Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas replacement chambers, in particular to a furnace external gas replacement chamber. Background Art
[0002] The lithium battery material sintering furnace is a lightweight continuous industrial kiln, which is widely used in the rapid sintering of ternary positive electrode materials, chemical powders, ceramic substrates and other products. It has the advantages of low energy consumption, short sintering cycle, good furnace temperature uniformity, and low labor intensity. The roller kiln is a kiln equipment for sintering lithium battery material powder materials, which can be used for sintering powder materials in an oxidizing atmosphere. The displacement chamber is a key equipment to ensure that the process gas in the furnace of the roller kiln and other kilns reaches the required concentration. It is set at both ends of the furnace. When the material enters and exits the furnace, the gas replacement is completed in the displacement chamber to ensure that the gas concentration in the furnace remains unchanged. The displacement chamber mainly includes a shell with a through channel and more than two gate sealing devices. The gate sealing device adopts a structural form in which the lifting drive drives the valve plate to lift and lower. When the valve plate rises, the inlet and outlet of the through channel are opened, and when the valve plate descends, the inlet and outlet of the through channel are closed. The valve plate must ensure that the material passes smoothly when it rises, and can ensure effective sealing when it falls.
[0003] During the material refining process, if there is air in the kiln body, it will affect the refining reaction of the material. In particular, for the kiln body that needs to be continuously fed for refining, each time the refining raw materials enter, some air will be brought in, thus affecting the reaction environment required by the material, and a large amount of water vapor will be generated each time the hot and cold air alternate, which will affect the refining results. After long-term use, garbage is easily accumulated in the gate slot, which will cause the gate to not close tightly. For this reason, we propose a furnace external gas exchange chamber.
