A rubber recycling and regenerating particle production equipment

Abstract

This invention belongs to the field of rubber recycling and crushing technology, and particularly relates to a rubber recycling and regenerating granulation production equipment. The equipment includes a recycling chamber, within which, vertically arranged from top to bottom, are a primary crushing chamber, a secondary crushing chamber, and a tertiary crushing chamber. The primary crushing chamber is located at the top right of the recycling chamber, the secondary crushing chamber at the leftmost side, and the tertiary crushing chamber between the primary and secondary crushing chambers. This invention ensures that small-sized materials that meet the particle size requirements are promptly screened out and discharged, preventing them from entering subsequent crushing stages. This significantly reduces over-crushing, resulting in a substantial decrease in the yield of fine powder and improved quality of the finished granules. The secondary crushing chamber only processes large-sized materials that truly require crushing, preventing small particles from occupying the crushing chamber volume, thus improving processing efficiency, reducing erosion and wear on the crushing teeth by small particles, and extending the service life and maintenance cycle of the crushing mechanism.

Description

Technical Field

[0001] This invention belongs to the field of rubber recycling and crushing technology, and particularly relates to a rubber recycling and regeneration granulation production equipment. Background Technology

[0002] The resource recycling of waste rubber materials such as used tires is an important component of the circular economy. Currently, physical crushing (room temperature mechanical crushing) is one of the mainstream processes for producing rubber granules and powder. Its typical process includes: whole tire pretreatment, primary coarse crushing, secondary medium crushing, tertiary fine crushing / grinding, and multi-stage screening, magnetic separation, and fiber separation. In actual production, the rubber granules obtained after primary crushing have a wide particle size distribution (usually ranging from 5mm to 100mm), including large and medium-sized materials requiring further crushing, as well as small-sized materials and even fine powder that have basically met downstream requirements.

[0003] In traditional multi-stage crushing processes, all material from the primary crushing stage, regardless of particle size, is directly fed into the secondary crusher for further crushing, and then sequentially into the tertiary crushing and screening stages. This "all-material-through" crushing method has the following drawbacks:

[0004] 1. Small particles that have reached or are close to the target particle size are subjected to further impact and shearing during secondary crushing, resulting in over-crushing and the generation of a large amount of undesirable fine powder (<80 mesh), which reduces product quality, especially for applications with strict requirements on particle size distribution, such as sports field granules and asphalt modification.

[0005] 2. The secondary crusher processes large, medium and small materials simultaneously. Small particles occupy part of the crushing chamber volume and throughput, which restricts the equipment's processing efficiency for the large and medium-sized materials that actually need to be crushed, becoming a bottleneck in the overall production capacity.

[0006] 3. Although small particles have relatively low hardness, the continuous scouring action during feeding will accelerate the abrasive wear of blades or other vulnerable parts, increasing maintenance costs and downtime.

[0007] To address the aforementioned issues, some production lines have attempted to separate crushing and grading by adding a screening stage. However, existing solutions mostly involve unified screening after crushing, failing to achieve dynamic matching between the crushing path and the material particle size. Therefore, how to divert the material according to its particle size after primary crushing, allowing different particle sizes of rubber blocks to enter the appropriate next-stage crushing equipment, thereby reducing over-grinding, decreasing energy consumption, increasing production capacity, and optimizing product particle size distribution, is a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a rubber recycling and regeneration granule production equipment, which solves the problems mentioned in the background section.

[0009] To achieve the above objectives, this application provides the following technical solution: This invention provides a rubber recycling and regenerating granule production equipment, including a recycling box. Inside the recycling box, from top to bottom, are arranged a primary crushing box, a secondary crushing box, and a tertiary crushing box. The primary crushing box is located at the top right of the recycling box, the secondary crushing box is located at the leftmost of the recycling box, and the tertiary crushing box is located between the primary and secondary crushing boxes. Each crushing box is vertically connected and each box contains a crushing mechanism. Two vertically distributed screening and conveying mechanisms are provided inside the recycling box, and a discharge mechanism extending from the bottom of the recycling box to the outside is provided. The screening and conveying mechanism includes a filter belt disposed within the recycling box. A conveyor belt is rotatably mounted on the surface of the filter belt, and the conveyor belt circulates, moving the crushed material on the surface of the filter belt towards the next primary crushing box. The upper filter belt is divided from right to left into a first screening section and a second screening section, and the lower filter belt is entirely configured as a third screening section. The filter holes in the first and third screening sections are the same and smaller than those in the second screening section. The upper filter belt, via a corresponding conveyor belt, pushes the material falling from the primary crushing chamber from right to left. Material smaller than the diameter of the first screening section's filter holes falls directly onto the lower discharge mechanism; material between the diameters of the first and second screening sections' filter holes is transferred to the tertiary crushing chamber; and material larger than the diameter of the second screening section's filter holes is pushed to the secondary crushing chamber. The lower filter belt receives material from the secondary crushing chamber and moves it from left to right via a corresponding conveyor belt. Material smaller than the diameter of the third screening section's filter holes falls onto the discharge mechanism; and material larger than the diameter of the third screening section's filter holes is pushed to the tertiary crushing chamber.

[0010] According to an advantageous embodiment, the crushing mechanism includes two crushing shafts rotatably disposed within a primary crushing box. One end of the two crushing shafts is connected by a gear set for transmission. Multiple crushing teeth are arranged on the crushing shafts along their length direction, and the crushing teeth on the two crushing shafts are staggered. A crushing motor is fixedly disposed on the outside of the regeneration box, directly opposite the primary crushing box. The output shaft of the crushing motor is fixedly connected to one end of the crushing shaft.

[0011] According to an advantageous embodiment, the distance between the crushing teeth on the crushing shafts in the shredding box and each stage of the crushing box decreases sequentially.

[0012] According to an advantageous embodiment, a guide plate that is symmetrically distributed and inclined is fixedly provided on the upper side of the upper port of the three-stage crushing box.

[0013] According to an advantageous embodiment, a winding assembly is provided at both the front and rear ends of the filter belt, and a back-blowing assembly is provided at both the front and rear ends of the filter belt inside the regeneration box. The filter belt is moved and repositioned in the front-back direction by the winding assembly and back-blowing is performed on the filter belt by the back-blowing assembly. Collection boxes for collecting clogging materials are installed on the bottom front and rear side walls inside the regeneration box.

[0014] According to an advantageous embodiment, the winding assembly includes three guide rollers and a winding roller rotatably disposed between the left and right inner walls of the recycling box. The three guide rollers and the winding roller are rectangularly distributed. One end of the filter belt is fixedly connected to the winding roller and sequentially sleeved on the three corresponding guide rollers. The same end of two winding rollers connected to the same filter belt is connected by a pulley group for transmission. Two winding motors are fixedly disposed on the left side of the recycling box, and the output shaft of the winding motor is connected to one end of the corresponding winding roller.

[0015] According to an advantageous embodiment, the backflush assembly includes a hollow air distribution plate fixedly disposed between the left and right inner walls of the regeneration chamber, and a backflush nozzle evenly distributed along its length is disposed on the side of the hollow air distribution plate near the back of the corresponding filter belt.

[0016] According to an advantageous embodiment, the transfer belt includes two main conveyor belts symmetrically distributed front and rear, with a plurality of pusher plates evenly arranged between the two main conveyor belts along their length direction. Transfer rollers are sleeved at both ends of the two conveyor belts, and the two ends of the transfer rollers are rotatably connected to the front and rear inner sidewalls of the recycling box, respectively. Two transfer motors are fixedly arranged vertically on the front side of the recycling box, and the output shaft of the transfer motor is fixedly connected to the rear end of one of the transfer rollers at the same horizontal position.

[0017] According to an advantageous embodiment, the upper side of the recycling box is provided with a feed inlet corresponding to the primary crushing box, and the bottom right side of the recycling box is provided with a discharge outlet, and the front and rear sides of the recycling box are also provided with transparent windows extending from bottom to top.

[0018] According to an advantageous embodiment, the discharge mechanism is configured as a belt conveyor.

[0019] Compared with existing technologies, the rubber recycling and regenerating granule production equipment provided in this invention has the following beneficial effects: This equipment, by setting up upper and lower screening and transfer mechanisms and forming a closed-loop path of "crushing-screening-diversion-re-crushing" between each level of crushing chamber, achieves dynamic matching between material particle size and crushing stages. Compared to the traditional process of directly feeding all primary crushed material into the secondary crushing stage, this ensures that small-sized materials that meet the particle size requirements are promptly screened out and discharged, avoiding entry into subsequent crushing stages. This significantly reduces over-crushing, significantly lowers the yield of fine powder, and improves the quality of the finished granules. The secondary crushing chamber only processes the large-sized materials that truly need crushing, preventing small particles from occupying the crushing chamber volume, thus improving processing efficiency, reducing the erosion and wear of the crushing teeth by small particles, and extending the service life and maintenance cycle of the crushing mechanism.

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will now be described in further detail.

[0028] Please refer to the following: Figures 1-3A rubber recycling and regenerating pellet production equipment includes a recycling box 1. The recycling box 1 is characterized by the following features: a primary crushing box 2, a secondary crushing box 3, and a tertiary crushing box 4 are arranged sequentially from top to bottom within the recycling box 1. A guide plate 8, symmetrically distributed and inclined, is fixedly installed on the upper side of the upper port of the tertiary crushing box 4. Each crushing box is vertically connected and equipped with a crushing mechanism 5. Two screening and conveying mechanisms 6 are arranged vertically within the recycling box 1. A discharge mechanism 7 extending from the inside to the outside is installed at the bottom of the recycling box 1. An inlet corresponding to the primary crushing box 2 is located on the upper side of the recycling box 1, and an outlet is located on the bottom right side of the recycling box 1. Transparent windows extending upwards are also provided on the front and rear sides of the recycling box 1 to facilitate observation of the material inside the recycling box 1.

[0029] The upper screening and transfer mechanism 6 is located below the primary crushing box 2 and above the secondary crushing box 3 and the tertiary crushing box 4. The lower screening and transfer mechanism 6 is located below the primary crushing box 2 and below the secondary crushing box 3, and above the tertiary crushing box 4. The primary crushing box 2 is located at the top right of the regeneration box 1. The secondary crushing box 3 is located at the top left of the regeneration box 1. The tertiary crushing box is located between the primary crushing box 2 and the secondary crushing box 3.

[0030] See Figures 3-5 The discharge mechanism 7 is a belt conveyor, comprising two discharge rollers. One discharge roller is rotatably mounted between the leftmost front and rear inner walls of the bottom of the recycling tank 1, while the other discharge roller is rotatably mounted on the ground via a bracket. A discharge conveyor belt is fitted between the two discharge rollers. A corresponding conveyor motor is mounted on the bracket, and the conveyor motor is fixedly connected to one end of the corresponding discharge roller. The discharge conveyor belt extends from the leftmost side inside the recycling tank 1 to its outside. The conveyor motor drives the conveyor roller to rotate the discharge conveyor belt, cyclically discharging small-diameter materials from the bottom of the recycling tank 1.

[0031] See Figures 3-5 Taking the primary crushing box 2 as an example, the crushing mechanism 5 includes two crushing shafts rotatably disposed within the primary crushing box 2. One end of the two crushing shafts is connected by a gear set for transmission, and multiple crushing teeth are arranged along the length of each crushing shaft. The crushing teeth on the two crushing shafts are staggered. A crushing motor is fixedly disposed on the outside of the regeneration box 1, directly opposite the primary crushing box 2. The output shaft of the crushing motor is fixedly connected to one end of the crushing shaft. The spacing between the crushing teeth on the crushing shafts corresponding to the primary crushing box 2, the secondary crushing box 3, and the tertiary crushing box 4 decreases sequentially.

[0032] The crushing motor drives the crushing shaft, and the two crushing shafts rotate synchronously under the transmission of the gear set. The crushing teeth crush the rubber material that falls between the two crushing shafts.

[0033] See Figures 3-6 The screening and transfer mechanism 6 includes a filter belt 61 installed in the regeneration box 1. A transfer belt 62 is rotatably mounted on the surface of the filter belt 61. The transfer belt 62 circulates and drives the crushed material on the surface of the filter belt 61 to move towards the next-level crushing box 2. The upper filter belt 61 is divided into a first screening section 611 and a second screening section 612 from right to left. The lower filter belt 61 is configured as a third screening section 613. The filter holes of the first screening section 611 and the third screening section 613 are the same and smaller than those of the second screening section 612.

[0034] The filter holes in the first screening section 611 and the third screening section 613 are used to directly screen small-diameter materials and then send them to the discharge mechanism 7 for discharge. The filter holes in the second screening section 612 are used to directly send medium-diameter materials into the three-stage crushing box 4.

[0035] The upper filter belt 61 is located directly below the primary crushing box 2, and its horizontal projection covers the discharge port of the primary crushing box 2, the inlet of the secondary crushing box 3, and the inlet of the tertiary crushing box 4; the lower screening and transfer mechanism 6 is located directly below the secondary crushing box 3, and its horizontal projection covers the discharge port of the secondary crushing box 3 and the inlet of the tertiary crushing box 4.

[0036] In specific operation: The material to be processed enters the recycling box 1 through the feed inlet above it and then falls into the primary crushing box 2. After being crushed by the crushing mechanism 5 in the primary crushing box 2, the material falls into the first screening section 611 on the right side of the upper filter belt 61. The upper filter belt 61 contains three types of material with small, medium and large particle sizes (mainly large particle size, some medium particle size and a small part small particle size, the small particle size being rubber particles that meet the requirements). The different particle sizes on the upper filter belt 61 are simultaneously pushed from right to left by the transfer belt 62.

[0037] As the material moves from right to left, small-diameter materials are first screened by the first screening section 611 on the right side of the upper filter belt 61, and then fall from the filter holes of the first screening section 611 on the upper filter belt 61 onto the discharge mechanism 7.

[0038] As the material moves from the first screening section 611 on the right to the second screening section 612 on the left, the medium-sized material is screened by the filter holes on the second screening section 612 and falls into the three-stage crushing box 4. After being crushed by the three-stage crushing box 4, it falls onto the discharge mechanism 7 for discharge.

[0039] Finally, the remaining large-diameter material on the upper filter belt 61 is pushed into the secondary crushing box 3.

[0040] Large-diameter materials are crushed into small and medium-diameter materials (mainly medium-diameter materials, with a small portion of small-diameter materials) by the secondary crushing chamber 3. Both small and medium-diameter materials fall onto the filter belt 61 directly below the secondary crushing chamber 3. The small-diameter materials are first screened by the filter holes of the third screening section 613 of the filter belt 61 and fall directly onto the discharge mechanism 7 below for discharge. Then, the medium-diameter materials are pushed into the tertiary crushing chamber 4 for further crushing, finally forming small-diameter materials which fall onto the discharge mechanism 7 below for discharge.

[0041] See Figures 3-6 The transfer belt 62 includes two main conveyor belts 621 symmetrically distributed front and rear. The two main conveyor belts 621 are symmetrically arranged on the front and rear sides of the corresponding filter belt 61. Multiple pusher plates 622 are evenly arranged between the two main conveyor belts 621 along their length direction. The pusher plates 622 are vertically attached to the corresponding filter belt 61. Transfer rollers 623 are sleeved at both ends of the two conveyor belts. The two ends of the transfer rollers 623 are rotatably connected to the front and rear inner side walls of the regeneration box 1, respectively. Two transfer motors are fixedly arranged vertically on the front side of the regeneration box 1. The output shaft of the transfer motor is fixedly connected to the rear end of one of the transfer rollers 623 at the same horizontal position.

[0042] The transfer motor drives two conveyor belts to move, thereby causing their respective pusher plates 622 to move along the surface of the corresponding filter belt 61. The upper conveyor belt drives the corresponding pusher plate 622 to move from right to left, and the lower conveyor belt drives the corresponding pusher plate 622 to move from left to right.

[0043] See Figures 3-6 To reduce the risk of clogging of the filter belt 61, a winding assembly 9 is provided at both the front and rear ends of the filter belt 61. Back-blowing assemblies 10 are provided at both the front and rear ends of the filter belt 61 inside the regeneration box 1. The filter belt 61 moves and changes position in the front-back direction through the winding assembly 9 and is back-blown by the back-blowing assembly 10 to blow out the material that may be blocked in the filter holes on the surface of the filter belt 61. In addition, collection boxes 11 for collecting clogging material are installed on the bottom front and rear side walls inside the regeneration box 1. The material in the collection box 11 is cleaned regularly.

[0044] See Figure 3 and Figure 4 The winding assembly 9 includes three guide rollers 91 and one winding roller 92 rotatably disposed between the left and right inner walls of the recycling box 1. The three guide rollers 91 and the winding roller 92 are rectangularly distributed. One end of the filter belt 61 is fixedly connected to the winding roller 92 and sequentially sleeved on the three corresponding guide rollers 91. The same end of the two winding rollers 92 connected to the same filter belt 61 is connected by a pulley group for transmission. Two winding motors are fixedly disposed on the left side of the recycling box 1. The output shaft of the winding motor is connected to one end of the corresponding winding roller 92.

[0045] Taking the upper filter belt 61 as an example, when the winding motor rotates forward, the left winding roller 92 winds up the upper filter belt 61 from one end, while the right winding roller 92 unwinds it. This causes the filter belt 61, which was originally in the working area, to be guided to the left by the left guide roller 91. The back-blowing component 10 set on the left side then blows out the material that may be blocked in its filter holes. At the same time, the idle area on the right side of the filter belt 61 is switched to the working area, thereby further extending the maintenance cycle of the equipment.

[0046] See Figure 3 and Figure 4 The backflush assembly 10 includes a hollow air distribution plate 101 fixedly disposed between the left and right inner walls of the regeneration box 1. The hollow air distribution plate 101 is provided with backflush nozzles 102 evenly distributed along its length on the side near the back of the corresponding filter belt 61. The hollow air distribution plate 101 is connected to an external air source device through an air supply pipe to supply high-pressure gas.

[0047] In summary, the various crushing chambers are positioned at different locations within the recycling chamber 1 from top to bottom. They are connected to the primary crushing chamber 2 and the secondary crushing chamber 3 via two sets of screening and conveying mechanisms 6. This allows materials of different particle sizes produced in the primary and secondary crushing chambers 2 and 3 to be conveyed to the next-stage crushing chamber 2 or the discharge mechanism 7 after each crushing operation. This significantly reduces material waste caused by over-crushing of qualified rubber granules, improving the quality of the produced recycled rubber granules. Furthermore, it reduces the crushing pressure on each crushing mechanism 5, increases the efficiency of each crushing mechanism 5 in handling large and medium-sized materials that truly require crushing, and also reduces wear on the crushing mechanism 5 to some extent, extending its maintenance time.
