Description

Technical Field

[0001] This utility model relates to the technical field of down processing equipment, specifically a down-proof processing device. Background Technology

[0002] Down products are widely used in clothing and bedding due to their lightweight and warmth, but the "down leakage" problem during processing has long plagued the industry. Traditional processing equipment mainly separates the feather roots from the down clusters through physical beating and airflow separation.

[0003] However, simple air separation is not effective at separating tiny down feathers, and residual feathers increase the risk of the finished product puncturing the fabric. Electrostatic separation is also used to separate down feathers, but it is sensitive to material and ambient humidity. If the ambient humidity is too high, the down will absorb water molecules, increasing its own moisture content and causing electrostatic shielding. Conversely, when the material is relatively dry, during air separation, mechanical agitation and beating can generate static electricity through friction, causing down clusters and tiny feathers to adhere together, affecting subsequent electrostatic separation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a processing device for preventing down from penetrating.

[0005] The technical solution of this utility model is:

[0006] A down-proof processing apparatus, comprising:

[0007] The primary sorting component includes an air separator for air-based screening of down feathers. A fine material outlet is located on one side of the top of the air separator, connected to a feeding component. The feeding component includes a drying component and a feeding component. A secondary sorting component is located at the end of the feeding component. The drying component dries the material after primary screening, and the feeding component feeds the dried material into the secondary sorting component. The secondary sorting component uses electrostatic discharge to perform secondary sorting of the material.

[0008] Preferably, the drying component includes a discharge pipe, which is vertically arranged. The upper end of the discharge pipe is connected to a fine material outlet, and the lower end of the discharge pipe is connected to a discharge hopper. The feeding component is located below the discharge hopper.

[0009] Preferably, a plurality of drying devices are provided in the middle of the side of the discharge pipe, and the drying devices are used to heat the material in the discharge pipe to achieve drying.

[0010] Preferably, the feeding assembly includes a feeding conveyor belt, one end of the top surface of the feeding conveyor belt abutting the bottom surface of the discharge hopper, and the other end of the feeding conveyor belt being connected to the secondary sorting assembly.

[0011] Preferably, the hopper is provided with a discharge baffle on the side near the secondary sorting component, the discharge baffle is parallel to the top surface of the feeding conveyor belt and there is a gap between the discharge baffle and the top surface of the feeding conveyor belt.

[0012] Preferably, a closed chamber is provided on the outside of the discharge baffle and above the feeding conveyor belt. The upper half of the closed chamber near the discharge baffle is connected to a dehumidification duct, which is used to connect to a negative pressure device to discharge air outward.

[0013] Preferably, a humidity sensor is provided on the top surface inside the enclosed chamber, and the humidity sensor is used to monitor the humidity of the environment inside the enclosed chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention dries materials by installing a drying component at the fine material outlet, maintaining appropriate humidity for materials entering the secondary sorting component. This allows for a slight increase in humidity of materials entering the air classifier, reducing static electricity during air classification and facilitating subsequent secondary sorting. The combination of air classification and electrostatic separation improves the separation effect of down and feathers. The dried materials are transported by a feeding conveyor belt, and a closed chamber prevents material scattering. A dehumidification duct exhausts humid air, ensuring suitable environmental humidity. Attached Figure Description

[0024] 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.

[0025] Example 1:

[0026] Please see Figure 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A down-proof processing apparatus, comprising:

[0028] Primary sorting component 1 includes an air separator 11, which is used to screen down by air. The air separator 11 has a fine material outlet 13 on one side of its top. The fine material outlet 13 is connected to a feeding component 2, which includes a drying component and a feeding component. A secondary sorting component 3 is provided at the end of the feeding component. The drying component is used to dry the material after primary screening, and the feeding component is used to feed the dried material into the secondary sorting component 3. The secondary sorting component 3 uses electrostatics to perform secondary sorting of the material.

[0029] The air separator 11 uses a well-known down air separator.

[0030] The bottom left side of the air classifier 11 is provided with a feed pipe 12 for feeding raw materials. The bottom rear side of the air classifier 11 is provided with a coarse material outlet 14 for discharging materials such as feathers, stones, and dust.

[0031] The drying assembly includes a discharge pipe 21, which is vertically arranged. The upper end of the discharge pipe 21 is fixedly connected to the fine material outlet 13 by bolts, and the lower end of the discharge pipe 21 is fixedly installed with a discharge hopper 23 by bolts. The feeding assembly is located below the discharge hopper 23.

[0032] After the initial selection, the material enters the discharge pipe 21 and slowly floats down along the discharge pipe 21 before falling into the discharge hopper 23.

[0033] Two sets of drying equipment 22 are fixedly installed on the middle side of the discharge pipe 21 by bolts. The drying equipment 22 is used to heat the material in the discharge pipe 21 to achieve drying.

[0034] The drying equipment 22 can be a microwave heating device, which uses microwaves to heat the material from the inside and evaporate excess moisture.

[0035] The feed pipe 21 can be divided into two channels, with each set of drying equipment 22 adapted to one channel, improving the drying effect while avoiding over-drying of the material.

[0036] The feeding assembly includes a feeding conveyor belt 24, one end of the top surface of the feeding conveyor belt 24 abuts against the bottom surface of the discharge hopper 23, and the other end of the feeding conveyor belt 24 is connected to the secondary sorting assembly 3.

[0037] The bottom of the discharge hopper 23 is hollow. After the material enters the discharge hopper 23, it falls directly onto the feeding conveyor belt 24. When the feeding conveyor belt 24 is working, it can move the material together and finally enter the secondary sorting component 3. As the material moves with the feeding conveyor belt 24, the temperature will gradually decrease.

[0038] A discharge baffle 25 is welded to the side of the hopper 23 near the secondary sorting component 3. The discharge baffle 25 is parallel to the top surface of the feeding conveyor belt 24 and there is a gap between the discharge baffle 25 and the top surface of the feeding conveyor belt 24.

[0039] The discharge baffle 25 is used to limit the height of the material and ensure that the thickness of the material moving with the feeding conveyor belt 24 is uniform, thereby improving heat dissipation efficiency.

[0040] A closed chamber 26 is provided on the outside of the discharge baffle 25 and above the feeding conveyor belt 24. The upper half of the closed chamber 26 near the discharge baffle 25 is connected to a dehumidification duct 29, which is used to connect to a negative pressure device to discharge air outward.

[0041] The head of the enclosed chamber 26 is fixedly connected to the discharge baffle 25 by bolts.

[0042] The enclosed chamber 26 can prevent the material on the feeding conveyor belt 24 from being scattered by airflow during the movement.

[0043] Negative pressure equipment is a well-known technology, so it is not shown in the figure.

[0044] The negative pressure device can extract the air from the enclosed chamber 26 through the exhaust duct 29.

[0045] A baffle net 28 is attached to the end of the exhaust duct 29 and above the discharge baffle 25. The baffle net 28 is used to prevent material from flying out of the exhaust duct 29.

[0046] A humidity sensor 27 is installed on the top surface inside the sealed chamber 26. The humidity sensor 27 is used to monitor the humidity of the environment inside the sealed chamber 26.

[0047] The exhaust air volume of the dehumidification duct 29 is adjusted according to the monitoring data of the humidity sensor 27, and the air volume is proportional to the humidity.

[0048] The secondary sorting assembly 3 includes a sorting box 31. A feeding conveyor belt 24 is inserted into the sorting box 31 from the left side. The end opening of the sorting box 31 is fixedly connected to the end of the closed chamber 26 by bolts.

[0049] An electrostatic plate 32 is provided on the upper right side of the inside of the sorting box 31. When the electrostatic plate 32 is powered on, it can generate static electricity. The static electricity has different adsorption effects on down clusters and tiny feather roots.

[0050] The bottom of the sorting box 31 is fixed with several discharge hoppers 33 by bolts. A partition 34 is welded between the top of two adjacent discharge hoppers 33. The partition 34 is used to prevent feather roots and down from mixing together again due to air resistance when they fall.

[0051] The leftmost discharge hopper 33 has a scraper 35 fixed to its top left side by bolts. The top surface of the scraper 35 abuts against the bottom surface of the feeding conveyor belt 24 and is used to scrape off the material adhering to the surface of the feeding conveyor belt 24.

[0052] Working principle:

[0053] The initial material is fed into the air separator 11 through the feed pipe 12. Inside the air separator 11, the material is separated by air. Lighter down and tiny feathers are discharged from the fine material outlet 13, while heavier feathers and impurities such as stones are discharged from the coarse material outlet 14.

[0054] It is important to note that the initial material needs to have a certain level of moisture to reduce static electricity during the air separation process.

[0055] After the initial selection, the material enters the discharge pipe 21 and slowly falls down along the discharge pipe 21. During the falling process, the drying equipment 22 heats the material to dry it.

[0056] The dried hot material falls into the hopper 23 and onto the feeding conveyor belt 24.

[0057] When the feeding conveyor belt 24 is working, it will drive the material to move to the right. When the material encounters the discharge baffle 25, the discharge baffle 25 can flatten the material, so that the material thickness is consistent and facilitates heat dissipation.

[0058] As the material enters the enclosed chamber 26, the temperature gradually decreases, while the residual moisture on the surface of the material continues to evaporate.

[0059] Humidity sensor 27 detects an increase in humidity inside the sealed chamber 26 and uses a negative pressure device to extract air from the sealed chamber 26 through the exhaust duct 29.

[0060] The dried and cooled material enters the sorting box 31, at which point the electrostatic plate 32 activates, generating static electricity.

[0061] When the material falls from the end of the feeding conveyor belt 24, the fluff and tiny feathers are attracted by electrostatic forces at different distances, resulting in different falling points and thus falling into different discharge hoppers 33.

[0062] The material attached to the surface of the feeding conveyor belt 24 moves with the feeding conveyor belt 24 and is finally scraped off by the scraper 35 and falls into the leftmost discharge hopper 33.

[0063] 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.
