Technical Field

[0002] Shuttle-type material feeders are used in the feeding operation of sintering processes. After the materials are mixed, they are fed onto the conveyor belt of the material feeder and fall into the trough. During the use of shuttle-type material feeders, large foreign objects often accumulate on the grid due to impurities in the sintering mixture. Traditional cleaning methods generally require manual cleaning, which is time-consuming, labor-intensive, and poses high safety risks.

[0003] Therefore, it is necessary to develop targeted methods for cleaning bar screens to efficiently and quickly remove large pieces of material from them. Summary of the Invention

[0006] 1) The belt of the shuttle fabric carrier feeds material to the hopper. The feed grid on the hopper intercepts large pieces of material, and the large pieces of material accumulate at the drop point to form a material accumulation.

[0007] 2) The accumulated material pushes open the material overflow movable plate inside the machine head cover, triggering the material overflow detection switch control system to control the shuttle cloth carriage to move backward, and the backward distance is L1;

[0008] 3) The impurity removal device moves down along the movable guide rail under the push of the hydraulic cylinder. After the downward movement is completed, the control system controls the main body of the shuttle cloth carrier to move forward. The forward distance is L2. The large pieces of material are pushed from the drop point to the impurity area through the triangular structure impurity removal device.

[0009] 4) After the large pieces of material are cleaned up, the impurity removal device moves up along the movable guide rail under the pull of the hydraulic cylinder, the main body of the shuttle cloth car returns to the original working position, and the belt continues to feed material into the hopper.

[0010] 5) Periodically stop the shuttle fabric carriage and its belt, and clean up large pieces of material in the debris area.

[0011] In step 2), L1 = 1.5L, where L is the width of the head cover.

[0012] In step 3), L2 = 4L, where L is the width of the head cover.

[0013] The data for L1 and L2 are obtained through a Gray bus or encoder continuous positioning detection device.

[0014] The main body of the shuttle fabric carriage is equipped with a triggering structure and a cleaning structure inside the head cover. The triggering structure includes a material overflow movable plate and a material overflow detection switch. The cleaning structure includes a hydraulic cylinder base, a hydraulic cylinder and a cleaning device connected in sequence. The cleaning device has a triangular structure and moves up and down within the range of the movable guide rail.

[0015] The triggering structure and the cleaning structure are located below the discharge end of the belt of the shuttle fabric carrier.

[0016] The triggering structure and the cleaning structure are located above the material drop point of the feed and cleaning grid on the bin.

[0017] The side of the material drop point is a debris area.

[0018] The triggering structure and the cleaning structure are respectively connected to the control system of the shuttle fabric carriage body.

[0019] Beneficial Effects: Compared with existing technologies, this invention has the following significant advantages: This invention is applicable to scenarios where bulk materials containing impurities are fed into a silo via a shuttle feeder and filtered through a grid. Large pieces on the feed grid of the mixing silo are promptly pushed from the central drop point to the impurity area at the grid edge, preventing obstruction of the sintered mixing material and avoiding overflow. It can efficiently and quickly clean large pieces of material from the grid, improving the operating efficiency and cleaning effect of the unloading vehicle. Through automated operation of the control system, it replaces manual cleaning work, reducing labor intensity and eliminating operational safety risks. Attached Figure Description
