Description

Technical Field

[0001] The utility model relates to the technical field of cyclones, and in particular to a slot-type flange for accurately aligning an overflow elbow. Background Art

[0002] The overflow elbow of a cyclone is a crucial component. To facilitate adjustment of the overflow elbow's installation angle, its mounting flanges are designed to be used in conjunction with live and dead flanges. The live flange is used on the overflow elbow, while the dead flange is used on the short-circuit. However, due to unskilled installation workers and difficulty aligning the overflow elbow and the short-circuit, installation deviations can easily occur, causing the overflow elbow and short-circuit to misalign, increasing wear on the overflow elbow and short-circuit, and reducing their service life. Utility Model Content

[0003] The purpose of the utility model is to provide a slot-type flange for accurately aligning the overflow elbow, aiming to solve the technical problems in the prior art that the overflow elbow and the short-circuit are easily misaligned during installation, which increases the wear of the overflow elbow and the short-circuit and reduces the service life of the overflow elbow and the short-circuit.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A slot-type flange is used for accurately aligning an overflow elbow. The slot-type flange is slidably sleeved on the overflow elbow. A flange is coaxially provided at the discharge end of the overflow elbow. An annular slot for the flange to be inserted is coaxially opened at the bottom of the slot-type flange.

[0006] Compared with traditional flanges, the slot-type flange is provided with a slot on the movable flange so that the slot-type flange can be clamped on the flange of the overflow elbow, so that the slot-type flange and the overflow elbow remain in a coaxial state, so that the overflow elbow and the short circuit assembled together by the slot-type flange and the dead flange are maintained in the center position, and workers do not need to laboriously observe whether the overflow elbow is in the center, avoiding the overflow elbow and the short circuit from being misaligned during installation, and reducing equipment life problems caused by installation operation errors.

[0007] Preferably, the slot-type flange includes an annular limiting platform and a flange platform provided on the annular limiting platform, the annular slot is provided on the limiting platform, a plurality of limiting protrusions are provided on the top of the annular limiting platform, and a plurality of limiting grooves for the limiting protrusions to engage with are provided on the flange platform. The slot-type flange is provided as two parts, the annular limiting platform and the flange platform, so that when the slot-type flange is worn due to adjustment of the angle of the overflow elbow, resulting in the overflow elbow being unable to maintain a central position, only the annular limiting platform can be replaced, saving costs. The limiting protrusions and the limiting grooves cooperate to allow the flange platform and the annular limiting platform to rotate in the same direction.

[0008] Preferably, the flange platform is provided with a receiving groove for receiving the annular limiting platform. The provision of the receiving groove facilitates the placement of the flange platform on the annular limiting platform.

[0009] Preferably, the annular stopper is composed of two semi-annular platforms, and the limiting protrusion is provided on the semi-annular platform. The annular stopper is composed of two semi-annular platforms, so that when the groove is worn and the overflow elbow cannot be properly aligned, the flange platform is lifted upward to remove the two semi-annular platforms, thereby facilitating the replacement of the annular stopper.

[0010] Preferably, the two semi-annular platforms are butted end to end. The two semi-annular platforms are butted end to end to facilitate the connection of the two semi-annular platforms.

[0011] Preferably, a groove is provided at the tail end of the semi-annular platform, and a boss is provided at the head end of the semi-annular platform extending into the groove. The groove and the boss cooperate to facilitate the docking of the two semi-annular platforms.

[0012] Preferably, the head end of the boss is arranged in an arc shape, which can facilitate the boss to be inserted into the groove.

[0013] Preferably, the limiting protrusions on the two semi-annular platforms are symmetrically arranged. The symmetrical arrangement of the limiting protrusions on the two semi-annular platforms can further ensure the alignment of the annular limiting platform and the flange platform, and further ensure that the overflow elbow cannot be maintained in the center position.

[0014] After adopting the above technical solution, the beneficial effects of the utility model are:

[0015] Compared with traditional flanges, the slot-type flange is provided with a slot on the movable flange so that the slot-type flange can be clamped on the flange of the overflow elbow, so that the slot-type flange and the overflow elbow remain in a coaxial state, so that the overflow elbow and the short circuit assembled together by the slot-type flange and the dead flange are maintained in the center position, and workers do not need to laboriously observe whether the overflow elbow is in the center, avoiding the overflow elbow and the short circuit from being misaligned during installation, and reducing equipment life problems caused by installation operation errors.

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] The orientations mentioned in this specification are based on the orientations of the slot-type flange for accurately aligning the overflow elbow of the present invention during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0024] Example 1:

[0025] like Figure 1 and Figure 2 The figure shows a slot-type flange for precisely aligning an overflow elbow. The slot-type flange 1 is slidably mounted on the overflow elbow 2. A flange 20 is coaxially provided at the discharge end of the overflow elbow 2. The bottom of the slot-type flange 1 is coaxially provided with an annular slot 10 for the flange 20 to engage. A short circuit 3 is used to connect the cyclone and the overflow elbow 2. The short circuit 3 is provided with a dead flange 30. The slot-type flange 1 and the dead flange 30 are assembled with bolts and nuts to secure the overflow elbow 2 to the short circuit 3, thereby securing the overflow elbow 2 to the cyclone.

[0026] Compared with the traditional flange, the slot-type flange 1 is provided with a slot on the movable flange so that the slot-type flange 1 can be clamped on the flange 20 of the overflow elbow 2, so that the slot-type flange 1 and the overflow elbow 2 remain in a coaxial state, so that the overflow elbow 2 and the short-circuit 3 assembled together by the slot-type flange 1 and the dead flange 30 are maintained in the center position, and workers do not need to laboriously observe whether the overflow elbow 2 is in the center, thereby avoiding the overflow elbow 2 and the short-circuit 3 from being misaligned during installation, and reducing equipment life problems caused by installation operation errors.

[0027] Example 2:

[0028] like Figure 3 and Figure 4As shown, a slot-type flange for precisely aligning an overflow elbow is shown. The slot-type flange 1 is slidably mounted on the overflow elbow 2. A flange 20 is coaxially provided at the discharge end of the overflow elbow 2, and an annular slot 10 is coaxially formed at the bottom of the slot-type flange 1 for the flange 20 to engage. A short circuit 3 is used to connect the cyclone and the overflow elbow 2. The short circuit 3 is provided with a dead flange 30. The slot-type flange 1 and the dead flange 30 are assembled with bolts and nuts to secure the overflow elbow 2 to the short circuit 3.

[0029] The slot-type flange 1 includes an annular limiting platform and a flange platform 11 provided on the annular limiting platform. The annular slot 10 is provided on the limiting platform. A plurality of limiting protrusions 12 are provided on the top of the annular limiting platform. The flange platform 11 is provided with a plurality of limiting grooves 110 for the limiting protrusions 12 to engage with. The slot-type flange 1 is configured as two parts, the annular limiting platform and the flange platform 11. When the slot-type flange 1 is worn due to adjustment of the angle of the overflow elbow 2, resulting in the overflow elbow 2 being unable to maintain the center position, only the annular limiting platform can be replaced, saving costs. The limiting protrusions 12 and the limiting grooves 110 cooperate to allow the flange platform 11 and the annular limiting platform to rotate in the same direction.

[0030] Among them, the flange platform 11 is provided with a receiving groove 111 for receiving the annular limiting platform. The arrangement of the receiving groove 111 facilitates the arrangement of the flange platform 11 on the annular limiting platform.

[0031] The annular stopper is composed of two semi-annular platforms 13, and the limiting protrusion 12 is provided on the semi-annular platforms 13. The annular stopper is composed of two semi-annular platforms 13, so that when the groove is worn and the overflow elbow 2 cannot be correctly aligned, the flange platform 11 is lifted upward to remove the two semi-annular platforms 13, making it easier to replace the annular stopper.

[0032] The two semi-annular platforms 13 are butted end to end, which facilitates the connection of the two semi-annular platforms 13.

[0033] As a preferred example of this embodiment, the limiting protrusions 12 on the two semi-annular platforms 13 are symmetrically arranged. The symmetrical arrangement of the limiting protrusions 12 on the two semi-annular platforms 13 can further ensure the alignment of the annular limiting platform and the flange platform 11, and further ensure that the overflow elbow 2 cannot be maintained in the center position.

[0034] Example 3:

[0035] like Figure 5 As shown, the difference between this embodiment and the second embodiment is that a groove 130 is formed at the tail end of the semi-annular platform 13, and a boss 131 is formed at the head end of the semi-annular platform 13 that extends into the groove 130. The groove 130 and the boss 131 cooperate to facilitate the docking of the two semi-annular platforms 13.

[0036] As a preferred example of this embodiment, the head end of the boss 131 is arranged in an arc shape. The head end of the boss 131 is arranged in an arc shape, which can facilitate the boss 131 to be inserted into the groove 130.

[0037] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples.
