Description
Technical field
The present invention relates to the technical fields of feeder, more particularly, to a kind of feeder belt automatic adjusting device.
Background technique
Currently, feeder is widely used in thermal power plant coal furnace pulverized coal preparation system.In the process of feeder Belt Conveying
In, the phenomenon that often encountering belt deviation.Belt deviation gently then causes feeder to spread coal, belt abrasion, weigh it is inaccurate, it is heavy then
Due between belt and feeder body severe friction cause belt softening, burn or even cause fire, cause entirely produce stop
It produces.Therefore, the operation that deviation of belts of coal feeders is related to entire power plant has been properly processed.
The reason of influence factor of belt deviation has very much, causes belt deviation be it is diversified, have belt feeder itself
Internal factor, also have outside environmental elements.But integrate all is after belt relaxation itself is extended, to make belt that can not be close to two
The rotating roller of side, so as to cause received in subsequent belt rotation process vibration after shift.
Wherein, the relaxation of belt is divided into two classes, and one is belts to generate relaxation in circumferential direction causes to extend, another
Be belt occur in the width direction relaxation cause to extend, and belt no matter occur which kind of relaxation all will lead to belt deviation.
Plant personnel is by manually adjusting, mainly by adjusting tensioning rolling when encountering deviation of belts of coal feeders at present
The position of the bearing block of cylinder reaches balance to adjust the stress of belt to eliminate belt deviation.
But manual adjustment has disadvantages that.Firstly, cannot find the problem in time, many times staff is only in skin
Just it will be noted that the problem of sideslip when band has worn out serious.Secondly, work difficulty is big, especially belt is in the width direction
When relaxation extension leads to sideslip, professional person is needed just to be adjustable, otherwise the problem is easy to occur repeatedly, waste of manpower object
Power.Finally, cannot solve a problem promptly, belt deviation is only eliminated in time, just can guarantee that feeder being capable of normal continuous operation.
Summary of the invention
The object of the present invention is to provide one kind can realize automatically adjust feeder work belt make its keep tensioning to coal
Machine belt automatic adjusting device.
The technical scheme is that:
