Description

Technical Field

[0001] This utility model relates to the field of reclaimed rubber production technology, specifically to a reclaimed rubber batching and conveying production equipment. Background Technology

[0002] With the increasing scale of the rubber product industry, such as tires, inner tubes, and conveyor belts, the consumption of reclaimed rubber is rapidly increasing. Developing and expanding the reclaimed rubber industry and making full use of rubber resources can not only reduce the environmental pollution caused by waste rubber, but also alleviate the shortage of natural and synthetic rubber in my country.

[0003] During the production of reclaimed rubber, the temperature rise caused by heating and stirring generates a large amount of dust, smoke, and pungent odor. Therefore, a large amount of waste gas containing volatile organic pollutants is also generated when conveying desulfurized rubber compounds. Subsequent refining processes also generate a large amount of waste gas. Although there are specialized waste gas treatment and purification devices to collect and treat the waste gas, the treatment of the escaping waste gas still needs improvement. Currently, tubular augers or tubular chain conveyors are mostly used for cooling and conveying rubber compounds after mixing and discharging. However, long-distance tubular augers are prone to rubber blockage during conveying, while tubular chain conveyors have disadvantages such as complex structure, high energy consumption when unloaded, high manufacturing cost, and poor cooling effect, which are not conducive to the smooth conveying of rubber compounds. In addition, the amount of rubber compound fed into the conveying system needs to be controlled to avoid the possibility of empty running or overflow. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects in waste gas treatment and rubber material transportation in the prior art, thereby providing a recycled rubber batching and transportation production equipment.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A recycled rubber batching and conveying production equipment includes a batching device, a mixing device, a feeding device, and a production device arranged sequentially along the material conveying direction. The batching device includes a weighing component and a pneumatic conveyor. The weighing component is a batching hopper with a weighing sensor at the bottom. The batching hopper is connected to the pneumatic conveyor and conveys material to the mixing device. The mixing device includes a mixing tank and an isolation enclosure. The mixing tank is installed inside the isolation enclosure, and its bottom is connected to the feeding device. The feeding device includes a feeding component and a feeding element. One end of the feeding component is connected to the mixing tank and... The other end is connected to a feeding device, which is connected to a production unit. The production unit includes at least two refining machines arranged in sequence and at least one filter. The filter is located at the end of the refining machine away from the feeding device. It also includes a purification device, which is connected to a mixing device and the production unit. The purification device includes a mixing exhaust gas device, an escaping flue gas device, a refining exhaust gas device, and an emission device. The mixing exhaust gas device and the escaping flue gas device are both installed at the mixing device and connected to the emission device. The refining exhaust gas device is installed at the refining machine and connected to the emission device.

[0007] By adopting the above technical solutions, a feeding device is added to the initial section of the original long-distance conveying of rubber material. The feeding device controls the amount of rubber material fed into the conveying device, reducing the possibility of material overflow and avoiding idling. A cooling water jacket covers the outside of the conveying device to control and cool the conveyed rubber material. All conveying devices adopt U-shaped cylinders to facilitate cleaning in case of blockage, ensuring smooth conveying. A mixing exhaust gas device, an escaping flue gas device, and a refining exhaust gas device are set up to collect and treat the large volume of exhaust gas and escaping flue gas during the conveying and production process, ensuring complete purification of exhaust gas and reducing environmental pollution.

[0008] Furthermore, the mixing tank includes a tank body, a feeding cylinder, and a discharge cover. The feeding cylinder has a vertical axis and is installed on the top of the tank body. An exhaust cover is hinged above the feeding cylinder and controlled by an opening and closing drive. Pressure sensors connected to the opening and closing drive and the mixing exhaust gas device are installed inside the tank body. A mixing device is also rotatably installed inside the tank body. The mixing device includes a mixing rod and multiple mixing blades. The mixing rod is arranged along the length of the tank body and its axis is perpendicular to the axis of the feeding cylinder. The mixing blades are mounted on the mixing rod. A feeding device extends from the feeding cylinder and is provided with a feeding port, a water inlet, and a feeding outlet. A discharge outlet is opened at the bottom of the tank body. The discharge cover is hinged at the bottom of the tank body and corresponds to the discharge outlet. The discharge cover is controlled by a discharge drive. A feeding device is correspondingly provided below the discharge outlet.

[0009] By adopting the above technical solution, the mixing tank automatically adds water, softener and activator through the feeding device, and then mixes and heats. After reaching a certain pressure through the pressure sensor, the exhaust cover is automatically opened to exhaust gas, ensuring stable pressure in the mixing tank and effective treatment of waste gas. The mixed material is discharged from the bottom discharge port and then fed back through the feeding device. Both the exhaust cover and the discharge cover are remotely and automatically opened and closed by corresponding opening and closing drive components, avoiding safety hazards caused by manual operation.

[0010] Furthermore, the feeding component is installed inside the isolation cover. The feeding component includes a feeding cylinder, a feeding spiral section, and a feeding hopper. The feeding cylinder is cylindrical and is arranged along the length of the mixing tank. The feeding spiral section is rotatably installed inside the feeding cylinder, and the axis of the feeding spiral section is parallel to the axis of the feeding cylinder. The feeding hopper is installed above the end of the feeding cylinder near the discharge port and is arranged corresponding to the discharge port.

[0011] By adopting the above technical solution, a feeding component with a short spiral section is set in front of the feeding component. On the one hand, it can receive the direct drop of material at the discharge port and avoid direct impact on the front end of the long feeding component. On the other hand, it can control the amount of material fed and achieve precise control of the feeding quantity.

[0012] Furthermore, the top of the feeding hopper is inclined, and the end of the top of the feeding hopper near the hinge axis between the discharge cover and the tank body is lower than the end away from the hinge axis. The feeding hopper also has guide components on opposite sides. Each guide component includes a guide drive, a guide slide rod, a guide chute frame, and a lifting slide rod. One end of the guide slide rod is controlled to rotate by the guide drive, and the other end slides within the guide chute frame. The guide chute frame is arranged along the length of the top of the feeding hopper. The lifting slide rod is perpendicular to the guide chute frame and extends above the middle of the top edge of the guide chute frame. A locking slider extends from the outer wall of the feeding hopper corresponding to the lifting slide rod. An installation rod connects the lifting slide rods on both sides. An array of punching rods with axes perpendicular to the installation rod is arranged on the installation rod. The end of the feeding cylinder away from the discharge port is connected to the feeding component.

[0013] By adopting the above technical solution, a guide component is added at the discharge port. The guide rod agitates the discharge port and the feeding hopper below, thus avoiding blockage of the discharge port or unsmooth material feeding at the feeding hopper.

[0014] Furthermore, the feeding component includes two interconnected conveying sections and a lifting section. One end of the conveying section is connected to the feeding cylinder and the other end is connected to the lifting section. The axis of the conveying section is perpendicular to the axis of the feeding cylinder. The conveying section is horizontally positioned and located below the ground. The axis of the lifting section is parallel to the axis of the conveying section. The lifting section is located at the end of the conveying section away from the feeding component. The lifting section is inclined, and the height of the end closer to the conveying section is lower than the height of the end away from the conveying section.

[0015] By adopting the above technical solution, the conveying section of the feeding component is similar to a screw extruder. Desulfurization is carried out in the conveying section, and then the material is lifted and conveyed by the lifting section to the storage device for temporary sealed storage, waiting for subsequent quantitative production.

[0016] Furthermore, the conveying section includes an upward-opening U-shaped conveying cylinder, a conveying spiral section, and a conveying cover. The axis of the conveying spiral section is arranged along the length of the conveying cylinder and is rotatably installed inside the conveying cylinder. The conveying cover is located at the opening of the conveying cylinder and is bolted to the conveying cylinder. The conveying cover also has multiple exhaust ports, and an exhaust pipe extends from the exhaust ports. A vacuum pressing device is installed inside the exhaust pipe, and the exhaust pipe is also connected to a stirring exhaust gas component. The lifting section includes an upward-opening U-shaped lifting cylinder, a lifting spiral section, and a lifting cover. The lifting spiral section is arranged along the length of the lifting cylinder and is rotatably installed inside the lifting cylinder. The lifting cover is located at the opening of the lifting cylinder and is bolted to the lifting cylinder.

[0017] By adopting the above technical solution, the rubber compound is conveyed and desulfurized in the conveying section. In order to ensure smooth conveying and stable internal pressure, an exhaust port is set for exhaust. The exhaust port does not come into direct contact with the air and the rubber compound is prevented from leaking from the exhaust port by a vacuum pressing device. The exhaust pipe is connected to the agitator to treat the exhaust gas of the conveyed rubber compound, ensuring environmental safety and reducing pollution.

[0018] Furthermore, both the conveying cylinder and the lifting cylinder are fitted with U-shaped cooling water jackets, which are arranged along the length of the corresponding conveying cylinder and the lifting cylinder. Both ends of the top opening of the conveying cylinder and the lifting cylinder are fitted with channel steel with openings facing away from each other. The conveying cylinder and the lifting cylinder are respectively fixed to the conveying cover and the lifting cover by the corresponding channel steel.

[0019] By adopting the above technical solution, the structure of the U-shaped cooling water jacket matching the conveying cylinder and the lifting cylinder facilitates heat exchange and cooling of the conveyed rubber material; the channel steel strengthens the outer top of both the conveying cylinder and the lifting cylinder and matches the conveying cover and the lifting cover, which facilitates the installation of the conveying cover and the lifting cover and avoids directly drilling holes in the conveying cylinder and the lifting cylinder, which would affect their structural strength.

[0020] Furthermore, a storage device is provided in front of the production device. The storage device includes a storage bin and a discharge component. The inlet of the storage bin is connected to the end of the lifting cylinder. An inclined discharge component is provided below the outlet of the storage bin. The height of the end of the discharge component near the storage bin is lower than the height of the end away from the storage bin. The discharge component includes a discharge cylinder and a discharge spiral section. The discharge spiral section is arranged along the length of the discharge cylinder and is rotatably installed in the discharge cylinder. The end of the discharge cylinder has a discharge port connected to the refining machine.

[0021] By adopting the above technical solution, the rubber material fed by the feeding component is not used directly in production. The rubber material is first stored in the storage silo, and then discharged for production according to production performance and efficiency. The storage silo is set up to seal the material storage to reduce the contact between the desulfurized rubber material and oxygen, thus ensuring the quality of subsequent production.

[0022] Furthermore, both the stirring exhaust gas component and the refining exhaust gas component are connected to the treatment component. The treatment component is located at the front end of the emission component and includes an alkaline washing component, a four-stage filter component, a rotary concentrator component, and an RTO incineration structure. The stirring exhaust gas component includes an extraction pipeline and an incineration component. The isolation hood is installed outside the stirring tank, and the extraction pipeline is installed on the top of the isolation hood and corresponds to the exhaust cover. The refining exhaust gas component includes a gas collecting hood and an oil removal component. The gas collecting hood is located corresponding to the refining machine and above the top of the refining machine. The oil removal component is installed between the gas collecting hood and the treatment component, and the oil removal component is an electrostatic oil removal structure.

[0023] By adopting the above technical solution, the stirring exhaust gas component collects a large volume of stirring and heating exhaust gas, and the refining exhaust gas component collects the exhaust gas produced during refining. After collection, both are uniformly introduced into the treatment component for collection and treatment.

[0024] Furthermore, the flue gas component includes a collection pipe and a purification component. One end of the collection pipe is connected to the isolation hood and the other end is connected to the purification component. The purification component includes a water washing structure and a UV photocatalytic structure. The end of the purification component away from the collection pipe is also connected to the emission component.

[0025] By adopting the above technical solution, an escape flue gas device is added to the original waste gas treatment system to collect and purify the escape flue gas during the production process of the mixing tank. The escape flue gas is then collected, purified, and then discharged into the emission device.

[0026] In summary, the technical solution of this utility model has the following advantages:

[0027] 1. The recycled rubber batching and conveying production equipment provided by this utility model adds a feeding component to the initial section of the original long-distance conveying of rubber material.

[0039] 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.

[0040] A reclaimed rubber batching and conveying production equipment, such as Figure 1 and Figure 2As shown, the device includes a batching device 1, a mixing device 2, a feeding device 3, and a production device 6. These components are arranged sequentially along the material conveying direction. The batching device 1 includes a weighing component 11 and a pneumatic conveyor 12. The weighing component 11 is a batching bin 111 with a weighing sensor at the bottom. The batching bin 111 is connected to the pneumatic conveyor 12 and conveys materials to the mixing device 2. The mixing device 2 includes a mixing tank 21 and an isolation enclosure 22. The mixing tank 21 is installed inside the isolation enclosure 22, and its bottom is connected to the feeding device 3. The feeding device 3 includes a feeding component 4 and a feeding component 5. One end of the feeding component 4 is connected to the mixing tank 21, and the other end is connected to the feeding component 5. The feeding component 5 is connected to the production device 6. The production device 6 includes at least two refining machines 61 arranged sequentially and at least one filter 62. The filter 62 is located at the end of the refining machine 61 furthest from the feeding device 3. In this application, multiple batching bins 111 and mixing tanks 21 can be set according to production needs. The number of feeding components 4 corresponds to the number of mixing tanks 21, and multiple feeding components 4 can be fed into the same feeding component 5. By adding feeding components 4 to the initial section of the original long-distance conveying of rubber material, the feeding components 4 control the amount of rubber material fed into the feeding component 5, reducing the possibility of material overflow and avoiding empty feeding.

[0041] It also includes a purification device 8, which is connected to the mixing device 2 and the production device 6. The purification device 8 includes a mixing exhaust gas component 81, a fume extraction component 82, a refining exhaust gas component 83, and an emission component 84. The mixing exhaust gas component 81 and the fume extraction component 82 are both installed at the mixing device 2 and connected to the emission component 84, while the refining exhaust gas component 83 is installed at the refining machine 61 and connected to the emission component 84. The mixing exhaust gas component 81, the fume extraction component 82, and the refining exhaust gas component 83 are set up to collect and treat the large volume of exhaust gas and fume extraction gas during the conveying and production processes, ensuring complete purification of the exhaust gas and reducing environmental pollution.

[0042] like Figure 1 , Figure 2 and Figure 3As shown, both the stirring exhaust gas component 81 and the refining exhaust gas component 83 are connected to the treatment component 85. The treatment component 85 is located at the front end of the discharge component 84. The treatment component 85 includes an alkaline washing component 851, a four-stage filter component 852, a rotary concentrator component 853, and an RTO incineration structure 854. The stirring exhaust gas component 81 includes an extraction pipe 811 and an incineration component 812. The isolation hood 22 is installed outside the stirring tank 21. The extraction pipe 811 is installed on the top of the isolation hood 22 and is set corresponding to the exhaust cover 213. The refining exhaust gas component 83 includes a gas collecting hood 831 and an oil removal component 832. The gas collecting hood 831 is set corresponding to the refining machine 61 and is located above the top of the refining machine 61. The oil removal component 832 is installed between the gas collecting hood 831 and the treatment component 85. The oil removal component 832 is an electrostatic oil removal structure. The stirring exhaust gas unit 81 collects a large volume of stirring and heating exhaust gas, and the refining exhaust gas unit 83 collects the refining production exhaust gas. Both are then fed into the treatment unit 85 for collection and treatment. The stirring tank 21 automatically opens to exhaust gas after stirring and heating to the required pressure. The stirring exhaust gas unit 81 collects a large volume of stirring exhaust gas and sends it to the incineration unit 812 for incineration at 750°C. After incineration, the exhaust gas is sent to the alkaline washing unit 851 for alkaline washing. The alkaline-washed exhaust gas undergoes multi-stage filtration through the four-stage filter unit 852 and is concentrated at the rotary concentrator unit 853 before being sent to the RTO incineration structure 854 for further incineration. Finally, it is sent to the emission unit 84 for discharge. The refining exhaust gas is drawn in and collected by the gas collection hood 831 and electrostatically degreased before being sent to the treatment unit 85 for treatment, ensuring complete purification of the production exhaust gas.

[0043] The fugitive gas collection component 82 includes a collection pipe 821 and a purification component 822. One end of the collection pipe 821 is connected to the isolation hood 22, and the other end is connected to the purification component 822. Multiple collection pipes 821 can be installed to collect fugitive gas from multiple angles. The purification component 822 includes a water washing structure 8221 and a UV photocatalytic structure 8222. The collected fugitive gas is first subjected to alkaline washing and demisting at the water washing structure 8221, and then the gas is sent to the UV photocatalytic structure 8222 for deodorization and purification. The end of the purification component 822 away from the collection pipe 821 is also connected to the emission component 84. The fugitive gas collection component 82 is added to the existing waste gas treatment system to collect and purify the fugitive gas during the production process of the mixing tank 21. After collection and purification, the fugitive gas is then introduced into the emission component 84. When the mixing waste gas component 81 is working, the fugitive gas collection component 82 is shut off to prevent large volumes of high-concentration waste gas from being discharged into the emission component 84 without proper treatment.

[0044] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the conveying cover 513 is also provided with multiple exhaust ports 5131, and an exhaust pipe 5132 extends from the exhaust port 5131. A vacuum pressing device 5133 is installed inside the exhaust pipe 5132. The vacuum pressing device 5133 is prior art and will not be described in detail in this application. The exhaust pipe 5132 is also connected to the mixing exhaust gas component 81. The rubber material is conveyed and desulfurized in the conveying section 51. In order to ensure smooth conveying and stable internal pressure, the exhaust port 5131 is set for exhaust. The exhaust port 5131 does not directly contact the air and the vacuum pressing device 5133 prevents the rubber material from leaking from the exhaust port 5131. The exhaust pipe 5132 is connected to the mixing exhaust gas component 81 to treat the exhaust gas of the conveyed rubber material, ensuring environmental safety and reducing pollution.

[0045] like Figure 2 , Figure 3 and Figure 4 As shown, the mixing tank 21 includes a tank body 211, a feeding cylinder 212, and a discharge cover 214. The feeding cylinder 212 has a vertical axis and is installed on the top of the tank body 211. Pressure sensors connected to the opening and closing drive component 2131 and the stirring exhaust component 81 are installed inside the tank body 211. The pressure sensors detect the pressure inside the tank body 211, facilitating timely pressure relief and exhaust, and reducing safety accidents. A stirring component 2112 is also rotatably installed inside the tank body 211. The stirring component 2112 includes a stirring rod 21121 and multiple stirring blades 21122. The stirring rod 21121 is arranged along the length of the tank body 211 and its axis is perpendicular to the axis of the feeding cylinder 212. The stirring blades 21122 are mounted on the stirring rod 21121. A feeding component 2121 extends from the feeding cylinder 212. The feeding component 2121 is equipped with a feeding port 21211, a water inlet 21212, and a feeding port 21213. The mixing tank 21 automatically adds water, softener, and activator through the feeding component 2121, and then stirs and heats. After reaching a certain pressure, the exhaust cover 213 is automatically opened to exhaust gas to ensure stable pressure in the mixing tank 21 and effective treatment of waste gas.

[0046] An exhaust cover 213 is hinged to the top of the feeding cylinder 212. The exhaust cover 213 is controlled by an opening and closing drive component 2131. A discharge port 2111 is opened at the bottom of the tank body 211. A discharge cover 214 is hinged to the bottom of the tank body 211 and corresponds to the discharge port 2111. The discharge cover 214 is controlled by a discharge drive component. A feeding component 4 is correspondingly arranged below the discharge port 2111. The mixed adhesive is discharged from the bottom discharge port 2111 and then fed again by the feeding component 4. Both the exhaust cover 213 and the discharge cover 214 are remotely and automatically opened and closed by corresponding opening and closing drive components 2131 and discharge drive components, avoiding safety hazards caused by manual operation.

[0047] like Figure 2 , Figure 3 and Figure 4As shown, the feeding component 4 is installed inside the isolation cover 22. The feeding component 4 includes a feeding cylinder 41, a feeding spiral section 42, and a feeding hopper 43. The feeding cylinder 41 is cylindrical and arranged along the length of the mixing tank 21. The end of the feeding cylinder 41 away from the discharge port 2111 is connected to the feeding component 5. The feeding spiral section 42 is rotatably installed inside the feeding cylinder 41, and the axis of the feeding spiral section 42 is parallel to the axis of the feeding cylinder 41. A driving component is connected to the feeding spiral section 42 to drive its rotation. The feeding hopper 43 is installed above the end of the feeding cylinder 41 near the discharge port 2111 and is arranged corresponding to the discharge port 2111. The top of the feeding hopper 43 is inclined. The height of the end of the top of the feeding hopper 43 near the hinge axis between the discharge cover 214 and the tank 211 is lower than the height of the end away from the hinge axis between the discharge cover 214 and the tank 211. In the figure, the height on the left side is lower than the height on the right side. A short spiral section of the feeding component 4 is set in front of the feeding component 5. On the one hand, it receives the direct material falling from the discharge port 2111, avoiding direct impact on the front end of the long feeding component 5. On the other hand, it can control the amount of material fed, and achieve precise control of the feeding quantity.

[0048] like Figure 3 and Figure 4 As shown, the feeding hopper 43 is also provided with guide members 44 on both sides. Each guide member 44 includes a guide drive member 441, a guide slide rod 442, a guide chute frame 443, and a lifting slide rod 444. One end of the guide slide rod 442 is controlled to rotate by the guide drive member 441, and the other end is slidably disposed in the guide chute frame 443. The guide chute frame 443 is arranged along the length of the top of the feeding hopper 43. The lifting slide rod 444 is arranged perpendicular to the guide chute frame 443 and extends into the guide slide rod 443. Above the center of the top edge of the trough frame 443, a locking slider 431 is provided on the outer wall of the feeding hopper 43 corresponding to the lifting slide rod 444. An installation rod 445 is also connected between the lifting slide rods 444 on both sides. A poking rod 446 with an axis perpendicular to the installation rod 445 is arranged in an array on the installation rod 445. A guide component 44 is added at the discharge port 7211. The guide rod poks the discharge port 7211 and the feeding hopper 43 below to avoid the discharge port 7211 from being blocked or the material from the feeding hopper 43 from not discharging smoothly.

[0049] The output shaft of the guide drive 441 rotates, causing one end of the guide slide rod 442 to rotate and the other end to slide within the guide chute frame 443. The guide chute frame 443 and the lifting slide rod 444 are fixedly connected, and the position of the lifting slide rod 444 is limited by the locking slider 431 extending from the feeding hopper 43. Therefore, the guide chute frame 443, the lifting slide rod 444, the guide slide rod 442, and the locking slider 431 constitute a crank-slider motion. The lifting slide rod 444 is raised and lowered within the locking slider 431. Since the guide chute frame 443 moves along the feeding hopper 43, the lifting slide rod 444, the guide slide rod 442, and the locking slider 431 constitute a crank-slider motion. The top of the hopper 43 is positioned along its length, and the lifting slide bar 444 is perpendicular to the guide slide frame 443. Therefore, the lifting slide bar 444 moves up and down in a direction perpendicular to the guide slide frame 443. A mounting rod 445 is connected between the two lifting slide bars 444. The mounting rod 445 moves with the lifting slide bar 444. A vertical chuck 446 is provided on the mounting rod 445. When the mounting rod 445 moves, it reciprocates to chuck the top discharge port 7211 and the bottom feeding hopper 43, which facilitates the top discharge and bottom unloading operations.

[0050] When the discharge cover 214 is to be opened, the guide drive component 441 controls the lifting slide bar 444 to slide to the bottom. At this time, the piercing rod 446 is located on the right side inside the feeding hopper 43 and avoids the opening trajectory of the discharge cover 214, so as not to affect the opening and closing operation of the discharge cover 214. After the discharge cover 214 is fully opened, it is located on the right side of the feeding hopper 43, and the discharge cover 214 will not cause structural interference with the guide component 44.

[0051] like Figure 2 , Figure 5 and Figure 6 As shown, the feeding unit 5 includes two interconnected conveying sections 51 and lifting sections 52. One end of the conveying section 51 is connected to the feeding cylinder 41, and the other end is connected to the lifting section 52. The axis of the conveying section 51 is perpendicular to the axis of the feeding cylinder 41. The conveying section 51 is horizontally positioned and located below the ground. The axis of the lifting section 52 is parallel to the axis of the conveying section 51. The lifting section 52 is located at the end of the conveying section 51 away from the feeding unit 4. The lifting section 52 is inclined, and the height of the end closer to the conveying section 51 is lower than the height of the end away from the conveying section 51. The conveying section 51 in the feeding unit 5 is similar to a screw extruder. Desulfurization is performed in the conveying section 51, and the material is then lifted and conveyed by the lifting section 52 to the storage device 7 for temporary sealed storage, awaiting subsequent quantitative production.

[0052] The conveying section 51 includes an upward-facing U-shaped conveying cylinder 511, a conveying spiral section 512, and a conveying cover 513. The axis of the conveying spiral section 512 is arranged along the length of the conveying cylinder 511 and is rotatably installed inside the conveying cylinder 511. One end of the conveying spiral section 512 is provided with a driving component to drive its rotation. The conveying cover 513 is located at the top opening of the conveying cylinder 511 and is fixed to the conveying cylinder 511 by multiple standard bolts.

[0053] The lifting section 52 includes an upward-facing U-shaped lifting cylinder 521, a lifting spiral section 522, and a lifting cover 523. The lifting spiral section 522 is positioned and rotatably installed inside the lifting cylinder 521 along the length of the lifting cylinder 521. The lifting spiral section 522 is inclined and the height of the left end is lower than the height of the right end. The lifting cover 523 is located at the upper opening of the lifting cylinder 521 and is fixed to the lifting cylinder 521 by multiple bolts.

[0054] like Figure 5 and Figure 6 As shown, both the conveying cylinder 511 and the lifting cylinder 521 are fitted with U-shaped cooling water jackets 53. The cooling water jackets 53 are arranged along the length of the corresponding conveying cylinder 511 and the lifting cylinder 521. The length of the cooling water jacket 53 is less than the length of the corresponding conveying cylinder 511 and the lifting cylinder 521. Both ends of the top opening of the conveying cylinder 511 and the lifting cylinder 521 are equipped with channel steels 54 with openings facing away from each other. The conveying cylinder 511 and the lifting cylinder 521 are respectively installed and fixed to the conveying cover 513 and the lifting cover 523 through the corresponding channel steels 54. During the spiral feeding process of the feeding component 5, the structure of the U-shaped cooling water jackets 53 matching the conveying cylinder 511 and the lifting cylinder 521 facilitates heat exchange and cooling of the conveyed rubber material, and the temperature of the material drops from 150℃ to 60-70℃. The channel steel 54 provides structural reinforcement to the outer top of both the conveying cylinder 511 and the lifting cylinder 521 and is designed to fit with the conveying cover 513 and the lifting cover 523. This facilitates the installation of the conveying cover 513 and the lifting cover 523 and avoids directly drilling holes in the conveying cylinder 511 and the lifting cylinder 521, which would affect their structural strength.

[0055] like Figure 5 and Figure 6 As shown, a storage device 7 is also provided in front of the production device 6. The storage device 7 includes a storage bin 71 and a discharge component 72. The inlet of the storage bin 71 is connected to the end of the lifting cylinder 521. An inclined discharge component 72 is provided below the outlet of the storage bin 71. The height of the end of the discharge component 72 near the storage bin 71 is lower than the height of the end away from the storage bin 71. The discharge component 72 includes a discharge cylinder 721 and a discharge spiral section 722. The discharge spiral section 722 is arranged along the length of the discharge cylinder 721 and is rotatably installed inside the discharge cylinder 721. The spiral at the front end of the discharge spiral section 722 is denser than that at the rear end. The discharge outlet 7211 is provided at the end of the discharge cylinder 721 and is connected to the refining machine 61. The rubber material delivered by the feeding component 5 is not used directly in production. It is first stored in the storage silo 71, and then discharged for production based on production performance and efficiency. The storage silo 71 is sealed to reduce the contact between the desulfurized rubber material and oxygen, thus ensuring the quality of subsequent production.

[0056] Working principle and usage of this recycled rubber batching and conveying production equipment:

[0057] Mixing and mixing: The formula is set and the rubber material is weighed and fed through the mixing hopper 111. The rubber material is sent to the mixing tank 21 through the negative pressure air conveyor 12. Water, softener and activator are automatically added and the mixing unit 2112 is started to mix and heat the rubber material. After the mixing tank 21 reaches a certain pressure, the exhaust cover 213 is automatically opened to release pressure and exhaust gas. At the same time as the cover is opened, the mixing exhaust gas unit 81 is started to treat the exhaust gas.

[0058] Feeding and molding: The mixed rubber material is discharged from the bottom discharge port 2111, first fed into the feeding component 4 and then fed into the feeding component 5 by spiral feeding, and cooled during the feeding process. The conveyed material is sent into the storage bin 71 for sealed storage, and subsequently refined by at least two refining machines 61 and filtered by one filter machine 62 as required before molding.

[0059] Waste gas treatment: The stirring waste gas component 81 extracts and discharges the waste gas after the stirring tank 21 is opened; the refining waste gas component 83 treats and discharges the refining waste gas during the refining production process; and the escaping flue gas component 82 collects and purifies the escaping flue gas during the production process of the stirring tank 21.
