[0056] During operation, adipic acid is stored inside the cylinder body 1. Since adipic acid will absorb moisture and caking, when in use, the caked adipic acid will block the passage between the cylinder body 1 and the conical shell 2 due to its large volume; at this time, as the amount of the blockage increases, the mass of the blockage will increase. When the pressure reaches the values preset by the remote pressure gauge I and the remote pressure gauge II, the annular pulse device I 3 and the annular pulse device II 4 start to start intermittently. The high-pressure nitrogen gas ejected by the annular pulse device I 3 and the annular pulse device II 4 impacts the blockage, dispersing the caked blockage. The material is crushed into fine particles by the crusher 6, and the fine particles are conveyed to a loss-in-weight scale for weighing; at the same time, when the current of the crusher 6 is lower than the normal current, it indicates that there is no material being crushed on the crusher 6, that is, the upstream material is blocked. The annular pulse device I 3 and the annular pulse device II 4 start to act, and are purged with high-pressure nitrogen gas to clear the blockage; when the dust is blown up by the annular pulse device I 3 and the annular pulse device II 4, it will enter the bag filter and be collected by the bag filter, avoiding the dust from entering the air and polluting the air, thereby maintaining the overall stability and cleanliness. When the current of the crusher 6 is normal, the annular pulse device I 3 and the annular pulse device II 4 stop acting, facilitating the flow of adipic acid crystals, enabling the material to stably enter the loss-in-weight scale, and then stably metering, avoiding affecting the quality of the product.
