Description

Technical Field

[0001] This utility model relates to the field of vegetable oil production technology, and in particular to an automatic separation device for vegetable oil pressing residue. Background Technology

[0002] Vegetable oils are fats extracted from plant seeds, fruits, or other parts, and their main component is triglycerides. They are usually liquid at room temperature, contain no cholesterol, and are rich in nutrients such as vitamin E and polyunsaturated fatty acids, which are beneficial to cardiovascular health. Common vegetable oils include soybean oil, rapeseed oil, peanut oil, corn oil, and olive oil, and are widely used in cooking, food processing, and biodiesel production.

[0003] In the process of vegetable oil production, the effective separation of oil residue is crucial. However, most existing oil residue separation devices adopt filtration, which easily leads to the accumulation of oil residue on the filter components, reducing the filtration speed and effect. At the same time, there is a lot of residual vegetable oil in the oil residue, which is not conducive to full separation and resource utilization. Utility Model Content

[0004] One objective of this invention is to provide an automatic separation device for vegetable oil pressing residue. This invention addresses the issue mentioned in the background that effective separation of residue is crucial in the vegetable oil production process. However, most existing residue separation devices use filtration, which easily leads to residue accumulation on the filter components, reducing filtration speed and effectiveness. At the same time, the residue contains a large amount of residual vegetable oil, which is not conducive to full separation and resource utilization.

[0005] An automatic separation device for vegetable oil pressing residue according to an embodiment of the present invention includes:

[0006] The separation component includes a housing, inside which a guide plate and a liquid storage tank are respectively arranged from top to bottom, a filter component inside the housing, and a pushing mechanism for pushing oil is installed inside the liquid storage tank;

[0007] The pressing mechanism is installed inside the housing of the separation component and is used to press vegetable oil. The pressing mechanism includes a pressing cylinder fixed inside the housing. A slag discharge port is opened at the lower end of one end of the pressing cylinder. Oil leakage holes are opened at the lower ends of the outer side of the pressing cylinder. A quantitative feeding component is installed at the top of the pressing cylinder. A second spiral blade shaft is rotatably arranged inside the pressing cylinder.

[0008] The slag discharge mechanism is installed inside the housing of the separation component to discharge oil slag. The slag discharge mechanism includes a conveying cylinder fixed inside the housing. The slag inlet of the conveying cylinder is located at the slag discharge port on the pressing cylinder. A third helical blade shaft is rotatably installed inside the conveying cylinder. The third helical blade shaft is fixedly installed at the output end of the second motor. A second oil leakage hole is opened at the bottom of the conveying cylinder. A slag discharge hose is fixedly installed at the slag discharge end of the conveying cylinder.

[0009] Preferably, a drain valve is fixedly installed on one end of the outer side of the box corresponding to the liquid storage compartment, and a control valve is fixedly installed on the outer side of the drain valve.

[0010] Preferably, the filter assembly includes a coarse filter and a fine filter that are respectively movable inside the guide plate. Both the coarse filter and the fine filter are fixedly disposed on one side of the sealing cover, and a handle is fixedly disposed on one side of the sealing cover.

[0011] Preferably, the quantitative feeding component includes a hopper fixed to the top of the pressing cylinder, a support plate fixedly provided on the top of the hopper, and a first spiral blade shaft rotatably provided inside the support plate. The first spiral blade shaft and the second spiral blade shaft are synchronized by a drive component.

[0012] Preferably, the drive assembly includes a bearing seat fixed to the top of the support plate and a first bevel gear fixed to the top of the first helical blade shaft. A second bevel gear is rotatably mounted on one side of the bearing seat via a rotating shaft. A transmission assembly is connected between the rotating shaft and the second helical blade shaft. The first helical blade shaft is fixedly mounted at the output end of the first motor.

[0016] The beneficial effects of this utility model are:

[0017] This invention effectively avoids the problems of oil residue accumulation and excessive vegetable oil residue by setting up a separation component, a pressing mechanism, and a slag discharge mechanism. In use, the raw material is received by the hopper of the quantitative feeding component. The first spiral blade shaft is driven by the drive component to quantitatively convey the material to the pressing cylinder. The second spiral blade shaft rotates synchronously to spirally compress the material. The vegetable oil flows into the box through the oil leakage hole of the pressing cylinder and is guided by the guide plate to the coarse filter screen and the fine filter screen to achieve two-stage filtration. After the oil flows into the storage tank, it is actively pushed out by the pusher plate of the pushing mechanism. The oil residue enters the conveying cylinder through the slag discharge port. During the process driven by the third spiral blade shaft, the residual oil is separated again through the second oil leakage hole. Finally, the dry residue is discharged through the slag discharge hose, thereby effectively improving the separation rate of oil residue and vegetable oil and avoiding the problems of oil residue accumulation and excessive vegetable oil residue.

[0018] This invention effectively avoids the problem of untimely discharge of vegetable oil from the storage tank by setting up a pushing mechanism. When the amount of vegetable oil in the storage tank reaches a certain level, the electric push rod drives the oil pushing plate to slide in the storage tank, pushing the vegetable oil towards the drain valve and control valve. By controlling the opening and closing of the drain valve, the vegetable oil in the storage tank can be discharged in time, avoiding the accumulation of vegetable oil in the storage tank, ensuring the timely discharge and collection of vegetable oil, and improving production efficiency and resource utilization.

[0029] The slag discharge mechanism 3 is installed inside the housing 101 of the separation component 1 to discharge oil slag.

[0032] Working principle: First, the raw material enters the pressing cylinder 208 through the quantitative feeding component. The hopper 201 feeds the raw material in. The first spiral blade shaft 203 in the support plate 202 and the second spiral blade shaft 210 in the pressing cylinder rotate synchronously under the action of the drive component to ensure uniform pressing of the raw material. The drive component transmits the power of the first motor 213 to the two spiral blade shafts through the meshing of the first bevel gear 204 and the second bevel gear 205, as well as the pulley and belt of the transmission component 212. During the pressing process, the vegetable oil flows out through the oil leakage hole at the lower end of the outer side of the pressing cylinder 208, while the oil residue is discharged through the slag discharge port 211. The discharged oil residue enters the conveyor belt. Driven by the third spiral blade shaft 303, the oil residue in cylinder 301 undergoes secondary separation through the second oil leakage hole 302. The final dry residue is discharged through the slag discharge hose 305. At the same time, the leaked vegetable oil is filtered through the coarse filter screen 106 and fine filter screen 107 in the guide plate 102. The filtered vegetable oil flows into the storage tank 103. When the vegetable oil in the storage tank reaches a certain amount, the electric push rod 401 in the pushing mechanism 4 drives the oil pushing plate 402 to slide, pushing the vegetable oil towards the drain valve and control valve 105. By controlling the opening and closing of the drain valve, the vegetable oil in the storage tank can be discharged in time, completing the entire automatic separation process of oil residue and vegetable oil.
