[0025] In an embodiment of the utility model, the communicating pipe 401 is fixedly connected with the pressure cylinder 402, one end of the communicating pipe 401 away from the pressure cylinder 402 is fixedly connected at the top end face of the drying cylinder 1, the inner wall of the pressure cylinder 402 is sleeved with the piston 403, the top end face of the piston 403 is rotatably connected with the threaded rod 404, one end of the threaded rod 404 away from the piston 403 is fixedly connected with the hand wheel 405.

[0026] The frame body 406 is fixedly connected at the outer wall of the pressure cylinder 402, the inner wall of the frame body 406 is slidably connected with the sliding block 407, the inner wall of the sliding block 407 is provided with the threaded groove 408, the threaded groove 408 is threadedly connected with the threaded rod 404, the side wall of the sliding block 407 is fixedly connected with the pull rod 409, the pull rod 409 is sleeved with the spring 410, one end of the spring 410 abuts against the sliding block 407, the other end of the spring 410 abuts against the inner wall of the frame body 406.

[0027] The rotating assembly 3 comprises the motor 301, the motor 301 is fixedly connected at the bottom end face of the drying cylinder 1, the output end of the motor 301 is fixedly connected with the rotating rod 302, the side wall of the rotating rod 302 is fixedly connected with the stirring rod 303, the motor 301 drives the rotating rod 302 and the stirring rod 303 to rotate, and the material in the drying cylinder 1 is crushed.

[0028] The side wall of the drying cylinder 1 is fixedly connected with the air inlet pipe 5, one end of the air inlet pipe 5 away from the drying cylinder 1 is fixedly connected with the fan 6, the side wall of the drying cylinder 1 is fixedly connected with the air outlet pipe 7, the outer wall of the air outlet pipe 7 is fixedly connected with the electromagnetic valve 8, the top of the feeding port 2 is sleeved with the cover body 10, the air outlet pipe 7 is connected with the external collecting device, the air pressure in the external collecting device is consistent with the air pressure in the drying cylinder 1.

[0029] Turning the handwheel 405 rotates the threaded rod 404, causing the piston 403 to move upward. This increases the sealing space within the pressure cylinder 402, reducing the air pressure inside the drying cylinder 1. The boiling point of water also decreases, leading to faster evaporation, improved drying efficiency, and shorter drying time. Lowering the air pressure allows drying to be completed at a lower temperature, reducing the risk of material decomposition or charring due to high temperatures, maintaining the physicochemical stability of dicalcium phosphate, and ensuring product quality. The air outlet pipe 7 connects to an external collection device, ensuring the air pressure inside the external collection device matches that inside the drying cylinder 1. When the solenoid valve 8 opens, the fan 6 slowly blows air into the drying cylinder 1, causing the airflow to carry water vapor which is then collected by the external collection device, achieving material... To dry the material, the solenoid valve 8 is closed, the external collection device is emptied, and the pull rod 409 is pulled, causing the sliding block 407 to move away from the threaded rod 404. This causes the external air pressure to push the piston 403 downward. At this time, the air pressure inside and outside the drying cylinder 1 is the same. The solenoid valve 8 is opened, and the fan 6 blows air forcefully into the drying cylinder 1, thereby blowing the dicalcium phosphate powder in the drying cylinder 1 into the air outlet pipe 7 and the external collection device, thus collecting the dicalcium phosphate powder. First, the atmospheric pressure is restored, and then the fan 6 is turned on to blow air forcefully into the drying cylinder 1. This can avoid material blockage or uneven conveying due to excessive pressure difference, and prevent the equipment from structural fatigue, seal damage, or mechanical component deformation due to sudden pressure changes, thereby improving the durability of the equipment.

A limit block 902 is fixedly connected to the inner wall of the connecting pipe 401, and a rubber sheet 903 is fixedly connected to the inner wall of the hinge plate 901. During the air extraction stage of the pressure cylinder 402, the airflow pushes open the hinge plate 901, allowing the airflow to enter the connecting pipe 401 normally. During the stage when the external air pressure pushes the piston 403 downward, the airflow pushes open the rubber sheet 903, causing the rubber sheet 903 to deform, allowing the airflow to enter the drying cylinder 1 normally. During the stage when the fan 6 blows the dicalcium phosphate powder, the hinge plate 901 prevents the dicalcium phosphate powder from entering the connecting pipe 401 and the pressure cylinder 402, avoiding powder accumulation that affects the normal movement of the piston 403, preventing inaccurate pressure regulation or piston 403 jamming caused by powder, and improving the operational stability of the equipment.
