Description

Technical Field

[0001] The utility model relates to the technical field of concrete equipment, in particular to a valve-controlled concrete powder arch breaker. Background Art

[0002] Concrete powder refers to the fine powder made by grinding raw materials such as cement, limestone, slag, fly ash, coal ash, quartz powder, etc., which is one of the raw materials of concrete. Concrete is composed of raw materials such as cement, sand, gravel, powder, etc., and is a high-strength and high-durability building material formed after solidification and hardening. The concrete mixing station is mainly composed of five systems, namely the mixer, material weighing system, material conveying system, material storage system and control system, and their ancillary facilities. Among them, the material storage system includes a powder tank for storing powder. As an essential auxiliary equipment of the concrete mixing station, the powder tank is mainly used to store powder to meet the continuous production of the concrete mixing station. During use, if the powder is stored for a long time, the powder is damp, or the powder tank is not cleaned for a long time, an arch plug will often form at the cone part at the lower end of the powder tank, so that the upper powder in the bin cannot fall smoothly. Long-term use will cause the discharge port at the bottom of the powder tank to be blocked, affecting the production efficiency of the mixing station. If the discharge port is blocked and the powder cannot be discharged, the mixing station will not be able to produce normally, causing unnecessary losses to the concrete manufacturer. Since the powder tank is an enclosed structure as a whole and is high, it is difficult for people to enter. After the powder is stored in the tank, people are unable to enter to clean it. The currently commonly used method of breaking the powder arch mainly uses a flow-aiding air cushion or a flow-aiding air bowl to break the arch. A flow-aiding air cushion or a flow-aiding air bowl is installed on the inner wall of the cone at the lower end of the powder tank, which has a good arch breaking effect.

[0003] Existing technical problems: The existing powder tank will cause the air inlet to be blocked when not used for a long time or used frequently, thereby deteriorating the fluidity of the powdered cement, causing the powder to be transported unsmoothly and affecting production efficiency.
