Improved portable air moving device

The invention is based on a portable air moving device for drying bricks in general. As is known in the art for making brick A drying process is provided before the bricks to firing and any finishing operations.

Such drying is generally achieved by placing the bricks in special racks within rooms are stored, in which air heated at different temperatures is introduced via suitable pipelines. In order to facilitate the drying of the bricks mentioned, the air is blown through suitable fans that move on rails steta set in motion, which are able to slide between adjacent pairs of frames. With regard to the height of the racks, on which the brick

stones have been placed, you have several, suitable beforehand Superimposed and installed fans are used to keep the bricks with the warm air in the room to dry.

Of course, the effect of the fan is exercised through a double effect, i.e. through an air suction on the one hand and by a push of air on the opposite side, decaying parallel to the axis of the fan itself, opposite the Direction of rotation of its wings.

It follows that the drying process for the through 'the flow of the fan in a certain direction Compressed air directly chipped bricks is more favored.

The air moving device demäsa of the present invention corrects the above-mentioned disadvantage, since it reverses its direction of rotation after suitable time intervals so that all Bricks to be dried, placed on two adjacent 'racks, through a direct flow of warm air be beaten alternately.

The air moving device according to the invention is also provided with a large diameter propeller, whereby the drying of all the bricks placed on all the boards of the racks themselves can be accomplished. These and other features of a functional and constructive nature of the improved movable

Air moving device and its method of manufacture, which form the subject of the present invention, can from the following detailed description and with reference to the various listed in the accompanying drawing Recognize figures better. Show it:

- Fig. 1 shows the air moving device according to the invention in one simplified perspectives forehead view;

Figure 2 is a side-rear perspective through the above Air moving device;

- Fig. 3 shows a preferred embodiment of the air moving device according to the invention, which is equipped with a Motor with a vertical axis is provided with a propeller provided with a horizontal axis via a pair Bevel gears connected; and

- Fig. 4 shows an air moving device according to the invention in Connection with a track section, at the ends of which Llicro switches are attached, which are connected to a changeover switch that controls the feed polarity of the inventive Air moving device driving Liotor reverses.

Referring now to the various numerals shown in the figures of the accompanying drawings, there is movable air moving device according to the invention from one Housing (1), which is supported by an electric motor (2) bearing stand is formed.

The said housing rests on a with wheels (4) provided V / agen, which are designed so that they can slide over guide rails (17). At least one pair of the named wheels (4) acts as drive wheels and receives the movement via the chain (5) from the motor (6), which is supported by the V / agen (3). On the mentioned V / agen 3ind the iakro limit switches on the motor (6) (14) attached, which-actuates when the carriage (3) itself arrives at the end of its slide on the rails (17) Actuation of a switch (8) and the reversal of the direction of rotation of the motor (6) itself and therefore the shift cause in the opposite sense of the carriage (3). With the shaft of the motor (2) is a suitable one Number of blades (7) provided propellers (18), which have an appropriate length so that the diameter of the Propeller itself is sufficient to create a flow of air capable of moving the bricks to be dried to knock in the frame in its full height. The shaft of the motor (2) is preferably vertical like shown in Fig. 3 arranged.

In such a specific case, the wave of the solderer lets in. Rotate gear (12) meshing with a second gear (13); the aforementioned gears (12) and (13) form a pair of bevel gears and transmit the appropriate

reduced movement of the motor (2) on the propeller, its Wing (7) around. rotate a horizontal shaft (15). Such a construction solution allows easier dismantling of the Liotors (2), if Y / maintenance work is necessary or for in the event that the latter should be changed. In a subordinate way, the motor (2) can be connected to the device be set up so that its shaft (15) is horizontal is arranged and can store the propeller (18) provided with the blades (7) as shown in FIG. 1 directly. The function of the Ko sector (2) is controlled by the timer (19) controlled, which reverses the direction of rotation of the above propeller after a reasonable period of time, wherein also the direction of the air moving device according to the invention generated air flow in this way changed we do

Said propeller (18) is also protected up to a safety height by a suitable shield, which consists of a light housing (9) is made, which stores a network (10), which is naturally provided with sufficiently wide mesh, whereby the movement of the air flow is not obstructed. The movable air moving device according to the invention, which is based on the rails (17) arranged between two racks alternate slides and, after a reasonable period of time, reverses the direction of rotation of its propeller (18), allows a faster drying process in the racks themselves.
