The previous text introduced the raw material pre-treatment system of the aerated block/slab production line. This article will introduce the batching, pouring, and mixing control system of the aerated block production line. The batching, pouring, and mixing control system mainly consists of a pouring mixer, an automatic aluminum powder metering device, and a bubble sorting machine. Below is a detailed introduction.

Pouring Mixer

The pouring mixer uses a spiral mixer (patented technology from Nepal). The spiral blades combined with the backflow cylinder cause the slurry to tumble up and down, resulting in a more uniform mixture and achieving an excellent mixing effect. The pouring mixer is located above the mold and is one of the important pieces of equipment in the production line, directly determining the quality of the product's formation.

Main Features:

The mixer uses a cross spiral blade mixer, which has a long lifespan, low failure rate, fast mixing speed, and uniform mixing.

The mixer adopts a four-point shock absorption system, resulting in low vibration during mixing.

It uses an improved flow guiding cylinder with four baffle plates on the inner wall, preventing dry materials from clogging, ensuring more uniform mixing, improving discharge efficiency, and shortening the pouring cycle to ensure that the mold box pouring is completed within 5 minutes.

The discharge uses a lifting pouring method to ensure the pouring environment and reduce the impact of the slurry on the mold release oil and the generation of large bubbles during pouring.

The motor uses a high-efficiency energy-saving motor, which can achieve variable frequency speed regulation, saving an average of about 5% energy.

Main Technical Parameters:

Capacity: 5.2m3 Power: 55KW

　　Automatic Aluminum Powder Metering Device

The GY-300I type automatic aluminum powder paste adding equipment adopts a dry powder one mold one metering method, with automatic operation from aluminum powder paste feeding, metering, water addition, mixing, to aluminum powder liquid discharge. This equipment features a unique discharge mechanism, high-precision weighing sensors, and intelligent control software, effectively solving the issues of low aluminum powder paste usage and high precision requirements. This device serves as an independent unit in the batching system, capable of running automatically in parallel with the original system or operating independently.

Equipment Features:

(1) High Precision: Precision control within ±5 grams. Suitable for aluminum powder paste of various viscosities. It uses weight reduction metering, eliminating the problem of aluminum powder paste sticking to the scale.

(2) Large Capacity: A single filling can basically meet the aluminum powder paste usage for one shift. The standard configuration aluminum powder paste storage tank has a volume of about 500 liters.

(3) Stable Performance, Easy Maintenance: Low operating costs with PLC program control, simple structure, and complete various alarm functions. The total power consumption is about 0.6kw/h.

(4) Good Mixing Effect: The mixing tank has a conical bottom design, automatically adds water, and adds aluminum powder while mixing, ensuring uniform mixing and rapid discharge.

(5) Uses PLC control with a human-machine interface to complete calibration, parameter setting, and other tasks.

Bubble Sorting Machine

During the pouring process, a lot of air is brought into the slurry. During the formation of the blank, these air bubbles cannot escape, leading to various irregular pore structures, ultimately resulting in uneven product strength and affecting the appearance quality of the product. The principle is to use gas, liquid, or electric actuators to drive a set of inserted vibrating rods installed on a planar linkage bracket, which vibrate the slurry and stop vibrating according to the instructions from sensors and control switches. Different forms of bubble sorting machines can be designed based on different process layouts. For pouring stations located on the ground, fixed brackets can be set up at suitable positions to install the bubble sorting machine. The bubble sorting machine can also be directly integrated with the pouring machine.

Main Features: The bubble sorting machine is equipped with twenty high-frequency vibrators.
