Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation, in particular to a centrifugal compound solid-liquid separation device. Background Art

[0002] Centrifugal solid-liquid separation is a process that uses centrifugal force to separate solid particles suspended in a liquid. Centrifugal solid-liquid separation equipment is widely used in industries such as chemical, food processing, biomedicine, water treatment and mineral processing. In these applications, the equipment may need to process mixtures with different physical and chemical properties, so the design and operating conditions of the centrifuge need to be adjusted according to the specific separation task.

[0003] A compound is a pure substance composed of two or more elements (as opposed to a simple substance). A compound has certain properties that are different from the elements or ions it contains, as well as from other compounds. It usually has a certain composition. Due to the properties of the compound itself, it needs to be separated and screened for solid-liquid separation when used, which requires the use of solid-liquid separation equipment.

[0004] When using existing compound solid-liquid separation equipment, all compound solutions are uniformly subjected to solid-liquid separation treatment, resulting in the inability to process a large amount of solution at one time, which limits the production scale and efficiency. At the same time, after solid-liquid separation, the solid material is not discharged by its own gravity, which prolongs the solid-liquid separation process and reduces the separation efficiency. Utility Model Content

[0005] In view of the above problems, the utility model discloses a centrifugal compound solid-liquid separation device.

[0006] The technical solution of the utility model is: a centrifugal compound solid-liquid separation device, comprising a separation body with an addition disk at the upper end, a plurality of solid-liquid separation cylinders connected to the addition disk through a connecting pipe, and a centrifugal separation assembly arranged in each of the solid-liquid separation cylinders;

[0007] The centrifugal separation assembly includes a centrifugal cylinder arranged in the solid-liquid separation cylinder and one side of which is penetrated to the outside through a connecting cylinder, a rotating gear ring arranged on the outer wall of the connecting cylinder, a driving gear meshed with the rotating gear ring, and a motor driving the driving gear to rotate; a discharge valve is arranged on the side wall of each solid-liquid separation cylinder and on the side opposite to the connecting cylinder, and the bottom end of each solid-liquid separation cylinder is connected to a slow flow temporary storage box through a connecting pipe.

[0008] Furthermore, a horizontal filter screen plate is provided inside the adding plate, and the horizontal filter screen plate is a detachable structure.

[0009] Note: The horizontal filter plate can be used to initially filter out larger solid residues in the compound mixed liquid to prevent larger solid residues from scratching or impacting the inner wall of the centrifuge cylinder, shortening the service life of the equipment and possibly affecting the separation efficiency. At the same time, the horizontal filter plate is set as a detachable structure to facilitate the removal and installation of the horizontal filter plate.

[0010] Furthermore, the solid-liquid separation cylinder is arranged at an angle, and a discharge pipe is provided at the lower end of the solid-liquid separation cylinder in the inclined direction, and the discharge valve is provided on the discharge pipe.

[0011] Description: The solid-liquid separation cylinder and the centrifugal cylinder are set to a downward inclined structure. The purpose is to use gravity to make the solid particles with higher density move more easily along the inclined surface to the wall of the centrifugal cylinder and deposit, thereby accelerating the separation process of solids and liquids. The separated solid matter is discharged through the automatic opening and closing of the discharge valve on the discharge pipe, reducing human participation and improving the degree of automation.

[0012] Furthermore, the bottom end of the slow-flow temporary storage box is connected to a distillation purification box through a slow-flow tube, the upper end of the distillation purification box is provided with a hollow snap-on cover, the upper end of the hollow snap-on cover is through-connected with the slow-flow tube, and the bottom end of the hollow snap-on cover is an inverted V-shaped structure, a plurality of spray holes are evenly arranged at the bottom end of the inner wall of the hollow snap-on cover, a heating plate is arranged on the inner wall of the distillation purification box, and the distillation purification box is connected to a condensation box through a connecting pipe.

[0013] Description: The liquid material after solid-liquid separation in the centrifugal cylinder is discharged into the slow-flow temporary storage box through the connecting pipe. At the same time, the slow-flow cylinder with a smaller diameter reduces the downward flow speed of the liquid material in the slow-flow temporary storage box. When the liquid material flows into the hollow buckle cover, the inverted V-shaped structure and the spray hole will evenly disperse the liquid material into the distillation purification box, and the liquid material will be heated by the heating plate, which can promote more uniform and rapid transfer of heat to the liquid, thereby accelerating the evaporation purification rate.

[0014] Furthermore, a support plate is provided at the bottom end of the outer wall of the separation main body, and a plurality of support legs are evenly provided at the bottom end of the support plate.

[0015] Note: The separation body is supported by supporting legs to avoid direct contact between the separation body and the ground, to prevent the bottom material of the separation body from being easily corroded by ground moisture or chemicals, and to extend the service life of the separation body.

[0016] Beneficial effects of the utility model:

[0017] The utility model discloses a centrifugal compound solid-liquid separation device. When in use, the compound solution to be separated into solid and liquid is dispersed into several centrifugal cylinders in equal amounts by adding a disc, and batch centrifugal solid-liquid separation is performed, so as to process a large amount of compound solution at the same time. Meanwhile, the inner wall of the centrifugal cylinder is sprayed with corrosion-resistant material, which can withstand the centrifugal force at high speed and possible corrosive liquid, so as to ensure the stable operation and separation efficiency of the device. The solid-liquid separation cylinder and the centrifugal cylinder are set as a downwardly inclined structure, so as to make it easier for the solid particles with larger density to move and deposit along the inclined surface to the cylinder wall of the centrifugal cylinder by gravity, thereby accelerating the separation process of solid and liquid. The liquid material after solid-liquid separation in the centrifugal cylinder is discharged into the slow flow temporary storage box through the connecting pipe. Meanwhile, the slow flow cylinder with smaller diameter reduces the downflow speed of the liquid material in the slow flow temporary storage box. After the liquid material flows into the interior of the hollow buckle cover, the liquid material is evenly dispersed into the distillation purification box through the inverted V-shaped structure and the spray hole, and the liquid material is heated by the heating plate, which can promote the heat to be transferred to the liquid more evenly and quickly, thereby accelerating the evaporation purification rate.
