Description

Technical Field

[0001] This utility model relates to the field of oil press technology, specifically to a feeding device for a screw oil press. Background Technology

[0002] In traditional oil pressing processes, the impurity removal device and the oil pressing device are often configured separately to achieve efficient cleaning and oil pressing. However, this process is only suitable for large-scale automated production lines. In real life, due to technological and geographical limitations, many rural areas often adopt small-scale oil pressing methods. Due to scale and technological limitations, oil pressing equipment that integrates cleaning and pressing is more practical. To address the need for integrated oil pressing equipment that combines cleaning and pressing in the aforementioned rural areas, Chinese Patent Publication No. CN222807680U discloses a large-scale CNC oil press, including an oil press body, a feeding hopper, support legs, a screw conveyor, a support plate, a discharge pipe, a cleanup mechanism, and a stirring mechanism. The feeding hopper is located on one side of the oil press body and has a feed inlet with a feed control valve inside. Multiple support legs are fixedly installed between the feeding hopper and the oil press body. The screw conveyor is fixedly installed on the oil press body, with both ends connected to the feeding hopper and the oil press body, respectively. The support plate is fixedly installed inside the feeding hopper. This technical solution solves the problem in related technologies where impurities in the oilseeds affect the quality of the extracted oil during the pressing process. In the above scheme, by setting up a cleaning mechanism, the blower can blow air into the oil in the feed hopper, so that the impurities in the oil are discharged through the screen under the action of the wind, thus facilitating the cleaning of the oil. However, the blower blowing the oil to remove impurities cannot effectively solve the problem of residual particulate impurities in the oil. Therefore, we propose a feeding device for a screw oil press. Utility Model Content

[0003] To solve the above-mentioned technical problems, this application provides a feeding device for a screw oil press, including a base, an oil pressing roller mounted on the base, an equipment cabinet disposed on one side of the base, an oil receiving tray disposed below the oil pressing roller, an oil separating tray disposed below the oil receiving tray, an oil storage cylinder disposed below the oil separating tray, and a feeding cylinder mounted on the oil pressing roller. A separation mechanism is provided inside the feeding cylinder. The separation mechanism includes a middle separation plate, an upper separation plate disposed above the middle separation plate, and a lower separation plate disposed below the middle separation plate. Cleaning rods are provided on both the upper and lower separation plates.

[0004] In some embodiments, the upper separation plate is provided with a first filter hole, the middle separation plate is provided with a second filter hole, and the lower separation plate is provided with a third filter hole, and the number of the first filter hole, the second filter hole, and the third filter hole is provided in a plurality.

[0005] In some embodiments, the pore size of the first filter pore is larger than that of the second filter pore, and the pore size of the third filter pore is smaller than that of the second filter pore.

[0006] In some embodiments, a material blocking block is provided between the middle separation disk and the upper separation disk, and the middle separation disk and the upper separation disk are connected by the material blocking block. A connecting column is provided between the middle separation disk and the lower separation disk, and the middle separation disk and the lower separation disk are connected by the connecting column.

[0007] In some embodiments, the middle separating disc is in the shape of a sloping cone, the upper separating disc is provided with a fixing block, the bottom of the fixing block is provided with a telescopic cylinder, the output end of the telescopic cylinder is provided with a baffle post, and the baffle post is slidably engaged with the connecting post.

[0008] In some embodiments, the feeding cylinder is provided with a concave groove, and the upper separation plate, middle separation plate and lower separation plate are all provided with sliding support blocks. The sliding support blocks are provided with rollers, and the sliding support blocks and rollers cooperate with the concave groove.

[0009] In some embodiments, the upper separation plate, the middle separation plate, and the lower separation plate are each provided with a connector block, and a connecting rod is provided between the connector blocks.

[0010] This utility model has at least the following beneficial effects: 1. This utility model combines a multi-stage filter structure with high-frequency vibration through upper, middle and lower three-stage separation discs to form a dual separation mechanism. Large particles of impurities are intercepted by the upper separation disc, small particles of impurities are separated by vibration or specific gravity difference through the middle separation disc, and fine impurities are collected by the lower separation disc. This solves the problem that traditional wind-powered impurity removal is difficult to handle hard impurities, significantly reduces the risk of wear on the oil pressing rollers by hard objects such as stones, and at the same time avoids impurities breaking and mixing into the oil, ensuring the purity of the oil and the life of the equipment.

[0011] 2. This utility model adopts a sloping conical structure for the middle separation plate, combined with the telescopic control of the baffle column, to achieve automatic guidance and flow of the material after impurity removal, avoiding blockage. The upper, middle and lower separation plates are connected by rollers with sliding support blocks and concave grooves to maintain stable displacement under high-frequency vibration, reducing mechanical wear and balancing impurity removal efficiency and equipment durability. It is especially suitable for the continuous operation needs of small workshops in towns and villages, reducing maintenance costs and improving the practicality of integrated equipment.

[0014] 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.

[0015] Example 1: Please see Figure 1-5 This utility model provides a technical solution: a feeding device for a screw oil press, including a base 4, an oil pressing roller 2 installed on the base 4, an equipment cabinet 7 set on one side of the base 4, an oil receiving tray 3 set below the oil pressing roller 2, an oil separating tray 5 set below the oil receiving tray 3, an oil storage cylinder 6 set below the oil separating tray 5, and a feeding cylinder 1 installed on the oil pressing roller 2. A separation mechanism 8 is provided inside the feeding cylinder 1. The separation mechanism 8 includes a middle separation tray 89, an upper separation tray 81 set above the middle separation tray 89, and a lower separation tray 88 set below the middle separation tray 89. Cleaning rods 82 are provided on both the upper separation tray 81 and the lower separation tray 88. The feeding cylinder 1 serves as the channel for materials to enter the equipment, accommodates the separation mechanism 8, and guides the material flow to the oil pressing roller 2. A concave sliding groove 11 is opened on the inner wall, which cooperates with the sliding support block 95 of the separation disc to ensure vibration stability. The separation mechanism 8 achieves efficient removal of hard impurities such as stones in the oil through three-stage filtration and vibration separation. The upper separation disk 81 is provided with a first filter hole 86, the middle separation disk 89 is provided with a second filter hole 93, and the lower separation disk 88 is provided with a third filter hole 87. The number of the first filter hole 86, the second filter hole 93 and the third filter hole 87 are all provided in a certain amount. The diameter of the first filter hole 86 is larger than that of the second filter hole 93, and the diameter of the third filter hole 87 is smaller than that of the second filter hole 93; The upper separation plate 81 initially filters large particles of impurities. The diameter of the first filter hole 86 is larger than that of rapeseed, allowing rapeseed to pass through but intercepting large stones. The fixed block 83 is equipped with a telescopic cylinder 90. The material is spread flat on the upper separation plate 81. The connecting rod 9 drives high-frequency vibration. Rapeseed falls into the middle separation plate 89 through the first filter hole 86, while large stones are intercepted. A material blocking block 80 is provided between the middle separation plate 89 and the upper separation plate 81, and the middle separation plate 89 and the upper separation plate 81 are connected by the material blocking block 80. A connecting column 91 is provided between the middle separation plate 89 and the lower separation plate 88, and the middle separation plate 89 and the lower separation plate 88 are connected by the connecting column 91. The material blocking block 80 is connected to the upper and lower separation discs 88 via the separation port 85 and controls the discharge of impurities. It is located between the middle separation disc 89 and the upper separation disc 81. The separation port 85 can be blocked externally. When removing impurities, the separation port 85 is closed to prevent rapeseed leakage. When cleaning impurities, it is opened and used in conjunction with the cleaning rod 82 to discharge impurities. The middle separation disc 89 filters smaller impurities in the second stage, using the difference in specific gravity to separate impurities that are close to the size of rapeseed. The sloping conical shape facilitates the automatic rolling of material onto the oil pressing roller 2. The second filter hole 93 has a diameter smaller than that of rapeseed, allowing small impurities to pass through but intercepting rapeseed. The connecting column 91 connects to the lower separation disc 88 and works with the baffle column 92 to control the feeding. Vibration causes rapeseed and stones to move at different amplitudes. Stones are easily stuck in the second filter hole 93. High-frequency vibration or the impact of rapeseed causes the stuck stones to fall into the lower separation disc 88. After the impurity removal is completed, the baffle column 92 retracts, and the material rolls into the oil pressing roller 2 along the slope. The middle separation plate 89 is a sloping cone shape. A fixed block 83 is provided on the upper separation plate 81. A telescopic cylinder 90 is provided at the bottom of the fixed block 83. A baffle post 92 is provided on the output end of the telescopic cylinder 90. The baffle post 92 is slidably engaged with the connecting post 91. The lower separation plate 88 collects the finest impurities such as dust and debris. The third filter hole 87 has the smallest diameter, further filtering out fine impurities. The sweeping rod 82 has a fan-shaped design and is driven to rotate by a motor. It receives fine impurities falling from the middle separation plate 89. The rotation of the sweeping rod 82 pushes the impurities toward the separation port 85 and discharges them out of the device through the separation blocking block 84. The upper separation plate 81, the middle separation plate 89 and the lower separation plate 88 are all provided with connector blocks 94, and connecting rods 9 are provided between the connector blocks 94; Oil separator 5 and oil storage cylinder 6 collect and store the pressed oil, oil receiving plate 3 receives the oil squeezed out by oil pressing roller 2, and oil separator 5 diverts the oil to oil storage cylinder 6 to complete the oil storage. The sweeping rod 82 cleans the residual impurities on the separation disc. Its fan-shaped design covers the surface of the separation disc. The motor drives the sweeping rod 82 to rotate, concentrating the impurities into the separation port 85. The separation blocking block 84 then helps to discharge the impurities. The connecting rod 9 and the connector block 94 transmit vibration power to drive the separation disc to vibrate. The connector block 94 connecting each separation disc is driven by an external power source, such as a motor. The external power drives the separation disc to vibrate at high frequency through the connecting rod 9, which promotes material filtration and impurity separation. The telescopic cylinder 90 and the baffle column 92 control the timing of material falling from the middle separation plate 89. The telescopic cylinder 90 is installed on the fixed block 83 of the upper separation plate 81. The baffle column 92 and the connecting column 91 are in sliding cooperation. When removing impurities, the baffle column 92 closes the connecting column 91 to prevent the material from falling. After completion, the cylinder retracts, the baffle column 92 disengages, and the material rolls into the oil pressing roller 2 along the slope due to gravity. The material enters the feeding cylinder 1 and is spread evenly on the upper separating plate 81. The upper separating plate 81 vibrates, and the rapeseed falls into the middle separating plate 89 through the first filter hole 86. Large stones are intercepted. The middle separating plate 89 vibrates, and small stones are stuck in the second filter hole 93 or separated by the difference in specific gravity. The rapeseed is temporarily stored in the middle separating plate 89. The baffle column 92 closes the connecting column 91. After the impurities are separated, the baffle column 92 opens, and the material rolls into the oil pressing roller 2 along the slope. The lower separating plate 88 collects fine impurities, and the cleaning rod 82 cleans and discharges the impurities. The pure material enters the oil pressing roller 2, and the squeezed oil is stored in the oil storage cylinder 6 through the oil separating plate 5.

[0016] Example 2: Based on Embodiment 1, this utility model provides a technical solution: a feeding device for a screw oil press, wherein a concave groove 11 is provided on the upper feeding cylinder 1, and sliding support blocks 95 are provided on the upper separating disc 81, the middle separating disc 89 and the lower separating disc 88, and rollers 96 are provided on the sliding support blocks 95, and the sliding support blocks 95 and rollers 96 cooperate with the concave groove 11. The sliding support block 95 and the roller 96 ensure stable vibration of the separation disc and reduce mechanical wear. They are installed on the edge of the separation disc and embedded in the concave groove 11 of the feed cylinder 1. The roller 96 rolls in the groove to reduce friction and maintain smooth movement during vibration. When the device is running, the material is put into the feeding cylinder 1. The material flows into the oil pressing roller 2 through the feeding cylinder 1. After being squeezed by the oil pressing roller 2, the material is oiled and flows onto the oil receiving plate 3. The oil on the oil receiving plate 3 is divided by the oil separating plate 5 and then flows into the oil storage cylinder 6 below, thus completing the oil pressing. The material is poured into the feeding cylinder 1. Since the material may contain impurities such as stones, especially hard impurities, they will damage the extrusion roller after entering the extrusion roller. The fine particles generated by the extrusion will also enter the oil, affecting the quality of the oil. When rapeseed enters the feeding cylinder 1, it spreads evenly on the upper separating disc 81. Driven by an external power source, the connecting rod 9 drives the connector block 94, which in turn causes the upper separating disc 81, the middle separating disc 89, and the lower separating disc 88 to vibrate. This causes the rapeseed spread on the upper separating disc 81 to fall onto the middle separating disc 89 through the first filter hole 86. The diameter of the first filter hole 86 is large enough to allow the rapeseed to pass through, leaving larger stones on the upper separating disc 81. Under the vibration of the middle separating disc 89, since the diameter of the second filter hole 93 is smaller than that of the rapeseed, smaller stones fall onto the lower separating disc 88. It is possible that there are some stones with a diameter similar to that of the rapeseed in the impurities. The stones and rapeseed will be separated together onto the middle separation plate 89. Due to the vibration generated by the drive of the connecting rod 9, the stones and rapeseed on the middle separation plate 89 will vibrate at different amplitudes using the specific gravity method. Under high-frequency vibration, the stones are more likely to get stuck in the second filter hole 93, so that the middle separation plate 89 can remove impurities from the rapeseed to a certain extent through vibration, and can better remove impurities from the rapeseed. When the material is fed externally, the baffle column 92, driven by the telescopic cylinder 90, cooperates with the connecting column 91 to block the rapeseed on the middle separation plate 89. After the impurities are separated, the telescopic cylinder 90 drives the baffle column 92 to separate and open from the connecting column 91. Since the middle separation plate 89 is shaped like a sloping cone, the rapeseed after impurity removal can roll into the oil pressing roller through the connecting column 91 under the influence of gravity for subsequent oil pressing. Through high-frequency vibration and the impact of falling rapeseed, the stones stuck in the second filter hole 93 can fall onto the lower separation plate 88 and be collected along with the stones on the lower separation plate 88. The built-in motor is started to drive the sweeping rods 82 on the upper separation plate 81 and the lower separation plate 88 to rotate and collect the stones on the upper separation plate 81 and the lower separation plate 88. Since the sweeping rods 82 are fan-shaped, the collected stones can finally flow out of the feed cylinder 1 through the separation port 85 on the separation blocking block 84. When not in use, the separation port 85 can be blocked externally to prevent rapeseed from flowing out. The separation blocking block 84 can assist in blocking the separation port 85. Since the upper separating disk 81, the middle separating disk 89, and the lower separating disk 88 operate in a high-frequency vibration mode under the drive of the connecting rod 9, the sliding support block 95 set on the edge of the upper separating disk 81, the middle separating disk 89, and the lower separating disk 88 cooperate with the concave sliding groove 11 to ensure stable vibration of the upper separating disk 81, the middle separating disk 89, and the lower separating disk 88. The sliding support block 95 is equipped with a roller 96, which is rotatably connected to the sliding support block 95. The roller 96 can rotate relative to the inner wall of the concave sliding groove 11, which also ensures the stability of the vibration.
