Technical Field

[0001] This utility model relates to the field of equipment for the harmless treatment of phosphogypsum, specifically a self-cleaning drive roller for a phosphogypsum conveyor belt. Background Technology

[0002] In the process of harmlessly treating phosphogypsum, the crushed phosphogypsum needs to be transported over a long distance using a belt conveyor before proceeding to the next processing step. To achieve environmental protection and dust suppression, water spraying is usually used during the crushing process. This results in relatively moist and sticky phosphogypsum powder after crushing. During belt conveyor transport, the phosphogypsum easily adheres to the conveyor belt, causing it to detach and spill onto and below the conveyor frame during the return trip, severely impacting the on-site environment. Furthermore, the accumulation of large amounts of phosphogypsum on the conveyor belt significantly reduces conveying efficiency and increases equipment energy consumption.

[0003] Although a self-cleaning roller for a belt conveyor is disclosed in CN 202864340 U, ​​this cleaning roller has a flat structure and cannot be well adapted to the V-shaped conveyor belt used for conveying phosphogypsum. Utility Model Content

[0004] To address the existing technical problems, the main objective of this utility model is to provide a self-cleaning drive roller for phosphogypsum conveyor belts. This roller can be used with phosphogypsum belt conveyors and employs a separate drive power unit. It can effectively clean the phosphogypsum adhering to the surface of the conveyor belt, prevent adhesion, and ensure efficient conveying of phosphogypsum. Moreover, it can adapt well to V-shaped conveyor belts.

Detailed Implementation

[0031] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0032] Example 1: Reference Figure 1-11The self-cleaning drive roller for the phosphogypsum conveyor belt includes a central shaft 6. A central support plate 2 is fixedly installed in the middle of the central shaft 6. Transmission sleeves 5 are symmetrically installed at both ends of the central shaft 6. Web plates 4 are fixed on the transmission sleeves 5. Conical cylinders 3 are fixed between the two outer sides of the central support plate 2 and the transmission sleeves 5. Scraper blades 1 with a V-shaped structure are evenly fixed on the outer edges of the central support plate 2 and the web plates 4 on both sides. The above-mentioned roller can be used with a phosphogypsum belt conveyor and adopts a separate drive power unit. It can effectively clean the phosphogypsum adhering to the surface of the conveyor belt, prevent adhesion, and ensure efficient conveying of phosphogypsum; moreover, it can be well adapted to V-shaped conveyor belts. In practical use, the entire central shaft 6 is supported above the V-shaped conveyor belt of the belt conveyor by rotating bearings, and the central shaft 6 is connected to the power unit. The power unit drives the central shaft 6, which in turn drives the entire self-cleaning drive roller to rotate. This causes the scraper 1 to come into contact with the outer surface of the V-shaped conveyor belt. During its rotation, the scraper 1 scrapes off the residual phosphogypsum adhering to the V-shaped conveyor belt, so that it can automatically fall off at the end of the conveyor, achieving the effect of self-cleaning of the conveyor belt.

[0033] Furthermore, the central shaft 6 includes a central shaft section 601, on which a first keyway 602 and a second keyway 603 are symmetrically machined. Both ends of the central shaft section 601 are bearing mounting shaft sections 604, and the ends of the bearing mounting shaft sections 604 are drive shaft sections 605. The outer surface of the end of the drive shaft section 605 is machined with a stepped platform 606, and multiple threaded blind holes 607 are machined at the end of the drive shaft section 605. The central shaft 6 can be used to support the entire self-cleaning drive drum and facilitates the rotation of the entire self-cleaning drive drum via a power unit. The first keyway 602 and the second keyway 603 facilitate the subsequent installation of a flat key, thereby driving the mating drive sleeve 5 to transmit torque and rotate the drive sleeve 5, which in turn drives the web plate 4 to rotate. The bearing mounting shaft section 604 facilitates the subsequent installation of bearings, thereby rotatably supporting the entire central shaft 6 on the drum frame.

[0034] Furthermore, the central support plate 2 includes a central sleeve 201 fitted onto the central shaft 6. The central sleeve 201 is fitted onto the central shaft section 601, and a circular plate 202 is provided on the outside of the central sleeve 201. The central support plate 2 facilitates the support of the conical cylinder 3, and the conical cylinder 3 and the circular plate 202 form a closed space, thereby protecting the central shaft 6. At the same time, the conical cylinder 3 facilitates the removal of phosphogypsum that may occasionally fall onto its outer surface.

[0035] Furthermore, the transmission sleeve 5 includes a sleeve body 501, with a shaft hole 505 machined at its center. A third keyway 504 is machined on the inner wall of the shaft hole 505. The third keyway 504 engages with a first keyway 602 or a second keyway 603 on the central shaft 6 via a flat key. A shoulder 502 is provided on the sleeve body 501, and multiple screw holes 506 are evenly machined around the circumference of the shoulder 502. A chamfer 503 is machined at the end of the sleeve body 501, which is used to connect with the tapered cylinder 3. The transmission sleeve 5 described above can be used to transmit the rotational power of the central shaft 6, and at the same time facilitates the fixed installation of the web plate 4. During operation, torque is transmitted through the central shaft 6 and the flat key, thereby synchronously driving the transmission sleeve 5 to rotate.

[0036] Furthermore, the web plate 4 includes a web plate body 401, with a web plate circular hole 403 machined at its center. The web plate circular hole 403 is used to mate with the sleeve body 501. The web plate body 401 has multiple sets of evenly arranged web plate holes 402 machined on it. The web plate 4 facilitates reliable support and fixation of the scraper blade 1, thereby ensuring that the scraper blade 1 can form a roller shape to adapt to the V-shaped conveyor belt.

[0037] Furthermore, the outer diameter of the web plate 4 is smaller than the outer diameter of the central support plate 2. This dimensional fit ensures the stable and reliable installation of the scraper blade 1, thus adapting well to the V-shaped conveyor belt used for phosphogypsum transport and improving the cleaning effect on the conveyor belt.

[0038] Example 2: Furthermore, during installation, the central shaft 6 is mounted on the frame of the belt conveyor via bearings and a bracket, and the scraper blade 1 is in contact with the outer surface of the conveyor belt. This installation structure allows the entire self-cleaning drive roller to be mounted on the belt conveyor during subsequent use, enabling the scraper blade 1 to loosen the phosphogypsum adhering to the outer surface of the conveyor belt. This ensures that the phosphogypsum automatically detaches from the end of the conveyor belt without leaving any residue, thus achieving the purpose of cleaning the conveyor belt.

[0039] Example 3: Furthermore, during installation, the drive shaft section 605 of the central shaft 6 engages with the output shaft of the motor to transmit torque. By using the aforementioned motor as the power device to drive the central shaft 6, the automatic rotation of the entire self-cleaning drive roller is ensured during operation, thereby achieving the final cleaning effect.

[0040] The working process and principle of this utility model: In the specific working process, the entire self-cleaning drive roller is installed on the belt conveyor, and the scraper blade 1 is made to fit against the outer surface of the conveyor belt. Then, the motor is started, and the motor drives the central shaft 6. The central shaft 6 will synchronously drive the transmission sleeve 5. The transmission sleeve 5 transmits the rotational power of the central shaft 6, and at the same time drives the web plate 4. The web plate 4 synchronously drives the scraper blade 1. The scraper blade 1 scrapes off the residual phosphogypsum adhering to the V-shaped conveyor belt, so that it can automatically fall off at the end of the conveyor, thus achieving the self-cleaning effect of the conveyor belt.
