Embodiment

[0038] A walk-in fireproof box self-closing door system, such as figure 1 As shown: the fireproof box 9 is a hazardous chemical storage box for personnel to enter and operate, and the fireproof box is provided with a hinged fireproof door 1,

[0039] like Figure 2 to Figure 4 As shown: the self-closing door system includes a door suction device 2 for controlling the opening and closing position of the fire door and a self-closing device 3 for driving the fire door to automatically close;

[0040] The door suction device includes a positioning rod 21 connected to the inside of the fire door and a brake 22 connected to the fire box. One end of the positioning rod is movably connected to the fire door, and the other end passes through the fire door. The connection port 221 of the brake and can slide in the connection port, and the brake is rotatably connected to the fireproof box;

[0041] The brake includes an electromagnetic coil 222 and a brake disc 223, the brake disc incl...

Abstract

The invention discloses a step-in type fireproof box self-door-closing system. A self-closing device for driving a fireproof door to be opened and closed and a door stop device for controlling and keeping the opening and closing state of the fireproof door. The self-closing device is driven by a motor and a gear. The motor drive and gear transmission efficiency is high, and door closing is rapid.The door stop device drives a brake disc to clamp or loosen a positioning rod through an electromagnetic coil, and accordingly the fireproof door can be stopped at any position. The strong clamping force can be obtained through electromagnetic coil control, and the fireproof door stop stability is guaranteed. Electromagnetic coil control can be matched with a protection system of the fireproof box, a door stop can be automatically released when accidents happen, the fireproof door is automatically closed, and the integral anti-explosion and fireproof performance is ensured.

Description

technical field [0001] The invention belongs to the technical field of storage of hazardous chemicals, in particular to a walk-in fireproof box. Background technique [0002] Hazardous chemicals need to be used in the process of teaching and scientific research, and the chemicals have the characteristics of a wide variety, a small number of single species, and a large amount. Pressure, anti-leakage, temperature adjustment, monitoring, anti-static, anti-corrosion, anti-leakage and other requirements, there are strict requirements for the storage and placement of hazardous chemicals. [0003] In the prior art, the various fireproof, explosion-proof, and anti-corrosion capabilities of hazardous chemical storage boxes have strict requirements on box materials and various safety configurations, and the automatic release and closing of fire doors in the event of accidents and the normal opening The function that needs to be kept at any time has not been well achieved in the prior...
