Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of drying equipment, and particularly relates to a drying device for the production of nitrile rubber. Background Art
[0002] As an important synthetic rubber, nitrile rubber is widely used in many fields such as industrial production and daily life, and can be used to manufacture various products such as automotive parts, sealing products, and rubber hoses. During the production process of nitrile rubber, due to process requirements or raw material characteristics, it often contains a certain amount of moisture. If not removed in time, it will have a serious impact on the performance and quality of the rubber, such as reducing the strength and flexibility of the rubber and shortening its service life. Therefore, drying has become one of the key links in the production of nitrile rubber.
[0003] In actual production, nitrile rubber is often processed in granular form, and these granules are mostly recycled and reprocessed from various waste rubbers, such as waste rubber, rubber scraps, automotive cushion tapes, and automotive tires. Due to the complex sources, these rubber granules are prone to adsorb moisture during the collection, transportation, and storage processes, further increasing the necessity of drying.
[0004] However, there are many problems with existing nitrile rubber drying equipment. On the one hand, traditional drying devices usually can only dry one side of the rubber granules, and this one-sided drying method causes uneven heating of the granules, making it difficult for some granules to be fully dried, thus affecting the overall drying effect. On the other hand, during drying, the rubber granules often pile up together, which not only hinders the full contact between the hot air and the granules, reduces the heat transfer efficiency, prolongs the drying time, but also easily causes some granules to not be dried due to long-term piling up, resulting in incomplete drying.
[0005] Therefore, it is necessary to provide a drying device for the production of nitrile rubber to solve the above technical problems. Summary of the Invention

[0041] A carding assembly 3, the carding assembly 3 is arranged on the top of the conveying assembly 1, the carding assembly 3 includes a fixed frame 31, a mounting frame 32, a mounting bracket 33, a second driving motor 331, a driving gear 34, a driven gear 35, a turntable 36, a moving rod 37, a carding rod 38 and a carding groove 39, the mounting frame 32 is fixedly installed at one end of the fixed frame 31, the mounting bracket 33 is fixedly installed at the bottom of the mounting frame 32, the second driving motor 331 is fixedly installed at the bottom of the mounting bracket 33, the driving gear 34 is fixedly installed at the output end of the second driving motor 331, the driven gears 35 are respectively meshed on both sides of the driving gear 34, the turntable 36 is fixedly installed on the top of the driven gear 35, one end of the moving rod 37 is rotatably connected to the top of the turntable 36, and the carding rod 38 is fixedly installed at the bottom of the moving rod 37.
[0042] The conveying assembly 1 includes a conveying frame 11, a first driving motor 12, a rotating shaft 13, a conveyor belt 14, side skirts 15 and through holes 16, the rotating shafts 13 are respectively arranged at both ends of the inner side of the conveying frame 11, the conveyor belt 14 is sleeved on the outer sides of the two rotating shafts 13, the through holes 16 are opened on the surface of the conveyor belt 14, the side skirts 15 are respectively fixedly installed on both sides of the outer side of the conveyor belt 14, the output end of the first driving motor 12 and one end of a rotating shaft 13 are fixedly installed, and the first driving motor 12 is also fixedly installed on one side of the conveying frame 11.
[0043] The carding groove 39 is formed inside the fixed frame 31. The moving rod 37 is arranged on the inner side surface of the carding groove 39, and the carding rod 38 is arranged at the bottom of the carding groove 39.
[0044] The bottom of the carding rod 38 is arranged on the top of the conveyor belt 14.
[0045] Both sides of the conveying frame 11 are provided with first mounting grooves 4, and the bottom frame 21 is fixedly installed on the inner side surface of the first mounting groove 4.
[0046] Both sides of the bottom frame 21 are provided with second mounting grooves 5, and the fixed frame 31 is fixedly installed on the inner side surface of the second mounting groove 5.
[0047] The bottom frame 21 and the top frame 22 are respectively arranged at the bottom and the top of the conveyor belt 14.
[0048] The conveying frame 11 serves as the main frame of the conveying component, providing an installation foundation for other components. Its sturdy structure ensures the stability of the device during operation. The first driving motor 12 is the power source of the conveying component. When it starts, the output power drives the connected rotating shaft 13 to rotate, causing the conveyor belt 14 sleeved on the outer side surface of the rotating shaft 13 to start running. The side skirts 15 provided on the conveyor belt 14 can effectively prevent the nitrile rubber particles from falling off from both sides of the conveyor belt during transportation, ensuring the integrity of the material transportation. Through the arrangement of the through holes 16, during the drying process, hot air can pass through these through holes 16 and blow the nitrile rubber particles from below the conveyor belt 14, realizing the all-round drying of the particles, greatly improving the drying efficiency and effect.
[0049] The drying component 2 is the core part for drying nitrile rubber. The bottom frame 21 and the top frame 22 cooperate with each other to construct a relatively enclosed drying space. The top frame 22 is fixedly installed on the top of the bottom frame 21, forming a stable structural framework. The heating fan 23 is installed on the top of the top frame 22, and it is the key equipment for generating hot air. When the heating fan 23 is started, electrical energy is converted into heat energy to generate high-temperature hot air. These hot air enters the ventilation frame 25 through the pipeline. The ventilation frames 25 are respectively installed on both sides of the inner sides of the bottom frame 21 and the top frame 22, playing a role in evenly distributing the hot air. The air pipe 24 connects the upper and lower ventilation frames 25, enabling the hot air to circulate in the entire drying space. The blowing pipe 26 is fixedly installed in the middle of the two ventilation frames 25, directly blowing the hot air onto the nitrile rubber particles on the conveyor belt 14. The filter plate 27 is installed on one side of the blowing pipe 26, and its function is to filter the impurities that may be carried in the hot air, preventing these impurities from adhering to the nitrile rubber particles and affecting the product quality. Through such a design, the drying component can blow and dry the particles on the conveyor belt from above and below simultaneously, achieving an all-round drying effect. Compared with the traditional method of simply drying by the fan blades, the drying time is greatly shortened.
[0050] The mounting frame 33 is fixed to the bottom of the mounting frame 32. The second drive motor 331 is installed at the bottom of the mounting frame 33, providing power for the combing component. When the second drive motor 331 is started, the driving gear 34 at its output end rotates accordingly. The driving gear 34 meshes with the driven gears 35 on both sides, driving the driven gears 35 to rotate. The turntable 36 is fixedly installed on the top of the driven gear 35 and rotates with the rotation of the driven gear 35. One end of the moving rod 37 is rotatably connected to the top of the turntable 36, and the other end slides in the combing groove 39. When the turntable 36 rotates, one end of the moving rod 37 makes a circular motion, and the other end, under the restriction of the combing groove 39, makes the combing rod 38 perform a reciprocating motion on the top of the conveyor belt 14. The bottom of the combing rod 38 contacts the nitrile rubber particles on the conveyor belt 14. During the reciprocating motion, the particles are combed, making the particle distribution more uniform. In this way, the contact area between the particles and the hot air increases, and the hot air can act on the particles more fully, effectively avoiding the phenomenon of incomplete drying and improving the drying quality.
[0051] The working principle of a drying device for nitrile rubber production provided by the present invention is as follows:
[0052] First, start the first driving motor 12. The first driving motor 12 drives the rotating shaft 13 to rotate, causing the conveyor belt 14 to start running. Place the nitrile rubber particles on the conveyor belt 14. As the conveyor belt 14 moves, the particles enter the drying area. At the same time, start the heating blower 23. The hot air generated by the heating blower 23 enters the ventilation frame 25 through the pipeline, and then the gas is blown through the air pipe 24 into the interior of the upper and lower ventilation frames 25, and then blown onto the nitrile rubber particles on the conveyor belt 14 through the air blowing pipe 26. And through the upper and lower air blowing pipes 26, the nitrile rubber particles on the conveyor belt 14 can be blown from above and below simultaneously. The hot air penetrates through the through holes on the surface of the conveyor belt 14 to dry the particles in all directions. During the drying process, start the second driving motor 331. The second driving motor 331 drives the driving gear 34 to rotate, the driving gear 34 drives the driven gears 35 on both sides to rotate, and the driven gears 35 drive the turntable 36 to rotate. When the turntable 36 rotates, one end of the moving rod 37 makes a circular motion driven by the turntable 36, and the other end slides in the combing groove 39, so that the combing rod 38 makes a reciprocating motion on the top of the conveyor belt 14 to comb the nitrile rubber particles, making the particles more evenly distributed, increasing the contact area with the hot air, and improving the drying effect.
[0053] Compared with the related technology, a drying device for nitrile rubber production provided by the present invention has the following
[0054] Beneficial effects:
[0055] Through the cooperation of structures such as the conveying component 1 and the drying component 2, when in use, the hot air generated by the heating blower 23 can blow and dry the particles on the conveyor belt 14 from above and below simultaneously through the air pipe 24, the ventilation frame 25 and the air blowing pipe 26, realizing all-round drying of the particles and increasing the drying effect;
[0056] Through the combing component 3 to comb the nitrile rubber particles during the drying process, the second driving motor 331 drives the driving gear 34 to rotate, and then drives the driven gears 35 and the turntable 36 to rotate, driving the combing rod 38 to make a reciprocating motion on the top of the conveyor belt 14, making the particles more evenly distributed. In this way, the contact area between the particles and the hot air is increased, allowing the hot air to act on the particles more fully, effectively avoiding the phenomenon of incomplete drying, and improving the drying quality.

[0062] When in use, the shielding components 6 are respectively installed at both ends of the top frame 22. At this time, the hanging shielding strips 62 can block the openings at both ends of the bottom frame 21, thereby preventing the hot air generated by the heating fan 23 from quickly escaping.

[0064] Beneficial effects:
[0065] By respectively installing the shielding components 6 at both ends of the top frame 22, the openings at both ends of the bottom frame 21 are shielded, preventing the rapid loss of hot air, thereby increasing the effect of drying nitrile rubber.
