Embodiment Construction
[0010] Embodiments of the present invention: the structure of the present invention is as figure 1 As shown, it comprises the original furnace coal bunker 1 and the belt conveyor for loading coal to the original furnace coal bunker. In the original belt conveyor, the original motor 6 is extended to the direction of its tail wheel), so that it is arranged on the same straight line with the original furnace coal bunker 1 on the coal belt conveyor transmission line with the original furnace coal bunker 1, and then Extend the belt of the original belt conveyor in reverse (i.e. from the direction of the original motor 6 to its tail wheel in the original belt conveyor) to the new furnace coal bunker 4, and replace the tail wheel as the driven wheel in the original belt conveyor with A runner 5 driven by an electric motor;
[0011] The structure of the present invention when working is as figure 2 As shown, the coal is first conveyed to the reformed belt conveyor 2 on the belt 3 b...

The present invention discloses a method for modifying the coal feeding system of a new-established furnace coal cabin. The new-established furnace coal cabin is constructed on a reversing extension line of the coal feeding belt pulley of the original furnace coal cabin; the belt of the original belt pulley is extent to the new-established furnace cabin in the reversing direction, and the tail wheel that is used as a driven wheel in the original belt pulley is substituted by a rotation wheel that is driven by a motor; when feeding the coal to the original furnace coal cabin, the driving wheelin the original belt pulley rotates, and the motor of the new-replaced rotation wheel is not electrified; when feeding the coal to the new-established furnace coal cabin, the motor of the new-replaced rotation wheel is electrified for running, so that the rotation wheel is operated as a driving wheel, and the original motor is not electrified. Two rollers that are driven by a motor are installed on one belt pulley, so that the belt pulley can feed the coal in two directions, and can send the coal to the new-established furnace coal cabin, thereby simplifying the coal feeding system, being convenient to be modified and being easy to be constructed; moreover, no belt pulley is added, thereby saving the land occupation area of the coal feeding system, and greatly reducing the modification cost.
Description
technical field [0001] The invention relates to a reforming method, in particular to a reforming method for a coal loading system of a new coal bunker. Background technique [0002] When factories and mines in aluminum industry and electric power industry are expanding, it is often necessary to transform the coal loading system. In the past, the transformation method of the coal feeding system was mainly to add a belt conveyor to the coal bunker that needs to be expanded, so as to achieve the purpose of conveying coal to the newly built coal bunker. However, the implementation cost of this method is relatively high, and the structure of the coal feeding system is complicated and occupies a large area. Contents of the invention [0003] The object of the present invention is to provide an economical and easy-to-implement coal loading system transformation method for newly built furnace coal bunkers. of floor area. [0004] The technical solution of the present invention ...
