The drying unit system is composed of a charging machine, a discharging machine, a hot air blower, a bag type dust collector, an induced draft fan and the like. Wet materials are sent to a heating plate of a heating component in the tray dryer 1 by a feeder, the materials are stirred by a stirring component, a solvent is heated and evaporated, the materials flow through each heating plate one by one from top to bottom, and finally, a dried product is discharged by a discharging machine. The solvent evaporated from the material and the hot moisture entering from the air heater form mixed gas, and the mixed gas is discharged from the upper exhaust port of the tray dryer 1 and enters the bag type dust collector 2.

The bag type dust collector 2 consists of an upper box body, a middle box body, a lower box body, a filter bag component, a blowing component, a discharging valve and the like. The gas entering the bag type dust collector is filtered by the filter bag in the middle box body, the clean gas is discharged from the upper box body of the dust collector and is sent into the atmosphere through the induced draft fan 3. The material dust attached to the filter bag falls into the lower box body when the bag type dust collector 2 is back blown and is discharged through the discharge valve.

In the prior art, as shown in fig. 1, a disc dryer 1 and a bag filter 2 are two separate devices which are communicated through a pipeline. The equipment installation occupies large space and has high investment cost; the two devices are provided with discharging devices, and the operation and control are complex; if the dust materials discharged from the bag filter are mixed with the product materials of the tray dryer, a mixing device is additionally arranged.

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.
