Description

A kind of high-efficiency and environment-friendly construction field derusting equipment for the outer wall of pipes

technical field

The invention relates to the technical field of pipeline maintenance, in particular to a rust removal device for the outer wall of a pipeline used in the field of high-efficiency and environment-friendly construction.

Background technique

Architecture is a general term for buildings and structures. It is an artificial environment created by people in order to meet the needs of social life, using the material and technical means they have mastered, and using certain scientific laws, feng shui concepts and aesthetic laws. In order to clearly express the usability, some classifications distinguish buildings from non-building structures that people do not occupy for a long time. In order to avoid confusion, some architectural scholars deliberately include the appearance of buildings created by people consciously. Divided into Architecture. Note that sometimes buildings may also be extended to include "non-building structures" such as bridges, pylons, tunnels, etc.

Buildings have broad and narrow meanings. Buildings in a broad sense refer to all things artificially constructed, including both houses and structures.

Buildings in a narrow sense refer to houses, excluding structures. A house refers to a space with foundations, walls, roofs, doors and windows that can shelter from wind and rain for people to live, work, study, entertain, store items or perform other activities. Architecture-related majors mostly refer to the narrow meaning of buildings. The one who can best explain the concept of a building for majors in "architecture" is Lao Tzu's: "If you think of a utensil as a vessel, you should treat it as if it doesn't exist, and the vessel will be used for it. If you cut down a door and think of it as a room, treat it as if it doesn't exist, and you will use it as a room." , which is undoubtedly the clearest and most direct expression of the narrow building concept.

Different from buildings, structures have no internal space for people to use, and people generally do not directly carry out production and living activities in them, such as chimneys, water towers, bridges, dams, sculptures, pipes, etc.

A pipeline is a device for conveying gas, liquid or fluid with solid particles connected by pipes, pipe joints and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high pressure of the pipeline to the low pressure, and the fluid can also be transported by its own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.

At present, in construction, the surface rust removal of metal profiles is still carried out with a hand-held angle grinder. This manual rust removal method has the disadvantages of low work efficiency, high labor intensity, high damage rate of equipment and poor safety performance. , Although there is a mechanized building construction rust removal and grinding machine in the prior art, because the fixing device on it is fixed, it cannot be used for rust removal for pipes of different diameters.
