Down cluster selection system

Abstract

The invention belongs to the field of down deep processing equipment and particularly relates to a down cluster selection system. The down cluster selection system comprises a down tank and a cylindrical screen portion, an inner cavity of the cylindrical screen portion is communicated with a feeding port to form a feeding cavity which is communicated with an external large down cluster collection component, a small down cluster cavity is formed in an area between the outer wall of the cylindrical screen portion and the inner wall of the down tank and communicated with an external small down cluster collection component, each of a feeding pipeline and a delivery pipeline is provided with an inner negative-pressure environment, and the small down cluster cavity and the feeding cavity are communicated through screen meshes. The feeding cavity is internally provided with a stirring portion; two ends of the cylindrical screen portion are fixedly connected to two opposite side walls of the down tank respectively. The down cluster selection system further comprises a collection trough; the small down cluster collection component comprises a first cavity and a second cavity; stirring teeth are arranged in the first cavity which is communicated with a dust box, and the second cavity is communicated with a small down cluster collection tank. The down cluster selection system has the advantages that high selection quality of large down clusters and small down clusters is realized, and accordingly processing burden of the subsequent procedures can be effectively relieved, and the down cluster selection system is pretty reliable and stable in operation.

Description

technical field [0001] The invention belongs to the field of down processing equipment, and in particular relates to a system for selecting down and down flowers. Background technique [0002] The raw materials for down processing mainly come from the feathers and down of ducks and geese; because of its excellent properties such as softness and warmth, breathability and cold protection, and heat absorption and divergence, it is the best filling for making cold products. Most of the down products currently on the market have a down content of 70% to 90%, and were originally manufactured mainly through the process of washing down. As described in the Chinese patent application with the publication number CN101670340 titled "Sorting Process of Goose Feather and Down", that is, the purpose of selecting the down is achieved by washing, drying and sieving, so as to obtain a relatively high-quality designation. Due to the limitations of traditional water washing and selection, it ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned method still has the following defects: firstly, as the raw material of thick down, due to the differences in the slaughtering environment and even the transportation environment of ducks and geese, there are not only the above-mentioned neck hair pieces, wool pieces, fluff silk, and immature small velvet flowers in it. At the same time, there are often fine debris such as sand particles and even rubble; in the current selection operation process, it is still difficult to have an effective fine-grained treatment method for the above-mentioned debris; often due to small particles of sand, etc. Impurities directly fall into the small velvet collection tank along the sieve holes, which brings difficulties to the subsequent small velvet treatment process; or the impurities directly enter the large velvet collection cabinet, which affects the post-processing of large velvet

Secondly, the current above-mentioned selected equipment often needs to use multiple fans to cooperate with each other according to the volume of the equipment, so as to achieve the effect of its negative pressure to absorb the velvet. Greatly affected the actual production efficiency of the manufacturer

Thirdly, the integral design structure of the traditional trommel screen is not easy to carry, maintain and replace. As a moving part, the huge trommel screen is often damaged due to its own weight and other factors, and because it is an integral part, the damage of part of the structure is often With the update of the overall components, the maintenance cost is large and the cycle is long

Finally, in the current eider down selection equipment as mentioned above, after the small velvet is collected, due to the presence of trivial woven fabrics, sand and gravel, etc. or light or heavy dirt impurities in it, the small velvet is in the After collection, there is still no effective follow-up processing method. It is a pity to discard it and the processing cost is high, which brings a large production loss to the manufacturer.
