Description
Technical field
The present invention relates to a kind of ardealite filling in mine conveying engineering pulping process, belong to filling in mine conveying engineering applied technical field。
Background technology
Currently, ardealite filling in mine conveying engineering pulping process, be by ardealite in Gypsum Fibrosum stockyard after crusher in crushing, sieve by vibrosieve, powdery ardealite qualified after screening is through conveyer belt transport to dispensing storehouse, dispensing is carried out in certain mass ratio with the pulverized slag also passing through crushing and screening, the composite powder that dispensing is qualified stirs mix homogeneously through biaxial rneader, then with adhesive tape conveyor, mixed material is transported to powerful combination machine again, in powerful combination machine, add water to be uniformly mixed simultaneously, the slip of mix homogeneously puts into slip transfer tank, membrane pump is sent into through feeding pump, last membrane pump is delivered to filling point and is filled with。
Above pulping process has the disadvantage in that
1, appliance arrangement is many, and operating cost is high, and ardealite and pulverized slag are required for through broken and screening, is crushing and in screening process, and dust is big, and working environment is poor；
2, biaxial rneader and powerful chemical combination machine mixed effect are bad, it is easy to putty is stuck, cause the device can not macrocyclic continuous operation, Homes Using TV is low, and after jam, clean-up intensity is big, adds hand labor intensity, have a strong impact on the continuous operation of device, and safety is not high。
3, tradition pulping process production capacity is low, and production cost is high, about the 25% of production capacity only design, reaches more than the 60% of equipment operation energy consumption at full capacity。
4, need bigger storehouse as transfer in producing, actual production process is easily subject to the restriction in place。
5, stack and have bad luck in process part phosphogypsum powder can bonding agglomerating, wrap up balling-up water evaporates after hardening。Characteristic mesh size according to phosphogypsum powder is general all at more than 15mm*15mm; therefore will not be sized less than the harder ardealite granule of mesh size, not readily dissolve at stirring storage tank and deliver to membrane pump with ardealite slurry through feeding pump; because harder ardealite granule jam septum inlet check (non-return) valve causes the membrane pump operational factor bigger Concatenate shut-down of fluctuation, membrane pump and long-distance transmission pipeline is made to there are major safety risks。
6, dust can stick to and make on belt roller that carrying roller is thicker easily hurts belt because becoming harder after phosphogypsum powder water evaporates again, causes belt to run the hidden danger such as security incident。
Summary of the invention
For above technical problem, it is an object of the invention to provide a kind of ardealite filling in mine conveying engineering pulping process, this pulping process can guarantee that the safe operation of membrane pump and long-distance transmission pipeline in pulping process, reduce the impact that ardealite dust and granule are properly functioning on personnel, environment, equipment, its safety is high, and production cost is low。
To achieve these goals, the present invention is by the following technical solutions:
A kind of ardealite filling in mine conveying engineering pulping process, comprises the following steps:
1), ardealite and pulverized slag are respectively put in Gypsum Fibrosum warehouse and slag warehouse；
2), start measuring belt, by regulating measuring belt rotating speed, ardealite and slag are delivered to premixed device by a certain percentage, enter in blender through premixed device；
3), the water intaking valve opened on premixed device, the liquid-solid ratio in device to be mixed reaches to start after regulation ratio intense stirring device, makes ardealite, pulverized slag and water be mixed and made into certain density slip；
4), opening wet ball mill, the slip of mix homogeneously flow in wet ball mill, and premix is not pulverized bulky grain completely and pulverized completely in grinding machine；
5) slip grinding mix homogeneously, completely enters in slip transfer tank from wet ball mill, opens the agitating device in transfer tank simultaneously；
6), open feeding pump, slip is delivered in membrane pump from transfer tank, utilizes membrane pump that from slurry pipeline transport pipe, slip is delivered to filling point and be filled with。
Compared with prior art, the method have the advantages that
1, production method of the present invention, it produces, and equipment is few, and plant running expense is substantially reduced, and ardealite and pulverized slag need not move through broken and screening, and are carry out slurrying in airtight pulping system, and without dust, working environment is good。
2, production method of the present invention, premixed device and wet ball mill is adopted to instead of biaxial rneader and powerful combination machine, the allowed band of import ardealite grain graininess can be reached more greatly 200mm by wet ball mill, after grinding, outlet grain size can reach-100 order percent of pass 100%, thus having stopped biaxial rneader and powerful chemical combination machine mixed effect is bad, easy putty is stuck causes the accident potential such as equipment downtime and line clogging, the method is in pulping process, the device macrocyclic continuous operation of energy, Homes Using TV is high, hand labor intensity is little, production cost is low, safety and production capacity are all significantly high。
3, production method of the present invention does not need transfer place, will not be affected the seriality of production by the size of transit depot ground area。
4, production method of the present invention, dust not easily sticks on belt roller, carrying roller is not easily thicker, does not result in because of the hardening incised wound belt of meeting after phosphogypsum powder water evaporates, improves the safety that belt runs, and production cost is low。
