Description

one

The invention relates to a technique for drying loose materials on a conveyor belt and can be used in various industrial zones, in particular for drying drying materials before their final drying in a rotary kiln using hot gases, leaving them from the kiln.

The purpose of the invention is to intensify the drying process by organized loosening of the material and additional heat supply due to the thermal conductivity of the rippers.

Figure 1 shows the dryer, a general view; Fig. 2 is the same, side view (divided into rotary kiln); on fig.Z - section aa in figure 2; figure 4 - section bb in fig.Z; on fig.Z - section bb In fig.Z; figure 6 is a view of G in Fig.Z.

The dryer contains a chamber 1, a ribbon nish conveyor 2, a loading device in the form of a door 3, an opening 4 for the exhaust gases, a discharge port 3, an opening 6 for entering hot gases, rippers 7 in the form of plows 8, the working surface of which is covered with a heat-conducting material 9 ,, On the rippers 7, L-shaped ribs 10 are installed. The rippers are arranged with converging 11 and diverging 12 rows and have windows 13 for crossing the material. After the discharge port 3, a transverse conveyor 14 is installed, connected via a tray 13 to a rotary kiln 16c.

The dryer works as follows.

The chamber 1 through the hatch 3 gradually loads the material, which evenly lays onto the belt conveyor 2 and, moving along chamber 1, is discharged through the window 3, the rippers 7 with the ribs 10, being in the area of the engine 123532

hot gases, heat and transfer heat to the plows 8, which are located in the layer of moving material at an angle to the longitudinal vertical plane S, turn the material over and shift it to the side; alternately in one group of rippers - to the middle of the chamber, in the other group from the middle to the edges, while the heated plows from the fins 10 transfer heat to the material in contact with it by the deposited heat-conducting material 9,

Through the opening 6 into the chamber 1 through 15, hot gases, diluted with cold air to provide a soft, dust-free drying, are given, which dry the poured material both by convective heat transfer and by the thermal conductivity of the disintegrators 7.

The material for final drying can be fed with the help of the cross conveyor 14 and the tray 13 into 2-5 rotary kiln 16.
