Description

Technical Field

[0001] The utility model relates to a movable ring, in particular to a limited movable ring of a screw stacking type sludge dewatering machine, belonging to the technical field of screw stacking machines. Background Art

[0002] In the prior art, for example, the utility model with application number 202222428602.X discloses a limiting movable ring for a screw stacking sludge dewatering machine. In order to solve the problem that most of the current movable rings are light rings, which are sleeved on the outside of the spiral shaft and will rotate with the spiral shaft under the extrusion of the sludge, thereby affecting the dewatering efficiency of the screw stacking sludge dewatering machine, the limiting movable ring is provided with a claw body, and a slot is provided on the claw body, and the slot is clamped to a gasket sleeved on the screw, thereby preventing the ring body from rotating when the spiral shaft rotates. The ring body can only swing up, down, left and right, thereby ensuring a good dewatering efficiency for the screw stacking sludge dewatering machine.

[0003] Similar to the above application, there are still some shortcomings:

[0004] Although the claw body limits the ring body, the inner side of the claw body will cause sliding friction with the gasket when the ring body slides, affecting the limiting effect of the gasket on the fixing ring. In addition, friction occurs between the inner side of the ring body and the spiral shaft. When the degree of wear is large, the ring body needs to be replaced as a whole, which increases the cost of use.

[0005] Therefore, a limited floating ring of a spiral stacked sludge dewatering machine is designed to optimize the above problems. Utility Model Content

[0006] The main purpose of the utility model is to provide a limited floating ring for a spiral stacked sludge dewatering machine, in which an installation groove is opened on the inner side of the groove, and a rotating shaft is rotatably installed inside the installation groove, and a roller is fixed on the rotating shaft, and the roller protrudes into the interior of the groove, so that when the ring body moves with the spiral shaft, the inner side of the groove will not generate sliding friction with the gasket, and the rolling friction between the roller and the gasket reduces the wear of the gasket and increases the service life of the gasket. An inner ring is installed on the inner side of the ring body in a clamping manner, so that the ring body is of a split design. In the event of wear, only the inner ring needs to be replaced, which reduces the cost of use. In addition, the slot on the inner step groove of the ring body cooperates with the plug on the outer step groove of the inner ring, so that disassembly and assembly are more convenient.

[0007] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0008] A limited movable ring of a spiral stacked sludge dewatering machine comprises a ring body, a claw body uniformly arranged along the circumferential direction on the outer side of the ring body and a clamping groove opened on the outer side of the claw body, a mounting groove is opened on the inner side of the clamping groove, a rotating shaft is uniformly and vertically mounted inside the mounting groove, a rotating shaft is fixed with a rotating roller, and the rotating roller protrudes into the inside of the clamping groove.

[0009] Preferably, three groups of rollers are provided, and the rollers are respectively located at both ends and a middle position of the slot.

[0021] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0022] like Figure 1-Figure 4 As shown, the present embodiment provides a limited floating ring of a spiral stacked sludge dewatering machine, comprising a ring body 1, a claw body 2 uniformly arranged along the circumferential direction on the outer side of the ring body 1, and a clamping groove 3 opened on the outer side of the claw body 2, a mounting groove 4 is opened on the inner side of the clamping groove 3, a rotating shaft 5 is uniformly and vertically installed inside the mounting groove 4, a rotating shaft 5 is fixed on the rotating shaft 5, and the rotating roller 6 protrudes into the inside of the clamping groove 3.

[0023] Overall working principle: During installation and use, the ring body 1 is installed between two sets of fixing rings, the slot 3 on the claw body 2 is aligned with the gasket on the screw, the slot 3 will not fit with the outside of the gasket, and the gasket will limit the claw body 2. During the rotation of the spiral shaft, the continuous shaking of the ring body 1 is controlled, and the rotational force is also applied to the ring body 1 during the rotation of the spiral shaft. Therefore, the side of the slot 3 will move toward the gasket, and the rollers 6 evenly arranged on the inner side of the slot 3 will prevent the inner side of the slot 3 from contacting the gasket, and convert the sliding friction into rolling friction, which effectively reduces the wear of the gasket and ensures the service life of the gasket.

[0024] In this embodiment, three groups of rollers 6 are provided, and the rollers 6 are respectively located at both ends and the middle of the slot 3 .

[0025] Partial working principle: By using multiple groups of rollers 6, it is ensured that the card slot 3 will not contact the gasket in any direction, thereby reducing the wear on the gasket.

[0026] In this embodiment, an inner ring 7 is mounted on the inner side of the ring body 1 , and a positioning mechanism is provided between the ring body 1 and the inner ring 7 .

[0027] Partial working principle: When in use, sliding friction occurs between the inner ring 7 and the spiral blades on the spiral shaft. After long-term use, when the ring body 1 is severely worn, only the inner ring 7 needs to be replaced, which reduces the cost of use.

[0028] In this embodiment, the positioning mechanism includes a stepped groove 8, an insert block 9 and a slot 10. The inner side of the ring body 1 and the outer side of the inner ring 7 are both provided with a stepped groove 8. The stepped grooves 8 on the ring body 1 and the inner ring 7 fit together. The top of the stepped groove 8 on the inner side of the ring body 1 is evenly provided with slots 10 along the circumferential direction. The outer side of the inner ring 7 is evenly fixed with insert blocks 9 that engage with the slots 10.

[0029] Local working principle: During the assembly process, the ring body 1 is placed horizontally with the stepped groove 8 on the ring body 1 at the top, and then the stepped groove 8 at the bottom of the inner ring 7 is aligned with the stepped groove 8 on the ring body 1 and engaged with each other, and then the plug 9 is inserted into the slot 10 for fixation. After assembly, it is installed between the fixing rings. Due to the limiting effect of the fixing ring, the close fit between the ring body 1 and the inner ring 7 is guaranteed.

[0030] In this embodiment, four groups of slots 10 are provided, and the angle between adjacent slots 10 is 90°.

[0031] Partial working principle: The stability of the ring body 1 and the inner ring 7 is ensured by the mutual limitation between the multiple groups of slots 10 and the insert blocks 9.

[0032] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
