Sintering and pelletizing powder receiving, storage and proportioning system

Abstract

The invention relates to a sintering and pelletizing powder receiving, storage and proportioning system, which comprises an ore storage bin, a feed inlet, a discharge outlet, a vibrator which is arranged at the discharge outlet and a quantitative tape feeding machine which is arranged below the discharge outlet. The sintering and pelletizing powder receiving, storage and proportioning system is characterized in that the ore storage bin is in a closed structure, a bag-type dust collector is arranged on one side of the top of the ore storage bin, the feed inlet is arranged in the middle of the top of the ore storage bin and is connected with a pneumatic conveying and feeding device, the pneumatic conveying and feeding device consists of a pneumatic conveying pipe unloading nozzle which is connected with the feed inlet, a metallic conveying pipe which is connected with the pneumatic conveying pipe unloading nozzle, a rubber hose which is connected with the metallic conveying pipe and a quick joint which is connected with the rubber hose, and a manual gate valve and a feeding valve which is connected with the manual gate valve are arranged at the lower part of the discharge outlet of the ore storage bin. The sintering and pelletizing powder receiving, storage and proportioning system has the advantages of simple structure, reasonable design, quick and controllable ash unloading, no environmental pollution, low maintenance rate, timely and accurate proportioning, low production cost and high economic benefit.

Description

technical field [0001] The invention belongs to the technical field of sintered pellet batching, in particular to a system for receiving, storing and batching sintered pellet powder. Background technique [0002] The composition of raw materials for sintering pellets is complex, and a certain proportion of powdery materials often need to be added to iron ore concentrates. Due to the fine particle size and small specific gravity of these powdery materials, they often appear in the process of powdery material storage and batching, polluting the environment and compounding. Inaccurate metering and other issues. At present, powdery materials are generally transported to powdery material bins by belt conveyors for storage. The bins usually use open type bins. In order to ensure the smooth feeding of materials, a vibrating device is installed at the lower mouth of the mine bin. This storage and batching method has the following problems: Since the ore bin is an open type mine bi...

AI Technical Summary

Problems solved by technology

This storage and batching method has the following problems: since the ore bin is an open type mine bin, a large amount of dust will be generated during the operation of the feeding belt conveyor and the unloading process, and the environment in the passing area of ​​the belt conveyor is harsh, and it will bring Unnecessary losses, increasing production costs
