Description

Technical Field

[0001] This utility model belongs to the field of pellet production, and in particular relates to a cleaning device for the feed plate of a disc pelletizer used in pellet production. Background technology: Pelletizing is an important method for agglomerating ore powder. It involves adding water and binders to form green pellets, which are then dried, preheated, and roasted to form ore pellets. It is particularly suitable for processing fine concentrate powders and is mainly used in blast furnace ironmaking and non-ferrous metal smelting.

[0002] The disc pelletizer is the main processing equipment for pellet production. Powdered material rolls and rubs within an inclined, rotating disc under the combined effects of gravity, centrifugal force, and friction, forming mother pellets after appropriate moisture is added. Once formed, the pellets automatically roll onto a chute located at the bottom edge of the disc, and are then conveyed by a belt conveyor to subsequent production lines. However, in actual production, because the formed pellets are not completely dry, some damp powder inevitably adheres to them as they roll within the disc. When the pellets fall onto the chute, this damp powder further adheres, eventually forming clumps. This obstructs normal pellet transport, significantly reducing transport efficiency. Furthermore, contact with clumps can cause pellets to splash and leak, exacerbating environmental contamination. Summary of the Invention

[0003] The purpose of this utility model is to provide a cleaning device for the feed plate of a disc pelletizer for pellet production, and to overcome the shortcomings of the prior art. It effectively solves the existing problem of powder sticking to the feed plate and affecting the normal conveying of pellets.

[0004] The present invention relates to a cleaning device for a disc pelletizing machine used in pellet production, comprising a chute plate, with guard plates vertically installed at both ends of the chute plate, a lead screw spanning across the chute plate, both ends of the lead screw being rotatably connected to the guard plates, one end of the lead screw being drive-connected to a drive motor mounted on the guard plates, a slider being drive-connected to the lead screw, a sliding elastic clamping assembly being provided below the slider, a scraper being provided on the sliding elastic clamping assembly, the bottom end of the scraper being slidably attached to the bottom wall of the chute plate, the sliding elastic clamping assembly including a support arm vertically installed on the bottom wall of the slider, a cylinder being installed at the bottom end of the support arm, a sliding rod being slidably connected in the inner cavity of the cylinder, a spring being fitted on the sliding rod, the spring being located between the inner end of the cylinder and the sliding rod, a lifting arm being connected to both the inner and outer ends of the sliding rod, and the scraper being provided below the lifting arm.

[0005] Furthermore, an annular top plate is coaxially fixedly fitted at the inner end of the cylinder and the inner end of the slide rod, and both ends of the spring are fixedly connected to the annular top plate.

[0006] Furthermore, the bottom end of the boom is fixedly connected to the concave mounting strip, and the scraper is installed in the groove of the concave mounting strip.

[0007] Furthermore, the scraper and the concave mounting strip are fixedly connected by bolts.

[0008] Furthermore, the bottom end of the scraper is pointed.

[0009] The beneficial effects of this utility model are as follows: The reciprocating movement of the slider driven by the lead screw allows the scraper to scrape laterally along the surface of the feed plate, thereby scraping off the powder adhering to the surface of the feed plate. This improves the efficient flow of the pellets on the feed plate, prevents pellets from splashing and overflowing, and reduces pollution of the production environment. At the same time, the sliding elastic clamping component ensures that the inner end of the moving scraper is always in contact with the edge of the disc pelletizer, so that the scraper can not only scrape off the powder adhering to the arc-shaped area at the top of the feed plate, but also scrape off the powder adhering to the edge of the disc pelletizer, further improving the cleaning effect of the adhering powder.

Detailed Implementation

[0011] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings: like Figures 1 to 3As shown, the cleaning device for the feed plate of a disc pelletizing machine for pellet production includes a feed plate 1. Guard plates 2 are vertically installed at both ends of the feed plate 1. A lead screw 3 spans across the feed plate 1, with both ends of the lead screw 3 rotatably connected to the guard plates 2. One end of the lead screw 3 is connected to a drive motor 4, which is mounted on the guard plates 2. A slider 5 is connected to the lead screw 3. A sliding elastic clamping assembly is located below the slider 5, and a scraper 6 is mounted on the sliding elastic clamping assembly. The bottom end of the scraper 6 slides against the bottom wall of the feed plate 1; the bottom end of the scraper 6 is pointed.

[0012] Specifically, the slider 5 is moved by the lead screw 3, so that the scraper 6 can scrape along the surface of the feed plate 1, thereby scraping off the powder adhering to the surface of the feed plate 1.

[0013] In actual use, a chute 1 is set at the bottom edge of the disc pelletizer. In order to better receive the pellets, the top of the chute 1 is opened into an arc shape that matches the bottom edge of the disc pelletizer. When the powder adheres to the surface of the chute 1, the drive motor 4 is started to drive the lead screw 3 to rotate, so that the slider 5 moves back and forth on the lead screw 3. At this time, the scraper 6 scrapes the adhered powder horizontally along the surface of the chute 1, avoiding the formation of clumps on the chute 1, thereby improving the efficient flow of the pellets on the chute 1, avoiding the phenomenon of pellets splashing and overflowing, and reducing the pollution of the production environment.

[0014] like Figures 1 to 3 As shown, the cleaning device for the feed chute of a disc pelletizing machine for pellet production includes a sliding elastic clamping assembly comprising a support arm 7 vertically mounted on the bottom wall of the slider 5, a cylinder 8 mounted at the bottom end of the support arm 7, a slide rod 9 slidably connected within the inner cavity of the cylinder 8, a spring 10 fitted on the slide rod 9, the spring 10 being located between the inner ends of the cylinder 8 and the slide rod 9, and a lifting arm 11 connected to both the inner and outer ends of the slide rod 9, with a scraper 6 positioned below the lifting arm 11; an annular top plate 12 coaxially fixedly fitted at the inner end of the cylinder 8 and the inner end of the slide rod 9, with both ends of the spring 10 fixedly connected to the annular top plate 12; the bottom end of the lifting arm 11 is fixedly connected to a concave mounting strip 13, and the scraper 6 is matchedly installed in the groove of the concave mounting strip 13; the scraper 6 and the concave mounting strip 13 are fixedly connected by bolts 14.

[0015] Specifically, by sliding the elastic clamping component, the inner end of the moving scraper 6 can always slide in contact with the edge of the disc pelletizer, so that the scraper 6 can not only scrape off the powder adhering to the arc-shaped area at the top of the chute 1, but also scrape off the powder adhering to the edge of the disc pelletizer, further improving the cleaning effect of the adhering powder.

[0016] In actual use, under the force of the spring 10, it can press tightly against the inner end of the slide rod 9, allowing the slide rod 9 to slide in the inner cavity of the cylinder 8, thereby driving the concave mounting strip 13 together with the scraper 6 to move towards the edge of the disc pelletizer, forcing the inner end of the scraper 6 to always slide in contact with the edge of the disc pelletizer. During the process of scraping the powder adhering to the center of the top wall of the chute 1 by the lateral movement of the scraper 6, the powder adhering to the arc-shaped area at the top of the chute 1 and the powder adhering to the edge of the disc pelletizer can also be scraped off together, further improving the cleaning effect of the adhering powder. In the above process, the annular top plate 12 can provide stable support for both ends of the spring 10, thereby preventing the spring 10 from slipping and deviating during the force process, and further improving the smoothness of the sliding rod 9 in the inner cavity of the cylinder 8; the scraper 6 and the concave mounting strip 13 are fixedly connected by bolts 14, so that the scraper 6 can be quickly disassembled and installed in subsequent maintenance or replacement processes.

[0017] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
