The invention refers to a material transfer technology, so as to overcome the problem that interlocking control on material blockage prevention is not carried out in a transfer process of powder / particles materials in the prior art. The technical scheme can be concluded into: according to the interlocking control system for material accumulation in a bucket elevator, a valve is arranged on a windsupply pipeline which is able to supply a wind supply channel for a pneumatic conveying device; the bucket elevator is provided with corresponding state detection modules, and the control module can control opening or closing of the valve according to the states of the bucket elevator. The invention has the beneficial effects that the wind source can be cut off when failure occurs, so the materialtransfer can be stopped to prevent a large number of materials from being accumulated at the bottom of the bucket elevator, and then a false escalation and an equipment trouble caused by the materialaccumulation can be avoided; and meanwhile, as the material transfer is stopped in time, so the number of materials accumulated at the bottom of the bucket elevator is relatively less, which is convenient for staff to do follow-up cleaning and maintenance. The invention is especially suitable for a transfer system for aluminium oxide.
Description
technical field [0001] The invention relates to material conveying technology, in particular to powdery and / or granular material conveying technology. Background technique [0002] At present, dense phase conveying, super dense phase conveying and other pneumatic conveying methods are mostly used for conveying powdery and / or granular materials, and bucket elevators are used to lift materials, such as the conveying of alumina in the process of electrolytic aluminum. During the transportation process, due to the failure of the bucket elevator and the blockage of the post-stage discharge facilities such as the transfer warehouse, the material will accumulate at the bottom of the bucket elevator, and then the material will flood the bucket elevator runner and hopper. In view of the above problems, although there is a fault alarm device in the prior art, there is no corresponding interlock control system, so that the processing of the fault is not timely, so when a fault or block...
