Description

Technical Field

[0001] This utility model belongs to the field of calcium carbonate preparation technology, and in particular relates to a calcium carbonate preparation filtration and separation device. Background Technology

[0002] Calcium carbonate is typically prepared using natural limestone (whose main component is calcium carbonate) or industrial byproducts as raw materials. The limestone is calcined at high temperatures to produce quicklime (calcium oxide, CaO) and carbon dioxide (CO2). The quicklime is then slaked in water to obtain a hydrated lime (calcium hydroxide, Ca(OH)2) emulsion. Carbon dioxide gas is then introduced into the calcium hydroxide solution, causing it to recarbonate and precipitate calcium carbonate. After post-processing steps such as filtration, washing, drying, and pulverization, light calcium carbonate is finally obtained, or heavy calcium carbonate can be produced under controlled conditions. This process is mature, uses abundant raw materials, and has low costs, making it widely used in plastics, rubber, papermaking, coatings, and pharmaceuticals.

[0003] For example, Chinese patent CN212631896U discloses a high-efficiency calcium carbonate slurry filtration and separation device, including a housing. A motor is fixedly connected to the top of the housing, and the output end of the motor is movably connected to the top of the housing via a bearing. A vertical rod is fixedly connected to the output end of the motor, and horizontal rods are fixedly connected to both sides of the vertical rod. This invention achieves high working efficiency and improves the utilization rate of calcium carbonate through the cooperation of horizontal rods, stirring blades, stirring rods, horizontal plates, through holes, and brush bristles. It effectively avoids the phenomenon of calcium carbonate not dissolving, not only improving working efficiency but also increasing the solubility of calcium carbonate. This prevents the phenomenon of calcium carbonate raw materials and impurities being filtered out together due to low solubility, thereby improving the utilization rate of calcium carbonate raw materials, meeting the needs of today's market, improving the practicality and usability of the filtration and separation device, and solving the problem of low working efficiency of previous filtration devices.

[0004] The above-mentioned patent has the following problems: in actual use, the filtration and separation effect is poor, it is not possible to fully separate calcium carbonate into solid and liquid, and it is not possible to quickly remove the separated filter cake, which increases the workload of the staff and is not conducive to the use of the staff. In view of this, we propose a calcium carbonate preparation filtration and separation device. Utility Model Content

Through the set rotating component, the rotating shaft can be driven to rotate, and the mounting shell rotates synchronously. The mounting block inserted inside drives the filter cartridge to rotate together. The surface of the filter cartridge is full of holes. At this time, the calcium carbonate slurry to be treated is added through the top of the box and fills the filter cartridge.

The mounting shell 6 at the top of the rotating shaft 5 rotates synchronously, and the mounting block 7 inserted inside it drives the filter cartridge 8 to rotate together. The surface of the filter cartridge 8 is full of holes. At this time, the calcium carbonate slurry to be treated is added through the top of the box 2 and filled into the filter cartridge 8. During the rotation of the filter cartridge 8, the liquid is separated through the holes and discharged through the water outlet pipe 17. By starting the hydraulic rod 10, the output end of the hydraulic rod 10 pushes the pressure plate 11 to move downward, squeezing the slurry or filter cake in the box 2, and further realizing solid-liquid separation.

[0056] After filtration is complete, close the solenoid valve 18 and stop the hydraulic rod 10. Open the door 3 using the rubber handle 4 on the door 3 hinged to one side of the housing 2. Since the rotating shaft 5 is mounted on the bottom of the inner wall of the housing 1, the position of the mounting shell 6 can be adjusted to a convenient location for operation. Pull the mounting block 7 at the bottom of the filter cartridge 8 out of the mounting shell 6 to separate the filter cartridge 8 from the rotating shaft 5, so that the filter cartridge 8 can be cleaned or replaced. When using it again, reinsert the mounting block 7 into the mounting shell 6, close the door 3, and repeat the above filtration and pressing process to continue working.
