Description

Technical Field

[0001] This utility model relates to the field of building materials, and in particular to an AAC composite insulation board and its production equipment. Background Technology

[0002] Currently, most building exterior wall insulation systems employ a single-layer AAC substrate covered with EPS or rock wool boards. This system relies on on-site wet work, achieving its enclosure function through layer-by-layer application of adhesives, anchors, crack-resistant mortar, and finishing layers. However, it suffers from the following key drawbacks in engineering practice: Lack of structural integration: In traditional construction methods, the external insulation layer relies solely on adhesives and anchors to bear the load, which has a high risk of interface peeling, insufficient wind pressure and impact resistance, and makes it difficult to achieve coordinated load-bearing between insulation and structure. Production efficiency constraints: Traditional construction methods require on-site mixing and batching of materials, as well as multi-layer stacking, which are cumbersome processes and subject to environmental temperature and humidity constraints, making it impossible to achieve continuous factory production; while traditional mixing systems rely on stop-start batch operations, with obvious breaks in material conveying and molding cycle, which restricts the efficiency of large-scale production.

[0003] Although AAC composite insulation boards have advantages such as being lightweight, heat-insulating, and sound-insulating, the performance potential and economic benefits of existing technologies have not been fully realized due to the discreteness of structural design and the lack of continuity in production equipment.

[0029] The working principle of the mixing device in the AAC composite insulation board production equipment disclosed in this utility model is as follows: Cement, expandable polystyrene EPS particles, and additives (powder) are fed into the dry mixing chamber 119 in proportion through the feed port 125. Then, the pneumatic main drive motor 126 drives the dry mixing rotary blade 121 to rotate through the dry mixing shaft 120. The rotation of the dry mixing rotary blade 121 will stir and mix the cement, expandable polystyrene EPS particles, and additives (powder) inside the dry mixing chamber 119. During this process, the dry mixing rotary blade 121 will drive the mixture (cement, expandable polystyrene EPS particles, and additives (powder)) to move upward locally, and then fall back under the action of gravity. The whole mixture rotates and mixes inside the dry mixing chamber 119 (the cement, expandable polystyrene EPS particles, and additives (powder) at the bottom of the dry mixing chamber 119 are not mixed and need to be discharged last as waste, depending on the shape of the bottom of the dry mixing chamber 119). The rotation of the dry-mix rotary blade 121 causes the actuating plate 123 to swing through the actuating pin 122, which in turn causes the actuating plate 123 to move the cement, expandable polystyrene EPS particles, and additives (powder) locally, increasing their downward fluidity.

[0030] Each mixing session lasts no less than 5 minutes. Once mixing is complete (due to the multiple dry mixing rotary blades 121, and the different heights of each dry mixing rotary blade 121 inside the dry mixing chamber 119, the dry mixing rotary blades 121 at different heights mix the cement, expandable polystyrene EPS particles, and additives (powder) at the corresponding positions), when the mixture is fed into the spray chamber 108 from the dry mixing chamber 119 (vibration motors are installed at the bottom of the dry mixing chamber 119 and at the connection between the dry mixing chamber 119 and the spray chamber 108 to increase the fluidity of the mixture), cement, expandable polystyrene EPS particles, and additives (powder) can be continuously poured into the dry mixing chamber 119 to achieve continuous mixing), the electromagnet 134 is activated. The electromagnet 134 generates magnetic force, which magnetically attracts the friction disk 135, increasing the friction between the electromagnet 134 and the friction disk 135. Since the electromagnet 134 slides on the star-shaped support 133, the electromagnet 134 restricts the rotation of the friction disk 135. Furthermore, when the output shaft of the main drive motor 126 drives the dry mixing shaft 120 to rotate, the dry mixing shaft 120 also drives the first rotating shaft 128 to rotate via the first transmission belt 127. The first rotating shaft 128 drives the central gear 138 to rotate via the second transmission belt 129. The central gear 138 drives the planetary gear 137 to rotate on its own axis and revolve around the sun. (When the electromagnet 134 is not activated, there is a sliding fit between the electromagnet 134 and the friction disk 135, with only a small frictional force. At this time, the friction disk 135 is in a free rotation state. Therefore, the revolution of the planetary gear 137 will be applied to the friction disk 135. Since the gear ring disk 136 is the load end, when the electromagnet 134 is not activated, the power of the central gear 138 drives the friction disk 135 to rotate, but does not drive the gear ring disk 136 to rotate (the force that drives the gear ring disk 136 to rotate is greater than the sliding frictional force between the friction disk 135 and the electromagnet 134 (when not activated)). The planetary gear 137 drives the gear ring disk 136 to rotate. The rotation of the second shaft 131 is driven to rotate via the third transmission belt 130. The second shaft 131 then drives the water spray pipe shaft 116 to rotate via the fourth transmission belt 132 (the water spray pipe shaft 116 needs to be connected to a water pipe and supply water and liquid additives to its interior, and the water pressure is adjustable). The rotation of the water spray pipe shaft 116 will drive the scraper 117 to rotate (the scraper 117 is fixed on the water spray pipe shaft 116). The water spray pipe shaft 116 will also drive the drive on the rotating dial mounting plate 110 to rotate. The rotating deflector 109 and the wetted deflector 112 on the wetted deflector bracket 113 cause the rotating deflector 109 to rotate, which in turn causes the mixture falling into the spray chamber 108 to rotate. Therefore, the mixture (mixed cement, expandable polystyrene EPS granules, and additives (powder)) will move along the rotating deflector 109 towards the inner wall of the spray chamber 108 under the action of centrifugal force, and then fall downward into the wetted deflector 112. The wetted deflector 112 will also cause the mixture to continue to rotate.Simultaneously, water and liquid additives inside the spray pipe shaft 116 are sprayed onto the rotating mixture through the nozzle 115, ensuring thorough mixing of the mixture with water and liquid additives, resulting in a wet mixture. Under gravity, the mixture falls into the separation chamber 104. A portion that falls onto the cone 118 is scraped off by the scraper 117 and slides along the bottom of the separation chamber 104 and the discharge port 105 into the intermediate discharge transfer chamber 101 (where the vibrating motor increases fluidity). The mixture is then discharged into the discharge mixing and conveying pipe 102. The wet mixing motor 103 is then activated, and its output shaft drives the wet mixing rotating shaft 106 to rotate. All the wet mixing rotating blades 107 on the wet mixing rotating shaft 106 rotate (the wet mixing rotating blades 107 locally drive the mixing...). The material moves upward, but cannot resist the force of gravity, so the mixture generally flows downward. Its main function is to slow the downward flow of the mixture, ensuring that the mixture remains in the discharge mixing conveyor pipe 102 for at least five minutes. This specific time can be adjusted by controlling the output shaft speed of the wet mixing motor 103. The wet mixing motor 103 controls the rotation speed of the wet mixing rotary blade 107, thereby controlling the downward flow speed of the mixture: an increase in the speed of the wet mixing rotary blade 107 increases the resistance to the mixture, thus increasing the mixing time, and vice versa. The wet mixing rotary blade 107 continues to mix the wet-mixed mixture, while simultaneously, under the influence of gravity, it slides down the discharge mixing conveyor pipe 102 to the designated position. It should be noted that the length of the discharge mixing conveyor pipe 102 is not its actual length.
