Description

Technical Field

[0001] The present invention relates to the field of separation, and specifically to a separation device and method for pretreatment of raw materials for edible oil processing. Background Art

[0002] Edible oil, also known as "cooking oil", refers to animal or vegetable oils used in the process of making food. It is liquid at room temperature. Due to reasons such as raw material sources, processing techniques, and quality, common edible oils are mostly vegetable oils, including rapeseed oil, peanut oil, corn oil, olive oil, camellia oil, palm oil, sunflower oil, soybean oil, sesame oil, linseed oil (flaxseed oil), grape seed oil, walnut oil, peony seed oil, and so on.

[0003] After retrieval, a device for separating oil residues in edible oil processing is disclosed, with the publication number: CN221049086U; This device is essentially a solid-liquid separation equipment. The deficiency of this equipment is that the device realizes the filtration of edible oil through the rotation of the filter plate. This kind of filtration method can filter out most of the oil residues, but there will still be a certain amount of fine oil residues in the edible oil, and its purity is relatively low; Secondly, this kind of filtration method uses extrusion. When extruding, the oil residues will be extruded from the filter holes due to the force, resulting in the mixing of the filtered edible oil and a small amount of oil residues.

[0010] As a further solution of the present invention: The lifting component includes a threaded cylinder rotatably installed in an installation groove, the four threaded cylinders are connected by a transmission chain, a hand wheel is rotatably installed on one side of the separation box, and the rotating shaft of the hand wheel is connected to one of the threaded cylinders through a belt; A threaded rod in threaded fit with the threaded cylinder is installed in the threaded cylinder, and the threaded rod is fixed to the lifting frame.

[0011] As a further solution of the present invention: A splash-proof plate is further fixed to the bottom of the lifting frame, and the splash-proof plate is in sliding fit with the collection cavity.

[0012] As a further solution of the present invention: The driving component includes a transmission cylinder penetrating through the bottom of the separation box and sealingly rotatably connected thereto, a transmission rod is slidably installed in the transmission cylinder, and the transmission rod is coaxially fixed to the bottom of the impurity storage box; First transmission teeth are circumferentially and equidistantly fixed inside the transmission cylinder, second transmission teeth are circumferentially and equidistantly fixed on the transmission rod, the second transmission teeth are engaged with the first transmission teeth, and arc-shaped surfaces are arranged on the opposite sides of the second transmission teeth and the first transmission teeth; A motor is fixed at the bottom of the separation box, and the motor is coaxially fixed with the transmission cylinder.

[0013] The present invention also provides a separation method for the pretreatment of edible oil processing raw materials.

Secondly, in terms of the cleaning after the use of the present invention, through the lifting of the lifting assembly, the entire structure for separation and filtration can be exposed, making it easier to clean.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In addition, the elements in the present invention are referred to as "fixed to" or "disposed on" another element, which can be directly on another element or there may be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to another element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0029] Example 1. Please refer to Figures 1 - 11 , a separation device for the pretreatment of edible oil processing raw materials, including a separation tank 1 and a plurality of legs 101 fixed to the bottom of the separation tank 1. A conical collection cavity 20 is arranged in the separation tank 1, and a discharge pipe 3 communicating with the collection cavity 20 is fixed to the bottom of the separation tank 1; the discharge pipe 3 is used for discharging the separated edible oil; Four mounting grooves 103 are opened at the four corners of the separation tank 1, and lifting components are installed in the mounting grooves 103; The lifting frame 9 is installed on the top of the separation tank 1 through the lifting components. A support frame 10 is fixed to the lifting frame 9. A separation component is installed on the lifting frame 9 and the support frame 10, and the separation component is connected to a driving component installed at the bottom of the separation tank 1; A top cover 102, the top cover 102 is fixed to a connecting column 14 fixed to the lifting frame 9. A feeding hopper support 401 is fixed inside the top cover 102. A feeding hopper 4 is fixed to the feeding hopper support 401. A feeding pipe 402 communicating with the feeding hopper 4 is fixed to the bottom of the feeding hopper 4, and the feeding pipe 402 is inserted into the separation component.

[0030] In the embodiment of the present invention, edible oil is added to the feeding hopper 4 and moves into the separation component under the guidance of the feeding pipe 402; The driving component is started. When the driving component works, it drives the separation component to work. When the separation component works, impurities in the edible oil are separated, and the separated impurities are centrally collected; The separation component can be driven to rise by the lifting component to facilitate the cleaning of the impurities separated in the separation component.

[0031] Example 2. The difference from Example 1 is that the separation component includes a separation drum 11. The separation drum 11 is rotatably installed on the lifting frame 9. A transmission pipe 15 is coaxially arranged inside the separation drum 11. The transmission pipe 15 is rotatably connected to the support frame 10. The separation drum 11 and the transmission pipe 15 are connected by a transmission member; the feeding pipe 402 is inserted into the separation drum 11; A spiral conveying and scraping blade 16 is coaxially fixed on the transmission pipe 15, and through holes are formed in the spiral conveying and scraping blade 16; A impurity storage box 12 communicating with the bottom of the separation drum 11 is detachably installed at the bottom of the separation drum 11. Sieve holes are formed in both the impurity storage box 12 and the separation drum 11, and the impurity storage box 12 is connected to the driving assembly; The spiral conveying and scraping blade 16 is in clearance fit with the inner wall of the separation drum 11.

[0032] In the embodiment of the present invention, when the driving assembly works, it drives the impurity storage box 12 to rotate. When the impurity storage box 12 rotates, it drives the separation drum 11 to rotate synchronously. When the separation drum 11 rotates, it drives the transmission pipe 15 in the opposite direction through a transmission member, and then drives the spiral conveying and scraping blade 16 to rotate in the opposite direction, so that the rotation directions of the separation drum 11 and the spiral conveying and scraping blade 16 are opposite; When adding edible oil into the feeding hopper 4, under the guidance of the feeding pipe 402, it flows into the separation drum 11 and is on the spiral conveying and scraping blade 16. The edible oil will flow towards the bottom of the separation drum 11 due to the through holes formed in the spiral conveying and scraping blade 16; As the separation drum 11 rotates, the edible oil will be thrown out of the separation drum 11 by centrifugal force, and impurities will be filtered out through the sieve holes of the separation drum 11. The edible oil thrown out of the separation drum 11 will be in the collection cavity 20; The rotation of the transmission pipe 15 and the spiral conveying and scraping blade 16 is essentially used to scrape off the impurities attached to the inner wall of the separation drum 11 and convey the impurities towards the bottom of the separation drum 11, so that the impurities can be centrally collected in the impurity storage box 12; Among them, the clearance fit between the spiral conveying and scraping blade 16 and the inner wall of the separation drum 11 means that there is a very small gap between the diameter of the spiral conveying and scraping blade 16 and the inner wall of the separation drum 11, so that the spiral conveying and scraping blade 16 will not contact the inside of the separation drum 11 when rotating, to reduce wear, and the impurities attached to the inner wall of the separation drum 11 can be conveyed downward by the rotation of the spiral conveying and scraping blade 16; It should be noted that the pitch of the spiral conveying and scraping blade 16 can be gradually reduced from top to bottom. Because there is a certain extrusion force during spiral conveying, when there is a large accumulation of impurities, a larger extrusion force can be applied to the impurities through the smaller pitch, and the edible oil in the impurities can be extruded as much as possible, so that more impurities can be stored in the impurity storage box 12.

[0033] The transmission member includes a gear 24 rotatably installed at the bottom of the support frame 10. The gear 24 meshes with a toothed ring 22 fixed to the inner wall of the separation drum 11, and the gear 24 is connected to the transmission pipe 15 through a chain 23; Among them, the transmission ratio between the gear ring 22 and the gear 24 is separated from the box by 1: the motor 5. Simply put, when the separation drum 11 rotates, driving the gear 24 to rotate through the gear ring 22 is to reduce speed and increase torque, enabling the separation drum 11 to rotate at a relatively high speed, while the transmission pipe 15 and the spiral conveying scraper 16 rotate slowly.

[0034] In the embodiment of the present invention, when the separation drum 11 rotates, it drives the gear 24 to rotate through the meshing of the gear ring 22 and the gear 24. The rotation direction of the gear 24 is opposite to that of the separation drum 11 and the gear ring 22. When the gear 24 rotates, it drives the transmission pipe 15 to rotate through the chain 23, thereby achieving the effect that the rotation directions of the separation drum 11, the transmission pipe 15, and the spiral conveying scraper 16 are opposite.

[0035] The bottom of the collection cavity 20 is in a conical surface, and a plurality of secondary separation grooves 21 are equidistantly arranged on the conical surface. Among them, filter holes (not shown in the figure) are provided at the bottom of the secondary separation grooves 21, so that when the edible oil flows downward along the position of the secondary separation grooves 21, fine impurities in the edible oil can be filtered out to achieve the effect of secondary filtration.

[0036] Please refer to Figure 4 In the embodiment of the present invention, when the edible oil is separated into the collection cavity 20 by the rotation of the separation drum 11, in fact, the edible oil is thrown into the collection cavity 20 and slides down along the inner wall of the collection cavity 20, and its flow rate is not fast. When the edible oil passes through the position of the secondary separation grooves 21, there is a stepped groove. The edible oil passes through the secondary separation grooves 21 in sequence and fills the upper part and then overflows into the lower secondary separation groove 21. At this time, some impurities that may be doped inside can be precipitated into the secondary separation grooves 21 through the secondary separation grooves 21; After the edible oil is separated by the separation drum 11, there are basically no impurities inside, but some relatively fine impurities cannot be effectively filtered. The characteristic that the density of the impurities is greater than that of the edible oil can be used to precipitate the impurities into the secondary separation grooves 21.

[0037] A cleaning member 13 is fixed in the impurity storage box 12; The cleaning member 13 includes four spraying pipes, which are fixed by a connecting plate between the four spraying pipes. The connecting plate is inserted into a connecting portion 1501 fixed to the bottom of the transmission pipe 15, and the spraying pipes are communicated with the transmission pipe 15.

[0038] In the embodiment of the present invention, water can be pumped into the transmission pipe 15 to make the water spray out through the spraying pipes, so as to flush out the impurities precipitated in the secondary separation grooves 21 with high-speed water. In essence, it is a process of cleaning the secondary separation grooves 21 to achieve the effect of convenient cleaning.

[0039] Embodiment 3, the distinguishing features from Embodiment 1 and / or 2 are as follows: The lifting assembly includes a threaded cylinder 7 rotatably installed in the installation groove 103. The four threaded cylinders 7 are connected by a transmission chain 6. One side of the separation box 1 is rotatably installed with a handwheel 2, and the rotating shaft of the handwheel 2 is connected to one of the threaded cylinders 7 through a belt; A threaded rod 8 that is in threaded fit with the threaded cylinder 7 is installed in the threaded cylinder 7, and the threaded rod 8 is fixed to the lifting frame 9.

[0040] In the embodiment of the present invention, by applying an external force to drive the handwheel 2 to rotate, when the handwheel 2 rotates, it drives one of the threaded cylinders 7 to rotate through the belt, so as to drive the remaining threaded cylinders 7 to rotate synchronously through the transmission chain 6, and then make the multiple threaded cylinders 7 rotate synchronously; When the threaded cylinder 7 rotates, it drives the threaded rod 8 to rise / descend vertically through the threaded fit with the threaded rod 8, so as to drive the lifting frame 9 to rise / descend vertically synchronously through the rise / descend of the threaded rod 8; When the lifting frame 9 rises / descends, it drives the separation drum 11, the support frame 10, the transmission pipe 15, and the feeding hopper 4 to move synchronously; In this embodiment, the function of driving the lifting frame 9 to rise is that when the edible oil impurities are separated by the rotation of the separation drum 11, the impurities in the separation drum 11 will move to the impurity storage box 12 for storage. After storing a certain amount, it is necessary to clean it; The above-mentioned impurity storage box 12 is detachably installed at the bottom of the separation drum 11, and its detachable method is fixed by bolts. When disassembling, the bolts used for fixing on the impurity storage box 12 can be removed, and then the impurity storage box 12 can be taken off to clean its inner wall; It should be noted that in this embodiment, the handwheel 2 can be equivalently replaced by a motor. For example, if a motor is used, the output shaft of the motor is connected to one of the threaded cylinders 7 through a belt; In this embodiment, the threaded drive for lifting has the effect of saving effort. Since the present invention considers two implementation methods, the first is to drive the threaded cylinder 7 to rotate by manually driving the handwheel 2, and the second is to use a motor. When the motor output shaft rotates, it drives the threaded cylinder 7 to rotate through a belt. When using the first driving method, the required driving force is smaller, and thus more labor-saving. When using the second method, a motor with a lower power can be used.

[0041] A splash-proof plate 17 is further fixed to the bottom of the lifting frame 9, and the splash-proof plate 17 is slidably matched with the collection cavity 20; the splash-proof plate 17 is used to throw the edible oil out of the top of the collection cavity 20 when the separation assembly is working.

[0042] The driving assembly includes a transmission cylinder 18 that penetrates the bottom of the separation box 1 and is sealingly and rotationally connected thereto. A transmission rod 19 is slidably installed in the transmission cylinder 18, and the transmission rod 19 is coaxially fixed to the bottom of the impurity storage box 12. A first transmission gear 1801 is fixedly arranged at equal intervals on the inner circumference of the transmission cylinder 18, and a second transmission gear 1901 is fixedly arranged at equal intervals on the circumference of the transmission rod 19. The second transmission gear 1901 cooperates with the first transmission gear 1801, and arc-shaped surfaces are arranged on the opposite sides of the second transmission gear 1901 and the first transmission gear 1801. A motor 5 is fixed to the bottom of the separation box 1, and the motor 5 is coaxially fixed to the transmission cylinder 18.

[0043] In the embodiment of the present invention, when the motor 5 operates, the transmission cylinder 18 is driven to rotate through the output shaft. When the transmission cylinder 18 rotates, the first transmission gear 1801 drives the second transmission gear 1901 and the transmission rod 19 to rotate synchronously, thereby driving the impurity storage box 12 and the separation drum 11 to rotate. Wherein, the transmission rod 19 and the transmission cylinder 18 can axially slide, so that when the separation drum 11 and the impurity storage box 12 rise, the transmission rod 19 is driven to rise, and when they fall, the transmission rod 19 can be inserted into the transmission cylinder 18 again to resume transmission. The first transmission gear 1801 and the second transmission gear 1901 can prevent the problem that the transmission rod 19 and the transmission cylinder 18 cannot be inserted when they are docked. It should also be noted that the motor 5 in the present invention is a high-torque servo motor. Of course, a stepping motor or a DC motor can also be selected according to actual production requirements. The present invention does not make specific limitations, as long as the driving requirements are met.

[0044] The present invention also provides a separation method for the pretreatment of edible oil processing raw materials. The separation method for the pretreatment of edible oil processing raw materials uses the separation device for the pretreatment of edible oil processing raw materials, and includes the following steps: Step 1, pour the edible oil to be separated into the feeding hopper 4, and then enter the separation drum 11 through the guidance of the feeding pipe 402. Step 2, drive the impurity storage box 12 and the separation drum 11 to rotate through the driving assembly. When the separation drum 11 rotates, the edible oil is thrown into the collection chamber 20 by centrifugal force, while the impurities remain in the separation drum 11. At the same time, the inner wall of the separation drum 11 is continuously cleaned and conveyed by the rotation of the transmission pipe 15 and the spiral conveying scraper 16 to prevent the sieve holes of the separation drum 11 from being blocked. Step 3, after the edible oil in the collection chamber 20 is secondarily separated by the secondary separation tank 21, it can be discharged through the discharge pipe 3.

A separation method for pretreatment of edible oil processing raw materials, the separation method for pretreatment of edible oil processing raw materials adopts the separation device for pretreatment of edible oil processing raw materials as described in any one of claims 1 to 8, characterized in that, It includes the following steps: Step 1, pour the edible oil to be separated into the feeding hopper (4), and then enter the separation drum (11) through the guidance of the feeding pipe (402); Step 2, drive the impurity storage box (12) and the separation drum (11) to rotate through the driving assembly. When the separation drum (11) rotates, the centrifugal force throws the edible oil into the collection cavity (20), while the impurities remain in the separation drum (11). At the same time, the inner wall of the separation drum (11) is continuously cleaned and conveyed through the rotation of the transmission pipe (15) and the spiral conveying scraper (16) to prevent the sieve holes of the separation drum (11) from being blocked; Step 3, after the edible oil in the collection cavity (20) is secondarily separated by the secondary separation tank (21), it can be discharged through the discharge pipe (3).
