Description
Technical Field
[0001] This utility model relates to the field of woody oilseed pressing, and in particular to a low-temperature hydraulic pressing device for high-oil-content woody oilseeds without the need for cloth covering. Background Technology
[0002] High-oil-content woody oilseeds are rich in heat-sensitive nutrients such as unsaturated fatty acids and vitamins, making low-temperature pressing the mainstream choice for ensuring oil quality. Low-temperature pressing reduces oxidative damage to nutrients; however, compared to high-temperature pressing, the oilseeds have higher viscosity at low temperatures, and the adhesion between the oil residue and the oil is enhanced, directly leading to a significant increase in the difficulty of separating the oil from the residue.
[0003] Traditional cryogenic pressing equipment typically uses cloth wrapping of the raw material or cloth covering of the filter opening to filter oil residue. However, the cloth wrapping needs to be disassembled, cleaned, or replaced after each use, which not only increases manual operation steps and extends the production cycle but also incurs cloth wear and tear costs. Therefore, existing equipment sometimes uses a filtration mechanism instead of cloth wrapping to filter oil residue. However, existing filtration structures are mostly designed with a fixed filter screen and static oil collection. Due to the increased adhesion between oil residue and oil in the low-temperature environment, the oil residue easily adheres to each other, causing a large amount of oil residue to accumulate on the filter screen surface and clog the pores. Without a device to collect the oil residue, frequent shutdowns for cleaning are required, otherwise, the oil extraction efficiency will be reduced. Based on this, we designed a cloth-free cryogenic hydraulic pressing device for high-oil-content woody oilseeds to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a low-temperature hydraulic pressing device for high-oil-content woody oil crops without the need for wrapping, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature hydraulic pressing device for high-oil-content woody oil crops without covering, comprising a hydraulic unit and a filter unit, wherein the hydraulic unit includes a hydraulic plate and a pressing table, and the filter unit is disposed outside the hydraulic unit;
[0006] The filter unit includes an oil outlet, a filter screen, and a detachable collection pipe. The collection pipe is located below the oil outlet, and the filter screen passes through the oil outlet from above and extends downward into the collection pipe.
[0007] The woody plant is placed on the pressing table, and the oil is pressed by the hydraulic plate and flows out from the oil outlet. When the oil passes through the filter screen, the oil residue is blocked by the filter screen and falls to the bottom. When it is necessary to clean the filter screen or when the oil pressing is finished, simply lift the filter screen and the filter residue deposited at the bottom from the top of the oil outlet, and then collect the remaining oil in the collection pipe.
[0008] Preferably, a mounting plate is fixedly connected to the top of the filter screen, two slots are opened above the oil outlet, the mounting plate is snapped into the slots, a through hole is opened at the bottom of the oil outlet, and the filter screen passes through the through hole and extends downward into the collection pipe.
[0009] Preferably, both sides of the oil outlet and the collecting pipe are fixedly connected with arc-shaped threaded parts and auxiliary blocks, with the auxiliary blocks located inside the arc-shaped threaded parts.
[0010] Preferably, the outer wall of the arc-shaped threaded component is threaded with a threaded cap, and a boss is fixedly connected in the middle of the threaded cap. The ends of the boss and the auxiliary block that are close to each other are both set to be arc-shaped to help position the threaded cap to connect accurately with the arc-shaped threaded component.
[0011] Preferably, a base plate is fixedly connected to the bottom of the pressing table, and four support columns are fixedly connected to the upper surface of the base plate. The four support columns are located at the four corners of the upper surface of the base plate. A fixing block is fixedly connected to the top of the support column. A groove is opened on the surface of the fixing block. A hydraulic cylinder is fixedly connected to the inner wall of the groove. The output end of the hydraulic cylinder passes through the fixing block and extends downward. The top of the hydraulic plate is fixedly connected to the output end of the hydraulic cylinder.
[0012] Preferably, the pressing table has multiple oil guide ports arranged in a circumferential array above it, and an oil receiving groove is fixedly connected to the outer wall of the pressing table. The oil receiving groove is located below the oil guide ports, and a sleeve is fixedly connected to the top of the oil receiving groove. The sleeve is fitted onto the outer wall of the pressing table.
[0013] Preferably, the oil receiving groove has a sliding groove inside, a sliding plate is slidably connected to the inner wall of the sliding groove, an operating rod is fixedly connected to the outer wall of the sliding plate, and the sliding groove is located on both sides of the oil outlet.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. This utility model achieves a significant breakthrough in the sludge filtration process, completely eliminating the reliance on cloth wrapping in traditional devices. The structure design of the filter screen passing through the oil outlet and extending to the collection pipe can effectively block oil sludge and cause it to settle at the bottom of the filter screen, achieving complete separation of oil sludge and grease. This effectively avoids the oil sludge leakage problem caused by damage to the traditional cloth wrapping, ensuring the purity of the finished oil. At the same time, the filter screen is connected to the oil outlet slot by the mounting plate. After pressing, the filter screen can be directly lifted from the top along with the oil sludge at the bottom. The operation is convenient and there is no need to frequently stop the machine to clean the filter screen blockage, greatly reducing manual operation steps and time costs. It also avoids the problem of oil sludge adhering to the inner wall of the equipment and being difficult to clean, improving the oil sludge separation efficiency and hygiene safety.
[0016] 2. This utility model uses a sliding groove in the oil receiving tank to cooperate with a sliding plate. The sliding plate can be flexibly controlled by the operating rod to adjust the opening and closing of both sides of the oil outlet. This makes it convenient to close the sliding plate when replacing the collection pipe or cleaning the oil receiving tank, thus avoiding grease leakage and waste. The overall structure takes into account both the high efficiency of filtration and the controllability of oil output. It not only solves the core pain points of traditional devices, but also improves the convenience of operation and helps to improve the efficiency of large-scale production.
