Description

Technical Field

[0001] The utility model relates to the technical field of fracturing, in particular to a multi-stage material feeding structure. Background Art

[0002] In the preparation of sand-mixing fluid, sand is used as a fracturing proppant. After being processed, the sand is concentrated in a storage tank for standby use. When sand is needed, the sand is transported to the vertical elevator through a feeding mechanism arranged at the bottom of the storage tank, and then flows from the discharge pipe on the vertical elevator to the next process for processing. Since there are many processes using sand, when the sand flows out of the discharge pipe, it is necessary to branch multiple guide pipes on the discharge pipe, and then connect the guide pipes to different processes.

[0003] In order to accurately guide the sand into the corresponding process, a gate is provided on each branch pipe. By manually opening the gate on the branch pipe corresponding to the required process and closing other gates, the sand can be guided into the process. Sometimes, sand is required for multiple processes at the same time, and manual labor is required to climb onto the climbing frame and then open the corresponding gates, which is time-consuming and has low operating efficiency.
