[0002] With the increasing demands for energy conservation, environmental protection, and comfort in the construction industry, thermal insulation bricks, as an important building material, are widely used in residential, office, and industrial buildings. Thermal insulation bricks not only possess excellent thermal insulation properties but also high compressive strength, durability, and good construction adaptability. Therefore, improving the production efficiency and quality of thermal insulation bricks has become a focus of industry attention.

[0003] Existing thermal insulation brick production processes mainly include raw material mixing, molding, and drying. Traditional production lines typically rely on manual operation, resulting in low efficiency and frequent quality instability. For example, uneven raw material mixing, inaccurate humidity control, and uneven drying all affect the final product quality and production efficiency. Furthermore, existing drying equipment is not ideal in terms of energy consumption and temperature control, leading to higher production costs and longer drying times.

[0004] Therefore, there is an urgent need for a new production line equipment that can effectively solve the above problems, realize the automation, intelligence and efficiency of the production process, and thus improve the production quality and efficiency of thermal insulation bricks.

The bottom of the mixing chamber is connected to the molding device and is conical with a control valve. The mixing chamber is equipped with a humidity sensor and a spraying device. The spraying device includes a spray pipe that runs through the mixing chamber and has several atomizing nozzles on its lower surface. The spray pipe is connected to a water supply mechanism and a regulating valve.

[0007] The drying device includes a drying chamber, which is a rectangular box structure. The frame of the drying chamber is made of steel, and the walls of the drying chamber are made of multi-layer thermal insulation panels. The drying chamber is equipped with a sealed door, and a sealing strip is provided at the connection between the sealed door and the drying chamber. An observation window is provided on the sealed door. The drying chamber is equipped with drying racks, which have several layers. Each layer is equipped with an independent heating device and a ventilation device. The bottom of the drying rack is equipped with rollers, and an intake fan and an exhaust fan are provided on the walls of the drying chamber.

[0008] As a further improvement, the mixing chamber is made of alloy steel, and the inner wall of the mixing chamber is coated with an anti-stick coating.

[0009] As a further improvement, the materials of the multi-layer thermal insulation partition are rock wool and aluminum silicate.

[0010] As a further improvement, the sealing door is a double-door structure, and the sealing door is connected to the drying chamber by a hinge, with a sealing strip between the two sealing doors.

[0011] As a further improvement, the heating device uses an electric heating or gas heating heat source, and the heating method is hot air circulation or electric heating plate heating.

[0012] Beneficial effects:

[0013] Improved production efficiency: This production line significantly improves the uniformity of raw material mixing through precise humidity control and a uniform mixing design, reducing manual intervention and increasing the level of automation. The use of variable frequency drives (VFDs) connected to motors for the mixing blades allows for adjustment of the mixing speed according to different materials, achieving optimal mixing results and thus improving production efficiency.

[0014] Precise humidity and moisture control: A humidity sensor and spray system are installed in the mixing unit to monitor the humidity of the mixed materials in real time and precisely adjust the addition of moisture to ensure consistent humidity in each batch. This design effectively avoids production instability caused by improper humidity control and improves the quality consistency of the insulation bricks.

[0015] Optimized drying effect: The drying unit of this production line adopts a multi-layer insulation partition structure, combined with independent heating and ventilation devices, which can ensure uniform circulation of hot air during the drying process, avoiding the uneven heat distribution commonly found in traditional drying systems. The design of the intake and exhaust fans effectively improves air circulation speed, shortens drying time, and reduces energy consumption.

[0016] Energy saving and consumption reduction: The drying unit adopts multi-layer insulation panels, such as rock wool and aluminum silicate, which effectively reduces heat loss and improves thermal efficiency, thereby reducing energy consumption. At the same time, the hot air circulation system of the drying unit is combined with the heating device, either electric or gas heating, to optimize the utilization efficiency of the heat source and further save energy.

[0017] Environmental protection and safety: The drying unit's sealed doors feature a double-door structure and are equipped with sealing strips, effectively preventing the leakage of external heat and reducing energy waste. Simultaneously, the drying chamber is equipped with observation windows, allowing operators to conveniently monitor the equipment in real time, ensuring personnel safety and normal equipment operation during production.

[0018] In summary, the thermal insulation brick production line of this utility model has multiple advantages such as high efficiency, energy saving, and environmental protection, which can significantly improve production efficiency and product quality, and meet the needs of the modern construction industry for high-performance building materials production.
