Description

Technical Field

[0001] The present invention discloses a double-roller crushing structure of an oil pressing and screening integrated machine and a peanut oil pressing and screening integrated machine, which relates to a double-roller crushing structure of a peanut oil pressing and screening integrated machine for crushing peanuts before oil pressing, and belongs to the technical field of peanut oil pressing processing, and particularly relates to a double-roller crushing structure of a peanut oil pressing and screening integrated machine for crushing peanuts by driving two rollers to rotate in opposite directions through a bidirectional lead screw, and adjusting the distance between the two rollers through a third electric push rod to adjust the degree of crushing of the peanuts. Background Art

[0002] Peanut oil press is a machine specially used to extract oil from peanuts. It can squeeze out the oil in the peanut raw material to obtain peanut oil for edible or industrial use. The existing peanut oil press usually puts the crushed peanut kernels into the hopper of the oil press. The peanut kernels are squeezed under the high pressure of the oil press, and the oil flows out and enters the collection container through a special channel. The squeezed oil is left to settle for a period of time so that the impurities naturally sink to the bottom. The upper clear oil after standing is poured into the filtering equipment, or the filter cloth and filter screen are used for the first filtration to remove larger particle impurities. The coarsely filtered oil is filtered again through a fine filter screen or filter paper. However, it has many disadvantages during use. First, before each oil pressing, it is necessary to manually pour an appropriate amount of peanuts into the device. When a large amount of peanuts need to be pressed for oil, it is necessary to manually load the peanuts multiple times, which is not only time-consuming and labor-intensive, but also easily leads to reduced efficiency. Secondly, the existing peanut oil press directly collects the oil, and it needs to stand for a period of time and then manually filter the peanut oil multiple times. This series of filtration steps not only increases the time cost of the operation, but also increases the labor intensity. In addition, there is a risk of cross-contamination during multiple manual operations.

[0003] Announcement No. CN104163002A discloses a peanut oil press, including a machine body, a feed inlet is provided on the top of the machine body, the lower end of the feed inlet is connected to an oil pressing roller, an oil outlet is correspondingly provided below the oil pressing roller, a filter membrane is provided below the oil outlet, a peanut skin removal mechanism is provided in the feed inlet, a grinding mechanism is provided below the peanut skin removal mechanism, the grinding mechanism includes mutually meshing gear shafts, a heating roller and a grinding wheel provided on the heating roller are provided in the oil pressing roller, the heating roller is fixed on a rotating shaft, and the rotating shaft is controlled by a hand wheel. The peanut oil press of the present invention removes peanut skins through a peanut skin removing mechanism, so that the generation of shell debris is reduced during the oil pressing process, and the peanut grains are ground into small peanut particles. A heating roller and a grinding wheel arranged on the heating roller are arranged in the oil pressing roller, which is conducive to oil discharge under high temperature conditions. A filter membrane is arranged below the oil outlet, and the oil product is cleaner. Announcement No. CN104163001A discloses a peanut oil press, including a machine body, a feed hopper is arranged on the top of the machine body, a feed pipe is connected to the lower end of the feed hopper, a steam nozzle is extended into the feed pipe, the lower end of the feed pipe is connected to a heating chamber, an electric heating wire is arranged in the heating chamber, a rear end of the heating chamber is connected to a stirring chamber, a stirring structure is arranged in the stirring chamber, an oil residue separation pipe is arranged at the outlet end of the stirring chamber, a plurality of heating rings are arranged in the oil residue separation pipe, the bottom of the oil residue separation pipe is connected to the oil outlet, and a granulating mechanism is arranged in the oil residue separation pipe. The peanut oil pressing and filtering machine needs to manually load the peanuts in a quantitative manner multiple times when pressing a large amount of peanuts, which is not only time-consuming and labor-intensive, but also easily leads to reduced efficiency. The peanut oil cannot be filtered automatically, and the oil needs to be collected and left to stand for a period of time, and the peanut oil needs to be filtered multiple times manually. This series of filtering steps not only increases the time cost of the operation, but also increases the labor intensity. In addition, there is a risk of cross-contamination during multiple manual operations.

[0004] In order to improve the above problems, the applicant filed a Chinese invention patent application entitled "A Peanut Oil Pressing, Screening and Filtering Machine", which finely crushes the peanuts through a crushing component, squeezes the peanuts through an oil pressing component, and then filters them multiple times. However, in the process of crushing peanuts in the above-mentioned peanut oil pressing, screening and filtering machine, the relatively small fragments may cause the oil to oxidize due to excessive exposure to the air, affecting the taste and nutritional value of the oil. The peanuts crushed by the blades may produce more fine particles, which are easily absorbed by the oil during the oil pressing process, affecting the purity of the oil. In addition, the blade crushing requires high energy consumption to drive the high-speed rotation of the blade. The blade crushing equipment may require more frequent maintenance and replacement of blades, increasing production costs. Summary of the invention

DETAILED DESCRIPTION Example 1

[0013] The present invention discloses a double-roller crushing structure of an integrated oil pressing and filtering machine, comprising a double-roller crushing shell (39), a bottom plate (33), a push plate (41), a support column (43), a third electric push rod (40), a first rotating roller (44), a second rotating roller (42), a rotating disk (38), a rotating spacer column (37), an L-shaped fixing block (34), a third motor (36) and a bidirectional screw rod (35). The top surface of the double-roller crushing shell (39) is fixedly connected to the bottom surface of the material storage box (2), and the bottom end of the double-roller crushing shell (39) is fixedly connected to the outer side surface of the top end of the material storage box (6). Preferably, the double-roller crushing shell (39) is in a rectangular parallelepiped structure. The length and width of the double-roller crushing shell (39) remain unchanged from the top to three-quarters, and gradually decrease from three-quarters to seven-eighths. The length and width remain unchanged from seven-eighths to the bottom. The double-roller crushing shell (39) is in a hollow structure. The bottom ends of the two planes of the double-roller crushing shell (39) near the bottom and perpendicular to the central axis of the blanking box (6) are in an arc-shaped structure, and the arc fits the side of the blanking box (6). The storage box (2) is connected to the blanking box (6) through the double-roller crushing shell (39). The bottom plate (33) is placed inside the double-roller crushing shell (39). The bottom plate (33) is in a square frame structure. The outer side surface of the bottom plate (33) is fixedly connected to the inner side surface of the double-roller crushing shell (39) at three quarters. A slide rail is disposed on the top surfaces of two opposite sides of the bottom plate (33). The push plate (41) is slidably connected to the bottom plate (33) via a slide rail on the bottom plate (33), and the push plate (41) is in a square plate-like structure. A supporting column (43) is fixedly mounted on the top surfaces of both ends of the push plate (41), and the two supporting columns (43) are slidably connected to the inner side surface of the double-roller crushing shell (39). One end of the third electric push rod (40) is fixedly connected to the inner side of the double-roller crushing shell (39), and the other end is fixedly connected to the push plate (41). One axle of the first rotating roller (44) is rotatably connected to the side of the double-roller crushing shell (39); another axle of the first rotating roller (44) passes through the other side of the double-roller crushing shell (39), and a supporting bearing is disposed between the side. The double-roller crushing shell (39) has a notch on the side. One axle of the second rotating roller (42) is rotatably connected to a supporting column (43), the other axle of the second rotating roller (42) passes through the supporting column (43) and the side notch of the double-roller crushing shell (39), and a supporting bearing is disposed between the second rotating roller and the supporting column (43). The central axes of the first rotating roller (44) and the second rotating roller (42) are on the same plane and have the same diameter. The rotating disk (38) is in a disc-shaped structure. Two rotating disks (38) are provided. One rotating disk (38) is fixedly connected to the other axle of the first rotating roller (44) and is coaxially arranged with the first rotating roller (44). The other rotating disk (38) is fixedly connected to the other axle of the second rotating roller (42) and is coaxially arranged with the second rotating roller (42). The rotating spacer columns (37) are fixedly placed on the plane of the rotating disk (38) and are placed close to the side of the rotating disk (38). The rotating disk (38) is provided with two groups. One group of rotating spacer columns (37) corresponds to one rotating disk (38). The rotating spacer columns (37) in each group are arranged equidistantly along the circumference of the rotating disk (38). The rotating disk (38) is placed between the rotating spacer column (37) and the double roller crushing shell (39). The L-shaped fixing block (34) is fixedly connected to the side of the double-roller crushing shell (39), and the two L-shaped fixing blocks (34) are on the same plane and have openings facing each other. The third motor (36) is fixedly placed on an L-shaped fixing block (34). One end of the bidirectional screw rod (35) passes through the L-shaped fixing block (34) and is fixedly connected to the motor shaft of the third motor (36), and a support bearing is arranged between the bidirectional screw rod (35) and the L-shaped fixing block (34). The other end of the bidirectional screw rod (35) is rotatably connected to another L-shaped fixing block (34). The bidirectional screw rod (35) is meshed with the rotating disk (38) through a rotating spacer column (37). The bidirectional threads of the bidirectional screw rod (35) correspond to the two rotating disks (38) one by one. When in use, the third electric push rod (40) drives the push plate (41) and the second roller (42) above to slide, and adjusts the distance between the second roller (42) and the first roller (44), thereby accurately controlling the degree of crushing of the peanut particles. As the peanuts enter the double-roller crushing shell (39) from the storage box (2), the start of the third motor (36) drives the bidirectional screw rod (35) to rotate, thereby causing the second roller (42) and the first roller (44) to rotate in opposite directions. This opposite rotation can effectively crush the peanuts, and the crushed peanut fragments will eventually fall into the drop box (6), preparing for the subsequent oil pressing process. Example 2

[0014] The difference between this embodiment and embodiment 1 is that: a plurality of extruded particles (45) are evenly distributed on the side of the second rotating roller (42), and a plurality of extruded particles (45) are evenly distributed on the side of the first rotating roller (44), and the extruded particles (45) are in a hemispherical structure. When in use, the extruded particles (45) can prevent the peanut pieces from adhering to the surfaces of the first rotating roller (44) and the second rotating roller (42); The bidirectional screw rod (35) is meshed with the rotating disc (38) via a rotating spacer column (37); the bidirectional threads of the bidirectional screw rod (35) correspond to the two rotating discs (38) one by one; one of the rotating discs (38) is fixedly connected to the other wheel shaft of the first rotating roller (44); and the other rotating disc (38) is fixedly connected to the other wheel shaft of the second rotating roller (42). This design enables the first rotating roller (44) and the second rotating roller (42) to rotate in opposite directions, thereby efficiently crushing the peanuts, improving the crushing efficiency, and ensuring the synchronous rotation of the two rotating rollers, thereby maintaining the continuity and stability of the crushing process; The push plate (41) is slidably connected to the bottom plate (33) via a slide rail on the bottom plate (33); a support column (43) is fixedly disposed on the top surfaces of both ends of the push plate (41); an axle of the second roller (42) is rotatably connected to a support column (43); another axle of the second roller (42) passes through a notch in the side of the support column (43) and the double-roller crushing shell (39); and a support bearing is disposed between the second roller (42) and the support column (43). The position of the push plate (41) and the second roller (42) above the push plate (41) can be precisely adjusted through the action of a third electric push rod (40), thereby changing the distance between the second roller (42) and the first roller (44), so that the device can flexibly adjust the crushing degree according to the size and hardness of the peanuts, and is suitable for peanuts of different varieties; The design of the double-roller crushing shell (39) gradually decreasing in length and width from three-quarters to seven-eighths can effectively reduce the accumulation and clogging of crushed peanuts on the inner wall of the double-roller crushing shell (39).

Example 3

[0017] The difference between this embodiment and the first embodiment is that a connecting block (31) is fixedly disposed at the other end of the blade of the blade assembly (24), and a scraper (32) is fixedly connected to the connecting block (31).

Regular and effective cleaning can reduce the accumulation of impurities inside the equipment, help prevent corrosion and wear, and thus extend the service life of the equipment. At the same time, it can also reduce the risk of microbial growth and contamination caused by the accumulation of residues, thereby ensuring the hygiene and safety of the product. A rubber strip is fixedly disposed on the side of the extrusion plate (26). The design that the diameter of the extrusion plate (26) is slightly smaller than the diameter of the inner side of the blanking box (6) can enhance the sealing performance between the extrusion plate (26) and the inner side of the blanking box (6), thereby preventing the side leakage of peanut crushed materials during the extrusion process, ensuring that all materials can be effectively squeezed, and improving the extraction rate of oil. The blade assembly (24) is composed of a rotating shaft and a plurality of blades, wherein the width and thickness of the blades gradually decrease from one end connected to the rotating shaft to the other end, and the plurality of blades are arranged equidistantly along the circumference of the rotating shaft, which is conducive to uniform crushing of the peanuts, improves the crushing efficiency, and makes it easier to release the oil from the cells. In the subsequent oil pressing process, the oil in the peanuts can be more completely extracted, thereby improving the oil yield. At the same time, the crushed peanut fragments are easier to be pressed and processed, reducing the working difficulty of the oil press, thereby improving the overall oil pressing speed; The outer side surface of the inner layer (22) of the pulverizer is at a certain distance from the inner side surface of the outer shell (4) of the pulverizer.

The sufficient crushing can destroy the structure of the peanut cells, making it easier for the oil to be released from the cells, thereby improving the oil yield. One end of the screw pusher (25) passes through the pusher housing (3) and is fixedly connected to the motor shaft of the second motor (18), and a sealed bearing is arranged between the screw pusher and the pusher housing (3). The screw pusher (25) is composed of a cylinder and a spiral sheet, and the spiral sheet is wound in a threaded shape and arranged on the side of the cylinder. The outer contour diameter of the spiral sheet is slightly smaller than the inner side diameter of the pusher housing (3), so that the peanuts can be effectively pushed to achieve efficient and continuous material transportation; The blocking plate (20) is fixedly placed at the other end of the second electric push rod (19), and the width of the blocking plate (20) gradually decreases from the top to the bottom. The design of the blocking plate (20) being clamped on the notch at the bottom (21) of the storage box is conducive to realizing automatic feeding of peanuts and controlling the feeding speed, reducing manual operation, and improving the degree of automation and production efficiency; The purpose of being able to control the amount of peanuts poured in through the feeding component, finely crushing the peanuts through the crushing component, squeezing the peanut pieces for oil extraction through the oil pressing component and then filtering them multiple times is achieved.
