Description

Technical Field

[0001] This invention relates to the field of sponge waste recycling technology, specifically to a sponge waste recycling and processing device and method. Background Technology

[0002] Sponge waste mainly refers to polyurethane sponge waste, including sponge fillings from dismantled furniture, industrial scraps, and daily cleaning sponges. Sponges are classified as dry waste, with polyurethane as their main component. They have high chemical stability and are difficult to degrade naturally. Indiscriminate landfilling will occupy space and pollute the environment for a long time.

[0003] Currently, the mainstream processing methods include: physical recycling (crushing and compacting to reduce volume by 80% to produce recycled filler materials), chemical recycling (biological acid hydrolysis / enzymatic hydrolysis to extract polyols, with a recovery rate of over 95%), and high-value recycling (such as modification into magnetic oil-absorbing sponges or antibacterial functional materials). Through specialized recycling technologies, waste sponges can be transformed into industrial raw materials such as sound insulation cotton and thermal insulation boards, achieving resource recycling and carbon emission reduction (recycled PU reduces the carbon footprint by 88%), which is a key link in the construction of "zero-waste cities".

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

[0005] In the process of recycling and crushing waste sponge, due to the lightweight nature of sponge, it is difficult for waste sponge to enter the crushing mechanism. Some existing technologies use humidification to increase the weight and improve the efficiency of the waste sponge entering the crushing mechanism. However, the increased weight of the waste sponge increases the workload of the crushing mechanism during crushing, thus increasing energy consumption. Furthermore, the water absorbed into the sponge needs to be separated, which also increases workload. To achieve the above objectives, this invention provides the following technical solution:

[0006] A sponge waste recycling and processing device includes a feeding trough for storing sponge waste and a recycling and processing base for recycling and processing the sponge waste. The recycling and processing base is installed at the bottom of the feeding trough and communicates with it. The recycling and processing base includes two support platforms and multiple unit recycling tanks mounted on the two support platforms. The two support platforms are parallel to each other, and the multiple unit recycling tanks are evenly spaced along the two support platforms. The unit recycling tanks are communicated with the feeding trough. Each unit recycling tank has two sponge waste recycling racks installed inside it. The two sponge waste recycling racks are distributed at both ends of the unit recycling tank and are symmetrically arranged. A sponge waste recycling cavity is formed between the two sponge waste recycling racks inside the unit recycling tank. Each sponge waste recycling rack includes an adjusting frame installed at the end inside the unit recycling tank. The adjusting frame can be extended or retracted to adjust the size of the sponge waste recycling cavity. The sponge waste recycling rack also includes a crusher. The component, a crushing assembly mounted on an adjusting frame, is triggered by the adjusting frame to crush sponge waste. The sponge waste is placed into the feeding trough and driven by a conveyor auger installed at the connection between the feeding trough and the recycling base. The sponge waste inside the feeding trough is then conveyed into multiple unit recycling tanks by conveyor augers corresponding to each unit. The sponge waste entering the unit recycling tank falls into the sponge waste recycling chamber between two sponge waste recycling racks. There, it is compressed and squeezed by the adjusting frames on the two racks, adjusting the size of the recycling chamber while simultaneously shaping and compressing the sponge waste into a fixed space. The adjusting frame then drives the crushing assembly within this fixed space to efficiently crush the compressed sponge waste. This method can easily handle lighter sponge waste, avoiding excessive energy consumption due to added weight.

[0007] The optimized unit recycling tank includes a recycling tank body, on which an inlet pipe and an outlet pipe are installed, both of which are connected to the recycling tank body; a control valve is installed on both the inlet pipe and the outlet pipe; a sealing plate is detachably installed at each end of the recycling tank body, and an adjusting frame is installed on the sealing plate.

[0008] The optimized adjustment frame includes a telescopic rod B and multiple telescopic rods A. One end of the telescopic rod B is equipped with an installation plate, and the other end is equipped with a limiting plate. The limiting plate matches the internal dimensions of the unit recycling tank and can move seamlessly along the internal space of the unit recycling tank. Multiple telescopic rods A are arranged in a circular array on the limiting plate, and the end of the telescopic rod A away from the limiting plate is installed on the crushing assembly.

[0009] Optimized, the telescopic rod A and telescopic rod B include electric telescopic rods, hydraulic telescopic rods, and pneumatic telescopic rods.

[0010] The optimized crushing assembly includes a fixed cutting mesh structure and a movable cutting mesh structure. The fixed cutting mesh structure is assembled on the ends of multiple telescopic rods A and is used to adjust the distance between the crushing assembly and the limiting plate when the multiple telescopic rods A extend and retract synchronously. The movable cutting mesh structure is rotatably assembled on the fixed cutting mesh structure and is driven to rotate by a power device installed on the fixed cutting mesh structure.

[0011] The optimized fixed cutting mesh structure includes an outer limiting ring and a fixed cutting mesh, with the fixed cutting mesh fixed inside the outer limiting ring. The column center lines of the outer limiting ring and the fixed cutting mesh are on the same straight line.

[0012] In the optimized configuration, a positioning disc is provided on the column centerline of the fixed cutting mesh, and a rotating shaft is rotatably inserted on the positioning disc. One end of the rotating shaft is fixed to the movable cutting mesh structure, and the other end is connected to the power device via power transmission. The power device includes a drive motor, and the rotating shaft is fixed on the output shaft of the drive motor.

[0013] The optimized movable cutting mesh structure includes a fixed ring, with a bearing ring on the outside of the fixed ring. The fixed ring is rotatably mounted on the outer limiting ring via the bearing ring. The movable cutting mesh is fixed inside the fixed ring and is movably attached to the fixed cutting mesh.

[0014] In an optimized configuration, the fixed cutting mesh and the movable cutting mesh adopt the same structure, with the fixed cutting mesh consisting of multiple crisscrossing cutting plates.

[0015] The optimized design includes a feeding chamber and a discharging chamber inside the cutting plate, and cavities A and B inside the positioning plate. The feeding chamber is connected to cavity A, and the discharging chamber is connected to cavity B. A ducted air hose is inserted through the limiting plate, with one end connected to the positioning plate. The ducted air hose is divided into a guiding chamber A and a guiding chamber B inside, with guiding chamber A connected to cavity A and guiding chamber B connected to cavity B. The other end of the ducted air hose is connected to a cooler, which is equipped with a water pump and a cooling plate.

[0016] Another object of the present invention is to provide a processing method for the sponge waste recycling and processing device described above, comprising the following steps:

[0017] Step 1: Intelligent Diversion Tank

[0018] The waste sponge material in the feed trough is conveyed to the distribution hub by the conveying auger. The material density is identified by the pressure sensor and automatically distributed to the corresponding unit recycling tank.

[0019] Step 2: Dynamic compression molding

[0020] The dual-adjustment frame coordinates the control of the sponge waste recycling chamber.

[0021] S1. The telescopic rod B drives the limiting plate to move seamlessly along the tank wall, compressing the sponge waste recycling chamber to the target volume;

[0022] S2. The pressure feedback system adjusts the compression force in real time to form a fixed spatial block with a density of not less than 150 kg / m³.

[0023] Step 3: In-situ multi-stage grinding

[0024] Telescopic rod A drives the cutting plates on the fixed and movable cutting mesh to move crosswise, dividing the compressed block into 50 mm³ fragments, completing the primary crushing by the longitudinal and transverse cutting plates; the drive motor drives the movable cutting mesh to rotate relative to the fixed cutting mesh; the cooler pumps cooling water sequentially through the guide chamber A, the feed chamber, the through chamber B, and the guide chamber B to circulate and cool the material, ensuring that the crushing temperature does not exceed 60℃; thus completing the deep crushing by the rotating cutting mesh.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] Sponge waste is placed into the feeding trough 100 and driven by a conveying auger installed at the connection between the feeding trough 100 and the recycling base 200. The sponge waste inside the feeding trough 100 is then carried into the multiple unit recycling tanks 400 by conveying augers corresponding to each unit recycling tank 400. The sponge waste entering the unit recycling tank 400 falls into the sponge waste recycling cavity 500 between two sponge waste recycling racks 600. There, the adjusting racks 610 on the two sponge waste recycling racks 600 extend and squeeze towards each other, adjusting the size of the sponge waste recycling cavity 500 while shaping and compressing the sponge waste into a fixed space. The adjusting racks 610 then drive the crushing component 620 in this fixed space to efficiently crush the shaped and compressed sponge waste. This method can easily handle lighter sponge waste, avoiding excessive energy consumption due to weight gain.

[0027] Sponge waste enters through the feed chute 100 and is precisely distributed to multiple unit recycling tanks 400 via a conveyor auger. After the waste falls into the sponge waste recycling chamber 500 composed of double adjusting frames 610, the adjusting frames 610 extend and retract in opposite directions to complete a dual action, which can realize dynamic chamber control, pre-compression molding, and in-situ crushing. Dynamic chamber control is to compress the chamber space to a fixed volume in real time. Pre-compression molding is to forcibly compress the lightweight sponge into a high-density block. In-situ crushing is to directly cut the material within the compression space by the crushing component 620, avoiding material scattering. This solves industry pain points, with mechanical pre-compression replacing the traditional spraying method that increases weight and reduces energy consumption. The closed crushing method suppresses the risk of PU dust explosion.

[0028] The 610 adjustment frame, in conjunction with a pressure sensor, provides real-time feedback on the sponge hardness and automatically matches the chamber compression ratio to achieve fractional compression and directional recycling, thereby improving the high-value recycling rate and avoiding performance degradation caused by mixed processing.

[0029] During the relative rotation between the movable cutting mesh 6223 and the fixed cutting mesh 6212, the cooler can use a water pump to draw cooling water into the material guide chamber A of the air guide hose 6103, and then into the feed chamber of the cutting plate through the chamber A, to cool down the fixed cutting mesh 6212 and the movable cutting mesh 6223, so as to avoid the friction heat generated by the cutting of sponge waste during the cutting process, which would affect the sponge and be detrimental to recycling.

[0044] The technical solution of the present invention will be further described in detail below with reference to specific embodiments. In the description of the present invention, unless otherwise stated, "a plurality of" means two or more.

[0045] In the embodiments of this invention, please refer to Figures 1-5 A sponge waste recycling and processing device includes a feeding trough 100 for storing sponge waste and a recycling and processing base 200 for recycling and processing sponge waste. The recycling and processing base 200 is installed at the bottom of the feeding trough 100 and is in communication with the feeding trough 100.

[0046] During the recycling and processing of sponge waste, the sponge waste is placed into the feed trough 100 and driven by the conveying auger installed at the connection between the feed trough 100 and the recycling base 200, and guided into the recycling base 200. At the same time, the conveying auger is existing technology, which can be purchased directly on the market, or can be found in existing literature and journals, or can be found directly on the website. It is well known to those skilled in the art, or can be easily obtained.

[0047] The recycling base 200 includes two support platforms 300 and multiple unit recycling tanks 400 mounted on the two support platforms 300. The two support platforms 300 are arranged in parallel, and the multiple unit recycling tanks 400 are arranged at equal intervals along the two support platforms 300. The unit recycling tanks 400 are connected to the feed trough 100.

[0048] The sponge waste inside the feed trough 100 is carried into the multiple unit recycling tanks 400 by conveying augers that correspond one-to-one with the multiple unit recycling tanks 400. The unit recycling tanks 400 are used to crush the sponge waste, which is beneficial for subsequent recycling.

[0049] The unit recycling tank 400 is equipped with two sponge waste recycling racks 600 inside. The two sponge waste recycling racks 600 are distributed at both ends inside the unit recycling tank 400 and are symmetrically distributed. A sponge waste recycling cavity 500 is formed between the two sponge waste recycling racks 600 inside the unit recycling tank 400.

[0050] The sponge waste that enters the unit recycling tank 400 will fall into the sponge waste recycling chamber 500 between the two sponge waste recycling racks 600. After that, the sponge waste can be crushed by the sponge waste recycling rack 600, which is beneficial for subsequent recycling.

[0051] The sponge waste recycling rack 600 includes an adjusting rack 610, which is installed at the end inside the unit recycling tank 400. The adjusting rack 610 can adjust the size of the sponge waste recycling chamber 500 by telescopic adjustment. The sponge waste recycling rack 600 also includes a crushing component 620, which is installed on the adjusting rack 610. The crushing component 620 is triggered by the adjusting rack 610 to crush and process the sponge waste.

[0052] The sponge waste falling into the sponge waste recycling chamber 500 between the two sponge waste recycling racks 600 is stretched and squeezed by the adjusting racks 610 on the two sponge waste recycling racks 600 towards each other. This adjusts the size of the sponge waste recycling chamber 500 while shaping and squeezing the sponge waste, thus compressing the sponge waste into a fixed space. The adjusting racks 610 then drive the crushing component 620 to efficiently crush the shaped and compressed sponge waste in this fixed space.

[0053] In this embodiment of the invention, waste sponge is placed into the feeding trough 100 and driven by a conveying auger installed at the connection between the feeding trough 100 and the recycling base 200. The waste sponge inside the feeding trough 100 is then conveyed into the multiple unit recycling tanks 400 by conveying augers corresponding to each unit recycling tank 400. The waste sponge inside the unit recycling tank 400 falls into the waste sponge recycling cavity 500 between two waste sponge recycling racks 600. It is then squeezed by the adjusting racks 610 on the two waste sponge recycling racks 600, which simultaneously adjust the size of the waste sponge recycling cavity 500 and shape and compress the waste sponge into a fixed space. The adjusting racks 610 then drive the crushing component 620 in this fixed space to efficiently crush the shaped and compressed waste sponge. This method can easily handle lightweight waste sponge and avoids excessive energy consumption due to weight gain.

[0054] In other words, this application can achieve the following compared to the prior art:

[0055] Sponge waste enters through the feed chute 100 and is precisely distributed to multiple unit recycling tanks 400 via a conveyor auger. After the waste falls into the sponge waste recycling chamber 500 composed of double adjusting frames 610, the adjusting frames 610 extend and retract in opposite directions to complete a dual action, which can realize dynamic chamber control, pre-compression molding, and in-situ crushing. Dynamic chamber control is to compress the chamber space to a fixed volume in real time. Pre-compression molding is to forcibly compress the lightweight sponge into a high-density block. In-situ crushing is to directly cut the material within the compression space by the crushing component 620, avoiding material scattering. This solves industry pain points, with mechanical pre-compression replacing the traditional spraying method that increases weight and reduces energy consumption. The closed crushing method suppresses the risk of PU dust explosion.

[0056] The adjustment frame 610, in conjunction with a pressure sensor, provides real-time feedback on the sponge hardness (e.g., soft PU 10–30 kPa, hard PU 50–100 kPa), automatically matching the chamber compression ratio to achieve fractional compression and directional recycling, improving the high-value recycling rate and avoiding performance degradation caused by mixed processing.

[0057] In the embodiments of this invention, please refer to Figure 3 and Figure 4 The unit recycling tank 400 includes a recycling tank body 410, on which an inlet pipe 420 and an outlet pipe are installed, both of which are connected to the recycling tank body 410; control valves are installed on both the inlet pipe 420 and the outlet pipe; a sealing plate 430 is detachably installed at each end of the recycling tank body 410, and an adjusting frame 610 is installed on the sealing plate 430.

[0058] In the embodiments of this invention, please refer to Figures 4-6 The adjusting frame 610 includes a telescopic rod B6104 and multiple telescopic rods A6101. One end of the telescopic rod B6104 is equipped with an installation plate 6105 (specifically, the installation plate 6105 is installed on the sealing plate 430), and the other end is equipped with a limit plate 6102.

[0059] The limiting plate 6102 is matched with the internal dimensions of the unit recycling tank 400, and the limiting plate 6102 can move seamlessly along the internal space of the unit recycling tank 400; multiple telescopic rods A6101 are arranged in a ring array on the limiting plate 6102, and the end of the telescopic rod A6101 away from the limiting plate 6102 is installed on the crushing assembly 620.

[0060] The sponge waste entering the unit recycling tank 400 will fall into the sponge waste recycling chamber 500. The telescopic rod B6104 on the adjusting frame 610 is activated, so that the adjusting frames 610 on the two sponge waste recycling frames 600 extend towards each other. During this process, the limiting plate 6102 on the two adjusting frames 610 moves seamlessly along the space inside the unit recycling tank 400, adjusting the size of the sponge waste recycling chamber 500 while shaping and squeezing the sponge waste, so as to compress the sponge waste into a fixed space. Then, multiple telescopic rods A6101 are activated to periodically extend and retract, so that multiple telescopic rods A6101 drive the crushing component 620 in this fixed space to efficiently crush the shaped and compressed sponge waste.

[0061] The telescopic rods A6101 and B6104 include electric telescopic rods, hydraulic telescopic rods, and pneumatic telescopic rods.

[0062] In the embodiments of this invention, please refer to Figures 5-9 The crushing assembly 620 includes a fixed cutting mesh structure 621 and a movable cutting mesh structure 622. The fixed cutting mesh structure 621 is assembled on the ends of multiple telescopic rods A6101 and is used to adjust the distance between the crushing assembly 620 and the limiting disk 6102 when the multiple telescopic rods A6101 extend and retract synchronously.

[0063] The movable cutting mesh structure 622 is rotatably mounted on the fixed cutting mesh structure 621 and is driven to rotate by a power device installed on the fixed cutting mesh structure 621.

[0064] In the embodiments of this invention, please refer to Figure 10 and Figure 11 The fixed cutting mesh structure 621 includes an outer limiting ring 6211 and a fixed cutting mesh 6212. The fixed cutting mesh 6212 is fixed inside the outer limiting ring 6211, and the column center lines of the outer limiting ring 6211 and the fixed cutting mesh 6212 are on the same straight line.

[0065] Please see Figure 10 and Figure 11 A positioning disk 6214 is provided on the column center line of the fixed cutting mesh 6212. A rotating shaft 6213 is rotatably inserted on the positioning disk 6214. One end of the rotating shaft 6213 is fixed on the movable cutting mesh structure 622, and the other end is connected to the power device for power transmission.

[0066] The power unit includes a drive motor 6215, and a rotating shaft 6213 is fixed on the output shaft of the drive motor 6215.

[0067] Please see Figure 9 and Figure 12The movable cutting mesh structure 622 includes a fixing ring 6222, and a bearing ring 6221 is provided on the outside of the fixing ring 6222. The fixing ring 6222 is rotatably assembled on the outer limiting ring 6211 through the bearing ring 6221.

[0068] The fixed ring 6222 has a movable cutting mesh 6223 fixed inside, and the movable cutting mesh 6223 is movably attached to the fixed cutting mesh 6212.

[0069] Please see Figure 10 and Figure 12 The fixed cutting mesh 6212 and the movable cutting mesh 6223 adopt the same structure. The fixed cutting mesh 6212 is composed of multiple crisscrossing cutting plates.

[0070] Multiple telescopic rods A6101 drive the crushing assembly 620 in this fixed space, using multiple crisscrossing cutting plates to efficiently crush the molded and compressed sponge waste. During this process, the drive motor 6215 is activated, and the drive motor 6215 drives the movable cutting mesh 6223 to rotate relative to the fixed cutting mesh 6212 through the rotating shaft 6213, further efficiently crushing the sponge waste.

[0071] Please see Figure 6 , Figure 10 and Figure 12 The cutting plate has an infeed chamber and an outlet chamber inside. The positioning plate 6214 has a cavity A and a cavity B inside. The infeed chamber is connected to cavity A, and the outlet chamber is connected to cavity B. A gas guide hose 6103 is inserted through the limiting plate 6102. One end of the gas guide hose 6103 is connected to the positioning plate 6214. The gas guide hose 6103 is divided into a guide chamber A and a guide chamber B inside. Guide chamber A is connected to cavity A, and guide chamber B is connected to cavity B. The other end of the gas guide hose 6103 is connected to the cooler. The cooler is equipped with a water pump and a cooling plate.

[0072] During the relative rotation between the movable cutting mesh 6223 and the fixed cutting mesh 6212, the cooler can use a water pump to draw cooling water into the material guide chamber A of the air guide hose 6103, and then into the feed chamber of the cutting plate through the chamber A, to cool down the fixed cutting mesh 6212 and the movable cutting mesh 6223, so as to avoid the friction between the fixed cutting mesh 6212 and the movable cutting mesh 6223 during the cutting of sponge waste, which would affect the sponge and be detrimental to recycling;

[0073] After heat exchange, cooling water enters through the discharge chamber into the through chamber B, then into the guide chamber B, and finally returns to the interior of the cooler, where it continues to cool down using cooling plates.

[0074] Water pumps and cooling elements are existing technologies that can be purchased directly on the market, found in existing literature and journals, or searched on websites. They are well-known to those skilled in the art or are easily accessible.

[0075] In this embodiment of the invention, a method for processing sponge waste according to the above-described sponge waste recycling and processing device includes the following steps:

[0076] Step 1: Intelligent Diversion Tank

[0077] The waste sponge in the feed trough 100 is conveyed to the distribution hub by the conveying auger. The material density is identified by the pressure sensor (soft PU < 30 kg / m³, hard PU > 50 kg / m³) and automatically distributed to the corresponding recycling tank 400.

[0078] Step 2: Dynamic compression molding

[0079] Adjustable frame 610 dual adjustable frame coordinates control of sponge waste recycling chamber 500:

[0080] S1. The telescopic rod B6104 drives the limiting plate 6102 to move seamlessly along the tank wall, compressing the sponge waste recycling chamber 500 to the target volume (soft 5:1, hard 8:1).

[0081] S2. The pressure feedback system adjusts the compression force in real time (10kN for soft materials and 25kN for hard materials) to form a fixed spatial block with a density of not less than 150kg / m³.

[0082] Step 3: In-situ multi-stage grinding

[0083] The telescopic rod A6101 drives the cutting plates on the fixed cutting mesh 6212 and the movable cutting mesh 6223 to move crosswise, dividing the compressed block into 50 mm³ fragments, completing the primary crushing by the longitudinal and transverse cutting plates; the drive motor 6215 drives the movable cutting mesh 6223 to rotate relative to the fixed cutting mesh 6212 (speed 120 rpm); the cooler pumps cooling water through the guide chamber A, the feed chamber, the through chamber B and the guide chamber B in sequence to circulate and cool, so as to ensure that the crushing temperature does not exceed 60℃; thus completing the deep crushing by the rotating cutting mesh.

[0084] Pressure feedback systems are existing technology; they can be purchased directly from the market, found in existing literature and journals, or searched on websites. They are well-known to those skilled in the art or are easily accessible.

[0085] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0086] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments.
