Description

Technical Field

[0001] The invention relates to the technical field of sponge waste recycling, in particular to a sponge waste recycling and processing device and a processing method. Background Art

[0002] Sponge waste mainly refers to polyurethane sponge waste, including sponge fillings from furniture disassembly, industrial scraps, and daily cleaning sponges; sponges are dry garbage, and their main component is polyurethane, which has high chemical stability and is difficult to degrade naturally. Random landfill will occupy space for a long time and pollute the environment.

[0003] Current mainstream treatment methods include physical recycling (crushing, compacting, and reducing the volume by 80% to create recycled filler materials), chemical recycling (bioacid / enzymatic hydrolysis to extract polyols, with a recovery rate exceeding 95%), and high-value recycling (such as modification into magnetic oil-absorbing sponges or antibacterial functional materials). Through specialized recycling technologies, sponge waste can be converted into industrial raw materials such as sound insulation and insulation boards, achieving resource recycling and carbon reduction (recycled PU reduces its carbon footprint by 88%), making it a key component of building "zero-waste cities."

[0004] During the sponge recycling process, sponge waste is difficult to enter the crushing mechanism due to its light material. Some existing technologies (such as the patent for a waste sponge recycling device, application number 202411006633.3) use humidification and weighting to improve the efficiency of sponge waste entering the crushing mechanism. This involves spraying water evenly onto the sponge surface through a spray system to increase its weight and density, preventing the lightweight sponge from bouncing or idling during crushing. However, the increased weight of the sponge waste increases the workload of the crushing mechanism during the crushing process, increasing energy consumption. Furthermore, the water absorbed into the sponge needs to be separated, which also increases work consumption. Summary of the Invention

[0020] In the embodiment of the present invention, please refer to Figure 1-Figure 5 : A sponge waste recycling and processing device includes a feed trough 100 for storing sponge waste and a recycling and processing base 200 for recycling and processing sponge waste, wherein the recycling and processing base 200 is installed at the bottom of the feed trough 100 and is connected to the feed trough 100; During the recycling of the sponge waste, the sponge waste is placed into the feed trough 100 and driven by a feed auger installed at the connection between the feed trough 100 and the recycling base 200, and is introduced into the recycling base 200; the feed auger is a prior art, which can be purchased directly on the market, or can be found in existing literature and journals, or directly found on the website, and is well known to those skilled in the art or can be easily obtained; The recycling base 200 includes two support platforms 300 and a plurality of unit recovery tanks 400 mounted on the two support platforms 300. The two support platforms 300 are arranged in parallel, and the plurality of unit recovery tanks 400 are distributed at equal intervals along the two support platforms 300. The unit recovery tanks 400 are connected to the feed trough 100. The sponge waste in the feed trough 100 is respectively conveyed into the multiple unit recovery tanks 400 by the conveying screws corresponding to the multiple unit recovery tanks 400. The unit recovery tanks 400 are used to crush the sponge waste, which is conducive to subsequent recycling. The unit recovery tank 400 is internally provided with two sponge waste recovery racks 600, which are symmetrically distributed at both ends of the unit recovery tank 400; a sponge waste recovery chamber 500 is formed between the two sponge waste recovery racks 600 within the unit recovery tank 400; The sponge waste that enters the unit recovery tank 400 will fall into the sponge waste recovery chamber 500 between the two sponge waste recovery racks 600. Thereafter, the sponge waste can be crushed using the sponge waste recovery racks 600, which is beneficial for subsequent recycling. The sponge waste recovery rack 600 includes an adjustment rack 610, which is mounted at the end of the unit recovery tank 400. The adjustment rack 610 adjusts the size of the sponge waste recovery chamber 500 by telescopic adjustment. The sponge waste recovery rack 600 also includes a crushing assembly 620, which is mounted on the adjustment rack 610 and is triggered by the adjustment rack 610 to crush the sponge waste. The sponge waste that falls into the sponge waste recovery chamber 500 between the two sponge waste recovery racks 600 is stretched and squeezed toward each other by the adjustment racks 610 on the two sponge waste recovery racks 600, thereby completing the adjustment of the size of the sponge waste recovery chamber 500 while shaping and squeezing the sponge waste, thereby compressing the sponge waste in a fixed space; the adjustment rack 610 then drives the crushing assembly 620 in this fixed space to efficiently crush the shaped and compacted sponge waste.

[0021] In the embodiment of the present invention, the sponge waste is put into the feed trough 100 and is driven by a conveying screw installed at the connection between the feed trough 100 and the recycling and processing base 200, so that the sponge waste inside the feed trough 100 is then driven into the multiple unit recovery tanks 400 by the conveying screws corresponding to the multiple unit recovery tanks 400; the sponge waste entering the unit recovery tank 400 will fall into the sponge waste recovery cavity 500 between the two sponge waste recovery racks 600, and will be stretched and squeezed toward each other by the adjustment racks 610 on the two sponge waste recovery racks 600, completing the adjustment of the size of the sponge waste recovery cavity 500 while shaping and squeezing the sponge waste, so as to compress the sponge waste in a fixed space; the adjustment rack 610 then drives the crushing assembly 620 in this fixed space to efficiently crush the shaped and compacted sponge waste; it can easily cope with sponge waste with lighter materials and avoid excessive energy consumption caused by weight gain.

[0022] That is, this application can achieve the following compared to the prior art: Sponge waste enters through the feed chute 100 and is precisely distributed to multiple unit recovery tanks 400 via a conveying auger. After the waste falls into the sponge waste recovery chamber 500 formed by the dual adjustment frames 610, the adjustment frames 610 extend and retract toward each other to complete a dual action, enabling dynamic chamber control, pre-compression shaping, and in-situ crushing. Dynamic chamber control compresses the chamber space to a fixed volume in real time, pre-compression shaping forcibly squeezes lightweight sponge into high-density blocks, and in-situ crushing involves the crushing assembly 620 directly cutting within the compressed space to prevent material scattering. Solving industry pain points, mechanical pre-compression replaces traditional spray weighting to reduce energy consumption, and closed crushing suppresses the risk of PU dust explosions. The adjustment frame 610 cooperates with the pressure sensor to provide real-time feedback on the sponge hardness (such as 10-30kPa for soft PU and 50-100kPa for hard PU), automatically matching the cavity compression ratio to achieve differentiated compression and directional recovery, improving the high-value recovery rate and avoiding performance degradation caused by mixed processing.

During this process, the limit plates 6102 on the two adjustment frames 610 move seamlessly along the space inside the unit recovery tank 400, completing the adjustment of the size of the sponge waste recovery chamber 500 while shaping and squeezing the sponge waste, so that the sponge waste is compressed and compacted in a fixed space; then start multiple telescopic rods A6101 for periodic expansion and contraction, so that multiple telescopic rods A6101 drive the crushing assembly 620 in this fixed space to efficiently crush the shaped and compacted sponge waste.
