Take the basic process of squeezing oil. In the screw press, the press take the oil process can be divided into three stages Henan oil press, the feed (pre-press) segment, the main press section (the oil section), into the cake segment (weight and drain section) . Feed section: virgin material in the feed section began squeezed tight, exhaust air and a small amount of water, plastic deformation to form a "muffin", and start the oil. High oil and fuel in the compression phase begins feed oil. Note that easy to produce a back pressure in the feed zone, should take measures to force feeding and pre-press molding, to overcome the "back feed." Main press section: This stage is the formation of a large number of high-pressure oil discharge stage. Since then pressing bore space quickly on a regular basis to reduce the volume, pressing the material is strongly pressed between the pellets begin to coalesce, virgin material in the virgin bore a continuous porous material rather loose, a lot of oil discharged, while virgin material but also because of the spiral interrupted, pressing bore scraping force, pressing cage angular shearing caused by the material layer speed difference displaced fracture, mixing phenomenon, so the oil continues to open, conducive to the rapid drain grease. Into the cake segment: virgin material in the segment has been formed into a cake cake Henan watt massive press brand, was almost the whole propulsion, and thus have a greater resistance to compression, at this time of tile cake compressibility has not large, but still maintain a high pressure in order to drain the oil without being sucked back. Finally discharged from the shoe press cake, the phenomenon will increase in size due to the elastic expansion effect appears. Press cylinder squeeze cage structure: it includes a shell pressed cage, cage bars, juice bars circle, pressing ring, the cake ring, compression nut and the housing and connected to the oil pan and the like. Squeeze cage with ductile iron casing, the upper and lower price two Henan oil press, with 10 bolts as a whole. By pressing the middle of the cage has a flat round shell key to fixing ring and pressing circle cage bars. Squeeze cage front is a big circle cage bars, 16 bars and a pressing locking cage bars are arranged in a circular ring firmly pressing strip circle. Each cage bars have flat sides and the adjacent side of the gap formed pressed longitudinal flow of oil gap. In the ring end face of cage bars opened by pressing circle 220 radial oil grooves, groove depth of about 0.4 ~ 0.7mm. After pressing the cage segment is 14 laps virgin, where 1 to 6 and 8 to 14, pressing ring structure is basically the same, the inner serrated special curved, its role is not formed in the so-pressed smooth bore Surface to increase parison in virgin bore friction and flip degree Henan press equipment, the inner circle of the 7th virgin no sawtooth curve. One end face of each ring is pressed flat, the other side has the same ring with cage bars opened 220 radial tank, flat end face of the fuel tank and adjacent pressing ring with the formation of the oil flow gaps. Pressing circle and circle cage bars below are splined to the middle and lower squeeze cage housing with flat keys. Cage bars, pressing ring, cage bars lap with 20 high-quality carbon steel, and carburizing, quenching. After heat treatment, surface hardness of HR56-62, with high wear resistance.
