Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization, in particular to a fixing device for a spray pipe of a traveling spray dust collector. Background Art

[0002] At present, with the improvement of environmental protection requirements and the upgrading of production technology, a clean and tidy workshop working environment is paid more and more attention. To meet the dust collection generated by production and the requirements of some production processes, dust collectors have been widely used in industrial production. Due to its superior performance, the traveling spray dust collector has a relatively high usage rate in industry. The spray system of the traveling spray dust collector is as Figure 1 , 4 shown, mainly composed of an air bag 12, an air bag support 13, a pulse valve 14, a spray pipe elbow 10, a spray pipe 9, and a spray pipe fixing device b. Among them, the air bag 12, the air bag support 13, the spray pipe elbow 10, and the spray pipe fixing device b are all firmly welded to the dust collector body 8 and will not move during the spray process of the dust collector; the pulse valve 14 and the air bag 12 are fixed by bolts and basically will not move either; only the spray pipe 9 cannot be welded and fixed due to the consideration of bag repair and must have the function of being removable at any time. As Figure 4 shown, the existing fixing method of the spray pipe is to weld an angle iron 15 at the tail of the spray pipe and fix it with bolts 16 and a fixing piece 17. However, during the actual spray process, the spray of the pulse valve 14 will generate a lateral load. In this connection method, finally, the bolts 16 will be subjected to the same shear force, and this force reciprocates and impacts with a relatively high frequency. After a long working time, the bolts 16 will break, resulting in the displacement of the spray pipe, and then the spray effect will fail, and the dust collector cannot work normally. In severe cases, it will cause production suspension and maintenance, resulting in huge economic losses. Summary of the Invention

[0003] The invention object of the utility model is to provide a fixing device for a spray pipe of a traveling spray dust collector, which can absorb part of the lateral load generated by the spray pipe during the operation of the pulse valve with a buffer pad and be borne by a welded steel structure, reduce the risk of fracture of connecting parts, extend the service life of the spray pipe, and does not affect the convenient and quick replacement of the bag.

[0004] The fixing device of the blowing pipe of the blowing dust collector of the utility model is realized in this way, including an upper fixed channel steel, a lower fixed channel steel, an upper fixed plate, a lower fixed plate, a triangular reinforcing rib, a buffer pad, and a cylindrical pin. The upper fixed channel steel and the lower fixed channel steel are respectively connected to the upper and lower sides of the dust collector body, the upper fixed plate and the lower fixed plate are connected to the blowing pipe through the triangular reinforcing rib, and the upper fixed plate and at least one of the upper fixed channel steel and the lower fixed plate and the lower fixed channel steel are connected together through the cylindrical pin, so that the blowing pipe is always integrated with the dust collector body during the blowing process and the blowing pipe cannot be radially rotated; the buffer pad is arranged between the upper fixed plate and the upper fixed channel steel, or the buffer pad is arranged between the lower fixed plate and the lower fixed channel steel, so that the lateral load generated during the blowing can be absorbed during the blowing.

[0005] When the dust collector is in normal use, the upper and lower fixed channel steels will support the upper and lower fixed plates of the blowing pipe. The lateral load generated during the blowing process is partially absorbed by the buffer pad to reduce the impact on the upper and lower fixed channel steels. The cylindrical pins ensure that the blowing pipe will not rotate radially and ensure that the blowing pipe will not move.

[0006] Compared with the prior art, the utility model has the advantages of being able to absorb part of the lateral load generated by the blow pipe when the pulse valve is working by the buffer pad and being borne by the welded steel structure, thereby reducing the risk of breakage of the connecting parts, extending the service life of the blow pipe, and not affecting the convenient and quick replacement of the bag.

Detailed implementation manners

[0014] Now, in combination with the attached drawings and embodiments, the fixing device for the injection pipe of the injection dust collector of the present utility model will be further described in detail:

[0015] As Figures 1-3 shown, the fixing device for the injection pipe of the injection dust collector of the present utility model is realized as follows. It includes an upper fixing channel steel 1, a lower fixing channel steel 2, an upper fixing plate 3, a lower fixing plate 4, a triangular reinforcing rib 5, a buffer pad 6, and a cylindrical pin 7. The upper fixing channel steel 1 and the lower fixing channel steel 2 are respectively connected to the upper and lower parts of the dust collector body 8. The upper fixing plate 3 and the lower fixing plate 4 are connected to the injection pipe 9 through the triangular reinforcing rib 5. At least one of the upper fixing plate 3 and the upper fixing channel steel 1, and the lower fixing plate 4 and the lower fixing channel steel 2 are connected together through the cylindrical pin 7, so that the injection pipe 9 and the dust collector body 8 always form an integral body during the injection process and the injection pipe 9 cannot rotate radially; the buffer pad 6 is arranged between the upper fixing plate 1 and the upper fixing channel steel 3, or the buffer pad 6 is arranged between the lower fixing plate 2 and the lower fixing channel steel 4. In this way, the lateral load generated during injection can be absorbed during injection. The distance between the upper fixing channel steel 1 and the lower fixing channel steel 2 is greater than the width of the upper fixing plate 3 and the lower fixing plate 4, and the distance between the upper fixing channel steel 1 and the lower fixing channel steel 2 is greater than the outer diameter of the injection pipe 9.

[0016] When the dust collector is in normal use, the upper fixing channel steel 1 and the lower fixing channel steel 2 will abut against the upper fixing plate 3 and the lower fixing plate 4 of the injection pipe 9. Part of the lateral load generated during the injection process is absorbed by the buffer pad 6, reducing the impact on the upper fixing channel steel 1 and the lower fixing channel steel 2. The cylindrical pin 7 ensures that the injection pipe 9 will not rotate radially and ensures that the injection pipe 9 does not move in position.

[0017] As Figure 5 shown, when it is necessary to repair the filter bag, loosen the union joint 11 connected to the injection pipe elbow 10, remove the cylindrical pin 7, use a pipe wrench to rotate the injection pipe 9 counterclockwise by 90°, then retreat the injection pipe 9 so that the pipe head of the injection pipe 9 exits the injection pipe elbow 10, and the injection pipe 9 can move laterally. Then rotate the injection pipe 9 clockwise by 90° and move it to one side to facilitate the replacement of the filter bag ( Figure 6 the state shown). After replacing the filter bag, it can be installed back to the original position in the reverse manner of disassembling the injection pipe 9.
