Abstract

The invention relates to an agent-feeding device improvement structure which at least comprises two fixing posts. A fixing plate is arranged on the fixing posts. A round through hole is formed in the middle of the fixing plate. A tank body penetrates through the round through hole and is fixed to the fixing plate. The top of the tank body is provided with at least two feeding inlets. The outlet ends of the feeding inlets are arranged oppositely. A discharging pipe is arranged at the bottom of the tank body and provided with a valve. A roller wheel is arranged at the bottom of each fixing post. A supporting plate is hinged to the lateral wall of each fixing post. A spiral plate is arranged in the tank body. Inflection points of the spiral plate make contact with the inner wall surface of the tank body. The lower end of each layer of the spiral plate is provided with though holes. The problems that operation is inconvenient in an existing agent adding mode and an extra blending device needs to be added to an existing agent-feeding device are solved through the agent-feeding device improvement structure.

Description

technical field [0001] The invention relates to the technical field of petroleum machinery auxiliary tools, in particular to an improved structure of a dosing device. Background technique [0002] In the process of oil extraction, with the development and use of oil wells, the surface gathering and transportation pipelines of oil wells and downhole production strings are corroded to varying degrees, and the frequency of pipeline corrosion and perforation events is increasing year by year. Carry out dosing anticorrosion. Because the effectiveness of preservatives will weaken over time, it is necessary to refill preservatives every once in a while for adding preservatives to a single well. [0003] The existing dosing method is to configure the dosing concentration in the dosing device of the base. Since the dosing device in the base is bulky and inconvenient to move, it is necessary to inject the medicine into a container tank with a drain pipe. Place the container tank on ...
