The spiral shaft does not occupy the space of the discharging end face, increasing the discharging area, improving the production efficiency, and being able to produce phosphogypsum lightweight aggregate particles with different particle sizes.

[0003] The above-mentioned existing phosphogypsum lightweight aggregate granulating device has the following deficiencies: The replaceable granulating die is arranged on the installation plate at the discharging port of the barrel body, which can meet the granulating requirements of different particle sizes of phosphogypsum. However, in actual production, the operator still needs to manually replace the granulating die, and the automation degree is low. Summary of the Utility Model

[0004] The utility model is to solve the above problems existing in the phosphogypsum lightweight aggregate granulating device of the prior art, and provides a phosphogypsum adjustable granulating device in which the granulating end faces with different granulating apertures are respectively aligned with the output end of the feeding barrel, and the granulating adjusting plate can automatically lift.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions: A phosphogypsum adjustable granulating device of the utility model includes a feeding barrel and a granulating adjusting plate. The granulating adjusting plate is erected in the vertical direction and has a plurality of granulating end faces with different granulating apertures. A sliding groove for the sliding assembly of the granulating adjusting plate is arranged at the output end of the feeding barrel. On both sides of the outer wall of the feeding barrel, there are respectively a driving mechanism for the lifting of the granulating adjusting plate and a guiding mechanism for the limiting of the granulating adjusting plate. On both sides of the back of the granulating adjusting plate, there are respectively racks and guide bars distributed along the length direction of the granulating adjusting plate. The driving mechanism includes a first fixing plate welded to one side of the outer wall of the feeding barrel and a servo motor assembled on the back of the first fixing plate. The output end of the servo motor penetrates through the first fixing plate and is fixedly installed with a gear meshing with the rack. A through hole for the meshing transmission of the rack and the gear is opened in the middle of one side of the sliding groove. The guiding mechanism includes a second fixing plate welded to the other side of the outer wall of the feeding barrel and a vertical frame welded to the front of the second fixing plate in the vertical direction. At the top and bottom of the front of the vertical frame, there are respectively fixedly installed limiting sliding seats slidingly adapted to the guide bars.

[0006] Preferably, it further includes an auxiliary support member embedded in the chute for positioning the granulation end face of the granulation adjusting plate. The auxiliary support member includes a lining plate, and a conical protrusion is provided on the front surface of the lining plate. A first conical structure is formed on the back of several granulation end faces on the granulation adjusting plate to form a receiving cavity for the conical protrusion to fit and embed. The lining plate is connected to the chute through four elastic components distributed in a rectangular array. Among them, the granulation adjusting plate is slidably assembled in the chute, and only the driving mechanism, the rack, the guiding mechanism and the guide bar provide structural support for the vertical erection of the granulation adjusting plate. Preferably, by providing an auxiliary support member, with the help of the mutually adapted conical protrusion and the receiving cavity formed by the first conical structure, under the action of the four elastic components, during the lifting process of the granulation adjusting plate, after the granulation end face is aligned with the output end of the material feeding cylinder, a pad support structure will be formed, providing auxiliary support with a certain strength for the positioning of the granulation end face of the granulation adjusting plate, ensuring the firmness and stability of the granulation adjusting plate erected in the chute.

[0007] Preferably, the elastic component includes a guide post vertically assembled on the back of the lining plate. The end of the guide post away from the lining plate movably penetrates through the chute and is locked and assembled with a retaining piece through a nut. A return spring is sleeved outside the guide post and between the retaining piece and the back of the chute. Among them, the elastic component is composed of a guide post, a nut, a retaining piece and a return spring. The guide post passes through the chute and a retaining piece is locked and installed at its end through a nut. The retaining piece cooperates with the back of the chute and a return spring is sleeved outside the guide post. When the conical protrusion is embedded in the receiving cavity formed by the first conical structure, the return spring is in a reset state. When the granulation adjusting plate is adjusted for lifting, the conical protrusion gradually disengages from the receiving cavity formed by the first conical structure of one granulation end face and finally enters the receiving cavity formed by the first conical structure of another granulation end face. During this process, the return spring is stretched and finally reset.

[0008] Preferably, a bushing coaxially extending into the material feeding cylinder is provided on the back of the lining plate. The outer wall of the bushing is fitted and matched with the inside of the material feeding cylinder. A second conical structure is provided at one end of the bushing away from the lining plate.

Preferably, by providing a bushing extending into the plastic cylinder on the back of the lining plate, the sealing performance of the transition of the material from the material feeding cylinder to the granulation adjusting plate can be further ensured. Since the granulation adjusting plate needs to be adjusted for lifting to replace the granulation end face, the gap between the two is sealed by the pad-mounted auxiliary support member. The bushing ensures the sealing effect, and the setting of the second conical structure helps the material to be transported and transitioned from the material feeding cylinder to the auxiliary support member.

[0009] Preferably, a first positioning groove for accommodating one end of the return spring is provided around the penetration of the guide post on the back of the sliding groove, and a second positioning groove for accommodating the other end of the return spring is formed on the side of the retaining piece away from the nut. Among them, the first positioning groove and the second positioning groove respectively provide positioning accommodation cavities for the two ends of the return spring, ensuring the firm and stable sleeving of the return spring outside the guide post, which helps to extend the service life of the elastic component.

Among them, the vertical plates are distributed in the vertical direction, and a plurality of granulation plates with equal areas are fixedly installed on the front of the vertical plate at equal distances along the length direction of the vertical plate by screws. Preferably, the surrounding plates preset on the front of the vertical plate and integrally connected with the vertical plate help the positioning and installation of the granulation plates, and the granulation plates with a detachable structure help the subsequent replacement or maintenance of the granulation plates. At the same time, the selection range of the particle size is further increased.

[0011] Therefore, the utility model has the following beneficial effects: By arranging a sliding groove at the output end of the feeding cylinder and slidingly assembling a granulation adjusting plate in the sliding groove, with the help of a plurality of granulation end faces with different granulation hole diameters arranged on the granulation adjusting plate, and in cooperation with the driving mechanism and the guiding mechanism, the granulation end faces with different granulation hole diameters can be respectively aligned with the output end of the feeding cylinder to meet the granulation requirements of different particle sizes of phosphogypsum.
