Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnesium ingot processing technology, specifically to a four-ingot magnesium chip granulation production line. Background Technology
[0002] Magnesium alloys are alloys composed of magnesium as a base and other elements. Due to their superior properties such as low density (approximately 2 / 3 that of aluminum alloys and 1 / 4 that of steel), high specific strength, and good heat dissipation, they are increasingly widely used in high-end manufacturing industries such as aerospace, new energy vehicles, and 3C electronics. In the production and processing of magnesium alloys, processing magnesium blocks into small particles is a key step, and cutting technology has become a commonly used method due to its high efficiency and precision.
[0003] Currently, magnesium alloy granulation production lines mainly operate on a single-ingot or double-ingot basis. Single-ingot production allows for precise control of cutting parameters, better ensuring the uniformity of product particle size and quality stability, and meeting the stringent requirements for the particle size and shape of magnesium chips in various applications.
[0004] The advantages of single or double magnesium ingot production lines are good particle size uniformity and quality stability of the product, small footprint, and greater flexibility. However, correspondingly, the production efficiency of single or double ingot production lines is relatively low, making it difficult to meet the needs of medium or large enterprises. Directly adding production lines would result in relatively high costs and require even more space. Utility Model Content
[0005] This utility model provides a four-spindle magnesium chip pelletizing production line to solve the technical problems in the prior art.
[0006] To solve the above problems, the four-ingot magnesium chip granulation production line provided by this utility model adopts the following technical solution: it includes a chip cutter, which is used to cut magnesium ingots into magnesium alloy particles; the chip cutter includes a frame and a chip cutting mechanism and a pushing mechanism installed on the left and right sides of the frame, and a chip track for placing magnesium ingots is provided between the chip cutting mechanism and the pushing mechanism. There are four chip tracks, so that the chip cutter can process four magnesium ingots at a time.
[0007] A chip breaker is connected to the discharge port of a chip cutter. The chip breaker is used to separate magnesium chips that are stuck together.
[0008] Cyclone feeder is used to collect the scattered magnesium shavings. The feed inlet of the cyclone feeder is connected to the discharge outlet of the chip breaker.
[0009] A pellet mill is used to process magnesium shavings into pellets. The feed inlet of the pellet mill is connected to the discharge outlet of the cyclone feeder. At least two pellet mills are required to ensure pellet quality.
[0010] The material collection mechanism is used to collect finished magnesium alloy particles. The inlet of the material collection mechanism is connected to the outlet of the granulator, and the number of material collection mechanisms is the same as the number of granulators.
[0011] As a further improvement, the feeding mechanism includes a telescopic structure for propelling the magnesium ingot and a gripping structure for gripping the magnesium ingot.
[0012] As a further improvement, the bottom of the chip track is provided with a waste material hole for discharging waste material, and a flap is provided in the waste material hole for controlling the opening and closing of the waste material hole.
[0013] As a further improvement, the chip breaker includes a base, a body mounted on the base, and an explosion-proof motor. The body has a cylindrical cavity, and a core is rotatably assembled inside the body. The core is connected to the explosion-proof motor, and the core is evenly distributed with material-dispersing blades.
[0014] As a further improvement, the inner wall of the cavity is provided with concave and convex surfaces.
[0015] As a further improvement, the mechanism has a conical structure, and the gap between the material handling blade at the feed inlet and the cavity is greater than the gap between the material handling blade at the discharge outlet and the cavity.
[0016] 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 magnesium shavings. 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.
[0017] As a further improvement, the blade is provided with 6-8 groups.
[0018] As a further improvement, the outlet of the cyclone feeder is connected to a chip container for collecting the chips generated in the chip breaker.
[0019] As a further improvement, the material collection mechanism includes an induced draft fan, a finished product tank, and a dust collection tank. The air inlet of the induced draft fan is connected to the discharge port of the granulator, and the induced draft fan, the finished product tank, and the dust collection tank are all connected by pipes.
[0020] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0021] 1. This utility model improves the existing magnesium ingot production line, enabling it to process four magnesium ingots at a time. This significantly improves production efficiency, reduces equipment manufacturing costs, and ensures the quality of finished products.
[0022] 2. By setting up a chip breaker, this utility model can disperse the adhering magnesium chips, ensuring product quality and preventing the magnesium alloy from sticking together and affecting the normal discharge of materials or causing damage to the equipment.
[0023] The inner wall of the chip breaker has a concave-convex structure, which can improve the dispersion effect of magnesium chips. After the magnesium chips enter the chip breaker, the dispersing blades throw the magnesium chips onto the concave-convex surface for high-frequency collision, so as to achieve the purpose of breaking the magnesium chips.
[0024] The core of the chip breaker is conical. The gap between the material-dispersing blade and the cavity at the feed inlet is relatively large, which is conducive to feeding. The gap between the material-dispersing blade and the cavity at the discharge outlet is small, ensuring that each piece of magnesium chip can be thrown onto the inner wall of the machine by the material-dispersing blade. This prevents a small number of adhered magnesium chips from not being thrown away due to insufficient force caused by the large gap between the material-dispersing blade and the cavity.
[0025] 3. This utility model includes two granulators to meet the granulation requirements of a four-spindle production line and ensure the quality of the finished magnesium alloy granules. The granulator adopts a structure similar to a chip breaker, ensuring that each magnesium chip can be ground, resulting in good consistency of the finished magnesium alloy granules.
[0026] 4. The material collection mechanism includes a finished product tank and a dust collection tank. The finished product tank is used to receive finished magnesium alloy particles, and the dust collection tank is used to collect dust, which prevents material from splashing out or dust from spreading, and can ensure that the workshop environment is clean and tidy.

[0033] 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.
[0034] In existing technologies, the production efficiency of single or double magnesium alloy ingot production lines is relatively low, making it difficult to meet the needs of medium or large enterprises. Adding a production line directly would result in significantly higher costs and require more space. Furthermore, different types of magnesium alloys have different compositions, and some types tend to stick together after chipping. If the number of magnesium ingots processed per batch increases, the chip cutting rollers in the chip cutting mechanism will overheat more severely, leading to even more magnesium chip sticking.
[0035] To address the aforementioned issues, this invention utilizes a chip-breaking mechanism to disperse the adhered magnesium chips, thereby ensuring product consistency.
[0036] In addition, this utility model has improved the chip breaking machine. The inner wall of the chip breaking machine is provided with a concave-convex structure, which can improve the dispersion effect of magnesium chips. After the magnesium chips enter the chip breaking machine, the dispersing blade throws the magnesium chips onto the concave-convex surface for high-frequency collision, so as to achieve the purpose of breaking the magnesium chips.
[0037] The core of the chip breaker is conical. The gap between the material-dispersing blade and the cavity at the feed inlet is relatively large, which is conducive to feeding. The gap between the material-dispersing blade and the cavity at the discharge outlet is small, ensuring that each piece of magnesium chip can be thrown onto the inner wall of the machine by the material-dispersing blade. This prevents a small number of adhered magnesium chips from not being thrown away due to insufficient force caused by the large gap between the material-dispersing blade and the cavity.
[0038] The granulator and material collection mechanism are both equipped with two sets, ensuring that they can handle the magnesium shavings generated from the simultaneous processing of four magnesium ingots. The granulator core also has a conical structure, and the gap between the inner wall of the cavity at the granulator outlet and the blades is relatively small, thus ensuring that each piece of magnesium shavings can be ground and discharged, guaranteeing the product quality and consistency of the finished magnesium alloy granules.
[0039] 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.
[0040] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0041] Example 1 of the four-spindle magnesium chip granulation production line provided by this utility model:
[0042] like Figures 1-3 As shown, the four-spindle magnesium chip pelletizing production line includes a power distribution cabinet 2, a hydraulic pump station 1, a touch screen, a chip cutter 3, a chip breaker 4, a cyclone feeder 5, a pelletizer 6, and a material collection mechanism 7.
[0043] 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.
[0044] The chip cutter 3 is used to cut magnesium ingots into magnesium alloy particles. The cutting machine includes a frame 301 and a chip cutter 3 structure and a pusher mechanism 302 installed on the left and right sides of the frame 301. A chip track 303 for placing magnesium ingots is also provided between the chip cutter 3 structure and the pusher mechanism 302. There are four chip tracks 303, which enable the chip cutter 3 to process four magnesium ingots at a time.
[0045] In this embodiment, the chip cutting mechanism 3 includes a chip cutting roller and a chip cutting motor for driving the chip cutting roller to rotate. The pushing mechanism 302 includes a telescopic structure for pushing the magnesium ingot to move and a gripping structure for gripping the magnesium ingot. There are two telescopic structures and four gripping structures. Each telescopic structure is connected to two gripping structures. The telescopic structures generally use hydraulic cylinders, and the gripping structures can use electric grippers or pneumatic grippers. The gripping structures have two main functions: first, to fix the magnesium ingot, and second, to grip and retract excess material.
[0046] The bottom of the chip track 303 has a waste material discharge hole (not shown in the figure) for discharging waste material. A flap is installed inside the waste material discharge hole to control its opening and closing. In this embodiment, the flap is hinged to the waste material discharge hole, and its tilt angle is controlled by a cylinder. When the waste material moves above the waste material discharge hole, the cylinder retracts, the flap flips downwards, changing from horizontal to tilted, the gripping structure releases, and the waste material falls out of the discharge hole and is discharged.
[0047] The chip breaker 4 is used to separate magnesium chips that are stuck together. The feed inlet of the chip breaker 4 is connected to the discharge outlet of the chip cutter 3. The chip breaker 4 includes a base, a body mounted on the base, and an explosion-proof motor. A cylindrical cavity is opened inside the body, and a core is rotatably assembled inside the body. The core is connected to the explosion-proof motor. The core is evenly distributed with material-dispersing blades. The inner wall of the cavity has concave and convex surfaces, which can be adjusted according to actual conditions. It can be a concave-convex spherical structure or a concave-convex platform. The core has a conical structure. The gap between the material-dispersing blades at the feed inlet of the body and the cavity is larger than the gap between the material-dispersing blades at the discharge outlet of the body and the cavity, ensuring that each piece of magnesium chip is thrown onto the inner wall of the body by the material-dispersing blades.
[0048] Cyclone feeder 5 is used to collect the dispersed magnesium shavings. The feed inlet of cyclone feeder 5 is connected to the discharge outlet of chip breaker 4. Since the size of magnesium shavings is relatively large, the chip breaker fan of cyclone feeder 5 adopts a high-pressure centrifugal fan, which includes components such as impeller, casing, air inlet, air outlet, and shaft. The power of the chip breaker fan is 11kw. The chip breaker fan has a similar function to the induced draft fan 701 described below. Its structure and principle are the same, and the only difference is the size and power. The power of induced draft fan 701 is 7.5kw.
[0049] Granulator 6 is used to process magnesium shavings into granules. The feed inlet of granulator 6 is connected to the discharge outlet of cyclone feeder 5. At least two granulators 6 are provided to ensure granulation quality.
[0050] The granulator 6 includes a housing and a rotating core mounted within the housing. The core is evenly distributed with several blades (also called grinders) for grinding magnesium shavings. The internal cavity of the housing is cylindrical, while the core has a conical structure, ensuring that the gap between the inner wall of the cavity at the feed inlet and the blades is larger than the gap between the inner wall of the cavity at the discharge outlet 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 needs. In other embodiments, if high particle shape of aluminum shavings is required, 8 sets of blades are necessary.
[0051] Material collection mechanism 7 is used to collect finished magnesium alloy particles. The inlet of material collection mechanism 7 is connected to the outlet of granulator 6. The number of material collection mechanisms 7 is the same as the number of granulators 6.
[0052] The outlet of the cyclone feeder 5 is connected to a chip collection tank 501 for collecting magnesium chips generated in the chip breaker 4. The chip collection tank 501 and the dust collector 703 have the same structure, and a filter structure is set at the outlet of the tank to prevent dust or chips from being discharged.
[0053] The material collection mechanism 7 includes an induced draft fan 701, a finished product tank 702, and a dust collector 703. The air inlet of the induced draft fan 701 is connected to the discharge port of the granulator 6. The induced draft fan 701, the finished product tank 702, and the dust collector 703 are all connected by pipes.
[0054] 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.
