Impurity removal and drying device for down feather

Abstract

The invention discloses an impurity removal and drying device for down feather. The impurity removal and drying device comprises a shell, and the shell is arranged at the upper end of a base. A controller is arranged at the lower end of the base, and a feeding port and an exhaust pipe are arranged at the upper end of the shell. A screening plate is arranged in the shell, and a vibration motor is arranged at the lower end of the screening plate. A discharging port is formed in one end of the screening plate, and an impurity collecting box is arranged below the screening plate. A heating layer is arranged on the outer wall of the shell, and a heating block is arranged in the heating layer. The heating layer is connected with an air blower through a ventilating pipe, and the air blower is mounted at the upper end of the base. An air inlet pipe is horizontally arranged in the shell, and each of the two ends of the air inlet pipe communicates with the heating layer. A temperature inductor is arranged on the inner wall of the shell, and a cold air inlet is formed in the upper end of the shell. The cold air inlet is connected with an air cooler through a cold air pipe, and the air cooleris arranged at the upper end of the base. According to the impurity removal and drying device, gravels, metal filling and other impurities in the down feather can be automatically removed, drying temperature can be controlled, the situation that the temperature is too high, and consequently the down feather is damaged is avoided, and the down feather is dried evenly and fast.

Description

technical field [0001] The invention relates to the field of down processing equipment, in particular to a down impurity removal and drying device. Background technique [0002] Down is the fluff that grows on the abdomen of geese and ducks, and is called feathers in flakes. Since down is a kind of animal protein fiber, there are tens of thousands of small triangular pores densely covered on the down ball-shaped fiber, which can shrink and expand with the change of temperature, and has the function of temperature adjustment, which can absorb the flowing hot air from the human body and isolate the invasion of cold air from the outside. . From the analysis of the bulkiness test, down is one level higher than silk, cotton and other thermal insulation materials. For example, the minimum standard of 450 degrees fluffy 90 duck down is also more fluffy than silk and cotton, so down is purely used as a thermal insulation material. The economic value is much higher than other therm...

AI Technical Summary

Problems solved by technology

In the process of processing down, down needs to go through cleaning, impurity removal, drying and other processes. The current drying equipment has a monotonous function, which is separated from the impurity removal function, and the drying temperature is not easy to control. When the temperature is too high, it is easy to damage the down. Reduce the quality of down
