Abstract
Description
Technical Field
[0001] This invention belongs to the field of down product processing technology, specifically, it relates to a down antibacterial treatment device and method based on high-temperature steam. Background Technology
[0002] Down, as a high-quality insulating material, is widely used in clothing, bedding, and other fields. However, down is prone to the growth of bacteria, mold, and other microorganisms during processing. If it is not effectively treated with antibacterial agents, it may cause unpleasant odors, trigger allergic reactions, or even harm health. Therefore, antibacterial treatment of down is a crucial step in down processing.
[0003] Currently, commonly used antibacterial treatment methods for down mainly include chemical soaking, ultraviolet irradiation, and ordinary steam heating. Chemical soaking requires antibacterial agents, which not only increases production costs but may also lead to chemical residues, posing potential hazards to the environment and users. Ultraviolet irradiation only has a certain bactericidal effect on the surface of the down, and its bactericidal effect on down accumulated inside is poor. Furthermore, the limited penetration of ultraviolet light makes it difficult to achieve uniform treatment. While ordinary steam heating can kill microorganisms to some extent using high temperatures, it has the following drawbacks:
[0004] Uneven sterilization: In traditional steam treatment equipment, steam is usually injected from a fixed position, and the down accumulates in the container. It is difficult for the steam to mix fully with the down, which can easily lead to local overheating or incomplete sterilization, affecting the consistency of the treatment effect.
[0005] High energy consumption: After steam comes into contact with down, some of the residual heat is directly emitted with the exhaust gas without being recovered and utilized, resulting in energy waste. At the same time, when cold down comes into direct contact with high-temperature steam, the steam is prone to rapid condensation, increasing the humidity of the down. Subsequent additional drying processes are required, further increasing energy consumption.
[0006] Steam leakage and temperature runaway: During the feeding process, high-temperature steam inside the equipment can easily leak out from the feeding port, resulting in not only heat loss but also potential burns to operators. Furthermore, different types and qualities of down have varying tolerances to high temperatures; excessively high steam temperatures can damage softer down, affecting its loft and warmth retention. Most existing equipment lacks the ability to flexibly adjust the inlet air temperature. To address the aforementioned issues, this application proposes a device and method for antibacterial treatment of down based on high-temperature steam. Summary of the Invention
[0007] In view of the problems in the related technologies, the present invention proposes a down antibacterial treatment device and method based on high-temperature steam to overcome the above-mentioned technical problems existing in the existing related technologies.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: A down antibacterial treatment device based on high-temperature steam includes a fixed cylinder, a feeding cylinder fixedly installed on the top of the fixed cylinder, the feeding cylinder and the fixed cylinder being interconnected, a feeding hopper installed on the top of the feeding cylinder, a collection box installed on the bottom of the fixed cylinder, two conical hoppers installed on the fixed cylinder, an exhaust ring installed on the top of the upper conical hopper, and an air inlet pipe installed on one side of the fixed cylinder. An adaptive antibacterial mixing mechanism includes an active tube, which is rotatably installed inside a fixed cylinder. A positioning box is fixedly installed at one end of an air inlet pipe. The positioning box is rotatably connected to the active tube, and the active tube and the positioning box are in communication with each other. The feeding mechanism includes two partition plates and two adjusting plates. The two partition plates are fixedly installed on the inner wall of the feeding cylinder, and the two adjusting plates are rotatably installed at the bottom of the partition plates. The waste heat drying mechanism includes a heat exchange box, which is fixedly installed on one side of the feeding cylinder, and a connecting pipe is installed at the bottom of the heat exchange box, which is connected to the exhaust ring. The temperature control mechanism includes a temperature control cylinder, which is fixedly installed on the outside of the air inlet pipe, and a drain pipe is installed on the outside of the temperature control cylinder.
[0009] Preferably, the adaptive antibacterial mixing mechanism further includes two agitator nozzles, which are fixedly installed at the bottom of the active tube and communicate with each other. The air outlet of the agitator nozzles is offset upward at a 30-degree angle in the vertical direction of the active tube. Three fixing rods are fixedly installed on the inner wall of the fixing cylinder and are fixedly connected to the positioning box.
[0010] High-temperature steam inside the active tube is ejected through a pulsating nozzle. The nozzle outlet is offset by 30 degrees vertically from the active tube, causing the steam to blow away the down feathers above, reducing their falling speed and effectively sterilizing them at high temperature. The fixing rod also helps to limit the positioning box and the active tube.
[0011] Preferably, the active tube is equipped with two sets of drive nozzles, each set of drive nozzles has two nozzles, and both sets of drive nozzles are located inside the conical hopper. The air outlet of the drive nozzle is set at a 30-degree angle to the tangent of the active tube, and two stirring rods are fixedly installed on the active tube, and the stirring rods cooperate with the feeding cylinder.
[0012] By setting the air outlet of the drive nozzle at a 30-degree angle to the tangent of the active tube, the drive nozzle, when spraying air, uses the reverse force of the steam to drive the active tube to rotate, thereby causing the drive nozzle to blow the down laterally and perform a lateral sterilization operation. At the same time, the drive nozzle is located inside the conical hopper, which allows the steam sprayed by the drive nozzle to be fully mixed with the down in the conical hopper, increasing the sterilization effect.
[0013] Preferably, the feeding mechanism further includes two through holes, which are respectively provided on two isolation plates, and the adjusting plate is provided with a connecting hole. The connecting hole and the corresponding through hole cooperate with each other. Both adjusting plates are fixedly connected to the active tube, and the active tube is rotatably connected to the two isolation plates.
[0014] The down feathers are fed from above by the interconnection between the through holes on the isolation plate and the through holes on the adjustment plate. At the same time, the connecting holes on the two adjustment plates are staggered, so that when the two adjustment plates rotate synchronously, they can intermittently seal the down feathers on the hopper to prevent the leakage of residual heat steam.
[0015] Preferably, the waste heat drying mechanism further includes two corrugated heat exchange tubes, which are connected to the feeding cylinder and located between two isolation plates. A blower is installed on one side of the heat exchange box, and the blower is connected to the two corrugated heat exchange tubes.
[0016] By setting up two corrugated heat exchange tubes, heat can be exchanged with the discharged steam, which heats the dry gas inside the corrugated heat exchange tubes and preheats the down in the feed cylinder, reducing the condensation rate of the steam when the down comes into contact with the steam, thereby reducing the humidity when the steam comes into contact with the down.
[0017] Preferably, the temperature control mechanism further includes a spiral condenser tube, which is fixedly sleeved on the outside of the fixed cylinder, and the top end of the spiral condenser tube is connected to the bottom of the heat exchange box.
[0018] By using spiral condenser tubes, the steam discharged from the heat exchange box can be further cooled and the liquid can be injected into the temperature control cylinder.
[0019] Preferably, the temperature control mechanism further includes a piston plate, which is slidably mounted on the inner wall of the temperature control cylinder, and the bottom end of the spiral condenser tube and the drain pipe are located on the same side of the piston plate, and the piston plate is slidably connected to the air inlet pipe.
[0020] The piston plate allows for adjustment of the liquid length within the temperature control cylinder, which in turn adjusts the contact time between the air intake pipe and the cooling liquid in the cylinder. This, in turn, regulates the air intake temperature, preventing excessively high temperatures that could damage softer down feathers.
[0021] Preferably, a rotating ring is rotatably connected to the outer side of the temperature regulating cylinder, and two push rods are fixedly installed on one side of the piston plate, with the rotating ring and the two push rods being connected in a transmission manner.
[0022] Preferably, two positioning gears are rotatably connected to one side of the temperature regulating cylinder. The positioning gears are threadedly connected to the corresponding push rods, and an internal gear ring is fixedly installed on the inner side of the rotating ring. The internal gear ring is threadedly connected to the two positioning gears.
[0023] By rotating the rotating ring, the rotating ring drives the internal gear ring to rotate. The internal gear ring meshes with the two positioning gears, thereby driving the two positioning gears to rotate. The positioning gears are connected to the push rod by threads, thereby driving the piston plate to move in position, which in turn can adjust the temperature regulation effect on the intake manifold.
[0024] In summary, the technical effects and advantages of this invention are as follows: 1. Highly effective and uniform antibacterial and bactericidal effects: By spraying steam upwards at a 30-degree angle from the nozzle, the down feathers above can be agitated, slowing their descent and increasing the contact time between the steam and the down feathers, thus achieving thorough high-temperature sterilization. By driving the nozzle to spray steam at a 30-degree angle tangentially, the steam reaction force automatically drives the active tube to rotate, causing the nozzle to blow the down feathers laterally, so that the steam and down feathers are mixed in all directions within the conical hopper, significantly improving the uniformity and effectiveness of sterilization.
[0025] 2. Adaptive Hybrid and Energy-Saving Drive: The tangential jet design of the drive nozzle can drive the active tube to rotate without additional power, simultaneously completing stirring and jet sterilization, reducing equipment energy consumption. The stirring rod rotates with the active tube, further agitating the down in the feeding cylinder, preventing accumulation, and promoting dynamic mixing of steam and down.
[0026] 3. Intermittent sealed feeding to prevent steam leakage: The connecting holes on the two regulating plates are staggered, and as the main tube rotates, they alternately connect with the through holes on the isolation plate to achieve intermittent material discharge. This not only controls the feed rate but also effectively prevents high-temperature waste heat steam in the fixed cylinder from leaking out of the feeding hopper, reducing heat loss and steam pollution in the operating environment.
[0027] 4. Waste heat recovery and preheating energy saving: The waste heat drying mechanism utilizes corrugated heat exchange tubes to heat the drying gas and preheat the down in the feeding cylinder. This reduces the condensation rate when high-temperature steam comes into contact with cold down, thereby minimizing the impact of steam humidity on the down and achieving cascaded energy utilization.
[0028] 5. Adjustable temperature intake protection: The temperature control mechanism condenses the discharged steam into liquid via a spiral condenser tube, which is then injected into the temperature control cylinder as a cooling medium. The position of the piston plate can be adjusted by rotating the rotating ring, changing the contact length between the cooling liquid and the inlet pipe, thereby precisely regulating the temperature of the high-temperature steam entering the equipment. This prevents excessively high temperatures from damaging soft down feathers and improves the equipment's adaptability to different types of down feathers. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0032] Reference Figure 1-7A down antibacterial treatment device and method based on high-temperature steam includes a fixed cylinder 1, a feeding cylinder 4 fixedly installed on the top of the fixed cylinder 1, the feeding cylinder 4 being interconnected with the fixed cylinder 1, a feeding hopper 5 installed on the top of the feeding cylinder 4, a collection box 3 installed at the bottom of the fixed cylinder 1, two conical hoppers 2 installed on the fixed cylinder 1, an exhaust ring 11 installed on the top of the upper conical hopper 2, and an air inlet pipe 10 installed on one side of the fixed cylinder 1. The adaptive antibacterial mixing mechanism 6 includes an active tube 61, which is rotatably installed inside a fixed cylinder 1. A positioning box 65 is fixedly installed at one end of an air inlet pipe 10. The positioning box 65 is rotatably connected to the active tube 61, and the active tube 61 and the positioning box 65 are interconnected. The feeding mechanism 7 includes two isolation plates 71 and two adjusting plates 72. The two isolation plates 71 are fixedly installed on the inner wall of the feeding cylinder 4, and the two adjusting plates 72 are rotatably installed at the bottom of the isolation plates 71. The waste heat drying mechanism 8 includes a heat exchange box 81, which is fixedly installed on one side of the feeding cylinder 4, and a connecting pipe 12 is installed at the bottom of the heat exchange box 81, which is connected to the exhaust ring 11. The temperature control mechanism 9 includes a temperature control cylinder 91, which is fixedly installed on the outside of the air inlet pipe 10, and a drain pipe 93 is installed on the outside of the temperature control cylinder 91.
[0033] Reference Figure 2 and Figure 3The adaptive antibacterial mixing mechanism 6 also includes two agitated nozzles 63, which are fixedly installed at the bottom of the active pipe 61 and connected to it. The air outlets of the agitated nozzles 63 are offset upwards at a 30-degree angle in the vertical direction of the active pipe 61. Three fixing rods 66 are fixedly installed on the inner wall of the fixing cylinder 1 and are fixedly connected to the positioning box 65. Two sets of drive nozzles 62 are installed on the active pipe 61, with two nozzles in each set. Both sets of drive nozzles 62 are located inside the conical hopper 2. The air outlets of the drive nozzles 62 are set at a 30-degree angle to the tangent of the active pipe 61. Two stirring rods 64 are fixedly installed on the active pipe 61 and cooperate with the feeding cylinder 4. The high-temperature steam in the active pipe 61 is circulated through the agitated nozzles 63. The steam is sprayed out and the outlet of the agitator nozzle 63 is offset at a 30-degree angle to the vertical direction of the active tube 61. This causes the steam sprayed from the agitator nozzle 63 to blow the down feathers above, reducing the speed at which the down feathers fall. At the same time, it can also fully sterilize the down feathers at high temperature. The setting of the fixing rod 66 can facilitate the positioning box 65 and the active tube 61 to be limited. By setting the outlet of the drive nozzle 62 at a 30-degree angle to the tangent of the active tube 61, the drive nozzle 62 can push the active tube 61 to rotate through the reverse force of the steam when it sprays steam. This will drive the drive nozzle 62 to blow the down feathers laterally and perform a lateral sterilization operation. At the same time, the setting of the drive nozzle 62 inside the conical hopper 2 can ensure that the steam sprayed by the drive nozzle 62 can be fully mixed with the down feathers in the conical hopper 2, increasing the sterilization effect.
[0034] Reference Figure 5 The feeding mechanism 7 also includes two through holes 73, which are respectively opened on the two isolation plates 71. The adjusting plate 72 is provided with a connecting hole 74, which cooperates with the corresponding through hole 73. Both adjusting plates 72 are fixedly connected to the active pipe 61, and the active pipe 61 is rotatably connected to the two isolation plates 71. The down is fed from above by communicating with the through holes 73 on the isolation plates 71 and the through holes 73 on the adjusting plates 72. At the same time, the connecting holes 74 on the two adjusting plates 72 are staggered, so that when the two adjusting plates 72 rotate synchronously, they can intermittently seal the down on the feeding hopper 5 to prevent the leakage of residual heat steam.
[0035] Reference Figure 4The waste heat drying mechanism 8 also includes two corrugated heat exchange tubes 83, which are connected to the feeding cylinder 4 and located between two isolation plates 71. A blower 82 is installed on one side of the heat exchange box 81, which is connected to the two corrugated heat exchange tubes 83. Through the arrangement of the two corrugated heat exchange tubes 83, the discharged steam can be heat exchanged, thereby heating the dry gas in the corrugated heat exchange tubes 83 and preheating the down in the feeding cylinder 4, reducing the condensation rate of the steam when the down comes into contact with the steam, and thus reducing the humidity when the steam comes into contact with the down.
[0036] Reference Figure 6 The temperature control mechanism 9 also includes a spiral condenser tube 92, which is fixedly sleeved on the outside of the fixed cylinder 1, and the top end of the spiral condenser tube 92 is connected to the bottom of the heat exchange box 81. The temperature control mechanism 9 also includes a piston plate 94, which is slidably installed on the inner wall of the temperature control cylinder 91, and the bottom end of the spiral condenser tube 92 and the drain pipe 93 are located on the same side of the piston plate 94. The piston plate 94 is slidably connected to the air inlet pipe 10. A rotating ring 96 is rotatably connected to the outside of the temperature control cylinder 91. Two push rods 95 are fixedly installed on one side of the piston plate 94, and the rotating ring 96 is drivenly connected to the two push rods 95. Two positioning gears 97 are rotatably connected to one side of the temperature control cylinder 91, and the positioning gears 97 are threadedly connected to the corresponding push rods 95. An internal gear ring 98 is fixedly installed on the inner side of the rotating ring 96, and the internal gear ring 98 is threadedly connected to the two positioning gears 97. The spiral condenser tube 92 further cools the steam discharged from the heat exchanger 81, forming liquid that is injected into the temperature regulating cylinder 91. Rotating the rotating ring 96 causes the internal gear ring 98 to rotate. The internal gear ring 98 meshes with two positioning gears 97, which in turn rotate the two positioning gears 97. The positioning gears 97 are threadedly connected to the push rod 95, which in turn moves the piston plate 94, thereby adjusting the temperature of the intake pipe 10. The piston plate 94 adjusts the length of the liquid within the temperature regulating cylinder 91, thus adjusting the contact time between the intake pipe 10 and the cooling liquid in the temperature regulating cylinder 91, thereby regulating the intake temperature of the intake pipe 10 and preventing excessively high temperatures that could damage softer down feathers.
[0037] A method of using a down antibacterial treatment device based on high-temperature steam includes the following steps: S1. Down feathers enter the feeding cylinder 4 through the feeding hopper 5. High-temperature steam enters the active pipe 61 through the air inlet pipe 10 and the positioning box 65. The high-temperature steam in the active pipe 61 is sprayed out through the agitator nozzle 63. The outlet of the agitator nozzle 63 is offset at a 30-degree angle in the vertical direction of the active pipe 61, so that the steam sprayed by the agitator nozzle 63 blows the down feathers above, reducing the speed at which the down feathers fall. At the same time, it can also fully sterilize the down feathers at high temperature. The setting of the fixing rod 66 makes it easy to... The positioning box 65 limits the movement of the active tube 61. The air outlet of the drive nozzle 62 is set at a 30-degree angle to the tangent of the active tube 61. When the drive nozzle 62 sprays air, the reverse force of the steam pushes the active tube 61 to rotate, thereby driving the drive nozzle 62 to blow the down laterally and perform lateral sterilization. At the same time, the drive nozzle 62 is located inside the conical hopper 2, which allows the steam sprayed by the drive nozzle 62 to be fully mixed with the down in the conical hopper 2, increasing the sterilization effect. S2. The rotating active tube 61 drives the two adjusting plates 72 to rotate, and the adjusting plates 72 drive the connecting holes 74 to rotate. The through holes 73 on the isolation plate 71 are connected to the through holes 73 on the adjusting plate 72, so as to discharge the down above. At the same time, the connecting holes 74 on the two adjusting plates 72 are staggered, so that when the two adjusting plates 72 rotate synchronously, they can intermittently seal the down on the feeding hopper 5 to prevent the leakage of steam with residual heat. S3. After sterilization, the steam in the fixed cylinder 1 is discharged through the exhaust ring 11 and introduced into the heat exchange box 81 through the connecting pipe 12. The two corrugated heat exchange tubes 83 can exchange heat with the discharged steam, so that the dry gas in the corrugated heat exchange tubes 83 is heated and the down in the feeding cylinder 4 is preheated, reducing the condensation rate of the steam when the down comes into contact with the steam, thereby reducing the humidity when the steam comes into contact with the down. The spiral condenser 92 (S4) further cools the steam discharged from the heat exchanger 81 and forms liquid that is injected into the temperature regulating cylinder 91. Rotating the rotating ring 96 causes the internal gear ring 98 to rotate. The internal gear ring 98 meshes with two positioning gears 97, thereby causing the two positioning gears 97 to rotate. The positioning gears 97 are threadedly connected to the push rod 95, which in turn causes the piston plate 94 to move, thereby adjusting the temperature regulation effect on the air inlet pipe 10. The piston plate 94 adjusts the length of the liquid in the temperature regulating cylinder 91, thereby adjusting the contact time between the air inlet pipe 10 and the cooling liquid in the temperature regulating cylinder 91, thus regulating the air inlet temperature of the air inlet pipe 10 and preventing excessively high temperatures that could damage softer down feathers.

At the same time, the connecting holes (74) on the two adjusting plates (72) are staggered, so that when the two adjusting plates (72) rotate synchronously, they can intermittently seal the down on the feeding hopper (5) to prevent the leakage of steam with residual heat. S3. After sterilization, the steam in the fixed cylinder (1) is discharged through the exhaust ring (11) and introduced into the heat exchange box (81) through the connecting pipe (12). Through the setting of two corrugated heat exchange tubes (83), the discharged steam can be heat exchanged, so that the dry gas in the corrugated heat exchange tube (83) is heated and the down in the feeding cylinder (4) is preheated, reducing the condensation rate of the steam when the down comes into contact with the steam, thereby reducing the humidity when the steam comes into contact with the down. The installation of the spiral condenser (92) in S4 can further cool the steam discharged from the heat exchange box (81) and form liquid that is injected into the temperature regulating cylinder (91). Rotating the rotating ring (96) drives the internal gear ring (98) to rotate. The internal gear ring (98) meshes with the two positioning gears (97), thereby driving the two positioning gears (97) to rotate. The positioning gears (97) are connected to the push rod (95) by threads, thereby driving the piston plate (94) to move in position, thereby adjusting the temperature regulation effect on the air inlet pipe (10). By setting the piston plate (94), the length of the liquid in the temperature regulating cylinder (91) can be adjusted, thereby adjusting the contact time between the air inlet pipe (10) and the cooling liquid in the temperature regulating cylinder (91), thereby adjusting the air inlet temperature of the air inlet pipe (10) to prevent the temperature from being too high, which may easily damage some softer down when dealing with different types of down.
