The SDT gas pipeline type cut tobacco drying machine is important component equipment in the tobacco making process, and has the main functions of using superheated steam as a drying medium to quickly dehydrate, dry and shape cut stems, removing miscellaneous gas and wood gas in tobacco stems, and meeting the comprehensive performance requirements of a cigarette process on the softness, filling value, moisture precision and the like of the cut stems.

After the process is finished, three components of the tobacco stalk material, namely the tobacco stalk material, the dust and the impurity gas are separated by a material separator, the separated material is produced in the next process, and the impurity gas is exhausted to the atmosphere through an air purification device. The dust enters the feed hopper from the upper end of the feed hopper II, then passes through the dust removal airlock seal cavity, and then enters the dust collection barrel to be discharged.

The cyclone dust collector in the main structure is used for removing dust in process gas, the dust is discharged through a dust removal air lock below the cyclone dust collector, the lower part of the dust removal air lock is connected with a dust collection cylinder, the dust collection cylinder is provided with an observation window, and the dust is timely dumped by an operator after accumulating to a certain amount.

Because production grades are numerous, the difference of technological requirements such as temperature and humidity among the grades is large, in the production process of some grades, the humidity is large, dust is easy to stick on an airlock blade rotor when being discharged through a dedusting airlock, the phenomenon of blockage of the dedusting airlock is frequent along with the continuous accumulation of high-humidity dust, so that smoke dust is gradually accumulated in a conical structure (a feed hopper) at the lower end of a cyclone dust collector, and because the working temperature of the pipeline type process gas of the SDT gas cut tobacco dryer is about 160 ℃, the risk of ignition of the smoke dust exists, and the production and personal safety is seriously threatened.

At present, no good method is available in the industry to avoid material blockage, and in order to reduce the danger of fire caused by material blockage, the following two methods are commonly used: 1 patrol and examine the frequency through increasing the manual work, for example every 5 minutes go on the inspection, look over whether the dust removal airlock blanking condition is normal, in time discover behind the putty, in time clearly draw, avoid the emergence of the conflagration condition.

2 through the installation extinguishing device, whether have the spark through spark detector detection cyclone, if detect the spark and pile up the smoke and dust after the putty and have been ignited, interrupt production immediately, put out a fire. Both of the two methods are very wasteful of manpower and material resources and have very low efficiency.
