Description

Technical Field

[0001] The utility model belongs to the technical field of chain conveying, and in particular relates to an anti-tilt chain conveying device. Background Art

[0002] Chain conveyor is a mechanism that uses chains to pull and carry materials, or uses slats, metal mesh belts and rollers installed on the chains to carry materials. Its advantages are: 1) Large conveying capacity, allowing large amounts of materials to be transported in a small space, with a conveying capacity of 6m 3 / h~600m 3 / h. 2) Low energy consumption for transportation. With the help of the internal friction of the material, the material is pushed into a pull, which saves 50% of electricity compared with the screw conveyor. 3) Sealed and safe. It can be placed in a fully sealed casing so that dust can not be drilled through. It is safe to operate and reliable. 4) Long service life. The conveyor chain made of alloy steel by advanced heat treatment methods has a normal life of >5 years, and the roller life of the chain (depending on different materials) is ≥2-3 years. 5) Flexible process layout. It can be arranged on an elevated, ground or pit. It can be installed horizontally or climbing (≤15°). It can also be installed horizontally and climbing on the same machine. It can be fed in and out of multiple points. 6) Low cost of use, power saving and durable, less maintenance, low cost (about 1 / 10 of the screw conveyor mechanism), can ensure the normal operation of the main machine to increase output, reduce consumption and improve efficiency.

[0003] For the high-temperature environments where torpedo tankers are located, after long-term use, the high temperature will cause uncertain changes in the length of the chain. Since the chain conveying mechanism generally uses two chains for synchronous conveying, if the two chains are of unequal lengths, the synchronization of the conveying mechanism will be affected, and may even cause accidents such as tipping. The existing structure needs to be upgraded. Utility Model Content
