Description

Technical Field

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

[0002] Usually, heating is used to separate solid and liquid. The melting point of the solid is higher than the vaporization point of the liquid. The temperature of the solid-liquid mixture is heated to between the vaporization point of the liquid and the melting point of the solid, so that the liquid vaporizes and the solid and liquid are separated.

[0003] However, this method cannot be used in solid-liquid mixtures where the melting temperature of the solid is lower than the vaporization temperature of the liquid, because the solid has already melted and become sticky before the liquid is vaporized by the heating temperature. Therefore, only physical separation can be used. Using ordinary centrifuges, the separation effect is not ideal, and the solid-liquid mixture is easy to stick to the centrifuge wall.

[0004] Therefore, there is an ultra-gravity solid-liquid separator, such as the ultra-gravity device for solid-liquid separation mentioned in patent CN113413646A: it includes an ultra-gravity mixing part and an ultra-gravity separation part, the ultra-gravity mixing part includes a rotor assembly, the rotor assembly is used to mix and disperse the solid-liquid mixture, the ultra-gravity separation part includes a rotating assembly and a separation baffle, the rotating assembly includes a rotating shaft and a spiral centrifugal piece spirally surrounding the rotating shaft, the separation baffle is arranged to fit the outer edge of the spiral centrifugal piece, and a plurality of channels are formed on the surface of the separation baffle, and the pore size of the channel is smaller than the diameter of the solid material in the solid-liquid mixture. This patent uses super gravity technology to conduct intensive mixing of solid-liquid mixture in the super gravity mixing section, and then the super gravity separation section separates the solid-liquid mixture into solid and liquid, solving the problem of poor treatment results caused by uneven mixing of active agent solution and solid-liquid system in the current industrial solid-liquid treatment process. Through the setting of spiral centrifugal blades and separation baffles, not only the solid-liquid mixture has accelerated motion kinetic energy and then solid-liquid separation, but also the separated solid material is sent out of the device under the action of the spiral centrifugal blades. However, the separation efficiency and effect of this device are not ideal. Utility Model Content
