"Drying chamber, especially for drying sawn timber"

The invention relates to a drying chamber, in particular for

Drying of sawn timber, with at least one fan for circulating the T _r ockenmittels, in particular air.

Purely the drying of sawn timber and other goods is of The advantage of reversing the air flow from time to time in order to achieve even drying at all points in the drying chamber. For this purpose, a permanently installed fan that is reversible in its direction of rotation is used Direction of rotation of the desiccant in one conveying direction and in its to promote other direction of rotation in the opposite direction, only has a low level of efficiency.

The invention makes it possible to use a fan with a high degree of efficiency, which promotes only one sighting, which is achieved in that the fan can be pivoted about an axis, in particular at right angles, to its axis of rotation and in a specific axis Determine the swivel position ie f.- To reverse the conveying direction , the fan is swiveled by 180 ° and can thus maintain its direction of rotation *

This allows simply designed fans with a high Use efficiency.

In a further development of the invention, a ring surrounding the fan wheel has two dnander iir. essentially diametrically opposed Set up bearing journals for mounting the fan, with at least a drive wheel is attached to one of the journals. The pivot bearing for the fan can be designed in a simple manner. With help of a Drive wheel, the fan is to be pivoted around its pivot axis, or to be set in its operating position, for which purpose the drive wheel is at least is indirectly connected to a servomotor. ,.,., ..

A particularly advantageous embodiment of the invention is to put t he swivel axis of the fan is eccentric to its axis of rotation and to provide a hwenklage _c at will from its stop position to be brought to secure the stop S of the fan. As a result, pivoting forces generated by the fan itself are used and, instead of a pivoting member, only a stop that can be actuated at will needs to be provided.

In the drawing is a drying chamber as an embodiment of the Subject of the invention shown schematically. Show it .Pig. 1 shows a cross section through the drying chamber. FIG. 2 shows a detail from FIG. 1 on a larger scale 3 shows a section along line III-III in FIG. 2; FIG. 4 shows a modification of the embodiment according to FIG. 3.

A drying chamber 1 has a cover 2, which has on its sides the flow openings 3 and 4, of which the flow opening 3 by a izregister H _e is 5 covers. Between the ceiling 2 and the roof of the drying chamber 1, a fan 6 is mounted such that it can pivot about an axis perpendicular to its axis of rotation. A _u f to the bottom of the drying chamber 1 are provided four rows of longitudinally of the drying chamber with the aid of Fphrzeugen movable timber stack; To the

Drying of the sawn timber, the fan 6 conveys heated air through the heating register 5 in the direction of the arrows drawn through the sawn timber stacks 7 and the flow openings 3 and A. If the fan 6 is swayed by 180 °, the conveying direction is opposite to the direction of the arrow "- -

The fan 6 has a fan ring 8 on which a drive motor 9 is attached, on the tic-ssen axis of rotation a fan wheel 1Ö sits on the fly, that is roughly in the transverse center; of the fan ring 8 is '' this one The ring has bearing journals 11 and 12 on two diametrically opposite sides, which in one of them correspond to the fan ring Recess having intermediate wall 13 are rotatably mounted. Of the Bearing pin 11 has a drive wheel 14 on its foot, which has a Drive pinion 15 käcct. Pieses pinion is on a shaft the intermediate wall 13 attached servomotor 16 attached. Of the Drive motor 9 is by means of struts 1? firmly connected to the fan ring 8.

If several fans are planned, each fan can have one Be provided servomotor. However, it is more beneficial if it is present several. "Fan. The swiveling movements on the individual fans with the help of a drive chain to transmit "the τοη a servomotor is driven. A hydraulic or pneumatic working cylinder can also serve as the setting motor. The fan can also be from Hand pivoted and set in seller's respective pivot position.

The embodiment of Fig. 4 differs _u sführungsbeispiel in substantially the arrangement of the bearing pin 11 of the above A ', and 12 ", whose joint axis is arranged eccentrically to the axis of rotation of the fan 10. The here with 8' designated fan shroud must in this case symmetrically to the axis of the pivot .. pin 11 'and 12! and the partition wall 13 "are designed accordingly, so that the fan and the ring surrounding it in" one "two pivoted positions offset by 180 ° from one another" in the intermediate

wall 13 'provided free space with the exception of the game necessary ^{to pivot des'Lüfterringes 8 1 covers.} For the purpose of making the fan ring 8 'symmetrical to the axis of the bearing journals H' and 12 ', a sickle-shaped shoulder 18 is provided on the fan ring 8'. ·. ·

The pivot position of the fan ring 8 'is to be secured by an anchor of a magnet formed 19 A _n achlagglied 20 which in the rest position 8 a stop for the, fan ring' forms and in its attracted position pivoting of the fan ring 8 'about the bearing journals 11 * and 12 ^f allows the fan to perform as a result of the eccentric reaction forces acting on it. The fan ring 8 'is located in the adaption of new ^Sw en-suit again against the stop member 20th

The fan of a drying chamber generally changes its pivot position only at large time intervals, e.g. B. after hours.
