Description

Technical Field

[0001] The utility model relates to the technical field of meat duck processing, in particular to a duck feather wax cake leaching and recovery mechanism. Background Art

[0002] Duck feather wax cakes are difficult-to-treat solid waste generated during the production process of meat duck processing plants. The main components are 30% plucked wax and 70% miscellaneous hair, which are discarded, causing pollution to the ecological environment and a huge waste of resources. Shandong Yinan and its vicinity are intensive meat duck processing areas, and waste cakes are difficult to handle. The plucked wax proposed in this process can be reused, and the miscellaneous hair has high added value. The wax is extracted from the waste hair cakes using specific equipment. This process has a high degree of mechanization, low labor intensity, good product quality, and high economic benefits. In the existing duck feather wax cake processing process, leaching equipment is often used to crush the duck feather wax cakes and extract the wax. Existing leaching equipment usually relies on high-speed rotary cutting and stirring of dissolving solvents. However, this method has many defects, which affect the efficient processing of duck feather wax cakes.

[0003] While high-speed rotary cutting can initially break up large duck feather wax cakes, its effectiveness is limited. This is especially true during the subsequent processing of the duck feather and wax mixture, where uniform crushing often fails, resulting in fragments of varying sizes. This uneven crushing not only affects subsequent wax extraction efficiency but also increases energy consumption, preventing efficient wax recovery.

[0004] During the leaching process, existing equipment is ineffective at crushing duck feather fibers due to their length and toughness. In particular, the fine feather fragments are difficult to separate effectively from the dissolved wax. Even when the wax is extracted through stirring and solvents, the fineness of the feather fragments easily causes them to mix with the wax, resulting in impurities in the final product, reducing the purity and quality of the wax and further complicating subsequent impurity removal.

[0005] Existing extraction equipment has a low degree of automation and typically relies on manual operations for crushing, dissolving, and separating materials. This is labor-intensive and complex, prone to human error, and affects the consistency and accuracy of the process. Furthermore, the solvent mixing and crushing equipment operate inefficiently, making it impossible to efficiently complete material crushing and leaching in a short period of time. This results in low production efficiency and is unable to meet the needs of large-scale duck feather wax cake processing.

[0006] In view of this, research and improvement are carried out on the existing problems, and a duck feather wax cake leaching and recovery mechanism is provided to solve the current problems. The purpose is to achieve the purpose of solving the problems and improving the practical value through this technology. Summary of the Invention

[0039] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0040] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0041] The following describes a duck feather wax cake leaching and recovery mechanism provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0042] Combine Figures 1-8 As shown, the present invention provides a duck feather wax cake leaching and recovery mechanism, comprising an immersion barrel 100, a drive box 200, a sifter 300, and a decomposition and leaching mechanism 400. The immersion barrel 100 is internally provided with a heating component for heating and dissolving the duck feather wax cake. By heat-melting and dissolving the duck feather wax cake by the heating component, the wax therein can be effectively extracted, reducing wax waste and improving resource utilization.

[0043] The drive box 200 is fixedly mounted on the top surface of the immersion barrel 100. A main motor 210 is mounted on one side of the drive box 200 to drive the decomposition and leaching mechanism 400. A feed port 201 is defined on the surface of the drive box 200 for feeding materials. The sifter 300 is fixedly mounted on the bottom surface of the immersion barrel 100 and is used to separate the solvent from the duck feather impurities. The separated waxy solution can be discharged from the bottom of the device.

[0044] The decomposition and leaching mechanism 400 includes a main shaft 410, a moving sleeve 420, shear teeth 430, and an eccentric sleeve 440. Multiple main shafts 410 are evenly distributed along the circumference, and the outer surface of each main shaft 410 is connected to the inner side of the immersion barrel 100 via a bearing ring 411 and is rotatably sleeved. The eccentric sleeve 440 is fixedly mounted on the outer surface of the main shaft 410, and the moving sleeve 420 is sleeved on the outer periphery of the eccentric sleeve 440 and is rotatable. A transmission gear sleeve 412 is fixedly mounted on the top of each main shaft 410, and is meshed with the adjacent main shaft 410 through the transmission pin teeth 413, thereby achieving synchronous rotation of the multiple main shafts 410.

[0045] During operation, the output end of the main motor 210 is connected to one of the transmission gear sleeves 412, driving the main shaft 410 and shearing teeth 430 to rotate synchronously. Each of the movement sleeves 420 and shearing teeth 430 reciprocates in the axial and radial directions, shearing and crushing the duck feather wax cakes, improving crushing efficiency and facilitating subsequent wax extraction.

[0046] The movable sleeve 420 is provided with a dynamic wedge 421 at both ends. The surface of the dynamic wedge 421 is an inclined surface. The inclined surface cooperates with the fixed wedge sleeve 441, allowing the movable sleeve 420 to move up and down when rotating, thereby driving the shearing teeth 430 to reciprocate in the axial direction of the dipping barrel 100. Through the coordination of up and down movement and radial movement, the duck feather wax cake can be fully crushed.

[0047] Furthermore, the outer center of the eccentric sleeve 440 is offset from the center of the main shaft 410, allowing the movable sleeve 420 to reciprocate in the radial direction of the immersion barrel 100 as the eccentric sleeve 440 rotates, further driving the shearing and crushing action of the shearing teeth 430 in the radial direction. Adjacent shearing teeth 430 are provided with a plurality of shear blades, which are arranged in a staggered manner to further enhance the crushing effect.

[0048] The sifter 300 rotates the rotary valve plate 320, driven by a reduction motor 340. This releases material through relative rotation with the crushing teeth 330. The rotary valve plate 320 slides against the underside of the reduction motor 340, ensuring smooth material discharge. Diverter sleeves 310 are located on both sides of the device to facilitate material discharge. The crushing teeth 330 are staggered along the radial direction of the immersion drum 100, further shredding the material through mutual shearing. Example

[0049] In this embodiment, the duck feather wax cake leaching and recovery device of the present invention further optimizes the separation and dissolution processes to improve the overall efficiency.

[0050] In this embodiment, multiple temperature sensors are installed on the inner wall of the dipping barrel 100 to monitor the operating status of the heating component and automatically adjust the heating intensity based on temperature feedback. The heating component can adjust the temperature according to the properties of the duck feather wax cake through an intelligent temperature control system, ensuring that the wax is fully dissolved and avoiding energy waste caused by excessive heating.

[0051] The decomposition and leaching mechanism 400 also includes a plurality of main shafts 410. However, in this embodiment, the number of main shafts 410 is increased to ensure that large quantities of duck feather wax cakes can be processed in a shorter time. The top surface of each main shaft 410 is still connected to the drive structure through a transmission gear sleeve 412, and the adjacent transmission pins 413 are meshed.

[0052] In this embodiment, the eccentric sleeve 440 adopts a more precise eccentric design compared to Example 1, further increasing the radial movement range of the moving sleeve 420, thereby enhancing the shearing range of the shearing teeth 430 of the shearing blade. Through this optimized design, the duck feather wax cake is not only fully broken in the axial direction when being sheared, but also achieves a more thorough cutting effect in the radial direction, effectively improving the leaching rate of the wax.

[0053] During the separation phase, the bottom surface of the screener 300 is also equipped with a reduction motor 340, which drives the rotary valve plate 320 to rotate. However, in this embodiment, the rotary valve plate design is more refined to accommodate the separation requirements of different material types. The staggered arrangement of the bottom surface of the rotary valve plate 320 and the crushing teeth 330 is further optimized, ensuring smoother material release and further improving the separation efficiency of impurities and wax.

[0054] The automated control part of the device is also equipped with a real-time monitoring system, which can dynamically adjust various parameters, such as adjusting the speed of the main motor 210, controlling the operating frequency of the reduction motor 340, etc., so as to adapt to different duck feather wax cake processing requirements.

[0055] The working principle and use process of this utility model:

[0056] Working principle:

[0057] Heating and dissolving:

[0058] The main body of the device is a dipping barrel 100, which is provided with a heating component inside. The duck feather wax cake is heated and melted after adding a solvent to start the dissolution process. The heating component provides heat to dissolve the wax in the duck feather wax cake, which is convenient for subsequent leaching.

[0059] Transmission drive and shear crushing:

[0060] The drive box 200 is fixedly mounted on the immersion barrel 100 and has a built-in main motor 210. The motor drives the decomposition and leaching mechanism 400 located in the immersion barrel to rotate. The output end of the drive box is connected to the upper gear assembly of the decomposition and leaching mechanism. By driving the gear transmission sleeve 412 on a main shaft 410, multiple gears are driven to rotate synchronously, so that several main shafts rotate synchronously.

[0061] The decomposition and leaching mechanism includes a plurality of moving sleeves 420 sleeved on an eccentric shaft sleeve 440. The moving sleeve realizes radial and axial reciprocating motion through meshing gear transmission and relative sliding. The upper and lower ends of the moving sleeve are provided with inclined plane components, dynamic inclined wedges 421. Through these inclined planes and the interaction with the fixed wedge sleeve 441 fixed on the inner cavity, the moving sleeve can move up and down when rotating, thereby driving the shearing teeth 430 of the shearing knife to perform reciprocating motion in the axial direction, completing the shearing and crushing of the duck feather wax cake.

[0062] Material separation and discharge:

[0063] A sifter 300 is installed at the bottom of the device to separate the dissolved wax from the duck feather impurities. A reduction motor 340 drives a rotary valve plate 320 to rotate the sifter. During rotation, the material shears against the crushing teeth 330, further crushing and filtering it, ensuring effective separation of the wax from impurities. The separated wax is discharged from a discharge port 311 and enters subsequent processing steps.

[0064] Usage process:

[0065] Material preparation and feeding: First, the duck feather wax cake that has been pre-treated, such as crushed, is put into the feeding port 201 of the dipping barrel. The heating component of the dipping barrel starts working, and after heating the duck feather wax cake for a period of time, the wax inside it is gradually melted.

[0066] Start the drive system, and drive the main shaft 410 of the decomposition and leaching mechanism to rotate synchronously through the main motor 210. The main shaft drives the moving sleeve 420 and the shearing teeth 430 of the shearing knife to reciprocate in the axial and radial directions, and further shear and crush the duck feather wax cakes; the design of the shearing knife makes adjacent blades staggered with each other, which effectively improves the shearing efficiency and ensures that the material is fully crushed and dissolved.

[0067] The crushed duck feather wax cake is filtered and separated through the sifter 300 at the bottom. The rotary valve plate 320 is driven by the reduction motor to rotate, and the sheared and crushed materials are mixed with the solvent. The wax is discharged through the filter holes of the sifter, and the impurities are trapped inside the sifter. Through continuous rotation and shearing, the material is ensured to be fully processed.

[0068] The separated wax is discharged through the discharge port 311 and enters the subsequent purification and treatment process, while the remaining impurities are discharged through the discharge port on the side of the screener for further waste treatment or reuse.
