Device and method for extracting sticky down by deeply processing down

Abstract

The invention discloses a device and a method for extracting sticky down by deeply processing down. The device for extracting the sticky down by deeply processing the down comprises a feather yarn separation box (1), a neck feather yarn separation box (2) and a down flying yarn separation sieve (3) which are connected in turn. The method comprises the following steps of: 1) disinfecting, sterilizing and deodorizing feathers by using a high temperature of 120 DEG C generated by water vapor and pressurizing to make the feathers separated to form the down; 2) putting the down into the feather yarn separation box through a feeding hole for processing to separate feather yarns; 3) putting the down in a sieve barrel into the neck feather yarn separation box through a discharging opening for processing to separate neck feather yarns; and 4) putting the down in an inner box body into the down flying yarn separation sieve for processing to separate down flying yarns. By the device and the method, the feather yarns, the neck feather yarns and the down flying yarns can be efficiently separated to extract the sticky down with the down content of 97 percent.

Description

technical field [0001] The invention relates to the processing field of water-washed down, in particular to a device and method for deep-processing down and extracting string down. Background technique [0002] At present, with the improvement of people's living standards, people are pursuing a convenient and comfortable living space, especially in terms of basic necessities of life, food, housing and transportation. The padded jackets, leather jackets, and woolen sweaters that people used to wear are gradually eliminated by the market and replaced by modern fashionable down clothing. The market development prospect is very optimistic. Down industry generally extracts down with a down content of 80% to 90%. The feather resource utilization rate is low, the bulkiness is poor, the loss is large, the added value is small, the economic return is poor, and it contains a small amount of peculiar smell. Down products made of down with 80% to 90% down content as filling materials c...

Problems solved by technology

Down industry generally extracts down with a down content of 80% to 90%. The feather resource utilization rate is low, the bulkiness is poor, the loss is large, the added value is small, the economic return is poor, and it contains a small amount of peculiar smell.

Down products made of down with 80% to 90% down content as filling materials consume a lot of down materials, and the warmth retention is not ideal, and the hand feeling is poor, the appearance is bloated, and it is prone to running down and leakage. Down with a down content of 80% to 90% still contains impurities such as flakes, neck hairs and velvet flying silk.

Because the flakes, neck hairs, and velvets contained in down are difficult to separate, some down product processing enterprises can only manually separate the down and high velvet in order to prevent the down products from running down and leaking. Low Yield

At present, there is no mechanized technology that can separate wool flakes, neck hairs, and velvet flying silk to extract high velvet with more than 95% velvet
