DISPOZITIV ROTATIV PENTRU EXTRACȚIA ULEIULUI DIN SEMINȚE OLEAGINOASEROTARY DEVICE FOR EXTRACTING OIL SEED OIL

Invenția se referă la un dispozitiv rotativ pentru extracția uleiului din semințe oleaginoase.The invention relates to a rotary device for extracting oil from oilseeds.

Sunt cunoscute diverse dispozitive de extracție a uleiului din semințele oleaginoase care au la bază extracția cu ajutorul șnecurilor (US 2009/0126583 Al). Dezavantajul lor constă în exercitarea unei presiuni care nu are aceeași valoare în toată masa de semințe supusă presării. Lipsa unei presiuni uniforme determină o extracție cu un randament redus. Un alt dezavantaj îl reprezintă întreruperea ciclului de extracție pentru evacuarea șrotului.Various oil extraction devices from oilseeds are known to be based on screw extraction (US 2009/0126583 Al). Their disadvantage is the application of a pressure which does not have the same value in the whole mass of seeds subjected to pressing. The lack of a uniform pressure causes an extraction with a low yield. Another disadvantage is the interruption of the extraction cycle for the evacuation of the meal.

Problema tehnică pe care o rezolvă invenția constă în utilizarea, pentru extracția uleiului prin presarea mecanică a semințelor, unui anumit tip de poanson și a două semicupe montate pe două discuri cu axele de rotație înclinte. Poansonul, de o formă constructivă complexă, are la bază o formă, generată prin rotirea în jurul axei de simetrie a unei curbe evolventice pe un cerc, care asigură presarea semințelor și angrenarea cu suprafețele celor două semicupe iar la vârf o formă, generată prin rotirea în jurul axei de simetrie a unei curbe parabolice pe un cerc, care asigură o presiune constantă în toată masa de semințe supuse presării și amplifică lucru mecanic care se exercită asupra semințelor. Semicupele prezintă la interior două forme, una generată prin rotirea în jurul axei de simetrie pe un cerc a unei curbe evolventice și una generată prin rotirea în jurul axei de simetrie a unei drepte pe un cerc.The technical problem solved by the invention consists in the use, for the extraction of the oil by mechanical pressing of the seeds, of a certain type of punch and of two half-cups mounted on two discs with inclined axes of rotation. The punch, of a complex constructive shape, is based on a shape, generated by rotating around the axis of symmetry of an evolutionary curve on a circle, which ensures the pressing of the seeds and engagement with the surfaces of the two halves and at the top a shape, generated by rotating around the axis of symmetry of a parabolic curve on a circle, which ensures a constant pressure throughout the mass of seeds subjected to pressing and amplifies mechanical work that is exerted on the seeds. The half-cups have two shapes inside, one generated by rotating an evolutionary curve around the axis of symmetry on a circle and one generated by rotating a line on a circle around the axis of symmetry.

Dispozitivul pentru extracția uleiului elimină dezavantajele soluțiilor cunoscute și rezolvă problema tehnică propusă, prin aceea că, prin utilizarea semicupelor, montate pe cele două discuri cu axe înclinate, care se unesc și împreună cu o placă formează o cavitate de presare în care intră un poanson de o formă constructivă complexă, se asigură presarea uniformă și antrenarea discurilor în mișcare de rotație pentru a aduce în fața poansonului următor o altă cavitate umplută cu semințe. Prin continuarea rotirii discurilor, datorită înclinării axelor de rotație, are lor desfacerea semicupelor și se permite evacuarea ușoară a șrotului pe un jgheab înclinat către o magazie.The oil extraction device eliminates the disadvantages of the known solutions and solves the proposed technical problem, in that, by using half-cups, mounted on the two discs with inclined axes, which join and together with a plate form a pressing cavity into which enters a punch of a complex constructive form, uniform pressing and driving the rotating discs are ensured in order to bring in front of the next punch another cavity filled with seeds. By continuing to rotate the discs, due to the inclination of the axes of rotation, it has the opening of the half cups and allows easy evacuation of the grindstone on a gutter inclined to a warehouse.

Dispozitivul pentru extracția uleiului din semințe oleaginoase, conform invenției, prezintă următoarele avantaje:The device for extracting oil from oilseeds according to the invention has the following advantages:

asigură presiunea necesară spargerii semințelor în vederea realizării extracției uleiului conținut de semințe;ensures the necessary pressure to break the seed in order to extract the seed oil;

asigură un regim de lucru continuu;ensures a continuous work regime;

se asigură presiuni uniforme de extracție în toată masa de semințe supuse extracției prin utilizarea poansonului cu cele două suprafețe;uniform extraction pressures are ensured throughout the seed mass subjected to extraction by using the punch with the two surfaces;

cele două semicupe pot fi curățate sau înlocuite cu ușurință în cazul colmatării;the two half-cups can be easily cleaned or replaced in case of clogging;

- piesa cu rol de sită asigură trecerea uleiului spre rezervorul de colectare și poate fi înlocuită sau curățată cu ușurință dacă apare colmatarea ei;- the sieve part ensures the passage of oil to the collection tank and can be easily replaced or cleaned if it becomes clogged;

se asigură o mai bună separare a uleiului de șrot;a better separation of the grinding oil is ensured;

- reducerea timpului de extracție și creșterea randamentului de extracție;- reduction of extraction time and increase of extraction efficiency;
