Description

Technical Field

[0001] This invention relates to the field of rubber production technology, specifically to a production equipment and process for fast-dissolving fluid black gold rubber. Background Technology

[0002] Instantly soluble fluid black gold granules are made primarily from tire tread materials. Through high-temperature shearing and decrosslinking, the S-S or S-C bonds in the rubber are completely broken to form small molecules, achieving desulfurization. The product is fluid at high temperatures and paste at room temperature. The fluid rubber after high-temperature decrosslinking is mixed with other polymer materials for modification and then granulation. It is mainly used in tires, conveyor belts, shoe materials, waterproof materials, and asphalt pavement rubber modification materials. After application, it can effectively reduce the amount of oil, carbon black, natural rubber, and styrene-butadiene rubber used.

[0003] Current technologies for desulfurizing waste tire platforms primarily employ continuous spiral desulfurization equipment. During continuous desulfurization, the spiral structure conveys and shears the material forward. However, existing spiral structures mostly involve free conveying, primarily driven by thermochemical reactions, resulting in insufficient shearing force and impacting desulfurization efficiency. Furthermore, due to the large size and complex structure of spiral desulfurization equipment, high-temperature oxidation is easily generated during material conveying. To mitigate the effects of high-temperature oxidation during desulfurization, a spray structure is used for cooling in the middle of the desulfurization process, intermittently spraying water mist. However, existing spray devices, constantly exposed to the material, are prone to clogging the spray nozzles and do not effectively provide cooling. The material is in a viscous flow state during conveying within the cylinder, making it prone to adhering to the spiral and requiring routine cleaning. Existing cleaning methods require complete disassembly and reassembly of the cylinder, which is cumbersome and not conducive to rapid cleaning. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of desulfurization and cooling in the prior art, thereby providing a quick-dissolving fluid black gold rubber production equipment and process.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A fast-dissolving fluid black gold rubber production device includes a batching structure, a modification structure, a filtration structure, a granulation structure, and a packaging structure. The inlet end of the batching structure is connected to a rubber silo and a feeding silo. The outlet end of the batching structure is connected to the inlet end of the modification structure. A forced feeding component is also connected to the inlet end of the modification structure. The outlet end of the batching structure is connected to the forced feeding component. The outlet end of the modification structure is connected to the filtration structure. A refining component is provided at the outlet end of the filtration structure. The outlet end of the refining component is connected to the inlet end of the granulation structure. The granulation structure includes an underwater granulation component and a physical isolation component. A screening component is provided between the underwater granulation component and the physical isolation component. The packaging mechanism is located at the outlet end of the physical isolation component.

[0007] The modified structure includes a modified support component, a high-mixing modified component, and a desulfurization modified component arranged sequentially. Both the high-mixing modified component and the desulfurization modified component are mounted on the modified support component. The high-mixing modified component includes a first material cylinder, a first material cover, and a first screw that is rotatably mounted in the first material cylinder. The desulfurization modified component includes a second material cylinder, a second material cover, and a second screw that is rotatably mounted in the second material cylinder. The first screw and the second screw are coaxially arranged, and the second screw is located at the rear end of the first screw. The high-mixing modified component is also connected to a venting component and multiple spray structures. The desulfurization modified component is also connected to multiple spray structures. An exhaust component is connected to the desulfurization modified component near the discharge end.

[0008] By adopting the above technical solution, the rubber silo and feeding silo are mixed according to a certain formula and then transported to the batching structure for premixing before being input into the modification structure. The modification structure is fed quantitatively by a forced feeding component. The modification structure is modified in stages. First, it is mixed at high speed, heated and modified in a high-mixing modification component. Then, it is kept warm and sent to the desulfurization modification component for shear desulfurization modification. After that, it is extruded and cooled by a closed cooling component before being sent to the granulation structure for underwater granulation. During underwater granulation, a separating agent is added to the water. Subsequently, calcium powder is added with a physical separating component for secondary separation to prevent the rubber from sticking together. Finally, it is packaged in ton bags by the packaging structure.

[0009] This application enables the continuous production of fast-dissolving fluid black gold rubber, including formulation, staged modification, refining and filtration, cooling granulation, screening and packaging. The process employs a two-stage modification operation: first, high-speed mixing modification, followed by screw-driven forced shearing modification to achieve the recovery and pyrolysis of the rubber compound. Intermittent spray cooling is used during modification, and a sealed cooling system prevents high-temperature oxidation of the rubber compound after modification. After cooling, the rubber compound is refined in a refining mill to increase its fineness. Subsequent underwater granulation and physical isolation methods are used for granulation to reduce granulation odor and improve granulation fineness. The dual isolation operation ensures particle drying during transport and prevents oxidation and contamination of the rubber compound.

[0010] Furthermore, the screw one includes an integrally formed feeding section, heating section, and modification section; the barrel one includes an interconnected feeding barrel, heating barrel, and modification barrel; the feeding barrel, heating barrel, and modification barrel are all corresponding to the feeding section, heating section, and modification section; and the material cover one has multiple sections corresponding to the barrel one. The screw two includes an integrally formed insulation section, modification section two, venting section, and extrusion section; the barrel two includes an interconnected insulation barrel, modification section two, venting pipe, and extrusion barrel; the insulation barrel, modification section two, venting pipe, and extrusion barrel are all corresponding to the insulation section, modification section two, venting section, and extrusion section; and the material cover two has multiple sections corresponding to the barrel two.

[0011] By adopting the above technical solution, the rubber compound conveyed by the forced feeding component is sent to the feeding section for high-speed mixing and then to the heating section for heating. After heating, it undergoes a first modification stage. The screw spacing in the feeding section is larger than that in the heating section, and the heating section is also equipped with an intermittent screw structure. The first modification stage uses a screw structure in conjunction with a pin structure for high-speed modification. The modified rubber compound continues to be transported to the insulation section for slow conveying to avoid overheating. Then, the rubber compound continues to be sheared and modified in the second modification stage, and is vented in the venting section to prevent excessive air pressure in the barrel from causing safety accidents. Finally, it is extruded at the extrusion stage. The second modification stage also uses a screw structure in conjunction with a pin structure, and the venting section uses a screw structure in conjunction with an intermittent screw structure. The barrel and the cover are equipped with multiple sections corresponding to the screw, which facilitates disassembly, assembly, and maintenance.

[0012] Furthermore, connecting blocks extend outward from the sidewalls of the top length direction of both material cylinder one and material cylinder two. Each connecting block has a locking groove with a width decreasing from top to bottom. Locking blocks extend from the bottom of both sides of material cover one and material cover two along their length direction, corresponding to the locking grooves. The connecting blocks and locking blocks also have positioning bolt holes with diameters increasing from top to bottom. Mounting chucks are provided between adjacent feeding cylinders, heating cylinders, modification cylinder one, insulation cylinder, modification cylinder two, exhaust cylinder, and extrusion cylinder. Both ends of each feeding cylinder, heating cylinder, modification cylinder one, insulation cylinder, modification cylinder two, exhaust cylinder, and extrusion cylinder extend outward with inclined mounting rings. Mounting chucks have mounting grooves corresponding to the mounting rings. Locking bolts are also arranged in a circumferential array on the mounting chuck, with the axial direction of the locking bolts parallel to the axial direction of the mounting chuck.

[0013] By adopting the above technical solution, the material cylinder and the material cover are fixed by connecting and locking and reinforced with positioning bolts to ensure a firm connection between the material cylinder and the material cover during operation; different material cylinders are fixedly installed by using a retaining ring and a chuck, which not only connects the two material cylinders but also ensures a seal between them.

[0014] Furthermore, the modified support component includes a support frame and a support frame. The support frame is fixed inside the support frame and is correspondingly mounted with a chuck. The support frame is U-shaped and has a receiving groove at the top corresponding to the mounting chuck. Support rods are provided at the bottom of the support frame near the four corners. The two ends of the support rods are fixed to the side of the adjacent support frame near the bottom and the inner side of the support frame, respectively.

[0015] By adopting the above technical solution, the support frame is set with a corresponding chuck, which corresponds to the connection between the two segmented material cylinders. This not only provides support but also ensures the firmness of the connection between the two material cylinders, ensuring that the material cylinders are coaxial and the connection is seamless during operation, thereby achieving the stability of the material cylinder operation. The support rod connects the support frame and the bracket frame to improve the load-bearing capacity of the support frame, and at the same time avoids the influence of displacement caused by thermal expansion of the material cylinders during operation, always ensuring the coaxiality of the material cylinder connection and ensuring the safety of the material cylinders during operation.

[0016] Furthermore, multiple spray structures are connected to both the modified first cylinder and the modified second cylinder. Each spray structure includes a spray cylinder, a spray baffle, and two spray heads. The spray cylinder is vertically installed on the corresponding material cover one and material cover two of the modified first cylinder and modified second cylinder. The spray baffle and spray heads are installed inside the spray cylinder. The spray baffle is a hollow hemispherical shape and is positioned and rotated relative to the spray cylinder. The two spray heads are symmetrically arranged about the axis of the spray baffle, and the axis of the spray head is parallel to the axis of the spray cylinder. Two mist outlets are opened on the spray baffle corresponding to the spray head.

[0017] By adopting the above technical solution, the spray baffle is positioned and rotated inside the spray cylinder. When the spray head is working, the mist outlet is aligned with the spray head, which does not affect the spray cooling operation. When the spray head is not working, the spray baffle blocks the spray head. On the one hand, it can catch the water droplets dripping from the spray head, and on the other hand, it can block the spray head to prevent the adhesive from sticking and clogging the spray head, thereby affecting the subsequent spraying operation and hindering the cooling of the modified area.

[0018] Furthermore, a spray driving component extends from one side of the spray cylinder to drive the spray baffle to rotate. The spray driving component includes a drive motor, a drive turntable, and a deflector plate. The drive motor controls the rotation of the drive turntable. The axis of the drive turntable is perpendicular to the axis of the spray baffle and tangential to the top of the spray baffle. The deflector plate is arc-shaped and extends radially along the drive turntable. A deflector rod extends from the end of the deflector plate away from the drive turntable. The deflector rod is perpendicular to the side of the deflector plate. A deflector groove is provided on the spray baffle corresponding to the deflector rod. The deflector groove is arranged in a circumferential array along the spray baffle and along the height direction of the spray baffle. The top of the spray baffle also has a circumferential array of rotation grooves corresponding to the drive turntable. The end of the drive turntable also has a clearance groove corresponding to the spray baffle.

[0019] By adopting the above technical solution, the drive turntable is driven by the motor to rotate, which in turn drives the actuating plate to rotate. The rotation of the actuating plate causes the actuating rod to engage with the actuating groove on the spray baffle. When the actuating rod slides from the top to the bottom of the actuating groove, it drives the spray baffle to rotate 90°, thereby realizing the two states of the spray baffle corresponding to the spray head - blocking or misting. In order to avoid structural interference, the end of the drive turntable is also provided with a clearance groove corresponding to the spray baffle.

[0020] Furthermore, the spray cylinder is equipped with a mounting bracket for mounting a spray baffle and two spray heads. The mounting bracket includes a mounting frame and a hollow rotating rod. The mounting frame is arranged in a cross shape inside the spray cylinder. The rotating rod is rotatably mounted on the mounting frame and its bottom is engaged with the spray baffle. The mounting frame has a locking groove corresponding to the spray head. Near the bottom of the rotating rod, multiple liquid passage grooves are arranged in a circumferential array. The rotating rod is also provided with a drain pipe communicating with the outside along the axial direction. The bottom of the drain pipe is in contact with the bottom of the spray baffle.

[0021] By adopting the above technical solution, the mounting component is used to install and snap onto the spray baffle and two spray heads. The mounting bracket enables the positioning and rotation of the spray baffle and connects to the drain pipe. It can suck up the liquid dripping into the spray baffle, and can also pass cleaning liquid through the drain pipe to clean the inner wall of the barrel during routine cleaning.

[0022] Furthermore, a ventilation component is provided at the modified cylinder, which includes a ventilation cylinder, a ventilation head, and an air guide. The ventilation cylinder has a vertical axis and is fixed on the corresponding material cover of the modified cylinder. The ventilation head is vertically installed inside the ventilation cylinder and connected to an air source component. The air guide includes an air guide ring plate and a fixing plate. The air guide ring plate is hollow and semi-circular, and the air guide ring plate is fixed to the bottom of the material cover by the fixing plate.

[0023] By adopting the above technical solution, in order to reduce the possibility of rubber oxidation during the modification operation, nitrogen can be introduced into the barrel to isolate oxygen. The nitrogen is introduced through the gas source and accelerated at the air guide ring plate to form an annular air intake. Increasing the nitrogen flow rate also facilitates the subsequent filling of the gaps inside the barrel. It can also play a purging role during routine cleaning, which facilitates the barrel cleaning operation.

[0024] Furthermore, an exhaust device is provided at the modified second cylinder. The exhaust device includes a main exhaust cylinder, two pressure screws, and an exhaust pipe. The main exhaust cylinder is parallel to the axis of the pressure screws and perpendicular to the axis of the modified second cylinder. The two pressure screws are rotatably mounted in the main exhaust cylinder and positioned within it. A pressure drive is connected to the top of each pressure screw. The exhaust pipe is connected to the side wall of the main exhaust cylinder near the top. The main exhaust cylinder is fixed to the corresponding material cover two of the modified second cylinder via a connecting cylinder. The connecting cylinder is coaxial with the main exhaust cylinder and extends a receiving plate with a diameter larger than the connecting cylinder at its bottom. An exhaust port is provided on the material cover two corresponding to the connecting cylinder. A receiving interface corresponding to the receiving plate extends from the top of the exhaust port. A positioning ring also extends from the top of the connecting cylinder, and a positioning groove is provided inside the main exhaust cylinder corresponding to the positioning ring.

[0025] By adopting the above technical solution, the venting component uses a double-pressure screw to vent, preventing the rubber material from overflowing out of the main vent cylinder. The threads near the top of the pressure screw have opposite directions to those at the bottom, thus achieving the goal of venting only and preventing overflow. The receiving plate and connecting cylinder are used to install the main vent cylinder, ensuring a secure installation of the main vent cylinder and the venting cylinder, reducing the possibility of gas leakage at both locations, and minimizing the generation of rubber odor.

[0026] A process for producing fast-dissolving fluid black gold rubber, using the aforementioned production equipment, includes the following steps:

[0027] S1 Mixing: The 40-80 mesh rubber powder in the rubber silo and tall oil, antioxidant RD or lignin and other ingredients in the feeding silo are mixed according to the set formula and then transported to the mixing structure for premixing before being input into the modification structure. During the first stage of modification, 3 parts tall oil are added for every 100 parts of 40-80 mesh rubber powder. The modified structure is quantitatively fed through the forced feeding device.

[0028] S2 Modification: The modification is performed in stages. First, high-speed mixing and heating are carried out in the high-mixing modifier for a first-stage modification. During the high-mixing modification, the screw speed is 1440 rpm, the modification time is 2000 s, and the discharge temperature is controlled at 190℃ or the discharge current is 320A. The modified rubber compound is then fed into the desulfurization modifier for a second-stage shearing and desulfurization modification. During the second-stage modification, 2 parts lignin and 0.5 parts antioxidant RD are added per 100 parts of 40-80 mesh rubber powder. The screw is controlled by a motor, with a shearing speed of 70-75 rpm and a current control of 150A-160A. Before the modification of the modified structure, the inside of the barrel is vented through a venting device to isolate oxygen. During the modification operation, the spray structure is controlled to intermittently spray cooling. An exhaust device is installed in the later stages of the modification for exhaust operation.

[0029] S3 Post-processing: After the modified structure is extruded, the rubber compound is first cooled in a closed cooling unit, then refined in a refining unit, and finally sent to the granulation unit for underwater granulation. The cooling water temperature of the closed cooling unit is ≤25℃, the water pressure is ≥0.25MPa, the cooling screw speed is 20-30 rpm, and the discharge temperature is ≤90℃. The temperature of the refined compound is ≤25℃, the water pressure is ≥0.25MPa, the refining thickness is ≤15 mils, and the temperature of the refined rubber compound is ≤90℃.

[0030] S4 Screening and Packaging: After granulation, the product is screened and dried by a screening device, then sent to a physical isolation device to add calcium powder for secondary isolation, and finally packaged in ton bags through a packaging structure.

[0031] In summary, the technical solution of the present invention has the following advantages:

[0032] 1. The instant liquid black gold rubber production equipment provided by the present invention integrates a batching structure, a modification structure, a filtration structure, a granulation structure, and a packaging structure to form a continuous production line. This enables continuous production of instant liquid black gold rubber, including formulation batching, segmented modification, refining and filtration, cooling and granulation, and screening and packaging. This effectively improves production efficiency, reduces intermediate storage and material transfer, minimizes contact between the rubber compound and air during production, and prevents rubber compound oxidation.

[0033] 2. The fast-dissolving fluid black gold rubber production equipment provided by the present invention adopts a segmented modification method to achieve two-stage modification of the rubber compound. First, high-speed mixing modification is performed, and then screw forced shear modification is used to achieve the recovery and pyrolysis of the rubber compound. During the modification process, intermittent spray cooling is used, and after modification, the rubber compound is protected from high-temperature oxidation by a sealed cooling component. After cooling, the rubber compound is refined and compensated by a refining machine to increase the fineness of the rubber compound, effectively improving the quality of the rubber compound.

[0034] 3. The quick-dissolving fluid black gold rubber production equipment provided by the present invention uses a venting component to introduce nitrogen gas before rubber production to isolate oxygen and reduce the possibility of rubber oxidation. During routine cleaning of the barrel, the venting component can also perform purging to ensure the cleaning effect. During the modification process, an exhaust component is set to perform exhaust operation on the rubber modification process to ensure stable and safe air pressure during the modification process. The exhaust component adopts a twin-screw structure design to avoid the overflow of rubber material at the exhaust pipe and the main exhaust pipe.

[0035] 4. The fast-dissolving fluid black gold rubber production equipment provided by the present invention adopts underwater granulation components for underwater granulation operation. On the one hand, it can reduce granulation odor, and on the other hand, it can facilitate the rapid cooling and molding of rubber granules, effectively improving the granulation quality. Underwater granulation, combined with the subsequent addition of calcium powder for isolation, achieves two physical isolation operations on the rubber material, preventing the rubber granules from sticking together and facilitating the subsequent packaging operation of rubber granules.

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0048] A type of equipment for producing fast-dissolving fluid black gold rubber, such as Figure 1As shown, the structure includes a batching structure 01, a modification structure 02, a filtration structure 03, a granulation structure 04, and a packaging structure 05. The inlet end of the batching structure 01 is connected to a rubber hopper 011 and a feeding hopper 012. The outlet end of the batching structure 01 is connected to a forced feeding component 026, which is connected to the inlet end of the modification structure 02. The outlet end of the modification structure 02 is connected to the filtration structure 03. A sealed cooling component 027 is provided at the filtration structure 03, and the sealed cooling component 027 includes a cooling cylinder 05. 271 and cooling screw 0272, the cooling screw 0272 is rotatably installed in the cooling cylinder 0271, the discharge end of the filter structure 03 is provided with a refining part 031, the discharge end of the refining part 031 is connected to the feed end of the granulation structure 04, the granulation structure 04 includes an underwater granulation part 041 and a physical isolation part 042, a screening part 043 is also provided between the underwater granulation part 041 and the physical isolation part 042, and the packaging structure 05 is set at the discharge end of the physical isolation part 042. The rubber compound bins 011 and 012 are mixed according to a certain formula and then transported to the batching structure 01 for premixing before being fed into the modification structure 02. The modification structure 02 is fed by the forced feeding component 026. The modification is carried out in stages at the modification structure 02. First, it is modified by the high-mixing modification component 2, and then sent to the desulfurization modification component 3 for shear desulfurization modification. After that, it is extruded and cooled by the closed cooling component 027, then refined by the refining component 031, and then sent to the granulation structure 04 for underwater granulation. After granulation, it is dried and then screened by the screening component 043. Then it is sent to the physical isolation component 042 for secondary isolation operation, and finally packaged in ton bags by the packaging structure 05.

[0049] like Figure 1 and Figure 2 As shown, the modified structure 02 includes a modified support 1, a high-mixing modified component 2, and a desulfurization modified component 3 arranged sequentially. Both the high-mixing modified component 2 and the desulfurization modified component 3 are mounted on the modified support 1. The high-mixing modified component 2 is also connected to a venting component 4 and multiple spray structures 5, each of which is individually connected to a water pipe (not shown in the figure). The desulfurization modified component 3 is also connected to multiple spray structures 5, and an exhaust component 6 is connected near the discharge end of the desulfurization modified component 3. A two-stage modification operation is adopted: first, high-speed mixing modification, and then forced shearing modification via a screw to achieve the recovery and pyrolysis of the rubber compound. Intermittent spray cooling is used during the modification process, and after modification, a sealed cooling component 027 is used to prevent high-temperature oxidation of the rubber compound. After cooling, the rubber compound is refined and compensated by a refining mill to increase its fineness. Subsequently, underwater granulation and physical isolation methods are used for granulation to reduce granulation odor and improve granulation fineness. The dual isolation operation achieves particle drying during transportation and prevents the rubber compound from being mixed with oxidation.

[0050] like Figure 2 and Figure 3As shown, the high-mixing modified part 2 includes a material cylinder 21, a material cover 22, and a screw 23 that is rotatably mounted in the material cylinder 21. The screw 23 includes an integrally formed feeding section 231, a heating section 232, and a modification section 233. The material cylinder 21 includes an interconnected feeding cylinder 211, a heating cylinder 212, and a modification cylinder 213. The feeding cylinder 211, the heating cylinder 212, and the modification cylinder 213 are all corresponding to the feeding section 231, the heating section 232, and the modification section 233. The material cover 22 has multiple sections corresponding to the material cylinder 21. The rubber compound conveyed by the forced feeding component 026 is sent to the feeding section 231 for high-speed mixing, and then conveyed to the heating section 232 for heating. After heating, it undergoes a modification process in the modification section 233. The screw pitch of the feeding section 231 is larger than that of the heating section 232, and the heating section 232 is also equipped with an intermittent screw structure. The modification section 233 performs high-speed modification operations through a screw structure in conjunction with a pin structure. The material cover 22 and the material cylinder 21 are equipped with multiple sections corresponding to the material cylinder 21, which facilitates disassembly, assembly, and maintenance.

[0051] The desulfurization modification component 3 includes a second material cylinder 31, a second material cover 32, and a second screw 33 that is rotatably installed inside the second material cylinder 31. The first screw 23 and the second screw 33 are coaxially arranged, and the second screw 33 is located at the rear end of the first screw 23. The input drive of the first screw 23 is located at the left end to control the rotation of the first screw. The input drive of the second screw 33 is driven by a motor and is located outside the corresponding material cover 32. Although the first screw 23 and the second screw 33 are coaxially arranged, their rotation speed can be adjusted according to the set requirements. The screw 2 33 includes an integrally formed insulation section 331, modification section 332, venting section 333, and extrusion section 334. The barrel 2 31 includes an interconnected insulation cylinder 311, modification cylinder 312, venting cylinder 313, and extrusion cylinder 314. The insulation cylinder 311, modification cylinder 312, venting cylinder 313, and extrusion cylinder 314 are all corresponding to the insulation section 331, modification section 332, venting section 333, and extrusion section 334. The material cover 2 32 has multiple sections corresponding to the barrel 2 31. The modified rubber compound is transported to the insulation section 331 for slow conveying to avoid overheating. Then, the rubber compound is further sheared and modified in the modification section 332, and venting is performed in the venting section 333 to prevent excessive air pressure in the barrel from causing a safety accident. Finally, it is extruded at the extrusion section 334. The modification section 332 also has a spiral structure with a pin structure, and the venting section 333 has a spiral structure with an intermittent spiral structure. The material cover 2 32 and the material cylinder 2 31 are provided with multiple sections corresponding to the material cylinder 2 31, which also facilitates disassembly, assembly and maintenance operations.

[0052] like Figure 3 and Figure 5As shown, connecting blocks 021 extend outward from the sidewalls of the top length of both material cylinder 21 and material cylinder 31. The length of the connecting blocks 021 is equal to that of the corresponding segmented material cylinder. Connecting blocks 021 have engagement grooves 0211 whose width decreases from top to bottom. The engagement grooves 0211 have an isosceles cross-section. Engaging blocks 022 extend from the bottom of both sides of material cover 22 and material cover 32 along their length, corresponding to the engagement grooves 0211. Positioning bolt holes 0221 with increasing diameters from top to bottom are also provided between the connecting blocks 021 and the engagement blocks 022. The positioning bolt holes 0221 on the connecting blocks 021 and the engagement blocks 022 are integrally extended, and positioning bolts are inserted into the positioning bolt holes 0221 to fix the material cover to the material cylinder. The material cylinder and material cover are fixed by connecting and engaging, and reinforced with positioning bolts to ensure a firm connection between the material cylinder and material cover during operation.

[0053] The feeding cylinder 211, heating cylinder 212, modification cylinder 1 213, insulation cylinder 311, modification cylinder 2 312, exhaust cylinder 313, and extrusion cylinder 314 are connected by mounting chucks 023 between adjacent units. Each of these units has outwardly extending inclined mounting rings 024 at both ends along its length. Mounting grooves 0231 extend from the mounting chucks 023 corresponding to the mounting rings 024. Locking bolts 025 are also arranged in a circumferential array on the mounting chucks 023, with their axial direction parallel to that of the mounting chucks 023. The different cylinders are fixedly installed by the mounting rings 024 engaging with the mounting chucks 023, achieving connection between the two cylinder sections while ensuring a seal between them.

[0054] like Figure 3 and Figure 5 As shown, the modified support component 1 includes a support frame 11 and a support frame 12. The support frame 12 is fixed inside the support frame 11 and is correspondingly mounted on a chuck 023. The support frame 12 is U-shaped and has a receiving groove 121 at its top corresponding to the mounting chuck 023. Support rods 122 are provided at the bottom of the support frame 12 near the four corners. The two ends of the support rods 122 are fixed to the side of the adjacent support frame 12 near the bottom and the inner side of the support frame 11, respectively. The support frame 12 is positioned corresponding to the mounting chuck 023, which corresponds to the connection point of the two segmented material cylinders. This not only provides support but also ensures the firmness of the connection between the two material cylinders, ensuring that the material cylinders are coaxial and the connection is seamless during operation, thereby achieving the stability of the material cylinder operation. The support rods 122 connect the support frame 12 and the support frame 11, increasing the load-bearing capacity of the support frame 12 and preventing the material cylinders from shifting due to thermal expansion during operation, thus ensuring the coaxiality of the material cylinder connection and the safety of the material cylinders during operation.

[0055] like Figure 3 , Figure 7 and Figure 8 As shown, multiple spray structures 5 are connected to both the modified first cylinder 213 and the modified second cylinder 312. Each spray structure 5 includes a spray cylinder 51, a spray baffle 52, and two spray heads 53. The spray cylinder 51 is vertically installed on the corresponding material cover 22 and material cover 32 of the modified first cylinder 213 and modified second cylinder 312. The spray baffle 52 and the spray heads 53 are both installed inside the spray cylinder 51. The spray baffle 52 is a hollow hemisphere and is positioned and rotated relative to the spray cylinder 51. The two spray heads 53 are symmetrically arranged about the axis of the spray baffle 52, and the axis of the spray head 53 is parallel to the axis of the spray cylinder 51. Two mist outlets 521 are opened on the spray baffle 52 corresponding to the spray head 53.

[0056] The spray cylinder 51 is equipped with a mounting component 511 for mounting a spray baffle 52 and two spray heads 53. The mounting component 511 includes a mounting bracket 5111 and a hollow rotating rod 5112. The mounting bracket 5111 is arranged in a cross shape inside the spray cylinder 51. The rotating rod 5112 is rotatably mounted on the mounting bracket 5111 and its bottom is engaged with the spray baffle 52. The mounting bracket 5111 has a corresponding slot 51111 on the spray head 53. Near the bottom of the rotating rod 5112, multiple liquid passage grooves 51121 are arranged in a circumferential array. The rotating rod 5112 is also provided with a drain pipe 5113 communicating with the outside along the axial direction. The bottom of the drain pipe 5113 is in contact with the bottom of the spray baffle 52. Mounting component 511 is used to mount and snap onto the spray baffle 52 and two spray heads 53. Mounting bracket 5111 enables the spray baffle 52 to be positioned and rotated, and connects to the drain pipe 5113. It can suck up liquid dripping into the spray baffle 52, and during routine cleaning, it can also introduce cleaning liquid through the drain pipe 5113 to clean the inner wall of the cylinder. During cylinder cleaning, the flow rate of the drain pipe 5113 can be increased while simultaneously rotating the spray baffle 52, thereby increasing the water flow and creating a rotating spray, facilitating the cleaning operation of the inner wall of the cylinder.

[0057] A spray drive component 54 extends from one side of the spray cylinder 51 to drive the spray baffle 52 to rotate. The spray drive component 54 includes a drive motor 541, a drive turntable 542, and a deflector plate 543. The drive motor 541 controls the rotation of the drive turntable 542. The axis of the drive turntable 542 is perpendicular to the axis of the spray baffle 52 and tangential to the top of the spray baffle 52. The deflector plate 543 is arc-shaped and conforms to the outer side of the spray baffle 52, extending radially along the drive turntable 542. The deflector plate 543 is located away from the drive turntable 542. One end of the rotating disk 542 extends a toggle lever 5431, which is perpendicular to the side of the toggle plate 543. A toggle groove 522 is provided on the spray baffle 52 corresponding to the toggle lever 5431. The toggle groove 522 is arranged in a circumferential array along the spray baffle 52 and along the height direction of the spray baffle 52. The top of the spray baffle 52 is also arranged in a circumferential array with a rotation groove 523 corresponding to the driving disk 542. In order to avoid structural interference, the end of the driving disk 542 is also provided with a clearance groove 5421 corresponding to the spray baffle 52. The drive turntable 542 is controlled by the drive motor 541 to rotate, which in turn drives the actuating plate 543 to rotate. The rotation of the actuating plate 543 causes the actuating rod 5431 to engage with the actuating groove 522 on the spray baffle 52. When the actuating rod 5431 rotates along the axis of the drive motor 541, it also slides in the actuating groove 522. Thus, when the actuating rod 5431 slides from the top to the bottom of the actuating groove 522, it drives the spray baffle 52 to rotate 90° along the vertical axis, thereby realizing the two states of the spray baffle 52 corresponding to the spray head 53 - blocking or misting, and thus controlling the switching of the state of the spray baffle 52 corresponding to the spray head 53.

[0058] like Figure 3 and Figure 6 As shown, the first modification cylinder 213 is also equipped with a feeding port (not shown in the figure), which adds modifier during the second modification process. A ventilation component 4 is provided at the first modification cylinder 213. The ventilation component 4 includes a ventilation cylinder 41, a ventilation head 42, and a guide component 43. The ventilation cylinder 41 has a vertical axis and is fixed to the corresponding material cover 22 of the first modification cylinder 213. The ventilation head 42 is vertically installed inside the ventilation cylinder 41 and connected to an air source component (not shown in the figure). The guide component 43 includes a guide ring plate 431 and a fixing plate 432. The guide ring plate 431 is hollow and semi-circular with air outlets at both ends near the bottom. The guide ring plate 431 is fixed to the bottom of the material cover 22 by two fixing plates 432 near the top. To reduce the possibility of rubber oxidation during modification operations, nitrogen can be introduced into the barrel to isolate oxygen. The nitrogen is introduced through the gas source and accelerated at the air guide ring plate 431 to form an annular air intake. Increasing the nitrogen flow rate also facilitates the subsequent filling of the gaps inside the barrel. It can also play a purging role during routine cleaning, making barrel cleaning operations easier.

[0059] like Figure 3 and Figure 4As shown, an exhaust component 6 is provided at the modified secondary cylinder 312. The exhaust component 6 includes a main exhaust cylinder 61, two pressing screws 62, and an exhaust pipe 63. The exhaust pipe 63 is connected to a waste gas incineration device for waste gas treatment. The main exhaust cylinder 61 is fixed to the material cover 32 corresponding to the modified secondary cylinder 312 via a connecting cylinder 612. The connecting cylinder 612 is coaxially arranged with the main exhaust cylinder 61 and has a receiving plate 6121 with a diameter larger than that of the connecting cylinder 612 extending from its top. An exhaust port 321 is provided on the material cover 32 corresponding to the connecting cylinder 612. A receiving interface 322 corresponding to the receiving plate 6121 extends from the top of the exhaust port 321. A positioning ring 6122 also extends from the top of the connecting cylinder 612. A positioning groove 611 is provided inside the main exhaust cylinder 61 corresponding to the positioning ring 6122. The receiving plate 6121 and the connecting cylinder 612 are used to install the main exhaust cylinder 61, which ensures the stability of the main exhaust cylinder 61 and reduces the possibility of gas leakage at the exhaust pipe 313 and the main exhaust cylinder 61, thereby reducing the generation of rubber odor.

[0060] The main discharge cylinder 61 and the pressing screw 62 are parallel to each other and perpendicular to the axis of the modified double cylinder 312. The two pressing screws 62 are rotatably mounted in the main discharge cylinder 61 and are positioned in a rotatable manner. The pressing screws 62 are arranged side by side in the main discharge cylinder 61. A pressing drive component 621 is connected to the top of the pressing screw 62. The vent pipe 63 is connected to the side wall of the main discharge cylinder 61 near the top. The vent pipe 63 performs venting operation through the double pressing screws 62 to prevent the rubber material from overflowing out of the cylinder along the main discharge cylinder 61. The thread direction near the top of the pressing screw 62 is opposite to the thread direction at the bottom, thus achieving the purpose of venting only and preventing material overflow.

[0061] A process for producing fast-dissolving fluid black gold rubber, using the aforementioned production equipment, includes the following steps:

[0062] S1 Mixing: The 40-80 mesh rubber powder in the rubber silo and tall oil, antioxidant RD or lignin and other ingredients in the feeding silo are mixed according to the set formula and then transported to the mixing structure for premixing before being fed into the modification structure. During modification, 3 parts tall oil are added for every 100 parts of 40-80 mesh rubber powder. The modified structure is quantitatively fed through a forced feeding device. The raw material of the rubber compound comes from the soft top part of the steel radial truck tire, excluding the tire airtight layer. The temperature during the rubber crushing and powdering process does not exceed 100℃. The rubber powder is subjected to 7 magnetic separations to control the iron content of the rubber powder to within 0.03%. The rubber powder is graded and screened to a mesh size of 40-80 mesh to ensure the uniformity of subsequent modification. The tall oil is refined tall oil, with a total content of 15 polycyclic aromatic hydrocarbons of 10ppm. The softening point of the tall oil is 55-65℃ and its moisture and ash content are both <1%.

[0063] S2 Modification: The modification is performed in stages. First, high-speed mixing and heating are carried out in the high-mixing modifier for a first-stage modification. During the high-mixing modification, the screw speed is 1440 rpm, the modification time is 2000 s, and the discharge temperature is controlled at 190℃ or the discharge current is 320A. The modified rubber compound is then fed into the desulfurization modifier for a second-stage shearing and desulfurization modification. During the second-stage modification, 2 parts lignin and 0.5 parts antioxidant RD are added per 100 parts of 40-80 mesh rubber powder. The screw is controlled by a motor, with a shearing speed of 70-75 rpm and a current control of 150A-160A. Before the modification of the modified structure, the inside of the barrel is vented through a venting device to isolate oxygen. During the modification operation, the spray structure is controlled to intermittently spray cooling. An exhaust device is installed in the later stages of the modification for exhaust operation.

[0064] The production formula for the first stage of modification involves adding 3 parts tall oil per 100 parts of 40-80 mesh rubber powder, while the formula for the second stage of modification involves adding 2 parts lignin and 0.5 parts antioxidant RD per 100 parts of 40-80 mesh rubber powder. The control speed and the additives used in the first and second stages of modification are different. Staged modification achieves complete reversion and pyrolysis of the rubber compound, improving the quality of the final product.

[0065] S3 Post-processing: After the modified structure is extruded, the rubber compound is first cooled in a closed cooling unit, then refined in a refining unit, and then sent to the granulation structure for underwater granulation. The particle size of the underwater granulation is ≤2.0mm and the ratio of underwater release agent to water is 15:100. In the closed cooling unit, the temperature is cooled by water cooling through an external water cylinder. The cooling water temperature in the closed cooling unit is ≤25℃, the water pressure is ≥0.25MPa, the cooling screw speed is 20-30 rpm, and the discharge temperature is ≤90℃. In the refining unit, the temperature is ≤25℃, the water pressure is ≥0.5KPa, the refining thickness is ≤15 mils, and the refining compound temperature is ≤90℃.

[0066] S4 Screening and Packaging: After granulation, the material is first centrifuged and dehydrated, then conveyed to the screening unit under negative pressure for sieving and drying. The centrifugal dehydration speed is 240 r / min, and the screening particle size of the screening unit is 2.5 mm aperture. Afterwards, it is sent to the physical isolation unit to add calcium powder for secondary isolation. 0.8%-1% calcium powder is mixed into the rubber compound. Finally, it is packaged in ton bags through the packaging structure. The packaging temperature is below 40℃.

[0067] The working principle and usage of this fast-dissolving fluid black gold rubber production equipment: The rubber compound bins 011 and 012 are mixed according to a specific formula and then conveyed to the mixing structure 01 for premixing before being fed into the modification structure 02. The forced feeding component 026 provides forced quantitative feeding to the modification structure 02. Segmented modification occurs at the modification structure 02. First, it undergoes high-speed mixing, heating, and primary modification through the high-mixing modification component 2, then is kept warm and fed into the desulfurization modification component 3 for shear desulfurization modification. During modification at the modification structure 02, ventilation is first used... Part 4 vents the inside of the barrel to isolate oxygen. During the modification operation, intermittent spray cooling is used to avoid high-temperature oxidation. In the middle and later stages of modification, exhaust part 6 is set to exhaust the air to ensure the safety and stability of the modification process. After the modification is completed, the granules are extruded and cooled by the sealed cooling part 027 before being sent to the granulation structure 04 for underwater granulation. During underwater granulation, a separating agent is added to the water. After granulation, the granules are screened and dried by the screening part 043. Subsequently, calcium powder is added with the physical separation part 042 for secondary separation. Finally, the granules are packaged in ton bags by the packaging structure 05.
