Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, in particular to a solid-liquid separation device for petroleum refining. Background Art

[0002] After extraction, crude oil needs to go through refining and other processing steps before it can be processed into oil for the market. Petroleum refining involves high-temperature fractional distillation to crack crude oil into different products such as gasoline, diesel, kerosene, LPG, ethylene, asphalt, etc. Common processes for petroleum refining include atmospheric and vacuum distillation, catalytic cracking, delayed coking, oxygen cracking, solvent deasphalting, oxygen refining, and catalytic reforming. During the petroleum refining process, solid-liquid mixtures are often produced, which require solid-liquid separation.

[0003] In the prior art, in the solid-liquid separation process of oil refining, workers introduce oil from the feed port, and the resistance wire at the bottom performs high-temperature fractionation on the introduced oil.

DETAILED DESCRIPTION

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0048] The existing technology of solid-liquid separation equipment for oil refining has the following defects: when the oil is distilled and enters the solid-liquid separation stage, the oil is sticky and the solid-liquid mixture sticks to the inner wall of the equipment, resulting in waste of the oil distillation product. At the same time, the sticky solid-liquid mixture is difficult to clean;

[0049] To solve the above problems, the main concept adopted in this embodiment is: the present invention cooperates with the scraping component and the fastening component to scrape off the solid-liquid mixture adhering to the inner wall of the cylinder 1, thereby scraping off the inner wall of the cylinder 1 cleanly, reducing the waste of distillation products adhering to the inner wall of the cylinder 1, and also preventing the solid-liquid mixture adhering to the inner wall of the cylinder 1 from affecting the next oil refining, thereby improving the purity of the oil refining.

[0050] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods;

[0051] The present invention provides a solid-liquid separation device for petroleum refining, comprising a cylinder 1, a first forward and reverse motor 2, an electric heating wire 3, an oil inlet pipe 4, and a base 5. The first forward and reverse motor 2 is fixedly connected to the top of the cylinder 1, and the output shaft of the first forward and reverse motor 2 passes through the top of the cylinder 1 and is rotatably connected to the top of the cylinder 1; it is used to provide power; an oil inlet pipe 4 passes through one side of the cylinder 1 for transporting oil; an electric heating wire 3 is provided at the bottom of the cylinder 1 for providing a heat source; one end of the base 5 is fixedly connected to the bottom of the cylinder 1, and the end of the base 5 away from the cylinder 1 is in contact with the ground; and further comprising:

[0052] Scraping assembly; the scraping assembly is arranged in the cylinder 1 and is used to scrape the solid-liquid mixture on the inner wall of the cylinder 1;

[0053] Fastening assembly; the fastening assembly is arranged in the cylinder 1 and is used to change the motion state of the scraping assembly;

[0054] The staff opens the valve of the oil inlet pipe 4, and the oil is injected into the cylinder 1. At the same time as the oil is injected, the electric heating wire 3 is turned on to heat and refine the oil in the cylinder 1; after the oil injection is completed, the scraper assembly reaches the top of the oil liquid level, and the fastening assembly is used to fasten the scraper assembly to avoid the scraper assembly moving down into the oil; when the oil is refined into a solid-liquid mixture, the solid-liquid mixture is discharged from the cylinder 1, and the fastening effect of the fastening assembly on the scraper assembly is released at this time, and under the control of the electrical system, the No. 1 forward and reverse motor 2 is controlled to rotate forward, thereby driving the scraper assembly to move down. In the process of the scraper assembly moving down, the scraper assembly scrapes off the solid-liquid mixture stuck on the inner wall of the cylinder 1, thereby ensuring the cleanliness of the cylinder 1 and avoiding the solid-liquid mixture stuck on the inner wall of the cylinder 1 affecting the next oil refining, thereby improving the purity of the oil refining; it also reduces the waste of products after oil fractionation; and improves the use effect of the solid-liquid separation equipment for oil refining; the base between the cylinder 1 and the ground plays a supporting role;

[0055] In the prior art, in the solid-liquid separation process of oil refining, workers introduce oil from the feed port, and the resistance wire at the bottom performs high-temperature fractionation on the introduced oil. The solid-liquid mixture after fractionation is filtered and separated by a filter device to obtain a product without solids. However, when the oil enters the solid-liquid separation stage after fractionation, the oil is sticky, and the solid-liquid mixture sticks to the inner wall of the equipment, resulting in waste of the oil fractionation product. At the same time, the sticky solid-liquid mixture is difficult to clean.

[0056] The present invention cooperates with the scraping component and the fastening component so that the solid-liquid mixture adhering to the inner wall of the cylinder 1 is scraped off by the scraping component, thereby cleaning the inner wall of the cylinder 1, reducing the waste of distillation products adhering to the inner wall of the cylinder 1, and also preventing the solid-liquid mixture adhering to the inner wall of the cylinder 1 from affecting the next oil refining, thereby improving the purity of the oil refining.

[0057] As a specific embodiment of the present invention, the scraping assembly includes:

[0058] Screw rod 6; one end of the screw rod 6 is fixedly connected to the output shaft of the first forward and reverse motor 2;

[0059] Scraper 7; the scraper 7 is sleeved on the screw rod 6;

[0060] Ball 8; the ball 8 is provided between the screw 6 and the scraper 7;

[0061] Groove 9; The inner wall of the cylinder 1 is provided with a groove 9;

[0062] As a specific embodiment of the present invention, the fastening assembly includes:

[0063] The second forward and reverse motor 11 is fixed to the top of the scraper 7;

[0064] The flat gear 12 is fixedly connected to the output shaft of the second forward and reverse motor 11;

[0065] T-shaped chute 13; the T-shaped chute 13 is opened on the scraper 7;

[0066] The T-shaped slider 14 is arranged in the T-shaped slide groove 13;

[0067] The rack 15 is fixed to the side of the T-shaped slider 14 away from the T-shaped slot 13; the rack 15 is engaged with the flat gear 12;

[0068] No. 1 clamp 16; one end of the No. 1 clamp 16 is fixed to the top of the scraper 7, and the No. 1 clamp 16 is slidably connected to the screw rod 6;

[0069] The second clamp 17; one end of the second clamp 17 is fixed to the T-shaped slider 14; the second clamp 17 is slidably connected to the scraper 7;

[0070] When it is necessary to refine the oil, the staff opens the oil inlet pipe 4 to fill the inside with oil. At this time, under the control of the electrical system, the No. 1 forward and reverse motor 2 is controlled to rotate forward. The forward-rotating No. 1 forward and reverse motor drives the screw 6 to rotate, and then the screw 6 drives the scraper 7 to rotate. Since the T-shaped slider 14 on the top of the scraper 7 is in a locked state with the groove 9 on the inner wall of the cylinder 1, the T-shaped slider 14 limits the rotation of the scraper 7, prompting the scraper 7 to move upward along the direction of the groove 9 opened on the cylinder 1 along the screw 6. At the same time, during the rising process of the scraper 7, a cavity is formed between the scraper 7 and the bottom of the cylinder 1, generating negative pressure, which sucks the oil from the oil inlet pipe 4 into the cylinder 1, thereby accelerating the speed of oil injection;

[0071] When the scraper 7 rises along the groove 9 to the top of the groove 9, the rotation of the No. 1 forward and reverse motor 2 is stopped, the oil inlet pipe 4 is closed, and the oil filling is stopped. At this time, the staff operates the electrical system to control the No. 2 forward and reverse motor 11 to rotate forward, and the forward rotating No. 2 forward and reverse motor 11 drives the flat gear 12 to rotate. The rotating flat gear 12 drives the meshing rack 15 to move, and then drives the T-shaped slider 14 fixed on the rack 15 to move laterally along the T-shaped slide 13. In the process of movement, the No. 2 clamp 17 fixedly connected to the T-shaped slider 14 gradually approaches the screw rod 6. When the No. 2 clamp 17 contacts the No. 1 clamp 16, the No. 1 clamp 16 and the No. 2 clamp 17 are tightened to the screw rod 6, thereby fixing the scraper 7 on the screw rod 6, so that the T-shaped slider 14 and the groove 9 are released from the position limit;

[0072] After the fastening assembly fastens the scraper 7 to the screw 6, the staff operates the electrical system to control the forward and reverse motor No. 1 to rotate forward. The forward rotating motor No. 1 drives the screw 6 to rotate. The rotating screw 6 stirs the oil in the cylinder 1, causing the oil to be heated evenly, thereby accelerating the speed of oil refining.

[0073] After the oil refining is completed, the rotation of the No. 1 forward and reverse motor 2 is stopped to align the T-shaped chute 13 with the groove 9. At this time, the staff operates the electrical system to control the No. 2 forward and reverse motor 11 to reverse the rotation of the No. 2 forward and reverse motor 11. The reverse rotation of the No. 2 forward and reverse motor 11 drives the flat gear 12 to rotate in the opposite direction. The reverse rotating flat gear 12 drives the meshing rack 15 to move, and then drives the T-shaped slider 14 fixed to the rack 15 to move laterally along the T-shaped chute 13 toward the groove 9, so that the T-shaped slider 14 is engaged with the groove 9, and at the same time, the tightening effect of the No. 2 clamp 17 and the No. 1 clamp 16 on the screw rod 6 is released;

[0074] At this time, under the control of the electrical system, the forward and reverse motor 2 is controlled to reverse. Since the T-shaped slider 14 is in an engaged state with the groove 9, the rotation of the scraper 7 is restricted, prompting the scraper 7 to move downward along the direction of the groove 9 opened on the cylinder 1 along the screw 6. In the process of downward movement, the scraper 7, which is in contact with the inner wall of the cylinder 1, scrapes off the solid-liquid mixture adhering to the inner wall of the cylinder 1; thereby, the inner wall of the cylinder 1 is scraped clean, reducing the waste of the solid-liquid mixture adhering to the inner wall of the cylinder 1, and also avoiding the solid-liquid mixture adhering to the inner wall of the cylinder 1 affecting the next oil refining. The purity of oil refining is improved. Under the action of the engagement of the T-shaped slider 14 and the groove 9, the solid-liquid mixture on the groove 9 is scraped off; the ball 8 between the scraper 7 and the screw 6 removes the solid-liquid mixture on the surface of the screw 6 during the downward movement, further reducing the waste of the solid-liquid mixture adhering to the cylinder 1; at the same time, the downward moving scraper 7 also squeezes the solid-liquid mixture in the cylinder 1, thereby accelerating the discharge speed of the solid-liquid mixture from the cylinder 1, thereby improving the production efficiency of the solid-liquid separation equipment for oil refining; when it is necessary to refine the oil again, repeat the above operation.

[0075] As a specific embodiment of the present invention, a telescopic rod 18 is fixedly connected to the scraper;

[0076] During the refining of oil, the telescopic rod 18 in the scraper 7 away from the oil liquid surface will be extended to the liquid surface under the action of gravity. At this time, the rotating scraper 7 drives the telescopic rod 18 extending from the scraper 7 to rotate. The rotating telescopic rod 18 stirs the oil in the cylinder 1, so that the oil at the bottom of the cylinder 1 is fully in contact with the oil on the surface of the cylinder 1, so that the oil is evenly heated during the refining process, thereby accelerating the refining speed of the oil.

[0077] After the oil is refined into a solid-liquid mixture, during the downward movement of the scraper 7, due to the restriction of the bottom of the cylinder 1, the scraper 7 moves downward along the screw 6, gradually compressing the solid-liquid mixture in the cylinder 1, and the telescopic rod 18 extending from the scraper 7 first contacts the bottom of the cylinder 1. As the scraper 7 gradually moves downward and contacts the bottom of the cylinder 1, the telescopic rod 18 also gradually shrinks. When the solid-liquid mixture in the cylinder 1 is discharged, the scraper 7 reaches the bottom end of the groove 9, and the telescopic rod 18 on the scraper 7 is also retracted into the scraper 7; the telescopic rod 18 here does not affect the scraper 7 from scraping the remaining solid mixture on the inner wall of the cylinder 1; when the inside of the cylinder 1 is filled with oil, the scraper 7 moves upward again along the screw 6, and at this time the telescopic rod 18 in the scraper 7 retracts and contracts downward under the action of its own gravity, and repeats this cycle.

[0078] As a specific embodiment of the present invention, a filter assembly is provided on one side of the cylinder 1 for filtering the solid-liquid mixture after refining; the filter assembly includes:

[0079] Filter box 19; the filter box 19 is located on one side of the cylinder 1 and is fixedly connected to the outer surface of the cylinder 1;

[0080] The oil outlet pipe 21 passes through one side of the cylinder 1, and the end of the oil outlet pipe 21 away from the cylinder 1 extends into the filter box 19;

[0081] The baffle 22 is slidably connected to the oil outlet pipe 21;

[0082] Filter 23; The filter 23 is provided below the oil outlet pipe 21, and the filter 23 is fixedly connected to the inner wall of the filter box 19;

[0083] The slag discharge port 24 is fixedly connected to the side of the filter box 19 away from the cylinder 1;

[0084] Drain port 25; the drain port 25 is fixed to one side of the filter box 19; used to discharge the filtered oil;

[0085] When the oil refining in the cylinder 1 is completed, the staff opens the baffle 22 on the oil outlet pipe 21. Under the action of its own gravity and the scraping component, the solid-liquid mixture in the cylinder 1 is discharged from the oil outlet pipe 21 to the filter screen 23 in the filter box 19. At this time, the liquid in the solid-liquid mixture falling on the filter screen 23 flows along the holes on the filter screen 23 to the bottom of the filter box 19, while the solid particles in the solid-liquid mixture are blocked by the filter screen 23 on the surface of the filter screen 23, thereby achieving the effect of solid-liquid separation.

[0086] When the solid-liquid mixture is separated, the staff opens the drain port 25 to allow the liquid at the bottom of the filter box 19 to flow out from the drain port 25, thereby obtaining the liquid separated after refining. The solid particles remaining on the surface of the filter screen 23 after separation need to be cleaned by the staff by opening the slag discharge port 24 and using special tools to clean the solid particles accumulated on the surface of the filter screen 23, thereby improving the cleanliness of the surface of the filter screen 23 and avoiding the situation where the filtration speed of the filter screen 23 is slow due to the accumulation of solid particles when separating the solid-liquid mixture, thereby further improving the rate of solid-liquid separation.

[0087] As a specific embodiment of the present invention, the number of the filter screens 23 is more than one, and the holes on the filter screens 23 are staggered; and the diameters of the holes on the filter screens 23 decrease in sequence;

[0088] The refined oil flows from the oil outlet pipe 21 to the filter box 19. The solid-liquid mixture is filtered through a plurality of filter screens 23 arranged in sequence from top to bottom. The filter screens 23 are fixed and arranged in sequence from top to bottom. The pore size of each filter screen 23 decreases from top to bottom, which increases the solid particle filtration efficiency and prevents solid particles from accumulating on independent filter screens 23, which may cause difficulty in oil discharge.

[0089] At the same time, the staggered hole design on the filter screen 23 increases the contact area and time between the solid particles in the oil and the filter screen 23, making the refined oil more fully filtered, thereby improving the quality of the finished product of the oil refinery.

[0090] As a specific embodiment of the present invention, a spring 26 is fixed between the filter screens 23;

[0091] The filter screen 23 is fixedly connected to the filter box 19. When too much refined solid-liquid mixture falls onto the filter screen 23, the filter screen 23 will be affected by the gravity of the solid-liquid mixture, which may cause the filter screen 23 to deform and stack together, affecting the filtering effect of the filter screen 23. Therefore, a spring 26 is fixedly connected between each layer of the filter screen 23 to provide an additional support point between each layer of the filter screen 23, thereby avoiding the deformation of the filter screen 23 due to the gravity of excessive oil during the filtration process of the filter screen 23, thereby extending the service life of the filter screen 23 and ensuring the filtering effect of the filter screen 23.

[0092] When the oil contacts the filter 23, the springs 26 between each layer of the filter 23 also buffer the gravity of the oil. When the springs 26 buffer, the filter 23 is caused to vibrate. During the shaking process of the filter 23, the flow rate of the oil on the filter 23 is accelerated, thereby accelerating the filtration speed of the filter 23. At the same time, the vibrating filter 23 also prevents solid particles in the oil from clogging the holes, thereby improving the practicality of the filter 23.

[0093] As a specific embodiment of the present invention, a rubber block 27 is fixedly connected to one side of the No. 1 clamp 16 and the No. 2 clamp 17 close to the screw rod 6. The rubber block 27 is made of nitrile rubber.

[0094] When the No. 1 clamp 16 and the No. 2 clamp 17 clamp the screw rod 6, and the No. 1 forward and reverse motor 2 drives the scraper 7 to rotate, the No. 1 clamp 16 and the No. 2 clamp 17 do not clamp the surface of the screw rod 6 tightly due to the swing of the screw rod 6 and the scraper 7, causing the No. 1 clamp 16 and the No. 2 clamp 17 to move along the surface of the screw rod 6. Therefore, a rubber block 27 is fixedly connected to the side of the clamp close to the screw rod 6 to increase the friction between the No. 1 clamp 16, the No. 2 clamp 17 and the screw rod 6, thereby preventing the No. 1 clamp 16 and the No. 2 clamp 17 from moving along the surface of the screw rod 6, thereby ensuring the normal operation of the equipment.

[0095] During the oil refining process, the screw rod 6 will be affected by the heat transfer of the oil refining inside the cylinder 1, causing the temperature of the screw rod 6 to rise. Therefore, the rubber block 27 is made of nitrile rubber, which improves the oil resistance, wear resistance and heat resistance, avoids the rubber block 27 being damaged by the influence of temperature, and avoids the swing of the screw rod 6 and the scraper 7 causing the clamp to be loose, thereby improving the safety of the equipment and further ensuring the normal operation of the equipment facilities.

[0096] As a specific embodiment of the present invention, a monitoring module 28 is fixed to the top of the T-shaped slider 14;

[0097] When the oil is refined, the No. 1 forward and reverse motor 2 drives the scraper 7 to rotate and stir the oil in the cylinder 1; after stirring is completed, the T-shaped groove 13 on the scraper 7 cannot be aligned with the groove 9 on the inner wall of the cylinder 1. At this time, the monitoring module 28 connected to the external power supply monitors the position of the groove 9 on the inner wall of the cylinder 1, and the induction detector collects the signal, generates a pulse signal, and transmits it to the No. 1 forward and reverse motor 2 controller, thereby causing the No. 1 forward and reverse motor 2 to start the No. 1 forward and reverse motor 2 according to the information of the transmitted groove 9, adjust the position of the scraper 7, and align the T-shaped groove 13 with the groove 9, avoiding the situation that the T-shaped slider 14 cannot enter the groove 9 and slide with it when scraping the inner wall of the cylinder 1, resulting in the scraping assembly being unable to scrape the inner wall of the cylinder 1, further improving the accuracy of whether the T-shaped groove 13 and the groove 9 are aligned, ensuring that the T-shaped slider 14 enters the groove 9, and thus improving the cleaning effect of the scraping assembly on the inner wall of the cylinder 1.

[0098] As a specific embodiment of the present invention, the end of the screw rod 6 away from the first forward and reverse motor 2 is fixedly connected to a push plate 29;

[0099] Driven by the forward rotation of the No. 1 forward and reverse motor 2, the scraper assembly moves downward, and the scraper 7 squeezes the oil in the cylinder 1. The squeezed oil flows out of the oil outlet pipe 21 into the filter box 19, thereby accelerating the rate of oil circulation. In addition, during the downward movement of the scraper assembly, the forward rotation of the No. 1 forward and reverse motor 2 drives the screw rod 6 to rotate. The rotating screw rod 6 drives the fixedly connected push plate 29 to rotate. The rotating push plate 29 pushes the oil at the bottom of the cylinder to the oil outlet, further accelerating the rate at which the oil is pushed out of the cylinder 1, shortening the oil refining time, and improving the efficiency of the oil refining product.

[0100] In addition, during the oil refining process, the forward rotating No. 1 forward and reverse motor 2 also drives the screw 6 to rotate, and the rotating screw 6 drives the push plate 29 to rotate, stirring the oil in the cylinder 1, so that the oil in the cylinder 1 is in full contact with the bottom of the cylinder 1, the oil is heated evenly, and the oil refining speed is accelerated; further improving the overall speed of the oil refining equipment.

[0101] The specific workflow is as follows:

[0102] When it is necessary to refine the oil, the staff opens the oil inlet pipe 4 to fill the inside with oil, and turns on the electric heating wire 3 while injecting the oil to heat and refine the oil in the cylinder 1; at this time, under the control of the electrical system, the No. 1 forward and reverse motor 2 is controlled to rotate forward, and the forward-rotating No. 1 forward and reverse motor drives the screw rod 6 to rotate, and then the screw rod 6 drives the scraper 7 to rotate. Since the T-shaped slider 14 on the top of the scraper 7 is in a locked state with the groove 9 on the inner wall of the cylinder 1, the T-shaped slider 14 limits the rotation of the scraper 7, prompting the scraper 7 to move upward along the direction of the groove 9 provided on the cylinder 1 along the screw rod 6. At the same time, during the rising process of the scraper 7, a cavity is formed between the scraper 7 and the bottom of the cylinder 1, generating negative pressure, which sucks the oil from the oil inlet pipe 4 into the cylinder 1, thereby accelerating the speed of oil injection;

[0103] When the scraper 7 rises along the groove 9 to the top of the groove 9, the rotation of the No. 1 forward and reverse motor 2 is stopped, the oil inlet pipe 4 is closed, and the oil filling is stopped. At this time, the staff operates the electrical system to control the No. 2 forward and reverse motor 11 to rotate forward, and the forward rotating No. 2 forward and reverse motor 11 drives the flat gear 12 to rotate. The rotating flat gear 12 drives the meshing rack 15 to move, and then drives the T-shaped slider 14 fixed on the rack 15 to move laterally along the T-shaped slide 13. In the process of movement, the No. 2 clamp 17 fixedly connected to the T-shaped slider 14 gradually approaches the screw rod 6. When the No. 2 clamp 17 contacts the No. 1 clamp 16, the No. 1 clamp 16 and the No. 2 clamp 17 are tightened to the screw rod 6, thereby fixing the scraper 7 on the screw rod 6, so that the T-shaped slider 14 and the groove 9 are released from the position limit;

[0104] After the fastening assembly fastens the scraper 7 to the screw rod 6, the staff operates the electrical system to control the No. 1 forward and reverse motor to rotate forward. The forward rotating No. 1 forward and reverse motor drives the screw rod 6 to rotate. The rotating screw rod 6 drives the scraper to rotate, and the telescopic rod 18 in the scraper 7 away from the oil liquid surface will be extended to the liquid surface under the action of gravity. At this time, the rotating scraper 7 drives the telescopic rod 18 extending from the scraper 7 to rotate. The rotating telescopic rod 18 stirs the oil in the cylinder 1, so that the oil at the bottom of the cylinder 1 is fully in contact with the oil on the surface of the cylinder 1. At the same time, the rotating screw rod 6 drives the push plate 29 to rotate, stirring the oil in the cylinder 1, so that the oil in the cylinder 1 is fully in contact with the bottom of the cylinder 1, and further makes the oil heated evenly.

[0105] After the oil refining is completed, the monitoring module 28 connected to the external power supply monitors the position of the groove 9 on the inner wall of the cylinder 1, and the induction detector collects the signal, generates a pulse signal, and transmits it to the controller of the No. 1 forward and reverse motor 2, thereby starting the No. 1 forward and reverse motor 2 according to the information of the position of the transmitted groove 9, adjusting the position of the scraper 7, and causing the T-shaped slide 13 to align with the groove 9; at this time, the staff operates the electrical system to control the No. 2 forward and reverse motor 2 to reverse, and the reversed No. 2 forward and reverse motor 11 drives the flat gear 12 to rotate in the opposite direction, and the reverse rotating flat gear 12 drives the meshing rack 15 to move, thereby driving the T-shaped slider 14 fixed to the rack 15 to move laterally along the T-shaped slide 13 to the groove 9, so that the T-shaped slider 14 is engaged with the groove 9, and at the same time, the No. 2 clamp 17 and the No. 1 clamp 16 on the screw rod 6 are released;

[0106] At this time, under the control of the electrical system, the forward and reverse motor 2 is controlled to reverse. Since the T-shaped slider 14 and the groove 9 are in an engaged state, the rotation of the scraper 7 is restricted, prompting the scraper 7 to move downward along the direction of the groove 9 opened on the cylinder 1 along the screw rod 6. In the process of downward movement, the scraper 7, which is in contact with the inner wall of the cylinder 1, scrapes off the solid-liquid mixture adhering to the inner wall of the cylinder 1; thereby, the inner wall of the cylinder 1 is scraped clean; under the action of the engagement of the T-shaped slider 14 and the groove 9, the solid-liquid mixture on the groove 9 is scraped off; the ball 8 between the scraper 7 and the screw rod 6 removes the solid-liquid mixture on the surface of the screw rod 6 during the downward movement, and the downward moving scraper 7 also squeezes the solid-liquid mixture in the cylinder 1, thereby accelerating the discharge speed of the solid-liquid mixture from the cylinder 1, and repeating the above operation when it is necessary to refine the oil again;

[0107] During the downward movement of the scraper 7, due to the restriction of the bottom of the cylinder 1, the scraper 7 moves downward along the screw 6, gradually compressing the solid-liquid mixture in the cylinder 1, and the telescopic rod 18 extending from the scraper 7 first contacts the bottom of the cylinder 1. As the scraper 7 gradually moves downward and contacts the bottom of the cylinder 1, the telescopic rod 18 gradually shrinks. When the solid-liquid mixture in the cylinder 1 is discharged, the scraper 7 reaches the bottom end of the groove 9, and the telescopic rod 18 on the scraper 7 also retracts into the scraper 7; the telescopic rod 18 here does not affect the scraping of the remaining solid mixture on the inner wall of the cylinder 1 by the scraper 7; when the inside of the cylinder 1 is filled with oil, the scraper 7 moves upward again along the screw 6, and at this time the telescopic rod 18 in the scraper 7 retracts downward under the action of its own gravity, and the cycle repeats.

[0108] When the oil refining in the cylinder 1 is completed, the staff will open the baffle 22 on the oil outlet pipe 21, and the solid-liquid mixture in the cylinder 1 will drive the fixedly connected push plate 29 to rotate under its own gravity and the rotating screw 6. The rotating push plate 29 pushes the oil at the bottom of the cylinder to the oil outlet, further accelerating the rate at which the oil is pushed out of the cylinder 1, so that the solid-liquid mixture is discharged from the oil outlet pipe 21 to the filter screen 23 in the filter box 19. At this time, the liquid in the solid-liquid mixture falling on the filter screen 23 flows along the holes on the filter screen 23 to the bottom of the filter box 19, while the solid particles in the solid-liquid mixture are blocked by the filter screen 23 on the surface of the filter screen 23, thereby achieving the effect of solid-liquid separation; a spring 26 is fixedly connected between each layer of the filter screen 23 to provide an additional support point between each layer of the filter screen 23, thereby avoiding the deformation of the filter screen 23 due to the gravity of excessive oil during the filtration process of the filter screen 23;

[0109] When the solid-liquid mixture is separated, the staff opens the drain port 25 to allow the liquid at the bottom of the filter box 19 to flow out from the drain port 25, thereby obtaining the liquid separated after refining. The solid particles remaining on the surface of the filter screen 23 after separation need to be cleaned by the staff by opening the slag discharge port 24 and using special tools to clean the solid particles accumulated on the surface of the filter screen 23, thereby improving the cleanliness of the surface of the filter screen 23 and avoiding the situation where the filtration speed of the filter screen 23 is slow due to the accumulation of solid particles when separating the solid-liquid mixture, thereby further improving the rate of solid-liquid separation.
