Description

Technical Field

[0001] This utility model relates to the technical field of bag-lifting equipment, specifically a bag-lifting device for a bag-lifting centrifuge for unloading materials. Background Technology

[0002] The hanging bag discharge centrifuge is an intermittent filtration centrifuge widely used in the pharmaceutical, food, and chemical industries, primarily for solid-liquid separation. It consists of a drive unit, machine body, casing, drum, hanging bags, braking device, and clutch. Material is added to the drum from the top. Under centrifugal force, the liquid phase passes through the filter medium and is discharged, while the solid phase is retained inside the drum. After stopping, the hanging bag device lifts the filter bags out and transports them to a designated location for unloading. However, existing hanging bag devices have a fixed structure and are generally only suitable for centrifuges of a fixed model or size, making them less practical for centrifuges of different sizes.

[0037] Specifically, the hydraulic cylinder 120 facilitates the adjustment of the height of the movable shell 121 and the bag-lifting mechanism 200, and the bag-lifting mechanism 200, in conjunction with the hydraulic cylinder 120, facilitates the suspension and transfer of the centrifuge filter bags. Furthermore, the stabilizing mechanism 300 improves the stability of the bag-lifting device of the centrifuge with bag unloading, making it more convenient to use.

[0038] Example 1

[0039] like Figure 3-5As shown, in this embodiment, the bag-lifting mechanism 200 includes: a circular shell 210, a stepper motor 220, and a connecting shell 230. The circular shell 210 is fixedly connected to the movable shell 121, the stepper motor 220 is fixedly connected to the circular shell 210, a rotating plate 221 is fixedly connected to the output end of the stepper motor 220, and the rotating plate 221 is rotatably connected to the top of the circular shell 210. The connecting shell 230 is fixedly connected to the rotating plate 221, and a movable rod 233 is slidably connected inside the connecting shell 230, with one end of the movable rod 233... A suspension assembly is provided. A stepper motor 231 is fixedly connected to the inner wall of the connecting shell 230, and a screw 232 is fixedly connected to the output end of the stepper motor 231. The screw 232 is screwed into a moving rod 233. The suspension assembly includes a round rod 241 and a fixed plate 250. The round rod 241 is rotatably connected to the moving rod 233. The fixed plate 250 is fixedly connected to the round rod 241. Multiple connecting seats 251 are fixedly connected to the fixed plate 250, and connecting rods 252 are rotatably connected to the connecting seats 251. A hook 253 is rotatably connected to one end of the 52. A circular shell 260 is fixedly connected to the bottom of the fixing plate 250. Multiple push rods 261 are slidably connected to the circular shell 260, and one end of each push rod 261 is slidably connected to the interior of multiple connecting rods 252. A stepper motor 270 is fixedly connected to the inner top surface of the circular shell 260, and a bevel gear 271 is fixedly connected to the output end of the stepper motor 270. Multiple fixing blocks 280 are fixedly connected to the inner bottom surface of the circular shell 260, and a rotatably connected... A rotating rod 281 is fixedly connected to one end of a bevel gear 282, and multiple bevel gears 282 are screwed into bevel gear 271. A screw 283 is fixedly connected to the other end of the rotating rod 281, and the screw 283 is screwed into the corresponding push rod 261. A stepper motor 240 is provided on the top of the fixed plate 250. The stepper motor 240 is fixedly connected to the top of the moving rod 233, and the output end of the stepper motor 240 passes through the side wall of the moving rod 233 and is fixedly connected to the round rod 241.

[0040] In this embodiment, by activating stepper motor 231, the screw 232 is rotated, causing the moving rod 233 and the suspension assembly to move to the appropriate position. Stepper motor 270 then rotates bevel gear 271, which meshes with multiple bevel gears 282, causing multiple rotating rods 281 and multiple screws 283 to rotate. This, in turn, moves multiple push rods 261, which in turn pushes multiple connecting rods 252 to rotate, facilitating the adjustment of the positions of multiple hooks 253. This allows the bag-hanging mechanism 200 to be adapted to centrifuge filter bags of different sizes. The hydraulic cylinder 120 facilitates the adjustment of the height of multiple hooks 253. By starting the stepper motor 240, the positions of the round rod 241, the fixing plate 250, the multiple connecting rods 252, and the multiple hooks 253 can be adjusted, thus facilitating the hooks 253 to connect centrifuge filter bags of different sizes. The hydraulic cylinder 120 also facilitates the adjustment of the height of the bag-lifting mechanism 200, thus facilitating the suspension of the filter bags. Furthermore, by starting the stepper motor 220, the rotating plate 221 is rotated, thereby moving the connecting shell 230, the moving rod 233, the suspension assembly, and the filter bags to the appropriate positions, thus facilitating the transfer of the filter bags and making them more convenient to use.

[0041] Example 2

[0042] Based on Example 1, in order to improve the stability of the bag-lifting device of the bag-lifting centrifuge when transferring filter bags.

[0043] like Figure 6 As shown, in this embodiment, the stabilizing mechanism 300 includes: a rotating shell 310, a telescopic rod 320, a stepper motor 330, a counterweight 340, and multiple connecting blocks 350. The rotating shell 310 is rotatably connected to the fixed tube 110. The telescopic rod 320 is fixedly connected to the rotating shell 310. The top of the telescopic rod 320 is fixedly connected to the connecting shell 230. The stepper motor 330 is fixedly connected to the inner wall of the rotating shell 310. The output end of the stepper motor 330 is fixedly connected to a screw 331, and an adjusting rod 332 is screwed onto the outer side of the screw 331. The counterweight 340 is fixedly connected to the adjusting rod 332. Multiple connecting blocks 350 are all fixedly connected to the bottom of the counterweight 340, and a rotating ball 351 is rotatably connected to the bottom of each of the multiple connecting blocks 350.

[0044] In specific implementation, by starting stepper motor 330, the screw 331 is rotated, thereby moving the adjusting rod 332 and the counterweight 340 to the appropriate position. Multiple connecting blocks 350 and multiple rotating balls 351 can provide auxiliary support for the counterweight 340. The telescopic rod 320 allows the stabilizing mechanism 300 to move and rotate with the connecting shell 230, so that the counterweight 340 can change with the position of the suspension assembly. In this way, the stabilizing mechanism 300 improves the stability of the bag-lifting device of the bag-unloading centrifuge when transferring filter bags.
