AI Technical Summary

Problems solved by technology

Among them, mechanical screens and centrifugal screening methods cannot separate smaller particles of inorganic impurities; eddy current screening methods are generally only suitable for separating metal-like inorganic substances; the method of screw extrusion has limited extrusion force and cannot fully separate organic and inorganic substances. Separation of organic matter, causing waste of organic matter

Embodiment 1

[0038] Please also see Figure 1 to Figure 6 , as shown in the figure, a food waste pretreatment equipment includes an extrusion cylinder 1, a feed port 11 and a discharge port respectively arranged on the upper side and the lower side of the extrusion cylinder, and the discharge port includes an organic matter discharge port 12 and the inorganic matter discharge port 13, the extrusion cylinder is provided with an extrusion mechanism 2 for extrusion and separation of kitchen waste, two groups of extrusion mechanisms are symmetrically arranged, and the space between the two groups of extrusion mechanisms forms a separation chamber 15 , the device also includes a control mechanism.

[0039] The extruding mechanism includes a main extruding mechanism and an auxiliary extruding mechanism arranged on the left and right, the inorganic matter outlet 13 is arranged on the right side of the organic matter outlet 12, and a screen 16 is arranged on the organic matter outlet. In the init...

Embodiment 2

[0069] The rest is the same as that of Embodiment 1, except that the auxiliary extrusion mechanism can be a baffle, and the baffle is arranged in the extrusion cylinder to separate the organic matter discharge port from the inorganic matter discharge port. In the initial stage of extrusion, the organic matter is separated and broken through the movement of the main extrusion mechanism, and the organic matter is screened out in the first step. The pressure sensor can be set on the baffle. When the set pressure is reached, the main extrusion mechanism will stop moving and maintain the pressure for a period of time to ensure the full discharge of organic matter. In the later stage of extrusion, the baffle is directly pulled out of the extrusion cylinder, and the main extrusion mechanism directly pushes out the separated inorganic matter to the discharge port of the inorganic matter, and then resets.

[0070] The invention discloses a kitchen garbage pretreatment device. By settin...

Abstract

The invention discloses kitchen waste pretreatment equipment. With the adoption of two extrusion mechanisms, organic substances in kitchen waste are extruded and screened out, and then inorganic substances are detruded wholly, so that the organic substances are effectively separated from the inorganic substances; treatment steps are simplified; a separating effect is improved; purification of the kitchen waste is realized; and fermentation for the organic substances of the kitchen waste is prepared. With adoption of a residue discharge opening, when a main extrusion mechanism resets, residues on a screen mesh can be scraped by the bottom of an extrusion piston, and then are moved along with the extrusion piston to the residue discharge opening to be discharged, so that the integration of return stroke and cleaning is realized. Blades are mounted on the extrusion piston, and can be used for smashing the inorganic substances during extrusion separation, so that the integration of extrusion, smashing and discharge is realized.

Description

technical field [0001] The invention belongs to the technical field of garbage sorting equipment, and in particular relates to a kitchen garbage pretreatment equipment. Background technique [0002] Kitchen waste, commonly known as swill, is the domestic waste formed by residents in the process of living consumption. Its components are complex, mainly including oil, water, fruit peels, vegetables, rice noodles, fish, meat, bones, waste tableware, plastics, paper towels, etc. This kind of substance is very perishable, emits foul smell, and spreads bacteria and diseases. The amount of food waste in my country is very large, and it is rising rapidly, posing serious health and safety risks. [0003] For the existing kitchen waste, the treatment methods generally include anaerobic fermentation, aerobic fermentation, oil extraction, composting, etc. No matter what treatment method is used, it is necessary to separate the organic matter from the inorganic matter in the kitchen waste...
