Main functions of cylinders in screw press dewatering machines

Control of extrusion strength: the cylinder is usually connected with the control device (such as pneumatic device), according to the different materials to set the pressure (0.1-0.8mpa), auxiliary for the control of the squeezing process of extrusion strength, an effective solution to the phenomenon of uneven feeding of more or less phenomenon, the cylinder connected to the backpressure device for the normal state of closure, when the materials with the The back pressure device connected with the cylinder is normally closed, when the material is pushed forward with the spiral to form extrusion pressure, which is greater than the pressure set by the cylinder, the material pushes away the back pressure device and breaks the door out. This design helps to realize the back pressure control of the material compression, to avoid the slag suddenly dry and wet, to ensure the dehydration effect.

Assist in realizing solid-liquid separation: In the working process of the screw press dewatering machine, the adjustment of the cylinder is continuous to ensure that the material can be subjected to the appropriate squeezing force throughout the dewatering process, and the adhesion between the solid particles and the liquid is gradually reduced, and ultimately realize solid-liquid separation. The solid particles are pressed onto the wall of the spiral chamber and propelled by the spiral rotor to be discharged by the slag outlet, while the liquid flows out of the spiral chamber through the mesh of the screen.

Improve dewatering efficiency: Pressure can be optimized according to the nature of materials, output and other parameters to achieve the best dewatering effect. No need for manual guarding, the cylinder can automatically adjust the working state to ensure the stability and efficiency of the equipment operation.

Cognitive misconceptions about the cylinder: it is worth noting that often people often mistakenly think that squeezing dry and not dry depends entirely on the cylinder, in fact, this is a misunderstanding, the essence of the spiral press dewatering machine to achieve dewatering depends entirely on the special design of the spiral rotor, the cylinder backpressure device as an auxiliary function, when some materials through the spiral rotor extrusion, fully meet the requirements, the cylinder backpressure device can be in a The cylinder back-pressure device can be in a normally open state, no need to use.
