Drill cutting dryer is also called rock cutting dryer, drill cutting dryer and rock cutting dryer, which is the main equipment in the mud non-falling processing (waste slurry treatment) system.
Working principle of drill cutting dryer:
The material enters the space between the sieve basket of the drill cutting dryer and the spiral scraper through the feeding cone through the feeding cone. Under the action of centrifugal force, water and small particles (centrifugal liquid) pass through the material layer, pass through the screen, flow into the water collecting tank of the upper casing along the upper cover, and then are discharged through the drainage pipes provided on both sides of the cuttings dryer. Outside the machine; the particles are kept inside the screen. Due to the speed difference between the spiral blade and the screen basket, the spiral blade scrapes the particles from the screen and discharges them to the bottom of the screen, thereby dewatering the material. Unload into the receiving funnel below the machine. This dehydration process is performed continuously.
Scope of application of cuttings dryer:
Onshore and offshore oil and gas drilling / CBM excavation / non-excavation directional crossing / pile engineering / wastewater, mud treatment and other projects.
Influencing factors of cuttings dryer:
Drilling depth, drilling fluid performance, land environment, comprehensive drilling environment / conditions, comprehensive performance of objects to be treated, etc. and environmental protection requirements to be met.
Structural parts of drill cutting dryer:
The working part is mainly composed of a screen basket, a spiral discharge rotor, a bell-shaped hood and a cloth cone, etc., as well as a transmission part and a lubrication system.
Installation instructions for drill cutting dryer:
1) Before installation: Check whether the foot size of the installation site is consistent with the drawings, and also check whether the installation site is level with a level gauge. The horizontal error of the lower positioning surface of each shock absorber of the drill cutting dryer does not exceed 2 ‰. Board adjustment.
2) Installation: The cuttings (drilling cuttings) dryer should be installed as integrally as possible, and the lifting position should be selected at the appropriate position of the machine base and the motor base. Do not use the two lifting ears on the upper cover to lift the whole machine. If the situation does not allow disassembly and installation, the components should be removed from the base in the following order: V-belt, (relevant) lubrication pipeline, fuel tank, motor and bracket, etc .; when installing, first install the main part, and then Install the removed parts in the reverse order of disassembly.
