Impeller type concrete flow metering device

Abstract

The invention discloses an impeller type concrete flow metering device. Air in the pipeline is exhausted through the arranged pressure relief exhaust pipe, the pressure of concrete in the pipeline is reduced, and the flow speed of the concrete tends to be stable; when concrete flows into a cavity formed by the two blades of the impeller and the shell, and the cavity is filled with the concrete, the concrete drives the impeller and the rotating shaft to rotate through the gravity of the concrete, and at the moment, the rotary encoder arranged at the first end of the rotating shaft obtains mechanical quantities such as angular displacement and angular speed of the rotating shaft; mechanical quantities such as angular displacement and angular speed are converted into corresponding electric pulse signals and then transmitted to the counter, and the counter converts the electric pulse signals transmitted by the rotary encoder into the pouring quantity of concrete in unit time and then transmits the obtained pouring quantity to the terminal equipment; and a worker can control the switch of the conveying pump according to the pouring amount of concrete, so that the problem of excessive or insufficient pouring of the concrete is avoided, and the construction efficiency of the concrete is ensured.

Description

technical field [0001] The invention relates to the construction field, in particular to an impeller type concrete flow metering device. Background technique [0002] At present, most of the reinforced concrete used in building construction adopts the traditional cast-in-place method, that is, the internal steel mesh is constructed first, and then the formwork is set up on the periphery of the steel mesh, and then concrete is filled into the gap between the steel mesh and the formwork. The integrated structure formed by hardened concrete and steel realizes the load-bearing and earthquake-resistant capacity of the building. In the process of cast-in-place, the concrete is regarded as a fluid, and the concrete is transported and poured relying on the thrust of the delivery pump and the pipeline. During the construction process of conveying to the front-end pouring, the current front-end construction method is to manually hug the hose outlet The distribution of materials is ma...
