Description

Device for charging furnaces with bulk goods to be heated. Furnaces used for preheating, drying, annealing, hardening, firing etc. of bulk goods serve the same type and size, were previously loaded in such a way that the individual pieces placed next to or on top of each other on a plate or a frame or hung on it, and put the latter in the oven. This takes a lot of work and a big one Loss of time.

According to the invention, the supply of the goods is thereby more economical designed that -the final door of the furnace chamber as a container for the workpieces forms and pushes the pieces one after the other directly into the boiler room of the furnace.

In Fig. R of the drawing, an electrically heated hardening furnace is shown as an exemplary embodiment of the invention, in which the hardened material is automatically supplied in continuous operation, automatically passed on in the furnace and automatically ejected. For this purpose, the furnace space b, which is heated by resistors a, contains a traveling grate c, which runs slowly over drums d, taking the load e with it. This is stacked one on top of the other in the furnace door f formed in the storage container and is driven by the grate movement by means of a slide g, which is mounted on the table h and its drive. device -her received via a transmission gear i and a crank linkage k , pushed onto the grate c. At the end of the hike through the oven at the opposite end m, the pieces are automatically ejected. The stroke and speed of the slide can be set as required, depending on the size and type of the goods e.

The furnace door f filled with heat material e is shown separately in a perspective illustration in Fig. 2. It is closed at the bottom with a slide that is pulled out as soon as the door is placed on the carriage table h in front of the oven. If a door with load has become empty, it can quickly be replaced by a full one, which is expediently pushed in from the side perpendicular to the carriage movement by pushing the empty door to the side.

Of course, the device is also suitable for non-automatic ones and non-continuous operation as well as for each type of heating of the stove. The loading device (Slide g) can also be driven independently of the traveling grate c.

Claims (7)

PATENT CLAIMS: i. Device for loading furnace with to be heated Bulk goods, characterized in that the door of the furnace chamber is used as a container is designed for the mass pieces, from which the pieces in rows directly be pushed into the boiler room. 2. Device according to claim i, characterized in that that the rows of bulk goods by a slide, which is on one of the oven door upstream table slides to be pushed into the boiler room. 3. Device according to Claim 2, characterized in that the carriage is driven by a traveling grate from, onto which the workpieces are pushed, is moved along with it. q .. Device according to Claim 3, characterized in that the transmission ratio between the traveling grate drive and slide and thus the speed of the slide movement is variable. 5. Apparatus according to claim 2, characterized in that the slide means Crank mechanism is moved with a stroke that can be adjusted as required. 6th Device according to claim i, characterized in that the empty final door through a filled one can be replaced, which is on a slideway, laterally to the former then, is pushed in such a way that practically no air when replacing can penetrate through the door opening into the furnace chamber. 7. Device according to claim i, characterized in that the loading door is provided on its underside with a sliding lock.
