Detailed Description
The invention aims to improve the dismantling and installing efficiency of a hopper and reduce the forced downtime of a production line.
The bucket elevator is a whole set of system, wherein the steel wire adhesive tape is conveying equipment, the hoppers are fixedly arranged on the steel wire adhesive tape by bolts, and the two hoppers are uniformly spaced by 150mm. The fixture is that two channel-section steel are buckled together in opposite directions, punches on the channel-section steel, passes two channel-section steel and steel wire sticky tape with the bolt to fastening clamp steel wire sticky tape. The bucket elevator is a shell surrounded by four external surfaces, and the cutting holes are 1.2 x 1.5m square holes and are positioned on the shell on the conveying surface and the two side surfaces of the steel wire adhesive tape.
A speed reducer with a non-return function (MC 3RLHF and a speed ratio 48.9626 in the invention) is purchased, the maximum reverse torque is 34.2KN.m, a motor of the bucket elevator is connected with the speed reducer through a hydraulic coupler to drive a roller, the inner side of a steel wire adhesive tape covers the roller, the steel wire adhesive tape is driven to run through friction, the reverse force is 34.2KN.m, the capacity of the steel wire adhesive tape is matched with the design load of the whole equipment, the arrangement cannot be adjusted, and the speed reducer only uses a clamp to clamp the position of the steel wire adhesive tape in the middle of a hopper at the cutting hole of a platform at the next layer of the head pulley, so that the hopper is prevented from rotating in the reverse direction.
The forward rotation side of the bucket elevator head wheel firstly removes 3-5 hoppers, the speed reducer keeps receiving a reverse force, and the hoppers are synchronously removed at the position of the diagonal cutting holes of the platform at the lower layer of the head wheel and the tail wheel, so that the hoppers are removed in sequence. When the material is returned to the material hopper, 3 to 5 material hoppers are firstly arranged in the reverse direction of the tail wheel, then diagonal operation is carried out at the cutting holes of the head wheel and the tail wheel, and the material hoppers are arranged in sequence.
Examples:
The bucket elevator steel wire adhesive tape replacement method is used in the replacement process of the bucket elevator steel wire adhesive tape in the ultrafine powder operation area of the Taisteel processing plant, and the efficiency is obviously improved by using the improved hopper disassembly and assembly method.
