Description

Technical Field

[0001] The utility model relates to the technical field of autoclaved aerated concrete blocks, and more specifically, to a slurry pouring device for autoclaved aerated concrete blocks. Background Technique

[0002] Autoclaved aerated concrete blocks are made from fly ash, lime, cement, gypsum, slag, etc. as the main raw materials, adding appropriate foaming agents, regulators, and bubble stabilizers, and going through processes such as batching, mixing, pouring, static stopping, cutting, and high-pressure steam curing. The construction characteristics of autoclaved aerated concrete blocks are also very excellent. It can not only produce various specifications in the factory but also be sawed, planed, drilled, and nailed like wood. Also, due to its relatively large volume, the construction speed is relatively fast, and it can be used as a filling material for general buildings. When pouring the slurry of autoclaved aerated concrete blocks on the market, there is a problem that air will be mixed into the slurry, resulting in the concrete slurry containing too large bubbles, which affects the quality of the blocks. For this reason, we propose a slurry pouring device for autoclaved aerated concrete blocks.

[0003] Regarding the above problems, for the technical problem of too large bubbles in the existing autoclaved aerated concrete blocks, after a large number of searches, a slurry pouring device for autoclaved aerated concrete blocks with the patent number CN217395226U was found. It includes a support and a vibration component. The top of the support is provided with a barrel, and the upper left end of the barrel is provided with a feed port. The central part of the top of the barrel is provided with a stirring motor, and the lower end of the stirring motor is connected with a stirring paddle. The central part of the bottom of the barrel is provided with a discharge pipe, and a solenoid valve is arranged in the center of the discharge pipe. Through the setting of the vibration component, when pouring the slurry, by starting the vibration motor, the carrier plate can vibrate under the action of the spring and the telescopic column, so as to vibrate and compact the slurry in the upper mold, discharge the large bubbles in the slurry, which is beneficial to improving the overall quality of the blocks. Also, through the setting of the positioning component, it is convenient to start the cylinder, so that the pressing plate moves to the left under the limit of the guide rod and the fixed plate, so as to cooperate with the limit plate to clamp the mold. However, the technical solution provided by this patent has the following problems:

[0004] (1) Springs are arranged at the bottom of the device. After a period of use, due to different degrees of spring aging, when subjected to the same force, the spring expansion and contraction degrees are different, resulting in the carrier plate connected to the top of the spring tilting to one side. The mold tilts together with the carrier plate, which will cause the slurry injection volume to be unqualified and lead to unqualified bricks manufactured.

[0005] (2) The manufacturing setup is equipped with an observation window to observe the situation of slurry injection. However, when injecting the slurry, the slurry will splash onto the observation window. Over time, this will cause a layer of slurry to cover the observation window, making it impossible to observe the slurry injection situation. Moreover, if the slurry is not cleaned in time, it will stick to the observation window and be difficult to clean thoroughly later.

[0006] The utility model can achieve the effects of eliminating large air bubbles in the slurry, automatically stopping the feeding, and adjusting the pouring amount of the slurry according to requirements. Summary of the Utility Model
