Description

Technical Field

[0001] This utility model relates to the technical field of accessories for recycled rubber production equipment, specifically to a spiral guide plate for desulfurization of recycled rubber. Background Technology

[0002] With the continuous increase in the consumption of rubber products, the treatment and recycling of waste rubber has become an important issue for sustainable resource development. Desulfurization of recycled rubber is a key step in the recycling and reuse of waste rubber. Through desulfurization, vulcanized rubber can regain its plasticity and be reused for secondary processing.

[0003] Currently, traditional desulfurization equipment for recycled rubber mostly adopts stirred or tank-type desulfurization methods, which have problems such as low desulfurization efficiency, uneven desulfurization, and high energy consumption. In stirred desulfurization, the flow path of materials in the equipment is highly random, and some rubber cannot fully contact the desulfurizing agent; tank-type desulfurization, due to the static distribution of materials in the container, leads to insufficient desulfurization reaction and is prone to local over-desulfurization or under-desulfurization.

[0004] Existing flow guiding structures are simple in design, such as using simple inclined guide plates for flow guidance. However, they are unable to effectively guide materials to form an orderly and efficient flow path within the desulfurization equipment, making it difficult to meet the production needs of large-scale, high-quality reclaimed rubber desulfurization. Therefore, it is urgent to develop a spiral guide plate that can optimize material flow and improve desulfurization efficiency and quality for reclaimed rubber desulfurization equipment. Utility Model Content

[0005] The purpose of this invention is to provide a spiral guide plate for desulfurization of recycled rubber, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A support is fixedly installed at the center of the top surface of the top cover. A spiral guide plate in a spiral shape is arranged inside the cylinder. A rotating shaft is fixedly installed at the center of the top of the spiral guide plate. The rotating shaft passes through the support and is rotatably connected to the support. A servo motor is detachably installed at the end of the rotating shaft. Multiple guide holes are provided on the spiral guide plate. A wear-resistant alloy layer is provided at the edge of the spiral guide plate.

[0008] Preferably, a plurality of raw material pipes are fixedly installed on the top of the cylinder, and a rinsing pipe is fixedly installed on the top of the top cover;

[0009] This setup allows for material feeding via the feed pipe and rinsing via the rinse pipe.

[0010] Preferably, the spiral angle of the spiral guide plate is 45 degrees to 60 degrees, and the thickness of the wear-resistant alloy layer is between 2 mm and 3 mm.

[0011] Preferably, the diameter of the guide hole is between 5 and 8 mm, and the spacing between adjacent guide holes is between 15 mm and 20 mm.

[0012] Preferably, a support plate is provided above the cylinder, and the servo motor is detachably mounted on the support plate by multiple fastening bolts.

[0013] Preferably, a crossbeam plate is fixedly installed on the side of the support plate, and the crossbeam plate is fixedly installed on the external frame.

[0014] Preferably, a protruding post is fixedly installed at the top of the rotating shaft, and a rectangular groove is provided inside the protruding post, the top of which is connected to the outside. A rectangular rod is fixedly installed at the end of the output shaft of the servo motor, and the rectangular rod is located in the rectangular groove and is inserted into the rectangular groove.

[0015] Preferably, both the rectangular rod and the rectangular groove have rectangular cross-sections, and the dimensions of the rectangular rod are adapted to the dimensions of the rectangular groove;

[0016] The above two settings facilitate plug-in assembly operations, making loading and unloading simpler.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, by setting a spiral guide plate with a spiral angle of 45 degrees to 60 degrees, and cooperating with multiple guide holes of specific diameter and spacing on the plate, realizes the orderly flow of materials along the spiral path in the cylinder. At the same time, under the action of the guide holes, a dispersed and mixed state is formed, which prolongs the contact time between the material and the desulfurizing agent, and achieves the effect of significantly improving the desulfurization efficiency and uniformity, effectively solving the problems of low efficiency and incomplete reaction of traditional desulfurization methods.

[0019] 2. This utility model strengthens the protection of key parts of the spiral guide plate by setting a wear-resistant alloy layer with a thickness of 2mm to 3mm at the edge of the spiral guide plate, thereby improving the service life of the guide plate, reducing the frequency and cost of equipment maintenance, and ensuring the continuity of desulfurization production of recycled rubber.

[0020] 3.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Please see Figures 1-3 This utility model provides a technical solution: a spiral guide plate for desulfurization of recycled rubber, including a cylinder 1, with a top cover 11 detachably installed on the top of the cylinder 1 to prevent impurities from entering, and at the same time to facilitate opening the top cover 11 when the equipment is inspected, cleaned or replaced, making maintenance operations more convenient.

[0030] In this embodiment, a support 12 is fixedly installed at the center of the top surface of the top cover 11. A spiral guide plate 2 in a spiral shape is provided inside the cylinder 1. A rotating shaft 22 is fixedly installed at the center of the top of the spiral guide plate 2. The rotating shaft 22 passes through the support 12 and is rotatably connected to the support 12. A corresponding bearing is embedded in the support 12. The rotating shaft 22 passes through the bearing and is fixedly installed on the inner ring of the bearing, providing stable support for the rotation of the spiral guide plate 2, so that the spiral guide plate 2 remains stable when rotating, and ensuring the orderly flow of materials.

[0031] like Figure 1As shown, multiple raw material pipes 10 are fixedly installed on the top of the cylinder 1, which can realize the simultaneous or batch feeding of multiple materials, meet the requirements of different desulfurization processes for material ratio and feeding sequence, and improve feeding efficiency; a flushing pipe 13 is fixedly installed on the top of the top cover 11. After the desulfurization operation is completed, flushing liquid can be introduced to flush the inside of the cylinder 1, the spiral guide plate 2 and other components, remove residual materials in time, prevent material accumulation from affecting the next desulfurization effect, and reduce the difficulty of equipment cleaning.

[0032] like Figure 2 As shown, the spiral guide plate 2 has a spiral angle of 45 degrees to 60 degrees, which allows the material to rise along the spiral path inside the cylinder 1, prolonging the residence time of the material in the desulfurization zone and ensuring full contact with the desulfurizing agent.

[0033] like Figure 2 As shown, a servo motor 31 is detachably installed at the end of the rotating shaft 22. Multiple guide holes 20 are provided on the spiral guide plate 2. The diameter of the guide holes 20 is between 5 and 8 mm, and the spacing between adjacent guide holes 20 is between 15 mm and 20 mm. This promotes the continuous dispersion and mixing of materials during the flow process, further improving the desulfurization efficiency and uniformity, and effectively improving the shortcomings of traditional desulfurization methods.

[0034] like Figure 3 As shown, a wear-resistant alloy layer 21 is provided at the edge of the spiral guide plate 2. The thickness of the wear-resistant alloy layer 21 is between 2mm and 3mm, which greatly enhances the wear resistance of the edge of the spiral guide plate 2, resists the friction loss caused by material flow, extends the service life of the spiral guide plate 2, reduces the downtime and maintenance costs caused by frequent replacement of parts due to wear, and ensures the continuity of desulfurization production of recycled rubber.

[0035] like Figure 1 and Figure 2 As shown, a support plate 3 is provided on the top of the cylinder 1. The servo motor 31 is detachably mounted on the support plate 3 by multiple fastening bolts, providing a stable mounting platform for the servo motor 31. The detachable connection of multiple fastening bolts facilitates the installation, disassembly and maintenance of the servo motor 31. A crossbeam plate 30 is fixedly installed on the side of the support plate 3. The crossbeam plate 30 is fixedly installed on the external frame, connecting the equipment to the external structure, enhancing the overall stability of the equipment and keeping it firm during operation.

[0036] like Figure 1 and Figure 2As shown, a protruding post 23 is fixedly installed at the top of the rotating shaft 22. A rectangular groove 231 with its top connected to the outside is provided inside the protruding post 23. A rectangular rod 32 is fixedly installed at the end of the output shaft of the servo motor 31. The rectangular rod 32 is located in the rectangular groove 231 and is inserted into the rectangular groove 231. After the rectangular rod 32 is inserted into the rectangular groove 231, the rectangular rod 32 and the protruding post 23 are fixed by fastening screws. The cross-sections of the rectangular rod 32 and the rectangular groove 231 are both rectangular. The size of the rectangular rod 32 is matched with the size of the rectangular groove 231. While ensuring effective torque transmission and driving the spiral guide plate 2 to rotate, it makes the connection and disassembly of the servo motor 31 and the rotating shaft 22 easier, reduces the difficulty of equipment assembly, and facilitates the replacement and debugging of the servo motor 31 in the later stage.

[0037] When using the spiral guide plate for desulfurization of recycled rubber of this utility model, the support plate 3 is first fixed to the external frame by the crossbeam plate 30, the servo motor 31 is installed on the support plate 3 by fastening bolts, and the rectangular rod 32 at the end of the output shaft of the servo motor 31 is inserted into the rectangular groove 231 in the protrusion 23 at the top of the rotating shaft 22 to complete the connection. At the same time, the rectangular rod 32 and the protrusion 23 are fixed by fastening screws.

[0038] Subsequently, the material is fed into the cylinder 1 through the raw material pipe 10. The material can be continuously dispersed and mixed along the spiral guide plate 2 and the guide hole 20, and fully contact the desulfurizing agent to complete the desulfurization reaction. When necessary, the servo motor 31 can be started to drive the spiral guide plate 2 to rotate, so that the material is conveyed more smoothly.

[0039] After desulfurization is completed, the servo motor 31 is turned off, and flushing liquid is introduced from the flushing pipe 13 to flush the inside of the cylinder 1 and the spiral guide plate 2.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
