Description

The invention relates to an air circulator which is used in drying systems in particular for. Drying ceramic molds between two Rows of items to be dried arranged so that they can be moved .st, with in IS Äen ventilators arranged one above the other which supply the drying air.

The common air circulation devices s, nd in Cangen arranged that run through the drying system and that on both sides of the goods to be dried bSrenz ". Depending on the size of the drying system are one or more air circulation devices per aisle

brought in. The job of the air circulation devices is the imported into the drying plant

the two sub-frames can be adjusted to each other according to the requirements. With smaller ones A greater depth of penetration is possible when the distance between the subframes is greater, while the subframes are pulled further apart when the items to be dried are smaller will.

According to a further feature of the invention, the wedge-shaped air baffles consist of at an angle to each other arranged guide plates, each designed to be pivotable about an axis are.

This allows the blowing direction of the material to be dried to be changed.

The fans are expediently designed to be pivotable about their vertical axis.

In connection with the pivotability of the guide surfaces of the air guide plates, the pivotability the fans are particularly advantageous if the material to be dried is only on one side of the Is located in the aisle of the air circulation device. Thus, when the guide surfaces are set accordingly, there is a flow of the air surfaces of the air baffles, the circulating air is only directed to the side where the material to be dried is located. the The whole amount of circulating air reaches the material to be dried. * 5

The invention is illustrated in more detail below with reference to the drawing. In this show in purely schematic way:

F i g. 1 is a side view of the air circulation device,

F i g. 2 is a top view of the air circulation device according to FIG

Fig- I.

Fi g. 3 is a plan view of the air circulation device, wherein

the guide surfaces of the air baffles and the fans are swiveled into a position when the Material to be dried is only on one side of the aisle of the air circulation device,

F i g. 4 shows a further top view of the air circulation device with the position of the guide surfaces of the air guide plates and the fans when inspections and maintenance are due,

Fig. 5 in plan view the arrangement of the Air circulation device in a drying system.

According to FIG. 1 and 2, the air circulation device 1 consists of a frame 2, which is divided into two sub-frames 3 and 4 is divided. The sub-frames 3 and 4 are connected to one another by coupling rods 5 and 6. the The spacing of the subframes 3 and 4 can be adjusted according to requirements by means of the coupling rods 5 and 6 can be set variably.

Each sub-frame 3 and 4 has wheels 7 on the underside, with which the air circulation device 1 on a Rail 8 can be moved. In the upper part, the subframes 3 and 4 have guide rollers 9 that are attached to run along a guide rail 10.

In each sub-frame 3 and 4 there is one or more Fans 11 and 12 are arranged pivotably about axes 13 and 14. The blowing direction of the fans 11 and 12 are directed towards each other so that the drying air from the fans 11 and 12 in Direction of arrows 15 and 16 towards air baffles 17 arranged in each subframe 3 and 4 and 18 is blown.

The air baffles 17 and 18 are wedge-shaped and thereby divide the in a stream of the fans 11 and 12 coming drying air in 2 partial flows, which are deflected laterally will. The air baffles 17 and 18 consist of guide surfaces 19 arranged at an angle to one another, 20 and 21, 22, each of which can be pivoted about axes 23 and 24.

F i g. 3 shows the air circulation device 1 in which the guide surfaces 19, 20 and 21, 22 of the air guide plates 17 and 18 and the fans 11 and 12 in such a position are pivoted that only the drying air is applied to the drying air, which is on the The discharge side of the fans 11 and 12 is located. This Position is taken when the material to be dried is only on one side of the aisle of the Air circulation device is located.

In Fig.4 it is shown which position the guide surfaces 19, 20 and 21, 22 of the air baffles 17 and 18 and the fans 11 and 12 then occupy, if Inspections or maintenance are carried out.

F i g. 5 shows the plan view of part of a drying system in which on both sides of the Driving aisle 25 of the air circulation device 1, the material to be dried 26, for. B. ceramic moldings, is arranged. The drying air is in the direction of the indicated arrows by means of fans U and 12 through the Material to be dried 26 circulated. Of course, the guide surfaces 19, 20 and 21, 22 of the air guide plates 17 and 18 can be pivoted about the axes 23 and 24 and can thus meet the drying requirements of the Items to be dried are set and adjusted. Through an adjustable opening 27 in the ceiling of the Drying system, the circulated drying air is supplied with dry air in the direction of the arrows 28. the Saturated exhaust air escapes in the direction of arrows 29 through another not shown in the drawing opening.

In addition there are 2 sheets of drawings
