Mud cleaner

Release time: 2015/10 / 08Solid control equipmentViews : 9369

The working principle of the mud cleaner:

The vibrating screen, the sand remover and the desilter are integrated into one. After the drilling fluid mud is processed by the vibrating screen, the solid particles become smaller and the content is reduced, and the drilling mud needs to be further purified. The drilling mud is pumped from the sand silo to the sand removal cyclone through the slurry pump. After the cyclone is separated, most of the solid particles> 47 microns are sprayed out and fall on the underflow sieve. Screened and discharged to the tank, and the mud entering the desilting silo will be transported to the desilting cyclone by the desilter supply pump again. At this time, most of the solid particles> 15 microns will be discharged. The filtration and conveyance of the underflow sieve, most of the solid particles of the slurry falling into the silt silo are less than 15 microns, which makes sufficient preparation for the further processing of the centrifuge.

Application scope of mud cleaner:

Onshore and offshore oil and gas drilling / CBM excavation / non-excavation directional crossing / pile engineering / wastewater, mud treatment and other projects, the second and third stage solid control treatment of mud and liquid to be treated. In short, the mud cleaner is suitable for the treatment of mud and solid-liquid mixtures in various drilling environments.

Influencing factors of mud cleaner:

Drilling depth, drilling fluid performance, comprehensive drilling environment / conditions, selection of screens, selection of slurry pumps, etc.

Structural components of mud drilling fluid cleaner:

It mainly includes base, frame, screen bed, excitation beam, excitation motor, screen box angle adjustment device, screen, sand removal cyclone group, mud removal cyclone group, pressure gauge, corresponding pipeline, etc.

Installation instructions for mud cleaner:

The mud cleaner will be installed after the vibrating screen, because the sand remover and the mud remover are second- and third-level solid control equipment . The slurry processed by the vibrating screen is pumped into the cleaner in the sand silo. The predetermined cleaner position on the tank surface will have positioning blocks to help users confirm the position and distance, and the corresponding tank surface will also be on the tank top. Holes were made to allow the treated clean mud to fall into the tank through a screen. The mud tank should be placed on a flat and clean floor to minimize the impact of the external environment on the performance of the equipment. In the process of transportation or transfer, it is not suitable to install the screen on the screen box to avoid collision and other damage to the screen and affect the use. The transport locking device must always be tightly closed. Before installation and use, remove the transport locking device to ensure the normal operation of the equipment.

Safe operation of mud cleaners:

It must be determined that the transport locking device is removed before use. Do not repair, move, or even disassemble the motor while the equipment is in use. Ensure that the pipeline connection of the desilter and desilter is stable and reliable, and there is no leakage at the inlet and outlet positions. Observe the pressure gauge reading to make sure it is within the safe value range.

Maintenance of mud cleaner:

Pay attention to the maintenance of the cyclone, and clean and maintain the drip nozzle and other components to ensure better use of the product and a longer service life as much as possible;
Regular and reasonable maintenance of the motor should be performed according to the safety warning of the vibration motor, such as filling with lubricant;
In the process of use, it is necessary to make careful observation and inspection of the condition of the screen. Repair or replace broken screens and completely damaged screens in a timely manner;
After each stop of use, the necessary cleaning of the underflow sieve and sieve should be done to make the sieve have a longer life;
Check and maintain the overall condition of the vibrating screen in a regular and planned manner, so as to achieve the best use of the vibrating screen.

Notes on mud cleaners:

The cyclone sometimes has nozzle clogging and does not produce slurry. At this time, the drip nozzle cover should be unscrewed and simply unblocked to restore normal. When the cyclone group, the sprayed liquid is non-uniform umbrella-shaped, please properly turn the drip nozzle and observe its state to restore it. Please refer to the manual for details.
The spraying force of the mud discharged by the cyclone is very small, which may be the pressure or the displacement of the slurry pump is insufficient. Please consider adjusting the bottom flow screen of the pump set during use. There may be a phenomenon of running slurry or blocking. Adjust the screen box angle, but it should not be raised or lowered too much. In addition, observe and monitor in time to ensure that the selected screen is suitable for the mud at a certain stage.
When the underflow screen does not move according to a predetermined trajectory, there may be a problem with the vibration motor circuit. For example, if a single motor is running, or the installation direction is wrong, you should disconnect the source and check the motor or line to restore it
