Description
Technical Field
The invention relates to a rotary dryer device, which mainly comprises a rotary hub, a transmission system and a fire box, wherein the rotary hub is driven by the transmission system to rotate, wet granular materials to be dried are arranged inside the rotary hub, and a high-temperature smoke is introduced between the outer part of the rotary hub and the fire box to heat the rotary hub and then enter the rotary hub to be fully contacted with the wet materials for heating, so that the aim of drying the wet materials is fulfilled. This have guide plate desiccator to change hub can effectively guide the high temperature flue gas that gets into between firebox and the commentaries on classics hub and flow round the commentaries on classics hub outer wall and carry out the heat exchange with commentaries on classics hub outer wall furthest, shorten the stoving time to wet material, change hub length simultaneously and also can correspondingly shorten.
Background
For many years, the rotary dryer widely used in the carbon black industry is equipment for drying wet carbon black particles to meet the process requirements, and generally, a rotary hub is within the range of 2-6 meters in diameter and 20-25 meters in length according to the capacity of processing the wet carbon black particles in various specifications. The existing rotary dryer rotary hub has no guide plate, high-temperature flue gas enters a disordered state between a fire box and the rotary hub, flue gas concentrated local pressure is large, flue gas flow surrounding the rotary hub cannot be formed due to direct flow to the tail part where the flue gas is thin, flue gas heat loss is large, heating of wet carbon black particles is affected due to uneven heating of the rotary hub, partial particles are conveyed to a discharge port when humidity of the partial particles does not meet technological requirements, the qualified rate of the dried particles is low and uneven, if the method of increasing the length of the rotary hub is adopted to increase the drying time of the wet carbon black particles in the rotary hub to meet the technological requirements, equipment manufacturing cost is high, installation is difficult, and the occupied area is large. Carry out the innovative design to desiccator rotary hub through analytical research, under the unchangeable condition of original desiccator rotary hub structure promptly, increase high temperature flue gas guide plate outside rotary hub, through leading around the rotary hub flow to flue gas stream, increase and rotary hub heat exchange time and evenly distributed to the thermal radiation that wet carbon black granule produced in the rotary hub is even unanimous, drying effect is good, the finished product qualification rate is high. The arrangement of the guide plate effectively solves the problems that the qualified rate of finished products of the drying machine is low, the high-temperature smoke outside the rotating hub is not uniformly distributed and the like. The method is characterized in that: a spiral guide plate is arranged on the outer wall of the rotating hub, and the flue gas flow is guided by the guide plate to flow around the rotating hub after entering; the contact time of the flue gas and the rotating hub is long, and the drying effect of the dryer on the materials is ensured. Compared with the original dryer, the field feedback has obvious drying effect and improves the qualification rate of finished products.
Therefore, the rotary dryer rotary hub with the smoke guide plate is developed, the high-temperature smoke flow is guided to be uniformly distributed on the rotary hub, the heat exchange between the smoke and the rotary hub is improved, and the qualified rate of finished products is improved.
Disclosure of Invention
The invention aims to develop a rotary dryer rotary hub with a smoke guide plate, and the guide plate effectively solves the problem that the qualification rate of a finished material product is low due to uneven heating of the rotary dryer rotary hub.
The technical scheme adopted by the invention is as follows:
