High-flame-retardant steel fireproof door filled with dispersion strengthening base body

Abstract

The invention discloses a high-flame-retardant steel fireproof door filled with a dispersion strengthening base body. The high-flame-retardant steel fireproof door comprises a fireproof door frame. Fireproof door plates are mounted inside the fireproof door frame. Fireproof plates are fixedly connected to the inner sides of the protective door plates. A bolt is mounted in a cavity. The inner sideend of the bolt and the inner wall of the cavity are connected with two symmetrical compression springs. Rotating handles are fixedly mounted at the ends of the rotating shafts through the surfaces ofthe fireproof door plates. Rectangular grooves are formed in one ends of the fireproof plates. The interior of the fireproof plate is of a hollow structure. A heat dissipation device is mounted in the fireproof plate. The top of the frame is fixedly connected with a cooling box. A cooling pipe is arranged in the frame. The top of the cooling box is connected with a cooling pipe water outlet. Thebottom end of the cooling pipe water outlet communicates with a cooling pipe. The water inlet of the cooling pipe, the cooling pipe, the water outlet of the cooling pipe and the water-cooling circulating pipe are communicated to form a circulating water-cooling system, resources do not need to be obtained from the outside, the heat dissipation device is simplified, the water-cooling effect is improved, the cooling effect of the fireproof door is improved, and the service life of the fireproof door is prolonged.

Description

technical field [0001] The invention belongs to the technical field of fire doors, in particular to a high fire-resistant steel fire door filled with a dispersion-strengthened matrix. Background technique [0002] With the rapid development of social economy, fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke, which can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel. [0003] However, the existing steel fire doors cannot be flame-retardant, impact-proof, heat-dissipating, and do not meet the existing needs. For this, we propose a high flame-retardant steel fireproof door filled with a dispersion-strengthened matrix. Door.
