Abstract

The utility model relates to a scraping and cleaning device for dirt on the outer wall of a cylindrical body, which is used for scraping and cleaning the dirt on the outer wall of a rod (pipe) during workover treatment on an oil pumping well. The device is composed of a dirt scraping ring and a blowout preventing case, and is installed on the mouth of an oil pumping well. The blowout preventing case is provided with a dirt outlet pipeline so as to prevent dirt from flowing onto the ground to pollute the environment. The work of scraping and cleaning the dirt on the rod is completed during hoisting the rod at the mouth of the well. The entire dirt scraping work does not take much time and exertion, so the labor intensity is greatly reduced, the efficiency of workover treatment is greatly improved, and the expense of cleaning the rod is saved without environment pollution. The device is a preferable dirt scraping device in workover treatment.

Description

Cylinder outer wall dirt is scraped cleaning device

Cylinder outer wall dirt is scraped cleaning device (hereinafter to be referred as scraping cleaning device), be a kind of when on the oil pumpingh well, carrying out workover treatment in order to scrape the crude oil washed on sucker rod or the oil-pipe external wall or the isolated plant of wax deposition (general designation dirt).

Dirt on cleaning rod (pipe) the part outer wall is a tired heavy manual labor.At present domestic when carrying out this operation, be that barre (pipe) part is put on the ground of spreading Polypropylence Sheet after well head proposes, with the vehicle-mounted workshop of arriving, clean then with manually carrying out heating power.This operating type is not only time-consuming but also require great effort, but also has seriously polluted ground environment.

In view of the problem that exists in the above-mentioned operation, the purpose of this utility model is: design a kind of on pumpingh well in well workover lifting arm (pipe) part, just can in well head, the dirt on bar (pipe) the part outer wall be scraped wash clean, accomplish scrape the work of washing time saving and energy saving, not only saved expense, but also " cylinder outer wall dirt is scraped cleaning device " of not polluting ground environment of cleaning rod (pipe) part.

Basic structure of the present utility model is shown in Figure of description:

Among the figure: 3 ball valves, 4 adapters, 5 handles 6 cappings, 7 hoisting nut 8 are scraped washes rod member 9 dirt-scrapping rings 10 dividing plates 11 outer rings 12 bases, 13 threaded joints, 14 well heads, 15 rod member joints

From Figure of description as can be known, the technical solution of the utility model is design like this: scrape the round that the cleaning device profile is similar gyro, be made up of dirt-scrapping ring and blowout prevention box two parts, dirt-scrapping ring (9) is the core of this device, and its floating ground is installed in the blowout prevention box; The blowout prevention box of being made up of capping (6), outer ring (11) and base (12) etc. is the round of a sealing, and two sides respectively are furnished with dirt and dredge out pipeline adapter (4) and ball valve (3).

For implementing the technical solution of the utility model, taked following technical measures in design:

At first dirt-scrapping ring (9) is designed to the cake body, is sleeved on to be scraped on the external diameter of washing rod member (8), when rod member up promotes, with the inner hole wall of its deflation the dirt on the rod member outer wall is scraped and to be washed.Dirt-scrapping ring is to make with the high resiliency nonmetals, also can squeeze to expand to the bigger rod member joint (15) of diameter and pass through, and reaches full bar and scrapes the effect of washing continuously.By capping (6) supporting, held by dividing plate (10) during tenesmus when dirt-scrapping ring rises, be installed in to full floating in the blowout prevention basin, swing and trace in the time of can adapting to rod member and promote rotate operating mode, and the uniformity of washing quality and the not eccentric wear of the endoporus of dirt-scrapping ring own are scraped in assurance.The blowout prevention box be collection dirty, dredge dirty and prevent that blowout effect, two sides be furnished with dirt and dredge out pipeline and take over (4) and ball valve (3), be convenient to collect dirty control, dirt is flowed less than ground, thereby free from environmental pollution.Originally scrape cleaning device and be installed on the mouth of pumped oil well (14), so just can successfully in well workover shadoof process, finish simultaneously and scrape the operation of washing dirt on bar (pipe) the part outer wall with threaded joint (13).Handle (5) and hoisting nut (7) are the annexes of this device.

Owing to taked technique scheme and be the necessary a series of technical measures of this scheme of enforcement, thereby reached the utility model proposes " design a kind of on pumpingh well in well workover lifting arm (pipe) part; just can in well head, the dirt on bar (pipe) the part outer wall be scraped wash clean, accomplish scrape the work of washing time saving and energy saving, not only saved cleaning rod (pipe) part expense, but also " cylinder outer wall dirt is scraped cleaning device " of not polluting ground environment " the purpose of utility model.

Claims
