[0002] In the metallurgical and mining industry, after the ore is crushed and pulverized, the crushed stone is transported. Before entering the mill, the crushed stone is pre-selected to remove a large amount of waste stone. The waste stone is dewatered by a high-frequency screen and the undersize material flows by gravity through an inclined chute and is collected together with the magnetic tailings in the plant and sent to the tailings dam.
[0003] Patent application number CN202022790117.8 discloses a construction sand beneficiation sluice for extracting construction sand from tailings. It includes a column with a spiral groove installed on it. The column has a through hole leading to the spiral groove, and a cutting groove is fixedly installed at the bottom of the spiral groove. The column is solid from the through hole downwards. A circular funnel is fixedly installed at the top of the column, and a mixing tank is fixedly installed at the top of the circular funnel. A feed chute is fixedly installed on the side of the mixing tank. To improve the separation effect, some sluices have guide cones at the discharge nozzle. To ensure that the guide cones can effectively cope with the impact of stones, they are mostly designed to be fixed. However, because the intervals are fixed, blockages often occur during long-term discharge, which needs to be optimized. Utility Model Content

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an anti-blocking tailings chute device, including a chute plate 4, the edge of the chute plate 4 is provided with a retaining edge 1, and the inner side of the chute plate 4 is provided with a plurality of triangular protrusions 41, and each triangular protrusion 41 is longitudinally and continuously distributed at the bottom of the chute plate 4.
[0024] The triangular protrusion 41 extends to both side walls to form a closed support frame. Specifically, the height of the triangular protrusion 41 is 1 / 3 to 1 / 2 of the depth of the chute plate 4, and the width of the base of the triangular protrusion 41 is 1.5 to 2 times its height. The apex of the triangular protrusion 41 is rigidly connected to the side wall of the retaining edge 1 by continuous welding or bolts to form a pressure-resistant node. The surface of the triangular protrusion 41 is overlaid with a tungsten carbide layer with a thickness of 2-5 mm or inlaid with a ceramic liner.
[0025] When the slurry flows through the triangular protrusion 41, the velocity gradient at the bottom increases, forming turbulence, which lifts the settling particles and thus prevents blockage. In addition, the triangular protrusion 41 and the baffle 1 form a closed frame to disperse lateral pressure and improve the structural strength of the chute plate 4.
[0026] The bottom of the chute plate 4 is provided with a discharge nozzle 5. The connection between the discharge nozzle 5 and the chute plate 4 is provided with a flow guiding mechanism. The flow guiding mechanism includes multiple flow guiding cones 6. The flow guiding cones 6 are located on the inner side of the chute plate 4. The bottom of the flow guiding cone 6 is provided with a plug rod 61. The plug rod 61 is fixedly connected to the flow guiding cone 6. The chute plate 4 is provided with a through hole that allows the plug rod 61 to slide and rotate.
[0027] The bottom of the chute plate 4 is provided with a sealing frame 7, and the sealing frame 7 is provided with a worm gear adjusting component for controlling the rotation of the plug rod 61. The worm gear adjusting component is detachably connected to the plug rod 61.
[0028] When the ore is discharged from the bottom of the chute plate 4 into the discharge nozzle 5, the guide cone 6 at the bottom of the chute plate 4 will divert the ore. The angle of the guide cone 6 is adjusted by the worm gear adjustment component. The worm gear adjustment component itself has self-locking properties, ensuring that the guide cone 6 can effectively cope with the impact of the ore without deflection after the adjustment is completed, thus improving the stability of the guide after adjustment.
[0029] It is worth explaining in detail that the plug-in rod 61 includes a polygonal prism and a cylindrical connector on top of the polygonal prism. The cylindrical connector is fixedly connected to the guide cone 6 and the polygonal prism, and is used in conjunction with the through hole. When installing the guide cone 6, the plug-in rod 61 at the bottom of the guide cone 6 is inserted into the through hole. The polygonal prism of the plug-in rod 61 is used to connect with the worm gear adjusting component, and the cylindrical connector of the plug-in rod 61 is used to connect with the chute plate 4. The cylindrical connector is inserted into the through hole, supporting the rotation and up-and-down insertion and removal of the plug-in rod 61.
[0030] Regarding worm gear adjusting components:
[0031] The worm gear adjusting component includes two worms 72 and two worm wheels 73. The worm wheels 73 and worms 72 are rotatably disposed inside the sealing frame 7. Each worm wheel 73 meshes with each worm 72. A rotating head 71 is provided on the outside of the sealing frame 7. The rotating head 71 is fixedly connected to the worm 72. The worm wheel 73 is detachably connected to the plug rod 61.
[0032] The swivel head 71 is rotatably mounted outside the sealing frame 7. Rotating the swivel head 71 causes the worm gear 72 inside the sealing frame 7 to rotate as well. The worm gear 72, in conjunction with the worm wheel 73, drives the worm wheel 73 to rotate. During rotation, the worm wheel 73 drives the guide cone 6 to rotate via the plug rod 61, adjusting the angle of the guide cone 6. The worm gear drive has a self-locking property. When the swivel head 71 stops rotating, the engagement of the threads between the worm gear 72 and the worm wheel 73 prevents the guide cone 6 from deflecting even if the ore on the chute plate 4 impacts it, thus improving the flow distribution stability of the guide cone 6. The swivel head 71 can be driven by a motor to control the rotation of the worm gear 72; this will not be discussed further here.
[0033] To facilitate the removal of the guide cone 6, the worm gear 73 is detachably connected to the connector rod 61. Specifically, the worm gear 73 has a polygonal insertion hole 74 at its center, which slides into a polygonal prism. A threaded post 62 is located at the bottom of the polygonal prism and is fixedly connected to the connector rod 61. The threaded post 62 is threadedly connected to a nut 8 located below the worm gear 73. The connector rod 61 is inserted into the polygonal insertion hole 74, which engages with the polygonal prism. Rotating the worm gear 73 causes the guide cone 6 to rotate via the polygonal prism. To prevent the connector rod 61 from falling off, after assembling the connector rod 61, the nut 8 below the worm gear 73 is screwed onto the outside of the threaded post 62. The nut 8 tightens the worm gear 73, fixing the screw head 71 to the worm gear 73. An anti-loosening washer 81 is placed between the nut 8 and the worm gear 73 to increase friction and improve connection stability.
[0034] Multiple guide channels 52 are provided on the inner side of the discharge nozzle 5. The guide channels 52 are connected to the discharge pipe 51 located at the lower end of the discharge nozzle 5. The guide channels 52 are staggered from the guide cone 6. The curved movement of the material on the chute plate 4 generates centrifugal force. The centrifugal force is greater on the outer side than on the inner side. The material with low density and fine particle size is more significantly affected by the centrifugal force and tends to move to the outer side of the trough. The material with high density is closer to the inner side due to inertia. Under the guidance of the guide cone 6, materials of different densities will enter the respective guide channels 52 to complete the separation of tailings.
[0035] To improve the stability of the chute plate 4, multiple support rods 3 are provided on the outer side of the chute plate 4. The support rods 3 are fixedly connected to the retaining edge 1, and reinforcing ribs 2 are provided at the connection between the support rods 3 and the retaining edge 1. The chute plate 4 is supported by the support rods 3, which are rigidly connected to the retaining edge 1 by welding or bolts.
[0036] How this application works:
[0037] The curved motion of the material on the chute plate 4 generates centrifugal force, with the centrifugal force being greater on the outer side than on the inner side. Materials with lower density and finer particle size are more significantly affected by centrifugal force and tend to move towards the outer side of the chute. Materials with higher density, due to inertia, move closer to the inner side. Guided by the guide cone 6, materials of different densities enter the respective guide channels 52, completing the tailings separation. When the slurry flows through the triangular convex ridge 41, the velocity gradient at the bottom increases, creating turbulence and lifting settled particles, thus preventing clogging. As the ore is discharged from the bottom of the chute plate 4 into the discharge nozzle 5, the guide cone 6 at the bottom of the chute plate 4 diverts the ore. The angle of the guide cone 6 is adjusted by a worm gear adjusting component, which has self-locking properties, ensuring that the guide cone 6 can effectively withstand the impact of the ore without deflection after adjustment, improving the stability of the flow after adjustment.
