Description

[0002] The current traditional hydraulic oil pressing equipment generally adopts the working mode of single hydraulic cylinder driving single pressure-bearing bin. The traditional single-bin multi-cake peripheral oil discharge type oil press can realize multi-layer cake stacking and pressing, but the equipment uses a steel ring to block or a perforated cylinder to constrain the material, and the oil material package needs to be manually stacked layer by layer and relies on edge penetration to discharge oil. This process leads to the fact that the oil liquid in the center of the material needs to complete long-distance radial penetration to be separated, and when the applied pressure is insufficient, the oil liquid cannot be effectively separated, and when the pressure is too high, the oil passage is compressed and closed to form an oil seal effect, resulting in a decrease in oil discharge rate. More seriously, single pressing operation needs to be continued for more than 12 hours to complete oil liquid penetration, and the manual loading and unloading link occupies most of the working time, which greatly limits the production efficiency of industrialization.
