In this embodiment, the slurry overflows from the overflow port 12 to the settling chamber 2, because the lower end of the inclined honeycomb tube 23 is inserted into the slurry surface, when the slurry touches the inclined surface of the inclined honeycomb tube 23, the slurry settles along the inclined surface of the inclined honeycomb tube 23 under the action of the inclined surface of the inclined honeycomb tube 23, so as to reduce the motion speed of the slurry, reduce the vibration of the slurry following the water, prevent the slurry from scattering into slurry blocks with small concentration due to the vibration, and prevent suspended impurities and water from staying on the horizontal surface, thereby increasing the adsorption area of the water and the suspended impurities, and achieving the effect of improving the solid-liquid separation quality.

As shown in FIG. 1, the inclined angle between the honeycomb inclined tube 23 and the horizontal plane is 45-60 degrees.

In this embodiment, the inclined honeycomb pipe 23 is arranged obliquely, when slurry overflows from the overflow port 12 to the settling chamber 2, the slurry is filled in the settling chamber 2 along the length direction of the settling chamber 2, the slurry flushes with the inclined surface of the inclined honeycomb pipe 23, the slurry slides downwards under the action of the inclined surface due to gravity, water and floating impurities stay on the horizontal surface, and the inclined angle of the inclined honeycomb pipe 23 is set to be 45-60 degrees, so that solid-liquid separation of the slurry is facilitated, and the effect of improving the solid-liquid separation efficiency of the slurry is achieved.
