Aipu Waste Management 528GPM Drilling Shale Shaker

Aipu Drying Shaker Used In Waste Management Or Drilling Fluids Process

The main function of drying shaker

The dryer shaker, or dryer, is a linear motion shaker used to minimize the volume of liquid associated with drilled cuttings discharged from the main rig shakers and hydrocyclones. The liquid removed by the dryers is returned to the active system.

The dryer shaker deliquifies drilled cuttings initially separated by another piece of solids-separation equipment. These drilled solids can be discharged from the main shaker or a bank of hydrocyclones. Dryers recover liquid discharged with solids in normal liquid/solids separation that would have been previously discarded from the mud system. This liquid contains colloidal solids, and the effect on drilling-fluid properties must be considered since dewatering systems are frequently needed to flocculate, coagulate, and remove these solids.
The dryer family incorporates pieces of equipment long used as independent units: the main linear motion shaker, the desander, and the desilter, which are combined in several configurations to discharge their discard across the fine screens (e.g., API 200) of a linear motion shaker to capture the associated liquid. These units, formerly used as mud cleaners, are mounted on the mud tanks, usually in line with the main linear motion shaker. They can be tied into the flowline to assist with fine screening when not being used as dryers. Their pumps take suction from the same compartments as desanders and desilters and discharge their overflow (effluent) into the proper downstream compartments.

AIPU Hunter Drying Shakers are an ideal and effective solid control equipment for high-capacity treating in the heavy loading and tough drilling conditions , its easy to maintain, the single side screens tension system make it easy to change the screens. The AWD system could change the angle of shaker deack from -1°~5°,it can remove cuttings above 75μm brought from the drilling.

Hunter drying shaker is the first generation of high-frequency shale shakers according to the international standard which has special structure and stable processing results and gains more praise worldwide.

Hunter drying shaker is designed in linear motion and high vibration mode to achieve the expected separation effect.

How to use it

A linear motion dryer may be used to remove the excess liquid from the main shaker discharge. The flow rate across a linear motion dryer is substantially smaller than the flow rate across the main shaker. The lower flow rate permits the removal of the excess fluid by the linear motion dryer by using a finer screen. The dryer is usually mounted at a lower level than the other solids-separation equipment to use gravity to transport solids to it. Whether by slide or by conveyor, the cuttings dump into a large hopper, located above the screen, that replaces the back tank, or possum belly. As the cuttings convey along with the screen, they are again liquefied. This excess fluid, with the fine solids that passed through the screens, is collected in a shallow tank that takes the place of a normal sump. The liquid is pumped to a catch tank that acts as the feed for a centrifuge or back to the active system.

Why use dryer shaker

Dryers were introduced with the closed-loop mud systems and environmental efforts to reduce liquid-waste haul-off. Two methods, chemical and mechanical, are available to minimize liquid discharge. The chemical method uses a system called a dewatering unit, while the mechanical method takes place through linear motion shakers. These systems may be used separately or together.

Benefits of dryer shaker

Drying shaker, the first choice of oilfield environmental waste drilling cuttings screening and drying, combined with USA advanced technology, winning the order quantity of 50 sets in the USA and 2 sets for export to Russia, is the product which is firstly guided by the domestic and gains high customer recognition and bulk subscription.

1. High efficiency and varied frequency.
2. The capacity is 30% higher than that of the same product on equal conditions.
3. Less vulnerable spare parts, easy operation, and maintenance.
