Description

TECHNICAL FIELD

[0001] The utility model relates to the field of mother alloy processing technology, especially to a hopper for receiving mother alloy ingots. BACKGROUND

[0002] The mother alloy ingot refers to an alloy ingot shaped product formed through a casting process in a metal alloy production process. The mother alloy ingot is usually mixed by multiple metal elements, and after melting and cooling in a mold, a solid block of a certain size and shape is formed and used for subsequent processing, melting, or as raw material for other alloys.

[0003] In related technologies, the mother alloy needs to be screened and collected by a hopper after being cast and formed, and the mother alloy ingots that exceed the limit (not screened out) are broken by a knocking tool to reach the required size, so as to ensure that the final mother alloy ingot meets the qualified requirements.

[0004] However, in the traditional hopper, the screen plate is horizontally arranged, and for relatively hard or large-sized alloy ingot blocks, it cannot be effectively screened out and broken, so it is accumulated on the screen plate, thereby affecting the efficiency of the screening operation, and manual breaking is also required, which is time-consuming and laborious, and affects the quality and production efficiency of the mother alloy. SUMMARY

[0005] The utility model discloses a hopper for receiving mother alloy ingots to solve the problem that in the traditional hopper, the screen plate is horizontally arranged, and for relatively hard or large-sized alloy ingot blocks, it cannot be effectively screened out and broken, so it is accumulated on the screen plate, thereby affecting the efficiency of the screening operation, and manual breaking is also required, which is time-consuming and laborious, and affects the quality and production efficiency of the mother alloy.

[0029] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0030] like Figures 1 to 4 As shown, this utility model discloses a hopper for receiving master alloy ingots, including a hopper body 1 and a receiving plate 2. The hopper body 1 has a cavity for accommodating the master alloy ingots. The hopper body 1 is made of high-temperature resistant, wear-resistant, and high-strength steel. During operation, the hopper body 1 can withstand the high temperature of the master alloy ingots and the impact force generated during their fall into the cavity. The receiving plate 2 is located at the top of the hopper body 1 and is used for preliminary screening and crushing of the master alloy ingots that have fallen from the ingot mold. The receiving plate 2 has multiple holes 3. Depending on the required size of the holes 3, the holes 3 are used to screen out master alloy ingots exceeding the specified size, allowing smaller master alloy ingots that meet the required size to pass through the receiving plate 2 and fall into the cavity for collection. Larger master alloy ingots that do not meet the required size are placed on the receiving plate 2 for further crushing. In one example, the distance between two adjacent holes 3 is 25 mm to achieve the desired crushing and screening effect of the master alloy ingots.

[0031] The receiving plate 2 is composed of multiple screen plates. Two adjacent screen plates are connected to each other. The connection method can be welding, hinge, etc., and can be adapted according to the needs. The number of screen plates can be two, four or six, as long as it can achieve the screening of the master alloy ingot. The screen plates are inclined relative to the bottom of the hopper body 1, so that there are protrusions at the connection between two adjacent screen plates. The protrusions can generate concentrated impact points, thereby breaking larger master alloy ingots into smaller master alloy ingots.

[0032] After the master alloy is cast, it is transported to the demolding area by the casting flatcar. The ingot mold is rotated 90°, and the master alloy ingot falls out of the mold due to gravity. During the fall of the master alloy ingot, the inclined screen plate in the master alloy hopper can prevent a large number of master alloy ingots from accumulating, thus effectively separating the larger master alloy ingots from the smaller ones. At the same time, the larger master alloy ingots can impact the protrusions during the fall. The protrusions can generate a large counter-impact force on the master alloy ingots, thereby breaking the larger master alloy ingots into pieces of appropriate size. This controls the size of the master alloy ingots within the required range to meet the needs, and the pieces fall into the cavity of the hopper body 1 for subsequent operations.

[0033] In this application, by setting up a hopper body and a receiving plate with multiple holes, the multiple holes are used to screen out master alloy ingots that exceed the size limit. At the same time, the receiving plate is composed of multiple screen plates, which are set at an inclination relative to the bottom of the hopper body. This ensures that the master alloy ingots falling onto the receiving plate have a more concentrated impact point, thereby achieving control over the size of the master alloy ingots. It can also reduce the concentrated accumulation of master alloy ingots, reduce the intensity of manual labor, and thus improve work efficiency.

[0034] In some embodiments, such as Figures 1 to 4 As shown, the end of the receiving plate 2 is fixedly connected to the hopper body 1. The connection method can be adapted as needed. In one example, the end of the receiving plate 2 is welded to the side wall of the hopper body 1, making the receiving plate 2 more stable during use and preventing displacement or damage when subjected to the weight and impact force of the master alloy ingot. In the height direction of the hopper body 1 (e.g., Figure 1 In the z-direction shown, the receiving plate 2 and the bottom of the hopper body 1 have a predetermined distance, which increases the accommodating space in the inner cavity. After a large number of smaller master alloy ingots pass through the receiving plate 2 and collect in the hopper body 1, it is convenient for subsequent centralized processing. The shape of the receiving plate 2 can be L-shaped or V-shaped. In one example, as shown... Figure 1 As shown, the receiving plate 2 has a V-shaped structure. The V-shaped receiving plate 2 can provide a smooth guiding effect, making it easier for larger master alloy ingots to break along the V-shaped guiding direction after impact and fall into the hopper body 1 through the holes 3. This effectively avoids the master alloy ingots from being unable to pass through the screen holes due to excessive accumulation, thereby reducing jamming and blockage and improving screening efficiency.

[0035] In some embodiments, continuing to refer to Figures 1-2, the receiving plate 2 is composed of two screen plates, including a first screen plate 21 and a second screen plate 22. The first screen plate 21 and the second screen plate 22 can be welded together or are an integral structure, and can be adapted as needed, along the width direction of the hopper body 1 (e.g., ...). Figure 1(As shown in the y-direction), the sieve plate and the hopper body 1 have a preset angle. In one example, the first sieve plate 21 has a preset angle with the side wall of the hopper body 1, so that the first sieve plate 21 is inclined on the side wall of the hopper body 1. During the screening process, a large number of master alloy ingots can slide down the inclined surface of the first sieve plate 21 through the hole 3 into the inner cavity. In another example, the second sieve plate 22 has a preset angle with the side wall of the hopper body 1, so that the second sieve plate 22 is inclined on the side wall of the hopper body 1. The application process is the same as that of the first sieve plate 21, and will not be described in detail in this application. In another example, both the first sieve plate 21 and the second sieve plate 22 have preset angles with the side wall of the hopper body 1, so that both the first sieve plate 21 and the second sieve plate 22 are inclined on the side wall of the hopper body 1. During screening, a large number of master alloy ingots are evenly distributed on the first sieve plate 21 and the second sieve plate 22 and screened through the hole 3, effectively ensuring working efficiency and avoiding blockage.

[0036] In some embodiments, the first screen plate 21 and the second screen plate 22 are integrally formed. This integral structure enhances strength and support, reduces stress concentration at structural connections, and makes the overall stress distribution on the receiving plate 2 more uniform, preventing breakage or wear. Along the width direction of the hopper body 1 (as shown in Figure 3, the y-direction), the preset angle between the first screen plate 21 and the second screen plate 22 and the hopper body 1 is between 50° and 160°. In one example, when the preset angle is 50°, the falling speed of the master alloy ingot is relatively slow, suitable for processing a large number of smaller alloy ingots, facilitating the rapid passage of the master alloy ingot through the hole 3. In another example, when the preset angle is 160°, the impact force on larger master alloy ingots can be increased, allowing larger, defective master alloy ingots to be effectively broken or have their falling trajectory adjusted after impact, helping to accelerate the decomposition of larger master alloy ingots and reduce their dwell time on the receiving plate 2, thereby improving screening efficiency.

[0037] In some embodiments, such as Figures 1 to 3 As shown, the hopper body 1 includes a cuboid-structured receiving area 11 and a discharge area 12. The receiving area 11 is used to receive qualified master alloy ingots, and the discharge area 12 is inclined relative to the receiving area 11. The inclined discharge area 12 allows the falling master alloy ingots to collect in the receiving area 12, thereby effectively concentrating and processing them. In one example, as... Figures 1 to 3 As shown, the two outer side walls of the hopper body 1 are welded with lifting lugs 4 for use with crane hooks, which lift the hopper containing the screened master alloy ingots and transport it to the required area for subsequent operations.

[0038] In some embodiments, such as Figures 1 to 4As shown, the discharge zone 12 includes a guide plate 120 and two baffles 121. The guide plate 120 is fixedly connected to the bottom of the receiving zone 11. The guide plate 120 has a trapezoidal structure, which allows the master alloy ingot to flow smoothly and orderly into the required area. The guide plate 120 is made of wear-resistant and high-temperature resistant material, such as heat-resistant steel, to ensure that its strength and function will not be affected by friction or high temperature during long-term use. Each baffle 121 is connected to the side wall of the receiving zone 11. The baffle 121 is used to restrict the lateral flow of the master alloy ingot, prevent the master alloy ingot from deviating from the predetermined flow path due to gravity or vibration, and also effectively prevent the master alloy ingot from scattering in the receiving zone 11, so that the master alloy ingot can pass through the discharge zone 12 more orderly.

[0039] In some embodiments, along the extending direction of the hopper body 1 (e.g. Figure 4 As shown in the x direction, the guide plate 120 has an inclined angle between the bottom of the receiving area 11 and the guide plate 120, which is 130° to 170°. After a certain amount of master alloy ingot is received, it needs to be poured into the required area for subsequent operations. Since the master alloy ingot is usually heavy and has strong inertia, the master alloy ingot can naturally flow from the receiving area 11 into the required area through the inclined guide plate 120 by gravity, avoiding the master alloy ingot from being stuck in the hopper and ensuring a continuous workflow.

[0040] Along the width direction of the hopper body 1 (e.g.) Figure 2 (As shown in the y-direction), one end of the baffle 121 extends toward the interior of the cavity. One baffle 121 can extend into the cavity, or two baffles 121 can extend into the cavity. Figure 2 As shown, this application employs a baffle 121 extending into the cavity. During use, the baffle 121 enhances the stability of the hopper and the confinement of the master alloy ingot, effectively preventing lateral overflow of the master alloy ingot during screening and flow. It also helps to better control the flow path of the master alloy ingot inside the hopper. The baffle 121 can also guide the master alloy ingot along a predetermined flow direction, avoiding a decrease in screening efficiency caused by irregular flow or material accumulation.

[0041] In some embodiments, the shape of the hole 3 can be square or circular. In one example, the hole 3 is circular with a diameter of 100 mm. During the screening process, the circular hole 3 can avoid material retention or displacement problems that may be caused by angular or irregular shapes, ensuring that the master alloy ingot can pass through smoothly. At the same time, compared with rectangular or square holes, the circular hole 3 has better flowability and can effectively prevent the master alloy ingot from clogging during the screening process.

[0042] The working principle of the hopper for receiving master alloy ingots in this application is as follows:

[0043] like Figures 1 to 4 First, during the casting process of the master alloy, the master alloy ingot formed by casting will be transported to the hopper area by the casting flatcar. The ingot mold will be rotated 90°, and the master alloy ingot inside the ingot mold will fall into the receiving area 11 of the hopper body 1 under the action of gravity. At this time, the size of the master alloy ingot may vary. Some are qualified small-sized ingots, while others may be larger and exceed the required qualified size.

[0044] When the master alloy ingot falls into the hopper body 1, it first contacts the receiving plate 2 at the top of the hopper and then impacts the first screen plate 21 and the second screen plate 22 on the receiving plate 2. The master alloy ingot breaks into appropriately sized pieces after the impact. Both the first screen plate 21 and the second screen plate 22 have circular holes 3, each 100mm in size. Larger master alloy ingots (greater than 100mm) break upon impact with the screen plates, some fall into the hopper along the inclined surface of the receiving plate 2, while others remain unbroken on the screen plates. These unbroken ingots require manual or mechanical crushing to reduce their size and meet subsequent process requirements. Smaller master alloy ingots (less than 100mm) are smaller and meet the qualification standards, allowing them to directly pass through the holes 3 in the screen plates into the receiving area 11 of the hopper body 1, ready for the next processing stage.

[0045] After screening, qualified master alloy ingots are collected in the receiving area 11. The guide plate 120 of the discharge area 12 is inclined relative to the bottom of the receiving area 11. On the one hand, it ensures that the master alloy ingots falling into the receiving area 11 are not easily scattered outside the hopper. On the other hand, it allows the master alloy ingots to flow naturally into the required area through the discharge area 12 by gravity. The baffles 121 on both sides of the guide plate 120 can make the master alloy ingots flow along a predetermined trajectory, avoiding lateral overflow or uneven distribution of the master alloy ingots, thereby improving the accuracy and efficiency of production.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
