Abstract
Description
Technical Field
[0001] This utility model relates to the field of silver powder dust recovery technology, and in particular to a silver powder dust recovery device. Background Technology
[0002] Silver powder is widely used in electronics, inks, solar cells, and other fields. However, the fine dust generated during production and processing not only wastes resources but also pollutes the environment. Therefore, efficient recovery of silver powder dust for reuse has become a key technological challenge. Traditional methods such as filtration and electrostatic dust removal suffer from low efficiency or high cost. Modern technologies improve recovery rates through multi-stage dust removal, nanofiber filter materials, and closed recovery systems, while combining chemical purification or smelting processes to achieve silver powder recycling.
[0003] In existing technologies, silver powder dust recovery mainly relies on negative pressure dust collection systems. These systems draw silver shavings and powder generated during processing into a collection hopper through pipes. However, traditional collection hoppers typically employ fixed or simply movable structures, limiting their position and thus restricting the suction range. This is particularly problematic in large workshops or multi-station production environments, making efficient and comprehensive dust recovery difficult. This drawback not only reduces silver powder recovery efficiency but also increases the workload of manually adjusting the equipment.
[0004] In response to this technical problem, this application proposes a device for recovering silver powder dust. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a silver powder dust recovery device that allows the collection hopper to be adjusted in multiple directions, significantly improving the flexibility and range of dust collection, realizing resource recycling, and enhancing filter cleaning efficiency and the convenience of silver powder recovery.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A silver powder dust recovery device includes a collection chamber, a connecting frame fixedly connected to the top of the collection chamber, a second motor fixedly connected to the front end of the connecting frame, a first motor fixedly connected to the right end of the connecting frame, a locking column connected to the drive end of the first motor via an adjustment assembly, a collection hopper fixedly connected to the bottom end of the locking column, a fixed platform rotatably connected to the top left end of the connecting frame, an opening and closing door rotatably connected to the front end of the collection chamber, a fixed plate fixedly connected to the inner wall of the collection chamber, and a third motor fixedly connected to the bottom end of the collection chamber. A cleaning wheel is connected to the drive end of the third motor via a cleaning assembly.
[0008] Furthermore, the adjustment assembly includes a screw two fixedly connected to the drive end of the motor two, and a movable frame two is threadedly connected to the outer wall of the screw two, and the outer wall of the movable frame two is slidably connected to the inner wall of the connecting frame.
[0009] Furthermore, a screw is fixedly connected to the drive end of the motor, and a movable frame is threadedly connected to the outer wall of the screw. The outer wall of the movable frame is slidably connected to the connecting frame.
[0010] Furthermore, a sliding rod is fixedly connected to the outer wall of the fixed platform, and a transition column is slidably connected to the outer wall of the sliding rod. The bottom end of the transition column is rotatably connected to the top end of the fitting column.
[0011] Furthermore, a connecting pipe is fixedly connected to the outer wall of the collection hopper, and the other end of the connecting pipe is fixedly connected to the left end of the collection chamber and passes through it.
[0012] Furthermore, a fixed frame is fixedly connected to the right end of the collection chamber, and several negative pressure fans are installed on the inner wall of the fixed frame.
[0013] Furthermore, the cleaning assembly includes a transmission frame fixedly connected to the three drive ends of the motor, a filter screen fixedly connected to the bottom end of the inner wall of the fixed plate, and the outer wall of the transmission frame rotatably connected to the inner wall of the filter screen.
[0014] Furthermore, a toothed ring is fixedly connected to the inner wall of the fixing plate, and a transmission gear is fixedly connected to the opposite end of each cleaning wheel. The toothed ring and the transmission gear are meshed together.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, when the external control is started, the negative pressure fan forms a negative pressure chamber in the collection bin, and the silver powder is adsorbed to the filter screen through the connecting pipe. The second motor drives the second screw to drive the second moving frame, so that the collection bin moves along the Y-axis; the first motor drives the first screw to drive the first moving frame, so as to realize the movement of the X-axis. This dual-axis linkage design allows the collection bin to be adjusted in multiple directions, which significantly improves the vacuuming flexibility and collection range.
[0017] 2. In this utility model, the motor three-drive transmission frame drives the cleaning wheel to roll along the filter screen, while the toothed ring causes the cleaning wheel to rotate through the transmission gear. The dual motion effectively scrapes off the silver powder on the surface of the filter screen, prevents clogging, and ensures continuous and efficient adsorption in the collection hopper. After the operation is completed, the negative pressure fan is turned off, and the opening and closing door can be opened to recover the silver powder in the collection chamber, realizing resource recycling. This design significantly improves the filter screen cleaning efficiency and the convenience of silver powder recovery. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1-3 This utility model provides an embodiment of a silver powder dust recovery device, comprising a collection bin 1, a connecting frame 2 fixedly connected to the top of the collection bin 1, a second motor 5 fixedly connected to the front end of the connecting frame 2, a first motor 4 fixedly connected to the right end of the connecting frame 2, a locking post 19 connected to the drive end of the first motor 4 via an adjustment assembly, a collection hopper 20 fixedly connected to the bottom end of the locking post 19, and an adjustment assembly including a second screw 14 fixedly connected to the drive end of the second motor 5, a second movable frame 16 threadedly connected to the outer wall of the second screw 14, and a second movable frame 16. The outer wall of the movable frame 16 is slidably connected to the inner wall of the connecting frame 2. The drive end of the motor 4 is fixedly connected to the screw 13. The outer wall of the screw 13 is threadedly connected to the movable frame 15. The outer wall of the movable frame 15 is slidably connected to the connecting frame 2. The outer wall of the fixed platform 6 is fixedly connected to the slide rod 7. The outer wall of the slide rod 7 is slidably connected to the adapter column 11. The bottom end of the adapter column 11 is rotatably connected to the top end of the fitting column 19. The outer wall of the collection hopper 20 is fixedly connected to the connecting pipe 21. The other end of the connecting pipe 21 is fixedly connected to the left end of the collection chamber 1 and passes through it.
[0027] Specifically, in the silver powder dust recovery device, when the electronic equipment is activated via an external control system, the negative pressure fan 10 first forms a negative pressure chamber within the collection chamber 1. The collection hopper 20 is connected to the surface of the collection chamber 1 via the connecting pipe 21. The scattered silver powder dust is directionally recovered using the principle of negative pressure adsorption, and the dust-laden airflow is ultimately guided to the filter screen 18 to complete gas-solid separation. To achieve multi-stage movement and expansion of the collection hopper 20, motor 25 drives screw 24 to rotate, causing the moving frame 26 to move along the Y-axis. The engaging column 19 pulls the collection hopper 20 to move synchronously. Simultaneously, motor 4 drives screw 13 to rotate, causing the moving frame 15 to translate along the X-axis, further driving the collection hopper 20 to perform horizontal bidirectional adjustment. This dual-axis linkage structure enables the collection hopper 20 to achieve precise positioning and multi-directional coverage within the X / Y-axis plane, significantly improving dust collection flexibility and operating range, and effectively solving the problems of low dust recovery efficiency and numerous blind spots caused by the limited movement of traditional fixed collection hoppers.
[0028] Reference Figure 4 and Figure 5 A fixed platform 6 is rotatably connected to the top left end of the connecting frame 2. An opening and closing door 8 is rotatably connected to the front end of the collection chamber 1. A fixed plate 12 is fixedly connected to the inner wall of the collection chamber 1. A motor 3 22 is fixedly connected to the bottom end of the collection chamber 1. A cleaning wheel 3 is connected to the drive end of the motor 3 22 through the cleaning assembly. A fixed frame 9 is fixedly connected to the right end of the collection chamber 1. Several negative pressure fans 10 are installed on the inner wall of the fixed frame 9. The cleaning assembly includes a transmission frame 17 fixedly connected to the drive end of the motor 3 22. A filter screen 18 is fixedly connected to the bottom end of the inner wall of the fixed plate 12. The outer wall of the transmission frame 17 is rotatably connected to the inner wall of the filter screen 18. A toothed ring 23 is fixedly connected to the inner wall of the fixed plate 12. A transmission gear 24 is fixedly connected to the opposite end of the cleaning wheel 3. The toothed ring 23 and the transmission gear 24 are meshed.
[0029] Specifically, during the operation of the silver powder dust recovery device, when motor 22 starts, it drives the transmission frame 17 to rotate around its axis, causing the cleaning wheel 3 mounted at its end to roll circumferentially along the outer surface of the filter screen 18. Simultaneously, the meshing transmission between the toothed ring 23 and the transmission gear 24 causes the cleaning wheel 3 to rotate, forming a "rolling + rotating" composite cleaning mode. This design allows the flexible scraper of the cleaning wheel 3 to continuously scrape the silver powder clumps adhering to the surface of the filter screen 18, effectively removing pore blockages and ensuring stable air permeability of the filter screen 18, thereby maintaining the high-efficiency filtration performance of the collection hopper 20 during the negative pressure adsorption process. After the silver powder recovery operation is completed, the negative pressure fan 10 stops operating, and the negative pressure environment inside the collection chamber 1 is released. At this time, the operator can directly access the silver powder deposited at the bottom of the collection chamber 1 by opening the opening door 8, and use the guide channel or powder collection box to complete the centralized recovery of the silver powder, realizing a clean and continuous resource reuse process. This device, through its synergistic design of automatic cleaning and manual recycling, extends the service life of the filter 18 and simplifies the silver powder recovery process, significantly improving the system's sustainable operation capability.
[0030] Working principle: When started by external control of various electronic devices, the negative pressure fan 10 forms a negative pressure chamber on the inner wall of the collection chamber 1, and the silver powder on the surface of the collection chamber 1 is recovered by the collection hopper 20 through the connecting pipe 21 and connected to the filter screen 18. The starter motor 25 drives the screw 24 to rotate, which causes the moving frame 26 to pull the engaging column 19 to move the collection hopper 20 along the Y-axis. The starter motor 4 drives the screw 13 to move the moving frame 15, which in turn moves the collection hopper 20 along the X-axis, allowing the collection hopper 20 to enter the collection chamber. The collection hopper 20 is adjustable in multiple directions to improve its suction flexibility and expand its collection range. When the motor 3 22 starts the transmission frame 17 to rotate, the cleaning wheel 3 at the transmission frame 17 rolls on the outside of the filter screen 18, and the toothed ring 23 drives the transmission gear 24 to make the cleaning wheel 3 rotate. The cleaning wheel 3 scrapes off the silver powder on the surface of the filter screen 18 to prevent the filter screen 18 from becoming clogged and to maintain the adsorption effect of the collection hopper 20. When the negative pressure fan 10 stops, the opening and closing door 8 can be opened to collect the silver powder in the collection chamber 1 for recycling.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
