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
Current, ardealite filling in mine conveying engineering pulping process, be by ardealite in gypsum stockyard after crusher in crushing, with vibratory sieve, sieve, after screening, qualified powdery ardealite is transported to batching storehouse through conveyer belt, prepare burden in certain mass ratio with the same pulverized slag through crushing and screening, the qualified composite powder of preparing burden stirs and mixes through biaxial rneader, and then once with adhesive tape conveyor, mixed material is transported in powerful combination machine, in powerful combination machine, add water to be uniformly mixed simultaneously, the slip mixing is put into slip transfer tank, through feeding pump, send into membrane pump, last membrane pump is delivered to filling point and is filled.
There is following shortcoming in above pulping process:
1, appliance arrangement is many, and operating cost is high, and ardealite and pulverized slag all need through broken and screening, and in broken and screening process, dust is large, and operating environment is poor;
2, biaxial rneader and powerful chemical combination machine mixed effect are bad, and easily putty is stuck, cause the device can not macrocyclic continuous operation, Homes Using TV is low, and after jam, clean-up intensity is large, has increased hand labor intensity, have a strong impact on the continuous operation of device, and security is not high.
3, traditional pulping process production capacity is low, and production cost is high, and production capacity only has 25% left and right of design, reaches the more than 60% of equipment operation energy consumption at full capacity.
4, in production, need larger storehouse as transfer, in actual production process, be easily subject to the restriction in place.
5, hardening after can be bonding agglomerating, the parcel balling-up water evaporates of part phosphogypsum powder in stacking and having bad luck process.According to the characteristic mesh size of phosphogypsum powder generally all more than 15mm*15mm; therefore be less than, the harder ardealite particle of mesh size can not be sized, storage tank is not soluble delivers to membrane pump with ardealite slurry through feeding pump stirring; because harder ardealite particle jam barrier film import check (non-return) valve causes the larger Concatenate shut-down of membrane pump operational factor fluctuation, make membrane pump and long-distance transmission pipeline have major safety risks.
6, dust can stick on belt roller and make carrying roller chap again because becoming hard therefore easily hurt belt after phosphogypsum powder water evaporates, causes the hidden danger such as belt security of operation accident.
Summary of the invention
For above technical problem, the object of the present invention is to provide a kind of ardealite filling in mine conveying engineering pulping process, this pulping process can guarantee the safe operation of membrane pump and long-distance transmission pipeline in pulping process, reduce the impact on personnel, environment, the normal operation of equipment of ardealite dust and particle, it is safe, and production cost is low.
To achieve these goals, the present invention is by the following technical solutions:
An ardealite filling in mine conveying engineering pulping process, comprises the following steps:
1), ardealite and pulverized slag are put into respectively to gypsum warehouse and slag warehouse;
2), start measuring belt, by adjustings, measure belt speed, by ardealite and slag by certain compare to be listed as be delivered to premixed device, in premixed device enters blender;
3), open the water intaking valve on premixed device, the liquid-solid ratio in device to be mixed starts intense stirring device after reaching regulation ratio, makes ardealite, pulverized slag and water be mixed and made into certain density slip;
4), open wet ball mill, the pulp flow mixing is to wet ball mill, premix is not pulverized bulky grain completely and is pulverized completely in grinding machine;
5) grind the slip mixing, completely and enter in slip transfer tank from wet ball mill, open the agitating device in transfer tank simultaneously;
6), open feeding pump, slip is delivered in membrane pump from transfer tank, utilize membrane pump that slip is delivered to filling point from slurry pipeline transport pipe and fill.
Compared with prior art, the present invention has following beneficial effect:
1, production method of the present invention, its production equipment is few, and device operating cost reduces greatly, and ardealite and pulverized slag do not need through broken and screening, and are in airtight pulping system, to carry out slurrying, and without dust, operating environment is good.
2, production method of the present invention, adopt premixed device and wet ball mill to replace biaxial rneader and powerful combination machine, wet ball mill can reach 200mm more greatly to the allowed band of import ardealite grain graininess, after grinding, export granularity and can reach-100 order percent of pass 100%, thereby stopped biaxial rneader and powerful chemical combination machine mixed effect is bad, the stuck accident potential such as equipment downtime and line clogging that cause of easy putty, the method is in pulping process, the macrocyclic continuous operation of device energy, Homes Using TV is high, hand labor intensity is little, production cost is low, security and production capacity are all very high.
3, production method of the present invention does not need transfer place, can not be subject to the size of transfer site area and affect the continuity of production.
4, production method of the present invention, dust is difficult for sticking on belt roller, carrying roller is difficult for chap, can not cause because can hardening hurting belt after phosphogypsum powder water evaporates, has improved the security of belt operation, and production cost is low.
