Description

Technical Field

[0001] This utility model relates to the field of aluminum-based boron carbide production technology, and in particular to an integrated weighing, mixing and loading device for aluminum-based boron carbide production. Background Technology

[0002] Aluminum-based boron carbide composites play a crucial role in aerospace, defense, and nuclear industries due to the high hardness and wear resistance of boron carbide and the good processability of aluminum matrix. However, their production process faces many challenges, and existing equipment is unable to meet the requirements of high-precision and high-efficiency production.

[0003] Traditional equipment has significant shortcomings in the material mixing and conveying stages. Because boron carbide particles and aluminum powder have similar densities but significantly different flowability, and boron carbide is extremely hard, traditional mixing equipment not only struggles to achieve uniform mixing but also easily leads to particle agglomeration and stratification, greatly affecting the mechanical properties of the composite material. Furthermore, the high hardness of the boron carbide particles causes severe erosion and wear on the equipment's inner walls, resulting in high maintenance costs. In the loading process, the traditional step-by-step operation is cumbersome, requiring multiple material transfers, which is not only inefficient but also increases the risk of impurity contamination. Moreover, it is difficult to ensure uniform material distribution during loading, leading to uneven density in the billet. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art where aluminum-based boron carbide composite materials are prone to particle agglomeration and delamination, as well as the cumbersome traditional distributed operation process, high equipment maintenance costs, and the risk of impurity contamination. Therefore, this invention proposes an integrated weighing, mixing, and loading equipment for aluminum-based boron carbide production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated weighing, mixing and loading device for aluminum-based boron carbide production includes a storage tank and a sliding base. The top of the storage tank is provided with a cover, which is used to protect the aluminum-based boron carbide composite material inside the storage tank.

[0007] The storage tank is equipped with a mixing component in the middle, which is used to mix the material in the storage tank before it is discharged; the sliding base is equipped with a cylinder, which is used to push the storage tank to discharge material corresponding to the discharge port; the bottom of the sliding base is equipped with a weighing module, which is used to weigh the amount of material remaining in the storage tank.

[0008] In some embodiments, the mixing assembly includes an auger shaft and a drive motor, with a gap between the blades of the auger shaft and the inner wall of the storage tank; a sampling port is provided on one side of the storage tank, which is used to sample and detect the uniformity of aluminum-based boron carbide composite material at different heights inside the storage tank.

[0009] The storage tank is equipped with a slider at the bottom, and the top of the sliding base has an opening. A cylinder is provided on one side of the opening. The telescopic end of the cylinder is fixedly connected to the storage tank, and the cylinder drives the storage tank to move horizontally.

[0010] In some embodiments, the bottom end of the storage tank is slidably connected to the opening at the top of the sliding base; the opening is provided with a limiting slide rail, and the slider and the limiting slide rail cooperate accordingly, so that the limiting slide rail and the slider provide movement limit for the storage tank.

[0011] In some embodiments, the weighing module is provided with a support at the bottom, and the opening and the weighing module are provided with a material discharge port that runs vertically through the top and bottom; the weighing module is provided with a pusher assembly at the bottom, which is used to squeeze and disturb the material in the storage tank, thereby breaking the interlocking property between the aluminum-based boron carbide composite material particles.

[0012] In some embodiments, the pusher assembly includes a connecting frame and an electric pusher rod. The telescopic end of the electric pusher rod is provided with a support ring, and the top of the support ring is provided with an insert rod. The diameter of the support ring is smaller than the material discharge port. The electric pusher rod drives the insert rod to move up and down, and the insert rod squeezes and disturbs the material at the bottom of the storage tank.

[0013] In some embodiments, the surfaces of the support ring and the insertion rod are both curved.

[0014] In some embodiments, the insertion rod is configured as a two-section rod that can be detached from the top and bottom, including an upper rod and a lower rod, the upper rod and the lower rod being threadedly connected, for replacing the upper rod with different diameters and for replacing the upper rod.

[0015] Compared with the prior art, this utility model provides an integrated weighing, mixing and loading device for aluminum-based boron carbide production, which has the following beneficial effects.

[0016] 1. This utility model utilizes the auger shaft in the mixing assembly to generate forced shearing force through spiral motion, which can break up the agglomerates of boron carbide particles. During the upward conveying of materials, the combined axial and radial motion ensures that the high-density boron carbide particles and aluminum powder are fully mixed, avoiding the "aluminum on top, boron on the bottom" stratification phenomenon. This significantly improves the mixing uniformity of aluminum-based boron carbide composite materials and ensures the stability of the product's mechanical properties.

[0017] 2. This utility model integrates weighing, mixing, and loading functions into one unit, avoiding multiple material transfers in traditional step-by-step operations, reducing process connection time, and lowering the risk of impurity contamination. The storage tank is driven horizontally by a cylinder, allowing for quick alignment with the discharge port for loading, simplifying the operation process and improving production efficiency.

[0018] 3. This utility model utilizes the push-top assembly's insert rod to repeatedly move up and down at the bottom of the storage tank, providing compression and disturbance to the material, disrupting the interlocking between particles, and causing the arch frame to collapse and fall quickly, preventing material accumulation and blockage. Compared to the method of forced feeding using a screw conveyor in reverse, this effectively reduces frictional wear between the screw conveyor and the inner wall of the storage tank, extending the equipment's service life.

[0019] 4. This utility model allows for intermittent sampling and inspection of materials at different heights during the mixing process via a sampling port and sampling device on one side of the storage tank. Mixing can be interrupted when the material uniformity meets the standard, eliminating the need for a fixed mixing time and avoiding time waste caused by over-mixing. This enables flexible adjustment of the production rhythm based on the actual state of the materials, thereby improving production efficiency.

[0020] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0032] 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.

[0033] Reference Figure 1-9 An integrated weighing, mixing, and loading device for aluminum-based boron carbide production includes a storage tank 1 and a sliding base 2. The top of the storage tank 1 is provided with a cover 101, and the cover 101 is provided with a feed inlet 1011. A mixing component 3 is provided in the middle of the storage tank 1. The mixing component 3 includes an auger shaft 301 and a drive motor 302 located in the middle of the cover 101. When the drive motor 302 is powered on and started, it drives the auger shaft 301 to rotate, thereby mixing the material in the storage tank 1.

[0034] The storage tank 1 has a slider 103 at its bottom, and the top of the sliding base 2 has an opening. A slot 201 is formed on one side of the opening, and a cylinder 4 is installed inside the slot 201. The telescopic end of the cylinder 4 is fixedly connected to the storage tank 1, and the cylinder 4 drives the storage tank 1 to move horizontally. The bottom end of the storage tank 1 is adapted to the opening; the bottom end of the storage tank 1 is slidably connected to the opening. The storage tank 1 has a bucket-shaped structure, which facilitates the downward collection and discharge of the composite material inside the storage tank 1.

[0035] Specifically, the opening is provided with a limiting slide rail 202, and the slider 103 is correspondingly engaged with the limiting slide rail 202.

[0036] The bottom of the sliding base 2 is equipped with a weighing module 5, which is used to weigh the amount of remaining material in the storage tank 1. The bottom of the weighing module 5 is equipped with a bracket 501, and the opening and the weighing module 5 are provided with a vertically penetrating discharge port 203, which is located at the end away from the cylinder 4.

[0037] In this invention, a sliding base 2 supports the storage tank 1. A weighing module 5 at the bottom of the sliding base 2 carries the sliding base 2, the storage tank 1, the mixing component 3, and the aluminum-based boron carbide composite material inside the storage tank 1. The weighing module 5 is a mature weighing device in the prior art. Before the aluminum-based boron carbide composite material is introduced into the storage tank 1, the weight detected by the weighing module 5 is recorded as 0, meaning the weight of all other components on top of the weighing module 5 is ignored.

[0038] During use, the aluminum-based boron carbide composite material is stored in the storage tank 1. The top of the storage tank 1 is sealed by the cover 101 to prevent the aluminum powder from oxidizing upon contact with air or the boron carbide particles from absorbing moisture or impurities. The sealing effect of the cover 101 reduces the interference of the external environment on the storage quality of the aluminum-based boron carbide composite material.

[0039] Before the aluminum-based boron carbide composite material in storage tank 1 is conveyed outward for loading, because the aluminum-based boron carbide composite material powder has the characteristics of high-hardness particles mixed with metal powder, and its density is close to that of aluminum powder but its flowability is significantly different, the material is first conveyed upward by the drive motor 302 in the mixing component 3, which drives the auger shaft 301 to continuously convey the material at the bottom of storage tank 1. During this process, the auger shaft 301 generates a forced shearing force on the material during its spiral motion, which can break up the agglomeration of boron carbide particles. At the same time, through the combined axial and radial motion, the high-density boron carbide particles and aluminum powder are continuously mixed during the conveying process, avoiding the "aluminum on top and boron on the bottom" stratification phenomenon caused by gravity settling.

[0040] After the mixing component 3 has mixed the composite material in the storage tank 1, for example, after the drive motor 302 has started and reached the preset mixing time, the composite material is then conveyed outward for loading. Specifically, under the limiting action of the limiting slide rail 202 on the slider 103, the cylinder 4 drives the storage tank 1 to move horizontally along the limiting slide rail 202, so that the bottom of the storage tank 1 moves from one end of the opening to the other end. At this time, the bottom of the storage tank 1 corresponds to the discharge port 203. Below the discharge port 203 is the composite material receiving area, where the uniformly mixed aluminum-based boron carbide composite material is loaded. After loading is completed, the cylinder 4 drives the storage tank 1 to move horizontally along the limiting slide rail 202 to reset. The cylinder 4 serves as a power element, which can also be a hydraulic cylinder.

[0041] As the aluminum-based boron carbide composite material in storage tank 1 is discharged outward, the value monitored by the weighing module 5 will become lower and lower. When the preset value is reached, the material in storage tank 1 will be replenished through the inlet 1011.

[0042] In practical use, due to the high hardness of the aluminum-based boron carbide composite material and the large frictional force between particles, the material may form a relatively stable arch under gravity; or when agglomeration occurs, it may directly block the bottom of the bucket-shaped storage tank 1, interfering with the normal falling of the material. Although the auger shaft 301 can be driven downward by the drive motor 302 in the mixing component 3 to move the aluminum-based boron carbide composite material downward, the high hardness of the aluminum-based boron carbide composite material will cause excessive frictional wear of the auger shaft 301 in actual use, seriously affecting the service life of the auger shaft 301. Therefore, the following improvements are made:

[0043] A pusher assembly 6 is provided at the bottom of the weighing module 5. The pusher assembly 6 includes a connecting frame 601. An electric push rod 602 is provided on the connecting frame 601. A support ring 603 is provided at the telescopic end of the electric push rod 602. An insert rod 604 is provided at the top of the support ring 603. The diameter of the support ring 603 is smaller than that of the material discharge port 203.

[0044] In the initial state, the top of the insertion rod 604 is lower than the lower surface of the storage tank 1. When the aluminum-based boron carbide composite material is discharged and conveyed outward through the discharge port 203 inside the storage tank 1,

[0045] The electric push rod 602 in the push assembly 6 drives the support ring 603 and the insertion rod 604 to move up and down, causing the insertion rod 604 to move up and down repeatedly at the bottom of the storage tank 1. When the material in the storage tank 1 is discharged downward, it provides a squeezing and disturbance effect on the material in the storage tank 1, thereby breaking the interlocking property between the aluminum-based boron carbide composite material particles, causing the formed arch frame to quickly become unstable, collapse and fall, thus avoiding excessive wear between the auger shaft 301 and the inner wall of the storage tank 1.

[0046] The surfaces of the support ring 603 and the insertion rod 604 are curved, which will not cause jamming with the aluminum-based boron carbide composite material. At the same time, depending on the use needs, the insertion rod 604 can be set as a double-section rod that can be detached from the top and bottom. The double-section rod includes an upper rod and a lower rod. The lower rod is fixedly connected to the support ring 603, and the upper rod is threadedly connected to the lower rod. This is used to replace the upper rod with one of different diameters, which can improve the extrusion and disturbance strength of the material at the bottom of the storage tank 1. When the upper rod is worn, it is easy to replace the upper rod.

[0047] As a supplement, since the interval between the material being discharged from storage tank 1 is not fixed, the storage time of the material is also not fixed. The degree of stratification of the composite material in storage tank 1 is not uniform. If the auger shaft 301 is rotated for a preset time by drive motor 302 before each discharge of composite material from storage tank 1, it will affect the efficiency of the composite material discharge. Therefore, a sampling port 102 is provided on one side of storage tank 1, and the blades of auger shaft 301 are left with a gap between them and the inner wall of storage tank 1.

[0048] When the material in the storage tank 1 is mixed and stirred by the auger shaft 301, the sampling component 7 is intermittently inserted into the storage tank 1 through the sampling port 102 to sample and check the compound material. When there is no obvious difference in the uniformity of the compound material at different heights in the storage tank 1, the power supply to the drive motor 302 is interrupted, and the cylinder 4 drives the storage tank 1 to discharge material corresponding to the discharge port 203.

[0049] In one embodiment of the sampling component 7, the sampling component 7 includes a sampling rod 701, on which a sampling groove 702 is provided. The sampling rod 701 is used to extend into the storage tank 1 through the sampling port 102. The sampling rod 701 is quickly inserted into the storage tank 1 through the sampling port 102, so that the composite material at different heights in the storage tank 1 enters the sampling rod 701 through the sampling groove 702 for sampling.
