Technical Field
[0001] This utility model belongs to the field of screw oil presses, specifically relating to a high-efficiency, fast-discharge screw oil press. Background Technology
[0002] In the edible oil processing industry, the performance and efficiency of oil presses are crucial for improving oil yield and quality. Traditional oil presses suffer from numerous problems that urgently need to be addressed during operation, limiting the efficiency and profitability of oil production.
[0003] However, oilseed crops (such as rapeseed and peanuts) are prone to clumping due to humidity or temperature during feeding. Directly feeding them into the pressing cylinder can lead to uneven load on the screw shaft, reduced extrusion efficiency, and even motor overload. Some equipment has attempted to add a stirring device, but lacks a directional dispersion structure for clump materials, resulting in poor pretreatment effects.
[0004] Moreover, during long-term pressing, oil residue particles are easily embedded in the inner wall of traditional strip filter holes, especially for high-fiber materials (such as tea seeds), which seriously affects the efficiency of continuous operation. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art, such as the tendency of oil crops to condense into lumps due to temperature and humidity during feeding, resulting in uneven load on the screw shaft and reduced extrusion efficiency, and the tendency of traditional strip filter holes to be embedded with oil residue, especially high-fiber materials, affecting the efficiency of continuous operation. Thus, a high-efficiency, fast-discharge screw oil press is realized.
[0006] To achieve the above-mentioned objectives, the technical solution of this utility model is: a high-efficiency, fast-discharge spiral oil press, comprising a working box, wherein a pressing cylinder is fixed on the top of the working box; The feed hopper is detachably connected to one side of the top of the pressing cylinder; The oil outlet hopper is connected to one side of the bottom of the pressing cylinder, and the inner wall of the oil outlet hopper is provided with an anti-clogging mechanism. One end of the pressing cylinder is fixed with the limiting slide cylinder, and a baffle is slidably connected inside the limiting slide cylinder.
[0007] In the above-mentioned high-efficiency, fast-discharge screw oil press, a rotating rod is rotatably connected inside the feed hopper, and several stripping rods are fixed on the outer surface of the rotating rod.
[0008] In the above-mentioned high-efficiency, fast-discharge spiral oil press, the two ends of the rotating rod are rotatably connected to the two sides of the feeding hopper, and a first drive motor is fixed on one side wall of the feeding hopper. The output end of the first drive motor is fixed to one end of the rotating rod.
[0009] In the above-mentioned high-efficiency, fast-discharge screw oil press, a screw shaft is coaxially arranged inside the pressing cylinder, and the diameter of the screw shaft has a gradually expanding structure along the material propulsion direction.
[0010] In the above-mentioned high-efficiency, fast-discharge screw oil press, a second drive motor is fixed on the outer side of the end of the pressing cylinder away from the feed hopper, and the output end of the second drive motor is fixedly connected to the end of the screw shaft through a coupling.
[0011] In the above-mentioned high-efficiency, fast-discharge spiral oil press, the bottom of the pressing cylinder is hinged to a rotating plate by a pin, and multiple strip-shaped filter holes are evenly distributed on the rotating plate.
[0012] In the aforementioned high-efficiency, fast-discharge screw oil press, the anti-clogging mechanism includes: Several strip-shaped inserts are horizontally inserted into the inner wall of the oil outlet bucket, and the insertion direction of the strip-shaped inserts is perpendicular to the rotation plane of the rotating plate. A filter plate is slidably disposed in the groove on the side wall of the oil outlet bucket. The filter plate is located downstream of the strip-shaped insert plate. The edge of the filter plate is provided with a second sealing rubber strip that cooperates with the groove of the oil outlet bucket. And a cover plate hinged to the opening end of the oil outlet bucket, wherein the inner edge of the cover plate is provided with a first sealing rubber strip.
[0013] In the aforementioned high-efficiency, fast-discharge spiral oil press, the strip-shaped insert is in the shape of a right triangle, and its hypotenuse has a continuously curved profile.
[0014] In the above-mentioned high-efficiency, fast-discharge spiral oil press, a sliding rod is slidably connected inside the limiting slide cylinder. One end of the sliding rod is fixedly connected to the baffle. A return spring is sleeved on the outer periphery of the sliding rod. One end of the return spring abuts against the back pressure surface of the baffle, and the other end abuts against the inner wall of the limiting slide cylinder.
[0015] Compared with the prior art, the high-efficiency, fast-discharge screw oil press of this invention has at least the following beneficial effects: This utility model relates to a high-efficiency, fast-discharge screw oil press. Through a rotating rod and a dispersing rod structure within the feed hopper, it can directionally disperse oilseeds such as rapeseed and peanuts that have clumped together due to temperature and humidity. The dispersing rod is driven by a first drive motor to rotate, effectively breaking down lumpy materials into fine particles, reducing the risk of uneven load on the screw shaft caused by direct entry into the pressing cylinder.
[0016] By utilizing the synergistic effect of the rotating plate and the strip-shaped insert plate, the oil residue embedded in the strip-shaped filter holes is automatically scraped off through the opening and closing action of the rotating plate during equipment operation, and secondary filtration is achieved in conjunction with the detachable filter plate; Based on the elastic baffle consisting of the limiting slide, sliding rod and return spring, the pressing back pressure can be adjusted in real time according to the material accumulation, which can reduce the residual oil rate while avoiding material blockage.

[0019] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed account of the efficient and rapid discharge screw oil press of this invention.
[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] This embodiment discloses a high-efficiency, fast-discharge screw oil press. Oilseed crops are prone to condensation and clumping due to temperature and humidity during feeding, leading to uneven load on the screw shaft and reduced pressing efficiency. Furthermore, traditional strip-shaped filter holes are susceptible to the embedding of oil residue, especially high-fiber materials, affecting continuous operation efficiency. Referring to… Figure 1-6It mainly includes a working box 1, a pressing cylinder 2 and a feeding hopper 3 fixed on the top of the working box 1, a feeding hopper 3 detachably connected to one side of the top of the pressing cylinder 2, an oil outlet hopper 8 connected to one side of the bottom of the pressing cylinder 2, an anti-blocking mechanism 10 provided on the inner wall of the oil outlet hopper 8, a limiting slide cylinder 9 fixed to one end of the pressing cylinder 2, and a baffle 14 slidably connected inside the limiting slide cylinder 9.
[0022] An inclined feed hopper 3 is detachably connected to the top side wall of the pressing cylinder 2 via a flange assembly. The outlet end of the feed hopper 3 forms a continuous material channel with the inner cavity of the pressing cylinder. A conical oil outlet hopper 8 is provided through the bottom side wall of the pressing cylinder 2. The inner wall of the oil outlet hopper 8 is integrated with an anti-clogging mechanism 10 consisting of an anti-clogging filter assembly. A limiting slide cylinder 9 is coaxially fixed at the material output end of the pressing cylinder 2. An axially displaceable baffle 14 is slidably fitted inside the limiting slide cylinder 9. The working surface of the baffle 14 forms a dynamic sealing fit with the inner wall of the pressing cylinder, and its displacement path is coaxially corresponding to the material propulsion direction.
[0023] Reference Figure 1-4 A rotating rod 5 is rotatably connected inside the feed hopper 3, and several stripping rods 6 are fixed on the outer surface of the rotating rod 5. The two ends of the rotating rod 5 are rotatably connected to the two sides of the feed hopper 3, and a first drive motor 4 is fixed on one side wall of the feed hopper 3. The output end of the first drive motor 4 is fixed to one end of the rotating rod 5.
[0024] A screw shaft 11 is coaxially arranged inside the pressing cylinder 2, and the diameter of the screw shaft 11 gradually expands along the material feeding direction. A second drive motor 7 is fixed on the outer side of the end of the pressing cylinder 2 away from the feed hopper, and the output end of the second drive motor 7 is fixedly connected to the end of the screw shaft 11 through a coupling.
[0025] The rotating rod 5, which is coaxially arranged inside the feed hopper 3, is dynamically sealed to the side wall of the feed hopper through rolling bearings at both ends. The surface of the rotating rod 5 is evenly distributed with stripping rods 6, which are driven to rotate by the first drive motor 4 through the coupling, effectively breaking up agglomerated materials and guiding the loose materials to fall evenly into the pressing chamber.
[0026] The screw shaft 11, coaxially assembled inside the pressing cylinder 2, adopts a variable diameter, gradually expanding structure design. Its surface spiral lead decreases along the material propulsion direction, forming a continuously shrinking compression space with the inner wall of the pressing cylinder. The end of the screw shaft 11 is rigidly connected to the output end of the second drive motor 7 via a spline coupling. Combined with the wear-resistant groove structure on the inner wall of the pressing cylinder, this creates a combined force field of spiral propulsion and radial extrusion. Auxiliary guide ridges are added to the surface of the screw shaft 11 to enhance the frictional heating effect by altering the material's movement trajectory, thus promoting oil separation.
[0027] Reference Figure 1-6The bottom of the pressing cylinder 2 is hinged to a rotating plate 17 via a pin. Multiple strip-shaped filter holes 15 are evenly distributed on the rotating plate 17. The anti-clogging mechanism 10 includes: several strip-shaped inserts 1001 horizontally inserted into the inner wall of the oil outlet 8, the insertion direction of the strip-shaped inserts 1001 being perpendicular to the rotation plane of the rotating plate 17; a filter plate 1002 slidably disposed in a groove on the side wall of the oil outlet 8, the filter plate 1002 being located downstream of the strip-shaped inserts 1001; and a second sealing rubber strip on the edge of the filter plate 1002 that mates with the groove of the oil outlet 8. A cover plate 1003 is hinged to the opening end of the oil outlet 8, and a first sealing rubber strip is provided on the inner edge of the cover plate 1003. The strip-shaped inserts 1001 are right-angled triangles with continuously curved hypotenuses.
[0028] The rotating plate 17 forms a variable-angle hinge mechanism with the bottom of the pressing cylinder 2 via a pin. The profile of the strip filter hole 15 adopts a gradually narrowing streamline design, and when the rotating plate is closed, it forms an annular sealing band with the inner wall of the pressing cylinder.
[0029] The strip-shaped insert plate 1001 adopts a right-angled triangular three-dimensional structure, with its hypotenuse designed as a continuous wavy surface, forming a staggered meshing relationship with the strip-shaped filter holes 15. This allows for multi-dimensional scraping of the inner wall of the filter holes during the opening and closing of the rotating plate, making it particularly suitable for removing blockages from high-fiber materials such as tea seeds. The filter plate 1002 is slidably assembled in the dovetail guide groove on the side wall of the oil outlet hopper 8, and adopts a double-layer stepped filter screen structure, with the mesh size decreasing gradually along the oil flow direction. The second sealing rubber strip adopts an embedded labyrinth seal design to ensure the airtightness of the filter plate under vibration conditions; The cover plate 1003 is opened and closed quickly through a hinge mechanism, and the first sealing rubber strip adopts a composite lip seal structure.
[0030] Reference Figure 1-4 A sliding rod 12 is slidably connected inside the limiting slide cylinder 9. One end of the sliding rod 12 is fixedly connected to the baffle 14. A return spring 13 is sleeved on the outer periphery of the sliding rod 12. One end of the return spring 13 abuts against the back pressure surface of the baffle 14, and the other end abuts against the inner wall of the limiting slide cylinder 9.
[0031] The axis of the sliding rod 12 is parallel to the advancing direction of the screw shaft 11. The end of the sliding rod 12 is rigidly connected to the baffle 14 through a flange, and the two form a linkage with synchronous axial displacement, ensuring that the working surface of the baffle is always perpendicular to the material advancing direction.
[0032] The return spring 13 adopts a pre-tightened assembly structure, with its two ends abutting against the annular boss of the baffle 14 and the stepped inner wall of the limiting slide cylinder 9, respectively. When the material accumulation increases, the baffle 14 is squeezed, causing the sliding rod 12 to move backward and compress the spring. At this time, the spring stores energy and generates a reverse force. When the material amount decreases, the spring releases energy to push the baffle to return to its original position, achieving dynamic balance of back pressure.
[0033] During the reciprocating motion, the sliding rod 12 generates rotational friction with the inner wall of the limiting slide cylinder 9, effectively removing impurities adhering to the cylinder wall. It has both dynamic sealing and self-maintenance functions, significantly extending the continuous operation cycle of the equipment.
[0034] The working principle of this utility model of a high-efficiency, fast-discharge screw oil press is as follows: When using this device, firstly, the oilseed crops are placed into the feed hopper 3, and the first drive motor 4 is started. The coupling on the first drive motor 4 drives the rotating rod 5 and the dispersing rod 6 to rotate. The dispersing rod 6 disperses the oilseed crops that have clumped together. Then, the oilseed crops fall into the inside of the pressing cylinder 2. The second drive motor 7 is started, and the coupling on the second drive motor 7 drives the screw shaft 11 to rotate. The screw shaft 11 cooperates with the pressing cylinder 2 to squeeze the oilseed crops and push them to move. The squeezed oil flows out through the strip filter holes 15 to the oil outlet hopper 8 and then flows out through the filter plate 1002. When the oil crops move to the baffle 14, the return spring 13 applies pressure to the baffle 14 to better squeeze and extract oil from the oil crops. When the oil crops accumulate to a certain extent, the oil crops push the baffle 14 and the slide rod, causing the baffle 14 to push at one end of the pressing cylinder 2, and the slide rod to move on the limiting sleeve, so that the pressed oil crops are pushed out and discharged through the discharge hopper 16. When the oil crops accumulate to a small amount, the baffle 14 is reset by the pressure of the return spring 13.
[0035] Impurities tend to accumulate in the strip filter holes 15 after prolonged use. When cleaning the strip filter holes 15, open the cover plate 1003 and then use a tool to open the rotating plate 17 on the pressing cylinder 2, so that the rotating plate 17 rotates along one of its own axes. The strip filter holes 15 on the rotating plate 17 pass through the strip insert plate 1001, which can clean the filter holes. When the inside of the pressing cylinder 2 is blocked, the rotating plate 17 can also be opened to discharge the oil crops inside the pressing cylinder 2. Impurities fall onto the filter plate 1002. The filter plate 1002 can then be removed and the impurities on the filter plate 1002 cleaned.
