Spiral material conveying and sorting machine for kitchen waste pretreatment system

Abstract

The invention discloses a spiral material conveying and sorting machine for a kitchen waste pretreatment system, comprising: a sorting box, the top end of which is open and is covered with a box cover, and one side of the top end of the box cover is provided with a waste throwing port; the screen partition plate is fixed to the open end of the sorting box and divides the internal space of the sorting box into an upper slag chamber and a lower slurry chamber, a slag outlet is formed in one side of the bottom end of the upper slag chamber, a plurality of draining holes are formed in part of the bottom wall of the lower slurry chamber, and outer draining sleeves are fixed to the positions, located at the draining holes, of the lower slurry chamber; a slurry outlet is formed in one side of the bottom end of the outer draining sleeve, and a slurry outlet is formed in the other side, away from the outer draining sleeve, of the bottom wall of the lower slurry chamber; the two first shaftless spiral conveying mechanisms are arranged side by side and are both arranged in the upper slag material chamber; and the second shaftless spiral conveying mechanism is arranged in the lower slurry chamber. Compared with a traditional drum screen or a vibrating screen, the spiral material sorting machine is stable in equipment operation, balanced in material processing speed and low in equipment failure rate.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment devices, and more specifically relates to a spiral material conveying and sorting machine used in a kitchen waste pretreatment system. Background technique [0002] my country has a well-developed catering industry and is a world-renowned food powerhouse. Moreover, with economic growth, people's living standards improve, and consumption in catering is increasing day by day, followed by food waste. If food waste is not disposed of in time, it will cause great pressure on the environment and will Let harmful substances flow into the ecosystem. [0003] Due to the diversity and complexity of food waste components, in the pretreatment process, the food waste after measurement and weighing must be sorted before entering the subsequent pulping process to ensure the normal operation of the pulping machine and production Produce qualified slurry. At present, drum screens or vibrating sc...

AI Technical Summary

Problems solved by technology

The drum sieve commonly used in the food waste sorting process, in the process of use, the hard materials in the food waste, such as bones, plastic bags, bottles and cans, etc. block the screen holes, due to the diversity of materials, the density is different , the discharge speed is also different, so it is difficult to determine the processing capacity of the machine; when the vibrating screen is processing food waste, due to the heavy screen body and high vibration frequency, there are often mechanical failures of linkage parts damage, and the equipment operating rate Low; and manual sorting, its work efficiency is low, and the operating environment is poor, which does not meet environmental protection requirements
