Description

Technical Field

[0001] The invention relates to the technical field of chemical separation equipment, in particular to a high vacuum pressure reducing tower. Background Art

[0002] A vacuum tower is a device used for distillation and fractionation, commonly used in the petroleum, chemical, pharmaceutical and food industries. It can separate high-boiling-point components from a mixture for subsequent processing and utilization. The working principle of a vacuum tower is to heat the mixture below its boiling point and then separate it in a vacuum tower. Under reduced pressure, the low-boiling-point components in the mixture evaporate first and then condense into liquid in the tower, finally obtaining pure components.

[0003] The plate structure of the vacuum tower includes plates, overflow weirs and downcomers. A certain number of channels are provided on the plates for gas to pass through the liquid layer on the plates from top to bottom, so that the gas and liquid phases are fully in contact. The oil treated by the vacuum distillation tower is heavy and has a high viscosity. When steam passes through the oil layer, it will force too much foam to appear in the oil layer. The internal space of the vacuum tower is small, which makes it difficult for the foam to burst by itself. In view of the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a high vacuum pressure reducing tower, comprising a tower body, a feed pipe is connected through the side wall of the tower body, a steam pipe is connected through the side wall of the tower body, three distillate oil pipes are connected through the side wall of the tower body, a tower bottom pipe is connected through the bottom of the tower body, and a vacuum pipe is connected through the top of the tower body; The reaction mechanism comprises three fixing rings fixedly connected to the inner wall of the tower body, a containing plate is fixedly connected to the inner wall of the fixing ring, and a plurality of exhaust holes are opened on the side wall of the containing plate; The stirring mechanism includes an annular slide groove 1 opened on the top of the fixed ring, a mounting ring box is rotatably connected to the inner wall of the annular slide groove 1, a plurality of inclined fan blades are fixedly connected to the inner wall of the mounting ring box, an annular slide groove 2 is opened on the top of the mounting ring box, a cleaning component is slidably connected to the outer wall of the inclined fan blade, and a control component is rotatably connected to the inner wall of the mounting ring box. Before use, the tower body is installed in the required position and all pipelines on the outer wall of the tower body are connected, and then a decompression separation process is performed. During this process, high-pressure gas enters the tower body from the steam pipe and moves upward along the inner wall of the tower body during the extraction of the vacuum pipe. At this time, the upwardly moving gas contacts the oil on the top of the holding plate through the exhaust hole. During this process, the upwardly moving high-pressure gas will act on the bottom slope of the inclined fan blade, forcing multiple inclined fan blades to drive the mounting ring box to rotate along the inner wall of the annular slide groove 1, and while the mounting ring box rotates, multiple inclined fan blades will perform a stirring process inside the oil to remove most of the bubbles when the steam reacts with the oil.

[0005] Preferably, the cleaning component includes a sliding scraper slidably connected to the outer wall of the inclined fan blade, a rotating plate is rotatably connected to the outer wall of the sliding scraper, and two fixed brackets are fixedly connected to the side walls of the inclined fan blade. When high-pressure gas acts on the bottom slope of the inclined fan blade, part of the gas will penetrate into the oil on the top of the containing plate again, increasing the contact area between the steam and the oil and improving the reaction rate. Through the application of the above-mentioned components, the reaction rate of the equipment can be improved while effectively removing bubbles.

[0006] Preferably, the cleaning assembly also includes a rolling column rotatably connected to the inner wall of the fixed bracket, two spring telescopic rods are fixedly connected to the inner wall of the inclined fan blade, and a fixed hook rod is fixedly connected to the inner wall of the rotating plate.

[0007] Preferably, the cleaning component also includes a fixed bracket 2 fixedly connected to the side wall of the sliding scraper, the inner wall of the fixed bracket 2 is rotatably connected with a rotating hook rod, and the side wall of the rotating hook rod is provided with an inclined surface. By utilizing the characteristic of the inclined fan blade stirring inside the oil, a cleaning component is arranged inside the equipment. When high-pressure steam starts from the exhaust hole and forces the inclined fan blade to rotate counterclockwise, the oil will move along the inclined surface of the inclined fan blade. In this process, Figure 5 As shown, the counterclockwise rotating inclined blade will drive the rotating plate to contact with the oil, and the rotating plate will generate a force to move horizontally to the right, and the rotating plate drives the sliding scraper to slide along the outer wall of the inclined blade to achieve scraping and cleaning of the outer wall of the inclined blade, and as the sliding scraper moves horizontally to the right, the rotating plate will contact the outer wall of the spring telescopic rod 1, and force the spring telescopic rod 1 to contract and accumulate mechanical power; as the sliding scraper moves horizontally, the outer wall of the rolling column will contact the outer wall of the rotating hook rod, and the rolling column will force the rotating hook rod to rotate downward at one end close to the spring 1, and the other end of the rotating hook rod One end will tilt upward with fixed bracket 2 as the fulcrum, so that the protruding block of the rotating hook rod will move away from the fixed hook rod and the restriction of the fixed hook rod will be released. At this time, the spring telescopic rod 1 will release mechanical power, forcing the rotating plate to swing with the connection point as the center of gravity, and the rotating plate will drive another fixed hook rod to contact another rotating hook rod, completing the restriction of the rotating plate. When the rotating plate with the angle change comes into contact with the oil again, it will force the rotating plate to move horizontally again, so that the rotating plate can move back and forth along the outer wall of the inclined fan blade through the application of the above-mentioned components, and the sliding scraper can continuously scrape and clean the outer wall of the inclined fan blade.

[0008] Preferably, the cleaning assembly includes a spring 1 fixedly connected to the end of the rotating hook rod away from the inclined surface, the end of the spring 1 away from the rotating hook rod is fixedly connected to the side wall of the sliding scraper, and a scratching assembly is fixedly connected to the side wall of the rotating plate.

[0009] Preferably, the scraping assembly includes a sliding groove provided on the side wall of the rotating plate, a spring telescopic rod 2 is fixedly connected to the inner wall of the sliding groove, the other end of the spring telescopic rod 2 is fixedly connected to an arc scraper, the outer wall of the arc scraper is slidably connected to the inner wall of the sliding groove, and a scraping assembly is arranged inside the device by utilizing the swinging characteristic of the rotating plate. When the rotating plate swings, the contact surface between the rotating plate and the oil will change. When the rotating plate does not change its angle, such as Figure 7 As shown in the middle rotating plate, at this time, the rotating plate is in direct contact with the oil, forcing the oil to flow along this surface. At this time, the flowing oil will push the arc scraper to slide along the inner wall of the sliding groove, forcing the spring telescopic rod 2 to accumulate mechanical power.

[0010] Preferably, the control component includes a gear rod fixedly connected to the side wall of the sliding scraper, a circular ring is slidably connected to the inner wall of the annular slide groove 2, and an arc-shaped gear rod is fixedly connected to the side wall of the circular ring. After the rotating plate completes the stirring transformation, the circular contact surface of the rotating plate flips and is on the back of the rotating plate. At this time, the compressed spring telescopic rod 2 will release mechanical power to reset the arc-shaped scraper along the inner wall of the sliding groove. At the same time, the arc-shaped scraper scratches and cleans the outer wall of the rotating plate. Through the application of the above-mentioned components, excessive oil residue on the outer wall of the rotating plate can be avoided, which will dry out under the influence of high temperature of steam and affect the turning speed of the rotating plate.

[0011] Preferably, the control component also includes a gear 2 which is rotatably connected to the inner wall of the mounting ring box, the outer wall of the gear 2 is meshingly connected to the outer wall of the arcuate gear rod, the top of the gear 2 is fixedly connected with a gear column, the outer wall of the gear column is meshingly connected to the outer wall of the gear rod, and utilizing the characteristic of the above-mentioned sliding scraper moving laterally along the outer wall of the inclined fan blade, a control component is arranged inside the equipment, when multiple sliding scrapers move laterally, the sliding scrapers drive the gear column to rotate through the gear rod, and the gear column drives the circular ring to slide along the inner wall of the annular slide groove 2 through gear 2 and the arcuate gear rod, and the rotation of the circular ring in this process will drive multiple gear 2s to rotate synchronously, so when the sliding scraper moves laterally left and right, the circular ring will rotate, and through the application of the above-mentioned components, a large piece of adhesive is adhered to the outer wall of one of the rotating plates When the oil is thick, the corresponding sliding scraper will be blocked and unable to move. At this time, when a single sliding scraper cannot move outward, the gear rod will limit the rotation of the corresponding gear column and gear 2, thereby limiting the rotation of the ring. The ring stops rotating, and the remaining sliding scrapers will also be blocked and unable to move, ensuring that the speed and length of movement of multiple sliding scrapers are controlled during operation, avoiding the different positions of multiple sliding scrapers, which causes the rotation center of gravity of the inclined fan blade to change, affecting the defoaming efficiency of the equipment; in addition, when a single sliding scraper is blocked, the remaining rotating plates still generate an outward thrust, and the thrust is transmitted to the restricted sliding scraper position through the ring, so that the restricted sliding scraper generates greater pressure to scrape off large viscous blocks stuck to the outer wall of the inclined fan blade.

[0012] The present invention has the following beneficial effects: (1) The present invention utilizes the characteristic that the high-pressure gas in the vacuum tower flows from bottom to top, and a reaction mechanism and a stirring mechanism are arranged inside the equipment. Before use, the tower body is installed at the desired position and all the pipes on the outer wall of the tower body are connected, and then the process of decompression and separation is carried out. In this process, the high-pressure gas enters the tower body from the steam pipe and moves upward along the inner wall of the tower body during the extraction of the vacuum tube. At this time, the upward-moving gas contacts the oil on the top of the holding plate through the exhaust hole. In this process, the upward-moving high-pressure gas will act on the bottom slope of the inclined fan blade, forcing the multiple inclined fan blades to drive the mounting ring box to rotate along the inner wall of the annular slide groove. While the mounting ring box rotates, the multiple inclined fan blades will stir the inside of the oil to remove most of the bubbles when the steam reacts with the oil. In addition, when the high-pressure gas acts on the bottom slope of the inclined fan blade, part of the gas will penetrate into the oil on the top of the holding plate again, increasing the contact area between the steam and the oil and improving the reaction rate. Through the application of the above components, the reaction rate of the equipment can be improved while effectively removing bubbles.

[0013] (2) The present invention utilizes the characteristic of the inclined blades stirring the oil inside, and a cleaning component is arranged inside the equipment. When the high-pressure steam starts from the exhaust hole and forces the inclined blades to rotate counterclockwise, the oil will move along the inclined surface of the inclined blades. In this process, Figure 5 As shown, the counterclockwise rotating inclined blade will drive the rotating plate to contact with the oil, and the rotating plate will generate a force to move horizontally to the right, and the rotating plate drives the sliding scraper to slide along the outer wall of the inclined blade to achieve scraping and cleaning of the outer wall of the inclined blade, and as the sliding scraper moves horizontally to the right, the rotating plate will contact the outer wall of the spring telescopic rod 1, and force the spring telescopic rod 1 to contract and accumulate mechanical power; as the sliding scraper moves horizontally, the outer wall of the rolling column will contact the outer wall of the rotating hook rod, and the rolling column will force the rotating hook rod to rotate downward at one end close to the spring 1, and the other end of the rotating hook rod One end will tilt upward with fixed bracket 2 as the fulcrum, so that the protruding block of the rotating hook rod will move away from the fixed hook rod and the restriction of the fixed hook rod will be released. At this time, the spring telescopic rod 1 will release mechanical power, forcing the rotating plate to swing with the connection point as the center of gravity, and the rotating plate will drive another fixed hook rod to contact another rotating hook rod, completing the restriction of the rotating plate. When the rotating plate with the angle change is in contact with the oil again, it will force the rotating plate to move horizontally again, realizing the reciprocating movement of the rotating plate along the outer wall of the inclined fan blade. Through the application of the above components, the sliding scraper can continuously scrape and clean the outer wall of the inclined fan blade.

[0014] (3) The present invention utilizes the swinging characteristic of the rotating plate and provides a scratching assembly inside the device. When the rotating plate swings, the contact surface between the rotating plate and the oil will change. When the rotating plate does not change its angle, Figure 7As shown in the rotating plate in the figure, at this time, the rotating plate is in direct contact with the oil, forcing the oil to flow along this surface, and the flowing oil at this time will push the arc scraper to slide along the inner wall of the sliding groove, forcing the spring telescopic rod 2 to accumulate mechanical power; after the rotating plate completes the stirring transformation, the circular contact surface of the rotating plate flips over and is on the back of the rotating plate. At this time, the compressed spring telescopic rod 2 will release the mechanical power, causing the arc scraper to reset along the inner wall of the sliding groove, and at the same time, the arc scraper scratches and cleans the outer wall of the rotating plate. Through the application of the above components, it is possible to avoid excessive oil residue on the outer wall of the rotating plate, which will dry out under the influence of high temperature of steam and affect the turning speed of the rotating plate.

[0015] (4) The present invention utilizes the characteristic that the above-mentioned sliding scraper moves laterally along the outer wall of the inclined fan blade, and a control component is arranged inside the device. When multiple sliding scrapers move laterally, the sliding scraper drives the tooth column to rotate through the tooth rod, and the tooth column drives the circular ring to slide along the inner wall of the annular slide groove 2 through the gear 2 and the arc-shaped gear rod. In this process, the rotation of the circular ring will drive multiple gears 2 to rotate synchronously. Therefore, when the sliding scraper moves laterally to the left or right, the circular ring will rotate. Through the application of the above-mentioned components, when a large piece of viscous oil is stuck to the outer wall of one of the rotating plates, the corresponding sliding scraper will be blocked and unable to move. At this time, when a single sliding scraper cannot move laterally outward , the gear rod will limit the rotation of the corresponding gear column and gear 2, thereby limiting the rotation of the ring. The ring stops rotating, and the remaining sliding scrapers will also be blocked and unable to move, ensuring that the speed and length of movement of multiple sliding scrapers are controlled during operation, avoiding the different positions of multiple sliding scrapers, causing the rotation center of gravity of the inclined fan blade to change, affecting the defoaming efficiency of the equipment; in addition, when a single sliding scraper is blocked, the remaining rotating plates still generate an outward thrust, and the thrust is transmitted to the restricted sliding scraper position through the ring, so that the restricted sliding scraper generates greater pressure and scrapes off the large viscous blocks stuck to the outer wall of the inclined fan blade.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figure 1 - Figure 4 The present invention is a high vacuum pressure reducing tower, comprising a tower body 1, a feed pipe 11 is connected through the side wall of the tower body 1, a steam pipe 12 is connected through the side wall of the tower body 1, three distillate oil pipes 13 are connected through the side wall of the tower body 1, a tower bottom pipe 14 is connected through the bottom of the tower body 1, and a vacuum pipe 15 is connected through the top of the tower body 1; The reaction mechanism 2 includes three fixing rings 21 fixedly connected to the inner wall of the tower body 1, a containing plate 22 is fixedly connected to the inner wall of the fixing ring 21, and a plurality of exhaust holes 23 are opened on the side wall of the containing plate 22; The stirring mechanism 3 includes an annular chute 1 31 provided on the top of the fixed ring 21, a mounting ring box 32 is rotatably connected to the inner wall of the annular chute 1 31, a plurality of inclined blades 33 are fixedly connected to the inner wall of the mounting ring box 32, an annular chute 2 34 is provided on the top of the mounting ring box 32, a cleaning component 4 is slidably connected to the outer wall of the inclined blade 33, and a control component 6 is rotatably connected to the inner wall of the mounting ring box 32. Before use, the tower body 1 is installed at the desired position and all pipelines on the outer wall of the tower body 1 are connected, and then a decompression separation process is performed. In this process, The high-pressure gas enters the tower body 1 from the steam pipe 12 and moves upward along the inner wall of the tower body 1 during the extraction of the vacuum tube 15. At this time, the upward-moving gas makes two-phase contact with the oil on the top of the holding plate 22 through the exhaust hole 23. In this process, the upward-moving high-pressure gas will act on the bottom slope of the inclined blades 33, forcing the multiple inclined blades 33 to drive the mounting ring box 32 to rotate along the inner wall of the annular slide groove 31. While the mounting ring box 32 rotates, the multiple inclined blades 33 will stir the oil inside to remove most of the bubbles when the steam reacts with the oil.

[0021] For example 2, please refer to Figure 5 - Fig.10 The present invention is a high vacuum pressure reducing tower. On the basis of the first embodiment, the cleaning component 4 includes a sliding scraper 41 slidably connected to the outer wall of the inclined fan blade 33, and a rotating plate 42 is rotatably connected to the outer wall of the sliding scraper 41. Two fixed brackets 43 are fixedly connected to the side walls of the inclined fan blade 33. When the high-pressure gas acts on the bottom inclined surface of the inclined fan blade 33, part of the gas will penetrate into the oil on the top of the holding plate 22 again, thereby increasing the contact area between the steam and the oil and improving the reaction rate. Through the application of the above components, the reaction rate of the equipment can be improved while effectively removing bubbles.

[0022] The cleaning assembly 4 also includes a rolling column 44 rotatably connected to the inner wall of the fixed bracket 43, two spring telescopic rods 45 are fixedly connected to the inner wall of the inclined fan blade 33, and a fixed hook rod 46 is fixedly connected to the inner wall of the rotating plate 42.

[0023] The cleaning assembly 4 also includes a fixed bracket 47 fixedly connected to the side wall of the sliding scraper 41, and a rotating hook rod 48 is rotatably connected to the inner wall of the fixed bracket 47. An inclined surface 49 is provided on the side wall of the rotating hook rod 48. The cleaning assembly 4 is arranged inside the equipment by utilizing the stirring characteristics of the inclined blade 33 in the oil. When the high-pressure steam starts from the exhaust hole 23 and forces the inclined blade 33 to rotate counterclockwise, the oil will move along the inclined surface of the inclined blade 33. In this process, Figure 5 As shown, the counterclockwise rotating inclined blade 33 will drive the rotating plate 42 to contact with the oil, and the rotating plate 42 will generate a force to move horizontally to the right, and the rotating plate 42 drives the sliding scraper 41 to slide along the outer wall of the inclined blade 33 to achieve the scraping and cleaning of the outer wall of the inclined blade 33, and as the sliding scraper 41 moves horizontally to the right, the rotating plate 42 will contact the outer wall of the spring telescopic rod 45, and force the spring telescopic rod 45 to contract and accumulate mechanical power; as the sliding scraper 41 moves horizontally, the outer wall of the rolling column 44 will contact the outer wall of the rotating hook rod 48, and the rolling column 44 will force the rotating hook rod 48 to rotate downward near the end of the spring 410, and the rotating hook rod 4 The other end will tilt upward with the fixed bracket 47 as the fulcrum, so that the protruding block of the rotating hook rod 48 will be away from the fixed hook rod 46 and the restriction of the fixed hook rod 46 will be released. At this time, the spring telescopic rod 45 will release the mechanical power, forcing the rotating plate 42 to swing with the connection point as the center of gravity, and the rotating plate 42 will drive another fixed hook rod 46 to contact with another rotating hook rod 48, completing the restriction of the rotating plate 42. When the rotating plate 42 with the angle change is in contact with the oil again, it will force the rotating plate 42 to move horizontally again, so that the rotating plate 42 can reciprocate along the outer wall of the inclined fan blade 33. Through the application of the above components, the sliding scraper 41 can continuously scrape and clean the outer wall of the inclined fan blade 33.

[0024] The cleaning assembly 4 includes a spring 410 fixedly connected to the end of the rotating hook rod 48 away from the inclined surface 49. The end of the spring 410 away from the rotating hook rod 48 is fixedly connected to the side wall of the sliding scraper 41. The side wall of the rotating plate 42 is fixedly connected with a scratching assembly 5.

[0025] The scraping assembly 5 includes a sliding groove 51 provided on the side wall of the rotating plate 42, a spring telescopic rod 52 is fixedly connected to the inner wall of the sliding groove 51, and an arc scraper 53 is fixedly connected to the other end of the spring telescopic rod 52. The outer wall of the arc scraper 53 is slidably connected to the inner wall of the sliding groove 51. By utilizing the swinging characteristic of the rotating plate 42, a scraping assembly 5 is arranged inside the device. When the rotating plate 42 swings, the contact surface between the rotating plate 42 and the oil will change. When the rotating plate 42 does not change its angle, as shown in FIG. Figure 7As shown in the middle rotating plate 42, at this time, the rotating plate 42 is in direct contact with the oil, forcing the oil to flow along this surface. At this time, the flowing oil will push the arc scraper 53 to slide along the inner wall of the sliding groove 51, forcing the spring telescopic rod 2 52 to accumulate mechanical power.

[0026] The control component 6 includes a gear rod 61 fixedly connected to the side wall of the sliding scraper 41, a circular ring 62 is slidably connected to the inner wall of the annular slide groove 34, and an arc-shaped gear rod 63 is fixedly connected to the side wall of the circular ring 62. After the rotating plate 42 completes the stirring transformation, the circular contact surface of the rotating plate 42 flips over and is on the back of the rotating plate 42. At this time, the compressed spring telescopic rod 52 will release the mechanical power to reset the arc-shaped scraper 53 along the inner wall of the sliding groove 51. At the same time, the arc-shaped scraper 53 scrapes and cleans the outer wall of the rotating plate 42. Through the application of the above-mentioned components, it is avoided that too much oil remains on the outer wall of the rotating plate 42, and it is dried under the influence of the high temperature of the steam, affecting the turning speed of the rotating plate 42.

[0027] The control component 6 also includes a gear 2 64 rotatably connected to the inner wall of the mounting ring box 32, the outer wall of the gear 2 64 is meshed with the outer wall of the arc-shaped gear rod 63, the top of the gear 2 64 is fixedly connected with a gear column 65, the outer wall of the gear column 65 is meshed with the outer wall of the gear rod 61. By utilizing the characteristic that the above-mentioned sliding scraper 41 moves horizontally along the outer wall of the inclined fan blade 33, a control component 6 is arranged inside the equipment. When multiple sliding scrapers 41 move horizontally, the sliding scraper 41 drives the gear column 65 to rotate through the gear rod 61, and the gear column 65 drives the ring 62 to slide along the inner wall of the annular slide groove 2 34 through the gear 2 64 and the arc-shaped gear rod 63. In this process, the rotation of the ring 62 will drive multiple gears 2 64 to rotate synchronously. Therefore, when the sliding scraper 41 moves horizontally left and right, the ring 62 will rotate. Through the application of the above-mentioned components, on the outer side of one of the rotating plates 42 When a large piece of viscous oil is stuck to the wall, the corresponding sliding scraper 41 will be blocked and unable to move. At this time, when a single sliding scraper 41 cannot move outward, the gear rod 61 will limit the rotation of the corresponding gear column 65 and gear 2 64, thereby limiting the rotation of the ring 62. The ring 62 stops rotating, and the remaining sliding scrapers 41 will also be blocked and unable to move, ensuring that the speed and length of movement of multiple sliding scrapers 41 are controlled during operation, avoiding the different positions of multiple sliding scrapers 41, causing the rotation center of gravity of the inclined fan blade 33 to change, affecting the defoaming efficiency of the equipment; in addition, when a single sliding scraper 41 is blocked, the remaining rotating plates 42 still generate an outward thrust, and the thrust is transmitted to the restricted position of the sliding scraper 41 through the ring 62, so that the restricted sliding scraper 41 generates greater pressure to scrape off the large viscous blocks stuck to the outer wall of the inclined fan blade 33.

[0028] A specific application of this embodiment is: before use, the tower body 1 is installed at the desired position, and all the pipelines on the outer wall of the tower body 1 are connected, and then a decompression separation process is performed. In this process, high-pressure gas enters the interior of the tower body 1 from the steam pipe 12, and moves upward along the inner wall of the tower body 1 during the extraction of the vacuum tube 15. At this time, the upwardly moving gas is in two-phase contact with the oil on the top of the holding plate 22 through the exhaust hole 23. In this process, the upwardly moving high-pressure gas will act on the bottom slope of the inclined blade 33, forcing the multiple inclined blades 33 to drive the mounting ring box 32 to rotate along the inner wall of the annular slide groove 31, and while the mounting ring box 32 rotates, the multiple inclined blades 33 will perform a stirring process inside the oil to remove most of the bubbles when the steam reacts with the oil; in addition, when the high-pressure gas acts on the bottom slope of the inclined blade 33, part of the gas will penetrate into the oil on the top of the holding plate 22 again, increasing the contact area between the steam and the oil, and increasing the reaction rate. Through the application of the above components, the reaction rate of the equipment can be improved while effectively removing bubbles.

[0029] Taking advantage of the stirring characteristics of the inclined blades 33 in the oil, a cleaning component 4 is arranged inside the equipment. When the high-pressure steam starts from the exhaust hole 23 and forces the inclined blades 33 to rotate counterclockwise, the oil will move along the inclined surface of the inclined blades 33. In this process, Figure 5 As shown, the counterclockwise rotating inclined blade 33 will drive the rotating plate 42 to contact with the oil, and the rotating plate 42 will generate a force to move horizontally to the right, and the rotating plate 42 drives the sliding scraper 41 to slide along the outer wall of the inclined blade 33 to achieve the scraping and cleaning of the outer wall of the inclined blade 33, and as the sliding scraper 41 moves horizontally to the right, the rotating plate 42 will contact the outer wall of the spring telescopic rod 45, and force the spring telescopic rod 45 to contract and accumulate mechanical power; as the sliding scraper 41 moves horizontally, the outer wall of the rolling column 44 will contact the outer wall of the rotating hook rod 48, and the rolling column 44 will force the rotating hook rod 48 to rotate downward near the end of the spring 410, and the rotating hook rod 4 The other end will tilt upward with the fixed bracket 47 as the fulcrum, so that the protruding block of the rotating hook rod 48 will be away from the fixed hook rod 46 and the restriction of the fixed hook rod 46 will be released. At this time, the spring telescopic rod 45 will release the mechanical power, forcing the rotating plate 42 to swing with the connection point as the center of gravity, and the rotating plate 42 will drive another fixed hook rod 46 to contact with another rotating hook rod 48, completing the restriction of the rotating plate 42. When the rotating plate 42 with the angle change is in contact with the oil again, it will force the rotating plate 42 to move horizontally again, so that the rotating plate 42 can reciprocate along the outer wall of the inclined fan blade 33. Through the application of the above components, the sliding scraper 41 can continuously scrape and clean the outer wall of the inclined fan blade 33.

[0030] Taking advantage of the swinging characteristic of the rotating plate 42, a scratching assembly 5 is provided inside the device. When the rotating plate 42 swings, the contact surface between the rotating plate 42 and the oil will change. When the rotating plate 42 does not change its angle, Figure 7 As shown in the middle rotating plate 42, at this time, the rotating plate 42 is in direct contact with the oil, forcing the oil to flow along this surface, and the flowing oil at this time will push the arc scraper 53 to slide along the inner wall of the sliding groove 51, forcing the spring telescopic rod 2 52 to accumulate mechanical power; and after the rotating plate 42 completes the stirring transformation, the circular contact surface of the rotating plate 42 is turned over and is on the back of the rotating plate 42. At this time, the compressed spring telescopic rod 2 52 will release the mechanical power, so that the arc scraper 53 is reset along the inner wall of the sliding groove 51, and at the same time, the arc scraper 53 scratches and cleans the outer wall of the rotating plate 42. Through the application of the above-mentioned components, it is avoided that too much oil remains on the outer wall of the rotating plate 42, and it is dried under the influence of the high temperature of the steam, affecting the turning speed of the rotating plate 42.

[0031] Taking advantage of the characteristic that the sliding scraper 41 moves laterally along the outer wall of the inclined fan blade 33, a control component 6 is provided inside the device. When multiple sliding scrapers 41 move laterally, the sliding scraper 41 drives the tooth column 65 to rotate through the toothed rod 61, and the toothed rod 65 drives the ring 62 to slide along the inner wall of the annular slide groove 2 34 through the gear 2 64 and the arc geared rod 63. In this process, the rotation of the ring 62 will drive multiple gears 2 64 to rotate synchronously. Therefore, when the sliding scraper 41 moves laterally left and right, the ring 62 will rotate. Through the application of the above-mentioned components, when a large piece of viscous oil is stuck to the outer wall of one of the rotating plates 42, the corresponding sliding scraper 41 will be blocked and unable to move. At this time, a single sliding scraper 41 cannot move laterally outward. , the gear rod 61 will limit the rotation of the corresponding gear column 65 and gear 2 64, thereby limiting the rotation of the ring 62. The ring 62 stops rotating, and the remaining sliding scrapers 41 will also be blocked and unable to move, ensuring that the speed and length of movement of multiple sliding scrapers 41 are controlled during operation, avoiding the different positions of multiple sliding scrapers 41, which causes the rotation center of gravity of the inclined fan blade 33 to change, affecting the defoaming efficiency of the equipment; in addition, when a single sliding scraper 41 is blocked, the remaining rotating plates 42 still generate an outward thrust, and the thrust is transmitted to the restricted position of the sliding scraper 41 through the ring 62, so that the restricted sliding scraper 41 generates greater pressure, scraping off large viscous blocks stuck to the outer wall of the inclined fan blade 33.
