Description
Technical field:
The present invention relates to a kind of oil press, be specifically related to a kind of external tooth form and press circle and the helical axis that this presss for extracting juice encloses and the oil press that this helical axis is arranged are arranged.
Background technology:
At present, known screw oil expeller mainly is the turning effort that utilizes screw spindle, the volume of oil plant in pressing thorax dwindled gradually and is subjected to various resistances and the very big pressure that produces extracts oil.Oil plant is advancing the destruction that machine must handle to strengthen the oil plant cell through the high temperature steaming and frying technique that roll about embryo, 110 degree before go into pressing, and guarantees oil expression effect after the screw oil expeller oil plant is gone into press for extracting juice, so-called oil plant high temperature hot moulding technology that Here it is with this.For a long time, those skilled in the art press method raising oil expression effect, the reduction dry cake residual oil rate of gun pressure power by various increasings, but produce little effect.At present external popular oil plant low-temperature cold pressing technology already is at the early-stage in China, will steam the oil plant of frying without high temperature and advance machine and go into to press, and shortage satisfies its technological requirement to the screw oil expeller of oil plant cytoclasis function is then more difficult.
Known screw oil expeller presses thorax and presses bar by some, the strip that has corner angle and become circumferential arrangement and be the internal tooth round or directly adopt the ring gear axially-aligned to form.When though the helical axis rotation of working within it the time produces relative motion with it and since press for extracting juice spiral shell, the lining ring outer rim of helical axis screw press position (first segment presses spiral shell to final section and presses spiral shell) all do not have can with press the common tooth-shape structure that forms the stranding squeeze and destroy function of oil plant cell of thorax internal tooth.
Summary of the invention:
The objective of the invention is problem at above-mentioned existence provides a kind of external tooth form to press circle and the helical axis of this presss for extracting juice circle is arranged and the oil press of this helical axis is arranged, and improves the destruction function to the oil plant cell, thus the raising oil yield.
Above-mentioned purpose realizes by following technical scheme:
External tooth form is pressed circle, comprise and press the circle body, the outer rim of described press for extracting juice circle body has one group of heteromorphic teeth, the flank profil of described heteromorphic teeth is made up of a spirogyrate circular-arc tooth surface and the back of tooth, and the bending direction of described spirogyrate circular-arc tooth surface is opposite with the work direction of rotation of pressing the circle body from the tooth root to the tooth top.
Described external tooth form is pressed circle, and the number of teeth of described heteromorphic teeth is 4-20.
Described external tooth form is pressed circle, and the number of teeth of described heteromorphic teeth is even number.
Described external tooth form is pressed circle, and the root circle of described press for extracting juice circle body is cylindrical or truncated cone.
Described external tooth form is pressed circle, and the radius of curvature of described spirogyrate circular-arc tooth surface is not more than the root diameter of described press for extracting juice circle body, is not less than the tooth root of described heteromorphic teeth to the distance of tooth top.
Have above-mentioned external tooth form and press the helical axis of circle, comprise power transmission shaft, install one group on the described power transmission shaft and press spiral shell, described external tooth form is installed between at least one pair of adjacent described press for extracting juice spiral shell presses circle.
Described helical axis with external tooth form press for extracting juice circle passes through key connecting between described press for extracting juice circle and the described power transmission shaft.
Described helical axis with external tooth form press for extracting juice circle, the root circle of described press for extracting juice circle equates with the root circle of the contact site of the press for extracting juice spiral shell of its rear and front end.
Oil press with above-mentioned helical axis comprises the oil press body, and the press for extracting juice thorax the inside of described oil press body is provided with above-mentioned helical axis.
Described oil press with above-mentioned helical axis, the distance between the tooth top of the internal tooth of the tooth top of the heteromorphic teeth on the described helical axis and described press for extracting juice thorax is not more than 10mm.
Beneficial effect:
When helical axis work of the present invention is rotated, before external tooth form is pressed circle, back two ends are pressed and are postponed that oil plant continuously enters it and presses the tooth portion space that the thorax internal tooth forms under the resistance effect before the spiral shell, and it is capable of tooth top along its spirogyrate circular-arc tooth surface, because the characteristic that the tooth portion space that spirogyrate circular-arc tooth surface and press for extracting juice thorax internal tooth form dwindles from the tooth root to the tooth top gradually, oil plant further is subjected to increased pressure effect gradually, and the spirogyrate circular-arc tooth surface must produce role of tear to the oil plant cell under the pressured state with the relative motion of pressing the thorax internal tooth, to this kind compound action of oil plant cell, namely this kind of oil plant cell being rubbed with the hands the squeeze and destroy function is that present known screw oil expeller does not have.
