Description

Technical Field

[0001] This utility model belongs to the technical field of wet grinding ultrafine heavy calcium carbonate processing equipment, and particularly relates to a dehumidification device for wet grinding ultrafine heavy calcium carbonate. Background Technology

[0002] Wet milling of ultrafine heavy calcium carbonate is an important process for the deep processing of heavy calcium carbonate. The core technology utilizes a liquid (mostly water, often with the addition of dispersants) as the grinding medium. Coarse heavy calcium carbonate particles (e.g., tens of micrometers in diameter) are subjected to thorough collision and shearing with the grinding medium (e.g., zirconium beads) in grinding equipment (such as sand mills or ball mills), ultimately processing them into ultrafine powders with particle sizes in the micrometer or even nanometer range. The presence of the liquid medium effectively suppresses dust generation during the grinding process, reducing environmental pollution. Simultaneously, the dispersant prevents the agglomeration of ultrafine particles, ensuring uniform particle size and narrow particle size distribution. The processed product is typically in slurry form and requires subsequent dehydration and drying processes to transform it into a solid powder. This process is widely applicable to fields such as coatings, papermaking, and plastics, which require high powder fineness and purity, offering advantages in both environmental friendliness and product quality stability.

[0003] After wet grinding of ultrafine heavy calcium carbonate, it needs to be dried. However, the material has a high moisture content after processing, and direct drying takes a long time, resulting in high time and energy costs. This leads to the problem that the direct drying efficiency of conventional wet grinding of ultrafine heavy calcium carbonate is relatively low.

[0004] To address these issues, we propose a dehumidification device for wet grinding of ultrafine heavy calcium carbonate. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low efficiency in direct drying of conventional wet grinding of ultrafine heavy calcium carbonate, and to propose a dehumidification device for wet grinding of ultrafine heavy calcium carbonate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dehumidification device for wet grinding of ultrafine heavy calcium carbonate includes a motor, a frame fixedly mounted externally to the motor, a guide hopper fixedly connected to the upper part of the frame, a vibrator fixedly connected to the upper part of the frame, and a centrifuge cylinder rotatably mounted on the upper part of the frame. A baffle is fixedly connected inside the centrifuge cylinder, and a rotating rod is fixedly connected to one end of the baffle. The lower end of the rotating rod is fixedly connected to the output shaft of the motor. The motor drives the rotating rod to rotate, which in turn drives the baffle to rotate, which in turn drives the centrifuge cylinder to rotate. Material is placed into the centrifuge cylinder, and the centrifuge cylinder and baffle cause the material to rotate at high speed, rapidly separating water from solids. The rotation speed is reduced so that the centrifugal force of the water is insufficient to allow it to flow into the guide hopper and be discharged through the guide hopper. The motor is then turned off, and the vibrator is driven to vibrate the frame. The frame acts on the centrifuge cylinder, causing the material inside the centrifuge cylinder to fall into the guide hopper and be discharged through the guide hopper, facilitating rapid dehydration and subsequent drying of the ultrafine heavy calcium carbonate.

[0007] Preferably, a guide cover is fixedly connected to the rotating rod, and the lower part of the baffle is fixedly connected to the guide cover. The guide cover blocks the lower part of the centrifuge cylinder, preventing material from directly passing through the centrifuge cylinder.

[0008] Preferably, the frame includes a frame body, with a base fixedly connected to the lower end of the frame body, and guide wheels rotatably mounted on the upper end of the frame body. The guide wheels are used to support the centrifuge cylinder, ensuring its stability.

[0009] Preferably, the feed hopper includes a hopper body, and a discharge nozzle is fixedly connected to the lower part of the hopper body. The internal spaces of the hopper body and the discharge nozzle are interconnected. When material or water falls into the hopper body, water is drained or material is discharged outward through the hopper body and the discharge nozzle.

[0010] Preferably, the centrifuge cylinder includes a cylinder body, and a collecting hopper is fixedly connected to the lower part of the cylinder body, with the lower part of the collecting hopper located directly above the hopper body. The collecting hopper guides materials or water into the hopper body.

[0011] Preferably, the centrifuge cylinder includes a retaining ring, which is fixedly connected to the upper part of the cylinder body. The retaining ring is used to block the material from being thrown out along the upper side of the cylinder body.

[0012] In summary, the technical effects and advantages of this utility model are as follows: The system utilizes a motor to drive a rotating rod, which in turn drives a baffle plate, which in turn drives a centrifuge drum. Material is placed inside the centrifuge drum, and the high-speed rotation of the drum and baffle plate causes rapid separation of water and solids. The rotation speed is then reduced to reduce the centrifugal force of the water, allowing it to flow into the guide hopper and be discharged. The motor is then turned off, and a vibrator is activated to vibrate the frame. This vibration, acting on the centrifuge drum, causes the material inside to fall into the guide hopper and be discharged. This process facilitates the rapid dehydration and subsequent drying of ultrafine heavy calcium carbonate. Attached Figure Description

[0016] like Figure 1 As shown, a dehumidification device for wet grinding of ultrafine heavy calcium carbonate includes a motor 1, a frame 2 fixedly mounted externally to the motor 1, a guide hopper 3 fixedly connected to the upper part of the frame 2, a vibrator 8 fixedly connected to the upper part of the frame 2, and a centrifuge cylinder 4 rotatably mounted on the upper part of the frame 2. A baffle 6 is fixedly connected inside the centrifuge cylinder 4, and a rotating rod 7 is fixedly connected to one end of the baffle 6. The lower end of the rotating rod 7 is fixedly connected to the output shaft of the motor 1. The motor 1 drives the rotating rod 7 to rotate, which in turn drives the baffle 6 to rotate, which in turn drives the centrifuge cylinder 4 to rotate. Material is placed into the centrifuge cylinder 4, and the centrifuge cylinder 4 and baffle 6 cause the material to rotate at high speed, rapidly separating water from solids. The rotation speed is reduced so that the centrifugal force of the water is insufficient to flow into the guide hopper 3 and discharge it. The motor 1 is then turned off, and the vibrator 8 is driven to vibrate the frame 2. The frame 2 acts on the centrifuge cylinder 4, causing the material inside the centrifuge cylinder 4 to fall into the guide hopper 3 and be discharged.

[0017] like Figure 1 As shown, a guide cover 5 is fixedly connected to the rotating rod 7, and the lower part of the baffle 6 is fixedly connected to the guide cover 5. The guide cover 5 is used to block the lower part of the centrifuge cylinder 4 to prevent the material from passing directly through the centrifuge cylinder 4.

[0018] like Figure 1 and 2 As shown, the frame 2 includes a frame body 21, with a base 23 fixedly connected to the lower end of the frame body 21, and guide wheels 22 rotatably mounted on the upper end of the frame body 21. The guide wheels 22 are used to support the centrifuge cylinder 4, ensuring the stability of the centrifuge cylinder 4.

[0019] like Figure 1 and 3 As shown, the feed hopper 3 includes a hopper body 31, and a discharge nozzle 32 is fixedly connected to the lower part of the hopper body 31. The internal spaces of the hopper body 31 and the discharge nozzle 32 are connected. When material or water falls into the hopper body 31, water is drained or material is discharged outward through the hopper body 31 and the discharge nozzle 32.

[0020] like Figure 1 , 3 As shown in Figure 4, the centrifuge cylinder 4 includes a cylinder body 41, and a collecting hopper 43 is fixedly connected to the lower part of the cylinder body 41. The lower part of the collecting hopper 43 is located directly above the hopper body 31. The collecting hopper 43 guides materials or water into the hopper body 31.

[0021] like Figure 1 and 4 As shown, the centrifuge cylinder 4 includes a retaining ring 42, which is fixedly connected to the upper part of the cylinder body 41. The retaining ring 42 is used to block the material from being thrown out along the upper side of the cylinder body 41.

[0022] Working principle: The motor 1 drives the rotating rod 7 to rotate, which in turn drives the baffle 6 to rotate, which in turn drives the centrifuge cylinder 4 to rotate. The material is put into the centrifuge cylinder 4, and the centrifuge cylinder 4 and the baffle 6 drive the material to rotate at high speed, so that the water is quickly separated from the solid. The rotation speed is reduced so that the centrifugal force of the water is insufficient to flow into the guide hopper 3 and is discharged through the guide hopper 3. The motor 1 is turned off, and the vibrator 8 drives the frame 2 to vibrate. The frame 2 acts on the centrifuge cylinder 4, causing the material in the centrifuge cylinder 4 to fall into the guide hopper 3 and be discharged through the guide hopper 3.
