A kind of down dust separation method

Abstract

The invention discloses a down feather dust separating method.The method includes the steps that firstly, a separating device is made to idle, and a numerical value X monitored by a pipeline dust detector is recorded; a down feather raw material is put into a down feather raw material storage chamber of the separating device, an air blower and a dust collector are started, down feathers and small-particle dust in the down feather raw material storage chamber penetrate through a first filter screen along with airflow and then enter a down feather dust separating chamber, and large-particle impurities are separated out; then, the down feather raw material continues to float along with airflow, and small-particle dust enters a dust monitoring chamber through a second filter screen and is sucked out of the dust monitoring chamber by the dust collector to be recycled; when a numerical value monitored by the pipeline dust detector is smaller than or equal to the original recorded numerical value X, it is judged that separation is completed, and down feathers in the down feather dust separating chamber are qualified.According to the method, impurities and dust in down feathers are constantly separated out and recycled by using the air blower to provide power and utilizing the mobility of air in cooperation with the first filter screen and the second filter screen, and the procedure is simple; besides, the concentration of dust can be monitored, and separation quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of down product production, in particular to a method for separating down dust. Background technique [0002] At present, with the improvement of people's living standards, the demand for down is also increasing, and the quality requirements for down are also getting higher and higher. The dust problem of down is a key factor affecting the quality of down. In the process of producing down, the dust content is often relatively high, which directly affects the quality of down products. During the production or use of down products, due to the high dust content, if the dust is inhaled by production workers or users, it will affect the human respiratory system and pose a hazard to human health. [0003] In the traditional down separation process, it is easy to damage and lose part of the down during the separation process, and the production efficiency of the separation equipment is low and the energy consumpti...

Problems solved by technology

During the production or use of down products, due to the high dust content, if the dust is inhaled by production workers or users, it will affect the human respiratory system and pose a hazard to human health.

[0003] The traditional down and down separation process is easy to damage and lose part of the down during the separation process, and the production efficiency of the separation equipment is low and the energy consumption is large
