Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel silos, in particular to a steel silo conveying device. Background Art
[0002] In the process of modernization, modern industry and agriculture are developing rapidly, and steel silos used to store bulk materials such as coal, ore, cement, grain, and oil are becoming more and more important. In order to ensure that the stored materials in the steel silo can flow fully, the design company often designs the bottom of the steel silo into a slope shape to facilitate the flow of materials to the central discharge port. We call the slope at the bottom of the steel silo a fill slope. The fill slope material is generally plain concrete, foam concrete or other lightweight aggregate materials. The fill slope is located in a large-volume closed steel silo, and the construction material transportation channel has only one steel silo discharge port with a diameter of about 1m. If a large number of people gather in the confined space for construction, they may suffer from heat stroke, hypoxia, etc., which has a high safety risk and certain construction difficulties.
[0003] Conventional slope filling construction usually involves making wooden formwork outside the warehouse, and then transporting the formwork to the warehouse for installation. To fix the formwork, holes are first drilled on the steel warehouse, and then the steel warehouse and the formwork are tightened with tension bolts. When pouring concrete, holes are drilled on the steel warehouse wall, and the concrete transport pipe flows into the warehouse through the holes on the warehouse wall. After the slope filling construction is completed, the holes on the warehouse wall are repaired, and the wooden formwork needs to be removed.
[0004] It can be seen from this that the above construction method uses wooden formwork and tension bolts, which will result in many holes on the side walls of the steel silo. Therefore, it can only be used for general slope filling construction. If there are strict requirements on the airtightness of the steel silo, holes cannot be opened on the silo wall at will, so the above-mentioned wooden formwork slope filling construction cannot be used.
[0005] In this regard, we use brick membrane to build the slope. The brick membrane can be integrally formed with the concrete pouring, so there is no need to drill holes in the side wall of the steel silo to fix it. However, for the transportation of brick membrane, workers manually transport construction materials into the steel silo in the existing technology, which is difficult to transport and increases the labor intensity of workers.
[0006] Therefore, there is an urgent need in the art for a steel silo conveying device to solve the above-mentioned problems. Utility Model Content
