The technical scheme of the utility model is further improved as follows: when the disc dryer is cylindrical, the filter bag components are distributed on the circumference of the disc dryer; when the disc dryer is a cuboid with square upper and lower surfaces, the filter bag components are arranged at four corners of the disc dryer.
By adopting the technical scheme, the utility model has the following technical effects:
the utility model integrates the disc dryer and the bag type dust collector into one device, and the cylinder of the disc dryer is used as the cylinder of the original bag type dust collector, thereby greatly saving the installation occupation space and the investment cost of the device.
The utility model integrates the disc dryer and the bag type dust collector into one device, which eliminates the connecting pipelines of the two devices, reduces the resistance drop of the device system and saves energy.
The dust materials adhered to the filter bag of the utility model directly fall to the bottom of the tray dryer and are uniformly mixed with the product materials, so that the mixing device is reduced.
The volume of the cylinder body of the disc dryer is far larger than that of the original bag type dust collector, so that the air flow impact of the air inlet of the original bag type dust collector on the filter bag assembly is avoided, and the service life of the filter bag is prolonged.
The gas flow rate of the inner cross section of the disk dryer is far smaller than that of the inner cross section of the original bag type dust collector, dust materials are easy to settle when the filter bags are reversely blown, and the filtering efficiency of the filter bags is improved.
