Description
Technical field
The present invention relates to building material technical field, and in particular to mine tailing fluorgypsum core production technology.
Background technology
State mine is widely distributed, and tailings discharging amount is big, and the ore dressing such as iron ore, copper mine, zinc ore, key ore deposit remaining tailing amount year reaches
More than 5000000 tons.At present, the whole nation adds up up to 8,000,000,000 tons or so of the various tailings stacked, and is also rapidly increasing, seriously
Threaten the limited arable land in China.Since China's mining industry starts to walk evening, technology disparate development, the selecting and smelting technology gap of different times
Very big, a large amount of valuable resources are retained among tailing.For this reason, brainstrust appeals to accelerate exploitation and comprehensively utilizes these tailings,
It is allowed to turn waste into wealth.
Pollution of the tailings discharging to environment, the influence to ecology are always the problem of governments at all levels attach great importance to.It is for this reason, early
Just once issued in State Environmental Protection Administration in 1992《Prevent tailings pollution environmental regulations》, each institution of higher learning and scientific research
Mechanism is also carrying out the research in tailings glass direction, technology, method, constantly releases various recycling new technologies,
Carry out also having carried out substantial amounts of Tailings Dam while tailing backfill to reclaim experiment, all achieve gratifying achievement.By these years
Effort, achieve common recognition finally：Tailing is not discarded object, but utilizable secondary resource, is new era construction
Indispensable treasure.Discarded tailing is made good use of, can not only enterprise is obtained rich profit, can also effectively be changed
Kind pollution of the tailing to human ecological environment and the destruction to forest, arable land.
With the rapid development of China's industry, industrial residue is increasing and the trend that constantly spreads, it is not only occupied greatly
Farmland is measured, the serious environment that pollutes causes disaster, becomes social effects of pollution.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of quality for being able to ensure that product simultaneously
The mine tailing fluorgypsum core production technology of secondary pollution will not be caused to environment.
To achieve the above object, the technical solution adopted by the present invention is：Mine tailing fluorgypsum core production technology, it is included
Following steps：
1st, ingredient station；
Mine tailing fluorgypsum, modified starch, coagulant, glass fibre water repellent agent, after reinforcing agent is measured respectively by raw material, into
It is continuously introduced into after entering mixing screw mixing in vertical mixer.
2nd, pressing section；
Mixed serum flow to forming station from vertical mixer, is accurately injected by the actual amount of mould in mould, within a certain period of time
Pulp grinder is included by hydraulic pressure to include unnecessary material, interior conveyer belt is back in mixer and utilizes.
3rd, drying section；
Heat source is made with hot steam the molding of the gained of above-mentioned steps 2 is absorbed into heat in drying machine, cooled down rear collapsible die, use
Hydraulic press releases drying and moulding thing；
4th, repairing, the cleaning of drying and moulding thing.
After drying and moulding thing ejection die, there is the impurity left to root out in appearance drying and moulding thing, drying and moulding thing
Repaired with slurries in defective place, it is ensured that the quality of gained fluorgypsum core.
Preferably, the ingredient station described in step 1, expects the material in bag by horizontal, vertical transport equipment, conveying is simultaneously
Belt conveyer scale is sent to by rigid impeller feeding machine, unnecessary material conveys feed back bag by feed back conveyer, elevator etc. again.
Preferably, the pressing section described in step 2, in 2h including pulp grinder by hydraulic pressure includes unnecessary material.
Preferably, the molding in step 3 absorbs heat in drying machine, to reach temperature rise, molding middle reaches
From moisture evaporation but do not destroy the purpose of the crystallization water of dihydrate gypsum and mine tailing.
What the present invention produced has the beneficial effect that：Mine tailing fluorgypsum core production technology of the present invention, utilizes " three
It is useless " material such as primary industry byproduct fluorgypsum, slag powders, the fluorgypsum core of novel energy-saving environment-friendly is produced using regenerated resources
Mould, it can be ensured that the quality of product can't cause secondary pollution to environment, play the role of to environmental improvement vital.
Embodiment
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to above-mentioned technical side
Case is described in detail.
Embodiment
Mine tailing fluorgypsum core production technology, it is comprised the following steps：
