Description

Technical Field

[0001] The invention relates to the technical field of anti-wear agent production, and in particular to a diesel anti-wear agent crystallization filtering device. Background Art

[0002] Diesel antiwear agent is a chemical additive specially designed to improve the lubricity of diesel fuel. Its main purpose is to reduce friction and wear inside diesel engines, especially key components such as fuel injection systems, thereby improving engine efficiency, reliability, durability and fuel economy. In the production of fatty acid-based diesel antiwear agents, unsaturated fatty acids composed of industrial-grade linoleic acid, linolenic acid, oleic acid, tall oil acid and their mixtures are generally used as the main raw materials. Most of the saturated fatty acids are removed by cooling crystallization and filtering to obtain a filtrate, and the filtrate is formulated to obtain a diesel antiwear agent product.

[0003] The patent document with publication number CN219848369U discloses a purification equipment for diesel anti-wear agent production, including box body one, box body two is arranged below box body one, a guide plate is arranged inside box body one, a fixing frame is fixedly connected to the guide plate, a filter screen one is arranged on the fixing frame, a scraping mechanism is arranged on box body one, a suspended matter filtering mechanism is arranged at the bottom position of box body two, a stabilizing mechanism is arranged on one side wall of the box body, the suspended matter filtering mechanism includes a partition, a waterproof electric telescopic rod and filter screen two, the scraping mechanism includes a motor, a rotating shaft, a connecting rod and a scraper, the patent can scrape off impurities on filter screen one to prevent filter screen one from being blocked, and at the same time can filter suspended matter (i.e. precipitated crystals) in the anti-wear agent through filter screen two to obtain an anti-wear agent without suspended matter, thereby realizing the purification of the anti-wear agent.

[0004] When the above-mentioned equipment is used to perform crystallization filtration on the anti-abrasive agent, although the filter screen 1 can be cleaned by the scraping mechanism, the impurities after scraping still remain in the filter screen 1 and are not discharged, so that after continuous filtration, the impurities accumulate inside and cause the filter screen 1 to be blocked. In addition, when the separated crystals are discharged to the outside, a small amount of solution may remain in the crystals and be discharged simultaneously, causing waste. Summary of the invention

[0005] The present invention provides a diesel anti-wear agent crystallization filtration device, which aims to solve the problem that the equipment in the related technology fails to discharge the scraped impurities in time, which may cause the filter screen to be blocked after continuous filtration.

DETAILED DESCRIPTION

[0041] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0042] like Figures 1 to 11 As shown, a diesel antiwear agent crystallization filtering device of the present invention comprises a reaction kettle 1, a drive shaft 21, a salvaging mechanism and a cleaning mechanism.

[0043] A feed port 11 is provided at the top of the reactor 1, a discharge port 12 is provided at the bottom of the reactor 1, a driving shaft 21 is arranged in the reactor 1 and rotates along the axis of the reactor 1, a salvaging mechanism is used to salvage crystals precipitated from the solution in the reactor 1 after cooling, so as to separate the crystals from the solution, and a cleaning mechanism is used to clean the salvaged crystals.

[0044] The salvaging mechanism includes a filter cloth 3 and a driving component 1. The filter cloth 3 is longitudinally arranged on the driving shaft 21 and can rotate synchronously with the driving shaft 21. The filter cloth 3 has a winding end 301 and a moving end 302. The driving component 1 is used to drive the winding end 301 to rotate, so that the moving end 302 moves toward or away from the winding end 301, so that the filter cloth 3 can switch between a flat state and a winding state. When in the flat state, the filter cloth 3 can salvage impurities in the reactor 1. When in the winding state, the filter cloth 3 can roll up the salvaged impurities on the filter cloth 3. Inside the filter cloth 3, the cleaning mechanism includes an extrusion cylinder 4, a scraper 41 and a drive component 2. The interior of the extrusion cylinder 4 is hollow, and the outer peripheral side of the extrusion cylinder 4 can contact the winding end 301 to extrude the wound filter cloth 3. During the winding process of the filter cloth 3, the scraper 41 is attached to the side wall of the extrusion cylinder 4. During the flattening process of the filter cloth 3, one end of the scraper 41 is tilted relative to the extrusion cylinder 4, so that impurities on the surface of the filter cloth 3 can be scraped off and collected in the extrusion cylinder 4. The drive component 2 is used to drive the scraper 41 to switch between a fitted state and a tilted state.

[0045] Specifically, Figures 1 to 9 As shown, in the initial state, the filter cloth 3 is in a flattened state. At this time, the raw material is added into the reactor 1 from the feed port 11, and the filter cloth 3 is driven to rotate synchronously by the drive shaft 21. During this process, the filter cloth 3 can stir the raw material in the reactor 1 to make the raw material temperature uniform, which is conducive to the cooling crystallization process. When crystals are precipitated in the reactor 1, as the filter cloth 3 continues to rotate, the crystals will be trapped on the front side of the filter cloth 3 in the rotation direction. At this time, the winding end 301 of the filter cloth 3 is driven to rotate by the drive component 1, so that the filter cloth 3 can be gradually wound up, and the crystals intercepted on the surface of the filter cloth 3 can be synchronously wound up in the filter cloth 3. During this process, the side wall of the extrusion cylinder 4 is always in contact with the winding end 301 of the filter cloth 3, so that the wound filter cloth 3 can be squeezed to be wound up. The solution contained in the crystals rolled up in the filter cloth 3 is squeezed out, and at this time, the scraper 41 on the extrusion cylinder 4 is attached to the side wall of the extrusion cylinder 4, and will not hinder the rolling of the filter cloth 3; when the filter cloth 3 is switched to the rolled state, the filter cloth 3 is located above the liquid surface, and the separation of the crystals and the solution is achieved. At this time, the rolling end 301 of the filter cloth 3 is driven by the driving component 1 to rotate in the opposite direction, and the moving end 302 of the filter cloth 3 is moved in the direction away from the rolling end 301, and the filter cloth 3 is gradually flattened. In this process, the scraper 41 can be driven by the driving component 2 to rotate relative to the extrusion cylinder 4, so that one end of the scraper 41 is tilted. At this time, the scraper 41 can scrape off the crystals attached to the surface of the filter cloth 3, and collect the scraped crystals in the extrusion cylinder 4, so as to clean the filter cloth 3.

[0046] In some embodiments, the salvaging mechanisms are provided in two groups and are symmetrically arranged along the axial direction of the driving shaft 21 , and the filter cloths 3 in the two groups of salvaging mechanisms are alternately rolled up and flattened.

[0047] Specifically, Figure 2 and Figure 3 As shown, two groups of salvaging mechanisms are provided to improve the effect of salvaging the crystals. In addition, the filter cloths 3 in the two groups of salvaging mechanisms are alternately rolled up and flattened, that is, when the filter cloths 3 in one group of salvaging mechanisms are in a rolled-up state, the filter cloths 3 in the other group of salvaging mechanisms are in a flattened state, so that the raw materials in the reactor 1 can be stirred by at least one filter cloth 3 at any time to ensure the stirring effect.

[0048] In some embodiments, the salvage mechanism also includes a reel 1 31 and a reel 2 32, and reel 1 31 and reel 2 32 are both arranged along the radial direction of the reactor 1, reel 1 31 is connected to the winding end 301 of the filter cloth 3, and is rotatably connected to the side wall of the drive shaft 21, reel 2 32 is connected to the moving end 302 of the filter cloth 3, and is slidably matched with the drive shaft 21 along the longitudinal direction, and the driving component 1 includes a winding structure and a reset structure, the winding structure is used to drive reel 1 31 to rotate, and the reset structure is used to drive reel 2 32 to move downward along the axial direction of the drive shaft 21.

[0049] Specifically, Figures 2 to 5 As shown, when the filter cloth 3 needs to be switched to the reeled state, the reel 1 31 is driven to rotate by the reeling structure, and the filter cloth 3 is gradually reeled on the outside of the reel 1 31. During this process, the reel 2 32 is pulled to move upward along the axial direction of the drive shaft 21. When the filter cloth 3 needs to be switched to the flattened state, the reel 1 31 is driven to reverse by the reeling structure, and the reel 2 32 is driven to move downward along the axial direction of the drive shaft 21 by the resetting structure, so as to pull the filter cloth 3 to be gradually flattened.

[0050] In some embodiments, the winding structure includes a rotating shaft 22, a bevel gear 1 23 and two bevel gears 24. The rotating shaft 22 is arranged inside the driving shaft 21 and can rotate synchronously with the driving shaft 21. The bevel gear 1 23 is fixedly sleeved on the outer side of the rotating shaft 22. The ends of the reels 1 31 in the two sets of salvaging mechanisms are both extended into the interior of the driving shaft 21 and are respectively connected to the two bevel gears 24. The two bevel gears 24 are symmetrically arranged along the axial direction of the rotating shaft 22 and are connected to the bevel gear 1 23. Meshing connection. In this embodiment, the specific structure for realizing the synchronous rotation of the driving shaft 21 and the rotating shaft 22 includes a motor 25, a bevel gear three 26 and two bevel gear fours 27. A top plate 13 is fixed to the upper part of the reactor 1. The motor 25 is arranged at the upper end of the top plate 13, and the output end is connected to the bevel gear three 26. The two bevel gear fours 27 are respectively sleeved on the outside of the driving shaft 21 and the rotating shaft 22, and the two bevel gear fours 27 are symmetrically arranged on both sides of the bevel gear three 26 and meshingly connected with the bevel gear three 26.

[0051] Specifically, Figures 2 to 6As shown, the starting motor 25 can drive the bevel gear three 26 connected thereto to rotate, and through the meshing transmission of the bevel gear three 26 and the bevel gear four 27, drive the two bevel gears four 27 to rotate, thereby driving the driving shaft 21 and the rotating shaft 22 to rotate. Through the rotation of the driving shaft 21, the filter cloth 3 can be driven to rotate synchronously to achieve the salvage of the crystal. Through the rotation of the rotating shaft 22, the bevel gear one 23 can be driven to rotate, and through the meshing transmission between the bevel gear one 23 and the bevel gear two 24, the bevel gear two 24 can be driven to rotate, and the two bevel gears two 24 rotate in opposite directions. Through the rotation of the bevel gear two 24, the reel one 31 connected thereto can be driven to rotate to achieve the winding and flattening of the filter cloth 3, and the two bevel gears two 24 rotate in opposite directions, which will make the reel one 31 in the two salvaging mechanisms rotate in opposite directions, so that the filter cloth 3 in the two salvaging mechanisms can be alternately wound and flattened.

[0052] In some embodiments, the reset structure includes a line roller 33 and a reset belt 34. The driving shaft 21 is fixedly connected to the mounting shaft 211. The line roller 33 is rotatably sleeved on the outer side of the mounting shaft 211, and a torsion spring 1 is provided between the line roller 33 and the mounting shaft 211. One end of the reset belt 34 is wound on the outer side of the line roller 33, and the other end is connected to the reel 2 32. A bottom plate 14 is provided at the lower part of the reactor 1, and the reset structure is provided on the lower side of the bottom plate 14. When the filter cloth 3 is in a flattened state, the moving end 302 of the filter cloth 3 contacts the bottom plate 14 to avoid omission of the filter cloth 3 during the salvage process.

[0053] Specifically, Figures 2 to 6 As shown, when the reel 1 31 is driven to rotate by the winding structure, the filter cloth 3 will be gradually wound on the outside of the reel 1 31, and at the same time, the reel 2 32 will be pulled to move upward along the axial direction of the driving shaft 21. During this process, the line roller 33 will be pulled to rotate, and the torsion spring 1 will be twisted to accumulate force to achieve the unwinding of the reset belt 34; when the reel 1 31 is driven to reverse by the winding structure, the accumulated force of the torsion spring 1 is released, driving the line roller 33 to rotate in the opposite direction, and the reset belt 34 is wound on the outside of the line roller 33. During this process, the reel 2 32 will be pulled to move downward along the axial direction of the driving shaft 21, and the filter cloth 3 will be pulled to be gradually flattened.

[0054] In some embodiments, a plurality of accommodating grooves 401 are provided on the extrusion cylinder 4, and the plurality of accommodating grooves 401 are arranged along the circumference of the extrusion cylinder 4. The scraper 41 is in an arc shape. When the scraper 41 is in a fitted state, the scraper 41 is located in the accommodating groove 401, so that the outer arc surface of the scraper 41 and the outer arc surface of the extrusion cylinder 4 are in the same circumferential direction. Both ends of the scraper 41 are connected to a rod 411, and the rod 411 is rotatably connected to the extrusion cylinder 4 through a second torsion spring.

[0055] Specifically, Figures 7 to 11As shown, during the winding process of the filter cloth 3, the scraper 41 is in a fitted state. At this time, the scraper 41 is located in the accommodating groove 401 provided on the extrusion cylinder 4, and the outer arc surface of the scraper 41 is in the same circumferential direction as the outer arc surface of the extrusion cylinder 4, so that when the extrusion cylinder 4 squeezes the filter cloth 3 wound on the outside of the reel 31, the scraper 41 will not cause any obstruction; during the flattening process of the filter cloth 3, the scraper 41 is driven by the driving component 2 to rotate around the rod 411, so that one end of the scraper 41 is tilted relative to the extrusion cylinder 4. At this time, the scraper 41 is in a tilted state and can contact the surface of the flattened filter cloth 3. As the filter cloth 3 continues to be flattened, the crystals attached to the surface of the filter cloth 3 are scraped off onto the scraper 41, and when the scraper 41 is subsequently restored to the fitted state, the scraped crystals are turned over to the extrusion cylinder 4 for collection, thereby realizing the separation of the crystals and the solution.

[0056] In some embodiments, drive component two includes a transmission structure, a push rod 42 and a driving structure. The transmission structure is used to drive the extrusion cylinder 4 to rotate while the reel 31 rotates. A mounting seat 412 is provided on the outer arc surface of the scraper 41. The push rod 42 is arranged along the radial direction of the extrusion cylinder 4 and is rotatably connected to the mounting seat 412. A torsion spring three 43 is provided on the mounting seat 412 for driving the push rod 42 to reset. The driving structure is used to drive the push rod 42 to gradually move toward the direction close to the axis of the extrusion cylinder 4 during the flattening of the filter cloth 3, so that the scraper 41 switches to a tilted state. In this embodiment, the rotation direction of the reel 31 when winding the filter cloth 3 is defined as clockwise.

[0057] Specifically, if Figures 3 to 11 As shown, during the clockwise rotation of the reel 31, the extrusion cylinder 4 can be driven to rotate clockwise. During this process, the scraper 41 maintains a fitted state under the action of the torsion spring 2 to avoid obstruction to the winding of the filter cloth 3. During the counterclockwise rotation of the reel 31, the extrusion cylinder 4 can be driven to rotate counterclockwise. When the end of the push rod 42 away from the extrusion cylinder 4 is directed toward the filter cloth 3, the scraper 41 will switch to a tilted state under the action of the driving structure to scrape off the crystals attached to the surface of the filter cloth 3, so that the crystals fall on the inner arc surface of the scraper 41. At this time, as the reel 31 continues to rotate, the push rod 42 can be separated from the force of the driving structure, so that the scraper 41 can be switched to the fitting state again under the action of the torsion spring 2. In this process, the crystals that have fallen on the inner arc surface of the scraper 41 can be flipped into the receiving groove 401, so that the crystals enter the extrusion cylinder 4 for collection, thereby cleaning the filter cloth 3. In addition, as the scraper 41 is quickly flipped, the scraper 41 will collide with the extrusion cylinder 4, knocking off the crystals attached to the inner arc surface of the scraper 41, thereby preventing the crystals from remaining on the scraper 41.

[0058] In some embodiments, the transmission structure includes a mounting plate 44 and a continuously variable transmission 45. A fixed seat 212 is fixedly connected to the outer side of the drive shaft 21. The fixed seat 212 is provided with a slide groove. The mounting plate 44 slides with the fixed seat 212 through the slide groove, and a spring 441 is connected between the mounting plate 44 and the fixed seat 212. The continuously variable transmission 45 includes a pulley 451, a transmission belt 452 and a reducing wheel 453. A thread is provided on the end of the reel 31 facing the drive shaft 21. The reducing wheel 453 includes two oppositely arranged conical disks, one of which is connected to the bevel gear 24, and the other is connected to a ring 46. The ring 46 is threadedly engaged with the reel 31. The pulley 451 and the extrusion cylinder 4 are both rotatably connected to the mounting plate 44, and the extrusion cylinder 4 can rotate synchronously with the pulley 451. The transmission belt 452 is sleeved on the outer side of the pulley 451 and the reducing wheel 453.

[0059] Specifically, Figures 4 to 10 As shown, the rotation of bevel gear 24 can drive the variable diameter wheel 453 and reel 1 31 to rotate. When reel 1 31 rotates to reel up filter cloth 3, the threaded cooperation between reel 1 31 and the corresponding conical disk can drive the conical disk to move along the axial direction of reel 1 31, so that the distance between the two conical disks gradually increases, and the contact radius of transmission belt 452 on variable diameter wheel 453 decreases. At this time, mounting plate 44 will move away from reel 1 31 under the action of spring 441, and drive pulley 451 and extrusion cylinder 4 connected to the rotation of mounting plate 44 to move synchronously, so as to ensure that transmission belt 452 drives pulley 451 and variable diameter wheel 453. As pulley 451 moves, the distance between pulley 451 and variable diameter wheel 453 will gradually increase, that is, the distance between reel 1 31 and extrusion cylinder 4 will increase. The distance between the two cone disks increases gradually. When the reel 31 rotates in the opposite direction and the filter cloth 3 is gradually flattened, the threaded transmission between the reel 31 and the corresponding cone disk can make the cone disk approach the other cone disk, increase the distance between the two cone disks, and increase the contact radius of the transmission belt 452 on the variable diameter wheel 453. At this time, the mounting plate 44 will move in the direction close to the reel 31 under the action of the transmission belt 452, and drive the extrusion cylinder 4 and the pulley 451 to move, so that the distance between the extrusion cylinder 4 and the reel 31 gradually decreases, so that during the rotation of the reel 31, the extrusion cylinder 4 can adjust its position according to the thickness of the filter cloth 3 rolled up on the outside of the reel 31, so as to avoid obstruction to the rolling and flattening of the filter cloth 3, and at the same time ensure that the extrusion cylinder 4 always squeezes the rolled filter cloth 3.

[0060] In some embodiments, the driving structure is a contact piece 47 that is sleeved on the outside of the extrusion cylinder 4. The contact piece 47 is fixedly connected to the mounting plate 44. The contact piece 47 has a contact surface 471 on the side facing the extrusion cylinder 4. The contact surface 471 has a head end and an end, and the distance between the contact surface 471 and the axis of the extrusion cylinder 4 gradually decreases from the head end to the end. In this embodiment, one side of the mounting seat 412 has a notch, while the other side has no notch, so that the push rod 42 can rotate toward the side with the notch on the mounting seat 412, but cannot rotate toward the other side of the mounting seat 412.

[0061] Specifically, if Figures 7 to 11 As shown, during the counterclockwise rotation of the extrusion cylinder 4, the scraper 41 and the push rod 42 will be driven to rotate synchronously. During this process, the push rod 42 will contact the contact surface 471 provided on the contact member 47, and gradually move from the head end to the end of the contact surface 471. Since the distance between the contact surface 471 and the axis of the extrusion cylinder 4 gradually decreases from the head end to the end, the push rod 42 will gradually move toward the direction close to the axis of the extrusion cylinder 4. As the push rod 42 moves, the scraper 41 will flip around the rod 411 relative to the extrusion cylinder 4, so that the other end of the scraper 41 is tilted relative to the extrusion cylinder 4, and the torsion spring 2 is twisted to store force. At this time, the scraper 41 is in a tilted state, and the tilted end can contact the filter cloth 3 in the flattening process to scrape off the crystals attached to the surface of the filter cloth 3. The scraped crystals will fall on the scraper On the inner arc surface of 41, as the extrusion cylinder 4 continues to rotate, the push rod 42 will break away from contact with the contact piece 47. At this time, the scraper 41 will flip around the rod 411 under the action of the torsion spring 2, so that the scraper 41 is re-fitted into the receiving groove 401. At this time, the scraper 41 switches to a fitted state. During this process, the crystals that fall on the inner arc surface of the scraper 41 will be flipped into the receiving groove 401 and enter the extrusion cylinder 4 for collection; during the clockwise rotation of the extrusion cylinder 4, the scraper 41 and the push rod 42 will be driven to rotate synchronously. During this process, the push rod 42 will directly contact the end of the contact surface 471. At this time, the push rod 42 will be forced to rotate relative to the mounting seat 412 to avoid the contact piece 47, so that the scraper 41 can continue to maintain a fitted state to avoid obstruction to the winding of the filter cloth 3.

[0062] In some embodiments, the cleaning mechanism also includes a conveying assembly arranged inside the extrusion cylinder 4, the conveying assembly includes a conveying cylinder 5 and an auger structure, the conveying cylinder 5 is arranged along the length direction of the extrusion cylinder 4 and is fixedly connected to the mounting plate 44, the conveying cylinder 5 is provided with a through opening 501, and the through opening 501 can be communicated with the accommodating groove 401, the auger structure includes an auger shaft 51 and an auger blade 52, the auger shaft 51 is arranged along the length direction of the conveying cylinder 5, and the end close to the drive shaft 21 is fixedly connected to the pulley 451, the other end of the auger shaft 51 is fixedly connected to the end of the extrusion cylinder 4, the auger blade 52 is installed on the outside of the auger shaft 51, the interior of the drive shaft 21 is hollow, and the lower end is an open end, and a connecting pipe 53 is connected between the end of the conveying cylinder 5 facing the drive shaft 21 and the drive shaft 21, so that the interior of the conveying cylinder 5 is communicated with the interior of the drive shaft 21.

[0063] Specifically, if Figures 4 to 9 As shown, during the counterclockwise rotation of the extrusion cylinder 4, the push rod 42 will contact the contact surface 471 provided on the contact piece 47 and move along the head end of the contact surface 471 to the end. During this process, the scraper 41 can switch to a tilted state, and as the filter cloth 3 continues to flatten, the crystals attached to the surface of the filter cloth 3 are scraped off. At this time, as the extrusion cylinder 4 continues to rotate, the push rod 42 will disengage from the end of the contact surface 471, so that the scraper 41 switches to a fitted state. At this time, the receiving groove 401 corresponding to the scraper 41 is just connected to the through hole 501 provided on the conveying cylinder 5, so that during the flipping of the scraper 41, the crystals dropped on the scraper 41 can be flipped into the receiving groove 401, and then enter the conveying cylinder 5 through the through hole 501, and under the action of the auger structure, the crystals are gradually conveyed to the end of the conveying cylinder 5 facing the drive shaft 21, so that the crystals can enter the interior of the drive shaft 21 through the connecting pipe 53, and be discharged from the lower end of the drive shaft 21 for collection.
