Abstract

A petroleum drilling rock cutting swing dryer belongs to the technical field of solid-liquid separation equipment and aims at solving the problems that the existing solid-liquid separation equipment is unreasonable in construction design and can cause environment pollution and resource waste. A conical screen is fixed on a rotation arm, a central shaft is installed in a shaft hole of a rotation arm, a scrapping device is installed on the central shaft, a gearbox is fixed on an outer shell of the swing dryer, a motor is connected with an input shaft of the gearbox, the gearbox is connected with the rotation arm and the central shaft, partitions are installed inside an outer shell of a base of the swing dryer and separate the shell into a wet cavity, a dry cavity and a transmission cavity, a feeding funnel is fixed at the top of the outer shell of the swing dryer, and a discharging funnel is fixed at the bottom of the outer shell of the swing dryer. The petroleum drilling rock cutting swing dryer is simple in structure and applicable to solid-liquid separation and recycling of petroleum drilling rock cuttings and solid-liquid separations of other fields.

Description

Oil drilling landwaste drier

Technical field

The utility model belongs to a kind of discarded object that produces in the Process of Oil Well Drilling-contain solid-liquid separating equipment of liquid well drilling detritus that recycles in the solid-liquid separating equipment technology neck.

Background technology

Along with growing and scientific and technical the advancing by leaps and bounds of oil drilling industry, also increasingly high to the specification requirement that recycles the discarded object solid-liquid separation equipment that produces in the Process of Oil Well Drilling.In known technology, the solid-liquid separating equipment that uses in the oil drilling at present mainly contains vibratory sieve, desander, desilter, centrifuge etc.But the main effect of existing equipment is the landwaste withdrawal liquid of removing in the drilling fluid, also contains the liquid about 20% in the landwaste of separating, and these liquid have caused the waste of environmental pollution and drilling fluid resource again with the landwaste discharging.

Summary of the invention

In order to overcome the deficiency of prior art, it is unreasonable to solve the design of existing solid-liquid separating equipment structure, contaminated environment and waste problem of resource.The purpose of the utility model provides a kind of simple and practical, and the content liquid in the well drilling detritus is reduced to below 5%, to reduce the new-type solid-liquid separating equipment of environmental pollution and drilling fluid waste widely.

The utility model solves the above-mentioned technical scheme that adopts:

A kind of oil drilling landwaste drier, it is provided with: taper screen cloth, charging hopper, material scraper pressing plate, material scraper, drier shell, central shaft, pivoted arm, speed changer, motor, first belt pulley, dividing plate, second belt pulley, discharge funnel, storage tank, base, dividing plate, bearing, discharging tube, conical screen cloth are fixed on the pivoted arm that rotates together with one of which; The axle of pivoted arm is in its axis hole of hollow shaft central shaft to be housed, and central shaft is equipped with material scraper through the bearing supporting on the central shaft; Be shaped on several material scraping plates on the material scraper; Pivoted arm is connected driving with central shaft by speed changer, and speed changer is fixed on the drier shell, and motor drives second belt pulley by first belt pulley; Second belt pulley connects the power shaft of speed changer; The transmission mechanism of speed changer connects homodromal pivoted arm and central shaft, and the drier support is made up of base, storage tank and drier shell, is connected with dividing plate in the drier shell casing is divided into wet chamber, dried chamber and drive cavity totally 3 chambers; Discharging tube is housed on the wet chamber and connects wet chamber and storage tank; Have dividing plate to do in the dried chamber and be separated out drive cavity in the chamber, the top of drier shell is fixed with charging hopper, and the bottom is fixed with the discharge funnel.

When the utility model uses, this drier is attached to desired location, good in succession power supply is added oil drilling landwaste to be separated by charging hopper, and starter motor just can carry out the Separation of Solid and Liquid operation.The well drilling detritus that contains liquid gets into the well drilling detritus drier from funnel, at first fall on the material scraper pressing plate of rotation, is thrown to the inwall of taper screen cloth then; Together rotate with the taper screen cloth, under the double action of material scraper and gravity, fall gradually simultaneously, under action of centrifugal force; Liquid throws away through the slit of taper screen cloth, gets into wet chamber, and enters in the storage tank through discharging tube and to reclaim; Solid can be scraped by material scraper; Fall the bottom of taper screen cloth and be thrown out of, get into and do the chamber, the hole of passing on the pivoted arm falls into the funnel discharging.

Because technique scheme has been adopted in the utility model design, it is unreasonable to have solved the design of existing solid-liquid separating equipment structure effectively, contaminated environment and waste problem of resource.Also testing result on trial for several times through North China Oilfield, accurate eastern oil field etc. shows; It compared with prior art; Have simple and practically, the content liquid in the well drilling detritus is reduced to below 5%, reduce beneficial effects such as environmental pollution and drilling fluid waste widely; Be applicable to the Separation of Solid and Liquid and the recovery of oil drilling landwaste, and the Separation of Solid and Liquid of other suitable industry.
