Description

The invention relates to the tobacco industry, namely to the production line for drying tobacco. '

The purpose of the invention is to improve the quality of dried tobacco.

FIG. 1 shows a structural diagram of a plant for drying tobacco leaves; in fig. 2 ka; measure of languor, cross-section; in FIG. 3 - a sports cart; in fig. 4 - rods 'with vertical garlands.' '

The plant contains a platform I for fixing tobacco leaves on TPM-69MB machines into a continuous cord and hanging their rods with vertical garlands, a languor chamber 2, chambers 3 and 4 of active ventilation of ventilating garlands, cameras 5 and 6 of natural drying of tobacco leaf plates, a chamber 7 for drying central vein and petiole, chamber 8 for steam-thermal processing of tobacco (fermentation), chamber 9 and 10 for humidifying tobacco garlands, sorting and packaging them in bales, located sequentially; one after another. The chambers of languor on the right and left have lower and upper windows 11 and 12 of natural ventilation, a ventilation shaft 13, a longitudinal channel 14 and transverse slots 15 located in the lower part of the chamber for the supply and distribution of air blown by the fan 16. Transport trolley used for carrying garlands , is located in the upper part of the production line, includes a frame 17, to which two driving wheels 18 with electric drives 19, two driven wheels 20, two supporting bars 21 for placing rods 22 with garlands, two mechanisms 23 for lifting and about uskaniya boards 21 over the bar 22. There are two through path 24 trough-shaped cross section in the upper part of the production line, one flange section serves as a support for the bars, and the second - to move the trolley wheels.

The operating principle of the production line is the fact that at the site of tobacco leaves 1 is fixed with the help of machines SST-69M in a continuous cord which hang garlands on a vertical rod hooks 22. The bar 22 pre uklady10887 ²

21 transport carts support the parallel bars. Support bars 21 occupy the topmost position. After the bar has been fully filled with 22 garlands, the cart is moved forward and a second bar is placed next to the first bar, on which tobacco cords from TPM-69M machines are hung with vertical garlands until the bellows bars are fully filled with vertical garlands. The thus obtained batch of garlands on the rods 22, located on the supporting bars 21 of the transport carriage, are mechanically rolled into the languishing chamber 2. Moreover, the rods are moved over the inner shelves of the tracks 24. The chamber includes

20 drive mechanism 23 lifting and lowering supporting bars and a set of rods with garlands are placed on the inner shelves of the trough-shaped paths 24. After filling the chamber

25 when the operator opens windows 1I and 12 for natural ventilation of the camera 2 of languor and, if necessary, can turn on the fan 16 without heating or with heating the air. The air through the longitudinal channel 14 is injected through the transverse slit 15 into the chamber 2 of languor, thereby ensuring full compliance with the mode of languor of tobacco leaves. After

35 extrusion of tobacco leaves at the beginning of the next day, the operator adjusts the transport trolley with supporting bars 21 located below the ends

40 rods 22, into the languor chamber 2, turns on a lifting mechanism, and the supporting bar rises, comes into contact with the free ends of the rods, raises the rods with vertical garlands. After lifting the rods, the operator turns on the transport trolley drive I9 and transports a batch of tobacco to the first active ventilation chamber 3. After stopping

50 in the required place the operator lowers the rods with vertical festoons on the inner shelves of the trough-shaped tracks 24.

After laying the first batch

55 rods transport cart returning into the chamber 2 languor, gain

the second batch of rods with festoons and

fully load the first camera

3 active ventilation. In the active ventilation chamber, open the windows of natural ventilation, turn on the fan, which forces the outside air into the chamber. In the chamber, the air rises, passes through the mass of tobacco leaves and is thrown out through the exhaust ventilation shaft.

Then the transport cart is distilled on the platform 1 loading rods with vertical festoons. As soon as the bars of the transport trolley are fully loaded, it is transferred to the languishing chamber 2, where the bars with vertical garlands are lowered.

on the inner track shelves 24. On the next day, bars with vertical garlands are transferred from the first. chambers 3 into the second chamber 4 of active ventilation of tobacco chains, and from chamber 2 languishing into chamber 3.

From the loading platform 1, tobacco garlands are transported by a transport carriage into the chamber 2 of languor. On the following day a batch of rods 22 with vertical garlands is transported from the second chamber using a transport trolley

4 active ventilation into the first natural drying chamber 5, where the plate is dried, and into the second active ventilation chamber 4 from the first chamber 3, into the first active ventilation chamber 3 from the languor chamber 2, the languishing chamber is loaded with 5-fold garlands carts. On the following day, sets of rods with vertical festoons are transferred to the following chambers and until complete drying, steam-thermal treatment and 10 moistening. From the humidification chamber 9, rods with moistened garlands are removed, tobacco cords are dispersed and leaves are transported by the conveyor to the sorting section 15 and packaging. Finished bales are sent to the storage room or for storage. The released rods are placed on top of the same transport trolley and are delivered to the platform by 20 kue, Then the transport trolley transfers the sets of rods from the steam-thermal tobacco processing chamber to the humidification chamber 9, from the center 7 stem drying machine 7 to the steam-thermal treatment chamber 8, to the chamber 7 dosushka from the second chamber 6 natural drying, and in her tobacco is transported from the first, etc. Camera 2 languor is loaded into the last 30 vertical lines.
