Description

Technical Field

[0001] This utility model relates to the field of waste sorting, recycling and treatment technology, and in particular to a system for the co-recycling and treatment of large furniture waste and low-value recyclables. Background Technology

[0002] Bulky furniture waste refers to low-value furniture waste that weighs more than 5 kg, has a volume exceeding 0.2 cubic meters, or a length exceeding 1 meter, and is highly structurally sound, requiring dismantling. This includes used mattresses, sofas, and tables and chairs. Currently, bulky furniture waste accounts for a relatively small proportion of household waste, and most existing bulky furniture waste processing lines operate for less than 2 hours per day, resulting in idle equipment.

[0003] Low-value recyclables constitute a significant portion of household waste. These mainly consist of recyclables that can be disposed of in the blue recycling bins, including plastic lunch boxes, plastic cups, foam blocks, Tetra Pak cartons, paper cups and bowls, instant noodle bowls, soy milk cups, courier bags, courier packing materials, and plastic bags. However, due to their low value, wide variety, and difficulty in sorting, low-value recyclables are often disposed of as other waste in the yellow recycling bins, ending up in incineration plants or landfills, failing to achieve resource utilization.

[0004] Therefore, the inventors hope to develop a system for the co-processing of bulky furniture waste and low-value recyclables, which can not only improve the equipment utilization rate of bulky furniture waste processing lines, but also realize the resource utilization of low-value recyclables. Utility Model Content

[0005] The purpose of this invention is to provide a system for the collaborative recycling and processing of bulky furniture waste and low-value recyclables, which solves the problems existing in the prior art. It can improve the equipment utilization rate of bulky furniture waste processing lines and realize the resource utilization of low-value recyclables.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A system for the co-recycling and processing of bulky furniture waste and low-value recyclables is disclosed. The bulky furniture waste is first screened by a spring mattress identification device, with spring mattresses being diverted to a spring mattress dismantling device, while other bulky furniture waste is diverted to a bulky waste shredder. The dismantled material from the spring mattress dismantling device is then conveyed to the spring shredder to separate the springs, while other materials are conveyed to the bulky waste shredder. The shredded material from the bulky waste shredder is then conveyed to a magnetic separator, and the low-value recyclables are pre-treated by a leveling machine and a bag-breaking machine before being conveyed to the magnetic separator. The magnetic separator separates magnetic metal materials, while the remaining materials are conveyed to the drum screen. The drum screen is used to separate materials with a particle size of 300mm or more and 300mm or less. Materials with a particle size of 300mm or more are conveyed to the manual sorting station, while materials with a particle size of 300mm or less are conveyed to the bouncing screen. The manual sorting station classifies the materials and returns large pieces of waste that need to be crushed to the large waste crusher, and screens out two-dimensional plastic recyclables which are conveyed to the photoelectric separator. The bouncing screen is used to screen plastics which are conveyed to the photoelectric separator, and to convey wood to the wood sorter.

[0008] The wood separated by the wood sorting machine is then processed into RDF particles by a crusher, a dryer, and an RDF particle compressor.

[0009] After adopting the above technical solution, the present invention has the following technical effects:

[0010] This invention enables the co-processing of bulky furniture waste and low-value recyclables, improves the utilization rate of bulky furniture waste processing equipment, reduces the number of equipment and capital investment required for processing low-value recyclables, and achieves refined classification of low-value recyclables for subsequent resource utilization.

Detailed Implementation

[0014] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0015] refer to Figure 1As shown, this utility model discloses a system for the co-recycling and processing of bulky furniture waste and low-value recyclables. After passing through a spring mattress identification device 1, the bulky furniture waste is sorted out by spring mattresses and diverted to a spring mattress dismantling device 2. Other bulky furniture waste is diverted to a bulky waste shredder 3. The material after dismantling by the spring mattress dismantling device 2 is conveyed to a spring shredder 4 to separate the springs. Other materials (generally including fabric, latex, and coconut fiber) are conveyed to the bulky waste shredder 3. The material after shredding by the bulky waste shredder 3 is conveyed to a magnetic separator 5. Low-value recyclables are pre-treated by a material leveler 6 and a bag-breaking machine 7 before being conveyed to the bulky waste shredder 3. The magnetic separator 5 separates magnetic metal materials for sale to downstream enterprises for reuse, while the remaining materials are conveyed to the drum screen 8. The drum screen 8 is used to screen materials with a particle size of 300mm or more and materials with a particle size of less than 300mm. Materials with a particle size of more than 300mm are conveyed to the manual sorting station 9, and materials with a particle size of less than 300mm are conveyed to the bouncing screen 10. The manual sorting station 9 classifies the materials and returns the large pieces of waste that need to be crushed to the large pieces of waste crusher 3, and screens out two-dimensional plastic recyclables which are conveyed to the photoelectric separator 11. The bouncing screen 10 is used to screen plastics which are conveyed to the photoelectric separator 11, and wood which is conveyed to the wood sorting machine 12.

[0016] Through the above solution, this utility model can achieve the co-processing of large furniture waste and low-value recyclables, improve the utilization rate of large furniture waste processing equipment, reduce the number of equipment and capital investment for processing low-value recyclables, and achieve refined classification of low-value recyclables for subsequent resource utilization.

[0017] The following are specific embodiments of the present invention.

[0018] The spring crusher 4 mentioned above is a fine-particle crusher, which can crush springs into lengths of 2-5cm; the large-item waste crusher 3 is a coarse-particle crusher, which can crush large-item waste into materials smaller than 300mm, including metal, cloth, latex, coconut fiber, wood, etc.

[0019] Materials with a particle size of 300mm or larger, separated by the drum screen (8), are mainly large-volume foam plastics, corrugated cardboard, plastic bags, etc., while materials with a particle size of less than 300mm include Tetra Pak cartons, plastic bottles, wood, etc.

[0020] In the aforementioned manual sorting station 9, waste paper such as foam plastics and corrugated paper, other waste and two-dimensional plastic recyclables (soft materials) are manually sorted out. The two-dimensional plastic recyclables are then sent to the subsequent photoelectric sorting machine 11 for further classification.

[0021] The aforementioned bouncing screen 10 mainly separates heavier wood and finer materials and conveys them to the wood sorting machine 12, while other lighter recyclable plastic materials, such as Tetra Pak cartons, enter the photoelectric sorting machine 11.

[0022] The wood screened by the aforementioned bouncing screen 10 may contain coconut fiber, sponge, etc. Therefore, after passing through the wood sorting machine 12, the wood can be separated from other impurities and then passed through the crusher 13, dryer 14, and RDF pellet compressor 15 in sequence to make RDF pellets, which can be used as fuel. The separated sponge material can be used for downstream production of cushions, seat cushions, etc., and the coconut fiber material can be used as filling material for carpet production, etc. The remaining materials are sent to the incineration plant for disposal.

[0023] The aforementioned photoelectric sorting machine 11 can separate PET plastic, PP plastic, PE plastic, Tetra Pak cartons and other recyclable materials.

[0024] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
