Description

Technical Field

[0001] The utility model relates to the field of wear-resistant elbows, in particular to a novel wear-resistant elbow for a dust removal pipeline. Background Art

[0002] The pipe elbow is the location most severely impacted by the flowing medium, especially when the medium is smoke and dust. When the smoke and dust move to the pipe bend, the impurities in the smoke and dust will impact the bend, causing severe wear at the pipe bend.

[0003] In the prior art, a replacement pipe is installed at the pipe elbow to prevent impurities in the smoke from directly impacting the pipe bend. However, in the above method, due to the long-term use of the replacement pipe, when the replacement pipe is broken or leaking, the impurities in the smoke will act on the pipe bend. Due to the special shape of the pipe bend, the replacement pipe cannot be removed, resulting in the inability to replace the damaged replacement pipe. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 3In the embodiment of the utility model, a new type of wear-resistant elbow for a dust removal pipe includes an upper bend pipe 1 and a lower bend pipe 8 connected between two straight pipes 2. The upper bend pipe 1 and the lower bend pipe 8 form a bend structure when aligned. The docking surface of the upper bend pipe 1 and the lower bend pipe 8 is integrally formed with a connecting edge 5 protruding outward, and the two connecting edges 5 on the upper bend pipe 1 and the lower bend pipe 8 are provided with a docking mechanism; a replacement mechanism is provided at the bending part of the inner wall of the upper bend pipe 1 and the lower bend pipe 8, and the replacement mechanism is used to avoid wear at the bending part of the upper bend pipe 1 and the lower bend pipe 8 during use.

[0021] In this embodiment: during the movement of smoke and dust in the pipe, the particles or impurities contained in the smoke and dust will collide with the bend of the pipe. The collision will cause serious damage to the inner wall of the bend of the pipe. Therefore, a replacement mechanism will be added at the bend of the pipe to replace the bend, thereby avoiding direct damage to the bend of the pipe. Later, when the replacement mechanism is seriously damaged, the worn replacement mechanism can be taken out by unscrewing the bolts and nuts connected to the connecting edge 5, and then removing the upper bend pipe 1. The replacement mechanism can be replaced with a new one. After the replacement is completed, the upper bend pipe 1 can be installed back to its original position.

[0022] Please refer to Figure 1 、 Figure 2 and Figure 3 The docking mechanism includes a guide column 7, which is integrally formed at the top of the lower connecting edge 5. A connecting hole 9 is provided on the lower connecting edge 5 between two adjacent guide columns 7. The docking mechanism also includes a docking hole 6, which is provided inside the upper connecting edge 5. Multiple docking holes 6 are aligned one by one with the guide columns 7 and the connecting holes 9 in the upper and lower directions.

[0023] In this embodiment: the bolts installed on the inner wall of the docking hole 6 and the connecting hole 9 are removed, and the upper curved tube 1 is removed. During the removal process of the upper curved tube 1, the docking hole 6 plugged into the guide column 7 moves upward along the outer wall of the guide column 7 until the upper curved tube 1 is removed. Thereafter, the replacement mechanism is taken out and replaced with a new one, and the upper curved tube 1 is put back to its original position through the guide column 7, and the bolts are installed in the docking hole 6 and the connecting hole 9 aligned up and down, and the nuts are tightened to tighten.

[0024] It should be noted that a sealing ring is installed at the joint position between the upper bend pipe 1 and the lower bend pipe 8 to improve the sealing performance.

[0025] Please refer to Figure 2 and Figure 3The replacement mechanism includes a receiving groove 13 opened at the bending point of the inner wall of the upper curved tube 1 and the lower curved tube 8, and a docking groove 12 is opened at the top end of the inner wall of the upper curved tube 1 and the bottom end of the inner wall of the lower curved tube 8; the inner wall of the receiving groove 13 is clamped with a replacement pipe 10, and the upper and lower outer walls of the replacement pipe 10 are integrally formed with outwardly protruding docking strips 11. The inner wall of the receiving groove 13 coincides with the outer wall of the replacement pipe 10, and the inner wall of the docking groove 12 coincides with the outer wall of the docking strip 11.

[0026] In this embodiment: after the upper bend pipe 1 is removed, the worn replacement pipe 10 is removed, and a new replacement pipe 10 is placed in the receiving groove 13, and by adjusting the placement position of the replacement pipe 10, the replacement pipe 10 drives the docking strip 11 to be inserted into the docking groove 12, so as to achieve the placement position of the replacement pipe 10 being completely located in the receiving groove 13, thereby avoiding the problem of loose installation of the upper bend pipe 1 due to inaccurate placement of the replacement pipe 10.

[0027] Please refer to Figure 1 、 Figure 2 and Figure 3 A connecting flange 4 is welded at the docking position between the straight pipe 2 and the upper bend pipe 1 and the lower bend pipe 8, and a half flange 3 is welded at the docking position between the upper bend pipe 1 and the lower bend pipe 8 and the connecting flange 4. The two half flanges 3 aligned up and down are equal in size to the connecting flange 4 when in the docking state.

[0028] In this embodiment, when disassembling the upper bend pipe 1, first remove the bolts and nuts connecting the half flanges 3 and the connecting flanges 4 at both ends of the upper bend pipe 1, so as to release the connection between the upper bend pipe 1 and the straight pipe 2. Similarly, after the upper bend pipe 1 is connected to the lower bend pipe 8, use bolts and nuts to connect the half flanges 3 and the connecting flanges 4.

[0029] It should be noted that a seal is provided at the contact position between the half flange 3 and the connecting flange 4 to improve the sealing performance of the docking position.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
