Abstract
Description
Technical Field
[0001] This utility model belongs to the field of proppant production technology, specifically relating to an automatic batching device for proppant production. Background Technology
[0002] In the process of fracturing, in order to prevent the fractures from closing after the pump is stopped, solid particles are carried into the fractures by proppant fluid to support them. In order to make the fractures with high permeability after being filled with proppant, the proppant should have uniform particle size, high strength, low density, good sphericity, be easily carried by the fluid, be widely available and inexpensive. Propants used include: quartz sand, glass beads, ceramsite, walnut shells and aluminum balls, etc.
[0003] Currently, the various raw materials used to prepare proppant need to be mixed in a mixing device after being proportioned. However, the process of feeding the various raw materials into the mixing device through hoppers does not make it convenient to make good use of the waiting time to mix them in advance. As a result, it takes a long time to fully mix the raw materials in the mixing device, and the small amount of raw materials added may clump or be incompletely crushed, resulting in excessively large particle sizes. The participation of excessively large raw materials in the production and preparation of proppant will affect the product quality. Utility Model Content

A stirring mechanism is installed inside the first batching box 1, the second batching box 2, and the third batching box 3. The stirring mechanism includes a stirring rod 8, a first stirring blade 10, a second stirring blade 11, and a third stirring blade 12. The stirring rod 8 is installed inside the first batching box 1.
