Abstract

The invention relates to a drying technique. The purpose of the invention is to reduce fuel consumption. For this, the exit tunnel has a flow cooling zone. The zone is provided with an autonomous recirculation system. Cold air is supplied to the deposited zone B, which, while cooling the product, is heated. This air is then supplied to the mixing shaft and then to the drying zone B. Part of the air is taken from the dryer and fed to the shrink zone A. The remaining part of the exhaust air is emitted into the atmosphere. 2 Il. with 4 :: CA: Yu Figure 2

Description

 P

The invention relates to a drying technique, namely, devices for drying ceramic products.

The aim of the invention is to reduce fuel consumption.

On (| ig. 1 shows the proposed device, a longitudinal section; in Fig. 2 - the same, with the recirculation systems, LLAIL, plan.

The device contains zones of shrinkage A, dosushka B, cooling B and is equipped with nozzles of exhaust heat carrier 1 and recirculated air 2, recirculation air supply 3 and 4 and cold air 5 and exhaust of heated air 6, exhaust heat carrier 7 and exhaust pipes 8 and supply 9 recirculated, supply fresh coolant 10 and. cold air 11 and exhaust heated air 12, exhaust fans coolant 13, recirculate 14, supply fresh coolant

15 and cold air 16, and also contains a mixing shaft 17.

The device works as follows.

To the cooling zone in the fan

16 through pipe 5 serves cold air, which cools the product and

heats up himself. Then this air is taken through the pipes 6 and through the discharge pipeline 12 is fed into the mixing shaft 17 and then with the help of the fan 15 through the pipeline 10 is fed into the drying area B through the patCt

Cabins 4. A part of the exhaust air through pipes 2 is taken from the dryer by the fan 14 and fed through pipe 9 to the shrinkage zone A through pipes 3. The remaining part of the exhaust air is emitted through the pipes 1 by the fan 13 into the atmosphere.
