Fuel-displaced anti-blocking oil press in a kind of
Technical field
The utility model relates to oil press technical field, relates in particular to the Anti-blocking structure aspect of the interior oil discharge passage of the oil press structure of Domestic oil press.
Background technology
Interior fuel-displaced oil press, squeezing bar offers oil outlet or fuel-displaced seam, is provided with oil discharge passage in squeezing bar inside.When the oil of squeezing out flows in oil discharge passage, due to the effect of heat, there is Separation of Solid and Liquid, have accumulated slag phenomenon, cause interior oil discharge passage to block.
Summary of the invention
In sum, the purpose of this utility model is that the interior oil discharge passage solving existing oil press structure holds susceptible to plugging technical deficiency, and proposes a kind of interior fuel-displaced anti-blocking oil press.
For solving the technical problem that the utility model proposes, the technical scheme adopted is: fuel-displaced anti-blocking oil press in a kind of, include and squeeze cover and be located at the squeezing bar squeezed in cover, squeeze bar inside and be provided with oil discharge passage, the bar wall squeezing bar is provided with the oil outlet or fuel-displaced seam that communicate with oil discharge passage; It is characterized in that: in the oil discharge passage of described squeezing bar, be provided with Anti-blocking structure.
Described Anti-blocking structure is be inserted in oil discharge passage to rotate relative to squeezing bar the accumulated slag scraping member striking off oil discharge passage inwall accumulated slag.
Described accumulated slag scraping member is the scraper plate of the strip matched with oil discharge passage diameter, and scraper plate includes knife edge, and the another side that knife edge is relative is knife back limit, and knife back limit is provided with breach, and scraper plate one end is exposed outside squeezing boom end.
Described accumulated slag scraping member is the helical structure that diameter and oil discharge passage diameter match.
Described accumulated slag scraping member is inserted in oil discharge passage by squeezing bar feed end, and accumulated slag scraping member is at least inserted into and oil outlet or fuel-displaced seam corresponding position.
Described oil discharge passage is made up of the section of two sections of different-diameters, and the diameter being positioned at the section squeezing bar slag output end is relatively large, and two section junctions are formed with a ledge structure.
The protuberance of described ledge structure is acuter angles.
Described Anti-blocking structure is the thread groove be located on the inwall of oil discharge passage.
The conversion film that generates after the oil discharge passage surface of described squeezing bar is provided with antiseized chemistry or electrochemical treatments.
The beneficial effects of the utility model are: be provided with Anti-blocking structure in the oil discharge passage of squeezing bar of the present utility model, Anti-blocking structure can be relative to squeezing scraper plate that bar rotates or the accumulated slag scraping member that helical structure is formed, also can be ledge structure or thread groove, can also be accumulated slag scraping member and ledge structure or thread groove combining structure; In oil expression process, under the effect of power set, accumulated slag scraping member can rotate relative to squeezing bar, reaches the effect striking off oil discharge passage inwall accumulated slag, fuel-displaced anti-blocking object in realizing.The utility model structure is applicable to be suitable for vertical, tilting, horizontal oil press.

Detailed description of the invention
Below in conjunction with accompanying drawing and the preferred specific embodiment of the utility model, structure of the present utility model is further described.
Shown in Fig. 4, the utility model includes and squeezes cover 1 and be located at the squeezing bar 2 squeezed in cover 1, and squeeze bar 2 inside and be provided with oil discharge passage 21, the bar wall squeezing bar 2 is provided with the oil outlet 22 or fuel-displaced seam that communicate with oil discharge passage 21; Anti-blocking structure is provided with in the oil discharge passage of described squeezing bar 2.
The following various structures of Anti-blocking structure:
Structure one: Anti-blocking structure is be inserted in oil discharge passage 21 to rotate relative to squeezing bar 2 the accumulated slag scraping member striking off oil discharge passage 21 inwall accumulated slag, is inserted with oil expression process and rotates relative to squeezing bar 2 the accumulated slag scraping member 3 striking off oil discharge passage 21 inwall accumulated slag in the oil discharge passage 21 of also namely described squeezing bar 2.And accumulated slag scraping member 3 is the scraper plate of the strip matched with oil discharge passage 21 diameter, scraper plate includes knife edge, and the another side that knife edge is relative is knife back limit, knife back limit is provided with breach, scraper plate one end is exposed outside squeezing bar 2 feed end end, and scraper plate is monolateral scrapes slag, not easily blocks.
Structure two: adopt the helical structure that diameter and oil discharge passage 21 match, replaces the scraper plate in structure one, and structure two adopts accumulated slag scraping member to realize anti-blocking equally.The accumulated slag scraping member 3 of structure one and structure two is inserted in oil discharge passage 21 by squeezing bar 2 feed end, and accumulated slag scraping member is at least inserted into and oil outlet or fuel-displaced seam 22 corresponding position.
Structure three: be made up of the section of oil discharge passage 21 by two sections of different-diameters, the diameter being positioned at the section squeezing bar slag output end is relatively large, and two section junctions are formed with a ledge structure 23, and the protuberance of ledge structure 23 is acuter angles, thus form an Anti-blocking structure, so that grease is directly discharged.
Structure four: structure three combines with structure one or structure two Anti-blocking structure formed.
Structure five: with reference to shown in Fig. 5, the inwall of oil discharge passage 21 is provided with thread groove 211, thread groove 211 is positioned at the section inwall that oil outlet or fuel-displaced seam squeeze bar 2 slag output end partially, to increase the flow velocity of oil, prevents accumulated slag; That is to say that Anti-blocking structure is the thread groove 211 be located on the inwall of oil discharge passage.
Structure six: the conversion film generated after oil discharge passage 21 surface of described squeezing bar 2 is provided with antiseized chemistry or electrochemical treatments, conversion film is formed by after chemistry or electrochemical treatments, conversion film contributes to grease Accelerating Removal, also namely conversion film independently as a kind of Anti-blocking structure, also can form a kind of Anti-blocking structure with above-mentioned five kinds of textural associations.
