Fixed-torque concrete mixer and concrete mixing method

Abstract

The invention discloses a fixed-torque concrete mixer and a concrete mixing method, and relates to the technical field of concrete mixing. The fixed-torque concrete mixer comprises a mixing tank, wherein a bottom cover is arranged at the bottom of the mixing tank; a mixing cover is arranged at the top of the mixing tank; a torque converter is arranged at the top of the mixing cover; and a torque converter rotating shaft is arranged at the power input end of the torque converter. According to the fixed-torque concrete mixer and the concrete mixing method, rigid connection between the mixing shaft and a motor is replaced with fixed-torque connection, and the viscosity of various concrete grout can be detected by monitoring the rotating speed and torque of the motor under a certain torque, and the quality of the subsequent concrete grout is judged by referring to the viscosity; and meanwhile, when the viscosity of the concrete grout is too high, the fixed-torque device can enable the motor to idle so as to prevent the motor from being overloaded.

Description

technical field [0001] The invention relates to the technical field of concrete mixing, in particular to a constant moment concrete mixer and a concrete mixing method. Background technique [0002] Cement concrete mixers are widely used in my country's industrial, agricultural, transportation, water conservancy, municipal and other construction projects, and the demand is constantly increasing. Although domestic concrete mixing equipment continues to innovate and progress on the basis of learning from foreign products, and the technical level is gradually improved, as far as the entire mixing plant is concerned, the research on the batching process is still insufficient, especially for newly-built concrete mixing plants, which often rely on supporting manufacturers for many years The accumulated experience basically meets the quality requirements of the national standard for concrete mixing plants, and no special experimental research has been carried out on its conveying pr...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a constant-moment concrete mixer and a concrete mixing method, which solves the problem of motor overload due to the rigid connection between the stirring shaft and the motor when the viscosity of the concrete slurry is too high, and also solves the problem of concrete slurry The problem that the viscosity cannot be quantitatively detected
