Description

Technical Field

[0001] This invention relates to the field of pesticide formulation processing technology, specifically to a high-speed grinding device for pesticide suspensions with temperature control and anti-crystallization properties. Background Technology

[0002] Pesticide suspension concentrates are highly suspended, flowable, and stable liquid formulations formed by uniformly dispersing solid pesticide technicals that are insoluble or slightly soluble in water in water through wet ultra-fine grinding with the help of wetting agents, dispersants, thickeners, and other adjuvants. They consist of active ingredients, water, dispersants, wetting agents, thickeners, antifreeze agents, defoamers, etc. Using water as a medium, they are environmentally friendly water-based formulations with advantages such as no dust, no organic solvents, non-flammable and explosive, safe storage and transportation, high suspension rate, good adhesion and efficacy, and low phytotoxicity. They are diluted with water and sprayed before use and are widely used for insecticidal, fungicidal, and herbicide applications.

[0003] Traditional grinding devices generally adopt a fixed-gap grinding structure, where the distance between the grinding roller and the cavity wall remains constant. The fixed flow channel is prone to forming a flow dead zone in the cavity. Especially in high solids content and high viscosity systems, material retention can induce bridging or even blockage, which seriously affects the stability and continuity of equipment operation, and thus affects the grinding effect.

[0004] Based on this, the present invention designs a high-speed grinding device for pesticide suspension with temperature control and anti-crystallization to solve the above problems. Summary of the Invention

[0016] As a further embodiment of the present invention, the output shaft of the working motor is connected to a connecting rod, the connecting rod is rotatably connected to the grinding cylinder through a bearing, the connecting rod passes through the secondary gear, the rotating sleeve and the fixing cover and is disposed in the through cavity, and a conical disk is fixedly connected to one end of the connecting rod, and multiple helical blades are fixedly connected at equal intervals on the conical disk.

[0017] As a further embodiment of the present invention, the main bevel gear and the secondary bevel gear mesh with each other and are both disposed within the protective cover. The movable sleeve passes through the protective cover and is slidably connected to the protective cover. Limiting plates are fixedly connected to the inner walls on both sides of the movable sleeve.

[0019] As a further embodiment of the present invention, the rotating roller slides through the fixed sleeve and is slidably engaged with the fixed sleeve, the protrusion slides in the annular guide groove, and I-shaped rods are fixedly connected to both sides of the connecting hoop. The narrow part of the I-shaped rod slides with the inclined top groove, and the thick end of the I-shaped rod abuts against the movable frame wall.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a drive motor and a working motor. The drive motor, via a connecting shaft, rotates the main gear and the main bevel gear. The meshing of the main gear and the auxiliary gear causes the auxiliary gear to drive the rotating sleeve to rotate synchronously. Because the limiting plate slides within the limiting groove, the rotating sleeve can synchronously drive the movable sleeve to rotate. The rotating movable sleeve, through the fixed cover, drives the grinding cone roller to rotate within the conical cavity of the grinding cone. Simultaneously, the meshing transmission between the main bevel gear and the auxiliary bevel gear drives the rotating roller to rotate around its own axis. During this process, the inclined annular guide groove on the rotating roller pushes against the protrusion, causing the fixed sleeve and the movable frame to slide back and forth along the fixed rod. When the movable frame moves, it pushes against the I-shaped rod through the inclined groove wall of the inclined top groove, causing the I-shaped rod to drive the connecting hoop and the movable sleeve to move up and down. This allows the grinding cone roller to reciprocate and move up and down while rotating, changing the grinding... The grinding gap between the grinding cone roller wall and the conical cavity wall of the grinding cone cylinder is formed by the lifting and lowering movement of the grinding cone roller. The fixed tube can slide and extend within the sliding cavity, while the working motor can rotate the connecting rod, causing the connecting rod to drive the conical disk and the spiral blade to rotate at high speed. This causes the conical disk to agitate and propel the ground suspension through the spiral blade, allowing the ground suspension to enter the fixed tube through the feed port. The suspension is then propelled upward along the cavity by the spiral blade and flows out from the discharge port on the fixed cover, re-entering the grinding gap. This forms a forced internal circulation grinding channel, allowing the suspension to undergo multiple reciprocating compression and grinding between the grinding cone roller and the grinding cone cylinder. This achieves multiple circulation grinding of the suspension, forming a dynamic variable diameter space. This effectively avoids the dead zone or bridging phenomenon caused by material retention in traditional fixed gap grinding, improving operational stability and grinding effect. 2. This invention uses an electric push rod to move the movable cover downwards, causing the discharge port on the movable cover to detach from the sealing block, thus forming a discharge channel. At this time, the finished suspension accumulated in the grinding cone passes through the discharge port under the action of gravity, falls to the conical bottom of the grinding cylinder, and is discharged from the discharge pipe. When the discharge channel is fully open, the push cylinder abuts against the movable ring. Then, the electric push rod continues to move the movable cover downwards, causing the push cylinder to push the movable ring downwards and compress the return spring. During this process, the movable ring squeezes the slide rod through the inclined groove, forcing the slide rod to move along the transverse direction on the fixed ring. The trough slides, which in turn drives the connecting ring and scraper to rotate on the conical inner wall of the grinding cylinder. Within the travel stroke of the movable ring, the movable cover is pushed and pulled back and forth, thereby realizing the reciprocating scraping motion of the scraper. This allows the scraper to remove the sticky material and reduce material residue. Meanwhile, the liquid pump can draw water from the cooling water tank and continuously deliver it to the cooling pipe. The water in the cooling pipe absorbs the heat generated during the grinding process. Finally, the water that has absorbed heat flows back to the cooling water tank through the water inlet pipe to cool down and restore its temperature, forming a closed-loop heat exchange circuit to achieve temperature control and prevent crystallization.

[0032] 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.

[0033] Please see Figures 1-9 The present invention provides a technical solution:

[0034] A high-speed grinding device for a temperature-controlled, anti-crystallization pesticide suspension includes a grinding cylinder 1 and a cooling water tank 2. The grinding cylinder 1 is disposed on one side of the cooling water tank 2, and a support frame 3 is fixedly connected to the grinding cylinder 1. A cavity 4 is formed in the wall between the outer and inner walls of the grinding cylinder 1, and a cooling pipe 401 is fixedly installed in the cavity 4. A liquid pump 201 is fixedly installed on one side of the cooling water tank 2. An outlet pipe 202 and an inlet pipe 203 are fixedly connected to the cooling water tank 2. A delivery pipe 204 is fixedly connected above and to one side of the liquid pump 201. The delivery pipe 204 on one side of the liquid pump 201 is connected to the outlet pipe 202, and the delivery pipe 204 above the liquid pump 201 is connected to one end of the cooling pipe 401. The other end of the cooling pipe 401 is connected to the inlet pipe 203.

[0035] During operation, the liquid pump 201 pumps the low-temperature water in the cooling water tank 2 into the cooling pipe 401. The circulating water absorbs the heat generated during the grinding process. The heated cooling water returns to the cooling water tank 2 through the inlet pipe 203 for heat exchange and cooling, thereby controlling the internal temperature and preventing crystallization.

[0036] A packing pipe 5 is fixedly connected to one side of the upper part of the grinding cylinder 1, and a discharge pipe 6 is fixedly connected to the lower part of the grinding cylinder 1. The lower inner wall of the grinding cylinder 1 is tapered around the discharge pipe 6. A grinding cone 8 is fixedly connected inside the grinding cylinder 1. A return spring 51 is fixedly connected to the lower inner wall of the grinding cylinder 1. A movable ring 52 is fixedly connected to one end of the return spring 51. Multiple oblique grooves 53 are evenly spaced on the movable ring 52. A fixed ring 13 is fixedly connected to the lower part of the grinding cone 8. The lower part of the fixed ring 13 is fixedly connected to the tapered inner wall of the grinding cylinder 1. Multiple transverse grooves 47 are evenly spaced on the fixed ring 13. A connecting ring 48 is rotatably installed inside the fixed ring 13. Multiple scrapers 50 are fixedly connected to the lower part of the connecting ring 48 at equal intervals. The scrapers 50 are in close contact with the tapered inner wall of the grinding cylinder 1. The connecting ring 48 is in close contact with the inner wall of the fixed ring 13, and multiple sliding rods 49 are fixedly connected to the connecting ring 48 at equal intervals. The sliding rods 49 slide in cooperation with the transverse grooves 47 and the oblique grooves 53.

[0037] The grinding cone 8 has a conical opening at the top and a connecting cavity 11 at the bottom. The grinding cone 8 is slidably connected to a movable cover 12 through the connecting cavity 11. Pushing cylinders 42 are fixedly connected to the lower sides of the movable cover 12. Opening grooves 14 are opened on both sides of the grinding cone 8. The pushing cylinders 42 penetrate the groove wall of the opening grooves 14 and are slidably connected to the grinding cone 8.

[0038] Multiple discharge ports 43 are evenly spaced below the movable cover 12. Multiple sealing blocks 46 are fixedly connected to the grinding cone 8 inside the fixed ring 13. The sealing blocks 46 are fitted into the discharge ports 43. The movement of the movable cover 12 is guided and restricted by the connecting cavity 11 to prevent the movable cover 12 from tilting during movement. The fitting of the sealing blocks 46 into the discharge ports 43 can seal the discharge ports 43 to prevent the suspension from being accidentally discharged during the grinding process.

[0039] An electric push rod 15 is fixedly installed in the opening groove 14 on one side of the grinding cone 8, and a guide rod 16 is fixedly connected to the opening groove 14 on the other side of the grinding cone 8. The connecting cavity 11 is connected to the opening groove 14. The movable end of the electric push rod 15 is fixedly connected to one side of the movable cover 12. The guide rod 16 passes through the wall of the movable cover 12 and slides with the push cylinder 42 on one side of the movable cover 12. A connecting spring 59 is sleeved on the guide rod 16. One end of the connecting spring 59 is fixedly connected to the groove wall of the opening groove 14, and the other end of the connecting spring 59 is fixedly connected to the movable cover 12.

[0040] When the electric push rod 15 pushes and pulls the movable cover 12, the other side of the movable cover 12 maintains a sliding fit with the guide rod 16 through the push cylinder 42, thereby guiding the movable cover 12 through the guide rod 16 to ensure the smooth movement of the movable cover 12. During the process, the connecting spring 59 will be compressed and stretched, thereby playing an auxiliary role in resetting.

[0041] The downward-moving movable ring 52 can push the slide rod 49 through the inclined groove 53, causing the slide rod 49 to rotate along the transverse groove 47, thereby scraping the material. The downward-moving movable ring 52 can compress the return spring 51, and then the return spring 51 can push the movable ring 52 upward to reset after the push cylinder 42 moves away from the movable ring 52. At this time, the groove wall of the inclined groove 53 pushes the slide rod 49 in the opposite direction, causing the slide rod 49 to slide in the opposite direction along the transverse groove 47, thereby driving the connecting ring 48 and the scraper 50 to rotate in the opposite direction, forming a secondary scraping action opposite to the downward pressing process, so as to reduce the adhesion and residue of the material during the discharge process.

[0042] A protective shell 9 is fixedly connected to the upper part of the grinding cylinder 1, and a protective cover 10 is fixedly connected to the lower part of the protective shell 9. A mounting bracket 7 is fixedly connected to the upper part of the grinding cylinder 1, and a drive motor 17 is fixedly mounted on the mounting bracket 7. The output shaft of the drive motor 17 is connected to a connecting shaft 19. The connecting shaft 19 is rotatably connected to the grinding cylinder 1 and the protective shell 9 through bearings. A main gear 20 is fixedly connected to the connecting shaft 19, and a main bevel gear 21 is fixedly connected to one end of the connecting shaft 19. A secondary gear 22 is meshed with one side of the main gear 20. Both the main gear 20 and the secondary bevel gear 21 are located inside the protective shell 9. A rotating sleeve 23 is fixedly connected below 22. The rotating sleeve 23 is rotatably connected to the protective shell 9 through a bearing. A movable sleeve 24 is slidably sleeved on the rotating sleeve 23. The movable sleeve 24 passes through the protective cover 10 and is slidably connected to the protective cover 10. Limiting plates 57 are fixedly connected to the inner walls on both sides of the movable sleeve 24. Limiting grooves 58 are opened on both sides of the rotating sleeve 23. The limiting plates 57 and the limiting grooves 58 are slidably engaged. By sliding the limiting plates 57 in the limiting grooves 58, the movable sleeve 24 can be guided during its up and down movement, ensuring that the movable sleeve 24 can move smoothly when rotating and avoiding tilting or swaying.

[0043] A fixed cover 25 is fixedly connected to the lower part of the movable sleeve 24. An annular groove 26 is provided on the rotating sleeve 23. A connecting hoop 27 is rotatably connected in the annular groove 26 through a bearing. Multiple discharge ports 28 are provided at equal intervals on the fixed cover 25. A grinding cone roller 29 is fixedly connected to the lower part of the fixed cover 25. A through cavity 30 is provided in the grinding cone roller 29. A sliding cavity 31 is provided below the grinding cone roller 29. A fixed pipe 44 is fixedly connected to the upper part of the movable cover 12. Multiple feed ports 45 are provided at equal intervals on the fixed pipe 44. The fixed pipe 44 slides in the sliding cavity 31.

[0044] A temperature sensor 32 is fixedly installed on one side below the protective cover 10. A fixed frame 33 is fixedly connected inside the protective cover 10. A rotating roller 34 is connected to the protective cover 10 and the fixed frame 33 through a bearing. Fixed rods 35 are fixedly connected to both sides of the fixed frame 33. A movable frame 36 is slidably connected through the fixed rods 35. The movable frame 36 is U-shaped and has inclined top grooves 37 on both sides. I-shaped rods 60 are fixedly connected to both sides of the connecting hoop 27. The narrow part of the I-shaped rod 60 slides with the inclined top grooves 37, and the thick end of the I-shaped rod 60 abuts against the wall of the movable frame 36.

[0045] A fixed sleeve 38 is fixedly connected to the movable frame 36. A protrusion 39 is fixedly connected inside the fixed sleeve 38. The rotating roller 34 passes through the fixed sleeve 38 and slides with the fixed sleeve 38. An annular guide groove 40 is inclinedly opened on the rotating roller 34. The protrusion 39 slides in the annular guide groove 40. A secondary bevel gear 41 is fixedly connected to the rotating roller 34. The main bevel gear 21 and the secondary bevel gear 41 mesh with each other and are both set inside the protective cover 10.

[0046] As the rotating roller 34 rotates, the annular guide groove 40 pushes the protrusion 39, causing the fixed sleeve 38 to drive the movable frame 36 to slide back and forth. During this process, the movable frame 36 slides on the fixed rod 35, thereby limiting the movable frame 36 through the fixed rod 35 to prevent the movable frame 36 from moving or tilting. The contact between the thick end of the I-shaped rod 60 and the movable frame 36 allows the movable frame 36 to restrict the I-shaped rod 60 and the connecting hoop 27, preventing the connecting hoop 27 from twisting accidentally.

[0047] A working motor 18 is fixedly mounted on the mounting bracket 7 on one side of the drive motor 17. The output shaft of the working motor 18 is connected to a connecting rod 54. The connecting rod 54 is rotatably connected to the grinding cylinder 1 through a bearing. The connecting rod 54 passes through the secondary gear 22, the rotating sleeve 23 and the fixing cover 25 and is set in the through cavity 30. A conical disk 55 is fixedly connected to one end of the connecting rod 54. Multiple spiral blades 56 are fixedly connected at equal intervals on the conical disk 55.

[0048] The working motor 18 rotates the connecting rod 54 to make the conical disk 55 and the spiral blade 56 rotate at high speed. This causes the conical disk 55 to agitate and propel the suspending agent through the spiral blade 56, so that the suspending agent enters the fixed tube 44 through the feed port 45 and is propelled upward along the cavity 30 by the spiral blade 56. The suspending agent then flows out from the discharge port 28 on the fixed cover 25 and re-enters the grinding gap, realizing cyclic grinding and improving the grinding effect.

[0049] Working principle of this invention:

[0050] After the material is filled into the filling tube 5, the drive motor 17 and the working motor 18 are started. The drive motor 17 drives the main gear 20 and the main bevel gear 21 to rotate through the connecting shaft 19. The meshing of the main gear 20 and the auxiliary gear 22 causes the auxiliary gear 22 to drive the rotating sleeve 23 to rotate synchronously. Since the limiting plate 57 slides in the limiting groove 58, the rotating sleeve 23 can drive the movable sleeve 24 to rotate synchronously. The rotating movable sleeve 24 can drive the grinding cone roller 29 to rotate in the conical cavity of the grinding cone cylinder 8 through the fixed cover 25.

[0051] At the same time, the main bevel gear 21 and the secondary bevel gear 41 mesh and drive the rotary roller 34 to rotate around its own axis. During the process, the annular guide groove 40 inclined on the rotary roller 34 can push the protrusion 39, causing the fixed sleeve 38 and the movable frame 36 to slide back and forth along the fixed rod 35. When the movable frame 36 moves, the movable frame 36 can push the I-shaped rod 60 through the inclined groove wall of the inclined top groove 37, causing the I-shaped rod 60 to drive the connecting hoop 27 and the movable sleeve 24 to move up and down, thereby causing the grinding cone roller 29 to move back and forth while rotating, changing the grinding gap between the wall of the grinding cone roller 29 and the conical cavity wall of the grinding cone cylinder 8.

[0052] As the grinding cone roller 29 moves up and down, the fixed tube 44 can slide and extend within the sliding cavity 31, while the working motor 18 can rotate the connecting rod 54, causing the connecting rod 54 to drive the conical disk 55 and the spiral blade 56 to rotate at high speed. This causes the conical disk 55 to agitate and propel the ground suspension through the spiral blade 56, allowing the ground suspension to enter the fixed tube 44 through the feed port 45. The suspension is then propelled upward along the passage cavity 30 by the spiral blade 56, causing the suspension to flow out from the discharge port 28 on the fixed cover 25 and re-enter the grinding gap, forming a forced internal circulation grinding channel.

[0053] The suspending agent undergoes repeated extrusion and grinding between the grinding cone roller 29 and the grinding cone cylinder 8 until the particle size meets the process requirements. During the grinding process, the liquid pump 201 draws water from the cooling water tank 2 through the delivery pipe 204 and continuously delivers it to the cooling pipe 401. The water in the cooling pipe 401 absorbs the heat generated during the grinding process, and the temperature of the grinding area is monitored in real time by the temperature sensor 32. Finally, the water that has absorbed heat flows back to the cooling water tank 2 through the water inlet pipe 203 to cool down and restore its original temperature, forming a closed-loop heat exchange circuit.

[0054] After grinding is completed, the electric push rod 15 is activated, which pushes the movable cover 12 down, causing the discharge port 43 on the movable cover 12 to separate from the sealing block 46, thus forming a discharge channel. At this time, the finished suspension accumulated in the grinding cone 8 quickly passes through the discharge port 43 under the action of gravity and falls to the cone bottom of the grinding cylinder 1. When the discharge channel is fully opened, the push cylinder 42 abuts against the movable ring 52.

[0055] Then, the movable cover 12 is pushed down by the electric push rod 15, causing the push cylinder 42 to push the movable ring 52 down and compress the return spring 51. During the process, the movable ring 52 squeezes the slide rod 49 through the inclined groove 53, forcing the slide rod 49 to slide along the transverse groove 47 on the fixed ring 13, thereby driving the connecting ring 48 and the scraper 50 to rotate on the conical inner wall of the grinding cylinder 1, so that the scraper 50 scrapes off the sticky material to reduce the residue. The movable cover 12 is pushed and pulled back and forth within the moving stroke of the movable ring 52, thereby realizing the reciprocating scraping motion of the scraper 50.
