Petroleum fracturing propping agent cleaning and screening device

Abstract

The invention discloses a cleaning and screening device for a petroleum fracturing propping agent. The cleaning and screening device comprises an ultrasonic cleaning pool, a cleaning roller, a drying device and a liquid supplementing device. A cleaning roller is arranged in the ultrasonic cleaning pool and comprises an outer screen drum and an inner screen drum which are coaxially arranged; an inclined downward barrel opening of the outer screen barrel is arranged in the ultrasonic cleaning pool, an inclined downward barrel opening of the inner screen barrel is arranged on the outer side of the ultrasonic cleaning pool, and inclined upward barrel openings of the outer screen barrel and the inner screen barrel are arranged on the outer side of the ultrasonic cleaning pool; an ultrasonic transducer is arranged below the outer screen drum in the ultrasonic cleaning pool; a proppant discharge port is formed below an upward inclined cylinder opening of the outer screen cylinder; an impurity discharge port is formed below an upward inclined cylinder opening of the inner screen cylinder; and a drying device is arranged on the outer side of the outer screen drum between the ultrasonic cleaning pool and the proppant discharge port. The device has the advantages that cleaning, screening and drying functions are integrated, manual participation is reduced, the repeated utilization rate of the petroleum fracturing propping agent is increased, and resource waste is reduced.

Description

Technical field: [0001] The invention relates to the field of cleaning and screening equipment, in particular to a cleaning and screening device for oil fracturing proppant. Background technique: [0002] Petroleum fracturing proppant is used in the process of oil and gas deep well mining. After the high closure pressure and low permeability deposits are fractured, the fractures formed after the fracturing of the ore deposits are guaranteed to open, so that oil and gas products can pass through smoothly; with the acceleration of modernization, The development of oil fields is becoming more and more powerful, and the demand for oil fracturing proppant is also extremely large, so the research on its reuse becomes very important. [0003] The existing oil fracturing proppant cleaning device only has a simple cleaning function, only put the workpiece to be washed into the drum, and use ultrasonic waves to clean the surface of the workpiece, but the oil fracturing proppant is att...

AI Technical Summary

Problems solved by technology

[0003] The existing oil fracturing proppant cleaning device only has a simple cleaning function, only put the workpiece to be washed into the drum, and use ultrasonic waves to clean the surface of the workpiece, but the oil fracturing proppant is attached to the surface, making cleaning difficult At present, there is no special equipment on the market for cleaning the oil stains attached to the surface of oil fracturing proppants, which makes it difficult to reuse oil fracturing proppants, resulting in waste of resources; the existing screening device uses a screw conveyor to pass through the screen during the transmission The net screens the workpiece and impurities, but the structure of the screening device is relatively complex and the efficiency is low; moreover, there is no device that combines cleaning and screening on the market. During the cleaning process, oil fracturing proppant and Large particles of impurities are screened, resulting in low reuse rate of oil fracturing proppant
