Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of down sorting and processing equipment, specifically a centrifugal sorting and purification device for high-loft down. Background Technology
[0002] Down raw materials are usually collected together with feathers. After entering the processing plant, the raw materials need to undergo pretreatment, initial sorting, washing, fine sorting and post-treatment before they can be used to make down products.
[0003] In pretreatment and initial sorting, air classifiers are generally used. These classifiers utilize the difference in mass between feathers and down, using upward airflow to separate the feathers and down into layers. During sorting, the raw material needs to be continuously agitated and patted using a drainer to separate the feathers and down as much as possible, facilitating sorting. This also removes large particles of impurities such as dust and sand. This process damages the down clusters, leading to a decrease in their loft. Furthermore, during the agitation process, some feathers break into tiny filaments. These impurities have a similar density to down, making complete separation difficult with air classifiers. This necessitates a tall air classifier box and multiple air separation processes, resulting in high energy consumption. Utility Model Content

[0009] The sorting component includes a drive component, which is connected to a transmission shaft. The end of the transmission shaft passes axially downward through the feeding component and is equipped with a centrifugal component. When the drive component is working, it can drive the transmission shaft to drive the centrifugal component to rotate. By utilizing centrifugal force and the difference in density of the components in the material, sorting is achieved.
[0010] Preferably, the separation tank includes a tank body, and a plurality of second discharge ports are provided on the upper side of the tank body.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1:
[0028] Please see Figure 1-4 The present invention will describe the above technical solution in detail through the following embodiments:
[0029] A centrifugal sorting and purification device for high-loft down feathers includes:
[0030] Separation tank 1, with a feeding component 2 in the middle of the top surface of separation tank 1, and a sorting component 3 in the center of the feeding component 2.
[0031] The separator 1 includes a tank body 11, and the upper side of the tank body 11 is provided with several second discharge ports 13.
[0032] There are six second discharge ports 13, which are evenly distributed around the tank body 11. Each second discharge port 13 is fixed to a collection hopper 14 by bolts, and the bottom of the collection hopper 14 is provided with a discharge pipe 15.
[0033] The discharge pipe 15 is used to discharge substances with higher density in the material.
[0034] The tank body 11 has a first discharge port 12 at the center of the bottom.
[0035] The first discharge port 12 is used to discharge the lighter substances in the material.
[0036] The feeding assembly 2 includes a feeding hopper 21, which is located above the top surface of the separation tank 1. The bottom of the feeding hopper 21 is provided with a feeding pipe 23, which extends downward through the top surface of the separation tank 1 and into the separation tank 1. The feeding assembly 2 is used to feed materials into the separation tank 1.
[0037] The bottom of the feed hopper 21 is conical, wider at the top and narrower at the bottom, and the top is cylindrical. It is fixedly installed on the top surface of the separator 1 by welding.
[0038] A feed pipe 22 is horizontally provided on the upper side of the feed hopper 21. The feed pipe 22 is tangent to the side of the feed hopper 21, and the material enters the feed hopper 21 tangentially from the feed pipe 22.
[0039] The material is blown into the feed pipe 22 using a known vacuum feeding device. After entering the feed hopper 21 from the feed pipe 22, it moves in a spiral motion along the inner wall of the feed hopper 21, causing the cohesive material to disperse during transportation. Then it gathers at the feeding pipe 23 and enters the tank 11 from the feeding pipe 23.
[0040] In this example, the vacuum suction equipment can use a well-known vacuum suction tube, which is a commonly used suction equipment in the down processing industry.
[0041] The sorting component 3 includes a drive component, which is connected to a transmission shaft 34. The end of the transmission shaft 34 extends axially downward through the feeding component 2, which is equipped with a centrifugal component. When the drive component is working, it can drive the transmission shaft 34 to drive the centrifugal component to rotate. By utilizing centrifugal force and the different densities of the components in the material, sorting is achieved.
[0042] The drive assembly includes a power source 31, which is an electric motor. The power source 31 is fixedly mounted on the top surface of the tank 11 by bolts. The output shaft of the power source 31 is connected to the top of the transmission shaft 34 through a coupling 32. When the power source 31 is working, it can drive the transmission shaft 34 to rotate through the coupling 32, thereby driving the centrifugal assembly to rotate.
[0043] A rotating element 33 is provided between the top of the drive shaft 34 and the tank body 11. The rotating element 33 may be a tapered roller bearing, which is used to limit the axial and radial movement of the drive shaft 34.
[0044] The bottom of the feeding pipe 23 is higher than the upper edge of the second discharge port 13, and the height of the centrifugal assembly is between the center and the upper edge of the second discharge port 13.
[0045] There is a gap between the bottom of the feeding pipe 23 and the centrifugal assembly. After the material is discharged from the feeding pipe 23, it falls onto the centrifugal assembly. When the centrifugal assembly rotates, it can drive the material to rotate. Under the action of centrifugal force, the material flies out. The denser substances fly farther and will fly into the second discharge port 13. The lighter substances will miss the second discharge port 13 and fall to the bottom of the tank 11.
[0046] The centrifugal assembly includes a centrifugal disc 35, the top surface of which protrudes upward in a frustum shape, and the edge of the centrifugal disc 35 is provided with an upward-curving skirt 37, which is inclined outward at an angle of 45-60°.
[0047] The skirt 37 allows the material to fly diagonally upwards, increasing its flight path and distance, and improving the separation effect. In this embodiment, the inclination angle of the skirt 37 is set to 45°.
[0048] The top surface of the centrifuge disc 35 is uniformly provided with several guide protrusions 36. The guide protrusions 36 are made of flexible material and have an angle between the guide protrusions 36 and the diameter of the centrifuge disc 35, with the angle being 15-30°.
[0049] The guide protrusion 36 is made of rubber or silicone to reduce the impact on the down. When the centrifugal disc 35 rotates, the guide protrusion 36 can guide the airflow and material movement, generate radial airflow, increase the speed at which the material leaves the centrifugal disc 35, and enable the centrifugal disc 35 to complete the material sorting at a lower speed, reducing damage to the down.
[0050] A mounting sleeve 38 is provided in the middle of the drive shaft 34 and inside the feed pipe 23. Four dispersing rollers 39 are radially welded on the outer side of the mounting sleeve 38.
[0051] Mounting sleeve 38 is fixedly connected to drive shaft 34 by screws. When drive shaft 34 rotates, it can drive dispersion roller 39 to rotate through mounting sleeve 38, further dispersing the agglomerated material. By loosening the screws of mounting sleeve 38, the height of mounting sleeve 38 can be adjusted to obtain different dispersion effects.
[0052] Working principle:
[0053] The power source 31 is controlled to work, driving the transmission shaft 34 to rotate, which in turn drives the centrifugal disc 35 and the dispersing roller 39 to rotate.
[0054] The material is sucked into the feed pipe 22 by the vacuum suction pipe. The material enters the feed hopper 21 from the feed pipe 22, moves spirally along the inner wall of the feed hopper 21, and after initial dispersion, falls into the feed pipe 23.
[0055] After the material enters the feeding pipe 23, it is dispersed by the dispersing roller 39 and falls evenly onto the centrifugal disc 35.
[0056] The rotating centrifugal disc 35 can drive the material to rotate, and the material flies out of the centrifugal disc 35 under the action of centrifugal force.
[0057] During this process, the guide protrusion 36 can guide the airflow and material movement, generate radial airflow, increase the speed at which the material leaves the centrifugal disc 35, and the skirt 37 can make the material fly obliquely upward, increasing the flight path and flight distance of the material.
[0058] The denser material will enter the collecting hopper 14 from the second discharge port 13 and then be discharged from the discharge pipe 15. The lighter fluff will miss the second discharge port 13, fall to the bottom of the tank 11, and be discharged from the first discharge port 12.
[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
