Drilling fluid mud cleaner is the second stage separation equipment

The mud cleaner is the two-level together with three-level solid manage equipment for the drilling mud. It combines the hydrocyclone desander, the hydrocyclone desilter at the same time as the underset vibrating screen together. The mud cleaner would be the ideal and then efficient cleaning gear for two-level three-level solid phase control associated with the drilling mud because of its compact structure, tiny space occupation coupled with potent functions. The mud cleaner is combined plus arranged by one to 3 hugely wear-resisting polyurethane hydrocyclone mud desanders too as eight to sixteen very wear-resistant polyurethane hydrocyclones. Diameters for its overflow pipe feed pipe are bigger while taper angles associated with the cone are smaller sized. A tilted metallic groove fixed with the center shaft is used inside the mortar steering component to manage flow direction about the mortar. The cyclone group arranged in circle is employed together with the rectangular recycle vibrating screen. The function connected with the mud cleaner is to cope with larger drilling cuttings in the mud in order to ensure the remedy impact too as service life related with those latter strong handle systems. What’s more, the mud cleaner has such positive factors as lower energy consumption, higher efficiency, larger screening precision, less noise, straightforward and handy installment, basic maintenance, shear pump,longer service life, larger efficiency in drilling solids separation, basic structures, reduced costs and additionally convenience in movement and additionally relocation.

Drilling fluid mud cleaner is the second stage separation equipment of mud system
Drilling fluid mud cleaner is the second or third stage separation equipment of drilling liquid, which deals with the mud after being treated by the first grade separation equipment. The Driling fluid Mud Cleaner barite will be recovered and cuttings which are bigger than barite will be removed. Then the drilling fluid mud cleaner barite in the underflow will flow into circulation tanks through the screens when the weighted mud passes while the particles that are bigger than mesh will be removed.It occupys small space and the function is powerful , mud cleaner is the ideal device of the second class and the third class solid control to treat the drilling mud.

Causes and Solutions of Sand Fill in Hydrocyclones

Hydrocyclones are major components in desander, desilter and mud cleaner and assist most of their works. A hydrocyclone has a upper casing, a lower casing, a underflow mouth as well as auxiliary parts. The upper casing is an inlet chamber in cylindric with an inlet pipe on one side and a vortex tube in top middle as the overflow. The lower casing is a cone whose angle ranges from 15°~20° at the tip. The underflow mouth is located at the bottom as the discharge port for solids.

The work principle of hydrocyclones is to separate two or several components with different densities with the aid of centrifugal force. After the mixture is sent into hydrocyclones by certain pressure, it gradually flow into a high-speed rotation where the heavy phase form an outer swirl by moving downwards along the axis, outwards along radial direction, downwards again along the cone till they flow out of underflow; while the light phase form upward inner swirl by moving towards axis and upwards till they go out from overflow outlet. Thus, the separation is done.

Sand fill is the commonest anormaly to hydrocyclone and is categorized as:

Sand fill at the underflow: it happens as a consequence of improper adjustment that results in  dry bottom or of excessive silt content which brings about overloaded hydrocyclone. It should be removed immediately as it affects the purification ability and accelerates abrasion of lining and vortex tube. Usually the best ways are to enlarge underflow outlet or to have more solids taken away by preceding equipment. 

Sand fill at the inlet: it can be partial or overall. Partial sand fill decelerates fluid flow inside inlet, leaks enormous drilling fluids from underflow and sometimes clean mud which may flow backwards from the overflow as, at that time, hydrocyclone is not more functional than a hopper. Overall sand fill is prone to back flow drilling mud from the overflow. Inlet sand fill generally stems from poor drilling fluids management, and most likely from going round the shale shaker or abrading shaker screens.

Jet mud mixer for solids control drilling mud system

A good mud mixing and additive system should be a jet-shear mud mixing system, which commonly has three functions: shearing, jet mixing and drilling fluids additive. KOSUN designs and produces such multifunctional equipment.

 Jet mud mixer for solids control system

Jet mud mixer can be mounted on a separate skid then connected with a mud mixing tank, or they can be mounted on the skid of the tank. The latter way is a compact structure of mud mixing unit, and the former way can be more flexible to move the mud mixing unit from one place to another. But you do not have to move it all the time, the mud mixing pipelines which is controlled by butterfly valves can reach this target, too. Install hopper with a mixing pump is the simplest way for the mud mixing unit. Centrifugal pump can be replaced by shear pump or called it jet mud mixer. Jet mud mixer is designed to use shear pump to efficiently mix solids with liquids. Jet mud mixer ensures efficient mix of soluble polymers and bentonite used in water-based drilling fluids, therefore eliminating “fish eyes”. Drilling fluid yield and gel strength properties are instantly obtained with hydraulic shearing of bentonite or organophilic clays.

Established in 1992 KOSUN is the first group of manufacturers of drilling fluids solids control equipment,and an expert in drilling waste treatment.It is the forerunner of solids control equipment in China, which is specialized indecanter centrifuge,shale shaker,desander,desilter,mud cleaner and complete solids control system.. As the professional advanced decanter centrifuge supplier,KOSUN has won high recognition and praise from domestic and abroad with science core technique and a lot of innovative patents.At present, KOSUN’s business scope mainly covers China mainland, Commonwealth of Independent States, North Africa,Australia, U.S.A.and etc.

Linear Motion Mud Cleaner Working Principle

In the dual simultaneous flow mode the top deck handles the mud cleaner underflow and the bottom deck handles the primary scalping. The mud cleaner is a six panel dual deck multifunctional drying shaker with desander and desilter. It has two 2.4 HP (1.8 KW) vibratory motors and a maximum shale shaker screen surface area of 56 sq. ft. (5.2 sq. m) capable of handling 500 to 1,500 gpm (31.5 to 94.6 lps).

All units can be provided with 380V / 50Hz or 460V / 60Hz; generate a noise level less than 80 decibels (dB); and are fitted with an adjustable deck capable of inclinations of -2 to +5 degrees. When drilling top-hole sections, where heavy, high volume solids are typically encountered, the high G-Force design will effectively move the solids across the shale shaker screens. All units come standard with explosion proof motors and enclosures.
