ABSTRACT
Aiming at the problems of uneven mixing and poor remediation effect of organic fertilizer remediation machines for petroleum-contaminated soil, this paper designs a solid-liquid fertilizer mixing device for petroleum-contaminated soil organic fertilizer remediation machine. According to particle size analysis of various organic particles and viscosity determination result of solid-liquid mixture, anchor-frame mixer is determined as the basic structure of solid-liquid mixing device. Orthogonal design method was used to design the best reasonable dimension parameter in order to explore solid-liquid mixing uniformity mechanism under the working condition of mixer and determine the best dimension parameter and working state parameters. The experimental results are basically consistent with numerical simulation results. Designed mixer meets the requirements of organic fertilizer solid-liquid mixed. The content of this paper refers theoretical basis for the design of a type organic fertilizer remediation machine.
