Description

Technical Field

[0001] This utility model relates to the field of centrifuge separation, specifically a spiral scraper installed in a horizontal centrifuge. Background Technology

[0002] In coal slime solid-liquid separation processes, horizontal centrifuges are commonly used equipment. However, the scrapers in traditional horizontal centrifuges are significantly inadequate in pushing materials. Traditional scrapers employ a relatively simple method of material pushing, lacking a systematic design. During centrifuge operation, they struggle to flexibly and effectively push materials according to the characteristics of the material and the centrifuge's operating state. Due to the limitations of the pushing method, uniform material distribution within the centrifuge cannot be guaranteed, often resulting in localized material accumulation.

[0003] Material buildup inside a centrifuge can cause several problems. On the one hand, it leads to incomplete solid-liquid separation, resulting in solids containing a significant amount of water and liquids with high impurity content, which affects production quality. On the other hand, material buildup can hinder the normal operation of the centrifuge, increasing operating resistance, energy consumption, and wear and tear, shortening its lifespan and increasing maintenance and replacement costs. Furthermore, to address the material buildup problem, operators often need to frequently intervene manually, such as adjusting the material distribution, which not only increases labor costs but also reduces production efficiency. Therefore, there is an urgent need to develop a new type of scraper that can effectively solve these problems. Utility Model Content

[0017] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0018] Please see Figures 1 to 3This utility model provides a technical solution: a spiral scraper installed in a horizontal centrifuge, including a scraper structure 1. The scraper structure 1 is installed at the front end of the external horizontal centrifuge. The scraper structure 1 includes a scraper body 15 and a centrifuge inner liner 16. The scraper body 15 is located inside the centrifuge inner liner 16. The scraper body 15 includes a cylindrical blade 151. One end of the cylindrical blade 151 is fixedly connected to a rotating seat 152. The outer wall of the cylindrical blade 151 is fixedly connected to a threaded protrusion 153. The threaded protrusion 153 is provided in several groups and is evenly distributed on the outer wall of the cylindrical blade 151.

[0019] Furthermore, one end of the cylindrical blade 151 has an opening, and the rotating shaft 13 passes through the opening and is rotatably connected to the rotating seat 152 and the cylindrical blade 151.

[0020] The scraper body 15 has a rotating shaft 13 fixedly connected inside, and a limit wheel 14 is rotatably connected in the middle section of the rotating shaft 13.

[0021] The scraper structure 1 also includes a drive motor 11, and a belt 12 is fitted between the output shaft of the drive motor 11 and the rotating shaft 13.

[0022] The centrifuge inner liner 16 is fixedly connected to the inside of the external horizontal centrifuge. The external horizontal centrifuge has a motor bracket installed at the drive motor 11, and the drive motor 11 is fixedly connected inside the motor bracket. The external horizontal centrifuge has a protective shell installed at the belt 12. The belt 12, the rotating shaft 13, and the limit wheel 14 are all installed inside the protective shell.

[0023] During use, the drive motor 11 drives the rotating shaft 13 to rotate via the belt 12. The rotating shaft 13 drives the scraper body 15 to rotate. When the scraper body 15 rotates, several sets of threaded protrusions 153 on its surface are attached to the inner wall of the centrifuge liner 16 and rotate. During the rotation, the scraper body 15 comes into contact with the material, and the threaded protrusions 153 continuously and evenly disperse the material in all directions, effectively preventing the material from accumulating in a local area. During the rotation, the threaded protrusions 153 can continuously apply force to the material, so that the material is continuously agitated and dispersed.

[0024] The limiting wheel 14 is fixed inside the external centrifuge and can limit the rotation shaft 13 to prevent the rotation shaft 13 from shifting back and forth during rotation, thereby affecting the rotation of the scraper body 15.

[0025] Compared to traditional scrapers, the scraper body 15 of this device, with its unique spiral blade structure design, can continuously and evenly apply a pushing force to the material like a screw during centrifuge operation. This continuous and uniform pushing force ensures that the material maintains a good distribution state within the centrifuge, thereby improving the solid-liquid separation effect, ensuring production quality, and reducing equipment operating resistance, energy consumption, and service life by avoiding local material accumulation. This also reduces equipment maintenance and replacement costs. Furthermore, the spiral scraper of this device can automatically achieve uniform material distribution, reducing manual intervention by operators and saving labor costs.
