Blanking device used for feeding ferrite spherical particle raw materials into pre-sintering kiln

Abstract

The invention relates to a blanking device used for feeding ferrite spherical particle raw materials into a pre-sintering kiln. Devices for preventing ferrite powder from entering the pre-sintering kiln do not exist at present. The blanking device is characterized by comprising a fixing plate, a driving motor with a rotary shaft, a rotary disc, a rotary disc central isolation barrel, a rotary disc peripheral baffle, a front baffle, a rear baffle, a rotary disc peripheral baffle fixing part, a front baffle fixing part and a rear baffle fixing part. The bottom surface of the rotary disc is fixed to the end of the rotary shaft. A notch is formed between the two ends of the rotary disc peripheral baffle. A powder passage is formed between the bottom of the front baffle and the top surface of the rotary disc, and the height of the powder passage gradually increases from one end of the front baffle to the other end of the front baffle. The bottom of the rear baffle makes contact with the top surface of the rotary disc. The front baffle and the rear baffle divide the notch formed in the rotary disc peripheral baffle into a particle discharging opening and a powder discharging opening. The blanking device can prevent ferrite powder from entering the pre-sintering kiln, and prevent the phenomenon of blockage of the pre-sintering kiln.

Description

technical field [0001] The invention relates to a blanking device for feeding ferrite spherical particle raw materials into a pre-fired kiln, which is specially used for feeding ferrite spherical particle raw materials into a pre-fired kiln for pre-burning. The ferrite spherical particle raw materials can be used as Raw materials for magnetic materials such as magnetic cores, magnetic sheets, and magnetic tiles belong to the technical field of magnetic materials. Background technique [0002] The main raw materials of magnetic materials such as magnetic cores, magnetic sheets and magnetic tiles are ferrite spherical particle raw materials. The shape of ferrite spherical particle raw materials is spherical structure. When producing magnetic materials such as magnetic cores, magnetic sheets and magnetic tiles, it is necessary Use a pre-fired kiln to pre-fire ferrite spherical particle raw materials. For example, in a Chinese patent with a publication date of September 10, 2014...

AI Technical Summary

Problems solved by technology

[0003] Since the ferrite spherical particle raw material is mixed with ferrite powder, the ferrite powder enters the pre-fired kiln together with the ferrite spherical particle raw material for pre-fired, and the ferrite powder is easily burnt, resulting in a pre-fired kiln. The blockage reduces the effect of the pre-fired kiln on the ferrite spherical particle raw material, increases the workload of cleaning and maintaining the pre-fired kiln, and affects the normal production

[0004] At present, there is no reasonable structural design to separate the ferrite spherical particle raw material from the ferrite powder before the ferrite spherical particle raw material enters the pre-fired kiln, so as to prevent the ferrite powder from entering the pre-fired kiln and prevent pre-burning Device for kiln clogging
