Embodiment 1

[0040] Such as Figure 1~3 As shown, a food waste pretreatment system capable of efficiently recovering organic matter includes a crushing device 100, a desanding device 200, a first squeezing device 400, a crushing slag crushing device 600, and a second squeezing device 800 arranged in sequence; The discharge port of the crushing device 100 communicates with the feed port of the sand removal device 200, and the discharge port 231 of the sand removal device 200 communicates with the feed port 401 of the first squeezing device 400 through the screw pump 300. The slag outlet 403 and the liquid outlet 402 of a squeezing device 400 communicate with the slag inlet 601 and the liquid inlet 602 of the squeezed slag rolling device 600 respectively, and the discharge port 603 of the squeezed slag rolling device passes through the screw pump 700 It communicates with the feed port 801 of the second squeezing device; the crushed slag rolling device 600 is provided with a residue rolling c...

Embodiment 2

[0048] This embodiment is similar to Embodiment 1, the difference is that, as Figure 4~9 As shown, this embodiment is similar to Embodiment 1, the difference is that it also includes an unloading device 500 matched with the crushing device, and the unloading device 500 includes a transportation mechanism 510 that can carry the kitchen waste bin, and can The pneumatic clamping mechanism 520 for clamping the kitchen garbage can (the kitchen garbage is stored in the garbage can 501), and the mechanism that drives the pneumatic clamping mechanism 520 to rise and dump the kitchen garbage in the garbage can into the feed port of the crushing device Lifting mechanism 530 .

[0049] The conveying mechanism 510 includes a plurality of rollers 511 arranged alternately, and a pair of conveying belts 512 arranged symmetrically above the rollers, and the conveying belts 512 are driven by a motor 513 . The trash can 301 containing kitchen waste is located between the conveyor belts 312, a...

Abstract

The invention discloses a kitchen waste pretreatment system. The system comprises a crushing device, a desanding device, a first squeezing device, a squeezing residue rolling device and a second squeezing device which are sequentially arranged, wherein the squeezing residue rolling device is provided with a residue rolling chamber and a stirring chamber communicating with the residue rolling chamber; the residue rolling chamber is provided with a rolling mechanism; a residue inlet of the squeezing residue rolling device is arranged on the residue rolling chamber, so that residues entering thesqueezing residue rolling device from the residue inlet of the squeezing residue rolling device enter the stirring chamber after passing through the rolling mechanism; the stirring chamber is providedwith a stirring mechanism; and a liquid inlet and a discharging port of the squeezing residue rolling device are arranged on the stirring chamber, so that the residues passing through the rolling mechanism are mixed with a squeezing liquid and then are discharged. According to the kitchen waste pretreatment system, the residues subjected to the first squeezing are subjected to rolling treatment,and then are mixed with the squeezing liquid, so that more organic matters in the residues are dissolved into the liquid phase and the organic matters can be efficiently recovered during the second squeezing process.

Description

technical field [0001] The present application relates to the treatment of kitchen waste, in particular to a kitchen waste pretreatment system capable of efficiently recovering organic matter. Background technique [0002] Food waste mainly refers to the waste generated in the daily life of residents and other activities such as food processing, catering services, and unit meals. Food waste is rich in nutrients, mainly including starch, free sugar, protein, fat, cellulose and inorganic salts. Therefore, food waste is extremely easy to deteriorate and rot, which not only produces a large amount of toxins, emits foul-smelling gases, but also pollutes water bodies and the atmosphere. Diseases endanger people's daily life and health. [0003] With the advancement of technology, as far as the current situation is concerned, there are mainly the following ways to deal with kitchen waste: [0004] 1. Fertilization treatment: Fertilization treatment of kitchen waste mainly includ...
