Description

In the usual method of drying brick masonry in tunnel drying ovens, the raw material is placed on a drying car, a net, equipped with racks with shelves for its laying. The dried raw from the drying cars is shifted to the kiln cars of 012-14 rows for directing to the kiln.

In the proposed method of drying the raw material, the latter is immediately loaded onto the kiln car, placed in several rows, and as the raw material is dried, it is sequentially loaded onto the same car, which is performed two, three or more times when the car goes from one drying channel in another; upon filling the same trolley, the latter is sent to a tunnel kiln for burning.

In FIG. 1 shows a diagram of a tunnel drying oven intermittently designed for the proposed method of drying the raw material for loading the raw material; and FIG. 2 through 4 are transverse sections of successive drying channels with trolleys with dried raw in them.

For the implementation of the proposed method of drying the raw material, a tunnel drying Nech was used, consisting of several separate channels 2, 4, 6, 8 (Fig. 1), in front of which and in between. between which are installed

presses 3, 5, 7 for making raw. In cross section, channel 2 (Fig. 2) is lower than channel 4 (Fig. 3), which, in turn, is lower than channel b (Fig. 4), etc. Raw material to be dried, obtained from press /, load t immediately on the sintering in a network, laying on it from two to four rows (Fig. 2); when the cart passed through the canal and the raw material was dried on it so that it allows the laying of subsequent rows, another two to four rows of raw material obtained from press 3 are laid on the lower rows of raw materials (Fig. 3). In the same way, after the passage of the subsequent channel 4, several more rows of raw material are added, etc. From the last drying channel, the trolley with dried raw material is fed to the kiln for firing.

The subject matter of the invention.

The method of drying raw clay products in canal driers with intervals for additional loading of the material being dried, characterized in that the raw load on the truck in rows of raw wet cages is sequentially reloaded on the same truck after drying when switching from one drying channel to another, which is done two , three or more times, and after filling the car, it is sent to a tunnel kiln for final calcination, i
