It is an equipment system in the professional field of mineral classification. The basic structure of hydraulic classifier is circular, and the main body is composed of an upper cylinder and a lower cone.

[0003] The nozzle of the existing hydraulic classifier is directly opposite to the feed pipe, and the water discharged from the nozzle surges upward. The surging water pushes the slurry upward, causing the slurry to be pushed back into the feed pipe, which is not conducive to the slurry classification treatment. When a large amount of slurry is discharged from the feed pipe at the same time, a large pressure is generated on the water flow at the nozzle, reducing the slurry classification effect. Therefore, a uniform feeding hydraulic classifier is proposed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] See also Figure 1-4A uniform feeding hydraulic classifier comprises an inner cone barrel 1 and an outer barrel 15. A feed pipe 2 is arranged at the top of the inner cone barrel 1, and diverter pipes 3 are fixed on both sides of the feed pipe 2. The center line of the inner cone barrel 1 and the center line of the feed pipe 2 are located on the same straight line, and the bottom of the feed pipe 2 is concave inward. The slurry is injected into the inner cone barrel 1 through the feed pipe 2 and the diverter pipe 3. This arrangement facilitates the diversion of the slurry into the inner cone barrel 1 and facilitates the subsequent classification of the slurry. A high-pressure water pipe 4 is arranged in parallel below the feed pipe 2, and a nozzle 5 is installed on the upper surface of the high-pressure water pipe 4. A discharge port 6 is arranged at the bottom of the inner cone barrel 1. The number of nozzles 5 is equal to the number of shunt pipes 3, and the nozzles 5 are arranged just below the end of the shunt pipe 3. The water flows out from the nozzles 5 and surges upward. The slurry discharged from the shunt pipe 3 encounters the surging water flow. Under the impact of the water flow, the slurry is stratified. The discharge valve on the discharge port 6 is opened. The heavier slurry resists the impact of the water flow and is discharged from the discharge port 6. The lighter part mixed in the slurry floats upward with the water flow, thus realizing the grading treatment of the slurry. The opening of the shunt pipe 3 is perpendicular to the nozzles 5. This setting can prevent the water flow from flushing the slurry back to the shunt pipe 3, which is conducive to the rapid stratification of the slurry. The left side of the inner cone barrel 1 is provided with A high-pressure water pump 7 is arranged, and a connecting water pipe 8 is arranged on one side of the high-pressure water pump 7, and a water delivery pipe end 9 is integrated on the other side of the high-pressure water pump 7, and a flange 10 is fixed on the outside of the right end of the water delivery pipe end 9, the left end of the high-pressure water pipe 4 passes through the inner cone barrel 1 and is connected to the water delivery pipe end 9 of the high-pressure water pump 7, and the top edge of the inner cone barrel 1 is arranged in an arc shape, which is convenient for the lighter part of the slurry to overflow from the top of the inner cone barrel 1, and the connecting water pipe 8 is connected to the external water source. Under the setting of the high-pressure water pump 7, the water flow is sent into the high-pressure water pipe 4 and discharged from the nozzle 5, and a flange 2 11 is installed on the right side of the flange 10, and the flange A threaded hole is provided inside the edge of the flange 10 and the flange 2 11, and a screw 12 is passed through the threaded hole. A circular groove 13 is provided inside the right side of the flange 2 11, and a sealing ring 14 is installed inside the circular groove 13, and the sealing ring 14 is fixedly connected to the flange 10. The water delivery pipe end 9 on the high-pressure water pump 7 is connected to the high-pressure water pipe 4 through the arrangement of the flange 10, the flange 2 11 and the screw 12. The connection sealing between the flange 10 and the flange 2 11 is enhanced by the arrangement of the circular groove 13 and the sealing ring 14, thereby reducing the probability of water leakage at the left end of the high-pressure water pipe 4, which is beneficial to the transportation of water;

[0024] The outer barrel 15 is welded to the outside of the inner cone barrel 1, and a drain port 16 is provided on the lower surface of the outer barrel 15. A connecting rod 17 is welded to the top of the outer barrel 15. The end of the connecting rod 17 away from the outer barrel 15 is welded to the outer wall of the feed pipe 2, and the upper surface of the outer barrel 15 is higher than the upper surface of the inner cone barrel 1. The connecting rod 17 provides stable support for the feed pipe 2. The slurry overflowing from the top of the inner cone barrel 1 falls into the outer barrel 15 and is discharged through the drain port 16.

[0025] Working principle: When in use, first connect the connecting water pipe 8 to the external water source, start the high-pressure water pump 7, send water into the high-pressure water pipe 4 and discharge it from the nozzle 5, inject the slurry into the feed pipe 2, and the slurry in the feed pipe 2 is discharged from the two branch pipes 3. Since the number of nozzles 5 is equal to the number of branch pipes 3, and the nozzles 5 are arranged directly below the ends of the branch pipes 3, the water is discharged from the nozzles 5 and surges upward. When the slurry falls, it encounters the surging water flow. Under the impact of the water flow, the slurry is stratified. The heavier slurry resists the impact of the water flow and descends to be discharged from the discharge port 6. The lighter part mixed in the slurry floats upward with the water flow until it overflows from the top of the inner cone barrel 1 and falls into the outer barrel 15, and is finally discharged through the drainage port 16, thereby realizing the grading of the slurry.
