The squeezing screw shaft of the new hydraulic oil press is composed of several squeezing screws and pitch rings sleeved on the shaft. Each screw has a certain pitch and depth, and the pitch of each screw on a shaft is gradually shortened from the inlet to the outlet, and the screw depth gradually becomes shallower, so that the volume of the press chamber is gradually changed from the inlet to the outlet. Decrease.
After the raw material enters the pressing chamber, it advances along the snail stage to the exit, and the pressure gradually increases, so that the oil is gradually squeezed out. A gasket is installed between the pressing cage and the sliver to form an oil gap. The crude oil flows out through this gap.
The new hydraulic oil press is a machine that continuously advances the raw material in the press chamber and extracts crude oil under the action of dynamic squeezing. In addition to the feed hopper, the press chamber is the main operating part, consisting of a press screw shaft and a cylindrical press cage. There are two types of single-stage pressing and double-stage pressing. The single-stage has only one horizontal pressing chamber, and the two-stage has an additional direct pressing chamber for pressing.
1. When there is too much feed in the initial stage of squeezing, the fried oilseeds can be slowly fed in, and the mill can be used to remove them repeatedly.
2. During the squeezing process, the material in the press chamber is cut off due to a large amount of material being fed and the press chamber is blocked by oil. Therefore, the feeding should be continuous and uniform. Once the blockage occurs, the power supply should be turned off immediately, the feeding should be stopped, the discharge plate should be opened, the screw shaft should be removed, the oil in the chamber should be removed, and the pressure should be re-squeezed.
The squeezing cage of the new hydraulic oil press is also equipped with a scraper. The scraper blade goes deep into the squeezing chamber and is aligned with each distance ring to prevent the embryo from slipping in the squeezing chamber, prevent the embryo from returning, and adjust the thickness of the cake. So as to correspondingly control the press chamber pressure and reduce the residual oil rate. In addition, the machine also has a cake-clamping mechanism that makes the surface of the slag cake smooth and clean, and is often accompanied by a steaming pan.
