Description
Technical Field
[0001] The utility model relates to the technical field of iron removers, in particular to a sprocket connection structure of an iron remover. Background Art
[0002] Coal mine iron remover is a device that uses the principle of magnetic field adsorption to remove iron impurities in coal. Its main components include a magnetic source and an iron unloading device. When coal passes through the magnetic field area of the iron remover, the ferromagnetic substances in it will be attracted by the magnetic field and adsorbed on the iron remover, thereby separating from the coal. Coal mine iron removers are widely used in flotation, magnetic separation, coal preparation and other processes in the coal industry to remove impurities such as iron and dust from coal, ensure production safety, and improve coal quality.
[0003] Coal mine iron removers require sprockets and transmission chains to drive rollers, thereby driving the conveyor belt to run, and cooperate with magnets to achieve the purpose of iron removal by adsorption. When the coal preparation plant is in production, since the raw coal contains a large amount of debris and scrap iron, in order to ensure the normal operation of subsequent processes, the iron needs to be cleaned in advance. However, some coal mine iron removers are generally driven by a single sprocket and a single chain. In actual production, the iron remover transmission chain is still easily affected by debris, causing breakage, restricting normal production. If it is not resolved, it will affect production efficiency. If the single sprocket and single chain are changed to double sprockets, the stress strength will be greatly improved. The existing single sprocket and double sprocket are both fixed structures, and the sprockets cannot be combined with each other. If a double sprocket is required, it is necessary to replace the single sprocket and purchase a separate double sprocket, which increases the cost. Therefore, the utility model proposes a sprocket connection structure for an iron remover to solve the problems existing in the prior art. Utility Model Content
