and the cooling effect is not good, which leads to the high temperature of the aluminum ingot finished product on the aluminum ingot finished product conveyor belt, which not only affects the life of the equipment, but also poses a huge safety hazard. In addition, a Chinese patent with the announcement number "CN103464698B" discloses a cooling device for aluminum ingot production, and proposes a cooling method in which multiple cooling methods are combined (using the water in the cooling tray to indirectly cool the aluminum ingot in the aluminum ingot mold to avoid the generation of a large amount of water vapor; while using the cooling pool to cool the aluminum ingot mold to reduce the temperature), which has problems such as low cooling efficiency and poor cooling effect. Utility Model Content

[0006] In order to achieve the above technical objectives, the technical solutions adopted by the present utility model are specifically described as follows:

In the multi-stage circulation spray device, the water sprayed by the rear-stage circulation spray device is used as the circulation spray water for the front-stage circulation spray device.

[0013] Preferably, the stepped circulation spray mechanism is a three-stage circulation spray device, including a primary spray head, a primary water collection tank, a secondary spray head, a secondary water collection tank, a tertiary spray head and a tertiary water collection tank. According to the direction of the material, the primary spray head, the secondary spray head and the tertiary spray head are sequentially arranged above the middle section of the aluminum ingot conveying mechanism.

The primary spray head is connected to the primary water collection tank through a primary circulation water pipe and a water pump, the secondary spray head is connected to the secondary water collection tank through a secondary circulation water pipe and a water pump, and the tertiary spray head is connected to an external cold water source through a water delivery pipe. The primary water collection tank, the secondary water collection tank and the tertiary water collection tank are arranged in a row in sequence, and the horizontal heights of their tops increase successively, so that the water in the tertiary water collection tank can flow into the secondary water collection tank after overflow, and the water in the secondary water collection tank can flow into the primary water collection tank after overflow.

[0014] Preferably, the first-level water collection tank, the second-level water collection tank and the third-level water collection tank are a large water collection tank with an inclined bottom, which is separated by a first-level partition and a second-level partition.

[0015] Preferably, an overflow hole is provided on the upper part of the side wall of the primary water collecting tank close to the front circulating water tank. The height of the overflow hole is lower than the top height of the primary partition. The water in the primary water collecting tank flows into the front circulating water tank through the overflow hole.

[0016] Preferably, the step circulation spray mechanism further comprises a middle section sealing cover. The middle section sealing cover is arranged above the primary spray head and the secondary spray head. Preferably, a secondary exhaust cover connected to the inner cavity of the middle section sealing cover is also arranged on the top of the middle section sealing cover.

[0019] Preferably, the aluminum ingot conveying mechanism is one of a steel belt conveyor, a chain plate conveyor, and a conveying trolley. Preferably, the aluminum ingot conveying mechanism is an inclined design with a material input end lower than its material output end.

[0020] According to a second embodiment of the present invention, an aluminum ingot production system is provided:

[0021] An aluminum ingot production system comprises an ingot casting mechanism, an aluminum ingot forming conveyor belt and an aluminum ingot cooling system as described in the first embodiment, which are sequentially arranged in series. An aluminum ingot mold is also arranged on the aluminum ingot forming conveyor belt.

[0022] Preferably, the aluminum ingot production system further comprises an aluminum ingot finished product conveyor belt, a stacking robot and an aluminum ingot storage rack which are sequentially arranged in series downstream of the aluminum ingot cooling system as described in the first embodiment.

[0023] In the utility model, the aluminum ingot forming conveyor belt, the aluminum ingot conveying mechanism, and the aluminum ingot finished product conveyor belt are sequentially connected in series, or the three are an integral conveyor belt, which can be reasonably designed and selected according to actual working conditions.

[0024] In the utility model, the front circulation spray mechanism includes a front sealing cover, a front spray head and a front circulation water pool. The front circulation spray mechanism is arranged at the front end of the aluminum ingot conveying mechanism. The aluminum material with the highest temperature is first cooled by the front circulation spray mechanism, and the cooling water is repeatedly circulated in the front circulation spray mechanism until the temperature of the circulating water rises to a certain temperature (for example, it needs to be discharged through the drain valve and replaced with new water after it is higher than 80°C) or the water volume is insufficient (when the water volume in the circulating water pool is lower than the set water level), so that the circulating water cannot meet the initial cooling demand for the high-temperature aluminum material. At this time, cold water needs to be added to the circulating water pool (for example, cold water is injected into the front circulation water pool through a water supply pipe and a water pump, or water is added through the overflow hole between the primary water collecting tank). In addition, by providing a front sealing hood (for example, supported by a steel bracket and arranged above the aluminum ingot conveyor belt) and a top main exhaust hood connected to the interior thereof above the front end of the front aluminum ingot conveying mechanism, the water vapor generated during the preliminary cooling of the high-temperature aluminum material can be collected and extracted for utilization. In other words, the front circulating spray mechanism can achieve preliminary cooling of the high-temperature aluminum material on the one hand, and obtain hot steam that can be reused on the other hand, thereby realizing sensible heat recovery of the high-temperature aluminum material.

[0025] In the utility model, the stepped circulation spray mechanism includes a multi-stage circulation spray device, for example, a three-stage circulation spray device, including a primary spray head, a primary water collection tank, a secondary spray head, a secondary water collection tank, a tertiary spray head and a tertiary water collection tank, etc. The aluminum material preliminarily cooled by the pre-circulation spray mechanism still has a certain high temperature, and is stepped cooled by the stepped circulation spray mechanism. Specifically, the aluminum material after preliminary cooling first enters the primary cooling zone of the stepped circulation spray mechanism, and the primary spray head uses water from the primary water collection tank to perform primary cooling on the aluminum material. The water that passes through the material layer falls into the primary water collection tank for recycling. Then the aluminum material after primary cooling enters the secondary cooling zone, and the secondary spray head uses water from the secondary water collection tank to perform secondary cooling on the aluminum material. The water that passes through the material layer falls into the secondary water collection tank for recycling (circulated for the secondary spray head and replenishing water to the primary water collection tank). Then, the aluminum material after secondary cooling enters the tertiary cooling zone, and the tertiary spray head uses external cold water to perform tertiary cooling on the aluminum material. The water that passes through the material layer falls into the tertiary water collection tank for recycling (circulated for the tertiary spray head and replenishing water to the secondary water collection tank). The aluminum material is cooled in multiple stages through the stepped circulation spray mechanism in which the cooling water temperature is gradually reduced, and the cooling water is recycled in countercurrent (relative to the material direction). While improving the cooling efficiency of the aluminum material, the use of cooling water is greatly reduced, saving production costs.

[0026] Furthermore, since the temperature of the aluminum material after preliminary cooling is relatively high, a middle sealing cover and an auxiliary exhaust hood arranged on the top of the middle sealing cover are provided above the first-stage spray head and the second-stage spray head of the stepped circulation spray mechanism, so as to recover the hot steam generated during the first-stage cooling and the second-stage cooling process for secondary utilization, thereby further improving the sensible heat recovery effect of the aluminum material.

[0027] In the utility model, the water in the primary water collecting tank, the secondary water collecting tank and the tertiary water collecting tank is used in a countercurrent circulation. The countercurrent circulation mode of the water flow can be achieved by countercurrent transportation through a water pump and a pipe, or by gravity. In the utility model, in order to reduce energy consumption, the preferred implementation scheme is to adopt countercurrent transportation. The three water collecting tanks are closely connected to form a row, but the heights of the primary water collecting tank, the secondary water collecting tank and the tertiary water collecting tank are gradually increased. Overflow holes are provided between the primary water collecting tank and the secondary water collecting tank, and between the secondary water collecting tank and the tertiary water collecting tank. The gravity overflow of water is achieved through the height difference and overflow holes of each water collecting tank. Alternatively, a large water collecting tank with an inclined bottom is divided into three water collecting tanks (from low to high, the first-level water collecting tank, the second-level water collecting tank, and the third-level water collecting tank) by two partitions distributed along the inclined direction, and the height of the partition between the first-level water collecting tank and the second-level water collecting tank is lower than the height of the partition between the second-level water collecting tank and the third-level water collecting tank, thereby meeting the countercurrent transportation of cooling water.

[0028] In the utility model, a post-atomizing cooling mechanism is added to perform a final cooling treatment on the aluminum material. A low-temperature humid air flow is formed in the post-sealed cover of the post-atomizing cooling mechanism by spraying atomized water and inhaling cold air. The low-temperature humid air flow flows over the aluminum ingot to further cool the aluminum ingot without causing the aluminum ingot to be over-humidified.

[0029] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0030] 1: The utility model realizes multiple continuous cooling of the aluminum ingot through the reasonable design of the front circulation spray mechanism, the step circulation spray mechanism and the rear atomization cooling mechanism, which ensures and improves the cooling effect and efficiency of the aluminum ingot, while saving the consumption of cooling water, and further recycles the sensible heat of the aluminum ingot. The system has low energy consumption and is more environmentally friendly.

[0031] 3: The aluminum ingot cooling system and aluminum ingot production system of the utility model have a simple overall structure, ingenious design, good cooling effect on the aluminum ingot, low water consumption, convenient operation and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
