[0002] Powder metallurgy is the process of producing metal powder or using metal powder as raw material, forming and sintering it to manufacture metal materials, composite materials, and various types of products. Powder metallurgy includes both powder making and product manufacturing. While powder making is primarily a metallurgical process, powder metallurgy products often go far beyond the scope of materials and metallurgy, often involving multiple disciplines. Modern metal powder 3D printing technology, in particular, integrates mechanical engineering, CAD, reverse engineering, layered manufacturing, CNC, materials science, and laser technology, making powder metallurgy product technology a modern, multidisciplinary, and comprehensive technology.

[0003] Currently, powder production requires the use of powder screening equipment. This equipment can screen different types of powders, and after screening, the powders are loaded into a barrel for later processing. Metal powder that does not meet the requirements after screening by the powder screening equipment is called powder residue. To recycle and reuse the powder residue and improve its utilization rate, this powder residue needs to be collected and stored. Due to the wide variety of alloy metal powders, and the differences in customer-required product parameters and the content of various metals, many types of powder residue are produced. Traditionally, powder residues of the same type are manually collected and packed into ton bags for storage in a warehouse. This collection process is prone to high labor costs, material waste, and the mixing of different powder residues. It also leads to a poor workshop environment and the leakage of powder residue.

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] During the production process of alloy powder, the yield is generally between 30% and 70% due to factors such as different product specifications, molding processes, cooling methods, and screening processes. The remaining waste alloy powder is called slag powder or powder slag. The output of slag powder is very large. Due to the different uses of alloy powder and the wide variety of product specifications, the types and quantities of slag powder in the production process are extremely large. Therefore, an automatic collection and storage system for powder slag has been developed. Through packaging and storage, it can be taken out from the storage system and then smelted to produce alloy powder, aiming to improve the utilization rate of powder slag.

[0022] Please also refer to Figures 1 to 6, an automatic collection and storage system for recycled powder provided by the present invention is now described. The automatic collection and storage system for recycled powder includes a storage device 1, a conveying pipe 2, a negative pressure suction device 3, an identification terminal 4 and a control terminal 5. The storage device 1 has multiple spaces for independently accommodating powder residues, and the multiple spaces are respectively used to store different types of powder residues. A discharge port 11 is provided at the bottom of each of the multiple spaces; there are multiple conveying pipes 2, one end of which is connected to the multiple spaces of the storage device 1, and the multiple conveying pipes 2 are respectively used to convey powder residues to the multiple spaces, and the multiple conveying pipes 2 are respectively provided with valves suitable for controlling the on-off of powder residues in the conveying pipes 2 (gate valves, rotary valves, butterfly valves, etc. in the prior art are used, which are electrically controlled and not shown in the figure); one end of the negative pressure suction device 3 is used to connect to the multiple spaces of the storage device 1. The powder screening device 6 has the other end used to connect to one end of a conveying pipe 2 away from the storage device 1. The negative pressure suction device 3 is suitable for conveying powder residue from the inside of the powder screening device 6 to one of the conveying pipes 2. The powder residue output end of the negative pressure suction device 3 can be connected to different ends of the conveying pipes 2; the identification terminal 4 is connected to the powder screening device 6 and displays powder residue variety information; the control terminal 5 is electrically connected to the valves of multiple conveying pipes 2 respectively and is used to control the opening or closing of multiple valves respectively. The control terminal 5 is electrically connected to the identification terminal 4 and is suitable for receiving information from the identification terminal 4, and controlling the corresponding valve to open according to the information, so that the powder residue is input into the corresponding conveying pipe 2 and then stored in the storage device 1.

[0023] The present invention provides an automatic collection and storage system for recycled powder. Compared with the prior art, different types of powder residue can be stored separately through a storage device 1, and powder residue can be transported to the interior of the storage device 1 through a conveying pipe 2. Valves are respectively provided inside the multiple conveying pipes 2; a negative pressure suction device 3 can be used to transport powder residue from a powder screening device 6 to the conveying pipe 2. By identifying the type of powder residue stored in the terminal 4, the control terminal 5 controls the corresponding valve to open according to the type of powder residue information, so that different types of powder residue are input into their corresponding conveying pipes 2, and then stored in different spaces of the storage device 1, thereby achieving classified storage. The present invention provides an automatic collection and storage system for recycled powder, which has the technical effect of being able to collect and store the screened powder residue by type, and easily improving the utilization rate of the powder residue.

[0024] The identification terminal 4 in this embodiment has a display and a setting module, which can adopt existing technology and can set and display the type information of the powder residue to be output (which can be set manually). The control terminal 5 can be used to compare and analyze the powder residue type information displayed by the identification terminal 4. The control terminal 5 can always receive the powder residue type information currently displayed by the identification terminal 4. The valve information inside each conveying pipeline 2 is inconsistent, that is, one type of powder residue type information corresponds to one valve, that is, the opening and closing of the valve can be controlled by the control terminal 5. When the powder residue type information and the valve information (such as each valve is provided with a number) correspond to or are the same as each other, the control terminal 5 controls the valve to open, and at the same time controls the negative pressure suction device 3 to connect to the conveying pipeline 2 corresponding to the valve, so that the powder residue can be transported to the inside of the conveying pipeline 2. Through the falling or flowing of its own weight, the powder residue can finally fall into the space at the corresponding position, so that the powder residue of this type is stored correspondingly in the corresponding space, thereby realizing the classified storage of the powder residue. There will be no manual sorting during the entire process, which saves manual operation and improves the efficiency of powder and slag classification and storage. At the same time, the classification, transportation and storage processes are all closed operations, which can effectively reduce pollution to the environment.

[0025] The control terminal 5 is arranged near the storage device 1, in a position convenient for manual operation and observation. The control terminal 5 and the identification terminal 4 can be electrically connected via a wire harness or wirelessly connected via a wireless communication module (which is conventional technology).

[0026] In some embodiments, see Figures 1 to 6 The storage device 1 includes a plurality of tanks 12 arranged in a matrix, with adjacent tanks 12 positioned close together to form a space within the tanks 12. Each tank 12 has a feed port 13 at the top and a discharge port 11 at the bottom. Each tank 12 has a display screen 14 on its outer wall, which displays information about the powder residue storage capacity and product specifications within the tank 12. The tanks 12 are positioned vertically and are used to store or accumulate powder residue. The powder residue enters through the feed port 13 and is discharged through the discharge port 11. Information about the type and storage capacity of the powder residue within the tank 12 can be viewed through the display screen 14, thereby clearly indicating the level of the powder residue within the tank 12.

[0027] In some embodiments, see Figures 1 to 6The negative pressure suction device 3 includes a suction machine having a suction port and a discharge port. The suction port is connected to the powder screening device 6 through a pipe 31, and the discharge port is connected to one end of one of the conveying pipes 2 through a pipe 31. The position of the pipe 31 connected to the discharge port can be adjusted to adapt to communication with conveying pipes 2 at different positions. The suction machine in this embodiment is a prior art that can perform negative pressure suction on powder residue. A negative pressure suction device can be used to convey the powder residue by creating a negative pressure environment, and then the powder residue can be transported from the powder screening device 6 to the interior of the conveying pipe 2. By moving the pipe 31, it can be docked and connected with the conveying pipes 2 at different positions, so that different types of powder residue can fall into different conveying pipes 2, thereby realizing classified storage of the powder residue.

[0028] Preferably, the above-mentioned pipelines 31 all adopt existing technologies, and after forming a negative pressure environment, no flattening, deformation, etc. will occur, thereby realizing the transportation of powder residue.

[0029] In some embodiments, see Figures 1 to 6 The automatic collection and storage system for recycled powder also includes a mobile cart 7. A pipe 31 connected to the discharge port and near the conveying pipe 2 is connected to the mobile cart 7. The mobile cart 7 is used to move the pipe 31 to adjust its position and connect one end to the conveying pipe 2 at different locations. The mobile cart 7 can move the pipe 31. The control terminal 5 is also electrically connected to the mobile cart 7 and can control parameters such as the movement position, start-up, and speed of the mobile cart 7, thereby enabling the pipe 31 to be connected to the conveying pipe 2 at different locations.

[0030] In this embodiment, the delivery pipe 2 is arranged in an inclined or vertical configuration, with its lower end connected to the tank 12 and its upper end facing upward, facilitating docking or plugging with the pipe 31. A valve is located near the upper end of the delivery pipe 2. Only when the valve is open can powder residue enter the delivery pipe 2. When the valve is closed, powder residue cannot be transported or fall into the delivery pipe 2, thereby preventing the misfeeding of powder residue. The upper ends of the multiple delivery pipes 2 are arranged in a straight line with equal spacing (defined as being arranged in a row). By controlling the movement distance of the movable carriage 7, the pipe 31 can be docked and connected with the delivery pipes 2 at different positions. The movement path of the movable carriage 7 is parallel to the arrangement direction of the multiple delivery pipes 2, so that the pipe 31 moves above the upper ends of the multiple delivery pipes 2. When two rows of delivery pipes 2 are provided, the movable carriage 7 can be manually controlled to move (in a direction perpendicular to the arrangement direction of the multiple delivery pipes 2) to the delivery pipe 2 near the other row. The movement of the movable carriage 7 along the arrangement direction of the multiple delivery pipes 2 can be achieved by the movable carriage 7 itself.

[0031] In order to fix the pipe 31 and adjust the posture of the pipe 31 or the powder discharge position, in some embodiments, refer to Figures 1 to 6The upper end of the mobile trolley 7 is connected to a rotating platform 8, and the upper end of the rotating platform 8 is connected to a clamping member 9. The rotating platform 8 is used to drive the clamping member 9 to rotate in a circular direction. The clamping member 9 is used to clamp and fix the pipe 31. The upper end of the clamping member 9 forms an enclosure for surrounding and clamping the pipe 31. The width of the enclosure cavity can be adjusted to adapt to clamping and fixing pipes 31 of different diameters. The rotating platform 8 is a prior art that can rotate in a circular direction. It is electrically or wirelessly connected to the control terminal 5. By manipulating the control terminal 5, the rotation of the rotating platform 8 can be controlled, thereby adjusting the angle of the clamping member 9 and the arrangement direction or position of the pipe 31, and further adjusting the position of the powder residue discharged from the pipe 31 and the position of the connection with the conveying pipe 2.

[0032] The above-mentioned clamping member 9 can adopt existing technology and has a structure similar to that of pliers, which can realize the clamping and fixing of the pipe 31. The clamping width (that is, the width of the surrounding cavity) is adjustable, thereby meeting the clamping and fixing requirements for pipes 31 of different diameters.

[0033] In some embodiments, see Figures 1 to 6 A driver 71 is provided at the bottom of the mobile trolley 7. The driver 71 is used to drive the mobile trolley 7 to move. The driver 71 is electrically connected to the control terminal 5 and its operation is controlled by the control terminal 5. The driver 71 is a drive motor, and its power output end is connected to at least one gear of the mobile trolley 7 through power transmission. Therefore, the power output of the driver 71 can drive the mobile trolley 7 to move. The mobile trolley 7 can only move in a straight line along the layout direction of the multiple conveying pipes 2, and cannot achieve turning operations. If such operations are to be achieved, the movement and turning operations of the mobile trolley 7 can be manually controlled.

[0034] In some embodiments, see Figures 1 to 6 , multiple conveying pipes 2 are arranged close to each other at one end away from the storage device 1, and a first partition wall 10 and a second partition wall 110 are arranged horizontally above the storage device 1. The height of the first partition wall 10 is lower than the height of the second partition wall 110. Multiple conveying pipes 2 pass through the first partition wall 10 and the second partition wall 110. One side of the second partition wall 110 can be detachably connected (such as Figure 4-5 The first and second partition walls 10 and 110 are connected by connectors and have a support plate 120. The support plate 120 and the second partition wall 110 are located in the same horizontal plane, and the mobile cart 7 travels on the upper end of the support plate 120. In this embodiment, the first and second partition walls 10 and 110 are used to secure the conveying pipe 2 and can be fixed inside the workshop. To facilitate the installation of the mobile cart 7, the support plate 120 is installed on the side of the second partition wall 110, allowing the mobile cart 7 to move on the support plate 120. The support plate 120 is detachably connected to the second partition wall 110, meaning it can be removed when not in use.

[0035] In some embodiments, see Figures 1 to 6 A lifting column 130 is connected between the second partition wall 110 and the first partition wall 10. The lifting column 130 is vertically arranged with its upper end connected to the bottom end of the second partition wall 110 and its lower end connected to the upper end of the first partition wall 10. The height of the second partition wall 110 is adjusted by means of the lifting column 130. In this embodiment, the first partition wall 10 is connected to a fixed object inside the workshop, while the second partition wall 110 can be connected to the upper end of the lifting column 130 without the workshop fixed object. By controlling the lifting column 130, the height of the second partition wall 110 can be controlled and adjusted, thereby fixing the conveying pipes 2 of different lengths. A plurality of through holes are provided on both the first partition wall 10 and the second partition wall 110. These through holes are used to facilitate the passage of the conveying pipe 2 to achieve the fixing of the conveying pipe 2.

[0036] Preferably, a lifting column 130 is also provided at the lower end of the support plate 120. The upper end of the lifting column 130 is connected to the support plate 120, and the lower end can be connected to the upper end of the first partition wall 10. The lifting column 130 serves to fix and support the support plate 120. The lifting column 130 can be arranged in an inclined shape as long as it can provide support for the support plate 120.

[0037] In some embodiments, see Figures 1 to 6 A weighing assembly 15 is connected to the interior of the tank body 12. The weighing assembly 15 is used to weigh the powder residue that falls into the tank body 12. The weighed powder residue falls below the weighing assembly 15 and is located inside the tank body 12. A frame 16 is provided on the periphery of the tank body 12. The frame 16 is used to fix the tank body 12 and maintain the tank body 12 in an upright position. The weighing assembly 15 can be installed inside the tank body 12 using existing technology to achieve one or more weighing of the powder residue that falls into the tank body 12. The display screen 14 can display the information of the one or more weighings for the viewer to see.

[0038] Preferably, the weighing assembly 15 includes a weighing sensor, a weighing hopper and a controller. The controller can control the automatic unloading of the weighing hopper. The weighing hopper is arranged in the tank body 12 and is located in the middle vertically. It can receive the powder residue falling into the tank body 12. The weighing sensor can weigh the weighing hopper and transmit the weight signal to the display screen 14. The controller and the display screen 14 are installed on the outer wall of the tank body 12 and can display the weighing information. After weighing, the automatic unloading of the weighing hopper can be achieved by operating the controller, so that the powder residue can fall into the bottom of the tank body 12, thereby achieving a single weighing of the powder residue. If re-weighing is required, the last operation can be repeated. The display screen 14 can record the information of each weighing.

[0039] In some embodiments, see Figures 1 to 6The control terminal 5 includes a PLC controller and a receiving module, a judgment module, a control module, a display module, and an alarm module electrically connected to the PLC controller. The receiving module is adapted to receive information from the identification terminal 4, the judgment module is adapted to determine whether the information from the identification terminal 4 is identical to the corresponding valve information, the control module is adapted to control the corresponding valve to open or close, the display module is adapted to display the information from the identification terminal 4, and the alarm module issues an alarm signal when the information from the identification terminal 4 is inconsistent with the valve information. The receiving module, judgment module, control module, display module, and alarm module can all be existing products and can implement functions such as receiving information, judging and analyzing the information, controlling the opening and closing of the valve, displaying the information, and providing an alarm if an analysis error occurs.
