Description

Technical Field

[0001] The utility model relates to the technical field of batching scales for mixing stations, in particular to a maintenance-free and drag-proof water scale for a concrete mixing station. Background Art

[0002] Cement concrete mixing stations are widely used in my country's industrial, agricultural, transportation, national defense, water conservancy, municipal and other construction projects, and the demand is increasing. Although domestic concrete mixing equipment has been continuously innovating and improving on the basis of learning from foreign products, and the technical level has been gradually improved, the research on the batching process of the entire mixing station is still insufficient, especially for newly built concrete mixing stations, which often rely on the experience accumulated by supporting manufacturers over the years to basically meet the national standards for the quality requirements of concrete mixing stations, and no special experimental research has been conducted on its transportation process, feeding process, etc.

[0003] When the existing water scale is used to add materials after the measurement is completed, the water in the scale bucket and the pipeline flows into the mixer. After the feeding is completed, the drain valve of the water scale is closed, and the scale bucket and the pipeline are in a semi-vacuum negative pressure state. When the water in the pipeline continues to flow into the mixer under the action of gravity, the drain hose contracts, thereby generating a downward pulling force on the scale bucket, resulting in a larger measurement value for the next plate, thereby reducing the measurement accuracy.

[0004] In the patent case with the publication number CN213617587U, a maintenance-free and drag-proof water scale for concrete mixing stations is proposed. Through the air intake filter part, the air intake filter part includes a filter screen, the filter screen is located in the drainage hard pipe, and an impurity temporary storage chamber is provided on one side of the filter screen. The impurity temporary storage chamber is connected to the drainage hard pipe and the connection port is located at the top of the filter screen. The bottom of the impurity temporary storage chamber is provided with a discharge door that can be opened and closed. The top of the impurity temporary storage chamber is provided with an air intake pipe, the top of the air intake pipe is higher than the highest liquid level of the liquid in the scale bucket, and the air intake pipe is provided with an air intake valve. When feeding, the sand and stone mixed in the water are intercepted by the filter screen of the utility model, which prevents impurities from causing damage to the water pump; the pipeline is always connected to the external atmosphere through the air intake pipe, which avoids the formation of negative pressure in the pipeline, thereby avoiding the phenomenon of pulling the scale bucket and improving the measurement accuracy.
