Description

Technical Field

[0001] This utility model belongs to the technical field of grain storage equipment, specifically relating to the structure of a shallow circular silo with a low grain surface device. Background Technology

[0002] Shallow circular silos are a commonly used storage facility in grain storage. According to the "Design Standard for Reinforced Concrete Silos GB50077-2017", straight ladders should not be installed inside shallow circular silos. At the same time, according to the "Safety Regulations for Dust Explosion Prevention in Grain Processing, Storage and Transportation Systems GB 17440-2008", when grain is loaded into a shallow circular silo, its interior belongs to Zone 20, which means that during normal operation, grain dust is continuously or frequently present, and the amount is sufficient to form a combustible dust-air mixture and / or may form an uncontrollable and extremely thick dust layer.

[0003] Currently, for shallow circular silos that are not fully filled with grain, existing technology lacks a method for operating below the grain surface that both meets relevant safety standards and effectively avoids safety hazards. If operators directly enter the grain pile, there is a risk of the grain pile collapsing and burying personnel; and the use of some electrical equipment in this dusty environment poses a risk of dust explosion. Utility Model Content

[0029] The upper inner side of the shallow circular silo wall 202 is provided with a cantilevered grain inspection and observation platform 203, and the windlass winch 103 is installed on the cantilevered grain inspection and observation platform 203;

[0030] One end of the wire rope 104 is connected to the suspended basket 105, and the other end passes around the fixed pulley block 102 and is connected to the winch 103.

[0031] Furthermore, the pulley hook 101 is pre-embedded inside the shallow circular granary roof 201 directly above the cantilevered grain inspection and observation platform 203.

[0032] Furthermore, the fixed pulley group 102 is provided in two sets. The steel wire rope 104 passes through the two fixed pulley groups 102 and is connected to the winch 103. In this embodiment, the winch is used in conjunction with the two fixed pulley groups for manual winching, so that the suspended basket moves up and down along the inner side of the warehouse wall.

[0036] Furthermore, the winch 103 is specifically a manually operated mechanical winch.

[0037] In practical use:

[0038] 1) When it is necessary to carry out the operation of lowering the grain surface in the shallow round silo, one operator enters the suspended basket, and another operator manually rotates the winch to slowly lower the suspended basket to the required grain surface height in conjunction with two sets of fixed pulleys. The operator can adjust the height of the suspended basket at any time according to the actual situation.

[0039] 2) After the operation is completed, the operator manually rotates the winch in the opposite direction to raise the suspended basket to the top of the bin;

[0040] 3) Maintenance and upkeep: Regularly inspect and maintain the device, including checking the rotation of the pulley block, the wear of the wire rope, the working condition of the winch, and the fixing of the pulley block hooks. If any parts are found to be worn or damaged, they should be replaced or repaired in a timely manner to ensure the safe and reliable operation of the device.

[0041] The entire process of this plan is carried out manually, eliminating the risk of powder explosion and ensuring that people's feet do not directly contact the grain pile, thus preventing the danger of the grain pile collapsing and burying people.
