Embodiment 1

[0067] see figure 1 as well as figure 2 , this embodiment provides a three-phase separation method for harmless swill, which can be used by using a three-phase separation device for swill. Wherein, the swill three-phase separation device includes a frame body 1, a sorting system, a crushing system, an extrusion system, an oil-water separation system, and a feeding system. In this embodiment, the three-phase separation method for harmless swill includes the following steps.

[0068] Step 1. Sorting out the hard foreign matter in the kitchen waste, and performing solid-liquid separation on the remaining kitchen swill to obtain solid wet garbage and liquid oil-water mixture. In this embodiment, a sorting system is used for sorting. Among them, the sorting system is used to sort and separate food waste to remove hard foreign matter, and obtain solid wet waste and liquid oil-water mixture. Wherein, the sorting system includes a sorting platform 2 and a net plate 3 . The sorti...

Embodiment 2

[0105] This embodiment provides a three-phase separation method for harmless swill, which adds the step of scraping out scum on the basis of embodiment 1. Wherein, the method for scraping out oil scum comprises the following steps:

[0106] (I) Detect the liquid level of the liquid in the oil scraping mechanism;

[0107] (II) judging whether the liquid level height is greater than a preset height one;

[0108] (Ⅲ) When the height of the liquid level is greater than the preset height 1, the oil scraping mechanism is driven to scrape the liquid;

[0109] (Ⅳ) judging whether the liquid level height is greater than a preset height two;

[0110] (Ⅴ) When the liquid level is higher than the liquid level two, stop conveying the oil-water mixture to the receiving space;

[0111] (Ⅵ) Calculate the height change value of the liquid level within a preset time;

[0112] (VII) According to the change value of the liquid level, adjust the power of the oil scraping mechanism according to...

Embodiment 3

[0114] This embodiment provides a three-phase separation device for harmless swill, which applies the three-phase separation method for harmless swill in embodiment 1 or embodiment 2, and includes a feeding module, a sorting module, a crushing module, Extrusion module and oil-water separation module. The feeding module is used to lift and feed the food waste to be separated into three phases in the garbage bin 5 through the hoist 4 . The sorting module is used to receive the food waste in the garbage bin 5, sort out the hard foreign matter in the food waste, and perform solid-liquid separation on the remaining food swill to obtain solid wet waste and liquid waste. Oil-water mixture. The crushing module is used to convey the wet waste to a crushing system for crushing to obtain crushed products. The extrusion module is used to make the crushed product move directionally in the screen tube 70 through the screw rod 54, so as to extrude and dehydrate the crushed product, and adj...

Abstract

The invention discloses a harmless three-phase separation method and device for swill. The harmless three-phase separation method for the swill comprises the following steps that hard foreign matter in kitchen waste is sorted out, and solid-liquid separation is conducted on the remaining kitchen swill to obtain wet waste and an oil-water mixture; the wet waste is crushed to obtain a crushed product; the crushed product is made to move in a screen pipe in an oriented mode so that the crushed product can be extruded and dehydrated; and the oil-water mixture and a liquid product extruded by the screen pipe are mixed to form an oil-water mixed solution, then the oil-water mixed solution is layered in an oil separation box, and finally floating oil residues in an oil layer are scraped out to separate out waste water and grease. According to the harmless three-phase separation method and device for the swill, the discharging amount of extruded materials can be controlled, then the water content of the discharged materials is adjusted, the discharging amount can be increased when discharging needs to be accelerated, and therefore control over the water content is achieved, and the extruded materials can reach the required standard.

Description

technical field [0001] The invention relates to a separation method in the technical field of kitchen waste treatment, in particular to a three-phase separation method for harmless swill, and a three-phase separation device for harmless swill. Background technique [0002] Swill is a kind of domestic waste formed by residents in the process of daily consumption. The various organic substances contained in it are very easy to corrode in summer; the leftover soup and rancid water contain a lot of it, which is easy to cause waste in the process of garbage collection and transportation. Pollution; at the same time, kitchen swill is the main source of leachate in landfills, and it is also an important cause of air pollution and fly breeding; the swill pigs fed by swill and the swill oil extracted to the market seriously endanger human health. A large amount of kitchen swill has become the main source of urban pollution and harm to human health. [0003] At present, there are gen...
