Description

Technical Field

[0001] The present invention belongs to the technical field of rock wool production, and particularly relates to a rotary stirring device and method for recycling rock wool powder. Background Art

[0002] In the production of rock wool, after the rock wool fibers are cured and formed out of the curing furnace, a part of the redundant edges will be generated. After longitudinal cutting, edge crushing and transverse cutting, they are broken into powder. The powder needs to be recycled and stored in a tank first for convenient subsequent recycling. In addition, at the head and tail of the equipment startup, due to unstable flow, a part of the redundant plates will be generated, and during the plate picking, due to unqualified appearance, size, etc., the redundant waste plates will be selected. These plates need to be broken and then recycled and stored in the tank for secondary addition and utilization. Since the particle size of the crushed rock wool dust is small, the volume is easy to compress after collection and storage, and it is easy to agglomerate after long-term storage, which is not convenient to take out from the storage tank.

[0003] To solve the above problems and ensure the smooth extraction of the powder from the storage tank, a stirring device is usually arranged in the storage tank to disperse the extruded powder blocks and then take them out from the discharge port. On the one hand, the resistance of the stirring device in the storage tank is large, the rotation of the stirring device is relatively slow, and the stirring efficiency is low. On the other hand, the space at the discharge port is narrow, and a large amount of powder will accumulate at the discharge port, causing the discharge port to be blocked and affecting the continuity and smoothness of the discharge.
