Abstract
Description
Technical Field
[0001] The present application relates to the technical field of jigs, and in particular to an energy dissipation pipe for a fine-grained jig concentrate pipe. Background Art
[0002] Fine Jigs are used to classify mixtures of different materials by creating water movement (pulsation) so that the materials in the jig are clearly separated according to density. The jig capacity ranges from 5 tons / hour to 700 tons / hour. Materials from 150 mm to less than 1 mm can be effectively separated.
[0003] In the process of fine particle jig, the air chamber is connected to the shell through the cavity, and in the connected containers, the liquid surface in each container is always at the same height. If the jig is idle, the jig chamber will be completely filled with water, while the air chamber will only be partially filled with water. If the jig is in operation, compressed air is periodically applied to the air chamber through the air inlet. The air required for the pulsation of the water is generated by a rotary piston fan with an electric drive and stored in a compressed air container. The air supply and extraction are controlled by a powered rotary piston valve or a poppet valve.
[0004] Compressed air is alternately applied to the air chamber during oscillation and then discharged to the outside. Due to the repeated application of compressed air and exhaust, the upper space in the air chamber is filled and the water in the air chamber is pressed downward into the interior of the cavity. The amount of water from the air chamber increases the liquid level in the cavity of the jig screen bed. Due to the periodic application of air, the amount of water described previously fluctuates up and down between the cavity and the air chamber. Therefore, the liquid level of the liquid in the worktable area rises and falls in synchronization with the application of compressed air to the air chamber. In the feed area, a certain amount of material to be separated is filled above the screen bed. Due to the periodic upward and downward movement of the liquid level, the layer is in a relaxed state similar to a fluidized bed. The particles are layered according to their density, that is, light materials float on the water surface above the screen bed, and heavier materials sink to the lower part of the screen bed in the water. Since the screen bed has a certain inclination, the material moves in the direction of discharge under the pulsation of the water. The heavy material forms an accumulation layer, the height of which is measured by a float. The light material flows into the discharge port together with the water, and the heavy particles are discharged to another outlet at the lowest point. Depending on the sorting task, further material may be selected, for example medium-weight particles can be discharged through a hopper at the bottom of the jig.
[0005] In the use of fine-grained jigs, the concentrate pipe at the outlet of heavy materials will leak due to excessive wear after a period of use, and each replacement will take a lot of time, which will not only increase the workload of maintenance personnel, but also reduce the operation rate and start-up rate of the equipment due to equipment downtime and maintenance. Therefore, it is necessary to provide a fine-grained jig concentrate pipe energy dissipation pipe. Utility Model Content

Figure 1-2Embodiment 1, the fine-grained jig concentrate pipe energy dissipation pipe in the present application includes an energy dissipation structure 1 and an energy dissipation pipe shell 2. The energy dissipation structure 1 is placed in the energy dissipation pipe shell 2. The energy dissipation structure 1 moves freely forward and backward in the energy dissipation pipe shell 2. The energy dissipation pipe shell 2 is composed of a slurry inlet 3, an intermediate structure 4, and a slurry outlet 5. The slurry inlet 3 is connected to the fine-grained jig slurry outlet pipe, and the slurry outlet 5 is connected to the concentrate pipe slurry inlet pipe, so that the slurry in the fine-grained jig is reduced in speed by the energy dissipation pipe before flowing into the concentrate pipe, effectively avoiding damage to the concentrate pipe and improving its service life. The slurry inlet 3 and the slurry outlet 5 form a conical structure to provide sufficient slurry for flowing into the energy dissipation pipe. The deceleration space is that the slurry flows from the small aperture into the large aperture channel, and the slurry has a certain buffer space in the energy dissipation pipe, so that the slurry can be decelerated in the large aperture and can effectively avoid blockage in the energy dissipation pipe. The intermediate structure 4 is a cylindrical structure, and the large diameter ends of the slurry inlet 3 and the slurry outlet 5 are respectively connected to the two ends of the intermediate structure 4 by flanges and bolts, which is convenient for disassembly of the slurry inlet 3 and the slurry outlet 5, so that the replacement and maintenance speed of the energy dissipation structure 1 is increased; the energy dissipation structure 1 includes an energy dissipation plate group 6 and a spacer rod 7. The energy dissipation plate in the energy dissipation plate group 6 is set in a circular ring shape, and the circular outer ring of the energy dissipation plate and the energy dissipation pipe shell 2 form a closed space, which effectively The slurry flow rate is reduced, and the slurry that cannot pass through collides with the plate baffle and returns, and the returned slurry collides with the slurry flowing in from the rear end again, thereby reducing the flow rate of the slurry at the rear end. At the same time, the slurry flows through the annular inner hole of the energy dissipation plate after the speed reduction, and the diameter of the annular inner hole of the energy dissipation plate is larger than the diameter of the smallest end of the slurry inlet 3 and the slurry outlet 5, which effectively avoids the slurry blockage inside the energy dissipation pipe; the energy dissipation plate group 6 includes a first energy dissipation plate 8, a second energy dissipation plate 9, a third energy dissipation plate 10, and a fourth energy dissipation plate 11. The diameters of the first energy dissipation plate 8, the second energy dissipation plate 9, and the third energy dissipation plate 10 increase successively, so that the first energy dissipation plate 8, the second energy dissipation plate 9, and the third energy dissipation plate 11 are 10 adapts to the change of the diameter of the energy dissipation pipe shell 2, the diameter of the fourth energy dissipation plate 11 is the same as the diameter of the third energy dissipation plate 10, and the diameter of the fourth energy dissipation plate 11 is smaller than the diameter of the intermediate structure 4, so that the entire energy dissipation plate group 6 can be installed in the intermediate structure 4, and at the same time, the gap between the energy dissipation plate in the energy dissipation plate group 6 and the shell of the intermediate structure 4 is reduced, so that the energy dissipation plate group 6 can fully exert the slurry deceleration function; the first energy dissipation plate 8, the second energy dissipation plate 9, the third energy dissipation plate 10, and the fourth energy dissipation plate 11 are connected to each other by the spacer rod 7, so that the first energy dissipation plate 8, the second energy dissipation plate 9, the third energy dissipation plate 10, and the fourth energy dissipation plate 11 form a whole.
[0028] In Example 2, at least four energy dissipation plates are arranged on the energy dissipation plate group 6 in the energy dissipation structure 1 of the present application. When the wear in the concentrate pipe is still very large, energy dissipation plates are added to the energy dissipation plate group 6 to reduce the slurry flow rate further.
[0029] Embodiment 3: In the present application, at least four spacer rods 7 are arranged between every two energy dissipation plates on the energy dissipation structure 1, so that the connection between the energy dissipation plates is more stable.
[0030] Example 4, in the present application, a threaded rod 12 is arranged at the end of the spacer rod 7, and the diameter of the threaded rod 12 is smaller than the diameter of the spacer rod 7. The fourth energy dissipation plate 11 is fixed to the spacer rod 7 by the threaded rod 12 and the positioning nut 13, so that it is more convenient and quick to add energy dissipation plates to the energy dissipation plate group 6.
