Problems solved by technology

[0004] Containers are stacked vertically resulting in high mechanical compressive stress in the lower container and a limited lifespan as the container deforms and occasionally breaks
The amount of powder per container and thus the throughput per unit of time is therefore limited
Furthermore, the combined effects of pressure, temperature and chemical action on the container sometimes lead to at least partial sticking at the point of contact, which becomes a major problem especially when removing containers with robots

Embodiment Construction

[0032] exist Figure 2a , Figure 2bA first exemplary embodiment of the present invention is shown in . The containers 10 shown here are all of one-piece design and have a bottom 11 and a wall 12, whereby said container 10 is designed in the shape of a bowl for containing the powder mixture. The wall 12 has a lower edge 13 and an upper edge 14 and the receptacle in the form of a hole 15 passes between said lower edge and an upper edge. The bore 15 serves to receive a spacer 16 which, in the exemplary embodiment shown, is designed in two parts and has a strut 17 consisting of a lower strut part 18 and an upper strut part 19 . The lower strut portion 18 is connected to the foot 20 and the upper strut portion 19 is connected to the head 21 . In order to detachably connect the spacer 16 to the container 10, the lower strut portion 18 is inserted into the hole 15 from below. The upper strut portion 19 is inserted into the hole 15 at the upper edge 14 until the upper strut portio...

Abstract

The invention relates to a container for storing a powder mixture during heat treatment in a furnace. The invention further relates to a furnace and to a method for heat treatment of a powder mixture. The aim of the invention is to specify a container by means of which in particular the throughput per unit of time can be increased and an automatic removal of the container is simplified. This aim is achieved, according to the invention, by a plurality of receptacles for releasable fastening of spacers which in the installed state allow contactless stacking of a plurality of containers one above the other.

Description

technical field [0001] The invention relates to a container for storing powder mixtures during heat treatment in a furnace. The invention also relates to a furnace and a method for the heat treatment of powder mixtures. Background technique [0002] In many fields of powder chemistry, in particular in the production of cathode materials for batteries, powder mixtures are thermally treated in the aforementioned container, also called a sinter. In this case, the container is made of ceramic or mullite material because these materials have good heat resistance and the container is exposed to large temperature gradients in the furnace. However, mullite containers have low chemical resistance and low mechanical strength, so these containers are sensitive, especially in chemically aggressive atmospheres and in contact with reactive materials, and are thus disadvantageous. [0003] Figure 1 shows a typical arrangement of three containers 1 known from the prior art, in each of whi...
