Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy wheel manufacturing technology, and in particular to a uniform aluminum chip recycling and supply device. Background Technology

[0002] In the production of aluminum alloy wheels, aluminum shavings recycling is a key step for enterprises to reduce costs and increase efficiency. Currently, the industry generally uses a closed large-scale collection system to collect aluminum shavings generated during processing, which are then poured into a smelting pool. This traditional method has significant drawbacks: the aluminum shavings collected in the large-scale collection system are often mixed with cutting fluid, impurities, etc., and the timing and amount of aluminum shavings poured into the smelting pool are not effectively controlled, resulting in a high degree of randomness. When these aluminum shavings mixed with impurities and randomly added are put into the smelting process along with normal aluminum ingots, it will seriously interfere with the quality and compositional stability of the molten aluminum. In addition, the damp aluminum shavings and foreign objects in the large-scale collection system can cause splashing of molten aluminum due to rapid evaporation of moisture during the pouring process, or smelting abnormalities caused by foreign objects mixing into the molten aluminum, threatening personal and equipment safety.

[0003] Therefore, there is an urgent need to design a recycling supply device that can achieve uniform feeding and has efficient filtration and screening functions to improve the product quality and safety of wheel hub production. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a uniform aluminum shavings recycling and supply device. The technical solution adopted by this utility model is as follows: A uniform aluminum scrap recycling and supply device includes a frame with a hopper for collecting aluminum scrap. The bottom of the hopper is connected to a discharge auger, and the front end of the discharge auger is provided with a discharge port corresponding to the smelting pool for uniformly and controllably feeding the aluminum scrap in the hopper into the smelting pool.

[0005] Preferably, a drive motor is fixedly mounted on the frame, a drive wheel is provided at the output end of the drive motor, and a driven wheel is provided at the end of the auger shaft. The drive wheel and the driven wheel are driven by friction transmission through a belt.

[0006] Preferably, the supply device further includes a filtration and separation structure for purifying aluminum chips. The filtration and separation structure includes a strong magnetic adsorption ring disposed at the discharge port for adsorbing and separating magnetic materials such as iron filings and slag mixed in with the aluminum chips.

[0007] Preferably, the bottom of the discharge auger is provided with a drain hole for discharging the cutting fluid and grease carried by the aluminum chips.

[0008] Preferably, the diameter of the drain hole is 2-3 mm.

[0009] Preferably, the discharge auger is arranged in an inclined posture with the front higher than the rear, and the drain hole is opened at the tail end of the discharge auger.

[0010] Preferably, the frame is equipped with a maintenance ladder to facilitate routine maintenance by staff. The beneficial effects of this utility model are as follows: By combining a dedicated collecting hopper with a discharge auger, this utility model achieves timed and quantitative input of aluminum chips into the smelting pool, completely solving the problem of random timing and quantity of input using traditional large hoppers. This ensures the uniformity and stability of the aluminum molten material input process, effectively improving the stability of the aluminum molten material composition and the quality of wheel hub casting. The strong magnetic adsorption ring at the discharge port can accurately adsorb and separate magnetic materials such as iron filings and slag mixed in with the aluminum chips, significantly improving the purity of the aluminum chips entering the smelting pool and reducing the adverse interference of impurities on the aluminum molten material composition, thus ensuring the quality of the aluminum molten material from the source. The drainage holes at the bottom of the discharge auger, arranged at an angle, utilize the liquid's own weight to achieve automatic drainage, requiring no additional power and simplifying the equipment structure. This not only promptly discharges cutting fluid, grease, and other liquids carried by the aluminum chips, reducing the water and oil content of the aluminum chips and minimizing defects such as bubbles and inclusions caused by the vaporization of water and grease during the smelting process, thus improving the purity of the aluminum molten material and smelting efficiency, but also reduces the risk of safety accidents caused by liquid impurities.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figure 1-3As shown, an aluminum shavings recycling and uniform supply device includes a frame 10, on which a collecting hopper 20 is provided for collecting aluminum shavings, providing a stable storage space for subsequent processing. A discharge auger 30 is connected to the bottom of the collecting hopper 20, and a discharge port 31 is provided at the front end of the discharge auger 30 corresponding to the smelting pool, for uniformly and controllably feeding the aluminum shavings from the collecting hopper 20 into the smelting pool. In use, aluminum shavings generated during machining are collected in the collecting hopper 20 for processing. When feeding is required, the discharge auger 30 is activated, and the auger shaft 32 of the feeding auger rotates, pushing the aluminum shavings in the auger shell forward, uniformly and stably feeding them into the smelting pool. During this process, the aluminum shavings in the collecting hopper 20 fall to the auger shell under gravity, achieving continuous feeding from the discharge auger 30.

[0018] This embodiment provides a stable and standardized storage space for the subsequent processing of aluminum scrap by setting up a dedicated collection hopper 20. The discharge auger 30, connected to the collection hopper 20, enables the timed and quantitative feeding of aluminum scrap into the pool, ensuring the uniformity and stability of the aluminum molten material feeding process. This avoids the cumbersome operation and potential contamination caused by using large bags to collect aluminum scrap in traditional methods, while also avoiding the randomness of aluminum scrap feeding time and quantity, reducing adverse interference with the quality of the aluminum molten material.

[0019] In a preferred embodiment, a drive motor 40 is fixedly mounted on the frame 10. The drive motor 40 is connected to the discharge auger 30, providing power for the rotation and feeding of the auger shaft 32. Specifically, a drive wheel 41 is provided at the output end of the drive motor 40, and a driven wheel 42 is provided at the end of the auger shaft 32. The drive wheel 41 and the driven wheel 42 are driven by friction through a belt 43. This transmission method has a simple structure, is easy to install and maintain, and can stably transmit power, ensuring the continuous and stable operation of the discharge auger 30, achieving uniform and quantitative feeding of aluminum chips, and further improving the stability of the aluminum liquid composition and the casting quality of the wheel hub.

[0020] Preferably, the supply device further includes a filtration and separation structure for purifying aluminum chips. The filtration and separation structure includes a strong magnetic adsorption ring 51 located at the discharge port 31, used to adsorb and separate magnetic materials such as iron filings and slag mixed in with the aluminum chips. When the aluminum chips pass through the discharge port 31, magnetic materials such as iron filings generated by equipment and tool wear will be adsorbed onto the surface of the strong magnetic adsorption ring 51 by its magnetic force, improving the purity of the aluminum chips entering the smelting pool and reducing the impact on the composition of the molten aluminum. Operators need to regularly clean the magnetic material on the strong magnetic adsorption ring to ensure the adsorption effect. Preferably, the filtration and separation structure further includes a drain hole 52 located at the bottom of the discharge auger 30 for discharging liquids such as cutting fluid and grease carried by the aluminum chips. The drain hole 52 preferably has a diameter of 2-3 mm to ensure smooth liquid discharge while effectively preventing aluminum chips from leaking out. In actual operation, the cutting fluid and grease carried by the aluminum chips will collect at the bottom of the auger housing and be discharged through the drain hole 52. This improves the purity of the molten aluminum and the smelting efficiency, while reducing the risk of safety accidents caused by liquid impurities.

[0021] Preferably, the discharge auger 30 is arranged in an inclined posture with the front higher than the rear. The drain hole 52 is located at the tail end of the discharge auger 30. The inclined arrangement of the discharge auger 30 allows the cutting fluid and grease collected at the bottom of the auger housing to automatically flow back to the tail end of the discharge auger 30 by its own weight and be discharged through the drain hole 52. This embodiment achieves automatic draining without the need for additional power, simplifies the equipment structure, improves draining efficiency, ensures continuous dehydration and degreasing of aluminum chips during transportation, further improves the cleanliness of aluminum chips, and ensures stable quality of aluminum chips fed into the smelting tank.

[0022] Preferably, the frame 10 is equipped with a dedicated maintenance ladder 60, which facilitates staff to check the internal condition of the equipment, promptly repair any abnormalities, and ensure the normal operation of the equipment. The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
