AI Technical Summary
Existing drying equipment is prone to breaking down feathers when dealing with clumps of cleaned down feathers due to the impact of the stirring rod, and the drying efficiency is low.
The drying box is equipped with a wire basket, combined with a bladeless fan and a vibration device. The bladeless fan blows hot air upwards and the vibration device loosens the clumps of down. The drying and undried areas are separated by hanging ropes and isolation cloths. An eccentric motor or pneumatic vibrator provides vibration, and heating rods accelerate the drying process.
It effectively prevents the fluff from breaking, improves drying efficiency, reduces drying time, and ensures the fluff remains fluffy, achieving a fast and efficient drying effect.

Abstract
Description
Technical Field
[0001] This utility model relates to down processing equipment, specifically to a rapid drying device that prevents down from clumping and vibrating. Background Technology
[0002] Down jackets are outer garments filled with down feathers. They are large and rounded in shape. Down jackets are generally filled with duck down or goose down. The duck down or goose down is cleaned, sterilized at high temperatures, and then used to fill the garment. Down jackets are an important category of winter clothing, known for their lightweight and warmth. After washing, duck down or goose down inevitably clumps together. To prevent this during subsequent use and to ensure the down is fluffy, it needs to be loosened and dried. Furthermore, to maintain the quality of the down, care must be taken not to break the clumps while loosening the down.
[0003] Chinese Patent Publication No. CN 210711842 U, entitled "Device for Dispersing Clumped Down Feathers," includes a cylinder with a rotating shaft hinged inside. A stirring rod is fixed to the rotating shaft inside the cylinder, and multiple antistatic rods are fixed to each stirring rod. A motor is fixed to the right end of the cylinder, and the motor's output shaft is fixedly connected to the rotating shaft. Multiple fan blades are evenly distributed around the right circumference of the rotating shaft inside the cylinder. A dispersing feed device is located on the upper right side of the cylinder, and a discharge port is located on the lower left side of the cylinder. An antistatic device is located on the right side wall of the cylinder. This invention utilizes horizontal and vertical rods to pre-disperse the down feathers before they enter the cylinder. The down feathers entering the cylinder are dispersed by the antistatic rods on the stirring rods. Simultaneously, the rotating shaft's rotation and the fan blades generate an airflow carrying positive and negative ions within the cylinder, removing static electricity from the down feathers.
[0004] This invention has the problem that using a stirring rod to tap the clumps can easily break up the fluff. Summary of the Invention
[0005] This invention addresses the problem that existing drying devices often use simple stirring rods to break up clumps of down after washing, which can easily cause the down to scatter. Therefore, a vibration-assisted rapid drying device is designed to prevent down from clumping.
[0006] This utility model provides a rapid drying device with vibration to prevent down from clumping, comprising: a drying chamber; a cover with a return air duct on the top of the drying chamber; a wire basket inside the drying chamber; a bladeless fan below the wire basket; a second grid drawer below the bladeless fan; and a discharge hopper at the bottom of the drying chamber; a connecting pipe between the cover and the drying chamber, with one end connected to the top of the cover and the other end connected to the side wall of the drying chamber, positioned at a height between the wire basket and the second grid drawer; a hanging rope and a separating cloth between the wire basket and the drying chamber; a drawer opening on the side wall of the drying chamber for housing the second grid drawer; several heating rods on the inner wall of the drying chamber; and at least one vibration device on the outer wall of the wire basket.
[0007] When using the rapid drying device provided by this utility model, first open the lid of the drying chamber and place the washed, drained, and preliminarily dried down feathers inside. Draining reduces the drying time required for the down feathers in the drying chamber and also reduces the overall humidity inside the drying chamber. When the feathers are placed in the net basket, due to the placement height, there may be a problem of feathers falling directly from the gap between the net basket and the inner wall of the drying chamber. In this case, the isolation cloth separates the area above and below the net basket.
[0008] An eccentric motor or pneumatic vibrator vibrates the wire basket, loosening the clumps of down. Simultaneously, a bladeless fan blows hot air upwards, expelling the dried down through a connecting pipe at the top, which then transports it to the second mesh drawer. Since both the wire basket and the second mesh drawer have mesh bottoms, down feathers smaller than or equal to the mesh size will automatically fall. If down hasn't fallen from the second mesh drawer by the set drying time, the drawer can be pulled out of the drying chamber to remove all the down inside at once.
[0009] Preferably, there are two vibration devices, which are mirrored about the midpoint of the basket. The basket is rectangular, with an opening on the top and a mesh on the bottom.
[0010] An eccentric motor was selected for the vibration device.
[0011] Preferably, there are two vibration devices, which are mirrored about the midpoint of the basket. The basket is disc-shaped with an opening on the top and a mesh on the bottom.
[0012] A pneumatic vibrator was selected as the vibration device.
[0013] The shape of the basket can be a cuboid corresponding to the drying box, or it can be a disc shape; the vibrator can be an eccentric motor or a pneumatic vibrator, and four combinations can be formed by combining two of them.
[0014] Preferably, a positioning rod is provided on the inner wall of the drying oven at the same height as the wire mesh basket, and a limiting spring is fitted on the positioning rod. One end of the limiting spring abuts against the inner wall of the drying oven, and the other end is fixed to the outer wall of the wire mesh basket.
[0015] Limiting springs can reduce the impact on the suspension rope, thereby increasing the service life of the suspension rope.
[0016] Preferably, the bottom surface of the basket is provided with several vertically arranged cylinders, arranged in an array, with the spacing between them being larger than the mesh gap on the bottom surface of the basket, and the top surface of the cylinders being a hemisphere.
[0017] The cylinder can enhance the breaking up of clumps of down when they impact the bottom of the basket.
[0018] Preferably, the bladeless fan's air duct axis is a vertical line that passes through the midpoint of the basket when it is stationary.
[0019] The bladeless fan directs airflow vertically upwards, and the base is located outside the drying chamber. The connecting pipe between the fan duct and the base passes through the side wall of the drying chamber.
[0020] Preferably, the distance between the air outlet plane of the bladeless fan and the bottom surface of the basket is equal to 1 / 2 of the length of the long side of the bottom surface of the basket or the radius of the bottom surface of the basket.
[0021] The distance between the air inlet plane of the bladeless fan and the bottom surface of the second grid drawer is equal to the distance between the air outlet plane of the bladeless fan and the bottom surface of the basket.
[0022] As a preferred option, the suspension rope is made of steel wire rope and the suspension point is rotationally symmetrical about the midpoint of the basket.
[0023] The isolation cloth is made of gauze; the length of the gauze is greater than the straight-line distance between the side wall of the mesh basket and the top corner of the drying oven.
[0024] The isolation cloth is detachably connected to the side wall of the basket, and the inner wall of the isolation cloth drying box is detachably connected.
[0025] The beneficial effects of this utility model are as follows: the clumps of down to be dried are collected by the mesh basket, and the already dried down is sifted out by the bladeless fan while being dried upwards, and the already dried down is carried away by the internal hot air flow.
