Abstract

The invention relates to the field of mechanical equipment, in particular to a pushing plate furnace for producing cathode material of a lithium ion battery. The pushing plate furnace comprises a special sagger and a pushing plate furnace, wherein the sagger is movably connected with the pushing plate furnace, and the pushing plate furnace comprises a feeding channel, a pushing plate furnace shell, an insulating layer, a heating system, a furnace atmosphere control system, a temperature control system, a transmission system, a discharging channel and a cooling system. The furnace atmosphere control system comprises a plurality of air inlets and a plurality of air outlets. The air inlets are arranged in the feeding channel, and the air outlets are arranged above the pushing plate furnace. The pushing plate furnace has the following beneficial effects: a position sensor is arranged in the transmission system, and cooperates with the temperature control system, so that the residence timeof the special sagger in different temperature areas in the furnace chamber is precisely controlled, and the production efficiency is improved; the cooling system with a spray head is arranged on thelower side of the discharging channel, so that the cooling speed of the finished product is improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a pusher furnace for producing positive electrode materials of lithium-ion batteries. Background technique [0002] The main constituent materials of lithium-ion batteries include electrolyte, separator materials, positive and negative electrode materials, etc. The positive electrode material occupies a large proportion, because the performance of the positive electrode material directly affects the performance of the lithium-ion battery, and its cost also directly determines the cost of the battery. [0003] The push plate furnace is a commonly used drying equipment for lithium-ion battery cathode materials. The furnace body includes a furnace shell and a furnace. The furnace shell is welded with steel plates and section steel. The bottom and surroundings are tightly welded. In addition, the push plate furnace also includes inlet and outlet pipes, furnace atmosphere control,...
