Description

Technical Field

[0001] This utility model relates to the technical field of quantitative filling devices, and in particular to a quantitative filling device for potassium pyrophosphate packaging. Background Technology

[0002] Potassium pyrophosphate refers to the potassium salt of pyrophosphate. It is a representative phosphate in polyphosphate fertilizers, typically a group of phosphorus-containing compounds formed by the reaction of pyrophosphate with potassium hydroxide. The main use of potassium pyrophosphate is as a substitute for potassium cyanide in cyanide-free electroplating. With the increasing demand for potassium pyrophosphate, it is also used industrially in surface treatment, high-grade detergents, paints, cleaning agents, dispersants, and buffers. In the food industry, it is used as an emulsifier, texture improver, chelating agent, and quality improver. Traditional potassium pyrophosphate packaging and filling mostly relies on valves to control the material's discharge. However, because highly hygroscopic potassium pyrophosphate crystals tend to absorb moisture and clump together in the material box, the material accumulates at the bottom of the cone, causing blockages and intermittent discharge. This results in inconsistent material quantities in each bag. Therefore, a quantitative filling device for potassium pyrophosphate packaging that can break up clumps is needed. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a potassium pyrophosphate packaging quantitative filling device, which can solve the problem that the highly hygroscopic potassium pyrophosphate crystal particles easily absorb moisture and clump in the material box, causing the material to accumulate at the bottom of the cone, forming a blockage, and the material is discharged intermittently, resulting in different material amounts in each bag.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a potassium pyrophosphate packaging and quantitative filling device, comprising a filling cylinder, a filling frame fixedly connected to the surface of the filling cylinder, an inlet and an outlet opened on the surface of the filling cylinder, a guide tube slidably connected to the inner wall of the filling cylinder, a rack fixedly connected to the inner wall of the guide tube, a rotating disk fixedly connected to the bottom surface of the guide tube, a drain hole opened on the surface of the rotating disk, a fixing plate fixedly connected to the inner wall of the filling cylinder, a through hole opened on the surface of the fixing plate, a fixing block fixedly connected to the surface of the filling cylinder, a baffle slidably connected to the bottom surface of the filling cylinder, a pressure sensor fixedly connected to the surface of the baffle, and a dispersing device provided inside the filling cylinder.

[0005] Preferably, a motor and a second motor are fixedly connected to the surface of the filling cylinder, a gear is meshed with the surface of the rack, and the output end of the motor extends rotatably into the interior of the filling cylinder and is fixedly connected to the gear.

[0006] Preferably, the fixed plate is slidably connected to the rotating disk.

[0007] Preferably, the fixing block is L-shaped, and an electric push rod is fixedly connected to the surface of the fixing block. The output end of the electric push rod passes through the fixing block and is fixedly connected to the baffle.

[0008] Preferably, the leakage hole is connected to the through hole.

[0009] Preferably, the dispersing device includes a rotating shaft rotatably connected to the surface of a rotating disk. The output end of the second motor extends rotatably into the interior of the filling cylinder and is fixedly connected to the rotating shaft. Three stirring blades are fixedly connected to the surface of the rotating shaft. Dispersing holes are opened on the left surface of each of the three stirring blades, and dispersing teeth are fixedly connected to the right surface of each of the three stirring blades. A movable plate is fixedly connected to the surface of the rotating shaft and is slidably connected to the rotating disk. A groove is opened on the surface of the movable plate.

[0010] Preferably, the dispersing teeth can be cylindrical.

[0012] Preferably, the dispersing teeth can also be helical prism teeth.

[0013] Preferably, the pressure sensor is fixed to the side surface of the baffle facing the discharge port.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) The potassium pyrophosphate packaging quantitative filling device, through the setting of the dispersing device, when the filling operation is required, the second motor is started, and its output end drives the rotating shaft to rotate on the rotating disk surface. The rotating shaft drives the three stirring blades and the moving plate to rotate synchronously. During the rotation of the stirring blades, the moving plate rotates synchronously with the rotating shaft, which can scrape off the material attached to the rotating disk surface. The groove opened on the surface of the moving plate can break the clumps deposited at the bottom, ensuring that the leakage hole is unobstructed. The dispersing teeth on the right surface will mechanically break the clumps of potassium pyrophosphate, and the dispersing holes on the left surface will make the material form turbulence during stirring, further dispersing the small clumps, realizing the full dispersal of the material, avoiding the blockage of the material discharge due to the clumps of potassium pyrophosphate being damp, and preventing the material from being discharged intermittently, resulting in different material amounts in each bag.

Filling frame 2: The filling frame 2 is fixed on the surface of the filling cylinder 1. The function of the filling frame 2 is to support the filling cylinder 1 and the whole device, to ensure that the device is structurally stable when placed, and to provide a stable foundation for the filling operation. Motor 3: Motor 3 is fixed on the surface of filling cylinder 1. The output end of motor 3 extends into the interior of filling cylinder 1 and is fixed with gear 23. The function of motor 3 is to provide power. When motor 3 runs, it drives gear 23 to rotate. Through the meshing of rack 8, it drives guide tube 13 and rotating disk 16 to rotate, adjusting the overlapping area of ​​through hole 22 and leakage hole 18. Pressure sensor 4: Pressure sensor 4 is fixed on the surface of baffle 21. Pressure sensor 4 monitors the weight of the material in the packaging container in real time. When the weight reaches the preset threshold, it sends a signal to the control system to achieve precise control of quantitative filling. Inlet 5: Inlet 5 is located on the surface of filling cylinder 1. Inlet 5 is used to feed in potassium pyrophosphate material to be filled, providing a channel for the material to enter the filling cylinder 1 and ensuring that the material falls smoothly into the guide pipe 13. Second motor 6: The second motor 6 is fixed on the surface of the filling cylinder 1. The output end of the second motor 6 extends into the interior of the filling cylinder 1 and is fixed to the rotating shaft 9. The function of the second motor 6 is to provide dispersing power. When the second motor 6 is running, it drives the rotating shaft 9, stirring blades 10 and moving plate 14 to rotate, thereby dispersing the material. Electric push rod 7: The electric push rod 7 is fixed on the surface of the fixed block 20. The output end of the electric push rod 7 passes through the fixed block 20 and is fixed to the baffle 21. The electric push rod 7 drives the baffle 21 to slide through extension and retraction, thereby opening and blocking the discharge port 19, in conjunction with the quantitative filling process. Rack 8: Rack 8 is fixedly connected to the inner wall of the guide tube 13. Rack 8 meshes with gear 23. Rack 8 transmits the rotational power of gear 23, which drives the guide tube 13 to rotate along the inner wall of the filling cylinder 1, thereby driving the rotating disk 16 to rotate. Rotary shaft 9: Rotary shaft 9 is rotatably connected to the surface of rotating disk 16. Rotary shaft 9 is fixed to the output end of second motor 6. Stirring blade 10 and moving plate 14 are fixedly connected to the surface of rotating shaft 9. Rotary shaft 9 rotates under the drive of second motor 6, driving stirring blade 10 and moving plate 14 to run synchronously, providing power for the dispersing device. Stirring blades 10: There are three in total. The stirring blades 10 are fixed on the surface of the rotating shaft 9. The left surface of the stirring blades 10 has a dispersing hole 12 and the right surface is fixedly connected to a dispersing tooth 11. When the stirring blades 10 rotate, they stir the material. The dispersing tooth 11 breaks up the agglomerates, and the dispersing hole 12 forms turbulent dispersion of the material, so as to achieve full dispersal. Dispersing teeth 11: There are three in total. The dispersing teeth 11 are fixed on the right surface of the stirring blade 10. The dispersing teeth 11 rotate with the stirring blade 10 to mechanically break up the clumps of potassium pyrophosphate and prevent the material from clumping and affecting the feeding. Dispersing holes 12: Dispersing holes 12 are formed on the left surface of the stirring blade 10. Dispersing holes 12 make the material form turbulence during stirring, further disperse small lumps, and improve the uniformity of material dispersion. The guide tube 13 is slidably connected to the inner wall of the filling cylinder 1. The rack 8 is fixedly connected to the inner wall of the guide tube 13. The bottom surface of the guide tube 13 is fixedly connected to the rotating disk 16. The guide tube 13 is used to guide the material to fall above the rotating disk 16, and at the same time, it drives the rotating disk 16 to rotate under the drive of the gear 23. Moving plate 14: The moving plate 14 is fixed on the surface of the rotating shaft 9. The moving plate 14 is slidably connected to the rotating disk 16. A groove 15 is opened on the surface of the moving plate 14. The moving plate 14 rotates with the rotating shaft 9 to scrape off the material attached to the surface of the rotating disk 16. The groove 15 breaks up the clumps deposited at the bottom to ensure that the leakage hole 18 is unobstructed. Groove 15: Groove 15 is formed on the surface of the moving plate 14. Groove 15 rotates with the moving plate 14 to break up the material clumps deposited at the bottom of the rotating disk 16, prevent clumps from blocking the leakage hole 18, and ensure smooth material feeding. Rotary disk 16: Rotary disk 16 is fixedly connected to the bottom surface of guide tube 13. Rotary disk 16 is slidably connected to fixed plate 17. Drain hole 18 is opened on the surface of rotary disk 16. When rotary disk 16 rotates, it changes the overlapping area of ​​through hole 22 and drain hole 18 to control the amount of material falling and realize quantitative filling. Fixed plate 17: Fixed plate 17 is fixedly connected to the inner wall of filling cylinder 1. Fixed plate 17 is slidably connected to rotating disk 16. Through hole 22 is opened on the surface of fixed plate 17. Fixed plate 17 provides sliding support for rotating disk 16. Leak hole 18 cooperates with through hole 22 to guide material to fall accurately to discharge port 19. Leakage hole 18: Leakage hole 18 is formed on the surface of rotating disk 16. Leakage hole 18 is connected to through hole 22. Leakage hole 18 provides a falling channel for materials. By changing the overlapping area with through hole 22, the falling speed and total amount of materials are controlled. Discharge port 19: The discharge port 19 is located on the surface of the filling cylinder 1. The discharge port 19 is adapted to the baffle 21. The discharge port 19 is used to discharge a certain amount of potassium pyrophosphate material, so that the material falls into the packaging container below to complete the filling. Fixed block 20: Fixed block 20 is fixedly connected to the surface of filling cylinder 1. Fixed block 20 is "L" shaped. Electric push rod 7 is fixedly connected to the surface of fixed block 20. Fixed block 20 provides stable installation support for electric push rod 7, ensuring that electric push rod 7 drives baffle 21 to slide smoothly. Baffle 21: Baffle 21 is slidably connected to the bottom surface of filling cylinder 1. Baffle 21 is fixed to the output end of electric push rod 7. Baffle 21 is adapted to discharge port 19. Pressure sensor 4 is fixedly connected to the surface of baffle 21. Baffle 21 achieves the blocking and opening of discharge port 19 by sliding, and completes quantitative monitoring in conjunction with pressure sensor 4. Through hole 22: Through hole 22 is formed on the surface of fixed plate 17. Through hole 22 is connected to leakage hole 18. Through hole 22 adjusts the amount of material falling by changing the overlapping area with leakage hole 18 to ensure accurate filling quantity. Gear 23: Gear 23 is fixedly connected to the output end of motor 3. Gear 23 meshes with rack 8 on the inner wall of guide tube 13. When gear 23 rotates, it transmits power, driving rack 8 and guide tube 13 to rotate, providing power for the angle adjustment of rotating disk 16.

[0023] Example 1: Please see Figure 1-6The dispersing teeth 11 can be cylindrical. When using this potassium pyrophosphate packaging quantitative filling device, the feed port 5 on the surface of the filling cylinder 1 is opened, and the potassium pyrophosphate material to be filled is put in. The material falls into the inside of the guide tube 13 through the feed port 5 and accumulates above the rotating disk 16. The output end of the motor 3 rotates and extends into the inside of the filling cylinder 1, driving the gear 23 to rotate synchronously. Since the rack 8 meshes with the gear 23, and the guide tube 13 is slidably connected to the inner wall of the filling cylinder 1, the rotation of the gear 23 will cause the guide tube 13 to rotate along the inner wall, driving the rotating disk 16 at the bottom to rotate, so that the leakage hole 18 of the rotating disk 16 is initially aligned with the through hole 22 of the fixed plate 17. When the rotating disk 16 rotates, the overlapping area of ​​the leakage hole 18 on the surface and the through hole 22 of the fixed plate 17 changes. When the required amount of potassium pyrophosphate to be filled is not reached, the rotating disk 16 is moved so that the leakage hole 18 on the surface completely covers the through hole 22, and the required amount of potassium pyrophosphate to be filled reaches the quantitative limit. When the rotating disk 16 is moved, the un-perforated part of the surface completely blocks the through hole 22. The electric push rod 7 is activated, and its telescopic end extends to drive the baffle 21 to slide along the bottom surface of the filling cylinder, blocking the outlet 19. Under the action of gravity, potassium pyrophosphate is temporarily stored under the fixed plate 17. The temporarily stored potassium pyrophosphate falls onto the pressure sensor 4 of the baffle 21 below the outlet 19. The pressure sensor 4 monitors the weight of the container in real time and feeds back a signal. As the material continues to fall into the container, the weight monitored by the pressure sensor 4 gradually approaches the preset threshold. When the weight reaches the threshold, the pressure sensor 4 immediately sends a signal to the control system. The control system responds quickly, starts the motor 3 and closes the electric push rod 7. The motor 3 rotates, and the rotating disk 16 is moved to completely block the through hole 22. The telescopic end of the electric push rod 7 retracts, driving the baffle 21 to slide and open the outlet 19. The temporarily stored potassium pyrophosphate falls into the packaging container through the outlet 19, completing one quantitative filling. With the addition of the dispersing device, when filling is required, the second motor 6 is started, and its output end drives the rotating shaft 9 to rotate on the surface of the rotating disk 16. The rotating shaft 9 synchronously drives the three stirring blades 10 and the moving plate 14 to rotate. During the rotation of the stirring blades, the moving plate 14 rotates synchronously with the rotating shaft 9, which can scrape off the material attached to the surface of the rotating disk 16. The grooves 15 on the surface of the moving plate 14 can break up the clumps deposited at the bottom, ensuring that the drain hole 18 is unobstructed. The dispersing teeth 11 on the right surface will mechanically break up the clumps of potassium pyrophosphate, while the dispersing holes 12 on the left surface will cause the material to form turbulence during stirring, further dispersing the small clumps and achieving full dispersal of the material. This avoids the blockage of the material discharge due to the potassium pyrophosphate becoming damp and clumping, and prevents the material from being discharged intermittently, resulting in different amounts of material in each bag.

[0024] Example 2: Please see Figure 7The dispersing tooth 11 can also be a comb-shaped multi-branched tooth. When potassium pyrophosphate is freshly produced or the humidity of the workshop environment is low, the potassium pyrophosphate has not completely absorbed moisture and only slightly agglomerates. The multi-branched round head only breaks up large clumps without destroying small particle agglomerates, resulting in a small amount of fine powder. The branched teeth can contact multiple dispersed clumps at the same time, and the dispersing uniformity is better than that of a single tooth.

[0025] Example 3: Please see Figure 8 The dispersing teeth 11 can also be spiral ridge teeth. When the humidity of the workshop environment is high, the humidity of the material is also high. After potassium pyrophosphate absorbs moisture, it adheres to the teeth. When the spiral ridge structure rotates, it generates centrifugal force, which can actively throw off the adhered material and prevent potassium pyrophosphate from adhering to the teeth after absorbing moisture. The spiral ridge not only breaks up the clumps, but also drives the surrounding material to form local turbulence. Combined with the dispersing holes 12 of the stirring blades, it improves the overall dispersing uniformity.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
