Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of plastic recycling, and in particular relates to a plastic regenerative resource utilization pretreatment device. BACKGROUND

[0002] With the continuous growth of global plastic consumption, the recycling of plastic waste has become a key way to alleviate resource shortage and environmental pollution. Among them, PET beverage bottles, PE chemical bottles and other plastic bottle waste have become the core processing object in the field of plastic recycling due to their large output and high recycling value. In the plastic bottle recycling process, the pretreatment link (including crushing, impurity removal, draining and other processes) directly determines the subsequent granulation quality and recycling efficiency.

[0003] The moisture control of plastic bottle crushing pretreatment is a core pain point in the field of plastic recycling, but some problems are found in actual use: after the plastic bottle is crushed, a large amount of debris remains in the arc or bowl-shaped concave surface. In the subsequent crushing, cooling water, residual liquid and environmental moisture will be stored in the concave surface. The concave surface of the thick wall debris will also form deep water locking, and the crushed debris will form a mountain-shaped pile. The bottom layer of debris is compressed and the gap is closed. The middle layer of water flows horizontally and is adsorbed again. The top layer of infiltrated water is intercepted, showing a top layer of fast drying and a middle and bottom layer of moisture. When the water-containing debris is granulated, air bubbles are easily produced, resulting in scrap particles and affecting the recycling effect.

The staggered, gradually varying-height disturbance plates, linked by gears and push rods, dynamically adjust their angle, forcing the rotation of arc-shaped or bowl-shaped concave debris. This not only allows free water trapped within the concave surface to escape smoothly but also, through slight compression, promotes the seepage of deep-seated water within the gaps of thick-walled debris concave surfaces. This solves the problem of traditional devices being unable to effectively handle deep-seated water retention, reducing the moisture content of the debris and eliminating the risk of air bubbles causing granule rejection in subsequent granulation processes. Simultaneously, through the top… The differentiated swing design of the lifting plate precisely addresses the issue. After the tilting frame is tilted, the end of the lifting plate at its lowest point can generate a larger amplitude of up-and-down swing, forming a wave-like undulation with significant undulation at the end and gentle undulation at the near end. This not only strongly opens up the gaps between particles in the bottom layer of debris that have closed due to heavy pressure, creating sufficient channels for water penetration, but also pushes the dense debris in the middle layer to change the flow direction, reducing the probability of water being re-adsorbed by the concave surface of the arc-shaped debris when it flows laterally along the slope. This completely breaks the obstacle of the mountain-like pile to the draining, achieving uniform drying of debris from the top to the bottom layer.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application, and the following embodiments are used to illustrate the present application.

[0021] Embodiment 1: As shown in FIG. Figures 1 to 10 A plastic recycling resource utilization pretreatment device includes a frame 1.

[0022] A roller crusher 12 is installed on the frame 1, and a collection box 13 is installed at the discharge port of the roller crusher 12; A synchronization frame 2 is vertically inserted into the collection box 13. A tilting frame 211 is rotatably installed on the side wall of the collection box 13. A slider 22 is rotatably installed on the tilting frame 211 and is slidably connected to the synchronization frame 2. A filter hole 212 is opened on the tilting frame 211. A plunger 213 is installed at the bottom of the collection box 13 and is movably inserted into the filter hole 212. When the synchronization frame 2 moves upward, it causes the tilting frame 211 to deflect, guiding the raw material to both sides and opening the filter hole 212. Multiple pairs of lifting plates 23 are installed at the rotation center of the slider 22, and the lifting plates 23 are placed on the tilting frame 211. Gears 232 are installed on the lifting plates 23. During the sliding process, the slider 22 drives the gears 232 to mesh with the rack 233 installed at the bottom of the timing frame 2, so that the surface of the tilting frame 211 is wavy. Each lifting plate 23 is equipped with several pairs of disturbance plates 3 that rotate alternately. The height of the disturbance plates 3 near the center of rotation gradually decreases, as does the height of the disturbance plates 3 near the outer edges. A top rod 32 is horizontally slidably mounted at the bottom of each disturbance plate 3. The rotation of the gear 232 drives the top rod 32 to move, thereby changing the angle of the disturbance plate 3. The linkage of the synchronous frame 2, the tilting frame 211, and the slider 22 enables the material to be guided and the filter holes 212 to open and close, providing a basic channel for moisture discharge. The cooperation between the lifting plate 23, the gear 232, and the rack 233 makes the surface of the tilting frame 211 wavy, which can break up the mountain-like pile of debris. The staggered distribution and gradually changing height design of the disturbance plates 3, combined with the drive of the top rod 32, can adapt to different amounts of debris accumulation in different areas, laying a structural foundation for subsequent forced tilting of debris and removal of moisture.

[0023] like Figures 1 to 10 As shown, in a specific embodiment, a pair of reinforcing ribs 11 are vertically installed on the frame 1. Cross ribs 111 are installed on the side walls of the pair of reinforcing ribs 11. A horizontal rib 121 is installed on the top reinforcing rib 11, and the horizontal rib 121 is connected to the outer shell of the roller crusher 12. A support leg 131 is installed on the bottom reinforcing rib 11, and the support leg 131 is connected to the bottom of the collection box 13. The cooperation of the reinforcing ribs 11 and the cross ribs 111 enhances the overall structural stability of the frame 1. The horizontal rib 121 ensures the roller crusher 12 is firmly installed, and the support leg 131 provides stable support for the collection box 13, preventing component displacement due to vibration during operation, ensuring the accuracy of the linkage between various structures, and extending the service life of the equipment.

[0024] like Figures 1 to 10As shown, furthermore, a mounting plate 122 is welded to the bottom of the roller crusher 12. The mounting plate 122 is connected to the outer shell of the collection box 13 by bolts. A drain pipe 132 is installed at the bottom of the collection box 13, and a cover plate 133 is also installed on the surface of the collection box 13 by bolts. Opening the cover plate 133 facilitates the later cleaning of raw materials. A handle 134 is installed on the cover plate 133, and an anti-slip sleeve is installed on the surface of the handle 134. The mounting plate 122 connects the roller crusher 12 and the collection box 13 by bolts, which facilitates later disassembly and maintenance. The drain pipe 132 realizes the centralized discharge of drained water, preventing water from accumulating in the collection box 13. The design of the cover plate 133 and the handle 134 makes it convenient for operators to open the collection box 13 to clean residual raw materials, reducing the difficulty of equipment maintenance and improving practicality.

[0025] Example 2: The difference between the above embodiments and this embodiment is that: Figures 1 to 10 As shown, an electric push rod 21 is installed at the bottom of the collection box 13. The output rod of the electric push rod 21 is movably connected to the collection box 13, and the output end of the electric push rod 21 is connected to the center position of the synchronous frame 2. The filter hole 212 and the plunger 213 are arc-shaped, and the center of curvature is the same as the rotation center of the tilting frame 211 and the collection box 13. The electric push rod 21 provides precise power for the lifting and lowering of the synchronous frame 2, replacing manual drive, improving the automation level of the device, and ensuring that the lifting and lowering range of the synchronous frame 2 is controllable. The arc-shaped filter hole 212 and the plunger 213, in conjunction with the rotation center of the tilting frame 211, ensure that the plunger 213 and the filter hole 212 maintain a stable movable insertion relationship during the deflection of the tilting frame 211, avoiding debris leakage or poor water drainage.

[0026] like Figures 1 to 10 As shown, in a specific embodiment, a slide plate 222 is mounted on the slider 22. A guide rod 223 is installed through the slide plate 222. A guide seat 224 is mounted on one end of the guide rod 223 and welded to the side wall of the synchronous frame 2. A guide plate 225 is mounted on the other end of the guide rod 223. The diameter of the guide plate 225 is larger than the diameter of the guide rod 223. A compression spring 226 is sleeved on the guide rod 223. One end of the compression spring 226 is engaged with the guide seat 224, and the other end is engaged with the slide plate 222. The cooperation between the slide plate 222 and the guide rod 223 provides guidance for the sliding of the slider 22, ensuring that the slider 22 moves along a fixed trajectory and avoiding deviation that affects the deflection of the flipping frame 211. The guide plate 225 prevents the slide plate 222 from falling off the guide rod 223, and the compression spring 226 can buffer the impact force when the slider 22 slides, reduce the wear between the slider 22 and the synchronous frame 2, and ensure the long-term stable operation of the components.

[0027] like Figures 1 to 10As shown, further, the slider 22 is rotatably connected with the synchronous shaft 221, the synchronous shaft 221 is rotatably connected with the gear 232, the synchronous shaft 221 is sleeved with the torsional spring 323, one end of the torsional spring 323 is clamped on the side wall of the turnover frame 211, the other end of the torsional spring 323 is clamped on the side wall of the gear 232, the connecting frame 231 is rotatably connected with the side wall of the jacking plate 23, and the jacking plate 23 is attached to the turnover frame 211, the fixed frame 234 is rotatably connected with the rack 233, and the fixed frame 234 is rotatably connected with the synchronous frame 2. The synchronous shaft 221 realizes synchronous rotation of the slider 22, the turnover frame 211 and the gear 232, ensuring the coordination of each component; the elastic force of the torsional spring 323 ensures that the gear 232 and the rack 233 are always stably engaged, avoiding disconnection of transmission, ensuring the continuity of the up-down movement of the jacking plate 23; the connecting frame 231 ensures that the rotation of the gear 232 can accurately drive the jacking plate 23 to move, the fixed frame 234 fixes the position of the rack 233, improves the stability of the transmission structure, and ensures the regular formation of the wave-shaped undulation on the surface of the turnover frame 211.

[0028] Embodiment 3: Different from the above embodiments and the present embodiment is that, as shown in the figure, Figures 1 to 10 The rotating center of the disturbance plate 3 is rotatably connected with the positioning shaft 31, the bottom of the positioning shaft 31 is rotatably connected with the rocker arm 311, the inner cavity of the disturbance plate 3 is rotatably connected with the rocker arm 311, a strip-shaped groove 312 is formed in the rocker arm 311, a sliding rod 313 is slidably arranged in the strip-shaped groove 312, and the sliding rod 313 is rotatably connected with the top rod 32. The positioning shaft 31 provides a fixed rotating center for the rotation of the disturbance plate 3, ensuring the stability of the angle adjustment of the disturbance plate 3; the cooperation of the rocker arm 311, the strip-shaped groove 312 and the sliding rod 313 converts the horizontal sliding of the top rod 32 into the rotation of the rocker arm 311, and then drives the angle adjustment of the disturbance plate 3, realizing the accurate conversion of "linear motion-rotary motion", ensuring that the disturbance plate 3 can effectively overturn the arc-shaped debris.

[0029] As shown in the figure, Figures 1 to 10 In the specific embodiment, the top rod 32 is rotatably connected with the top block 324, the top block 324 is in the shape of a boss, the top rod 32 is sleeved with the reset spring 325, one end of the reset spring 325 is clamped on the side wall of the top block 324, and the other end of the reset spring 325 is clamped on the side wall of the jacking plate 23. The top block 324 provides a stable clamping position for the reset spring 325, avoiding displacement of the reset spring 325; the reset spring 325 can drive the top rod 32 to reset quickly after the top rod 32 completes the pushing action, preparing for the next angle adjustment of the disturbance plate 3, ensuring the continuity of the action of the disturbance plate 3, improving the overturning efficiency of the arc-shaped debris, and ensuring the water removal effect.

[0030] As shown in the figure, Figures 1 to 10As shown, further, the top rod 32 is provided with a protrusion 321 at the end, the gear 232 is provided with a pressing arm 322, the pressing arm 322 rotates synchronously with the gear 232, and the protrusion 321 is attached to the side wall of the pressing arm 322, and the pressing arm 322 drives the top rod 32 to slide. The protrusion 321 and the pressing arm 322 are attached to each other, and the rotation of the gear 232 is converted into the horizontal sliding of the top rod 32, realizing the transmission conversion of “rotary motion-linear motion”, and the top rod 32 can be driven without additional power source, simplifying the structure of the device and reducing energy consumption; at the same time, the gear 232 drives the lifting plate 23 and the pressing arm 322 to move synchronously, ensuring that the wave-shaped fluctuation of the lifting plate 23 and the angle adjustment of the disturbance plate 3 are coordinated, and improving the overall draining efficiency of the device.

[0031] The implementation principle of the plastic recycling resource pretreatment device is as follows: During the plastic bottle recycling pretreatment, the plastic bottles to be treated are first put into the roller crusher 12, and the cutting and crushing action of the roller crusher 12 produces plastic debris with arc or bowl-shaped concave surface. These debris directly fall from the discharge port of the roller crusher 12 onto the turnover frame 211 in the collection box 13 below. In the initial state, the turnover frame 211 maintains a horizontal posture, and the plunger 213 at the bottom of the collection box 13 is just inserted into the filter hole 212 on the turnover frame 211, realizing the sealing of the filter hole 212, effectively preventing the crushed plastic debris from leaking out of the filter hole 212, and ensuring that the debris can be completely stacked on the surface of the turnover frame 211.

[0032] When it is necessary to perform draining operation on the accumulated plastic debris to solve the problem of water retention, the device is started to drive the synchronous frame 2 to move vertically upward along the collection box 13. The movement of the synchronous frame 2 is powered by the electric push rod 21 installed at the bottom of the collection box 13. The output rod of the electric push rod 21 penetrates through the collection box 13 and is fixedly connected to the center of the synchronous frame 2, and the lifting of the synchronous frame 2 is accurately controlled by the extension and retraction of the output rod of the electric push rod 21. During the upward movement of the synchronous frame 2, the sliding block 22 connected thereto moves synchronously, and the sliding block 22 is rotationally connected to the turnover frame 211. Therefore, the movement of the sliding block 22 will cause the turnover frame 211 to deflect around the rotation center of the turnover frame 211 and the side wall of the collection box 13, so that the originally horizontal turnover frame 211 gradually forms an inclined state. This inclination design can guide the plastic debris to flow to both sides of the turnover frame 211 by gravity, and at the same time, the plunger 213 and the filter hole 212 are gradually separated when the turnover frame 211 is deflected, and the filter hole 212 is opened, providing a channel for water discharge. The water in the debris can naturally drip through the filter hole 212 to the bottom of the collection box 13, and finally be collected and discharged through the drain pipe 132 at the bottom of the collection box 13, completing the preliminary water discharge.

[0033] In the process of sliding the slider 22 with the synchronous frame 2, the gear 232 rotationally mounted on the slider 22 will form meshing transmission with the rack 233 mounted on the bottom of the synchronous frame 2 through the fixed frame 234. The gear 232 rotates under the action of the rack 233, and the gear 232 is fixedly connected with the jacking plate 23 through the connecting frame 231, and the jacking plate 23 is attached to the surface of the turnover frame 211, wherein the swing angle of the distal end of the jacking plate 23 (i.e. the lowest point of the turnover frame 211 after tilting) is greater than that of the proximal end. Since the lowest point of the turnover frame 211 is the area where the plastic debris naturally accumulates the most after tilting, the debris in this area is more likely to form a dense mountain-shaped pile bottom layer due to gravity compression, therefore, through the transmission cooperation of the gear 232 and the connecting frame 231, the gear 232 rotation will drive the distal end of the jacking plate 23 to swing up and down with a larger amplitude, thereby forming a regular wave-shaped fluctuation along the surface of the turnover frame 211, with the distal end fluctuating more significantly and the proximal end fluctuating more gently. This differentiated wave-shaped fluctuation can more accurately act on the debris accumulation area: for the lowest point of the turnover frame 211 with the most debris, a larger swing angle can generate a stronger loosening force to directly break the compact mountain-shaped pile structure formed by the dense accumulation of debris in this area. Overall, on the one hand, it can strongly separate the inter-particle gaps closed by the bottom layer debris due to heavy pressure, creating sufficient channels for water penetration and avoiding water accumulation in the bottom layer; on the other hand, the larger amplitude fluctuation at the distal end can also push the dense middle layer debris to quickly change the flow direction, reducing the probability of water being re-adsorbed by the arc-shaped debris concave surface when flowing horizontally along the slope, thereby structurally addressing the core problem of mountain-shaped piles hindering drainage.

[0034] Meanwhile, the gear 232 rotates the compression arm 322 installed on the side wall of the gear 232 synchronously. The compression arm 322 continuously extrudes the protrusion 321 at the end of the jacking rod 32 during rotation, thereby driving the jacking rod 32 to slide horizontally along the jacking plate 23. The end of the jacking rod 32 away from the protrusion 321 is fixedly connected with the sliding rod 313, which is slidingly embedded in the strip-shaped slot 312 of the rocker arm 311. The rocker arm 311 is rotationally connected with the disturbance plate 3 through the positioning shaft 31 and is arranged in the inner cavity of the disturbance plate 3. Therefore, the horizontal sliding of the jacking rod 32 drives the sliding rod 313 to move in the strip-shaped slot 312, thereby driving the rocker arm 311 to rotate around the positioning shaft 31, and finally achieving dynamic adjustment of the angle of the disturbance plate 3. Since the disturbance plates 3 are staggered on the jacking plate 23 and the height of the disturbance plates 3 near the rotation center and the outer side gradually decreases, the disturbance plates 3 can adapt to the amount of debris accumulation in different areas of the turnover frame 211, ensuring that the arc-shaped debris at each position can be fully turned and stirred by the disturbance plates 3. This stirring effect can force the arc-shaped debris to change its posture, so that the debris originally stored with the concave surface upward is turned to the concave surface downward, and the water stored in the concave surface is smoothly discharged. In addition, for the deep water locking in the gap of the concave surface of the thick-walled arc-shaped debris, the stirring of the disturbance plates 3 also has a slight extrusion effect, which promotes the deep water to seep out, thereby completely solving the water storage problem of the arc-shaped debris.
