Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing, and more specifically, to a sintering sagger for lithium battery positive electrode materials. Background Art

[0002] In the process of producing positive electrode materials for lithium batteries, it is often necessary to sinter the materials to improve their crystallinity and electrochemical properties. The sintering sagger is a container used to hold positive electrode materials and sinter them at high temperatures. Usually, a loading device is required to feed the lithium battery raw materials into the sagger, and then sinter them at high temperature in the kiln. However, when some existing loading devices are used to put the corresponding positive electrode materials, they can generally only put the positive electrode materials into the sagger from a fixed position on the top of the sagger. As a result, the positive electrode materials are easily accumulated in the middle of the sagger. As a result, with the continuous accumulation of the positive electrode materials, the top of the positive electrode materials will be against the discharge port, which will cause the materials in the sagger to affect the discharge and affect the subsequent production efficiency. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a sintering sagger for lithium battery positive electrode materials, so as to solve the problem that when the feeding device in the prior art puts the corresponding positive electrode material, the positive electrode material is easily accumulated in the middle of the sagger, causing the material in the sagger to affect the unloading.

[0010] It also includes a flattening component, the bottom of which is fixedly mounted on the top of the base plate.

[0011] Among them, the feeding assembly also includes a feeding pipe group and a connecting rod. The top end of the feeding pipe group is fixedly installed on the inner surface of the material transfer barrel, the top end of the connecting rod is fixedly installed on the outer surface of the hopper, and the bottom end of the connecting rod is fixedly installed on the outer surface of the material transfer barrel.

[0012] Wherein, the flattening assembly includes a support plate, a limiting frame plate, a second motor, and a threaded rod. The bottom end of the support plate is fixedly installed on the top of the base plate, the side of the limiting frame plate is fixedly installed on the top of the support plate, the side end of the second motor is fixedly installed on the surface of the support plate, the threaded rod is arranged inside the limiting frame plate, and the end of the threaded rod is fixedly installed on the output end of the second motor.

Under the rotation and transmission action of the first motor, the positive electrode material is transported along the end of the transfer barrel close to the connecting pipe to the end away from the connecting pipe. In addition, during the rotation and transportation of the positive electrode material, part of the positive electrode material will continuously fall into the interior of the sagger body along the feeding pipe group arranged on both sides of the transfer barrel, thereby completing the feeding operation, so that the positive electrode material falls into the interior of the sagger body more evenly, avoiding the situation where the material is easily accumulated in the middle of the sagger and causes blockage of the feeding pipe.
