[0002] In the production process of the flame retardant, the extruder is one of the commonly used equipment, which is used for extruding the flame retardant material into shape, and the flame retardant material needs to be cooled after extrusion. The traditional cooling method often adopts direct water cooling. Although the direct water cooling can quickly reduce the temperature of the flame retardant, the cooling speed is too fast, which may cause stress in the flame retardant, and the flame retardant is prone to breakage during discharging, thereby affecting the subsequent cutting and granulating process. In addition, although the simple air cooling can reduce the probability of occurrence of the problem, the cooling effect is relatively weak, and the cooling speed is slow, which may not meet the demand of efficient production.

[0003] In order to solve the above problems, it is necessary to design a discharging mechanism which can quickly and effectively cool the flame retardant and avoid the quality problems caused by rapid cooling. CONTENT OF THE UTILITY MODEL
