Furthermore, a flow blocking ring is arranged in the tank body and is positioned below the defoaming device.

Further, the fire fighting equipment includes a plurality of defoaming subassemblies, and every defoaming subassembly includes a pair of entrapment board and a pair of defoaming board, parallel arrangement about the entrapment board, forms the foam chamber between the two boards, and the entrapment board is connected respectively to the defoaming board, and the distance between two defoaming boards reduces gradually and forms the compression chamber, and the defoaming board is still connected the guide plate and is used for exporting the liquid in the compression chamber.

Furthermore, the length of the guide plate is the same as the length of a liquid outlet of the compression cavity, and the distance between the end part of the guide plate and the inner wall of the pipe body is greater than the width of the flow blocking ring.

Furthermore, a liquid outlet formed by the guide plate is arranged downwards.

Furthermore, the stirring shaft is divided into a plurality of sections, the adjacent sections are connected by adopting a coupler, and a support plate is arranged below the coupler and used for guiding and radially supporting the stirring shaft.

According to the above technical scheme, the utility model has the advantages of it is following: the trapping plate can trap a large amount of bubbles under the high-speed rotation of the rotating shaft, and the bubbles enter the compression cavity to be crushed into liquid, and the liquid is discharged after being guided by the guide plate. The high-speed rotation requirement of the defoaming device can be ensured by arranging the speed reducer, and the low-rotation speed requirement of the stirring shaft can be met
