Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spherical graphite shaping, in particular to a high-tapped-density graphite spheroidizing shaping system. Background Art
[0002] Spherical graphite material has good conductivity, high crystallinity, low cost, high theoretical lithium insertion capacity, low and flat charge and discharge potential, etc. It is an important part of negative electrode material for lithium-ion batteries and a replacement product for negative electrode material used in lithium-ion battery production at home and abroad. It has excellent conductivity and chemical stability, high charge and discharge capacity, long cycle life, and is green and environmentally friendly.
[0003] Spherical graphite can be obtained by crushing and spheroidizing flake graphite, usually by mechanical shaping, such as Figure 2 As shown, the raw materials enter the shaping machine through the feeder, and enter the classifier for classification under the action of the wind force of the fan. The finished products are collected at the discharge port of the classifier, and the ultrafine powder in the shaping process is collected by the dust collector.
[0004] Since the continuous feeding method is continuous, in order to maintain the normal gas-solid concentration ratio in the shaping machine, some graphite is forcibly "entrained" by the already shaped graphite into the classifier for classification as soon as it is added to the shaping machine, and becomes a pseudo-finished product to be collected, while some of the already shaped graphite is not immediately brought into the classifier for classification, resulting in "over-shaping" to become ultrafine powder. The shaping time of graphite in the shaping machine cannot be controlled. Therefore, parameters such as the tapped density and specific surface area of the graphite after shaping cannot be controlled and cannot meet the technical requirements. Utility Model Content
[0005] The utility model provides a high-tapped-density graphite spheroidizing shaping system, which aims to effectively collect ultrafine powder and finished products generated after graphite shaping, and avoid the occurrence of over-shaping or false finished products.

[0018] Beneficial effect: The setting of the support block can support the installation of the pressure gauge and provide an installation point.
[0019] Furthermore, the two pressure gauges are respectively located on the upper part of the finished product dust collector and the fine powder dust collector.
[0020] Beneficial effect: Since the inlet ends of the finished product dust collector and the fine powder dust collector are usually located below the outlet ends, and the pressure gauge in this solution is located above the finished product dust collector and the fine powder dust collector, this can avoid interference between the pressure gauge detection end and the material entering the finished product dust collector and the fine powder dust collector.
