Description

Technical Field

[0001] This utility model belongs to the technical field of pulverizing mechanisms, specifically a high-efficiency and energy-saving pulverizing mechanism for producing high-purity potassium carbonate powder. Background Technology

[0002] High-efficiency and energy-saving pulverizing mechanisms for producing high-purity potassium carbonate powder typically employ an air jet mill as the core equipment. This mill utilizes high-pressure airflow to accelerate materials to supersonic speeds, achieving fine pulverization without metal contamination through particle collisions. Combined with low-temperature cooling technology (such as dry ice or liquid nitrogen pre-cooling), it enhances brittleness and reduces energy consumption. The mechanism ensures uniform particle size (D50 1-10μm) and purity exceeding 99.9% through intelligent grading control. It is widely used in high-end fields such as electronic semiconductors, optical glass, and pharmaceutical intermediates, meeting the stringent requirements for ultrafine, high-purity potassium carbonate. Simultaneously, it provides basic raw materials for the deep processing of potassium carbonate nanomaterials and special potassium salts, combining high efficiency, environmental friendliness, and economy.

[0003] Existing high-purity potassium carbonate powder pulverizing mechanisms are prone to causing powder to fly during feeding, which not only wastes raw materials and increases production costs, but also pollutes the working environment and endangers the respiratory health of workers. At the same time, the flying powder may settle on the surface of the equipment, affecting the accuracy and lifespan of the equipment, and may even cause safety hazards such as dust explosions. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a high-efficiency and energy-saving crushing mechanism for producing high-purity potassium carbonate powder. It effectively solves the problem that existing high-purity potassium carbonate powder crushing mechanisms are prone to powder flying during feeding, which not only wastes raw materials and increases production costs, but also pollutes the working environment and endangers the respiratory health of workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving pulverizing mechanism for producing high-purity potassium carbonate powder, comprising a screw conveyor, a connecting pipe fixedly installed at one end of the lower part of the screw conveyor, a pulverizing cylinder fixedly installed at the bottom of the connecting pipe, a feeding pipe fixedly installed at the bottom of the pulverizing cylinder, a storage cylinder fixedly installed at the bottom of the feeding pipe, a discharge valve fixedly installed at the bottom of the storage cylinder, a discharge pipe fixedly installed at the bottom of the discharge valve, a pulverizing component provided inside the pulverizing cylinder, a support frame fixedly installed on the surface of the discharge pipe, a servo motor fixedly installed at the lower part of the support frame, and a rotating dust suction component provided at the output end of the servo motor to effectively absorb dust generated during feeding.

[0006] Preferably, the crushing assembly includes a drive motor fixedly installed on one side of the crushing cylinder, the output end of the drive motor extending into the interior of the crushing cylinder and fixedly installed with a drive shaft, one end of the drive shaft being rotatably connected to the inner wall of the crushing cylinder, and a plurality of crushing blades being fixedly installed on the surface of the drive shaft.

[0007] Preferably, the rotary vacuum assembly includes a gear and a vacuum module fixedly installed at the output end of a servo motor. An external gear ring is meshed with one side of the gear, and a rotating ring is fixedly installed at the bottom of the external gear ring. A fixed ring is provided on the circumference of the rotating ring. Annular grooves are provided on both the upper and lower sides of the fixed ring. The rotating ring is slidably installed in the two annular grooves on the fixed ring. Three fixed brackets are fixedly installed on the upper part of the fixed ring. One end of each of the three fixed brackets is fixedly connected to a discharge pipe. Two slip rings are fixedly installed on the inner wall of the rotating ring. Two ring grooves are provided on the surface of the discharge pipe. The two slip rings are slidably installed inside the two ring grooves. Three vacuum hoppers are fixedly installed at the bottom of the rotating ring through three fixed pipes.

[0008] Preferably, the vacuuming module includes a vacuum cleaner fixedly installed on the surface of the storage cylinder, the bottom of the vacuum cleaner being fixedly connected to a fixing ring via a suction tube, and the bottom of the gear being rotatably connected to the suction tube via a shaft seat.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator puts the material into the screw conveyor, which transports the material to the connecting pipe and it falls into the crushing cylinder. At the same time, the drive motor drives several crushing blades to rotate through the drive shaft, thereby crushing the material. The crushing of the material by the drive motor driving the crushing blades is more energy-efficient than the traditional airflow crushing, thus achieving the effect of energy saving. The crushed potassium carbonate powder enters the storage cylinder through the feed pipe, and the operator can open the discharge valve to discharge the crushed potassium carbonate powder from the discharge pipe.

[0010] While discharging the material, the operator starts the servo motor to drive the gear to rotate. The gear drives the rotating ring to rotate through the external gear ring. When the rotating ring rotates, it drives two slip rings to slide along two ring grooves, improving the stability of the rotating ring. At the same time, the rotating ring also slides along two annular grooves on the fixed ring, improving the stability of the rotating ring. Since the rotating ring and the fixed ring are connected, the rotation of the rotating ring does not affect the connection between the fixed ring and the suction pipe. When the rotating ring rotates, it drives three dust collection buckets to rotate through three fixed pipes. At the same time, the vacuum cleaner operates. The vacuum cleaner sucks away the dust of powder during material discharge through the suction pipe, fixed ring, rotating ring, fixed pipes, and dust collection buckets. This ensures that the high-purity potassium carbonate powder pulverizing mechanism does not cause powder to fly during material discharge, avoids raw material waste, reduces production costs, and ensures the working environment and the respiratory health of workers.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

The crushing cylinder 3 is provided with a crushing component for crushing materials, and a servo motor 14 is fixedly installed on the surface of the discharge pipe 7 through a support frame 13. The output end of the servo motor 14 is provided with a rotating dust suction component to effectively absorb dust during material feeding.

[0022] The crushing assembly includes a drive motor 8 fixedly installed on one side of the crushing cylinder 3. The output end of the drive motor 8 extends into the interior of the crushing cylinder 3 and is fixedly installed with a drive shaft 11. One end of the drive shaft 11 is rotatably connected to the interior of the crushing cylinder 3 through a rotating seat, and a number of crushing blades 12 for rotating and crushing materials are fixedly installed on the surface of the drive shaft 11.

[0023] In use, the operator feeds the material into the screw conveyor 1, which transports the material to the connecting pipe 2 and into the crushing cylinder 3. At the same time, the drive motor 8 drives several crushing blades 12 to rotate through the drive shaft 11, thereby crushing the material. The crushing of the material by the drive motor 8 driving the crushing blades 12 is more energy-efficient than the traditional airflow crushing, thus achieving the effect of energy saving. The crushed potassium carbonate powder enters the storage cylinder 5 through the feed pipe 4. The operator opens the discharge valve 6 to discharge the crushed potassium carbonate powder from the discharge pipe 7.

[0024] While discharging the material, the operator starts the servo motor 14 to drive the rotating dust collection component to remove the dust generated during the material feeding process. This ensures that the high-purity potassium carbonate powder pulverizing mechanism does not cause powder to fly during material feeding, thus avoiding raw material waste, reducing production costs, and ensuring the health of the working environment and workers' respiratory system.

[0025] The rotary vacuum assembly includes a gear 15 fixedly mounted on the output end of a servo motor 14 and a vacuum module. An external gear ring 19 is meshed with one side of the gear 15. A rotating ring 18 is fixedly mounted on the bottom of the external gear ring 19. A fixed ring 17 is provided on the circumference of the rotating ring 18. Annular grooves 23 are provided on both the upper and lower sides of the fixed ring 17. The rotating ring 18 is slidably mounted in the two annular grooves 23 on the fixed ring 17. Three fixed brackets 20 are fixedly mounted on the upper part of the fixed ring 17. The interiors of the fixed ring 17 and the rotating ring 18 are connected. One end of each of the three fixed brackets 20 is fixedly connected to the discharge pipe 7. Two slip rings 24 are fixedly mounted on the inner wall of the rotating ring 18. Two ring grooves 25 are provided on the surface of the discharge pipe 7. The two slip rings 24 are slidably mounted inside the two ring grooves 25. Three vacuum hoppers 22 are fixedly mounted on the bottom of the rotating ring 18 through three fixed pipes 21. The three vacuum hoppers 22 are connected to the interior of the rotating ring 18 through the three fixed pipes 21.

[0026] The vacuuming module includes a vacuum cleaner 9 fixedly installed on the surface of the storage cylinder 5. The bottom of the vacuum cleaner 9 is fixedly connected to the fixing ring 17 through the suction tube 10. The fixing ring 17 communicates with the interior of the vacuum cleaner 9 through the suction tube 10. The bottom of the gear 15 is rotatably connected to the suction tube 10 through the bearing seat 16 to ensure the stability of the gear 15 when rotating.

[0027] While discharging the material, the operator starts the servo motor 14 to drive the gear 15 to rotate. The gear 15 drives the rotating ring 18 to rotate through the external gear ring 19. When the rotating ring 18 rotates, it drives the two slip rings 24 to slide along the two ring grooves 25, which improves the stability of the rotating ring 18 when rotating. At the same time, the rotating ring 18 also slides along the two annular sliding grooves 23 on the fixed ring 17, which improves the stability of the rotating ring 18 when rotating. Since the rotating ring 18 and the fixed ring 17 are connected, the rotation of the rotating ring 18 does not affect the connection between the fixed ring 17 and the suction pipe 10. When the rotating ring 18 rotates, it drives the three dust collection buckets 22 to rotate through the three fixed pipes 21. At the same time, it works in conjunction with the vacuum cleaner 9. The vacuum cleaner 9 sucks away the powder dust during the material discharge through the suction pipe 10, the fixed ring 17, the rotating ring 18, the fixed pipes 21, and the dust collection buckets 22.
