Description

TECHNICAL FIELD

[0001] The utility model relates to phosphogypsum processing technical field especially is phosphogypsum light aggregate granulating device. BACKGROUND

[0002] Granulation is a common treatment method of phosphogypsum, and various granulators are currently used to granulate phosphogypsum. For example, the Chinese patent with the authorization announcement number CN218077767U discloses a phosphogypsum light aggregate granulating device, which includes a cylindrical barrel. A spiral shaft is arranged inside the barrel. A main drive device located at one end of the barrel drives the spiral shaft to rotate. An inlet is arranged above the barrel on the side close to the drive device. The other end of the barrel forms an outlet. A support frame is arranged inside the barrel at the outlet end. One end of the spiral shaft is installed on the center hole of the support frame, and the other end penetrates through the side wall of the barrel and is connected with the main drive device. The outlet of the barrel is provided with a mounting plate. The granulating die can be replaced and installed on the mounting plate. The granulating device has the following defects: the existing phosphogypsum light aggregate granulating device sets a mounting plate for the replacement and installation of the granulating die at the outlet of the barrel to meet the production needs of phosphogypsum light aggregate particles of different particle sizes. In actual use, although the granulating die can be guided up and down through the window arranged on the support platform to achieve convenient disassembly and assembly, the sealing performance of the granulating die in the window cannot be guaranteed, which affects the granulating and forming effect. In addition, the granulating die needs to be lifted for disassembly and assembly, which cannot be replaced quickly. SUMMARY

[0003] The utility model provides a phosphogypsum light aggregate granulating device, which can quickly replace the granulating die, is convenient to disassemble and assemble, and can guarantee the butt joint sealing effect of the hole die and the output end of the screw extrusion granulator.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: A phosphogypsum lightweight aggregate granulation device of this utility model includes a workbench, and a pelletizing mechanism, a template switching mechanism, and a screw extrusion granulator sequentially installed on the workbench from left to right. A discharge space for the template switching mechanism to be suspended is reserved on the workbench between the pelletizing mechanism and the screw extrusion granulator. The template switching mechanism includes two support seats fixedly installed on the workbench and respectively located on both sides of the discharge space, a fixed rod fixedly mounted between the two support seats, and a mounting frame coaxially and movably mounted on the fixed rod. The mounting plate has several holes arranged in a circular array. The pelletizing mechanism includes a base plate and a reduction motor mounted on the base plate via a frame, and a rotary cutter connected to the output end of the reduction motor via a shaft. Two parallel guide rails are fixedly mounted on the top of the base plate, both distributed along the length of the base plate. Sliders are slidably mounted on both guide rails. The frame is fixedly mounted on the top of the two sliders. A cylinder for sliding drive of the frame is provided between the two guide rails. A pressure plate is welded to the frame and located around the output end of the reduction motor via several connecting frames.

[0005] Preferably, the assembly frame includes a sleeve for coaxially mounting the mounting disc. Both ends of the sleeve have end plates, and several sliding rods are provided between the two end plates and outside the sleeve for limiting the sliding movement of the mounting disc. The sleeve is rotatably mounted on the outside of the fixed rod via bearings. The assembly frame, acting as a connector between the mounting disc and the fixed rod, ensures the secure and stable mounting of the mounting disc on the fixed rod. Specifically, the rotatable sleeve mounted on the fixed rod via bearings allows the mounting disc to rotate, thus fulfilling the die switching function. The several sliding rods between the two end plates allow the mounting disc to move axially along the fixed rod, thereby cooperating with the pressure plate to ensure the alignment and pressing of the die with the output end of the screw extrusion granulator, ensuring a tight seal between the two.

[0006] Preferably, several of the aforementioned dies are fixedly mounted on the left side of the mounting plate using screws. The dies are secured within the mounting plate by a series of screws arranged in a circular array, allowing for easy disassembly and replacement. In actual use, only one die, connected to the output end of the screw extrusion granulator, is in active use, while the remaining dies on the mounting plate are spare dies. Operators can arrange and configure the spare dies according to usage requirements to facilitate quick replacement of dies in subsequent production.

[0007] Preferably, the mounting plate has a recessed groove on the right side for the die to connect with the output end of the screw extrusion granulator, and both the recessed groove and the right side of the pressure plate are fitted with rubber rings. The rubber rings ensure a tight seal between the two sides of the die under the pressure of the pressure plate.

[0008] As preferred, the periphery of the mounting disc is provided with a plurality of handle holes arranged in a ring array, and an anti-skid bushing is embedded in each of the handle holes. The handle hole matched with the anti-skid bushing helps the operator to rotate the mounting disc.

[0009] Therefore, the utility model has the following beneficial effects: the mounting disc is coaxially arranged on the fixed rod, the hole die on the mounting disc can be replaced quickly, and the mounting disc is convenient to disassemble and assemble; in addition, under the action of the cylinder, the rack is slidably assembled on the base plate, the rotating cutter driven by the reduction motor is connected with the pressing plate, and the sealing effect of the hole die and the output end of the screw extrusion granulator and the granulation effect can be ensured.
