The working process of the spiral extrusion dewatering machine is as follows: the unobstructed pump pumps the material into the machine body, and the material is accelerated and dropped under the action of the vibration motor. At this time, through power transmission, the extrusion screw gradually pushes the material forward of the machine body, and the dehydrated material is pushed forward at a speed of 20-60 revolutions per minute by the extrusion screw placed in the screen. At the same time, the pressure at the leading edge is continuously increased, forcing the moisture in the material to be squeezed out of the screen under the action of pressure and filtration, and flow out of the drainage pipe. The operation of the extruder is continuous, and the material is continuously pumped into the body. The pressure at the leading edge increases continuously. When it reaches a certain level, the discharge port is pushed open to extrude the extrusion port, achieving the purpose of extruding the material. In order to control the speed and moisture content of the discharge, the counterweight block below the main engine can be adjusted to achieve a satisfactory and appropriate discharge state.
