Embodiment 1

[0014] Embodiment 1: as figure 1 As shown, the food waste solid-liquid separation device is fed by the feeding cylinder 1, and then the material flows into the oil-water separator 2. There is a first valve 3 between the feeding cylinder and the oil-water separator 2, which is used to adjust the feed flow. The oil-water separator is provided with an oil decanter 4, an oil guide pipe 5 and a liquid level observer 6, and the oil decanter 4 is a thin plate drilled with uniform through holes. The liquid level of the material in the oil-water separator can be observed through the liquid level observer 6. When reaching a certain height, the grease floating on the liquid surface of the material surface is collected through the oil decanter 4 through the oil guide pipe 5. The rest of the material enters the solid-liquid separation drum 9 through the second valve 7 and the pipeline 8. The wall of the solid-liquid separation drum 9 is drilled with through holes, and a plurality of liftin...

Embodiment 2

[0015] Embodiment 2: It is composed of feeding cylinder 1, oil-water separator 2, solid-liquid separation drum 9, liquid storage tank 17, transmission device and other accessories, and uses the principle of connecting device and centrifugal principle to effectively separate food waste into oil and water and solid matter.

[0016] The oil-water separator 2 is a double-layer closed structure, the upper layer is provided with a horizontal oil decanter 4 and a liquid level observer 6, and grease is discharged through the oil decanter 4 through the oil guide pipe 5.

[0017] The oil decanter 4 in the oil-water separator 2 is a thin plate drilled with uniform through holes.

[0018] The solid-liquid separation drum 9 is a horizontal trumpet-shaped structure, the drum wall has uniform through holes, and a number of lifting plates are fixed on the inner wall.

[0019] The solid-liquid separation drum 9 can rotate at a high speed driven by the motor 12 and the second pulley 11 to dehy...

Abstract

The invention discloses a solid-liquid separating device for kitchen wastes, which is used for the preliminary treatment of the resource utilization of the kitchen wastes. The invention can effectively separate the kitchen wastes into oil, water and solid matters and can further carry out separate treatment and decrement transportation to shorten the dwell time of the kitchen wastes from production to collection, transportation and treatment, control contamination at a source, reduce the loss of raw materials caused by rottenness and deterioration, and reduce the environmental pollution. The solid-liquid separating device for the kitchen wastes is of a totally sealed structure; and a main component comprises a feeding cylinder, an oil-water separator, a solid-liquid separator, a liquid storage tank, a transmission device, and the like. The invention has the advantages of simple structure, convenient operation, little power consumption, and the like, can effectively achieve the intermediate dehydration and the oil removal of raw materials of the kitchen wastes, and satisfies the demands on the post-treatment and the utilization of solid materials, thereby effectively improving the efficiency of the further resource utilization of the kitchen wastes.

Description

technical field [0001] The invention relates to a pretreatment device for kitchen waste, in particular to a solid-liquid separation device for pretreatment of kitchen waste resource utilization. Background technique [0002] Food waste refers to waste such as food residues, residual liquids and waste oils generated during food processing, catering services, and catering. It is a relatively large part of urban waste, with large oil content, complex composition, and organic content Highly prominent features. Improper disposal of kitchen waste can easily cause severe environmental pollution. On the other hand, food waste is rich in nutrients and has great resource potential. There have been many studies on the resource treatment of food waste at home and abroad. However, due to the complex composition of food waste, especially the high oil content, the scientific pretreatment of food waste and the realization of solid-liquid separation and oil-water separation are still the k...
