Mud cleaner with rectangular recycle vibrating screen

We know, drilling mud cleaner has been an 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.

It is combined plus arranged by one to 3 hugely wear-resisting polyurethane hydrocyclone 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.

Mud agitator can generate vortex motion

Mud agitator can generate vortex motion, thus increasing the stirring effect. Clamp the blade in the middle of the tray can be prevented after the shutdown slurry of solid particles deposited on the periphery of the lower blade, so that when starting to use the precipitate can reduce the resistance moment of the blade, thus avoiding the motor starter overload and burn.
It is an important part of the mud solids control system. It is mounted on the circulating tank. The vanes of the agitator dip into the mud to agitate the fluid uniformly.

A Mud Agitator is used in surface of mud system to suspend solids and maintain homogeneous mixture throughout the system. A mechanical agitator is driven by an explosion-proof motor, coupled to a gear box that drives the impeller shaft. The impellers (turbines) transform mechanical power into fluid circulation or agitation. The objective is to obtain a uniform suspension of all solids.

Mud Agitator

The Structure of mud agitator

The main parts of mud agitator including explosion–proof motor, reducer, shaft, impeller, shaft adapters are used in connections of reducer to motor, and reducer to impeller wheel.

The motor of mud agitator

All motors used in KOSUN mud agitator are ISO brand and explosion motor in China, any other requirements required by clients, we can choose different brand for customs. the size range from 5 to 30 kw.

The impeller and shaft of mud agitator

The mild steel shaft is coupled to the gear reduction assembly with a rigid coupling. All shafts are keyed at the bottom for adjusting the height of the impeller. Shaft length is depend on the depth and should be informed before ordering.
The canted blade impeller used in tanks deeper than five feet, promotes axial as well as radial flow. Because the blades move the liquid downward to the bottom of the tank and then toward the tank walls and up, all fluid is mixed continuously and the same consistency is maintained in all parts of the tank. Field experience has confirmed that this design provides the most homogeneous mixture over the widest range of installations and helps to eliminate heavy slugs or light spots that could cause control problems when pumped down-hole. The impeller developed by KOSUN are classified single and double impellers which depend on the tank size and custon requirements.
