Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil presses, in particular to an oil guiding and pressure transmitting device for a hydraulic oil press. Background Art

[0002] A hydraulic oil press is a common device used for oil pressing of oilseeds such as rapeseeds and sunflower seeds. It mainly includes a base. A filter cage is vertically arranged on the top of the base, and an oil collecting groove is formed on the base outside the filter cage. A plunger hydraulic press is vertically arranged above the filter cage. A plunger is fixed on the piston rod of the plunger hydraulic press, and the plunger slides up and down inside the filter cage. When pressing oil, the oilseeds are filled into the filter cage, and then the plunger hydraulic press is started to push the plunger downward to squeeze the oilseeds for oil pressing. The oil passes through the filter cage and is discharged into the oil collecting groove, and then collected. When the oil pressing is over, the oilseeds become oil cakes, and the density of the oil cakes reaches the maximum value. However, due to the gradually increasing density of the oil cakes, it is difficult for the oil in the internal oilseeds to flow out. The oil squeezed out from the oil cakes at the edge can still be discharged through the filter cage, while the oil squeezed out from the oil cakes in the center is blocked by the surrounding oil cakes and is difficult to discharge. This results in a high oil content rate in the overall oil cakes and a reduced oil yield, affecting the benefits. Based on this, the present application proposes an oil guiding and pressure transmitting device for a hydraulic oil press to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is achieved through the following technical solutions: An oil guiding and pressure transmitting device for a hydraulic oil press includes a pressure transmitting plate. A filter plate and a bearing plate are sequentially installed above the pressure transmitting plate. An oil cavity is concavely formed on the top surface of the pressure transmitting plate. A plurality of oil outlet channels arranged in a circumferential array are formed at the edge of the top surface of the pressure transmitting plate. All the plurality of oil outlet channels communicate with the oil cavity, and the oil outlet channels incline outward. A plurality of leakage liquid grooves are formed in multiple circles on the top surface of the bearing plate, and their positions are concentric. The cross-sectional shapes of the plurality of leakage liquid grooves in multiple circles are all trapezoidal.
