Bei dem erfindungsgemäßen Trockner findet also eine direkte Beheizung der umgewälzten Luft statt.In the case of the dryer according to the invention, there is therefore direct heating of the circulated air.

Die Lüfter 3 a, 3 b saugen bei der dargestellten Ausführungsfonn die Luft aus der Kammer 1 ab und bewegen sie durch die Kammer2 hindurch. Die Luft wird dann an der Übergangsstelle von der Kammer 2 zu de;: Kammer 1 durch die aus den Löchern 5 a des Brennrohres austretenden Verbrennuagsgase erwärmt und in die Kammer 1 angesaugt. Ein Teil der Umluft geht dabei als Abluft über den Kanal? ins Freie. Es versteht sich von selbst, daß diese Abluft durch Frischluft ersetzt werden muß. Eine Öffnung 8 ist dafür vorgesehen. Die Bewegungsrichtung der Umluft kann dadurch umgekehrt werden, daß der Lüfterwagen 3 in eine Stellung verfahren wird, in welcher er mit der Kammer 1 fluchtet.In the embodiment shown, the fans 3 a, 3 b suck the air out of the chamber 1 and move it through the chamber 2. The air is then heated to the point of transition from the chamber 2 to chamber 1 through the de ;: from the holes 5 a of the fuel pipe exiting Verbrennuagsgase and sucked into the chamber. 1 Some of the circulating air goes through the duct as exhaust air? into the open. It goes without saying that this exhaust air must be replaced by fresh air. An opening 8 is provided for this. The direction of movement of the circulating air can be reversed in that the fan carriage 3 is moved into a position in which it is aligned with the chamber 1.

Der thermische Wirkungsgrad des erfindungsgemäßen Trockners ist außerordentlich günstig. Auch ist der Leistungsbedarf der Lüfter 3 a, 3 b des Lüfterwagens sehr klein.The thermal efficiency of the dryer according to the invention is extremely favorable. The power requirement of the fans 3 a, 3 b of the fan carriage is also very small.

Claims

The object of the invention is to meet the thermal claims: to increase the efficiency of this known dryer

1. Dryer for ceramic products, this task is thereby changed according to the invention two adjacent chambers 5 releases that the heater at the transition point is arranged alternately with circulated, in horizontal from one to the other chamber. Direction of flowing air one after the other due to the special arrangement of the heating elements This air is fed to a heater at the transition point from the one hammer device is passed, and also one in the other chamber is ensured that on The air speed traverses a maximum at this point transversely to the longitudinal direction of the dryer rer fan car is provided through which reached, since the entire amount of air through this the direction of flow of the drying air must pass through the "sluice". The very high ones is reversible, characterized in that fuel gas temperatures are at this point at that the heating device at the transition point emerges from the burner with the one flowing past from one to the other chamber (1 or 2) 15 circulating air intensively mixed before the arranged is. heated circulating air to the temperature-sensitive

2. Dryer according to claim 1, characterized in parts of the fan located in the fan carriage, that the heating device reaches out of one becomes a great part of the goods taken up Burner (6) receiving combustion tube (5) memenge released to the charge so that ώε with recesses distributed around the circumference, ao bearings, motors and cable feeds for the Luiter gen exists. the high temperatures of the combustion air

3. Dryer according to claim 2, thereby being pulled.

indicates that the recesses have the shape In a further embodiment of the invention

of two rows of holes, one of which has the heating device from one a burner on each from the superimposed holes (5 a), the burner tube is distributed around the circumference, orderly recesses. _

"Appropriately, the recesses have the rorm of two rows of holes, each of which consists of holes one on top of the other.

30 Claims 2 and 3 are not independent

Meaning, they only apply in connection with claim 1.

The dryer of the present invention is below

Patent specification 36 278 of the Office for Invention Chambers 1,2, which can be optionally and patenting in East Berlin shows a 45 rolled air can be acted upon. The overturned Dryer with two adjacent chambers air flows through these two chambers 1.2 in mern, which are horizontal from one another through a central wall. The air is at the are separated. On both sides of the chambers, transition from chamber 2 to chamber 1 is shown A fan carriage is provided for each end face, which heats up.

which several fans are arranged. 50 The reference number 3 designates a fan trolley. These fan trolleys are moved offset on rails, which in the direction of arrow A in FIG. 2 verbar and are controlled in such a way that it is mobile after a short time. The fan trolley 3 has in the Darge time intervals simultaneously change location presented embodiment two superimposed and thus reverse the air direction, with the fans 3 a, 3 b.

Circulating air in the horizontal direction through the chamber 55 Between the two chambers 1, 2 a core is moved through. Arranged on the partition 4 away from the doors. In the throughput cross-section B facing sides of the dryer are in the chambers of the transition point from chamber 2 to the channel - in the blowing direction of the fans of the fan heater, a combustion tube 5 is arranged, which, viewed in turn, is a finned tube heating element that accommodates burner 6. This can be one that is used to heat the circulating air. 60 oil burner or a gas burner.

The disadvantage is the comparatively low thermal efficiency of this known dryer, which is distributed around the circumference. The orderly recesses through which the hot reason for this lies is that the speed combustion gases escape through. In the case of the air quantities passing through the heating register, F i g. 1 have the embodiment shown, which is equally small. According to the laws of the ther- 65 recesses in the form of two rows of holes of modynamik this means but relatively little heat which each consists α superposed holes transfer coefficients and thus also small heat emissions. 5 However, the invention is special to this. Their embodiment is by no means restricted.
