15KW Drilling Waste Management Equipment Screw Conveyor For Oilfield System

Drillling Waste Management Equipment 15KW Screw Conveyor Used In Oilfield Drilling System

Description of screw conveyor

Screw conveyor is designed to deliver drilling cuttings and feed to vertical cuttings dryer or High G dryer for further treatment. It is also called auger feeder. Usually, the screw diameter has 4 options: 10 inch, 12inch, 16 inch, 20 inch; screw length is customer built too, but commonly there are 12~48feet. Furthermore, depends on clients’demand the screw conveyor will be made of different materials. Including carbon steel, stainless steel graded differently.

Screw conveyor is also referred to Auger feeder. They can be used as the transfer unit of drilling cuttings to cuttings dryer, also the unit to transfer disposal to cuttings tank or collection container. The length can be custom built according to actual working condition.

Screw conveyor features

WLS shaftless screw conveyor is one of the commonly used continuous conveying equipment. Due to its simple structure and small cross-sectional area, especially its ability to be transported in a closed manner, it has the advantages of low environmental pollution and is now being used by industries such as sewage treatment, environmental protection, and drilling. One of the preferred equipment for material conveying. Choose international standard products. The design and manufacture conform to professional standards, the technical indicators are advanced, the overall shaftless structure is adopted, and the position of the inlet and outlet is flexible.

Working principle and application

The material conveying of the shaftless screw conveyor is driven by the rotating blades, and the conveying direction determines the left and right rotation and rotation direction of the screw blades, so it can be conveyed in one direction and two directions according to the needs, and can also be multi-pointed. It can be installed horizontally or inclined at a certain angle. The material enters the screw body from the feed port
www.aipusolidcontrol.com and the material is transported out from the discharge port through the rotation of the screw. The length of the conveyor is selected by the customer, and the power drive unit can be combined in various ways. It can be installed at the inlet end or the outlet end of the conveyor. The bottom of the U-shaped groove of the equipment is provided with an anti-wear protective bushing. He chooses according to the different materials to be conveyed. It is selected according to the different materials to be conveyed. Application: WLS series shaftless screw conveyors are used in sewage treatment plants to transport medium and fine grid decontamination machine screen slag and filter press mud cake, as well as domestic waste, sludge, mud and other entangled materials. Good environmental performance. The use of fully enclosed conveying and easy-to-clean spiral surfaces can ensure environmental sanitation and the stacked materials will not be polluted or leaked. High torque and low energy consumption. Since the screw has no shaft, the material is not easy to be blocked, and the discharge port is not blocked, so it can run at a lower speed, drive smoothly, and reduce energy consumption. The torque can reach 4000N/m. Large delivery volume. Long conveying distance. A single machine can be up to 30 meters long. According to user needs, it can be installed in multi-stage series to transport materials over long .

Installation and commissioning

The correctness of installation is one of the necessary conditions for good use in the future. The on-site installation should be carried out reasonably and meet the following conditions.

1.The installation of the auger should meet the installation foundation, can reliably support the conveyor, and ensure that the screw machine does not sink and additional changes due to the small place, and ensure that the screw machine has sufficient stability during operation.

2. Before installation, the screw conveyor must be cleaned by the grime stuck on the unloaded box during transportation.

3.The flanges of adjacent casings should be connected smoothly and tightly, and the deviation of the dislocation distance at the joints on the inner surface of the casing should not exceed 2 mm.

4. The housing flanges allow for padded asbestos strips to adjust the accumulation of housing and spiral length.

5. The gap between the outer diameter of the auger and the casing should meet the requirements in the table, and the minimum gap should not be less than 60% of the value specified in the table.

6. Each intermediate suspension bearing of the auger should be reliably fixed on the lifting lug of the casing, the screw rotates evenly, and must not be stuck. During installation, spacers can be added between the suspension bearing base and the casing lifting lug to ensure that each suspension bearing Coaxial, after installation, the interaxiality of the spiral body axis should meet the requirements.

7. The coaxiality of the main shaft of the auger and the shaft of the geared motor shall comply with GB1184-80 "Shape and Position Tolerance, No Tolerance Regulations"

8. After the base of the auger is installed, the anchor bolts are tightened.

9.All coupling floor nails shall be tightened to a reliable degree

10.Inlet and outlet site installation should make the inlet and outlet flange support surface parallel to the axis of the screw machine body, and the connected flange should be closely fitted, no gap.

11.After the auger is installed, check whether there is enough lubricating oil in each oil storage place. If it is not enough, add enough, and then the no-load test can be carried out. After the no-load test run for more than 4 consecutive hours, the screw machine assembly should be checked. If it is found that it does not meet the following conditions, it should be shut down immediately, and then run after correction until it is in good operating condition. When powering on the test auger, it should be jogged first to confirm that there is no friction between the parts, and then the normal test operation can be started. Start the test run for two hours to run in the newly assembled parts. Some appropriate lubrication (such as soap solution) should be used to reduce vibration and noise. If there is no lubricating facility, turn the screw with empty car, otherwise the bushing will be seriously damaged.
