Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of edible vegetable oil production, and specifically, to a screw oil press for edible vegetable oil production. Background Art

[0002] A screw oil press is a device widely used in the production of edible vegetable oil. It extracts the oil in oilseeds through mechanical extrusion, and has the advantages of high oil yield, good oil quality, simple operation, high production efficiency, etc. It is suitable for pressing various oil crops, such as peanuts, soybeans, rapeseeds, sunflower seeds, sesame seeds, etc. The working principle of the screw oil press is to utilize the rotation of the screw to make the oilseeds be subjected to the axial pushing force and radial squeezing force in the pressing chamber. The pitch of the screw gradually decreases from the feeding end to the discharging end, while the diameter gradually increases. In this way, during the process of the oilseeds moving deeper into the pressing chamber, the pressure they are subjected to gradually increases, so as to squeeze the oil out of the oilseeds. At the same time, the oilseeds generate heat due to friction with the screw and the pressing chamber wall in the pressing chamber, which raises the temperature of the oilseeds and further promotes the separation of the oil.

[0003] In the prior art, when feeding oilseeds into the oil press, if the feeding speed of the oilseeds is too fast, the oilseeds will accumulate at the feeding port and cannot enter the pressing chamber in time, resulting in blockage. When feeding, if it is not possible to ensure continuous and uniform feeding, intermittent or uneven feeding, it is easy to make the pressure in the pressing chamber unstable, leading to blockage of the oilseeds in the pressing chamber.

The triangular plate on the side of the collecting shell can clean the grease attached to the inner side of the filter shell when it moves with the collecting shell, preventing excessive grease from attaching to the filter efficiency and quality, while also reducing the workload and frequency of manual cleaning.

[0015] 4. The screw oil press for producing edible vegetable oil is provided with a moving component. By pushing the slider to drive the round rod and the moving rod to move, the impurities blocked in the filter hole of the filter housing can be pushed out to ensure that the filter hole is unobstructed.

[0025] As Figures 1 to 5 shown, it shows a screw oil press for edible vegetable oil production in the embodiments of this disclosure, including: A main body 1, a control component 2 is fixedly connected to the top of the main body 1, receiving components 4 are fixedly connected to both sides of the main body 1, and a slag discharging component 5 is fixedly connected to the inside of the main body 1; A transmission component 3, which is used for performing screw oil pressing work on oil materials. The bottom of the transmission component 3 is fixedly connected to the top of the main body 1, and an oil filtering component 6 is arranged below the transmission component 3, and the bottom of the oil filtering component 6 is fixedly connected to the top of the main body 1; The transmission component 3 includes a pressing mechanism 31. One end of the pressing mechanism 31 is rotatably connected to the side of the main body 1, the other end of the pressing mechanism 31 is fixedly connected to an adjusting mechanism 32, a supporting mechanism 34 is fixedly connected to the side of the pressing mechanism 31, the bottom of the supporting mechanism 34 is fixedly connected to the top of the main body 1, and a feeding cylinder 33 is fixedly connected to the side of the pressing mechanism 31 away from the supporting mechanism 34. A material scattering mechanism 35 is rotatably connected to the inside of the feeding cylinder 33; The pre-treated oil materials are added into the feeding cylinder 33 of the main body. The oil materials in the hopper enter the pressing mechanism 31 under the action of gravity. Through the material scattering mechanism 35, the speed and flow rate of the oil materials entering the squeezing chamber are controlled to ensure uniform and stable feeding; The oil material entering the pressing mechanism 31 advances along the axis of the pressing chamber under the action of the rotating screw. Since the pitch of the screw gradually decreases from the feed end to the discharge end while the diameter gradually increases, the extrusion pressure on the oil material gradually increases during its advancement. At the same time, the oil material generates heat due to friction with the screw and the pressing chamber wall, causing the temperature of the oil material to rise. Under the combined action of high temperature and high pressure, the oil cells are damaged, and the oil is extruded from the oil material and flows out through the oil discharge gaps around the pressing chamber; As Figure 4 shown, the bulk material mechanism 35 includes a bottom plate 351 and a top plate 353. The sides of the bottom plate 351 and the top plate 353 are fixedly connected to the inner side of the feeding cylinder 33. A bulk material rack 354 is rotatably connected to the top of the bottom plate 351 and the bottom of the top plate 353. A motor 352 is fixedly connected to the bottom of the bottom plate 351. The output end of the motor 352 is fixedly connected to the bottom of the bulk material rack 354. A bulk material shaft 355 is rotatably connected to the inner side of the bulk material rack 354. A bulk material rod 356 is fixedly connected to one end of the bulk material shaft 355 away from the bulk material rack 354. A contact assembly 357 is fixedly connected to one side of the bulk material rack 354 close to the inner wall of the feeding cylinder 33; When the pretreated oil material is placed in the feeding cylinder 33, by starting the motor 352, the output end of the motor 352 drives the bulk material rack 354 to rotate in the feeding cylinder 33, so that the bulk material rack 354 agitates the oil material entering the feeding cylinder 33. By arranging the bulk material shaft 355 and the bulk material rod 356 on the bulk material rack 354, when the bulk material rod 356 agitates the oil material in the feeding cylinder 33, the bulk material shaft 355 drives the bulk material rod 356 to turn over the oil material in the feeding cylinder 33. At the same time, when the bulk material rack 354 rotates, it can drive the contact assembly 357 to contact and move with the inner wall of the feeding cylinder 33, thereby cleaning the inner wall of the feeding cylinder 33 by contact; The rotation of the bulk material rack 354 enables the oil material to be promptly agitated and dispersed after entering the feeding cylinder 33, avoiding the accumulation of the oil material near the feed inlet, thereby preventing blockage caused by uneven feeding or local accumulation, and ensuring that the oil material can continuously and stably enter the pressing chamber; If the oil material forms lumps due to moisture or other reasons, the turning of the bulk material rod 356 and the bulk material shaft 355 can break up the lumped oil material, enabling the oil material to enter the pressing chamber in a loose state, further reducing the risk of blockage; As Figure 5As shown, the contact component 357 includes a contact frame 3571. Both the upper and lower sides of the contact frame 3571 are fixedly connected to the inner side of the bulk material rack 354. A contact shaft 3574 is slidably connected to the inner side of the contact frame 3571. The other end of the contact shaft 3574 is fixedly connected to a contact plate 3573. The side surface of the contact plate 3573 is in contact with the inner side of the contact frame 3571. A scraping plate 3575 is fixedly connected to the side of the contact plate 3573 away from the contact shaft 3574. A first spring 3572 is sleeved on the contact shaft 3574. One end of the first spring 3572 is fixedly connected to the contact frame 3571, and the other end of the first spring 3572 is fixedly connected to the contact plate 3573; When the bulk material rack 354 rotates following the output end of the motor 352, it drives the contact frame 3571 to rotate. Thus, the contact frame 3571 drives the scraping plate 3575 to contact and rotate with the inner wall of the feeding cylinder 33 through the contact shaft 3574 and the contact plate 3573. When the bulk material rack 354 agitates the oil in the feeding cylinder 33, it can drive the scraping plate 3575 to clean the inner wall of the feeding cylinder 33. At the same time, when the contact extrusion force between the scraping plate 3575 and the inner wall of the feeding cylinder 33 is greater than the tensile force of the first spring 3572, the first spring 3572 contracts. Thus, the first spring 3572 pulls the contact plate 3573 to move towards the contact frame 3571, thereby avoiding excessive extrusion force between the scraping plate 3575 and the inner wall of the feeding cylinder 33 and preventing damage to the scraping plate 3575; While the bulk material rack 354 rotates to agitate the oil, the scraping plate 3575 can contact and rotate with the inner wall of the feeding cylinder 33, timely cleaning the oil, impurities, etc. attached to the inner wall of the feeding cylinder 33 to prevent their accumulation. This not only helps to keep the inside of the feeding cylinder 33 clean and hygienic but also avoids the growth of bacteria and the generation of odors due to oil residue, affecting the quality of the oil; As Figures 6 to 10 As shown, it shows another embodiment of the present disclosure. The oil filtering component 6 includes an oil filtering plate 61. The bottom of the oil filtering plate 61 is fixedly connected to the top of the main body 1. An arc-shaped plate 62 is fixedly connected to the middle of the top of the oil filtering plate 61. Filtering mechanisms 63 are fixedly connected to both sides of the oil filtering plate 61. A cleaning mechanism 64 is fixedly connected to the side of the filtering mechanism 63 away from the oil filtering plate 61; The crude oil flowing out of the pressing chamber enters the oil filtering plate 61. By providing the arc-shaped plate 62 in the middle of the top of the oil filtering plate 61, the crude oil evenly flows out to both sides of the oil filtering plate 61, avoiding the concentration of the crude oil in a certain area of the oil filtering plate 61, reducing the phenomenon of oil splashing, and keeping the working environment clean. The crude oil flows into the receiving component 4 through the filtering mechanism 63. When the filtering mechanism 63 is blocked, the cleaning mechanism 64 can clean the filtering mechanism 63; As Figure 7As shown, the filter mechanism 63 includes a filter housing 631, the side of the filter housing 631 is fixedly connected to the inner side of the oil filter plate 61, the filter housing 631 is evenly provided with filter holes 632 on the side away from the oil filter plate 61, magnet grooves 633 are provided on both sides of the inner cavity of the filter housing 631, and a sliding groove 634 is provided at the bottom of the inner cavity of the filter housing 631, and a collecting assembly 635 is slidably connected to the inner side of the sliding groove 634; The crude oil entering the oil filter plate 61 is separated by the arc plate 62 and flows to both sides of the oil filter plate 61, so that the crude oil flows out through the filter holes 632 of the filter housing 631, thereby filtering the impurities in the crude oil. When a large amount of impurities are screened out from the inner side of the filter housing 631, the collecting assembly 635 can be pushed to move in the sliding groove 634, thereby collecting the impurities screened out from the inner cavity of the filter housing 631. like Figure 8 As shown, the collecting assembly 635 includes a baffle 6351, the bottom of the baffle 6351 is slidably connected to the inner side of the sliding groove 634 through a stopper, both sides of the baffle 6351 are fixedly connected to a collecting shell 6352, the side of the collecting shell 6352 is evenly provided with through holes 6354, and a side of the collecting shell 6352 away from the baffle 6351 is fixedly connected to a triangular plate 6353; When the filter housing 631 performs screening for a long time and a large amount of impurities are screened out in the inner cavity of the filter housing 631, the baffle 6351 is pushed so that the baffle 6351 moves in the sliding groove 634 through the limit block, so that the baffle 6351 drives the collecting housing 6352 to collect the impurities screened out in the inner cavity of the filter housing 631. A triangular plate 6353 is provided on the side of the collecting housing 6352. When the baffle 6351 drives the collecting housing 6352 to move, the triangular plate 6353 can move against the inner side of the filter housing 631, so as to clean the grease attached to the inner side of the filter housing 631. The collecting housing 6352 is driven by the baffle 6351 to continuously move in the inner cavity of the filter housing 631 until the collecting housing 6352 is against the magnet slot 633, so that the collecting housing 6352 collects and processes the impurities screened out in the inner cavity of the filter housing 631. like Figure 9As shown in the figure, the cleaning mechanism 64 includes two fixing brackets 641 and a round rod 646. The inner sides of the fixing brackets 641 are fixedly connected to the side of the filter housing 631 away from the oil filter plate 61. A sliding groove 642 is formed in the middle of the side of the fixing bracket 641. A connecting shaft 643 is fixedly connected to the inner side of the sliding groove 642. A slider 644 is slidably connected to the side of the connecting shaft 643. The side of the slider 644 is slidably connected to the inner side of the sliding groove 642. A second spring 645 is sleeved on the connecting shaft 643. One end of the second spring 645 is fixedly connected to the side of the slider 644, and the other end of the second spring 645 is fixedly connected to the inner wall of the sliding groove 642. Both ends of the round rod 646 are fixedly connected to the side of the slider 644. A moving component 647 is fixedly connected to the side of the round rod 646 close to the filter housing 631. The moving component 647 is concentric with the through hole 6354; When the filter housing 631 filters crude oil for a long time and the filter holes 632 on the filter housing 631 are blocked by impurities and the speed of the crude oil passing through is slow, by pushing the slider 644 to move in the sliding groove 642, and at the same time, the slider 644 drives the moving component 647 through the round rod 646 to move towards the filter holes 632 on the filter housing 631; As Figure 10 shown in the figure, the moving component 647 includes a moving rod 6471. One end of the moving rod 6471 is fixedly connected to the side of the round rod 646 close to the oil filter plate 61. A relief groove 6472 is formed in the side of the moving rod 6471. A sliding sleeve 6473 is slidably connected to the side of the moving rod 6471. The sliding sleeve 6473 is slidably connected to the inner side of the relief groove 6472 through a fixing pin. A scraping plate 6475 is fixedly connected to the side of the sliding sleeve 6473. A round plate 6474 is fixedly connected to the side of the moving rod 6471 close to the round rod 646. A third spring 6476 is sleeved on the moving rod 6471. One end of the third spring 6476 is fixedly connected to the round plate 6474, and the other end of the third spring 6476 is fixedly connected to the scraping plate 6475; When pushing the slider 644 to drive the round rod 646 to move towards the filter hole 632, at the same time, the round rod 646 drives the moving rod 6471 to move towards the filter hole 632, so that the moving rod 6471 ejects the impurities blocking the filter hole 632 in the filter housing 631. At the same time, when pushing the slider 644 to drive the round rod 646 to continuously move in the filter hole 632, the moving rod 6471 drives the scraping plate 6475 to clean and contact the inner wall of the filter hole 632, so as to avoid a large amount of grease remaining on the inner wall of the filter hole 632 during long-term filtering work, which may cause a blocking phenomenon; When the scraping plate 6475 moves in contact with the inner wall of the filtering hole 632, when the extrusion force between the scraping plate 6475 and the grease attached to the inner wall of the filtering hole 632 is greater than the tensile force of the third spring 6476, the third spring 6476 pulls the scraping plate 6475, so that the scraping plate 6475 moves towards the circular plate 6474 through the sliding sleeve 6473, thereby avoiding the phenomenon that the extrusion force between the scraping plate 6475 and the inner wall of the filtering hole 632 is too large, which may cause damage to the inner wall of the filtering hole 632; After cleaning the filtering hole 632, the extrusion force on the slider 644 can be released, so that the slider 644 is driven by the reset of the second spring 645 to perform a reset operation in the sliding groove 634, so that the slider 644 drives the moving rod 6471 to perform a reset movement through the round rod 646, thereby avoiding the moving rod 6471 interfering with the normal outflow speed of the crude oil.

[0026] Specific working process: Add the pre-treated oil material into the feeding cylinder 33 of the main body. The oil material in the hopper enters the pressing mechanism 31 under the action of gravity. Through the material scattering mechanism 35, control the speed and flow rate of the oil material entering the pressing chamber to ensure uniform and stable feeding; The oil material entering the pressing mechanism 31 is pushed forward along the pressing chamber under the action of the rotating screw. Since the pitch of the screw gradually decreases from the feeding end to the discharging end, and the diameter gradually increases, the extrusion force received by the oil material gradually increases during the forward movement. At the same time, the friction between the oil material and the screw and the pressing chamber wall generates heat, increasing the temperature of the oil material. Under the combined action of high temperature and high pressure, the oil cells are damaged, and the oil is squeezed out of the oil material and flows out through the oil outlet gaps around the pressing chamber; The crude oil flowing out of the pressing chamber enters the oil filtering component 6; The oil residue cake after pressing is discharged from the slag discharging component 5 of the oil press. The slag discharging port is usually provided with an adjusting device, which can adjust the thickness and oil content of the cake according to needs.
