Description

Technical Field

[0001] This utility model relates to a spiral chute device, and more particularly to a high-efficiency sorting spiral chute device. Background Technology

[0002] In the field of mineral sorting, spiral sluices, as an important gravity separation device, are widely used in the beneficiation of minerals such as iron ore, tungsten ore, and tin ore. Traditional spiral sluices mainly rely on the flow of slurry within the spiral sluice to achieve stratification and separation of mineral particles of different densities due to differences in gravity, centrifugal force, and friction. They are mainly used for the separation of fine-grained ores, and are particularly suitable for the separation of minerals with large density differences, such as iron ore, tungsten ore, tin ore, and tantalum-niobium ore.

[0003] Traditional spiral sluices lack an effective dewatering structure, and excessively thin slurry can lead to insufficient stratification of mineral particles, affecting sorting accuracy and efficiency.

[0004] Therefore, it is necessary to design a high-efficiency spiral chute device that can optimize slurry dewatering and improve separation stability. Utility Model Content

[0005] The technical solution of this utility model is: a high-efficiency sorting spiral chute device, including three supports and a spiral chute disposed between the three supports. The spiral chute is arranged along the axial direction of the supports. The spiral chute includes a chute bottom and a chute frame. The chute frame includes an outer chute frame side and an inner chute frame side. A baffle is provided on the bottom of the chute. Notches are provided at both ends of the baffle where it connects with the outer and inner chute frame sides. Notches are also provided on the outer and inner chute frame sides at positions corresponding to the baffle. Filter screens are provided at the notches. The upper end of the spiral chute is the feeding end, and the lower end is the discharging end. A collection frame is connected to the lower discharging end of the spiral chute. Dividing plates are evenly spaced inside the collection frame, dividing the collection frame into multiple areas to sort the material at the discharging end.

[0006] Furthermore, fixed rods are spaced apart on the bottom of the spiral chute at its lower end. The fixed rods correspond to the positions of the partition plates. A guide plate is movably mounted on the fixed rod, and a spring is installed between the upper end of the fixed rod and the guide plate.

[0007] Furthermore, a sliding block is provided between the lower end of the spring and the guide plate, the fixed rod moves through the sliding block, and the lower end of the spring is connected to the sliding block.

[0008] Furthermore, the sliding block is made of rubber.

[0009] Furthermore, the guide plate is designed as an isosceles triangle.

[0010] Furthermore, discharge pipes are spaced apart at the bottom of the collection frame, and the discharge pipes are connected to the bottom inside the collection frame.

[0011] Furthermore, connecting frames are connected to the notches on both the outer and inner sides of the chute frame, and water guide pipes are connected to the bottom of the connecting frames. A water collection tank is installed at the bottom of the spiral chute, and the lower end of the water guide pipe extends into the water collection tank.

[0012] The beneficial effects are: 1. By setting baffles inside the spiral chute, and opening gaps at corresponding positions on the outer and inner chute frames and baffles, and setting filter screens at the gaps, the water and extremely fine particles in the slurry are effectively filtered through the filter screens at the gaps in the chute frame under the blocking effect of the baffles and discharged, flowing into the water collection tank through the water pipe, thereby reducing the water content of the slurry, improving the stratification effect of mineral particles, and enhancing the sorting accuracy.

[0013] 2. A movable guide plate is installed at the end of the spiral chute, and in conjunction with a spring and sliding block structure, the guide plate can automatically adjust its angle according to the slurry flow or impact force, ensuring that the material is evenly distributed to different areas of the collection frame and improving the sorting stability.

Detailed Implementation

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] Example: A high-efficiency sorting spiral chute device, such as Figures 1-4As shown, the system includes three supports 100 and a spiral chute 1 positioned between them. The spiral chute 1 is arranged along the axial direction of the supports 100. The spiral chute 1 includes a chute bottom 103 and a chute frame. The chute frame includes an outer chute frame side 101 and an inner chute frame side 102. A baffle 2 is provided on the chute bottom 103. The baffle 2 is located on the upper part of the spiral chute 1 and is arranged in a "V" shape. Notches are provided at both ends of the baffle 2 where it connects with the outer chute frame side 101 and the inner chute frame side 102. Notches are also provided at corresponding positions on the outer chute frame side 101 and the inner chute frame side 102. Filter screens 3 are provided at the notches of the outer chute frame side 101 and the inner chute frame side 102. The upper end of the spiral chute 1 is the feeding end, and the lower end is the discharging end. The baffle 2 is located near the feeding port. A collection frame 11 is connected to the lower discharging end of the spiral chute 1. The collection frame 11 is evenly spaced with partition plates 12, which divide the collection frame 11 into multiple areas to sort the material at the discharge end. The bottom of the collection frame 11 is spaced with discharge pipes 13, which are connected to the bottom inner side of the collection frame 11. In use, the slurry is fed in from the top of the spiral chute 1. When the slurry flows to the baffle 2, the liquid in the slurry flows out through the gaps of the outer chute frame 101 and the inner chute frame 102 under the blocking effect of the baffle 2. The filter screen 3 filters the slurry to prevent the ore from flowing away through the gaps of the outer chute frame 101 and the inner chute frame 102. When the slurry flows into the collection frame 11 from the discharge end of the spiral chute 1, the collection space is divided into multiple independent areas by the partition plates 12. Therefore, minerals of different densities can be collected separately through the collection frame 11.

[0021] like Figure 1 and Figure 4 As shown, fixed rods 8 are spaced apart on the bottom 103 of the spiral chute 1. The fixed rods 8 correspond to the positions of the partition plate 12. A guide plate 7 is rotatably mounted on the fixed rods 8. The guide plate 7 is an isosceles triangle. A spring 10 is installed between the upper end of the fixed rod 8 and the guide plate 7. A sliding block 9 is installed between the lower end of the spring 10 and the guide plate 7. The fixed rod 8 moves through the sliding block 9, and the lower end of the spring 10 is connected to the sliding block 9. The sliding block 9 is made of rubber. When the material is guided by the guide plate 7, if the material is large, the material will push the guide plate 7 to rotate a certain angle around the fixed rod 8. The cooperation of the spring 10 and the sliding block 9 ensures that the guide plate 7 effectively fits the bottom 103 of the spiral chute 1, ensuring the stability of the material guiding function of the guide plate 7. The guide plate 7 adopts an isosceles triangle design, and the sliding block 9 is made of rubber, which not only ensures the smoothness of the flow, but also buffers the impact of the slurry and extends the service life of the equipment.

[0022] like Figure 1 and Figure 3As shown, a connecting frame 4 is connected to the notch of the outer chute frame 101 and the inner chute frame 102. A water guide pipe 5 is connected to the bottom of the connecting frame 4. A water collection tank 6 is provided at the bottom of the spiral chute 1. The lower end of the water guide pipe 5 extends into the water collection tank 6.

[0023] In operation, the slurry is fed evenly from the top (feeding end) of the spiral chute 1 and flows downwards along the chute. Under the combined action of gravity, centrifugal force, and friction, mineral particles of different densities stratify: high-density minerals (such as iron ore and tungsten ore) flow close to the inner chute frame edge 102 due to their greater inertia; low-density minerals (such as gangue and light impurities) move along the outer chute frame edge 101 due to the influence of centrifugal force. When the slurry flows through the baffle 2, because there are gaps at both ends of the baffle 2 where they meet the chute frame edge, and filter screens 3 are installed at these gaps, some water and extremely fine particles (such as sludge) are discharged through the filter screen 3, enter the connecting frame 4, and then flow into the water collection tank 6 through the water guide pipe 5. This reduces the water content of the slurry in the spiral chute 1, thereby improving the subsequent separation efficiency and preventing the slurry from being too thin, which would affect the separation accuracy. When the slurry flows from top to bottom to the discharge end of the spiral chute 1, the slurry is evenly distributed to different areas of the collection frame 11 by the guide plate 7, and then flows to different collection frames for collection through the discharge pipe 13. When the flow rate or impact force changes, the guide plate 7 can rotate a certain angle along the fixed rod 8 to optimize the material distribution and improve the sorting stability.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
