Description

Technical Field

[0001] This utility model relates to the field of down production technology, specifically to a sterilization and mite removal device for down products. Background Technology

[0002] Down processing refers to the production activity of processing the feathers of poultry such as geese and ducks into standard down. The quality of down that is usually purchased varies greatly due to seasonality and breed. In order to make full use of the down and improve economic benefits, it is necessary to process, clean, remove impurities and sterilize at high temperature.

[0003] Patent document CN210728248U discloses a sterilization and mite-removal device for down products. It uses a heating device to heat and evaporate liquid water at high temperatures. The steam from this high-temperature evaporation flows through vents on a hood to a tray, thus sterilizing and removing mites from the down inside the tray. However, because down is lightweight, using a tray with an open top makes it easy for down to escape from the tray when it is placed inside the outer cylinder. Furthermore, prolonged contact between the down in the upper tray and the high-temperature steam can damage the down in the lower tray.

[0004] Patent document CN215938428U discloses a high-temperature sterilization device for raw materials used in down processing. The device includes a first chute, a slide rod, a sterilization tank, a cylinder, a first connecting rod, a rack, a gear, a second connecting rod, a connecting block, a connecting groove, a connecting plate, and a slider. By pulling the first support plate, the slide rod slides within the first chute, causing the first support plate to move the sterilization tank, removing it from the sterilization boiler body. Down to be sterilized is then placed into the sterilization tank, and the sterilization boiler cover is closed by pushing the tank in. The cylinder is then activated, and its output pushes the first connecting rod, which in turn moves the connecting block. Simultaneously, the slider slides within the second chute, and the gear rotates on the rack. This rotation drives the second connecting rod to rotate, which in turn rotates the connecting plate within the connecting groove, causing the down in the sterilization tank to tumble. This equipment can sterilize a large amount of down. However, after the down is turned over in the sterilization tank, if high-temperature steam is used to sterilize the down, the down tends to clump together after contact with water, which prevents the high-temperature steam from effectively contacting the down. Utility Model Content

[0005] The main purpose of this invention is to provide a sterilization and mite removal device that can improve the efficiency of sterilizing and removing mites from down feathers, and facilitate the removal of down feathers for subsequent drying operations.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: A sterilization and mite removal device for down products includes a housing with an open top. One end of the housing is fixedly connected to an outlet pipe. Multiple storage boxes are snapped into the housing and arranged sequentially in a left-right direction within the housing. A lower pipe is slidably disposed within the housing below the storage boxes. A vertical pipe is fixedly connected to the lower pipe on both sides of the storage boxes. Multiple nozzles are installed on the side of the vertical pipe facing the storage box. The movement direction of the lower pipe and the vertical pipe is parallel to the front-back direction of the housing. A drive assembly is provided on the housing, which can drive the lower pipe and the vertical pipe to move in the front-back direction of the housing. A cable chain is installed inside the housing. One end of the cable chain is fixedly connected to the lower pipe, and the other end of the cable chain is fixedly connected to the housing. A flexible hose is disposed inside the cable chain. One end of the flexible hose is connected to the lower pipe, and the other end of the flexible hose is connected to an inlet pipe fixed on the housing. A rectangular groove is opened on the side of the storage box facing the vertical pipe, and a filter screen is fixed in the rectangular groove. A down filling pipe is fixedly connected to the top of the storage box.

[0007] Specifically, the inner sides of the front and rear sidewalls of the housing are provided with multiple slots, the number of slots on the front and rear sides are equal and correspond one-to-one, the front and rear ends of the storage box are respectively engaged in the two corresponding slots, and multiple rollers are installed on the front and rear ends of the storage box.

[0008] Specifically, the bottom plate of the housing has multiple sliding grooves, the length direction of which is parallel to the front-rear direction of the housing. Each sliding groove has a slider that is slidably engaged in it, and the slider is fixedly connected to the lower tube.

[0009] Specifically, the hose is a pressure-resistant and high-temperature-resistant hose.

[0010] Specifically, the drive assembly includes a reciprocating screw rotatably connected to the housing. A connecting sleeve is fitted on the reciprocating screw portion inside the housing. The connecting sleeve, the balls inside the connecting sleeve, and the reciprocating screw constitute a ball screw pair. The connecting sleeve is fixedly connected to the lower tube. A motor is fixedly mounted on the outside of the housing. The output shaft of the motor is concentrically fixedly connected to the reciprocating screw.

[0011] Specifically, a cover plate is hinged to the upper end of the housing.

[0012] Specifically, the down filling tube is threaded with an end cap.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. A reciprocating screw driven by a motor causes the riser with nozzles to move back and forth along the length of the storage box, ensuring that high-temperature steam penetrates the filter and evenly covers all areas of the down layer. During the movement of the nozzles, the steam contacts different parts of the down in sequence, avoiding localized continuous heating that could damage the fibers, and eliminating blind spots in static processing.

[0014] 2. The storage boxes are installed using a combination of slots and rollers in a "push-in" manner. Combined with the open design of the casing, this facilitates batch filling and removal of down feathers. Multiple storage boxes are arranged side by side to form an independent processing unit, supporting continuous production. For example, other storage boxes can be loaded and unloaded simultaneously while one box is being processed, significantly improving production line efficiency.

[0015] 3. The threaded end cap of the down filling tube locks in the down during transport and drying, preventing fiber loss. The top outlet pipe of the shell automatically discharges excess steam to prevent internal pressure buildup; the bottom drain pipe promptly removes condensate.

[0016] 4. The cable chain is embedded with a pressure-resistant and high-temperature-resistant hose to maintain a stable steam delivery during the reciprocating motion of the riser, preventing pipe entanglement or wear and leakage. The nozzle sprays directly onto the filter area of ​​the storage box, concentrating the steam to penetrate the down layer, reducing ineffective dissipation and improving thermal energy utilization efficiency.

[0017] 5. The hinged cover at the top of the housing provides a panoramic maintenance access, and the sliding block mechanism allows the lower tube to be pulled out as a whole, facilitating nozzle cleaning or component replacement. The roller screw drive ensures stable operation and minimizes wear, while the filter screen isolates down feathers from the nozzle, preventing fibers from clogging the flow channel.

[0018] 6. By increasing or decreasing the number of storage boxes in the card slot, the single processing volume can be flexibly adjusted to meet the needs of experimental samples or batch production. The inlet pipe structure supports the introduction of other sterilization media besides steam, such as atomized disinfectant, expanding the application scenarios of the equipment.
