Airtight feeding device for deliquescent solid material and application method thereof

Abstract

The invention discloses an airtight feeding device for a deliquescent solid material and an application method thereof. An existing airtight feeding device has the disadvantages that a material, especially a piece-shaped or ruleless solid material, is likely to bridge or block, so that a continuous feeding process is obstructed, and the feeding speed is limited. The airtight feeding device is characterized in that a bag opening bin is arranged above a feeding bin and is connected with the feeding bin in a sealing manner through a vertical large-caliber connecting pipe, the feeding bin is of a funnel shape, and the lower end of the large-caliber connecting pipe is connected with one side of the upper part of the feeding bin; a slant baiting channel is arranged between the outer edge of the lower part of a stirrer and the slant inner wall of the feeding bin, and a discharge hole on a mouth part of the feeding bin and the lower end of the large-caliber connecting pipe are staggered. The airtight feeding device provided by the invention has the advantages that a material rapidly enters the feeding bin, and thus the batch charging time is shortened; the material is scattered through a stirring system in the feeding bin and is uniform, so that even if the material deliquesces and blocks by accident, the batch charging can be smoothly and rapidly finished.

Description

technical field [0001] The invention relates to a feeder, in particular to a device capable of rapidly and continuously feeding large quantities of deliquescent sheet-like or irregular solid materials under air-isolated conditions and its application method. Background technique [0002] The solid feeders currently on the market mainly include spiral channel feeders and rotary solid feeders, but they are not suitable for materials that are prone to deliquescent and sticky. It is easy for the outlet to be blocked and the screw to be stuck and unable to work during use. The reason for this phenomenon is that the material is very easy to absorb moisture. , Sometimes the screw is directly bonded to the channel, so that the feeder cannot work at all. [0003] Documents CN201543430U and CN2151117 are suitable for solid feeding of laboratory samples, and CN103071428A is a continuous batch solid feeding device, similar to a single-screw feeding device, but its feeding pipe and thre...

[0002] The solid feeders currently on the market mainly include spiral channel feeders and rotary solid feeders, but they are not suitable for materials that are prone to deliquescence and sticking

It is easy for the outlet to be blocked and the screw to be stuck and unable to work during use. The reason for this phenomenon is that the material is very easy to absorb moisture. , sometimes the screw is directly bonded to the channel, so that the feeder cannot work at all

[0003] Documents CN201543430U and CN2151117 are suitable for solid feeding of laboratory samples, and CN103071428A is a continuous batch solid feeding device, similar to a single-screw feeding device, but its feeding pipe and threaded connecting rod are in the same cabin, and the feeding of the discharge port The speed directly affects the amount of material in the feeding tube. When too much material is added into the feeding tube at one time, the material is easy to bridge or block, especially the flake or irregular solid material (such as sodium hydroxide, sodium sulfide, copper sulfate, etc. ), hinder the continuous feeding process, and the feeding speed is limited; secondly, the feeding pipe is directly connected to the feeding funnel, which will lead to the failure of normal feeding when the material deliquescence occurs unexpectedly

During this process, the friction between the solid material and the rotating parts is strong, not only the equipment wears seriously, but also the metal ions produced will pollute the raw materials
