Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of nano-calcium carbonate preparation devices, specifically a cleaning device for the preparation of nano-calcium carbonate. Background Technology
[0002] Calcium carbonate is an inorganic compound and a major component of limestone, marble, and other minerals. It is essentially insoluble in water but soluble in hydrochloric acid. It is one of the most common substances on Earth, found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also a major component of the bones and shells of some animals. Calcium carbonate is an important building material with wide industrial applications.
[0003] According to a public notice (No. CN221790230U) of a cleaning device for calcium carbonate preparation, the above application describes a method that involves setting a rotatable rotating screen inside the device housing. When cleaning calcium carbonate raw materials, the calcium carbonate raw materials to be cleaned can be continuously placed into the rotating screen for cleaning. During the cleaning process, the drive motor drives the rotating screen to rotate. As the rotating screen rotates, the calcium carbonate raw materials inside will rub against the brush structure on the brushing device. At the same time, the rinsing device will spray cleaning water onto the calcium carbonate raw materials, thereby continuously brushing the calcium carbonate raw materials that have entered the rotating screen.
[0004] However, in actual use, the above-mentioned equipment only relies on the brush bristles on the roller to passively clean the workpiece, and cannot effectively and actively clean the workpiece. Moreover, the equipment cannot perform multiple cleaning operations on the workpiece, which greatly reduces the cleaning efficiency. In view of this, we propose a cleaning device for the preparation of nano-calcium carbonate. Utility Model Content
[0005] The purpose of this invention is to provide a cleaning device for the preparation of nano-calcium carbonate, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A cleaning device for the preparation of nano-calcium carbonate includes an outer cylinder, a fixing frame fixedly connected to the outer wall of the outer cylinder, a feeding port fixedly connected to one side of the outer cylinder, and a stirring mechanism provided on the other side of the outer cylinder, the stirring mechanism comprising:
[0007] The motor is fixedly connected to one side of the outer wall of the outer cylinder. The output end of the motor is fixedly connected to a drive shaft. A sun gear is fixedly connected to the outer surface of the drive shaft. Planet gears mesh with the outer surface of the sun gear. Gear rings mesh with the outer surface of the planet gears.
[0008] The device cylinder has an outer wall of the gear ring fixedly connected to the inner wall of the device cylinder, a circular groove is provided on the side of the device cylinder away from the motor, a fixed shaft is fixedly connected to the center of the planetary gear, and a cleaning cylinder is fixedly connected to the outer wall of the device cylinder away from the motor.
[0009] Preferably, a cleaning mechanism is provided on the outer surface of the fixed shaft. The cleaning mechanism includes a spiral spring, one end of which is fixedly connected to the outer surface of the fixed shaft, and the other end of which is fixedly connected to a rotating drum. Brush bristles are fixedly connected to the outer surface of the rotating drum.
[0010] Preferably, a water pump is fixedly connected to the side of the outer cylinder closest to the motor, a water supply pipe is fixedly connected to the output end of the water pump, a water distribution pipe is fixedly connected to the side of the water supply pipe away from the motor, a water passage pipe is fixedly connected to the end of the water distribution pipe away from the motor, and a nozzle is fixedly connected to the side of the water passage pipe away from the outer cylinder.
[0011] Preferably, the number of cleaning mechanisms is set to multiple sets, and the multiple sets of cleaning mechanisms are distributed in a circumferential array on the outer surface of the fixed shaft.
[0012] Preferably, the diameter of the cleaning cylinder is smaller than the diameter of the outer cylinder, and the diameter of the cleaning cylinder is the same as the diameter of the device cylinder.
[0013] Preferably, the water pipe and nozzle are disposed in the gap between the cleaning cylinder and the outer cylinder.
[0014] Preferably, the number of water pipes is provided in multiple sets, and the multiple sets of water pipes are distributed in a circumferential array on the side wall of the outer cylinder.
[0015] Compared with the prior art, this utility model provides a cleaning device for the preparation of nano-calcium carbonate, which has the following beneficial effects:
[0016] 1. This cleaning device for the preparation of nano-calcium carbonate employs a planetary gear system for its stirring mechanism. The sun gear is driven to rotate via a motor's drive shaft. The sun gear meshes with planetary gears, which in turn mesh with a gear ring fixed to the device cylinder. This achieves rotational motion of both the device cylinder and the cleaning cylinder. On one hand, the overall rotation of the cleaning cylinder provides macroscopic stirring force, ensuring uniform distribution of nano-calcium carbonate during the cleaning process. On the other hand, the rotation of the planetary gears adds microscopic turbulence and shear force, effectively breaking up particle agglomeration and improving cleaning efficiency. This structure not only enhances the uniformity and thoroughness of stirring but also reduces energy consumption, making it particularly suitable for the preparation of nanoscale materials and significantly improving cleaning effects and product quality.
[0017] 2. The cleaning device for the preparation of nano-calcium carbonate uses a spiral spring to connect a fixed shaft and a rotating drum, allowing the bristles on the rotating drum to flexibly oscillate or rotate. When the fixed shaft rotates with the planetary gears, the spiral spring stores and releases energy, driving the rotating drum and bristles to adaptively contact the surface of the cleaning drum. At the same time, multiple cleaning mechanisms are arranged in a circumferential array to ensure that the entire inner wall of the cleaning drum and the gap between the outer drum are fully covered. This design not only improves the flexibility and adaptability of cleaning, but also reduces equipment wear caused by hard friction. Combined with the water flow assistance of the nozzles, it can achieve efficient and thorough cleaning. Attached Figure Description

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a cleaning device for the preparation of nano-calcium carbonate, including an outer cylinder 1, a fixing frame 12 fixedly connected to the outer wall of the outer cylinder 1, a feeding port 11 fixedly connected to one side of the outer cylinder 1, and a stirring mechanism 2 provided on the other side of the outer cylinder 1. The stirring mechanism 2 includes: a motor 21, a transmission shaft 22, a sun gear 23, a planetary gear 24, a gear ring 25, a device cylinder 26, a cleaning cylinder 27, and a fixing shaft 28.
[0025] In one embodiment of this utility model, the motor 21 is fixedly connected to one side of the outer wall of the outer cylinder 1. A drive shaft 22 is fixedly connected to the output end of the motor 21. A sun gear 23 is fixedly connected to the outer surface of the drive shaft 22. A planet gear 24 meshes with the outer surface of the sun gear 23. A gear ring 25 meshes with the outer surface of the planet gear 24. The outer wall of the gear ring 25 is fixedly connected to the inner wall of the device cylinder 26. A circular groove is formed on the side of the device cylinder 26 away from the motor 21. A fixed shaft 28 is fixedly connected to the center of the planet gear 24. A cleaning cylinder 27 is fixedly connected to the outer wall of the device cylinder 26 away from the motor 21. The stirring mechanism 2 of this device adopts a planetary gear system, driven by the motor... The drive shaft 22 of 21 drives the sun gear 23 to rotate. The sun gear 23 meshes with the planet gear 24, and the planet gear 24 further meshes with the gear ring 25 fixed on the device cylinder 26, thereby realizing the rotational motion of the device cylinder 26 and the cleaning cylinder 27. On the one hand, the overall rotation of the cleaning cylinder 27 provides macroscopic stirring force to ensure that the nano-calcium carbonate is evenly distributed during the cleaning process. On the other hand, the rotation of the planet gear 24 adds microscopic turbulence and shear force, effectively breaking up particle agglomeration and improving cleaning efficiency. This structure not only enhances the uniformity and thoroughness of stirring, but also reduces energy consumption. It is particularly suitable for the preparation of nanoscale materials and can significantly improve the cleaning effect and product quality.
[0026] In addition, a cleaning mechanism 3 is provided on the outer surface of the fixed shaft 28. The cleaning mechanism 3 includes a spiral spring 31. One end of the spiral spring 31 is fixedly connected to the outer surface of the fixed shaft 28, and the other end of the spiral spring 31 is fixedly connected to a rotating drum 32. Brush bristles 33 are fixedly connected to the outer surface of the rotating drum 32. The cleaning mechanism 3 of this device uses the spiral spring 31 to connect the fixed shaft 28 and the rotating drum 32, so that the brush bristles 33 on the rotating drum 32 can perform flexible oscillation or rotational movement. When the fixed shaft 28 rotates with the planetary gear 24, the spiral spring 31 stores and releases energy, driving the rotating drum 32 and the brush bristles 33 to adaptively contact the surface of the cleaning drum 27. At the same time, multiple sets of cleaning mechanisms 3 are arranged in a circumferential array to ensure that the gap between the inner wall of the cleaning drum 27 and the outer drum 1 is fully covered. This design not only improves the flexibility and adaptability of cleaning, but also reduces the wear of equipment caused by hard friction. Combined with the water flow assistance of the nozzle 44, efficient and thorough cleaning can be achieved.
[0027] In this embodiment of the invention, a water pump 4 is fixedly connected to the side of the outer cylinder 1 closest to the motor 21. A water supply pipe 41 is fixedly connected to the output end of the water pump 4. A water distribution pipe 42 is fixedly connected to the side of the water supply pipe 41 furthest from the motor 21. A water passage pipe 43 is fixedly connected to the end of the water distribution pipe 42 furthest from the motor 21. A nozzle 44 is fixedly connected to the side of the water passage pipe 43 furthest from the outer cylinder 1. Multiple sets of cleaning mechanisms 3 are arranged in a circumferential array on the outer surface of the fixed shaft 28. The diameter of the cleaning cylinder 27 is smaller than the diameter of the outer cylinder 1, and the diameter of the cleaning cylinder 27 is smaller than that of the device cylinder. The diameters of the two tubes are the same. The water pipe 43 and the nozzle 44 are set in the gap between the cleaning tube 27 and the outer tube 1. There are multiple sets of water pipes 43, which are arranged in a circumferential array on the side wall of the outer tube 1. The water pump 4 is connected to an external water source through the inlet end. The water pump 4 itself supplies water into the water supply pipe 41, the water distribution pipe 42 and the water pipe 43. The nozzle 44 supplies water to the inside of the tube. The water pipes 43 are arranged in a circumferential array in the gap between the cleaning tube 27 and the outer tube 1, which can spray water into the cleaning tube 27 more evenly, so as to facilitate the cleaning of nano calcium carbonate.
[0028] In this invention, during use, the motor 21 drives the transmission shaft 22 and its sun gear 23 to rotate. The sun gear 23 drives the planet gears 24 meshing with it to rotate. The planet gears 24 then roll along the fixed gear ring 25 meshing with them, thereby driving the device cylinder 26 fixed to the outer wall of the gear ring 25 and the cleaning cylinder 27 connected to the side of the device cylinder 26 away from the motor 21 to revolve. At the same time, the fixed shaft 28 at the center of each planet gear 24 moves with the planet gear 24. The cleaning mechanism 3 is provided on the outer surface of the fixed shaft 28. One end of the spiral spring 31 rotates with the fixed shaft 28, and the other end of the rotating drum 32 connected to it rotates relative to the rotating drum 32 under the action of inertia and the spiral spring 31, causing the bristles 33 on its outer surface to brush the material in the cleaning drum 27. At the same time, the water pump 4 delivers the cleaning liquid through the water supply pipe 41 and the water distribution pipe 42 to multiple sets of water pipes 43 distributed in a circular array, and finally sprays it out from the nozzle 44 located in the gap between the cleaning drum 27 and the outer drum 1 to rinse the nano calcium carbonate in the cleaning drum 27. The material is added through the feeding port 11.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
