Description

Technical Field

[0001] This utility model relates to the field of quartz sand proppant production and application technology, and in particular to a belt conveyor network based on a multi-stage screening machine. Background Technology

[0002] Because the industrial application of quartz sand proppant has strict standards for particle size, during the preparation and production process of quartz sand proppant, it is necessary to use a screening machine (drum screen) to segment the crushed quartz sand proppant through screens of different aperture sizes, and automatically divide it into multiple grades (such as coarse sand, medium sand, and fine sand) according to the particle size range to meet the needs of different downstream applications.

[0003] However, after using a screening machine to separate quartz sand proppant into coarse sand, medium sand, and fine sand, it is difficult to collect quartz sand proppant of different particle sizes, which in turn affects the screening efficiency of quartz sand proppant. Utility Model Content

[0015] The core of this application is to provide a belt conveyor network based on a multi-stage screening machine, which solves the problem that after using a screening machine to separate quartz sand proppant into coarse sand, medium sand and fine sand, it is difficult to collect quartz sand proppant of different particle sizes, thus affecting the screening efficiency of quartz sand proppant.

[0017] Example 1 A belt conveyor network based on multi-stage screening machines includes multiple conveyor belts 2 positioned below multiple screening machines 1. The screening machines 1 screen silica sand proppant. Multiple discharge hoppers 3 are located at the bottom of the outer frame of each screening machine 1. The mesh size of the drum screens in the screening machines 1 increases sequentially from front to back. After screening, silica sand proppant with different particle sizes falls into the corresponding discharge hoppers 3. Each discharge hopper 3 is connected to a discharge pipe 4 at its bottom. The lower end of each discharge pipe 4 is located above the conveyor belts 2. Conveyor belts 2 of the same grade... A transfer belt 5 is connected to the front end of the conveyor belt 2, and its direction is perpendicular to that of each conveyor belt 2. The quartz sand proppant falling into the discharge hopper 3 can fall through the discharge pipe 4 onto the corresponding conveyor belt 2, and finally be transferred to the corresponding position by the corresponding transfer belt 5. In actual design, multiple conveyor belts 2 can correspond to the discharge hopper 3 collecting quartz sand proppant of the same particle size. The conveyor belts 2 collecting quartz sand proppant of different particle sizes run in opposite directions to facilitate the setting and operation of the transfer belts 5. The specific design can be determined according to the actual site conditions. (Appendix) Figure 1 For ease of observation, only one conveyor belt 2 is shown below the discharge hopper 3 for collecting particles of the same size. A conveyor belt 7 is installed at the rear discharge end of the screening machine 1 via a discharge chute 6. After screening, the coarse material discharged from the rear end of the screening machine 1 can fall along the discharge chute 6 onto the conveyor belt 7 for transport. This allows for the individual transport and collection of quartz sand proppant of different particle sizes.
