Description

Kitchen waste dewatering mechanism and kitchen waste dewatering device

Technical Field

The invention relates to the technical field of garbage treatment, in particular to a kitchen garbage dewatering mechanism and a kitchen garbage dewatering device.

Background

The kitchen waste is complex in components and mainly comprises water, rice and flour food residues, peels, vegetables, animal and vegetable oil, fish, meat, bones, waste tableware, plastics, paper towels and other mixtures of various substances. The water content is high and can reach 80-95%.

The water contained in the kitchen waste mainly exists in two forms, one part is water which can be visually seen and is presented in a percolate form; the other part is not visually seen, or adsorbed in food residues such as rice and flour, or exists in cells of undeterified fruit and vegetable, fish, meat, bone, etc. components in the form of cell sap.

At present, in a pretreatment working section of the kitchen waste treatment industry, moisture in the kitchen waste is removed, and the process approach is generally as follows: through three procedures of sorting, crushing and dewatering, partial percolate and cell sap can be filtered out in the procedures of sorting and crushing; the dehydration step is usually carried out by using a screw extruder, a solid-liquid separator, or the like.

The working principle of the screw extruder and the solid-liquid separator is that materials are pushed along the axial direction through the rotation of a screw, and the volume ratio of the feeding and discharging materials in unit time of the equipment is changed by changing the screw pitch or the diameter of a screw or arranging a barrier (such as adding a filtrate mesh or a pressure regulating plate) at the outlet of the screw, so as to achieve the purpose of extrusion and dehydration. Because the components of the materials are complex and are mostly in loose contact with each other, the extrusion force between the components is small, and the components are not enough to extrude and remove water absorbed in food residues such as rice, flour and the like, especially cellular fluid in components such as non-putrefactive fruits and vegetables, fish, meat, bones and the like. The dehydration rate of the dehydration equipment is generally less than or equal to 10 percent, and the dehydration requirement of the kitchen waste treatment industry on the pretreatment working section cannot be completely met.

In addition, fixed axial gaps and radial gaps exist between the screw extruder and the screw blades of the solid-liquid separator and between the screw blades of the solid-liquid separator and the shell and between the screw blades of the solid-liquid separator and the filtrate hole mesh, so that the situation that hard objects such as metal pieces are often clamped into the axial gaps or the radial gaps to damage equipment cannot be avoided.

Therefore, how to improve the dehydration rate of the kitchen waste at the pretreatment working section, reduce the risk probability that hard objects such as metal pieces are clamped into the axial gap or the radial gap of the equipment, and avoid the damage to the equipment is a technical problem to be solved by technical personnel in the field.
