Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 3, a press mechanism for oil press, the press cylinder 2 comprising jack-in-the-box 1 and coordinate with it, described press cylinder 2 sidewall is provided with out oil groove 21, press cylinder 2 tail end is provided with slag notch 22, and described press cylinder 2 is divided into the conveyor chamber 23 of leading portion and the crushing chamber 24 of back segment; Described crushing chamber 24 diameter is less than conveyor chamber 23 diameter; Described jack-in-the-box 1 is divided into the transportation section 11 of leading portion---the conveyor chamber 23 of corresponding press cylinder 2, the squeeze section 12 of back segment---the crushing chamber 24 of corresponding press cylinder 2, the major diameter of thread of described jack-in-the-box 1 diminishes from front to back gradually in transportation section 11, keep constant after entering squeeze section 12, the bottom diameter of described jack-in-the-box 1 becomes large from front to back gradually, and the pitch of jack-in-the-box 1---squeeze section 12 is less than transportation section 11; The conveyor chamber 23 of described press cylinder 2 is the regular polygon cavity volume with tapering, and the change of its tapering is corresponding with the transportation section 11 of jack-in-the-box 1.
The present invention is diminished from front to back gradually by the major diameter of thread of transportation section 11 and bottom diameter becomes the space that large two kinds of modes reduce transportation section 11 and conveyor chamber 23 inwall from front to back gradually, squeezing space is made to diminish faster, then transportation section 11 is transitioned into squeeze section 12 quickly, and due to the major diameter of thread of squeeze section 12 invariable, but it is more much smaller than the major diameter of thread of transportation section 11, like this, crushing chamber 24 diameter of press cylinder 2 can be significantly smaller than conveyor chamber 23 diameter, then jack-in-the-box 1 and press cylinder 2 just can design more smaller and more exquisite than prior art.
The feeding mouth of material particles on press cylinder 2 drops in the flight pitch in transportation section 11, advanced by the rotation of jack-in-the-box 1, realize carrying the extruding of material particles, after entering squeeze section 12, the major diameter of thread of jack-in-the-box 1 keeps constant, bottom diameter still becomes large gradually, squeezing space between jack-in-the-box 1 and press cylinder 2 progressively diminishes, squeezing material is stressed becomes large gradually, what be squeezed is progressively complete, after squeezing, oil flows out from going out oil groove 21, and press residue is extruded discharge from slag notch 22.
The pitch of jack-in-the-box of the present invention---squeeze section 12 is less than transportation section 11, the bottom diameter of jack-in-the-box 1 is coordinated to become large gradually, also make material to be squeezed space less, thus Milling Efficiencty is higher, on equal length, higher when oil yield is more constant than pitch, or, for reaching identical oil yield, structural design of the present invention can be shorter and smaller than prior art.
The conveyor chamber 23 of press cylinder 2 of the present invention is the regular polygon cavity volume with tapering, and the change of its tapering is corresponding with the transportation section 11 of jack-in-the-box 1; Like this, increase the radial frictional force of conveyor chamber, the material particles be transferred can not be followed jack-in-the-box 1 and be carried out circular motion, and can only move along the screw thread direction of propulsion of jack-in-the-box, thus effectively promote the axial advance of material, material particles can be carried down swimmingly.
As the preferred embodiment of the present invention, the screw thread place of the transportation section 11 of described jack-in-the-box 1 has breach 13.The space that can hold material particles due to squeeze section 12 is significantly smaller than the space that transportation section 11 can hold material, when fltting speed is the same, the amount that material particles squeezing advances is significantly smaller than the amount that conveying advances, when material loads too fast or too much, at the screw thread place design breach 13 of jack-in-the-box transportation section 11, the amount that mass transport advances can be reduced, simultaneously, if material particles can not forward impelling time, can be return by breach backward, prevent stuck, make feeding and squeezing reach a dynamic equilibrium; And breach can also carry out after cutting attenuates to the material particles in transportation section 11, then enter into squeeze section 12 and squeeze, improve oil yield.
