The screw conveyor produced by xi ‘an KOSUN is used in the drilling waste disposal project, providing an effective and low-cost drillings transportation system for offshore drilling and land drilling devices. The screw conveyor adopts the combined structure of more than 12 feet in each section, which can be flexibly assembled and used in different drilling sites, with simple operation, stable structure, strong adaptability in working space and high safety performance. Thus, the working efficiency of the equipment is greatly improved and the cost and resources are saved. The screw blade of screw conveyor is made of wear-resistant material to ensure its service life.
When the screw shaft rotates, the material can only move forward along the bottom of the screw conveyor under the push of the blade due to the gravity of the material and the friction generated by the friction between the material and the tank wall, which is just like the translation movement of the unrotatable nut along the rotating screw. The movement of the material in the intermediate bearing depends on the thrust of the material moving forward behind it. Therefore, the material transport in the conveyor, is a complete slip motion. In order to make the spiral shaft in a more favorable tension state, generally will drive the device and discharge port on the same end of the conveyor, and the feed port as far as possible on the other end of the tail near. The rotating spiral blade moves the material and carries on the transportation, causes the material not to revolve together with the spiral conveyor blade the force is the material own weight and the screw conveyor casing to the material the friction resistance. According to the different materials, there are solid surface, belt surface and blade surface. The spiral shaft of the screw conveyor has a thrust bearing at the end of the direction of material movement. Intermediate hanging bearings should be added when the captain is longer.
