Description

Technical Field

[0001] This utility model belongs to the field of powder material processing technology, and in particular relates to a vibrating screen device for removing impurities from aluminum powder. Background Technology

[0002] With the development of the aluminum industry and the increasing demand for resource recycling, aluminum powder is being used more and more widely in metallurgy, additive manufacturing, chemical industry, and aerospace. In the production and recycling of aluminum powder, to ensure its purity, screening processes are often used to remove impurity particles.

[0003] Currently, most vibrating screening devices use a structure where the vibrating motor directly drives the screen. However, in actual screening processes, vibrating screening devices are mostly open designs, with the screen exposed to the external environment. During high-frequency vibrating screening, aluminum powder is easily dispersed into the surrounding space, causing material waste and environmental pollution. In addition, the screen is easily clogged by fine aluminum powder. Once clogging occurs, the machine must be stopped for cleaning, which seriously affects the continuity of production and overall efficiency.

[0004] Therefore, it is necessary to design a vibrating screen device for removing impurities from aluminum powder in order to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing vibrating screening devices, which are open structures that easily lead to aluminum powder leakage and waste, environmental pollution, and easy clogging of the screen by fine aluminum powder, requiring frequent shutdowns for cleaning and affecting production continuity and overall efficiency, this utility model provides a vibrating screen device for removing impurities from aluminum powder.

[0006] This utility model is achieved through the following technical means: A vibrating screen device for removing impurities from aluminum powder includes a frame, a guide shell, a frame body, a screen, a support plate, a motor, a turntable, a column, a guide frame, and a striking assembly. The guide shell is installed on the frame, and a discharge port is opened at the lower front part of the guide shell. The frame body is slidably installed on the upper part of the guide shell, with a feed inlet at the higher front part and a discharge port at the lower rear part. The screen is installed obliquely inside the frame body, and the screen body is in a front-high, rear-low orientation, with the highest point of the screen body close to the feed inlet and the lowest point close to the discharge port. The discharge port is located at... Below the screen, the inside of the guide shell has an inclined surface. The inclined surface is located below the screen and has an overall shape that is lower in the front and higher in the back. The lowest point of the inclined surface is close to the discharge port. The support plate is installed at the front of the guide shell, the motor is installed at the bottom of the support plate, and the turntable is rotated at the top of the support plate. The output shaft of the motor passes through the support plate and the turntable and is fixedly connected to the turntable. The column is fixed at the edge of the turntable. The guide frame is installed at the front of the frame. The column extends into the reserved slide groove at the rear of the guide frame and slides with the guide frame through the slide groove. The hammering component is set between the guide shell and the frame.

[0007] Furthermore, it is particularly preferred that the striking assembly includes a connecting rod, a rack, a support base, a bearing, a rotating shaft, flexible levers, and gears. Two connecting rods arranged side by side are installed at the rear of the frame, and a rack is fixed to one end of each connecting rod. Two support bases arranged side by side are installed at the rear of the guide shell. A bearing is rotatably installed inside each support base, and a rotating shaft is rotatably installed between the two bearings. Multiple flexible levers are fixed to the outside of the rotating shaft in a horizontal direction at equal intervals. Gears are fixed to both ends of the rotating shaft. The number of gears is the same as the number of racks, and the racks are located above and mesh with the corresponding gears.

[0008] In addition, it is particularly preferred that the device also includes rollers, with limiting grooves provided on both sides of the flow guide shell, and two rollers arranged in parallel on both sides of the frame. The two longitudinally aligned rollers are located in the corresponding limiting grooves and form a sliding fit with the limiting grooves.

[0009] In addition, it is particularly preferred that the device also includes a placement rack, a collection frame one, and a collection frame two. The placement rack is installed at the rear of the frame, the collection frame one is placed on the placement rack, the rear of the discharge port is located above the collection frame one, and the collection frame two is slidably placed at the front of the frame, with the discharge port located above the collection frame two.

[0010] Furthermore, it is particularly preferred that the gear and the rack have the same thickness.

[0011] Furthermore, it is particularly preferred that both collection box one and collection box two are provided with two symmetrically distributed handles.

[0012] Beneficial effects: 1. By constructing a semi-enclosed screening environment through the guide shell and frame, the aluminum powder can be effectively reduced during the screening process, thus reducing material waste and pollution to the working environment. At the same time, the striking component can intermittently strike the guide shell, so that the vibration of the guide shell is transmitted to the frame, which in turn makes the screen vibrate, which helps to shake off the fine aluminum powder attached to the screen, effectively avoiding screen clogging and improving screening efficiency and screening quality.

[0013] 2. By setting up the placement rack, collection frame one, and collection frame two, impurities and aluminum powder are collected in a sealed manner, effectively preventing aluminum powder from escaping during the collection process, and further reducing material loss and environmental pollution.

[0024] Example: A vibrating screen device for removing impurities from aluminum powder, such as... Figures 1-8As shown, the assembly includes a frame 1, a guide shell 2, a frame 3, a screen 4, a support plate 6, a motor 7, a turntable 71, a column 8, a guide frame 9, and a striking assembly. The guide shell 2 is bolted to the frame 1. A discharge port 22 is located at the lower front of the guide shell 2. The frame 3 is slidably mounted on the upper part of the guide shell 2. A feed inlet 31 is located at the higher front of the frame 3, and a discharge outlet 32 ​​is located at the lower rear. The screen 4 is bolted inside the frame 3, and the screen 4 has a front-high, rear-low profile. The highest point of the screen 4 is close to the feed inlet 31, and the lowest point is close to the discharge outlet 32. The discharge outlet 22 is located below the screen 4. The guide shell 2 has an inclined surface inside, located below the screen 4, and also has a front-low, rear-high profile. The lowest point of the inclined surface is close to the screen 4. The discharge port 22 and the support plate 6 are fixed to the front of the guide shell 2 by bolts. The motor 7 is fixed to the bottom of the support plate 6 by bolts. The output shaft of the motor 7 extends vertically upward and is a geared motor that can provide a stable and appropriate speed. The turntable 71 is rotatably set on the upper part of the support plate 6. The output shaft of the motor 7 passes through the support plate 6 and the turntable 71 and is fixedly connected to the turntable 71. The column 8 is fixedly connected to the edge of the turntable 71. The guide frame 9 is fixed to the front of the frame 3 by bolts. The column 8 extends into the reserved slide groove at the rear of the guide frame 9 and slides with the guide frame 9 through the slide groove, thereby converting the rotational motion of the turntable 71 into the reciprocating linear motion of the guide frame 9. The striking component is set between the guide shell 2 and the frame 3.

[0025] like Figure 1 , Figure 6 and Figure 7 As shown, the striking assembly includes a connecting rod 10, a rack 11, a support base 12, a bearing 13, a rotating shaft 14, flexible levers 15, and gears 16. Two connecting rods 10 arranged side-by-side are bolted to the rear of the frame 3. A rack 11 is fixedly connected to the lower end of each connecting rod 10. Two support bases 12 arranged side-by-side are bolted to the rear of the guide shell 2. A bearing 13 is rotatably mounted inside each support base 12. A rotating shaft 14 is rotatably mounted between the two bearings 13. Multiple flexible levers 15, evenly spaced horizontally, are fixedly connected to the outside of the rotating shaft 14. Gears 16 are fixedly connected to both ends of the rotating shaft 14. The number of gears 16 is the same as the number of racks 11. The racks 11 are positioned above and mesh with the corresponding gears 16. Power transmission and conversion are achieved through the cooperation of the gears 16 and racks 11. The gears 16 and racks 11 have the same thickness, ensuring uniform force distribution during meshing, reducing wear, and improving transmission stability and reliability.

[0026] like Figure 1 , Figure 4 and Figure 6As shown, it also includes rollers 5. Limiting grooves 21 are opened on both the left and right sides of the flow guide shell 2. Two rollers 5 are rotatably arranged on both the left and right sides of the frame 3. The two longitudinally aligned rollers 5 are located in the corresponding limiting grooves 21 and form a sliding fit with the limiting grooves 21. Through the cooperation between the rollers 5 and the limiting grooves 21, the movement of the frame 3 can be guided, reducing the sliding friction between the frame 3 and the flow guide shell 2.

[0027] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a placement rack 17, a collection frame 18, and a collection frame 19. The placement rack 17 is installed at the rear of the frame 1. The collection frame 18 is placed on the placement rack 17. The rear of the discharge port 32 is located above the collection frame 18. The collection frame 19 is slidably placed at the front of the frame 1. The discharge port 22 is located above the collection frame 19. Both the collection frame 18 and the collection frame 19 are provided with two symmetrically distributed handles to facilitate the operator to move and pick up the collection frame 18 and the collection frame 19.

[0028] In use, the operator first starts the motor 7. The output shaft of the motor 7 drives the turntable 71 to rotate, and the turntable 71 drives the column 8 to rotate together. When the column 8 rotates, it slides continuously along the slide groove of the guide frame 9, thereby driving the guide frame 9 to move continuously backward and forward. The frame 3 moves back and forth with the guide frame 9. At this time, the aluminum powder to be screened is poured into the frame 3 from the feed port 31. After the aluminum powder enters the frame 3, it flows onto the screen 4. The screen 4 moves with the frame 3 to screen the aluminum powder. During the screening process, the aluminum powder falls through the screen 4 into the inside of the guide shell 2 and slides down the inclined surface of the guide shell 2 to the discharge port 22. It is then concentrated and discharged into the collection frame 19 from the discharge port 22. The impurities in the aluminum powder are intercepted on the screen 4 and slide backward along the inclined angle of the screen 4 to the discharge port 32. During the backward movement of the frame 3, the area of ​​the discharge port 32 aligned with the collection frame 18 becomes larger, which is conducive to quickly discharging the impurities into the collection frame 18.

[0029] As the frame 3 moves backward and forward, it drives the connecting rod 10 to move back and forth. The connecting rod 10 then drives the rack 11 to move back and forth. When the rack 11 moves backward, it meshes with the gear 16 in the forward direction, which in turn drives the gear 16 to drive the rotating shaft 14 to rotate counterclockwise. This causes the flexible lever 15 to strike the outer wall of the guide shell 2. The guide shell 2 vibrates after being struck, and this vibration is transmitted to the frame 3, causing the screen 4 to vibrate as well. This helps to shake off the fine aluminum powder attached to the screen 4. When the rack 11 moves forward, it meshes with the gear 16 in the reverse direction, which in turn drives the gear 16 to drive the rotating shaft 14 to rotate clockwise to reset. This causes the flexible lever 15 to return to its initial position. This cycle repeats, with the flexible lever 15 intermittently striking the outer wall of the guide shell 2, causing the screen 4 to vibrate intermittently, improving the screening effect and preventing the screen 4 from clogging.

[0030] After screening, turn off motor 7, remove collection frame 18 and collection frame 2 19, and pour out the collected impurities and aluminum powder.
