Description

Technical Field

[0001] This utility model relates to the field of down fiber deodorization treatment technology, specifically a down fiber deodorization treatment device. Background Technology

[0002] In the processing of down fibers, washing and deodorization are key steps that directly affect the cleanliness and performance of the finished down product. Down fiber deodorization equipment is used to remove odors from down fibers. Currently, agitation-type deodorization equipment is commonly used. This equipment typically consists of a processing tank, a mixing mechanism, and a deodorant addition system. The processing tank holds the down for deodorization; the mixing mechanism generally includes a motor, a drive shaft, and a mixing shaft, with the motor driving the drive shaft to rotate the mixing shaft; and the deodorant addition system evenly distributes the deodorant into the processing tank.

[0003] Existing stirring deodorization equipment, such as the cleaning and deodorization structure for down processing proposed in technical document CN221480167U, introduces a reciprocating and centering mechanism into the down processing equipment. The up-and-down movement of the main stirring shaft ensures that the deodorant is evenly dispersed and the feathers are fully soaked, solving the problems of uneven integration of deodorant and feather floating in the existing technology, thus improving deodorization efficiency and safety.

[0004] However, down fibers tend to adhere to the inner wall of the cavity after being stirred or impacted by water flow in the cleaning solution, making them difficult to detach automatically. Technical document CN221480167U does not consider the adhesion defect on the inner wall and cannot fundamentally solve the fiber retention problem. The technical document relies on the main stirring shaft to drive the stirring blades to rotate, but the stirring blades only act on the central area of ​​the cylinder. When down fibers adhere to the inner wall of the stirring cylinder due to centrifugal force or adhesion, the up-and-down movement of the reciprocating mechanism (achieved through the cooperation of the first radial support arm and the wave-shaped second roller groove) and the push plate movement of the centering mechanism (through the transverse separation of down by the second push plate) cannot reach the cylinder wall area. This results in the down adhering to the inner wall not being able to contact the cleaning solution and deodorizer, forming a cleaning dead zone and reducing the uniformity of deodorization. As the cleaning process continues, these adhered down fibers gradually accumulate, forming a thick residual layer, which affects the deodorization effect of the equipment on the down fibers on the inner wall surface of the treatment box. Therefore, a down fiber deodorization treatment device is provided. Utility Model Content

[0005] The purpose of this invention is to provide a down fiber deodorization treatment device to solve the problem in the above-mentioned background technology that the attached down gradually accumulates, forming a thick residual layer, which affects the deodorization effect of the device on the down fiber on the inner wall surface of the treatment box.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a down fiber deodorization treatment device, comprising a device housing, a drive base fixed to the bottom of the device housing, and a motor installed in the drive base. The output end of the motor is connected to a main stirring shaft that passes through the bottom of the device housing. The side wall of the device housing is respectively provided with a down feeding port and a fiber discharge valve. The main stirring shaft drives a scraping component to rotate through a connecting assembly. The scraping component includes a scraper arm that movably abuts against the inner wall of the device housing. A roller groove is opened on the contact side of the scraper arm. Several elastic pressure rollers are installed in the roller groove through a pressure roller shaft. When the elastic pressure rollers contact the inner wall of the device housing, they undergo adaptive deformation according to the change in the thickness of the inner wall adhesion layer.

[0007] This utility model has at least the following beneficial effects:

[0008] 1. When used in this application, the problem of down fibers adhering to the inner wall during the cleaning process can be effectively addressed. By setting a scraper arm structure linked to the main stirring shaft, the scraper arm moves along the inner wall while stirring the down fibers and cleaning liquid, automatically removing the adhering down and impurities. This avoids the down fibers adhering to the inner wall of the device housing not being fully mixed with the deodorizer. The scraper arm structure does not require additional power and is driven by the main shaft of the stirring system. It has a compact structure and stable operation, which not only improves the cleaning efficiency but also reduces the frequency of manual cleaning and lowers maintenance costs. At the same time, the continuous cleaning action of the scraper arm helps the cleaning liquid and deodorizing liquid to be evenly distributed inside the device, enhancing the cleaning effect and improving the deodorization quality.

[0009] 2. When the inner wall forms an uneven layer of down fibers due to aggregation (resulting in a local reduction in inner diameter), the elastic pressure roller can fill the gap between the attached down fibers and the scraper arm through instant elastic deformation. Furthermore, the deformation of the elastic pressure roller can keep the attached down fibers loose through flexible compression, which, combined with the scraper arm blade, makes it easier to peel them off, ensuring continuous removal of the attached fibers.

[0016] 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.

[0017] Please see Figures 1 to 2 This utility model provides a technical solution: a down fiber deodorization treatment device, including a device housing 1. The device housing 1 is used to contain down fibers to be treated and a cleaning and deodorizing liquid. A drive base 2 is fixedly installed at the bottom of the device housing 1. A motor 3 is installed inside the drive base 2. A main stirring shaft 301 is fixedly connected to the output end of the motor 3. In use, the motor 3 drives the main stirring shaft 301 to rotate on the inner wall of the device housing 1 to realize the stirring, cleaning and deodorizing operation of the down fibers. A down feeding port 4 is fixedly installed on one side of the device housing 1. One end of the down feeding port 4 penetrates the device housing 1 and communicates with its interior, so as to facilitate the feeding of down fibers into the interior for cleaning treatment. A fiber discharge valve 5 is fixedly connected to the other side of the device housing 1. One end of the fiber discharge valve 5 also penetrates the device housing 1 and communicates with its interior, so as to discharge the down fibers that have completed the cleaning and deodorizing treatment.

[0018] Please see Figures 3 to 5 As an embodiment of this utility model, in order to solve the problem that down fibers easily adhere to the inner wall of the device housing 1 during the washing and deodorizing process, the following design is proposed based on the main stirring shaft 301 being rotatably mounted at the bottom of the device housing 1 via a bearing:

[0019] The main stirring shaft 301 is designed to pass through the bottom of the device housing 1 and extend to the bottom of the housing to facilitate connection to the external power unit motor 3. A linkage sleeve 302 is fixedly fitted onto the outside of the main stirring shaft 301. Several scraper arm connecting rods 303 are evenly distributed and fixedly connected around the linkage sleeve 302. A scraper arm 304 is fixedly connected to the top of each scraper arm connecting rod 303 on the side away from the main stirring shaft 301. The cross-section of the scraper arm 304 is designed to be triangular; in specific implementation, the side of the scraper arm closest to the inner wall of the device housing is designed to be concave. The curved surface has a radius of curvature that matches the inner wall radius of the device housing 1. The two sides of the scraper arm 304 have a double-blade-like structure with a blade inclination angle of 20°-35° and a thin edge thickness of 0.5-2mm. It can be understood that the concave curved surface and the blade-like edge are smoothly connected to form a continuous scraping surface. The concave curved surface adapts to the inner wall of the tank to avoid scraping dead corners, so that the thinner edge is more conducive to the scraper arm 304 scraping the down attached to the inner wall. The scraper arm 304 is made of stainless steel in one piece by stamping.

[0020] Its operating principle is as follows: When the motor 3 drives the main stirring shaft 301 to rotate, the linkage sleeve 302 drives the scraper arm connecting rod 303 and the scraper arm 304 to rotate together, causing the scraper arm 304 to move in a circular motion along the inner wall of the device housing 1. This effectively removes down fibers and impurities adhering to the inner wall of the device housing 1, thus preventing down fibers from adhering to the inner wall of the device housing 1 for a long time, causing blockage, contamination, or affecting the subsequent cleaning effect. This not only improves cleaning efficiency but also reduces the frequency of manual cleaning and lowers maintenance costs. It is understood that this scraper arm structure does not require additional power, relying on the main shaft of the stirring system for drive. It has a compact structure, stable operation, and allows the cleaning liquid to be more evenly distributed inside the device housing 1, enhancing the contact effect between the cleaning liquid and the down fibers, thereby improving the overall cleaning and deodorization efficiency.

[0021] Based on the above technical concept, a roller groove 308 is provided on the side of the scraper arm 304 away from the scraper arm connecting rod 303. A pressure roller shaft 309 is provided inside the roller groove 308. The two ends of the pressure roller shaft 309 are rotatably mounted on the upper and lower ends inside the roller groove 308 via bearings. Several elastic pressure rollers 310 are fixedly mounted on the outside of the pressure roller shaft 309. One end of each elastic pressure roller 310 is in movable contact with the inner wall of the device housing 1, used to remove down fibers or impurities adhering to the inner wall of the device housing 1 during the rotation of the main stirring shaft 301. When the inner wall forms uneven thickness due to the accumulation of down fibers... During the deposition (resulting in a localized reduction in inner diameter), the elastic pressure roller 310 can fill the gap between the attached down fibers and the scraper arm through instant elastic deformation. Furthermore, the deformation of the elastic pressure roller 310 can keep the attached down fibers loose through flexible compression, making it easier to peel them off in conjunction with the blade edge of the scraper arm 304, ensuring continuous removal of the attached fibers. The device housing 1 is also equipped with a stabilizing seat 305. Four radial support arms 306 are fixedly connected to the periphery of the stabilizing seat 305. The ends of the radial support arms 306 are fixedly connected to the inner wall of the device housing 1, thereby achieving stable support for the stabilizing seat 305.

[0022] Please see Figure 2 As an embodiment of this utility model, to optimize the deodorization process of down fibers, improve cleaning efficiency and deodorization effect, and facilitate wastewater discharge and equipment maintenance, the top end of the main stirring shaft 301 is rotatably connected to the bottom of the stable seat 305 via a bidirectional thrust bearing to form axial and radial dual constraints, ensuring good stability of the main stirring shaft 301 during rotation. Simultaneously, several spiral ribbon-shaped fiber agitators 307 are fixedly connected to the outside of the main stirring shaft 301. These fiber agitators 307 rotate with the main stirring shaft 301 to agitate the down fibers and cleaning liquid, ensuring thorough mixing and improving cleaning efficiency. To improve deodorization efficiency, a wastewater discharge port 6 is provided at the bottom of the device housing 1 for discharging wastewater generated after cleaning. A stainless steel filter screen is embedded in the inner wall of the wastewater discharge port 6, and a liquid control gate 7 is fixedly installed at the bottom via a flange structure to control the drainage process, facilitating cleaning and maintenance by operators. A maintenance window 8 is provided at the top of the device housing 1, penetrating the device housing 1 and communicating with the interior of the device housing 1, facilitating observation of equipment operation or maintenance work. A sealing end cover 9 is fixedly connected to the inside of the maintenance window 8 via bolts. The sealing end cover 9 is removable, facilitating cleaning or replacement of parts inside the device housing 1.

[0023] As an explanation of the principle of this utility model:

[0024] When using the device, first confirm that all components are installed in place and in normal working condition. First, the operator should check through the inspection window 8 whether the inside of the device housing 1 is clean and free of residue. If cleaning is required, the sealing end cover 9 can be removed first, and the inside of the device housing 1 can be wiped or rinsed before restoring it to its original state. Then, the down fibers to be treated are fed into the inside of the device housing 1 through the down feeding port 4, ensuring that the material is evenly distributed inside the device housing 1 to avoid accumulation that affects the cleaning effect. Next, an appropriate amount of cleaning liquid or deodorizer is injected into the inside of the device housing 1 through the external liquid adding device. The liquid level should be reasonably controlled according to the type of down fiber and the degree of contamination to ensure the cleaning and deodorizing effect.

[0025] After starting the motor 3, the motor 3 drives the main stirring shaft 301 to rotate. The main stirring shaft 301 drives the linkage sleeve 302 to rotate, which in turn causes the scraper arm 304, which is fixedly connected to the top of the scraper arm connecting rod 303, to move along the inner wall of the device housing 1 to remove any down fibers or impurities that may adhere to it. At the same time, the fiber stirring fins 307, which are fixed to the outside of the main stirring shaft 301, rotate together with the main stirring shaft 301, stirring the down fibers and mixing them thoroughly with the cleaning liquid to improve the cleaning and deodorizing efficiency. During the stirring process, the stabilizing seat 305 is fixedly connected to the inner wall of the device housing 1 through four radial support arms 306, providing top support for the main stirring shaft 301 to ensure its smooth operation and reduce vibration and noise. It should be noted that the radial support arms 306 have a streamlined wing-shaped cross-section. The wing-shaped cross-section reduces hydraulic resistance and prevents down fibers from getting caught. The front end of the wing is welded to the stabilizing seat 305, and the end is bolted to the inner wall of the device housing 1 through a flange structure.

[0026] After cleaning and deodorization are completed, turn off motor 3, open the hydraulic control gate 7 located at the bottom of waste liquid discharge port 6 to discharge the wastewater inside the device housing 1. After the wastewater is discharged, close the hydraulic control gate 7. Then, the operator opens the fiber discharge valve 5 to discharge the down fibers that have been cleaned and deodorized from the device for subsequent drying or sorting processes. During daily use, the inside of the device housing 1 can be observed regularly through the inspection window 8. If any accumulated material or dirt is found, the sealing end cover 9 can be removed for manual cleaning to ensure long-term stable operation of the equipment.

[0027] It should be noted that the proposed down fiber deodorization treatment device takes into account the problem that down fibers easily adhere to the inner wall of the equipment during the cleaning and deodorization process in its structural design. By setting up components such as scraper arms 304, the inner wall of the device housing 1 can be cleaned. A linkage sleeve 302 is fixedly installed on the outside of the main stirring shaft 301. The outside of the linkage sleeve 302 is connected to the scraper arms 304 through several scraper arm connecting rods 303. One side of the scraper arm 304 is in contact with the inner wall of the device housing 1. When the main stirring shaft 301 is rotated under the drive of the external power device, the scraper arm 304 moves in a circle along the inner wall of the device housing 1. This can effectively remove down fibers and impurities adhering to the inner wall of the device housing 1, avoiding the situation where down fibers adhere to the inner wall of the device housing 1 for a long time, causing blockage, pollution or affecting the subsequent cleaning effect. This achieves the effect of improving cleaning efficiency, reducing the frequency of manual cleaning, and reducing maintenance costs.

[0028] Furthermore, the scraper arm 304 operates synchronously with the stirring process, requiring no additional power source. Its compact structure ensures the continuity and stability of the device's operation. In addition, the presence of the scraper arm 304 allows the cleaning liquid to be distributed more evenly inside the device housing 1, enhancing the contact effect between the cleaning liquid and the down fibers, thereby improving the overall cleaning and deodorizing efficiency. In summary, this utility model effectively solves the problem of down fibers easily adhering to the inner wall of the device housing 1 during the cleaning and deodorizing process by setting up a scraper arm 304 structure that is linked with the main stirring shaft 301. It has the advantages of thorough cleaning, convenient operation, and easy maintenance.
