Metal cage for batch bolt multicomponent alloy co-permeation treatment

Abstract

The invention discloses a metal cage for batch bolt multicomponent alloy co-permeation treatment. The metal cage comprises a round rolling outer side wall of a tubular structure, one end of the round rolling outer side wall in the axial direction is open, the other end of the round rolling outer side wall in the axial direction is provided with a round rolling bottom wall, the round rolling bottom wall is provided with a round rolling inner side wall, the round rolling inner side wall is arranged at the inner side of a round rolling outer side wall, and the round rolling inner side wall and the round rolling outer side wall are coaxially arranged and provided with multiple hollowed-out permeation agent penetration holes; the metal cage further comprises a round rolling sealing cover arranged at one end of an axial opening of the round rolling outer side wall. By means of the metal cage, work efficiency is improved, and it is helpful to guarantee health and safety of operators.

Description

technical field [0001] The invention relates to the technical field of a bolt surface anticorrosion treatment tool for construction engineering, in particular to a metal cage for multi-element alloy co-infiltration treatment of batch bolts. Background technique [0002] The embedded parts of bridges with reinforced concrete structure are prone to corrosion and damage the concrete structure of the bridge due to long-term exposure to various corrosion-causing factors such as freezing damage, chemical corrosion, steel corrosion, and alkali-aggregate reaction; especially due to humidity The effect of carbon dioxide, temperature and carbon dioxide will cause the carbonization of concrete, and the effect of corrosive media such as oxygen, sulfur dioxide and chlorine will further aggravate the corrosion of bridge embedded parts and the damage of concrete structure. [0003] Multi-element alloy co-infiltration is a new type of metal anti-corrosion technology, which mainly forms an a...

Problems solved by technology

[0004] In the prior art, when bolts for construction engineering are subjected to multi-component alloy co-infiltration treatment, it is usually necessary to mix the bolts with multi-component alloy co-infiltration agent and fill them into the co-infiltration furnace, and then close the co-infiltration furnace for rotary heating co-infiltration treatment. After the heating co-infiltration treatment is completed, the bolts mixed with the co-infiltration agent are sorted out. The disadvantage of the above operation process is that the temperature of the bolts mixed with the co-infiltration agent just taken out of the co-infiltration furnace is relatively high. It can only be sorted after being placed for a period of time for natural cooling, so the operation cycle is long and the work efficiency is low; in addition, when the bolts mixed with the infiltration agent are placed in the working environment for natural cooling and sorting operations, the The co-penetration agent dust will disperse, pollute the working environment and endanger the health and safety of workers
