Description

Technical Field

[0001] The present invention relates to the technical field of thermal insulation boards, in particular to an autoclaved aerated concrete composite thermal insulation board and a production process thereof. Background Art

[0002] The most common approach in current autoclaved aerated concrete exterior wall insulation systems is to bond polystyrene or rock wool boards to a single layer of autoclaved aerated concrete, then complete the enclosure with anchor bolts, crack-resistant mortar, and a surface finish system. However, this "wet work + multi-layer stacking" method has several key drawbacks: Continuous production is difficult, requiring numerous on-site batching steps and significantly impacted by temperature and humidity, making continuous, large-scale factory production impossible. The traditional exterior insulation layer relies solely on adhesives and anchors to withstand its own weight and wind loads, resulting in a high risk of interface delamination and difficulty balancing impact and crack resistance. The traditional mixing device's stop-and-start batch operation significantly limits the production cycle of existing technologies. Summary of the Invention

The top of the water spray pipe shaft 116 passes through the rotary dial plate mounting plate bracket 111 and is fixedly matched with the rotary dial plate mounting plate 110, and a plurality of nozzles 115 are provided on the water spray pipe shaft 116.

All the wetted dial plates 112 are fixed on the wetted dial plate bracket 113, and the wetted dial plate bracket 113 is fixed on the water spray pipe shaft 116. The bottom end of the water spray pipe shaft 116 extends to the bottom of the separation chamber 104 for connection to a water pipe (the water pipe and the water spray pipe shaft 116 are connected by a rotatable sealing joint).The discharge intermediate transfer chamber 101 is connected to the interior of the separation chamber 104 through the discharge port 105, and the discharge stirring and conveying pipe 102 is connected to the interior of the discharge intermediate transfer chamber 101, wherein the discharge stirring and conveying pipe 102 is inclined, and a wet mixing rotating shaft 106 is rotated inside the discharge stirring and conveying pipe 102, and a plurality of wet mixing rotating blades 107 are fixedly installed on the wet mixing rotating shaft 106, and the wet mixing rotating blades 107 are arranged in an axially equidistant array along the wet mixing rotating shaft 106, and a wet mixing motor 103 is fixedly installed on the outer surface of the discharge stirring and conveying pipe 102, and the output shaft of the wet mixing motor 103 extends to the interior of the discharge stirring and conveying pipe 102 and is fixed to the wet mixing rotating shaft 106. A first rotating shaft 128 and a second rotating shaft 131 are also rotatably mounted on the main bracket 114, wherein the top end of the first rotating shaft 128 is transmission-connected to the portion of the dry mixing shaft 120 located outside the top buckle cover 124 via a first transmission belt 127, the output shaft of the main drive motor 126 is fixedly matched with the top end of the dry mixing shaft 120, and the bottom end of the second rotating shaft 131 is transmission-connected to the water spray pipe shaft 116 via a fourth transmission belt 132.

The central gear 138 rotates in conjunction with the center position of the star bracket 133. The central gear 138 and the gear ring disk 136 are meshed and transmitted through planetary gears 137. The planetary gears 137 are rotatably mounted on the friction disk 135. The friction disk 135 is rotatably mounted on the inner side of the star bracket 133, and the central gear 138 rotates in conjunction with the friction disk 135. A slide groove is provided on the star-shaped bracket 133 along the axial direction of the water spray chamber 108, and an electromagnet 134 is slidably installed in the slide groove. The electromagnet 134 and the friction disk 135 are magnetically friction-engaged. The bottom end of the first rotating shaft 128 is connected to the central gear 138 through the second transmission belt 129, and the top end of the second rotating shaft 131 is connected to the gear ring disk 136 through the third transmission belt 130.

[0026] The working principle of the stirring device in the production process provided by the present invention 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, and then the pneumatic main drive motor 126 is driven. The output shaft of the main drive motor 126 drives the dry mixing rotating blade 121 to rotate through the dry mixing shaft 120. The rotation of the dry mixing rotating 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 rotating 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, and the entire mixture rotates, stirs, 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 therefore need to be discharged as waste at the end, depending on the shape of the bottom of the dry mixing chamber 119). The rotation of the dry mixing rotating blade 121 will cause the toggle plate 123 to swing through the toggle pin 122, so that the toggle plate 123 drives the cement, expandable polystyrene EPS particles, and additives (powder) to move locally, thereby increasing their downward fluidity.

[0027] Each mixing and stirring time is no less than 5 minutes. When the mixing is completed (due to the provision of multiple dry mixing rotating blades 121, and each dry mixing rotating blade 121 is located at a different height inside the dry mixing chamber 119, the dry mixing rotating blades 121 at different heights stir the cement, expandable polystyrene (EPS) particles, and additives (powder) at corresponding positions. Therefore, when the dry mixing chamber 119 sends the mixture into the water spraying chamber 108 (a vibration motor is provided at the bottom of the dry mixing chamber 119 and at the connection between the dry mixing chamber 119 and the water spraying chamber 108 to increase the fluidity of the mixture), cement, expandable polystyrene (EPS) particles, and additives (powder) can continue to be poured into the dry mixing chamber 119 to achieve a continuous stirring function), the electromagnet 134 is activated, and the electromagnet 134 generates a magnetic force, magnetically attracting the friction disk 135, thereby increasing the friction between the electromagnet 134 and the friction disk 135. Since the electromagnet 134 slides on the star-shaped bracket 133, the electromagnet 134 restricts the rotation of the friction disk 135. 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 through the first transmission belt 127. The first rotating shaft 128 drives the central gear 138 to rotate through the second transmission belt 129. The central gear 138 drives the planetary gear 137 to rotate and revolve (when the electromagnet 134 is not started, the electromagnet 134 and the friction plate 135 are in a sliding fit, with only a small friction force. At this time, the friction plate 135 is in a free rotation state, so the revolution of the planetary gear 137 will be applied to the friction plate 135. Since the gear ring plate 136 is the load end, when the electromagnet 134 is not started, the power of the central gear 138 drives the friction plate 135 to rotate, but does not drive the gear ring plate 136 to rotate (the force driving the gear ring plate 136 to rotate is greater than the sliding friction force between the friction plate 135 and the electromagnet 134 (when not started)).), the planetary gear 137 drives the gear ring plate 136 to rotate, and the gear ring plate 136 The rotation of the water pipe shaft 116 drives the second rotating shaft 131 to rotate through the third transmission belt 130, and the second rotating shaft 131 drives the water pipe shaft 116 to rotate through the fourth transmission belt 132 (the water pipe shaft 116 needs to be connected to the water pipe, and water and liquid additives are supplied to the inside of the water pipe shaft 116, and the water pressure of the supply is adjustable). The rotation of the water pipe shaft 116 drives the scraper 117 to rotate (the scraper 117 is fixed to the water pipe shaft 116), and the water pipe shaft 116 also drives the driving rotating plate on the rotary dial mounting plate 110 The paddle 109 and the wet paddle 112 on the wet paddle bracket 113 rotate. Driving the rotating paddle 109 to rotate will drive the mixture falling into the water spray chamber 108 to rotate. Therefore, the mixture (mixed cement, expandable polystyrene EPS particles, additives (powder)) will move along the driving rotating paddle 109 toward the inner wall of the water spray chamber 108 under the action of centrifugal force, and then fall downward into the wet paddle 112. The wet paddle 112 will also drive the mixture to continue rotating.At the same time, the water and liquid additives inside the water spray pipe shaft 116 will be sprayed toward the rotating mixture through the nozzle 115, so that the mixture is fully mixed with the water and liquid additives, and becomes a wet mixed state, and then falls into the separation chamber 104 under the action of gravity, and the part that falls on the cone 118 will be scraped off by the scraper 117, and then slide along the bottom of the separation chamber 104 and the discharge port 105 to the discharge intermediate transfer chamber 101 (wherein the vibration motor plays the role of increasing fluidity), and is discharged into the discharge stirring conveying pipe 102 through the discharge intermediate transfer chamber 101, and the wet mixing motor 103 is started. The output shaft of the wet mixing motor 103 drives the wet mixing rotating shaft 106 to rotate, and all the wet mixing rotating blades 107 on the wet mixing rotating shaft 106 rotate (the wet mixing rotating blades 107 will drive the mixing locally). The mixture moves upward, but cannot resist the effect of gravity, so the mixture as a whole still flows downward, which mainly slows down the speed of the mixture flowing downward, so that the mixture stays in the discharge mixing and conveying pipe 102 for no less than five minutes. The 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 rotating blade 107, thereby controlling the speed of the mixture flowing downward: the increase in the speed of the wet mixing rotating blade 107 increases the obstruction effect on the mixture, and the mixing time will increase, and vice versa. The wet mixing rotating blade 107 continues to stir the wet mixed mixture, and at the same time, under the action of gravity, it slides downward along the discharge mixing and conveying pipe 102 to a specified position. It should be noted that the length of the discharge mixing and conveying pipe 102 is not the actual length.
