Description

Technical Field

[0001] The utility model relates to the technical field of a rigid storage decompression device, in particular to a rigid storage decompression device for powdery materials. Background Art

[0002] Powdered materials usually refer to those fine granular substances, such as cement, lime, milk powder, powdered sugar, etc. In industrial production, these materials need to be properly stored and handled to ensure their quality and safety. They are generally stored in rigid storage tanks. Powdered materials need to be decompressed in rigid storage tanks. The main purpose of decompression is to ensure a stable supply of materials, prevent excessive pressure from causing poor material transportation or safety hazards, and prevent pipeline blockage. When powdered materials are transported in pipelines, if the pressure is too high, it is easy to cause material accumulation in the pipeline, resulting in pipeline blockage. Decompression can reduce the chance of blockage.

[0003] The existing rigid storage decompression device is prone to clogging the pressure relief port due to the small powder particles, resulting in the inability to effectively discharge the pressure in the storage tank; the existing rigid storage decompression device has poor fluidity of the powder in the tank due to the accumulation of powder, and is easy to agglomerate, affecting the discharge efficiency. Therefore, a rigid storage decompression device for powdered materials is proposed to address the above problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1.
