Description

Technical Field

[0001] This utility model relates to the field of bentonite screening technology, specifically an alkaline pellet bentonite screening device. Background Technology

[0002] In current industrial production, the manufacturing process of basic pellets generally relies on the use of binders to ensure the strength and stability of the pellets. However, while binders perform well technically, their high price significantly impacts production costs. Extensive market research and in-depth technical analysis have revealed bentonite as a potential alternative. Not only is it inexpensive, but it is also widely available, offering significant economic advantages. To ensure the successful pelletizing of basic pellets, bentonite needs to be screened to prevent impurities from affecting subsequent smelting processes.

[0003] A novel bentonite fine screening device, disclosed in patent publication number CN219210569U, includes a rotating screening barrel, a base, a rotating ring, a material inlet, a transport trough, a bottom plate, an inner rotating barrel, an annular screen, and friction balls. The base is installed at the bottom of the rotating screening barrel, and the interior of the rotating screening barrel is connected to the interior of the base. A rotating ring is installed at the front end of the rotating screening barrel. An inner rotating barrel is installed inside the rotating screening barrel, and its sides are formed by an annular screen. A material inlet is located at the front end of the inner rotating barrel and is installed within the rotating ring at the front end of the rotating screening barrel. Several friction balls are installed inside the inner rotating barrel. A transport trough is located at the bottom of the base, and a bottom plate is installed at the bottom of the transport trough. This utility model has a reasonable design. By using the inner rotating barrel for screening, it reduces the dust generated during the screening process, and the friction balls inside the inner rotating barrel can crush large pieces of bentonite for further screening.

[0004] When the above-mentioned device screens bentonite, the friction ball crushes large pieces of bentonite while also crushing impurities in the bentonite. Therefore, the screened bentonite is easily mixed with impurities, resulting in poor screening efficiency. To address these issues, an alkaline pellet bentonite screening device is proposed.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[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] Please see Figures 1-5In this embodiment, an alkaline pellet bentonite screening device includes a housing 11, a screening cylinder 12 disposed inside the housing 11, and a screening box 13 disposed at the bottom of the screening cylinder 12. A drive rod 30 is rotatably connected to the screening cylinder 12, and the drive rod 30 is rotatably connected to the housing 11. Both ends of the drive rod 30 extending outside the housing 11 are fixedly connected to extension rods 21. An adjustment component for driving the screening box 13 to swing is provided on the extension rod 21.

[0027] The adjustment assembly includes arc-shaped blocks 15 and arc-shaped grooves 16. Two sets of arc-shaped blocks 15 are fixedly connected to both sides of the screening box 13, and two sets of arc-shaped grooves 16 are respectively opened on both sides of the box body 11. The arc-shaped blocks 15 are slidably connected in the arc-shaped grooves 16. A toothed plate is fixedly connected to the side of the arc-shaped block 15 away from the screening box 13. The toothed plate is meshed with a half gear 17. The half gear 17 is fixedly connected to a support rod. The support rod is rotatably connected to one side of the box body 11. A driven wheel 22 is fixedly connected to the support rod. The driven wheel 22 is connected to a driving wheel 23 via a synchronous belt. The driving wheel 23 is fixedly connected to an extension rod 21. A limiting member is provided on the box body 11 to guide the rotation of the arc-shaped blocks 15. A device for driving the extension rod 21 is installed on one side of the box body 11. A rotating motor 24 starts, driving an extension rod 21 to rotate. The extension rod 21 drives a drive wheel 23 to rotate, which in turn drives a driven wheel 22 to rotate via a synchronous belt. The driven wheel 22 drives a support rod to rotate, which in turn drives a half gear 17 to rotate. The half gear 17 meshes with a toothed plate, driving the toothed plate to move. The toothed plate drives an arc-shaped block 15 to move within an arc-shaped groove 16, which in turn drives a screening box 13 to rotate within a box body 11. When the half gear 17 rotates to a toothless position, the arc-shaped block 15 loses its meshing support and slides back along the arc-shaped groove 16 under gravity. When the half gear 17 meshes with the toothed plate again, the arc-shaped block 15 is re-driven to deflect, thereby driving the screening box 13 to swing back and forth to screen the bentonite, improving screening efficiency and reducing impurities.

[0028] The limiting component includes a fixed rod 18 and a limiting ring 19. Each of the two sets of fixed rods 18 has a set of arc-shaped blocks 15 fixedly connected to its bottom. The limiting ring 19 is fixedly connected to the top of the two sets of fixed rods 18. A limiting groove 20 is provided on one side of the housing 11 for sliding with the limiting ring 19. The limiting ring 19 is fitted onto the extension rod 21. The arc-shaped blocks 15 drive the fixed rods 18 to rotate, causing the limiting ring 19 to slide within the limiting groove 20, thus guiding and supporting the rotation of the arc-shaped blocks 15.

[0029] The drive rod 30 is equipped with a turning assembly, which includes two sets of scrapers 25. One side of each scraper 25 slides against the inner wall of the screening cylinder 12. The scrapers 25 are fixedly connected to the drive rod 30. A rubber plate is provided on the side of the scraper 25 that contacts the inner wall of the screening cylinder 12. When the drive rod 30 rotates, it also drives the scrapers 25 to rotate and screen the bentonite. The scrapers 25 can break up larger pieces of bentonite, making screening easier. At the same time, they turn the bentonite over, which facilitates screening. The rubber plate reduces damage to the inner wall of the screening cylinder 12.

[0030] The screening cylinder 12 is connected to a filter screen cover 26 by bolts on one side. By setting the filter screen cover 26, the screening cylinder 12 can be sealed to ensure screening airtightness, and at the same time it is easy to open and clean the large impurities remaining in the cylinder.

[0031] The screening box 13 is provided with filter plates 14 in the middle and bottom of its inner wall, and a rotating plate 29 is provided on one side of the screening box 13. The filter plates 14 facilitate the screening of bentonite, and the rotating plate 29 facilitates the cleaning of impurities in the screening box 13.

[0032] The top of the box 11 is provided with a box cover 27, and one side of the box 11 is provided with a box door 28. By providing the box cover 27, it is easy to disassemble and install the filter screen cover 26, and it is also easy to feed the bentonite. The box door 28 can clean the impurities in the screening box 13, and it is also easy to collect the screened bentonite.

[0033] The working principle of this utility model is as follows: In use, first lift the box cover 27 upwards, use a tool to open the filter screen cover 26, pour the bentonite to be screened into the screening cylinder 12, start the motor 24, drive the extension rod 21 to rotate, which in turn drives the drive rod 30 to rotate, simultaneously driving the scraper 25 to rotate and screen the bentonite. The scraper 25 can break up larger pieces of bentonite for easier screening, and also agitates the bentonite for easier sieving. The screened bentonite falls into the screening box 13, and the extension rod 21 simultaneously drives the drive wheel 23 to rotate. The drive wheel 23 drives the driven wheel 22 via a synchronous belt. The driven wheel 22 rotates, causing the support rod to rotate. The support rod then drives the half gear 17 to rotate. The half gear 17 meshes with the toothed plate, driving the toothed plate to move. The toothed plate drives the arc block 15 to move within the arc groove 16. The arc block 15 drives the screening box 13 to rotate within the box body 11. When the half gear 17 rotates to the toothless position, the arc block 15 loses its meshing support force and slides back along the arc groove 16 under the action of gravity. When the half gear 17 meshes with the toothed plate again, the arc block 15 is re-driven to deflect, thereby driving the screening box 13 to swing back and forth to screen the bentonite, improve the screening efficiency, and reduce impurity contamination.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
