Description

Technical Field

[0001] This invention relates to the field of material storage container technology, specifically a buffer filling tank for the production of diesel anti-wear agents. Background Technology

[0002] In the production and filling process of diesel anti-wear agents, the buffer tank plays a crucial role in balancing the production cycle and stabilizing the filling pressure. Because diesel anti-wear agents are typically fatty acid-based or fatty acid ester-based organic compounds with high viscosity, they are prone to foaming during transfer and feeding. When using a top-feed method, the material impacting the liquid surface entrains a large amount of air. Since high-viscosity materials dissipate foam slowly, a thick foam layer quickly forms on the liquid surface, severely interfering with the accuracy of liquid level detection, affecting the accurate control of the filling volume, and also accelerating material oxidation, adversely impacting product quality.

[0003] In actual filling production, when material falls into the tank from the top feed inlet, it impacts the liquid surface and entrains a large amount of air. Due to the high viscosity of diesel anti-wear agents and their slow foam dissipation, a thick foam layer can quickly form on the liquid surface, directly affecting the accurate judgment of the liquid level sensor, leading to filling volume deviation and decreased filling efficiency. Furthermore, there is a lack of active and effective physical means to eliminate existing foam or foam present on the liquid surface during the feeding process. For high-viscosity materials like diesel anti-wear agents, material flow and liquid surface fluctuations can also carry air and form foam. Simply changing the feeding method is insufficient to completely prevent foam accumulation. More importantly, the existing structure lacks means to actively and physically eliminate existing foam on the liquid surface, causing foam to continuously affect production once it forms. In actual production, the only solution is often to add defoamers or other chemical methods, which not only introduces foreign substances but may also affect the purity and performance of the material formulation.

[0004] Therefore, for buffered filling tanks in the production of diesel anti-wear agents, how to reduce the impact of feeding while actively and continuously physically eliminating foam on the liquid surface using the existing structure inside the tank is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a buffered filling tank for the production of diesel anti-wear agents, in order to overcome the shortcomings mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a buffer-type filling tank for the production of diesel anti-wear agents, comprising a tank body having an inlet and an outlet; and further comprising: A feed pipe is vertically installed inside the tank, with its top end connected to the feed inlet and its bottom end located above the bottom of the tank. Several guide tubes are arranged in a ring around the feed pipe and parallel to the feed pipe, and the guide tubes rotate along an axis; A floating roof is fitted around the outside of the feed pipe and the guide pipe, and floats vertically with the liquid level in the tank. The first rotating component is rotatably connected to the outer peripheral edge of the floating plate. The first rotating component is provided with several collecting parts for gathering the foam on the liquid surface. The second rotating component is rotatably connected to the upper middle part of the floating plate. The second rotating component is provided with a defoaming part, which reciprocates in the vertical direction to physically eliminate the gathered foam. A transmission mechanism is disposed between the first rotating member and the second rotating member. When the conduit rotates, it drives the first rotating member and the second rotating member to rotate in opposite directions, and simultaneously drives the defoaming part to perform vertical reciprocating motion.

[0007] Preferably, the transmission mechanism includes: A plurality of catheter toothed rings are respectively axially limited and sleeved on the outside of each catheter, so that the catheter toothed rings rotate synchronously relative to the catheter and slide along its axial direction; The first rotating component is a circular ring with a gap between its outer peripheral edge and the inner wall of the tank. Its inner ring is fixedly provided with an inner toothed ring, which meshes with the outer teeth of each of the guide tube toothed rings. The second rotating component is a feed tube toothed ring, which is sleeved on the outside of the feed tube, and the feed tube toothed ring meshes with the inner teeth of each of the guide tube toothed rings.

[0008] Preferably, the collecting part comprises a plurality of scrapers, each of which is spaced apart at the outer peripheral edge of the first rotating member; The scraper includes a horizontal section and a vertical section. The outer side of the vertical section is close to the inner wall of the tank and is used to push and gather the foam distributed on the liquid surface toward the area where the defoaming part is located when rotating.

[0009] Preferably, a cam post is fixedly provided on the second rotating component, and a cam groove is formed on the annular surface of the cam post; the cam groove is an annular groove with a wave-like structure that undulates up and down along the annular surface of the cam post; A connecting frame is fixed to the floating plate, and a connecting rod is rotatably connected to the top of the connecting frame. The middle part of the connecting rod is located at the connection point with the connecting frame to form a lever fulcrum. One end of the connecting rod is inserted into the cam groove and slides along its groove, while the other end is connected to the defoaming part. When the second rotating component drives the cam column to rotate, one end of the connecting rod slides along the cam groove, and the connecting rod swings with the rotating connection point on the connecting frame as the fulcrum. Its other end drives the defoaming part to move up and down in the vertical direction in the opposite direction.

[0010] Preferably, the defoaming section is located in the area above the scraper, and its lower end has a plurality of spike structures.

[0011] Preferably, a sliding sleeve is provided on the outer side of the catheter, and the toothed ring of the catheter is connected to the catheter through the sliding sleeve; The inner wall of the sliding sleeve is provided with a limiting key, and the outer wall of the conduit is provided with a corresponding axially extending limiting groove. The limiting key and the limiting groove slide together to form the conduit toothed ring being axially limited and sleeved on the outside of the conduit. The bottom end of the sliding sleeve is rotatably connected to the top of the floating disk, allowing the sliding sleeve and the guide tooth ring to rise and fall vertically with the floating disk, while also allowing the sliding sleeve and the guide tooth ring to rotate independently relative to the floating disk.

[0012] Preferably, the bottom end of the feed pipe is provided with a water distribution device, which includes a feed rectification chamber and an annular water distribution plate; The annular water distribution plate has an annular flow channel inside, and a plurality of tangential nozzles are provided on its outer ring surface. The tangential nozzles open along the tangential direction of the annular water distribution plate.

[0013] Preferably, a rotating impeller is fixedly connected to the bottom end of each of the ducts, and the position of the rotating impeller corresponds to the position of the tangential nozzle; During feeding, the material is ejected tangentially through the tangential nozzle, impacting the rotating impeller to drive the guide tube to rotate.

[0014] Preferably, the top and bottom of the tank are provided with support frames; The upper and lower ends of the feed pipe are respectively fixedly connected to the support frame; The upper and lower ends of each of the conduits are rotatably connected to the support frame via bearings.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by placing the bottom of the feed pipe above the bottom of the tank and using a tangential nozzle and a rotating impeller, allows the material to enter the tank smoothly from the bottom in a tangential flow, fundamentally avoiding the problem of excessive foaming caused by the impact of traditional top-feeding on the liquid surface. Simultaneously, the kinetic energy of the feed liquid flow itself drives the rotation of the guide pipe, eliminating the need for an external power source and achieving energy self-sufficiency. 2. After the conduit of the present invention rotates, it drives the first rotating component and the second rotating component to rotate in opposite directions through the transmission mechanism. The scraper on the first rotating component sweeps and gathers the foam dispersed on the liquid surface along the circumferential direction to the area below the defoaming part. The cam column on the second rotating component drives the defoaming part to move up and down in the vertical direction through the connecting rod. The spike structure continuously punctures and breaks the gathered foam, thereby realizing the active physical elimination of foam on the liquid surface. The bottom feeding reduces foam generation and the active defoaming on the liquid surface work together to keep the liquid surface in the tank relatively clean during the feeding process. This effectively improves the accuracy of liquid level detection and filling volume control, while avoiding the problem of material oxidation and rancidity caused by long-term foam accumulation, thus ensuring product quality. 3. The floating plate of the present invention automatically rises and falls with the liquid level, and during the rising process, the first rotating component rises synchronously and rotates itself to form a spiral upward motion, so that the scraper can continuously act on the foam layer on the liquid surface in a spiral trajectory, and the foam collection and elimination are more uniform and thorough. No manual intervention is required. The entire defoaming process runs automatically with the start and stop of feeding. The structure is compact and the operation is reliable.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 5 The present invention provides a buffer filling tank for the production of diesel anti-wear agent, including a tank body 10, with a feed inlet 11 at the top and a discharge outlet 12 at the bottom.

[0020] In this embodiment, a vertical feed pipe 20 is provided inside the tank body 10. The top end of the feed pipe 20 is connected to the feed inlet 11 to introduce upstream materials into the tank. Typically, negative pressure feeding is used during production. This involves evacuating air from the tank body 10 via a downstream filling pump or an external vacuum system to create negative pressure inside the tank. The pressure difference then draws the upstream materials into the tank through the feed pipe 20. The bottom end of the feed pipe 20 is located above the bottom of the tank body 10. This arrangement ensures that the feed outlet is always below the liquid surface, preventing materials from falling freely from a height and impacting the liquid surface, thus avoiding the generation of excessive foam. The bottom end of the feed pipe 20 is connected to a feed rectifying chamber 21. Below the feed rectifying chamber 21 is an annular water distribution plate 22. An annular flow channel is formed inside the annular water distribution plate 22, and several tangential nozzles 23 are evenly arranged on its outer circumferential wall. The tangential nozzles 23 open along the tangential direction of the annular water distribution plate 22. Under negative pressure, the material enters the feed rectifier chamber 21 through the feed pipe 20 and is buffered and stabilized. Then, it is sprayed out horizontally along the tangential direction by the tangential nozzles 23 of the annular water distribution plate 22. This not only achieves stable bottom feeding, but also provides liquid kinetic energy for the subsequent drive of the rotating impeller 31.

[0021] In this embodiment, a number of guide tubes 30 are evenly arranged around the feed pipe 20 with the feed pipe 20 as the center. That is, the number of guide tubes 30 are arranged in a ring around the feed pipe 20 and are parallel to the feed pipe 20. A rotating impeller 31 is fixedly connected to the bottom end of each guide tube 30. The position of the rotating impeller 31 corresponds one-to-one with the position of the tangential nozzle 23.

[0022] When the material is ejected at high speed from the tangential nozzle 23, the liquid flow directly impacts the blades of the rotating impeller 31, driving the rotating impeller 31 to rotate the guide tube 30 along its own axis. The advantage of this driving method is that the entire defoaming system does not require an external motor or reducer, and is driven entirely by the kinetic energy of the feed liquid flow itself. This simplifies the structure and avoids the need for additional dynamic sealing ports on the tank, ensuring the tank's sealing performance.

[0023] In this embodiment, the tank body 10 is provided with support frames 80 at both the top and bottom. The upper and lower ends of the feed pipe 20 are fixedly connected to the support frames 80 to keep them stationary. The upper and lower ends of each guide pipe 30 are rotatably connected to the support frame 80 through bearings 81. The bearings 81 bear the radial load of the guide pipe 30 while ensuring its flexible rotation.

[0024] In this embodiment, a float 40 is fitted around the outside of the feed pipe 20 and the conduit 30. The float 40 is made of a material with a density between that of the material and air, allowing it to float on the liquid surface and drift vertically with the liquid level in the tank. The float 40, covering the liquid surface, effectively suppresses localized liquid surface fluctuations caused by feeding or liquid sloshing, thus stabilizing the liquid surface. The design of the float 40 always floating on the liquid surface ensures that the defoaming components installed on it are always aligned with the foam layer, allowing it to work effectively regardless of the liquid level.

[0025] Given the high viscosity of diesel anti-wear agents, foam often doesn't float uniformly across the entire surface during actual production, but rather tends to adhere and accumulate at the tank wall edges. Therefore, designing the collection section as a scraper close to the tank wall allows for targeted foam removal and collection below the defoaming section, improving foam collection efficiency. Based on these considerations, the preferred embodiment in this case is as follows: A first rotating component 50 is rotatably connected to the outer periphery of the floating plate 40. The first rotating component 50 is circular and has a gap between its outer periphery and the inner wall of the tank 10. An internal toothed ring 52 is fixedly provided on its inner ring. Three collection sections 51 are spaced apart on the outer periphery of the first rotating component 50. Each collection section 51 is a scraper, which consists of a horizontal section and a vertical section. The outer side of the vertical section is close to the inner wall of the tank 10. Because the viscosity of diesel anti-wear agent is high, foam tends to adhere to and accumulate on the edge of the inner wall of the tank 10 rather than being evenly distributed across the entire liquid surface. By placing the vertical section of the scraper close to the tank wall, foam can be preferentially peeled off from the cylinder wall and swept and gathered towards the central area during rotation, facilitating centralized elimination. The scraper is positioned below the first rotating component 50, at the boundary between the liquid surface and the floating plate 40. This location is precisely the dividing area between the foam layer and the liquid material. During the feeding process, the first rotating component 50 rotates along its own axis and rises synchronously with the floating plate 40, forming a spiral upward motion. This drives the scraper to continuously advance near the liquid surface in a spiral trajectory. This spiral propulsion method allows the horizontal section of the scraper to not only perform single circumferential shearing on the foam but also superimpose axial progressive shearing force, forming a spiral tearing and crushing of the foam layer. This efficiently breaks down larger foam clumps, which are then finally punctured and eliminated by the defoaming section 61, significantly improving the overall defoaming efficiency.

[0026] A second rotating component 60 is rotatably connected to the upper middle part of the floating plate 40. The second rotating component 60 is a feed pipe toothed ring, which is sleeved on the outside of the feed pipe 20 and can rotate freely relative to the feed pipe 20. A cam post 62 is fixedly installed on the second rotating component 60, and a cam groove 65 is opened on the annular surface of the cam post 62. In this embodiment, the shape and structure of the cam groove 65 is: an annular groove opened on the annular surface of the cam post 62, with a wave-like structure that undulates up and down along the annular surface of the cam post 62; a connecting frame 63 is fixedly connected to the floating plate 40, and a connecting rod 64 is rotatably connected to the top of the connecting frame 63. The middle part of the connecting rod 64 is located at the connection point with the connecting frame 63 to form a lever fulcrum. One end of the connecting rod 64 is inserted into the cam groove 65 and slides along its groove, and the other end is connected to the defoaming part 61.

[0027] When the second rotating component 60 drives the cam column 62 to rotate, one end of the connecting rod 64 slides along the cam groove 65. Due to the axial height difference of the groove, this end is guided to make continuous up-and-down reciprocating motion. The connecting rod 64 swings around the rotating connection point on the connecting frame 63 as the fulcrum, and its other end drives the defoaming part 61 to move up and down in the vertical direction in the corresponding opposite direction. This structure converts the unidirectional rotational motion of the cam column 62 into the linear reciprocating motion of the defoaming part 61 without the need for an additional reversing mechanism. The structure is simple and compact, and the transmission is reliable. The defoaming part 61 is located in the area above the scraper, and its lower end has several spike structures 611. In this way, the foam that is peeled off from the tank wall and gathered by the scraper is exactly below the defoaming part 61. Under the action of lever transmission, the defoaming part 61 reciprocates in the vertical direction, and uses the spike structures 611 to continuously puncture and break the gathered foam, realizing a complete linkage from foam collection to physical elimination.

[0028] In this embodiment, the conduit 30 is linked to the first rotating member 50 and the second rotating member 60 through a transmission mechanism. Specifically, each conduit 30 is fitted with a conduit toothed ring 70 on its outer side, and the conduit toothed ring 70 is connected to the conduit 30 through a sliding sleeve 71. The sliding sleeve 71 is fitted on the outer side of the conduit 30, and a limiting key is provided on the inner wall of the sliding sleeve 71. The outer wall of the conduit 30 is correspondingly provided with an axially extending limiting groove 72. The limiting key and the limiting groove 72 are slidably engaged to limit the conduit toothed ring 70 axially and fit it on the outer side of the conduit 30, so that the conduit toothed ring 70 can rotate synchronously with the conduit 30 and slide along its axial direction. The bottom end of the sliding sleeve 71 is connected to the top of the floating disk 40 through a thrust bearing or other rotating connecting parts, so that the sliding sleeve 71 and the conduit toothed ring 70 can rise and fall with the floating disk 40 in the vertical direction, while allowing the sliding sleeve 71 and the conduit toothed ring 70 to rotate independently relative to the floating disk 40.

[0029] The inner toothed ring 52 of the first rotating member 50 meshes with the outer teeth of each guide tube toothed ring 70, and the second rotating member 60 meshes with the inner teeth of each guide tube toothed ring 70. Since the inner toothed ring 52 and the second rotating member 60 mesh with the radial sides of the guide tube toothed ring 70 respectively, when the guide tube 30 rotates, the first rotating member 50 and the second rotating member 60 rotate in opposite directions, i.e., they rotate in opposite directions. This opposite rotation design mechanically links the circumferential sweeping motion of the scraper with the up-and-down reciprocating motion of the defoaming section, eliminating the need for a separate control mechanism.

[0030] The specific working process is as follows: During feeding, the material enters the feed pipe 20 from the feed inlet 11, enters the annular water distribution plate 22 through the feed rectification chamber 21, and is sprayed out at high speed along the tangential direction from the tangential nozzle 23. The liquid flow impacts the rotating impeller 31, driving the guide tube 30 to rotate. The guide tube 30 drives the sliding sleeve 71 and the guide tube toothed ring 70 to rotate synchronously through the limiting groove 72 and the limiting key. The outer teeth of the guide tube toothed ring 70 drive the inner toothed ring 52, driving the first rotating component 50 to rotate. The scraper on the first rotating component 50 sweeps and gathers the foam dispersed on the liquid surface towards the central area along the circumferential direction. At the same time, the inner teeth of the guide tube toothed ring 70 drive the second rotating component 60 to rotate in the opposite direction. The cam column 62 on the second rotating component 60 rotates with it. The cam groove 65 drives one end of the connecting rod 64 to slide up and down along the cam groove 65. The connecting rod 64 swings with the rotating connection point on the connecting frame 63 as the fulcrum, and its other end drives the defoaming part 61 to move up and down in the vertical direction. The spiked structure 611 at the lower end of the defoaming section 61 continuously punctures and breaks the foam gathered by the scraper during reciprocating motion, thereby achieving physical elimination of the foam.

[0031] As the feed rate increases, the liquid level gradually rises, and the float 40 floats upward along the feed pipe 20 and guide pipe 30 under the action of buoyancy. During the ascent, the float 40 rotates synchronously with the first rotating component 50, causing the collection section 51 to form a spiral upward motion trajectory. This spiral motion allows the collection section 51 to continuously sweep the entire foam layer on the liquid surface along a spiral path, resulting in more uniform and thorough foam collection and elimination, avoiding the problem of local foam leakage caused by simple rising and falling.

[0032] During the discharge stage, the material is discharged outward through the discharge port 12 at the bottom of the tank 10. At this time, there is no liquid flow into the feed pipe 20, the tangential nozzle 23 no longer sprays material, the rotating impeller 31 loses its driving source and remains stationary, and the guide tube 30 naturally stops rotating. To further ensure that the guide tube 30 does not accidentally reverse during non-feeding periods, such as slight rotation caused by liquid level drop disturbance or reverse flow of liquid in the tank, a one-way rotation device, such as a one-way bearing or ratchet mechanism, can be installed between the guide tube 30 and the bearing 81 of the support frame 80, so that the guide tube 30 can only rotate in the direction of feed drive and is locked in the reverse direction. In this way, when the liquid level drops during discharge, the float 40 falls back naturally with the liquid level under the action of gravity, the guide tube 30 does not rotate, and all moving parts are reliably maintained in a standby state, preparing for the next round of feeding and defoaming.

[0033] To improve the structural stability of the tank, support frames 80 are installed at the top and bottom of the tank 10. The upper and lower ends of the feed pipe 20 are fixedly connected to the support frames 80, and the upper and lower ends of the guide pipe 30 are rotatably connected to the support frames 80 through bearings 81, ensuring the positional accuracy and rotational reliability of each component during long-term operation.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
