Product Introduction
The vacuum vibration screen, also known as the negative-pressure vibration screen, is a screening device that uses vibration combined with vacuum suction to separate solids from liquids in drilling cuttings. By leveraging both vibration and negative-pressure suction, the discharged drill cuttings become drier, thereby reducing drilling costs. Vacuum (negative-pressure) vibration screens are widely used for recovering drilling fluids, minimizing drilling waste, and enhancing the overall efficiency of vibration screening operations.
The working principle of the vacuum vibration screen involves installing a negative-pressure adsorption system beneath the screen's final mesh. This system uses pulsed airflow to generate vacuum suction at a specific frequency, enhancing the recovery of drilling fluid while significantly reducing the liquid content in the discharged drill cuttings.
Alternatively, an additional small sieve with negative-pressure adsorption can be externally mounted at the discharge port of the customer’s existing vibrating screen, enabling vacuum adsorption and recovery of drilling fluid before drill cuttings are discharged.
Product Advantages
1. It can be used for treating muds based on oil (BOM), water (WBM), and synthetic (SBM) bases.
2. It can be applied to both land-based and offshore drilling rigs, enhancing the efficiency of solids control equipment—specifically, vibration screens—while recovering drilling fluids and reducing waste volume.
3. It can replace the treatment provided by drill cuttings dryers, yet at a lower cost.
4. Requires almost no additional land area, perfectly meeting the space requirements of offshore platforms.
6. The solids-control vibrating screen can accommodate higher-mesh screens without losing slurry, thereby enhancing the separation efficiency of the solids-control equipment.
7. By emitting drier drill cuttings, it is possible to reduce the costs associated with transporting and handling drilling waste.
8. Installation and operation are simple—only one operator is needed to manage the vacuum vibrating screen for the entire drilling rig.
