Description
Technical field
The present invention relates to cement grinding field.
Background technology
In cement factory, the closed circuit milling system of the commonly used list of traditional cement grinding mill, yield poorly, power consumption high (such as: φ
4.2 × 14.5m operation power consumption 38～40kWh/d), it is impossible to meeting the requirement of country's cement industry energy conservation criteria, this is by urgent need
System implements technological transformation.Roll squeezer is applied in cement grinding system, works together with tube mill, can be greatly reduced
Grinding pow consumption, raising yield, therefore this kind of grinding system is since the eighties occurs, development is quickly.
The most conventional scheme is to use to set up roller press combination grinding, and by implementing roll squeezer technological transformation, platform produces big
Width promotes (rising 70～100%), power consumption declines substantially (declining 15～about 20%), and existing system especially O-Sepa selects powder
And dust collecting system can not meet the lifting of production capacity after technological transformation, traditional scheme is used all to change powder concentrator and gather dust and be
System, not only workload is too big, it is too high to invest, and is embodied as excessively complicated.
Summary of the invention
The technical problem to be solved is to realize one two powder concentrator parallel connections to be applied in cement grinding.
To achieve these goals, the technical solution used in the present invention is: the powder concentrator structure in parallel of cement grinding system, water
Mud grinding system includes ball mill, powder concentrator, dust collecting system, and the ball mill discharging mouth of described cement grinding system is provided with adjustable point
Glassware, described adjustable tripper is provided with two feeding-passages, and coarse powder is delivered to powder concentrator and increases newly by two described feeding-passages
Powder concentrator, the coarse powder outlet of described newly-increased powder concentrator returns powder device with coarse fodder and is connected, and described coarse fodder returns powder device by coarse powder loopback
To ball mill feeding mouth, the top of described newly-increased powder concentrator connects newly-increased dust collecting system.
The end of described ball mill connects with newly-increased powder concentrator through mill inner ventilation pipeline.
Described newly-increased dust collecting system is arranged on grinding of ball grinder tail ventilation, and described newly-increased powder concentrator is installed on newly-increased gathering dust and is
The front portion of system.
Described newly-increased powder concentrator is O-Sepa powder concentrator.
The present invention can retain and existing selects powder and dust collecting system not to adjust, and the discharging of grinding machine is entered two choosings new, old
Powder machine produces, the giving full play to of production capacity after technological transformation is fully achieved, and work on the spot amount is little, and existing system main process equipment is fully retained,
Mill room framework is also without big adjustment, and reduced investment, duration are short, have reached the Expected Results of technological transformation.
Owing to increasing a set of powder concentrator and dust collecting system on mill ventilation, go out to grind cement coarse powder sub-material and enter the old and new two
Powder concentrator, selects powder system effectively to meet the needs carrying puerperal, and two O-Sepa powder concentrator grinding efficiencies significantly improve, whole
Conjunction grinding system is stable, easy to operate, and yield is substantially improved, and power consumption declines substantially.
Accompanying drawing explanation
Labelling in the content expressed every width accompanying drawing in description of the invention below and figure is briefly described:
Fig. 1 is cement grinding parallel connection powder concentrator structural representation；
Labelling in above-mentioned figure is: 1, adjustable tripper；2, feeding-passage；3, newly-increased powder concentrator；4, coarse fodder returns powder dress
Put；5, mill inner ventilation pipeline；6, newly-increased dust collecting system.
Detailed description of the invention
Original cement grinding system includes ball mill, powder concentrator, dust collecting system, and dust collecting system includes dust-precipitator and the wind that gathers dust
Machine, for improving original system efficiency, in parallel in mill ventilation position a set of selects powder system, the systematic air flow of ball mill is greatly improved,
Meet the requirement of O-Sepa powder concentrator material-gas ratio, utilize powder material kinetic characteristic, it is achieved scalable sub-material enters two sets and selects powder
System, it is achieved the purpose of " carry product, consumption reduction, convenient to operate ".
As it is shown in figure 1, this parallel connection powder concentrator device is mainly by adjustable tripper 1, feeding-passage 2, newly-increased powder concentrator 3, thick
Expect back powder device 4, mill inner ventilation pipeline 5, powder concentrator dust collecting system six part composition.The ball mill discharging of cement grinding system
Mouth is provided with adjustable tripper 1, and adjustable tripper 1 is the cavity that an inside has cutting plate, and cutting plate is by adjustable tripper 1
Discharging opening is separated into two, and coarse powder can be divided into two-way output, adjustable tripper by two discharging openings of the most adjustable tripper 1
1 sub-material according to set proportion.By regulating adjustable tripper 1, it is achieved the distribution of two powder concentrator treating capacities, increasing is fully achieved
If the needs that after roll squeezer technological transformation, yield promotes, also ensure that two O-Sepa powder concentrators of the old and new and the balance of mill inner ventilation simultaneously
The effect produced.
Retain grinding of ball grinder tail ventilating system, set up a set of O-Sepa powder concentrator in mill tail ventilation dust-precipitator front portion, adjustable
Tripper 1 is provided with two feeding-passages 2, and coarse powder is delivered to powder concentrator and newly-increased powder concentrator 3, newly by two feeding-passages 2 respectively
The coarse powder outlet of increasing powder concentrator 3 is returned powder device 4 with coarse fodder and is connected, and coarse fodder returns powder device 4 and coarse powder is recycled to ball mill feeding mouth,
The top of newly-increased powder concentrator 3 connects newly-increased dust collecting system 6, and finished cement enters original passage.
The end of ball mill connects with newly-increased powder concentrator 3 through mill inner ventilation pipeline 5, and newly-increased powder concentrator 3 undertakes mill inner ventilation
And newly-increased production capacity select powder needs.
The present invention selects powder dust collecting system by optimization, system is carried the Material distribution in puerperal enter two powder concentrators of the old and new and
Dust collecting system, fully meets the requirement of powder concentrator material-gas ratio, reduces dust pollution simultaneously, improves grinding efficiency, improves cement work
Factory's production environment, improves the production regulation needs after System Computer changes.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by aforesaid way
Restriction, as long as have employed the method design of the present invention and the improvement of various unsubstantialities that technical scheme is carried out, or without changing
Enter and design and the technical scheme of the present invention are directly applied to other occasion, all within protection scope of the present invention.
