Description

Technical Field

[0001] The invention relates to the technical field of meat duck processing, in particular to a duck feather wax cake leaching and recovery device and a process thereof. Background Art

[0002] Duck feather wax cake is a kind of difficult-to-treat solid waste generated in the production process of meat duck processing plants. Its main components are 30% plucked wax and 70% miscellaneous hair, which pollutes the ecological environment and causes 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 reuse the miscellaneous hair and has high added value. It is to use specific equipment to extract wax from waste hair cake. 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 duck feather wax cakes and extract 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] Although high-speed rotary cutting can be used to initially crush large pieces of duck feather wax cakes, its crushing effect is limited, especially in the subsequent processing of the duck feather and wax mixture, it is often impossible to achieve a uniform degree of crushing, resulting in the presence of fragments of different sizes in the material. This uneven crushing not only affects the subsequent wax leaching efficiency, but also leads to an increase in energy consumption, and it is impossible to achieve efficient wax recovery.

[0004] During the leaching process, due to the long and tough duck feather fibers, the existing equipment is not effective in crushing them, especially during the crushing process, the fine fragments of duck feathers are difficult to effectively separate from the dissolved wax. Even if the wax is leached through stirring and solvent, due to the fineness of the duck feather fragments, these fragments are easily mixed with the wax, resulting in impurities in the final product, reducing the purity and quality of the wax, and further increasing the difficulty of subsequent impurity treatment.

[0005] The existing leaching equipment has a low degree of automation and usually relies on manual operation for crushing, dissolving and material separation. It is labor-intensive and complicated to operate, prone to human errors, and affects the consistency and accuracy of the treatment. At the same time, the operating efficiency of the solvent stirring and crushing equipment is low, and it is impossible to efficiently complete the crushing and leaching of materials in a short time. The production efficiency is relatively low and cannot 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 device and its process are 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

[0026] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0027] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention. Embodiment 1:

[0028] A duck feather wax cake leaching and recovery device and process thereof provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0029] Combination Figure 1-Figure 8 As shown, a duck feather wax cake leaching and recovery device provided by the present invention includes an immersion barrel 100, a drive box 200, a sifter 300 and a decomposition leaching mechanism 400. A heating component is provided inside the immersion barrel 100 for heating the duck feather wax cake to dissolve it. The heating component is used to heat and dissolve the duck feather wax cake, so that the wax therein can be effectively extracted, reducing wax waste and improving resource utilization.

[0030] The driving box 200 is fixedly mounted on the top surface of the immersion barrel 100, and a main motor 210 is installed on one side of the driving box 200 to drive the decomposition and leaching mechanism 400 to rotate. A feeding port 201 is provided on the surface of the driving box 200, which is the material feeding port. The sifter 300 is fixedly mounted on the bottom surface of the immersion barrel 100, and is used to separate the solvent and the duck feather impurities. The separated wax solution can be discharged from the bottom of the device.

[0031] The decomposition and leaching mechanism 400 includes a main shaft rod 410, a moving sleeve 420, a shearing tooth 430 and an eccentric sleeve 440. A plurality of main shaft rods 410 are evenly distributed along the circumferential direction, and the outer surface of each main shaft rod 410 is connected to the inner side of the immersion barrel 100 through a bearing ring 411 and is rotatably sleeved. The eccentric sleeve 440 is fixedly mounted on the outer surface of the main shaft rod 410, and the moving sleeve 420 is sleeved on the outer periphery of the eccentric sleeve 440 and can rotate. A transmission gear sleeve 412 is fixedly mounted on the top of each main shaft rod 410, and is meshed and transmitted with the adjacent main shaft rod 410 through a transmission pin 413, thereby realizing the synchronous rotation of multiple main shaft rods 410.

[0032] When the device is in 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 the shearing teeth 430 to rotate synchronously. Each movement sleeve 420 and the shearing teeth 430 reciprocate in the axial and radial directions to shear and crush the duck feather wax cake, thereby improving the crushing efficiency and facilitating the subsequent leaching of the wax.

[0033] The moving sleeve 420 is provided with a moving wedge 421 at both ends, and the surface of the moving wedge 421 is an inclined surface, which cooperates with the fixed wedge sleeve 441, so that the moving sleeve 420 can move up and down when rotating, thereby driving the shearing teeth 430 to reciprocate in the axial direction of the immersion barrel 100. Through the cooperation of up and down movement and radial movement, the duck feather wax cake can be fully crushed.

[0034] In addition, the outer circumference center of the eccentric sleeve 440 deviates from the center of the main shaft 410, so that the moving sleeve 420 can reciprocate in the radial direction of the immersion barrel 100 when the eccentric sleeve 440 rotates, further driving the shearing and crushing action of the shearing teeth 430 in the radial direction. A plurality of shearing blades are provided on the surface of adjacent shearing teeth 430, and the shearing blades are arranged in a staggered manner, further enhancing the crushing effect.

[0035] The sifter 300 drives the rotary valve plate 320 to rotate through the reduction motor 340, and releases the material through relative rotation with the crushing teeth 330. The rotary valve plate 320 slides against the bottom surface of the reduction motor 340 to ensure that the material can be discharged smoothly. Diverter sleeves 310 are provided on both sides of the device for material output, and the crushing teeth 330 are staggered along the radial direction of the immersion barrel 100 to further shred the material through mutual shearing. Embodiment two:

[0036] In this embodiment, the duck feather wax cake leaching and recovery device of the present invention further optimizes the separation and dissolution process to improve the overall efficiency.

[0037] In this embodiment, a plurality of temperature sensors are installed on the inner wall of the immersion barrel 100 to monitor the working state of the heating component and automatically adjust the heating intensity according to the temperature feedback. The heating component can adjust the temperature according to the properties of the duck feather wax cake through the intelligent temperature control system to ensure that the wax is fully dissolved and avoid energy waste caused by excessive heating.

[0038] The decomposition and leaching mechanism 400 is also designed to include a plurality of main shafts 410, but in this embodiment, the number of main shafts 410 is increased to ensure that a large number 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 driving structure through a transmission gear sleeve 412, and is adjacently meshed through a transmission pin 413.

[0039] In this embodiment, the eccentric sleeve 440 adopts a more precise eccentric design compared to the embodiment 1, further improving the radial movement range of the moving sleeve 420, thereby enhancing the shearing range of the shearing teeth 430 of the shearing blade. Through such an optimized design, when the duck feather wax cake is cut into pieces, it is not only fully broken in the axial direction, but also can obtain a more thorough cutting effect in the radial direction, effectively improving the leaching rate of the wax.

[0040] In the separation stage, the bottom surface of the sifter 300 is also provided with a reduction motor 340 for driving the rotary valve plate 320 to rotate, but in this embodiment, the design of the rotary valve plate is more refined to meet the separation requirements of different types of materials. The staggered arrangement of the bottom surface of the rotary valve plate 320 and the crushing teeth 330 is further optimized, so that the release of the material is smoother and the separation efficiency of impurities and wax is further improved.

[0041] 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.

[0042] A duck feather wax cake leaching and recovery process comprises the following steps: Figure 8 As shown: S1: Pretreatment: crushing the waste wax cake to prepare for subsequent leaching; S2: Leaching: The pretreated material is sent to the leacher 2 through the scraper elevator 1 to fully contact with the solvent (n-ethane) and then the wax is transferred to the solvent through molecular exchange movement to form a mixed oil; S3: Mixed oil separation: The mixed oil enters the mixed oil tank 3, and then is separated by the hydrocyclone 7 and the evaporator 5; during the separation process, the wax is separated from the solvent, the wax is collected in the tank, and the solvent enters the recovery stage; S4: Solvent recovery: The separated solvent is evaporated and condensed through the dry steam drum 6 and the box condenser, and then the solvent is recovered through the solvent turnover box 12 and the solvent pump 13 to form a cycle and reduce solvent consumption; S5: Miscellaneous hair treatment: The wool after leaching still contains a small amount of solvent, which is further extracted by heating and negative pressure, and the tail gas is collected and filtered through the tail gas recovery tower 10; the wool after leaching still contains a small amount of solvent, and the residual solvent in the wool is further extracted by heating and negative pressure treatment, and the residue impurities are removed by the residue collector 4 S6: Wax treatment: The wax obtained from the leaching process may contain impurities. Through further decolorization and degumming processes, it can meet industrial use standards and improve product quality.

[0043] The working principle and use process of the present invention: Working principle: Heating and dissolving: The main body of the device is a dipping barrel 100, the inner side of which is provided with a heating component, and the duck feather wax cake is heated and melted after adding a solvent, and the dissolution process begins. The heating component provides heat to dissolve the wax in the duck feather wax cake, which is convenient for subsequent leaching.

[0044] Transmission drive and shearing crushing: The driving 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 driving box is connected to the upper gear assembly of the decomposition and leaching mechanism, and drives a gear transmission sleeve 412 on a main shaft rod 410 to drive multiple gears to work in conjunction, so that several main shaft rods rotate synchronously.

[0045] The decomposition and leaching mechanism includes a plurality of moving sleeves 420 sleeved on an eccentric shaft sleeve 440. The moving sleeves realize radial and axial reciprocating motion through meshing gear transmission and relative sliding. The upper and lower ends of the moving sleeves are provided with inclined plane assemblies and moving inclined wedges 421. Through the interaction of these inclined planes with the fixed wedge sleeves 441 fixed on the inner cavity, the moving sleeves can move up and down when rotating, thereby driving the shearing teeth 430 of the shearing knife to reciprocate in the axial direction, thereby completing the shearing and crushing of the duck feather wax cakes.

[0046] Material separation and discharge: A sifter 300 is installed at the bottom of the device to separate the dissolved wax and duck feather impurities. The sifter drives the rotary valve plate 320 to rotate through the reduction motor 340. During the rotation, the material is further crushed and filtered through mutual shearing with the crushing teeth 330 to ensure effective separation of wax and impurities; the separated wax is discharged from the discharge port 311 and enters the subsequent processing process.

[0047] Usage process: 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, and the heating component of the dipping barrel starts to work. After heating the duck feather wax cake for a period of time, the wax inside it is gradually melted.

[0048] Start the driving 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, so as to 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.

[0049] The broken duck feather wax cake is filtered and separated through the sifter 300 at the bottom. The rotary valve plate 320 is driven to rotate by the reduction motor to shear the broken material and mix it 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.

[0050] 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.
