Description

Technical Field

[0001] This invention belongs to the field of powder metallurgy technology, and more specifically, relates to an automatic collection and storage system for recycled powder. Background Technology

[0002] Powder metallurgy is a process technology that involves producing metal powders or using metal powders as raw materials, followed by forming and sintering to manufacture metallic materials, composite materials, and various types of products. Powder metallurgy includes both powder preparation and product manufacturing. Powder preparation is primarily a metallurgical process, while powder metallurgy products often extend far beyond the scope of materials and metallurgy, frequently involving multidisciplinary technologies. In particular, modern metal powder 3D printing technology integrates mechanical engineering, CAD, reverse engineering, layered manufacturing, CNC technology, materials science, and laser technology, making powder metallurgy product technology a modern comprehensive technology that spans even more disciplines.

[0003] Currently, powder screening equipment is required during powder production. This equipment can screen different types of powders, and the screened powder is then loaded into a hopper for later processing. Metal powder that does not meet the requirements after screening is called slag. To ensure the slag can be recycled and reused, and to improve its utilization rate, it needs to be collected and stored. Due to the wide variety of alloy metal powders and the differences in product parameters and metal content required by customers, many types of slag are formed. Traditionally, the same type of slag is manually collected and stored in ton bags in a warehouse. This collection process easily leads to high labor costs, material waste, and mixing of different slag types, while also causing a poor workshop environment and slag leakage.

[0004] Therefore, it is necessary to improve the current methods of collecting and storing powder residue so that different types of powder residue can be loaded into different buckets for classified collection and storage, thereby preventing environmental pollution and powder residue leakage in the workshop. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic collection and storage system for recycled powder, which aims to solve the technical problems in the existing technology where the collection and storage of sieved powder residue is done manually and then packed into ton bags for storage in warehouses. This process involves a large amount of labor, mixed powder residue, poor workshop environment, and easy leakage of powder residue.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an automatic collection and storage system for recycled powder, comprising:

[0007] The storage device has multiple independent spaces for holding powder residue, and each of the multiple spaces is used to store different types of powder residue. Each of the multiple spaces is provided with a discharge port at the bottom.

[0008] There are multiple conveying pipes, one end of which is connected to multiple spaces of the storage device. Each of the multiple conveying pipes is used to convey powder and slag into the multiple spaces respectively. Each of the multiple conveying pipes is equipped with a valve suitable for controlling the on / off of the powder and slag inside the conveying pipe.

[0009] A negative pressure suction device has one end connected to a powder screening device and the other end connected to one end of a conveying pipe away from the storage device. The negative pressure suction device is adapted to convey powder residue from inside the powder screening device into one of the conveying pipes. The powder residue output end of the negative pressure suction device can be connected to different ends of the conveying pipes.

[0010] The identification terminal is connected to the powder screening equipment and displays information about the powder residue type.

[0011] The control terminal is electrically connected to the valves of the multiple conveying pipelines and is used to control the opening or closing of the multiple valves respectively. The control terminal is electrically connected to the identification terminal and is adapted to receive the identification terminal information and control the corresponding valve to open according to the information, so that the powder and slag are input into the corresponding conveying pipeline and then stored in the storage device.

[0012] In one possible implementation, the storage device includes multiple tanks arranged in a matrix, with adjacent tanks placed close together, forming a space inside each tank. Each tank has a feed inlet at its top and a discharge outlet at its bottom. Each tank has a display screen on its outer wall, displaying information on the amount of powder and slag stored inside the tank and product specifications.

[0013] In one possible implementation, the negative pressure suction device includes a suction machine having a suction port and a discharge port. The suction port is connected to a powder screening device via a pipe, and the discharge port is connected to one end of one of the conveying pipes via a pipe. The position of the pipe connected to the discharge port is adjustable to adapt to connection with conveying pipes at different positions.

[0014] In one possible implementation, an automatic collection and storage system for recycled powder further includes a mobile trolley, with the pipe connected to the discharge port and positioned near the conveying pipe. The mobile trolley is used to move the pipe to adjust its position and connect one end to the conveying pipe at different locations.

[0015] In one possible implementation, the upper end of the mobile trolley is connected to a rotating platform, and the upper end of the rotating platform is connected to a snap-fit ​​component. The rotating platform is used to drive the snap-fit ​​component to rotate circumferentially, and the snap-fit ​​component is used to snap-fit ​​and fix the pipe. The upper end of the snap-fit ​​component forms an enclosing cavity for surrounding and snapping the pipe, and the width of the enclosing cavity is adjustable to adapt to snap-fit ​​and fix pipes of different diameters.

[0016] In one possible implementation, a driver is provided at the bottom of the mobile vehicle, the driver is used to drive the mobile vehicle to move, and the driver is electrically connected to the control terminal and its operation is controlled by the control terminal.

[0017] In one possible implementation, the ends of the multiple conveying pipes away from the storage device are arranged close to each other. A first partition wall and a second partition wall are arranged horizontally above the storage device. The height of the first partition wall is lower than that of the second partition wall. The multiple conveying pipes pass through the first partition wall and the second partition wall. A support plate is detachably connected to one side of the second partition wall. The support plate and the second partition wall are located in the same horizontal plane. The mobile trolley travels on the upper part of the support plate.

[0018] In one possible implementation, a lifting column connects the second partition wall and the first partition wall. The lifting column is vertically arranged with its upper end connected to the bottom of the second partition wall and its lower end connected to the upper end of the first partition wall. The height of the second partition wall is adjusted by means of the lifting column.

[0019] In one possible implementation, a weighing component is connected inside the tank body to weigh the powder and slag falling into the tank body, and the weighed powder and slag fall below the weighing component; a frame is provided on the outer periphery of the tank body to fix the tank body and keep the tank body vertical.

[0020] In one possible implementation, the control terminal 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 the identification terminal information, the judgment module is adapted to determine whether the identification terminal information is the same as the corresponding information of the valve, the control module is adapted to control the corresponding valve to open or close, the display module is adapted to display the identification terminal information, and the alarm module issues an alarm signal when the identification terminal information is different from the valve information.

[0021] The beneficial effects of the automatic collection and storage system for recycled powder provided by this invention are as follows: Compared with the prior art, the automatic collection and storage system for recycled powder of this invention includes a storage device, a conveying pipeline, a negative pressure suction device, an identification terminal, and a control terminal. The storage device has multiple independent spaces for accommodating powder residue, each space being used to store different types of powder residue, and each space has a discharge port at its bottom. Multiple conveying pipelines are used to convey powder residue to the corresponding spaces. Each conveying pipeline is equipped with a valve suitable for controlling the flow of powder residue within it. The negative pressure suction device conveys powder residue from inside a powder screening device to one of the conveying pipelines. The powder residue output end of the negative pressure suction device can be connected to different conveying pipelines. The pipeline end is connected, and the identification terminal displays information about the powder and slag type. The control terminal is electrically connected to multiple valves and is used to control the opening or closing of multiple valves. The control terminal is electrically connected to the identification terminal and is suitable for receiving information from the identification terminal. Based on this information, it controls the corresponding valve to open so that the powder and slag are input into the corresponding conveying pipeline and then stored in the storage device. This solves the technical problems of manually collecting and storing the screened powder and slag into ton bags and storing them in the warehouse, which requires a large amount of labor, results in mixed powder and slag, causes a poor workshop environment, and is prone to leakage. It has the technical effect of collecting and storing the screened powder and slag by type, eliminating manual operation, reducing environmental pollution and powder and slag leakage.

[0031] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0032] During the production of alloy powder, the yield rate 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 residue. The output of slag powder is very large. Because alloy powder has different uses and a wide variety of product specifications, the types and quantities of slag powder produced during the production process are extremely large. Therefore, an automatic collection and storage system for powder residue has been developed. Through separate storage, it can be taken out from the storage system and then melted to produce alloy powder, aiming to improve the utilization rate of powder residue.

[0033] Please refer to the following: Figures 1 to 6The present invention provides an automatic collection and storage system for recycled powder. The automatic collection and storage system for recycled powder includes a storage device 1, conveying pipes 2, a negative pressure suction device 3, an identification terminal 4, and a control terminal 5. The storage device 1 has multiple independent spaces for storing powder residue, each space being used to store different types of powder residue. Each space has a discharge port 11 at its bottom. Multiple conveying pipes 2 are connected at one end to multiple spaces in the storage device 1. Each conveying pipe 2 is used to convey powder residue into its corresponding space. Each conveying pipe 2 is equipped with a valve (using existing gate valves, rotary valves, butterfly valves, etc., electrically controlled, not shown in the figure) suitable for controlling the flow of powder residue within the conveying pipe 2. One end of the negative pressure suction device 3 is used to connect... The powder screening device 6 has one end connected to the other end of a conveying pipe 2 away from the storage device 1. The negative pressure suction device 3 is adapted to convey powder residue from inside the powder screening device 6 into one of the conveying pipes 2. The powder residue output end of the negative pressure suction device 3 can be connected to the ends of different conveying pipes 2. The identification terminal 4 is connected to the powder screening device 6 and displays powder residue type information. The control terminal 5 is electrically connected to the valves of multiple conveying pipes 2 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 adapted to receive information from the identification terminal 4 and control 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.

[0034] This invention provides an automatic collection and storage system for recycled powder. Compared with existing technologies, this system allows for the separate storage of different types of powder residue through a storage device 1. Powder residue is conveyed into the storage device 1 via multiple conveying pipes 2, each equipped with a valve. A negative pressure suction device 3 conveys powder residue from a powder screening device 6 into the conveying pipes 2. By identifying the powder residue type information stored in the terminal 4, the control terminal 5 controls the corresponding valves to open, allowing different types of powder residue to be input into their respective conveying pipes 2 and then stored in different spaces within the storage device 1, achieving classified storage. This automatic collection and storage system for recycled powder provides the technical advantage of being able to collect and store screened powder residue separately by type, easily improving the utilization rate of powder residue.

[0035] The identification terminal 4 in this implementation has a display and a setting module. It can use existing technology to set and display the type information of the powdered slag to be output (which can be set manually). The control terminal 5 can compare and analyze the powdered slag type information displayed by the identification terminal 4. The control terminal 5 can always receive the powdered slag type information currently displayed by the identification terminal 4. The valve information inside each conveying pipe 2 is inconsistent, that is, one type of powdered slag information corresponds to one valve. The control terminal 5 can control the opening and closing of the valve. When the powdered slag type information and the valve information (such as each valve is assigned a number) correspond to each other or are the same, the control terminal 5 controls the valve to open. At the same time, it controls the negative pressure suction device 3 to connect to the conveying pipe 2 corresponding to the valve, so that the powdered slag can be conveyed into the conveying pipe 2. Through gravity falling or flow, the powdered slag can finally fall into the corresponding space, realizing the storage of the powdered slag of the corresponding type in the corresponding space, thereby realizing the classified storage of powdered slag. The entire process eliminates manual sorting, saving manpower and improving the efficiency of powder and slag sorting and storage. At the same time, the closed operation during sorting, transportation and storage effectively reduces environmental pollution.

[0036] The control terminal 5 is located near the storage device 1, in a position that facilitates manual operation and observation. The control terminal 5 and the identification terminal 4 can be electrically connected via a wiring harness or wirelessly connected via a wireless communication module (existing technology).

[0037] In some embodiments, please refer to Figures 1 to 6 The storage device 1 includes multiple tanks 12 arranged in a matrix, with adjacent tanks 12 placed close together. Each tank 12 has an internal space. Each tank 12 has a feed inlet 13 at its top and a discharge outlet 11 at its bottom. Each tank 12 has a display screen 14 on its outer wall, displaying information on the amount of powder and slag stored inside the tank and the product specifications. The tanks 12 are placed vertically and are used to store powder and slag. The powder and slag enter through the feed inlet 13 and exit through the discharge outlet 11. The display screen 14 allows observation of the powder and slag type and storage amount inside the tank 12, thus clearly indicating the powder and slag level.

[0038] In some embodiments, please refer to Figures 1 to 6The negative pressure suction device 3 includes a suction machine with a suction port and a discharge port. The suction port is connected to the powder screening equipment 6 via a pipe 31, and the discharge port is connected to one end of one of the conveying pipes 2 via a pipe 31. The position of the pipe 31 connected to the discharge port is adjustable to adapt to connection with conveying pipes 2 at different positions. The suction machine in this embodiment is an existing technology capable of negative pressure suction of powder and slag. A negative pressure suction device can be used to create a negative pressure environment to transport the powder and slag, thereby allowing the powder and slag to be transported from the powder screening equipment 6 to the inside of the conveying pipe 2. By moving the pipe 31, it can be docked and connected with conveying pipes 2 at different positions, so that different types of powder and slag fall into different conveying pipes 2, thereby achieving classified storage of powder and slag.

[0039] Preferably, the aforementioned pipes 31 all adopt existing technologies, and will not be flattened or deformed after forming a negative pressure environment, thereby enabling the transportation of powder and slag.

[0040] In some embodiments, please refer to Figures 1 to 6 An automatic collection and storage system for recycled powder also includes a mobile trolley 7. A pipe 31 connected to the discharge port and positioned near the conveying pipe 2 is attached to the mobile trolley 7. The mobile trolley 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 trolley 7 can transport the pipe 31. A control terminal 5 is also electrically connected to the mobile trolley 7 and can control parameters such as the movement position, start-up, and speed of the mobile trolley 7, thereby enabling the pipe 31 to dock with the conveying pipe 2 at different locations.

[0041] In this embodiment, the conveying pipe 2 is arranged at an angle or vertically, with its lower end connected to the tank 12 and its upper end facing upwards, facilitating docking or insertion with the pipe 31. The valve is located near the upper end of the conveying pipe 2; when the valve is open, powder and slag can enter the conveying pipe 2, and when the valve is closed, powder and slag cannot be conveyed or fall in, thus preventing incorrect addition of powder and slag. The upper ends of multiple conveying pipes 2 are arranged in a straight line at equal intervals (defined as arranged in a row). By controlling the movement distance of the moving trolley 7, the pipe 31 can be docked and connected with conveying pipes 2 at different positions. The movement path of the moving trolley 7 is parallel to the arrangement direction of the multiple conveying pipes 2, so the pipe 31 moves above the upper ends of the multiple conveying pipes 2. When there are two rows of conveying pipes 2, the moving trolley 7 can be manually controlled to move (along a direction perpendicular to the arrangement direction of the multiple conveying pipes 2) to be close to another row of conveying pipes 2. The movement of the moving trolley 7 along the arrangement direction of the multiple conveying pipes 2 can be achieved by the moving trolley 7 itself.

[0042] To achieve the fixed position of pipe 31 and adjust the orientation of pipe 31 or the discharge position of slag, please refer to the following embodiments. Figures 1 to 6A rotating platform 8 is connected to the upper end of the mobile trolley 7, and a snap-fit ​​component 9 is connected to the upper end of the rotating platform 8. The rotating platform 8 drives the snap-fit ​​component 9 to rotate circumferentially. The snap-fit ​​component 9 is used to snap and fix the pipe 31. The upper end of the snap-fit ​​component 9 forms an enclosing cavity for surrounding and snapping the pipe 31. The width of the enclosing cavity is adjustable to adapt to snapping and fixing pipes 31 of different diameters. This rotating platform 8 is existing technology and can rotate circumferentially. It is electrically or wirelessly connected to the control terminal 5. By operating the control terminal 5, the rotation of the rotating platform 8 can be controlled, thereby adjusting the angle of the snap-fit ​​component 9 and the placement direction or position of the pipe 31. In addition, the position of the powder and slag discharged from the pipe 31 can be adjusted, and the position of docking and connecting with the conveying pipe 2 can be adjusted.

[0043] The aforementioned snap-fit ​​component 9 can be made using existing technology, with a structure similar to pliers, which can snap-fit ​​and fix the pipe 31. The width of its snap-fit ​​(i.e. the width of the surrounding cavity) is adjustable, thus meeting the snap-fit ​​and fixing requirements for pipes 31 of different diameters.

[0044] In some embodiments, please refer to Figures 1 to 6 The bottom of the mobile trolley 7 is equipped with a driver 71, which 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 for power transmission. Thus, the power output of the driver 71 can drive the mobile trolley 7 to move. The movement of the mobile trolley 7 can only be a straight line along the layout direction of the multiple conveying pipes 2, and it cannot perform operations such as turning. If such operations are to be achieved, the movement and turning of the mobile trolley 7 can be controlled manually.

[0045] In some embodiments, please refer to Figures 1 to 6 Multiple conveying pipes 2 are arranged close to each other at their ends furthest from the storage device 1. A first partition wall 10 and a second partition wall 110 are horizontally arranged above the storage device 1. The height of the first partition wall 10 is lower than the height of the second partition wall 110. The multiple conveying pipes 2 all pass through the first partition wall 10 and the second partition wall 110. One side of the second partition wall 110 is detachably connected (e.g., ...). Figure 4-5 A support plate 120 (connected by connectors) is provided, and the support plate 120 and the second partition wall 110 are located on the same horizontal plane. The mobile trolley 7 travels on the upper part of the support plate 120. In this embodiment, the function of the first partition wall 10 and the second partition wall 110 is to fix the conveying pipe 2, which can be fixed inside the workshop. To facilitate the installation of the mobile trolley 7, a support plate 120 is provided on the side of the second partition wall 110, so that the mobile trolley 7 can move on the support plate 120. The support plate 120 and the second partition wall 110 are detachably connected, that is, the support plate 120 can be removed when not in use.

[0046] In some embodiments, please refer to Figures 1 to 6 A lifting column 130 connects the second partition wall 110 to the first partition wall 10. The lifting column 130 is vertically arranged, with its upper end connected to the bottom 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 using the lifting column 130. In this embodiment, the first partition wall 10 is connected to fixed objects inside the workshop, while the second partition wall 110 can be connected to the upper end of the lifting column 130 without the need for workshop fixed objects. By controlling the lifting column 130, the height of the second partition wall 110 can be controlled and adjusted, thereby enabling the fixing of conveying pipes 2 of different lengths. Multiple through holes are provided on both the first partition wall 10 and the second partition wall 110 to facilitate the passage of the conveying pipes 2 for fixing.

[0047] 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 set at an angle, as long as it can provide support for the support plate 120.

[0048] In some embodiments, please refer to Figures 1 to 6 A weighing assembly 15 is connected inside the tank body 12. The weighing assembly 15 is used to weigh the powder and slag falling into the tank body 12. The weighed powder and slag fall below the weighing assembly 15 and are located inside the tank body 12. A frame 16 is provided on the outer periphery of the tank body 12. The frame 16 is used to fix the tank body 12 and keep the tank body 12 in a vertical position. The weighing assembly 15 can be selected from existing technology and installed inside the tank body 12 to realize one or more weighings of the powder and slag falling into the tank body 12. The weighing information of one or more weighings can be displayed on the display screen 14 for observation.

[0049] Preferably, the weighing assembly 15 includes a weighing sensor, a weighing hopper, and a controller. The controller controls the automatic unloading of the weighing hopper. The weighing hopper is located inside the tank 12 and vertically in the middle position, capable of receiving the powder and slag falling into the tank 12. The weighing sensor weighs the hopper and transmits the weight signal to the display screen 14. The controller and display screen 14 are mounted on the outer wall of the tank 12 and can display the weighing information. After weighing, the automatic unloading of the weighing hopper can be achieved by operating the controller, allowing the powder and slag to fall to the bottom of the tank 12, thus realizing one weighing of the powder and slag. If weighing is required again, the previous operation can be repeated. The display screen 14 can record the information of each weighing.

[0050] In some embodiments, please refer to 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 the same as the corresponding information of the valve. 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. When the information from the identification terminal 4 is different from the valve information, the alarm module issues an alarm signal. The aforementioned receiving module, judgment module, control module, display module, and alarm module can all adopt existing technology products, and can realize functions such as receiving information, judging and analyzing information, controlling the opening and closing of valves, displaying information, and alarming after errors in analysis.
