The invention relates to a method and a device for adjusting and controlling temperature of circulating air flow in a fluidized bed. The outer surface of a centrifugal fan is cooled by circulating cooling water or low-temperature fresh air, and the interior of the centrifugal fan is cooled by the circulating cooling water or the low-temperature fresh air; a water cooling fan mechanism is positioned in the center, and a cooling water supply mechanism, a cooling air supply mechanism and a temperature adjusting and controlling mechanism are arranged around a water cooling fan mechanism. The device and the method have the advantages that on the basis of not changing the layout of a cigarette machine, by adopting the method of combining circulating cooling water and low-temperature fresh air, the condensate is removed, so as to adjust and control the temperature of circulating air flow in the fluidized bed to 30-37 DEG C; the temperature of circulating air flow in the fluidized bed can be well adjusted and controlled, and the functions of temperature monitoring and automatic adjusting are realized; in the adjusting and control process, the system adopts an automatic operating mode, the shutdown is not needed, the requirements of high-grade cigarette making technology are met, and the taste and smoking of cigarette can be improved.
Description
technical field [0001] The invention relates to a cigarette making machine which supplies filaments in a fluidized bed mode, in particular to a method and device for controlling the temperature of circulating air flow inside the fluidized bed, which belongs to the technical field of tobacco machinery equipment. Background technique [0002] The wide application of the fluidized bed in the cigarette making machine greatly reduces the shredded tobacco rate and improves the quality of the cigarette. Its working principle is as follows: a centrifugal fan is used as the intermediate carrier, and the air inlet of the fan is connected with the fluidized bed and the filter to form a cavity , the air outlet of the fan is connected to the air distribution box, and the air distribution box distributes the circulating airflow to the fluidized bed airflow nozzle and the primary and secondary sorting airflow nozzles, thereby forming an airflow circulation system. Through this circulating a...
