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

Abstract

The invention relates to the technical field of iron phosphate processing, in particular to iron phosphate dehydration and crystallization equipment and an operation method thereof.The iron phosphate dehydration and crystallization equipment comprises a supporting frame and a protection box and further comprises a controller, a dehydration mechanism, a drying mechanism and a cooling mechanism, the dehydration mechanism comprises a containing barrel and a rotating assembly, and the drying mechanism comprises a receiving barrel, an extrusion assembly, a transmission assembly and a conveying assembly; the transmission assembly is arranged between the containing cylinder and the extrusion assembly, the cooling mechanism comprises an air inlet pipe and a conversion assembly, the conversion assembly is arranged on the outer wall of the supporting frame, the air inlet pipe is fixedly arranged between the conversion assembly and the receiving cylinder, and the rotating assembly and the conversion assembly are electrically connected with the controller. According to the iron phosphate dehydration and crystallization equipment and the operation method thereof, heating is more uniform, the drying and dehydration effects are improved, meanwhile, dehydrated water can be collected and converted into low-temperature gas to rapidly cool powdery iron phosphate, cooling is achieved, and then the crystallization efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of iron phosphate processing, in particular to iron phosphate dehydration and crystallization equipment and an operating method thereof. Background technique [0002] Ferric phosphate, also known as ferric phosphate or ferric orthophosphate, has a molecular formula of FePO4 and is a white, off-white monoclinic crystal powder. It is the salt of iron salt solution and sodium phosphate, and the iron in it is positive trivalent. Its main purpose is to manufacture lithium iron phosphate battery materials, catalysts and ceramics. [0003] my country's patent application number: CN201920706725.0; publication date: 2020.04.21 discloses a dehydration device for iron orthophosphate processing, including a housing and a protective housing. The top of the housing is fixed with a protective housing. The protective housing A dehydration cylinder is installed in rotation inside the dehydration cylinder, and through holes ...
