Description

Technical Field

[0001] This utility model relates to the technical field of plastic recycling devices, specifically to a plastic waste recycling and processing device. Background Technology

[0002] In chemical polymer material production workshops, the processing of plastic products typically generates a large amount of trimmed scrap. Directly discarding this waste not only wastes resources but also increases the environmental burden. Therefore, recycling this waste has become a common industry practice. Recycled waste is usually crushed into granules, but its physical properties, such as strength and heat resistance, differ significantly from the original raw materials, often being inferior or weaker. In actual processing, minor losses often occur due to plastic adhering to equipment walls or conveying pipelines during the melting process. Although these losses are small, they accumulate and affect the utilization rate of raw materials. To compensate for this loss, a small amount of waste can be added to the original material. Since the amount of waste added is usually controlled within 5%-7%, not exceeding 10%, and the waste particles mix evenly with the original material during melting, this minor addition will not significantly change the overall performance and quality of the final product, thus achieving the rational utilization of waste while ensuring product quality.

[0003] However, existing waste recycling and processing equipment has significant structural defects, particularly the often separate design of the waste hopper and the lid of the plastic heating container, leading to a lack of effective coordination between the loading and unloading processes. When operators need to move the lid open to observe the melting state of the material inside the heating container, they must first stop the discharge pipe above the waste hopper. Otherwise, because the waste hopper is not fixed to the lid, the lid's opening will cause misalignment between its outlet and the container's inlet, resulting in some of the continuously falling waste spilling outside the lid instead of entering the container. This not only wastes materials but, more seriously, when the addition of waste needs to be quantitatively controlled, this misalignment leads to a reduction in the actual amount of waste mixed in, making it impossible to accurately maintain the preset waste ratio. Consequently, insufficient waste mixing cannot effectively compensate for losses during processing. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic waste recycling and processing device. By integrating the waste hopper with a movable cover and supplementing it with a dust collection device, a highly efficient recycling system is constructed to achieve continuous, accurate, and clean recycling of plastic waste. This effectively compensates for processing losses, improves resource utilization, and ensures the stable quality of the final product.

[0005] To achieve the above objectives, the present invention proposes the following technical solution:

[0006] A plastic waste recycling and processing device includes a heating container, the top of which is an open structure and can be opened and closed by a horizontally movable cover. The cover has an inlet that communicates with the interior of the heating container.

[0007] A waste hopper is fixed to the cover so that the waste hopper moves synchronously with the cover.

[0008] The waste hopper is provided with a discharge port at the bottom, and the discharge port is always aligned with the inlet.

[0009] As a preferred technical solution of the utility model, the longitudinal section of the waste hopper is triangular or trapezoidal.

[0010] As a preferred technical solution of the utility model, the longitudinal section of the waste hopper is a non-equilateral triangular structure, having a long hypotenuse and a short hypotenuse, the long hypotenuse and the short hypotenuse intersecting at the apex of the bottom end, and the discharge port is provided at the apex.

[0011] As a preferred technical solution of the utility model, it also includes a dust collection device;

[0012] The dust collection device includes a dust collection hood, an exhaust pipe, and a fan. The dust collection hood is provided with a dust collection port, the exhaust pipe is connected to the dust collection port, and the fan is mounted on the exhaust pipe.

[0013] A dust removal port is provided on the lower part of the side wall of the waste hopper;

[0014] The dust suction hood is installed on the side wall of the heating container near the dust removal port, and the dust suction port is positioned corresponding to the dust removal port.

[0015] As a preferred technical solution of the utility model, a filter screen is provided at the dust removal port.

[0016] As a preferred technical solution of the utility model, it also includes a storage tank, which is set directly above the waste hopper by a support frame. The bottom end of the storage tank is provided with a discharge pipe, and the bottom outlet of the discharge pipe extends into the interior of the waste hopper.

[0017] As a preferred technical solution of the utility model, a mounting bracket is fixedly provided on the outer wall of the storage tank, and the storage tank is mounted on the support frame through the mounting bracket;

[0018] The mounting bracket is provided with at least three support components;

[0019] Each of the aforementioned support components includes:

[0020] A movable pressure rod, the upper end of which is connected to the mounting bracket, and the lower end of which is provided with a contact head;

[0021] A guide sleeve is vertically mounted on the support frame, and the lower part of the movable pressure rod extends into the guide sleeve and can slide along its axial direction;

[0022] A spring is fitted onto the movable pressure rod and housed within the guide sleeve. The upper end of the spring acts on the movable pressure rod, and the lower end acts on the guide sleeve or the support frame, to provide an upward preload support force for the movable pressure rod.

[0023] It also includes a weighing sensor corresponding to the number of the support components, each of the weighing sensors being mounted on the support frame and located directly below the corresponding guide sleeve;

[0024] The preload of the spring ensures that when the storage tank is unloaded, a set gap is maintained between the contact head of the movable pressure rod and the force point of the weighing sensor; when the storage tank is loaded, the mounting bracket drives the movable pressure rod to move downward against the preload of the spring, so that the contact head presses firmly onto the corresponding weighing sensor.

[0025] As a preferred technical solution of the utility model, it also includes a stirring device;

[0026] The stirring device includes a motor, a stirring shaft, and stirring blades. The motor is located at the bottom of the heating container, the stirring shaft extends upward from the output end of the motor and penetrates into the interior of the heating container, and the stirring blades are connected to the outer wall of the stirring shaft.

[0027] As a preferred technical solution of the utility model, the bottom of the heating container is provided with a support base, which is a hollow cylindrical or square frame structure, reserving installation space for the motor.

[0028] As can be seen from the above technical solutions, the present invention provides a plastic waste recycling and processing device, which has the following beneficial effects:

[0029] 1. By integrating the waste hopper with the movable cover, the defects of the traditional split design are fundamentally solved. This ensures that when the cover is moved open to observe the internal working conditions, the discharge port of the waste hopper and the inlet of the cover remain aligned without interrupting the feeding process. This enables parallel operation of observation and feeding, and ensures the accuracy of the waste mixing ratio.

[0030] 2. Through the aforementioned precise and continuous feeding, the actual amount of waste material added can be guaranteed to strictly conform to the preset doping ratio, effectively compensating for the slight loss of the main material during processing. This effectively avoids formula deviations caused by insufficient waste material addition or spillage, thus ensuring the overall performance and quality stability of the final product while utilizing waste materials.

[0031] 3. It avoids the spillage and waste of waste material caused by misalignment of the feed inlet and discharge outlet, so that all metered waste material can be effectively utilized. At the same time, it accurately compensates for processing losses and reduces the extra consumption of positive material, thereby significantly improving the utilization rate of raw materials, reducing production costs, and achieving better economic benefits.

[0032] 4. The integrated dust collection device promptly extracts and collects the dust generated during the fall of waste materials, effectively preventing the spread of dust in the workshop, maintaining a clean production environment, meeting the requirements of clean production, and protecting the health of operators.

[0042] To address the problems of traditional separate hopper and cover designs, which necessitate interrupting feeding to monitor operating conditions and lead to spillage and inaccurate mixing due to misalignment, this invention provides a plastic waste recycling and processing device. Figure 1-2 As shown, it mainly includes a heating container 1, a waste hopper 2, a storage tank 3, and a dust collection device.

[0043] The heating container 1 is used to heat and melt plastic raw materials. It has an open top and is opened and closed by a horizontally movable cover 4. The cover 4 has a feed port that connects to the inside of the heating container 1 and is used to pour waste particles into the heating container 1.

[0044] When it is necessary to observe the molten state of the material inside the heating container 1, the operator can drive the cover 4 to move horizontally relative to the top opening of the heating container 1, thereby partially opening the heating container 1 and exposing the observation port. The stroke of this translation is sufficient for the operator to clearly observe the state of the internal material, while avoiding excessive heat loss due to an excessively large opening.

[0045] The waste hopper 2 is fixed to the cover 4, and has a discharge port at its bottom for conveying waste particles into the heating container 1. The longitudinal section of the waste hopper 2 is a triangle or trapezoid with a wider top and narrower bottom, which facilitates the concentrated falling of waste. Preferably, the longitudinal section of the waste hopper 2 is a non-equilateral triangle structure with a long hypotenuse and a short hypotenuse, which intersect at the apex of the bottom, which is the location of the discharge port. The bottom of the waste hopper 2 is connected to the cover 4 by welding, screwing, or other fixed methods, so that the discharge port and the feed port on the cover 4 are always aligned. The long hypotenuse serves as the main waste receiving surface, and the waste slides down the inner wall from its upper part to the discharge port; the lower part of the short hypotenuse is provided with a dust removal port 11 and equipped with a filter screen to prevent the main waste particles from being sucked away, while allowing dust to be sucked in.

[0046] The long, beveled edge, serving as the primary waste receiving surface, provides a longer sliding path and a gentler inclination angle. This facilitates a more stable and uniform flow of waste particles towards the discharge port under gravity, reducing the risk of blockage or accumulation. In contrast, the short, beveled edge shortens the residence time of waste on the other side, preventing uneven distribution of waste within the hopper. This flow-guiding design ensures that waste continues to flow accurately and continuously through the discharge port into the heating container during the translation of the cover 4, enabling parallel operation of observation and feeding. This solves the problems of spillage and inaccurate mixing caused by misalignment in traditional split designs.

[0047] The bottom of the waste hopper 2 is integrally fixed to the cover 4, allowing the waste hopper to move synchronously with the cover 4, thus solving the inherent defects of traditional separate hopper and cover structures. Specifically, firstly, it enables parallel operation of observation and feeding. When it is necessary to slide and open the cover 4 to observe the inside of the heating container 1, the feeding process of the discharge pipe 5 above the waste hopper 2 does not need to be interrupted. Because the waste hopper 2 moves with the cover 4, its discharge port and the inlet of the cover 4 remain connected and aligned, ensuring that the waste continuously and accurately falls into the heating container 1. Secondly, it ensures the accuracy of the waste mixing ratio, avoiding the problem of waste spilling outside the heating container 1 due to misalignment of the discharge port and inlet caused by the movement of the cover 4. This is crucial for precision production that requires precise control of the waste mixing ratio, ensuring the accuracy of formula execution, and thus using waste to compensate for the processing loss of the main material without compromising the overall performance of the final product.

[0048] Optionally, the waste hopper 2 and the cover 4 can be fixed by means other than welding, such as riveting or threaded connection, as long as the synchronicity of the two during movement can be guaranteed.

[0049] A storage tank 3 is located above the waste hopper 2. The storage tank 3 is positioned directly above the waste hopper 2 via a support frame 6 and is used to store and measure the weight of waste. The bottom of the storage tank 3 has an arc-shaped or conical structure, and a discharge pipe 5 is provided at its bottom end. The bottom outlet of the discharge pipe 5 extends into the interior of the waste hopper 2. Even when the cover 4 is moved a certain distance, the bottom outlet of the discharge pipe 5 will not detach from the waste hopper 2. However, this does not mean that the bottom end of the discharge pipe 5 is fixed to the waste hopper 2, but only extends into the waste hopper 2. The top of the storage tank 3 is provided with a feed pipe 7 for receiving waste particles transported from the outside.

[0050] To measure the weight of the waste material inside the storage tank 3, a weighing sensor is also provided. Specifically, a rigid mounting bracket is fixed to the outer perimeter of the lower side wall of the storage tank 3 (near its conical or arc-shaped bottom transition area). The mounting bracket is designed as a circular or square ring structure according to the shape of the storage tank 3, and is firmly connected to the outer wall of the storage tank 3 by welding or bolting. The storage tank 3 is then mounted on the support frame 6 via this mounting bracket. The mounting bracket has at least three support components, each of which includes a movable pressure rod, a guide sleeve, and a spring, which are connected in combination. The upper end of the movable pressure rod is connected to the mounting bracket, the guide sleeve is vertically mounted on the support frame 6, and its lower end is fixed to the receiving surface (specifically the top surface) of the support frame 6. The lower part of the movable pressure rod extends into the guide sleeve and can slide along its axial direction. The bottom end of the movable pressure rod is provided with a contact head, which is used to contact the weighing sensor. The sliding fit between the guide sleeve and the movable pressure rod allows vertical movement while providing necessary horizontal limits, ensuring the rigid stability of the storage tank 3 installation and achieving accurate weighing by the load cells. The spring is fitted onto the movable pressure rod and housed within the guide sleeve. The upper end of the spring acts on the movable pressure rod, for example, its upper end resting on a shoulder of the movable pressure rod, and the lower end of the spring acts on the bottom of the guide sleeve or the support frame 6, for example, its lower end resting on a fixed step inside the guide sleeve or the receiving surface of the support frame 6. The spring provides an upward preload support force to the movable pressure rod. The number of load cells corresponds to the number of support components, and they are installed on the receiving surface of the support frame 6 and located directly below the guide sleeve. By adjusting the preload support force of the springs, a set small gap is maintained between the bottom surface of the contact head of the movable pressure rod and the force point of the load cell when the storage tank 3 is unloaded. At this time, the total weight of the storage tank 3 and the mounting bracket is mainly borne by the preload support force of each spring, and the load cells are not subjected to pressure. When waste is added to storage tank 3, the increase in the total weight of the tank causes a slight sinking of the mounting bracket. This sinking causes the movable pressure rods of each support component to move downwards against the force of the springs. When the displacement exceeds the preset gap, the contact head presses against the weighing sensor, and the weight of the tank distributed to that support component is then measured by the weighing sensor. During discharge, the process is reversed; the weight reduction causes the movable pressure rods to rise under the action of the springs, eventually causing the contact head to disengage from the weighing sensor. During the process of conveying waste to storage tank 3 through feed pipe 7, the weighing sensor monitors the waste quality. When the preset quality value is reached, feeding stops, thereby achieving accurate measurement of the waste. As the upstream feeding unit of the waste hopper, storage tank 3 not only continuously provides waste to the waste hopper but also ensures, through the weighing sensor, that the amount of waste added to heating container 1 each time meets the mixing ratio required by the process.

[0051] The waste addition process is as follows:

[0052] First, the storage tank 3 stops feeding after accommodating a preset amount of waste particles. Then, the heating container 1 is filled with an appropriate amount of waste material and heating begins. Next, the discharge pipe 5 is opened, allowing the waste material in the storage tank 3 to fall into the waste hopper 2. This waste material then continuously and evenly enters the heating container 1 through the outlet of the waste hopper 2 and the inlet of the cover 4, until all the waste material in the storage tank 3 is discharged. During this process, because the waste hopper 2 and the cover 4 are integrally fixed, even when the cover 4 needs to be moved open to observe the internal state of the heating container 1, it is not necessary to close the discharge pipe 5. The waste hopper 2 moves synchronously with the cover, and its outlet remains aligned with the inlet of the cover 4. This ensures that the waste material can still fall accurately and continuously into the heating container 1 during observation, avoiding spillage or deviations in the amount of waste material due to misalignment, effectively guaranteeing the accuracy of the waste material mixing ratio and the stability of the process.

[0053] Through the above structural design and process coordination, this utility model realizes the parallel operation of quantitative control of waste materials, continuous feeding and real-time observation, which improves recycling efficiency while ensuring the consistency of product quality and maximizing the utilization rate of raw materials.

[0054] The dust collection device is used to collect dust from plastic waste particles and maintain a clean workshop environment. The dust collection device includes a dust hood 8, an exhaust pipe 9, and a fan 10. The dust hood 8 is located on one side of the dust collection port of the waste hopper 2, preferably integrally formed with the side wall of the heating container 1. The dust hood 8 is cone-shaped and has a dust collection port, the position of which corresponds to the dust collection port of the waste hopper 2 to ensure effective dust extraction. The dust collection port 11 is located at the lower part of the shorter inclined side, corresponding to the position of the dust hood 8, and is designed based on the behavior characteristics of dust in the flow of waste. When waste slides down the longer inclined side, light dust is generated due to collisions and friction between particles. This dust easily accumulates on the shorter inclined side under the action of airflow and gravity, because the space on the shorter inclined side is relatively compact, and the dust is more easily concentrated. The dust hood 8 is located on the shorter inclined side, allowing it to be closer to the dust source and directly capture the dust through negative pressure suction, preventing it from spreading into the workshop environment. Meanwhile, the filter screen at dust collection port 11 prevents the main particles of waste material from being accidentally sucked in, ensuring that only dust is collected.

[0055] The exhaust pipe 9 is connected to the side of the dust suction port away from the dust removal port 11. The fan 10 can be set in the exhaust pipe 9 or other suitable positions, such as the end or middle of the exhaust pipe 9. As long as a negative pressure can be formed in the dust suction hood 8 through the exhaust pipe 9 and the dust suction port, the dust removal port 11 can be used to draw the dust into the waste hopper 2.

[0056] As plastic waste granules roll from top to bottom in the waste hopper 2, the blower 10 starts, creating a negative pressure inside the dust collection hood 8 through the exhaust pipe 9 and the dust suction port. This negative pressure acts on the inside of the waste hopper 2 through the dust removal port 11, drawing in splashed light dust into the dust collection hood, which is then discharged and collected through the exhaust pipe 9. Simultaneously, the waste granules enter the heating container 1 through the discharge port and the feed port. This design cleverly utilizes the structure of the waste hopper 2 itself as part of the dust removal channel, promptly removing dust that affects product quality and the operating environment without affecting the main material flow. At the same time, the filter screen prevents the accidental suction of qualified waste granules, ensuring recycling efficiency.

[0057] Optionally, the fan 10 is a variable frequency fan so that the suction force can be adjusted according to the actual amount of dust.

[0058] The bottom of the heating container 1 is fixed to the ground or base by a support 12. The support 12 is a hollow cylindrical or square frame structure. Its function includes at least raising the heating container 1 to a suitable working height and reserving sufficient installation space for other components such as stirring devices installed at the bottom. At the same time, its frame structure can play a certain role in shock absorption, buffering the vibration generated by stirring and other operations, and improving the overall stability of the equipment.

[0059] The stirring device includes a motor 13, a stirring shaft, and stirring blades. The motor 13 is mounted on the bottom of the heating container 1 via a mounting base, located within the installation space formed by the support base 12 and the bottom wall of the heating container 1. The stirring shaft extends upward from the motor output end, passes through the bottom of the heating container 1, and extends into the container. Stirring blades are connected to the outer wall of the stirring shaft inside the heating container 1 for mechanically stirring the plastic raw materials and waste particles during the melting process, promoting uniform mixing and heating.

[0060] In this embodiment of the invention, the motor 12 is configured as a bottom-mounted structure. Firstly, this arrangement avoids placing the motor 13 and its transmission mechanism on top of the cover 4 or container, thus preventing interference from the motor 13 and its connecting components when the cover 4 needs to be opened horizontally for observation or maintenance, ensuring smooth operation and equipment accessibility. Secondly, a bottom-mounted motor 13 helps lower the overall center of gravity of the equipment, enhancing operational stability, especially during high-intensity stirring operations, effectively suppressing vibration and improving the overall rigidity of the equipment. Furthermore, this structure facilitates independent maintenance and heat dissipation of the motor 13, preventing the high-temperature melting environment from affecting the motor 13.

[0061] Through the coordinated configuration of the above-mentioned stirring device with components such as heating container 1 and support base 12, this utility model achieves efficient mixing while also taking into account ease of operation, structural stability and ease of maintenance, further enhancing the practicality and reliability of the equipment.

[0062] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
