Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot processing technology, specifically to a two-ingot aluminum ingot chip granulation production line. Background Technology

[0002] In the aluminum product processing industry, aluminum ingot chip granulation production line is a key piece of equipment in aluminum product processing. It turns the chips generated from aluminum ingot processing into granules to facilitate subsequent processing steps.

[0003] Currently, most commercially available aluminum ingot chip granulation production lines use a cutting roller to crush and granulate aluminum ingot chips. However, existing aluminum ingot chip granulation production lines still have some problems during the production process.

[0004] On the one hand, during the continuous high-speed chip cutting process, the cutter roller generates a lot of heat due to the intense friction with the aluminum ingot chips, and the heat dissipation efficiency is low, which causes the temperature of the cutter roller to rise sharply and is prone to overheating and deformation. This not only affects the service life of the cutter roller, but also reduces the chip cutting accuracy, thereby reducing the quality of the granulated products.

[0005] On the other hand, due to the material properties of aluminum (aluminum has good ductility, plasticity and low melting point, etc.), aluminum chips generated during the cutting process are easy to stick to the surface of the cutter roller. As the adhesive accumulates, it will change the original structural parameters of the cutter roller, affect the balance and stability of the cutter roller operation, increase the risk of equipment failure, and clean up the adhesive aluminum chips. At the same time, cleaning up the adhesive aluminum chips will consume a lot of manpower and time costs, which seriously restricts the continuous and efficient operation of the production line. Utility Model Content

[0006] This utility model provides a two-ingot aluminum ingot chip granulation production line to solve the technical problems in the prior art.

[0007] To solve the above problems, the two-ingot aluminum ingot chipping and granulation production line provided by this utility model adopts the following technical solution: it includes a chipper for chipping aluminum ingots; the chipper includes a frame, a chipping mechanism mounted on the frame, and a pushing mechanism for moving the aluminum ingots. The pushing mechanism has at least two sets, allowing the two sets to alternately push the aluminum ingots to reduce heat generation in the chipping mechanism; the frame also has a water supply structure for cooling the chipping mechanism; the pushing direction of the pushing mechanism is defined as the left-right direction.

[0008] The vibrating dewatering device is used to dry aluminum chips. The discharge port of the chip cutter is connected to the inlet of the vibrating dewatering device.

[0009] The cyclone feeder is used to convey aluminum chips, and the discharge port of the vibrating dewatering device is connected to the inlet of the cyclone feeder.

[0010] A pellet mill is used to grind aluminum shavings into pellets. The feed inlet of the pellet mill is connected to the discharge outlet of the cyclone feeder.

[0011] Material collection mechanism, used to collect finished products processed into granules.

[0012] As a further improvement, a chip track for limiting the aluminum ingot is provided between the chipping mechanism and the pushing mechanism.

[0013] As a further improvement, a flap is provided at the bottom of the chip track, and an adjusting cylinder is provided below the flap to control the tilt of the flap so as to discharge the excess material.

[0014] As a further improvement, a pressure cylinder is also provided above the chip track to limit the aluminum ingot's position and prevent the aluminum ingot from tilting during the chip cutting process.

[0015] As a further improvement, the water supply structure includes a water inlet and a water outlet located on the front and rear sides of the frame, with both the water inlet and the water outlet positioned on the side closest to the chip cutting mechanism.

[0016] As a further improvement, the bottom of the vibration dehydration device is provided with a drain for collecting cooling water, and the other end of the drain is connected to an external circulating water tank.

[0017] As a further improvement, the pellet mill includes a housing and a rotating core mounted inside the housing. The core is evenly distributed with several blades for grinding aluminum chips. The cavity inside the housing is cylindrical, and the core is conical, such that the gap between the inner wall of the cavity at the feed inlet of the pellet mill and the blades is greater than the gap between the inner wall of the cavity at the discharge outlet of the pellet mill and the blades.

[0018] As a further improvement, the blade is provided with 6-8 groups.

[0019] As a further improvement, the material collection mechanism includes a receiving tank, a dust collector, and an induced draft fan. The inlet of the receiving tank is connected to the outlet of the granulator, and the receiving tank, the dust collector, and the induced draft fan are all connected by pipes.

[0020] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0021] 1. The chip cutter of this utility model can hold two aluminum ingots at a time, and two sets of pushing mechanisms alternately push the aluminum ingots to cut chips. In this way, while ensuring processing efficiency, the temperature of the cutting roller of the chip cutting mechanism is avoided from being too high due to continuous high-frequency operation.

[0022] The ventilation system incorporates a water supply structure, continuously adding water during the cutting process. This water flow reduces the risk of damage to the cutter roller, further preventing overheating and deformation or aluminum chips from adhering to the roller, thus significantly extending its service life.

[0023] The water used for cooling remains relatively clean after use, so a water tank can be set up to simply filter the used water before recycling, reducing water consumption.

[0024] 2. This invention utilizes a vibration dehydration device to dehydrate wet aluminum shavings using the principle of linear vibration, ensuring the shavings remain dry. Furthermore, this invention employs a cyclone feeder for conveying the aluminum shavings; the high-speed airflow removes any residual moisture from the surface of the shavings, further drying them.

[0025] 3. The material collection mechanism includes a receiving tank and a dust collection tank. The receiving tank is used to receive finished particles, and the dust collection tank is used to collect dust. When the equipment is running, the induced draft fan first conveys the finished particles to the receiving tank, and the excess dust enters the dust collection tank. A small amount of water vapor is discharged with the gas, which avoids material splashing or dust diffusion. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] In the existing technology, during the aluminum ingot chip granulation process, on the one hand, the cutter roller generates a lot of heat due to the intense friction with the aluminum ingot chips during continuous high-speed chip cutting, and the heat dissipation efficiency is low, which causes the temperature of the cutter roller to rise sharply and is prone to overheating and deformation. This not only affects the service life of the cutter roller, but also reduces the chip cutting accuracy, thereby reducing the quality of the granulated product. In addition, it also easily causes aluminum chips to stick to the cutter roller.

[0033] To address the aforementioned issues, this invention modifies the chip cutter into a dual-push mechanism, allowing the chip cutter to hold two aluminum ingots at a time. The two ingots are cut alternately, which reduces the cutting frequency, decreases heat generation, and distributes the heat at both ends of the cutter roller, thus accelerating heat dissipation. Furthermore, although the aluminum ingot cutting frequency is reduced, the production efficiency is not reduced due to the alternating cutting of the two ingots. In addition, the aluminum ingot cutting frequency can be adjusted according to actual conditions to improve production efficiency.

[0034] The chipper is also equipped with a water supply structure. The water flow first wets the aluminum ingot and then flows to the cutting roller of the chipping mechanism to prevent the cutting roller from overheating and deforming. At the same time, the water flow can also carry away the aluminum chips that are stuck to the cutting roller, preventing the aluminum chips from adhering to the cutting roller and sticking to the cutting roller as the temperature of the cutting roller rises.

[0035] Since adding water would make the aluminum shavings wet, a vibration dehydration device is also included. This device uses linear vibration to dehydrate the wet aluminum shavings, ensuring they remain dry. Furthermore, this invention employs a cyclone feeder for conveying the aluminum shavings. The high-speed airflow removes any residual moisture from the surface of the shavings, further drying them.

[0036] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0037] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0038] Example 1 of the two-ingot aluminum ingot chip granulation production line provided by this utility model:

[0039] like Figure 1 and Figure 2 As shown, the two-ingot aluminum ingot chip granulation production line includes a power distribution cabinet 2, a hydraulic pump station, a touch screen, a chip cutter 3, a vibrating dewatering device 4, a cyclone feeder 5, a granulator 6, and a material collection mechanism 7.

[0040] Distribution cabinet 2 is mainly used for power distribution, motor monitoring, and control systems. The hydraulic pump supplies oil to the drive unit. The touchscreen is mainly used for equipment operation control, status switching, or emergency intervention. All of the above are existing technologies, and their detailed structures will not be described here.

[0041] A chip cutter 3 is used for cutting aluminum ingots. The chip cutter 3 includes a frame 305, a chip cutter 3 structure mounted on the frame 305, and a pusher mechanism 301 for moving the aluminum ingots. The pushing direction of the pusher mechanism 301 is defined as left and right. The chip cutter 3 structure includes a cutter roller rotatably mounted on the frame 305 for cutting aluminum ingots and a chip cutting motor for driving the cutter roller to rotate. In this embodiment, there are two sets of pusher mechanisms 301, so that the two sets of pusher mechanisms 301 alternately push the aluminum ingots to reduce the heat generation of the chip cutter 3 structure. In other embodiments, the number of pusher mechanisms 301 can also be increased. The pusher mechanism 301 includes a hydraulic cylinder for controlling extension and retraction and an electric gripper (or pneumatic gripper). The purpose of using an electric gripper is to facilitate the retraction of excess material.

[0042] The frame 305 is also equipped with a water supply structure (not shown in the figure) for cooling the chip cutter 3. The water supply structure includes a water inlet and a water outlet on the front and rear sides of the frame 305. Both the water inlet and the water outlet are located on the side closer to the chip cutter 3. The purpose of the water outlet is to prevent water overflow and allow excess water to be discharged. In addition, in this embodiment, the frame 305 is inclined, with the side closer to the chip cutter 3 being lower than the side closer to the pusher mechanism 301, to prevent cooling water from flowing towards the pusher mechanism 301. In this embodiment, the aluminum ingot and the cutter roller are moistened by direct water injection. The water first wets the aluminum ingot and then flows onto the cutter roller. In other embodiments, the cutter roller can also be moistened by spraying from a spray head.

[0043] A chipping track 302 for limiting the aluminum ingot is provided between the chipping mechanism 3 and the pushing mechanism 301.

[0044] The bottom of the chip track 302 is equipped with a flap (not shown in the figure), and below the flap is an adjusting cylinder for controlling the tilt of the flap to discharge excess material. In this embodiment, the flap is hinged to the frame 305, and the adjusting cylinder is hinged below the flap. The tilt angle of the flap is controlled by extending and retracting the adjusting cylinder to facilitate the discharge of excess material. In other embodiments, an excess material hole can also be provided, and the opening and closing of the excess material hole can be controlled by a sliding baffle.

[0045] Above the chip cutting track 302, a pressure cylinder 304 is also provided to limit the upward movement of the aluminum ingot, preventing the aluminum ingot from tilting during the chip cutting process. In this embodiment, the pressure cylinder 304 is connected to the pusher mechanism 301, and the pressure cylinder 304 moves with the electric gripper.

[0046] In this embodiment, the movement of the pushing mechanism 301 can be controlled by sensors. For example, sensors can be set at the position corresponding to the flip plate, the middle position of the frame 305, and the position near the cutter roller. When the pushing mechanism 301 pushes the aluminum ingot toward the cutter roller, the sensor at the middle position of the frame 305 is triggered, and the pressing cylinder 304 descends to limit the upper part of the aluminum ingot, preventing the aluminum ingot from tilting during chipping. After the aluminum ingot is chipped, the sensor near the cutter roller is triggered, and the pushing mechanism 301 grabs the remaining material and retracts. When it retracts to the position corresponding to the flip plate, the pushing mechanism 301 releases the grab, the flip plate tilts, and the remaining material is discharged.

[0047] The vibrating dewatering device 4 is used to dry aluminum chips. The discharge port of the chip cutter 3 is connected to the feed port of the vibrating dewatering device 4. The bottom of the vibrating dewatering device 4 is provided with a drain for collecting cooling water, and the other end of the drain is connected to an external circulating water tank. The vibrating dewatering device 4 can be a conventional vibrating screen, and its structure will not be described in detail in this embodiment.

[0048] The cyclone feeder 5 is used to convey aluminum chips. The outlet of the vibrating dewatering device 4 is connected to the inlet of the cyclone feeder 5. Because the aluminum chips are relatively large, the blower of the cyclone feeder 5 is a high-pressure blower with a power of 11kW. This ensures that the high-speed airflow conveys the aluminum chips to the storage tank of the cyclone feeder 5. In addition to conveying materials, the high-speed airflow of the cyclone feeder 5 can also remove moisture from the surface of the aluminum chips, further drying them.

[0049] The granulator 6 is used to grind aluminum shavings into granules. The feed inlet of the granulator 6 is connected to the discharge outlet of the cyclone feeder 5. The granulator 6 includes a housing and a rotating core mounted inside the housing. The core is evenly distributed with several blades (also called grinders) for grinding aluminum shavings. The internal cavity of the housing is cylindrical, while the core has a conical structure, such that the gap between the inner wall of the cavity at the feed inlet of the granulator 6 and the blades is larger than the gap between the inner wall of the cavity at the discharge outlet of the granulator 6 and the blades. The target powder mesh size corresponds to the number of blades. In this embodiment, 6 or 7 sets of blades are sufficient to meet conventional granulation requirements. In other embodiments, if high particle shape of the aluminum shavings is required, 8 sets of blades are needed.

[0050] The material collection mechanism 7 is used to collect the finished product processed into granules. The material collection mechanism 7 includes a receiving tank 701, a dust collector 702, and an induced draft fan 703. The inlet of the receiving tank 701 is connected to the outlet of the granulator 6. The receiving tank 701, the dust collector 702, and the induced draft fan 703 are all connected by pipes. In this embodiment, the induced draft fan 703 can be a medium-pressure fan with a power of 5.5kW.

[0051] While this specification has shown and described numerous embodiments of the present invention, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of the present invention. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
