Abstract

The invention discloses a kitchen waste liquid pretreatment device, and relates to the technical field of kitchen waste treatment. The kitchen waste liquid pretreatment device is used for solving the problem that the incineration cost of kitchen waste residues is increased due to the fact that the particle size of the waste residues is large and the water content of separated solid residues is relatively high in existing kitchen waste water front-end pretreatment. According to the kitchen waste liquid pretreatment device, a spiral extrusion filtering mechanism is additionally arranged, the separated solid residues automatically slide to the spiral extrusion filtering mechanism under the gravity, are slowly extruded, pass through a filter screen cylinder with a gap of 1mm, and are pushed into an upward solid-residue climbing guide pipe, the solid-residue climbing guide pipe is arranged obliquely upwards and forms an included angle of 120 degrees with a spiral extrusion in axial direction, the solid residues start to climb upwards in an extrusion channel, so that relatively large resistance is generated, spiral extrusion is more compact, water in the solid residues is effectively extruded out, the extruded waste liquid passes through a water bin at the bottom of the spiral extrusion and then flows into the bottom of a solid-liquid separation device, so that the water content of the solid residues can be reduced from 90% to about 50% in the solid residue extrusion link.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to a kitchen waste liquid pretreatment device. Background technique [0002] In the conventional sanitation waste transfer station, the kitchen waste treatment method is preliminary separation of solid and liquid. The large and medium-sized solid waste and waste liquid are separated, and the solid waste is then transferred to a thermal power plant for incineration. The separated waste liquid is heated for preliminary For oil-water separation, the waste residue with a particle size of 1 to 20mm accounts for about 20% of the waste liquid. The waste liquid cannot be directly processed by the biochemical system, and small particle size solid-liquid separation of the waste liquid and secondary oil-water after heating are required. Separation, solid-liquid separation, the separated solid slag is compressed, and the moisture content is controlled at about 50% before being t...
