Description

Technical Field

[0001] The utility model relates to the technical field of centrifuge equipment, in particular to a discharging mechanism of a horizontal centrifuge. Background Art

[0002] The horizontal centrifuge uses the high-speed rotating drum to generate centrifugal force to trap the solid particles in the suspension in the drum and automatically discharge them out of the machine under the action of force; at the same time, the liquid in the suspension is thrown out through the filter medium and the small holes of the drum, thereby achieving the purpose of liquid-solid separation and filtration.

[0003] The discharge mechanism of the currently used horizontal centrifuge usually can adjust the angle of the discharge shell through a threaded sleeve and a threaded rod, so that the staff can adjust the angle of the discharge shell according to different materials, thereby avoiding the material remaining on the surface of the discharge shell and affecting the discharge effect, thereby improving the discharge efficiency.

[0004] However, this method cannot screen the materials when used. If the discharge mechanism cannot screen the materials of unqualified size, these materials will be discharged together with the separated products. The unqualified materials will cause these materials to block the discharge port or damage the discharge mechanism itself during the discharge process, which will increase the maintenance cost and downtime of the equipment and reduce the continuity and efficiency of production.

[0022] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a discharging mechanism of a horizontal centrifuge, comprising a support frame 1, a screening box 2 is fixedly connected to the upper part of the support frame 1, a motor 4 is fixedly connected to the right part of the screening box 2, a rotating shaft 5 is fixedly connected to the output end of the motor 4, cams 6 are fixedly connected to the outer sides of the rotating shaft 5, connecting rods 7 are fixedly connected to the opposite sides of the two cams 6, and screening components are fixedly connected to the bottoms of the two connecting rods 7. The screening component is used to screen materials. The screening component includes a screen frame 8, which is fixedly connected to the connecting rod 7. The bottom of the connecting rod 7 and the bottom of the screen frame 8 are fixedly connected with an electric push rod 10, the output end of the electric push rod 10 is fixedly connected with a screen plate 9, the screen plate 9 is rotatably connected to the inside of the screen frame 8, the upper part of the screening box 2 is fixedly connected with a feed hopper 3, the bottom of the screening box 2 is fixedly connected with a discharge hopper 13, the left part of the screening box 2 is fixedly connected with a discharge hopper 11, the screen frame 8 is slidably connected to the inside of the screening box 2, the inside of the screening box 2 is fixedly connected with a guide plate 12, the guide plate 12 is arranged at the lower part of the screen frame 8, and a discharge port is opened inside the guide plate 12.

[0024] The material is accurately fed into the interior of the screening box 2 through the feed hopper 3. When the motor 4 is started, its output end begins to drive the rotating shaft 5 to rotate. As the rotating shaft 5 rotates, the cam 6 also rotates accordingly. The rotation of the cam 6 is transmitted to the screen frame 8 through the connecting rod 7, so that the screen frame 8 moves up and down inside the screening box 2. This up and down movement causes the sieve plate 9 in the sieve frame 8 to also produce corresponding up and down vibrations. The vibration of the sieve plate 9 can effectively screen the material, so that the qualified material can fall down smoothly. During the screening process, the qualified material falls into the inside of the discharge hopper 13 through the discharge port inside the guide plate 12. For the unqualified materials, they will remain on the upper part of the sieve plate 9. At this time, the electric push rod 10 can be started. The output end of the electric push rod 10 can push the sieve plate 9, so that the sieve plate 9 rotates inside the sieve frame 8. When the sieve plate 9 is tilted to a certain angle, the material on its upper part can be smoothly discharged outward through the discharge hopper 11.

[0025] Reference Figure 1 and Figure 2 Cylinders 16 are fixedly connected to both sides of the upper part of the support frame 1, and the output ends of the two cylinders 16 are fixedly connected to movable plates 17, and movable rods 18 are fixedly connected to both sides of the bottom of the movable plate 17. The bottom of the movable rod 18 is fixedly connected to a baffle 14, and the baffle 14 is slidably connected to the inside of the discharge hopper 13. A mounting frame 15 is fixedly connected to the upper part of the support frame 1, and two movable rods 18 are slidably connected to the inside of the mounting frame 15. A buffer spring 19 is sleeved on the outside of the mounting frame 15, and one end of the buffer spring 19 is fixedly connected to the upper part of the mounting frame 15, and the other end of the buffer spring 19 is fixedly connected to the bottom of the movable plate 17. A pad 20 is fixedly connected to the inside of the support frame 1, and a collecting box 21 is slidably connected to the upper part of the pad 20. The collecting box 21 is arranged at the lower part of the discharge hopper 13.

[0026] When the cylinder 16 is started, its output end pushes the movable plate 17 to move upward, and the movable plate 17 drives the movable rod 18 connected thereto to move together. As the movable plate 17 rises, the buffer spring 19 is gradually stretched, providing the necessary buffer and stability. Under the action of the movable rod 18, the baffle 14 begins to move upward. The baffle 14 was originally located inside the discharge hopper 13 to block the outflow of materials. When the baffle 14 moves upward and moves out of the discharge hopper 13, the materials are discharged smoothly through the discharge hopper 13, and the discharged materials then enter the interior of the collection box 21.

[0027] Working principle: first, the material enters the interior of the screening box 2 through the feed hopper 3, and the motor 4 is started. The output end of the motor 4 drives the rotating shaft 5 to rotate, and the rotation of the rotating shaft 5 drives the cam 6 to rotate, and the cam 6 drives the connecting rod 7 to move, and the connecting rod 7 drives the screen frame 8 to move up and down inside the screening box 2. When the screen frame 8 moves, it drives the screen plate 9 to move up and down. Under the action of the screen frame 8 and the screen plate 9, the material can be screened, and the qualified material falls downward, falls into the inside of the discharge hopper 13 through the discharge port inside the guide plate 12, and finally is discharged through the discharge hopper 13, and the unqualified material remains on the upper part of the screen plate 9. At this time, the electric push rod 10 is started, and the output end of the electric push rod 10 pushes the screen plate 9 to make the screen plate 9 rotate inside the screen frame 8. When the screen plate 9 is tilted, the material on the screen plate 9 is discharged outward through the discharge hopper 11, thereby realizing that the material can be effectively screened. Screening can accurately control the particle size of the discharged material according to the particle size requirements of the material, ensure that the material discharged from the centrifuge meets the predetermined particle size requirements, and ensure the uniformity and consistency of the product. When the material is ready to be discharged through the discharge hopper 13, the cylinder 16 is started, and the output end of the cylinder 16 pushes the movable plate 17 to move upward. The movement of the movable plate 17 drives the movable rod 18 to move. When the movable plate 17 moves, the buffer spring 19 is stretched. Under the action of the movable rod 18, the baffle 14 moves upward and moves out from the inside of the discharge hopper 13. The material can be discharged into the collection box 21 through the discharge hopper 13, and the material is collected and stored by the collection box 21, thereby realizing convenient and automatic unloading. The speed and method of discharging can be automatically adjusted, making the operation of the centrifuge more automated, reducing the need for manual intervention, and improving the convenience and efficiency of operation.
