Description

Technical Field

[0001] This utility model relates to the field of waste collection and sorting technology, specifically to an automatic waste collection and sorting device. Background Technology

[0002] With the widespread use of plastic products in packaging, construction, electronics, and other fields, the amount of plastic waste generated has increased dramatically. Existing sources of plastic waste are extremely diverse, encompassing packaging materials from daily life, scraps from industrial production processes, and discarded electronic product casings. These wastes are complex in composition, containing not only various plastic components such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC), but also small amounts of metallic impurities such as iron and aluminum. Because the recycling processes and values ​​of different types of plastics and metals differ significantly, if metallic impurities cannot be effectively separated from various plastic components, it will not only reduce the quality of recycled plastic products but also cause wear and tear on subsequent processing equipment, severely impacting the resource utilization efficiency of plastic waste.

[0003] In the current waste recycling and processing field, manual sorting remains the main sorting method. This traditional method relies on manual operation and has many drawbacks. First, manual sorting is extremely inefficient and cannot meet the ever-increasing demand for plastic waste processing. Second, high labor costs greatly compress the profit margins of recycling companies. In addition, the accuracy of manual sorting is greatly affected by the operator's subjective factors and fatigue level, resulting in inconsistent sorting effects and making it difficult to achieve fine separation.

[0004] More importantly, manual sorting is prone to missing metal materials that are wrapped or attached to the waste, resulting in some metal resources not being effectively recycled. This not only wastes resources, but the residual metal can also interfere with the subsequent plastic sorting process, reducing the overall sorting effect and recycling quality.

[0005] Therefore, developing a waste collection and sorting device that can achieve preliminary and efficient separation of metals and plastics and has further sorting functions is of great practical significance and has an urgent market demand for improving the efficiency of plastic waste recycling and treatment, increasing resource recycling rate, and reducing recycling costs.

[0006] Therefore, we propose an automatic waste collection and sorting device to solve the above problems. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] In view of the shortcomings of the prior art, the present invention provides an automatic waste collection and sorting device to solve the problems mentioned in the background art.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the present invention provides the following technical solution: an automatic waste collection and sorting device, comprising a main body, a main conveyor belt fixedly connected to the main body, gas generators fixedly connected symmetrically at equal intervals to the side wall of the main body, a sorting support plate fixedly connected to the inner side wall of the main body, and an inclined plate fixedly connected to one end of the sorting support plate near the main conveyor belt.

[0011] Preferably, a secondary conveyor belt is fixedly connected inside the sorting support plate, and a drop channel is formed between the inclined plate and the main conveyor belt, which is used for the metal to drop.

[0012] Preferably, a receiving box is fixedly connected to the bottom of the main body cavity, and the inner cavity of the receiving box is divided into gravity zone A, gravity zone B and gravity zone C.

[0013] Preferably, the main body has a first comb plate, a second comb plate, and a third comb plate fixedly connected at equal intervals on the side wall above the sorting support plate, and the first comb plate, the second comb plate, and the third comb plate are on the same horizontal line.

[0014] Preferably, a pusher is fixedly connected to the inner wall of the main body, and a transfer port is provided through the main body.

[0015] Preferably, the spacing between the first comb plate, the second comb plate, and the third comb plate is different.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an automatic waste collection and sorting device, which has the following beneficial effects:

[0018] 1. Through its overall design, this utility model offers the following advantages:

[0019] Significantly improved processing efficiency: This device uses weight to sort metals and plastics without human intervention. Compared to traditional manual sorting, it can process large quantities of plastic waste quickly and continuously, greatly shortening sorting time, effectively meeting the growing demand for waste treatment, and significantly improving the overall efficiency of plastic waste recycling.

[0020] Improving sorting accuracy and stability: Through precise weight parameter settings and an automated sorting mechanism, the device overcomes the drawbacks of manual sorting, which are affected by subjective factors and fatigue. Regardless of the complexity of the plastic waste composition, it can stably and accurately separate metals from plastics according to weight standards, effectively reducing metal loss, ensuring the integrity of resource recycling, and improving resource utilization. In addition, the stable sorting effect can also ensure the smooth progress of subsequent plastic sorting processes and improve the overall recycling quality.

[0021] 2. The design of the comb plate assembly consisting of the first comb plate, the second comb plate, and the third comb plate in this utility model can bring the following benefits to the overall operation:

[0022] Achieving refined sorting and improving the quality of resource recycling: The comb plate group consists of a first comb plate, a second comb plate, and a third comb plate. By rationally setting the gap and arrangement of each comb plate, it is possible to perform secondary sorting of the plastic parts after initial separation by size. The above-mentioned refined sorting mode can accurately distinguish plastic parts of different specifications and sizes, avoiding the situation of mixed processing during subsequent processing due to differences in the size of plastic parts. This significantly improves the purity and quality of plastic resource recycling, making the recycled plastic easier to process and utilize, and producing higher quality recycled plastic products.

[0023] Reducing subsequent processing costs and improving economic efficiency: After sorting plastic parts by size using a comb assembly, different specifications of plastic parts can be processed using targeted subsequent processes based on their characteristics. For example, smaller plastic parts may be more suitable for direct melt-granulation, while larger plastic parts can be crushed first. This precise sorting and processing method avoids energy waste and equipment wear caused by indiscriminate processing, reduces energy costs and equipment maintenance costs in subsequent processing, thereby improving the economic efficiency of enterprises and enhancing the profitability of recycling companies in the market.

[0024] 3. This utility model, through its sorting design based on the weight characteristics of metals and the laws of free fall, brings the following benefits to the overall operation:

[0025] Simplifying equipment structure and reducing manufacturing costs: This design relies solely on the weight characteristics of the metal itself and the laws of free fall to achieve sorting, eliminating the need for additional auxiliary components such as magnetic separation and eddy current separation, which greatly simplifies the overall structure of the equipment. This not only reduces the cost of parts procurement, processing and assembly, but also reduces the design complexity of the equipment, shortens the R&D and production cycle, and saves enterprises a lot of upfront investment.

[0026] Improved operational stability and reduced maintenance costs: By eliminating complex auxiliary components, the number of potential failure points of the equipment is significantly reduced, avoiding downtime caused by aging auxiliary components, circuit failures, or mechanical wear. At the same time, the simplified structure makes daily maintenance more convenient, eliminating the need for professional personnel to regularly inspect precision auxiliary components, reducing the labor and time costs of maintenance, extending the continuous operating time of the equipment, and ensuring the stability of the sorting process.

[0027] Enhanced sorting versatility and adaptability to diverse metals: This design sorts metals based on their weight differences, unaffected by other physical properties such as magnetism or conductivity. Whether it's common metals like iron and aluminum, or other materials like copper and zinc, as long as there's a weight difference, effective separation can be achieved through the different trajectories of free fall. This greatly expands the equipment's adaptability to metal waste, making it particularly suitable for sorting waste containing a mixture of various non-magnetic or weakly magnetic metals.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0037] Example

[0038] Please refer to Figures 1 to 5 As shown:

[0039] An automatic waste collection and sorting device includes a main body 1, a main conveyor belt 2 fixedly connected to the main body 1, gas generators 3 symmetrically fixedly connected at equal intervals to the side walls of the main body 1, a sorting support plate 4 fixedly connected to the inner side wall of the main body 1, an inclined plate 5 fixedly connected to one end of the sorting support plate 4 near the main conveyor belt 2, a secondary conveyor belt 6 fixedly connected inside the sorting support plate 4, and a drop channel 7 formed by the gap between the inclined plate 5 and the main conveyor belt 2 for the dropping of metal. A receiving box 8 is fixedly connected to the bottom of the inner cavity of the main body 1. The inner cavity of the receiving box 8 is divided into gravity zone A 81, gravity zone B 82, and gravity zone C 83. A first comb plate 9, a second comb plate 10, and a third comb plate 11 are fixedly connected at equal intervals on the side wall of the main body 1 and above the sorting support plate 4. The first comb plate 9, the second comb plate 10, and the third comb plate 11 are on the same horizontal line. A pushing member 12 is fixedly connected to the inner wall of the main body 1. A transfer port 13 is opened through the main body 1.

[0040] in:

[0041] This device performs initial sorting of metal and plastic parts, and then performs secondary sorting of plastic parts that can be recycled.

[0042] The main conveyor belt 2 is used to transport crushed plastic parts containing metal.

[0043] The gas generator 3 blows the plastic parts on the main conveyor belt 2 at an angle, and the plastic parts, which are lighter than metal, are blown onto the secondary conveyor belt 6.

[0044] In addition to assisting in the transfer of plastic parts onto the secondary conveyor belt 6, the inclined plate 5 can also be used on its inner surface to guide the movement of metal parts.

[0045] Different metals, such as iron and aluminum, are conveyed by the main conveyor belt 2. Under the premise that the weights of different metals are different, when the initial conveying speed of the main conveyor belt 2 is the same, the heavier metal will fall into gravity zone A 81, and the lighter metal will fall into gravity zone B 82 or gravity zone C 83.

[0046] Gravity Zone A (81), Gravity Zone B (82), and Gravity Zone C (83) are used to support metals of different weights.

[0047] The different spacing between the first comb plate 9, the second comb plate 10, and the third comb plate 11 is used to perform secondary sorting of the plastic parts on the secondary conveyor belt 6 according to their size.

[0048] The pusher 12 can push the plastic parts on the secondary conveyor belt 6 and transfer their position through the transfer port 13.

[0049] Working principle:

[0050] During use, metal and plastic parts are conveyed by the main conveyor belt 2. During the conveying process, when the metal and plastic parts move to the area blown by the gas generator 3, the plastic parts, being lighter, will be blown by the airflow through the inclined plate 5 onto the secondary conveyor belt 6 set on the sorting support plate 4. Furthermore, as the secondary conveyor belt 6 conveys the plastic parts, the spacing design of the first comb plate 9, the second comb plate 10, and the third comb plate 11 will divide the plastic parts into different sizes, and then they will be transferred from the transfer port 13 to the receiving container of the external device by the pushing of the pushing component 12.

[0051] Furthermore, when the main conveyor belt 2 transports different metals, due to the weight characteristics of the unit metal under the law of free fall, different metals will fall into different chambers in the receiving box 8. Specifically, heavier metals will fall into gravity zone A 81, while lighter metals will fall into gravity zone B 82 or gravity zone C 83; thus, different metals are sorted.

[0052] Please refer to the above work process. Figures 1 to 5 .
