The transmission shaft 203 is connected to the inside of the top of the transmission cylinder 202 via bearings. A planetary gear differential is installed at the bottom of the transmission shaft 203. The planetary gear differential is a mechanical transmission device, mainly composed of a sun gear, planet gears, a planetary gear carrier 207, and a ring gear. Its core function is to adjust the speed difference between the output shafts through the rotation and revolution of the planet gears. When the input end of the planetary gear differential is fixed, the rotation of the planetary gear carrier 207 will drive the output end to generate... Rotating in the same direction, but at a slower speed, the spiral feeding centrifugal mechanism includes a discharge support shell 301, a spiral guide plate 302, a bottom sealing ring 303, and a screen 304. The discharge support shell 301 is fixedly sleeved on the top surface of the transmission cylinder 202. The spiral guide plate 302 is fixedly installed on the surface of the discharge support shell 301. The bottom sealing ring 303 is movably disposed on the top of the discharge rack 102. The screen 304 is fixedly installed on the top of the bottom sealing ring 303. Both the shape of the discharge support shell 301 and the shape of the screen 304 are frustoconical. The outer diameter of the upper surface of the discharge support shell 301 is smaller than the outer diameter of the lower surface of the discharge support shell 301, and the inner diameter of the upper surface of the screen 304 is smaller than the inner diameter of the screen.

The safety coupling is also called a torque limiter 114, a torsion limiter or a safety clutch. It is a component for coupling a driving machine and a working machine. The main function is overload protection. When the required torque exceeds the set value due to overload or mechanical failure, it limits the torque transmitted by the transmission system in the form of slipping. When the overload condition disappears, it automatically restores the connection. In this way, mechanical damage is prevented, and expensive downtime losses are avoided.

[0034] Working principle: In use, the driving motor 505 is started to drive the driving transmission wheel 506 to rotate, which drives the driven transmission wheel 507 to rotate through the transmission belt 508. When the driven transmission wheel 507 rotates, it drives the planetary gear carrier 207 on the surface of the planetary gear differential to rotate. Due to the structure of the planetary gear differential, when the fixed output end shaft 206 of the planetary gear differential is fixed, the rotation of the planetary gear carrier 207 drives the movable output end shaft 208 to rotate in the same direction, but at a slower speed. This makes the planetary gear carrier 207 drive the discharge support shell 301 to rotate relatively quickly, and the movable output end shaft 208 drives the feeding guide frame 307 through the transmission shaft 203, thereby driving the screen 304 to rotate relatively slowly, so as to ensure differential rotation between the discharge support shell 301 and the screen 304. Then the material is introduced through the feeding pipe 110. Due to the circular truncated cone structure of the feeding guide 307 and the screen 304, the material is moved downward away from the shaft center under the centrifugal action after entering the rotating feeding guide 307, until the material moves to the inside of the screen 304, the liquid in the material is thrown out under the centrifugal action, and the fixed material is intercepted in the screen 304. At the same time, due to the differential rotation between the discharge support shell 301 and the screen 304, the discharge support shell 301 with higher rotating speed drives the spiral guide vane 302 to form relative rotation in the screen 304, the rotating spiral guide vane 302 pushes the fixed material to continuously descend, and the material is continuously centrifuged to throw out the liquid in the process of descending. After most of the liquid in the material is discharged, the solid material is left, and then the solid material is pushed by the spiral guide vane 302 to pass through the discharge frame 102 and fall into the discharge hopper 112, and then is discharged along the discharge hopper 112, while the liquid is thrown out and discharged along the liquid discharge pipe 111 in the splash-proof cylinder 101. When cleaning the screen 304, the driving motor 505 is started to rotate the screen 304, water vapor is introduced into the steam joint 401, the steam enters the steam distribution pipe 403 and the bypass pipe 406 along the steam joint 401, the steam three-way pipe 402, and then is discharged along the main steam nozzle 404 and the cleaning nozzle 407. The steam discharged from the main steam nozzle 404 continuously washes the surface of the screen 304 in the opposite direction, and the steam sprayed from the bypass pipe 406 washes the surface of the steam distribution pipe 403 close to the screen 304. In work, the first sliding seal ring 306, the second sliding seal ring 308 and the third sliding seal ring 309 ensure that the discharge support shell 301, the feeding guide 307 and the bottom sealing ring 303 can rotate without entering the material from the gap, at the same time, the material entering the inside of the discharge support shell 301 can be centrifuged by the rotating self-cleaning fan 204 to avoid staying in the inside of the discharge support shell 301.
