The practice of blowing and carding line fire alarm
Most of the material in cotton spinning mill are combustible substances such as
cotton, chemical fiber etc. The frequent happening of the fire alarm in scotching
workshop is a problem that gives management personnel much trouble. Blowing and
carding procedure utilizes reciprocate bale plucker to pluck the wool. Large quantity
of wool bags stack in the workshop and large volume of combustible material is
stored in multi-box mixing openers and blowing & carding boxes. Furthermore,
through the whole procedure of the blowing and carding line, the pipes are sealed and
large quantity of blower fans and dust filtering equipments are utilized. Because of
the above situation, in case of fire alarm, large loss will happen. Not only will the
material be lost, expensive machines will also be burned and damaged. The more
important thing is that the production will be affected. In case that the blowing and
carding line stops production because of fire alarm, it will affect the production
operation of the whole spinning mill. As the blowing and carding line becomes
popular and comes to our use, the prevention of fire alarm in the blowing and carding
line becomes more important. In this text, we will discuss the prevention of the fire
alarm in the blowing and carding line and the practice process after purchasing the
product of Jiangsu Ampeon Electronic Engineering Co., Ltd.!
A. Discussion about the cause of the fire alarm
1. The iron scraps directly mix into uniaxial, biaxial and other opening
machine. So the beaters violently rub and strike with each other and that is the cause
of fire alarm.
2. The iron scraps mix into the blower with the wool flow, the high speed flying
blade of the blower fan strikes the iron scraps or iron scraps rub with turbo housing of
the fan and then spark happens and finally fire alarm happens.
3. There are ropes, stones and rags etc. remained in the wool bag. When these
sundries rub or strike with beater or fan blade, fire may also happen.
4. The problem of running such as the improper use of cotton waste. The wasted
rags is not torn down and it includes spindle, wrap cloth, so may tangle with the
beater and rub with the tangle , then fire may happen.
5. The install position of the spark diverting equipment is improper and the install
position of the spark diverting head is not within the area that fire is easy to happen.
B. Through the installing of Ampeon series metal spark diverter, we can get the
effect of ‘nip in the bud’
1. It is manifested by the practice that through the installing of AMP-119AII
spark diverter between the reciprocal bale plucker and other blower in the blowing
and carding line pipes, the fire alarm that happens when beater of the bale plucker
strikes and rubs can be prevented effectively. In the diverter of this product, the loss
of the wool wind pressure is very small. So it applies to various situations such as
positive, negative and positive & negative pressure. It is the first barrier in the safety
production in blowing and carding production line. As an integrated measure, the
installing of TF-27 bridge type iron in the blowing and carding line pipes can also
strengthen the effect of removing iron scraps.
2.Within the procedure, as multi-bin mixer and carding collect box
store large quantity of combustible material, they are the most important object of our
fire prevention. AMP-119AII spark diverter must be installed in the wool inlet. When
