Description
Technical field
The utility model relates to a kind of tailing belt lock-in control system, specifically a kind of tailing belt unit lock-in control
System.
Background technique
In ore dressing in the product of separation operation useful target components content it is lower and be not used to production part be known as tail
Mine.Tailing is the precious deposits for needing to be taped the latent power.Expert thinks that it is long-term that Mining Recycling Economy current task in China's seeks to development and utilization
The a large amount of tailings shelved.Its most common tailings transportation is exactly that multi-stage, belt is used to convey, and general control model is independent control
System --- -- i.e. each belt individually opens stopping, and since transportation range is longer, the operative employee of each belt communicates with each other inconvenience,
It is general to be carried out by the way of electric bell connection.But in practical practical process, it is found that it controls the independent of multi-stage, belt conveying
There are many defects for system: firstly, transmitting information is extremely inaccurate, only need to be judged according to the tinkle of bells number between single-stage belt, and
Mine environment is complicated, and operation on-site noise is larger, and furthermore personnel are difficult to accomplish at every moment to concentrate, and easily cause to miss
Sentence, and belt start and stop be successively open, if such as upper level belt erroneous judgement think that next stage belt has been switched on, from
And open belt, then easily cause slag stacking to be blocked on damage belt, and then delay production.Field check personnel is sent out
When existing failure, then need to think runs to inform that controllers stop belt operation in control room, and transmitting information is slower,
When belt breaks down, from information is issued, to making accurate judgment, the processing time is long, and intermediate sometimes more
Secondary confirmation, some situations often occur often causes failure to be aggravated due to finding or this is handled not in time.And for control room for
The operation of live multi-stage, belt can not learn that specific belt operation conditions, startup and shutdown depend on electric bell, and it is even more impossible to timely
Know it is where out of joint, even and if be aware of and can not also carry out direct intervention so that there is no interaction relation between each belt,
Often next stage belt goes wrong, and upper level belt, which is appointed, so to run well, and causes tailing accumulation serious, not only to failure at
Reason brings bigger difficulty, when serious, or even belt squeeze can be lived, and motor continuous service, breaks the serious consequence of belt, and
And without maintenance locking between each belt, when personnel repair, the unlatching of higher level's belt easily causes safety accident, inconvenient for use.
