A kind of iron phosphate dehydration crystallization equipment and operation method thereof

Abstract

The invention relates to the technical field of iron phosphate processing, in particular to an iron phosphate dehydration and crystallization device and an operation method thereof, comprising a support frame and a protective box, as well as a controller, a dehydration mechanism, a drying mechanism and a cooling mechanism. The drum and the rotating assembly, the drying mechanism includes a receiving drum, an extrusion assembly, a transmission assembly and a conveying assembly, and the transmission assembly is arranged between the holding drum and the extrusion assembly. On the outer wall of the rack, the air inlet pipe is fixedly arranged between the conversion component and the receiving cylinder, and the rotating component and the conversion component are electrically connected with the controller. The iron phosphate dehydration and crystallization equipment and its operation method of the present invention are more uniform in heating , to improve the drying and dehydration effect, and at the same time, the removed moisture can be collected and converted into low-temperature gas to rapidly cool the powdered iron phosphate to achieve cooling, thereby indicating the crystallization efficiency.

Description

technical field [0001] The invention relates to the technical field of iron phosphate processing, in particular to an iron phosphate dehydration and crystallization device and an operation method thereof. Background technique [0002] Iron phosphate, also known as high iron phosphate, iron orthophosphate, molecular formula FePO4, is a white, gray-white monoclinic crystal powder. It is a salt of iron salt solution and sodium phosphate, in which iron is positive trivalent. Its main purpose is to manufacture lithium iron phosphate battery materials, catalysts and ceramics. [0003] Chinese Patent Application No.: CN201920706725.0; Publication Date: 2020.04.21 Disclosed is a dehydration equipment for iron orthophosphate processing, including a shell and a protective shell, the top of the shell is fixedly installed with a protective shell, the protective shell A dehydration drum is installed in the interior of the casing, and through holes are distributed on the dehydration dru...

AI Technical Summary

Problems solved by technology

[0005] 1. Only the first air guide pipe conducts hot air, which not only easily causes uneven heating, but also the amount of hot air conducted is not enough to dry the cake or it takes a long time to conduct heat to achieve thorough drying, which reduces the efficiency

[0006] 2. The water thrown out of the dehydration cylinder cannot be reused, which is easy to cause cleaning burden

[0007] 3. Multiple driving sources such as motors, electric heating wires and fans are used in the equipment, and the power consumption of the equipment is relatively large, which is not conducive to reducing costs
