The fire receiving pot 1 can collect and clean high-temperature welding slag generated in the process of fire operation, so as to reduce the possibility of fire caused by falling high-temperature welding slag and harm to the safety of construction personnel. The hanging piece 2 can be detachably connected with the fire receiving pot 1, so that the fire receiving pot 1 is quickly and conveniently mounted at the steel beam connection. Compared with welding the hanging piece 2 on the fire receiving pot 1, the efficiency is higher and the disassembly is more convenient.

The fire receiving pot 1 is box-shaped and is made of multiple metal plates welded together. The length direction of the fire receiving pot 1 is horizontally arranged. The lower part of the end face of the fire receiving pot 1 is inclined to the inside of the fire receiving pot 1, so that the side wall of the fire receiving pot 1 is in the shape of an inverted isosceles trapezoid. The bottom of the fire receiving pot 1 is rotationally provided with a movable door 11. The movable door 11 closes the bottom of the fire receiving pot 1. The length direction of the movable door 11 is parallel to the length direction of the fire receiving pot 1. The side end face of the movable door 11 is hingedly connected with the side of the bottom of the fire receiving pot 1 through a hinge.

[0034] Combined with Figure 1And Figure 2 The surface of the movable door 11 away from the fire pan 1 is provided with a lock plate 111 which is a strip-shaped plate. The lock plate 111 is provided with two plates which are parallel to each other and are spaced apart. The lock plate 111 is away from the hinge and is located at the surface edge of the movable door 11. The plate surface of the lock plate 111 is perpendicular to the surface of the movable door 11. The end of the lock plate 111 away from the movable door 11 is inclined in the direction away from the hinge. A lock hole is formed on the plate surface of the lock plate 111.

When the movable door 11 is closed, the movable door 11 will close the bottom of the fire pan 1. Rotating the hinge column 12 will drive the curved lock rod 14 to be inserted into the lock hole of the lock plate 111, thereby locking the movable door 11. This reduces the possibility of the welding slag falling from the bottom of the fire pan 1 when the fire pan 1 is collecting the welding slag. After the fire pan 1 is used for a period of time or is disassembled, the hinge column 12 can be rotated to separate the curved lock rod 14 from the lock plate 111, thereby unlocking the movable door 11. The welding slag collected in the fire pan 1 can be transferred from the bottom of the fire pan 1 for processing, which facilitates the subsequent use and disassembly of the fire pan 1.
