Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a vertical centrifuge with a filter bag fixing device. Background Technology

[0002] A vertical centrifuge is a highly efficient solid-liquid separation device, consisting of a feeding device, a separation system, a filter chamber, a discharge chamber, a transmission system, a washing device, and an electrical control device. During the operation of a vertical centrifuge, the filter bag, as a filtration medium, plays a crucial role. Solid particles in the suspension are thrown towards the filter bag by centrifugal force, while the liquid passes through the filter bag to form filtrate. In this way, the solid and liquid are effectively separated, achieving the goal of solid-liquid separation.

[0003] However, in the existing technology, at least the following technical problems have been found: the filter bags in traditional vertical centrifuges are usually just laid flat on the inner wall of the drum, and the bag opening is rolled up and laid on the liquid-blocking plate at the upper end of the drum. However, there is no special fixing device on the liquid-blocking plate. When the centrifuge is running, the drum rotates at high speed, and the filter bags are subjected to various forces such as centrifugal force and material impact force, which can easily cause them to move left and right and fall. Therefore, we provide a vertical centrifuge with a filter bag fixing device. Utility Model Content

However, there is no dedicated fixing device on the liquid-blocking plate. When the centrifuge is running, the drum rotates at high speed, and the filter bags are subjected to various forces such as centrifugal force and material impact force, which can easily cause the filter bags to move left and right or fall.

[0027] This application provides a vertical centrifuge with a filter bag fixing device. By setting a fixing component, under the cooperation of a fixing block, a positioning bolt, a connecting plate, a guide rod, and a magnetic block, rotating the positioning bolt causes it to move towards the insert plate. Under the restriction of the guide rod, the connecting plate drives the magnetic block into the positioning hole, thus achieving complete fixing of the insert plate. By setting a magnetic block and a magnetic plate, the magnetic block and the magnetic plate attract each other, which can prevent the positioning bolt from loosening, thereby improving the fixing effect of the connecting ring.

[0028] Example 1

[0029] The technical solution in this application embodiment effectively solves the problem that filter bags in traditional vertical centrifuges are usually simply laid flat on the inner wall of the drum, with the bag openings rolled up and laid on the liquid-blocking plate at the upper end of the drum. However, there is no dedicated fixing device on the liquid-blocking plate. When the centrifuge is running, the drum rotates at high speed, and the filter bags are subjected to various forces such as centrifugal force and material impact force, which easily leads to lateral movement and falling. The overall idea is as follows:

[0030] like Figures 1 to 4To address the problems existing in the prior art, this utility model provides a vertical centrifuge with a filter bag fixing device, including a drum 1. A mounting ring 102 is fixedly connected to the top of the drum 1. A connecting ring 3 is disposed above the mounting ring 102. A filter bag 2 is fixedly connected to the bottom end of the connecting ring 3. Multiple water-permeable holes 101 are formed on the surface of the drum 1. Insert plates 103 are fixedly connected to both sides of the top of the mounting ring 102. Slots 31 corresponding to the insert plates 103 are formed on both sides of the surface of the connecting ring 3. A fixing component 32 is disposed above the connecting ring 3 and near the slots 31. The insert plate 103 has two positioning holes 1031 on the side near the fixing component 32. The fixing component 32 includes a fixing block 321, which is fixedly connected above the connecting ring 3 and near the slot 31. The fixing block 321 has a positioning bolt 322 connected to its internal thread. One end of the positioning bolt 322 is connected to a connecting plate 323 via a bearing. Two magnetic blocks 325 corresponding to the size of the positioning holes 1031 are fixedly connected to one side of the connecting plate 323. A guide rod 324 that slides and engages with the fixing block 321 is fixedly connected to one side of the connecting plate 323.

[0031] By adopting the above technical solution, when fixing the filter bag 2, the connecting ring 3 is first placed above the mounting ring 102, and the insert plate 103 is inserted into the two slots 31 on the surface of the connecting ring 3, which can initially fix the connecting ring 3. At the same time, the filter bag 2 is laid on the inner wall of the drum 1, and the positioning bolt 322 is rotated, so that the positioning bolt 322 moves towards the insert plate 103. Under the restriction of the guide rod 324, the connecting plate 323 drives the magnetic block 325 into the positioning hole 1031, which can completely fix the insert plate 103.

[0032] Specifically, a magnetic plate 326 with opposite magnetism to that of the magnetic block 325 is fixedly connected to the inner side of the positioning hole 1031.

[0033] By adopting the above technical solution, the magnetic block 325 and the magnetic plate 326 attract each other, which can prevent the positioning bolt 322 from loosening, thereby improving the fixing effect on the connecting ring 3.

[0034] Working principle: When fixing the filter bag 2, first place the connecting ring 3 above the mounting ring 102, and insert the insert plate 103 into the two slots 31 on the surface of the connecting ring 3, which can initially fix the connecting ring 3. At the same time, the filter bag 2 is laid on the inner wall of the drum 1. Rotate the positioning bolt 322, so that the positioning bolt 322 moves towards the insert plate 103. Under the restriction of the guide rod 324, the connecting plate 323 drives the magnetic block 325 into the positioning hole 1031, which can completely fix the insert plate 103. At the same time, the magnetic block 325 attracts the magnetic plate 326, which can prevent the positioning bolt 322 from loosening, thereby improving the fixing effect of the connecting ring 3. When the drum 1 is rotating, it can prevent the filter bag 2 from moving left and right or falling. Similarly, by forcefully rotating the positioning bolt 322 in the opposite direction, the filter bag 2 can be removed.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
