Description

Technical Field

[0001] The utility model relates to the technical field of silo doors, in particular to a manual door for a silo. Background Art

[0002] Silos are crucial storage facilities at ports and terminals. Silo doors are a crucial component of these facilities, serving as the sole entrance and exit for workers to clear the silos and maintain equipment. However, with age, these doors are facing issues such as rust and leakage, safety hazards, and operational difficulties.

[0003] Due to long-term use and natural aging, the silo's manual doors showed obvious wear and aging, leading to a series of problems: rust on the door and water leakage. This caused the bulk grain stored in the silo to clump and other cargo damage problems, which not only affected the quality of the goods, but also may lead to additional clearance work and losses.

[0004] The artificial door is aging and poses a safety hazard: Due to aging, the bolts of the artificial door are loose and the airtightness is poor, which brings hidden dangers to the fumigation operation of the silo, and then leads to an increase in the workload of sealing the warehouse and a waste of materials. When sealing the warehouse, the door needs to be sealed with glass glue, which not only increases the workload of sealing and clearing the warehouse, but also wastes a lot of materials.

[0005] Due to the design of the old manual door, the silo door was made of multiple heavy steel plates, which made closing and opening the door inconvenient. This not only increased the labor intensity of the staff, but also could lead to operational errors and safety risks. In summary, the problems of the manual door of the silo not only affected the quality of goods and safe production, but also increased the difficulty and cost of work. Therefore, it was necessary to update and improve the manual door of the silo. Utility Model Content
