Hydraulic oil press is the main oil plant essence oil refining equipment, domestic current widespread use of xj type hydraulic press, pre-press expeller xjy hydraulic oil press, and other small yield in 10 a 70 t/d, it covers an area of big, long conveying equipment, maintenance of the intensity of labor is big.A few small hydraulic oil mill imported from abroad,palm oil plant the price is high, the cost is large.In view of the trend of the development of the oil plant toward large-scale direction, in order to adapt to the demand of the market, combined with foreign squeezed oil hydraulic machine manufacturing technology, we design developed has reached the international advanced technology level of large hydraulic oil press, and has been applied in several large oil plant.Now will be small to introduce the design of the hydraulic oil press, usage, which is of reference to colleagues.
1 small design principle of hydraulic oil press
Small hydraulic press is mainly composed of reducer, rack, squeezer, pressing cage, oil residue ground dragon, etc.Oil by feeding ground dragon sent to hydraulic oil press press chamber, squeezer oil pushed forward at the same time, because of the pressing screw pitch increasing, bottom diameter narrowing, pressing formation pressure in the chamber to squeeze oil in the oil.Vats, cage on the plate is pressing bar between pad and gaskets, squeeze out the oil from the pressing bar gap discharge pressing chamber, by diesel ground dragon eduction.Bread from the squeezer shaft end.This press is 250 a 300 t/d production, squeezer compression ratio is large, dry cake residual oil below 14%, forming good bread, facilitate subsequent leaching.
2 feed control system design
Small hydraulic press is a continuous production automation equipment, we designed the feeding control system, as shown in figure 2.The system has two control circuit, a control circuit is made a sensor to control the feed hopper to maintain a certain level;Another control...
