[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides an improved phosphogypsum screw conveyor, such as Figure 1-Figure 4 As shown, it includes a feeding barrel 1, one end of which is equipped with a motor 4, the other end of which is connected to a discharge pipe 11, a rotating shaft 2 is installed inside the feeding barrel 1, a spiral push piece 3 is installed on the outer wall of the rotating shaft 2, the output shaft of the motor 4 is connected to one end of the rotating shaft 2, the top of the discharge pipe 11 is connected with an air pipe 6, and the surface of the spiral push piece 3 is equipped with a plurality of claw nail assemblies 8, the claw nail assembly 8 is mainly used to better push and stir the phosphogypsum, especially when dealing with sticky or easy-to-agglomerate phosphogypsum, the claw nail can effectively break the agglomeration to ensure that the material can be transported evenly and smoothly, the top of the end of the feeding barrel 1 away from the discharge pipe 11 is connected with a feed bin 5, the top of the feed bin 5 is connected with a receiving hopper 51, and the motor 4 provides power for the entire conveyor. When the motor 4 is started, it will drive the rotating shaft 2 to rotate, thereby driving the spiral push piece 3 to push the material, and the spiral push piece 3 will push the phosphogypsum material from the feed bin 5 to the discharge pipe 11.

[0023] In this embodiment, a cleaning port 13 is provided at the top of the feeding barrel 1, and a cover plate is hinged at the cleaning port 13 to facilitate manual cleaning.

[0024] Specifically, a support foot 12 is installed at the bottom of the feeding tube 1 to facilitate stable support of the feeding tube 1 .

[0025] Furthermore, the outer end of the air supply pipe 6 is connected to a compressed air machine, and an air intake pipe 61 is installed at one end of the air supply pipe 6 close to the discharge pipe 11. The air intake pipe 61 is a trumpet-shaped structure, and a flow equalizing plate 62 is installed at the outer end of the air intake pipe 61 to ensure uniform introduction of compressed gas.

[0026] Furthermore, a plurality of through holes 621 are provided on the surface of the flow equalizing plate 62 to ensure uniform airflow.

[0027] Furthermore, a vibration motor 7 is installed on the outer wall of the feeding barrel 1 to achieve vibration of the feeding barrel 1, which helps to reduce the adhesion of materials on the barrel wall and further improves the conveying efficiency.

[0028] Furthermore, the claw nail assembly 8 includes a sleeve 81, a stirring rod 82 is installed inside the sleeve 81, a stirring plate 83 is installed on the top of the stirring rod 82, and the bottom of the sleeve 81 is fixed to the spiral push plate 3 by a locking bolt 84 to prevent the phosphogypsum from coagulating during transportation.

[0029] Furthermore, the inner wall of the sleeve 81 is provided with an internal thread, and the bottom outer wall of the stirring rod 82 is provided with an external thread. The sleeve 81 and the stirring rod 82 are threadedly connected to facilitate the disassembly and installation of the stirring rod 82 and facilitate subsequent maintenance.

[0030] When the improved phosphogypsum screw conveyor of the utility model is used, first, the motor 4 is started, and the output shaft of the motor 4 drives the rotating shaft 2 to start rotating. The rotating shaft 2 drives the spiral push piece 3 to start rotating motion. The phosphogypsum enters the feed bin 5 from the receiving hopper 51, and then falls into the feeding barrel 1. As the spiral push piece 3 rotates, the phosphogypsum is gradually pushed toward the discharge pipe 11. In this process, the claw assembly 8 installed on the surface of the spiral push piece 3 begins to play a role. The stirring rod 82 and the stirring piece 83 in the claw assembly 8 stir the phosphogypsum, effectively breaking up the lumps in the phosphogypsum, and ensuring that the material can be transported evenly and smoothly. The phosphogypsum that has been stirred and pushed is finally discharged from the discharge pipe 11. During the discharging process, in order to prevent the material from being blocked at the discharge pipe 11, compressed air will be introduced into the air pipe 6. The compressed air is evenly blown into the discharge pipe 11 through the air inlet pipe 61 and the flow equalizing plate 62 to help clear possible blockages. At the same time, the vibration motor 7 installed on the outer wall of the feeding barrel 1 will produce micro-vibration to reduce the adhesion of materials on the barrel wall. If cleaning or maintenance is required after long-term use, it can be done through the cleaning port 13 at the top of the feeding barrel 1, where the hinged cover can be easily opened and closed.

[0031] Finally, it should be noted that the motor 4, vibration motor 7, etc. in this embodiment, the electronic components in the above parts are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively.
