[0057] The specific composition and workflow of the equipment used in each station in the utility model are as follows:

[0058] 1. Foaming equipment uses special chemical foaming agents to generate foam and output through precise metering and mixing technology, and ensures uniformity and stability during output.

[0059] (1) Foaming equipment includes: independent silos, such as silos for chemical foaming agents, foam stabilizers, and other additives; water diversion system (with automatic metering, heating, etc.); stirring silo; physical foaming system; and foam output system with automatic weighing (metering).

[0060] (2) Specific working process of foaming equipment: 1. Through the independent silos in the foaming system, the special chemical foaming agent, foam stabilizer, additive and other silos are automatically weighed as needed and then transported into the mixing silo in the foaming system; 2. Through the water supply system in the foaming system, water is automatically weighed or measured as needed and transported into the mixing silo in the foaming system. The water supply system has a heating function. When the water temperature is low, the water is automatically heated to the specified water temperature and then transported into the mixing silo; 3. The special chemical foaming agent, foam stabilizer and other additives are mixed with water in the mixing silo to form a foam solution. The physical foaming system (air compression foaming physical foaming principle) is used to make the foam solution into foam, and the foam state formed is detected in real time until the requirements are met; 4. The foam output system automatically weighs and measures the foam to output the foam accurately, evenly, stably and with controllable loss.

[0061] 2. Mixing equipment: Use a low-speed mixer to fully mix foam, cement, mortar, fiber and other raw materials and maintain uniform quality.

[0062] (1) Mixing equipment includes: independent silos, such as cement, silica fume, fiber, etc.; water diversion system (with automatic weighing, metering, heating, etc.); mixing silo. The mixing system is a special foam concrete mixing equipment, which uses horizontal longitudinal rotating blades for mixing. During the mixing process, the foam concrete is in the form of slurry (without coarse aggregate). The mixing blades need to be close to the bottom of the mixing silo to ensure that the slurry at the bottom of the mixing silo is driven as much as possible during the mixing process to ensure that it is mixed evenly.

[0063] (2) Specific working process of mixing equipment: 1. Through the independent silos in the mixing system, cement, silica fume, fiber and other materials are automatically weighed and measured as needed and then transported into the mixing silo in the mixing system; 2. Through the water diversion system in the mixing system, water, water reducer, defoamer and other liquids are automatically weighed and measured as needed and transported into the mixing silo in the mixing system, and stirred for a certain period of time as required; 3. Through the foam output system in the foaming system, the foam is automatically weighed and measured and transported into the mixing silo in the mixing system for mixing and stirring;

[0064] (3) It is worth noting that: 1. To ensure uniform mixing of concrete slurry and foam, the mixing chamber in the mixing system is continuously stirred during the working process of step 3. After the (wet) bulk density of the mixed foam concrete material meets the requirements, the mixing and stirring is stopped and the material is poured. 2. In order to ensure that the foam dissipates too much due to the too fast stirring blade speed during the mixing process, a low-frequency uniform speed agitator should be used.

[0065] 3. Casting equipment: Using automatic control technology, it can automatically identify the mold size or component drawings of the prefabricated lightweight concrete self-insulating exterior wall panels and then accurately cast them according to the set route to ensure product consistency.

[0066] (1) Casting equipment includes: a casting silo with automatic weighing and metering functions, display of cast volume, unused volume, etc., and real-time display; a sensor detection function for identifying the structure and shape of the mold to be cast; an assembly line casting platform with a vibration function; and a static molding station for smoothing the surface of the foam concrete.

[0067] (2) Specific working process of pouring equipment: (1) Through the pouring silo, it is automatically or manually controlled by a special track to travel to the mixing system, and the foam concrete in the mixing silo of the mixing system is transported into the pouring silo of the pouring system. (2) The pouring silo moves automatically to the top of the pouring platform of the assembly line through the track, and pours the foam concrete according to the precise pouring route obtained after automatic identification based on the precast panel mold and component drawings, forming a precast lightweight concrete self-insulating exterior wall panel. After pouring, the mold with the finished pouring is vibrated together with the platform, and the vibration frequency and amplitude can be adjusted automatically. After the vibration is completed, it is moved to the static forming station. (3) A special finishing machine is used, which can be automatically or manually operated to automatically collect water and finish the precast lightweight concrete self-insulating exterior wall panel, and then moved to the maintenance system after initial setting.

[0068] 4. Finished product curing area equipment: By controlling parameters such as humidity, temperature and time, the prefabricated lightweight concrete self-insulating exterior wall panels can be cured under optimal conditions to accelerate the curing process.

[0069] (1) Equipment in the finished product curing area includes: a closed curing space with an automatic door for access to the platform; a curing system that can precisely control temperature and humidity through nozzle fans and temperature and humidity sensors to keep the temperature rising or falling; and an automatic platform management system that can monitor and move each platform and automatically transport the platform out of the curing system after curing is completed.

[0070] (2) Specific work flow of the equipment in the finished product curing area: (1) After the prefabricated lightweight concrete self-insulating exterior wall panels have completed water absorption, the platform with the prefabricated lightweight concrete self-insulating exterior wall panels will be moved into the curing system. (2) The curing system adjusts the temperature and humidity for curing according to the different curing processes set by the user. (3) After the curing of the prefabricated lightweight concrete self-insulating exterior wall panels is completed, the curing system will display that the curing of the platform is completed, and the operator will arrange for the platform to be moved out of the curing system and the demoulding will be arranged.
