Technical Field

[0001] The utility model relates to the technical field of concrete blocks, in particular to a moisture content control device for autoclaved aerated concrete blocks. Background Art

[0002] Autoclaved aerated concrete blocks are a type of porous concrete product made from fly ash, lime, cement, gypsum and slag as main raw materials, with appropriate amounts of gas-generating agents, regulators and bubble stabilizers added, and are made through processes such as batching, mixing, pouring, static stopping, cutting and high-pressure steaming. The construction characteristics of autoclaved aerated concrete blocks are also very good. Not only can it be produced in various specifications in the factory, it can also be sawed, planed, drilled and nailed like wood. Due to its relatively large volume, the construction speed is also relatively fast, and it can be used as a filling material for general buildings. Autoclaved aerated concrete blocks need to be moderately moistened before masonry to maintain an appropriate moisture content. Therefore, the moisture content of autoclaved aerated concrete blocks needs to be controlled before masonry.

[0027] like Figure 1-4 As shown, a water spray assembly 4 is provided on the top of the water spray outer frame 3 for spraying water on the autoclaved aerated concrete blocks. The water spray assembly 4 includes a water storage cylinder 41, which is fixedly arranged at the top center of the water spray outer frame 3. A T-shaped connecting pipe 42 is fixedly provided on the top of the inner top of the water spray outer frame 3, and the top of the T-shaped connecting pipe 42 passes through the water spray outer frame 3 and is fixedly connected to the water storage cylinder 41. The T-shaped connecting pipe 42 and the water storage cylinder 41 are interconnected to facilitate the water inside the water storage cylinder 41 to flow into the T-shaped connecting pipe 42. A first electric valve 43 is fixedly provided on the top of the T-shaped connecting pipe 42, and a cylinder door 44 is provided on the top cover of the water storage cylinder 41 to facilitate opening the first electric valve 43 to discharge the water inside the water storage cylinder 41.

[0028] like Figure 1-5 As shown, three groups of control components 5 are provided inside the water spray outer frame 3 for accurately controlling the moisture content in the autoclaved aerated concrete blocks. The control component 5 includes a U-shaped water spray frame 51, which is provided inside the water spray outer frame 3 and on the top of the conveyor 2. A number of evenly distributed high-pressure nozzles 52 are fixed on the inner wall of the U-shaped water spray frame 51, and the high-pressure nozzles 52 are interconnected with the interior of the U-shaped water spray frame 51. The control component 5 also includes an electric telescopic rod 56, and the electric telescopic rod 56 is fixed to the inner wall of the rear side of the water spray outer frame 3.

[0029] A humidity sensor 57 is fixed to the front end of the electric telescopic rod 56, and a same opposing photoelectric switch 55 is fixed between the front and rear sides of the U-shaped water spray frame 51 (the opposing photoelectric switch 55 includes a transmitter and a receiver, and the transmitter and the receiver are respectively fixed on the bottom of the front and rear side walls of the U-shaped water spray frame 51). A connecting pipe 53 is fixed to the top of the U-shaped water spray frame 51, and a second electric valve 54 is fixed on the connecting pipe 53. The top ends of the three connecting pipes 53 are fixed to the bottom of the T-shaped connecting pipe 42, so as to accurately ensure that the moisture content of the autoclaved aerated concrete blocks is qualified. A control panel 6 for controlling the operation of the first electric valve 43, the second electric valve 54, the opposing photoelectric switch 55, the electric telescopic rod 56 and the humidity sensor 57 is fixed to the front side of the driving frame 1.

[0030] By setting the water spray component 4, the autoclaved aerated concrete blocks that need to be sprayed with water are placed at one end of the top of the conveyor 2, and then the control panel 6 is operated to control the conveyor 2 to transport the autoclaved aerated concrete blocks. When the autoclaved aerated concrete blocks on the top of the conveyor 2 pass through the bottom of a group of control components 5, the photoelectric switch 55 at the bottom end of the U-shaped water spray frame 51 (when the autoclaved aerated concrete blocks enter the light path between the transmitter and receiver of the photoelectric switch 55, the light beam will be blocked, causing the receiver to be unable to receive the light signal, which will indicate that the autoclaved aerated concrete blocks have been detected. On the contrary, when When the autoclaved aerated concrete block leaves the optical path, the light beam is received by the receiver again, indicating that no object has been detected. That is, the presence of the autoclaved aerated concrete block is detected by the through-beam photoelectric switch 55, which sends a signal to the control panel 6. The control panel 6 then controls the cylinder door 44 and the second electric valve 54 in the group to open, allowing the water in the water storage cylinder 41 to flow through the T-shaped connecting pipe 42 into the group of connecting pipes 53 and reach the group of U-shaped water spray frames 51. The water is then sprayed out by the multiple high-pressure nozzles 52 to spray the autoclaved aerated concrete block, ensuring that the water is sprayed evenly on the surface of the autoclaved aerated concrete block.

[0031] After one water spraying is completed, the autoclaved aerated concrete block continues to be transported by the conveyor 2. When the photoelectric switch 55 in the group can no longer detect the position of the autoclaved aerated concrete block, the control panel 6 will control the electric telescopic rod 56 to drive the humidity sensor 57 to extend and retract, so that the humidity sensor 57 contacts the inside of the autoclaved aerated concrete block after the water spraying to detect the humidity, thereby making it easier for the humidity sensor 57 to directly contact the autoclaved aerated concrete block and facilitate accurate moisture content detection of the autoclaved aerated concrete block.

[0032] After the moisture content test is qualified, the subsequent two groups of control components 5 on the top of the conveyor 2 will no longer work, and the conveyor 2 will complete the transportation of the autoclaved aerated concrete blocks with qualified moisture content; after the moisture content test is unqualified, the subsequent two groups of control components 5 can spray water on the surface of the autoclaved aerated concrete blocks again until the moisture content test of the autoclaved aerated concrete blocks is qualified, thereby ensuring the quality of the autoclaved aerated concrete blocks with qualified moisture content, realizing automatic control, and easy use.
