Description
Technical field
The present invention relates to plaster calcining furnace calcining production line key equipment and supporting critical process method and technology field, specifically a kind of novel high-strength chemical gypsum powder production technique support equipment.
Background technology
Traditional gypsum calcination technology adopts vertical frying pan, rotary kiln, general fluidizing furnace etc., due to the stirring action of machinery, air-flow, terra alba is in boiling dehydration, dihydrate gypsum, semi-hydrated gypsum and dehydrated gyp-three-phase are admixed mutually, cause the phase composite of the finished product inevitably to occur heterogenize, significantly reduce product quality indicator.Terra alba can be divided into according to purposes: building materials terra alba, chemical industry terra alba, mould terra alba, food terra alba and casting terra alba etc.
The application of gypsum is long-standing, but be just used for simply in early days powder process pen, make putty, cook bean curd and do simple process product etc., lack and in depth research and develop, thus also just do not cause the attention of people.The later stage seventies in last century, since particularly China carries out reforms and opens, along with rapid development of economy, consuming the building of gypsum, building materials and the demand of other related industries to gypsum in a large number sharply increases, gypsum causes people and more and more payes attention to, and has defined huge new industry at present.
China's plaster of paris Resource management enriches total reserves and reaches nearly 60,000,000,000 tons, occupy the first in the world, also be the manufacture big country of chemical gypsum, a large amount of chemical gypsums is had to produce every year: only phosphogypsum just has nearly nearly 2,000 ten thousand tons of generations every year, the accumulating amount nearly up to ten million ton of part phosphate fertilizer plant phosphogypsum, particularly along with the develop rapidly of China's economy with in recent years to the attention of environment protection, power plant desulfurization has become the necessary process procedure in power station, create a large amount of desulfurated plasters, also has citric acid gypsum in addition, fluorgypsum, bunt gypsum and other chemical gypsum, enrich natural is relied on to carry out comprehensive utilization with manual resource, development gypsum industry is also build the needs of recycling economy, the new highlight of numerous investor especially.
Summary of the invention
The object of this invention is to provide a kind of novel high-strength chemical gypsum powder production technique support equipment, adopt efficient built-in cyclone, the dust of about 90% is laid equal stress on by collecting newly to fall back in calcining furnace, adopt the bugduster heat transfer tube that extraordinary heat-resisting steels is made, heat exchange efficiency and the high life of heat exchanging body can be guaranteed, calcination process is distinguished into four relatively independent dewatering space according to the temperature rise curve change of terra alba by locellus fluidized calcination artificially, effectively prevent the blending phenomenon of high/low temperature material, the phase composite of the finished product is optimized, this equipment is reliable, the waste gas of discharging can reach GB one class regional standard.
The technical scheme that institute of the present invention technical solution problem adopts is: a kind of novel high-strength chemical gypsum powder production technique support equipment; comprise hammer crusher 1, bugduster 2, pound hot storehouse 3, belt feeder 4 and chapelet 5; it is characterized in that: the main calcining compartment of described hammer crusher 1 adopts the heat exchange of fluidization principle; the heat transfer tube of described bugduster 2 adopts extraordinary heat-resisting steels to make; heat exchange efficiency and the high life of heat exchanging body can be guaranteed; described one-level is gathered dust and is adopted efficient built-in cyclone, the dust of about 90% is laid equal stress on by collecting and newly falls back in calcining furnace.
Described burning process adopts locellus fluidized calcination artificially calcination process to be distinguished into four relatively independent dewatering space according to the temperature rise curve change of terra alba.
Described calcining void content is answered between 45 ~ 55%, and plaster-water ratio during molding is 1:0.8:0.9.But along with the development of people's understanding, experiment and production all prove plaster-water ratio 1:< 0.8.During void content <40%, if add suitable additive in model, the midge performance of model is better than the model of plaster-water ratio 1:0.85 on the contrary, same environment, same mud forms the base substrate of same thickness, the former only needs 45 minutes, and latter needs 60 minutes model folding strengths: before time dry: rear=2:1, before time wet: rear=3:1.
Axis is had in the abrasive dust cylinder of described chapelet 5, the inwall of abrasive dust cylinder there is inside lining sleeve, axis is connected with muller by muller bar, gypsum particle raw material enters in cylinder from opening for feed and heats, middle shaft rotation drives muller and washboard to roll and rub with the hands mill gypsum particle on tower silo liner barrel, and gypsum constantly gushes to blowing up by the air-flow be blown into from blast inlet, and the thin terra alba that makes to mill moves upward, after spiral screening, gush out from discharge port.
Described plaster-water ratio is 1:0.6.
The invention has the beneficial effects as follows: 1, due to novel high-strength chemical gypsum powder production technique support equipment, adopt efficient built-in cyclone, the dust of about 90% is laid equal stress on by collecting newly to fall back in calcining furnace, adopt the bugduster heat transfer tube that extraordinary heat-resisting steels is made, heat exchange efficiency and the high life of heat exchanging body can be guaranteed, calcination process is distinguished into four relatively independent dewatering space according to the temperature rise curve change of terra alba by locellus fluidized calcination artificially, effectively prevent the blending phenomenon of high/low temperature material, the phase composite of the finished product is optimized, this equipment is reliable, the waste gas of discharging can reach GB one class regional standard,
2, because burning process adopts locellus fluidized calcination artificially calcination process to be distinguished into four relatively independent dewatering space according to the temperature rise curve change of terra alba, effectively prevent the blending phenomenon of high/low temperature material, the phase composite of the finished product is optimized;
3, because calcining void content is answered between 45 ~ 55%, plaster-water ratio during molding is 1:0.8:0.9.But along with the development of people's understanding, experiment and production all prove plaster-water ratio 1:< 0.8.During void content <40%, if add suitable additive in model, the midge performance of model is better than the model of plaster-water ratio 1:0.85 on the contrary, same environment, same mud forms the base substrate of same thickness, and the former only needs 45 minutes, and latter needs 60 minutes model folding strengths: before time dry: rear=2:1, before time wet: rear=3:1, it utilizes and is conducive to good base substrate formation;
4, owing to having axis in the abrasive dust cylinder of chapelet 5, the inwall of abrasive dust cylinder there is inside lining sleeve, axis is connected with muller by muller bar, gypsum particle raw material enters in cylinder from opening for feed and heats, middle shaft rotation drives muller and washboard to roll and rub with the hands mill gypsum particle on tower silo liner barrel, gypsum constantly gushes to blowing up by the air-flow be blown into from blast inlet, the thin terra alba that makes to mill moves upward, after spiral screening, gush out from discharge port, particle is milled into powder in the condition of high temperature, save energy, abrasive dust, calcining once completes, simplify production process, emissions reduction,
5, because described plaster-water ratio is 1:0.6, avoid that the metope of application wall ftractures, peeling, shedding and the quality problems such as to peel off, water-fast anti-ability of mixing is good, nontoxic, pollution-free.
