Description

Technical Field

[0001] This utility model belongs to the technical field of rubber production equipment, specifically, it relates to a liquid recycled rubber drying device. Background Technology

[0002] Liquid reclaimed rubber (referred to as liquid recycled rubber) is a liquid rubber product with fluidity or low viscosity obtained by using waste rubber products (such as waste tires, waste conveyor belts, waste seals, etc.) as raw materials and breaking down the cross-linking structure between the original rubber molecules through physical, chemical, or combined physical-chemical methods, thereby reducing its molecular weight and viscosity. Its core characteristics are that it retains the basic chemical structure of rubber, can be re-vulcanized and cross-linked, and is easy to process and compatible with other materials. It is mainly used in rubber product modification, adhesive preparation, coating additives, sealing materials, and other fields, realizing the high-value recycling and utilization of waste rubber.

[0003] After liquid reclaimed rubber is processed into sheets or blocks, it is cooled to form rubber. To facilitate rapid use of the formed rubber, a drying device is needed to dry the cooled rubber. For example, patent document CN217257560U discloses a functionalized liquid reclaimed rubber drying device, including a drying chamber. A fixing base is fixedly installed at the middle of the front and rear ends of the drying chamber. A pad is fitted onto the lower end of the fixing base, and a mounting seat is fixedly installed on the upper outer surface of the pad. A weighing sensor is fixedly installed inside the mounting seat. A sealing cover is fixedly installed on the upper outer surface of the drying chamber, and a speed reducer is fixedly installed at the middle of the upper end of the sealing cover. A motor is fixedly installed at the input end of the speed reducer above the sealing cover, and a connecting shaft is fixedly connected to the output end of the speed reducer inside the drying chamber. A stirring blade is fixedly installed on the outer surface of the connecting shaft. Ventilation openings are provided on both sides of the upper part of the drying chamber. This invention can improve the drying effect of the drying device and make the drying efficiency higher, thus possessing certain practicality.

[0004] However, the aforementioned drying device suffers from uneven air distribution, affecting drying efficiency, and lacks exhaust gas purification equipment, which can easily pollute the environment. Therefore, further improvements are needed. Utility Model Content
