Description

Technical Field

[0001] The present invention relates to the technical field of gas-liquid separators, and specifically discloses a vortex fan swirl high-efficiency and energy-saving gas separator. Background Art

[0002] In industries such as oil and gas, chemical engineering, environmental protection, and air separation, the separation of gas and liquid is an important process. There are various separation methods used in gas-liquid separators, including gravity sedimentation, baffle separation, centrifugal separation, wire mesh separation, ultrafiltration separation, and packing separation, etc. Among them, centrifugal separation is widely used in high-precision separation scenarios such as oil and chemical industries due to its advantages of high efficiency, compact structure, and ability to handle small liquid droplets.

[0003] For example, the patent with the publication number CN118649476A, and the publication date is September 17, 2024. It discloses a gas-liquid separator and a gas-liquid separation method, including a mounting frame and a separation tank fixedly installed on the mounting frame. An centrifugal barrel is arranged inside the separation tank. It also includes an inlet pipe arranged on the separation tank. The inlet pipe is communicated with the inside of the centrifugal barrel and enters tangentially along the centrifugal barrel. A blocking unit is arranged inside the centrifugal barrel. In the present invention, because the centrifugal forces received by the liquid and the gas are different, the liquid has a tendency of centrifugal separation. The liquid rotates in a spiral motion along the inside of the centrifugal barrel. When the liquid flows, it collides with the inside of the centrifugal barrel and is easily fragmented, generating finer liquid droplets that flow away from the inner wall of the centrifugal barrel. Under the action of the blocking unit, the rebounding liquid passes through the edge of the centrifugal barrel and is collected, thus preventing the liquid droplets from returning to the gas phase again, so as to improve the gas-liquid separation efficiency.

[0004] For example, the patent with the publication number CN118437040A, and the publication date is August 6, 2024. It discloses a gas-liquid separator for improving gas-liquid separation efficiency, including a condenser assembly, a wire mesh demister, a liquid seal assembly, and a fiber filter assembly integrally integrated inside the gas-liquid separation tank. The lower part of the fiber filter assembly is communicated with the liquid seal assembly. By using the gas-liquid separator of the present invention, the separated liquid phase is condensed and cooled, the separated gas phase is purified, and the liquid phase is filtered. At the same time, the setting of the liquid seal assembly further separates and exports the liquid phase and the gas phase separated by the fiber filter assembly. Through the liquid seal mechanism, it prevents the separated gas phase from entering the lower gas-liquid separation chamber again, and prevents the liquid phase filtered by the fiber filter assembly from remaining in the fiber filter assembly too much, affecting the separation effect of the fiber filter assembly, and finally achieving the purpose of improving the gas-liquid separation efficiency.

[0005] The deficiencies of existing gas-liquid separators including the above patents are as follows: the former passes the gas-liquid mixture into the centrifugal barrel along the tangential direction, enabling the mixture to perform a spiral rotation motion inside the centrifugal barrel, and separating the gas and liquid by taking advantage of the different centrifugal forces received by the liquid and the gas; while the latter separates the gas phase and the liquid phase by setting up structures such as wire mesh demisters and fiber filter components; the separation efficiency of both for the gas-liquid mixture is very low. Summary of the Invention

[0006] The object of the present invention is to provide a vortex fan swirl high-efficiency and energy-saving gas separator with high separation efficiency and not easily blocked.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A vortex fan swirl high-efficiency and energy-saving gas separator includes a tank body. A feed pipe is arranged on the side of the tank body, an outlet pipe is arranged at the top of the tank body, and a liquid outlet pipe is arranged at the bottom of the tank body. A centrifugal barrel is arranged in the middle of the tank body. The feed pipe is communicated into the centrifugal barrel, and the centrifugal barrel is communicated with the space inside the tank body. A first fan is arranged inside the centrifugal barrel, and the first fan is driven to rotate so as to form a swirl inside the centrifugal barrel.

[0009] In the above gas separator, the centrifugal barrel is horizontally arranged. A plurality of groups of first fans are arranged along the axial direction of the centrifugal barrel inside the centrifugal barrel. A liquid discharge port is opened at the lower part of the centrifugal barrel in the gravity direction, and an exhaust port is also opened at the upper part of the centrifugal barrel in the gravity direction. A rotating shaft is arranged along the circumferential direction of the centrifugal barrel inside the centrifugal barrel, and each first fan is sleeved outside the rotating shaft.

[0010] In the above gas separator, the centrifugal barrel includes a sleeve and a barrel body with both ends closed. The sleeve is sleeved at one end of the centrifugal barrel, and the feed pipe is communicated with the sleeve. An air inlet is opened along the tangential direction of the side wall of the barrel body corresponding to the sleeve.

[0011] In the above gas separator, a screen group is arranged in the upper part of the tank body. The screen group includes a first screen plate, a second screen plate, and a third screen plate which are distributed in sequence from bottom to top. The mesh holes of the first screen plate, the second screen plate, and the third screen plate gradually become smaller.

[0012] In the above gas separator, second fans are respectively arranged on the tank body corresponding to the first screen plate, the second screen plate, and the third screen plate, and each second fan is respectively arranged below the first screen plate, the second screen plate, and the third screen plate.

[0013] In the above gas separator, a scraping component is arranged inside the barrel body, and the scraping component is driven to move along the axial direction of the barrel body to clean the inner wall of the barrel body.

[0014] In the above gas separator, the scraping component includes a scraping ring, the outer diameter of the scraping ring is equal to the inner diameter of the cylinder body, and a driving member for driving the scraping ring to move axially along the cylinder body is arranged on the cylinder body.

[0015] In the above gas separator, the driving member includes a winding roller installed on the outer wall of the cylinder body. The winding roller is rotatably installed outside the cylinder body. A first motor is also installed outside the cylinder body. The first motor drives the winding roller to rotate. A pulling rope is wound around the winding roller. Both ends of the pulling rope penetrate into the inside of the cylinder body from positions near both ends of the side wall of the cylinder body, and both ends of the pulling rope are connected to both end faces of the scraping ring.

[0016] In the above gas separator, the cross section of the scraping ring is in the shape of a right trapezoid, and the inclined surface of the hanging ring faces one end of the cylinder body corresponding to the sleeve.

[0017] In the above gas separator, the scraping component further includes a material receiving ring. The axial dimension of the material receiving ring is larger than that of the scraping ring. The scraping ring is sleeved outside the material receiving ring. The scraping ring is driven to drive the material receiving ring to move axially along the cylinder body, and the scraping ring has a first position and a second position relative to the material receiving ring. A locking member is arranged on the scraping ring, and the locking member is used to lock the scraping ring at the first position or the second position.

[0018] In the above technical solution, in the vortex fan swirl high-efficiency and energy-saving gas separator provided by the present invention, by installing a first fan in the centrifugal cylinder, the rotation of the first fan will cause the introduced mixture to generate a swirl. Through the centrifugal force generated by the rotation, the solid phase (solid particles) with a large density and the liquid phase come into contact with the inner wall of the centrifugal cylinder. At the same time, the solid particles and tiny liquid droplets in the gas collide with the fan blades, which can promote the coalescence of the liquid droplets and form a liquid film on the inner wall of the centrifugal cylinder. Subsequently, under the action of gravity, they flow into the bottom of the separator and are discharged, thereby realizing efficient gas-liquid separation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0031] In the description of the present invention, unless otherwise specified, "a plurality of" means two or more; the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and thus should not be construed as a limitation to the present invention. In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] As Figures 1-8 shown, a kind of vortex fan swirl high-efficiency energy-saving gas separator provided by an embodiment of the present invention includes a tank body 1. A feed pipe 11 is arranged on the side surface of the tank body 1, an air outlet pipe 12 is arranged on the top of the tank body 1, and a liquid outlet pipe 13 is arranged at the bottom of the tank body 1. A centrifugal cylinder 2 is arranged in the middle of the tank body 1. The feed pipe 11 communicates with the inside of the centrifugal cylinder 2. The centrifugal cylinder 2 communicates with the space inside the tank body 1. A first fan 3 is arranged inside the centrifugal cylinder 2. The first fan 3 is driven to rotate so as to form a swirl inside the centrifugal cylinder 2.

[0033] Specifically, this gas separator is used to separate a gas-liquid mixture (hereinafter referred to as the mixture). Its main structure is the tank body 1, as Figure 1As shown in the figure, a feed pipe 11, an air outlet pipe 12 and a liquid outlet pipe 13 are connected to the tank body 1. Among them, the feed pipe 11 is fixedly connected to the outer side wall of the middle part of the tank body 1, the air outlet pipe 12 is fixed to the top of the tank body 1, and the liquid outlet pipe 13 is fixed to the bottom of the tank body 1. Both the air outlet pipe 12 and the liquid outlet pipe 13 are communicated with the internal space of the tank body 1. A centrifugal cylinder 2 is also arranged in the tank body 1. Optionally, the centrifugal cylinder 2 is arranged vertically, the feed pipe 11 is communicated to the lower end of the centrifugal cylinder 2, and the upper end of the centrifugal cylinder 2 is open; a first fan 3 is arranged in the centrifugal cylinder 2, the first fan 3 is coaxially arranged with the centrifugal cylinder 2, and the structure of the first fan 3 is the same as that of the fan of an aircraft turbofan engine to enhance the formation strength of the swirl when the first fan 3 rotates, thereby enhancing the effect of centrifugal separation of the mixture; when the first fan 3 is driven to rotate, the mixture introduced into the centrifugal cylinder 2 can form a swirl and flow upward in the centrifugal cylinder 2. During this process, the liquid phase with a larger density flows downward along the inner wall of the centrifugal cylinder 2 under the action of centrifugal force and gravity, while the gas phase with a smaller density can flow upward with the swirl to the upper part of the centrifugal cylinder 2 and is discharged through the air outlet pipe 12 on the tank body 1, and the liquid phase accumulates at the lower part of the tank body 1 and is discharged through the liquid outlet pipe 13; obviously, in order to prevent the liquid discharged from the liquid outlet pipe 13 from being entrained with gas, an anti-vortex device is arranged at the lower part of the tank body 1 corresponding to the position of the liquid outlet pipe 13. The anti-vortex device is in an umbrella shape and is composed of a top plate and a cross-shaped vertical vortex-breaking plate and is welded to the inner wall of the bottom of the tank body 1.

[0034] The turbofan swirl high-efficiency energy-saving gas separator provided by the embodiment of the present invention installs a first fan 3 in the centrifugal cylinder 2. The rotation of the first fan 3 will cause the introduced mixture to generate a swirl. Through the action of the centrifugal force generated by the rotation, the solid phase (solid particles) and the liquid phase with a larger density are in contact with the inner wall of the centrifugal cylinder 2. At the same time, the solid particles and tiny liquid droplets in the gas collide with the fan blades, which can promote the coalescence of the liquid droplets and form a liquid film on the inner wall of the centrifugal cylinder 2, and then flow into the bottom of the separator under the action of gravity and are discharged, thereby realizing efficient gas-liquid separation.

[0035] Further, the centrifugal cylinder 2 is arranged horizontally, a plurality of groups of first fans 3 are arranged along the axial direction of the centrifugal cylinder 2, a liquid discharge port 221 is opened at the lower part of the centrifugal cylinder 2 in the direction of gravity, an exhaust port 222 is also opened at the upper part of the centrifugal cylinder 2 in the direction of gravity, and a rotating shaft 223 is arranged along the circumferential direction of the centrifugal cylinder 2. Each first fan 3 is sleeved outside the rotating shaft 223.

[0036] Specifically, in the above embodiment, the centrifugal cylinder 2 is arranged vertically, and the liquid phase thrown to the inner wall of the centrifugal cylinder 2 flows downward along the inner wall of the centrifugal cylinder 2 under the action of gravity, while the gas phase flows upward to the upper part of the centrifugal cylinder 2 in the form of a swirl. During this process, the upward swirl will cause the liquid to be re-entrained, thereby reducing the separation effect; in this embodiment, the centrifugal cylinder 2 is arranged horizontally, as Figure 2As shown in the figure, the feed pipe 11 communicates with one end of the centrifugal cylinder 2, and multiple groups of first fans 3 are arranged inside the centrifugal cylinder 2. The multiple groups of first fans 3 are arranged at equal intervals along the central axis of the centrifugal cylinder 2. A rotating shaft 223 is also arranged inside the centrifugal cylinder 2. The rotating shaft 223 is coaxially arranged with the centrifugal cylinder 2. Each first fan 3 is sleeved outside the rotating shaft 223. All the first fans 3 can be driven to rotate synchronously by the same driving member 6. A driving mechanism for driving the rotating shaft 223 to rotate is also arranged inside the centrifugal cylinder 2. Optionally, as Figure 3 shown, the driving mechanism includes a motor and a gearbox. The motor is connected to the input shaft of the gearbox, and the output shaft of the gearbox is in transmission connection with the rotating shaft 223; thus, step-by-step separation is achieved, thereby improving the separation effect on the mixture. A liquid discharge port 221 is opened at the lower part of the centrifugal cylinder 2 in the direction of gravity. As Figure 3 shown, preferably, the number of liquid discharge ports 221 is the same as that of the first fans 3. In this way, it is convenient for the liquid phase between the two first fans 3 to be discharged from the centrifugal cylinder 2 through the corresponding liquid discharge ports 221 in time, so as to improve the step-by-step separation effect; an exhaust port 222 is opened at the upper part of the centrifugal cylinder 2. The exhaust port 222 is opened at one end of the centrifugal cylinder 2 away from the feed pipe 11. In this way, the mixed gas needs to pass through all the first fans 3 before it can be discharged to the outside of the centrifugal cylinder 2.

[0037] Furthermore, the centrifugal cylinder 2 includes a sleeve 21 and a cylinder body 22 with both ends closed. The sleeve 21 is sleeved on one end of the centrifugal cylinder 2. The feed pipe 11 communicates with the sleeve 21. An air inlet 224 is opened on the side wall of the cylinder body 22 at a position corresponding to the sleeve 21 along the tangent direction of the cylinder body 22 itself.

[0038] Specifically, in this embodiment, the centrifugal cylinder 2 includes a cylinder body 22 with both ends closed. The above-mentioned rotating shaft 223 is installed inside the cylinder body 22 and is coaxially arranged with the cylinder body 22. A sleeve 21 is sleeved on one end of the cylinder body 22. The inner diameter of the sleeve 21 is larger than the outer diameter of the cylinder body 22, and one end of the sleeve 21 is fixedly connected to the outer wall of the cylinder body 22. The other end of the sleeve 21 protrudes from the end of the cylinder body 22, and the other end of the sleeve 21 is fixedly connected to the inner wall of the tank body 1. As Figure 2 shown, the feed pipe 11 communicates with the inside of the sleeve 21. In addition, a plurality of air inlets 224 are opened on the side wall of the cylinder body 22 along the tangent direction of the cylinder body 22. The plurality of air inlets 224 are arranged in a circumferential array along the cylinder body 22; in this way, the mixture can be introduced into the inner wall of the cylinder body 22 from the tangent direction of the cylinder body 22, so that the mixture can initially form a swirl during the introduction stage, thereby reducing the impact on the blades of the first fan 3 and preventing the solid particles in the mixture from hitting the fan blades directly.

[0039] In another embodiment of the present invention, a screen group 4 is provided in the upper part of the tank body 1, and the screen group 4 includes a first screen plate 41, a second screen plate 42 and a third screen plate 43 distributed from bottom to top, and the mesh holes of the first screen plate 41, the second screen plate 42 and the third screen plate 43 gradually become smaller.

[0040] Specifically, Figure 2 As shown, in order to further enhance the removal effect of trace residual liquid and other impurities in the gas and realize efficient fine separation, in this embodiment, a screen group 4 is provided on the upper part of the tank body 1, and the screen group 4 includes a first screen plate 41, a second screen plate 42 and a third screen plate 43 arranged on the upper part of the tank body 1. The first screen plate 41, the second screen plate 42 and the third screen plate 43 are all disc-shaped, and all of them are metal or non-metallic wire mesh. The structural type is a dense screen form, which is used to remove foam in droplets, and the mesh holes of the three gradually become smaller, and the heights of the three gradually increase, thereby gradually improving the separation accuracy to achieve the best separation effect.

[0041] Furthermore, if Figure 2 As shown, the upper part of the tank body 1 is provided with second fans 9 corresponding to the first screen plate 41, the second screen plate 42 and the third screen plate 43 respectively, and each second fan 9 is arranged below the first screen plate 41, the second screen plate 42 and the third screen plate 43 respectively, so as to achieve efficient separation while maintaining low pressure loss.

[0042] In another embodiment of the present invention, a scraper assembly 5 is disposed inside the cylinder 22 , and the scraper assembly 5 is driven to move along the axial direction of the cylinder 22 to clean the inner wall of the cylinder 22 .

[0043] Furthermore, the scraper assembly 5 includes a scraper ring 51 , the outer diameter of the scraper ring 51 is equal to the inner diameter of the cylinder 22 , and a driving member 6 is provided on the cylinder 22 for driving the scraper ring 51 to move along the axial direction of the cylinder 22 .

[0044] Specifically, since the central axis of the cylinder 22 is arranged horizontally, during the separation process of the mixture, the liquid needs to flow along the circumferential inner wall of the cylinder 22 and slide from the top to the bottom. Since the inner cavity of the cylinder 22 is cylindrical, the flow path of the liquid is a spiral or curved path rather than a straight line, which results in more opportunities for solid particles in the liquid to adhere to the inner wall of the cylinder 22. After the solid particles accumulate on the inner wall of the cylinder 22, they will gradually occupy the flow channel space and change the original flow channel geometry. This change will cause uneven airflow distribution, destroy the symmetry and stability of the vortex, and thus reduce the separation effect of the mixture. In this embodiment, a scraper assembly 5 for cleaning the inner wall of the cylinder 22 is provided inside. Figure 3 , Figure 4 and Figure 5As shown, the scraper assembly 5 includes a scraper ring 51, the outer diameter of the scraper ring 51 is equal to the inner diameter of the cylinder 22, so that the scraper ring 51 can be in close contact with the cylinder 22 to achieve the best cleaning effect; a driving member 6 is also provided in the cylinder 22 to drive the scraper ring 51 to move along the axial direction of the cylinder 22. Optionally, the driving member 6 is a linear driving mechanism such as a screw arranged in the cylinder 22, the screw is arranged along the axial direction of the cylinder 22, and the screw penetrates the axial direction of the scraper ring 51 and is threadedly connected to the scraper ring 51, and a rotating driving member 6 such as a motor is also provided in the cylinder 22 to drive the screw to rotate (the screw and the motor are not shown in the figure); with such a configuration, when the motor drives the screw to rotate, the scraper ring 51 can move along the axial direction of the cylinder 22 under the guidance of the inner wall of the cylinder 22, and scrape off the attachments on the inner wall of the cylinder 22, thereby ensuring the symmetry and stability of the vortex formed in the cylinder 22.

[0045] Furthermore, the driving member 6 includes a winding roller 61 installed on the outer wall of the cylinder 22. The winding roller 61 is rotatably installed on the outside of the cylinder 22. A first motor 62 is also installed on the outside of the cylinder 22. The first motor 62 drives the winding roller 61 to rotate. A pull rope 63 is wound on the winding roller 61. Both ends of the pull rope 63 are respectively inserted into the interior of the cylinder 22 from positions near the two ends of the side wall of the cylinder 22, and both ends of the pull rope 63 are respectively connected to the two end surfaces of the scraper ring 51.

[0046] Specifically, in the above embodiment, a screw is arranged in the barrel 22, and the screw cooperates with the scraper ring 51 to form a screw slider mechanism, thereby driving the scraper ring 51 to reciprocate in the barrel 22. However, since the screw has a certain diameter, the interference with the swirl is relatively large, and the attachments scraped by the scraper ring 51 may enter into the screw thread during use, which is not conducive to the thread cooperation between the screw and the scraper ring 51. In this embodiment, the driving member 6 includes a winding roller 61 rotatably mounted on the outside of the barrel 22, such as Figure 3 and Figure 6 As shown, a pull rope 63 is wound on the winding roller 61, and the two ends of the pull rope 63 are inserted into the interior of the cylinder 22 from the side wall of the cylinder 22 near the two ends, and the two ends of the pull rope 63 are respectively connected to the two end surfaces of the scraper ring 51, and the outer wall of the cylinder 22 is also equipped with a first motor 62 for driving the winding roller 61 to rotate, and the output shaft of the first motor 62 is coaxially connected to the winding roller 61; when the winding roller 61 is driven by the first motor 62 to rotate forward or reverse, the pull rope 63 can pull the scraper ring 51 to move along the axial direction of the cylinder 22. Since the diameter of the pull rope 63 is much smaller than the diameter of the screw rod, the interference with the vortex in the cylinder 22 can be minimized, and the use of the pull rope 63 will not be affected by attachments; preferably, the central axis of the winding roller 61 is perpendicular to the central axis of the cylinder 22, so that the pull rope 63 can be arranged along the length direction of the cylinder 22 as much as possible, thereby reducing the wear of the pull rope 63.

[0047] Furthermore, the cross-section of the scraping ring 51 is a right trapezoid, and the inclined surface of the material hanging ring faces one end of the cylinder body 22 corresponding to the sleeve 21.

[0048] Specifically, in the above embodiment, since the scraping ring 51 needs to move along the axial direction of the cylinder body 22, and the scraping ring 51 itself has a certain size, a gap for the scraping ring 51 to pass through needs to be reserved between the fan blades of the first fan 3 and the inner wall of the cylinder body 22. As a result, part of the mixture directly leaks from the gap and fails to fully participate in the swirling motion generated by the rotation of the first fan 3, thereby reducing the separation effect of the mixture. In this embodiment, the cross-section of the scraping ring 51 is a right trapezoid (a right trapezoid includes an inclined side, a right side, and parallel long and short sides), and the inclined surface (the surface corresponding to the inclined side) of the right trapezoid faces one end of the cylinder body 22 corresponding to the sleeve 21, that is, one end of the cylinder body 22 where the feed port is opened. With such a setting, after driving the scraping ring 51 to move along the axial direction of the cylinder body 22 to complete the cleaning of the inner wall of the cylinder body 22, the scraping ring 51 can be driven to face any group of the first fans 3, showing the state as Figure 2 and Figure 3 shown. When the mixture passes through this group of the first fans 3, it can fully participate in the swirling motion generated by the rotation of this first fan 3, ensuring the separation effect of the mixture. The inclined surface on the scraping ring 51 has a guiding effect, reducing the influence on the swirl. At the same time, when the scraping ring 51 moves from one side of the exhaust port 222 of the cylinder body 22 to the intake port 224 side, that is, when the scraping ring 51 is driven to move from the Figure 3 right end to the left end of the cylinder body 22 in the view, the setting of this inclined surface can also enhance the shearing force of the scraping ring 51 on the attached substances, thereby reducing the resistance when the scraping ring 51 moves.

[0049] In another embodiment proposed by the present invention, the scraping assembly 5 further includes a material receiving ring 52. The axial dimension of the material receiving ring 52 is larger than that of the scraping ring 51. The scraping ring 51 is sleeved outside the material receiving ring 52. The scraping ring 51 is driven to drive the material receiving ring 52 to move along the axial direction of the cylinder body 22. The scraping ring 51 has a first position and a second position relative to the material receiving ring 52. A locking member 7 is provided on the scraping ring 51, and the locking member 7 is used to lock the scraping ring 51 at the first position or the second position.

[0050] Specifically, in the above embodiment, during the cleaning process of the inner wall of the cylinder body 22 by the scraping ring 51, as the attached substances scraped by the scraping ring 51 gradually increase, the attached substances will fall onto the fan blades of the first fan 3 under the action of gravity, affecting the rotation of the fan blades. If the inner wall of the cylinder body 22 is cleaned without stopping the machine (the first fan 3 keeps rotating), the fallen attached substances will hit the fan blades of the next first fan 3 through which the swirl passes, or reattach to the inner wall of the cylinder body 22 along with the swirl. In this embodiment, the scraping assembly 5 further includes a material receiving ring 52, as Figure 3 shown,Figure 4 and Figure 5 As shown, the axial dimension of the receiving ring 52 is greater than the axial dimension of the scraper ring 51, and the scraper ring 51 is sleeved on the outside of the receiving ring 52. The scraper ring 51 can move relative to the receiving ring 52. The scraper ring 51 has a first position and a second position relative to the receiving ring 52:

[0051] When in the first position, the scraper ring 51 is located on the left side of the receiving ring 52 in the axial direction. Figure 4 As shown, at this time, the right side of the receiving ring 52 and the inner wall of the cylinder 22 form an annular space, and the scraper ring 51 is driven to the side where the exhaust port 222 on the cylinder 22 is opened ( Figure 4 When the scraper ring 51 moves to the right side of the cylinder 22 in the middle), the attachments scraped off by the scraper ring 51 can be retained in the annular space, and when the scraper ring 51 and the receiving ring 52 are both facing any first fan 3, the scraper ring 51 is kept in the first position, thereby ensuring that the inclined surface of the scraper ring 51 can extend from the left end of the receiving ring 52 (the end of the receiving ring 52 corresponding to the air inlet 224 on the cylinder 22);

[0052] When in the second position, the scraper ring 51 is located on the right side of the receiving ring 52 in the axial direction. Figure 5 As shown, at this time, the left side of the receiving ring 52 and the inner wall of the cylinder 22 form another annular space, and the scraper ring 51 is driven to the side where the air inlet 224 on the cylinder 22 is opened ( Figure 5 When the scraper ring 51 moves to the left side of the cylinder 22 in the annular space, the attached matter scraped off by the scraper ring 51 can be retained in another annular space.

[0053] In order to enable the scraper ring 51 to drive the receiving ring 52 to move synchronously, and the scraper ring 51 can be adjusted between the first position and the second position, a locking piece 7 is also provided on the scraper ring 51. Optionally, the locking piece 7 includes a plug pin 71 arranged in the scraper ring 51, and the plug pin 71 is arranged along the radial direction of the scraper ring 51. Pin holes 521 matching the plug pin 71 are provided on the receiving ring 52 at the first position and the second position. The pin holes 521 are square holes. Preferably, the pin holes 521 are arranged to penetrate along the radial direction of the receiving ring 52, and the attachments entering the pin holes 521 can be pushed to the inner side of the receiving ring 52 by the plug pin 71, thereby avoiding the blockage of the pin holes 521; the end of the plug pin 71 that cooperates with the pin hole 521 is symmetrically provided with inclined surfaces, such as Figure 4 and Figure 5 As shown, the inclined surfaces are respectively arranged at both ends of the scraper ring 51 in the direction of the central axis, and a spring 72 is arranged in the scraper ring 51 to drive the plug pin 71 to extend into the pin hole 521. When the spring 72 is in a natural state, the plug pin 71 extends into the pin hole 521. In specific implementation, protrusions can be arranged on the inner walls of both ends of the cylinder 22 at positions corresponding to the receiving ring 52.

[0054] Before cleaning the barrel 22, the scraper ring 51 is in the first position relative to the receiving ring 52, that is, Figure 3 and Figure 4 In the state shown, the first motor 62 drives the winding roller 61 to rotate in the positive direction, and the pull rope 63 pulls the scraper ring 51 along the inner wall of the cylinder 22 to move toward the side where the exhaust port 222 is opened on the cylinder 22, that is, toward Figure 3 In the figure, the right end of the cylinder 22 moves. During this process, since the plug pin 71 is plugged into the pin hole 521, the material receiving ring 52 moves synchronously with the scraper ring 51. The end surface corresponding to the right angle side of the right-angled trapezoid on the scraper ring 51 cleans the inner wall of the cylinder 22. When the material receiving ring 52 contacts the protrusion in the cylinder 22, it is blocked and cannot move further. At this time, the pull rope 63 continues to pull the scraper ring 51, and the inclined surface on the plug pin 71 will shrink toward the inside of the scraper ring 51 under the pressure of the hole wall of the pin hole 521, thereby releasing the lock of the scraper ring 51. The scraper ring 51 moves relative to the receiving ring 52, and is adjusted from the first position to the second position. Then, the plug pin 71 is plugged into the other pin hole 521 driven by the spring 72, thereby locking the scraper ring 51 in the second position. During this process, the scraper ring 51 can also push the attachments gathered between the receiving ring 52 and the cylinder 22 to the outside of the receiving ring 52. Subsequently, the first motor 62 drives the winding roller 61 to rotate in the opposite direction, and the pull rope 63 pulls the scraper ring 51 along the inner wall of the cylinder 22 toward the side where the air inlet 224 on the cylinder 22 is opened, that is, toward Figure 3 As the left end of the cylinder 22 moves in the view, the scraper ring 51 and the receiving ring 52 move synchronously, and the scraper ring 51 remains in the second position. At this time, the end face corresponding to the inclined surface of the scraper ring 51 cleans the inner wall of the cylinder 22. When the receiving ring 52 contacts the protrusion provided on the inner wall of the other end of the cylinder 22, it is blocked and cannot move further. At this time, the pull rope 63 pulls the scraper ring 51 relative to the receiving ring 52 to move the scraper ring 51 from the second position to the first position. The connecting pin 71 locks the scraper ring 51 when the scraper ring 51 reaches the first position. In this process, the inclined surface of the scraper ring 51 can also push the attachments gathered between the receiving ring 52 and the cylinder 22 to the outside of the receiving ring 52.

[0055] In another embodiment of the present invention, a material gathering assembly 8 is provided at both ends of the cylinder 22. Figure 3 A discharge port 225 is provided at the lower part of the barrel 22 (the left end of the barrel 22 in the figure), and the discharge port 225 penetrates to the outside of the sleeve 21, and a partition block is provided at a position corresponding to the discharge port 225 in the sleeve 21 to prevent the attachments discharged from the discharge port 225 from entering the sleeve 21. The material gathering component 8 is used to push the attachments scraped off by the scraper ring 51 to the discharge port 225 or the corresponding liquid discharge port 221 (this liquid discharge port 221 is in the Figure 3The lower right end of the cylinder 22 in the view).

[0056] Further, the material gathering assembly 8 includes an inner gear ring 81 rotatably mounted on the inner end of the cylinder 22, the inner gear ring 81 is coaxially arranged with the cylinder 22, and the outer wall of the inner gear ring 81 is rotatably connected with a scraper 82, the scraper 82 is arranged along the axial direction of the inner gear ring 81, and the length of the scraper 82 is greater than the distance between the outer wall of the inner gear ring 81 and the inner wall of the cylinder 22, a torsion spring is arranged at the hinge position of the scraper 82 and the inner gear ring 81, the torsion spring maintains the side of the scraper 82 away from the inner gear ring 81 in contact with the inner wall of the cylinder 22, a second motor 83 is arranged in the cylinder 22 to drive the ring to rotate, and the output shaft of the second motor 83 is transmission-connected with the inner gear ring 81 through a spur gear;

[0057] With such arrangement, when the inner gear ring 81 is driven to rotate, the attachments pushed out by the scraper ring 51 can be pushed along the inner wall of the cylinder 22 toward the discharge port 225 or the corresponding liquid discharge port 221, so that the attachments can be discharged to the outside of the cylinder 22; in addition, in this embodiment, the scraper 82 can push the attachments toward the discharge port 225 or the liquid discharge port 221, and it is also equivalent to the protrusion in the above embodiment, that is, the receiving ring 52 will be blocked when it contacts the scraper 82, thereby realizing the adjustment of the scraper ring 51 between the first position and the second position; obviously, since the cross-section of the scraper ring 51 is a right-angled trapezoid, it is arranged at Figure 3 The scraper 82 at the left end of the cylinder 22 is also in a right-angle trapezoidal shape, thereby ensuring that the scraper ring 51 moves to Figure 3 When the left end of the cylinder 22 is viewed, the attachment pushed out by the scraper ring 51 between the receiving ring 52 and the inner wall of the cylinder 22 can also be pushed into the discharge port 225 by the corresponding scraper 82; and the scraper 82 is hinged to the inner gear ring 81, and the length of the scraper 82 is greater than the distance between the outer wall of the inner gear ring 81 and the inner wall of the cylinder 22, on the one hand, to prevent the scraper 82 from damaging the pull rope 63, on the other hand, when the scraper 82 revolves with the inner gear ring 81 to the discharge port 225 or the discharge port 22 1, the scraper 82 can rotate around the hinge axis on the inner gear ring 81 under the drive of the torsion spring, so that the scraper 82, which is away from the hinged side on the inner gear ring 81, can extend into the discharge port 225 or the liquid discharge port 221 (the dimension of the scraper 82 along the axial direction of the cylinder 22 is smaller than the dimensions of the discharge port 225 and the liquid discharge port 221 along the axial direction of the cylinder 22), so that the attached matter on the scraper 82 can be scraped off by using the side wall of the discharge port 225 or the liquid discharge port 221.
