A high-temperature rotary heating device for bolt surface treatment

Abstract

The invention discloses a high-temperature rotation heating device for bolt surface processing. The high-temperature rotation heating device for the bolt surface processing comprises a rotation heating tank, wherein the rotation heating tank is of a closed cylindrical structure and comprises a heating tank bottom wall and a heating tank seal cover. A centralized processing cage is arranged in the rotation heating tank and comprises a round rolling outer side wall of a tubular structure, a round rolling bottom wall, a round rolling inner side wall and a round rolling seal cover; a plurality of hollowed permeating agent permeable holes are formed in the round rolling inner side wall and the round rolling outer side wall; hollow synchronous rolling limiting holes are formed in the round rolling seal cover and the round rolling bottom wall correspondingly and formed in the inner side of the round rolling inner side wall; synchronous rolling fixation holes are formed in the heating tank bottom wall and the heating tank seal cover; and the centralized processing cage further comprises synchronous rolling connection rods with the two ends located inside the synchronous rolling fixation holes and the middle portions penetrating through the synchronous rolling limiting holes.

Description

technical field [0001] The invention relates to the technical field of bolt surface treatment equipment for construction engineering, in particular to a high-temperature rotary heating equipment for bolt surface treatment. Background technique [0002] Bolts used in construction projects in reinforced concrete structures such as bridges are prone to corrosion and damage to concrete structures 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 and damage of the concrete structure. In order to improve the corrosion resistance of bolts used in construction engineering, multi-element alloy co-infiltration anti-corrosion treatment measu...

AI Technical Summary

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 bolts located at the axis of the co-infiltration furnace are not in sufficient contact with the multi-component alloy infiltration agent. The effect of multi-component alloy co-infiltration treatment of bolts is not good or the time of multi-component alloy co-infiltration treatment needs to be prolonged; in addition, when the bolts mixed with co-infiltration agent are placed in the working environment for natural cooling and sorting operations, multi-component alloy co-infiltration Penetrating agent dust will drift away, polluting the working environment and endangering the health and safety of workers
