[0023] This utility model provides a desalination horizontal screw discharge sedimentation centrifuge.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The centrifuge includes a centrifuge base plate 1, with support legs fixedly connected to the four corners of the bottom of the centrifuge base plate 1. A desalination horizontal screw discharge sedimentation centrifuge body 2 is installed on the top of the centrifuge base plate 1. Four elongated slots are opened on the top of the centrifuge base plate 1. Two lead screws 17 are provided at the bottom of the centrifuge base plate 1. Fixed blocks are rotatably connected to the outer side of the two lead screws 17. The two fixed blocks are fixedly connected to the bottom of the centrifuge base plate 1. Opposite threads are opened at both ends of the outer side of the two lead screws 17. A forward and reverse motor is fixedly connected to the bottom of the centrifuge base plate 1. The output end of the forward and reverse motor is fixedly connected to one of the lead screws 17. Sprockets are fixedly connected to the outer side of the two lead screws 17. The two sprockets are connected to each other by chain drive. Limit rods 16 are connected to both ends of the outer side of the lead screws 17 by nut pairs. The limit rods 16 are set inside the elongated slots and slide in contact with the centrifuge base plate 1. A fixing component is provided at the top of the limit rods 16.

[0025] The fixing assembly includes a mounting frame 3, which is fixedly connected to the top of the centrifuge base plate 1. Two square cylinders 8 are fixedly connected to the top of the mounting frame 3. Each of the two square cylinders 8 has a movable plate 12 inside. Connecting blocks 13 are fixedly connected to opposite sides of each of the two movable plates 12. One end of each connecting block 13 passes through the inner side of the two square cylinders 8 and extends to the outer side of the two square cylinders 8. Both connecting blocks 13 are slidably connected to the two square cylinders 8. One connecting block 13 has a slot at one end, and the other connecting block 13 has a locking block 14 fixedly connected to one end, which is disposed inside the slot. The fixing assembly also includes two racks 5, each fixedly connected to the bottom end of the two movable plates 12. Both racks 5 are disposed inside the mounting frame 3, and sliding rods 4 are slidably connected to the inner side of each rack 5. All slide rods 4 are fixedly connected to the mounting frame 3. One of the movable plates 12 has a through hole 15 on its outer side. One slide rod 4 and one rack 5 are both set inside the through hole 15. A gear 7 is meshed between the two racks 5. A rotating rod 6 is fixedly connected to the inner side of the gear 7. The rotating rod 6 is rotatably connected to the inside of the mounting frame 3. A connecting rod 9 is fixedly connected to the outer side of one of the movable plates 12. One end of the connecting rod 9 passes through the inner side of the mounting frame 3 and extends to the outer side of the mounting frame 3. The connecting rod 9 is slidably connected to the mounting frame 3. A return spring 10 is sleeved on the outer side of the connecting rod 9. The two ends of the return spring 10 are fixedly connected to one of the movable plates 12 and the mounting frame 3, respectively. A limit frame 11 is fixedly connected to one end of the connecting rod 9. A pull handle is fixedly connected to the top of the limit frame 11. A limit rod 16 is set inside the limit frame 11.

[0026] Specifically, when it is necessary to disassemble the closed lifting ring, start the forward and reverse motors. There is no specific limitation on the model of the forward and reverse motors; the model should be based on the compatible equipment. The output end of the forward and reverse motors drives one of the lead screws 17 to rotate in the forward direction. The two sprockets are connected by chain drive, and the two lead screws 17 rotate synchronously.

[0027] The lead screw 17 drives the two limiting rods 16 to move in opposite directions, which in turn pulls the two limiting frames 11 to move in opposite directions, moving the limiting frames 11 away from the mounting frame 3. The connecting rod 9 drives one of the racks 5 to move through one of the moving plates 12. At this time, the return spring 10 sleeved on the outside of the connecting rod 9 is in an elastic compression state, and both racks 5 are engaged with the gear 7, thereby enabling the two racks 5 to drive the two moving plates 12 to move in opposite directions. The two connecting blocks 13 move into the two square cylinders 8 respectively, thereby releasing the limiting of the closed lifting ring. This structure allows multiple closed lifting rings to be disassembled simultaneously without the need for multiple disassemblies by personnel, thus improving the disassembly progress.

[0028] When installing the closed lifting ring, the operator simply pulls the handle outward, causing the limiting frame 11 to move the connecting rod 9. The return spring 10 is then compressed elastically, and one of the moving plates 12 on the connecting rod 9 moves, causing one of the racks 5 to mesh with the gear 7. Through the rotation of the gear 7, the two racks 5 move in opposite directions, and the two moving plates 12 respectively drive the two connecting blocks 13 to move into the two mounting frames 3. This allows the closed lifting ring to be placed between the two square cylinders 8. Loosening the handle causes the return spring 10 to return elastically, and the two connecting blocks 13 limit the position of the closed lifting ring, thus completing the installation of the closed lifting ring.
