Description

Technical Field

[0001] The invention relates to the technical field of rubber mixing machines, in particular to a stacked type of automatic recycling and processing equipment for waste materials used in the production of rubber mixing machines. Background Art

[0002] In the rubber processing industry, stacked rubber mills are key equipment, mixing and plasticizing rubber through the coordinated extrusion and shearing action of multiple rollers. However, existing rubber mixing processes have long suffered from inefficiencies and energy waste in waste recovery and treatment, creating bottlenecks that hinder production continuity and environmental friendliness.

[0003] Traditional waste recycling methods rely on manual cleaning or simple mechanical collection, which is difficult to cope with the multi-roller and high-frequency waste output characteristics of the stacked rubber mixing mill. Manual cleaning is not only labor-intensive and inefficient, but also waste is easily scattered into the gaps of equipment, causing secondary pollution; simple collection devices are mostly single fixed structures, which cannot cover key waste-producing areas such as the gaps at both ends of the rollers. The collection rate is low, and a large amount of waste is discarded due to failure to recycle in time, resulting in waste of resources.

[0016] Compared with the existing technology, it has the following beneficial effects:

[0017] 1. The waste recovery rack adopts an upper and lower stacking design, and the synergistic effect of the scraper plate and the material guide groove can fully cover the key waste-producing areas such as the gaps at both ends of the roller, greatly improving the collection rate. Compared with the collection rate of traditional equipment, it greatly reduces the scattering and abandonment of waste. The sealed connection design of the sealing mounting plate and the material guide pipe effectively avoids the leakage of waste during transportation, reduces the risk of environmental pollution in the workshop, and reduces the cost of manual cleaning. It greatly shortens the time taken to recover waste in a single rubber mixing operation. The modular recovery rack structure can be flexibly adjusted according to the rubber mixing machine model, enhancing the versatility of the equipment and adapting to the waste recovery needs of stacked rubber mixing machines of different specifications.

[0018] 2. The spiral flow channel in the heat exchange frame forms a stable insulation layer through nitrogen circulation, which reduces the heat loss rate of the roller and ensures the uniformity of rubber compound mixing. The waste heat of the roller is efficiently recovered to the waste treatment link through the nitrogen circulation system. The high-temperature nitrogen is used to heat and soften the waste in the treatment sleeve, which reduces the energy consumption of waste crushing. This solves the double loss problem of waste heat and additional energy consumption of traditional equipment. The nitrogen recycling design further reduces energy and medium consumption, further reduces the overall energy consumption of the equipment, and brings significant energy-saving benefits to the enterprise.

[0019] 3. Through the coordinated work of the crushing fixed frame and the circulating turning rack, a circulating crushing mechanism is formed in the processing sleeve for the waste. The waste that does not meet the standards can be continuously turned over and re-enter the crushing area, ensuring that the crushing qualification rate is improved and avoiding the accumulation and rework problems of the traditional single crushing mode. The coordinated design of the screen and the inclined guide rack realizes the automatic screening and concentration of the waste after crushing. Combined with the controllable discharge of the movable closing plate, the degree of automation of waste processing is greatly improved, and the single processing efficiency is significantly improved. In addition, the drive motor synchronously drives the crushing knife roller and the circulating turning rack through gear transmission, which simplifies the equipment structure, reduces the occurrence rate of failures, and improves the reliability of long-term operation.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figures 1 to 11As shown, an automatic recycling and processing equipment for waste used in the production of a stacked rubber mixing mill is provided, comprising a recycling and processing device 2 mounted on the roller of the stacked rubber mixing mill 1; the recycling and processing device 2 comprises a plurality of waste recycling racks 3 and a waste processing rack 9, wherein the plurality of waste recycling racks 3 are respectively arranged on the outer peripheral surface of the roller of the stacked rubber mixing mill 1, and a waste processing rack 9 is further provided on the rear side of the stacked rubber mixing mill 1; the waste recycling rack 3 is composed of two symmetrically arranged mounting racks, and the upper and lower mounting racks are fixedly connected by bolts; the top and bottom of the waste recycling rack 3 are fixedly connected to the bracket of the stacked rubber mixing mill 1 by bolts, and both sides of the top and bottom of the waste recycling rack 3 are fixedly provided with a material guide pipe 4, and the waste recycling rack 3 is fixedly provided with a material guide pipe 4. Material guide grooves 5 are provided on both sides of the interior of the frame 3, and the interiors of the material guide grooves 5 on both sides are respectively connected to the interiors of the material guide pipes 4 on both sides; scraper plates 10 are fixedly provided on both sides of the lower interior of the waste recovery frame 3, and one side of the two scraper plates 10 is in sliding contact with the two ends of the roller in the stacked rubber mixing machine 1; the material guide grooves 5 on both sides are respectively provided directly below the gaps at both ends of the roller in the stacked rubber mixing machine 1, and the scraper plates 10 on both sides are used to scrape off the waste discharged from the gaps at both ends of the roller. Sealing mounting plates are also provided on both sides of the waste recovery frame 3, wherein the sealing mounting plates are also divided into two parts, and the sealing mounting plates of the upper and lower parts are fixedly connected to the mounting frames of the upper and lower parts by bolts.

[0036] It should be noted that by setting the material guide groove 5 just below the gap at both ends of the roller and using the scraper 10 to directly scrape off the waste, the waste squeezed out of the roller gap can be captured at the first time to prevent it from scattering to other parts of the equipment, and the collection efficiency is significantly improved.

[0037] Furthermore, several waste recovery racks 3 are stacked up and down on the outer peripheral surface of the roller in the stacked rubber mixing machine 1, and the material guide pipes 4 on both sides of the bottom of the waste recovery rack 3 at the top are sealed with the material guide pipes 4 on both sides of the top of the waste recovery rack 3 at the bottom; both sides of the top of the waste recovery rack 3 at the top are closed, and both sides of the bottom of the waste recovery rack 3 at the bottom are fixedly provided with collecting pipes 6, and a suction pump 7 is also provided on the rear side of the waste recovery rack 3, and the feed end of the suction pump 7 is connected to one end of the collecting pipe 6, and the discharge end of the suction pump 7 is fixedly provided with a feeding pipe 8, and one end of the feeding pipe 8 is fixedly connected to one side of the waste processing rack 9.

[0038] Specifically, several waste recovery racks 3 are stacked up and down to form a continuous collection network that can cover the entire outer circumference of the roller. For the situation where multiple rollers work together in a stacked rubber mixing mill, this structure can collect waste from rollers at different positions at the same time, thereby achieving all-round waste interception; the sealing mounting plates on both sides of the waste recovery rack 3 are connected by bolts in an upper and lower manner to ensure the sealing of the entire collection system, which effectively prevents waste from leaking from the side during the collection process, reduces pollution to the production environment, and also avoids waste waste.

[0039] The waste recovery rack 3 consists of two symmetrically arranged mounting racks, which are fixedly connected by bolts. This modular design makes the installation and disassembly of the equipment very convenient. During the installation of the equipment, the number and position of the waste recovery racks 3 can be flexibly adjusted according to the specific structure and size of the rubber mixer; when maintaining the equipment, a certain recovery rack can be disassembled separately for inspection or replacement of parts without affecting the normal operation of other parts, which greatly improves the maintainability of the equipment; since the waste recovery rack 3 adopts a modular design, it can be customized according to different models and specifications of stacked rubber mixers. Only the size and connection method of the mounting rack need to be appropriately modified. The recycling and processing equipment can be applied to various types of rubber mixers, and it has strong versatility and adaptability.

[0040] Furthermore, adjacent waste recovery racks 3 are sealed and connected by a material guide pipe 4 to form a vertical waste conveying channel. The waste collected by the waste recovery rack 3 above can fall directly into the recovery rack below through the material guide pipe 4, and finally be concentrated in the collection pipe 6 at the bottom. The entire conveying process does not require complicated mechanical transmission and can be achieved by gravity. It has a simple structure and reliable operation. The setting of the suction pump 7 provides additional power guarantee for waste transportation. When the waste encounters resistance during transportation or needs to overcome a certain height difference, the suction pump 7 can ensure that the waste passes through the feed pipe 8 smoothly into the waste treatment rack 9, avoiding the problem of waste accumulation and blockage in the pipeline, and ensuring the continuity of the entire recycling and processing process.

[0041] In addition to the sealing mounting plates on both sides, the sealed connection between the material guide pipes 4 and the sealing design of the material guide interfaces 13 between the heat exchange racks 11 ensure the sealing of the entire system, which not only prevents waste leakage and heat loss, but also prevents external dust, water vapor and other impurities from entering the equipment and causing damage to the rollers and other components, thereby extending the service life of the equipment; the structural design of the entire recycling and processing equipment is reasonable, the connection between the various components is tight and reliable, the sliding contact between the scraper plate 10 and the roller can stably scrape off the waste, the power transmission of the suction pump 7 ensures the smooth flow of the waste, and the insulation structure of the heat exchange rack 11 can also play its role effectively for a long time. These factors together ensure the stable operation of the equipment, reduce the probability of failure, and improve production efficiency.

[0042] It should be noted that the waste scraped from several waste recovery racks 3 is collected centrally through the feed end of the suction pump 7 in cooperation with the collection pipe 6, and the waste discharged from both ends of the roller is scraped by the scraper plates 10 inside several waste recovery racks 3. Then, the waste is sent to the bottom waste recovery rack 3 by using the material guide grooves 5 on both sides of the interior of several waste recovery racks 3. Finally, the collected waste is sent to the interior of the waste processing rack 9 for further processing by using the cooperation of the collection pipe 6, the suction pump 7 and the feeding pipe 8.

[0043] As a further explanation of the scheme in this embodiment, heat exchange racks 11 are fixedly installed on the upper and lower parts of the waste recovery rack 3, and a number of spiral partitions 12 are fixedly installed inside the two heat exchange racks 11. A spiral heat exchange flow channel is formed inside the heat exchange rack 11 through the several spiral partitions 12. By introducing nitrogen into the spiral heat exchange flow channel, it can effectively keep the roller warm during heating, thereby greatly improving the temperature uniformity of the roller. Several material guide interfaces 13 are provided on opposite sides of the upper and lower heat exchange frames 11, and the upper and lower material guide interfaces 13 are sealed and connected; specifically, several material guide interfaces 13 with through grooves are provided at the bottom of the upper heat exchange frame 11, and several convex material guide interfaces 13 that match the through grooves are provided on the top of the lower heat exchange frame 11. Through the material guide interfaces 13 between the upper and lower heat exchange frames 11, a complete spiral heat exchange flow channel is formed between the two heat exchange frames 11. The spiral heat exchange flow channel is used to cover the surface of the roller as a whole, and nitrogen is filled in the interior of the spiral heat exchange flow channel, so that a stable insulation structure can be formed for the roller during the processing process.

[0044] It should be noted that the spiral partition 12 inside the heat exchange frame 11 forms a spiral heat exchange flow channel. This design extends the flow path of nitrogen on the roller surface, increases the contact time and contact area between nitrogen and the roller, thereby improving the thermal insulation effect. When nitrogen flows in the spiral flow channel, it can more evenly absorb and transfer the heat emitted by the roller, reduce local temperature differences, and effectively improve the temperature uniformity of the roller; the upper and lower heat exchange frames 11 are connected by a material guide interface 13 to form a complete coating structure, which tightly wraps the roller. This all-round coating design minimizes the heat exchange between the roller and the external environment, further enhances the thermal insulation performance, reduces energy consumption, and improves the energy utilization efficiency of the rubber mixer.

The waste after crushing falls onto the top of the screen 19, and the crushed waste is screened by the screen 19. The waste that meets the mesh size of the screen 19 passes through the screen 19 and falls into the bottom of the waste processing frame 9, completing the crushing of the waste. There are movable closing plates sliding up and down inside the two discharge ports 21. When the waste is crushed, the movable closing plates are controlled to close the inside of the discharge ports 21. When the crushed waste inside the waste processing frame 9 is discharged, the waste inside the waste processing frame 9 is discharged through the discharge port 21 by sliding the movable closing plates upward.

[0047] Furthermore, a circulating turning rack 25 is rotatably provided inside the processing sleeve 18, and the inner side of the circulating turning rack 25 is in sliding contact with the outer peripheral surface of the crushing fixed frame 23, and the outer side of the circulating turning rack 25 is in sliding contact with the inner wall of the processing sleeve 18; a transmission inner gear ring 26 is also fixedly provided on one side of the circulating turning rack 25, and one side of the transmission inner gear ring 26 extends to the outside of the processing sleeve 18, and a transmission gear 27 is rotatably provided on the back side of the inner wall of the waste processing frame 9, and the tooth surface of the transmission gear 27 is meshed with the inner teeth of the transmission inner gear ring 26 for transmission.

[0048] Furthermore, a drive frame 22 is fixedly provided on the back of the waste processing frame 9, one end of the two crushing knife rollers 24 extends to the interior of the drive frame 22, and the two crushing knife rollers 24 are respectively fixed with a driving gear 28 and a driven gear 29 at one end inside the drive frame 22; a rotating shaft is fixedly provided inside the transmission gear 27, and one end of the rotating shaft extends to the interior of the drive frame 22, and a driven gear 2 30 is also fixedly provided at one end of the rotating shaft inside the drive frame 22, and the tooth surface of the driving gear 28 is respectively meshed with the tooth surface of the driven gear 1 29 and the driven gear 2 30 for transmission; a driving motor 31 is fixedly provided on the back of the driving frame 22, and the output shaft of the driving motor 31 is fixedly connected to one end of the driving gear 28 through a coupling.

[0049] The waste is then fed back into the hopper 24 and the hopper 26 is fed back into the hopper 26, which is fed back into the hopper 26, and the hopper 27 is fed back into the hopper 26, which is fed back into the hopper 26, and the hopper 26 ...

[0050] Furthermore, a circulating air supply pipe 14 and a circulating air exhaust pipe 15 are fixedly provided on both sides of the back of several waste recovery racks 3, and the interior of the circulating air supply pipe 14 is connected to one side of the interior of the heat exchange rack 11 through a conduit, and the interior of the circulating air exhaust pipe 15 is connected to the other side of the interior of the heat exchange rack 11 through a conduit; a circulating air pump 16 is fixedly provided on the top of the waste processing rack 9, and the air exhaust end of the circulating air pump 16 is connected to the interior of the processing sleeve 18, and the air supply end of the circulating air pump 16 is connected to the interior of the circulating air supply pipe 14; one end of the circulating air exhaust pipe 15 extends to the top of the waste processing rack 9, and the circulating air exhaust pipe 15 is located on one side of the top of the waste processing rack 9 and is connected to the interior of the processing sleeve 18 through several air guide pipes 17.

[0051] It should be noted that when recycling waste materials, nitrogen is circulated and filled into the heat exchange racks 11 inside the plurality of waste recovery racks 3 via the circulating air pump 16. The specific operation is as follows: nitrogen is filled into the interior of the circulating air supply pipe 14, and the circulating air pump 16 is used to circulate the nitrogen into the interior of the plurality of heat exchange racks 11, thereby utilizing the heat exchange racks 11 to improve the temperature uniformity of the rollers during the processing. After the rubber mixing operation is completed using the stacked rubber mixing mill 1, the nitrogen inside the heat exchange racks 11 is pumped into the processing sleeve 18 via the circulating air pump 16, and the residual heat of the rollers is replaced by the circulating nitrogen. The nitrogen that has absorbed the residual heat of the rollers is then fed into the processing sleeve 18, and the waste inside the processing sleeve 18 is heated by the heated nitrogen, thereby further improving the waste treatment effect.

[0052] Example 3

[0053] Specifically, this embodiment also discloses a workflow method of a stacked type rubber mixing mill production waste automatic recycling and processing device, as follows:

[0054] According to the number and size of rollers of the stacked rubber mixing mill 1, several waste recovery racks 3 are stacked and assembled by bolting the upper and lower mounting racks to ensure that the material guide pipes 4 of adjacent recovery racks are sealed and connected, the top of the uppermost recovery rack is closed, and the bottom of the lowermost recovery rack is connected to the collection pipe 6. At the same time, check the sealing of the sealing mounting plate, the fit between the scraper plate 10 and the two ends of the roller, and the rotation flexibility of the crushing knife roller 24 and the circulating turning rack 25 in the waste processing rack 9.

[0055] Start the circulating air pump 16 and introduce nitrogen into the heat exchange racks 11 in all waste recovery racks 3 through the circulating air supply pipe 14. The nitrogen flows along the spiral flow channel formed by the spiral partition 12. The upper and lower heat exchange racks 11 are sealed and connected through the material guide interface 13 to form a flow channel that completely covers the roller. The low thermal conductivity of nitrogen is used to pre-insulate the roller, so that the roller temperature gradually tends to be uniform and is preheated to the temperature required for rubber mixing, 50-120°C.

[0056] The stacked rubber mixing machine 1 is started, and the rollers rotate to perform the rubber mixing operation. The rubber is squeezed out from the gaps at both ends of the rollers to form waste. The scrapers 10 on both sides of the waste recovery frame 3 slide in contact with both ends of the rollers, scraping the waste into the material guide groove 5 in real time. The sealing mounting plate prevents the waste from leaking from the side, ensuring that all the waste enters the material guide groove.

[0057] The waste in the material guide trough 5 falls by gravity, enters the waste recovery rack below in turn through the material guide pipe 4 connected above and below, and finally converges to the collection pipe 6 of the lowest recovery rack. The extraction pump 7 is started, and the concentrated waste is pumped into the feeding pipe 8 through the collection pipe 6, and continuously transported to the processing sleeve 18 of the waste processing rack 9. The circulating air pump 16 keeps the nitrogen circulating in the heat exchange rack 11. The spiral flow channel prolongs the contact time between the nitrogen and the roller, maintains the temperature uniformity of the roller, and avoids the impact of local temperature fluctuations on the rubber mixing quality.

[0058] The feed pipe 8 feeds the waste into the top of the crushing fixed frame 23, and the drive motor 31 is started, and the driven gear 1 29 is driven by the driving gear 28, so that the two crushing rollers 24 rotate relative to each other in the crushing fixed frame 23 to shear and crush the waste. At the same time, the driving gear 28 drives the driven gear 2 30, and through the engagement of the transmission gear 27 and the transmission inner gear ring 26, the circulating turning frame 25 is driven to rotate in the processing sleeve 18, turning over the waste retained above the screen 19 and pushing it back into the crushing fixed frame 23 to achieve circulating crushing.

[0059] The crushed waste falls into the screen 19, and the waste that meets the mesh size passes through the screen and enters the bottom of the waste processing rack 9, and is guided to both sides by the inclined guide rack 20. At this time, the movable closing plate of the discharge port 21 is in a closed state, temporarily storing the screened waste.

[0060] After the rubber mixing operation is completed, the circulating air pump 16 switches the working mode and extracts the nitrogen that has absorbed the residual heat of the roller in the heat exchange frame 11 through the circulating exhaust pipe 15, and sends it into the processing sleeve 18 through the air guide pipe 17. The high-temperature nitrogen heats the waste in the processing sleeve and uses the residual heat to soften the waste, thereby helping to improve the crushing efficiency.

[0061] The nitrogen in the processing sleeve 18 is re-sent into the circulating air supply pipe 14 through the circulating air pump 16 to complete the nitrogen circulation. The movable closing plates on both sides of the waste processing rack 9 are opened, and the screened waste is discharged through the discharge port 21 for subsequent processing.

[0062] Stop all equipment operation, dismantle the upper and lower mounting frames of the waste recovery rack 3, clean the residual waste in the material guide trough 5 and the material guide pipe 4; open the processing sleeve 18, clean the impurities on the crushing knife roller 24 and the screen 19 to ensure smooth operation next time.
