In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

An oil press device for pressing juglans sigillata oil is shown in fig. 1 and comprises a press main body 100 and a controller 400. The inside of squeezer main part 100 is equipped with presses storehouse 103, and one side top intercommunication filling tube 200, the material collection storehouse 301 of other side bottom through feed opening 202 intercommunication recovery unit 300. The bottom of the material collecting bin 301 is provided with a new inclined plate 302 which is inclined downwards and communicated with the waste collecting device, and the side wall of the material collecting bin is provided with an oil outlet pipe 304.

As shown in fig. 2, a screw 104 is horizontally arranged in the pressing bin 103, and a raised thread 105 is arranged on the screw 104 along the outer surface of the screw in a surrounding manner. One end of the screw 104 is rotatably connected with the pressing bin 103, and the other end of the screw is rotatably connected with the pressing bin 103, extends to the outside of the pressing bin 103, and is in driving connection with the driving output end of the driving device 102. The part of the screw 104 inside the pressing bin 103 is coaxially provided with: a press screw 1041 near the charging pipe 200 and an auxiliary screw 1042 near the feed opening 202.

The L1 is K1 is L2, and the value of the K1 ranges from 0.88 to 1.21. H1 ═ K2 ═ H2, the value range of K2 is: 0.58-0.72. The C1 is K3 is C2, and the value of the K3 ranges from 5.22 to 5.71. The pitch, the height and the length of the spiral are all in cm.

The length C of the part of the screw 104 inside the pressing bin 103 is C1+ C2, and the value range of C is 130-320. At this time, the distance between the press screw 1051 and the inner wall of the press bin 103 is the same as or similar to that of the existing screw press.

The applicant finds, through research, that one of the reasons that the conventional screw oil press can only press crisp walnuts but not iron walnuts lies in that: the walnut kernel has almost no viscosity, and the walnut material can be continuously pushed into the squeezing bin by the squeezing screw thread under the action of forced squeezing of the squeezing screw and the squeezing screw thread and the action of driving the material to move, so that a high-pressure squeezing area is formed, and grease in the walnut kernel is squeezed out. However, when the juglans sigillata is squeezed, the juglans sigillata kernels have high viscosity, so that the juglans sigillata materials can form mutual bonding effect. At this moment, the iron walnut materials that finish squeezing are hardly squeezed into the filling tube and are discharged by the simple drive action of squeezing the screw rod and squeezing the screw thread, and the iron walnut materials are piled up in the breaker in a large number this moment, and new materials can not get into, and the material of extrusion completion can not flow to lead to the relative material of extrusion screw to idle, the staff can only shut down the material in the clearance breaker this moment.

Through research of the applicant, the existing squeezing screw is divided into an auxiliary screw and a squeezing screw according to a specific proportion in the embodiment 1 of the application, the squeezing screw is provided with a squeezing thread, and the auxiliary screw with the relation among the thread pitch, the thread height and the squeezing thread in the embodiment 1 of the application is arranged on the auxiliary screw, so that the continuous feeding of the juglans sigillata materials into the squeezing section can be effectively realized, and the continuous squeezing of the juglans sigillata materials is realized.

Through comparative tests, the press thread described in example 1 of the present application is completely adopted as the thread of the screw, and although the situation of the crusher in no load is improved to some extent, the design requirement cannot be met, and the machine still needs to be stopped for cleaning materials for a plurality of times in the expected production period. By completely adopting the auxiliary thread in the embodiment 1 of the application as the thread of the screw, the material entering the squeezing bin can not realize good oil squeezing rate, a large amount of un-squeezed grease still exists in the oil residue, and the material waste is serious. And adopt the auxiliary screw and squeeze the screw that this application set up, not only can realize that the squeezer realizes squeezing in succession and need not shut down the clearance material in the production cycle of prediction, moreover the design requirement that the oil yield of squeezing of hickory nut reaches the breaker.
