Abstract
Fiber gypsum board production process and equipment are characterized in that desulphurization gypsum of a power plant or other natural gypsum is crushed and then placed into a still kettle, a proper amount of crystal modifier is added into the still kettle to realize high-temperature and high-pressure digestion, gypsum liquid slurry alpha is produced and is further directly mixed with fiber materials and light materials, mixture of the gypsum liquid slurry alpha, the fiber materials and the light materials are stirred by a stirrer to form mixed slurry capable of being poured, and the mixed slurry capable of being poured is poured and formed on a fiber gypsum production line. A fireproof fiber gypsum board produced by the aid of the process and the equipment has the advantages of light weight, high strength and low cost, and belongs to a fireproof board with an extinguishment function in the field of fireproofing. The desulphurization gypsum of the power plant is utilized, and a high additional value of comprehensive resource utilization is achieved. The gypsum alpha produced by the still kettle can be directly used for pouring without dehydration treatment, and accordingly a large amount of energy resources are saved.
Description
Technical field
The present invention relates to a kind of fibrous plaster board production technology and equipment.
Background technology
Existing fibrous plaster production is to be raw material with the alpha gypsum powder; Water mixing and other compounds then; Produce alpha gypsum powder from the desulfurated plaster of the plaster of paris or power plant and need pass through dehydration, drying, when the producd fibers plasterboard, again the water of sloughing is added again, wasted a large amount of energy.
Summary of the invention
The purpose of this invention is to provide a kind of fibrous plaster board production technology and equipment,, save a large amount of energy with chemical gypsum or plaster of paris Direct Production fibrous plaster.
Technical scheme of the present invention is: a kind of fibrous plaster board production technology; It is characterized in that: the desulfurated plaster of power plant or other plasters of paris are put into still kettle after pulverizing; Add an amount of crystal modifier and in still kettle, carry out the HTHP boiling; Produce α gypsum liquid slurry, α gypsum liquid slurry is directly mixed with fiber material and light material again, stir into pourable mixed slurry at the enterprising capable moulding by casting of fibrous plaster board assembly line through mixer.
A kind of fibrous plaster board production technology; It is characterized in that: the desulfurated plaster of power plant or other plasters of paris are put into still kettle after pulverizing; Add an amount of crystal modifier and in still kettle, carry out the HTHP boiling; Produce α gypsum liquid slurry, α gypsum liquid slurry is directly added β gypsum dry powder, fiber material, light material again, stir into pourable mixed slurry at the enterprising capable moulding by casting of fibrous plaster board assembly line through mixer.
A kind of fibrous plaster production equipment comprises in storage tank, mixer, sprue gate, the moulding belt, forming frame and cutting machine under belt, the moulding, and it is characterized in that: the inlet of mixer is connecting α gypsum still kettle and storage tank respectively.
Aforesaid fibrous plaster production equipment is characterized in that: the α gypsum still kettle of a plurality of parallel connections is arranged, the transfer storage tank of between the α of a plurality of parallel connections gypsum still kettle and mixer, connecting.The transfer storage tank can carry out production continuously.
Its advantage of fire proofing firbre plasterboard with this explained hereafter is that plate is light, and intensity is high, and cost is low, especially in fire prevention, belongs to the PLASTIC LAMINATED that fire-extinguishing function concurrently is arranged.The desulfurated plaster that has also solved the power plant is used.Make comprehensive utilization of resources reach high added value.Because directly do not pour into a mould from the α gypsum that still kettle is produced, saved a large amount of energy like this through processed.
Description of drawings
Fig. 1 is the device structure sketch map of the embodiment of the invention
Wherein: α gypsum still kettle 1, the first storage tank 2, the second storage tanks 3, mixer 4, sprue gate 5, belt 6 in the moulding, and belt 7 under the moulding, forming frame 8, cutting machine 9, drying line 10, baling press 11.
The specific embodiment
Referring to Fig. 1, embodiments of the invention 1.A kind of fibrous plaster board production technology, the desulfurated plaster of power plant (moisture about 12%) or other plasters of paris are put into α gypsum still kettle 1 after pulverizing, and press the routine techniques standard operation: α gypsum still kettle 1 adds crystal modifier natrium citricum and ammonium carbonate (adding weight ratio: desulfurated plaster 1; Citric acid 0.3%, ammonium carbonate 0.7%, water 1.5 ~ 2); In still kettle, carry out the HTHP boiling by the routine techniques standard then; Produce α gypsum liquid slurry, it is characterized in that: with the α gypsum liquid slurry in the α gypsum still kettle 1 (water content about 70%), the fiber work stone cream whisker (or organic fiber) in first storage tank 2; Send into mixer 4 with the light material (glass bead etc.) in second storage tank 3; Mixer 4 through twin shaft stirs into pourable mixed slurry, is poured into from sprue gate 5 in the moulding on the belt 6, through the combination of belt 7 under belt in the moulding 6 and the moulding; The motion of going with belt; Make the slurry after the cast reach final set through regular hour operation, by cutting machine 9 cuttings and drying line 10 oven dry, arrive baling press 11 packaging and warehousing again.
Embodiments of the invention 2.A kind of fibrous plaster board production technology, the desulfurated plaster of power plant (moisture about 12%) or other plasters of paris are put into α gypsum still kettle 1 after pulverizing, and press the routine techniques standard operation: α gypsum still kettle 1 adds crystal modifier natrium citricum and ammonium carbonate (adding weight ratio: desulfurated plaster 1; Citric acid 0.3%, ammonium carbonate 0.7%, water 1.5 ~ 2); In still kettle, carry out the HTHP boiling by the routine techniques standard then, produce α gypsum liquid slurry, it is characterized in that: with the α gypsum liquid slurry in the α gypsum still kettle 1 (water content about 70%); The β land plaster in first storage tank 2 and the compound of crystal whisker of gypsum; Send into mixer 4 with the light material (glass bead etc.) in second storage tank 3, absorb the moisture in the α gypsum liquid slurry with the β land plaster of powdered, the mixer 4 through twin shaft stirs into pourable mixed slurry; Be poured into from sprue gate 5 in the moulding on the belt 6; Through the combination of belt 7 under belt in the moulding 6 and the moulding, the motion of going with belt makes the slurry after the cast reach final set through the regular hour operation; Again by cutting machine 9 cuttings and drying line 10 oven dry, to baling press 11 packaging and warehousing.
Fiber as herein described comprises: crystal whisker of gypsum, organic fiber.
Light material as herein described comprises: perlite, glass bead or foam beads.
Because desulfurated plaster or other plasters of paris with power plant are raw material, compare as the method for raw material with the existing α of use gypsum dry powder, can save the energy greatly, cost can reduce by 70%.
