Description

Technical Field

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

[0002] A solid-liquid separator is a device used to separate solids from liquids and has a wide range of applications. Its operating principles are primarily based on physical or chemical methods to separate solids and liquids. Common operating principles include the following: 1. Filtration: The pore size of a filter medium (such as a filter screen or filter cloth) is used to block solid particles while allowing liquids to pass through. When a solid-liquid mixture passes through the filter medium, the solid particles are retained by the filter medium, while the liquid flows out through the filter medium. 2. Centrifugation: The centrifugal force causes solids and liquids to move in different trajectories within the centrifugal field, achieving separation. When a solid-liquid mixture is placed in a high-speed centrifuge, the different densities of the solids and liquids result in different centrifugal forces acting on them. The higher density solid particles move toward the outer walls of the centrifuge under the influence of centrifugal force, while the lower density liquid flows toward the center of the centrifuge. 3. Sedimentation: The density difference between the solid and liquid causes solid particles to settle in the liquid under the influence of gravity or centrifugal force, achieving separation. Among them, the solid-liquid separation device adopts the centrifugal principle. Since the centrifugal motor is generally installed on the top of the device, after the solid-liquid separation, the solid is in the centrifugal cylinder and it is not very convenient to remove the solid. In view of the above problem, the present invention provides a solution. Utility Model Content

The bottom of the centrifugal cylinder 4 is provided with a bottom cylinder 12, which extends to the outside of the outer shell 1. The position where the bottom cylinder 12 contacts the outer shell 1 is sealed. A connecting rod 13 is inserted in the bottom cylinder 12, and the diameter of the connecting rod 13 is smaller than the inner diameter of the bottom cylinder 12. The upper end of the connecting rod 13 is provided with a sealing plug 11, and the bottom of the centrifugal cylinder 4 is provided with a sealing surface that fits and seals with the sealing plug 11. The bottom end of the connecting rod 13 is provided with a screw head 14, which is threadedly connected to the screw barrel 15. The rotating screw barrel 15 cooperates with the screw head 14 so that the upper end of the screw barrel 15 presses against the lower end of the bottom cylinder 12, so that the sealing plug 11 fits and seals with the sealing surface.

[0018] Furthermore, the lower end of the scraper plate 9 is fixedly connected to the inner wall of the shell 1 through a retaining rod 10. By providing the retaining rod 10, the stability of the scraper plate 9 during operation can be improved, so that it can maintain a better scraping effect.
