Oil pressing device of axial compression spiral oil press

Abstract

The invention relates to an axial compression spiral oil press. According to the technology provided by the invention, the original radial compression that the outer diameter of the main shaft outer sleeve is changed from thin to thick to change the volume is changed into the same outer diameter of the main shaft outer sleeve from beginning to end. And axial compression is adopted. Therefore, rotation friction resistance is greatly reduced, matching power can be saved by 40%, extrusion of oil residues is reduced due to the fact that axial compression is changed, and the phenomenon of paste squeezing is avoided. And labor is saved when the shaft is pulled outwards.

Description

[0001] I. Technical Field: The device of the present invention belongs to the technical field of oil press equipment.

[0002] II. Background Art: The existing screw oil presses have six major disadvantages.

[0003] 1. The outer diameter of the main shaft jacket gradually thickens from the feed inlet to the discharge outlet, resulting in radial compression and increasing the frictional resistance.

[0004] 2. The oil material cannot be sprayed with steam. (To increase the activity of oil molecules)

[0005] 3. The oil yield is low, 10 - 11% for soybeans

[0006] 4. When the oil material passes through the tapered section, it is radially compressed, and too much oil residue is extruded.

[0007] 5. The oil material is easily stuck and immobile in the pressing chamber.

[0008] 6. It is too laborious to pull out the shaft outward.

[0009] III. Summary of the Invention: The purpose of the device technology of the present invention is to improve the radial compression to axial compression, so that the outer diameter of the main shaft jacket remains the same from beginning to end, greatly reducing the rotational frictional resistance.

[0010] The advantages after improvement are:

[0011] 1. Due to axial compression, the amount of extruded oil residue is reduced.

[0012] 2. Since an appropriate amount of moisture can be added, the oil yield can be increased by 3 - 4%.

[0013] 3. The structural process is simple and the cost is low.

[0014] 4. It is relatively labor-saving to pull out the shaft outward.

[0015] 5. The phenomenon of blocked pressing is avoided.

[0016] 6. 40% of the supporting power can be saved. Description of the Drawings: Figure 1 Structure diagram of the improved axial compression screw oil press.

[0017] IV. Specific implementation method:

[0018] The oil material enters the feeding section 4 and is pushed by the screw into the propulsion section 5, generating the first compression. Then it is extruded through the material-passing notch 8 of the material-blocking section 7 and enters the compression screw section 9. It then passes through the material-passing notch 11 on the material-blocking section 12 and enters the compression screw section 13, and is finally extruded from the discharge port 15 through the material-blocking section 14.

[0019] The baffle blocks 5, 6, and 10 shown in the figure are welded on later to make the oil material rotate radially to extend the compression and retention time in the squeezing chamber.
