Description

Technical Field

[0001] This utility model relates to the field of powder sieving technology, and in particular to a high-efficiency powder sieving device. Background Technology

[0002] When screening powder and granular products, vibration is used to accelerate the separation efficiency of powder on the screen.

[0003] In Chinese utility model patents, such as CN219233048U, a high-efficiency powder sieving and separation device is disclosed. By using the vibration of a vibrator in conjunction with the continuous scraping of the sieving powder by a scraper, the powder sieving efficiency can be effectively accelerated while preventing the sieving powder from clogging the screen, thus improving the efficiency of powder sieving. At the same time, the screen can be easily removed for cleaning to ensure the sieving efficiency of the screen. This effectively solves the problems of low sieving efficiency and easy clogging and difficult cleaning of traditional powder sieving devices.

[0004] The above-mentioned technology improves the screening efficiency of the screen by using a scraper, thereby achieving efficient screening of powder. However, the screened powder accumulates on the top of the screen during the screening process. When the screen accumulates too much and affects the screening efficiency, the screen needs to be manually disassembled for cleaning, which in turn affects the efficiency of the entire production process. Therefore, it is necessary to propose an efficient powder screening device to address the above problems. Utility Model Content

[0016] 1. This utility model is equipped with a rotating mechanism, a filter plate, a connecting rod mechanism, a connecting channel, and a waste channel.

[0024] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0025] This utility model provides a technical solution:

[0026] Reference Figure 1-5 A high-efficiency powder sieving device includes a sieving cylinder 1, with multiple vibrating devices 5 symmetrically installed on the outer side of the sieving cylinder 1. An elastic support 2 is fixedly installed on the bottom surface of the sieving cylinder 1. A feed pipe 3 and a discharge pipe 4 are fixedly connected to the top and bottom of the sieving cylinder 1, respectively. A filter plate 11 is rotatably connected inside the sieving cylinder 1. A rotating mechanism is provided on the outer side of the sieving cylinder 1, and the rotating mechanism drives the filter plate 11 to rotate. An elastic sealing ring 12 is installed on the outer side of the filter plate 11, and the elastic sealing ring 12 abuts against the side wall of the sieving cylinder 1. A waste channel 6 is fixedly connected to the outer side of the sieving cylinder 1. A connecting channel 20 is rotatably connected to the inner wall of the waste channel 6. A rotating plate 19 is rotatably connected inside the filter plate 11. A connecting rod mechanism is provided on the bottom surface of the filter plate 11, and both the connecting channel 20 and the rotating plate 19 are connected to the connecting rod mechanism. A rotating rod 13 is rotatably connected to the top wall of the sieving cylinder 1, and a scraper 16 is rotatably connected to the bottom end of the rotating rod 13. A dust collection mechanism is provided on the outer side of the sieving cylinder 1.

[0027] It should be noted that the vibration device 5 and the elastic support 2 are technologies mentioned in the comparative documents. They mainly provide vibration for the screening cylinder 1 to improve screening efficiency. The filter plate 11 can be rotated through the rotation mechanism and is connected to the rotating plate 19 through the linkage mechanism. When the filter plate 11 rotates, the rotating plate 19 and the connecting channel 20 can be pulled to rotate through the linkage mechanism. When the connecting channel 20 does not rotate, the waste channel 6 can be blocked. Then, the rotating plate 19 rotates to the top of the connecting channel 20. With the tilt of the filter plate 11, the powder accumulated on the top of the filter plate 11 can slide into the connecting channel 20 and enter the waste channel 6 under the action of gravity, realizing automatic cleaning without disassembling the filter plate 11, improving production efficiency and making continuous powder screening more efficient.

[0028] Furthermore, the linkage mechanism includes multiple first support rods 21, which are symmetrically fixedly installed on the bottom surface of the filter plate 11. The other end of each first support rod 21 is movably connected to the outside of the connecting channel 20. A second support rod 22 is fixedly installed on the outside of each first support rod 21, and each second support rod 22 is rotatably connected to the bottom surface of the rotating plate 19. It should be noted that the movable connection between the first support rod 21 and the connecting channel 20 allows the first support rod 21 to pull the connecting channel 20 to rotate within the waste channel 6. The second support rod 22, along with the rotation of the first support rod 21, causes the rotating plate 19 to rotate.

[0029] Furthermore, the rotating mechanism includes two mounting brackets 17, which are symmetrically mounted on the outside of the screening cylinder 1. Each mounting bracket 17 is rotatably connected to a rotating shaft 14, and the other end of each rotating shaft 14 is fixedly connected to the outside of the filter plate 11. A motor 18 is fixedly mounted on the outside of one of the mounting brackets 17, and the output shaft of the motor 18 is connected to the rotating shaft 14 at the corresponding position. The motor 18 is a stepper motor, which can precisely control the rotation angle of the filter plate 11 and limit the filter plate 11 to that angle.

[0030] Furthermore, the dust collection mechanism includes a vacuum cleaner 7, and the suction end of the vacuum cleaner 7 is connected to the inside of the sieving cylinder 1. A connecting seat 8 is fixedly installed on the outside of the sieving cylinder 1, and the dust discharge end of the vacuum cleaner 7 is connected to the connecting seat 8. A dust collection bag 9 is fixedly connected to the outside of the connecting seat 8. The vacuum cleaner 7 sucks up the dust generated when the powder vibrates and collects it through the dust collection bag 9, which facilitates the subsequent recycling of this part of the powder and reduces the waste of resources.

[0031] Furthermore, two spring telescopic rods 15 are symmetrically installed on the bottom surface of the rotating rod 13, and the bottom end of each spring telescopic rod 15 is rotatably connected to the top surface of the scraper 16. The spring telescopic rods 15 can make the scraper 16 always stick tightly to the top surface of the filter plate 11.

[0032] Furthermore, a drive device 10 is installed on the top surface of the screening cylinder 1, and the bottom end of the drive device 10 is connected to the rotating rod 13. The specific implementation of the drive device 10 has been described in detail in the prior art and will not be repeated here. Valves are installed on both the feed pipe 3 and the discharge pipe 4.

[0033] In practical use, the working principle of this utility model is as follows:

[0034] In this invention, the device is used as follows: powder is conveyed into the sieve cylinder 1 through the feed pipe 3. At this time, the filter plate 11 is in a horizontal state, and the powder is supported by the filter plate 11. Multiple vibration devices 5 on the outside of the sieve cylinder 1 are activated to vibrate the sieve cylinder 1 and assist the elastic support 2 and the drive device 10 in driving the rotation of the rotating rod 13 to scrape the surface of the filter plate 11. This allows the filter plate 11 to filter the powder efficiently. At the same time, the dust in the sieve cylinder 1 can be extracted by activating the vacuum cleaner 7 and discharged into the dust collection bag 9. The dust is collected by the dust collection bag 9, which facilitates the recycling of the powder in the dust.

[0035] When a large amount of waste material accumulates on the top surface of the filter plate 11, the valve on the feed pipe 3 is closed to stop the powder conveying. The motor 18 drives the rotating shaft 14 to rotate, causing the filter plate 11 to rotate around the center of the rotating shaft 14. While the filter plate 11 is rotating, it drives the first support rod 21 to move synchronously, thereby pulling the connecting channel 20 to rotate and opening the waste channel 6. The second support rod 22 can pull the rotating plate 19 to rotate, positioning the rotating plate 19 above the connecting channel 20. At this time, the powder on the top surface of the filter plate 11 can enter the upper part of the connecting channel 20 through the inclined rotating plate 19 and be conveyed into the waste channel 6 through the inclined connecting channel 20, and then discharged from the screening cylinder 1. At the same time, when the filter plate 11 is discharging waste, the drive device 10 drives the rotating rod 13 to rotate. The multiple spring telescopic rods 15 make the scraper 16 closely adhere to the top surface of the filter plate 11, thereby driving the powder to flow out from the rotating plate 19 and accelerating the discharge efficiency.

[0036] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
