Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, and particularly relates to a fixing mechanism for a centrifuge filter bag which is convenient for disassembly and assembly. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate the components in a mixture of liquid and solid particles or liquid and liquid. Centrifuges are mainly used to separate solid particles from a suspension liquid, or to separate two immiscible liquids with different densities in an emulsion. It can also be used to remove liquid from wet solids.

[0003] In the prior art, for example, a filter bag centrifuge with Chinese patent number CN115400884A includes a housing, an upper cover, a drum, a first telescopic filter ring and a drum sleeve. The upper cover is arranged on the housing, the drum is arranged in the housing, the drum sleeve is slidably connected in the drum, and the upper part of the first telescopic filter ring is tightly connected with the inner wall of the upper part of the drum through an elastic pressing member.

[0004] In the prior art, a filter bag is fixedly connected in a filter bag centrifuge. In the prior art, the filter bag is generally fixed in the drum by bolts, and the replacement process is relatively cumbersome. However, the filter bag in the centrifuge needs to be replaced frequently, and the complex replacement process slows down the working efficiency of the centrifuge.

[0029] Working principle:

[0030] During use, the filter bag body 2 is sleeved on the surface of the rotary drum 1, then the limiting component 3 is aligned with the rotary drum 1. Next, the limiting frame 31 is slid downward along the surfaces of the rotary drum 1 and the filter bag body 2. The limiting frame 31 drives the rubber pad 32 and the clamping component 33 to slide downward. The limiting frame 31 drives the sealing strip 335 to contact the top of the filter bag body 2. The sealing strip 335 enhances the sealing performance between the limiting frame 31 and the filter bag body 2. The roller 333 in the clamping component 33 presses against the filter bag body 2. The roller 333 receives the reaction force exerted by the filter bag body 2 and applies pressure to the sliding bin 332. The sliding bin 332 slides along the sliding groove 334. The sliding bin 332 drives the return spring 331 to compress. Under the action of its own elastic force, the return spring 331 drives the sliding bin 332 and the roller 333 to tightly press against the filter bag body 2;

[0031] The fixing belt 42 in the fixing component 4 is drawn out to an appropriate length so that the fixing belt 42 tightly adheres to the surface of the rotary drum 1. The clamping block 43 prevents the fixing belt 42 from being pulled out of the locking component 41. Then, the threaded rod 412 in the locking component 41 is rotated. The threaded rod 412 drives the fixing plate 413 to move towards the fixing belt 42. The fixing plate 413 presses against the fixing belt 42 to prevent the fixing belt 42 from moving;

[0032] When the filter bag needs to be removed, the threaded rod 412 is rotated in the reverse direction. The threaded rod 412 drives the fixing plate 413 to move away from the fixing belt 42. A part of the fixing belt 42 is drawn out in the reverse direction along the fixing bin 411. At this time, the fixing belt 42 releases the rotary drum 1. The limiting component 3 and the fixing component 4 are pulled out upward. The limiting component 3 and the fixing component 4 move away from the rotary drum 1. Then, the filter bag body 2 is taken out, the filter bag is replaced, and the above steps are repeated.

[0033] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art without special instructions and limitations.
