Solid waste crushing and screening skid-mounted equipment

Abstract

The invention discloses solid waste crushing and screening skid-mounted equipment. The solid waste crushing and screening skid-mounted equipment comprises a hopper, a roller screen communicated with a discharging hole of the hopper by virtue of a packing auger, a first conveyor belt communicated with a fine material discharging hole of the roller screen and a second conveyor belt communicated with a coarse material discharging hole of the roller screen, wherein a discharging end of the first conveyor belt is communicated with a material storage bin at the lower end of a crushing machine, a discharging end of the second conveyor belt is communicated with a feeding hole of the crushing machine. In a working process, materials enter a hopper, then is pushed into the roller screen by virtue of the packing auger below the hopper and is screened into a fine material with the particle size meeting the requirement and a coarse material with larger particle size under the action of a screen plate in the roller drum, the fine material directly enters the material storage bin at the lower end of the crushing machine when being driven by the first conveyor belt, the coarse material enters the crushing machine when being driven by the second conveyor belt and is further crushed by virtue of the crushing machine, and a small particle material is formed, so that the specification of the material can meet usage requirement.

Description

technical field [0001] The invention relates to the technical field of drilling assistance, in particular to a solid waste crushing and screening skid-mounted equipment. Background technique [0002] Drilling fluid is a circulating fluid used for drilling, and it is a circulating flushing medium used in the hole during the drilling process. Drilling fluid has the functions of carrying and suspending cuttings in the wellbore, balancing formation pressure, cooling and lubricating drill bits and drilling tools, protecting well walls and oil and gas layers, and increasing drilling speed. It plays a very important role in the drilling process. [0003] Drilling waste fluid (mud) is a multiphase stable colloidal suspension system, containing various inorganic salts, organic treatment agents, polymers, surfactants and other substances, which contain oils, salts, drilling fluid additives and some soluble The heavy metal ions pollute the soil and water, affect the growth of animals ...

AI Technical Summary

Problems solved by technology

[0004] Traditional mud treatment equipment can only realize simple filtration and solid-liquid separation of mud on the drilling platform, and the processing capacity is low, and the solid phase components generated by the treatment are piled up in the well site, occupying the space of the well site, and the solid phase cannot be realized. component reuse
