Problems solved by technology

At present, the commonly used roller kiln for sintering battery materials is a short-distance roller kiln. This is mainly because the bottom surface of the sagger and the surface of the roller are worn to varying degrees after the sagger and the roller work for a long time, and it is easy to Deviating from the center of the furnace and colliding with the side wall of the furnace, the kiln is blocked by

Abstract

The invention discloses a full-automatic super-long roller kiln for sintering positive electrode material. The full-automatic super-long roller kiln comprises a roller way formed by roller rods and asagger arranged on the roller way, the sagger deviates from the central position of a furnace chamber after traveling a certain distance on the conventional roller rods, after the whole sagger entersa positioning device, pressure measured by a first pressure sensor and pressure measured by a second pressure sensor are added together to obtain the gravity value of the sagger, the second pressure sensor measures the pressure at a pin and transmits the pressure to a control chip, the control chip calculates the distance between the sagger and the center of a rotating shaft according to the gravity value of the sagger and moment of force between the center of the rotating shaft of the positioning device and the second pressure sensor based on the lever principle, and by comparing the calculated distance with the distance between the center of the rotating shaft of the positioning device and the centers of the roller rods, the direction in which the sagger deviates from the center of the kiln and the distance of deviation are judged. When the sagger enters a correcting device, the control chip controls the correcting device to work, and the deviated sagger is corrected. According to the scheme of the kiln, the deviated sagger can be corrected, and it is guaranteed that the sagger can be normally conveyed in the ultra-long roller kiln.

Description

technical field [0001] The invention relates to a roller hearth kiln, in particular to a full-automatic ultra-long roller hearth kiln for positive electrode material sintering. Background technique [0002] Lithium-ion battery cathode materials are the key raw materials of lithium-ion batteries. Lithium-ion battery cathode materials are generally prepared by mixing precursors and lithium sources and then sintering at high temperature in a roller kiln. The design and quality of the roller kiln directly affect the product quality of battery materials. and production efficiency. At present, the commonly used roller kiln for sintering battery materials is a short-distance roller kiln. This is mainly because the bottom surface of the sagger and the surface of the roller are worn to varying degrees after the sagger and the roller work for a long time, and it is easy to Deviating from the center of the furnace and colliding with the side wall of the furnace, the sagger blocks the ...
