QWT21 Automatic Concrete Block Production Line

QWT21 automatic concrete block production line applies the SHI FENG automatic block making machine which is designed based on the domestic and overseas markets. The machine adopts the national advanced control system. Its performances and technological level is the same as that of the overseas counterparts. Our machine adopts the modular design. Also, we can customize the machine based on the clients’ requirements.

1. Production Line Equipment
The QWT21 automatic concrete block production line is comprised of batching and mixing system, forming system, delivery system, stacking system, and control system.

a. Batching and Mixing System
There are batching station, mixer, batching and weighing conveyor system, as well as cement weighing conveyor system.

b. Forming System
It is a Fixed type forming system.

c. Delivery System
The system covers the front conveyor, back conveyor, horizontal conveyor, cleaning device, elevator, lowerator, kiln rack, pallets turnover device, and pallet warehouse.

d. Stacking System
It includes the full-automatic palletizing machine, chain-plate conveyor, trays feeder, etc.

e. Control System
The QWT21 automatic concrete block production line has the molding control system, conveyor control system, batching and mixing control system, kiln rack control system, and automatic stacker control system.

2. Performance

We have developed the national top-grade QT9-20 block making machine which has the independent knowledge right. The equipment is of international advanced level.

b. Technical Features

1. The QWT21 automatic concrete block production line applies the sturdy, durable rack made of rectangular steel.
2. With the mandatory mechanical positioning function, the block making machine comes with high rate of finished products.
3. The batching and mixing system adopts the vertical planetary mixer. This mixer makes sure the consistency of the concrete blocks.
4. The block making machine is configured with the electrical components supplied by the world famous companies. It works stably and reliably.
5. The translational material distribution technology makes sure the fast, uniform material distributing. It is also one of the reasons that the production line can offer high output.
6. The variable frequency motor has greatly boosted the vibration motor efficiency, and decreased the energy consumption.
7. With the hydraulic braking device, the upper mold will not move upward when demoulding. Therefore, the concrete products will be prevented from being damaged.
8. A centering device guarantees the pallet on the accurate position of the vibration platform. It avoids the pallet drifting.
9. The built-in elevator makes the wet product leave the host machine and enter into the delivery system. So when delivering, the wet product damage resulted from pallets collision will be averted.
10. The hydraulic system applies the world well-known hydraulic components, ensuring the equipment stable operation.
11. The automatic palletizing machine applies a high-precision encoder to control the lifting of the palletizing clip. No brick dropping will occur.
12. The unattended kiln rack can safely, accurately transport the concrete product to the specified location. Due to the proximity switch induction system, it won’t be affected by the vapor inside the curing room. In addition, it has the safety protection facilities.
13. The twelve-floor elevator well matches with the twelve-floor kiln rack, so the workshop space can be made full use of. The elevator is stable, reliable in operation for the application of the reputable brand reducer.
14. It is equipped with the automatic fault diagnosis system. The production process can be monitored through the production process.
15. The whole machine has a long service life, since it is welded from super structural steel with international advanced technology.
16. A unique horizontal broaching device helps realize the automatic production of wall block. The advanced forming machine has a wider application range. It can be installed with different molds for making different concrete products.

5. Facilities

b. Water Consumption
Total Water Consumption = cement content × water cement ratio. For the dry and hard concrete, the water cement ratio ranges from 0.42 to 0.45. To produce 240×115×90mm perforated bricks for two shifts per day in 300 days, the water consumption will be 4,200 tons.

Water Requirement
Both potable running water and clean natural water can serve as the production water. The production water is required to contain no detrimental impurities, oil grease, saccharides, or other substances that will affect the cement normal hardening. Therefore, do not use sewage, industrial waste water, acid water with PH value below 4, as well as water with sulphate content of more than 1%.

Suggestions
Install a water magnetizing device onto the water pipe. The magnetized water can increase the concrete product compressive strength by 5% or so.

c. Vapor
If steam curing is needed, the pipe steam will be provided by the factory.
