[Abstract]:The main functions of sand mixer are mixing, stirring and conveying sand body for hydraulic fracturing. In the process of production well fracturing, the quality of the operation result is affected by whether some main parameters of the sand mixer meet the construction requirements. As the key component of the sand mixing truck, the main responsibility of the sand transportation system is to transport raw materials for the sand mixer. At the same time, the need for accurate measurement, whether accurate measurement will directly affect the results of the fracturing operation. Based on the analysis of the conveying principle and structural characteristics of the large inclination screw conveyor, this paper determines the influence of the parameters of the sand mixing vehicle: rotational speed, inclination angle, pitch, blade diameter and helical shaft diameter on the sand transport efficiency. By analyzing the vibration theory, the natural frequency and the disturbance degree of the helical shaft, the key component of the sand conveyer, are determined, and the strength and stability of the screw shaft are checked by the numerical analysis method. By comparing and analyzing the parameter selection scheme of screw conveyor under the condition of equal pitch and variable pitch, this paper optimizes the pitch of screw, and applies ANSYS software to analyze and discuss the dynamic performance and influence factors of the main structure of sand conveyer of sand mixing vehicle. By analyzing the influence of rotating speed, inclination angle, pitch, blade diameter and helical axis diameter on sand transport efficiency, and using orthogonal principle, the experimental scheme is designed, and the best scheme for improving sand transport efficiency is obtained.
