Standard Professional Mud Recycling System Supplier

DC Mud Recycling System is the economic way for the mud recycling, it is popular for HDD and Bored Pile Slurry desanding plant, TBM slurry treatment, HDD (trenchless) as well as water well drilling etc.

mud cleaning system

Usually bored pile is used for those tall buildings or massive industrial complexes, which require foundations that can bear the load of thousands of tons, most probably in unstable or difficult soil conditions. In order to ensure Bored Pile can works properly. DC Machienry design many sets mud removal system for different
conditions:
DC Mini solid remove system Models:
DCS-200D Capacity: 200GPM,50m3/h
DCS-500D Capacity: 500GPM,120m3/h
DCS-1000D Capacity: 1000GPM,240m3/h
Other models should be customized.

DC Machinery also customized different industries mud circulationg system based on your requirement. We have professional equipment used in the system, such as shale shaker, desander, desilter, mud centrifuges, mud tank, agitators and ect. Please contact us if you want to get more infos.

Welcome your inquiry DC Decanter centrifuges

Sludge dewatering is the separation of a liquid and solid phase whereby, generally, the least possible residual moisture is required in the solid phase and the lowest possible solid particle residues are required in the separated liquid phase (“the centrate”).

DC Machinery can provide the most professional decanter centrifuge used for slurry treatment. The centrifuge consists of a solid bowl, which rotates and contains the process. A screw conveyor, contained within the bowl, turns at a slightly different speed from the bowl.

DC Machinery Decanter Centrifuge units are supplied with advanced controls for both variable speed bowl and scroll back-drive optimization making them easily configured to produce a wide range of sludge dewatering results. The DC Machinwey is very easy to set up while being extremely robust, stable, and reliable in everyday use, without the ease of use detracting from the quality of the operating results.

Besides Above, DC Decanter Centrifuge is designed for the drilling mud solids control and oilfield waste management. DC VFD drive decanter centrifuge with variable speed allows drilling contracor or mud service company to do the barite recovery, fine/ ultra fine solids separation,dewatering centrifuge. DC have the decanter
centrifuge from 9 inch bowl to 22 inch bowl available for different applications. DC decanter centrifuge bowl length and diameter ration is over 3, this gives the best result for the drilling fluids cleaning.

Detailed introduction of the drilling mud storge tank

Mud tank is petroleum drilling fluid solid control system, it is mainly including FG and ZG petroleum drilling mud tank, mud tank circulating system according bottom tank shape is divided into square tank and tapered tank. The tank use flat taper structure or corrugated structure, the steel plate and structural steel installed and welded.

Tank surface and corridor use the anti-skidding steel and anti-skidding bar halftone, tank surface railing use square steel tube manufacture, it is the barrier free and folding structure, the connection is fastness. Mud tank circulating system tank surface matched rinsing pipeline to clean tank surface and equipment, the tank surface halftone use soak zinc processing. The upper tank ladder use U-steel as the main body, using anti-skidding halftone as the footstep, the bilateral guardrail set insurance hooks. Petroleum drilling mud tank has standard sand prevention, prevent canopy, the tank set central heating pipeline.

mud tank

As the mud carrier, mud tank is the indispensable part in mud circulating system, it can complete mud aggravation, mixing, solid liquid separation and degassing process; mud tank transport the mud from well mouth to mud pump, according the relevant solid control equipment, the solid phase particles are separated step-by-step and aggravate accord mud, make it get the drilling technological requirements; The degassing equipment in mud tank can eliminate the harmful gas to ensure the environmental requirements of working condition and specific gravity of slip; mud tank use electric concentrate control. In polar region low temperature district, the tank matched heating supply system and heat insulation system.

Mud tank is designed for at home and abroad landscape, rivers, highway and traversing project. According the recovery and treatment of drilling fluid mud tank can purify drilling fluid, improve horizontal through speed, decrease the wear of mud pump, drill pipe and drill bit, waste mud material, decrease drilling cost, protection environment, mud tank take the considerable economic benefit for users.

Mud tank is a kind of drilling fluid purification device and container. Mud tank is mainly made of tank body, and agitator. The clapboard is separated two parts, the characteristics are; there are two sets centrifugal pump and desander, desilter on the tank top, they are respectively installed on the support which can glide, on the under of desander and desilter respectively installed small shale shaker. The new structure is compact, cover area is small, degassing effect is good, can decrease mud loss. Mud tank apply to petroleum drilling purify treatment and store mud.

500GPM Mud Recycling System For HDD Site

500GPM mud system is a top configuration for HDD site. It contains first phase treatment shale shaker, second phase desander cone and third phase desilter cone installed on shaker for second equipment, 2 sets of centrifugal pumps, 1 set mixing hopper and 1 set of mud tank. The tank size can be customized from 6 meters to 12 meters depending on tank capacity requirement.

Recently, we have one sets of 500gpm HDD mud system ready for delivery.

The HDD compact mud system including equipment as below:

1)1 X Mud cleaner DCQG850, with 6 pcs desilter cyclones and 1 pcs down deck shaker. This mud cleaner can separate the mud solids above 40 microns with desander parts and above 25 microns with desilter parts. 1 microns = 1 X 10-6 meter
2)2 X Centrifugal pump, one is feeding for desilter cones. And the other one is for mixing.
3)1 X mud tank with 3 compartments, storage the mud processed in different steps.
4)1 X electrical control panel which recessed into mud tank for better protection during transporation.
5)1 X accessories, including walkways, ladders, lights, cables etc.

HDD mud recycling system is suitable for construction projects with high mud capacity. Above all, DC Solids Control is a professional manufacturer of HDD mud system in China. Furthermore, we also customize according to client’s requirement. While you have any new inquiry about solids control equipment like shale shaker, mud agitator, mud cleaner, jet mud mixer, vacuum degasser, mud gas separator, flare ignition device, also some mud recovery system, welcome to contact with us. DC waiting for your contact.

How to produce the drilling fluid shale shaker more durable

In order to prevent the innerstress is appeared from welding don’t allow weld screen box and any auxiliary parts.

We should adopt these steps when weld shale shaker:
1. Drilling 6mm hole in one end of flaw in order to prevent flaw extend.
2. Using round shovel spade groove along two sides of flaw.
3. Firstly preheat about 60℃ using 3mm diameter welding electrode to prevent any slag inclusions and bite meat condition.
4. Rubdown the protuberant electrode and weld the stiffening plate.
5. If id needs weld in screen surface bracket beam, all welding line should be parallel with beam.
6. When use alternating current weld the screen box should connect the ground to prevent current conveyance the bearing. 7.
Otherwise it is easy to led bearing damage.
8. The cutting surface will produce stress when flame cut, so the any addition holes all advised drill.

Installation requirements of mud shale shaker

When knit drilling fluid shaker screen and screen bracket is matched special vibration attenuation rubber strip. In order to make screen can reach the longest service life, the rubber strip should placed in among of screen and bracket. We should ensure the equal interval between two sides of shale shaker screen box and screen hook when replace knit screen, we
should fix the centre and compact steel flat at first, then tension the plate to keep the stress of screen surface is uniformity. It is one of the premature failure reason If the connecting is not good, the stress is not enough or uneven.
