Solid-liquid separation device

Abstract

The invention provides a solid-liquid separation device which comprises a shell, wherein a feed hopper is arranged at the upper part of the shell, a sleeve is sleeved with an opening in the bottom of the feed hopper and comprises an inner sleeve and an outer sleeve, an inner sleeve wall of the inner sleeve takes the shape of an inverted circular truncated cone, meshes opening are formed in the inner sleeve wall, a rotating shaft is arranged at the bottom of the inner sleeve, a drainage outlet is formed in the bottom of the outer sleeve, a gap space is reserved between the outer sleeve and the inner wall of the shell, and a solid receiving hopper communicated with the gap space is arranged below the sleeve at the bottom of the shell. Due to the separation device rotating at variable speeds, the liquid part in the kitchen waste passes through the mesh openings in the inner wall of the inner sleeve, is thrown to the gap space between the outer sleeve and the inner sleeve, and is recovered through a pipeline connected with the drainage outlet of the outer sleeve, the solid part is pushed away from the inner sleeve under the centrifugal effect, enters the gap space between the outer sleeve and the shell, then enters the solid receiving hopper below the gap, and is discharged from a discharge opening of the solid receiving hopper. Therefore, the soli and the liquid of the kitchen waste are separated, respectively recycled and differently treated.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a solid-liquid separation device. Background technique [0002] For the treatment of kitchen and garden fruit and vegetable waste, solid-liquid separation treatment must be carried out first. The methods currently used mainly include screw extrusion and vertical centrifugal drying. [0003] The screw extrusion method is to squeeze the garbage through a spiral pipe to separate the liquid part, thereby realizing the solid-liquid separation of the garbage. However, it is difficult to separate the extruded objects after extrusion dehydration. The vertical centrifugal drying method requires secondary cleaning of the thrown out garbage. [0004] How to separate the solid-liquid from the kitchen and garden fruit and vegetable waste, and how to automatically recycle the separated waste is an urgent problem to be solved. Contents of the invention [0005] In order to solve t...
