Description

Technical Field

[0001] The invention relates to the technical field of oil palm fruit oil pressing, in particular to a centrifugal oil palm fruit oil pressing machine. Background Art

[0002] Oil palm is an important tropical oil crop, mainly used to extract edible vegetable oil and industrial oil. The oil content of oil palm pulp is 46%-50%, and the oil content of kernel is 50%-60%. Compared with other oil crops, the oil yield per unit area is 5 times that of peanuts, 10 times that of rapeseed, and 12 times that of soybeans, so it is known as the "World Oil King". Since the activity of lipase in oil palm fruit is very high and it is very easy to increase acidity, it must be processed and extracted within 24 hours after harvesting to prevent the acidity from increasing and reducing the quality. Since my country's oil palm industry is still in its infancy, with small planting scale, wide dispersion, and low intensiveness, the existing large-scale palm oil processing production lines, equipment, supporting plant facilities and other facilities have high investment, and it is not suitable to build large-scale palm oil processing plants at present.

[0003] A centrifugal oil palm fruit oil press is disclosed in a public patent (publication number: CN204866223U). The oil palm pulp that has been sterilized, crushed and heated in advance is placed in a centrifugal barrel. The power device drives the centrifugal barrel to rotate, causing the oil palm pulp to rotate at high speed in the centrifugal barrel. Under the action of centrifugal force, the palm oil in the oil palm fruit (including some water, pulp impurities, etc., referred to as crude palm oil) is thrown out through the oil outlet hole on the centrifugal barrel. The palm oil after being thrown out is blocked by the arc cover plate and the front and rear baffles. Under the action of gravity, it gradually slides down and collects on the oil receiving plate, then flows out from the oil outlet, and is then manually collected in a container for further processing. In this application, the crude palm oil is thrown out by the action of centrifugal force, and then the residue in the barrel is manually taken out. This requires not only the collection of palm oil during the oil pressing process, but also the cleaning of residues such as kernels in the barrel. The steps are cumbersome.

[0004] Therefore, for the above-mentioned problem of raising, a centrifugal oil palm fruit oil press is badly needed now. Summary of the invention

[0005] The object of the present invention is to provide a centrifugal oil palm fruit press to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A centrifugal oil palm fruit oil press comprises a workbench for support, the workbench comprises a stirring mechanism arranged on the top and a discharging mechanism arranged on the bottom, the stirring mechanism comprises a crusher and a rotating assembly arranged below the crusher, the rotating assembly rotates below the crusher, and the rotating assembly passes through from the top to the bottom of the workbench, and is used to receive the solid-liquid coexistence of the oil palm fruit after being crushed by the crusher, the bottom of the rotating assembly is connected to the discharging mechanism, and the coexistence entering the rotating assembly is processed and then discharged through the discharging mechanism.

[0008] As a further solution of the present invention: wherein, the crusher includes a crushing box with a feed port, a crushing knife for crushing oil palm fruits is rotatably connected inside the crushing box, a screening plate is fixedly installed at the bottom of the crushing box, and a driving mechanism is fixedly installed at the upper end of the crushing knife.

[0009] As a further solution of the present invention: wherein, a support plate is fixedly installed on the upper end of the workbench, and the support plate is fixedly connected to the bottom of the crusher.

[0010] As a further solution of the present invention: wherein, the rotating assembly includes a rotating cylinder arranged below the crushing box, the rotating cylinder is rotatably connected to the workbench, and a through hole arranged along the wall of the rotating cylinder is opened below the rotating cylinder.

[0011] As a further solution of the present invention: wherein, an inverted conical material receiving port is arranged at the top of the rotating cylinder, an inverted material discharging port is also arranged at the bottom of the rotating cylinder, and a spiral storage plate is also arranged inside the rotating cylinder.

[0012] As a further solution of the present invention: wherein, a driven gear disc is fixedly installed on the outer side of the rotating cylinder, and a driving gear disc is rotatably connected to the upper end of the workbench. The driving gear disc is meshingly connected with the driven gear disc, and the rotation of the driving gear disc drives the driven gear disc to rotate.

[0013] As a further solution of the present invention: wherein, the discharge mechanism includes an oil outlet pipe connected to the rotating cylinder and a threaded cylinder designed to be connected to the discharge port, and the threaded cylinder is arranged inside the oil outlet pipe.

[0014] As a further solution of the present invention: wherein, the length of the threaded barrel is longer than the oil outlet pipe.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the centrifugal oil palm oil press of this embodiment, the liquid thrown out by the rotating drum when rotating can enter the oil outlet pipe, and the solids in the rotating drum will enter the threaded drum through the discharge port under the action of the spiral storage plate, thereby achieving solid-liquid separation. However, in order to ensure that there is no liquid inside the solids, an extrusion screw is provided inside the threaded drum, and a driving motor (not shown) is provided on the end face of the extrusion screw away from the discharge port. The extrusion screw is driven by the driving motor to rotate, which will cause the solids to circulate forward and be squeezed under the action of the extrusion screw. After extrusion, the solids will further discharge the liquid inside, and then flow from the threaded drum into the oil outlet pipe, thereby increasing the amount of oil collected. And the effect of solid-liquid separation can also be achieved.

[0017] 2. The centrifugal oil palm fruit press in this embodiment can rotate the coexisting objects from the crushing box by rotating the rotating drum. After the rotation, the coexisting objects will be thrown outward under the action of centrifugal force. Because the shape of the rotating drum is "cylindrical", after the rotation, the coexisting objects will stick to the inner wall of the drum. Because the inner wall of the drum is provided with through holes, the liquid will be thrown out of the rotating drum through the through holes, and the solid will continue to remain in the rotating drum. Thus, the effect of centrifugal oil extraction is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] See also Figure 1 , which is a schematic diagram of the overall structure in the present application, the device includes a workbench 10 for support, the workbench 10 includes a stirring mechanism arranged on the top and a discharging mechanism 20 arranged on the bottom, the stirring mechanism includes a crusher 30 and a rotating component 40 arranged below the crusher 30, the rotating component 40 rotates below the crusher 30, and the rotating component 40 runs from the top of the workbench 10 to the bottom, and is used to receive the solid-liquid coexistence of the oil palm fruit after the crusher 30, the bottom of the rotating component 40 is connected to the discharging mechanism 20, and the coexistence entering the rotating component 40 is processed and then discharged through the discharging mechanism 20.

[0026] Further, such as Figure 2 As shown, the crusher 30 includes a crushing box 31 with a feed inlet, a crushing knife 32 for crushing oil palm fruit is rotatably connected inside the crushing box 31, a screening plate 33 is fixedly installed at the bottom of the crushing box 31, and a driving mechanism is fixedly installed at the upper end of the crushing knife 32. In this embodiment, the driving mechanism can be a motor, and when the driving mechanism rotates, it drives the crushing knife 32 inside the crushing box 31 to rotate, and the oil palm fruit entering from the feed inlet is crushed, and the coexisting materials after crushing enter the next stage through the screening plate 33.

[0027] Furthermore, a support plate 50 is fixedly installed on the upper end of the workbench 10 , and the support plate 50 is fixedly connected to the bottom of the crusher 30 . Through the arrangement of the support plate 50 , the crusher 30 can be stably and fixedly installed on the table top of the workbench 10 .

[0028] like Figure 3 and Figure 4 As shown, the rotating assembly 40 includes a rotating cylinder 41 disposed below the crushing box 31, the rotating cylinder 41 is rotatably connected to the workbench 10, and a through hole 42 disposed along the cylinder wall of the rotating cylinder 41 is provided below the rotating cylinder 41. In this embodiment, the coexisting objects from the crushing box 31 can be rotated by rotating the rotating cylinder 41, and after the rotation, the coexisting objects will be thrown outward under the action of centrifugal force, because the shape of the rotating cylinder 41 is "cylindrical". After the rotation, the coexisting objects will stick to the inner wall of the cylinder, and because the inner wall of the cylinder is provided with a through hole 42, the liquid will be thrown out of the rotating cylinder 41 through the through hole, and the solid will continue to remain in the rotating cylinder 41. Thus, the effect of centrifugal oil extraction is achieved.

[0029] like Figure 5As shown, however, in the above process, the solids still exist in the rotating cylinder 41. If they are not cleaned, they will always exist in the rotating cylinder 41, resulting in more and more solids remaining in the rotating cylinder 41, affecting the subsequent centrifugal oil extraction process. Therefore, in order to solve this problem, the following improvements are made: an inverted conical receiving port 411 is set at the top of the rotating cylinder 41, and an inverted discharge port 412 is also set at the bottom of the rotating cylinder 41, and a spiral storage plate 413 is also set inside the rotating cylinder 41. In this embodiment, after the oil palm fruit coexistent enters the rotating cylinder 41, it will be thrown outwards inside the rotating cylinder 41 due to the centrifugal force, so as to separate the solid and liquid, and the liquid leaves the rotating cylinder 41, and the solid moves from top to bottom on the spiral storage plate 413, moves to the discharge port 412 and enters the discharge mechanism 20. Thus, the effect of centrifugal separation is achieved.

[0030] Furthermore, a driven gear disc 414 is fixedly installed on the outer side of the rotating cylinder 41, and a driving gear disc 415 is rotatably connected to the upper end of the workbench 10. The driving gear disc 415 is meshingly connected with the driven gear disc 414, and the rotation of the driving gear disc 415 drives the driven gear disc 414 to rotate, thereby realizing the rotation of the rotating cylinder 41.

[0031] like Figure 5 As shown, the discharge mechanism 20 includes an oil outlet pipe 21 connected to the rotating cylinder 41 and a threaded cylinder 22 designed to be connected to the discharge port 412, and the threaded cylinder 22 is arranged inside the oil outlet pipe 21. In this embodiment, the liquid thrown out by the rotating cylinder 41 when rotating can enter the oil outlet pipe 21, and the solid matter in the rotating cylinder 41 will enter the threaded cylinder 22 through the discharge port 412 under the action of the spiral placement plate 413, thereby achieving solid-liquid separation. However, in order to ensure that there is no liquid inside the solid matter, an extrusion screw 23 is arranged inside the threaded cylinder 22, and a driving motor (not shown in the figure) is arranged on the end face of the extrusion screw 23 away from the discharge port 412. The extrusion screw 23 is driven by the driving motor to rotate, which will cause the solid matter to circulate and move forward and be extruded under the action of the extrusion screw 23. The solid matter after extrusion will further discharge the liquid inside, and then flow from the threaded cylinder 22 into the oil outlet pipe 21, thereby increasing the amount of oil collected.

[0032] Furthermore, the length of the threaded barrel 22 is longer than the oil outlet pipe 21. This design can better collect the oil generated when the solids are squeezed inside the threaded barrel 22, and the solid debris after squeezing is easier to discharge, achieving the effect of facilitating the separate collection of the two.

[0033] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
