Drilling Sludge Treatment Decanter Centrifuge

Drilling Mud Decanter CentrifugeThe Explosion-Proof drilling mud decanter centrifuge is manily used to dehydration for the all kinds of sludge and the drilling mud in oilfield. Drilling well solids control Centrifuge is the key equipment in treatment of harmful superfine solid in drilling liquid. remove harmful fine drill solids such as debris, etc. in the mud fluid, or recover weighting materials such as barite etc. so as to reduce the cost of mud fluid.Products DescriptionThe high speed variable-frequency horizontal spiral Drilling mud centrifuge is a specialized equipment primarily used for solid-liquid separation in the petroleum drilling fluid industry. The machine is a new product developed to absorb the advantages of foreign centrifuges and according to the rapid development of China's oil drilling centrifuges. It processes a large volume of light weight mud systems, and the processing volume should be appropriately reduced in heavy mud systems. In heavy mud systems, it can quickly recover heavy components such as barite to rapidly reduce the mud density. It is capable of efficiently removing harmful solid phases in deep and complex wells, and the rotational speed can be adjusted according to drilling needs, ranging from 0 to 3000 rpm, to find the appropriate speed based on mud particle size and density.According to different rotating speed, it can be defined as middle speed, high speed and high speed VFD centrifuge. It is mainly use for recycling the barite, removing the fine solid particles sized in 2-7μm, controlling the density and viscosity of drilling fluid to keep the drilling fluid performance. It is widely used in solid control system for drilling mud to separate the solids phase of mud, remove harmful fine drill solids such as debris, etc. in the mud fluid, or recover weighting materials such as barite etc. so as to reduce the cost of mud fluid.Additionally, this high speed centrifuge machine-- Drilling Fluid Decanter Centrifuge offers strong material adaptability, continuous operation, ease of operation, easy installation, low operating costs, and a small footprint, among other significant advantages. It has good separation effect In oil and gas drilling, horizontal directional drilling, micro tunnel, tunnel construction, drilling waste management and wastewater treatment.Working PrincipleThis machine operates based on the settling principle and is designed for the separation of solid and liquid phases in a suspension. The suspension enters the spiral pusher through the feed pipe, accelerates after passing through the accelerator, and then enters the drum. Under the influence of centrifugal force, the solid phase is thrown towards the inner wall of the drum. The spiral blades push the solid phase sediment through the slag discharge outlet. The lighter liquid phase is continuously clarified within the drum and flows towards the large end of the drum, exiting through the overflow outlet.Structural Feature1. Structure Of Drilling Mud Decanter Centrifuge DrumThe Drum Is Divided Into Cylindrical And Conical Sections And Has Components Such As The Large End Shaft, Differential,Connecting Plate, And Auxiliary Motor Belt Pulley On The Left End. The Right End Includes The Small End Shaft, Main Motor Belt Pulley, And Feed Pipe. Rib Strips Are Welded Inside The Drum To Prevent Material Slippage. It Has A Slag Discharge Outlet On The Small Cone End For Solid Phase Material Discharge, And An Overflow Outlet On The Large End Shaft To Control Liquid Clarity.Spiral PusherComprising a cylindrical column section, material accelerator, baffles, spiral blades, and shafts, the spiral pusher's helix is double-ended and left-handed with a hard alloy surface. It connects to the differential and achieves solid-phase material discharge due to speed differences.Transmission MechanismThis includes main and auxiliary motors, hydraulic couplings, belt pulleys, bearings, and a planetary gear differential. The differential is critical and uses a two-stage planetary gear transmission.Protective Measures:  To ensure safety, several protective measures are in place:* Belt pulley-type hydraulic coupling ensures smooth operation and overload protection.* Torque overload protection safeguards against material blockages.* An inverter monitors and shuts down the centrifuge in case of overload4.
