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...

Embodiment Construction

[0016] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, the sintered pellet powder receiving storage and batching system of the present invention includes an ore bin 4, a feed port, a discharge port, a vibrator 7 arranged on the discharge port and a quantitative tape feeder arranged below the discharge port. The feeder 10 is characterized in that the mine bin 4 is a closed structure, and a side bag filter 1 is provided on the top of the mine bin 4, and the bag filter 1 is used to release the gas generated by pneumatic conveying at the same time Remove the dust carried in the gas, which has little environmental pollution. The feed port of the present invention is located in the middle of the top of the mine bin 4 and is connected with the pneumatic conveying feeding device. The pneumatic conveying feeding device is composed of the feeding port Connected pneumat...
