Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to an air pressure balancing device for concrete production. Background Art

[0002] Concrete is a commonly used building material, which is made by mixing and stirring cementitious materials (usually cement), aggregates (such as sand and gravel), water and admixtures in a certain proportion.

[0003] Storage tanks are required during the storage of concrete. In order to ensure the stability of concrete during storage, an air pressure balance device is usually installed on the surface of the tank. When the pressure in the tank is too high or too low, a pressure difference will be generated on the tank structure. This may cause deformation of the tank over a long period of time, affecting its service life and safety. A stable air pressure environment can reduce the evaporation and segregation of water in concrete during storage, thereby ensuring the uniformity of concrete quality.

[0004] The air pressure balance device installed on the surface of the existing concrete storage tank may be subject to collision and scratches of objects in the production environment. Therefore, the air pressure balance device needs to be protected. Protection can prevent the sensor housing from being damaged and affecting its measurement accuracy and stability. Therefore, a protective frame is usually used to protect the air pressure balance device. When the air pressure balance device in the protective frame works for a long time, the electronic components in the air pressure balance device will generate heat when working. If the heat cannot be dissipated in time, the component temperature may be too high, affecting its performance and stability, and even causing malfunctions. Therefore, a cooling fan and ventilation plate are installed in the protective frame. The ventilation plate is in the concrete production environment for a long time, and a large amount of dust will stick to the surface of the ventilation plate. Long-term adhesion will cause blockage of the ventilation plate, resulting in temperature imbalance of the electronic components in the air pressure balance device. To address this problem, we propose a concrete production air pressure balance device. Utility Model Content
