Mud vibrating screen is a kind of mud processing equipment with a wide range of uses. In the field of petroleum drilling, it is often used as a first-level solids control equipment to process drilling mud, also known as solids control vibrating screen. According to the needs of solids control equipment, the mud vibrating screen can be divided into many types, including: single-layer mud vibrating screen, multi-layer mud vibrating screen, dry mud vibrating screen, variable frequency mud vibrating screen, etc. The solids control vibrating screen used in the oil drilling field, as well as the mine vibrating screen in the mining field, etc. Information about the working principle, use, structure, installation, operation, and maintenance of the shale shaker will be sorted out and shared with you.

The working principle of the mud vibrating screen:

The exciting force generated by the vibrating motor drives the sieve bed to move in a straight line, a circle, an ellipse or a translational ellipse. The screen will play the role of filtering and screening, sieving out solids such as large particles of drill cuttings, and the treated clean mud with fine particles will fall to the vibrating screen bin to wait for the next level of processing. The separated large solid particles (usually above 74 microns) are transported to the outside of the sieve bed under the excitation force and discharged out of the tank.

The scope of application of mud vibrating screen:

Primary or secondary or tertiary solid control treatment for mud and liquid to be treated in land and offshore oil and gas drilling / coalbed methane excavation / non-excavation directional crossing / piling engineering / waste sewage, mud treatment and other projects. In short, it is suitable for the primary treatment of mud and solid-liquid mixtures in various environments.

Factors affecting the performance of mud shaker:

Drilling depth, drilling fluid performance, land environment, comprehensive drilling environment/conditions, selection of screens, comprehensive performance of objects to be processed, etc.

The structural components of the shale shaker:

Mainly include base, frame, screen bed, mud logging tank, excitation beam, excitation motor, control cabinet, screen box angle adjustment device, screen, fixed screen device, etc.

Installation instructions for mud vibrating screen:

Usually the drilling fluid shaker is installed on the first mud tank. There will be a positioning block at the location to help users confirm the location and distance. The top of the tank where the vibrating screen is located will also have an opening the size of the screen bed to receive the cleaned mud. The mud tank should be placed on a flat and clean ground to minimize the impact of the external environment on the performance of the vibrating screen. In the process of transportation or transfer, it is not advisable to install the screen on the screen box to avoid collisions and other damage to the screen, affecting the use. The transportation locking device must always be in a tightly closed state. After installation, the transportation locking device should be removed before use to ensure the normal operation of the vibrating screen. During the installation process, read the installation manual and follow the corresponding constraints to complete the installation.

The safe operation of the shale shaker:

It must be ensured that the transport locking device is removed before use. The equipment cannot be repaired, moved, or even disassembled during the use of the vibrating screen. Operate and maintain the equipment in accordance with the safe operation instructions and warning signs given on the equipment.

Maintenance of mud vibrating screen:

1. The motor should be maintained regularly and reasonably according to the safety warnings of the vibration motor, such as adding lubricating oil, etc.;

2. In the process of using, carefully observe and inspect the condition of the screen. The damaged screen and the completely damaged screen should be repaired or replaced in time;

3. After each stop of use, the vibrating screen and the screen should be cleaned as necessary to make the screen have a longer life;

4. Inspect and maintain the overall condition of the vibrating screen in a regular and planned manner, so as to achieve the best use effect of the vibrating screen.

5. Precautions for using the drilling fluid vibrating screen: During the use of the vibrating screen, slurry running or screen blocking may occur. At this time, we need to adjust the angle of the screen box, but it should not be excessively raised or lowered.

6. Timely observe and monitor to ensure that the selected screen is suitable for a certain stage of mud. When the vibrating screen does not follow the predetermined trajectory, it may be a problem with the vibrating motor circuit. For example, a single motor is running or the installation direction is wrong. At this time, disconnect the source and check the motor or circuit to restore it to normal.
