Description

Technical Field

[0001] This invention relates to the field of down processing, and more specifically to a down steam sterilization device. Background Technology

[0002] Down, as a natural insulating material, requires thorough sterilization before processing to ensure safe use. Currently, down sterilization primarily involves two methods: chemical soaking and steam sterilization. The latter, which leaves no chemical residue, is considered safer and more environmentally friendly and is therefore widely used. However, traditional down steam sterilization devices typically process large quantities of down at once. This method, processing excessive amounts at once, not only reduces the quality of sterilization and extends the sterilization cycle, decreasing continuous production efficiency, but also places a heavy load on the device, affecting its lifespan. Therefore, we propose a down steam sterilization device. Summary of the Invention

[0003] The purpose of this invention is to provide a down steam sterilization device, which solves the technical problem that existing down steam sterilization devices usually place a large amount of down into the device for steam treatment at once. This treatment method not only reduces the quality of down sterilization and sterilization and prolongs the single sterilization cycle, thus reducing the efficiency of continuous production, but also leads to a large load on the device and affects its service life.

[0004] The present invention achieves the above objectives through the following technical solutions: A down steam sterilization device includes a hopper, a material control mechanism connected to the bottom of the hopper, and a sterilization mechanism connected to the bottom of the material control mechanism. The sterilization mechanism has a mixing section for introducing high-temperature steam and stirring the down. The material control mechanism includes a shell, a rotating material control roller inside the shell, an inlet and an outlet respectively located on both sides of the shell and connected to the hopper and the sterilization mechanism, and two sets of symmetrically arranged material troughs on the outer wall of the material control roller. The material troughs sequentially connect with the inlet and outlet when the material control roller rotates to quantitatively deliver down. The sterilization mechanism is connected to a material trough through a gas treatment component. The gas treatment component is used to treat the high-temperature steam in the sterilization mechanism and then add atomized ionic liquid to preheat the down in the material trough.

[0005] A further improvement is that the hopper is provided with an arc-shaped guide plate, and the bottom of the guide plate is provided with a vertically connected guide pipe, and the guide pipe is provided with a solenoid valve. The material control mechanism also includes a sealing plate horizontally inserted on one side of the feed inlet for closing the feed inlet. A weighing device is embedded on the top of the outer wall of the sealing plate inside the feed inlet. One end of the sealing plate is connected to a telescopic device located on the side wall of the feed inlet. The sealing plate is driven by the telescopic device to move horizontally to open or close the feed inlet. The weighing device is used to detect the weight of down falling from the guide tube onto its bearing surface in real time. When the weight of down reaches a preset value, a signal is sent to an external controller, which then controls the solenoid valve to close.

[0006] A further improvement is that the mixing section is located inside the processing shell, and the mixing section includes a hollow rotating rod located at the axis of the processing shell. One end of the hollow rotating rod is connected to the output end of the rotating device two. The rotating device two is mounted inside the discharge port via a bracket. The outer circumference of the hollow rotating rod is provided with several interconnected hollow support rods arranged in a circular array from top to bottom. The outer wall of the hollow support rod is uniformly provided with through holes for discharging high-temperature steam. The other end of the hollow rotating rod is rotatably connected to a connecting pipe, and the other end of the connecting pipe is connected to the output end of the device that supplies high-temperature steam.

[0007] A further improvement is that a rotating device for driving the control roller is provided on one side of the housing. A blind hole is axially opened on the side of the control roller away from the rotating device. A rod is coaxially inserted into the blind hole. One end of the rod extends outward and penetrates the housing, and the other end is connected to a ring through a bracket. The ring is rotatably connected to the inner wall of the blind hole. A matching plate is attached to the bottom of the material trough. An elastic telescopic rod is connected to the side of the plate facing the bottom of the trough. One end of the elastic telescopic rod extends into the blind hole and is fitted with a support frame. One end of the support frame extends into the inner side of the ring, and a magnetic roller is rotatably provided on the side of the support frame facing the inner wall of the ring. An electromagnetic block is embedded at the bottom of the inner wall of the ring. The electromagnetic block is used to attract the magnetic roller in the material trough below downward when energized, so that the corresponding elastic telescopic rod drives the plate downward.

[0008] A further improvement is that the rod body includes a hollow rod, one end of which is connected to a connector. The connector is connected to a ring body via a bracket. The end of the elastic telescopic rod away from the plate body is slidably connected to the outer circumferential wall of the connector via an arc-shaped slider. The top of the connector has a through hole communicating with its inner cavity. The inner cavity of the elastic telescopic rod is a hollow structure, with one end communicating with the inner cavity of the plate body and the other end passing through the arc-shaped slider to communicate with the through hole on the connector head. The side of the plate body away from the material trough body has evenly distributed ventilation holes. The end of the hollow rod away from the connector is connected to the processing shell via a gas processing component.

[0009] A further improvement is that the gas processing component includes a heat exchanger, the first inlet end of which is connected to the processing shell through an exhaust pipe, the second inlet end of which is connected to an external gas supply device through an inlet pipe, the first outlet end of which is connected to an external filtration device through a pipe, and the second outlet end of which is connected to the end of the hollow rod away from the connector through a connecting pipe. A liquid supply device for supplying atomized ionic aqueous solution is connected to the connecting pipe.

[0010] A further improvement is that a detection sensor for detecting gas temperature is installed in the connecting gas pipe, a valve body for controlling gas flow is installed on the exhaust pipe, and a heating device is installed on the intake pipe. The detection sensor, valve body, and heating device are all electrically connected to an external controller.

[0011] A further improvement is that a vent hole penetrating the control roller is provided on one side of the material trough, and a connecting pipe is inserted into the outer wall of the housing. One end of the connecting pipe extends into the housing and is configured to form a sealed connection with the vent hole of the material trough when the control roller rotates to align with the feed inlet. The other end of the connecting pipe is used to connect with external filtration equipment.

[0012] The beneficial effects of this invention are as follows: The down steam sterilization device of the present invention, by setting up a material control mechanism consisting of a control roller, a material trough and a rotating device, can realize intermittent quantitative feeding of down, ensuring that the amount of down entering the sterilization mechanism each time is accurately controllable, effectively preventing problems such as down accumulation and uneven steam penetration caused by excessive feeding at one time, improving the thoroughness and consistency of sterilization, and avoiding high-load operation of the device while ensuring excellent sterilization effect, thus extending the service life of the device. Secondly, this device is also equipped with a gas handling unit, which can treat the high-temperature steam in the sterilization unit and add it to the atomized ionic liquid to preheat the down in the material tank. On the one hand, this allows the temperature of the down to rise slowly, effectively avoiding the instantaneous shrinkage of down fibers and the aggravated thermal denaturation of proteins caused by excessive temperature difference when the down directly enters the high-temperature sterilization environment. This prevents problems such as down clumping, decreased loft, and heat damage. On the other hand, it allows the ions in the atomized ionic liquid to evenly adhere to the surface of the down fibers during the preheating stage, forming a protective layer. This effectively protects the down fibers and enhances their heat resistance during the subsequent high-temperature steam sterilization operation, achieving a synergistic effect of sterilization and down protection.

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1

[0017] Please see the appendix Figure 1-5 A down steam sterilization device includes a hopper 100. In this embodiment, the top of the hopper 100 is hollow and used to load down to be sterilized. The bottom of the hopper 100 is connected to a material control mechanism 200, and the bottom of the material control mechanism 200 is connected to a sterilization mechanism 300. This device controls the amount of down entering the sterilization mechanism 300 through the material control mechanism 200, avoiding the accumulation or insufficiency of down during the processing, ensuring the uniformity and consistency of sterilization, and effectively reducing the processing load of the sterilization mechanism 300, ensuring the stable operation of the equipment and the safety of the processing work. In this embodiment, the disinfection and sterilization mechanism 300 includes a processing shell 301, and the processing shell 301 is provided with a mixing section for introducing high-temperature steam and stirring the down. Preferably, the material control mechanism 200 includes a housing 201 (in this embodiment, the processing housing 301 has a circular vertical cross-section), a material control roller 202 rotatably disposed within the housing 201, the outer diameter of which is adapted to the inner diameter of the processing housing 301, and two material control troughs 205 and 205 respectively disposed on both sides of the housing 201 and connected to the hopper 100 and the sterilization mechanism 300, respectively; a rotating device 204 (composed of a servo motor and a reducer) disposed on one side of the housing 201 for driving the material control roller 202 to rotate; and two sets of symmetrically arranged material troughs 203 on the outer wall of the material control roller 202. When the rotating device 204 drives the material control roller 202 to rotate, the material troughs 203 sequentially connect with the inlet 205 and the outlet to quantitatively deliver the material. Down is fed by a rotating device 204 that drives a control roller 202 to rotate at a constant speed within the housing 201. When a certain trough 203 rotates to the top and aligns with the inlet 205, it receives down of a fixed volume from the hopper 100. As the control roller 202 continues to rotate, the trough 203 disengages from the inlet 205 and is sealed and transported until it rotates to align with the outlet. At this point, the down it contains is unloaded into the sterilization and disinfection mechanism 300, thus achieving an intermittent and quantitative feeding process. The sterilization and disinfection mechanism 300 is connected to a trough 203 via a gas treatment component 400. The gas treatment component 400 is used to treat the high-temperature steam in the sterilization and disinfection mechanism 300 and add atomized ionic liquid, which is then transported to the trough 203 to preheat the down.

[0018] Preferably, in this embodiment, the hopper 100 is provided with an arc-shaped guide plate 101, and the down in the hopper 100 is located above the arc-shaped guide plate 101, which guides the down in the hopper 100. The bottom of the guide plate 101 is vertically provided with a connected guide pipe, and a solenoid valve is provided in the guide pipe. The material control mechanism 200 also includes a sealing plate 206 horizontally inserted into one side of the feed inlet 205 for closing the feed inlet 205. In this embodiment, the sealing plate 206 has an L-shaped vertical cross-section, and its length is slightly greater than the length of the feed inlet 205. A weighing device 207 is embedded in the top of the outer wall of the sealing plate 206 inside the feed inlet 205. In this embodiment, the weighing device 207 can be, for example, a pressure sensor. One end of the sealing plate 206 is connected to a telescopic device 208 (such as an electric telescopic rod) located on the side wall of the feed inlet 205. 206 is driven by the telescopic device 208 to move horizontally to open or close the feed port 205. In this embodiment, the sealing plate 206 always closes the feed port 205 when not unloading, effectively preventing the subsequent preheated gas from escaping upward. The weighing device 207 is used to detect the weight of the down falling from the guide pipe onto its bearing surface in real time. When the weight of the down reaches the preset value, it sends a signal to the external controller, which controls the solenoid valve to close. That is, in this embodiment, both the weighing device 207 and the solenoid valve are electrically connected to the external controller. When started, the solenoid valve opens, and the down in the hopper 100 falls into the feed inlet 205 through the guide pipe and accumulates on the weighing device 207. The weighing device 207 detects the weight in real time. When the preset value is reached, it sends a signal to the controller. The controller then closes the solenoid valve to stop feeding. Then, the telescopic device 208 is activated to pull the sealing plate 206 to open the feed inlet 205, so that the weighed down falls into the corresponding feed trough 203 below. Then, the control roller 202 rotates a certain angle (such as 180°) to move the full feed trough 203 away and align the empty feed trough 203 with the feed inlet 205. After the sealing plate 206 is reset and closed, the next weighing cycle feeding can begin.

[0019] Preferably, the mixing section of this embodiment includes a hollow rotating rod 303 located at the axis of the processing shell 301. One end of the hollow rotating rod 303 is connected to the output end of the rotating device 302. The rotating device 302 in this embodiment includes a protective shell and a motor disposed inside the protective shell. The rotating device 302 is disposed in the discharge port by a bracket. The outer circumference of the hollow rotating rod 303 is provided with several interconnected hollow support rods 304 arranged in a ring array from top to bottom. The outer wall of the hollow support rod 304 is uniformly provided with through holes for discharging high-temperature steam. These through holes are small through holes. The other end of the hollow rotating rod 303 can be rotatably connected to a connecting pipe 305 through a rotary joint. The other end of the connecting pipe 305 is connected to the output end of a device that supplies high-temperature steam, such as a steam generator. The high-temperature steam generated by the equipment for supplying high-temperature steam is continuously input into the rotating hollow rod 303 through the connecting pipe 305, and then distributed to the hollow support rods 304 of each layer. Finally, it is sprayed and diffused into the processing shell 301 in a multi-angle and three-dimensional manner through the through holes on the outer wall of the hollow support rods 304. At the same time, the rotating device 2 302 drives the hollow rod 303 to drive all the hollow support rods 304 to rotate at a uniform speed, continuously stirring the down in the processing shell 301, so that the down can fully contact the high-temperature steam for disinfection and sterilization during dynamic tumbling. It should be noted that the bottom of the processing shell 301 has a discharge port for discharging the sterilized down feathers, and a valve body is installed inside the discharge port.

[0020] Example 2

[0021] Please see the appendix Figure 2-6A blind hole is axially formed on the side of the control roller 202 away from the rotating device 204. A rod is coaxially inserted into the blind hole. One end of the rod extends outward and penetrates the housing 201, while the other end is connected to the ring 213 via a bracket. In this embodiment, the rod is fixed to the housing 201, and the ring 213 is rotatably connected to the inner wall of the blind hole via a bearing. A matching plate 210 is attached to the bottom of the material trough 203. An elastic telescopic rod 212 is connected to the side of the plate 210 facing the bottom of the trough. In this embodiment, the elastic telescopic rod 212 specifically consists of a sleeve rod connected to the plate 210 at one end, a movable rod inserted at the other end of the sleeve rod, and... A compression spring is sleeved on the outside of the movable rod and connected to the sleeve rod and the movable rod at both ends respectively. One end of the elastic telescopic rod 212 extends into the blind hole and is sleeved with a support frame. Specifically, the support frame is fixedly sleeved on the end of the sleeve rod away from the plate 210. One end of the support frame extends into the inner space of the ring 213, and a magnetic roller 214 made of magnetic material is rotatably provided on the side of the support frame facing the inner wall of the ring 213. An electromagnetic block is embedded at the bottom of the inner wall of the ring 213. The electromagnetic block is used to attract the magnetic roller 214 in the lower material trough 203 downward when energized, so that the corresponding elastic telescopic rod 212 drives the plate 210 downward. When the control roller 202 rotates under the drive of the rotating device 204, it drives the internal support frame and magnetic roller 214 to perform circumferential motion in the inner space of the ring 213. When a certain material trough 203 on the control roller 202 rotates to align with the discharge port, the magnetic roller 214 corresponding to the material trough 203 also moves to the position directly opposite the electromagnetic block at the bottom of the inner wall of the ring 213. At this time, the control electromagnetic block is energized to attract the magnetic roller 214 to move downward, thereby pulling the corresponding elastic telescopic rod 212 through the support frame to drive the plate 210 to move downward, completely pushing out the down that may be attached to the material trough 203 due to static electricity, so that it is completely discharged from the discharge port.

[0022] Preferably, the rod body in this embodiment includes a hollow rod 209. Both ends of the hollow rod 209 are hollow, and one end of the hollow rod 209 is connected to a connector 211. The connector 211 in this embodiment consists of a hollow cylinder at one end and annular protrusions fixedly fitted onto both sides of the outer wall of the cylinder. The connector 211 is connected to a ring 213 via a bracket. The end of the elastic telescopic rod 212 away from the plate 210 is slidably connected to the outer circumference of the connector 211 via an arc-shaped slider 217. Specifically, one end of the movable rod of the elastic telescopic rod 212 is fixedly fitted with the arc-shaped slider 217, and one side of the arc-shaped slider 217 is attached to the cylinder of the connector 211. The outer circumference of the slider 217 is located between the annular protrusions on both sides. The opposite surfaces of the annular protrusions on both sides are provided with annular grooves. The side wall of the arc slider 217 extends with an arc block that is embedded in the annular groove. This structure allows the control roller 202 to drive the elastic telescopic rod 212 to rotate stably along the outer wall of the connector 211 when it rotates. When the electromagnetic block is energized and attracts the magnetic roller 214, only the sleeve of the elastic telescopic rod 212 moves relative to the movable rod, while the connection position of the movable rod and the arc slider 217 with the connector 211 remains unchanged. To further ensure the sealing, a rubber sealing strip can be embedded on the outer wall of the arc slider 217 facing the connector 211. The connector 211 has a through hole at its top that communicates with its inner cavity. The elastic telescopic rod 212 has a hollow inner cavity, with one end communicating with the inner cavity of the plate 210 and the other end passing through the arc-shaped slider 217 to communicate with the through hole on the connector 211. That is, both ends of the sleeve rod and the movable rod in the elastic telescopic rod 212 are hollow. The plate 210 has evenly spaced ventilation holes 216 on the side away from the material trough 203. The hollow rod 209 has one end away from the connector 211 that communicates with the treatment shell 301 through the gas treatment component 400. When the sterilization mechanism 300 is performing high-temperature steam treatment on the down, the weighing device 207, the sealing plate 206, and the telescopic device 208 cause the weighed down down to fall into the material trough 203 above. Then, the telescopic device 208 controls the sealing plate 206 to reset and close. The high-temperature steam generated by the sterilization mechanism 300 during the sterilization process generates... After being treated by the gas treatment component 400, some of the high-temperature steam is guided into the hollow rod 209, then flows into the connector 211, and then enters the elastic telescopic rod 212 and the inner cavity of the plate 210 associated with the feed trough 203, which is currently loaded with down and corresponds to the feed inlet 205. Finally, it is evenly discharged from the vent holes 216 on the plate 210 into the down in the feed trough 203, thereby preheating the down. This method recovers the heat energy of the high-temperature steam generated during the sterilization process and uses it directly for preheating the down in subsequent batches, improving the thermal efficiency of the system and reducing the overall energy consumption. It also allows the temperature of the down to rise gradually, effectively avoiding the instantaneous shrinkage of down fibers and the aggravated thermal denaturation of proteins caused by excessive temperature difference when the down directly enters the high-temperature sterilization environment. This prevents problems such as down clumping, decreased loft, and heat damage caused by these issues.

[0023] Preferably, the gas handling component 400 in this embodiment includes a heat exchanger 403 (a conventional structure in the art, which will not be described in detail here). The first inlet end of the heat exchanger 403 is connected to the processing shell 301 through an exhaust pipe 406 for introducing high-temperature steam that has undergone sterilization. Its second inlet end is connected to an external air supply device (composed of a negative pressure fan and a filter) through an inlet pipe 405 for introducing clean room temperature air. The first outlet end of the heat exchanger 403 is connected to an external filtration device (a conventional structure in the art, which will not be described in detail here) through a pipe for final treatment and discharge of the cooled high-temperature steam. The second outlet end of the heat exchanger 403... The end of the hollow rod 209, away from the connector 211, is connected via a connecting pipe 401. A liquid supply device 407 for supplying the atomized ionic aqueous solution is connected to the connecting pipe 401. Optionally, the atomized ionic aqueous solution in this embodiment is a low-concentration zinc ion aqueous solution, preferably a diluted aqueous solution of zinc citrate. The liquid supply device 407 includes, for example, a corrosion-resistant tank for storing the atomized ionic aqueous solution, a solenoid valve for opening and closing control located on the outlet pipe of the tank, a metering pump or proportional valve for precisely adjusting the flow rate, and an atomizing nozzle (such as an ultrasonic atomizer or a fine pressure nozzle) connected to the end of the pipe and supplying the atomized ionic aqueous solution to the connecting pipe 401. After the high-temperature steam has been sterilized in the sterilization unit 300, it is extracted and introduced into the heat exchanger 403 through the exhaust pipe 406. At the same time, clean room temperature air enters the heat exchanger 403 through the air inlet pipe 405. The two exchange heat in the heat exchanger 403. After the high-temperature steam is cooled, it is filtered by the external filter and then safely discharged. The heated air is transported through the connecting air pipe 401. During the transport process, a predetermined amount of atomized ionized water solution is supplied to the connecting air pipe 401 through the liquid supply device 407 so that it mixes with the heated air and enters the hollow rod 209 to preheat the down in the corresponding material tank 203. It should be noted that exhaust fans and other equipment can also be installed on the above-mentioned pipelines, which will not be described in detail here.

[0024] Preferably, the connecting gas pipe 401 in this embodiment is provided with a detection sensor 402 for detecting gas temperature. The detection sensor 402 in this embodiment can be a temperature detection sensor. The exhaust pipe 406 is provided with a valve body for controlling gas flow. Optionally, the valve body in this embodiment is a regulating valve. The intake pipe 405 is provided with a heating device 404. The heating device 404 in this embodiment can be a heating wire or an electric heater. The detection sensor 402, the valve body and the heating device 404 are all electrically connected to an external controller.

[0025] The external controller receives the actual temperature value of the preheated gas from the detection sensor 402 and compares it with the preset preheating temperature value. It dynamically outputs instructions through the built-in PID control algorithm. If the preheated gas temperature is lower than the preheating temperature value, the external controller starts the heating device 404 to provide auxiliary heating for the clean room temperature air. If the preheated gas temperature is lower than the preheating temperature value, the external controller adjusts the valve body to increase the flow rate of high-temperature steam, ensuring the uniformity and consistency of the down preheating effect.

[0026] Preferably, in this embodiment, the material trough 203 is provided with an exhaust hole 218 that passes through the control roller 202 on one side, and a connecting pipe 215 is inserted into the outer wall of the housing 201. One end of the connecting pipe 215 extends into the housing 201 and is configured to form a sealed communication with the exhaust hole 218 of the material trough 203 when the control roller 202 rotates to align with the feed inlet 205. The other end of the connecting pipe 215 is used to connect to external filtration equipment. In this embodiment, valve bodies and fan-type equipment can be installed on the connecting pipe 215. When a feed trough 203 on the control roller 202 rotates to the top and aligns with the feed inlet 205 to receive or temporarily store the weighed down, the exhaust port 218 of the feed trough 203 is connected to one end of the connecting pipe 215. At this time, preheating gas is introduced into the feed trough 203 to preheat the down. By opening the valve in the connecting pipe 215, the preheating gas in the feed trough 203 can enter the external filtration equipment through the exhaust port 218 and the connecting pipe 215 for purification before being discharged, thus ensuring the preheating effect of the down.

[0027] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
