Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a special lifting device for a disc-type separator. Background Art

[0002] A disc separator is a physical separation machine that separates incompatible materials of varying densities by generating different centrifugal forces. Due to its high separation factor and large throughput, it can process highly dispersed liquid-liquid two-phase turbidities and liquid-solid two-phase suspensions with very low solid-phase settling velocities, which are difficult for conventional centrifuges to effectively separate. It can also process liquid-liquid-solid three-phase mixtures, making it widely used in industries such as chemical, pharmaceutical, food, petroleum, and bioengineering.

[0003] The existing disc separator lifting device needs to frequently adjust the short-link chain assembly during the actual lifting process. However, the commonly used short-link chain assembly is directly hung on the lifting device body, which makes it inconvenient to disassemble and assemble the short-link chain assembly.

[0049] Example 2

[0050] Based on Example 1, this example introduces the specific structure of the locking assembly 7 in a special lifting device for a disc separator. Figure 9As shown, the inner wall of the locking box 21 is slidably connected with an adjusting seat 33, and the adjusting seat 33 is fixedly connected to the locking rod 22. A sliding opening is opened on the outer wall of one side of the locking box 21, and the inner wall of the sliding opening is slidably connected with a pull rod 34. One end of the pull rod 34 is fixedly connected to the adjusting seat 33, and the outer wall of the pull rod 34 is sleeved with a spring 2 35. When the lifting chain 8 is installed, the pull rod 34 is pulled first, and the pull rod 34 pulls the locking rod 22 into the locking box 21 through the adjusting seat 33. When the adjusting seat 33 moves, the spring 2 35 on the pull rod 34 is directly compressed. At this time, the lifting chain 8 is directly sleeved on the locking rod 22. When the pull rod is released, the spring 2 35 drives the locking rod 22 to be inserted into the U-shaped groove 9, which facilitates the quick installation of the lifting chain 8.

[0051] Working principle: When in use, first choose the number of lifting mechanisms 4 to be used according to the actual situation of the separator. When installing the lifting mechanism 4, first insert the two adjusting components 6 into the slide 3, rotate the rotating disk 10 to drive the bidirectional screw 11 to rotate, and when the bidirectional screw 11 rotates, the two driving seats 14 are driven to move toward or away from each other. When the driving seat 14 moves, it is convenient to directly drive the L-shaped seat 13 to be inserted into the slide 3, and then rotate the rotating part 18 to drive the bidirectional screw 25 to rotate. When the bidirectional screw 25 rotates, the two threaded sleeves 26 are directly driven to move toward or away from each other. When the two threaded sleeves 26 move toward each other, they are directly pushed out of the two pressing blocks 19 through the connecting plate 24. When the two pressing blocks 19 are extended, they are pressed in the slide 3, so that the L-shaped seat 13 is conveniently fixed in the slide 3. Before fixing the L-shaped seat 13, the position of the connecting seat 5 on the lifting seat 1 can be adjusted. After the adjustment is completed, the connecting seat 5 is fixed, and then the lifting chain 8 is installed.

[0052] When the lifting chain 8 is installed in the first embodiment, the switch is directly turned on to energize the electromagnet 31. When the electromagnet 31 is energized, magnetism is generated, and the armature 32 is attracted to move toward the electromagnet 31. When the armature 32 moves, it is convenient to directly drive the locking rod 22 to be retracted into the locking box 21 through the adjustment seat 33. When the adjustment seat 33 moves, it directly compresses the spring 1 30 on the fixed rod 29. At this time, the lifting chain 8 is directly sleeved on the locking rod 22. At the same time, the electromagnet 31 is de-energized, and the two springs 1 30 directly drive the locking rod to be inserted into the U-shaped groove 9, thereby facilitating the quick installation of the lifting chain 8.

[0053] When installing the lifting chain 8 in Example 2, first pull the pull rod 34, and the pull rod 34 pulls the locking rod 22 into the locking box 21 through the adjustment seat 33. When the adjustment seat 33 moves, it directly compresses the spring 2 35 on the pull rod 34. At this time, the lifting chain 8 is directly connected to the locking rod 22. When the pull rod is released, the spring 2 35 drives the locking rod 22 to be inserted into the U-shaped groove 9, thereby facilitating the quick installation of the lifting chain 8.
