oil processing principle structure
When press operation , after a good deal of oil squeezed from the hopper into the breech . Pressed by the screw to keep the embryo transfer so that the material in advance , be pressed . As the material of the embryo in the press virgin bore in the state of motion oil extraction out under conditions of high pressure pressing chamber , producing a great deal of friction between the embryo and the virgin material snails, embryos and virgin material breech , so friction can cause relative movement between the micro- parison material . On the other hand , due to the pressing screw root diameter is gradually thickening Park pitch is gradually reduced , so when pressing screw rotation , screw hard material embryos that can move forward , but also outward and upward while pressing screw thread close as the surface of the material layer is also pressed axis. Such virgin bore in each embryo particulate material , such as the speed is not the same direction, but also exist between the relative motion of particles . The heat generated by friction and the oilfield equipment process operation to meet the necessary heat helps to promote the parison thermal denaturation of proteins , destruction of the gel, to increase the ductility , while also reducing some of the oil to the viscosity tends to be precipitated , thus improved oil yield oil press , so there is oil squeezed out feed and discharge gap and the gap outflow of exhaust from the park.
