Accompanying drawing explanation
Fig. 1 is the schema of flyash ultra-fine fibre production method in a preferred embodiment of the present invention;
Fig. 2 is the structural representation of flyash ultra-fine fibre production equipment in Fig. 1 embodiment.
Embodiment
Below in conjunction with accompanying drawing and a preferred embodiment, technical scheme of the present invention is further described.
Consult Fig. 1-2, this coal ash ultra-fine fibre production equipment comprises electric furnace 1, whizzer 2, cotton collecting machine 3 and tablets press 4.
The production equipment that the present embodiment adopts comprises following integral part:
Found system: the system of founding adopts clean energy, that is, electric energy carries out inside heating to flyash at electric furnace 1, and it is introduced electric current in flyash solution by electrode, solution by electrode produces joule heating under the effect of alternating-current, thereby reaches the object of fusing and temperature adjustment.Electric furnace 1 power transmission is three electrode pair electric furnace 1 three phase supplies (power supply parameter is low voltage, large electric current) by being inserted above by electric furnace 1.Electrode is contained on electrode holde, adjusts the upper-lower position of electrode, to guarantee the temperature of melt with electrode holde.The interior melt of electric furnace 1 is flowed out by the electric furnace 1 special head piece in side.The iron restoring in melting process is emitted by putting iron machine in electric furnace 1 bottom side.
Fiberizing system: melt-flow falls into the whizzer 2 of being furnished with vane through movable chute, draftedly under the action of high-speed airflow providing with vane in high speed centrifugation power become fiber, also can spray into binding agent and dust laying oil by sprinkling system simultaneously, fiber is blown in cotton collecting machine 3, the separated pit that falls into of slag ball, is regularly transported by load wagon cleaning.
Collect cotton system: by the cotton mode of triangle guipure collection fiber that fiberizing system is sent into, that sprayed binding agent, collect.The fiber that contains binding agent, under the blowing of whizzer 2 and vane and the acting in conjunction of cotton collecting machine 3 suction wind, forms just cotton felt on the collection web plate surface of high-speed cruising.The square meter that collects the first cotton felt of speed adjustment of cotton drum by change weighs to reach the requirement of product, and meanwhile, the slag ball of generation passes through slag ball roller by effectively separated.
Granulating system: the first cotton felt that triangle guipure is collected is through tablets press 4, and cutting into diameter is the fiber cotton-wool of 4.5-5.5cm, and further that slag ball is separated with fiber cotton balls by roller screen.
Wherein, whizzer 2 adopts four roller whizzers, and it is around around the vane being communicated with high-pressure blowing-in equipment is set; Whizzer 2 can be designed to dolly form, and can walk in orbit, each roller of whizzer is fixed on tubular shaft, the latter is supported by the bearing of mist lubrication, each is by a motor-driven, each running roller is with chilled water unit, and high-temperature fusant, under the effect of four roller centrifugal force, is got rid of and makes fiber.Cotton collecting machine 3 adopts the cotton mode of triangle guipure collection, and it is mainly comprised of cotton collecting chamber, the triangulation network, wind chamber, quill shaft, chain drive system, the cotton device of liter, sealed roller, slag ball tripping device (comprising front curtain, slag ball roller, slag ball stopper plate, slag ball pivot cutter), collection web plate purging system (comprising three groups of brush rolls, water blast gun, high pressure air rifle, chute, blowing dryer), platform etc.
The production method that the present embodiment adopts is as follows: adopt and take flyash as main raw material, rhombspar, slag are the raw material that auxiliary material forms, and adopts electric furnace 1 fusing.Acceptable material, by after proportioning automatic weighing, is dropped in electric furnace 1 and is carried out electrically heated by conveyor, melt raw material, and electric furnace 1 Nei Wenduda is more than 1800 ℃, and melt is flowed out by electric furnace 1 stream material mouthful, through movable chute, is imported into whizzer 2 fibroblasts.Whizzer 2 forms by the Centrifugal rolling running up with around the vane outside Centrifugal rolling.The high-temperature fusant drawing-off under the centrifugal force of Centrifugal rolling and the compound action of the high velocity air being sprayed by vane that flows into whizzer 2 becomes fiber, and fiber is blowed to cotton collecting machine 3, in fiberizing process, the velocity contrast that utilizes itself and slag ball is separated the slag ball of fibroblast not effectively, very convenient, meanwhile, adopt air atomizing and multi-point injection mode, binding agent is applied to fiber surface equably.
Fiber is evenly adsorbed to the collection cotton of high-speed cruising and is with under the negative pressure wind suction function of cotton collecting machine 3, forms very thin first cotton felt, and first cotton felt is sent into tablets press 4.Tablets press 4 cuts into first cotton felt the fiber cotton-wool of diameter 4.5-5.5cm, and fiber cotton-wool rotates by roller screen, further that slag ball is separated with fiber cotton-wool.Remove the fiber cotton-wool of slag and just can pack warehouse-in.
Wherein, raw material packet is containing the slag of the flyash of 60wt%, the rhombspar of 20wt% and 20wt%, and its composition is roughly as follows: SiO
243.94wt%, Al
2o
