Description

Technical Field

[0001] This invention relates to a device for opening, removing impurities, and recycling waste textiles, belonging to the field of textile fiber processing technology. Background Technology

[0002] With the rapid development of the textile industry and the upgrading of consumption, tens of millions of tons of waste textiles are generated globally every year. Their recycling and reuse have become an important way to alleviate resource shortages and reduce environmental pollution. Opening and removing impurities is the core process of waste textile recycling, which directly determines the quality of recycled fibers and subsequent processing performance. Currently, the industry generally adopts forced separation opening and impurity removal technology, which mainly uses the high-speed impact, tearing, and combing action of mechanical components such as licker-in rollers, rollers, and beaters to separate tangled fibers and remove impurities. However, this type of technology has an irreconcilable fundamental contradiction: to improve opening efficiency and impurity removal effect, the mechanical external force needs to be increased, which will lead to a large number of fiber breaks, shortening of length, and reduction of strength, seriously reducing the use value of recycled fibers and making it difficult to use them in the production of high value-added textiles. If the external force is reduced to protect the fibers, problems such as insufficient opening, more tangled fiber clumps remaining, and low impurity removal rate will occur, affecting the quality of subsequent processing. In addition, most existing technologies separate opening and impurity removal into two independent processes, which are long process flows, large equipment footprints, and high energy consumption. Moreover, impurities are easily further broken during the opening process, increasing the difficulty of subsequent impurity removal. To solve the above-mentioned technical problems, a waste textile opening, impurity removal and recycling device is proposed. Summary of the Invention

The elastic support unit includes a base frame and four air springs equidistantly distributed on the top of the base frame. The top of the air springs is fixedly connected to the bottom of the vertical resonant cavity. The top of the vertical resonant cavity is connected to a sleeve.

[0006] More preferably, the lower end of the spiral guide is integrally formed with an extension, which penetrates the bottom of the vertical resonant cavity and communicates with the air inlet of the suction fan. The bottom of the extension is provided with a discharge hole, and an arc-shaped filter plate is fixedly connected inside the extension. The arc-shaped filter plate has filter holes evenly distributed.

[0007] More preferably, the air inlet of the suction fan is equipped with a conical guide cover, which is coaxially arranged with the extension of the spiral guide component, and the large-diameter end of the conical guide cover faces the interior of the vertical resonant cavity.

[0008] More preferably, the shredding mechanism includes a feed hopper, a discharge hopper, and a pair of meshing rotary cutters; The roller cutters are symmetrically rotated and installed inside the frame. A drive motor is installed on the top of the frame. The output shaft of the drive motor is connected to the drive shaft of one of the roller cutters through a coupling.

[0009] More preferably, the bottom of the discharge hopper is connected to a discharge pipe, and the lower end of the discharge pipe is inserted into the inside of the sleeve.

[0010] More preferably, the X-axis exciter and the Y-axis exciter are both installed at the middle height of the outer wall of the vertical resonant cavity, corresponding to the center position of the main resonant section of the spiral guide.

[0011] More preferably, the inner diameter of the sleeve is 2-4 mm larger than the outer diameter of the discharge pipe.

[0012] More preferably, the control cabinet is electrically connected to the Z-axis vibrator, X-axis vibrator, Y-axis vibrator, suction fan, and drive motor respectively; the control cabinet can independently adjust the frequency and amplitude of each vibrator, the speed of the suction fan, and the speed of the drive motor.

Moreover, the control cabinet can independently adjust the parameters of each vibrator and the fan speed, which can adapt to the processing needs of waste textiles with different materials and different impurity contents, significantly enhancing its versatility and practicality.

[0018] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] like Figure 1-6 As shown, this embodiment of the invention provides a waste textile opening and impurity removal recycling device, which consists of a main body 10, a shredding mechanism 20 and a resonant opening mechanism 30.

[0021] The main structure 10 includes a frame 11 and a control cabinet 12. The chopping mechanism 20 is installed inside the upper part of the frame 11, and the resonant loosening mechanism 30 is located inside the lower part of the frame 11. A suction fan 38 is provided on one side of the resonant loosening mechanism 30, and the suction fan 38 is fixedly installed on the side wall of the frame 11. The frame 11 provides a stable installation foundation and structural support for the entire device, integrating the chopping mechanism 20 and the resonant loosening mechanism 30 into the same frame to ensure the coaxiality and operational stability of each component. The control cabinet 12 serves as the control center of the device, realizing centralized control and parameter adjustment of all power components, and ensuring the coordinated operation of each process of the device.

[0022] The shredding mechanism 20 includes a feed hopper 21, a discharge hopper 22, and a pair of meshing rotary cutters 24. The rotary cutters 24 are symmetrically rotatably mounted inside the frame 11. A drive motor 25 is mounted on the top of the frame 11. The output shaft of the drive motor 25 is connected to the drive shaft of one of the rotary cutters 24 via a coupling. The two rotary cutters 24 rotate synchronously in opposite directions via gear transmission. The feed hopper 21 is mounted on the top of the frame 11 and above the rotary cutters 24. The discharge hopper 22 is mounted inside the frame 11 and below the rotary cutters 24. The bottom of the discharge hopper 22 is connected to a discharge pipe 23. The lower end of the discharge pipe 23 is inserted into the inside of a sleeve 32. The inner diameter of the sleeve 32 is larger than the outer diameter of the discharge pipe 23, forming an annular air intake between the sleeve 32 and the discharge pipe 23. The feed hopper 21 is used to receive and process waste textiles, guiding the material smoothly into the meshing area of ​​the roller cutter 24; the drive motor 25 provides power to the roller cutter 24, and the gear transmission ensures that the two roller cutters 24 rotate at the same speed and in opposite directions, so as to achieve continuous and uniform shearing of waste textiles; the roller cutter 24 adopts a meshing structure, which can cut waste textiles of different thicknesses and materials into small pieces of the same size, avoiding large pieces of material from affecting the processing effect when entering the subsequent resonant loosening mechanism 30; the discharge hopper 22 collects the shredded material and conveys the material to the resonant loosening mechanism 30 through the discharge pipe 23; the discharge pipe 23 and the sleeve 32 adopt a non-rigid plug connection, which can completely block the vibration of the vertical resonant cavity 31 from being transmitted to the shredding mechanism 20.

[0023] The resonant opening mechanism 30 includes a vertical resonant cavity 31, a spiral guide 35, a three-dimensional excitation unit, and an elastic support unit. The spiral guide 35 is fixedly installed on the inner wall of the vertical resonant cavity 31 and extends spirally along the height of the cavity. The spiral guide 35 has a three-section variable lead structure, consisting of a pre-resonance section, a main resonance section, and a fine opening section from top to bottom. The cross-section of the spiral guide 35 is arc-shaped, with the outer side wall of the spiral guide 35 fitting against the inner wall of the vertical resonant cavity 31 and the inner side wall suspended. The vertical resonant cavity 31 provides a sealed space environment for the resonant separation of materials. Its cylindrical structure enables the vibration waves to be uniformly reflected and propagated within the cavity, ensuring that all materials are subjected to a uniform resonant force. The spiral guide 35 extends spirally along the inner wall. The spiral extension guides the material to fall slowly along the spiral path, significantly extending the effective residence time of the material in the cavity and ensuring thorough opening and impurity removal. Its arc-shaped cross-section reduces hard friction between the material and the guide, minimizing mechanical damage to the fibers. The three-stage variable lead structure enables precise processing in stages. The pre-resonance stage has a larger lead and a faster material falling speed, allowing the material to gradually adapt to the cavity vibration and preventing the fiber from breaking brittlely due to sudden strong resonance force. The main resonance stage has a moderate lead and the material has the longest residence time in this stage, which is the core stage for separating fibers from impurities. The fine opening stage has a smaller lead and the slowest material falling speed, used to finely untangle the remaining small amount of entangled fibers and further improve the uniformity of opening.

[0024] The three-dimensional vibration unit includes a Z-axis vibrator 39 installed at the center of the bottom of the vertical resonant cavity 31, two X-axis vibrators 33 and two Y-axis vibrators 34 symmetrically installed on the outer wall of the vertical resonant cavity 31; the output axes of the X-axis vibrators 33 and Y-axis vibrators 34 are perpendicular to each other and intersect at the central axis of the vertical resonant cavity 31; the X-axis vibrators 33 and Y-axis vibrators 34 are both installed at the center height of the outer wall of the vertical resonant cavity 31, corresponding to the center position of the main resonant section of the spiral guide 35; the Z-axis vibrator 39 generates periodic vibration in the vertical direction, causing the material to jump up and down on the spiral guide 35, promoting the separation of fibers and impurities. Longitudinal separation: Two X-axis vibrators 33 and two Y-axis vibrators 34 are symmetrically arranged to generate horizontal vibrations perpendicular to each other, causing the material to swing left and right and back and forth in the horizontal direction, breaking the entanglement between fibers laterally; the X-axis vibrators 33 and Y-axis vibrators 34 are installed at the center of the main resonance section, which enables the main resonance section to obtain the maximum vibration amplitude and ensures the processing effect of the core separation stage; the vibrators in three directions work together to generate three-dimensional composite resonance in the vertical resonance cavity 31. Compared with vibration in a single direction, it can act on the material from multiple dimensions at the same time, greatly improving the efficiency of fiber untangling and impurity separation; The synergistic resonance control principle of the three-dimensional excitation unit is as follows: The control cabinet 12 independently adjusts the frequency and amplitude of the Z-axis vibrator 39, X-axis vibrator 33, and Y-axis vibrator 34 according to the fiber material and impurity type of the waste textile to be processed, so that the overall resonance frequency of the vertical resonance cavity 31 matches the natural frequency of the impurities and is far away from the natural frequency of the fibers; the impurities generate large-amplitude vibration under the excitation of the resonance frequency and quickly detach from the fibers, while the fibers only gently untangle under the low-amplitude resonance effect, avoiding breakage damage due to resonance overload; the X-axis vibrator 33 and the Y-axis vibrator 34 are symmetrically arranged and their output shafts intersect perpendicularly, which can eliminate the horizontal vibration eccentric force, ensure the stable operation of the vertical resonance cavity 31, and the three-dimensional composite resonance effect covers the entire space of the vertical resonance cavity 31 without vibration dead angles, ensuring that the material receives the resonance effect uniformly and achieving efficient separation of fibers and impurities.

[0025] The elastic support unit includes a base frame 36 and four air springs 37 equidistantly distributed on the top of the base frame 36. The top of the air springs 37 is fixedly connected to the bottom of the vertical resonant cavity 31. The base frame 36 is fixedly installed on the bottom inner wall of the frame 11. The top of the vertical resonant cavity 31 is connected to a sleeve 32. The base frame 36 provides a stable support foundation for the air springs 37 and the vertical resonant cavity 31. The four air springs 37 are equidistantly distributed, which can evenly bear the weight of the vertical resonant cavity 31. At the same time, the elastic properties of air are used to buffer the vibration generated by the cavity, avoid the vibration from being transmitted to the frame 11 and the ground, and reduce the noise and vibration interference during the operation of the device. In addition, the air springs 37 can also change the support stiffness by adjusting the internal air pressure, which helps to optimize the resonance characteristics of the cavity and makes it easier for the cavity to reach the preset resonance state.

[0026] The lower end of the spiral guide 35 is integrally formed with an extension, which penetrates the bottom of the vertical resonant cavity 31 and communicates with the air inlet of the suction fan 38. An exhaust hole 42 is opened at the bottom of the extension, and an arc-shaped filter plate 41 is fixedly connected inside the extension. Filter holes are evenly distributed on the arc-shaped filter plate 41. A conical guide shroud is installed at the air inlet of the suction fan 38. The conical guide shroud is coaxially arranged with the extension of the spiral guide 35, and the large-diameter end of the conical guide shroud faces the interior of the vertical resonant cavity 31. The extension at the lower end of the spiral guide 35 concentrates and guides the loosened material to the air inlet area of ​​the suction fan 38. The arc-shaped filter plate 41... Fixed inside the extension section, its arc-shaped structure can significantly increase the effective filtration area, while allowing the trapped impurities to slide naturally along the arc surface to the discharge hole 42 at the bottom, avoiding the accumulation of impurities on the filter plate and clogging the filter holes; the discharge hole 42 is used to continuously discharge the trapped impurities; the negative pressure airflow generated by the suction fan 38 can carry the separated lightweight fibers through the filter holes of the arc-shaped filter plate 41 into the suction fan 38 to complete the fiber recovery; the conical guide cover is coaxially installed at the air inlet of the suction fan 38, which can gather the airflow, increase the local wind speed, improve the fiber recovery efficiency, and prevent the fibers from accumulating and tangling at the air inlet; The lead of the three-stage variable lead spiral guide 35 changes step by step. The lead is the largest in the pre-resonance section, and the material falls rapidly along the guide to initially adapt to the vibration state of the vertical resonance cavity 31, avoiding sudden strong vibration impact on the material. The lead of the main resonance section is smaller than that of the pre-resonance section, the material falling speed is reduced, and the residence time is extended. Under the action of three-dimensional resonance, the deep separation of fibers and impurities is completed, which is the core working section for opening and removing impurities. The lead of the fine opening section is the smallest, and the material falling speed is the slowest. It performs fine combing and untangling of residual entangled fibers, further improving the opening uniformity.

[0027] The control cabinet 12 is electrically connected to the Z-axis vibrator 39, X-axis vibrator 33, Y-axis vibrator 34, suction fan 38, and drive motor 25 respectively. The control cabinet 12 can independently adjust the frequency and amplitude of each vibrator, the speed of the suction fan 38, and the speed of the drive motor 25. By independently adjusting the operating parameters of each component, the control cabinet 12 can adapt the device to the processing needs of waste textiles of different materials and with different impurity contents. For example, when processing chemical fiber textiles, the excitation frequency can be appropriately increased, and when processing cotton and linen fibers that are easily damaged, the excitation amplitude can be appropriately reduced. The independent adjustment logic of control cabinet 12 is as follows: for different fiber materials such as cotton, linen, and chemical fibers, the frequency and amplitude of the vibrator are adjusted accordingly. Cotton and linen fibers have lower strength, so low frequency and small amplitude parameters are used. Chemical fibers have higher strength, so high frequency and large amplitude parameters can be used. For materials with high impurity content, the speed of the suction fan 38 and the amplitude of the vibrator are increased to enhance the separation and conveying effect. For materials with low impurity content, the operating parameters are reduced to save energy. Control cabinet 12 can realize the linkage start and stop of drive motor 25, each vibrator, and suction fan 38 and the coordinated adjustment of parameters to ensure that the processes of chopping, resonance loosening, impurity removal, and fiber recycling are synchronized and matched, and the device operates stably and efficiently.

[0028] In one embodiment, 2-3 vertical resonant cavities 31 are connected in series. The air outlet of the suction fan 38 of the first-stage cavity is connected to the sleeve 32 of the second-stage cavity. The exciter parameters of each cavity are independently adjustable, corresponding to the coarse opening, medium opening and fine opening stages respectively. It is suitable for processing waste textiles with high entanglement and high impurity content, such as waste carpets and industrial filter cloths.

[0029] In one embodiment, a vibration sensor and a fiber condition detection sensor are installed inside the vertical resonant cavity 31. The sensors are electrically connected to the control cabinet 12. The control cabinet 12 automatically adjusts the frequency and amplitude of each exciter based on the real-time data fed back by the sensors, thereby achieving dynamic matching of the resonance parameters and adapting to the characteristic differences of different batches of materials without manual intervention.

[0030] In one embodiment, a hot air generator is installed at the annular air inlet gap between the sleeve 32 and the discharge pipe 23 to preheat and dry the damp waste textiles simultaneously during the opening and impurity removal process, thereby avoiding the damp fibers from sticking together and affecting the opening effect, and eliminating the need for a separate drying process.

[0031] In one embodiment, the spiral guide 35 is designed as a detachable structure and is connected to the inner wall of the vertical resonant cavity 31 by bolts. Different spiral guides 35 with different leads and cross-sectional shapes can be replaced according to different fiber materials such as cotton, linen, and chemical fibers, so as to further optimize the opening path and residence time of different materials.

[0032] In one embodiment, a multi-stage vibrating screen is installed below the discharge hole 42 to classify and collect impurities according to their particle size and density, thereby achieving the classified recycling of different types of impurities such as metals, sand, and plastics, and improving the comprehensive utilization rate of resources in the waste textile recycling process.

[0033] In operation, the invention works as follows: the drive motor 25 is started by the control cabinet 12, which drives a pair of meshing rotary cutters 24 to rotate synchronously in opposite directions; waste textiles are fed into the feed hopper 21, shredded into uniform small pieces by the rotary cutters 24, and fall into the discharge hopper 22, then through the discharge pipe 23 and the sleeve 32 into the vertical resonance cavity 31; the shredded material is dispersed and enters the pre-resonance section of the spiral guide 35; the control cabinet 12 independently adjusts the frequency and amplitude of the Z-axis vibrator 39, X-axis vibrator 33 and Y-axis vibrator 34, so that the vertical resonance cavity 31 generates three-dimensional composite resonance; the material passes through the pre-resonance section, the main resonance section and the fine opening section along the spiral guide 35 in sequence, and in the pre-resonance section... The fiber gradually adapts to the vibration of the cavity, and is subjected to the strongest three-dimensional resonance force in the main resonance section. The entanglement between the fibers is fully untied, and the fibers and impurities produce different vibration responses due to the difference in their inherent frequencies, achieving efficient separation. The final fine untangling is completed in the fine opening section. The air spring 37 supports the cavity and buffers the vibration, ensuring the stability of the cavity resonance, while isolating the transmission of vibration. The suction fan 38 generates negative pressure airflow, which is gathered by the conical guide cover. The separated fibers are carried through the filter holes of the arc-shaped filter plate 41 and enter the suction fan 38 for recycling. Impurities with higher density and larger size are intercepted by the arc-shaped filter plate 41, slide down the arc surface to the bottom of the extension, and are finally discharged from the discharge hole 42.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
