[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] The following describes a fixing structure for a filter bag in a pouch centrifuge according to an embodiment of the present invention, with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown in the figure, a fixing structure for a filter bag of a pouch centrifuge according to an embodiment of the present invention includes: a shell 1, a mounting ring 2, a filter bag 3, and a mounting mechanism 4, wherein the mounting mechanism 4 includes a connecting shell 43, a fixing component 46, and a slider 49.

[0025] The mounting ring 2 has a first sliding groove 41, a fixing groove 42 is formed in the first sliding groove 41, a connecting shell 43 is set in the mounting ring 2, a fixing component 46 is set on the mounting ring 2, sliders 49 are respectively set on the outer wall of the connecting shell 43, a second sliding groove 44 is formed in the connecting shell 43, a slide rail 45 is set on the outer wall of the filter bag 3, a fixing ring 47 is set on the mounting ring 2, and a limit block 48 is respectively set at the bottom of the fixing ring 47.

[0026] Specifically, when installing the filter bag 3, the slide rail 45 is fixed to the outside of the filter bag 3, and then the slide rail 45 is installed in the second slide groove 44 inside the connecting shell 43. The connecting shell 43 is inserted into the first slide groove 41 by the external slider 49 and rotated so that it is inserted into the fixing groove 42. Then the limiting block 48 on the fixing ring 47 is inserted into the first slide groove 41, so that the slider 49 is fixed in the fixing groove 42.

[0027] In one embodiment of this application, such as Figure 2 The fixing component 46 shown includes a latch 462 and a first spring 463.

[0028] The fixing groove 42 is provided with mounting holes 461, the latches 462 are respectively set in the corresponding mounting holes 461, the first springs 463 are respectively set in the corresponding mounting holes 461, and the other end of the first springs 463 are respectively connected to the corresponding latches 462. The slider 49 is provided with limit holes 464.

[0029] Specifically, when the slider 49 is inserted into the fixing groove 42, the slider 49 will press the bolt 462 into the mounting hole 461. Then, as the slider 49 is fixed, the limiting hole 464 on the slider 49 is aligned with the mounting hole 461. At this time, the bolt 462 is ejected from the mounting hole 461 into the limiting hole 464 under the action of the first spring 463, thus completing the fixing.

[0030] When the filter bag 3 needs to be replaced, pull the latch 462 to pull the latch 462 out of the limiting hole 464, then rotate the connecting shell 43 so that the slider 49 slides into the first sliding groove 41, and then the filter bag 3 can be taken out for replacement.

[0031] In one embodiment of this application, such as Figure 3 and Figure 4 A limit component 5 is provided on the fixed ring 47 shown.

[0032] The limiting assembly 5 includes a connecting rod 51, a fixing bolt 52, a second spring 54, a lever 55, a telescopic rod 57, a third spring 58, and a limiting bolt 59.

[0033] One end of the connecting rod 51 passes through the fixing ring 47 and is connected to the fixing bolt 52. The other end of the connecting rod 51 is connected to the lever 55. The second spring 54 is sleeved on the outside of the connecting rod 51. One end of the second spring 54 is connected to the fixing ring 47, and the other end of the second spring 54 is connected to the lever 55. A connecting groove 56 is provided on the mounting ring 2. The telescopic rod 57 is set in the connecting groove 56. The third spring 58 is sleeved on the outside of the telescopic rod 57. One end of the third spring 58 is connected to the inner wall of the connecting groove 56, and the other end of the third spring 58 is connected to the limit bolt 59. A sliding shell 511 is provided on the outside of the connecting rod 51. An isolation column 53 is fixed on the outside of the connecting rod 51. A connecting hole 510 is provided on the fixing ring 47.

[0034] Specifically, when using the limiting block 48 on the fixing ring 47 to restrict the slider 49, the limiting block 48 and the fixing bolt 52 on the fixing ring 47 are aligned with the first sliding groove 41 and the connecting groove 56 respectively and inserted. At this time, the push block 55 is pressed, and the push block 55 pushes the fixing bolt 52 into the connecting groove 56 through the connecting rod 51. At this time, the limiting bolt 59 is squeezed into the connecting groove 56 under the action of the third spring 58, so that when the fixing bolt 52 passes the limiting bolt 59, the sliding shell 511 will not pass the limiting bolt 59, thereby completing the fixing of the fixing ring 47.

[0035] When the filter bag 3 needs to be replaced, press the lever 55 again. The lever 55 pushes the fixing bolt 52 into the connecting groove 56 through the connecting rod 51, and pushes the sliding shell 511 inward through the isolation column 53 on the connecting rod 51. The sliding shell 511 squeezes the limiting bolt 59, thereby removing the fixing bolt 52 from the connecting groove 56 and releasing the fixing ring 47.

[0036] Working principle: When installing the filter bag 3, the slide rail 45 is fixed to the outside of the filter bag 3. Then, the slide rail 45 is installed in the second slide groove 44 inside the connecting shell 43. The connecting shell 43 is inserted into the first slide groove 41 by the external slider 49 and rotated to lock into the fixing groove 42. Then, the limiting block 48 on the fixing ring 47 is inserted into the first slide groove 41, so that the slider 49 is fixed in the fixing groove 42. When the slider 49 is locked into the fixing groove 42, the slider 49 will squeeze the latch 462 into the mounting hole 461. Then, as the slider 49 is fixed, the limiting hole 464 on the slider 49 aligns with the mounting hole 461. At this time, the latch 462 is ejected from the mounting hole 461 into the limiting hole 464 under the action of the first spring 463, thus completing the fixation. When using the limiting block 48 on the fixing ring 47 to restrict the slider 49... At this time, the limiting block 48 and the fixing bolt 52 on the fixing ring 47 are aligned with the first sliding groove 41 and the connecting groove 56 respectively and inserted. Then, press the lever 55. The lever 55 pushes the fixing bolt 52 into the connecting groove 56 through the connecting rod 51. At this time, the limiting bolt 59 is squeezed into the connecting groove 56 under the action of the third spring 58, so that when the fixing bolt 52 passes the limiting bolt 59, the sliding shell 511 will not pass the limiting bolt 59, thus completing the fixing of the fixing ring 47. When the filter bag 3 needs to be replaced, press the lever 55 again. The lever 55 pushes the fixing bolt 52 into the connecting groove 56 through the connecting rod 51, and pushes the sliding shell 511 inward through the isolation post 53 on the connecting rod 51. The sliding shell 511 squeezes the limiting bolt 59, thereby removing the fixing bolt 52 from the connecting groove 56, and thus releasing the fixing of the fixing ring 47.

[0037] When the filter bag 3 needs to be replaced, pull the latch 462 to pull the latch 462 out of the limiting hole 464, then rotate the connecting shell 43 so that the slider 49 slides into the first sliding groove 41, and then the filter bag 3 can be taken out for replacement.

[0038] In summary, when installing and fixing the filter bag 3, the connecting shell 43 containing the filter bag 3 can be quickly installed onto the mounting ring 2 by the slider 49 and fixed by the buckle 462. Then, the limiting block 464 on the fixing ring can be used for limiting and multiple fixings can be performed in conjunction with the fixing bolt 52, so that the filter bag 3 is firmly fixed.
