Description

Technical Field

[0001] This utility model belongs to the field of rotary kiln technology, specifically relating to a high-temperature rotary kiln device for ferric phosphate. Background Technology

[0002] The high-temperature rotary kiln for ferric phosphate is an industrial device specifically designed for producing ferric phosphate. It is primarily used in the smelting and extraction of ferric phosphate ore, as well as in the preparation of lithium iron phosphate battery materials. This equipment transforms raw materials into high-quality ferric phosphate through high-temperature heating and chemical reactions. Its core structure includes the kiln body, combustion system, transmission device, cooling system, and control system, enabling continuous material feeding, high-temperature reaction, and cooled discharge, ensuring high efficiency and stability in the production process. This equipment plays a crucial role in improving the production efficiency of ferric phosphate, reducing production costs, and ensuring product quality; it is an indispensable key piece of equipment in modern ferric phosphate production.

[0003] However, existing high-temperature rotary kiln equipment for ferric phosphate has some shortcomings in practical applications. First, the traditional heating structure design is not perfect, resulting in low heating efficiency and slow material processing speed, which affects production efficiency. In addition, the uneven temperature distribution during the heating process can easily cause local overheating or incomplete reaction of the material, affecting the consistency of the final product quality. Second, the cooling structure of the existing equipment is not ideal, and the cooling rate is slow, making it impossible to cool the high-temperature ferric phosphate to a suitable temperature in time. This not only increases the difficulty and cost of subsequent processing, but may also cause changes in the crystal structure of ferric phosphate due to the slow cooling process, thereby affecting its performance and application effect. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the installation of a heating mechanism, enables efficient heating treatment of ferric phosphate raw materials. Motor 1 drives the rotation of the screw conveyor blades, ensuring uniform material distribution within the first rotary kiln. Hot gas enters the gas collecting hood through the hot gas inlet pipe. Motor 2 controls the rotation of the bidirectional lead screw, adjusting the position of the nut block, which in turn moves the sealing block within the gas collecting hood, precisely controlling the hot gas flow rate and ensuring uniform heating of the material. This heating method not only improves heating efficiency and shortens the processing time of ferric phosphate, increasing production efficiency, but also effectively avoids localized overheating or incomplete reaction of the material, effectively ensuring the stability of product quality and making its chemical properties more stable, meeting the needs of different application scenarios.

[0013] 2. This utility model effectively solves the problem of rapid cooling of ferric phosphate after high-temperature treatment by incorporating a cooling mechanism. A water pump draws coolant from the water tank base and delivers it to the storage chamber through a drain pipe to cool the ferric phosphate in the second rotary kiln. The cooled liquid flows back to the water tank base through a return pipe, forming a circulating cooling system. Motor three drives the spiral conveyor blades two to rotate, smoothly conveying the cooled ferric phosphate. Solenoid valve two automatically adjusts the opening and closing state of the return pipe according to controller commands, controlling the coolant circulation flow rate to ensure stable and reliable cooling. This cooling mechanism can quickly cool ferric phosphate to a suitable temperature, preventing changes in its crystal structure due to high temperatures, thus affecting its performance and application. It also reduces the difficulty and cost of subsequent processing, improving the efficiency and economy of the entire production process. Attached Figure Description
