Description

Technical Field

[0001] This utility model relates to the technical field of recycled rubber processing equipment, and in particular to an energy-saving desulfurization machine for recycled rubber specifically designed for basketball bladders. Background Technology

[0002] After being discarded, rubber products such as basketball bladders have high recycling value due to the high value of their main material, recycled rubber. Through desulfurization processes, the vulcanized cross-linked structure of waste rubber can be broken down, restoring its plasticity and processing properties, thereby achieving resource recycling.

[0003] Existing desulfurization processes are typically carried out in sealed rubber desulfurizers, using mechanical stirring and heating to promote the desulfurization reaction. However, the recycled rubber used in basketball bladders exhibits high viscosity and strong adhesion during desulfurization, especially under high temperature and shear stress.

[0004] This high viscosity of the material causes it to easily adhere to the inner wall of the desulfurizer body and the bottom stirring device, forming a coking layer that is difficult to clean. This not only affects the heat transfer efficiency and the effective volume of the equipment, but also reduces the quality of the final product.

[0005] More seriously, when desulfurization is complete and material needs to be discharged, these poorly flowing and easily sticky rubber materials are prone to accumulating and caking as they pass through the relatively small-diameter discharge pipe. As material continues to be discharged, the blockage inside the discharge pipe rapidly worsens, eventually leading to a complete blockage of the discharge channel and forcing production to stop. Operators must then spend a significant amount of time manually clearing the blockage, which is not only inefficient but also poses certain safety hazards.

[0006] Therefore, this utility model proposes a desulfurization machine for recycled rubber specifically for basketball bladders to address the shortcomings of existing technologies. Utility Model Content

It also addresses the problem that processed materials easily accumulate and clog at the discharge pipe, leading to poor discharge.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a desulfurization machine for recycled rubber specifically for basketball bladders, comprising: a rubber desulfurization machine body, an inlet pipe, an outlet pipe, a first motor, a rotating column, a propeller blade, a cleaning component, and an anti-clogging component.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-4 This utility model provides a desulfurization machine for recycled rubber specifically for basketball bladders, aiming to solve the problem in the prior art where rubber materials easily adhere to the inner wall of the equipment and the inside of the discharge pipe during processing, causing cleaning difficulties, poor discharge, or even blockage, thereby affecting production efficiency and product quality.

[0022] Specifically, it includes a rubber desulfurizer body 1 and a first motor 6 fixedly connected above the rubber desulfurizer body 1. The rubber desulfurizer body 1 serves as a support platform and reaction vessel for the entire desulfurization equipment. The first motor 6 drives the internal core components to rotate, providing power for the desulfurization process of the rubber material.

[0023] It also includes a cleaning component 3 and an anti-clogging component 2. The top of the rubber desulfurizer body 1 is provided with a feed pipe 4 for adding the rubber material to be processed into the interior of the rubber desulfurizer body 1. The bottom of the rubber desulfurizer body 1 is connected to a discharge pipe 5 for discharging the processed rubber material.

[0024] The main body 1 of the rubber desulfurizer has a rotating column 7 installed inside, which is vertically arranged along the central axis of the main body 1. The top of the rotating column 7 is rotatably connected to the output shaft of the first motor 6, and the first motor 6 drives the rotating column 7 to rotate through the output shaft. The lower end of the rotating column 7 is fixedly connected to a propeller blade 8. When the rotating column 7 rotates, the propeller blade 8 stirs, mixes, and shears the rubber material inside the main body 1 of the rubber desulfurizer, thereby realizing the desulfurization process of the rubber.

[0025] The cleaning component 3 is installed inside the rubber desulfurizer body 1 and is used to clean the rubber material adhering to the inner wall and bottom of the rubber desulfurizer body 1. The cleaning component 3 includes a first connecting rod 301, a first scraper 302, a second connecting rod 303, and a second scraper 304.

[0026] The first connecting rod 301 is fixedly connected to the upper middle part of the rotating column 7. The first scraper 302 is fixedly connected to the outer end of the first connecting rod 301, and the outer wall of the first scraper 302 is in close contact with the inner wall of the rubber desulfurizer body 1. When the rotating column 7 rotates, the first connecting rod 301 drives the first scraper 302 to rotate synchronously, and the first scraper 302 scrapes the inner wall of the rubber desulfurizer body 1, scraping off the rubber material attached thereto.

[0027] The second connecting rod 303 is fixedly connected to the lower part of the rotating column 7, located below the first connecting rod 301. The second scraper 304 is fixedly connected to the outer end of the second connecting rod 303, and the outer wall of the second scraper 304 is in close contact with the inner bottom wall of the rubber desulfurizer body 1. Similarly, when the rotating column 7 rotates, the second connecting rod 303 drives the second scraper 304 to rotate synchronously. The second scraper 304 scrapes the inner bottom wall of the rubber desulfurizer body 1, scraping off the rubber material attached thereto, ensuring that the bottom is clean.

[0028] The anti-clogging component 2 is located outside the discharge pipe 5 to prevent the processed rubber material from clogging inside the discharge pipe 5. The anti-clogging component 2 includes a second motor 201, a rotating rod 203, a first gear 204, a second gear 205, and a stirring rod 206.

[0029] The second motor 201 is fixedly connected to the outer wall of the discharge pipe 5 via a retaining ring 202. The output shaft of the second motor 201 is rotatably connected to the top end of the rotating rod 203 and drives the rotating rod 203 to rotate. The rotating rod 203 extends downward in the vertical direction.

[0030] The first gear 204 is fixedly connected to the bottom end of the rotating rod 203. The second gear 205 is located inside the bottom of the discharge pipe 5 and meshes with the first gear 204. When the first gear 204 rotates, it drives the second gear 205 to rotate synchronously through meshing.

[0031] The stirring rod 206 is fixedly connected to the inner wall of the second gear 205 and extends into the discharge pipe 5. When the second gear 205 rotates, the stirring rod 206 rotates in a circular motion inside the discharge pipe 5, continuously agitating the rubber material inside the discharge pipe 5, effectively preventing the rubber material from accumulating and solidifying inside the discharge pipe 5 and causing blockage, thereby ensuring smooth discharge.

[0032] The rotating column 7 is arranged along the axis of the rubber desulfurizer body 1, ensuring the symmetry and uniformity of stirring and cleaning. At the same time, both the feed pipe 4 and the discharge pipe 5 are equipped with opening and closing valves to facilitate the control of material entry and exit, prevent leakage or backflow of material during non-operation periods, and improve the convenience and safety of operation.

[0033] Both the first scraper 302 and the second scraper 304 are made of flexible materials, such as rubber, silicone, or soft plastic. The flexible material scrapers can better conform to the curved surfaces of the inner wall and bottom inner wall of the rubber desulfurizer body 1. Even if there are slight unevennesses in the inner wall, they can ensure effective scraping while avoiding scratching the inner wall of the equipment and extending the service life of the equipment.

[0034] A sealing structure is provided at the connection between the second motor 201 and the outer wall of the discharge pipe 5. This sealing structure can take the form of a sealing gasket, O-ring, or lip seal, which effectively prevents the gas or liquid generated during the desulfurization process from leaking from the connection. It also prevents external dust or impurities from entering the transmission mechanism of the second motor 201, protecting the motor and gear transmission components from contamination and damage, and improving the stability and durability of the equipment.

[0035] The stirring rod 206 has a circular cross-sectional shape. A circular cross-section results in more uniform agitation of the rubber material during rotation, with relatively lower resistance, helping to prevent localized overheating or excessive shearing of the material. The circular cross-section also reduces the risk of material adhesion, further enhancing the anti-clogging effect.

[0036] The fixing ring 202 adopts a clamp structure. The clamp structure can easily and firmly fix the second motor 201 to the outer wall of the discharge pipe 5, and can be quickly and conveniently disassembled and installed when maintenance or replacement of the second motor 201 is required, which simplifies the equipment maintenance process and reduces maintenance costs.

[0037] The bottom of the rubber desulfurization machine body 1 is fixedly connected to the ground. The fixed connection can be achieved by using anchor bolts, welding, or gravity anchoring, etc., to ensure that the entire desulfurization equipment can maintain a high degree of stability and safety during operation, especially during high-speed stirring and scraping, to prevent the equipment from shifting or overturning due to vibration, and to ensure the safety of operators.

[0038] Working principle: First, the material is added into the body 1 of the rubber desulfurizer through the feed pipe 4. Then, the first motor 6 is started, which drives the rotating column 7 to rotate clockwise. Then, the rotation of the rotating column 7 drives the propeller blade 8 to rotate, thereby processing the rubber material. Then, the cleaning component 3 prevents the rubber material from adhering to the inner wall of the rubber desulfurizer body 1. Then, the processed rubber is discharged through the discharge pipe 5. Finally, the anti-blocking component 2 prevents the rubber from causing blockage inside the discharge pipe 5. To prevent blockage inside the discharge pipe 5, the second motor 201 is first started. The second motor 201 is fixed to the outer wall of the discharge pipe 5 by the fixing ring 202. Then, the second motor 201 drives the rotating rod 203 to rotate clockwise. Next, the rotation of the rotating rod 203 drives the first gear 204 to rotate synchronously. Then, the rotation of the first gear 204 drives the second gear 205 to rotate at the bottom of the discharge pipe 5. Next, the rotation of the second gear 205 drives the stirring rod 206 to rotate circumferentially on the inner wall of the discharge pipe 5. The stirring rod 206 is fixed to the inner wall of the second gear 205, thereby preventing the rubber from causing blockage inside the discharge pipe 5. When cleaning the inner wall of the rubber desulfurizer body 1, the rotation of the rotating column 7 first drives the first connecting rod 301 to rotate synchronously. Then, the rotation of the first connecting rod 301 drives the first scraper 302 to rotate. The outer wall of the first scraper 302 is in contact with the inner wall of the rubber desulfurizer body 1, thereby scraping off the rubber attached to the inner wall of the rubber desulfurizer body 1. Then, the rotation of the rotating column 7 drives the second connecting rod 303 to rotate synchronously. Then, the rotation of the second connecting rod 303 drives the second scraper 304 to rotate. The outer wall of the second scraper 304 is in contact with the bottom inner wall of the rubber desulfurizer body 1, thereby scraping off the rubber attached to the bottom inner wall of the rubber desulfurizer body 1.
