The storage bin 1 is used for conveying the fly ash into the storage bin 1 for storage through a conveying mechanism or mechanical tools such as a forklift.
The fly ash is conveyed into a mixing bin 5 in a storage bin 1, ingredients are added in the mixing bin 5, and then the mixture is stirred and mixed for pelleting again, and the pelleting granules are extruded into fireproof heat-insulating materials with different densities through a mixed adhesive.
During the stirring and mixing of the fly ash, partial static electricity is generated, the adhesion of the fly ash is easily caused, and the stirring and mixing are not uniform; for this purpose, in the utility model, the bottom of the storage bin 1 is provided with a first material guiding mechanism 3, and a first conveying device 4 is connected below the first material guiding mechanism 3. The first material guiding mechanism 3 adopts two first metal brush rollers with adjustable speed and relatively rotating.

By means of fly ash, falls into the first conveyor 4 during the dosing process. The first conveyor 4 is fitted obliquely between the storage compartment 1 and the mixing compartment 5. The first conveying device 4 adopts a bolt conveyor, so that fly ash is prevented from flying and polluting working condition environments in the conveying process.
The fly ash enters the mixing bin 5 after being conveyed by the first conveying device 4, and a plurality of batching inlets 6 are circumferentially arranged on the mixing bin 5. The weighed ingredients are sequentially guided into the job mixing bin 5 through the plurality of ingredient inlets 6 in a conveying mode to be mixed with the fly ash. The fly ash subjected to static electricity removal through the first material guide mechanism 3 has strong dispersibility and can be fully mixed with ingredients.
In the embodiment of the utility model, the fly ash and the ingredients are subjected to primary scattering and mixing in a cyclone way. Specifically, referring to fig. 2, the bottom of the mixing bin 5 is rotatably connected with a rotary spreading disc 7, the rotary spreading disc 7 is connected with a gear driving device, and a plurality of discharge ports 72 are circumferentially formed in the bottom of the rotary spreading disc 7. Under the action of the driving device, the rotary spreading disc 7 rotates at high speed, and the fly ash and the ingredients are conveyed into the stirring tank 10 in a cyclone mode for multistage stirring.
The gear driving device includes: a drive motor 8; the output shaft of the driving motor 8 is connected with a driving gear 9; the rotary material spreading disc also comprises a gear ring 71 sleeved on the outer ring of the rotary material spreading disc 7; the drive gear 9 engages the connecting gear ring 71. The driving gear 9 is driven to rotate through the rotation of the driving motor 8, and the driving gear 9 is meshed with the gear ring 71 to rotate, so that the rotary spreading disc 7 rotatably connected to the bottom of the mixing bin 5 rotates at a high speed, and fly ash and ingredients are spread on the inner wall of the trapezoid mixing cavity of the stirring tank 10 in a cyclone mode.
In the multistage stirring process, a trapezoid mixing cavity which is engaged and matched with the rotary spreading disc 7 is arranged in the stirring tank 10, and a plurality of groups of mixing stirring brushes are arranged in the trapezoid mixing cavity at intervals along the height direction; the bottom of the trapezoid mixing chamber is provided with a second material guiding mechanism 13, and a second conveying device 14 is connected below the second material guiding mechanism 13. In the specific embodiment of the utility model, two groups of mixing and stirring brushes are arranged in the inner part of the shaped mixing cavity along the height direction of the shaped mixing cavity; the two groups of mixing and stirring brushes are respectively an upper layer mixing and stirring brush 11 and a lower layer mixing and stirring brush 12.
The upper layer mixing stirring brush 11 is provided with two first roller brushes which are attached to the inner wall of the trapezoid mixing cavity and rotate relatively; as shown by the arrow in fig. 1, the two first roller brushes bring the fly ash and the ingredients impacting on the inner wall of the trapezoid mixing chamber to a middle position, and the two first roller brushes are separated by a material leakage gap; so that the fly ash and the ingredients fall down in the gap to the lower mixing brush 12 to be mixed again.
The lower layer mixing brush 12 has two second roller brushes which avoid the inner wall of the trapezoidal mixing cavity and rotate opposite to each other. As shown by the arrow in fig. 1, the two second roller brushes rotate in a fitting manner. The two second roller brushes convey and mix the falling fly ash and ingredients towards the inner wall direction of the trapezoid mixing cavity, and mix and pour the mixture onto the second material guiding mechanism 13 under the action of the inclined plane of the trapezoid mixing cavity.

The second conveyor 14 is fitted obliquely between the agitator tank 10 and the granulator 15. The second conveying device 14 adopts a screw conveyer, so that the material is prevented from flying and polluting the working condition environment in the conveying process.
In the granulating process, the extrusion heat energy of the fly ash and the ingredients is increased, so that the appearance is sticky after the granulating is finished, adhesion is caused in the stacking process, and the fly ash and the ingredients cannot be fully mixed with the adhesive in the later preparation of the fireproof heat-insulating material. Therefore, inert gas is adopted to blow the particles, so that the dispersion of the particles is ensured.
Specifically, the conveying end of the second conveying device 14 faces the feeding port of the granulator 15, and the discharging end of the granulator 15 is provided with an inert gas nozzle 17; an inert gas tank 16 is connected to the inert gas nozzle, and a plurality of gas outlet holes 18 are arranged in an array on one surface of the inert gas nozzle facing the discharge end of the granulator 15 as shown in fig. 3. The particles produced by the granulator 15 are blown and dispersed by inert gas, and meanwhile, the surface layers of the particles are quickly dried, so that the formed particles do not generate adhesion in early and later application.
In the utility model, the static electricity in the fly ash is removed by adopting the metal brush in the conveying process, and the speed is adjustable, so that the conveying amount is controllable. The fly ash after static electricity removal enters the mixing bin 5 and the stirring tank 10 for proportioning and mixing, so that adhesion is prevented. The rotary material spreading disc 7 is adopted to enable the powder ash and the ingredients to realize rotational flow in the rotating process, and primary mixing is carried out; the mixing brush is rotated and mixed in different rotation directions by two groups of mixing and stirring brushes, so that the proportion is more uniform; meanwhile, inert gas is attached to the surface after granulation, so that particle separation is performed rapidly, and adhesion is prevented.
