This invention discloses an adaptive cyclic control method for ash discharge valves in a sintering machine's main flue gas duct bulk material handling system, relating to the technical field of ash discharge valve control methods. The method includes the following steps: identifying ash discharge valves in the system that frequently experience material blockage and marking them as easily blocked ash discharge valves; establishing independent control logic, creating an independent control logic module for the marked easily blocked ash discharge valves in the central control unit of the bulk material handling system; setting a dedicated cycle T1 shorter than the system's main cycle time for the independent control logic module; independent parallel control operation, with the main control program continuing to control ash discharge valves other than the easily blocked ash discharge valves according to the system's main cycle time; simultaneously, the independent control logic module runs in parallel, driving the easily blocked ash discharge valves to start and stop cyclically according to the dedicated cycle T1. This overcomes the shortcomings of existing systems that easily lead to local valve blockage and high equipment wear, achieving independent and precise control of easily blocked ash discharge valves.

This invention discloses a three-dimensional motion automatic material handling, lifting, and precise delivery system for bulk materials, relating to the field of bulk material handling and delivery technology. It includes a material pool with a first support fixed to its top. A movable frame is housed within the first support, and a movable block is housed within the movable frame. A first telescopic component is mounted on the top of the movable block, and a material handling cylinder is located at the output end of the first telescopic component.

This invention relates to the field of bulk material handling equipment, and particularly to a bucket wheel mechanism that facilitates easy cleaning and unloading. It includes a wheel body and multiple buckets circumferentially arranged on the wheel body. Each bucket has multiple circumferentially arranged teeth at its front open end. Each bucket includes an upper bucket body, an upper flapper plate, scrapers, a lower flapper plate, and a tilting drive component. The lower flapper plate is located at the bottom of the upper bucket body and is hinged to the rear end of the upper bucket body via a hinge structure. The top of the upper bucket body has an opening, and the upper flapper plate is hinged to this opening. Scrapers are located on both sides of the upper flapper plate, and these scrapers are in contact with the inner walls of the upper bucket body. The tilting drive component is hinged to the outside of the upper bucket body, and its output end is hinged to the upper flapper plate. The tilting drive component drives the upper flapper plate to open or close. When the upper flapper plate tilts, the scrapers on both sides scrape away any sticky material accumulated on the inner surfaces of the upper bucket body. This invention achieves "instant cleaning of accumulated material and rapid unloading," while reducing the number of idle cycles of the bucket wheel mechanism and lowering equipment energy consumption.

This invention relates to the field of large bulk material handling machinery, specifically to a device and method for correcting the deviation of a movable beam in a bucket wheel excavator. The device comprises a movable beam, a trolley, a traveling wheel frame with electromagnets, a magnetorheological elastomer pad, a main drive hydraulic cylinder, cross-connected antagonistic hydraulic cylinders, and a controller. The system calculates the resistance-thrust-stiffness mismatch index through the controller. When the index exceeds a threshold, the electromagnets are triggered to generate an upward suction force to reduce the contact normal pressure on the traveling wheels, and simultaneously reduce the elastic modulus of the pad to release lateral restraint. Its core principle is to utilize electromagnetic attraction and a variable stiffness pad to synergistically reduce drag, which, in conjunction with the main drive hydraulic cylinder, pushes the movable beam for lateral repositioning. This invention abandons the traditional rigid lateral pushing method under heavy loads, significantly reducing the thrust required for lateral repositioning, effectively solving the problems of easy stick-slip jumping and stress concentration, and achieving smooth deviation correction.
