Abstract
The utility model relates to an energy-saving type building gypsum drier, comprising a guiding spiral zone, a straight flow plate zone, a 135-degree shoveling plate zone, a 90-degree shoveling plate zone and a shoveling-plate-free zone sequentially divided from a material inlet to a material outlet; a striker plate is arranged in the middle of the drier; a circle of spinning plate is arranged in the middle of the 135-degree shoveling plate zone; adjacent shoveling plates of the 135-degree shoveling plate zone and the 90-degree shoveling plate zone are arranged in a staggered manner; part of original 90-degree shoveling plates are changed into 135-degree shoveling plates, so that the material is uniformly shoveled, and the material is dried more completely; the quantity of material in the drier is increased due to the striker plate, and the drying time of the material in the drier is increased; the number of shoveling plates of the drier in the prior art is increased, the adjacent shoveling plates are arranged in a staggered manner, the spreading of material is facilitated, and the heat exchange effect is better; and the spinning plate enables the material to be distributed more uniformly, and the heat exchange effect is better. According to gypsum powder prepared by the energy-saving type building gypsum direr, the water content is reduced, the condensation property and strength are improved, the phase compositions of the gypsum are stabilized; the productivity per hour is increased by 5 tons, and the coal consumption is reduced by 20 kg/T.
Description
Technical field
The utility model relates to a kind of dryer of producing building gypsum plaster, is applicable to the oven dry of terra alba in the Chemical Manufacture, especially take the dryer of phosphogypsum as the raw material production building gypsum plaster.
Background technology
In composite fertilizer produces, produce a large amount of residue phosphogypsums, bring the situation of great environmental protection pressure to enterprise.The oven dry terra alba is done the approach that plaster of Paris is a good solution company environmental protection pressure, and can bring economic benefit.
In chemical fertilizers production, be the One-step production line of thermal source downflow system rotary kiln oven dry calcining one because stoving process adopts the coal-fired flue-gas hotblast stove, this technique is relatively backward, has exposed following problem:
1, dries quantity is unstable
Oven dry calcining one production line at present, the production capacity of equipment is also larger, production line is short, especially the optimum temps drying time of producing semi-hydrated gypsum is short, the terra alba of producing is dihydrate gypsum, semi-hydrated gypsum, the multinomial mutual fusion of dehydrated gyp-, causes the phase composite of the finished product heterogenize unavoidably to occur.Reduced the quality index of product.The mass percent of the phosphogypsum powder of harsh product: CaSO41/2H2O 49%, anhydrous CaSO4 29%, CaSO42H2O 14%, burning, underburnt are many, when next procedure is used, the performance of condensing of product, intensity, molding time have a long way to go, and can not satisfy the plastering production line far away to the requirement of terra alba quality, and the terra alba use range is little.
2, production output is little, energy consumption is high.
Because oven dry, calcining one, the oven dry calcination time is short.Take 200,000 ton/years production lines as example, reality is phosphogypsum treatment capacity 18-20T/h(butt per hour), the 26T/h(wet basis), this production line annual capacity does not reach the design requirements of 200,000 ton/years of designed capacitys about 150,000 tons.Consume highlyer, production cost is higher, and coal consumption is controlled at more than the 85Kg/ ton.
3, production is unstable.
In the raw material gypsum bulk is arranged, easily entering belt by double-edged fine-toothed comb in feeding process calcines to dryer, the terra alba oven dry not exclusively, of poor quality, in oven dry, calcination process, be prone to " globe ", because the existence of this " globe " also easily causes the material loading of terra alba unstable, and can not accomplish in the fluidizing furnace operative employee short period of time in time to adjust calcining temperature according to the material loading amount, this has also caused the terra alba calcining inhomogeneous.
The utility model content
The problem that exists in order to overcome above-mentioned prior art provides a kind of energy-saving building gypsum dryer, but stably manufactured, and dries quantity and the output of raising plaster of Paris reduce coal consumption, economize on resources, and reduce cost.
To achieve these goals, the utility model is by the following technical solutions:
A kind of energy-saving building gypsum dryer is disposed with guide helical region, direct current plate district, 135 ° of flight districts, 90 ° of flight districts between from the material inlet to the material outlet and without the flight district; The centre of described dryer arranges blocking material plate; In the middle of described 135 ° of flight districts a circle is set and revolves flitch; The adjacent flight stagger arrangement in described 135 ° of flight districts and 90 ° of flight districts is arranged.
The beneficial effects of the utility model are: the part flight in the dryer transform 135 ° as by original 90 °, and material is evenly taken up, and is more complete through hot-air seasoning; Increase blocking material plate at the dryer middle part, increase the interior inventory (material filling coefficient is increased to 12%) of dryer and material at the drying time of dryer; The original flight quantity of dryer increases, and adjacent flight arranged by original cis and be replaced by stagger arrangement and arrange, and is more conducive to lifting, and the material-heat-exchanging better effects if; In the middle of 135 ° of flight districts a circle is set and revolves flitch, material is more evenly distributed, the material-heat-exchanging better effects if.The terra alba water content that the utility model makes reduces, and the performance of condensing, intensity improve, and have stablized the phase composition of terra alba; Output per hour improves 5 tons, Reducing Coal Consumption 20kg/T.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Wherein: 1, revolve flitch; 2, blocking material plate.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of energy-saving building gypsum dryer is divided into guide helical region, direct current plate district, 135 ° of flight districts, 90 ° of flight districts between from the material inlet to the material outlet and successively without the flight district; The centre of dryer arranges blocking material plate 2; In the middle of 135 ° of flight districts a circle is set and revolves flitch 1; The adjacent flight stagger arrangement in 135 ° of flight districts and 90 ° of flight districts is arranged.
Material enters from the dryer import, through the guide helical region in the dryer, import direct current plate district, following current enters 135 ° of flight districts, because the flight angle increases, material is easier to be kicked up, stir through overwinding flitch 1 again, make a material material less, reduce block, material is contacted with the hot blast that is blown into fully; Revolve behind the material through the stopping of the blocking material plate 2 of dryer middle part, the material take-off rate slows down, and has guaranteed the residence time of material at dryer, has further guaranteed the drying materials effect.At this moment the material that reaches 70-80% through the oven dry degree enters 90 ° of flight districts, again after the oven dry through flow into the dryer outlet without the baffle plate district, enter next process.
Although above-mentionedly by reference to the accompanying drawings embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; described those skilled in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still within protection domain of the present utility model.
