Oil pipe dosing device

Abstract

The invention discloses an oil pipe dosing device. The oil pipe dosing device comprises a round pipe, a drum is placed in the round pipe, a spray head and blades are mounted on the drum, a driving mechanism is arranged below the round pipe, a shell is welded to the upper part of the round pipe, a plurality of supporting rods are welded to the upper end of the drum, and one ends of the multiple supporting rods are connected with round covers; a plurality of clamping teeth are welded to the positions of one third of the outer sides of the round covers at equal distances correspondingly, a cylinder and a first spring are welded to one side of the inner wall of the shell, the cylinder is provided with a long plate in a sleeved mode, an extrusion block is welded to the other end of the long plate, a plurality of tooth grooves are formed in one side of the long plate at equal distances, an opening is formed in the upper part of the shell, and a box body is placed in the shell in the mode ofpenetrating through the opening; and a feeing device is formed above the box body, and a buffering mechanism is arranged on one side of a rotating plate. The device is reasonable in design and easy tooperate, a motor drives the extrusion block at one end of the long plate to extrude the rotating plate, then a sealing block can be separated out of a through opening, and therefore liquid medicine can be conveniently conveyed into the drum through a sliding groove to be sprayed out through the spray head.

Description

Technical field[0001]The invention relates to the technical field of a tubing dosing device, in particular to a tubing dosing device.Background technique[0002]In petroleum exploration projects, crude oil generally contains a large amount of wax. When the crude oil flows out of the oil well, because the temperature and pressure are reduced, the wax will quickly precipitate from the crude oil, and these precipitated waxes are easy to adhere to the wall of the oil pipeline , Blocking the oil pipeline, reducing the transportation capacity of the oil pipeline or even completely blocking the phenomenon.[0003]In order to prevent the tubing from clogging, some drugs such as corrosion inhibitors, scale inhibitors, fungicides and wax inhibitors are usually added to the tubing. Nowadays, most of the drugs are manually added to the tubing, which is time-consuming and laborious, reduces work efficiency, and brings great inconvenience to work. For this reason, we have proposed a tubing dosing dev...

Problems solved by technology

[0002]In petroleum exploitation engineering, crude oil generally has a large wax content. When crude oil flows out of the oil well, the wax will be precipitated from the crude oil rapidly due to the decrease in temperature and pressure. The precipitated wax is easy to adhere to the pipe wall of the oil pipeline, block the oil pipeline, reduce the delivery capacity of the oil pipeline or even completely block the phenomenon

[0003]In order to prevent oil pipes from clogging, some drugs such as corrosion inhibitors, scale inhibitors, fungicides and anti-wax agents are usually added to the pipelines. It is time-consuming and labor-intensive, which reduces work efficiency and brings great inconvenience to the work. For this reason, we propose a oil pipe dosing device, which can automatically add medicine to the oil pipe at equal intervals;
