SU41447A1 - Endless Liner Dryer - Google Patents

Description

In the proposed dryer, intended for drying and calcining flue gases of bulk materials and relating to the type of dryers with an endless web, the latter is powered by help and a nested feeder in which the heated material coming from the bunker is heated from inside by the flue gases of the described chamber passing through the hollow axis of the feeder and then discharged by the smoke exhauster for heating the hopper.

In FIG. 1 shows a vertical longitudinal section of the dryer; FIG. 2 is a horizontal section and FIG. 3-section along /// - /// in FIG. one.

A tunnel type dryer with an outer shaft or top furnace 2, having a mixing chamber 4, is provided with an endless blade 8 rotating on a drum 13 and a nested feeder 16 installed in a receiver 17 of a material to be processed and rotating on a hollow axis 15.

Channels 14 serve to supply the exhaust gases exhausted in chamber 1 into the hollow axis 15 of the feeder. Thus, the material located in the sockets 9 pi (423)

The tatel is heated both from the outside and the inside.

With the mock 6, it is intended on the one hand to receive the calcined or dried mass coming from the dryer chamber, and on the other hand to suck air into the mixing chamber 4, using the heat of the cooling semi-finished product.

The floor axis 15 is connected by a pipe 10 to a smoke exhauster 18, which directs the flue gases to the casing 20 of the hopper 21 and to the pipe passing through the last discharge pipe 22.

The raw material is lifted by the lift 24, by gravity 23 is sent to the bunker 21, where the initial heating of the raw material takes place; in crushed form by gravity 19, the raw material enters the receiver 17 of the semi-finished product.

From the receiver, the raw materials are fed by a nested feeder 16, having special feeding nests 9, while simultaneously dosing and dewatering the material onto a moving endless web 8, from which it is poured into the container 6.

The installation is driven by one motor through a system of gears mounted on shafts 11.

The dryer is primarily intended for drying and calcining mineral granular materials.

The subject matter of the invention.

Endless blade dryer for drying and calcining flue gases

bulk materials, characterized by

using a drum feeder 13 with sockets rotating on a hollow axis 15, which is connected to channels 14 with a drying chamber for transmission, for the purpose of heating the feed material, through a flue gas feeder discharged through pipe 10 with an exhauster 18 for directing it to a hopper 21.
