Technical Field

The invention belongs to the field of oil presses, and particularly relates to a double-screw multi-oil-port oil press.

Background

The screw type oil press is mainly used for oil presses for individual household processing. The product belongs to a hydraulic full-automatic oil press, has low yield, and is simple and convenient. When the oil press is in operation, the processed oil enters the pressing cavity from the hopper. The existing spiral oil press has the advantages of simple operation, simplicity, convenience, high oil yield, low pressing cost, pure oil product, rich nutrition, optional raw materials, safety, reassurance and the like.

However, the conventional screw type oil press has the following problems:

1. the oil outlet is easily blocked by oil residue entering the oil outlet under the action of pressure due to the fact that pressure generated by the movement of the oil material pushed by the screw is large.

2. The oil product flowing out of the oil outlet is doped with more dregs due to higher internal pressure.

3. The oil residue from the oil press slag outlet typically carries more oil.

The existence of the above problems can greatly affect the oil pressing efficiency of the oil press and the quality of oil products.

The invention designs a double-screw multi-oil-port oil press to solve the problems.

When the side walls of the movable groove A14 meet the cleaning blocks 52, the four cleaning blocks 52 on the slide block A50 just enter the range of the movable groove B16 on the inner wall of the movable groove A14 and do not form an obstacle to the continuous rotation of the cylinder 10. With the continuous rotation of the cylinder 10, when the sliding block a50 is opposite to the new oil outlet a13, the two inclined planes B51 on the sliding block a50 are respectively and instantaneously abutted against the two inclined planes a15 on the new movable groove a14 under the reset action of the spring a54, and the four cleaning blocks 52 on the sliding block a50 instantaneously enter the four holes of the filter screen 65 in the new oil outlet a13 and push the oil dregs blocked in the four holes of the filter screen 65 into the cylinder 10.

Meanwhile, the cam 9 fixedly connected with the fixed plate 7 through the fixed shaft 8 is in sliding fit with the four pressing rods 57, the tail ends of the four pressing rods 57 sequentially interact with the outer edge surface with the smallest radius on the cam 9, and the four pressing rods 57 respectively drive the corresponding sliding blocks B56 to slide in the corresponding sliding grooves A37 in a reciprocating mode under the circumferential sliding effect of the outer edge surface of the cam 9. When the sliding block B56 is opposite to a plurality of oil outlet holes B17 in the lowest end range on the side wall of the cylinder 10, the abutting rod 57 on the sliding block B56 is just abutted against the outer edge surface of the minimum radius on the cam 9, and the sliding block B56 opposite to the oil outlet hole B17 is contracted in the corresponding sliding groove A37 under the action of the corresponding two springs B58.

The fried oil is added into the space between the cylinder 10 and the spiral plate 40 from the funnel 28, the oil is moved by the spiral plate 40 rotating with the taper rod 30 from the conical surface A33 to the conical surface B36, because the pitch of the spiral plate 40 is gradually reduced along the axial movement direction of the oil, the oil is gradually squeezed by the reduction of the space between the spiral plate 40 and the inner thread sleeve 59 when the oil is driven by the spiral plate 40 to move axially, the oil in the squeezed oil is gradually squeezed out, the squeezed oil is firstly leached out from the oil outlet holes A13 in the lowest end range on the cylinder 10 under the action of gravity and flows into the corresponding container through the oil receiving hopper A55.

As the oil is drained from the oil outlet holes a13 located in the lowermost range of the cylinder 10, the dregs flowing along with the oil may block the four holes of the corresponding strainer 65 in the oil outlet holes a13, and if the strainer 65 blocked by the dregs is not cleaned in time, the oil is drained, and the oil extraction efficiency is lowered. Slider A50 drives four clearance pieces 52 in proper order on the drum 10 wall in whole oil outlet B17 in the four holes of filter screen 65 and will block up in the dregs top income drum 10 in the four holes of filter screen 65 to the realization is to the dregs of four downthehole jam of filter screen 65 effectively clear up fast, thereby guarantees oil outlet A13's the efficiency of producing oil. Meanwhile, the oil drained through the oil outlet A13 is guaranteed not to carry dregs, and the quality of the oil drained at the oil outlet A13 is improved.

As the oil is driven by the spiral plate 40 to continue to move axially, when the oil reaches the space at the oil outlet holes B17 in the lowermost range in the cylinder 10, the oil is further squeezed to further leach more oil, and the oil enters the corresponding container through the oil outlet holes B17 in the lowermost range in the cylinder 10 and the oil receiving hopper a55 under the action of gravity. Because any one sliding block B56 on the taper rod 30 is quickly contracted in the corresponding sliding groove A37 under the action of the corresponding two springs B58 and the cam 9 when the plurality of oil outlet holes B17 in the lowermost range in the cylinder 10 are opposite, and the space of the plurality of oil outlet holes B17 in the lowermost range in the cylinder 10 is quickly increased to a certain extent, the extrusion force received by the oil at the plurality of oil outlet holes B17 in the lowermost range in the cylinder 10 is quickly reduced, the oil at the plurality of oil outlet holes B17 in the lowermost range in the cylinder 10 is ensured not to be pressed into the oil outlet holes B17 due to the overlarge extrusion force, the oil outlet holes B17 are prevented from being blocked by dregs to reduce the efficiency of the oil outlet holes B17, meanwhile, because the oil is further compressed by the conical surface A33 and the spiral plate 40, the oil is tightly extruded and bonded together, and the oil extruded and bonded together basically can not generate scattered dregs, so that the oil outlet B17 is not blocked and the oil drained from the oil outlet B17 is not carried with dregs, thereby ensuring the quality of the oil drained from the oil outlet B17.

As the oil continues to move axially by the screw plate 40, the oil is further pressed and bonded together, and the oil is pressed more tightly. When the pressed oil is pressed tightly by the conical surface A33 of the taper rod 30 to enter the range of the cylindrical surface B35, the oil is further pressed again along with the further movement of the oil, and final oil residue is formed and discharged through the annular space between the internal thread sleeve 59 and the taper rod 30.

When the oil is driven by the spiral plate 40 to move in the conical surface B36, the oil is further extruded by the spiral plate 40 with the further reduced pitch, the oil remained in the oil is fully extruded out of the oil, and the extracted oil is drained out through the oil outlet holes C62 circumferentially and densely distributed on the inner wall of the conical part 60 of the internal thread sleeve 59, the annular oil cavity 61 and the oil outlet holes D63 circumferentially and densely distributed on the outer wall of the cylindrical part 66 of the ring sleeve A3 and enters the container through the oil receiving hopper B64.

The oil content in the oil residue from the internal thread sleeve 59 is a little remained, thereby ensuring that the oil residue does not influence the oil yield of the oil due to the oil content.

After the oil residue comes out of the internal thread sleeve 59, the size of a gap between the cylindrical part 66 of the internal thread sleeve 59 and the conical surface B36 of the taper rod 30 can be adjusted according to the amount of residual oil in the oil residue, if the oil residue contains more oil, the internal thread sleeve 59 axially moves relative to the cylinder 10 by rotating the internal thread sleeve 59, the conical part 60 of the internal thread sleeve 59 is close to the conical surface B36 of the taper rod 30, so that the gap between the conical surface B36 and the conical part 60 of the internal thread sleeve 59 is gradually reduced, the oil can be subjected to larger extrusion force in the process of space movement between the internal thread sleeve 59 and the conical surface B36, the residual oil in the oil is squeezed out, the oil residue formed by the oil is ensured not to carry oil basically when coming out of the internal thread sleeve 59, and the oil yield of the oil is improved. If the oil comes out from the internal thread sleeve 59 relatively difficultly, then, through reverse rotation of the internal thread sleeve 59, the internal thread sleeve 59 drives the conical part 60 to be far away from the conical surface B36 of the taper rod 30, so that the space between the conical part 60 of the internal thread sleeve 59 and the conical surface B36 of the taper rod 30 is increased, the gap between the conical surface B36 and the conical part 60 of the internal thread sleeve 59 is gradually increased to a proper size, the oil can be ensured to smoothly come out from the internal thread sleeve 59 and simultaneously can not carry oil, and the oil extraction efficiency of equipment and the oil extraction rate of the oil are improved.

In conclusion, the beneficial effects of the invention are as follows: according to the invention, the four cleaning blocks 52 arranged at the tail end of the sliding block A50 clean dregs blocked by the filter screen 65 in the oil outlet A13 of the cylinder 10, so that the oil outlet A13 is always smooth, and the oil pressing efficiency is improved.

According to the invention, four sliding blocks B56 which slide on the taper rod 30 in the radial direction do not extrude oil at the oil outlet B17 at the lowest end under the action of the cam 9, so that the oil drained from the oil outlet B17 is ensured not to carry dregs, the quality of the squeezed oil is ensured, and the oil outlet quality is improved.

When the oil finally forms oil residues and is extruded out of the internal thread, the oil residues in the oil residues are further extruded and are drained through the oil outlet holes C62 and the oil outlet holes D63 on the internal thread sleeve 59, so that the drained oil residues are ensured not to carry oil, and the oil outlet efficiency of the oil is improved to a certain extent.
