Description

Technical Field

[0001] This utility model relates to the field of peanut oil production technology, specifically to an extraction device for edible peanut oil. Background Technology

[0002] Peanut oil is a vegetable oil extracted from peanut seeds. It has a clear, light yellow to brownish-yellow color and a rich, characteristic peanut aroma. It is rich in unsaturated fatty acids, especially oleic acid and linoleic acid, and also contains vitamin E, sterols, and other nutrients. It offers health benefits such as lowering cholesterol and preventing cardiovascular disease.

[0003] In existing oil pressing equipment, the material is first put into the pressing chamber, and then the hydraulic device drives the pressure plate to squeeze the material, so that the oil contained in the material is squeezed out. Then the residue inside the pressing chamber is removed, and the material is put back in for the next pressing. Since the removal of residue and the addition of material take a certain amount of time, the interval between two consecutive pressings is long, which reduces the production efficiency. In addition, the frequent removal of residue and addition of material by workers results in high labor intensity. Utility Model Content

[0004] The purpose of this invention is to provide an edible peanut oil extraction device that effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A peanut oil extraction device includes a base. A servo motor is mounted at the center of the upper surface of the base. The output shaft of the servo motor is connected to a connecting shaft. Four cantilever arms are mounted at equal angles to the outer surface of the connecting shaft. Oil pressing cylinders are mounted at the ends of the cantilever arms, and the bottom of the oil pressing cylinders is in contact with the upper surface of the base. Oil grooves are formed on the surface of the oil pressing cylinders. A U-shaped frame is mounted on the upper surface of the base. An oil pressing mechanism adapted to the oil pressing cylinders is provided on one side of the U-shaped frame. A slag outlet is formed on the surface of the base, and a slag pushing mechanism adapted to the slag outlet is provided on the other side of the U-shaped frame. A feeding mechanism is provided on the upper surface of the base. The oil pressing mechanism, slag pushing mechanism, and feeding mechanism can simultaneously correspond one-to-one with the three oil pressing cylinders.

[0007] As can be seen, by using a servo motor to drive the four oil pressing cylinders to rotate sequentially below the oil pressing mechanism, the slag pushing mechanism, and the feeding mechanism, the oil pressing mechanism, the slag pushing mechanism, and the feeding mechanism can be carried out simultaneously. This avoids the interval between two adjacent oil pressing operations, improves the continuity of oil pressing, and thus increases production efficiency. Furthermore, the slag removal and feeding can be carried out automatically without manual operation, which greatly reduces the labor intensity of workers.

[0008] Furthermore, the oil pressing mechanism includes a first hydraulic cylinder mounted on the upper surface of the U-shaped frame, and a pressure plate is installed at the end of the telescopic end of the first hydraulic cylinder, the diameter of which is adapted to the inner diameter of the oil pressing cylinder.

[0009] Furthermore, the slag pushing mechanism includes a second hydraulic cylinder mounted on the upper surface of the U-shaped frame. A push plate is installed at the end of the telescopic end of the second hydraulic cylinder, and the push plate is coaxially distributed with the slag outlet.

[0010] Furthermore, the feeding mechanism includes a hopper mounted on the upper surface of the base via a support frame, with a screw conveyor installed at the bottom of the hopper, the discharge end of which can be located directly above one of the oil pressing cylinders.

[0011] Furthermore, an annular oil groove is provided on the surface of the base, and a first oil guide plate communicating with the annular oil groove is installed on the outer surface of the base.

[0012] Furthermore, an oil-receiving skirt is installed on the outer surface of the oil pressing cylinder, and a second oil guide plate is installed on the outer surface of the oil-receiving skirt, with the end of the second oil guide plate extending into the annular oil groove.

[0013] Furthermore, a suspension plate is installed on the top of the silo, and a stirring motor is installed on the upper surface of the suspension plate. The output shaft of the stirring motor is connected to a stirring shaft.

[0014] Furthermore, a protective cover is installed on the upper surface of the base, the servo motor is installed inside the protective cover, and the connecting shaft is rotatably connected to the protective cover through bearings.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model uses a servo motor to drive four oil pressing cylinders to rotate sequentially below the oil pressing mechanism, the slag pushing mechanism, and the feeding mechanism. This allows the oil pressing mechanism to press oil, the slag pushing mechanism to remove slag, and the feeding mechanism to feed slag simultaneously. After pressing oil, the oil pressing cylinder that has finished feeding can be immediately rotated below the oil pressing mechanism to continue pressing oil, thus avoiding the interval between two adjacent pressing operations, improving the continuity of oil pressing, and thus increasing production efficiency. Furthermore, the removal of slag and the feeding of slag can be carried out automatically without manual operation, greatly reducing the labor intensity of workers.

[0017] 2. This utility model uses a stirring motor to drive the stirring shaft to rotate, thereby stirring the material in the hopper. This allows the material to smoothly enter the screw conveyor, avoiding material sloshing that could prevent normal feeding and ensuring stable production operation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a peanut oil extraction device, including a base 1. A servo motor 101 is installed at the center of the upper surface of the base 1. The output shaft of the servo motor 101 is connected to a connecting shaft 102. Four cantilever arms 103 are installed coaxially and at equal angles on the outer surface of the connecting shaft 102. Oil pressing cylinders 104 are installed at the ends of the cantilever arms 103, and the bottom of the oil pressing cylinders 104 is in contact with the upper surface of the base 1. An oil outlet groove 105 is opened on the surface of the oil pressing cylinders 104. A U-shaped frame 106 is installed on the upper surface of the base 1. An oil pressing mechanism 2 adapted to the oil pressing cylinders 104 is provided on one side of the U-shaped frame 106. A slag outlet 107 is opened on the surface of the base 1, and a slag pushing mechanism 3 adapted to the slag outlet 107 is provided on the other side of the U-shaped frame 106. A feeding mechanism 4 is provided on the upper surface of the base 1. The oil pressing mechanism 2, the slag pushing mechanism 3, and the feeding mechanism 4 can simultaneously correspond one-to-one with the three oil pressing cylinders 104.

[0022] In operation, the connecting shaft 102 is driven by the servo motor 101 to rotate intermittently, with each rotation angle being 90 degrees. The oil pressing cylinder 104 is a vertically continuous cylindrical structure that slides on the surface of the base 1 under the drive of the servo motor 101. When the oil pressing cylinder 104 rotates to the position of the feeding mechanism 4, the feeding mechanism 4 automatically adds material into it. Then, the servo motor 101 drives the connecting shaft 102 to rotate 90 degrees, thereby causing the oil pressing cylinder 104 containing material to slide directly below the oil pressing mechanism 2. Pressure can then be applied to it by the oil pressing mechanism 2 to achieve the purpose of oil pressing. After oil pressing is completed, the servo motor 101 continues to drive the oil pressing cylinder 104 to slide until it slides directly above the slag outlet 107. Then, under the action of the slag pushing mechanism 3, the slag can be pushed out of the oil pressing cylinder 104 and fall from the slag outlet 107, completing the automatic slag removal. Afterward, the servo motor 101 drives the oil pressing cylinder 104 back to the feeding mechanism 4 to prepare for the next oil pressing.

[0023] Since the oil pressing mechanism 2, the slag removal mechanism 3, and the feeding mechanism 4 can all be carried out simultaneously, the oil pressing cylinder 104, after the oil pressing is completed, can be immediately rotated to the bottom of the oil pressing mechanism 2 to continue the oil pressing operation. This avoids the interval between two adjacent oil pressing operations, improves the continuity of oil pressing, and thus improves production efficiency. In addition, the slag removal and feeding can be carried out automatically without manual operation, which greatly reduces the labor intensity of workers.

[0024] All mechanisms in the device are uniformly controlled by a PLC controller to achieve automated production. A conveyor belt can be installed below the slag outlet 107 to transport the removed slag outwards, further reducing the physical labor of workers handling the slag.

[0025] Preferably, the oil pressing mechanism 2 includes a first hydraulic cylinder 201 mounted on the upper surface of the U-shaped frame 106, and a pressure plate 202 is mounted on the end of the telescopic end of the first hydraulic cylinder 201. The diameter of the pressure plate 202 is adapted to the inner diameter of the oil pressing cylinder 104.

[0026] When the oil pressing cylinder 104 carries the material and slides to directly below the pressure plate 202, the first hydraulic cylinder 201 is activated. Its telescopic end drives the pressure plate 202 to descend and extend into the oil pressing cylinder 104, thereby applying pressure to the material, squeezing the oil out of the material, and discharging it outward through the oil outlet 105.

[0027] Preferably, the slag pushing mechanism 3 includes a second hydraulic cylinder 301 mounted on the upper surface of the U-shaped frame 106. A push plate 302 is mounted on the end of the telescopic end of the second hydraulic cylinder 301. The push plate 302 is coaxially distributed with the slag outlet 107.

[0028] When the oil pressing cylinder 104 carrying the residue slides to directly above the residue outlet 107, the second hydraulic cylinder 301 is activated, and its telescopic end drives the push plate 302 to extend into the interior of the oil pressing cylinder 104, thus pushing the residue inside downward and pushing it out from the residue outlet 107.

[0029] It is worth noting that the inner diameter of the slag outlet 107 is larger than the inner diameter of the oil pressing cylinder 104, which can prevent the slag from getting stuck in the slag outlet 107.

[0030] Preferably, the feeding mechanism 4 includes a hopper 402 mounted on the upper surface of the base 1 via a support frame 401, and a screw conveyor 403 is mounted at the bottom of the hopper 402. The discharge end of the screw conveyor 403 can be located directly above one of the oil pressing cylinders 104.

[0031] When the oil pressing cylinder 104 slides directly above the discharge port of the screw conveyor 403, the screw conveyor 403 starts, and the material in the hopper 402 falls into the screw conveyor 403 under the action of gravity. The screw conveyor 403 can push the material into the oil pressing cylinder 104 by the screw, thus achieving the purpose of feeding.

[0032] The outer surface of the hopper 402 is equipped with a transparent observation window, which allows for timely replenishment when the material level is low.

[0033] Preferably, an annular oil groove 5 is formed on the surface of the base 1, and a first oil guide plate 501 communicating with the annular oil groove 5 is installed on the outer surface of the base 1.

[0034] The extracted peanut oil falls into the annular oil tank 5, and then flows into the collection bucket through the first oil guide plate 501.

[0035] Preferably, an oil-receiving skirt 6 is installed on the outer surface of the oil pressing cylinder 104, and a second oil guide plate 601 is installed on the outer surface of the oil-receiving skirt 6, with the end of the second oil guide plate 601 extending into the annular oil groove 5.

[0036] After the peanut oil is squeezed out from the oil outlet 105, it falls into the oil receiving skirt 6 and then into the annular oil trough 5 through the second oil guide plate 601. This prevents the peanut oil from falling onto the surface of the base 1 and becoming contaminated during the sliding process of the oil pressing cylinder 104.

[0037] Preferably, a suspension plate 7 is installed on the top of the hopper 402, and a stirring motor 701 is installed on the upper surface of the suspension plate 7. The output shaft of the stirring motor 701 is connected to a stirring shaft 702.

[0038] The stirring motor 701 drives the stirring shaft 702 to rotate, which stirs the material in the hopper 402, so that the material can smoothly enter the screw conveyor 403, avoiding the situation where the material cannot be fed normally due to sloshing, and ensuring the stable operation of production.

[0039] Preferably, a protective cover 8 is installed on the upper surface of the base 1, the servo motor 101 is installed inside the protective cover 8, and the connecting shaft 102 is rotatably connected to the protective cover 8 through a bearing.

[0040] The protective cover 8 provides protection for the servo motor 101 and also provides rotational support for the connecting shaft 102, so that the servo motor 101 is not subjected to vertical forces, thus improving its service life.
