Lightweight brick production line equipment

1. Brick making process characteristics of lightweight brick production line equipment:

Lightweight brick is a kind of porous lightweight brick made of fly ash, lime, cement, etc. quality building materials.

Lightweight bricks not only have the characteristics of light weight, but also have the properties of heat preservation, heat insulation, fire prevention, and sound absorption. They are quick to build walls and have high efficacy. They can also be sawed, planed, drilled, and nailed on the spot according to temporary demand specifications. .

4. Brief description of the production process of lightweight brick production line equipment:

1. Fly ash (or lime sand) storage and treatment

(1) Fly ash (or lime sand), gypsum is a process of mixing fly ash (or lime sand) and gypsum to make pulp. During production, fly ash (or lime sand) and gypsum are added to the beating tank according to a certain ratio to make a mixed slurry. When adding water for pulping, add water quantitatively to make a slurry with a suitable concentration. Then it is pumped into the slurry storage tank by the slurry pump for standby.

(2) quicklime

Lump quicklime is transported in by dump truck and unloaded into the lime raw material storage shed for stacking. The lump lime is crushed by the compound pendulum jaw crusher and sent to the lime silo by the bucket elevator. Before grinding, the lime is fed into the closed conveyor by the feeder at the bottom of the silo and sent to the mill for grinding. The ground lime powder is sent to the bucket elevator from the discharge port of the mill, and then sent to the lime powder silo in the batching building by the bucket elevator for standby.

(3) Cement

Use bulk cement. Bulk cement is transported in by bulk cement trucks, and directly pumped into the cement powder silo of the batching building for standby.

(4) Aluminum powder

Aluminum powder in drums is purchased and stored in the aluminum powder warehouse on the bottom floor of the batching building.

When in use, it is hoisted to the second floor of the ingredient building by an electric hoist, and then manually measured and put into an aluminum powder mixer to stir into a 5% suspension for later use.

(5) Leftovers and scraps

The leftovers cut by the cutting machine fall into the bottom chute and are washed by water into the waste pool at the bottom of the cutting machine. After stirring continuously to make the waste slurry reach a certain concentration, the slurry pump in the waste pool pumps it into the waste slurry storage tank in the batching section. in spare.

2. Ingredients, mixing, pouring

Lime and cement are fed into the electronic powder metering scale by the single screw feeder at the bottom of the warehouse, and the unloading device of the metering scale is discharged to the pouring mixer after cumulative metering.

The fly ash slurry is put into the beating tank after the valve under the slurry storage tank is opened, and then pumped into the slurry electronic metering scale of the batching building for cumulative measurement. When the weight of the slurry reaches the batching requirements, the automatic control system closes the storage tank for discharging. valve, stop discharging. The measured slurry is put into the pouring mixer according to the instructions.

The aluminum powder is manually measured and poured into the aluminum powder mixer to make a suspension. The stirred suspension is directly put into the pouring mixer.

The temperature of the slurry should meet the process requirements before pouring. If the temperature is not enough, it can be heated by steam. When pouring, the mold is transported by the ferry to the pouring mixer and placed in place, and the pouring mixer discharges the material for pouring.

3. Cutting and grouping

After the static stop and initial cultivation reach the cutting strength, the cutting is carried out.

The cut body is hoisted by the semi-finished product spreader to the steam-curing trolley in front of the kettle, and two molds are stacked in each vehicle, and the stacked steam-curing trolley is pulled by a slow-moving winch on the track in front of the kettle for grouping.

4. Autoclaved and finished products

The marshaled green body is pulled into the kettle by a slow-moving winch for autoclaving curing. The constant pressure steaming time is about 8.0h, the steam pressure is 1.3MPa, and the temperature is about 190°C. After the finished product is cured by autoclaving, it is pulled out of the kettle by a slow-moving winch, and then the finished product is hoisted by the kettle lifting device to the transport vehicle, and directly discharged or stacked for storage.

5. Bottom (side) plate return, oiling of mold set

After the finished product is hoisted, the bottom plate on the steaming trolley and the trolley are hoisted to the return line of the trolley through the finished product spreader, and the trolley returns to the side of the cutting machine through the return line. The frame and the bottom plate are molded and returned. The mold is placed on the mold return track, cleaned and oiled, and then circulated for pouring.
